Abstract

PROBLEM TO BE SOLVED: To develop a novel engaging tool which uses oppositely facing two hook-and-loop fasteners fixed on the base material of an overlapping part of a garment or the like, which enables the hook-and-loop fasteners to be easily determined of accurate positions by a touch of fingertip sensation without seeing and to be fixed with pressurization, thereby facilitates putting-on and taking-off of clothes for people having impaired fingertip operation by adding value of positional determination to the hook-and-loop fasteners, enhancing utilization frequency.SOLUTION: Two hook-and-loop fasteners to be used oppositely faced are fixed respectively on a highly rigid thin plastic base plate. In a position close to the hook-and-loop fasteners, there are formed a recessed engaging piece for which a hole is made by punching and a projected engaging piece for which a projection is made. This hole has an open lip shape and is a larger hole with both ends constricted. The projection corresponding to the hole can be inserted by rough thrust near the upper or the lower end of the lip-shaped hole and, with the insertion made deeper thereafter, the projection reaches the maximum length of the hole and is automatically fitted therein. With this state maintained, and with the two engaging pieces pressurized so as to be paralleled, the hook-and-loop fasteners are engaged with each other maintaining the accurate positional relation.

Description

  The present invention provides a compact surface that can be securely and easily aligned with the sensation of a fingertip at an overlapped portion attached to two base materials such as cloths of clothes and the like. The present invention relates to a fastener, an engagement tool comprising a concave engagement piece provided with a surface fastener portion and a cut portion on a plastic substrate, and a convex engagement piece provided with a surface fastener portion and a projection on the plastic substrate, and It relates to a manufacturing method.

  As a conventional means for joining at the overlapping portion of two base materials, there is a normal button system composed of a button and a button hole as an easily removable means. This method is said to have been developed in England in the middle of the 18th century. There is a relatively loose button string system that engages a button-like protrusion with a narrow string somewhat earlier than that. This is a technique that was applied to samurai costumes in Japan in the early 18th century. This was mainly used for the longitudinal engagement with heavy loads because the connection was loose.

  After these coupling means were developed, ultra-small metal snap hooks were put into practical use. However, there was difficulty in positioning and it was not popular. Since then, surface fasteners have been developed up to the 20th century, and have been used under the conditions that can be used by fixing a slightly larger size to two substrates with relatively rough positioning.

  In Japan, as a coupling means developed in recent years, there is a “Kohaze” method, which is a hooking method using a combination of a metal nail shape piece and a thick thread. This is currently only used to secure the buttocks of the tabi. This limited use is due to the difficulty of work and uncertain positioning. Specifically, in the overlapped portion of the tabi, the heel part fabric is fixed in such a way that a small piece of metal sewed on the upper fabric end is held in place on the lower fabric end, but both are small. It is a member, it is difficult to confirm the position by blind touch, this overlap part must be pressed sufficiently, and even if the engagement between both is not tight, there is a possibility that it will come off during use There are some.

  A fastener that has the most room for development is a hook-and-loop fastener. Although this material is unsatisfactory, it has a track record of being attached to clothes. One of the scenes in which this hook-and-loop fastener is used is the engagement of a short moving distance between hook-and-loop fasteners and the upper part of the chest where uncertainty of position determination does not become apparent. It is used where the displacement of engagement is not noticeable. These cases are relatively small pieces. Another scene is the engagement of the lid of the bag that opens widely, the pillow cover, etc., and even if there is a shift in this engagement, it is not so noticeable. The hook-and-loop fastener that is fixed to the overlapping portion of the two base materials is often large in size, with one side being several centimeters or more, even when one hook-and-loop fastener is small.

  There is a situation in which it is difficult to use a hook-and-loop fastener in a clothing or the like where the feeling when worn is important and the appearance is worrisome, causing a displacement of the engagement. In addition, there has been a problem of an annoying sound of merriness at the time of peeling, which has existed as a problem when this hook-and-loop fastener is used for clothes and the like. However, this problem has been improved by manufacturers and released as a sound-reducing surface fastener, which has been resolved. The development of a simple engagement technique by pressing this new material has attracted attention again.

  The only method disclosed in U.S. Patents is to engage the bases with hook-and-loop fasteners after positioning. According to this method, the position of the tip is determined using the relationship between the insertion hole provided at the end of the belt-like substrate and the insertion projection, and then the hook-and-loop fastener attached to the adjacent portion is pressed to detach the substrates. Can be easily fixed. This method has problems in that it is an invention aiming at the engagement between the substrates and that it is difficult to insert and fix the tips of the substrates. In the disclosed method, it is necessary to complete the insertion and fixation while visually confirming the positional relationship between the hole and the protrusion. Looking at the shape of the disclosed holes and protrusions, a semicircular portion is provided in the center of the groove-shaped hole, and a part of the groove is widened. This shape has no effect of facilitating the insertion and fixing of the bent projections. It is judged that it is for facilitating removal of a thin groove in a punching process with ruled lines.

After the present invention, there has not been a universal design engagement means that combines the certainty of connection, the ease of operation, and the ease of positioning in the world.
A universal design that has become a global trend in recent years, but wants to make it easier to combine the placket of clothes for people with disabilities in the fingertips as the number of elderly people increases (including people with disabilities including the visually impaired) Demands arise. Various developments have been made based on this requirement.
In such a stagnation of technical development, attention has been paid to a zipper that is expensive in processing cost. However, it has been difficult to insert the chuck fixing portion at the lower end portion of the placket, and has not led to a fundamental solution. Recently, news of the developed product was released, which was released in September 2010 as a cardigan fitted with new clothing fastening means from Aeon. Although this is a conventional button system, the buttonholes are arranged obliquely to improve the fastening workability. Thus, there is a demand for the development of universal design coupling means.

  US Pat. No. 3,873,051

The present invention has been made to solve the problems of the prior art as described above, and reliably superposes the base material where the positional relationship cannot be accurately confirmed visually such as a placket of clothes, and An object of the present invention is to provide a small hook-and-loop fastener with a position fixing function by fitting that can be easily performed. Specifically, a surface fastener is fastened as an engaging means to a small concave locking piece punched out of a plastic thin board and a convex locking piece, and a hole or protrusion fitting means is separately provided in the vicinity of this. It is formed so that the position can be determined by insertion by rough blind touch. Provided is a small engagement tool with a hook-and-loop fastener that can accurately and easily attach and detach two substrates by pressing both locking pieces in parallel while maintaining this mating state, and a method for manufacturing the same. It is.
Aging societies are advancing in developed countries, including Japan, and emerging countries, and in Japan, the proportion of elderly people over the age of 65 has exceeded 23%. In such a society, people who have difficulty in fine-fingered fingertips, and clothing used by people with disabilities, such as the visually impaired, can use a cheap and simple operation instead of buttons and zippers to set the base at the correct position. There is an urgent need to develop hook-and-loop fastener applications that allow engagement of materials. There is a social need especially in the field of nursing care.

  As of 2010, attaching a hook-and-loop fastener to a garment is being performed at homes and elderly care facilities. A pair of hook-and-loop fasteners that have been punched into a round shape with a diameter of 22 mm is set and sold as a “round magic”. When this is attached to clothes, the position confirmation of both hook-and-loop fasteners is insufficient for fingertip confirmation. In general, a decorative button is attached on the outer surface of the clothes as a mark so that the attachment position of the soft hook-and-loop fastener can be confirmed with a fingertip.

The present invention solves the above-described problems, and is a surface engaging tool with an engagement position determination function.
Here, the case where a hook-and-loop fastener is used as the engaging means will be mainly described. The means of the U.S. patent disclosed as a technique relating to the alignment of the surface engaging tool is accurate as in the conventional button type when used for clothes, as mentioned above. The position confirmation by visual observation is a prerequisite. In the case of clothes, the operation is performed directly under the eyes, and it is difficult to accurately confirm this positional relationship. In addition, there is a restriction that drilling in the substrate is practically impossible.
By using the surface engagement tool of the following invention content, it is possible to engage by a blind touch at an accurate overlapping position while pressing two substrates with one hand.

  The invention according to claim 1 is a concave locking piece used by being fixed to one of the overlapping portions of the two base materials, wherein the concave shape is provided with a notch in the substrate to which the surface engaging means is fixed.

The pair of small surface engaging tools according to claim 1 or 3, wherein the fitting state is not released when the means are pressed.

  The invention according to claim 6 is the pair of small surfaces according to claim 1, wherein the peripheral edge portion of the notch portion of the concave locking piece fixed to the base material is not fixed. The present invention relates to an engagement tool.

  The invention according to claim 7 relates to the pair of small surface engaging tools according to claim 1, wherein the protrusions of the convex locking pieces fixed to the base material are not fixed.

  The invention according to claim 8 relates to the pair of small surface engagement tools according to claim 1, wherein the surface engagement tool of the engagement tool is a surface fastener.

  The invention according to claim 9 relates to the pair of small surface engagement tools according to claim 1, wherein the surface engagement tool is a snap hook in the engagement tool.

A pair of small surfaces according to claim 1, wherein the surface locking pieces are used adjacent to each other, and are arranged with different sizes or shapes of adjacent notch portions or protrusion portions. The present invention relates to an engagement tool.

  According to an eleventh aspect of the present invention, there is provided a concave locking piece comprising an engaging means part and a notch part, and a convex locking part comprising an engaging means part and a projecting part. In the engagement performed after the position of the piece is fixed, the notch portion of the concave locking piece is arranged toward the lower end of the base material, and the engaging means of the convex locking piece is on the upper side. The present invention relates to a pair of surface engaging tools, which are arranged toward an end portion of a base material.

A hook-and-loop fastener is fixed to the plastic substrate, and a concave locking piece having a notch portion having a shape capable of automatically determining the position in the vicinity thereof is formed. This incision is usually a lip-shaped punched hole in which upper and lower arcs are connected symmetrically. The convex locking piece used in opposition to the concave locking piece is obtained by fixing a surface fastener having a function of engaging with the surface fastener to a plastic substrate and inserting the hole into a portion adjacent to the surface fastener. It is composed of a convex locking piece having a projection of a shape that automatically fits.
These concave locking pieces and convex locking pieces are superposed and fixed to the ends of the two base materials to be engaged with each other, and the base materials in the expanded state are inserted at rough mating portions. By the automatic position determination according to the above, the engagement that does not cause a shift by the subsequent pressing is completed.
A hook-and-loop fastener is an excellent material that can be engaged with sufficient strength by simple pressing. However, once engaged, a considerable amount of force is required to release the engagement, so that the two fasteners can be reliably engaged with each other in a precise positional relationship by a single engagement operation. Must complete the match.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, typical embodiments of a small surface fastener with a position determining function according to the present invention will be described with reference to the drawings. 1 and 3 show a concave locking piece in which a hook-and-loop fastener according to the present invention is fixed to a plastic substrate with a double-sided adhesive tape and a notch hole is formed in the vicinity thereof. The notch used here includes a hole shape. The right figure of FIG. 1 is an example of the sewing pattern of the thread | yarn with the base material by an industrial sewing machine. FIG. 2 shows a convex locking piece provided with a hook-and-loop fastener that engages with the plastic substrate and a projection that can be fitted into the hole. The right figure is an example of a sewing pattern of a thread with a base material by an industrial sewing machine. FIG. 6 is a cross-sectional view of both locking pieces, showing that the substrate and the hook-and-loop fastener are laminated with an adhesive material. In order to manufacture the laminate in the shape of a locking piece, a hook-and-loop fastener is fixed to a thin plastic plate in a band shape, and this is punched out into a desired fitting shape or melted. This manufacturing method will be described later.

First, a detailed configuration of the locking piece will be described. The fixing of the substrate and the hook-and-loop fastener shown in FIG. 1 and FIG. 2 is usually made by a sewing method in which the hook-and-loop fastener fits on the substrate with a margin. This fixing method is classified into two types. The method shown in FIGS. 1 and 2 is to attach a surface fastener to a substrate in a label manner. Although it is the form which provided the space around the hook-and-loop fastener, there exists a form which the edge of punching and the edge of three sides of a hook-and-loop fastener become the same as another form. In the latter case, a belt-like continuous surface fastener is used for substrate molding. Both can be processed with adhesive and machined. As the engaging piece processing, it is easier to fix the surface fastener by the adhesive material processing. The disadvantage is that the sewing material is not suitable for sewing because the adhesive material gets entangled with the needle.
It is also possible to employ a method in which the surface fastener is fixed to the substrate at a part thereof (not shown). In this case, the hard part of the substrate and the soft part of the surface fastener are present in the locking piece. Even in this structure, the slipperiness and rigidity, which are the characteristics of the substrate material, can be used for fitting the hole and the protrusion, and can be adopted.

  Next, a method for fixing the formed locking piece and the base material will be described. There are three types of fixing. One of them is to sew both locking pieces, which are formed by punching, into the overlapped part of the placket of clothing with the thread of an industrial sewing machine. The second is to remove the double-sided tape release paper with strong adhesive material by the adhesive material method and fix the locking piece to the base material. The third is high frequency welding. This method is limited in the material of the base material that can be applied. In the case of the present invention, a fixing method using an adhesive material is appropriate. This method is general and will not be described.

The sewing method is a method often used when attaching a hook-and-loop fastener to clothing. First, the sewing method performed with the margin of the concave locking piece and the base material will be described. Basically, the substrate and the base material are fixed only around the surface fastener on the substrate. Not only does the surface fastener, which is the area where the peeling force is applied, stably adhere, but also sewing is performed on the tip area of the hole other than the blank part of the surface fastener, the movement of the fabric under the board during fitting is restricted. It will be. That is, the sagging of the fabric due to abutment of the protrusion to be inserted is less likely to occur. In order to exhibit the slipperiness of the cut surface of the hole in the plastic plate, it is desirable that the dough on the back surface of the concave locking piece is crumpled so that the protrusion can be easily inserted into the hole. The sewing shown in FIG. 1 shows a sewing method performed by an intermediate concave locking piece and a base material.
In a relatively soft pajamas fabric or a backpack, if the tip of the protrusion is protruded around the hole and inserted into a normal hole, the cloth tends to bend. However, a thick fabric such as a winter clothes is less likely to cause this deflection, and in this case, in order to facilitate the insertion of the protrusion, a cut is effective in the fabric under the hole.

  Next, a sewing method performed between the convex locking piece and the base material will be described. FIG. 2 shows an example of sewing convex locking pieces. Although related to the description of claim 7, it is necessary to make this portion free so that the protrusion of the locking piece can be fitted with the hole in a state of being held and held by the fingertip. Sewing is limited to the area around the hook-and-loop fastener so that the movement of this portion is not restricted by the sewing.

The shape of the locking piece will be described. The outer shape of the locking piece shown in FIGS. 1 and 2 is a square shape. And the four corners are chamfered. The advantage of the square shape is that it is easy to recognize the angle with respect to the end portion of the base material when the locking piece is attached to the base material. What is necessary is just to design so that the position of the both ends of a hole part and the base of a projection part may become parallel with respect to the cutting line at the side fastener side of a latching piece. If the corners are rounded as much as possible, the risk of the edges of the substrate damaging the fabric during washing can be reduced.
These contour shapes can be designed arbitrarily. A round shape and a rectangular shape are fundamental, and it can be said that it is preferable in terms of clothing design. Both the locking pieces in FIGS. 7 to 9 are shown as round shapes resembling buttons. These shapes and sizes vary depending on the base material to be used and the design concept such as engagement strength. This is because the round shape tends to float somewhat in use. These factors determine design conditions such as the area and shape of the hook-and-loop fastener, the number of attachments, and the like. When examining the attachment position of the engagement tool to the substrate, it is convenient for visual judgment if the cut end on the surface fastener side is straight.

  When the size of the engaging tool is determined, the convex locking piece that is an operation of gripping with the fingertip is first defined. When the size is easy to hold and the hook-and-loop fastener portion is square, an area of 15 mm × 10 mm square or more, preferably about 30 mm × 20 mm is required.

  Next, the shape and size of the hole of the concave locking piece will be described. First, as a basic shape, a description will be given of a hole for receiving insertion of a protrusion having a substantially arc-shaped tip. A substantially circular arc shape having a wide mouth as shown in FIG. This shape spreads toward the intersection of both arcs. Although this hole size depends on the size of the locking piece, the maximum length of the hole (the distance between the intersections of the upper edge and the lower edge) is about 10 mm to 40 mm, preferably 15 mm to 25 mm. Is about 5 mm to 30 mm, preferably 8 mm to 15 mm. This lip-shaped hole shape facilitates the insertion of the arcuate protrusion tip, and the position of the protrusion can be determined. In other words, the tip of the protrusion can be inserted without selecting the location of the hole.

  Next, an automatic method for determining the position of the hook-and-loop fastener will be described. Even if rough insertion work that does not specify the above insertion position is performed, that is, even if the tip of the protrusion is inserted near the top of the upper edge or lower edge of the hole, the hole of the hole is related to the characteristics of the plastic substrate. Slip occurs along the slope of the cut, leading to the maximum length of the hole to the base of the protrusion. As the tip of the protrusion is inserted deeply into the base of the protrusion, the protrusion is inserted up to the maximum length of the hole. No further insertion is possible, and the bases of the protrusions are fixed by fitting with the notches at both ends of the hole. Thereby, the direction of the protrusion part to insert is prescribed | regulated. Of course, as the maximum length of the hole becomes longer, the accuracy of the position determination function of the engaging tool is improved.

  In an engagement tool with improved accuracy of the position fix function, position the hook fasteners in advance and design them so that the two hook-and-loop fasteners match when inserted most deeply. In this case, the insertion of the hook-and-loop fastener, which is the engaging means, is always performed by this insertion.

  It is necessary to devise so that the position of the surface fastener can be stably determined. When the protrusion of the convex locking piece is raised and the hole of the concave locking piece is inserted like a fingertip, if the inclination of the protruding part in the gripping state is insufficient, the edge of the surface fasteners will be partially There is a risk of engagement. It is necessary to prevent unexpected engagement from occurring when the position is determined by fitting. As a countermeasure, the distance between the hole and the hook-and-loop fastener is set to 1 mm to 3 mm so that there is no hook-and-loop fastener at the position in contact with the lower edge of the hole.

  In addition to this, it is possible to design a shape that allows fitting of holes and protrusions. If the shape of the top edge of the hole (4) in Fig. 1 is designed to match the shape of the tip of the insertion protrusion (8), the protrusion is not inserted to the depth that reaches the maximum length of the hole. The mating state can also be obtained by inserting partway through. In this case, the protrusion at the time of insertion is slightly laid and inclined. If the locking pieces are tilted and engaged with each other while maintaining the oblique fitting state, the engagement means is hardly displaced.

  As another method for preventing the engagement at the end portions of the hook-and-loop fasteners between the two locking pieces before the position is determined, the engagement element is removed by heat melting processing at the time of fusing. It is a way to destroy. This heat melting treatment can be carried out independently as a post-treatment. If this method is taken, after fixing a hook-and-loop fastener to the whole locking piece, the part which cannot be engaged can be formed in a hook-and-loop fastener part.

  Next, examples of clothes plackets will be described with reference to FIGS. As shown in FIG. 7, in the overlapping portion of the end portion of the fabric B and the end portion of the fabric A, the hole of the concave locking piece is fixed to the fabric B toward the fabric end as shown in FIG. Secure the hook-and-loop fastener toward the fabric edge. As shown in FIG. 7, the first engaging operation is as follows. First, the hook and loop finger of the convex locking piece in A on the upper side of the overlapping portion is sandwiched between the thumb and forefinger, and the other finger is pressed against the overlapping portion of the B fabric. .

  FIG. 8 is a diagram in which the operation of engaging the hook-and-loop fasteners of the opposing locking pieces is continued and engaged by operating with fingers sandwiching the hook-and-loop fastener portions of the convex locking pieces. By operating with a finger sandwiching the hook-and-loop fastener portion of the convex locking piece, the protrusion on the fingertip is guided to the hole of the concave locking piece with the sense of a fingertip. Whether or not the protrusion is inserted to the maximum length while sliding in the hole can be detected by a change in the contact condition between the slightly hard substrates. Also, if a protrusion enters the hole in this part straight, it can be recognized by the edge of the hole and the base of the protrusion.

  FIG. 9 is a diagram in which the engagement is deeply advanced, the convex locking piece is gradually tilted, and the engaging means is pressed until it is completely parallel. Rotational slipping of the protrusion occurs in the hole, and both the locking pieces automatically overlap in a parallel state. If the shapes of the upper end arc of the hole and the tip end arc of the projection match, the initial engagement state is released at the stage of pressing both locking pieces, and both engage in a parallel state. If used, the engagement of the two base materials can be completed with one hand holding the hook-and-loop fastener portion.

A method for fixing the hook-and-loop fastener to the base material will be described. The concave locking piece and the convex locking piece are fitted in advance and engaged with each other in a normal positional relationship, and this is arranged inside the overlapping portion of the two base materials. First, the former rear release paper is removed and fixed to the inside of the substrate. Next, the latter release paper is removed and the overlapping base material is pressed and fixed. If the adhesion strength of the adhesive material on the back surface of the engagement tool is much higher than the engagement strength of the engagement tool, it is possible to stably withstand repeated engagement and separation.
The thread sewing method makes it somewhat difficult to secure the engagement tool after positioning the engagement tool on the substrate. Marked temporary sewing with a conspicuous thread is necessary. One method is to mark the mounting position in advance using a pattern paper. When the sewing of both the locking pieces to the base material is completed, the mark thread is removed.
The high-frequency welding method is excellent in easily performing the fixing after the positioning of the engaging tool at the overlapping portion of the base material.

  When the engaging tool is fixed to the base material, the direction of the engaging tool is important. You should consider the handling of the locking piece at your fingertip. In the case of clothes, it is slightly inclined at an angle that allows easy movement with respect to the end of the placket perpendicular to the body.

FIG. 4 shows a variation of the hole shape of the locking piece for obtaining the fitting for determining the automatic position. Moreover, the variation of the protrusion shape of a convex locking piece is shown in FIG. In the above description, the description has been made on the basis that the same circular arc is provided on both locking pieces. Here, various shapes that become the fitting shapes of the holes and protrusions that break this same relationship are shown.
FIG. 4 shows a shape (d) using a straight line as a part of a hole, a shape (a) using a curve protruding toward the center of the hole, or an ellipse shape (b) or an edge of a hole which is a slightly loose fit. Are shown so that the other party's protrusion can easily enter (see a). A combination of a sufficiently divergent opening and a corresponding protrusion fixed at the root provides a position confirmation function and can be designed in any hole shape.

  FIG. 5 shows some protrusion shapes of the convex locking pieces. If the position can be determined by fitting the protrusion deeply into the hole, it is not necessary to match the shape of the tip of the protrusion with the shape of the upper end of the hole. Any shape may be used as long as the fitting occurs at a certain stage of insertion and the root of the protrusion can move to the maximum length of the hole thereafter. Even if the upper edge of the hole is an arc, it is possible to adopt a shape in which a straight portion is provided at the tip of the protrusion (a, c).

  Explanation regarding claim 5 will be given. If the design is such that an overlapping portion is created by the relationship between the edge of the hole and the edge of the protrusion, the engaging pieces are brought into an interlocking state as the locking pieces are tilted to approach the parallel relationship. When it becomes more completely parallel in this state, engagement occurs between the hole portion and the hook-and-loop fastener portion. The engagement between the substrates is strengthened by the engagement at these two locations. The engagement at this hole is easily released by twisting this part with the fingertips due to the characteristics of the plastic thin plate. Therefore, it is possible to design a fitting that can determine the position based on this state.

  Up to this point, there has been a fitting relationship with one hole and one protrusion. Next, an example in which a plurality of these are provided on the locking piece is shown. FIG. 10 shows a concave locking piece in which holes are arranged in two stages in the vertical direction, and a convex locking piece in which one protrusion is inserted into a selected hole. In this case, two types of engagement positions can be selected, and the tightness of the engagement tool can be adjusted in fitting clothes or the like. It is advisable to use two types of hole edge shapes so that selection errors prior to position confirmation can be detected by fingertip operation. In this combination use, the size of the hook-and-loop fastener of the concave locking piece is set larger in the vertical direction.

FIG. 11 shows an example in which two holes are arranged in the horizontal direction. In this case, the protrusions of the convex locking pieces are also two. In this case as well, it is preferable to change the size of the hole in order to prevent an error in determining the position due to an erroneous selection operation so that an error in the insertion position can be easily detected by the fingertip. In this case, the hook-and-loop fastener is horizontally long, and automatic position determination is more reliable. Also, the engagement strength is increased.
This method of preventing a position determination error due to the erroneous selection operation also exhibits the same effect when a large number of locking pieces with one individual hole portion are used side by side.

Here, the details of the material used for manufacturing the small surface fastener will be described. Indispensable materials are hook-and-loop fasteners and plastic sheets. These are fixed in place to obtain a laminate material for punching.
A hook-and-loop fastener is a base-type hook and loop type engaging element formed by a knitting method, and two types of hook-and-loop fasteners are used facing each other. Alternatively, it is possible to use one type of engaging element typified by a mushroom-like shape, or one in which hooks and loops are mixed on the same surface fastener surface. In addition to these, as a sound reduction type, a type has been developed that suppresses the buzzing sound that occurs when two surface fasteners are peeled off. This type is suitable when a hook-and-loop fastener is used in the clothes of the present invention.
The type of the hook-and-loop fastener is not restricted, and any type that can be fixed to the substrate can be used.

For the plastic substrate, a material that is compatible with attachment methods such as a type in which an adhesive double-sided tape is fixed to the back surface, a type in which threads are sewn with an industrial sewing machine, and a high-frequency welding method are used. For sewing and fixing, it is an essential condition that the needle is good, and there is a limit to the thickness and hardness, and PP, PVDC, PET, etc. are subject to cost in the case of general-purpose resins. A sheet having a thickness of 0.2 mm to 2 mm is used. A preferred range is 0.5 mm to 1.0 mm. If it is an adhesive fixing method, a thicker one can be used.
In addition, a foamed PP sheet as a low foamed sheet is preferable for obtaining a thickness that makes it easy to obtain a feeling during fitting. As a special sheet, a resin-treated paperboard or a laminate sheet of various films can be used. If decoration is more important than cost, a glossy metal sheet, a stone plate, and the like can be used as materials if they have excellent rigidity and slipperiness when engaged. This includes wires that can be contoured.

  The manufacturing method will be described in the case of a small surface fastener in which a surface fastener is fixed to a substrate with an adhesive. An example of punching out six small square hook-and-loop fasteners shown in FIG. 12 will be described. It will be punched out leaving the release paper and sold in a bag as a product with 6 pieces. Create a layout that provides trim margins around the six hook-and-loop fasteners, and place it in a two-pitch arrangement as shown in FIG. 12, and punching is a punching die that combines concave and convex locking pieces. Punch out.

  The process arrange | positions various apparatuses so that manufacture using a continuous sheet can be performed as shown in FIG. In the manufacture of the small surface fastener, a general lamination and punching continuous process or dividing process can be applied. In the uppermost stream, a roll (12) of a plastic thin plate is put on a stand, and the thin plate of the substrate is fed out. Next, the tape is drawn out from a roll (13) of a double-sided pressure-sensitive adhesive tape for attaching an adhesive for fixing the small surface fastener to the base material, and laminated on a sheet of plastic thin plate through a pressure roll. Next, the tape of the narrow surface fastener is drawn out from the roll (14) of the surface fastener and is pressure-bonded to the previous laminate sheet. This hook-and-loop fastener is provided with a release paper, which is peeled off and transferred to the laminate sheet while being wound up. It is also possible to incorporate a device that rolls an adhesive material and dries without using a double-sided adhesive tape.

The sheet laminated on the three layers is controlled via a pressure-bonding / feeding roll (15) and a feed amount / position detector (16), and supplied to a punching machine (17). In this process diagram, the punching machine is a die press that performs intermittent punching. Next, the punched sheet enters a trimming device (18) that separates the residue from the product. A wooden mold incorporating a pressing rubber and a protruding jig is attached to this device.
Next, the punched-out locking piece is pushed out here and struck into the bucket, and is deposited in the product bucket (19). The remaining part other than the product is wound on a winding roll. Instead of this winding, it can also be bundled into a bucket as a small piece while cutting with a vertical rotary blade.

  Instead of the intermittent flat punching method shown here, it is also possible to punch using a mold with a rotary continuous device. In addition, the trimming device can also be performed by a pin-rotating type of depression and pop-up method. If there are conditions that allow mass-produced products to be manufactured as standard products, equipment with high production efficiency can be obtained.

  The above explanation is about fixing a surface fastener to a substrate having excellent rigidity and providing a fitting hole or protrusion on a part of this substrate, but an engagement function as an alternative to this surface fastener. It is possible to use a male or female snap hook made of metal or resin. The hook is generally used in a size smaller than that of a normal button, and has a size that is difficult to handle with a fingertip and is difficult to position. Because of this drawback, its use is limited and not widespread. However, these disadvantages can be eliminated by combining the engagement methods using the fitting means of the present invention. The hook group is formed in a plastic substrate (not shown). Three hooks can be easily fixed to the substrate in a zigzag manner. Hooks incorporating this method can reliably determine the positions of male and female hooks, so that a plurality of hooks can be combined at the same time and the palm can be used at the same time without fear of deviation. The hook can be fixed to the substrate by fusion or integral molding.

The present invention secures a small piece of two types of locking pieces, to which an engaging means represented by a hook-and-loop fastener is fixed, to a base material such as a soft cloth, so that the position of the rough engaging tool can be approximated with a fingertip sensation. Next, the projecting portion provided on the convex engaging piece used to face the notch provided on a part of the concave engaging piece is fitted to determine the exact position, and in this state, the hook-and-loop fastener By pressing, the locking pieces can be engaged with each other without worrying about misalignment by blind touch.
By attaching this function, it is possible to manufacture a garment that makes it easy for a disabled person or a disabled person to attach and detach.
In addition, by using this engagement tool with a hook-and-loop fastener, it is possible to increase options other than buttons and zippers that are generally used in the design of clothes that require fashionability.

  The present invention provides a compact surface that can be securely and easily aligned with the sensation of a fingertip at an overlapped portion attached to two base materials such as cloths of clothes and the like. The present invention relates to a fastener, an engagement tool comprising a concave engagement piece provided with a surface fastener portion and a cut portion on a plastic substrate, and a convex engagement piece provided with a surface fastener portion and a projection on the plastic substrate, and It relates to a manufacturing method.

  As a conventional means for joining at the overlapping portion of two base materials, there is a normal button system composed of a button and a button hole as an easily removable means. This method is said to have been developed in England in the middle of the 18th century. There is a relatively loose button string system that engages a button-like protrusion with a narrow string somewhat earlier than that. This is a technique that was applied to samurai costumes in Japan in the early 18th century. This was mainly used for the longitudinal engagement with heavy loads because the connection was loose.

  After these coupling means were developed, ultra-small metal snap hooks were put into practical use. However, there was difficulty in positioning and it was not popular. Since then, surface fasteners have been developed up to the 20th century, and have been used under the conditions that can be used by fixing a slightly larger size to two substrates with relatively rough positioning.

  In Japan, as a coupling means developed in recent years, there is a “Kohaze” method, which is a hooking method using a combination of a metal nail shape piece and a thick thread. This is currently only used to secure the buttocks of the tabi. This limited use is due to the difficulty of work and uncertain positioning. Specifically, in the overlapped portion of the tabi, the heel part fabric is fixed in such a way that a small piece of metal sewed on the upper fabric end is held in place on the lower fabric end, but both are small. It is a member, it is difficult to confirm the position by blind touch, this overlap part must be pressed sufficiently, and even if the engagement between both is not tight, there is a possibility that it will come off during use There are some.

  A fastener that has the most room for development is a hook-and-loop fastener. Although this material is unsatisfactory, it has a track record of being attached to clothes. One of the scenes in which this hook-and-loop fastener is used is the engagement of a short moving distance between hook-and-loop fasteners and the upper part of the chest where uncertainty of position determination does not become apparent. It is used where the displacement of engagement is not noticeable. These cases are relatively small pieces. Another scene is the engagement of the lid of the bag that opens widely, the pillow cover, etc., and even if there is a shift in this engagement, it is not so noticeable. The hook-and-loop fastener that is fixed to the overlapping portion of the two base materials is often large in size, with one side being several centimeters or more, even when one hook-and-loop fastener is small.

  There is a situation in which it is difficult to use a hook-and-loop fastener in a clothing or the like where the feeling when worn is important and the appearance is worrisome, causing a displacement of the engagement. In addition, there has been a problem of an annoying sound of merriness at the time of peeling, which has existed as a problem when this hook-and-loop fastener is used for clothes and the like. However, this problem has been improved by manufacturers and released as a sound-reducing surface fastener, which has been resolved. The development of a simple engagement technique by pressing this new material has attracted attention again.

  The only method disclosed in U.S. Patents is to engage the bases with hook-and-loop fasteners after positioning. According to this method, the position of the tip is determined using the relationship between the insertion hole provided at the end of the belt-like substrate and the insertion projection, and then the hook-and-loop fastener attached to the adjacent portion is pressed to detach the substrates. Can be easily fixed. This method has problems in that it is an invention aiming at the engagement between the substrates and that it is difficult to insert and fix the tips of the substrates. In the disclosed method, it is necessary to complete the insertion and fixation while visually confirming the positional relationship between the hole and the protrusion. Looking at the shape of the disclosed holes and protrusions, a semicircular portion is provided in the center of the groove-shaped hole, and a part of the groove is widened. This shape has no effect of facilitating the insertion and fixing of the bent projections. It is judged that it is for facilitating removal of a thin groove in a punching process with ruled lines.

After the present invention, there has not been a universal design engagement means that combines the certainty of connection, the ease of operation, and the ease of positioning in the world.
A universal design that has become a global trend in recent years, but wants to make it easier to combine the placket of clothes for people with disabilities in the fingertips as the number of elderly people increases (including people with disabilities including the visually impaired) Demands arise. Various developments have been made based on this requirement.
In such a stagnation of technical development, attention has been paid to a zipper that is expensive in processing cost. However, it has been difficult to insert the chuck fixing portion at the lower end portion of the placket, and has not led to a fundamental solution. Recently, news of the developed product was released, which was released in September 2010 as a cardigan fitted with new clothing fastening means from Aeon. Although this is a conventional button system, the buttonholes are arranged obliquely to improve the fastening workability. Thus, there is a demand for the development of universal design coupling means.

  US Pat. No. 3,873,051

The present invention has been made to solve the problems of the prior art as described above, and reliably superposes the base material where the positional relationship cannot be accurately confirmed visually such as a placket of clothes, and An object of the present invention is to provide a small hook-and-loop fastener with a position fixing function by fitting that can be easily performed. Specifically, a surface fastener is fastened as an engaging means to a small concave locking piece punched out of a plastic thin board and a convex locking piece, and a hole or protrusion fitting means is separately provided in the vicinity of this. It is formed so that the position can be determined by insertion by rough blind touch. Provided is a small engagement tool with a hook-and-loop fastener that can accurately and easily attach and detach two substrates by pressing both locking pieces in parallel while maintaining this mating state, and a method for manufacturing the same. It is.
Aging societies are advancing in developed countries, including Japan, and emerging countries, and in Japan, the proportion of elderly people over the age of 65 has exceeded 23%. In such a society, people who have difficulty in fine-fingered fingertips, and clothing used by people with disabilities, such as the visually impaired, can use a cheap and simple operation instead of buttons and zippers to set the base at the correct position. There is an urgent need to develop hook-and-loop fastener applications that allow engagement of materials. There is a social need especially in the field of nursing care.

  As of 2010, attaching a hook-and-loop fastener to a garment is being performed at homes and elderly care facilities. A pair of hook-and-loop fasteners that have been punched into a round shape with a diameter of 22 mm is set and sold as a “round magic”. When this is attached to clothes, the position confirmation of both hook-and-loop fasteners is insufficient for fingertip confirmation. In general, a decorative button is attached on the outer surface of the clothes as a mark so that the attachment position of the soft hook-and-loop fastener can be confirmed with a fingertip.

The present invention solves the above-described problems, and is a surface engaging tool with an engagement position determination function.
Here, the case where a hook-and-loop fastener is used as the engaging means will be mainly described. The means of the U.S. patent disclosed as a technique relating to the alignment of the surface engaging tool is accurate as in the conventional button type when used for clothes, as mentioned above. The position confirmation by visual observation is a prerequisite. In the case of clothes, the operation is performed directly under the eyes, and it is difficult to accurately confirm this positional relationship. In addition, there is a restriction that drilling in the substrate is practically impossible.

The pair of small surface engaging tools according to claim 1 or 3, wherein the fitting state is not released when the means are pressed.

  The invention according to claim 6 is the pair of small surfaces according to claim 1, wherein the peripheral edge portion of the notch portion of the concave locking piece fixed to the base material is not fixed. The present invention relates to an engagement tool.

  The invention according to claim 7 relates to the pair of small surface engaging tools according to claim 1, wherein the protrusions of the convex locking pieces fixed to the base material are not fixed.

The invention according to claim 8 relates to the pair of small surface engagement tools according to claim 1, wherein the surface engagement means of the small surface engagement device is a surface fastener.

  The invention which concerns on Claim 10 arrange | positions the notch part or the said protrusion part adjacently and arrange | positions it in the same board | substrate, or arrange | positions the said notch part or the said protrusion part on a separate board | substrate. A pair of small surfaces according to claim 1, wherein the surface locking pieces are used adjacent to each other, and are arranged with different sizes or shapes of adjacent notch portions or protrusion portions. The present invention relates to an engagement tool.

According to an eleventh aspect of the present invention, there is provided a concave locking piece including a surface engaging means and a notch portion, and a convex locking including a surface engaging means and a protrusion. A pair of these surface engaging tools that are configured by a piece and disposed on the base material, the notch portion of the concave locking piece being arranged toward the end portion of the base material on the lower side, and a convex shape. The present invention relates to a pair of small surface engaging tools characterized in that the surface engaging means of the shape locking piece is arranged toward the end of the base material on the upper side.

The surface engaging tool used by a pair of this invention is comprised by the concave locking piece (1) and the convex locking piece (7) corresponding to this. Both locking pieces are composed of a surface engaging means such as a hook-and-loop fastener (2), a substrate (5) on which the surface engaging means is mounted, and an integrated material for fixing the surface engaging means to the substrate. The board is provided with fitting means used for determining the position of the hook-and-loop fastener. This fitting means consists of a hole (3) provided in the concave locking piece and a projection (8) provided in the convex locking piece, and is used for positioning the surface engaging tool by engaging both.
The substrate is usually a plastic substrate, and a hook-and-loop fastener is fixed to the substrate, and a notch that can automatically determine the position of the hook-and-loop fastener is formed in a concave locking piece after fitting in a portion close to the substrate. This incision is usually a lip-shaped punched hole in which upper and lower arcs are connected symmetrically. In the convex locking piece used opposite to the concave locking piece, a surface fastener having a function of engaging with the surface fastener is fixed to the plastic substrate, and the hole is inserted in a portion adjacent to the surface fastener. Protrusions with a shape that fits automatically are provided.
This surface engaging tool is engaged by pressing a surface engaging means such as a hook-and-loop fastener after obtaining a fitting state with a concave locking piece and a corresponding convex locking piece. A concave locking piece that is used by selectively arranging an end-shaped hole portion of a composite type locking piece in which a hole and a protrusion are formed in the piece, and an end shape of the same type of composite type locking piece The method includes a method of fitting a convex locking piece to be used by selectively arranging the protrusions.

These concave locking pieces and convex locking pieces are superposed and fixed to the ends of the two base materials to be engaged with each other, and the expanded base materials are inserted roughly into the mating portion. The automatic position determination by the operation completes the engagement that does not cause a shift by the subsequent pressing.
A hook-and-loop fastener is an excellent material capable of engaging with sufficient strength by simple pressing. However, once engaged, a considerable amount of force is required to release the engagement, so that the two fasteners can be reliably engaged with each other in a precise positional relationship by a single engagement operation. It is desirable to complete the match . In particular, elderly people and handicapped persons who have weak hand power and are unable to move their fingertips are required to complete the engagement with a single operation of the engaging tool and with a simple operation.

Hereinafter, a typical embodiment of a small surface engaging tool with a position determining function according to the present invention will be described with reference to the drawings. 1 and 3 show a concave locking piece in which a hook-and-loop fastener of a surface engaging means according to the present invention is fixed to a plastic substrate with a double-sided adhesive tape made of an integral material, and a hole for incision is formed in the vicinity thereof. It is. The notch used here includes a hole shape. The right figure of FIG. 1 is an example of a sewing pattern of a concave locking piece with a hook-and-loop fastener by an industrial sewing machine and a base material such as fabric . Figure 2 is a convex locking piece provided with protrusions shaped to fit with the hole of the attached surface fastener engaging faces the concave locking piece.

The figure on the right is an example of a sewing pattern of a convex locking piece and a base material by an industrial sewing machine. FIG. 6 is a cross-sectional view of the thickest part of both locking pieces, showing a state where the substrate and the hook-and-loop fastener are laminated with the adhesive material (11) and are further fixed to the adhesive material with the release paper (12). In order to prevent the sewing needle from passing through a rigid plastic substrate for hand-sewing, a hook-and-loop fastener is protruded from the substrate and sewing margins (13) are provided on the left and right and lower portions of the substrate. A detailed description of the hand-sewn surface engaging tool will be given in the description of FIG.
In order to manufacture the laminate in the shape of a locking piece, a hook-and-loop fastener is fixed to a thin plastic plate in a band shape, and this is punched into a desired fitting shape and contour shape, or is cut. This manufacturing method will be described later.

First, the structure of the locking piece will be described in detail. The fixing of the substrate and the hook-and-loop fastener shown in FIG. 1 and FIG. 2 is usually made by a sewing method in which the hook-and-loop fastener fits on the substrate with a margin. This fixing method is classified into two types . The method shown in FIGS. 1 and 2 is to attach a surface fastener to a substrate in a label-attached manner. Although it is the form which provided the space around the hook_and_loop | surface fastener, there exists a form which the edge of stamping and the edge of three sides of a hook_and_loop | surface fastener become the same as another form (FIG. 3). In the latter case , it is easy in terms of manufacturing method to form the belt-shaped continuous surface fastener by fixing it to the substrate and then punching out the entire substrate.

To attach the hook-and-loop fastener to the substrate as shown in FIG. 3, both the use of an adhesive material and the sewing machine can be employed. In the locking piece manufacturing process, the adhesive material method is simple. However, there is a disadvantage that the adhesive material is easily deteriorated and peeled off by dry cleaning and water washing. Then, when the sewing needle penetrates a certain part of the adhesive material, the adhesive material adheres to and accumulates on the needle over time. In order to avoid this needle problem, it is preferable to use a narrow double-sided pressure-sensitive adhesive tape in order to limit the area where the adhesive material is present using the double-sided pressure-sensitive adhesive tape over the entire surface fastener. The needle should be penetrated without adhesive material. (See b and c in FIG. 11)

Next, a method for fixing the formed locking piece and the base material will be described. There are three types of fixing methods . One of them is to sew both locking pieces, which are formed in a desired shape by punching, onto an overlap part such as a placket of clothes with an industrial sewing machine thread. The second is a household sewing machine, which is a hand-sewn thread that is secured at the seam allowance. The third is to remove the double-sided tape release paper with strong adhesive material by the adhesive material method and fix the locking piece to the base material. The fourth is high frequency welding. This method has limitations on the applicable surface fastener and base material. When it is necessary to consider washing resistance in clothing, the normal sewing method is suitable. In the case of this invention, it demonstrates centering around the fixing method by a simple adhesive material. This method is general and will not be described in detail .

  The sewing method is a method often used when attaching a hook-and-loop fastener to clothing. First, the sewing method performed with the margin of the concave locking piece and the base material will be described. Basically, the substrate and the base material are fixed only around the surface fastener on the substrate. Not only does the surface fastener, which is the area where the peeling force is applied, stably adhere, but also sewing is performed on the tip area of the hole other than the blank part of the surface fastener, the movement of the fabric under the board during fitting is restricted. It will be. That is, the sagging of the fabric due to abutment of the protrusion to be inserted is less likely to occur.

In order to exhibit the slipperiness of the cut surface of the hole in the plastic plate, it is desirable that the fabric on the back surface of the concave locking piece bend so that the protrusion can be easily inserted into the hole. The sewing example shown in FIG. 1 shows a sewing method performed with a concave locking piece and a base material.
In a relatively soft pajamas fabric or a backpack, if the tip of the protrusion is protruded around the hole and inserted into a normal hole, the cloth tends to bend. However, a thick fabric such as a winter clothes is less likely to cause this deflection, and in this case, in order to facilitate the insertion of the protrusion, a cut is effective in the fabric under the hole.

  Next, a sewing method performed between the convex locking piece and the base material will be described. FIG. 2 shows an example of sewing convex locking pieces. Although related to the description of claim 7, it is necessary to make this portion free so that the protrusion of the locking piece can be fitted with the hole in a state of being held and held by the fingertip. Sewing is limited to the area around the hook-and-loop fastener so that the movement of this portion is not restricted by the sewing.

An outline of the shape of the locking piece will be described. The contour of the corner portion of the locking piece shown in FIGS. 1 and 2 is square. And the 4 corner wearing a chamfered Earl. The advantage of this rectangular shape is that it is easy to confirm the position and recognize the angle with respect to the end of the base material when the locking piece is attached to the base material. What is necessary is just to design so that the position of the both ends of a hole part and the base of a projection part may become parallel with respect to the cutting line at the side fastener side of a latching piece. If the corners are rounded as much as possible, the risk of the edges of the substrate damaging the fabric during washing can be reduced.
The overall contour of the substrate can be designed arbitrarily, including the shape of the protrusions and holes. It is basically round and rectangular, and is easy to use for clothing as a general-purpose item. This shape design can be designed and produced in any original shape desired by the customer by using a cutting device with a laser or vibrating blade that operates in conjunction with the design design software. Compared to conventional buttons and chucks, the production according to individual needs is relatively easy.

Both the locking pieces in FIGS. 7 to 9 are shown as round shapes resembling buttons. These shapes and sizes vary depending on the base material to be used and the design concept such as engagement strength. The round shape resembles the shape of a button, but has a feature that the end of the hook-and-loop fastener is somewhat more likely to float in use . The design conditions such as the area and shape of the hook-and-loop fastener, the number of attachments, etc. are determined in consideration of these factors of design and engagement strength . When examining the attachment position of the engagement tool to the base material, it is convenient for visual judgment if the cut end on the surface fastener side is partially straight.

When deciding the size of the surface engaging member would convex form locking pieces to be working for gripping with the fingertips is defined above. When the size is easy to hold and the fitting operation is easy , and the hook-and-loop fastener portion is a square shape, this portion needs to have an area of 15 mm × 10 mm square or more, preferably about 30 mm × 20 mm. The maximum size is 100 mm × 50 mm.

Next, the shape and the hole size of the concave locking piece will be described in detail. First, as a basic shape, a description will be given of a hole for receiving insertion of a protrusion having a substantially arc-shaped tip. A substantially circular arc shape having a wide mouth as shown in FIG. This shape spreads toward the intersection of both arcs. Depending on the size of the hole size engaging piece, the maximum hole length (distance between the intersections of the upper edge and the lower edge portion) is about 40mm from 10 mm, preferably in the range of 15mm to 25 mm, this the width in the direction perpendicular to the 30mm order of 5mm at the maximum section, preferably preferably in the range of 15mm from 8 mm.

By making this lip-shaped wide hole shape, it becomes easy to insert the tip of the arc-shaped protrusion, and the fitting state can be determined by the sense of the fingertip that holds the protrusion . In other words, the location of the hole can be confirmed by rough visual confirmation, and it is not necessary to visually confirm until the final polymerization / adhesion of the subsequent surface engaging tool. By the above rough fingertip operation, it is possible to complete the stable and reliable fixing of the overlapping portion of the two base materials .

Next, a method for automatically determining the position of the surface engaging tool will be described. Confirming the position of the pair of surface engaging tools on the substrate with a finger is the first step in determining the position of the surface fastener. This is because the substrate formed by punching a plastic thin plate is superior in rigidity compared to a substrate such as cloth, and is easier to recognize with a fingertip than a button or the like. Become.
Due to this feature, in the case where the two base materials are overlapped and fixed, there is a merit of performing the engagement of the surface engaging tool first in the attachment in which the surface engaging tool and the button are mixed. That is, it is easier to confirm the position of the button as a second position by confirming the position of the button in the vicinity than fixing by attaching only the conventional button.

As a next step, even if rough insertion work without visual confirmation of the insertion position of the protrusion is performed, that is, even if the tip of the protrusion is inserted near the top of the upper edge or the lower edge , the plastic Due to the bending of the thin substrate, the slipping property causes slipping along the slope of the hole cut , leading to the maximum length of the hole up to the base of the protrusion. As the tip of the protrusion is inserted deeply into the base of the protrusion, the protrusion is inserted up to the maximum length of the hole. No further insertion is possible, and the bases of the protrusions are fixed by fitting with the notches at both ends of the hole. Thus, the direction of the projecting portion to be tilted and rotated is automatically and accurately defined. Of course the longer the maximum length of the hole, the accuracy of the position determination function of the surface engaging member is improved. Further, when the number of fitting points is increased by arranging two holes on the side, the accuracy of the superposition position of the surface engaging tool is increased .

There are two methods for attaching the surface engaging tool to the base material: the actual item matching type and the pattern type. The former aligns the position of the hook-and-loop fastener engaged at the position on the base material to be attached . When the protrusion is inserted deepest into the hole and the convex locking piece is rotated on the concave locking piece to perform polymerization, the two surface fasteners are aligned with each other on the substrate. If the fastener is placed and fixed, the position of the hook-and-loop fastener, which is the engagement means fixed to the base material by rotation / polymerization after insertion, will be aligned, and the positional relationship of the overlapping of the base material will match become.

In the latter case, if the above-described operation is completed in advance and the positional relationship in which the positions of both engaging tools are determined on the base material is copied onto the pattern paper, repeated attachment under the same position condition becomes possible.
When using a surface engaging tool in a state where the surface fasteners are firmly engaged with each other in the actual alignment position, there is a possibility that the position may be shifted at the time of peeling. In order to temporarily reduce the area, the surface fastener is partially sealed with a cellophane tape or the like.

In addition to this, it is possible to design a shape that allows fitting of holes and protrusions. If the shape of the top edge of the hole (4) in Fig. 1 is designed to match the shape of the tip of the insertion protrusion (8), the protrusion is not inserted to the depth that reaches the maximum length of the hole. A fitting state can also be obtained by partial insertion up to the middle of. In this case, the protruding portion at the time of insertion is inserted on the hole portion or slightly laid on the periphery and inclined. If the locking pieces are tilted and engaged with each other while maintaining the oblique fitting state, the thickness of the substrates contributes, and the cut ends support each other so that the protrusions of the convex locking pieces are supported. When rotating in the hole and overlapping the concave locking piece, there is almost no deviation in the positional relationship of the surface engaging means. For this purpose, it is preferable to provide a slip prevention protrusion in the hole part as an auxiliary, or to provide an overlapping part that performs the same function in the protrusion part.

It is necessary to devise so that the position of the hook-and-loop fastener can be determined stably without any trouble. When the protrusion of the convex locking piece is raised and the hole of the concave locking piece is inserted like a fingertip, the vertical angle of the protrusion is insufficient with respect to the hook-and-loop fastener. If there is an excessive operation of the protruding portion that is too much laid down, there is a risk that partial engagement may occur due to an undesirable positional relationship between the edges of the hook-and-loop fasteners. It is necessary to prevent this kind of unexpected engagement from occurring when the position is determined by fitting.

As a countermeasure, a zone where the hook-and-loop fastener does not function is provided at a position in contact with the lower edge of the hole. Simply placing the belt-shaped hook-and-loop fastener on a thin plastic plate is to set it at a distance from the fitting hole or protrusion. As a method for keeping the distance between the hole and the hook-and-loop fastener at least about 3 mm at the periphery of the hole, when punching the plastic thin plate with the hook-and-loop fastener with a wooden mold using a punching wooden mold, it was added to the wooden mold The surface fastener around the hole is punched at a distance from the hole with a half cutting blade.

As another method, there is a method in which the engagement element is destroyed by a heat melting process in a portion where the occurrence of the undesirable engagement is a concern . This heat melting treatment can also be performed before punching out the surface fastener in accordance with the shape of the substrate or as a finishing post-treatment. By adopting this method, even when the hook-and-loop fastener exists close to the hole, a portion that cannot be engaged can be formed on the periphery of the hole of the hook-and-loop fastener .

  Next, examples of clothes plackets will be described with reference to FIGS. As shown in FIG. 7, in the overlapping portion of the end portion of the fabric B and the end portion of the fabric A, the hole of the concave locking piece is fixed to the fabric B toward the fabric end as shown in FIG. Secure the hook-and-loop fastener toward the fabric edge. As shown in FIG. 7, the first engaging operation is as follows. First, the hook and loop finger of the convex locking piece in A on the upper side of the overlapping portion is sandwiched between the thumb and forefinger, and the other finger is pressed against the overlapping portion of the B fabric. .

  FIG. 8 is a diagram in which the operation of engaging the hook-and-loop fasteners of the opposing locking pieces is continued and engaged by operating with fingers sandwiching the hook-and-loop fastener portions of the convex locking pieces. By operating with a finger sandwiching the hook-and-loop fastener portion of the convex locking piece, the protrusion on the fingertip is guided to the hole of the concave locking piece with the sense of a fingertip. Whether or not the protrusion is inserted to the maximum length while sliding in the hole can be detected by a change in the contact condition between the slightly hard substrates. Also, if a protrusion enters the hole in this part straight, it can be recognized by the edge of the hole and the base of the protrusion.

  FIG. 9 is a diagram in which the engagement is deeply advanced, the convex locking piece is gradually tilted, and the engaging means is pressed until it is completely parallel. Rotational slipping of the protrusion occurs in the hole, and both the locking pieces automatically overlap in a parallel state. If the shapes of the upper end arc of the hole and the tip end arc of the projection match, the initial engagement state is released at the stage of pressing both locking pieces, and both engage in a parallel state. If used, the engagement of the two base materials can be completed with one hand holding the hook-and-loop fastener portion.

A method of fixing the release paper-attached surface engaging tool to a substrate such as a fabric will be described. The hole portion of the concave locking piece and the protrusion portion of the convex locking piece are fitted in advance to engage the both locking pieces in a normal positional relationship, and these are overlapped portions of the two base materials. Place inside. First, the former rear release paper is removed and fixed to the inside of the substrate. Next, the latter release paper is removed and the overlapping base material is pressed and fixed. Normally, the attachment of the surface engaging tool is completed by this superposition / pressing operation. If much higher fixation strength of the adhesive of the engaging member back from the engagement strength of the surface engaging member can withstand engagement and separation of stable repeatedly.

Sewing method according to the yarn is another attachment method and this is fixed work surface engaging member after the positioning on the substrate surface engaging member becomes somewhat difficult. In order to prevent a positional shift at the time of attachment to the base material, as a method of indicating the position of the edge of the substrate on the base material, mark-like temporary sewing, marking or the like indicating the attachment position by the thread of conspicuous color is required. In this case, a small amount of adhesive tape is used as an auxiliary. When the sewing of both the locking pieces to the base material is completed, the mark thread is removed. Another method is to mark the mounting position of the locking piece in advance using a pattern.
The high-frequency welding method is excellent for simply attaching the surface engaging tool after the positioning of the surface engaging member at the overlapping portion of the base material while keeping the mutual positional deviation .

When the surface engaging tool is fixed to the base material, it is important to adjust the attachment positions of the both locking pieces to the base material. It is better to consider the handling of the locking piece at the fingertip ergonomically . In the case of clothes , the fingertips are arranged at an angle that allows easy movement with respect to the end of the placket that is positioned vertically from the bottom of the chin. If the locking piece is arranged by slightly twisting and tilting according to the dominant hand used for position confirmation and engagement, the engagement becomes easy and the clothes can be easily attached and detached.

  Further, when a button having a shape that can be easily sensed by touch, such as a spherical button, is attached so that this detaching operation is facilitated, the engagement of the surface engaging tool becomes quicker. For locking pieces that are under the base material and are difficult to visually check from the surface of the base material, install them so that they are located at the front center of the locking piece. Faster initial movement.

  FIG. 4 shows a variation of the hole shape of the locking piece for obtaining the fitting for determining the automatic position. Moreover, the variation of the protrusion shape of a convex locking piece is shown in FIG. In the above description, the description has been made on the basis that the same circular arc is provided on both locking pieces. Here, various shapes that become the fitting shapes of the holes and protrusions that break this same relationship are shown.

The shape a in FIG. 4 is a hole shape provided with a protrusion for holding the protruding portion at the upper edge of the hole and bent so that it easily bends and enters when there is a protrusion. The b-shape is an oblong shape in which the fitting with the protrusion is slightly loose. The c shape is a substantially semicircular shape formed by a substantially straight line with an arc, and the d shape is a rhombus formed by a straight line. The e shape is a long ellipse with a protrusion that prevents the protrusion from coming off the hole when the protrusion is rotationally polymerized.

Another function is similar to that of FIG. 4c, and there is a hole shape of FIG. 11b. This is a semicircular shape in which the upper edge of the hole is a straight line and the lower edge of the hook-and-loop fastener side is an arc. If the contour of the concave locking piece in the shape of this hole is designed to be a straight line parallel to the hole, the overall shape of this board will be a slightly narrow rectangle, and the contour that forms the hole will be a thin bar as shown in the figure. become. When the width of this rod-shaped portion is 2-5 mm and both locking pieces are rotationally fitted to engage the surface fasteners, the protrusions of the convex locking pieces overlap with the rod-shaped portions of the concave locking pieces and push up. With this action, if the substrate is made of a soft material such as vinyl chloride resin, the portion is easily bent. This state is shown in FIG. 11e, and this deformation improves the inclined engagement state between the engaging surface fasteners caused by the repulsion of the rod-shaped portion.

In the case of this semicircular hole shape, the substrate width can be designed to be narrower by 6 mm to 8 mm than in the case of a substantially symmetrical lip-shaped hole. Although this eases the fit somewhat, the width is reduced to about 22 mm to 25 mm, resulting in a design advantage. In this case, the appropriate substrate length is 65 mm to 70 mm.
As long as the hole shape is a combination of a sufficiently divergent opening and a corresponding protrusion fixed at the base, a position confirmation function is generated by rotation and superposition, and thus the hole shape can be designed to an arbitrary shape.

FIG. 5 shows some protrusion shapes of the convex locking pieces. The protrusions may be any shape that can position determined by fitting deeply inserted into the hole. It is not always necessary to match the shape of the tip of the protrusion and the top of the hole. In the case of a large shape having a portion where the tip of the protrusion overlaps with the upper edge of the tip of the hole, the engagement between the hole and the protrusion is not automatically released after the rotation of the engagement pieces. Any shape may be used as long as the fitting occurs at a certain stage of insertion and the root of the protrusion can move to the maximum length of the hole thereafter. That is, it is sufficient that at least one of the holes formed by the upper edge (4) and the lower edge extends to the intersection of the upper edge (4) and the lower edge. And it is preferable that the upper edge part (9) is widening also about the whole shape of the projection part fitted in this. Even if the upper edge of the hole is an arc, it is possible to adopt a shape in which a substantially straight portion is provided at the tip of the protrusion (a and c in the figure ).

Explanation regarding claim 5 will be given. When the fitting means portion is designed so that an overlapping portion is generated due to the relationship between the hole shape and the shape of the protrusion, the engagement of the hook-and-loop fastener starts when both the locking pieces are tilted and brought into a parallel overlapping relationship after fitting. When pressed further in this state until they become completely parallel, engagement occurs with the hook-and-loop fastener portion while maintaining the fitting between the hole portion and the protruding portion. The degree of engagement of the surface engaging tool is enhanced by the fitting and engagement at these two locations. When the overlapping portion in the relationship between the hole shape and the protrusion shape is provided as a minute protrusion, the minute protrusion is shown in the hole portion in FIG. The engagement at this hole is easily released by twisting this part with the fingertips due to the characteristics of the plastic thin plate.

Further, this overlap is slightly larger in the case where the protrusion described in the previous paragraph has a larger shape having a portion that overlaps the upper edge of the tip of the hole. In this case, the engagement can be released by peeling the surface fasteners of the engaging means. Therefore, the fit state is The design of the surface engaging tool that makes use of the characteristics that cannot be released is effective. The drawback is that the hook-and-loop fastener portion that is superposed by the repulsion between the substrates of the fitting means tends to be inclined, and technical considerations are necessary to eliminate this.

Up to this point, there has been a fitting relationship with one hole and one protrusion. Hereafter, an example of providing a plurality of these on both locking pieces will be shown. FIG. 10 shows a concave locking piece in which holes are arranged in two stages in the vertical direction and a convex locking piece in which one protrusion is inserted into a hole selected from the two-stage holes . In this case, two types of engagement positions can be selected, and the tightness of the surface engagement tool can be adjusted in fitting clothes and the like. It is advisable to prepare two types of hole edge shapes so that a mistake in the selection of the hole before position confirmation by fitting can be detected by the operation of the fingertip. Set so large with respect to the vertical direction size of the surface fastener of the convex form locking pieces in this combination used.

Act a position determination error due to the erroneous selection, even when providing a plurality of holes in transverse relation shown below, advance Chigae the size of the protrusion hole, unreasonable in easily fingertips mistakes insertion position It should be possible to detect insertion. In this case, the hook-and-loop fastener is horizontally long, and automatic position determination is more reliable. Also, the engagement strength is increased. This method of preventing a position determination error due to an erroneous selection operation also exhibits the same effect when a large number of small locking pieces each having one hole and one protrusion are used.

FIG. 11 shows an example in which two holes are arranged in the horizontal direction. In this case, two protrusions of the convex locking piece are also arranged side by side. In order not to excessively increase the size of the entire locking piece, two holes and protrusions are arranged next to each other with a distance of 4 mm to 10 mm. The shape of the hole (a) is roughly the lip shape of the target shape, and the hole on the opposite side of the hook-and-loop fastener has a function to prevent detachment during rotation / polymerization operation. A small protrusion is provided for loading the tip protrusion of the stop piece. The hole shape of the surface engagement tool in FIGS. B, c, and d is a semicircular shape, and the rod-like portion between the outer peripheral edge of the straight portion of the semicircular hole plays a role of preventing the disengagement during the fitting operation. This rod-like portion introduces the tip protrusion of the convex locking piece to prevent disengagement during fitting.

Further, in this figure, the hook-and-loop fastener is fixed so as to cover the hole portion. However, the hook-and-loop fastener portion to be covered is cut out so that the fitting in the hole portion is not hindered. For this purpose, this portion of the blade is added to the punched wooden blade. Even if the sewing thread of the locking piece reaches this part, the thread can be cut and fitted well by inserting an additional cutting tool into the punched wooden mold.

By arranging the holes and protrusions in this way, when searching for the fitting position using the slipperiness of plastics to fit the protrusions into the holes, this work is performed while keeping them parallel to each other. The advantage is that it can be performed stably and easily. In order to make the most of this advantage, a shape in which a certain amount of straight part is provided at the base edge of the protrusion is preferable. This is because the function of correcting the tilt in the fitting position search is exhibited.

The type which provided the seam allowance (13) in the hook_and_loop | surface fastener so that the operation | work attached to clothing with the surface sewing tool shown in FIG. 11 by hand-sewing or a household general sewing machine is shown. (Refer to b, c, d in FIG. 11) By providing this seam allowance, the hook-and-loop fastener and the base material are joined to each other by sewing using a thread and a needle of a household sewing machine only (see FIG. 11c). ). Of course, it is possible to sew at this seam allowance using an industrial sewing machine. Also in this case, the edge of the substrate can be covered widely, and the merit of substantial increase in the engagement area arises.

In order to increase the degree of adhesion between the base material and the plastic substrate by sewing by hand sewing, a sewing hole (14) for connecting and sewing the surface fastener and the base material to the plastic substrate in the area of the surface fastener is the substrate. Depending on the size, 3 to 5 may be provided. In this hole area This is an adhering effect by binding the base materials with a thread across the substrate. This hole has no problem even when it is fixed by sewing.

The size of the hole is preferably a large hole so that the position of the hole can be specified by the touch of the fingertip even if it is covered with a hook-and-loop fastener, the needle threading may be obliquely threaded, and the rough position can be confirmed. Actually, a hole having a diameter of about 5 mm to 10 mm or a long hole corresponding thereto is suitable. The position of the hole in the substrate is provided at the end of the hook-and-loop fastener near the protrusion or the hole so as to enhance the fixing effect. This position is determined by the material and thickness of the plastic sheet from which the substrate is punched. This is because it is necessary to consider the ease of cracking during impact punching. FIG. 11 e shows a schematic diagram of the state where the sewing tool is used to attach the engagement tool to the garment using the seam allowance.

In FIG. f, the substrate shape is a composite type of a concave locking piece and a convex locking piece, which can be used as a single locking piece. That is, it has a special shape that holds the protrusion and the hole in one substrate. This figure does not have any seam allowance, but can be attached to both ends. It is appropriate to sew the dual-purpose type surface locker to the base material with an industrial sewing machine. The feature of this surface locking tool is that it requires only one type of wood management and one type of product management, which is advantageous in terms of cost.

Here, the details of the basic material used for manufacturing the small surface engaging tool will be described. Indispensable materials are hook-and-loop fasteners and plastic sheets. These are fixed at predetermined positions in the production process to obtain a laminate material for punching.
A hook-and-loop engaging element is formed in a base shape by a knitting weaving method as a cheap popular type of hook-and-loop fastener, and two types of hook-and-loop fasteners are used facing each other . Other than this, one using one type of engaging element represented by a mushroom-like shape by another manufacturing method , or one having hooks and loops mixed on the same surface fastener surface can be used. In addition to these, as a sound reduction type, a type has been developed that suppresses the buzzing sound that occurs when two surface fasteners are peeled off.

The present invention is not restricted by the type of the hook-and-loop fastener, and can be used as long as it can be fixed to the substrate. Moreover, although it is convenient to use as a similar material, an adhesive material such as a double-sided adhesive tape can also be used as a fixing material as a substitute for a hook-and-loop fastener.

In the case of the punching method, a plastic thin plate is usually used as the material for the substrate . Adhesive double-sided tape can be fixed to the back surface of a substrate made by punching out this thin plate, and an easy-to-sewing characteristic that allows a surface fastener and a substrate to be overlapped and penetrated with a needle of an industrial sewing machine is obtained. In addition to this material, a sheet material that meets these conditions can be used. Good sewing machine needles are essential, and there are limits to thickness and sheet hardness. If it is a general-purpose resin, a relatively inexpensive sheet material such as PP, PVDC, or PET is suitable. Although different depending on the resin, a sheet having a punching suitability of a thickness of 0.2 mm to 2 mm is usually used. A preferred range is 0.4 mm to 0.8 mm. If the surface fastener and the substrate are integrated by the adhesive fixing method, a slightly thicker one can be used.

In addition, a foamed PP sheet as a low foamed sheet is preferable for obtaining a thickness that makes it easy to obtain a feeling during fitting. As a special sheet, a resin-treated paperboard or a laminate sheet of various films can be used. If decoration is more important than cost, a glossy metal sheet, a stone plate, and the like can be used as materials if they have excellent rigidity and slipperiness when engaged. This includes a wire that can be bent to form the outline of the substrate.

In addition to the sheet material, a substrate having a predetermined shape can also be obtained by injection molding. In the case of this production method, molding is performed using a general-purpose resin. In the case of this manufacturing method, the thickness of the substrate can be partially changed, and this is suitable for partial adjustment of rigidity. And the tip of the convex locking piece during sewing In the mold design, it is possible to easily obtain a shape in which the vicinity of the protruding portion of the needle is slightly bent toward the needle driving side due to the penetration impact of the sewing machine needle and is inclined in the shape of a “he”. The effect of this shape is to reduce repulsion when the substrates are mated. Even with a small surface engaging tool, the facing state of the surface fasteners approaches parallel, and the appearance when a pair of surface engaging tools is attached to the garment is improved.

For the manufacturing method of small surface engaging member to secure the surface engaging member with an adhesive material to a substrate is described. An example in which six rectangular small surface engaging tools shown in FIG. 12 are punched out from a laminated continuous sheet will be described. The surface engaging tool is punched out with the adhesive material with release paper attached. The product is an explanation for finishing with release paper. A layout drawing is provided in which trim margin is provided around the locking piece to which the six surface fasteners are fixed, and a two-cutter arrangement is made as shown in FIG. Punching is performed with a die that combines a concave locking piece and a convex locking piece. When selling as a sheet with six pieces instead of selling as a rose product, it is possible to make a punched sheet that is easy to handle by making a punched wooden shape that can be connected to the punched locking piece.

In the manufacturing process, as shown in FIG. 13, various apparatuses are arranged so that the continuous sheet can be manufactured. In order to manufacture the small surface engaging device, a general process of laminating and punching a sheet can be applied to a continuous process or a dividing process. In the uppermost stream, a roll ( 15 ) of a plastic thin plate is put on a stand, and the thin plate of the substrate is fed out. Next, the tape is drawn out from a roll ( 16 ) of a double-sided adhesive tape for attaching an adhesive for fixing the small surface fastener to the base material, and laminated on a sheet of plastic thin plate through a pressure roll. Next, a tape with a narrow surface fastener is unwound from the roll ( 17 ) of the surface fastener and is pressure-bonded to the previous laminate sheet. This hook-and-loop fastener is provided with a release paper, which is peeled off and transferred to the laminate sheet while being wound up.

Instead of using a double-sided pressure-sensitive adhesive tape as an integrated material of the hook-and-loop fastener and the substrate, it is also possible to incorporate an apparatus for applying and drying the pressure-sensitive adhesive material into the process. It is also possible to install an industrial sewing machine in the line and directly fix the hook-and-loop fastener to the plastic sheet by sewing. An industrial sewing machine is fixed with a sewing thread in the sheet flow direction with a hook-and-loop fastener, and is fixed to the upper and lower ends of the hook-and-loop fastener of the finished product with two threads (Fig. 11d) or any one thread. .

  The sewing method that is suitable for small-scale production is to fix the surface zipper to the position where the hook-and-loop fastener fastener is marked on a fixed-size oval plastic sheet, and then sew it continuously from end to end with a table type industrial sewing machine. A batch punching method is suitable. The surface engaging tool produced in this way is shown in FIG. In the surface engaging tool shown in FIG. 11d by this method, the protrusion at the tip is slightly bent toward the needle driving side by the penetrating impact of the sewing needle, and the effect of inclining in the shape of “he” is obtained. .

The sheet laminated on the three layers is controlled through a pressure-bonding / feeding roll ( 18 ) and a feed amount and position detector ( 19 ), and is supplied to a punching machine ( 20 ). In this process diagram, the punching machine is a die press that performs intermittent punching. The wooden mold attached to the die press is attached in accordance with the layout drawing (see FIG. 12) by punching the blades into various shapes shown in FIG. 1 to FIG. 11 (excluding FIG. 6). This presupposes that a rigid surface engaging tool is sewn to the base material using an industrial sewing machine.

In order to punch out so that it can be attached to the base material by hand-sewing, it is punched in a line or off-line into a shape in which a seam allowance is provided for the hook-and-loop fastener. For this purpose, the substrates arranged in the wooden pattern are spaced from each other, and a seam allowance is provided therebetween. The boards are arranged side by side so that the sewing allowance of this one engagement tool is 2 mm to 5 mm, and a wooden pattern is produced with the removed dregs portion being minimized. A punching margin is formed simultaneously on both sides or three sides of the substrate in the punching process of the surface engaging tool. This makes it easier to manage quality.

For this purpose, the height of the wooden cutting blade is designed to be partially different. In the seam allowance (13), a half-cutting blade is used in which the cutting blade penetrates only the substrate shape portion and the blade does not enter the hook-and-loop fastener portion on the back surface. The contour cutting of the seam allowance is made into a combined wood pattern using a through blade that is fully cut.

Next, the punched sheet enters a trimming device ( 21 ) that separates the residue from the product. A wooden mold incorporating a pressing rubber and a protruding jig is attached to this device.
Next, the punched-out locking piece is pushed out at the same time as the trimming, is struck down into the bucket, and accumulates in the product bucket ( 22 ). The remaining part other than the product is wound on a winding roll (23) . Instead of this winding, it can also be bundled into a bucket as a small piece while cutting with a vertical rotary blade.

Instead of the intermittent flat punching method shown here, it is also possible to punch using a mold with a rotary continuous device. In addition, the trimming device can also be performed by a pin-rotating type of depression and pop-up method. If there is a condition for mass production as a standard product, continuous rotary equipment with high production efficiency can be introduced. If it is a low speed line, a laser cutting device or a water jet cutting device can be introduced instead of the punching device.

  A manufacturing method different from the substrate manufacturing by punching the plastic thin plate can also be adopted. This is a resin injection molding method. This manufacturing method has the advantage that in the mold design of a molded product, the thickness can be partially reduced so that the needle can be easily passed, and the contour can be easily rounded so that the finger can be easily touched. . At the time of injection molding of the shape of the substrate, the hook-and-loop fastener can be attached simultaneously by the in-mold method.

  The above explanation is about fixing a surface fastener to a substrate having excellent rigidity and providing a fitting hole or protrusion on a part of this substrate, but an engagement function as an alternative to this surface fastener. It is possible to use a male or female snap hook made of metal or resin. The hook is generally used in a size smaller than that of a normal button, and has a size that is difficult to handle with a fingertip and is difficult to position. Because of this drawback, its use is limited and not widespread.

However, the finish on the surface engaging member with fitting means of the present invention, these disadvantages are eliminated. To form the hook group into a plastic substrate (not shown), three hooks are fixed to the substrate in a zigzag manner . This fitting method hook formula surface engaging Gogu incorporating may conveniently reliably position determination of male and female hooks, after this localization, together multiple hooks, or by using a palm simultaneously in order, positional deviation Can be done without worrying . The hook can be fixed to the substrate by fusion bonding or in-mold integral molding.

The present invention, by leaving fixed a small piece of stiff two types of locking piece which is fixed to the surface engaging means, typified by a surface fastener to a substrate a soft cloth or the like, the rough engaging member with the fingertip sensation The position can be confirmed, and the correct position is determined by fitting the projection provided on the convex engagement piece used opposite to the notch provided on a part of the concave engagement piece. By pressing the fasteners to each other, the locking pieces can be engaged with each other with one hand without worrying about misalignment by blind touch.

Disabled elderly hand by putting this function, or the desorption of physically handicapped clothes easily. In addition, it is possible to manufacture a new garment that can be performed without anxiety about misalignment.
In addition, by using this engagement tool with a hook-and-loop fastener, it is possible to increase options other than buttons and zippers that are generally used in the design of clothes that require fashionability.

The present invention can also be used for industrial sheet materials other than fabrics. One of them is linen sanitary cloth used for seats on bullet trains. It can also be used for household seats, an example of which is covers for bedding. Even in these attachments, the position can be easily confirmed, quick work can be performed, and the appearance can be improved.

  The present invention provides a compact surface that can be securely and easily aligned with the sensation of a fingertip at an overlapped portion attached to two base materials such as cloths of clothes and the like. The present invention relates to a fastener, an engagement tool comprising a concave engagement piece provided with a surface fastener portion and a cut portion on a plastic substrate, and a convex engagement piece provided with a surface fastener portion and a projection on the plastic substrate, and It relates to a manufacturing method.

  As a conventional means for joining at the overlapping portion of two base materials, there is a normal button system composed of a button and a button hole as an easily removable means. This method is said to have been developed in England in the middle of the 18th century. There is a relatively loose button string system that engages a button-like protrusion with a narrow string somewhat earlier than that. This is a technique that was applied to samurai costumes in Japan in the early 18th century. This was mainly used for the longitudinal engagement with heavy loads because the connection was loose.

  After these coupling means were developed, ultra-small metal snap hooks were put into practical use. However, there was difficulty in positioning and it was not popular. Since then, surface fasteners have been developed up to the 20th century, and have been used under the conditions that can be used by fixing a slightly larger size to two substrates with relatively rough positioning.

  In Japan, as a coupling means developed in recent years, there is a “Kohaze” method, which is a hooking method using a combination of a metal nail shape piece and a thick thread. This is currently only used to secure the buttocks of the tabi. This limited use is due to the difficulty of work and uncertain positioning. Specifically, in the overlapped portion of the tabi, the heel part fabric is fixed in such a way that a small piece of metal sewed on the upper fabric end is held in place on the lower fabric end, but both are small. It is a member, it is difficult to confirm the position by blind touch, this overlap part must be pressed sufficiently, and even if the engagement between both is not tight, there is a possibility that it will come off during use There are some.

  A fastener that has the most room for development is a hook-and-loop fastener. Although this material is unsatisfactory, it has a track record of being attached to clothes. One of the scenes in which this hook-and-loop fastener is used is the engagement of a short moving distance between hook-and-loop fasteners and the upper part of the chest where uncertainty of position determination does not become apparent. It is used where the displacement of engagement is not noticeable. These cases are relatively small pieces. Another scene is the engagement of the lid of the bag that opens widely, the pillow cover, etc., and even if there is a shift in this engagement, it is not so noticeable. The hook-and-loop fastener that is fixed to the overlapping portion of the two base materials is often large in size, with one side being several centimeters or more, even when one hook-and-loop fastener is small.

  There is a situation in which it is difficult to use a hook-and-loop fastener in a clothing or the like where the feeling when worn is important and the appearance is worrisome, causing a displacement of the engagement. In addition, there has been a problem of an annoying sound of merriness at the time of peeling, which has existed as a problem when this hook-and-loop fastener is used for clothes and the like. However, this problem has been improved by manufacturers and released as a sound-reducing surface fastener, which has been resolved. The development of a simple engagement technique by pressing this new material has attracted attention again.

  The only method disclosed in U.S. Patents is to engage the bases with hook-and-loop fasteners after positioning. According to this method, the position of the tip is determined using the relationship between the insertion hole provided at the end of the belt-like substrate and the insertion projection, and then the hook-and-loop fastener attached to the adjacent portion is pressed to detach the substrates. Can be easily fixed. This method has problems in that it is an invention aiming at the engagement between the substrates and that it is difficult to insert and fix the tips of the substrates. In the disclosed method, it is necessary to complete the insertion and fixation while visually confirming the positional relationship between the hole and the protrusion. Looking at the shape of the disclosed holes and protrusions, a semicircular portion is provided in the center of the groove-shaped hole, and a part of the groove is widened. This shape has no effect of facilitating the insertion and fixing of the bent projections. It is judged that it is for facilitating removal of a thin groove in a punching process with ruled lines.

After the present invention, there has not been a universal design engagement means that combines the certainty of connection, the ease of operation, and the ease of positioning in the world.
A universal design that has become a global trend in recent years, but wants to make it easier to combine the placket of clothes for people with disabilities in the fingertips as the number of elderly people increases (including people with disabilities including the visually impaired) Demands arise. Various developments have been made based on this requirement.
In such a stagnation of technical development, attention has been paid to a zipper that is expensive in processing cost. However, it has been difficult to insert the chuck fixing portion at the lower end portion of the placket, and has not led to a fundamental solution. Recently, news of the developed product was released, which was released in September 2010 as a cardigan fitted with new clothing fastening means from Aeon. Although this is a conventional button system, the buttonholes are arranged obliquely to improve the fastening workability. Thus, there is a demand for the development of universal design coupling means.

  US Pat. No. 3,873,051

The present invention has been made to solve the problems of the prior art as described above, and reliably superposes the base material where the positional relationship cannot be accurately confirmed visually such as a placket of clothes, and An object of the present invention is to provide a small hook-and-loop fastener with a position fixing function by fitting that can be easily performed. Specifically, a surface fastener is fastened as an engaging means to a small concave locking piece punched out of a plastic thin board and a convex locking piece, and a hole or protrusion fitting means is separately provided in the vicinity of this. It is formed so that the position can be determined by insertion by rough blind touch. Provided is a small engagement tool with a hook-and-loop fastener that can accurately and easily attach and detach two substrates by pressing both locking pieces in parallel while maintaining this mating state, and a method for manufacturing the same. It is.
Aging societies are advancing in developed countries, including Japan, and emerging countries, and in Japan, the proportion of elderly people over the age of 65 has exceeded 23%. In such a society, people who have difficulty in fine-fingered fingertips, and clothing used by people with disabilities, such as the visually impaired, can use a cheap and simple operation instead of buttons and zippers to set the base at the correct position. There is an urgent need to develop hook-and-loop fastener applications that allow engagement of materials. There is a social need especially in the field of nursing care.

  As of 2010, attaching a hook-and-loop fastener to a garment is being performed at homes and elderly care facilities. A pair of hook-and-loop fasteners that have been punched into a round shape with a diameter of 22 mm is set and sold as a “round magic”. When this is attached to clothes, the position confirmation of both hook-and-loop fasteners is insufficient for fingertip confirmation. In general, a decorative button is attached on the outer surface of the clothes as a mark so that the attachment position of the soft hook-and-loop fastener can be confirmed with a fingertip.

The present invention solves the above-described problems, and is a surface engaging tool with an engagement position determination function. Here, the case where a hook-and-loop fastener is used as the engaging means will be mainly described. The means of the U.S. patent disclosed as a technique relating to the alignment of the surface engaging tool is accurate as in the conventional button type when used for clothes, as mentioned above. The position confirmation by visual observation is a prerequisite. In the case of clothes, the operation is performed directly under the eyes, and it is difficult to accurately confirm this positional relationship. In addition, there is a restriction that drilling in the substrate is practically impossible.

A pair of small surfaces according to claim 1, wherein the surface locking pieces are used adjacent to each other, and are arranged with different sizes or shapes of adjacent notch portions or protrusion portions. The present invention relates to an engagement tool.

According to an eleventh aspect of the present invention, there is provided a concave locking piece including a surface engaging means and a notch portion, and a convex locking including a surface engaging means and a protrusion. A pair of small surface engaging tools that are formed of a piece and disposed on the base material, the notch portion of the concave locking piece being arranged toward the end portion of the base material on the lower side, and The present invention relates to a pair of small surface engaging tools characterized in that the engaging means of the convex locking pieces are arranged toward the end of the base material on the upper side.

A hook-and-loop fastener is fixed to the plastic substrate, and a concave locking piece having a notch portion having a shape capable of automatically determining the position in the vicinity thereof is formed. This incision is usually a lip-shaped punched hole in which upper and lower arcs are connected symmetrically. The convex locking piece used in opposition to the concave locking piece is obtained by fixing a surface fastener having a function of engaging with the surface fastener to a plastic substrate and inserting the hole into a portion adjacent to the surface fastener. It is composed of a convex locking piece having a projection of a shape that automatically fits.
These concave locking pieces and convex locking pieces are superposed and fixed to the ends of the two base materials to be engaged with each other, and the base materials in the expanded state are inserted at rough mating portions. By the automatic position determination according to the above, the engagement that does not cause a shift by the subsequent pressing is completed.
A hook-and-loop fastener is an excellent material that can be engaged with sufficient strength by simple pressing. However, once engaged, a considerable amount of force is required to release the engagement, so that the two fasteners can be reliably engaged with each other in a precise positional relationship by a single engagement operation. Must complete the match.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, typical embodiments of a small surface fastener with a position determining function according to the present invention will be described with reference to the drawings. 1 and 3 show a concave locking piece in which a hook-and-loop fastener according to the present invention is fixed to a plastic substrate with a double-sided adhesive tape and a notch hole is formed in the vicinity thereof. The notch used here includes a hole shape. The right figure of FIG. 1 is an example of the sewing pattern of the thread | yarn with the base material by an industrial sewing machine. FIG. 2 shows a convex locking piece provided with a hook-and-loop fastener that engages with the plastic substrate and a projection that can be fitted into the hole. The right figure is an example of a sewing pattern of a thread with a base material by an industrial sewing machine. FIG. 6 is a cross-sectional view of both locking pieces, showing that the substrate and the hook-and-loop fastener are laminated with an adhesive material. In order to manufacture the laminate in the shape of a locking piece, a hook-and-loop fastener is fixed to a thin plastic plate in a band shape, and this is punched out into a desired fitting shape or melted. This manufacturing method will be described later.

First, a detailed configuration of the locking piece will be described. The fixing of the substrate and the hook-and-loop fastener shown in FIG. 1 and FIG. 2 is usually made by a sewing method in which the hook-and-loop fastener fits on the substrate with a margin. This fixing method is classified into two types. The method shown in FIGS. 1 and 2 is to attach a surface fastener to a substrate in a label manner. Although it is the form which provided the space around the hook-and-loop fastener, there exists a form which the edge of punching and the edge of three sides of a hook-and-loop fastener become the same as another form. In the latter case, a belt-like continuous surface fastener is used for substrate molding. Both can be processed with adhesive and machined. As the engaging piece processing, it is easier to fix the surface fastener by the adhesive material processing. The disadvantage is that the sewing material is not suitable for sewing because the adhesive material gets entangled with the needle.
It is also possible to employ a method in which the surface fastener is fixed to the substrate at a part thereof (not shown). In this case, the hard part of the substrate and the soft part of the surface fastener are present in the locking piece. Even in this structure, the slipperiness and rigidity, which are the characteristics of the substrate material, can be used for fitting the hole and the protrusion, and can be adopted.

  Next, a method for fixing the formed locking piece and the base material will be described. There are three types of fixing. One of them is to sew both locking pieces, which are formed by punching, into the overlapped part of the placket of clothing with the thread of an industrial sewing machine. The second is to remove the double-sided tape release paper with strong adhesive material by the adhesive material method and fix the locking piece to the base material. The third is high frequency welding. This method is limited in the material of the base material that can be applied. In the case of the present invention, a fixing method using an adhesive material is appropriate. This method is general and will not be described.

The sewing method is a method often used when attaching a hook-and-loop fastener to clothing. First, the sewing method performed with the margin of the concave locking piece and the base material will be described. Basically, the substrate and the base material are fixed only around the surface fastener on the substrate. Not only does the surface fastener, which is the area where the peeling force is applied, stably adhere, but also sewing is performed on the tip area of the hole other than the blank part of the surface fastener, the movement of the fabric under the board during fitting is restricted. It will be. That is, the sagging of the fabric due to abutment of the protrusion to be inserted is less likely to occur. In order to exhibit the slipperiness of the cut surface of the hole in the plastic plate, it is desirable that the fabric on the back surface of the concave locking piece bend so that the protrusion can be easily inserted into the hole. The sewing shown in FIG. 1 shows a sewing method performed by an intermediate concave locking piece and a base material.
In a relatively soft pajamas fabric or a backpack, if the tip of the protrusion is protruded around the hole and inserted into a normal hole, the cloth tends to bend. However, a thick fabric such as a winter clothes is less likely to cause this deflection, and in this case, in order to facilitate the insertion of the protrusion, a cut is effective in the fabric under the hole.

  Next, a sewing method performed between the convex locking piece and the base material will be described. FIG. 2 shows an example of sewing convex locking pieces. Although related to the description of claim 7, it is necessary to make this portion free so that the protrusion of the locking piece can be fitted with the hole in a state of being held and held by the fingertip. Sewing is limited to the area around the hook-and-loop fastener so that the movement of this portion is not restricted by the sewing.

The shape of the locking piece will be described. The outer shape of the locking piece shown in FIGS. 1 and 2 is a square shape. And the four corners are chamfered. The advantage of the square shape is that it is easy to recognize the angle with respect to the end portion of the base material when the locking piece is attached to the base material. What is necessary is just to design so that the position of the both ends of a hole part and the base of a projection part may become parallel with respect to the cutting line at the side fastener side of a latching piece. If the corners are rounded as much as possible, the risk of the edges of the substrate damaging the fabric during washing can be reduced.
These contour shapes can be designed arbitrarily. A round shape and a rectangular shape are fundamental, and it can be said that it is preferable in terms of clothing design. Both the locking pieces in FIGS. 7 to 9 are shown as round shapes resembling buttons. These shapes and sizes vary depending on the base material to be used and the design concept such as engagement strength. This is because the round shape tends to float somewhat in use. These factors determine design conditions such as the area and shape of the hook-and-loop fastener, the number of attachments, and the like. When examining the attachment position of the engagement tool to the substrate, it is convenient for visual judgment if the cut end on the surface fastener side is straight.

  When the size of the engaging tool is determined, the convex locking piece that is an operation of gripping with the fingertip is first defined. When the size is easy to hold and the hook-and-loop fastener portion is square, an area of 15 mm × 10 mm square or more, preferably about 30 mm × 20 mm is required.

  Next, the shape and size of the hole of the concave locking piece will be described. First, as a basic shape, a description will be given of a hole for receiving insertion of a protrusion having a substantially arc-shaped tip. A substantially circular arc shape having a wide mouth as shown in FIG. This shape spreads toward the intersection of both arcs. Although this hole size depends on the size of the locking piece, the maximum length of the hole (the distance between the intersections of the upper edge and the lower edge) is about 10 mm to 40 mm, preferably 15 mm to 25 mm. Is about 5 mm to 30 mm, preferably 8 mm to 15 mm. This lip-shaped hole shape facilitates the insertion of the arcuate protrusion tip, and the position of the protrusion can be determined. In other words, the tip of the protrusion can be inserted without selecting the location of the hole.

  Next, an automatic method for determining the position of the hook-and-loop fastener will be described. Even if rough insertion work that does not specify the above insertion position is performed, that is, even if the tip of the protrusion is inserted near the top of the upper edge or lower edge of the hole, the hole of the hole is related to the characteristics of the plastic substrate. Slip occurs along the slope of the cut, leading to the maximum length of the hole to the base of the protrusion. As the tip of the protrusion is inserted deeply into the base of the protrusion, the protrusion is inserted up to the maximum length of the hole. No further insertion is possible, and the bases of the protrusions are fixed by fitting with the notches at both ends of the hole. Thereby, the direction of the protrusion part to insert is prescribed | regulated. Of course, as the maximum length of the hole becomes longer, the accuracy of the position determination function of the engaging tool is improved.

  In an engagement tool with improved accuracy of the position fix function, position the hook fasteners in advance and design them so that the two hook-and-loop fasteners match when inserted most deeply. In this case, the insertion of the hook-and-loop fastener, which is the engaging means, is always performed by this insertion.

  It is necessary to devise so that the position of the surface fastener can be stably determined. When the protrusion of the convex locking piece is raised and the hole of the concave locking piece is inserted like a fingertip, if the inclination of the protruding part in the gripping state is insufficient, the edge of the surface fasteners will be partially There is a risk of engagement. It is necessary to prevent unexpected engagement from occurring when the position is determined by fitting. As a countermeasure, the distance between the hole and the hook-and-loop fastener is set to 1 mm to 3 mm so that there is no hook-and-loop fastener at the position in contact with the lower edge of the hole.

  In addition to this, it is possible to design a shape that allows fitting of holes and protrusions. If the shape of the top edge of the hole (4) in Fig. 1 is designed to match the shape of the tip of the insertion protrusion (8), the protrusion is not inserted to the depth that reaches the maximum length of the hole. The mating state can also be obtained by inserting partway through. In this case, the protrusion at the time of insertion is slightly laid and inclined. If the locking pieces are tilted and engaged with each other while maintaining the oblique fitting state, the engagement means is hardly displaced.

  As another method for preventing the engagement at the end portions of the hook-and-loop fasteners between the two locking pieces before the position is determined, the engagement element is removed by heat melting processing at the time of fusing. It is a way to destroy. This heat melting treatment can be carried out independently as a post-treatment. If this method is taken, after fixing a hook-and-loop fastener to the whole locking piece, the part which cannot be engaged can be formed in a hook-and-loop fastener part.

  Next, examples of clothes plackets will be described with reference to FIGS. As shown in FIG. 7, in the overlapping portion of the end portion of the fabric B and the end portion of the fabric A, the hole of the concave locking piece is fixed to the fabric B toward the fabric end as shown in FIG. Secure the hook-and-loop fastener toward the fabric edge. As shown in FIG. 7, the first engaging operation is as follows. First, the hook and loop finger of the convex locking piece in A on the upper side of the overlapping portion is sandwiched between the thumb and forefinger, and the other finger is pressed against the overlapping portion of the B fabric. .

  FIG. 8 is a diagram in which the operation of engaging the hook-and-loop fasteners of the opposing locking pieces is continued and engaged by operating with fingers sandwiching the hook-and-loop fastener portions of the convex locking pieces. By operating with a finger sandwiching the hook-and-loop fastener portion of the convex locking piece, the protrusion on the fingertip is guided to the hole of the concave locking piece with the sense of a fingertip. Whether or not the protrusion is inserted to the maximum length while sliding in the hole can be detected by a change in the contact condition between the slightly hard substrates. Also, if a protrusion enters the hole in this part straight, it can be recognized by the edge of the hole and the base of the protrusion.

  FIG. 9 is a diagram in which the engagement is deeply advanced, the convex locking piece is gradually tilted, and the engaging means is pressed until it is completely parallel. Rotational slipping of the protrusion occurs in the hole, and both the locking pieces automatically overlap in a parallel state. If the shapes of the upper end arc of the hole and the tip end arc of the projection match, the initial engagement state is released at the stage of pressing both locking pieces, and both engage in a parallel state. If used, the engagement of the two base materials can be completed with one hand holding the hook-and-loop fastener portion.

A method for fixing the hook-and-loop fastener to the base material will be described. The concave locking piece and the convex locking piece are fitted in advance and engaged with each other in a normal positional relationship, and this is arranged inside the overlapping portion of the two base materials. First, the former rear release paper is removed and fixed to the inside of the substrate. Next, the latter release paper is removed and the overlapping base material is pressed and fixed. If the adhesion strength of the adhesive material on the back surface of the engagement tool is much higher than the engagement strength of the engagement tool, it is possible to stably withstand repeated engagement and separation.
The thread sewing method makes it somewhat difficult to secure the engagement tool after positioning the engagement tool on the substrate. Marked temporary sewing with a conspicuous thread is necessary. One method is to mark the mounting position in advance using a pattern paper. When the sewing of both the locking pieces to the base material is completed, the mark thread is removed.
The high-frequency welding method is excellent in easily performing the fixing after the positioning of the engaging tool at the overlapping portion of the base material.

  When the engaging tool is fixed to the base material, the direction of the engaging tool is important. You should consider the handling of the locking piece at your fingertip. In the case of clothes, it is slightly inclined at an angle that allows easy movement with respect to the end of the placket perpendicular to the body.

FIG. 4 shows a variation of the hole shape of the locking piece for obtaining the fitting for determining the automatic position. Moreover, the variation of the protrusion shape of a convex locking piece is shown in FIG. In the above description, the description has been made on the basis that the same circular arc is provided on both locking pieces. Here, various shapes that become the fitting shapes of the holes and protrusions that break this same relationship are shown.
FIG. 4 shows a shape (d) using a straight line as a part of a hole, a shape (a) using a curve protruding toward the center of the hole, or an ellipse shape (b) or an edge of a hole which is a slightly loose fit. Are shown so that the other party's protrusion can easily enter (see a). A combination of a sufficiently divergent opening and a corresponding protrusion fixed at the root provides a position confirmation function and can be designed in any hole shape.

  FIG. 5 shows some protrusion shapes of the convex locking pieces. If the position can be determined by fitting the protrusion deeply into the hole, it is not necessary to match the shape of the tip of the protrusion with the shape of the upper end of the hole. Any shape may be used as long as the fitting occurs at a certain stage of insertion and the root of the protrusion can move to the maximum length of the hole thereafter. Even if the upper edge of the hole is an arc, it is possible to adopt a shape in which a straight portion is provided at the tip of the protrusion (a, c).

  Explanation regarding claim 5 will be given. If the design is such that an overlapping portion is created by the relationship between the edge of the hole and the edge of the protrusion, the engaging pieces are brought into an interlocking state as the locking pieces are tilted to approach the parallel relationship. When it becomes more completely parallel in this state, engagement occurs between the hole portion and the hook-and-loop fastener portion. The engagement between the substrates is strengthened by the engagement at these two locations. The engagement at this hole is easily released by twisting this part with the fingertips due to the characteristics of the plastic thin plate. Therefore, it is possible to design a fitting that can determine the position based on this state.

  Up to this point, there has been a fitting relationship with one hole and one protrusion. Next, an example in which a plurality of these are provided on the locking piece is shown. FIG. 10 shows a concave locking piece in which holes are arranged in two stages in the vertical direction, and a convex locking piece in which one protrusion is inserted into a selected hole. In this case, two types of engagement positions can be selected, and the tightness of the engagement tool can be adjusted in fitting clothes or the like. It is advisable to use two types of hole edge shapes so that selection errors prior to position confirmation can be detected by fingertip operation. In this combination use, the size of the hook-and-loop fastener of the concave locking piece is set larger in the vertical direction.

FIG. 11 shows an example in which two holes are arranged in the horizontal direction. In this case, the protrusions of the convex locking pieces are also two. In this case as well, it is preferable to change the size of the hole in order to prevent an error in determining the position due to an erroneous selection operation so that an error in the insertion position can be easily detected by the fingertip. In this case, the hook-and-loop fastener is horizontally long, and automatic position determination is more reliable. Also, the engagement strength is increased.
This method of preventing a position determination error due to the erroneous selection operation also exhibits the same effect when a large number of locking pieces with one individual hole portion are used side by side.

Here, the details of the material used for manufacturing the small surface fastener will be described. Indispensable materials are hook-and-loop fasteners and plastic sheets. These are fixed in place to obtain a laminate material for punching.
A hook-and-loop fastener is a base-type hook and loop type engaging element formed by a knitting method, and two types of hook-and-loop fasteners are used facing each other. Alternatively, it is possible to use one type of engaging element typified by a mushroom-like shape, or one in which hooks and loops are mixed on the same surface fastener surface. In addition to these, as a sound reduction type, a type has been developed that suppresses the buzzing sound that occurs when two surface fasteners are peeled off. This type is suitable when a hook-and-loop fastener is used in the clothes of the present invention.
The type of the hook-and-loop fastener is not restricted, and any type that can be fixed to the substrate can be used.

For the plastic substrate, a material that is compatible with attachment methods such as a type in which an adhesive double-sided tape is fixed to the back surface, a type in which threads are sewn with an industrial sewing machine, and a high-frequency welding method are used. For sewing and fixing, it is an essential condition that the needle is good, and there is a limit to the thickness and hardness, and PP, PVDC, PET, etc. are subject to cost in the case of general-purpose resins. A sheet having a thickness of 0.2 mm to 2 mm is used. A preferred range is 0.5 mm to 1.0 mm. If it is an adhesive fixing method, a thicker one can be used.
In addition, a foamed PP sheet as a low foamed sheet is preferable for obtaining a thickness that makes it easy to obtain a feeling during fitting. As a special sheet, a resin-treated paperboard or a laminate sheet of various films can be used. If decoration is more important than cost, a glossy metal sheet, a stone plate, and the like can be used as materials if they have excellent rigidity and slipperiness when engaged. This includes wires that can be contoured.

  The manufacturing method will be described in the case of a small surface fastener in which a surface fastener is fixed to a substrate with an adhesive. An example of punching out six small square hook-and-loop fasteners shown in FIG. 12 will be described. It will be punched out leaving the release paper and sold in a bag as a product with 6 pieces. Create a layout that provides trim margins around the six hook-and-loop fasteners, and place it in a two-pitch arrangement as shown in FIG. 12, and punching is a punching die that combines concave and convex locking pieces. Punch out.

  The process arrange | positions various apparatuses so that manufacture using a continuous sheet can be performed as shown in FIG. In the manufacture of the small surface fastener, a general lamination and punching continuous process or dividing process can be applied. In the uppermost stream, a roll (12) of a plastic thin plate is put on a stand, and the thin plate of the substrate is fed out. Next, the tape is drawn out from a roll (13) of a double-sided pressure-sensitive adhesive tape for attaching an adhesive for fixing the small surface fastener to the base material, and laminated on a sheet of plastic thin plate through a pressure roll. Next, the tape of the narrow surface fastener is drawn out from the roll (14) of the surface fastener and is pressure-bonded to the previous laminate sheet. This hook-and-loop fastener is provided with a release paper, which is peeled off and transferred to the laminate sheet while being wound up. It is also possible to incorporate a device that rolls an adhesive material and dries without using a double-sided adhesive tape.

The sheet laminated on the three layers is controlled via a pressure-bonding / feeding roll (15) and a feed amount / position detector (16), and supplied to a punching machine (17). In this process diagram, the punching machine is a die press that performs intermittent punching. Next, the punched sheet enters a trimming device (18) that separates the residue from the product. A wooden mold incorporating a pressing rubber and a protruding jig is attached to this device.
Next, the punched-out locking piece is pushed out here and struck into the bucket, and is deposited in the product bucket (19). The remaining part other than the product is wound on a winding roll. Instead of this winding, it can also be bundled into a bucket as a small piece while cutting with a vertical rotary blade.

  Instead of the intermittent flat punching method shown here, it is also possible to punch using a mold with a rotary continuous device. In addition, the trimming device can also be performed by a pin-rotating type of depression and pop-up method. If there are conditions that allow mass-produced products to be manufactured as standard products, equipment with high production efficiency can be obtained.

  The above explanation is about fixing a surface fastener to a substrate having excellent rigidity and providing a fitting hole or protrusion on a part of this substrate, but an engagement function as an alternative to this surface fastener. It is possible to use a male or female snap hook made of metal or resin. The hook is generally used in a size smaller than that of a normal button, and has a size that is difficult to handle with a fingertip and is difficult to position. Because of this drawback, its use is limited and not widespread. However, these disadvantages can be eliminated by combining the engagement methods using the fitting means of the present invention. The hook group is formed in a plastic substrate (not shown). Three hooks can be easily fixed to the substrate in a zigzag manner. Hooks incorporating this method can reliably determine the positions of male and female hooks, so that a plurality of hooks can be combined at the same time and the palm can be used at the same time without fear of deviation. The hook can be fixed to the substrate by fusion or integral molding.

The present invention secures a small piece of two types of locking pieces, to which an engaging means represented by a hook-and-loop fastener is fixed, to a base material such as a soft cloth, so that the position of the rough engaging tool can be approximated with a fingertip sensation. Next, the projecting portion provided on the convex engaging piece used to face the notch provided on a part of the concave engaging piece is fitted to determine the exact position, and in this state, the hook-and-loop fastener By pressing, the locking pieces can be engaged with each other without worrying about misalignment by blind touch.
By attaching this function, it is possible to manufacture a garment that makes it easy for a disabled person or a disabled person to attach and detach.
In addition, by using this engagement tool with a hook-and-loop fastener, it is possible to increase options other than buttons and zippers that are generally used in the design of clothes that require fashionability.
