In recent years, in various articles, especially clothing, such as clothing, bags, and footwear, the zipper attached to it has been regarded as an element of design, and it is required to improve the overall appearance quality of articles including zippers. . Further, in the prior art, the zipper is usually attached linearly to the article as the member to be attached to the zipper. However, in recent years, the zipper is attached to the zipper in a state of, for example, a curved shape from the viewpoint of convenience or design of the article. Install the components.

In the zipper described in the above-mentioned Patent Document 1, the main body portion of the fastener fabric to which the fastener element of the continuous fastener element is fixed is sewn and fixed to an article (for example, a clothing item or the like) to be a zipper-mounted member. Since the opening and closing portion is used, in order to smoothly sew the zipper and the zipper-attached member by the sewing machine, it is necessary to ensure the width dimension of the zipper main body portion of the zipper chain cloth which is exposed on the outer side in the width direction of the fastener fabric. As a sewing allowance. In the case where the zipper is attached to the zipper-attached member in a curved state or the like, the main body portion of the chain corresponding to the outer peripheral portion of the zipper is partially swollen or sunk, and is present in a considerable amount. The chain extension of the inner circumference of the zipper (the extension of the chain which is curved in a concave shape) generates a large wavy wrinkle.

In order to solve such a problem, the inventors of the present application have previously attached a zipper to a chain without a zipper chain and a chain belt using the zipperless chain cloth in the international application number PCT/JP2013/083604. The article was filed internationally.

As shown in FIG. 15 and FIG. 16, the fastener-free chain link of the application has a plurality of continuous fastener elements 212 formed by a single filament, and the fastener element 212 is sewn by the sewing thread 213. A row of narrow-width fastener element 214, the fastener element 214 is inserted into the upper and lower leg portions 212b, 212c of the fastener element 212 along the length of the zipper, and the sewing line 213 and the upper leg portion 212b and the lower leg portion 212c The sprocket fixing members 214 are pierced between the zipper elements 212 that are in contact with each other and are adjacent to each other in the longitudinal direction of the zipper, thereby sewing the fastener elements 212 and the sprocket fixing members 214. Moreover, the chain of the zipper-free chain cloth is relatively In a state in which the cloth 205 of the garment 201 as the zipper-attached article is aligned, the sewing machine for zipper sewing is sewn and fixed to the fabric 205 by the lock stitching of the second sewing thread 206, thereby obtaining a zip-free use. A zippered item is formed by a chain of chain cloth.

According to the fastener tape without a zipper chain as described above or the zipper-attached article using the fastener tape without the zipper chain cloth, an excellent effect is obtained in that the weight of the zipper can be reduced or the cost can be reduced, and even if In a state in which the zipper is bent into a curved shape or the like, the fastener tape without the zipper chain can be attached to the zipper-attached member with good appearance.

In addition, as in recent years, articles such as zippered clothes are produced in a small number of varieties, and the fabrics 205 shown in Figs. 15 and 16 are also used in various thicknesses, for example, in connection with the use or design of the articles. When the thickness of the cloth 205 in the 16 is thickened, the cloth 205 or the plurality of fastener elements 212 are pressed against the upper and lower blades 234 of the slider 230, and the sliding resistance of the slider 230 is increased. The cloth 205 bites into the gap between the flap 233 and the lower flap 234 of the slider 230, so that the sliding operation of the slider 230 cannot be performed briskly. Further, there is a problem that the sewing thread 213 and the second sewing line 206 are easily broken due to friction with the slider 230.

In order to eliminate such a problem, for example, a slider in which the interval between the upper and lower blades is set to be relatively large, or a plurality of sliders in which the interval between the upper and lower blades is prepared is considered.

However, in the case of the former, for example, when a zipper is formed by attaching a chain without a zipper chain to a thin fabric, the zipper is easily swayed in the sprocket guiding path of the slider when the slider slides. In addition, the sliding property of the slider is lowered, or the meshing of the fastener elements is deteriorated. On the other hand, in the latter case, a plurality of kinds of sliders which must be prepared in accordance with the thickness of the cloth are generated, so that the burden on the cost becomes large, and it is not economical.

The present invention has been made in view of the above problems, and a specific object thereof is to provide a chain belt without a zipper chain cloth, thereby realizing light weight and cost reduction of the zipper, that is, An economical excellent fastener-free chain link that can be easily mounted in a state of being bent into a curved shape or the like, and which can smoothly slide the slider independently of the thickness of the attached member (cloth) of the zipper. a zipper without the zipper chain of the chain belt, and an zipper-attached article having the zipper.

In order to achieve the above object, a chain link without a zipper chain provided by the present invention is attached as a basic structure to a chain attachment portion that is disposed opposite to the zipper-mounted member, and has a plurality of consecutive zipper fasteners. And the narrow-chain fastener fixing member is disposed along the longitudinal direction of the zipper, and sutures the fastener element by the sewing thread; the fastener element has: an engaging head; an upper leg and a lower leg portion extending in the width direction of the zipper from the engaging head portion between the sprocket fixing members and the like; and a connecting portion extending from the upper leg portion or the lower leg portion and coupled to the zipper length And the above-mentioned lower leg portion has a first extending portion that continuously extends in the width direction of the zipper from the engaging head portion; a differential portion that is curved from the first extending portion toward the upper leg portion; and a second extending portion that is closer to the upper leg portion than the first extending portion from the first extending portion along the zipper width The accommodating space portion accommodating the link attaching portion of the zipper-attached member is formed below the second extending portion by the step portion, and the accommodating space portion includes the first extending portion The height dimension from the lower surface to the lower surface of the second extension portion.

The lower surface is 5% or more and 25% or less of the height dimension of the upper surface of the upper leg portion.

Further, in the fastener tape without a fastener chain according to the present invention, it is preferable that the second leg portion of the upper leg portion and the lower leg portion are sewn on the double chain seam of the sewing thread. The sprocket fixing member is described. In this case, it is preferable that the thread hook line of the sewing thread is disposed across the upper leg portion of the fastener element, and the stitching line of the sewing thread spans the second extending portion of the lower leg portion, and The fastener element is pierced between the adjacent fastener elements, and is interlaced with the above-mentioned line hook.

Further, in the fastener tape of the zipper-free chain of the present invention, it is preferable that the fastener element is a belt-shaped member having a woven structure, a belt-shaped member having a warp-knitted structure, and a belt-shaped member including a nonwoven fabric. Or a synthetic resin film forming member.

Further, according to the present invention, a zipper without a zipper chain cloth is provided, and the zipper without the zipper chain cloth having the above-described configuration is attached to the accommodating space portion in a state in which the sprocket attaching portion is housed in the accommodating space portion. The chain attachment portion of the zipper-mounted member is slidably attached to the element row formed by the fastener element.

Further, according to the present invention, there is provided a zipper-attached article comprising the zipper having the zipper-free chain fabric of the above configuration.

The zipper-free chain belt (hereinafter, also referred to simply as "chain belt") provided by the present invention has a continuous zipper element formed of a monofilament and which is spiral or serrated, and a narrow chain. Tooth fixing member. Further, the narrow sprocket fixing member is inserted into the upper and lower leg portions of the fastener element along the longitudinal direction of the zipper, and the continuous zipper fastener is stitched in a row by the sewing line to be disposed between the upper and lower legs. A narrow-width fastener element.

Here, the zipper chain is used to fix the outer surface of the foot or the lower leg above the zipper element (the surface opposite to the surface opposite to the upper and lower leg portions) in contact with the upper leg portion or the lower leg portion. The belt-shaped members of the upper leg portion and the lower leg portion are different from the fastener element fixing member of the present invention inserted between the upper and lower leg portions. That is, the chain belt of the present invention is not provided with a so-called fastener chain cloth for fixing the upper leg portion and the lower leg portion on the outer side of the upper leg portion or the lower leg portion, and is configured as a zipper having a novel structure different from the conventional general chain tape. Chain belt of chain cloth.

Moreover, in the present invention, the sewing line contacts and spans the foot and the lower portion of each of the fastener elements. The leg portions are pierced with the fastener element between the fastener elements adjacent to each other in the longitudinal direction of the zipper, whereby the continuous fastener element is sewn and fixed to the fastener element. In this case, it is preferable that the sprocket fixing member is not easily stretched and contracted in the longitudinal direction of the zipper as in the prior art, and has a difficult-to-stretch structure which is not easily stretched in the longitudinal direction of the zipper.

In the chain belt which does not use a fastener chain cloth in the present invention, the fastener element which is inserted between the upper and lower leg portions (especially the fastener element fixing member which is difficult to stretch) is sewn with the fastener element. Therefore, even if the zipper cloth as in the prior art is not used as the constituent member of the fastener tape, the mounting pitch of the fastener element can be stably maintained by the fastener element.

Therefore, by attaching the chain belt of the present invention to the zipper-attached member to form a zipper or a zipper-attached article, weight reduction or cost reduction of the zipper can be achieved, or the zipper chain cloth can be used for the previous function. Different purposes (such as decorative purposes, etc.).

Further, according to the present invention, the chain belt or the zipper can be configured without using a fastener chain. Therefore, for example, the fastener tape of the present invention can be stably attached to the zipper-attached member in a state of being bent or bent. Moreover, in this case, the ridges or dents of the zipper chain cloth which is a problem in the previous zipper, or the wavy wrinkles or the like are not generated, so that the appearance (appearance quality) of the zipper-attached article can be improved.

Further, in the present invention, each of the lower portions of the fastener element has a first extension portion that continuously extends in the width direction of the slider from the meshing head portion, and a step portion that is bent from the first extension portion to the upper leg portion side. And a second extending portion extending in the width direction of the slider from the stepped portion closer to the upper leg portion than the first extending portion. Further, each of the fastener element teeth has a stepped portion at the lower leg portion, and has a housing space portion formed below the second extension portion and accommodating the link attachment portion of the zipper-attached member, the accommodating space portion having the lower leg portion The height dimension of the lower surface of the first extending portion to the lower surface of the second extending portion.

When the fastener tape of the present invention is attached to the accommodating space portion in a state in which the fastener tape attaching portion is housed in the accommodating space portion, the fastener element is attached to the zipper-attached member (for example, the fabric). The lower surface of the first extension of the lower middle part of the foot to the upper part of the upper part The height of the face is fixed in a fixed size to ensure the overall height of the chain.

Further, at the same time, even if the zipper-attached member (cloth) has various thicknesses, the thickness of the zipper-attached member can be absorbed by the accommodating space portion of the zipper element, and the lower surface of the zipper-mounted member can be The height dimension of the upper surface of the upper part of the zipper element is set to be smaller, which is the height dimension of the lower surface of the first extension part of the lower part of the zipper element to the upper surface of the upper leg part (ie, the overall height of the chain belt) Size) below.

Therefore, in the element row formed by the fastener elements of the fastener tape of the present invention, when the slider of the upper blade and the lower blade is set to a specific size, for example, even a zipper is slidably mounted. The thickness of the attached member is thin, and the height of the entire chain is also secured by the first extension of the upper and lower leg portions of the fastener element, so that the slider can be less likely to be generated when the slider slides. Shake.

On the other hand, for example, even if the thickness of the zipper-attached member is thick, the thickness of the zipper-attached member can be absorbed by the accommodating space portion of the zipper element, and the height dimension of the entire chain can be prevented from being larger than the above. The fixed height dimension of the lower surface of the first extending portion of the lower leg portion to the upper surface of the upper leg portion. Thereby, when the sliding member is slid, the zipper element or the zipper can be effectively prevented from being pressed against the upper or lower wing of the sliding member by the mounting member, or the zipper is bitten into the sliding member by the mounting member, thereby stably Make sure the slider slides lightly and smoothly. Moreover, the sewing thread for the stitched fastener element is also not easily brought into firm contact with the slider, so that the problem that the sewing thread is easily broken is also eliminated.

In the chain belt of the present invention, the height dimension of the lower surface of the first extending portion to the lower surface of the second extending portion in the lower leg portion of the fastener element is set to be the lower surface of the first extending portion to the upper leg portion. The height of the upper surface is 5% or more and 25% or less. Thereby, the fastener tape of the present invention can be stably attached to the fastener tape attachment portion of the zipper-attached member in a state where the fastener element is held in an appropriate posture, and when the fastener tape is attached to the zipper-mounted member, The thickness of the zipper-mounted member is appropriately absorbed by the accommodating space portion of the fastener element. Further, when the zipper is formed, the posture of the fastener element can be prevented from being inclined in the sprocket guiding path of the slider.

Further, in the chain belt of the present invention, the second extending portion of the upper leg portion and the lower leg portion is sewn to the element fixing member by the double chain slit of the sewing line. Thereby, when the fastener element is sewn to the fastener element fixing member, the leg portion and the lower leg portion of the fastener element can be efficiently sewn and fixed to the fastener element fixing member, so that productivity can be improved. Further, the upper leg portion and the lower leg portion are firmly fixed to the element fixing member by the double chain slit of the sewing line, and further, for example, even when the sewing line is broken, the sewing line can be prevented from being scattered.

In particular, in this case, the thread hook line of the double-stitch stitching line is disposed across the leg portion of the fastener element. Further, the sewing thread of the sewing thread spans the second extending portion of the lower leg portion, and pierces the fastener element between the fastener elements adjacent to each other to be interlaced with the thread hook line. Thereby, when the fastener tape of this invention is attached to the fastener tape mounting part of a zipper mounting member, the fastener can be covered by the mounting member, and the sewing thread of a sewing thread can be protected. Thereby, the needle thread of the sewing thread is hardly exposed to the outside, and therefore, it is less likely to be cut than the thread hook line of the sewing thread which crosses the leg portion above the fastener element, and the sewing thread can be more effectively prevented from being scattered.

Further, in the fastener tape of the present invention, as the fastener element, a belt-shaped member having a woven structure, a belt-shaped member having a warp-knitted structure, a belt-shaped member including a nonwoven fabric, or a synthetic resin film-forming member can be used. By forming the element fixing member by such a belt-shaped member or a film member, the element fixing member can be prevented from stretching and contracting in the longitudinal direction of the zipper with a simple structure, whereby the fastener element in the chain can be stably held. Installation spacing.

Moreover, the cross-section of the strip member or the membrane member has a flat shape having a small dimension in the thickness direction and a large dimension in the width direction, so that the strip member can be easily inserted between the lower leg portions of the fastener element or Membrane member. Further, when the lower leg portion of the fastener element is sewn to the belt member or the film member by using a sewing machine, for example, the sewing machine needle can be stably pierced by the belt member or the film member, and the sewing operation can be smoothly performed.

Further, in the zipper provided by the present invention and the zipper-attached article, the zipper-free fastener tape having the above-described configuration is attached to the chain of the zipper-attached member in a state in which the fastener-attached portion is housed in the accommodating space portion. With mounting part. Also, formed by zipper teeth The chain of teeth is slidably mounted with a slider.

The zipper without the zipper chain and the zipper-attached article constructed in this manner are sewn with the fastener element in the sprocket fixing member as described above, so that the zipper chain cloth can be stably used as the constituting member of the zipper. Keep the mounting distance of the zipper teeth.

In other words, in the present invention, the mounting pitch of the fastener elements can be stably maintained to a specific size, and the fastener stringer which is a necessary constituent member of the slide fastener can be omitted, so that the weight of the slide fastener can be reduced or the cost can be reduced.

Further, when the zip fastener is omitted and the zipper is formed, the zipper-attached member can be stably attached to the zipper-attached member, for example, in a state in which the bending is bent. Moreover, in this case, the ridges or dents of the zipper chain cloth which is a problem in the previous zipper, or the wavy wrinkles or the like are not generated, so that the appearance (appearance quality) of the zipper-attached article can be improved.

Further, by the height dimension of the lower surface of the first extending portion of the lower leg portion of the zipper element to the upper surface of the upper leg portion, the height of the entire chain belt is stably secured to a fixed size, and even if the zipper is The link attaching portion of the mounting member (cloth) has various thicknesses as long as the chain attaching portion has a lower height of the lower surface of the first extending portion to the lower surface of the second extending portion of the lower leg portion of the fastener element The thickness of the fastener tape can be surely absorbed by the accommodating space portion of the fastener element.

Thereby, for example, even when the thickness of the link attaching portion in the zipper-mounted member is thin, the sway of the slider is less likely to occur when the slider slides, and even in the zipper-mounted member When the thickness of the mounting portion is thick, it is possible to stably ensure the smooth and smooth sliding of the slider.

As shown in Fig. 1, the zipper 3 of the garment of the first embodiment has a pair of left and right chain belts 1 having a chain row 11, a fabric 5 having a belt attachment portion 5a to which the chain 1 is attached, and The slider 30 is slidably disposed along the element row 11 of the chain belt 1. Further, although not shown, a first stopper that prevents the slider 30 from coming off is disposed adjacent to the front end of the element row 11, and is adjacent to the rear end of the element row 11 so as to straddle the left and right chain belts 1. The mode is configured with a second stop.

Each of the left and right chain belts 1 has a continuous fastener element 20 in which a monofilament is formed into a spiral shape, and a narrow-tooth fastener element 14 in which the fastener element 20 is fixed by stitching of the first sewing thread 13 Each of the fastener tapes 1 is configured such that the fastener tape 1 without the fastener chain is disposed on the outer side of the upper leg portion 22 and the outer side of the lower leg portion 23 of the fastener element 20.

Here, a cross-sectional view of the article with the fastener stringer of the first embodiment is shown in Fig. 2, and a cross-sectional view of the fastener tape is shown in Fig. 3.

The fastener element 20 has an engaging head portion 21, an upper leg portion 22 and a lower leg portion 23 extending from the meshing head portion 21 in the width direction of the zipper, and a joint portion 24 extending from the upper leg portion 22 or the lower leg portion 23, And connected to the fastener element 20 adjacent to the longitudinal direction of the zipper. In this case, the fastener element 20 can be decorated by coloring or plating the fastener element 20 itself.

Furthermore, in the present invention, among the two leg portions of the fastener element extending from the meshing head, the lower leg portion refers to the leg portion of the zipper-attached member (cloth) directly contacting the side, and the upper leg portion refers to the zipper. The leg portion on the side where the member (cloth) is separately disposed.

The engaging head portion 21 of the zipper element 20 is provided to straddle the upper leg portion 22 and the lower leg portion 23 A portion formed in the up-and-down direction and bulging in the front-rear direction in the middle portion of the up-and-down direction. The upper leg portion 22 extends substantially parallel to the width direction of the slider from the meshing head portion 21, and the upper surface (upper end portion) of the upper leg portion 22 is disposed substantially parallel to the front surface of the cloth 5.

The lower leg portion 23 of the fastener element 20 has a first extending portion 23a that continuously extends in the width direction of the slider from the meshing head portion 21, and a step portion 23b that is curved from the first extending portion 23a to the side of the leg portion 22 And the second extending portion 23c extending from the step portion 23b closer to the upper leg portion 22 than the first extending portion 23a in the width direction of the slide. In this case, the lower surface (lower end portion) of the first extending portion 23a and the lower surface (lower end portion) of the second extending portion 23c are disposed substantially in parallel with the front surface of the cloth 5, and the second extending portion 23c is provided. It is formed longer than the first extension portion 23a in the width direction of the slide.

Further, the lower leg portion 23 is formed with the step portion 23b, and the lower surface of the second extending portion 23c is disposed above the lower surface of the first extending portion 23a in the element height direction. In this case, the dimension (height dimension) B in the up-and-down direction between the upper surface of the upper leg portion 22 and the lower surface of the second extending portion 23c of the lower leg portion 23 is set smaller than the upper surface of the upper leg portion 22 and The height dimension A between the lower surfaces of the first extending portions 23a of the lower leg portions 23. Further, the fastener element 20 is formed by the following leg portion 23 having the step portion 23b as described above, and the housing space portion 25 for accommodating the link attaching portion 5a of the cloth 5 is formed below the second extending portion 23c.

In this case, the height dimension A of the lower surface of the first extending portion 23a which is the height dimension of the fastener element 20 to the upper surface of the upper leg portion is set to be smaller than, for example, the upper blade 33 formed on the slider 30. The space between the lower surface of the partition 33a and the upper surface of the lower wing 34. Further, it is preferable that the height dimension A of the fastener element 20 is set to prevent the left and right fastener elements 20 from being shaken in the vertical direction in the element guide path of the slider 30, for example, below the intermediate partition 33a. The distance between the surface and the upper surface of the lower wing 34 is 85% or more.

Further, the accommodating space portion 25 of the fastener element 20 includes a height C of the lower surface of the first extending portion 23a to the lower surface of the second extending portion 23c, and the height of the accommodating space portion 25 (ie, The height dimension C of the lower surface of the first extending portion 23a to the lower surface of the second extending portion 23c is set to be 5% or more and 25% or less of the height dimension A of the fastener element 20.

The height C of the accommodating space portion 25 is 5% or more of the height dimension A of the fastener element 20, and is represented by a specific numerical value. The height C of the accommodating space portion 25 is 0.1 mm or more, whereby the accommodating space portion can be appropriately secured. The size (height) of 25 is such that when the fastener tape 1 is attached to the fabric 5, the fabric 5 can be accommodated in the accommodating space portion 25, and the step portion 23b of the lower leg portion 23 absorbs the thickness of the fabric 5.

The term "absorbent" as used herein means that the total thickness of the dimension B and the fabric 5 does not exceed the dimension A by the height dimension C of the accommodating space portion 25, or the size of the excess is limited even if it exceeds. That is, when the height dimension A of the fastener element 20 is used as a reference, the thickness of the cloth 5 is reduced, and in other words, the thickness of the cloth 5 is not simply added to the height dimension A, but by income. In the height dimension C of the accommodating space portion 25, the thickness of the cloth 5 is not directly reflected in the height dimension of the entire fastener element 20 to which the cloth 5 is attached. In other words, the state of being accommodated in the accommodating space portion 25 means that the edge portion of the fastener tape attaching portion 5a of the fabric 5 as the zipper-attached member is attached to the stepped portion 23b in the width direction of the zipper. status.

As described above, the thickness of the cloth 5 is absorbed by the step portion 23b of the lower leg portion 23, and when the zipper 3 is formed, the chain belt 1 is not easily brought into contact with the lower wing plate 33 and the lower wing plate 34 of the slider 30 at the same time. Therefore, it is possible to suppress the sliding resistance of the slider 30 from becoming large, so that the sliding operation of the slider 30 can be performed briskly. Further, the first stitching line 13 for sewing the fastener element 20 to the fastener element fixing member 14 and the second sewing thread 6 for sewing the fastener tape to the fabric 5 can be prevented from being broken by friction with the slider 30. Further, in the first sewing line 13, the needle thread 13b that spans the second extending portion 23c of the lower leg portion 23 is covered by the cloth 5, so that the needle thread 13b is not exposed to the outside.

On the other hand, by making the height dimension C of the accommodating space portion 25 25% or less of the height dimension A of the fastener element 20, the second extension portion 23c of the lower leg portion 23 can be prevented from being too close to the upper leg portion 22. Thereby, the second extension portion 23c and the upper leg portion 22 of the lower leg portion 23 can be appropriately ensured. The interval therebetween suppresses the sprocket fixing member 14 from being excessively crushed, thereby preventing the sprocket fixing member 14 from being bent or undulated in the front-back direction. Further, when the zipper 3 is formed, the distance between the second extending portion 23c (or the cloth 5) of the lower leg portion 23 and the lower blade 34 of the slider 30 can be prevented from becoming excessively large. Thereby, when the left and right element rows 11 are engaged, the posture of the fastener element 20 in the following element guide path of the slider 30 is not easily inclined, so that the meshing failure can be prevented.

Furthermore, in the present invention, the height dimension A of the fastener element, the height dimension B between the upper surface of the upper leg portion and the lower surface of the second extension portion 23c of the lower leg portion, and the height dimension C of the accommodating space portion 25 The size or ratio of the chain can be arbitrarily determined in consideration of the size of the chain belt and the type or thickness of the fastener-attached member to which the fastener tape is attached. Here, as an example, each of the chain belts 1 of the first embodiment will be described. The specific size of the size.

In the chain belt 1 of the first embodiment, the height dimension A of the fastener element 20 is set to 2.6 mm, and the width dimension of the fastener element 20 (i.e., one end of the meshing head 21 in the fastener element 20 side to the link) The dimension D of the other end of the portion 24 side in the left-right direction is set to 4.9 mm. Further, the height B between the upper surface of the upper leg portion 22 and the lower surface of the second extending portion 23c of the lower leg portion 23 is set to 2.1 mm, and the height C of the accommodating space portion 25 is set to 0.5 mm.

Further, in the first embodiment, the boundary between the step portion 23b of the lower leg portion 23 and the second extending portion 23c and the end portion of the connecting portion 24 of the fastener element 20 in the width direction of the fastener element 20 The width dimension E is set to 2.8 mm. In this case, it is preferable that the width dimension E is set to be 20% or more and 70% or less of the width dimension D of the fastener element 20.

By making the width dimension E 20% or more of the width dimension D of the fastener element 20, the fastener element 20 can be stably sewn to the fastener element 14 by the following double chain stitch of the first sewing line 13. . Moreover, by making the width dimension E 70% or less of the width dimension D of the fastener element 20, the width dimension of the first extension portion 23a of the lower leg portion 23 can be appropriately ensured, and the fastener chain is less likely to be formed when the zipper 3 is formed. The teeth 20 are shaken relative to the slider 30.

Further, in the case of the first embodiment, as shown in FIGS. 2 and 4, the left and right chain belts are used. In the state of being engaged, the so-called chain width dimension F of the width of the edge of the connecting portion 24 on the side of the connecting portion 24 of the fastener element 20 to the side of the connecting portion 24 of the other fastener element 20 is set to 8.2 mm.

The sprocket fixing member 14 for mounting the zipper element 20 of the first embodiment at a specific distance is a belt-like member having a woven structure, preferably a belt-like member woven into a flat woven structure. The woven fabric is woven into a single layer by a plurality of warp yarns and a weft yarn in which two single yarns are combined to form a single yarn. The strip-shaped member which is woven into a flat woven structure has a flat cross-sectional shape having a small dimension in the thickness direction and a large dimension in the width direction, and has a telescopic shape which is woven by the weft yarn to suppress the expansion and contraction of the zipper in the longitudinal direction. A structure that is not easily retractable. Further, an ear portion formed by joining the loop-back ends by the yarns in the next weft by sequentially hooking the one side edge portion of the belt-shaped member is formed.

Further, as the sprocket fixing member 14, in addition to the belt-shaped member woven into the woven fabric structure, a belt-shaped member having a warp knitting structure in which chain knitting yarns are arranged in each warp, and a non-woven fabric may be used. A belt-shaped member, a synthetic resin film-forming member, or the like.

The size of the fastener element 14 in the unloaded state in the width direction of the chain (also referred to as the width direction of the chain fabric) is two times or more the size of the thickness direction of the chain fabric, and more preferably in the fastener element. The size in the width direction of the zipper is set to be 2.5 times or more and 3.5 times or less the size of the chain thickness direction.

Here, the no-load state refers to a state in which the fastener element 14 is removed from the fastener element 20, and a manual external force such as stretching or compression is not applied to the fastener element 14. The sprocket fixing member 14 has a structure that is not easily stretched in the longitudinal direction of the zipper by having the size as described above.

Further, as the sprocket fixing member 14, for example, the core cord is inserted into the upper and lower leg portions 22, 23 of the fastener element 20, and the core cord is obtained by braiding the plurality of wires around the state. , called the so-called braided rope. However, in the braided rope in which the plurality of wires are bundled in this manner, the plurality of wires extend along the length of the zipper, and the respective wires are at the width of the zipper. Since the direction and the zipper thickness direction have undulations (crimping), it is easy to expand and contract, and thus is not suitable as the sprocket fixing member 14.

Further, in the first embodiment, by using the fastener element 14 having a flat shape in cross section, the fastener element 14 can be easily inserted between the upper and lower leg portions 22, 23 of the fastener element 20. Further, when the upper and lower leg portions 22 and 23 are sewn to the fastener element fixing member 14 by using the sewing machine as described below, the sewing machine needle can be stably pierced by the fastener element fixing member 14, and the sewing operation can be smoothly performed.

Next, a method of manufacturing the above-described chain belt 1 of the first embodiment will be described.

First, the fastener element 20 of the first embodiment is molded. For example, after a thermoplastic resin monofilament such as polyamide or polyester is wound into a spiral shape and molded, a sprocket is inserted between the formed upper leg portion 22 and the lower leg portion 23 in the longitudinal direction of the sprocket (the zipper length direction). Fixing member 14. At this time, the element fixing member 14 is inserted into the fastener element 20 so that one end portion in the width direction thereof is in contact with the coupling portion 24 of the fastener element 20.

Then, a specific portion of the lower leg portion 23 on the side of the connecting portion 24 is pressed toward the upper leg portion 22 by hot pressing or the like while being sandwiched between the upper and lower leg portions 22 and 23, and is formed in the lower leg portion 23 by hot pressing or the like. Step portion 23b. At this time, by pressing the lower leg portion 23, the element fixing member 14 is sandwiched (held) between the upper leg portion 22 and the second extending portion 23c of the lower leg portion 23. Thereby, the fastener element 20 of the first embodiment is molded.

Further, in the fastener element 20 obtained in this manner, the fastener element 14 that is in contact with the coupling portion 24 is sandwiched between the upper leg portion 22 and the second extension portion 23c of the lower leg portion 23 The stitching machine for fastener element sewing is used to fix the upper leg portion 22 and the second extending portion 23c of the lower leg portion 23 to the front surface and the back surface of the element fixing member 14 by the double chain stitch of the first stitching line 13. Thereby, the fastener tape 1 of the first embodiment shown in FIGS. 3 to 5 was produced.

In this case, the thread hook line 13a of the first stitching line 13 of the double chain stitch is on the front side of the element fixing member 14, and is in direct contact with the upper leg portion 22 of the fastener element 20 and spans the upper leg portion 22. . Further, the needle thread 13b of the first sewing thread 13 is on the back side of the fastener element fixing member 14, and is pulled. The second extending portion 23c of the lower leg portion 23 of the chain sprocket 20 directly contacts and straddles the second extending portion 23c, and pierces the sprocket fixing member 14 between the mutually adjacent fastener elements 20, and the sprocket fixing member The line hook lines 13a on the front side of the 14 are staggered.

Thereby, a seam is formed between the fastener elements 20, and the first sewing portion formed by the double chain stitch of the first sewing thread 13 is formed to be exposed on the front side and the back side of the element row 11. Further, since the portion of the second extending portion 23c which is longer than the first extending portion 23a of the lower leg portion 23 is sewn to the element fixing member 14, the sewing step can be stably performed.

In this manner, the fastener element 20 is fixed to the fastener element 14 which is not easily stretchable in the longitudinal direction of the zipper by the double chain slit of the first sewing thread 13, and the fastener element 14 can hold the fastener element 20 as the fastener element. The shape is maintained, and the mounting pitch of the fastener elements 20 (in other words, the interval between the engaging heads 21) can be fixed.

Further, since the first stitching line 13 pierces the fastener element fixing member 14 and holds the fastener element 20, the first sewing thread 13 is less likely to be displaced from the piercing position of the fastener element fixing member 14, and the fastener element 20 can be placed up and down. The leg portions 22, 23 are fixedly supported at a specific position of the fastener element fixing member 14. Therefore, the upper and lower leg portions 22, 23 can be prevented from moving relative to the fastener element fixing member 14.

Further, since the double stitching is used as the stitch form of the first stitching line 13, and the strength of the joint is excellent, it is preferable that even if the first stitching line 13 is broken, the scattering of the first stitching line 13 is less likely to occur. Further, by sewing the woven band-shaped member 14 and the fastener element 20 with a double chain stitch, the fastener tape 1 without the fastener chain can be manufactured with high productivity.

Further, it is known that when the fastener element is sewn to the fastener stringer by the double chain stitch of the sewing thread, if the needle thread of the sewing thread is cut, the thread hook line with the sewing thread is cut. The sewing portion (sewing line) which is easy to suture the fastener element is scattered.

On the other hand, in the first embodiment, the needle thread 13b of the first stitching line 13 in which the double chain stitch is formed is sewn to the second extending portion 23c of the lower leg portion 23. In other words, when the needle thread 13b which is easily scattered in the sewn portion is placed on the lower leg portion 23 side, the fastener tape 1 of the first embodiment is sewn to the fabric 5 to form the zipper 3. When the exposed surface side of the needle thread 13b is covered and protected by the cloth 5, the needle thread 13b is less likely to be directly stressed from the outside, and the needle thread 13b can be prevented from being cut.

As a result, the first sewing portion formed by sewing the double chain slit of the first sewing thread 13 of the fastener element 20 is more difficult to be scattered, so that the life of the fastener tape 1 and the fastener 3 can be extended.

Further, in the present invention, as the stitch form of the first stitching line 13, a double chain stitch such as a lock type stitch can be used.

The fastener tape 1 of the first embodiment manufactured in this manner is formed without using a fastener tape which is a constituent member necessary for the previous fastener tape, and thus is lighter in weight than the previous fastener tape, and can be manufactured at a lower cost. The inhibition is lower.

Further, since the fastener element 12 is sewn to the fastener element 14 having a structure that is less likely to expand and contract in the longitudinal direction of the slide fastener, the fastener element can be stably held by the fastener element 14 without using the fastener chain member. 20 installation spacing. Further, even if the chain belt 1 of the first embodiment is bent into a curved shape or the like, it does not cause ridges or depressions of the fastener chain cloth or wavy wrinkles as in the conventional chain belt having the fastener chain.

Further, as shown in FIG. 6 and FIG. 7, the fastener tape 40 shown in FIG. 8 is used in a state in which the fastener tape 1 of the first embodiment is aligned with respect to the fabric 5 to be the fastener attached member. The cloth 5 is sewn and fixed by the lock stitch of the second stitching line 6. In this case, as the cloth 5, a thickness having a thickness equal to or less than the size of the height C of the lower surface of the first extending portion 23a of the fastener element 20 to the lower surface of the second extending portion 23c is used.

Further, when the sewing step of the sewing machine 40 for sewing the fastener tape is performed, the leg portion 23 of the fastener element 20 of the first embodiment is provided with the step portion 23b to position the cloth 5 with respect to the chain tape 1. When the alignment is performed, the step portion 23b can be used as a standard for positioning, and the cloth 5 can be prevented from exceeding the step portion 23b and extending to the side of the first extending portion 23a of the lower leg portion 23 (too close to the meshing head portion 21 side). ).

Further, since the step portion 23b is provided by the leg portion 23 under the fastener element 20, the orientation of the front side of the chain belt 1 can be easily recognized, so that the phase of the chain belt 1 in the front-back direction can be prevented from being generated. The reverse orientation (i.e., the orientation in which the upper leg portion 22 is in contact with the cloth 5) is sewed in the cloth 5. This effect is particularly important in the case where the chain belt 1 is subjected to color, printing, or the like, and the cloth 5 is used in the case where the product exhibits a specific design.

Further, in the first embodiment, the fastener element 20 and the fastener element 14 are integrally wound around the longitudinal direction of the zipper, and are sewn to the fabric 5 by the second sewing line 6. The second sewing line 6 straddles the second extending portion 23c of the leg portion 22 and the lower leg portion 23 of the fastener element 20, and pierces the fastener element 14 and the cloth 5 between the adjacent fastener elements 20. The chain belt 1 is sewn on the cloth 5.

In the first embodiment, as shown in Fig. 8, the chain belt 1 is sewn to the cloth 5 by the sewing machine 40 for sewing the chain tape in such a manner that the chain 1 is accommodated in the concave portion of the lower plate 42 of the sewing machine. The link attaching portion 5a (opposing side edge portion) in which the cloth 5 is disposed opposite to each other is disposed between the sewing machine upper plate 41 and the second extending portion 23c of the leg portion 23 below the fastener tape 1.

In this case, the sewing machine needle 43 is used as the sewing machine needle 43 by the sewing method of the lock stitching of the second sewing thread 6. The round end of the round needle is rounded to a spherical needle, and the diameter of the tip end thereof is preferably 0.2 mm or more and 0.6 mm or less.

Thus, by using the round head lancet, even if the sewing machine needle 43 collides with the fastener element 20 at the time of sewing, the position of the round burr can be punctured along the sprocket fixing member along the relative displacement of the fastener element 20 in the front-rear direction. Since the zipper is attached to the member (cloth) 5, damage to the fastener element 20 and breakage or bending of the sewing machine needle can be avoided, and the sewing step can be smoothly and stably performed.

Further, by using the lock type stitch as the stitch form of the second stitching line 6, the seam 6 of the second stitching line is not easily loosened and the strength is excellent, and further, even when sewing, the round head needle and the zipper chain are used. When the teeth 20 collide and the position of the round head needle (in other words, the position where the needle pierces the fastener element 14 and the cloth 5 is offset), the fastener tape 1 and the cloth 5 can be smoothly and stably stitched.

Furthermore, when such a sewing by the second sewing thread 6 is performed, the needle is pulled and pulled in the round head. In the case where the chain element 20 collides, in the chain belt 1 of the first embodiment, since the fastener element 20 is appropriately fixed to the element fixing member 14 as described above, the fastener element 20 can be allowed to avoid the round end. The manner of the lance is slightly moved, and unevenness in the distance between the fastener elements 20 held by the sprocket fixing member 14 can be prevented.

Further, in the present embodiment, the second sewing portion formed by the lock stitching of the second stitching line 6 (particularly, the portion of the second stitching line 6 exposed on the element row 11) is in the width direction of the slide fastener. It is disposed so as to overlap with the formation range of the first sewn portion formed by the double chain slit of the first sewn line 13. Here, the second sewn portion is located in the range in which the first sewn portion is formed, and is a chain of the first sewn portion formed on the front surface of the element row 11 (the upper surface of the leg portion 22 above the fastener element 20) In the range of the width direction of the cloth, the second sewing portion formed on the front surface of the element row 11 (the upper surface of the leg portion 22 above the fastener element 20) is disposed.

Further, the second sewing line 6 on which the second sewing portion is formed on the element row 11 is pierced by the fastener element 14 between the lower leg portions 23 of the adjacent fastener elements 20, and further, the adjacent fastener element 20 is passed. The cloth 5 is pierced between the upper legs 22 . In this case, a portion of the first sewing line 13 is also located between the second sewing line 6 and the upper surface of the leg portion 22 above the fastener element 20.

By performing the sewing step by the above-described fastener sewing machine 40, the fastener element 20, the fastener element 14 and the cloth 5 are one part of the second sewing line 6 which is sandwiched between the element rows 11. The sewing portion is sewn and fixed so as to be between the sewn portion and one of the second sewn lines 6 exposed on the front surface of the cloth 5. In this case, as described above, the second sewn portion of the second sewn line 6 is formed so as to overlap the first sewn portion of the first sewn line 13 so that the second sewn portion is mixed with the second sewn portion. 1 The sewing portion is not easily eye-catching, so that the appearance of the article to which the chain belt 1 is attached can be improved.

Further, in a state where the fastener tape 1 is fixed to the fabric 5, the second sewing portion of the second sewing thread 6 is formed on the front surface of the fastener element 20 together with the first sewing portion of the first sewing thread 13, and therefore The abrasion caused by the sliding of the sliding member 30 or the abrasion or collision caused by the external cause can be 1 Both the sewing part and the second sewing part are subjected to. Therefore, compared with the case where the second sewn portion and the first sewn portion are formed, it is possible to effectively prevent the first sewn line 13 and the second sewn line 6 from being broken or the like.

In the case where the second sewing portion of the second sewing line 6 is formed so as to overlap the first sewing portion of the first sewing line 13, the round needle is used as the sewing machine needle as described above. Thereby, the needle tip of the round burr can be sewn by the line between the stitches of the first stitching line 13, so that the cutting of the first stitching line 13 is less likely to occur during the sewing of the second stitching line 6. Further, in the present invention, as the stitch form of the second stitching line 6, a lock type stitch can be used.

As described above, after the pair of left and right fastener tapes 1 are sewn to the cloth (zipper-attached member) 5 of clothes or the like by the lock stitching of the second sewing thread 6, the fastener element rows 11 of the two fastener tapes 1 are 11 The slider 30 is slidably mounted. Further, the first stop and the second stop are formed so as to be adjacent to the front end and the rear end of the element row 11. Thereby, the zipper 3 of the zipper-free chain fabric of the first embodiment is formed.

Here, as shown in FIGS. 1 and 2, the slider 30 of the first embodiment has a slider main body 31 and a pull tab 32 having a mounting shaft portion at one end. Further, the slider main body 31 has an upper blade 33, a lower blade 34 disposed in parallel with the upper blade 33, and a guide post 35 connecting the front end portions (introduction port end portions) of the upper and lower blades 33 and 34. The upper flange 37 is erected from the left and right side edge portions of the upper blade 33 toward the lower blade 34, the protruding portion 36 disposed on the left and right side edge portions of the lower blade 34, and the upper blade 33 are disposed. The pull tab mounting portion 38 of the surface. Further, the upper blade 33 is provided with a partition portion 33a that is raised downward in the central portion of the upper blade 33 in the width direction.

At the front end portion of the slider main body 31, a guide post 35 is interposed therebetween, and a left and right introduction port is formed, and an end portion is formed at an end portion of the slider main body 31. Further, a sprocket guide path is formed between the upper and lower flaps 33 and 34, and the sprocket guide path is formed in a substantially Y shape so as to communicate the left and right introduction ports with the engagement opening, and the cloth 5 and the zipper are available. The sprocket teeth 20 are inserted together.

Further, although not shown, the first stopper is adjacent to the front end of the left and right element rows 11 so that the slider 30 does not come off from the front end side of the element row 11 at the front end of the element row 11. Installed on fabric 5. Further, at the rear end of the element row 11, the second stop is adjacent to the rear end of the left and right element rows 11 so as not to detach the slider 30 from the rear end side of the element row 11 and to straddle the left and right chains. The tooth row 11 is attached to the cloth 5.

Further, in the present invention, the method of attaching the first and second stoppers to the fabric 5 is not particularly limited. For example, the first and second stoppers may be fixed to the fabric 5 by welding or welding. The metal first and second stoppers may be plastically deformed by press working or the like to be fixed to the cloth 5. Further, for example, the second stopper may be formed by pressing and pressing the rear end portion of the element row 11 to be wide, or by sewing the end portion of the element row 11 so as to sew.

Further, in the first embodiment, as described above, after the pair of left and right fastener tapes 1 are sewn to the fabric 5, the slider 30 is attached to the element row 11 of the fastener tape 1, and the first stopper and the first stopper are provided. The 2 stop is attached to the cloth 5, thereby forming the zipper 3.

Further, in the garment 2 with the zipper 3 of the first embodiment, the step portion 23b is provided under the leg portion 23 of the fastener element 20, so that the cloth 5 is held by the accommodating space portion 25 of the fastener element 20. Inside, the thickness of the cloth 5 can be substantially absorbed. Thereby, the height dimension of the entire chain belt 1 and the height dimension A between the upper surface of the upper leg portion 22 and the lower surface of the first extending portion 23a of the lower leg portion 23 in the fastener element 20 are matched with each other. The thickness of 5 is independent of the fixed size.

Thereby, it is not necessary to prepare a plurality of kinds of sliders having different intervals between the upper and lower flaps 33, 34, for example, economical efficiency can be improved, and the chain belt 1 and the clothes 2 can be provided at low cost.

Further, when the slider 30 is slid and the left and right element rows 11 are opened and closed, the position of the upper surface of the leg portion 22 on the fastener element 20 in the vertical direction in the element guide path of the slider 30 is The position of the lower surface of the first extending portion 23a of the lower leg portion 23 is restricted by the lower surface of the partition portion 33a of the slider 30 and the upper surface of the lower wing plate 34. In the left-right direction, a plurality of zipper elements 20 The position of the joint portion 24 is restricted by the upper flange 37 of the slider 30 or the curved inner wall surface which becomes the boundary portion between the upper blade 33 and the upper flange 37. Therefore, the left and right fastener elements 20 can be effectively prevented from swaying in the element guide path of the slider 30, so that the meshing action or the separation operation of the left and right fastener elements 20 can be stably performed, so that the opening and closing of the zipper can be smoothly performed. operating.

Further, in the first embodiment, it is also possible to prevent the cloth 5 or the plurality of fastener elements 20 from being strongly pressed against the upper and lower flaps 33 and 34 of the slider 30 at the same time, or the fabric 5 bites into the slider 30. Therefore, the sliding operation of the slider 30 can be performed lightly and stably. Further, the problem that the first sewing line 13 or the second sewing line 6 is broken due to the friction between the fastener tape 1 and the slider 30 is less likely to occur.

Specifically, in the second embodiment, in the same manner as in the first embodiment, the chain belt 1 is aligned with the opening and closing portion of the cloth 7 (see FIG. 9), and the sewing machine 40 for sewing the belt is used, as shown in FIG. In the manner shown, the fastener tape 1 is sewn and fixed to the fabric 7 by the lock stitch of the second stitching line 6. Further, the element rows 11 of the fastener tapes 1 sewn to the right and left fabrics 7 are slidably mounted with the sliders 30 to form the first stop and the second stop so as to be adjacent to the front end and the rear end of the element rows 11 . Thereby, the garment 2a with the chain belt shown in Fig. 10 is manufactured.

In the garment 2a with the zipper 3a attached to the second embodiment of the present invention, since the fastener tape 1 is sewed on the relatively thin fabric 7, the chain tape is attached to the above-described embodiment 1 as shown in FIG. In comparison with the garment 2 (Fig. 2), the distance between the fabric 7 and the lower flap 34 of the slider 30 is slightly increased.

However, in the second embodiment, as in the first embodiment, the position of the upper surface of the leg portion 22 and the lower leg portion of the fastener element 20 in the vertical direction in the element guide path of the slider 30 are provided. The position of the lower surface of the first extending portion 23a of the second portion 23 is restricted by the lower surface of the partition portion 33a of the slider 30 and the upper surface of the lower wing plate 34, and in the left and right direction, a plurality of zipper elements 20 The position of the joint portion 24 is restricted by the upper flange 37 of the slider 30 or the curved inner wall surface which becomes the boundary portion between the upper flap 33 and the upper flange 37. Therefore, it is possible to effectively prevent the left and right fastener elements 20 from rattling in the element guide path of the slider 30.

Moreover, it is also possible to prevent the fabric 7 or the plurality of fastener elements 20 from being strongly pressed against the upper and lower flaps 33, 34 of the slider 30, or the fabric 7 to bite into the slider 30, so that the fabric can be carried out lightly and stably.
