Stop part for slide fastener and slide fastener having the same

Technical Field

The present invention relates to a stop and a slide fastener having the same. The stop portion is a front stop or a rear stop of a slide fastener in which linear elements of a disk type or a zigzag type made of synthetic resin are attached to one side edge of a fastener tape and a concealed slide fastener.

Background

Conventionally, various types of stop portions have been proposed for the stop portions of the front stop and the rear stop in the synthetic resin disc-shaped or zigzag-shaped linear slide fastener and the concealed slide fastener. For example, as shown in fig. 26, the stop portion 22 disclosed in japanese koku publication No. 56-51773: a synthetic resin sheet 21 having a circular cross section and formed so as to be fusible in a head 10 of a plurality of elements extending over a distal end portion of the linear element row 3 and located close to the back surface of the fastener tape; the end of the synthetic resin sheet 21 at the tip of the element row 3 is bent toward the surface, thereby forming a bent portion 21 a; the end surface of the bent portion 21a is lower than the surface of the element; the curved portion 21a is welded to a recessed engagement surface formed on a side surface of the element 10 at the end of the element row.

As shown in FIG. 27, the stop portion 23 disclosed in Japanese Kokoku publication Sho 59-25221: a synthetic resin film sheet 25 is placed on and welded to the upper side of a plurality of fastener elements in a linear fastener element row 3 made of synthetic resin, and a convex portion 25a is formed by making the film sheet 25 on the upper side of a sewing thread 24 for sewing a fastener element leg portion 11 thicker than the other portions, and the sewing thread 24 is protected by the convex portion 25a, and the portions other than the convex portion 25a are adhered in a state of being enclosed in the fastener elements.

As shown in FIG. 28, the stop portion 26 disclosed in Japanese Kokoku publication No. 51-4823: in a state where the disc-shaped or zigzag-shaped linear element rows 3 made of synthetic resin are engaged with each other, a metal headed pin 28 is inserted into a space 27 located on the back side of the plurality of element packets 10, thereby fixing the left and right elements.

End stop 22 shown in fig. 26: the synthetic resin sheet 21 is pressure-welded to the lower surface of the element 10 of the linear element row 3 by ultrasonic processing, and the distal end is bent toward the surface side of the element and welded to the side surface of the element 10. The synthetic resin sheet 21 is very troublesome to weld and cannot be produced at low cost. Since the synthetic resin sheet 21 is welded to the surface of the fastener element, peeling may occur during use.

In addition, the stop portion shown in fig. 27: the synthetic resin film sheet 25 is placed on the upper surfaces of the plurality of linear fastener elements, and ultrasonic processing is performed so that the surface of the front end stop 36 is convex. In this case, burrs may be generated at the end portions of the thin film pieces 25, which causes a problem in safety. The back stop 26 shown in fig. 28 is formed by inserting only a metal headed pin 28 into the linear element row 3 made of synthetic resin. Therefore, the fixation thereof is unstable, and when an excessive force is applied in use, there is a problem that the pin 28 is released.

Disclosure of Invention

The present invention has been made in view of the above problems, and an object of the present invention is to provide a stop portion of a slide fastener which is strong, excellent in quality, and can be manufactured at low cost, and another object of the present invention is to provide a stop portion of a slide fastener which can be manufactured easily and can exhibit an effective locking function. The present invention also provides a slide fastener having the stop, the slide fastener being formed of a fastener chain in which a special pattern or processing is applied to a fastener tape of a normal type or a concealed type slide fastener.

In order to achieve the above object, a 1 st basic configuration of the present invention is a fastener stop formed by welding a synthetic resin sheet fitted over a plurality of elements located at a distal end side of a linear element row made of synthetic resin attached to one side edge of a normal type or concealed type fastener tape.

The stop portion for a slide fastener is formed by attaching a linear element row made of synthetic resin to one side edge of a fastener tape, fitting a synthetic resin sheet along a plurality of elements located on a distal end side of the element row, and welding the elements. According to this configuration, since the synthetic resin sheet is fitted to the linear fastener element and then welded, the synthetic resin sheet can be held accurately at a predetermined position with respect to the linear fastener element, and can be welded efficiently.

Further, the synthetic resin sheet may be a rod-shaped body or a curved plate-shaped body, and by using such a rod-shaped body or a curved plate-shaped body, the synthetic resin sheet can be accurately and easily fitted and installed, and the synthetic resin sheet can be easily produced.

The rod-shaped body is inserted into the engagement space portion located on the back side of the engagement element packet of the linear fastener element and welded, whereby the above-described operational effects can be achieved, and the occurrence of burrs on the surface of the linear fastener element can be suppressed, and a stop portion having excellent quality can be formed.

Further, the engaging element package of the bar-shaped body and the linear element can be crushed and welded from the front surface and the back surface at the same time, and by performing such welding, the slider can be locked more reliably at the end of the linear element row, and the stopper portion that does not come loose can be formed.

The plate-like body is welded so as to cover the surfaces of the coupling head, leg portion, and connecting portion of the linear fastener element. By such measures, the occurrence of surface burrs of the linear fastener element can be suppressed, and a stop portion having excellent quality can be formed.

According to the present invention, the end stop can be formed by disposing the rod-shaped body inside the linear element rows in the non-engaged state and welding the rod-shaped body. In this case, the rod-shaped body can be easily inserted into the linear element row in the one-side element in which the elements are not engaged, and the front end stop can be easily produced.

Similarly, in the case of a plate-shaped body, the plate-shaped body is disposed on the surface of the linear element rows in a non-meshing state and welded, thereby forming the end stop. In this case, the plate-like body can be easily applied to the one-side element in which the element is not engaged, and the front end stop can be easily produced.

Further, the rear end stop can be formed by disposing and welding the rod-shaped body inside the linear element rows in the engaged state. Thus, the rod-shaped body can be easily applied to the fastener chain in which the fastener elements are engaged, and the back stop can be easily produced.

The plate can also be used to form the backstop. That is, the plate-like body is disposed on the surface of the linear element rows in the engaged state and welded to form the back stop. Thus, the plate-like body can be easily applied to the fastener chain in which the fastener elements are engaged, and the back stop can be easily manufactured.

In addition, the 2 nd basic configuration of the present invention is a slide fastener provided with the above-described stop, and the fastener tape of the fastener chain is subjected to a special processing, that is, an ink-jet pattern decoration and/or a water-repellent processing. According to this structure, the stop portion can be prevented from being damaged by being attached to the fastener tape, and the fastener can be made to have a very beautiful appearance.

Detailed Description

The stop portion of the slide fastener of the present invention will be specifically described below with reference to the drawings.

The slide fastener of the present invention is configured such that a monofilament of synthetic fiber such as polyamide or polyester is wound in a disc shape or bent in a zigzag shape to form a linear element row 3. The linear element rows 3 are sewn, woven or knitted into one side edge of the fastener tape by the sewing thread 8, thereby completing the manufacture of a normal type slide fastener or a concealed type slide fastener. The linear fastener element 3 in a disc shape or a zigzag shape is formed of a coupling head 10, upper and lower leg portions 11, a connecting portion 12, and a coupling space portion 13. The core thread 9 is inserted into the linear element row 3, and thereby the arrangement of the element row 3 to the fastener tape 4 and the engagement operation of the elements 3 can be stabilized.

The present invention is applicable to the stop portion 14 of the front stop 15 and the rear stop 16 of the concealed slide fastener as well as the above-described conventional slide fastener. The stop portion 14 of the front stop 15 of the conventional slide fastener shown in fig. 1 to 3 will be described. The fastener elements are sewn to one side edge of the fastener tape 4 so that the engaging element package 10 protrudes from the side edge, thereby forming the one-sided fastener elements 2 in which the core thread 9 is passed through the disc-shaped linear element row 3. A synthetic resin sheet 5 is inserted into a coupling space 13 formed on the back side of the coupling head 10 of the plurality of elements 3; the rod-like body 6 is set in a state of being held in the engagement space 13 surrounded by the fastener elements 3 and the core wires 9. The plurality of elements 3 are located at the end side of the one-side element 2. The synthetic resin sheet 5 is a rod-shaped body 6 formed in a round bar shape using a thermoplastic resin such as polyamide or polyester or a resin having a low melting point, which is the same as the fastener elements 3.

The rod-shaped body 6 provided in the engagement space portion 13 can be welded to the fastener element 3 and the core wire 9 by ultrasonic welding. Therefore, since the coupling space portion 13 located on the back side of the coupling element packet 10 of the element 3 is locked by the welded synthetic resin sheet 5, the coupling element packet 10 of the element 3 to be coupled can be inserted into the coupling space portion 13 and coupled, a locking function as a stopper portion of the front stopper 15 for preventing the release of the slider from the fastener chain 1 can be exhibited.

Since the rod-like bodies 6 of the synthetic resin sheet 5 are welded to the disc-like fastener elements 3, the fastener elements 3 can be formed to have excellent quality end stops 15 without burrs on the surfaces thereof. The size and shape of the rod-like body 6 to be used can be selected according to the size of the fastener element 3 to be used and the shape of the engagement space 13.

The stop 14 shown in FIGS. 4 to 6 is a front stop 15 of the concealed slide fastener. The core thread 9 is passed through the elements in the disc-shaped linear element row 3, and sewn to the fastener tape 4 through the leg portions 11, so that the coupling portions 12 of the elements 3 are located on the side edge side of the fastener tape 4. The fastener tape 4 is folded back in the vicinity of the sewing line 8 positioned on the inner side of the fastener tape 4, and the coupling head 10 is formed in a shape protruding from the folded-back portion 17, thereby completing the production of the concealed one-side element 2. The rod-like body 6 of the synthetic resin sheet 5 is inserted into and fitted into the coupling space 13 located on the back side of the coupling head 10 of the plurality of elements 3, the elements 3 being located on the distal end side of the one-side element 2.

The rod-shaped body 6 fitted in the engagement space portion 13 is welded to the fastener elements 3 and the core wires 9 by ultrasonic welding. Therefore, the coupling space portion 13 located on the back side of the coupling element package 10 is locked by the synthetic resin sheet 5, similarly to the normal type element rows 3, so that the coupling element packages 10 of the coupling elements 3 as the coupling objects cannot be coupled with each other, and the locking function of the stop portion as the front stop 15 of the concealed slide fastener can be exhibited.

In particular, since the element row 3 of the concealed slide fastener is positioned on the back side of the one-side element 2, the front end stop 15 is also positioned on the back side, and when a burr is present on the front end stop 15, the burr is likely to come into direct contact with the skin of the neck portion or the like, and it is necessary to completely prevent the burr from being generated. In contrast, in the top end stop 15 of the present invention, since the rod-like bodies 6 as the synthetic resin sheet 5 are inserted into the element rows 3 and welded therein, no burrs are generated on the surfaces of the element rows 3, and a concealed slide fastener with excellent quality can be manufactured. In addition, since the shape of the stopper portion 14 is not changed, when the concealed slide fastener is sewn to clothes or the like, the defect that the stopper portion abuts against the presser foot guide of the sewing machine does not occur.

In the fastener chain 1 in which the disc-shaped element rows 3 provided on the side edges of the right and left fastener tapes 4 are engaged with each other, as shown in fig. 7 and 8, the stopper portion 14 of the normal type fastener chain is formed by inserting, holding, and fitting the rod-shaped body 6 in the form of a round bar formed of the synthetic resin sheet 5 into the engagement space portion 13, the engagement space portion 13 being located on the back side of the engagement element pocket 10 of the plurality of elements 3 on the distal end side of the fastener chain 1; thereafter, the fastener elements 3 and the core wires 9 are fixed by welding by ultrasonic welding, thereby completing the stop portion 14 as the rear stop 16 of the normal type slide fastener.

In the fastener chain 1 in which the disc-shaped linear element rows 3 provided in the folded-back portions 17 of the right and left fastener tapes 4 are engaged with each other, as shown in fig. 9, the stopper portion 14 of the concealed fastener chain is formed by inserting, holding, and fitting the bar-shaped body 6 as the synthetic resin sheet 5 into the engagement space portion 13, the engagement space portion 13 being located on the back side of the engagement element pocket 10 of the plurality of elements 3 on the distal end side of the fastener chain 1; thereafter, the fastener elements 3 and the core wires 9 are fixed by welding by ultrasonic welding, thereby completing the stop portion 14 as the back stop 16 of the concealed slide fastener.

In the stop portion 14 of the concealed slide fastener shown in fig. 10, the rod-like body 6 of the synthetic resin sheet 5 passed through, held and fitted in the coupling space portion 13 located on the back side of the coupling element package 10 of the element row 3 provided on the folded-back portion 17 of the fastener tape 4 of the one-sided element 2 is welded to the element row 3 and the core thread 9 by ultrasonic welding; simultaneously, the engaging tooth packet 10 of the element row 3 is pressed from the top and bottom, i.e., the outside and the inside, and the rod-like body 6 is flattened and fixed to form a front stop 15; by increasing the lateral width of the stopper portion 14 of the element row 3, the locking function of the slider can be reliably realized. This type of stop 14 can be applied to the back stop 16 of the fastener chain 1, and can also be applied to a normal type slide fastener.

The stopper of the slide fastener of each of the embodiments described above uses the rod-like body 6 of the synthetic resin sheet 5 as a base material constituting the stopper 14; however, the synthetic resin sheet 5 used for the stop 14 of the slide fastener of each of the following embodiments is: a pipe formed of a thermoplastic resin such as polyamide or polyester or a resin having a low melting point is cut from one side and then expanded to form a bent plate-like body 7.

The stop portion 14 of the front stop 15 of the conventional slide fastener shown in fig. 11 to 13 is sewn to one side edge of the fastener tape 4 by passing the core thread 9 through the element in the disc-shaped element row 3 in a state where the coupling element package 10 protrudes from the side edge, thereby producing the one-sided element 2. Coupling the coupling head 10, the leg portion 11, and the coupling portion 12, which are exposed portions of the fastener tape 4 of the plurality of element rows 3 located on the distal end side of the one-side element 2, in a state of being surrounded and covered by the synthetic resin sheet 5 in a bent shape; thereafter, the synthetic resin sheet 5 is welded and fixed to the element row 3 by ultrasonic welding, and the coupling element 10 of the element 3 to be coupled cannot be inserted into the coupling space portion 13 to be coupled, so that the front end stop 15 for preventing the slider from coming off is formed. Further, by increasing the thickness of the synthetic resin sheet 5, the synthetic resin sheet 5 is brought into contact with the guide posts of the slider, and a front stop 15 for preventing the slider from coming loose is formed.

In the stop portion 14 of the front stop 15 of the concealed slide fastener shown in fig. 14 to 16: the core thread 9 is passed through the elements in the disc-shaped linear element row 3, and the leg portion 11 is sewn to the fastener tape 4 by the sewing thread 8 in a form in which the coupling portion 12 of the element 3 is positioned on the side edge side of the fastener tape 4. The fastener tape 4 is folded back in the vicinity of the sewing line 8 positioned on the inner side of the fastener tape 4, and the coupling head 10 is formed in a shape protruding from the folded-back portion 17, thereby completing the production of the concealed one-side element 2. Engaging the coupling element package 10, the leg portion 11, and the connecting portion 12 exposed to the plurality of element rows 3 located on the distal end side of the one-side element 2 in a state of being surrounded and covered by the synthetic resin sheet 5 in a bent shape; thereafter, the synthetic resin sheet 5 is welded and fixed to the element row 3 by ultrasonic welding, and the coupling element package 10 of the element 3 to be coupled cannot be inserted into the coupling space portion 13 to be coupled, so that the front end stop 15 for preventing the slider from coming loose is formed. Further, by increasing the thickness of the synthetic resin sheet 5, the synthetic resin sheet 5 is brought into contact with the guide posts of the slider, and a front stop 15 for preventing the slider from coming loose is formed.

In the stop portion 14 of the normal type slide fastener shown in fig. 17 and 18, in the fastener chain 1 in a state in which the disk-shaped element rows 3 provided on the side edges of the right and left fastener tapes 4 are engaged with each other, the engaging element package 10, the leg portion 11, and the connecting portion 12 of the plurality of elements 3 exposed on the distal end side of the fastener chain 1 are engaged with each other in a state in which they are surrounded and covered by the synthetic resin sheet 5 in a curved shape; thereafter, the synthetic resin sheet 5 is fixed to the element 3 by welding by ultrasonic welding, thereby completing the stop portion 14 as the back stop 16 of the normal type slide fastener.

In the fastener chain 1 in which the disc-shaped element rows 3 provided in the folded-back portions 17 of the right and left fastener tapes 4 are engaged with each other, the coupling head 10, the leg portion 11, and the coupling portion 12 of the plurality of elements 3 exposed on the distal end side of the fastener chain 1 are engaged with each other in a state surrounded and covered by the synthetic resin sheet 5 in a curved shape in the stop portion 14 of the concealed slide fastener shown in fig. 19 and 20; thereafter, the synthetic resin sheet 5 is fixed to the element 3 by welding by ultrasonic welding, thereby completing the stop portion 14 as the rear stop 16 of the concealed slide fastener.

In the present invention, the bar-shaped body 6 of the synthetic resin sheet 5 is inserted and fitted into the engagement space 13 of the linear element row 3, and the plate-shaped body 7 of the synthetic resin sheet 5 is fitted so as to cover the surface of the linear element row 3, and the bar-shaped body 6 and the plate-shaped body 7 are used; thereafter, the rod-shaped body 6 and the plate-shaped body 7 are welded to the linear element rows 3 by ultrasonic welding, whereby the end stop portions 14 of the front end stop 15 and the rear end stop 16 of the normal slide fastener and the concealed slide fastener can be formed firmly.

Finally, an example of the slide fastener shown in FIGS. 21 to 25 will be explained. The slide fastener shown here is a general type slide fastener, and various patterns, characters, and the like are expressed on the fastener tape 4 positioned on the surface side a of the fastener chain 1 by ink jet as a special processing, or the fastener tape 4 is subjected to a waterproof processing. A core thread 9 is attached to a synthetic resin disc-shaped or zigzag linear element row 3, and the element row 3 is sewn to a fastener tape 4 positioned on the back surface side B of the fastener chain 1 by a sewing thread 8 and attached to the fastener tape edge portion, thereby completing the fastener chain 1.

As shown in fig. 22 and 23, the fastener 1 is configured such that the rod-like body 6 as the synthetic resin sheet 5 is inserted through the plurality of fastener elements 3 and fitted into the coupling space portion 13 located on the back side of the coupling element pocket 10 of the fastener elements 3 on both sides, and the plurality of fastener elements 3 are located on the distal end side of the fastener element rows 3 arranged on the back surface side B and coupled with each other; thereafter, the end stop portion 14 of the rear end stop 16 is welded and fixed by ultrasonic welding. This type of stop 14 can also be used for the front stop 15 at the upper end of the one-sided element 2.

As shown in fig. 24 and 25, the coupling head 10, the leg portion 11, and the coupling portion 12 appearing on the fastener tape 4 of the plurality of elements 3 are engaged in a state of being surrounded and covered by the plate-like body 7 of the bent synthetic resin sheet 5, the plurality of elements 3 being positioned on the distal end side of the element row 3 which is disposed on the back surface side B of the fastener chain 1 and which is engaged with each other; thereafter, the plate-like body 7 is welded and fixed to the element row 3 by ultrasonic welding, thereby producing the end stop portion 14 of the end stop 16. This type of stop 14 can also be used for the front stop 15 at the upper end of the one-sided element 2.

The fastener chain 1 including the above-described stopper portion 14 does not have a trace of the stopper portion 14 exposed from the fastener tape 4 on the front surface side a, and therefore, the fastener chain 1 having a good appearance can be completed. The fastener tape 4 is subjected to the special processing of the fastener chain 1, and the fastener chain 1 can be applied not only to a general type fastener chain 1 but also to a concealed type fastener chain 1, thereby producing a concealed type fastener having a good appearance.
