DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] The present application provides a zipper, comprising two pieces of fabric tapes 10 arranged side by side, and also comprising a plurality of chain teeth 20, a fabric body 30, a fixing member 40 and a pull head 50. Among them, the plurality of chain teeth 20 are sequentially arranged on one side of the fabric tape 10 along the length direction of the fabric tape 10; the fabric body 30 covers the other side of the fabric tape 10; the fixing member 40 sequentially and alternately pierces the portion of the fabric tape 10 close to the chain teeth 20 and the portion of the fabric body 30 located outside the fabric tape 10 along the length direction of the fabric tape 10, so as to fix the fabric tape 10 to the fabric body 30; the pull head 50 cooperates with the chain teeth 20 on both sides, and is used to bite and separate the two fabric tapes 10.

[0040] It should be noted that the above-mentioned fixing member 40 is a sewing thread, but is not limited to a sewing thread. In the present application, the chain teeth 20 are arranged by means of a cloth tape 10, and then the cloth tape 10 is directly sewn to the fabric body 30 by means of a sewing thread. In order to enhance the sewing strength of the zipper, the sewing thread is alternately pierced through the cloth tape 10 and the fabric body 30 in sequence. At the same time, in order to enhance the fit between the zipper and the garment, the exposure of the cloth tape 10 is minimized, the piercing point of the sewing thread is set at the position where the cloth tape 10 is close to the chain teeth 20, and the fabric body 30 is covered on the upper surface of the cloth tape 10 where the chain teeth 20 are not provided, so as to achieve the effect of no cloth tape 10, thereby improving the aesthetics of the zipper sewing.

[0041] In some embodiments of the present application, the zipper further includes a plurality of first puncture holes 11 and a plurality of second puncture holes 31. Among them, the plurality of first puncture holes 11 are provided at the portion of the tape 10 close to the chain element 20, and are spaced apart along the length direction of the tape 10; the plurality of second puncture holes 31 are provided at the portion of the fabric body 30 located outside the tape 10, and are spaced apart along the length direction of the tape 10, all the second puncture holes 31 are arranged in a staggered manner with all the first puncture holes 11, and the fixing member 40 is alternately provided at the first puncture holes 11 and the second puncture holes 31 in sequence along the length direction of the tape 10, so as to fix the tape 10 to the fabric body 30.

[0042] Specifically, the first puncture hole 11 on the cloth tape 10 is opened at a position close to the chain element 20 and close to the fabric body 30. In this way, the fixing member 40 fixes the cloth tape 10 and surrounds the folded part of the fabric body 30, playing the role of fixing the side material, preventing the side material from tilting or moving too much to expose the cloth tape 10, achieving the effect of no cloth tape 10 while ensuring the stability of the folded part of the fabric body 30. At the same time, combined with the narrow edge characteristics of the narrow edge cloth tape 10, the second puncture hole 31 on the fabric body 30 is set on the outside of the cloth tape 10, ensuring the sewing connection effect of the cloth tape 10 and the fabric body 30, and cooperating with the narrow edge cloth tape 10 to achieve lightweight clothing.

[0043] Furthermore, with Figure 1 With the orientation as a reference, the fixing member 40 pierces the first piercing holes 11 and the second piercing holes 31 alternately from top to bottom or from bottom to top. It should be noted that the present application does not limit the sewing route of the fixing member 40, that is, the arrangement of all the second piercing holes 31 and all the first piercing holes 11 is not limited, and all the second piercing holes 31 and all the first piercing holes 11 can be set one-to-one.

[0044] In some embodiments of the present application, the fixing member 40 includes an upper sewing thread and a lower sewing thread 44 that are interwoven with each other through all the first puncture holes 11 and all the second puncture holes 31 .

[0045] That is to say, all the first puncture holes 11 and all the second puncture holes 31 are used for cross-fixation of the upper sewing thread and the lower sewing thread 44. Specifically, the upper sewing thread is located on the upper surface of the fabric body 30, and the lower sewing thread 44 is located on the lower surface of the fabric body 30. The sewing shapes of the upper sewing thread and the lower sewing thread 44 can be consistent or inconsistent. The upper sewing thread and the lower sewing thread 44 alternately pass through the first puncture holes 11 and the second puncture holes 31 and interweave with each other. In this way, the upper sewing thread and the lower sewing thread 44 wrap and fix the cloth tape 10 and the fabric body 30 together, and then fix the chain element 20 on the fabric body 30.

[0046] In some embodiments of the present application, the sewing upper line includes an exposed portion 41, which is formed by the sewing upper line running alternately from the first puncture hole 11 to the second puncture hole 31 and from the second puncture hole 31 to the first puncture hole 11 along the length direction of the cloth tape 10, and is located at the top of the fabric body 30.

[0047] Specifically, the exposed portion 41 is threaded and alternately runs from the first puncture hole 11 to the second puncture hole 31 , and from the second puncture hole 31 to the first puncture hole 11 in sequence along the length direction of the cloth tape 10 .

[0048] In some embodiments of the present application, the sewing upper thread further includes a first extension portion 42 and a second extension portion 43. The first extension portion 42 is connected to the exposed portion 41, and is formed by the sewing upper thread extending from the first puncture hole 11 along the width direction of the cloth tape 10 close to the second puncture hole 31, and is located at the bottom of the fabric body 30; the second extension portion 43 is connected to the exposed portion 41, and is formed by the sewing upper thread extending from the second puncture hole 31 along the width direction of the cloth tape 10 close to the first puncture hole 11, and is located at the bottom of the fabric body 30; the sewing lower thread 44 is spirally arranged along the length direction of the cloth tape 10, and is alternately interwoven with the first extension portion 42 and the second extension portion 43 in sequence.

[0049] Specifically, the exposed portion 41 and the first extension portion 42 and the second extension portion 43 are the same sewing line. That is, the sewing upper line passes through the first puncture hole 11 from the upper surface of the tape 10 and extends along the width direction of the tape 10 close to the second puncture hole 31, then interweaves with the sewing lower line 44, returns to the first puncture hole 11 and extends from the lower surface of the tape 10, then goes to the adjacent second puncture hole 31, then passes through the second puncture hole 31 and extends along the width direction of the tape 10 close to the first puncture hole 11, then interweaves with the sewing lower line 44, and finally returns to the second puncture hole 31 and extends from the lower surface of the tape 10, and the cycle is repeated alternately.

[0050] In some embodiments of the present application, the portion of the fabric body 30 covering the tape 10 is formed by folding the side edge of the fabric body 30 back toward the width direction of the tape 10 .

[0051] It should be noted that the fabric body 30 can be a placket of a garment, such as Figure 4 As shown, the chain element 20 is sewn to the clothing placket through sewing lines, and then the chain element 20 is engaged and separated by the pull head 50. Specifically, the edge of the fabric body 30 covers the portion of the upper surface of the tape 10 where the chain element 20 is not provided, and the edge is formed by folding the cut end of the clothing placket back into a U shape along its length direction. In this way, the edge is thicker than other parts of the clothing, thereby improving the strength of the edge and increasing the stability of the zipper when in use.

[0052] In some embodiments of the present application, the zipper further includes a rib 60 , which is disposed on one side of the fabric tape 10 along the length direction of the fabric tape 10 , and all the chain elements 20 are sequentially mounted on the rib 60 .

[0053] Specifically, the belt rib 60 and the fabric tape 10 are an integrally formed structure, and the belt rib 60 is a reinforced portion of the edge of the fabric tape 10 for supporting the metal or plastic fastener elements 20 .

[0054] In some embodiments of the present application, the rib 60 is cylindrical, and the fastener element 20 is fixed to the rib 60 by injection molding.

[0055] Specifically, the ribs 60 are cylindrical strips, the length of which is consistent with the fabric body 30, and are arranged parallel to the fabric body 30, and are sequentially passed through the main body 21 of multiple fastener teeth 20. Of course, the present application does not limit the shape and size of the ribs 60, and can be set according to actual needs.

[0056] In some embodiments of the present application, the fastener 20 includes a main body 21 and an engaging portion 22. The main body 21 is mounted on the rib 60; the engaging portion 22 is disposed on a side of the main body 21 away from the fabric body 30.

[0057] Specifically, the main body 21 is rectangular, the meshing portion 22 extends to the outside of the fabric body 30 along the width direction of the main body 21, and the two sides of the meshing portion 22 are waisted, that is, the width in the middle of the meshing portion 22 is smaller than the width at both ends, so as to allow the tops of the chain teeth 20 on the adjacent two sides to be inserted to achieve meshing. It should be noted that the present application does not limit the shape and size of the chain teeth 20.

[0058] The present application also provides a fabric comprising the above-mentioned zipper.

[0059] It should be noted that the above fabric can be bags, clothing, shoes and hats, but is not limited to clothing, bags, shoes and hats, and can also be other daily necessities with the above zipper.

[0060] It should be noted that the above sewing method can be applied to the sewing and fixing of upper and lower stops and square latches in addition to fixing the chain elements 20 .

[0061] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0062] Specific examples are used herein to illustrate the principles and implementation methods of the present application, and the description of the above embodiments is only used to help understand the method and core ideas of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
