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 fabric bodies 10 arranged side by side, two support members 20, a fixing member 40, a slider 50 and a plurality of chain teeth 30. The two support members 20 are respectively arranged along the edge of each fabric body 10 and are located directly above the edge; the plurality of chain teeth 30 are arranged in sequence along the length direction of each support member 20; the fixing member 40 has a plurality of sewing parts, which are sewn to the fabric body 10 at the positions on both sides of the support member 20 in close contact with the edges of the chain teeth 30, so as to fix the support member 20 to the fabric body 10; the slider 50 cooperates with the chain teeth 30 on both sides, and is used to bite and separate the two fabric bodies 10.

[0040] It should be noted that the fixing member 40 is a sewing thread, but is not limited to a sewing thread. The present application arranges the chain elements 30 through the support member 20, and the support member 20 is placed on the edge of the fabric body 10, and then fixed to the fabric through the sewing thread. The sewing thread is tightly sewn around the edge of the chain element 30, which improves the sewing beauty and the bonding strength of a single chain element 30 and a chain of chain elements 30; at the same time, the sewing thread surrounds the support member 20 and pierces and is fixed to the fabric body 10 on both sides of the support member 20, which ensures the stability of the support member 20, thereby effectively improving the sewing stability of the zipper.

[0041] In order to prevent the fixing member 40 from interfering with the movement of the slider 50 when the slider 50 is pulled, the slider 50 may adopt a base without a lower baffle.

[0042] At the same time, due to the "hidden" stitching, the appearance of the zipper after sewing appears to have only the chain elements 30, making it lightweight.

[0043] In some embodiments of the present application, the fabric body 10 is provided with a first puncture hole 11, a second puncture hole 12, a third puncture hole 13 and a fourth puncture hole 14 at intervals near the edge of each chain tooth 30. The first puncture hole 11 and the fourth puncture hole 14 are respectively located on both sides of the chain tooth 30 along the length direction of the fabric body 10; the second puncture hole 12 is arranged corresponding to the first puncture hole 11, and are respectively located on both sides of the support member 20, and the fourth puncture hole 14 is arranged corresponding to the third puncture hole 13, and are respectively located on both sides of the support member 20, and the sewing part is sewn in the first puncture hole 11, the second puncture hole 12, the third puncture hole 13 and the fourth puncture hole 14 close to the edge of the chain tooth 30 to fix the support member 20 to the fabric body 10.

[0044] Specifically, the first piercing hole 11 and the fourth piercing hole 14 are respectively located on both sides of the middle of the fastener element 30 , and the second piercing hole 12 and the third piercing hole 13 are respectively located on both sides of the rear edge of the fastener element 30 .

[0045] Furthermore, the first puncture hole 11 and the second puncture hole 12, as well as the third puncture hole 13 and the fourth puncture hole 14 are respectively opened on both sides of the support member 20, so that the fabric body 10 and the support member 20 are sewn closer, thereby reducing the exposure of the chain teeth 30 on the back of the zipper, refer to the attached Figure 4 The fabric body 10 can directly fit the human body and play the role of the inner placket, that is, the inner placket structure of the clothes can be integrated into the connection structure between the fabric body 10 and the chain tooth 30, thereby simplifying the structure of the clothes.

[0046] It should be noted that the present application does not limit the sewing route of the sewing portion, and at the same time, the relative positions of the first puncture hole 11, the second puncture hole 12, the third puncture hole 13 and the fourth puncture hole 14 are not limited.

[0047] In some embodiments of the present application, the sewing portion includes an upper thread and a lower thread, and the upper thread and the lower thread are respectively located on the top and the bottom of the support member 20, and the upper thread and the lower thread are respectively close to the edge of the chain tooth 30 and intertwined with each other in the first puncture hole 11, the second puncture hole 12, the third puncture hole 13 and the fourth puncture hole 14.

[0048] That is, the first piercing hole 11, the second piercing hole 12, the third piercing hole 13 and the fourth piercing hole 14 are used for the cross fixing of the upper thread and the lower thread, so that the upper thread and the lower thread wrap and fix the support member 20, and then fix the fastener element 30 on the fabric body 10. It should be noted that the sewing shapes of the upper thread and the lower thread may be consistent or inconsistent.

[0049] In some embodiments of the present application, the upper line and / or lower line include a first line 41, a second line 42 and a third line 43. The first line 41 is formed by the upper line or the lower line running from the first puncture hole 11 along the edge of the chain element 30 to the second puncture hole 12; the second line 42 is formed by the upper line or the lower line running from the second puncture hole 12 along the edge of the chain element 30 to the third puncture hole 13; the third line 43 is formed by the upper line or the lower line running from the third puncture hole 13 along the edge of the chain element 30 to the fourth puncture hole 14.

[0050] Specifically, the fixing member 40 is sewn along the edge of each of the fastener teeth 30 in the gap between the fastener teeth 30 rows, and the sewing path of the front and back sides is the same, so as to achieve the horizontal fixing of the fastener teeth 30 rows. The fixing member 40 is sewn in a straight line along the tail edge of each of the fastener teeth 30 rows in the longitudinal direction of the fastener teeth 30 rows, so as to achieve the longitudinal fixing of the fastener teeth 30 rows.

[0051] In some embodiments of the present application, the fixing member 40 further includes a plurality of connecting portions 44, each connecting two adjacent sewing portions.

[0052] Specifically, the connecting portion 44 is located between two adjacent sewing portions, and is linearly sewn and fixed on the fabric body 10 along the length direction of the support member 20, so as to connect the two adjacent sewing portions. In other words, the first routing line 41 of one sewing portion is connected to the third routing line 43 of the other sewing portion through the connecting portion 44.

[0053] It should be noted that the first wiring 41, the second wiring 42, the third wiring 43 and the connecting portion 44 can be a continuous sewing line. Figure 1 The fixing member 40 is continuously sewn in a bow shape from top to bottom or from bottom to top along the length direction of the supporting member 20 alternately at the positions of the fabric body 10 on both sides of the supporting member 20. The sewing method is simple and efficient, and does not require the use of special sewing equipment.

[0054] In some embodiments of the present application, the edge of the fabric body 10 is formed by folding back the side edge of the fabric body 10 toward the width direction of the fastener element 30 .

[0055] It should be noted that the fabric body 10 can be a placket of a garment, such as Figure 6 As shown, the chain element 30 is sewn to the clothing placket through sewing lines, and then the chain element 30 is engaged and separated by the pull head 50. Specifically, the support member 20 is located directly above the edge of the fabric body 10, 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.

[0056] In some embodiments of the present application, an upper stop and a lower stop are also included. The upper stop and the lower stop are respectively arranged at the two ends of the support member 20 and are spaced apart from the chain teeth 30. The fixing member 40 is sewn to the edges of the upper stop and the lower stop at the parts of the fabric body 10 located on both sides of the support member 20.

[0057] It should be noted that the present application does not limit the shape and size of the upper stopper and the lower stopper.

[0058] In some embodiments of the present application, the support member 20 is cylindrical, and the chain element 30 is fixed to the support member 20 by injection molding.

[0059] Specifically, the support member 20 is a ribbed cylindrical strip, the length of which is consistent with the fabric body 10, and is arranged parallel to the fabric body 10, and is sequentially penetrated by the main body 31 of multiple chain teeth 30. Of course, the present application does not limit the shape and size of the support member 20, and can be set according to actual needs.

[0060] In some embodiments of the present application, the fastener 30 includes a main body 31 and an engagement portion 32. The main body 31 is disposed on the support 20, and its bottom is closely attached to the top of the edge; the engagement portion 32 is disposed on the side of the main body 31 away from the fabric body 10.

[0061] Specifically, the main body 31 is rectangular, the meshing portion 32 extends to the outside of the fabric body 10 along the width direction of the main body 31, and the two sides of the meshing portion 32 are waisted, that is, the width in the middle of the meshing portion 32 is smaller than the width at both ends, so as to allow the tops of the chain teeth 30 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 30.

[0062] The present application also provides a fabric comprising the above-mentioned zipper.

[0063] 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.

[0064] 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.

[0065] 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.
