Description

Technical Field

[0001] This application relates to the field of clothing accessories, specifically to a zipper and fabric. Background Technology

[0002] Zippers are widely used in clothing, bags, and shoes. Currently, as people further pursue lightweight and soft clothing, they consider the structure and functionality of accessories when choosing clothing. A typical zipper package usually includes a fabric tape, reinforcing strip, and teeth. Among them, the fabric tape has a certain weight, which makes it difficult to meet the requirements of lightweighting. At the same time, the fabric tape is usually exposed, and if there is a color difference between the fabric tape and the clothing fabric, it will affect its aesthetics.

[0003] The prior art (CN107898067B) discloses a product with a zipper. The zipper uses a non-woven fabric sewing method, which solves the problem of weight reduction. However, because the sewing path is far away from the zipper teeth, the sewing and piercing parts are too obvious. At the same time, when the zipper head slides, it is easy to come into contact with and wear the sewing, thus greatly reducing its performance.

[0004] In conclusion, how to reduce the exposure of sewing threads while improving the reliability of zipper sewing is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this application is to provide a zipper and fabric that reduce the exposure of seams and improve their stability in use.

[0006] To achieve the above objectives, this application provides a zipper comprising two side-by-side fabric bodies, and further comprising:

[0007] Two support members are respectively arranged parallel to each other along the edges of the two fabric bodies that are close to each other;

[0008] Multiple chain teeth are arranged sequentially along the length of each of the support members, with one side being adjacent to the edge;

[0009] A fastener, located at the edge, has multiple sequentially connected sewn portions, which are cross-wound around the support between two adjacent chain teeth, for fixing the chain teeth to the fabric body;

[0010] The pull tab engages with the chain teeth on both sides to engage and disengage the two fabric bodies.

[0011] Preferably, the sewing part includes an upper thread and a lower thread, which are respectively intersecting and located on the top and bottom of the support member. The upper thread and the lower thread are interwoven on the support member and the edge to fix the chain teeth to the fabric body.

[0012] Preferably, the portion of the edge located between two adjacent chain teeth is provided with a first piercing hole and a second piercing hole at intervals along the length direction of the edge, and the upper wire and the lower wire intertwine with each other on the edge through the first piercing hole and the second piercing hole.

[0013] Preferably, the upper thread and the lower thread are interwoven on the side of the support member opposite to the main body of the fabric.

[0014] Preferably, the upper limit and / or the lower limit include:

[0015] The first routing is formed by the upper or lower routing from the first piercing hole along the side of one of the chain teeth to the side surface;

[0016] The second routing line is formed by the upper or lower line running from the side of the support member in a direction inclined relative to the length direction of the support member to the second piercing hole;

[0017] The third trace is formed by the upper or lower trace running from the second piercing hole along the edge to the first piercing hole;

[0018] The fourth routing line is formed by the upper or lower line running from the first piercing hole along a direction inclined relative to the length direction of the support member to the side surface;

[0019] The fifth routing line is formed by the upper or lower line running from the side along the side of another chain tooth to the second piercing hole.

[0020] Preferably, the support member has a third piercing hole and a fourth piercing hole spaced apart along its length at one end away from the edge, wherein the third piercing hole is provided corresponding to the first piercing hole and the fourth piercing hole is provided corresponding to the second piercing hole, and the upper wire and the lower wire are intertwined on the support member through the third piercing hole and the fourth piercing hole.

[0021] Preferably, the upper limit and / or the lower limit include:

[0022] The first routing line is formed by the upper or lower line running from the first piercing hole along a direction inclined relative to the length direction of the support member to the fourth piercing hole;

Detailed Implementation

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] This application provides a zipper, including two fabric bodies 10 arranged side by side, two support members 20, multiple zipper teeth 30, a fixing member 40, and a zipper pull 50. The two support members 20 are arranged parallel to each other along the edges of the two fabric bodies 10 that are close to each other; the multiple zipper teeth 30 are arranged sequentially along the length of each support member 20, with one side adjacent to the edge; the fixing member 40 is located at the edge and has multiple sequentially connected sewn portions 41, which cross and wrap around the support member 20 between adjacent zipper teeth 30 to fix the zipper teeth 30 to the fabric bodies 10; the zipper pull 50 cooperates with the zipper teeth 30 on both sides to engage and disengage the two fabric bodies 10.

[0045] It should be noted that the aforementioned fastener 40 is a sewing thread, but is not limited to sewing thread. In this application, the chain teeth 30 are arranged by the support member 20 and then directly sewn onto the fabric body 10 by the sewing thread.

[0046] Specifically, with attachment Figure 1With the orientation as a reference, the sewing thread is attached to the side edge of the chain tooth 30 and is "crossed" in the gap between two adjacent chain teeth 30. The sewing path is the same on both sides to achieve the fixation of the chain tooth 30 in the horizontal direction. The sewing thread is attached to the tail edge of the chain tooth 30 and is straight in the fabric body 10 to achieve the fixation of the chain tooth 30 in the vertical direction.

[0047] In this way, the above-mentioned stitching paths are all sewn close to the edge of the chain tooth 30, so that the sewing thread is not obviously exposed after sewing, and also avoids the shaking of a single chain tooth 30 in any direction.

[0048] It should be noted that the main fabric 10 can be the placket of the garment, such as... Figure 4 As shown, the zipper teeth 30 are sewn to the garment placket with stitching, and then engaged and disengaged by the zipper pull 50. The edge of the fabric body 10 is formed by folding back into a U-shape from the cut end of the garment placket along its length. This makes the edge of the fabric body 10 thicker than other parts of the garment, increasing edge strength and enhancing the stability of the zipper during use.

[0049] In some embodiments of this application, the sewing part 41 includes an upper thread and a lower thread, which are respectively intersecting and located on the top and bottom of the support member 20. The upper thread and the lower thread are interwoven on the support member 20 and the edge to fix the chain teeth 30 to the fabric body 10.

[0050] It should be noted that, in addition to fixing the chain teeth 30, the above sewing method can also be applied to the sewing and fixing of the upper and lower stops and the square pins.

[0051] In some embodiments of this application, the edge of the fabric body 10 is provided with a first piercing hole and a second piercing hole at intervals along the length of the edge between two adjacent chain teeth 30, and the upper thread and the lower thread interweave with each other on the edge through the first piercing hole and the second piercing hole.

[0052] Specifically, the first piercing hole 11 is located adjacent to the side edge of one of the chain teeth 30, and the second piercing hole 12 is located adjacent to the side edge of the other chain tooth 30 and is opposite to the first piercing hole 11. Both are located on the edge of the fabric body 10. The upper and lower threads of the sewing part 41 interweave with each other through the first and second piercing holes, thus fixing the upper and lower threads to the fabric body 10.

[0053] In the first embodiment of the zipper in this application, the upper and lower threads intertwine on the side of the support member 20 away from the fabric body 10.

[0054] In this way, the upper and lower threads wrap around and fix the support 20 to the fabric body 10, thereby fixing the chain teeth 30 to the fabric body 10.

[0055] Based on the first zipper embodiment described above, as a further preferred embodiment, the upper and / or lower threads include a first thread 411, a second thread 412, a third thread 413, a fourth thread 414, and a fifth thread 415. Specifically, the first thread 411 is formed by the upper or lower thread running from the first piercing hole along the side of one of the chain teeth 30 to the side; the second thread 412 is formed by the upper or lower thread running from the side in a direction inclined relative to the length direction of the support member 20 to the second piercing hole; the third thread 413 is formed by the upper or lower thread running from the second piercing hole along the edge to the first piercing hole; the fourth thread 414 is formed by the upper or lower thread running from the first piercing hole in a direction inclined relative to the length direction of the support member 20 to the side; and the fifth thread 415 is formed by the upper or lower thread running from the side along the side of another chain tooth 30 to the second piercing hole.

[0056] In addition, the fastener 40 also includes a connecting part 42, which is located between two adjacent sewing parts 41 and is sewn in a straight line on the fabric body 10 along the tail edge of the fitting chain tooth 30 for connecting the two adjacent sewing parts 41. That is, the fifth thread 415 of one sewing part 41 is connected to the first thread 411 of the other sewing part 41 through the connecting part 42.

[0057] It should be noted that the first thread 411, the second thread 412, the third thread 413, the fourth thread 414, the fifth thread 415 and the connecting part 42 mentioned above can be a continuous sewing thread.

[0058] In the second zipper embodiment of this application, the support member 20 is provided with a third piercing hole 21 and a fourth piercing hole 22 at intervals along its length at one end away from the edge. The third piercing hole 21 is provided corresponding to the first piercing hole 11, and the fourth piercing hole 22 is provided corresponding to the second piercing hole 12. The upper and lower threads are intertwined on the support member 20 through the third piercing hole 21 and the fourth piercing hole 22.

[0059] Specifically, the third piercing hole 21 is located adjacent to the side edge of one of the chain teeth 30, and the fourth piercing hole 22 is located adjacent to the side edge of the other chain tooth 30, and is opposite to the third piercing hole 21. Both are located on the edge of the support member 20 away from the fabric body 10. The upper and lower threads interweave through the third piercing hole 21 and the fourth piercing hole 22, thereby wrapping and fixing the support member 20 to the fabric body 10.

[0060] Based on the second zipper embodiment described above, as a further preferred embodiment, the upper and / or lower threads include a first thread 411, a second thread 412, and a third thread 413. Specifically, the first thread 411 is formed by the upper or lower thread running from the first piercing hole along a direction inclined relative to the length of the support member 20 to the fourth piercing hole; the second thread 412 is formed by the upper or lower thread running from the fourth piercing hole along the length of the support member 20 to the third piercing hole; and the third thread 413 is formed by the upper or lower thread running from the third piercing hole inclined relative to the length of the support member 20 to the second piercing hole.

[0061] It should be noted that two adjacent sewing sections 41 are connected by a connecting section 42. That is, the third thread 413 of one sewing section 41 is connected to the first thread 411 of another sewing section 41 through the connecting section 42. Similarly, the first thread 411, the second thread 412, the third thread 413 and the connecting section 42 mentioned above can be a continuous sewing thread.

[0062] In the third embodiment of the zipper in this application, this embodiment is a further preferred embodiment based on the second zipper embodiment described above. Specifically, the zipper tooth 30 includes a main body 31 and an engaging part 32. The main body 31 is disposed on the support member 20, and has grooves 311 on both sides facing the first thread 411 and the third thread 413, the grooves 311 being used to avoid the first thread 411 and the third thread 413; the engaging part 32 is disposed on the side of the main body 31 away from the fabric body 10.

[0063] like Figure 8 As shown, the two sides of the main body 31 of the chain tooth 30 are tapered, meaning that the width in the middle of the main body 31 is smaller than the width at both ends. This structure is designed to leave more sewing area for the use of sewing equipment.

[0064] Of course, it should be noted that the third type of zipper can be further optimized based on the first type of zipper.

[0065] In some embodiments of this application, the support member 20 is cylindrical.

[0066] Specifically, the support member 20 is a ribbed cylindrical strip with the same length as the main fabric body 10 and is arranged parallel to the main fabric body 10, through which multiple chain teeth 30 are sequentially threaded. Of course, this application does not limit the shape and size of the support member 20, and it can be set according to actual needs.

[0067] This application also provides a fabric including the zipper described above.

[0068] It should be noted that the above-mentioned fabrics can be bags, clothing, shoes and hats, but are not limited to clothing, bags, shoes and hats, and can also be other daily necessities with the above-mentioned zippers.

[0069] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0070] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
