AI Technical Summary
Zippers are prone to buckling during use due to uneven tension and mismatched zipper tape lengths. Existing technology makes it difficult to maintain both the flexibility and tight closure of the zipper tape simultaneously.
Design an anti-arching zipper by introducing elastic fabric and an elastic band structure into the zipper tape. The elastic band keeps the opening length consistent, and the pleated fabric of the elastic material provides elastic restraint to prevent excessive stretching.
It effectively reduces the risk of zipper arching, maintains the consistency and flexibility of zipper tape length, and ensures that the zipper remains tight when closed.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of zipper technology, specifically to an anti-arching zipper. Background Technology
[0002] A zipper is a common fastener used to connect two edges, commonly used in clothing, bags, tents and a variety of other items. It consists of two strips with teeth that can hook together and be opened or closed by a sliding mechanism to form a continuous closed system.
[0003] Zipper arching is a common problem during zipper use, affecting the overall appearance. There are two main reasons for arching: uneven tension and a mismatch between the zipper opening length and the zipper tape length, causing arching in the middle. A common solution is to add an elastic structure to the zipper tape to increase its flexibility and better adapt to the shape and movement of clothing or items, thus reducing the likelihood of arching. However, if the elastic structure is too strong, the zipper may not close tightly, increasing the likelihood of arching. Therefore, it is necessary to design a zipper tape that can limit elasticity and maintain consistency between the zipper opening and the zipper tape length. Utility Model Content
[0004] The purpose of this invention is to provide an anti-arching zipper to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a hook-and-loop tape, a zipper tape, and a zipper head. The hook-and-loop tape has an opening, and the zipper tape is sewn to the opening with stitching. A row of teeth is fixed to one side of the zipper tape, and the zipper head is installed between the teeth. The zipper tape is composed of end fabric, elastic fabric, and connecting fabric. The teeth are fixed to the end fabric, and an elastic band is provided inside the elastic fabric. The connecting fabric is sewn to the hook-and-loop tape with stitching and has an elastic band inside.
[0006] Preferably, the elastic fabric has two layers of pleated fabric pieces, which are respectively disposed on the upper and lower sides of the elastic band, and the pleated fabric pieces are made of non-elastic fabric.
[0007] Preferably, the two ends of the connecting fabric are sewn to both sides of the elastic fabric, and perforations are provided inside. The elastic band passes through the perforations, and the sewing thread passes through the connecting fabric and the elastic band.
[0008] Preferably, the outer edge grooves are equidistantly provided on the outer side of the connecting fabric, and the stitching width of the stitching line exceeds the width of the outer edge grooves.
[0009] Preferably, an upper limiting block is fixed on the zipper tape above the toothed block, and a lower limiting block is fixed on the zipper tape below the toothed block.
[0010] Preferably, the toothed blocks on both sides are staggered on the zipper tape and mesh with each other.
[0011] Compared with the prior art, the beneficial effects of this utility model are: the elastic bands on both sides can be used to shrink synchronously when the opening of the hook and loop tape shrinks, ensuring that the opening length is consistent with the length of the zipper tape connection, reducing the risk of arching; and on the basis of setting the elastic band, pleated fabric pieces are added simultaneously for elastic restraint, reducing the arching phenomenon caused by excessive elasticity.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-3This utility model provides a technical solution including a hook-and-loop tape 1, a zipper tape 2, and a zipper head 4. The hook-and-loop tape 1 has an opening 11. The zipper tape 2 is sewn to the opening 11 by a sewing thread 5. A row of teeth 3 is fixed on one side of the zipper tape 2. The zipper head 4 is installed between the teeth 3. The zipper tape 2 is composed of end fabric 21, elastic fabric 22, and connecting fabric 23. The teeth 3 are fixed on the end fabric 21. An elastic band 221 is provided inside the elastic fabric 22. The connecting fabric 23 is sewn to the hook-and-loop tape 1 by a sewing thread 5 and has an elastic band 24 inside. An upper limit block 6 is fixed on the zipper tape 2 above the teeth 3. A lower limit block 7 is fixed on the zipper tape 2 below the teeth 3. The teeth 3 on both sides are staggered on the zipper tape 2 and mesh with each other.
[0018] The elastic fabric 22 has two layers of pleated fabric pieces 222, which are respectively set on the upper and lower sides of the elastic band 221. The pleated fabric pieces 222 are made of non-elastic fabric 22. The two ends of the connecting fabric 23 are sewn to the two sides of the elastic fabric 22, and perforations are provided inside. The elastic band 24 passes through the perforations, and the sewing thread 5 passes through the connecting fabric 23 and the elastic band 24. The outer side of the connecting fabric 23 is provided with outer edge grooves 25 at equal intervals, and the sewing width of the sewing thread 5 exceeds the width of the outer edge groove 25.
[0019] Working principle: First, select a zipper tape 2 of appropriate length and sew it to the opening 11 of the zipper tape 1. Using the pull of the zipper head 4, the teeth 3 engage and open, thus closing the opening 11. During this process, the teeth 3 need to be installed equidistantly onto the end fabric 21 of the zipper tape 2. Then, the elastic fabric 22, composed of the elastic band 221 and the pleated fabric piece 222, is sewn to the end of the end fabric 21. Next, the two ends of the connecting fabric 23 are sewn to the side of the elastic fabric 22 away from the teeth 3. The elastic band 24 is inserted into the perforation between the connecting fabrics 23 and secured in the perforation by the stitching thread 5. During use, if the zipper tape 1 shrinks during washing, causing the opening to... Since the opening 11 is relatively short, the elastic band 24 can be used to shrink the zipper tape 2 so that the length of the sewn position is consistent with the length of the opening 11. The outer groove 25 can prevent the zipper tape 2 from wrinkling and bulging after shrinkage. The elasticity of the elastic fabric 22 can increase the flexibility of the zipper tape 2, making it better adapt to the shape and movement of clothing or items, thereby reducing the possibility of arching. During this process, the stretching of the elastic band 221 will cause the wrinkled fabric piece 222 to straighten. After it is completely straightened, it cannot continue to extend, thus avoiding the excessive extension of the elastic band 221. The elastic strength is limited to a certain extent to prevent the elastic structure from being too strong, which may make it difficult for the zipper to stay tight when closed.
