Description

Technical Field

[0001] This application relates to the field of zipper technology, and more particularly to a concealed zipper structure. Background Technology

[0002] Invisible zippers consist of teeth, a slider, and locking mechanisms. The teeth are the key component, directly determining the zipper's lateral pulling strength. Generally, invisible zippers have two chain straps, each with a row of teeth, arranged in an alternating pattern. From the outside, the interlocking teeth on both sides of the zipper are not visible, thus enhancing the aesthetics and uniformity of the item.

[0003] like Figures 8-9 As shown, in the existing technology, each chain band is sewn to the chain fabric with stitching thread. The two chain fabrics can cover the chain teeth. However, if a force is continuously applied to the left side of the chain fabric, or a force is continuously applied to the right side of the chain fabric, or a force is continuously applied to the left side of the chain fabric and a force is continuously applied to the right side of the chain fabric at the same time, the relative gap between the two chain fabrics will increase, eventually causing the chain teeth to be exposed, which will affect the aesthetics and uniformity of the related items. Summary of the Invention

[0004] The purpose of this application is to propose an invisible zipper structure to solve the problem in the prior art where the zipper teeth are exposed after the zipper fabric is stressed, affecting the aesthetics and uniformity of related items.

[0005] An invisible zipper structure includes zipper teeth, zipper fabric, and fabric strip; one side of the zipper teeth is connected to the zipper fabric; the end of the zipper fabric near the zipper teeth can be sewn to the end of the fabric strip near the zipper teeth by a sewing thread.

[0006] Its beneficial effects are: the sewing thread can prevent the two strips of fabric from moving relative to each other after being stressed, preventing the chain teeth from being exposed and improving the appearance and uniformity of the items.

[0007] The strip of fabric can be folded, and the folded strip of fabric has at least one folding cavity; the two ends of the folding cavity are a first terminal and a second terminal, respectively.

[0008] Its beneficial effect is that the actual thickness of the fabric strip can be increased according to the increase in the number of folding cavities, which is equivalent to increasing the thickness of the fabric.

[0009] The second terminal can be sewn to the chain fabric with a sewing thread.

[0010] Its beneficial effect is that the sewing thread will not be exposed.

[0011] The first and second terminals can be sewn to the chain fabric with stitching.

[0012] Its beneficial effect is that the fixation between the fabric strip and the chain is more secure.

[0013] Several strips of fabric can be sewn together with the chain fabric using the same stitching thread.

[0014] Its beneficial effect is that it actually increases the thickness of the fabric on which the strip is located.

[0015] The second terminal of the topmost strip of fabric and several strips below it can be sewn together with the chain fabric using stitching.

[0016] Its beneficial effect is that the sewing thread will not be exposed.

[0017] The first and second terminals of the topmost strip of fabric, along with several strips of fabric below it, can be sewn together with the chain fabric using stitching.

[0018] Its beneficial effect is that the fixation between the fabric strip and the chain is more secure.

[0019] Among several strips of fabric, any two adjacent strips can be sewn together with a sewing thread. Attached Figure Description

[0035] like Figure 1 , 2 As shown, Example 1:

[0036] An invisible zipper structure includes a zipper tooth 1, a zipper fabric 2, and a fabric strip 3; the zipper fabric 2 is connected to one side of the zipper tooth 1; the end of the zipper fabric 2 near the zipper tooth 1 can be sewn to the end of the fabric strip 3 near the zipper tooth 1 by a sewing thread 4.

[0037] Its beneficial effects are: the sewing thread 4 can prevent the two strips of fabric 3 from moving relative to each other after being stressed, preventing the chain teeth 1 from being exposed, and improving the appearance and uniformity of the item.

[0038] like Figure 1 , 2 As shown, Example 2:

[0039] Based on Example 1, the difference between this embodiment and Example 1 is that the fabric strip 3 can be folded, and the folded fabric strip 3 has at least one folding cavity 33; the two ends of the folding cavity 33 are the first terminal 31 and the second terminal 32, respectively.

[0040] It should be noted that the lengths of the first terminal 31 and the second terminal 32 can be arbitrary. For example, the length of the first terminal 31 can be longer than the second terminal 32, or the length of the first terminal 31 can be shorter than the second terminal 32, or the length of the first terminal 31 can be equal to the length of the second terminal 32.

[0041] Its beneficial effect is that the actual thickness of the fabric strip 3 can be increased according to the increase in the number of folding cavities 33, which is equivalent to increasing the thickness of the fabric.

[0042] like Figure 1 , 2 As shown, Example 3:

[0043] This embodiment is based on embodiment 2, but differs from embodiment 2 in that the second terminal 32 can be sewn to the chain fabric 2 by the sewing thread 4.

[0044] Its beneficial effect is that the sewing thread 4 will not be exposed.

[0045] like Figure 3 , 4 As shown, Example 4:

[0046] This embodiment differs from Embodiment 2 in that the first terminal 31 and the second terminal 32 can be sewn to the chain fabric 2 via the sewing thread 4.

[0047] Its beneficial effect is that the fixation between the cloth strip 3 and the chain cloth 2 is more secure.

[0048] like Figure 5 As shown, Example 5:

[0049] This embodiment differs from Embodiment 2 in that several strips of fabric 3 can be sewn together with the chain fabric 2 through the same sewing thread 4.

[0050] Its beneficial effect is that it actually increases the thickness of the fabric where strip 3 is located.

[0051] like Figure 5 As shown, Example 6:

[0052] This embodiment differs from Embodiment 5 in that the second terminal 32 of the uppermost strip 3 and several strips 3 below it can be sewn together with the chain fabric 2 by the sewing thread 4.

[0053] Its beneficial effect is that the sewing thread 4 will not be exposed.

[0054] like Figure 6 As shown, Example 7:

[0055] This embodiment differs from Embodiment 5 in that the first terminal 31 and the second terminal 32 of the topmost fabric strip 3, along with several fabric strips 3 located below it, can be sewn together with the chain fabric 2 via the sewing thread 4.

[0056] Its beneficial effect is that the fixation between the cloth strip 3 and the chain cloth 2 is more secure.

[0057] like Figure 7 As shown, Example 8:

[0058] This embodiment differs from Embodiment 2 in that any two adjacent fabric strips 3 can be sewn together by a sewing thread 4.

[0059] The above descriptions are merely some embodiments of this application, used only to illustrate the technical solutions of this application, and not to limit it. It should be understood that those skilled in the art can make improvements or substitutions based on the above descriptions without departing from the inventive concept of this application, and all such improvements and substitutions should fall within the protection scope of the appended claims.
