Zippers and zipper applications

technical field

The present invention relates to the field of zipper. The cloth belt of the zipper has a double-layer structure and two free ends separated from each other, and the double-layer structure is formed by bending the cloth belt itself, rather than combining two cloth belts. The zipper of the present invention is formed by laminating and connecting the zipper tapes, and the zipper of the present invention can be selected by the next process to place the two free ends of the cloth-like tape simultaneously on the same side of the stitching part of the zipper application or the zipper application. Stored between the two free ends of the cloth belt or other stitching methods. The present invention also relates to a zipper application to which the zipper is applied.

Background technique

At present, the zippers on the market generally use a single-layer tape, and the elements of the zipper are arranged at the end of the single-layer tape. When the zipper is sewn to the zipper application, the single-layer tape can only be placed in the zipper application. The inner or outer side of the product has a single sewing method. In addition, if the zipper is applied to the seam part with the outer layer and the inner layer as shown in FIG. 1, in order to improve the aesthetics, the outer layer 1a and the inner layer 2a need to be flanged at the seam part of the zipper application product at the same time. , at this time, the two-layer flanging layer of the outer layer 1a, the single-layer cloth tape 3a and the two-layer flanging layer of the inner and inner layer 2a form a total of five-layer structure, resulting in an excessively thick overall thickness, and the outer layer 1a, the inner layer The sewing process of 2a and tape 3a is complicated.

In order to solve the problems caused by the above-mentioned single-layer belt, the prior art proposes a double-layer structure belt, such as the utility model patent with the Chinese publication number CN209528074U, which discloses a double-layer chain belt and the use of the double-layer chain belt. The zipper of the chain belt, the double-layer chain belt includes a pair of cloth belts; a pair of chain tooth rows, which are respectively installed on the pair of cloth belts, and can be engaged and separated from each other; the cloth belts include a layered arrangement The inner cloth tape layer and the outer cloth tape layer, the inner cloth tape layer faces inward, and the outer cloth tape layer faces outward; the chain teeth; the outer end of the inner tape layer is separated from the outer end of the outer tape layer. Wherein, the connection mode of the engagement end of the inner tape layer and the engagement end of the outer tape layer is stitching or bonding.

Secondly, the utility model patent with the publication number of CN203341119U in China discloses a three-proof high-strength double-layer tooth zipper, which includes a left and right double-layer toothed chain that meshes with each other and is made of upper and lower two-layer zipper chains and cloth tapes sewn together. The belt and the zipper puller for opening and closing the left and right double-layer toothed chain belts are characterized in that the cloth belts are folded into two layers, and zipper chains are sewn on the edges of the outer surfaces of the upper and lower cloth belts. The folded tapes are sewn to each other with harnesses. The utility model makes the zipper chain and the cloth tape be in the stitched state of a single layer of the zipper chain and the cloth tape, greatly improves the sewing speed, the sewing needle will not be broken, and a layer of the zipper chain and a layer of the cloth tape are sewn together. The double-layer zipper chain has double-strand wire harnesses sewn with the cloth tape respectively, and its connection strength is doubled compared with the traditional one. However, this patent proposes a structure of folded tape based on solving the problem of inconvenient sewing of double-layer teeth, and it is precisely because of the technical problem solved by this published patent that it chooses to sew or glue the folded tape. , and the folded tape is still equivalent to the single-layer tape structure of the prior art.

SUMMARY OF THE INVENTION

Analyzing the technical solution of the above-mentioned bulletin number CN209528074U, it is found that a cloth tape with a double-layer structure is formed by connecting the inner cloth tape layer and the outer cloth tape layer by stitching or bonding. It can be seen that the cloth tape itself has an inner layer. The connection process of the tape layer and the outer tape layer not only increases the complexity of processing, but also the inner tape layer and the outer tape layer are prone to dislocation during the lamination connection process, which affects the yield of product production. The utility model patent with the Chinese publication number CN203341119U has a double-layered tape, but the folded tape is finally sewn or bonded, and the folded tape is still equivalent to the single-layer tape structure of the prior art. , the structure process is very complex.

In view of this, the present invention discloses a slide fastener, comprising a fastener tape; the fastener tape comprises a single-layer cloth-like tape, and the single-layered cloth-like tape is bent to form a double-layer structure and is bent to form two tapes away from the bent ends. There are two free ends, the two free ends are relatively separated, and the two relatively separated free ends are used to facilitate at least two free ends to be simultaneously placed on the seam part of the zipper application in the next process. One side or the stitching part of the zipper application is accommodated between the two free ends; the fastener tape is arranged with a fastener element at the bent part of the cloth belt or a region close to the bent part, A slider is also included, and the slider is used to engage or separate the fastener elements on a pair of the chain belts.

Wherein, the cloth belt can be made of textile cloth, non-woven fabric, fiber mesh, or plastic cloth belt, as long as it can be ensured that the cloth belt can be bent into a double-layer structure.

Wherein, the said zipper-applied products refer to items that use a zipper as the closing or opening part of the opening, such as clothes, shoes and hats, luggage and other products. The seam part of the said zipper-applied product refers to the part on the said zipper-applied product which is used to combine the said zipper.

Wherein, the single-layered cloth-like tape is bent to form a double-layer structure and is bent to form two free ends that are far away from the bending end and are relatively separated, which defines that the cloth-like tape itself is a single-layer structure, and the double-layer structure It is formed by bending the cloth-like belt itself, and the bent cloth-like belt forms two free ends away from the bending end, and the two free ends are not limited to the ends of the cloth-like belt. A portion, for example, it may also be the cloth-like tape having a portion of a certain width.

Wherein, the fastener element is arranged at the bending part of the cloth belt or a region close to the bending part, which defines that the fastener element can be arranged at the bending part of the cloth belt. When the fastener elements are arranged on the end face in the width direction of the cloth-shaped belt after bending, it is also defined that the fastener elements can also be arranged in the area close to the bending part. At this time, the fastener element row The cloth is arranged on the upper side or the lower side of the cloth-shaped belt after bending, and the fastener element is close to the bending end of the cloth-shaped belt.

Wherein, the two free ends are relatively separated, and the two relatively separated free ends are used to facilitate at least being able to select the two free ends to be simultaneously placed on the seaming part of the zipper application in the next process. One side or accommodating the seam part of the zipper application between the two free ends defines that in the next process of zipper manufacture, at least two of the free ends can be selected to be simultaneously arranged to the seam of the zipper application One side of the seam part, or choose to store the seam part of the zipper application between the two free ends, or choose other seam joint methods, for example, when the seam part has two layers of outer layer and inner layer When the two free ends are placed on the same side of the outer or inner layer, the other inner layer or outer layer is accommodated between the two free ends.

Compared with the prior art, the present invention has the following main beneficial effects:

1. The present invention forms a double-layer structure by bending the single-layered cloth-like belt.

In this way, the bent portion of the cloth belt is thinner than the non-bent portion, which not only plays a prominent role, but also improves the convenience of bending the cloth belt.

Wherein, the cloth belt can use the following ways to achieve the above purpose:

In the first way, the cloth belt is a woven cloth, the woven texture of the folded part is thinner than the woven texture of the non-folded part, or the yarn density of the folded part is thinner than that of the non-folded part of the yarn low density. Both of these two methods achieve the purpose of thinning the bending portion directly in the process of weaving the cloth-like belt. For example, the weaving texture of the bending part adopts plain weave, and the non-bending part adopts twill weave or other weaving texture thicker than plain weave.

In the second method, the film product is attached to the non-bending part but not the bending part, so that the thickness of the non-bending part is greater than the thickness of the bending part. In this way, the thickness of the non-bending part is increased so that the thickness of the bending part is lower than that of the non-bending part.

A further technical solution can also be that the fastener elements can be set in the following three ways:

In a first manner, the fastener elements are nylon fastener elements, and the nylon fastener elements are sewed on the cloth-like belt with a suture thread. In this way, the nylon elements can be sewn on the cloth belt when the cloth belt has a single-layer structure, and after the nylon elements are sewn together, the cloth belt can be directly The nylon fastener elements are used as the bending lines, so that the nylon fastener elements are arranged at the bending part of the cloth-shaped belt of the double-layer structure, and the cloth-shaped belt can also be located in a lateral position close to the fastener elements.
