Description

Technical Field

[0001] The utility model relates to the technical field of clothing accessories, and more specifically, to a waterproof zipper. In addition, the utility model also relates to a piece of clothing including the above waterproof zipper. Background Art

[0002] A zipper is an important part of clothing and luggage accessories. A zipper generally includes two cloth tapes, teeth provided on opposite sides of the two cloth tapes, and a slider used to engage and disengage the teeth on both sides. Usually, a waterproof film is provided on the cloth tape of a waterproof zipper or the cloth tape is impregnated with a waterproof agent to achieve a waterproof effect.

[0003] At present, in order to ensure the installation strength of the chain teeth on the zipper cloth tape provided with a liquid-tight layer, some liquid-tight zippers usually form a gap between the liquid-tight layer and the core in the width direction of the zipper cloth tape, so that a liquid-tight layer can be formed on the cloth tape member without deforming the core. However, since there is a gap between the liquid-tight layer and the core in the width direction of the zipper cloth tape, liquid may seep into the inside of the zipper from this gap, thus reducing the waterproofness of the zipper. And since there is a certain gap between the lower stop of the zipper and the lowermost teeth, liquid may enter the inside of the zipper from this gap, further reducing the waterproofness of the zipper.

[0004] In summary, how to improve the waterproof performance of the zipper is an urgent problem to be solved by those skilled in the art at present. Summary of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide a waterproof zipper, which effectively avoids liquid from entering the inside of the zipper through the gap and improves the waterproof performance of the zipper.

[0006] Another purpose of the utility model is to provide a piece of clothing including the above waterproof zipper.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A waterproof zipper includes a lower stop, two cloth tapes oppositely arranged on both sides of the lower stop, and a plurality of teeth correspondingly arranged at the edges of the two cloth tapes and meshing with each other. On the outer sides of the adjacent edges of the two cloth tapes, there are provided ribs for mounting the teeth. An installation groove adapted to the ribs is formed on the teeth. Waterproof films cover the outer sides of the two cloth tapes, and the edges of the waterproof films are attached to the edges of the ribs.

[0009] On the side of the lower stop facing the teeth, there is provided an adapting portion, and the shape of the adapting portion is adapted to the adjacent surfaces of the adjacent teeth to reduce the gap.

[0010] Preferably, a belt groove for the cloth belt to pass through is formed inside the tooth near one end of the cloth belt, and one side of the waterproof film close to the tooth passes through the belt groove and extends into the installation groove.

[0011] Preferably, the thickness of the waterproof film is 10%-15% of the thickness of the cloth belt.

[0012] Preferably, the size of the tooth located on the waterproof film is 20%-25% of the overall size of the tooth.

[0013] Preferably, the tooth includes an outer tooth part and an inner tooth part. The inner tooth part is used for the engagement between the teeth to open and close the zipper. The adapter part includes an outer adapter part that cooperates with the outer tooth part and an inner adapter part that cooperates with the inner tooth part;

[0014] A second adapter surface adapted to the inner tooth part is formed on the adjacent surface of the inner adapter part and the inner tooth part, and a first adapter surface adapted to the outer tooth part is formed on the adjacent surface of the outer adapter part and the outer tooth part.

[0015] Preferably, one end of the outer tooth part close to the corresponding tooth is a triangular structure with a rounded corner at the turning point, and a zigzag middle seam is formed between the meshing outer tooth parts.

[0016] Preferably, the turning angle range of the middle seam is 70°-80°.

[0017] Preferably, the clearance distance range between the outer adapter part and the adjacent tooth is 0.8mm-0.85mm.

[0018] Preferably, the ratio range of the thickness of the rib, the thickness of the cloth belt stacked with the waterproof film, and the thickness of the tooth is 5:12:29-10:25:59.

[0019] Preferably, the gap distance between the teeth on the same cloth belt is 13%-15% of the width of the tooth.

[0020] A piece of clothing includes the waterproof zipper described in any one of the above.

[0021] The beneficial effect of the waterproof zipper provided by the present utility model is that: by providing an adapter part on the lower stop that is adapted to the lower surface of the lowermost tooth, the gap between the lower stop and the tooth is reduced, thereby effectively preventing liquid from entering the inside of the zipper through this gap, and improving the waterproof performance of the zipper. At the same time, by providing ribs on the cloth belt for installing the teeth to improve the connection strength of the teeth, and using a waterproof film to completely cover the entire outer side of the cloth belt, and its edge abuts against the edge of the rib, thereby reducing the gap between the teeth and the cloth belt, effectively preventing liquid from entering the inside of the zipper through the gap, and further improving the waterproof performance of the zipper.

[0022] Among the further solutions provided by this application, at least one of the following beneficial technical effects can also be achieved:

[0023] By passing the waterproof film through the groove and extending it into the installation groove, and further filling the gap between the teeth and the cloth tape with the waterproof film, the waterproof performance of the zipper is further improved;

[0024] With the cooperation of the first mating surface and the outer tooth part and the cooperation of the second mating surface and the inner tooth part, the fitting part is closer to the lowermost tooth, and then the gap between the bottom stop and the lowermost tooth is relatively smaller, thus further improving the waterproof performance of the zipper;

[0025] By adopting a triangular structure with a rounded corner at the turning point at one end of the outer tooth part close to the corresponding tooth, the overall shape of the middle seam formed between multiple outer tooth parts is a slender gap composed of multiple broken lines. The broken-line-shaped middle seam is less likely to accumulate water, and the water flow is more likely to flow along the broken-line-shaped middle seam to the lower side of the zipper and drain out, effectively avoiding the accumulation of liquid at the tooth gaps.

The embodiments of this application disclose a waterproof zipper.

[0038] The core of the present invention is to provide a waterproof zipper. Another core of the present invention is to provide a garment including the above waterproof zipper.

[0039] Please refer to Figures 1 to 5 , in which Figure 1 is the first perspective structural diagram of the waterproof zipper, Figure 2 is the second perspective structural diagram of the waterproof zipper, Figure 3 is the structural diagram of the teeth, Figure 4 is the structural diagram of the lower stop, Figure 5 is the top view of the connection between the teeth and the cloth tape.

[0040] The waterproof zipper provided by the present utility model includes a lower stop 1, two cloth tapes 2 oppositely arranged on both sides of the lower stop 1, and a plurality of teeth 3 correspondingly arranged at the edges of the two cloth tapes 2 and meshing with each other. Reinforced ribs 4 for installing the teeth 3 are provided on the outer sides of the adjacent edges of the two cloth tapes 2. Installation grooves 5 adapted to the reinforced ribs 4 are formed on the teeth 3. Waterproof membranes 6 cover the outer sides of both cloth tapes 2, and the edges of the waterproof membranes 6 are attached to the edges of the reinforced ribs 4. An adaptation part 7 is provided on one side of the lower stop 1 facing the teeth 3, and the shape of the adaptation part 7 is adapted to the adjacent surface of the tooth 3 adjacent to it to reduce the gap.

[0041] In this embodiment, by providing an adaptation part 7 on the lower stop 1 that is adapted to the lower surface of the lowermost tooth 3, the gap between the lower stop 1 and the teeth 3 is reduced, thereby effectively preventing liquid from entering the inner side of the zipper through this gap and improving the waterproof performance of the zipper. At the same time, by providing reinforced ribs 4 for installing the teeth 3 on the cloth tapes 2, the connection strength of the teeth 3 is improved, and the entire outer side of the cloth tapes 2 is covered with the waterproof membranes 6, and the edges thereof are abutted against the edges of the reinforced ribs 4, thereby reducing the gap between the teeth 3 and the cloth tapes 2 and effectively preventing liquid from entering the inner side of the zipper through the gap, and further improving the waterproof performance of the zipper.

[0042] The following will introduce the waterproof zipper provided by the present utility model in more detail with reference to the accompanying drawings and specific embodiments.

[0043] In a specific embodiment, referring to Figure 5 , an installation groove 5 for engaging with the reinforced rib 4 is formed at one end of the tooth 3 close to the cloth tape 2. The end of the reinforced rib 4 close to the tooth 3 is arranged in the installation groove 5. A belt groove 8 is formed on the tooth 3 on the side of the installation groove 5 close to the cloth tape 2. The belt groove 8 can effectively facilitate the passing of the cloth tape 2, and the waterproof membrane 6 covering the cloth tape 2 passes through the belt groove 8 and extends into the installation groove 5 to achieve the filling of the gap between the tooth 3 and the cloth tape 2 by the waterproof membrane 6.

[0044] The formation of the belt groove 8 can better facilitate the passing of the cloth tape 2 and the waterproof membrane 6 on the cloth tape 2, facilitate the filling of the waterproof membrane 6 between the cloth tape 2 and the tooth 3, effectively reduce the gap between the tooth 3 and the cloth tape 2, and thus improve the waterproof performance of the zipper. At the same time, by extending the waterproof membrane 6 through the belt groove 8 into the installation groove 5, the contact area between the waterproof membrane 6 and the tooth 3 is effectively increased, thereby avoiding the problem of liquid infiltration caused by too short contact area and further improving the waterproof performance of the zipper.

[0045] Based on any of the above embodiments, the ratio of the thickness of the waterproof film to the thickness of the cloth tape can be in the range of 10%-15%. Through many actual experiments, it is found that within this range, the waterproof film 6 can produce sufficient waterproof effect and improve the waterproof performance of the zipper, while also preventing the problem of the softness of the cloth tape and the smoothness of the pull head being affected by the excessive thickness of the waterproof film 6.

[0046] Furthermore, the ratio of the thickness of the rib 4, the thickness of the cloth tape 2 superimposed on the waterproof membrane 6 and the thickness of the tooth 3 can be in the range of 5:12:29-10:25:59. Through many actual experiments, it is found that within this range, the connection strength of the tooth 3 on the cloth tape 2, the waterproof effect of the waterproof membrane 6, the softness of the cloth tape 2 and the smoothness of the zipper pull can be taken into account.

[0047] Based on any of the above embodiments, the size of the teeth 3 located on the waterproof membrane 6 can be in the ratio range of 20%-25% compared to the overall size of the teeth 3. It is found through multiple actual experiments that within this range, while the binding force of the teeth 3 on the tape 2 can be ensured, the teeth 3 can also extend a sufficient distance from the edge of the tape 2 for the teeth 3 to bite each other, thereby ensuring the closing strength of the zipper.

[0048] In a specific embodiment provided in this application, reference Figure 3 and Figure 4 The teeth 3 include an outer tooth portion 31 and an inner tooth portion 32. The inner tooth portion 32 is used for the engagement between the teeth 3 to open and close the zipper. The adapting portion 7 includes an outer adapting portion 71 that cooperates with the outer tooth portion 31 and an inner adapting portion 72 that cooperates with the inner tooth portion 32. The adjacent surfaces of the inner adapting portion 72 and the inner tooth portion 32 are formed with a second adapting surface 74 that cooperates with the inner tooth portion 32. The adjacent surfaces of the outer adapting portion 71 and the outer tooth portion 31 are formed with a first adapting surface 73 that cooperates with the outer tooth portion 31.

[0049] With the help of the first matching surface 73 cooperating with the outer tooth portion 31 and the second matching surface 74 cooperating with the inner tooth portion 32, the matching portion 7 and the lowermost tooth 3 are brought closer together, thereby making the gap between the lower stop 1 and the lowermost tooth 3 relatively smaller, thereby preventing liquid from entering the inner side of the zipper through the gap, thereby further improving the waterproof performance of the zipper.

[0050] For further reference, Figure 3 The inner tooth portion 32 of the tooth 3 can be composed of a tooth head 321, a tooth socket 322 and a tooth foot 323. Therefore, the second matching surface 74 is formed by multiple curved surfaces with the same lower surface shape curve as the tooth head 321, the tooth socket 322 and the tooth foot 323 of the tooth 3, so that the second matching surface 74 can better adapt to the inner tooth portion 32 of the tooth 3, so that the gap between the inner tooth portion 32 and the lower stop 1 is smaller, further improving the waterproof performance of the zipper.

[0051] Based on any one of the above embodiments, with reference to Figure 5 , one end of the outer tooth part 31 close to the corresponding tooth 3 is a triangular structure with a rounded corner at the turning point. A zigzag middle seam 9 is formed between the meshing outer tooth parts 31. While the zigzag middle seam 9 provides the aesthetic appearance on the outer side of the zipper, for some teeth 3, only the tooth head 321 and the tooth socket 322 are in partial meshing contact. The triangular design can make the two sides of the teeth 3 closer to each other, reduce the gap amount, and thus improve the waterproof performance of the zipper. And compared with the winding middle seam 9 formed by the lower tooth part with the tooth head 321 and the tooth socket 322 structure, the zigzag middle seam 9 is less likely to accumulate water, and the water flow is more likely to flow along the zigzag middle seam 9 to the lower side of the zipper and drain out.

[0052] Furthermore, the turning angle range of the middle seam is 70° - 80°. Through multiple actual experiments, it is found that within this range, while making the zipper more aesthetically pleasing, it can also prevent the upper tooth part from being interfered by other upper tooth parts when the teeth 3 are meshed and effectively remain in the properly designed position (the above-mentioned upper tooth part and lower tooth part refer to the upper and lower parts of the teeth from a top-down perspective).

[0053] Based on any one of the above embodiments, the gap distance between the outer fitting part and the adjacent tooth ranges from 0.8 mm to 0.85 mm. Through multiple actual experiments, it is found that within this range, the zipper can maintain a good waterproof effect while not affecting the meshing and separation between the teeth 3 and the lower stop 1, ensuring the stable performance of the zipper during use.

[0054] Based on any one of the above embodiments, the ratio range of the gap distance between the teeth 3 on the same tape 2 to the width of the teeth 3 is 13% - 15%. If the gap between the teeth 3 is too small, it is difficult for the zipper to mesh and separate. If it is too large, it will affect the sealing performance of the zipper and is prone to chain breakage. Through multiple actual experiments, it is found that within the above range, the gap between the teeth 3 is small enough to ensure the waterproof sealing of the zipper, and it will not affect the meshing and separation between the teeth 3, ensuring the normal operation and cooperation of all components.

[0055] Based on any of the above embodiments, after the teeth 3 on the tape 2 arranged oppositely on the left and right are engaged, there will be a certain gap between the upper tooth parts of the triangular outer tooth parts 31 of the relatively engaged teeth 3 (i.e., the middle seam 9 mentioned above). The ratio range of the size of the middle seam 9 to the spacing size between the teeth 3 can be 66%-88%. Through multiple actual experiments, it is obtained that within the above range, while ensuring the sealing and aesthetics of the zipper, it can also ensure that the upper tooth parts of the teeth 3 are not interfered by other teeth 3 when the teeth 3 are engaged, so as to effectively be in the normally designed position, ensuring the stability during the zipper operation.

[0056] By providing an adaptation part 7 on the lower stop 1 that is adapted to the lower surface of the lowermost tooth 3, the gap between the lower stop 1 and the tooth 3 is reduced, thereby effectively preventing liquid from entering the inner side of the zipper through this gap, improving the waterproof performance of the zipper. At the same time, by providing a rib 4 for installing the teeth 3 on the tape 2 to improve the connection strength of the teeth 3, and using a waterproof film 6 to completely cover the entire outer side of the tape 2, and its edge abuts against the edge of the rib 4, thereby reducing the gap between the teeth 3 and the tape 2, effectively preventing liquid from entering the inner side of the zipper through the gap, and further improving the waterproof performance of the zipper.

[0057] Based on any of the above embodiments, referring to Figure 6 , in this embodiment, when the zipper is an open-end zipper, the adaptation part 7 of the lower stop is formed on the upper surface of the plug 10, and a fixing part 11 that cooperates with the plug 10 is formed at the other end of the lower stop 1. The upper surface of the fixing part 11 cooperates with the lower surface of the adaptation part 7 to reduce the gap between the fixing part 11 and the adaptation part 10, thereby ensuring the waterproof performance of the open-end zipper.

[0058] Based on any of the above embodiments, referring to Figure 7 , in this embodiment, when the zipper is a double-open zipper, the lower stop 1 includes a left plug 12 and a right plug 13 that are relatively arranged on the two tapes 2. Among them, the adaptation part 7 is formed on the upper surface of the left plug 12, and the upper surface of the right plug 13 cooperates with the lower surface of the adaptation part 7, thereby reducing the gap between the right plug 13 and the adaptation part 10, and ensuring the waterproof performance of the double-open zipper.

[0059] In addition to the waterproof zippers disclosed in the above various embodiments, the present utility model also provides a piece of clothing, including any one of the waterproof zippers in the above embodiments. Since this piece of clothing uses the waterproof zipper in the above embodiments, the beneficial effects of this piece of clothing can be referred to the above embodiments.
