Description

[0001] The present application claims priority to Chinese Patent Application No. 202410831003.3, titled "ANTI-BREAKAGE SUB-CHAIN, ANTI-BREAKAGE SLIDE CHAIN AND GARMENT", filed with the China National Intellectual Property Administration on June 25, 2024, which is incorporated herein by reference in its entirety.FIELD

[0002] The present application relates to the technical field of garment accessories, and in particular to an anti-breakage male chain, an anti-breakage slide zipper, and a garment.BACKGROUND

[0003] An existing slide zipper typically includes a male chain and a female chain. The female chain is provided with inner cavities for teeth, while the male chain is correspondingly provided with a teeth part that matches the tooth inner cavities. The teeth part of the male chain slides in the inner cavities of the female chain for teeth, so as to achieve relative movement between the female chain and the male chain. The slide zipper is now widely used in clothing, packaging, pockets, tents, or the like. Generally, the teeth of the male chain slide in the inner cavities of the female chain for teeth. In the conventional technology, during transportation of the male chain of the slide zipper, it may bend in a thickness direction of a cloth tape, which inevitably causes the teeth of the male chain to collide with each other, leading to chain bursting. That is, the teeth may be damaged or even broken.

[0004] Therefore, how to prevent the male chain of the slide zipper from breakage when it bends in the thickness direction of the cloth tape is a technical issue that needs to be addressed by those skilled in the field at present.SUMMARY

[0005] An object of the present application is to provide an anti-breakage male chain that can prevent the male chain from breakage when the slide zipper bends in the thickness direction of the cloth tape. An anti-breakage slide zipper including the aforementioned anti-breakage male chain and a garment including the aforementioned anti-breakage slide zipper are further provided according to the present application.

[0006] In order to achieve the above object, the following technical solutions are provided according to the present application.

[0007] An anti-breakage male chain includes multiple male teeth spaced apart from each other. The male teeth include first teeth and second teeth that are alternately arranged. Each first tooth and each second tooth includes a male tooth base and a connecting portion provided on the male tooth base. The male tooth base is divided into a first part and a second part by the connecting portion. The first tooth further includes a first protrusion located above the first part of the male tooth base and connected to an end portion of the connecting portion of the first tooth. The second tooth further includes a second protrusion located above the second part of the male tooth base and connected to an end portion of the connecting portion of the second tooth.

[0008] As a preferred embodiment, grooves for mounting of a cloth tape are provided on both sides of the male tooth base in a first direction.

[0009] As a preferred embodiment, chamfers or fillets are provided on both side surfaces of the male tooth base in a second direction.

[0010] As a preferred embodiment, the connecting portion is arranged on a symmetry axis of the male tooth base that extends in the second direction, and a length of each of the first protrusion and the second protrusion in the second direction matches a length of the respective connecting portion in the second direction.

[0011] The connecting portion is perpendicular to an upper surface of the male tooth base and is perpendicular to both the first protrusion and the second protrusion.

[0012] As a preferred embodiment, curved guide surfaces are provided on both sides of each of the first protrusion and the second protrusion in the second direction.

[0013] As a preferred embodiment, extension portions are provided at both ends of each of the first protrusion and the second protrusion in the second direction. The extension portions of each two adjacent male teeth abut against each other, with abutment surfaces being smooth curved surfaces.

[0014] As a preferred embodiment, each male tooth is integrally formed by injection molding.

[0015] As a preferred embodiment, a ratio of a spacing between each two adjacent male teeth to a length of each male tooth in the second direction is specifically between 1 / 5 and 1 / 3.

[0016] An anti-breakage slide zipper includes a female chain and the anti-breakage male chain as described in any of the above solutions.

[0017] A garment includes the anti-breakage slide zipper as described above.

[0018] Compared with the background technology mentioned above, the anti-breakage male chain according to the present application includes multiple male teeth spaced apart from each other. The male teeth include alternately arranged first teeth and second teeth. Each of the first teeth and the second teeth includes a male tooth base and a connecting portion provided on the male tooth base. The connecting portion divides the male tooth base into a first part and a second part. Each first tooth further includes a first protrusion located above the first part of the male tooth base and connected to an end portion of the connecting portion of the first tooth. Each second tooth further includes a second protrusion located above the second part of the male tooth base and connected to an end portion of the connecting portion of the second tooth.

[0019] Specifically, when the male chain formed by the multiple male teeth bends inward, i.e., when the male chain bends such that the first teeth and the second teeth of the male teeth are located on an inner side of the bend and the male tooth bases are located on an outer side of the bend, the inner radius of the bend will gradually decrease, and the first teeth and the second teeth are pressed inward. Due to the alternating arrangement of the first teeth and the second teeth, when the male chain bends, the first protrusions of the first teeth will be pushed to a back side of the second protrusions of the second teeth, and similarly, the second protrusions of the second teeth will be pushed to a back side of the first protrusions of the first teeth. This prevents the male teeth from bursting (i.e., being damaged) due to the teeth pressing against each other when the male chain bends inward.BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solutions according to the embodiments of the present application will be described clearly and completely as follows with reference to the drawings in the embodiments of the present application. It is apparent that the described embodiments are only some of the embodiments according to the present application, rather than all the embodiments. Any other embodiments obtained by those skilled in the art based on the embodiments of the present application without any creative effort shall fall within the protection scope of the present application.

[0023] In order to enable those skilled in the art to better understand the solutions of the present application, the present application is described in further detail hereinafter with reference to the drawings and specific embodiments.

[0024] In description of the present application, it should be noted that the orientations or positional relationships indicated by terms such as "above", "below", "end portion", and the like are based on the orientations or positional relationships shown in the drawings, and are merely for the convenience of describing the present application and simplifying the description, rather than indicating or implying that a position or element referred to must have a particular orientation, or be configured and operated in a particular orientation, which therefore should not be construed as a limitation to the present application.

[0025] An object of the present application is to provide an anti-breakage male chain that can prevent the male chain from bursting when the slide zipper bends in the thickness direction of the cloth tape.

[0026] It should be noted that in this embodiment, a direction indicated by X in the accompanying drawings is defined as a first direction, and a direction indicated by Y is defined as a second direction. The first direction and the second direction are perpendicular to each other.

[0027] In order to achieve the above object, the following technical solutions are provided according to the present application.

[0028] Referring to FIGS. 1 and 2, an anti-breakage male chain is provided according to this embodiment of the present application. The anti-breakage male chain includes multiple male teeth 100 spaced apart from each other. The male teeth 100 include first teeth 110 and second teeth 120 that are alternately arranged. Each of the first teeth 110 and the second teeth 120 includes a male tooth base 130 and a connecting portion 140 provided on the male tooth base 130. The connecting portion 140 divides the male tooth base 130 into a first tooth part 131 and a second part 132. Each first tooth 110 further includes a first protrusion 150 located above the first part 131 of the male tooth base and connected to an end portion of the connecting portion 140 of the first tooth. Each second tooth 120 further includes a second protrusion 160 located above the second part 132 of the male tooth base and connected to an end portion of the connecting portion 140 of the second tooth.

[0029] Specifically, as shown in FIGS. 1 and 2, the male teeth 100 of the male chain include two types, namely the first teeth 110 and the second teeth 120. The male chain is formed by the alternately arranged first teeth 110 and second teeth 120. The first teeth 110 and the second teeth 120 have the same overall shape, but differ in that the first protrusions 150 of the first teeth 110 are arranged opposite to the second protrusions 160 of the second teeth 120 with respect to the connecting portions 140 as a central axis, that is, the first protrusions 150 are arranged opposite to the second protrusions 160 in the first direction. As shown in FIG. 1, the first protrusions 150 of the first teeth 110 protrude opposite to the first direction. It should be noted that a side of the connecting portion 140 of each first tooth in the first direction is flush with the first protrusion 150, that is, the protrusion is provided on only one side of the end portion of the connecting portion 140. Similarly, each second tooth 120 has the same overall shape as that of each first tooth 110, but they differ in that the second protrusion 160 is provided on a side of the connecting portion 140 of the second tooth facing in the first direction. In this way, the first protrusions 150 and the second protrusions 160 are alternately arranged on respective sides of the connecting portions 140 with the connecting portions 140 being as the central axis. Specifically, the first protrusion 150 is located only above the first part 131 of the male tooth base, and the second protrusion 160 is located only above the second part 132 of the male tooth base.

[0030] A case where the male chain formed by the multiple male teeth 100 bends inward is described. That is, the male chain bends such that the first teeth 110 and the second teeth 120 of the male teeth 100 are located on an inner side of the bend and the male tooth bases 130 are located on an outer side of the bend. This bending manner is specifically shown in the upper part in FIG. 2. In this case, an inner radius of the bend will gradually decrease, and the first teeth 110 and the second teeth 120 are pressed inward. Due to the alternating arrangement of the first teeth 110 and the second teeth 120, when the male chain bends, the first protrusions 150 of the first teeth 110 are pushed to the back side of the second protrusions 160 of the second teeth 120, and similarly, the second protrusions 160 of the second teeth 120 are pushed to the back side of the first protrusions 150 of the first teeth 110. In this way, it can prevent the male teeth 100 from bursting (i.e., being damaged) due to mutual pressing of the teeth when bending inward.

[0031] As a preferred embodiment, grooves 133 for mounting of a cloth tape are provided on both sides of the male tooth base 130 in the first direction.

[0032] It can be understood that in this embodiment, the male teeth 100 of the male chain are connected together by a long cloth tape, which is referred to as a male teeth base tape. The male tooth base 130 of each male tooth 100 is used to connect to the male teeth base tape. A horizontal groove 133 is provided in the middle of each of two sides of the male tooth base 130 in the first direction. The male teeth base tape may be mounted in the grooves 133 through strong adhesive, so that the multiple male teeth 100 form a male chain. Of course, the male teeth base tape may alternatively be mounted in the grooves 133 through other connection methods.

[0033] As a preferred embodiment, chamfers or fillets 134 are provided on both side surfaces of the male tooth base 130 in the second direction.

[0034] Specifically, when the male chain bends inward, the male teeth 100 will press against each other inward, and the male tooth bases 130 will also press against each other in the second direction. Therefore, to prevent damage to the male tooth bases 130 due to mutual pressing as much as possible, chamfers or fillets 134 are provided on edges of both sides of each male tooth base 130 in the second direction, which can save more space for mutual approach of the male tooth bases 130. This arrangement can reduce damage to the male tooth bases 130 when the male chain bends inward.

[0035] As a preferred embodiment, the connecting portion 140 is arranged on a symmetry axis of the male tooth base 130 that extends in the second direction. A length of each of the first protrusion 150 and the second protrusion 160 in the second direction matches a length of the respective connecting portion 140. The connecting portion 140 is perpendicular to an upper surface of the male tooth base 130, and is also perpendicular to the first protrusion 150 and the second protrusion 160.

[0036] In this embodiment, the connecting portion 140 is vertically arranged on the upper surface of the male tooth base 130 and is located on the symmetry axis of the male tooth base 130 extending in the second direction. This arrangement facilitates coupling of the male chain and the female chain. Additionally, the length of each of the first protrusion 150 and the second protrusion 160 in the second direction is the same as the length of the connecting portion 140, which prevents mutual interference between adjacent male teeth 100.

[0037] As a preferred embodiment, curved guide surfaces 170 are provided on both sides of each of the first protrusion 150 and the second protrusion 160 in the second direction.

[0038] It can be understood that when the male chain is coupled with the female chain, the male teeth 100 slide in the inner cavities of the female chain for teeth. By providing curved guide surfaces 170 on both sides of each of the first protrusion 150 and the second protrusion 160 in the second direction, the sliding of the male chain becomes smoother and less likely to get stuck.

[0039] As a preferred embodiment, extension portions 180 are provided at both ends of each of the first protrusion 150 and the second protrusion 160 in the second direction. The extension portions 180 of each two adjacent male teeth 100 abut against each other, with the abutment surfaces 181 being smooth curved surfaces.

[0040] Further, another embodiment is provided herein. Specifically, based on the aforementioned embodiment, extension portions 180 are provided at both ends of each of the first protrusion 150 and the second protrusion 160 in the second direction, as specifically shown in FIGS. 3 and 4. The two ends of each of the first protrusion 150 and the second protrusion 160 are provided with extension portions 180 that extend beyond the respective connecting portion 140 in the length direction of the connecting portion 140, and adjacent extension portions 180 abut against each other. It should be noted that the abutment surfaces 181 are smooth curved surfaces. In this way, when the male chain bends inward and the adjacent extension portions 180 press against each other, the abutment surfaces 181, due to their smooth curved surface configuration, will force the first teeth 110 and the second teeth 120 to tilt in opposite directions. This configuration also prevents damage to the teeth caused by the first teeth 110 and the second teeth 120 pressing against each other.

[0041] As a preferred embodiment, each of the male teeth 100 is integrally formed by injection molding.

[0042] It can be understood that each male tooth 100 in the present application is injection-molded as a single piece, which not only improves the production efficiency of the male tooth 100 but also enhances its overall structural strength.

[0043] As a preferred embodiment, a ratio of a spacing between each two adjacent male teeth 100 to a length of each male tooth 100 in the second direction is specifically between 1 / 5 and 1 / 3.

[0044] Additionally, in this embodiment, when the male chain is coupled with the female chain and bends inward in a manner as specifically shown in the lower part of FIG. 2, the spacing between adjacent male teeth 100 of the male chain significantly increases, making it easy for the male teeth 100 to disengage from the inner cavities of the female chain for teeth, resulting in chain bursting. Therefore, in this embodiment, the spacing between adjacent male teeth 100 is reduced compared with the conventional technology. Specifically, the ratio of the spacing between each two adjacent male teeth 100 to a length of each male tooth 100 in the second direction is between 1 / 5 and 1 / 3. In this way, when the male chain bends outward, the change in distance between the male tooth bases 130 of the male teeth 100 is smaller, making it less likely for the male teeth 100 to disengage from the inner cavities of the female chain.

[0045] An anti-breakage slide zipper is further provided according to the present application, including a female chain and the aforementioned anti-breakage male chain. Therefore, the anti-breakage slide zipper having the anti-breakage male chain also provides all of the technical effects mentioned above, which will not be repeated herein.

[0046] Further, a garment including the aforementioned anti-breakage slide zipper is further provided according to the present application. Therefore, the garment having the anti-breakage slide zipper also provides all of the technical effects mentioned above, which will not be repeated herein.

[0047] It should be noted that, terms such as first and second in this specification are merely used to distinguish an entity from other entities, and do not require or imply that there are any such actual relationships or sequences between these entities.

[0048] The embodiments in the specification are described in a progressive manner, and description of each embodiment focuses on its difference from other embodiments. Same and similar parts among these embodiments may be referred to each other.

[0049] The embodiments of the present application are described above. The principle and implementation of the present application are illustrated by using specific embodiments herein. The above description of the embodiments is only used to facilitate understanding of the method and the core idea of the present application. It should be noted that, several improvements and modifications may be made by those skilled in the art to the present application without departing from the principle of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
