Description

Technical Field

[0001] The utility model relates to the technical field of zipper structures, in particular to a garment and a zipper thereof. Background Art

[0002] Zippers are divided into open zippers and closed zippers according to the opening and closing type of their lower ends. Open zippers are generally set on clothing. Open zippers are composed of two independent single-sided tooth chains, plugs and sockets, and pull heads. The plugs and sockets at the bottom of the two single-sided tooth chains can be separated. Closed zippers are generally used in the plackets of pants or skirts. Closed zippers refer to zippers in which two single-sided tooth chains are combined at the bottom through a bottom stop. The bottom ends of the two single-sided tooth chains cannot be separated at will. This type of zipper is generally used in the plackets of pants or skirts.

[0003] Generally, since the bottom of a closed zipper is closed and cannot be separated at will, when sewing a closed zipper onto an item, the cloth tape with the chain teeth and the zipper slider must be assembled first, and the slider must be slid during the sewing process to avoid the obstacles formed by the slider. This limits the sewing position of the item to which the closed zipper is installed and makes it difficult to adjust.

[0004] The resin closed-end zippers currently on the market generally have sliders that cannot be removed, and cannot be plugged in and out like open-end zippers. They are simply closed-end zippers that cannot be opened or closed. If the customer wants to replace the slider after the order is completed, or if an error occurs during the order production process and the wrong slider is installed, the current response is to cut off the zipper part, disassemble the zipper to let the slider fall out, causing the zipper to be scrapped, or to manually remove the top or bottom stop before replacing the slider, and then reinstall the top or bottom stop. These methods waste materials and increase costs. In addition, the sewing process of the entire closed-end zipper in the processing plant is complicated and time-consuming. Mechanized sewing is difficult and requires adjustment of the design.

[0005] Therefore, how to provide a garment and a zipper thereof to at least partially solve the above-mentioned drawbacks is a technical problem that those skilled in the art currently need to solve. Utility Model Content

[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0042] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside" and "outside" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation of the present invention.

[0043] The utility model aims to provide a garment and a zipper thereof, which solves the problem that the slider 400 cannot be replaced at any time, makes it convenient to remove and insert the slider 400 during replacement, and has the advantages of simple structure, convenient use and wide application range.

[0044] See also Figure 1 and Figure 3 To achieve the above-mentioned purpose, the utility model provides a zipper, including two cloth tapes 100, a bottom stop assembly 200, an upper stop assembly 300 and a slider 400, the two cloth tapes 100 are respectively provided with a first tooth chain 110 and a second tooth chain 120 that can mesh with each other, the first tooth chain 110 and the second tooth chain 120 both include a plurality of teeth 130 that are spaced from each other and arranged in sequence; the bottom stop assembly 200 includes a first bottom stop 210 disposed at the bottom of the first tooth chain 110 and a second bottom stop 220 disposed at the bottom of the second tooth chain 120, the first bottom stop 210 The upper stop assembly 300 includes a first upper stop 310 disposed at the top of the first tooth chain 110 and a second upper stop 320 disposed at the top of the second tooth chain 120; the pull head 400 can enter and disengage from the first tooth chain 110 along the first upper stop 310, so as to enable the first lower stop 210 and the second lower stop 220 and the first tooth chain 110 and the second tooth chain 120 to engage with each other, and the first lower stop 210 is provided with a stop block 211 to limit the pull head 400 from disengaging from the first lower stop 210 in the direction away from the first tooth chain 110.

[0045] It should be noted that, in the present embodiment, the first bottom stop 210 and the first top stop 310 are respectively located at the two ends of the first tooth chain 110, and the second bottom stop 220 and the second top stop 320 are respectively located at the two ends of the second tooth chain 120. It can be seen that the first bottom stop 210 and the first top stop 310 are arranged on the same cloth tape 100, and the difference in naming of the first top stop 310 and the second top stop 320 is only for the convenience of understanding the following text. The positions of the first top stop 310 and the second top stop 320 can be interchanged, and it is only necessary to adjust the height of the topmost tooth 130 of the tooth chain accordingly.

[0046] See also Figure 5 , Figure 6 and Figure 7 Specifically, the closed-end zipper is modularized, that is, it is divided into two cloth tapes 100 arranged on the left and right, and the slider 400 is inserted from the first upper stop 310 at the upper end of the single-side cloth tape 100, and is pulled along the first tooth chain 110 to the bottom end of the first lower stop 210 until it fits with the stopper 211 provided on the first lower stop 210, and the slider 400 is limited, and after the second lower stop 220 at the bottom of the second tooth chain 120 is inserted into the slider 400, the slider 400 is pulled so that the first lower stop 210 and the second lower stop 220 are closed and the slider 400 is closed. The first tooth chain 110 and the second tooth chain 120 are meshed with each other, and then the first upper stop 310 at the top of the first tooth chain 110 and the second upper stop 320 at the top of the second tooth chain 120 enter the slider 400 to limit the upward separation of the slider 400. When the slider 400 is disassembled, the installation steps of the slider 400 are reversed. The detachable slider 400 can be easily removed or inserted during the replacement process of the slider 400, and has the advantages of simple structure, convenient use and wide application range.

[0047] Preferably, the slider 400 is provided with a accommodating cavity 410, which includes two inlet ends 411 located at the top of the slider 400 and an outlet end 412 located at the bottom of the slider 400, and the outlet end 412 is used for the teeth 130 entering the accommodating cavity 410 through the two inlet ends 411 to engage with each other, so as to connect the first tooth chain 110 and the second tooth chain 120.

[0048] It can be understood that the teeth 130 in the first tooth chain 110 and the second tooth chain 120 respectively enter the accommodating cavity 410 of the slider 400 along the adjacent inlet ends 411, and then as the slider 400 moves, the corresponding teeth 130 move to the outlet end 412 of the accommodating cavity 410. As the teeth 130 gradually move from the inlet end 411 to the outlet end 412, the horizontal width of the accommodating cavity 410 also gradually decreases, so that the teeth 130 at the two inlet ends 411 engage with each other during the movement, thereby finally realizing the connection between the first tooth chain 110 and the second tooth chain 120.

[0049] It should be noted that, in the present embodiment, a protrusion is provided at the end of each tooth 130, and a groove matched with the protrusion is formed between the upper and lower adjacent teeth 130, so that the protrusion and the groove at the same height can be snapped together. At the same time, the surfaces of the protrusion and the groove are both smooth structures, so that when the pull head 400 is pulled downward, the separation column inside it can separate the snapped protrusion and groove.

[0050] See also Figure 2 Preferably, the second bottom stop 220 is provided with a first plug connector 221 and a second plug connector 222 at intervals along the moving direction of the slider 400, the first bottom stop 210 is provided with a first slot 212 and a second slot 213 which can respectively cooperate with the first plug connector 221 and the second plug connector 222 in a clearance manner, and the second bottom stop 220 and the first bottom stop 210 are provided with protrusions 230 on the opposite sides, and the horizontal distance between the outermost sides of the two protrusions 230 is greater than the horizontal distance between the inner sides of the outlet end 412, so that when the slider 400 passes through the two protrusions 230, it can drive the second bottom stop 220 and the first bottom stop 210 to engage with each other.

[0051] The second bottom stop 220 is provided with a first plug connector 221 and a second plug connector 222 at intervals along the moving direction of the slider 400. The ends of the first plug connector 221 and the second plug connector 222 are both bent protrusion structures extending obliquely downward, which are used to facilitate the second bottom stop 220 to be snapped into the first slot 212 and the second slot 213 of the first bottom stop 210 after the second bottom stop 220 is inserted into the slider 400. The first plug connector 221 and the second plug connector 222, which are not completely the same in appearance, can prevent the first bottom stop 210 and the second bottom stop 220 from being misaligned.

[0052] See also Figure 8 and Fig. 9 In addition, the bottom of the second bottom stop 220 is a tapered structure, which is convenient for the second bottom stop 220 to be inserted into the slider 400, and the tapered structure is adapted to the corresponding structure in the accommodating cavity 410, so that the second bottom stop 220 is inserted into the appropriate position. The second bottom stop 220 and the first bottom stop 210 have a small angle with the vertical direction on the opposite side, which is convenient for adapting to the internal structure of the slider 400, and the side is provided with a block-shaped protrusion 230, and the horizontal distance between the outermost sides of the two protrusions 230 is greater than the horizontal distance between the inner sides of the outlet end 412, that is, during the meshing process, the combined width of the protrusions 230 is slightly greater than the width of the inner side of the outlet end 412 of the slider 400, so that the accommodating cavity 410 of the slider 400 squeezes the protrusions 230 on both sides, so that the second bottom stop 220 and the first bottom stop 210 are more tightly meshed to avoid the occurrence of chain bursting.

[0053] Preferably, the second plug connector 222 is located on the side of the first plug connector 221 away from the second toothed chain 120 , and the size of the second plug connector 222 is larger than the size of the first plug connector 221 and the first slot 212 to prevent the second plug connector 222 and the first slot 212 from being stuck together.

[0054] Among them, the second plug connector 222 is preferably located at the bottom of the second lower stop 220, and the size of the second plug connector 222 is larger than the size of the first plug connector 221 and the first slot 212, which can prevent the second plug connector 222 from being inserted into the first slot 212, so that the first plug connector 221 and the second plug connector 222 are respectively engaged with the corresponding first slot 212 and second slot 213. It should be noted that because the block 211 has a limiting effect on the lowest position of the slider 400, the situation where the first plug connector 221 is inserted into the second plug connector is avoided.

[0055] Preferably, the tops of the first top stop 310 and the second top stop 320 are at the same height, and the sum of the widths of the first top stop 310 and the second top stop 320 is greater than the minimum width of the outlet end 412 to prevent the slider 400 from being separated from the first top stop 310 and the second top stop 320 at the same time.

[0056] In this embodiment, it is preferred that the tops of the first top stop 310 and the second top stop 320 are at the same height, and the bottoms of the first top stop 310 and the second top stop 320 are spaced apart from the uppermost teeth 130 of the first tooth chain 110 and the second tooth chain 120, respectively. Due to the staggered engagement of the teeth 130 on both sides, the bottom heights of the first top stop 310 and the second top stop 320 are different. It is preferred that the height of the teeth 130 adjacent to the first top stop 310 is lower than the height of the teeth 130 adjacent to the second top stop 320. The longer first top stop 310 can prevent the slider 400 from easily detaching when it is located on one side.

[0057] Preferably, the two protrusions 230 are arranged at the same height, and both ends of the two protrusions 230 along the moving direction of the slider 400 are provided with rounded structures so that the protrusions 230 enter the inlet end 411 .

[0058] It is understandable that the two protrusions 230 are preferably arranged at the same height. The rounded structures at both ends of the protrusion 230 facilitate its entry into the inlet end 411 and escape along the outlet end 412 , while reducing the wear of the protrusion 230 .

[0059] Preferably, the stopper 211 is a block-shaped structure, and the stopper 211 is provided with an upper end surface for contacting the bottom of the slider 400 , and the upper end surface is arranged horizontally.

[0060] See also Figure 4It should be noted that the stopper 211 is preferably located on the side of the tape 100 away from the handle. The stopper 211 of the block structure arranged on the inner side can abut against the bottom of the slider 400 to limit the detachment of the slider 400, and the end surface of the stopper 211 abutting against the slider 400 is arranged horizontally, so that the slider 400 is in a horizontal state when it is at the lowest point. The stopper 211 is only located at the first bottom stop 210, so that the second bottom stop 220 does not need to be aligned with the first bottom stop 210, and can be directly inserted into the inside of the slider 400.

[0061] Preferably, all corners of the first upper stop 310 and the second upper stop 320 are rounded, and a first arc surface and a second arc surface in contact with the outer side of the tooth 130 are provided from top to bottom between the inlet end 411 and the outlet end 412, and the first arc surface and the second arc surface are tangent to each other.

[0062] In this embodiment, a first arc surface and a second arc surface in contact with the outer side of the teeth 130 are provided from top to bottom between the inlet end 411 and the outlet end 412. The tangent first and second arc surfaces facilitate movement of the teeth 130 inside the teeth 130, thereby reducing resistance to movement of the slider 400.

[0063] Preferably, the first bottom stop 210 and the stopper 211 are an integrated structure.

[0064] Among them, it is preferred that the lower stop and the stopper 211 are an integrated structure. The first lower stop 210 and the stopper 211 can also be set as a split structure according to actual conditions. No specific limitation is made here, as long as the above purpose can be achieved.

[0065] Preferably, the slider 400 is further provided with a handle, and the handle is used to drive the slider 400 to move.

[0066] It is understandable that the slider 400 is also provided with a handle for driving the slider 400 to move. The specific shape and structure of the handle can be adjusted according to actual conditions and is not specifically limited here, as long as the above purpose can be achieved.

[0067] In addition, it should be noted that the closed-end zipper is mostly used on the pockets of clothing. The conventional closed-end zipper pocket sewing cannot be automatically sewn and needs to be completed in multiple steps, and the slider 400 cannot be replaced. When sewing a conventional zipper, the zipper is meshed together, and the tape head of the upper stop part needs to be sewn together first, and then the left and right sides of the tape 100 are sewn. When sewing the tape 100 near the slider 400, the slider 400 needs to be pulled to the position where the tape 100 has been sewn before continuing to sew. The demand for automated sewing cannot be met, and the sewing effect cannot be guaranteed, and the quality is uneven.

[0068] See also Fig.10 and Fig.11The zipper provided in this embodiment is designed in modular form so that it can meet the automation requirements of sewing pockets on clothing after disassembly. The left and right cloth tapes 100 are separated and placed on the templates automatically sewn in the factory for machine sewing. After the left and right cloth tapes 100 and the front and rear cloths are sewn on the fixed template positions respectively, the slider 400 is inserted. There are fewer sewing steps, and the production efficiency is improved by automatically sewing on the template.

[0069] A garment comprises a plurality of pockets, wherein the pockets are provided with the above-mentioned zipper, and also has the beneficial effects of the above-mentioned zipper.

[0070] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0071] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0072] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the utility model.
