Description

Technical Field

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

[0002] A zipper consists of teeth, a slider, and top and bottom stops (front and back stops) or locking mechanisms. The teeth are the key component, directly determining the zipper's lateral pulling strength. Generally, a zipper has two straps, each with a row of teeth, arranged alternately. The slider grips the teeth on both sides, and by sliding along the pull tabs, the teeth on both sides can be engaged or disengaged.

[0003] In existing solutions, the spacing between adjacent teeth on the same row of chain belts and the spacing between adjacent teeth on another row of chain belts are subject to strict requirements. The error range cannot be too large, otherwise the teeth on both sides will not be able to mesh with each other. With the accumulation of errors, the two chain belts will be of different lengths. In addition, the size of each tooth in the two rows of chain belts must also be equal, which means that there is no universality between chain teeth of different sizes. Summary of the Invention

[0004] The purpose of this application is to provide a zipper that solves at least one of the aforementioned technical problems.

[0005] A zipper, comprising:

[0006] The first chain tooth has a first slot.

[0007] The first chain cloth, with several first chain teeth respectively connected along the length of the first chain cloth;

[0008] The second chain tooth has a first locking element that can engage with the first slot.

[0009] The second chain fabric, corresponding to the position of the first chain tooth, has several second chain teeth connected to the length direction of the second chain fabric;

[0010] The zipper head has two ends connected to the first chain fabric and the second chain fabric respectively. The zipper head can make the first locking piece engage or disengage from the first locking slot.

[0011] The lower stop is connected to the first and / or second chain teeth at the end.

[0012] Its beneficial effects are: the relative position error of the first and second chain teeth can be appropriately improved, the zipper can be pulled up normally when the first clip engages with the first slot, and the zipper is not easily separated from the first and second chain teeth by the pulling force on both sides; it changes the problem in traditional zippers where errors accumulate when the chain teeth are mismatched, eventually resulting in the chain fabric being of different lengths and unsightly, thus improving the fault tolerance rate compared to traditional zippers.

[0013] In some embodiments, the first slot includes: a first connecting portion, a first locking end, and a second locking end;

[0014] The first connecting part is connected to the first locking end and the second locking end at its two ends, respectively.

[0015] The first slot has an opening for the first card to pass through, and the size of the opening gradually decreases from one end to the other.

[0016] Its beneficial effect is that the size of the opening gradually decreases from one end to the other, which makes it less likely for the first card to separate from the first card slot when the first card is engaged with the first card slot, thus improving the stability and firmness of the engagement between the two.

[0017] In some embodiments, the shape of the first card can match the shape of the first card slot;

[0018] The first card has a first matching end and a second matching end at its two ends, respectively. The shape of the first matching end can match the shape of the first locking end, and the shape of the second matching end can match the shape of the second locking end.

[0019] In some implementations, the size of the first clip gradually increases from one end to the other.

[0020] In some implementations, a separation structure is provided inside the zipper pull;

[0021] The lower end of the separation structure is shaped to match the shape of the first chain tooth and allows the first chain tooth to pass through.

[0022] The upper end of the separation structure is shaped to match the shape of the second chain tooth and allows the second chain tooth to pass through;

[0023] The size of the slider gradually decreases from one end to the other.

[0024] Its beneficial effects are: the separation structure allows the first chain tooth to separate from the engaged second chain tooth when the zipper is pulled down; the gradual decrease in size of the zipper from one end to the other makes it easier to squeeze the second chain tooth when the zipper is pulled up, so that the first chain tooth and the second chain tooth can engage with each other.

[0025] In some embodiments, the separation structure includes a connector with its two ends located at the inner ends of the pull head;

[0026] The lower end of the connector is provided with a second locking element, the shape of which can match the first locking slot;

[0027] The upper end of the connector is provided with a second slot, the shape of which can match the first connector.

[0028] In some implementations, the zipper pull also includes a first opening and a second opening;

[0029] The first opening is located on the right side of the zipper head, for the first chain cloth to pass through;

[0030] The second opening is located on the left side of the zipper head, for the second chain cloth to pass through.

[0031] In some implementations, the first opening is parallel to the bottom of the slider, and the second opening is inclined and parallel to the top of the slider.

[0032] In some implementations, the lower stop includes

[0033] A passage for the first and second chain teeth to pass through;

[0034] The third opening is located on the left side of the lower stop and is used to allow the second chain fabric to pass through.

[0035] A protrusion is located at the top of the inner part of the lower stop.

[0036] In some embodiments, a groove is provided on the second tooth closest to the bottom stop, the shape of which matches the shape of the protrusion, and the protrusion can engage with the groove. Attached Figure Description

[0051] like Figure 1As shown,

[0052] A zipper, comprising:

[0053] First chain tooth 1, the first chain tooth 1 is provided with a first slot 11;

[0054] The first chain cloth 2, and several first chain teeth 1 are respectively connected to the length direction of the first chain cloth 2;

[0055] The second chain tooth 3 is provided with a first locking element 31, which can engage with the first locking slot 11.

[0056] The second chain fabric 4, corresponding to the position of the first chain tooth 1, has several second chain teeth 3 connected to the length direction of the second chain fabric 4 respectively;

[0057] The zipper head 5 has two ends connected to the first chain cloth 2 and the second chain cloth 4 respectively. The zipper head 5 can make the first locking piece 31 and the first locking groove 11 engage or disengage.

[0058] The lower stop 6 is connected to the first chain tooth 1 and / or the second chain tooth 3 at the end.

[0059] Its beneficial effects are: the relative position error of the first chain tooth 1 and the second chain tooth 3 can be appropriately improved, and the zipper can be pulled up normally when the first clip 31 engages with the first slot 11. Moreover, the zipper is not easily separated from the first chain tooth 1 and the second chain tooth 3 due to the pulling force on both sides. It changes the problem in traditional zippers where errors accumulate when the chain teeth are mismatched, eventually resulting in the chain fabric being of different lengths and unsightly. Compared with traditional zippers, it improves the fault tolerance rate.

[0060] Especially in traditional zippers, there are strict requirements for the spacing between adjacent teeth on the same chain row, and the size of the teeth also follows a uniform standard. In the solution of this application, within the range that can be observed by the naked eye, the sizes of the first tooth 1 and the second tooth 3 do not need to match perfectly; they can be one large and one small or equal.

[0061] Preferably, any adjacent first chain teeth 1 have the same spacing; any adjacent second chain teeth 3 have the same spacing.

[0062] like Figure 2 As shown,

[0063] Preferably, the first slot 11 includes: a first connecting part 111, a first locking end 112, and a second locking end 113;

[0064] The first connecting part 111 is connected to the first locking end 112 and the second locking end 113 at its two ends respectively;

[0065] The first slot 11 is provided with an opening 114 for the first card 31 to pass through, and the size of the opening 114 gradually decreases from one end to the other.

[0066] The first locking end 112 and the second locking end 113 are respectively rounded to facilitate the engagement or disengagement of the first slot 11 and the first card 31.

[0067] Its beneficial effect is that the size of the opening 114 gradually decreases from one end to the other, which makes it less likely for the first card 31 to separate from the first card slot 11 when the first card 31 is engaged with the first card slot 11, thus improving the stability and firmness of the engagement between the two.

[0068] like Figure 4 As shown,

[0069] Preferably, the shape of the first card 31 can match the shape of the first card slot 11;

[0070] The first locking piece 31 has a first matching end 32 and a second matching end 33 at its two ends respectively. The shape of the first matching end 32 can match the shape of the first locking end 112, and the shape of the second matching end 33 can match the shape of the second locking end 113.

[0071] The first matching end 32 and the second matching end 33 are rounded to facilitate the engagement or disengagement of the first card slot 11 and the first card 31.

[0072] Preferably, the size of the first card 31 gradually increases from one end to the other.

[0073] like Figure 7 As shown,

[0074] Preferably, the slider 5 is provided with a separation structure 51;

[0075] The lower end of the separation structure 51 is shaped to match the shape of the first chain tooth 1 and allows the first chain tooth 1 to pass through.

[0076] The upper end of the separation structure 51 is shaped to match the shape of the second chain tooth 3 and allows the second chain tooth 3 to pass through.

[0077] The size of the slider 5 gradually decreases from one end to the other.

[0078] Its beneficial effects are: the separation structure 51 enables the first chain tooth 1 to separate from the engaged second chain tooth 3 when the zipper head 5 is pulled down; the size of the zipper head 5 gradually decreases from one end to the other, which makes it easier to squeeze the second chain tooth 3 when the zipper head 5 is pulled up, so that the first chain tooth 1 and the second chain tooth 3 are engaged with each other.

[0079] Preferably, the separation structure 51 includes a connector 511, with both ends of the connector 511 located at the inner ends of the pull head 5.

[0080] The lower end of the connector 511 is provided with a second locking piece 512, the shape of which can match the first locking slot 11;

[0081] The upper end of the connector 511 is provided with a second slot 513, the shape of which can match the first slot 31.

[0082] Preferably, the zipper pull 5 further includes a first opening 52 and a second opening 53;

[0083] The first opening 52 is located on the right side of the pull head 5, for the first chain cloth 2 to pass through;

[0084] The second opening 53 is located on the left side of the pull head 5, for the second chain cloth 4 to pass through.

[0085] Preferably, the first opening 52 is parallel to the bottom of the slider 5, and the second opening 53 is inclined and parallel to the top of the slider 5.

[0086] like Figure 2 , 6 As shown in Figure 8,

[0087] Preferably, the lower limit 6 includes

[0088] Channel 61 through which the first chain tooth 1 and the second chain tooth 3 pass;

[0089] The third opening 62 is located on the left side of the lower stop 6 and is used to allow the second chain cloth 4 to pass through.

[0090] Protrusion 63 is located at the top of the interior of the lower stop 6.

[0091] Preferably, a groove 34 is provided on the second chain tooth 3 closest to the lower stop 6. The shape of the groove 34 matches the shape of the protrusion 63, and the protrusion 63 can engage with the groove 34.

[0092] like Figure 8 As shown, the operator can squeeze point a to disengage the protrusion 63 from the groove 34, thus removing the first chain tooth 1 and the second chain tooth 3 from the lower stop 6.

[0093] It should be noted that the shape of the first card slot 11 can be arbitrary, and correspondingly, the shape of the first card piece 31 can also be arbitrary, but the shape of the first card piece 31 needs to match the first card slot 11. In this embodiment, the outer surfaces of the first card piece 31 and the first card slot 11 are arcs, and further, their shapes can resemble teardrops.

[0094] The shapes of the protrusion 63 and the groove 34 can be arbitrary, as long as the shape of the protrusion 63 matches the shape of the groove 34. In this embodiment, the protrusion 63 is preferably a circular protrusion, and the groove 34 is preferably a circular groove.

[0095] When the zipper is pulled up, the zipper head 5 moves upward relative to the lower stop 6, and the zipper head 5 squeezes the second zipper tooth 3, so that the second zipper tooth 3 engages with the first zipper tooth 1;

[0096] When the zipper is pulled down, the zipper head 5 moves downward relative to the lower stop 6. The separation structure 51 inside the zipper head 5 separates the second zipper tooth 3 from the first zipper tooth 1. The upper end of the separation structure 51 guides the second zipper tooth 3, and the lower end of the separation structure 51 guides the first zipper tooth 1.

[0097] 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. In this case, all details can be replaced with equivalent elements, and the materials, shapes, and sizes can also be arbitrary.
