The term "and / or" used in the specification of this application includes any and all combinations of one or more of the related listed items.
[0034] Please refer to Figures 1 to 3 , this application provides a pull tab 100 for a double-open zipper. The pull tab 100 for the double-open zipper is applied to items such as clothing, luggage, shoes and hats, etc., and is mainly used as an auxiliary component for slidingly opening or closing the items. The structure of the pull tab 100 for the double-open zipper is improved to make it closer to the ergonomic design, reduce the connection structure, so as to increase the structural stability, make it not easily damaged, and improve its service life, the user's hand feeling and the operation experience of the pull tab.
[0035] Specifically, as Figure 1 and Figure 2 shown, the pull tab 100 for the double-open zipper at least includes a tab body 10. The tab body 10 is provided with a chain slot 12 for accommodating the chain teeth 11 and allowing the chain teeth 11 to slide; the tab body 10 is a single component and has opposite top surface 30 and bottom surface 20. The middle of the bottom surface 20 has a first recessed area 21, and the first recessed area 21 is smoothly transitioned with the surrounding parts; the top surface 30 has a second recessed area 31. Along the working movement direction of the pull tab, the two opposite sides of the second recessed area 31 are raised first ridge part 32 and second ridge part 33.
[0036] It should be noted that the pull tab 100 for a double-slider zipper in the prior art is generally composed of two separate parts of teeth, has multiple connection positions, and has obvious edges and corners and other accessory parts on the outer periphery of the pull tab. The user's hand feeling and operation experience are poor, and the pull tab is also relatively easy to scrape and damage. In this application, the pull tab body 10 is set as a single part, reducing its connection structure, thereby increasing its structural stability, avoiding excessive connection parts and being easily damaged, increasing the service life of the pull tab 100 for a double-slider zipper, and the first recessed area 21 on the bottom surface 20 of the pull tab body 10 is smoothly transitioned with the surrounding parts. There are no obvious edges or accessory parts on the pull tab body 10, improving the user's hand feeling; at the same time, the first ridge 32 and the second ridge 33 on its top surface 30 are convex, and the middle is the second recessed area 31. Such a structural setting is closer to the ergonomic design, and it is more convenient for the user to operate.
[0037] Here, the setting of the pull tab body 10 as a single part removes the structure of connecting multiple parts in the existing pull tab, realizing the lightweight production and application of the pull tab body 10, and further improving the user's use experience.
[0038] Preferably, the number of teeth 11 of the pull tab 100 for a double-slider zipper is set to two. The chain slot 12 formed by the cooperation of the two teeth 11 can be engaged with the chain tape 201 so that the pull tab 100 for a double-slider zipper can be installed on the double-slider zipper.
[0039] Furthermore, the pull tab body 10 includes an upper plate 13 and a lower plate 14 arranged opposite to each other, and a support core 15 connected between the upper plate 13 and the lower plate 14. The chain slot 12 is located between the upper plate 13 and the lower plate 14, and both the upper plate 13 and the lower plate 14 are flat structures. Both the upper plate 13 and the lower plate 14 are set as flat structures, which can make the thickness of the pull tab body 10 thinner, make its weight lighter without affecting the strength of the pull tab body 10, and also have a support core 15 structure for supporting and connecting the upper plate 13 and the lower plate 14, making the structure more stable and firm and not easily deformed.
[0040] Preferably, the pull tab body 10 has a smooth outer peripheral contour. Such a structure can avoid obvious edges and corners on the pull tab body 10 and improve the user's hand feeling when using it.
[0041] Such as Figure 1As shown, in one embodiment, x and y are respectively the length direction and width direction of the lower pull head 100 for a double-slider zipper. The pull head body 10 has a height direction z extending from the top surface 30 to the bottom surface. The height of the pull head body 10 is less than the length and width of the pull head body 10. In this way, the lower pull head 100 for the double-slider zipper is in a flat state, with a reduced thickness, avoiding the sense of foreign objects during actual use, and while reducing the weight of the pull head body 10, increasing the contact area between the pull head body 10 and the chain tape 201, making the connection between the pull head body 10 and the chain tape 201 more stable, so that it is not easily disengaged or damaged, improving the user experience.
[0042] Please continue to refer to Figure 1 and Figure 2 As shown in and, the first recessed area 21 is integrally arranged as an arc surface structure. The arc surface structure is more in line with the ergonomic design, facilitating the user to press and push the pull head body 10 to realize the opening and closing functions of the double-slider zipper 200, and the arc surface structure can avoid generating burrs and is more beautiful. At the same time, the pull head body 10 omits structures such as the connected pull tab and cap, enabling the product to be as light and thin as possible while ensuring strength, so as to improve the adaptability of the lower pull head 100 for the double-slider zipper.
[0043] Exemplarily, the first ridge 32 and the second ridge 33 are adjacent to the edges of the corresponding sides of the top surface 30, making the second recessed area 31 have a larger contact area, facilitating user operation, and the opposite sides of the two are smoothly transitioned to the edge of the top surface 30, which can avoid generating redundant parts on the lower pull head 100 for the double-slider zipper, so as to reduce scratching and increase the touch of the structure.
[0044] Furthermore, grooves 34 are respectively formed on the opposite sides of the first ridge 32 and the second ridge 33. The groove 34 structure can be used as a force application part to prevent the user from slipping when pulling the lower pull head, and convex ribs 35 are respectively provided on the top sides of the openings of the grooves 34, enabling the user to directly act on the convex ribs 35 to pull the lower pull head 100 for the double-slider zipper, further increasing the convenience of the structure during use.
[0045] The present application also provides the following technical solutions:
[0046] A double-slider zipper 200 includes chain tapes 201 and a pull head 202. Among them, there are two chain tapes 201 with mutually engaged chain teeth 11; the pull head 202 includes an upper pull head and a lower pull head that slide along the chain tapes 201, and the lower pull head adopts the lower pull head 100 for the double-slider zipper in any of the above embodiments. The double-slider zipper 200 is not provided with a lock, making it more in line with the use scenario of the lower pull head 100 for the double-slider zipper, and overall improving the comfort of the user during use.
[0047] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0048] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application shall be subject to the appended claims.
