Description

Technical Field

[0001] The present application relates to the technical field of clothing, and in particular to a double-sided slider and a double-opening zipper. Background Art

[0002] A double-open zipper is a type of zipper that can be opened at both ends and has two pullers. Double-open double-head zippers are widely used because they are more practical than single-open zippers. In the prior art, a puller usually includes a pull seat and a pull tab movably connected to the pull seat. By holding the pull tab, the pull seat can be driven to move along the zipper to achieve the zipping of the zipper. This type of puller includes not only a pull tab, but also a cap and other structures. It has many parts, complex production steps, and high production costs.

[0003] Usually, the two sliders of a double-opening zipper are two sliders with the same structure but opposite directions. However, the two sliders of a double-opening zipper have very different usage scenarios during their use: such as the degree of need for the self-locking function, the direction in which they are usually pulled and closed, the ergonomics required for sliding, etc. Specifically, the need for pulling and closing the lower slider is less than that for the upper slider, and the need for its self-locking function is low.

[0004] The functions and requirements of the lower slider in the double-opening double-head zipper are lower than the functions that the slider itself can achieve in the prior art, resulting in redundant functions of the lower slider. Therefore, a lower slider with a matching production cost and functional requirements can be provided to reduce the production cost compared with the slider in the prior art. Summary of the invention

[0005] Based on this, it is necessary to provide a double-sided slider and a double-opening zipper to address the problem of high production cost of the lower slider in the double-opening double-head zipper.

[0029] See also Figure 1 , Figure 1 A structural schematic diagram of a double-opening zipper 100 in an embodiment of the present application is shown. A double-opening zipper 100 provided in an embodiment of the present application includes a first toothed chain tape 110, a second toothed chain tape 120, an upper slider 130 and a double-sided slider 140 as described in any of the following embodiments.

[0030] like Figure 1 As shown, the first fastener belt 110 includes a first extension belt 111 and a row of first coupling elements 112 attached to the coupling edge of the first extension belt 111. The second fastener belt 120 includes a second extension belt 121 and a row of second coupling elements 122 attached to the coupling edge of the second extension belt 121, and the second coupling elements 122 and the first coupling elements 112 are arranged alternately.

[0031] like Figure 1 As shown, the upper pull head 130 is configured to be able to move along the operating axis (at Figure 1 The first and second tooth chain belts 110 and 120 reciprocate relative to each other (in the up and down directions), and during the movement, the second connecting chain teeth 122 and the first connecting chain teeth 112 are driven to alternately engage or disengage, so that the first and second tooth chain belts 110 and 120 are attached to or detached from each other.

[0032] like Figure 1As shown, the double-sided slider 140 is configured to be able to reciprocate along an operating axis relative to the first and second toothed chain belts 110 and 120, wherein the operating axis of the double-sided slider 140 is parallel to and opposite to the operating axis of the upper slider 130, and during the movement, it drives the second connecting chain teeth 122 and the first connecting chain teeth 112 to engage or disengage in an alternating manner, so that the first and second toothed chain belts 110 and 120 are attached to or detached from each other.

[0033] Combination Figures 2 to 4 As shown, Figures 2 to 4 A structural schematic diagram of a double-sided slider 140 in an embodiment of the present application is shown. An embodiment of the present application provides a double-sided slider 140, which includes a top plate 141, a bottom plate 142 and a support core 143 connected between the top plate 141 and the bottom plate 142. In one embodiment, the top plate 141 is provided with a top edge stopper 1414 arranged toward the bottom plate 142, and the bottom plate 142 is provided with a bottom edge stopper 1421 arranged toward the top plate 141 and aligned with the top edge stopper 1414. The top edge stopper 1414 and the bottom edge stopper 1421 are arranged opposite to each other and spaced apart, and the space between the top edge stopper 1414 and the bottom edge stopper 1421 is used for the first extension belt 111 or the second extension belt 121 to pass through.

[0034] like Figure 2 and Figure 3 As shown, the end surface of the top plate 141 facing away from the bottom plate 142 is concavely provided with a traction groove 1411. When a foreign object (such as a finger) is pressed against the traction groove 1411 and a force is applied in the direction of the offset axis of the double-sided slider 140, at least part of the side walls of the traction groove 1411 are subjected to abutment force and the bottom wall part of the traction groove 1411 is subjected to friction force. At this time, when the foreign object moves, under the action of the traction groove 1411, the double-sided slider 140 will move synchronously with the foreign object, thereby realizing pushing or pulling the double-sided slider 140 by pressing the traction groove 1411 to realize the movement of the double-sided slider 140, thereby meeting the use scenario of the lower slider of the double-opening zipper 100.

[0035] like Figure 3 As shown, in one embodiment, the bottom wall of the focusing groove 1411 is a concave arc structure, and the side wall of the focusing groove 1411 and the bottom wall of the focusing groove 1411 are smoothly transitioned to make it more convenient to press the focusing groove 1411. Figure 2 and Figure 3 As shown, the side walls and bottom walls of the force-carrying groove 1411 are ergonomically-adapted contoured grooves, which are adapted to the curvature of the fingertips of the human body to facilitate finger pressing, thereby improving the comfort of the user during use.

[0036] like Figures 1 to 3As shown, the double-sided slider 140 also includes an extension portion 144 extending from one end of the top plate 141. In one embodiment, the extension portion 144 extends along the plane where the top plate 141 is located. Compared with the traditional lower slider, it is flatter and simplifies the additional appearance structure to make the overall structure more simple, comfortable and lightweight.

[0037] In this embodiment, the top plate 141, the bottom plate 142, the support core 143 and the extension portion 144 are an integrated structure, and illustratively, they can be integrally formed by injection molding to reduce the number of production steps and production costs.

[0038] In one embodiment, the extension portion 144 is provided with a hanging hole 145 extending from the top plate 141 to the bottom plate 142. The double-sided slider 140 further includes a webbing 146 detachably provided in the hanging hole 145. The double-sided slider 140 provided in the present application has two usage modes: without hanging the webbing 146 and with hanging the webbing 146. Figure 1 and Figure 2 In the embodiment shown, the webbing 146 is disposed in the hanging hole 145, so that the double-sided slider 140 is driven to move in the direction of the operating axis by pulling the webbing 146; Figure 3 and Figure 4 In the embodiment shown, the double-sided pull head 140 does not include the webbing 146. At this time, the double-sided pull head 140 is driven to move in the direction of the operating axis by applying force to the force groove 1411. Figure 1 As shown, in this embodiment, the extension portion 144 is located at one end of the top plate 141 away from the upper slider 130 , so that the webbing 146 drives the entire double-sided slider 140 to move in a direction away from the upper slider 130 .

[0039] like Figure 2 and Figure 3 As shown, in one embodiment, the support core 143 is connected to the end surface of the top plate 141 facing the bottom plate 142 and is located at one end close to the extension portion 144. The support core 143 and the extension portion 144 are both located at one end of the top plate 141 in a direction corresponding to the staggered engagement of the second connecting chain teeth 122 and the first connecting chain teeth 112 when the double-sided slider 140 moves, so that the two side walls of the support core 143 can guide the detached second connecting chain teeth 122 and the first connecting chain teeth 112 to enter the interior of the double-sided slider 140 and engage with each other.

[0040] like Figure 2 and Figure 3As shown, in one embodiment, the top plate 141 also includes a first force bevel 1412, which is located at one end of the top plate 141 close to the extension portion 144, and the first force bevel 1412 is inclined at a downward slope from a position close to the force groove 1411 to the edge of the top plate 141, so that an external object (such as a finger) can apply force to the first force bevel 1412 to push the double-sided slider 140 toward the direction close to the upper slider 130.

[0041] In one embodiment, the top plate 141 also includes a second force bevel 1413, which is located at one end of the top plate 141 away from the extension portion 144, and the second force bevel 1413 is inclined at a downward slope from a position near the force groove 1411 to the edge of the top plate 141, so that an external object (such as a finger) can apply force to the second force bevel 1413 to push the double-sided slider 140 in a direction away from the upper slider 130.

[0042] like Figure 4 As shown, in one embodiment, an end surface of the bottom plate 142 facing away from the top plate 141 is provided with a logo groove 1422 for placing or engraving a brand and / or category logo.

[0043] The double-sided slider 140 provided in the above scheme is provided with a force groove 1411 on the top plate 141, so that foreign objects can drive the double-sided slider 140 to move by abutting against the side walls of the force groove 1411 and rubbing the bottom wall of the force groove 1411, thereby realizing pushing or pulling the double-sided slider 140 by pressing the force groove 1411. An extension portion 144 with a hanging hole 145 is also provided at one end of the top plate 141, so that the double-sided slider 140 can be hung with a webbing 146, so that the double-sided slider 140 can be driven to move in the direction of the operating axis by pulling the webbing 146, so that the double-sided slider 140 can have two usage modes: without hanging the webbing 146 and with hanging the webbing 146. The double-sided slider 140 provided in the present solution can be integrally formed, and the functions required by the lower slider can be realized without the need for a cap, a pull tab, or other structures. It has fewer parts, simpler production steps (such as integrally formed), and lower production costs, and can be used in two modes: without hanging the webbing 146 and with hanging the webbing 146, and has a wide range of applications.

[0044] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, 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, they should be considered to be within the scope of this specification.

[0045] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
