Description

Technical Field

[0001] This utility model relates to the technology of zippers, and in particular to a zipper slider. Background Technology

[0002] A typical zipper usually consists of a zipper chain consisting of a pair of zipper tapes on the left and right sides and a zipper chain consisting of a zipper tooth column mounted on the zipper tapes, and a zipper pull mounted on the zipper chain and opening or closing the zipper tooth column by sliding the zipper pull on the zipper chain.

[0003] In existing technology, a zipper pull includes a first wing plate and a second wing plate (equivalent to an upper wing plate and a lower wing plate) facing each other with a gap between them, a guide post connecting the first wing plate and the second wing plate, and a pair of flanges (or vice versa) positioned opposite each other in the width direction of the first wing plate at opposite ends. Typically, the pair of flanges are positioned opposite each other at the opposite outer ends of the first wing plate in the width direction, with the outer ends of the flanges aligned with the outer ends of the first wing plates. Considering the aesthetics of the zipper pull, the pair of flanges can also be positioned opposite each other at the opposite outer ends of the first wing plate in the width direction, with the outer ends of the flanges offset inwards relative to the outer ends of the first wing plates in the width direction. This creates an outward-facing step between the outer ends of the flanges and the outer ends of the first wing plates, thereby reducing the visibility of the flanges from the outside and improving the aesthetics of the zipper pull.

[0004] However, when using injection molding processes with resin materials to manufacture the aforementioned zipper pull with stepped sections, the resin material's flowability in the corresponding mold is poor due to the aforementioned structure. This is especially true when the injection molding process begins from the rear end of the first and second flanges (opposite to the front end where the guide post is located), making it difficult for the resin material to flow forward through the mold shape corresponding to the stepped flange (and vice versa), thus reducing the structural strength of the zipper pull. Therefore, it is necessary to improve the structure of the zipper pull to enhance its structural strength while maintaining its aesthetic appeal. Utility Model Content

[0005] This invention provides a zipper pull that can improve structural strength while maintaining aesthetics.

[0006] The zipper pull of this utility model includes: a first wing plate and a second wing plate, which are arranged opposite each other with a gap between them; a guide post connecting the front ends of the first wing plate and the second wing plate; and a pair of flanges, which are arranged opposite each other in the width direction of the first wing plate and are arranged upright towards the second wing plate. The first wing plate with the pair of flanges forms a step portion facing outward in the width direction at its two opposite outer ends in the width direction and the outer end of the corresponding flange, and the step portion has a rib portion extending along the corresponding flange.

[0007] In the zipper pull of the present invention, the step portion is formed by providing a flange on the corresponding side at a position spaced apart from the outer end of the first wing plate in the width direction.

[0008] In the zipper pull of this utility model embodiment, the convex rib is inclined in the vertical direction from the outer end of the first wing plate to the end of the flange on the corresponding side.

[0009] In the zipper pull of this embodiment of the present invention, the convex rib is inclined from the front end portion toward the guide post toward the middle portion and from the rear end portion away from the guide post toward the middle portion.

[0010] In the zipper pull of this utility model embodiment, the thickness of the middle portion of the convex rib is greater than the thickness of the front end portion of the convex rib and greater than the thickness of the rear end portion of the convex rib, thus forming an arc-shaped profile that protrudes in the thickness direction.

[0011] In the zipper pull of this utility model embodiment, the outer end face of the convex rib is located further inward than the outer end face of the first wing plate in the width direction, or is coplanar with the outer end face of the first wing plate.

[0012] In the zipper pull of this utility model embodiment, the guide post is provided with a through hole, which passes through the guide post and the first wing plate and the second wing plate connected by the guide post.

[0013] Based on the above, in the zipper pull of this invention, a pair of flanges are arranged opposite to each other in the width direction of the first wing plate and stand facing the second wing plate. The first wing plate, with its pair of flanges, forms a step portion facing outwards in the width direction at its two opposite outer ends with the outer ends of the corresponding flanges. The step portion has a rib extending along the corresponding flange. Thus, by offsetting the outer ends of the flanges inwards in the width direction relative to the outer ends of the first wing plate, and forming an outward-facing step portion between the outer ends of the flanges and the outer ends of the first wing plate, the visibility of the flanges from the outside is reduced, thereby improving the aesthetics of the zipper pull. Furthermore, by providing ribs extending along the flanges in the step portion, the step portion can be reinforced along the flanges, thereby improving the structural strength of the zipper pull. Therefore, the zipper pull of this invention can improve structural strength while maintaining aesthetics.

Figures 1 to 7 This invention describes the specific structure of a zipper pull 100 according to one embodiment of the present invention, but the present invention is not limited thereto and can be adjusted according to requirements.

[0047] Please refer to Figures 1 to 5 In this embodiment, the zipper pull 100 includes a first wing plate 110 (e.g., an upper wing plate) and a second wing plate 120 (e.g., a lower wing plate), a guide post 130, and a pair of flanges 140. The first wing plate 110 and the second wing plate 120 are arranged opposite each other with a gap between them. The guide post 130 connects the front ends E1 of the first wing plate 110 and the second wing plate 120. The pair of flanges 140 are arranged opposite each other in the width direction W (corresponding to the left-right direction) of the first wing plate 110 and are upright facing the second wing plate 120. The first wing plate 110 with the pair of flanges 140 has two opposite outer ends 112 in the width direction W, each forming a step portion 150 facing outward in the width direction W with the outer end 142 of the corresponding flange 140. The step portion 150 has a rib portion 160 extending along the corresponding flange 140. The zipper pull 100 is suitable for use on a zipper chain (not shown). The zipper chain to which the zipper pull 100 is applicable can be any of the zipper chains in the prior art, or any of the zipper chains that have been developed in the future. This utility model is not limited to this.

[0048] Specifically, in this embodiment, as Figures 1 to 5As shown, the first wing plate 110 and the second wing plate 120 are each configured as plate-shaped components, and each has a generally arc-shaped front end E1 and a generally rectangular rear end E2. The first wing plate 110 and the second wing plate 120 are spaced apart from each other in the vertical direction (corresponding to the thickness direction T) and are arranged generally parallel (not limited thereto), and are connected to each other at the front end E1 by guide posts 130 extending in the vertical direction (thickness direction T), thus serving as the upper wing plate and the lower wing plate. Although the example described here is the first wing plate 110 as the upper wing plate and the second wing plate 120 as the lower wing plate, it is also possible to describe it as the first wing plate 110 as the lower wing plate and the second wing plate 120 as the upper wing plate. The first wing plate 110 is used to refer to one of the upper wing plate and the lower wing plate having a pair of flanges 140, and is not limited to either the upper wing plate or the lower wing plate. Thus, the zipper pull 100 can be mounted on a zipper chain (not shown) via the first wing plate 110 and the second wing plate 120, and slide by separating a pair of zipper straps and a pair of chain teeth of the zipper chain via the guide post 130. However, in other embodiments (not shown), the first wing plate 110 and the second wing plate 120 may have other shapes (the shapes of the first wing plate 110 and the second wing plate 120 may be different), and the shape and position of the guide post 130 may also be adjusted according to requirements; this utility model is not limited thereto.

[0049] Furthermore, in this embodiment, as Figures 1 to 5 As shown, a pair of flanges 140 are, for example, protruding structures at opposite outer ends 112 of the first wing plate 110 in the width direction W, and protrude from the inner side of the first wing plate 110 toward the opposite second wing plate 120, standing upright on the inner side of the first wing plate 110 (but not contacting the second wing plate 120, leaving a gap). As an example, the pair of flanges 140 extend along the approximate length direction L (corresponding to the front-rear direction) toward the rear end E2 of the first wing plate 110 from the portion on the inner side of the first wing plate 110 corresponding to the rear end side of the guide post 130, forming arc-shaped ribs. In this way, the zipper pull 100 can allow a pair of zipper tapes to pass through the gap between the pair of flanges 140 of the first wing plate 110 and the opposite second wing plate 120, and the pair of flanges 140 restrict the position of the pair of zipper teeth in the width direction W. However, in other embodiments not shown, a pair of flanges 140 may also be arranged opposite each other in the width direction W of the second wing plate 120 and facing the first wing plate 110, and the shape of the pair of flanges 140 may also be adjusted as needed, and this utility model is not limited thereto.

[0050] Therefore, in this embodiment, as Figures 1 to 5As shown, a pair of flanges 140 are disposed opposite to each other at their opposite outer ends 112 in the width direction W of the first wing plate 110, but at least a portion of each flange 140 (e.g., the portion other than the front end portion in the length direction L) is spaced apart from the outer ends 112 in the width direction W of the first wing plate 110. As an example, the step portion 150 is formed by standing the corresponding flange 140 at a position spaced apart from the outer ends 112 in the width direction W of the first wing plate 110. That is, the outer ends 142 of the flanges 140 are not aligned with the outer ends 112 of the first wing plate 110, but are offset inward in the width direction W relative to the outer ends 112 of the first wing plate 110. Thus, a stepped space extending in the approximate length direction L and recessed inward in the vertical direction Z is formed between the outer ends 142 of the flanges 140 and the outer ends 112 of the first wing plate 110, and this space serves as the step portion 150 facing outward. However, the specific structure of the step section 150 can be adjusted according to requirements, and this utility model is not limited thereto.

[0051] Furthermore, in this embodiment, such as Figures 1 to 5 As shown, a rib 160 is formed along the corresponding side of the flange 140 between the outer end 142 of the flange 140 and the outer end 112 of the first wing 110 (in the step portion 150). As an example, the outer end face 164 of the rib 160 is located more inwardly than the outer end face 114 of the first wing 110 in the width direction W, or is coplanar with the outer end face 114 of the first wing 110. That is, the outer end face 164 of the rib 160 can connect with and be aligned with the outer end face 114 of the first wing 110, or it can be offset inwardly in the width direction W relative to the outer end face 114 of the first wing 110 (here, the rib 160 is shown as an inclined outer end face 164 that is inwardly inclined relative to the outer end face 114 of the first wing 110, such as...). Figure 5 (As shown). Therefore, even if a rib 160 is provided in the step portion 150 for reinforcement, the rib 160 will not protrude beyond the outer side of the step portion 150 and the first wing plate 110. Further configuration of the rib 160 can be as described later, and the specific structure can be adjusted according to requirements. This utility model is not limited thereto.

[0052] With the above configuration, in the zipper pull 100, a pair of flanges 140 are positioned opposite each other in the width direction W of the first wing plate 110 and facing the second wing plate 120. The two opposite outer ends 112 of the first wing plate 110 with the pair of flanges 140 in the width direction W each form a step portion 150 facing outwards in the width direction W with the outer end 142 of the corresponding flange 140. The step portion 150 has a protruding rib 160 extending along the corresponding flange 140. Thus, by offsetting the outer end 142 of the flange 140 inwards in the width direction W relative to the outer end 112 of the first wing plate 110, and forming the outward-facing step portion 150 between the outer end 142 of the flange 140 and the outer end 112 of the first wing plate 110, the visibility of the flanges 140 from the outside can be reduced, thereby improving the aesthetics of the zipper pull 100. Furthermore, by providing a rib 160 extending along the flange 140 in the step portion 150, the step portion 150 can be reinforced along the flange 140, thereby improving the structural strength of the zipper pull 100. Accordingly, the zipper pull 100 can improve its structural strength while maintaining its aesthetic appeal.

[0053] Furthermore, in this embodiment, as Figures 5 to 7 As shown, the rib 160 slopes in the vertical direction (corresponding to the thickness direction T) from the outer end of the first wing plate 110 (the side corresponding to the outer end 112) towards the end of the flange 140 on the corresponding side. That is, in a cross-sectional view, the thickness of the rib 160 increases from the outer end 162 towards the inner end 166, and the width of the rib 160 decreases from the first wing plate 110 side towards the second wing plate 120 side. Thus, the rib 160 is formed as a tapered structure, etc., that slopes in the width direction W from the outer end 162 side towards the inner end 166 side and in the thickness direction T from the first wing plate 110 side towards the second wing plate 120 side, and the rib 160 does not completely fill the entire step portion 150. Therefore, the zipper pull 100 can improve structural strength while maintaining aesthetics. However, this invention is not limited to this and can be adjusted according to requirements.

[0054] Furthermore, in this embodiment, as Figure 4 As shown, the convex rib 160 slopes from the front end portion 167 towards the middle portion 168 and from the rear end portion 169 away from the guide post 130 towards the middle portion 168. As an example, the thickness t1 of the middle portion 168 of the convex rib 160 is greater than the thickness t2 of the front end portion 167 and greater than the thickness t3 of the rear end portion 169, forming a tapered front end portion 167 and rear end portion 169 in the thickness direction T, thus forming an arc-shaped profile that protrudes in the thickness direction T (e.g., ...). Figure 4 (As shown). Similarly, as Figures 5 to 7As shown, the width w1 of the middle portion 168 of the convex rib 160 (as shown) Figure 6 (As shown) The width w2 of the front end portion 167 of the convex rib 160 is greater than the width w2 of the convex rib 160. Figure 5 (as shown) and greater than the width w3 of the rear end portion 169 of the convex rib 160 (as shown) Figure 7 As shown), a reduced front end portion 167 and a reduced rear end portion 169 are formed in the width direction W. Thus, the front end portion 167 and the rear end portion 169 of the rib 160 in the length direction L (corresponding to the front-to-back direction) have reduced thickness and width relative to the middle portion 168. The rib 160 does not completely fill the entire step portion 150. Furthermore, the reduced front end portion 167 and the reduced rear end portion 169 of the rib 160 facilitate the flow of resin material through the mold corresponding to the structure during the injection molding process. However, this invention is not limited thereto and can be adjusted according to requirements.

[0055] Therefore, in this embodiment, as Figures 1 to 3 As shown, the guide post 130 is provided with a through hole 132, which penetrates the guide post 130 and the first wing plate 110 and the second wing plate 120 connected by the guide post 130. That is, the through hole 132 extends in a generally vertical direction (equivalent to the thickness direction T), and the first end 132a of the through hole 132 penetrates the surface of the first wing plate 110 (e.g., ...). Figure 1 (as shown) and the second end 132b penetrates the surface of the second wing 120 (as shown) Figure 2 (As shown). Thus, the through hole 132 connects the first wing plate 110 and the second wing plate 120 on both the upper and lower sides via the guide post 130, and can serve as a through hole for purposes such as appearance design, weight reduction, and connection of the zipper pull 100. Furthermore, even with such a complex structure as the guide post 130 having a through hole 132, since the zipper pull 100 has a step portion 150 and a raised rib portion 160 as described above, the resin material can easily flow through the mold corresponding to the structure during the injection molding process. However, this utility model is not limited to this, and it can be adjusted according to needs.

[0056] In summary, in the zipper pull of this invention, a pair of flanges are arranged opposite to each other in the width direction of the first wing plate and stand facing the second wing plate. The first wing plate, with its pair of flanges, forms a step portion facing outwards in the width direction at its two opposite outer ends with the outer ends of the corresponding flanges. The step portion has a rib extending along the corresponding flange. Thus, by offsetting the outer ends of the flanges inwards in the width direction relative to the outer ends of the first wing plate, and forming an outward-facing step portion between the outer ends of the flanges and the outer ends of the first wing plate, the visibility of the flanges from the outside is reduced, thereby improving the aesthetics of the zipper pull. Furthermore, by providing ribs extending along the flanges in the step portion, the step portion can be reinforced along the flanges, thereby improving the structural strength of the zipper pull. Preferably, the ribs are inclined vertically from the outer end of the first wing plate towards the end of the corresponding flange, thereby improving structural strength while maintaining aesthetics. Accordingly, the zipper pull of this utility model can improve structural strength while maintaining aesthetics.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
