Abstract
Description
Technical Field
[0001] This utility model relates to a technology in the field of zippers, and more particularly to a zipper tab puller. Background Technology
[0002] A typical zipper usually consists of a zipper chain made up of a pair of zipper tapes and element columns mounted on the tapes, and a zipper slider mounted on the zipper chain that opens or closes the element columns by sliding. The zipper slider opens or closes the element columns by sliding along the zipper chain. Furthermore, a zipper tab can be attached to the zipper slider to further drive the slider along the zipper chain.
[0003] In existing technologies, zipper pulls are typically stacked in pairs while undergoing surface treatments such as spray coating and coloring. However, the flat surfaces of the zipper pulls rub against each other during stacking, leading to uneven coating. Therefore, it is envisioned that ribs be added around the outer perimeter of the zipper pulls to reduce the contact area between them during stacking, thereby improving the uneven coating phenomenon.
[0004] However, even after repeated light-colored spraying of the overlapping pairs of zipper pull tabs, uneven coating still occurs. In other words, the existing structure with ribs on the zipper pull tabs is insufficient to comprehensively improve the uneven coating. Therefore, it is necessary to improve the structure of the zipper pull tabs, hoping that the uneven coating can be improved during the overlapping arrangement and surface treatment processes such as spraying. Utility Model Content
[0005] This utility model provides a zipper pull tab that can improve the spraying effect when overlapping while also taking into account structural strength.
[0006] The zipper pull tab provided by this utility model includes: a pull tab body, including a grip portion extending in the length direction and a mounting ring portion located at the end of the grip portion; and a rib located at the outer periphery of the grip portion and protruding in the thickness direction from a first surface and a second surface of the grip portion that are opposite to each other, wherein the rib has a first recess corresponding to the first surface and a second recess corresponding to the second surface, and the first recess starting point of the first recess and the second recess starting point of the second recess are offset in the length direction of the grip portion.
[0007] In an embodiment of this utility model, the deepest point of the first recess of the first recess and the deepest point of the second recess of the second recess are offset in the length direction of the gripping portion.
[0008] In an embodiment of the present invention, the first recess and the second recess are located in the length direction closer to the front half of the mounting ring portion than the middle portion of the grip portion.
[0009] In an embodiment of this utility model, the first recess is provided in pairs on the left and right sides of the convex rib in the width direction, and the second recess is provided in pairs on the left and right sides of the convex rib in the width direction.
[0010] Based on the above, in the zipper pull tab of this invention, the ribs located on the outer periphery and protruding from the first and second surfaces have a first recess corresponding to the first surface and a second recess corresponding to the second surface, and the first recess starting point of the first recess and the second recess starting point of the second recess are offset in the length direction. Thus, when the zipper pull tabs are stacked in pairs, regardless of which side of the zipper pull tab is in contact with the first or second surface, the zipper pull tabs can not only reduce the contact area between each other through the ribs, but also further reduce the contact area through the first and second recesses, thereby improving the uneven coating situation. Furthermore, the offset of the first and second recesses in the length direction can prevent the thinning of the ribs from concentrating, thus avoiding excessive damage to the structural strength. Therefore, the zipper pull tab of this invention can improve the coating effect when stacked while maintaining structural strength.

The following will use... Figures 1 to 6 This invention describes the specific structure of the zipper pull tab 100 in this embodiment and its operation when they are arranged in pairs and overlapping. However, the above description is only an example and is not intended to limit the invention. It can be adjusted according to requirements.
[0038] Please refer to Figures 1 to 3 In this embodiment, the zipper pull tab 100 includes a pull tab body 110 and a rib 120. The pull tab body 110 includes a grip portion 112 extending in the length direction L (corresponding to the front-to-back direction) and a mounting ring portion 114 located at the end of the grip portion 112 (e.g., the front end). The rib 120 is located at the outer periphery of the grip portion 112 and extends in the thickness direction T from the opposing first surfaces 112S1 of the grip portion 112 (e.g., the front surface). Figure 1 (as shown) and the second surface 112S2 (as shown) Figure 2 (As shown) protrudes. The rib 120 has a first recess 122 corresponding to the first surface 112S1 and a second recess 124 corresponding to the second surface 112S2 (as shown). Figure 3 As shown), the first recess starting point 122A (corresponding to the front end) of the first recess 122 and the second recess starting point 124A (corresponding to the front end) of the second recess 124 are offset in the length direction L of the grip portion 112.
[0039] Specifically, in this embodiment, as Figures 1 to 3 As shown, the gripping portion 112 of the pull tab body 110 is configured as a flat plate structure that is long in the length direction L and thin in the thickness direction T, and the mounting ring portion 114 is configured as a flat ring structure located at the end of the gripping portion 112. The zipper pull tab 100 is adapted to be mounted on the pull tab mounting post 52 of the zipper pull head 50 via the mounting ring portion 114 of the pull tab body 110 (e.g., Figure 1 and Figure 2(As shown in the diagram). The zipper pull tab 100 mounted on the zipper pull 50 can be flipped relative to the zipper pull 50 via the mounting ring 114. For example, as... Figure 1 As shown, the zipper pull 100 is positioned inside the zipper pull 50 (overlapping with the zipper pull 50) with the first surface 112S1 of the grip 112 facing the surface side, or it can be positioned outside the zipper pull 50 with the second surface 112S2 of the grip 112 facing the surface side (for example, on the outside of the zipper pull 50). Figure 1 Based on this, it is flipped upwards from the zipper pull 50 and moves away from the zipper pull 50. In this way, by operating the zipper pull tab 100, the zipper pull 50 can be driven to slide on the zipper chain (not shown). However, in other embodiments not shown, this invention is not limited thereto and can be adjusted as needed.
[0040] Furthermore, in this embodiment, as Figures 1 to 3 As shown, the rib 120 is configured as a protruding rib structure that increases the thickness of the grip portion 112 at its outer periphery. For example, the rib 120 surrounds opposite sides of the grip portion 112 in the width direction W (corresponding to the left-right direction) and the end of the grip portion 112 opposite to the mounting ring portion 114 (for example, the rear end). That is, the rib 120 surrounds the outer periphery of three adjacent sides of the grip portion 112. Furthermore, the rib 120 protruding from the first surface 112S1 and the second surface 112S2 of the grip portion 112 connects to the mounting ring portion 114, and is coplanar with the mounting ring portion 114 on the first surface 112S1 side (corresponding to the front side) and the second surface 112S2 side (corresponding to the back side). That is, the coplanar rib 120 and the mounting ring portion 114 form a recessed area at the central portion of the first surface 112S1 and the second surface 112S2 of the grip portion 112. Thus, while maintaining the aesthetics of the zipper pull tab 100, a rib 120 is formed to reduce the contact area of the grip portion 112. However, in other embodiments not shown, a separate pair of ribs 120 may be provided only on opposite sides in the width direction W of the grip portion 112, and the ribs 120 may protrude relative to the grip portion 112 and the mounting ring portion 114. This invention is not limited thereto and can be adjusted according to requirements.
[0041] Furthermore, in this embodiment, such as Figures 1 to 3As shown, the rib 120, located on the outer periphery and protruding from the first surface 112S1 and the second surface 112S2, has a first recess 122 corresponding to the first surface 112S1 and a second recess 124 corresponding to the second surface 112S2. The first recess starting point 122A (corresponding to the front end) of the first recess 122 and the second recess starting point 124A (corresponding to the front end) of the second recess 124 are offset in the length direction L. That is, the portion of the rib 120 corresponding to the first surface 112S1 (front side) has a recessed first recess 122, and the portion of the rib 120 corresponding to the second surface 112S2 (back side) has a recessed second recess 124. At least a portion of the first recess 122 and the second recess 124 do not overlap each other in the length direction L. Thus, when the zipper pull tabs 100 are arranged in pairs and overlapped (e.g., ...), ... Figures 4 to 6 When the zipper pull tab 100 is simultaneously subjected to surface treatments such as spray painting and coloring (as shown), regardless of whether the first surface 112S1 or the second surface 112S2 of the zipper pull tab 100 is in contact with each other, the zipper pull tab 100 can not only reduce the contact area between each other through the ribs 120, but also further reduce the contact area through the arrangement of the first recess 122 and the second recess 124, thereby improving the unevenness of the spraying. In addition, the first recess 122 and the second recess 124 are staggered in the length direction L, which can prevent the thickness of the ribs 120 from concentrating at the thinnest points, and avoid excessive damage to the structural strength. Accordingly, the zipper pull tab 100 can improve the spraying effect when overlapped while taking into account the structural strength.
[0042] Furthermore, in this embodiment, as Figures 1 to 3 As shown, when the zipper pull tabs 100 are arranged in pairs and overlapped, the zipper pull tabs 100 can be mounted on the zipper pull head 50 and sprayed together (e.g., Figure 4 (As shown), the zipper pull 100 can also be sprayed only on zippers that have not yet been installed (such as...). Figure 5 and Figure 6 (As shown). Furthermore, when the zipper pull tabs 100 are arranged in pairs and overlapped, the zipper pull tabs 100 can be arranged in pairs with the second surface 112S2 of the upper zipper pull tab 100 contacting the first surface 112S1 of the lower zipper pull tab 100 (as shown). Figure 4 As shown), the zipper pull tab 100 on the upper side can be arranged in pairs with its first surface 112S1 in contact with the first surface 112S1 of the zipper pull tab 100 on the lower side, overlapping each other (e.g.). Figure 5 (As shown), or the upper zipper pull tab 100's second surface 112S2 contacts the lower zipper pull tab 100's second surface 112S2, and they are arranged in pairs overlapping (e.g.) Figure 6(As shown). At this time, since the ribs 120 of the zipper pull tab 100 are provided with a first recess 122 and a second recess 124 respectively in the portion corresponding to the first surface 112S1 and the portion corresponding to the second surface 112S2, regardless of which side of the zipper pull tab 100 is in contact with the first surface 112S1 or the second surface 112S2, the zipper pull tab 100 can further reduce the contact area through at least one of the first recesses 122 and the second recesses 124, thereby improving the uneven coating situation. Therefore, the zipper pull tab 100 can be adjusted in overlapping manner to suit various different coating methods, resulting in a good coating effect.
[0043] Therefore, in this embodiment, as Figures 1 to 3 As shown, the deepest point 122B of the first recess 122 and the deepest point 124B of the second recess 124 are offset in the length direction L of the grip portion 112. That is, when the first recess 122 and the second recess 124 are formed as arc-shaped recessed structures, the deepest point 122B of the first recess 122 is further back in the length direction L (opposite to the side of the mounting ring portion 114) and more recessed than the starting point 122A of the first recess, and the deepest point 124B of the second recess 124 is further back in the length direction L and more recessed than the starting point 124A of the second recess, and the deepest point 122B of the first recess 122 is offset from the deepest point 124B of the second recess 124 because it is further back in the length direction L. Thus, not only are the first recess starting point 122A of the first recess 122 and the second recess starting point 124A of the second recess 124 offset in the length direction L of the gripping portion 112, but the deepest point 122B of the first recess 122 and the deepest point 124B of the second recess 124 are also offset in the length direction L of the gripping portion 112. This avoids the concentration of the thinner areas of the rib 120, thereby further preventing excessive damage to the structural strength. However, although the deepest point 122B of the first recess is shown here as the central part of the first recess 122 and the deepest point 124B of the second recess is shown as the central part of the second recess 124, the dimensions (e.g., length in the length direction L) and shapes of the first recess 122 and the second recess 124 can be the same or different, and the first recess 122 and the second recess 124 can partially overlap or be completely offset in the length direction L. This utility model is not limited to these, and can be adjusted according to requirements.
[0044] Additionally, in this embodiment, as Figures 1 to 3As shown, the first recess 122 and the second recess 124 are located in the longitudinal direction L of the grip portion 112, closer to the front half of the mounting ring portion 114 than the middle portion. For example, the first recess 122 is located in the front half of the first surface 112S1 side (front side) of the rib 120, and the second recess 124 is located in the front half of the second surface 112S2 side (back side) of the rib 120. The second recess 124 is closer to the mounting ring portion 114 than the first recess 122, but the opposite is also possible, i.e., the first recess 122 is closer to the mounting ring portion 114 than the second recess 124. This further avoids excessive damage to the structural strength. Furthermore, as an example, such as... Figure 1 As shown, the first recesses 122 are arranged in pairs on the left and right sides of the protruding rib 120 in the width direction W, and as... Figure 2 As shown, the second recesses 124 are arranged in pairs on the left and right sides of the convex rib 120 in the width direction W. However, in other embodiments not shown, only one first recess 122 and one second recess 124 may be provided on the convex rib 120, or more first recesses 122 and more second recesses 124 may be provided. The dimensions (e.g., length in the length direction L) of a pair of first recesses 122 may be the same or different, and their positions in the length direction L may be the same or staggered. The dimensions (e.g., length in the length direction L) of a pair of second recesses 124 may be the same or different, and their positions in the length direction L may be the same or staggered. The number and relative position of the first recesses 122 and second recesses 124 can be adjusted according to requirements, and this utility model is not limited thereto.
[0045] In summary, in the zipper pull tab of this invention, the ribs located on the outer periphery and protruding from the first and second surfaces have a first recess corresponding to the first surface and a second recess corresponding to the second surface, and the first recess starting point of the first recess and the second recess starting point of the second recess are offset in the length direction. Thus, when the zipper pull tabs are arranged in pairs and overlapped, regardless of which side of the zipper pull tab is in contact with the first or second surface, the zipper pull tabs can not only reduce the contact area between each other through the ribs, but also further reduce the contact area through the arrangement of the first and second recesses, thereby improving the uneven coating situation. Furthermore, the offset of the first and second recesses in the length direction can prevent the thinning of the ribs from concentrating, thus avoiding excessive damage to the structural strength. Preferably, the deepest point of the first recess of the first recess and the deepest point of the second recess of the second recess are offset along the length of the grip, and the first and second recesses are located closer to the front half of the mounting ring along the length, thereby further avoiding excessive damage to the structural strength. Accordingly, the zipper pull tab of this invention can improve the spraying effect when overlapping while maintaining structural strength.
[0046] 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.
