Figure 6 yes Figure 5 The diagram shows a side view of the zipper pull assembly. The following will use... Figures 1 to 3 This invention describes the specific structure of the zipper pull 100 in an embodiment of the present invention, and uses... Figures 4 to 6The present invention describes the specific structure of the zipper pull assembly 200 and the zipper 50 in the embodiments of the present invention. However, the above content is only an example and the present invention is not limited thereto. It can be adjusted according to the needs.

[0063] Please refer to Figures 1 to 3 In this embodiment, the zipper pull 100 includes a pull body 110, a single-layer plate-like portion 120, and a rib portion 130. The pull body 110 is adapted to be mounted on the zipper chain 60 (e.g., Figure 4 (As shown) and slides relative to the zipper chain 60 in the length direction L (corresponding to the front-to-back direction) of the zipper chain 60. The single-layer plate-shaped portion 120 extends forward from the front end side Fr of the upper end portion 112 of the zipper head body 110, and is located on the first side S1 (e.g., the outer side) in the width direction W (corresponding to the left-to-right direction) of the zipper head body 110. Figure 1 and Figure 2 (Seen as the left side) Offset setting. A rib 130 is formed on the second side S2 (e.g., the inner side) of the front end 122 of the plate-like portion 120, corresponding to the width direction W. Figure 1 and Figure 2 On the side 124 (shown as the right side), the protruding rib 130 has a mating surface 132 facing the second side S2 in the width direction W, which is orthogonal to the sliding direction (i.e., the length direction L) of the slider body 110.

[0064] Specifically, in this embodiment, as Figures 1 to 3 As shown, the zipper pull body 110 includes an upper wing plate 111 and a lower wing plate 113 that are spaced apart from each other and arranged opposite to each other in the vertical direction (equivalent to the thickness direction T), a separating post 115 provided at the front end 114 on the front end side Fr and connecting the upper wing plate 111 and the lower wing plate 113, and a pair of flange portions 117 provided at least on the left and right sides of the upper wing plate 111, wherein the zipper pull body 110 is adapted to form a zipper tape 62 and a chain of teeth 64 for the zipper chain 60 between the upper wing plate 111 and the lower wing plate 113 (e.g., ...). Figure 4 As shown, the zipper pull body 110 is positioned by a flange 117 that limits the pair of chain teeth 64 through the space, and the separation post 115 on the front end Fr separates the pair of chain teeth 64 from the pair of zipper straps 62 during sliding (the rear end Rr is the open side). Thus, the zipper pull body 110 can be mounted on the zipper chain 60 and slide relative to the zipper chain 60 in the length direction L. Furthermore, as an example, a single-layer plate-like portion 120 extends forward from the front end Fr of the upper surface of the upper wing plate 111, i.e., the upper end 112 of the zipper pull body 110. However, the specific structure of the zipper pull body 110 can be adjusted according to requirements, and this invention is not limited thereto.

[0065] Furthermore, in this embodiment, as Figures 1 to 3As shown, the single-layer plate-shaped portion 120 extends upward and forward relative to the upper surface of the upper end portion 112, i.e., the upper wing plate 111, of the slider body 110. Furthermore, the plate-shaped portion 120 is offset towards the first side S1 (e.g., the outer side) relative to the centerline C in the length direction L of the slider body 110 in the width direction W. Here, the entire plate-shaped portion 120 is positioned towards the first side S1 relative to the centerline C, but it is also possible that only a portion of the rear end 123 of the plate-shaped portion 120 connected to the slider body 110 is located on the second side S2 (e.g., the inner side). As an example, the thickness T1 of the plate-shaped portion 120 in the vertical direction (corresponding to the thickness direction T) is greater than or equal to the thickness T2 of the slider body 110 (e.g., as shown). Figure 3 As shown), and the width W1 of the plate-shaped portion 120 in the width direction W is smaller than the width W2 of the slider body 110 (as shown). Figure 2 (As shown). Thus, the single-layer plate-shaped portion 120 constitutes a single plate-shaped structure relative to the slider body 110, rather than being composed of multiple stacked structures, and the plate-shaped portion 120 protrudes forward relative to the slider body 110 and is offset towards the first side S1 in the width direction W. However, the specific structure of the single-layer plate-shaped portion 120 can be adjusted according to requirements, and this utility model is not limited thereto.

[0066] Furthermore, in this embodiment, such as Figures 1 to 3 As shown, the rib portion 130 protrudes from the side surface 124 corresponding to the second side S2 (e.g., the inner side) of the front end 122 of the plate-like portion 120 toward the second side S2, and is configured as a rib structure extending along the edge of the front end 122 of the plate-like portion 120 (e.g., Figure 3 (As shown). Furthermore, the rib 130 has a mating surface 132 facing the second side S2. The mating surface 132 is, for example, a flat surface capable of mating with the mating surface 132 of the opposing rib 130 (as described later), and is substantially parallel to the side surface 124 of the plate-like portion 120 (as shown). Figure 1 and Figure 2 As shown). Thus, the dimension D1 of the rib 130 in the length direction L (i.e., the dimension of the mating surface 132) is greater than the dimension D2 of the rib 130 in the width direction W (as shown). Figure 2 As shown, this improves the fitting effect of the mating surface 132. Furthermore, the protruding rib 130 is formed on the side 124 of the plate-like portion 120 corresponding to the second side S2, which can hide the mating surface 132 within the plate-like portion 120 and provide a fitting effect in the width direction W. However, the specific structure of the protruding rib 130 can be adjusted according to requirements, and this invention is not limited thereto.

[0067] With the above settings, in this embodiment, as follows: Figures 1 to 3As shown, in the zipper pull 100, the front end side Fr of the upper end 112 of the pull body 110 is provided with a single-layer plate-like portion 120 extending forward and offset in the width direction W from a first side S1 (e.g., the outer side). A protruding rib 130 is formed on the side 124 of the front end 122 of the plate-like portion 120 corresponding to a second side S2 (e.g., the inner side), and the protruding rib 130 has a mating surface 132 facing the second side S2. Thus, when the zipper pull 100 is mounted on the zipper chain 60, as... Figure 4 As shown, the zipper pull 100 can be twisted along the length direction L of the zipper chain 60 (e.g., by means of twisting). Figure 4 (As shown by the arrow) Positioning is achieved by the engagement of the convex rib 130 with the opposing convex rib 130 in the width direction W (e.g., it cannot be separated in the length direction L when unlocked), and the engagement of the convex rib 130 can be released in the width direction W by twisting the zipper chain 60 along the length direction L (e.g., loosening the twisted zipper chain 60) or by twisting in the opposite direction. The twisting along the length direction L can be achieved by sliding the zipper pull 100 in the length direction L while slightly rotating it in the width direction W, without the need for complex unlocking methods such as bending the zipper chain 60 up and down to rotate the zipper pull 100 significantly in opposite directions. Accordingly, the zipper pull 100 can improve the smoothness of operation when unlocking through a simple operation method.

[0068] Furthermore, in this embodiment, as Figures 4 to 6 As shown, the zipper pull assembly 200 includes a pair of zipper pulls 100. The pair of zipper pulls 100 are arranged in pairs with their front ends 114, which are provided with plate-like portions 120, facing each other. When the front ends 114 of the pair of zipper pulls 100 are abutted together, the protruding ribs 130 of each zipper pull 100 engage with the opposing protruding ribs 130. The zipper 50 includes a zipper chain 60 and a pair of zipper pulls 100 (i.e., the zipper pull assembly 200). The zipper chain 60 extends in the length direction L. A pair of zipper pulls 100 are mounted on the zipper chain 60 with their front ends 114, which are provided with plate-shaped portions 120, facing each other. When the front ends 114 of the pair of zipper pulls 100 slide on the zipper chain 60 and abut each other, the protruding ribs 130 of each zipper pull 100 engage with the opposing protruding ribs 130. In other words, the main difference between the zipper pull assembly 200 and the zipper 50 lies in the arrangement of the zipper chain 60. The zipper chain 60 includes a pair of left and right zipper tapes 62 and a pair of left and right chain teeth 64 (e.g., [missing information]) provided on the left and right zipper tapes 62. Figure 4(As shown). This example uses a coiled chain tooth array, but the specific structure of the zipper pull assembly 200 and the zipper 50 can be adjusted according to requirements, and this utility model is not limited thereto.

[0069] With the above settings, in this embodiment, as follows: Figures 4 to 6 As shown, in the zipper pull assembly 200 and the zipper 50, when a pair of zipper pulls 100 are arranged in pairs on the zipper chain 60 with their front ends 114 facing each other, the zipper pulls 100 having the same structure are arranged in opposite directions along the length L of the zipper chain 60. The plate-shaped portions 120, which are offset towards the first side S1 (e.g., the outer side) in the width direction W, are arranged opposite each other in the width direction W, and the protruding ribs 130 provided on the side 124 of the plate-shaped portions 120 facing the second side S2 (e.g., the inner side) abut against each other with their mating surfaces 132. Thus, the zipper pull assembly 200 and the zipper 50 equipped with the zipper pulls 100 also possess the aforementioned effect, that is, the zipper pulls 100 can be rotated along the length L of the zipper chain 60 (e.g., by twisting the zipper chain 60 along the length direction L). Figure 4 (As shown by the arrow) Positioning is achieved by the engagement of the convex rib 130 with the opposing convex rib 130 in the width direction W (e.g., it cannot be separated in the length direction L when unlocked), and the engagement of the convex rib 130 can be released in the width direction W by twisting the zipper chain 60 along the length direction L (e.g., loosening the twisted zipper chain 60) or by twisting in the opposite direction. The twisting along the length direction L can be achieved by sliding the zipper pull 100 in the length direction L while slightly flipping it in the width direction W, without the need for complex unlocking methods such as bending the zipper chain 60 up and down to rotate the zipper pull 100 significantly in opposite directions. Accordingly, the zipper pull assembly 200 and the zipper 50 can improve the smoothness of operation when unlocking through a simple operation method.

[0070] Please refer to this again. Figures 1 to 3 In this embodiment, the plate-shaped portion 120 is provided with a through hole 126, which penetrates the plate-shaped portion 120 in the width direction W. A rib 130 is formed on the side surface 124 of the plate-shaped portion 120 along the outer periphery of the through hole 126 at the front end 122 of the plate-shaped portion 120. As an example, the front end 122 of the plate-shaped portion 120 is configured as a plate-shaped structure with a semi-circular outline, and the through hole 126 is a circular hole, thus forming a semi-circular ring at the front end 122, and the rib 130 is formed along the semi-circular edge of the front end 122 at the front side of the through hole 126. Thus, when a pair of zipper pulls 100 are arranged in pairs on the zipper chain 60 with their front ends 114 facing each other, such as... Figure 4As shown, the protruding rib portions 130 of the pair of zipper pulls 100 are engaged with each other through the engagement surfaces 132, so that the through holes 126 are aligned with each other, and a locking member such as a padlock (Nanjing lock) can pass through to lock the pair of zipper pulls 100. The arrangement of the protruding rib portions 130 does not affect the arrangement of the through holes 126, and the alignment of the through holes 126 can be further limited by the protruding rib portions 130, i.e., the alignment of the through holes 126 is completed while the protruding rib portions 130 are engaged with each other. Thus, the zipper pull 100, the zipper pull set 200, and the zipper 50 have better operability. However, the relative positions of the protruding rib portions 130 and the through holes 126, the specific structure of the through holes 126, and whether the through holes 126 are arranged or not can be adjusted according to requirements, and the utility model is not limited in this regard.

[0071] Furthermore, in the present embodiment, as shown in Figures 1 to 3 , the lower side of the front end (here, the front end 134 of the protruding rib portion 130 is taken as an example) of at least one of the plate-shaped portion 120 and the protruding rib portion 130 is provided with a hook portion 136, and the surface of the upper end portion 112 of the pull body 110 is provided with a recessed portion 118. Here, the hook portion 136 is arranged along the width direction W at the front end 134 of the protruding rib portion 130, and forms a transverse hook-shaped structure from the upper side to the lower side and from the front end side Fr to the rear end side Rr (as shown in Figure 1 and Figure 3 ). The recessed portion 118 is arranged along the width direction W at the upper end portion 112 of the pull body 110, and forms a transverse groove-shaped structure from the upper side to the lower side and from the rear end side Rr to the front end side Fr (as shown in Figure 1 and Figure 3 ). Moreover, the recessed portion 118 is arranged on the second side S2 relative to the hook portion 136 in the width direction W (as shown in Figure 2 ). In this way, when the pair of zipper pulls 100 are arranged in pairs on the zipper chain 60 with the front end portions 114 facing each other, as shown in Figure 4 , the protruding rib portions 130 of the pair of zipper pulls 100 are engaged with each other through the engagement surfaces 132, so that the hook portion 136 and the opposite recessed portion 118 are engaged, and the pair of zipper pulls 100 can be further locked. The arrangement of the protruding rib portions 130 does not affect the arrangement of the hook portion 136 and the recessed portion 118. Thus, the zipper pull 100, the zipper pull set 200, and the zipper 50 have better operability. However, the hook portion 136 can be further arranged along the width direction W to the front end 122 of the plate-shaped portion 120 on the first side S1 (for example, the outer side) relative to the protruding rib portion 130, and the recessed portion 118 can be further arranged along the width direction W to the first side S1. The relative positions of the hook portion 136 and the recessed portion 118, the specific structure, and whether the hook portion 136 and the recessed portion 118 are arranged or not can be adjusted according to requirements, and the utility model is not limited in this regard.

[0072] In addition, in the present embodiment, as shown inFigures 1 to 3 As shown, the extending direction D of the plate-shaped portion 120 is inclined forward and towards the first side S1 (e.g., outward) relative to the center line C in the length direction L of the zipper head body 110. That is, the single-layer plate-shaped portion 120 extends forward from the front end side Fr of the upper end 112 of the zipper head body 110 and is inclined towards the first side S1 relative to the center line C. Furthermore, the front end 122 of the plate-shaped portion 120 extends towards the first side S1 relative to the rear end 123, that is, the plate-shaped portion 120 gradually extends towards the first side S1 from the rear end 123 to the front end 122. Furthermore, the protruding rib 130 provided on the side 124 of the front end 122 of the plate-shaped portion 120 also gradually extends towards the first side S1 from the rear end 135 to the front end 134 along with the plate-shaped portion 120. Thus, when a pair of zipper pulls 100 are provided on the zipper chain 60 with their front ends 114 facing each other, as Figure 4 As shown, the convex ribs 130 of a pair of zipper pulls 100 are offset from the opposing convex ribs 130 in the width direction W by the inclined arrangement of the plate-shaped portion 120. This allows the zipper pulls 100 to more easily engage and disengage in the width direction W via the mating surface 132 through the twisting of the zipper chain 60 (i.e., without requiring significant twisting). Therefore, the zipper pulls 100, the zipper pull assembly 200, and the zipper 50 have better operability. However, the specific structure of the plate-shaped portion 120 (whether it is inclined or not, etc.) can be adjusted according to requirements, and this invention is not limited thereto.

[0073] Therefore, in this embodiment, as Figures 1 to 3 As shown, the front end 134 of the convex rib 130 has a chamfer 134a on its side edge corresponding to the second side S2 (e.g., the inner side) in the width direction W, and the chamfer 134a of the convex rib 130 is located on the first side S1 (e.g., the outer side) in the width direction W relative to the center line C. Furthermore, the rear end 135 of the convex rib 130 has a chamfer 135a on its side edge corresponding to the second side S2 in the width direction W. In other words, the convex rib 130 is configured as a flat convex rib structure having a mating surface 132 facing the second side S2 and chamfers on its side edges in the front-rear direction (i.e., the length direction L), with the mating surface 132 located between the front chamfer 134a and the rear chamfer 135a. Preferably, since the convex rib 130 gradually extends obliquely towards the first side S1 from back to front, the front chamfer 134a is closer to the first side S1 relative to the center line C. Thus, when a pair of zippers are mounted on the zipper chain 60 with their front ends 114 facing each other, such as... Figure 4As shown, the protruding rib portions 130 of the pair of the puller 100 are staggered in the width direction W with the pair of the protruding rib portions 130 arranged obliquely with the plate-shaped portion 120, and in particular, the front ends 134 of the protruding rib portions 130 are provided with the chamfer 134a on the first side S1, so that the front ends 134 of the protruding rib portions 130 of the pair can be staggered without colliding with each other, and the fitting can be easily and smoothly performed through the guidance of the chamfer 134a on the front side, and the disengagement of the fitting can be easily and smoothly performed through the guidance of the chamfer 135a on the rear side (i.e., without being twisted greatly). Thus, the puller 100, the puller group 200, and the zipper 50 have better operability. However, the specific structure of the protruding rib portions 130 (whether the chamfers 134a and 135a are provided or not, etc.) can be adjusted according to requirements, and the utility model is not limited in this regard.

[0074] In addition, in the present embodiment, as shown, Figure 1 The upper end portion 112 of the puller body 110 is provided with a protruding pull tab mounting portion 119, and the plate-shaped portion 120 extends forward from the upper end portion 112 of the puller body 110 and the front end portion 119a of the pull tab mounting portion 119. Among them, the pull tab mounting portion 119 is arranged at the position of the upper end portion 112 of the puller body 110, i.e., the upper surface of the upper wing plate 111, which is approximately the center (corresponding to the center line C) in the width direction W, and extends in the length direction L. The front end portion 119a of the pull tab mounting portion 119 is arranged vertically on the upper end portion 112 of the puller body 110 to form a closed end, and the rear end portion 119b is spaced apart from the upper end portion 112 to form an open end, so that the pull tab not shown can be mounted on the pull tab mounting portion 119 through the gap of the rear end portion 119b as the open end (not limited in this regard). In addition, since the front end portion 119a of the pull tab mounting portion 119 is arranged vertically on the upper end portion 112 of the puller body 110, the plate-shaped portion 120 can further extend to the front end side Fr from the space between the front end portion 119a of the pull tab mounting portion 119 and the upper end portion 112 of the puller body 110. In this way, in the case that the puller 100 is provided with the pull tab mounting portion 119, the plate-shaped portion 120 can be formed to extend in the thickness direction T and the length direction L (as shown in Figure 3 and ​ As shown) with high structural strength. However, the relative position of the pull tab mounting portion 119 and the plate-shaped portion 120, the specific structure of the pull tab mounting portion 119, and whether it is provided or not can be adjusted according to requirements, and the utility model is not limited in this regard.

[0075] In the zipper puller, the zipper puller set, and the zipper of the present application, the front end side of the upper end portion of the puller body is provided with a single-layer plate-shaped portion extending forward and offset toward the first side (for example, the outer side) in the width direction. A convex rib portion is formed on the side surface of the front end of the plate-shaped portion corresponding to the second side (for example, the inner side), and the convex rib portion has a fitting surface facing the second side. In this way, when the zipper puller is installed on the zipper chain, the zipper puller can be positioned by the fitting of the convex rib portion with the opposite convex rib portion in the width direction through the twisting of the zipper chain in the length direction (for example, unable to separate in the length direction in the unlocked state), and the fitting of the convex rib portion can be released in the width direction through the release of the twisting of the zipper chain in the length direction (for example, loosening the twisted zipper chain) or reverse twisting. The twisting in the length direction can be achieved by slightly turning the zipper puller in the width direction while sliding it in the length direction, without the need for complex unlocking means such as bending the zipper chain up and down to rotate the zipper puller substantially opposite. Preferably, the extension direction of the plate-shaped portion is inclined forward and to the first side relative to the center line of the puller body in the length direction, so that the zipper puller can more easily fit and release the fitting through the fitting surface in the width direction through the twisting of the zipper chain. Accordingly, the zipper puller, the zipper puller set, and the zipper of the present application can improve the operation smoothness when releasing the lock through a simple operation method.

[0076] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
