Description

Technical Field

[0001] This invention relates to the field of zippers, and more particularly to a zipper pull. Background Technology

[0002] In existing technology, common fasteners typically include a fastener chain consisting of a fastener tape and a pair of fastener stringers with multiple rows of teeth arranged on the fastener tape, and a slider mounted on the fastener tape to open or close the rows of teeth by sliding. A pull tab can also be added to the slider to facilitate sliding along the fastener chain. The slider is usually made as a single unit with an upper and lower flange facing each other, and a pull tab mounting post is provided or formed on the upper surface of the upper flange. Therefore, if a part of either the upper or lower flange is damaged, the entire slider usually needs to be discarded. To address this, a method has been developed to replace a portion of either the upper or lower flange with a replacement slider, allowing for replacement of only the replacement slider when a part of either flange is damaged. However, the currently developed modular zipper pulls, with the zipper pull body and replacement spool connected by a pivot, result in a relatively complex assembly process and low structural strength. Therefore, it is necessary to improve the structure of the zipper pull to enhance its assembly operability and structural strength. Summary of the Invention

[0003] This invention provides a zipper puller with good assembly operability and structural strength.

[0004] The present invention provides a zipper pull, comprising: a zipper pull body including an upper wing plate and a lower wing plate disposed opposite to each other; and a zipper pull replacement piece including a rear opening and a pair of slide rail portions extending from the rear opening to the front side in the length direction and separated from each other, wherein one of the upper wing plate and the lower wing plate has a pair of slide groove portions extending in the length direction corresponding to opposite side edges in the width direction, and the zipper pull replacement piece is mounted on one of the upper wing plate and the lower wing plate by sliding horizontally relative to the zipper pull body along the pair of slide rail portions via the pair of slide groove portions, thus serving as part of one of the upper wing plate and the lower wing plate.

[0005] In the slider of an embodiment of the present invention, a pair of slide rails extend obliquely from the rear opening to the front side in the length direction, and the distance between the pair of slide rails in the width direction gradually increases from the rear opening to the front side. When the slider replacement piece is mounted on one of the upper wing plate and the lower wing plate, the pair of slide rails clamp the opposite side edges of one of the upper wing plate and the lower wing plate that are provided with a pair of slide grooves.

[0006] In the slider of an embodiment of the present invention, each of the pair of slide rail portions has a first groove extending in the width direction, and the first groove is located inside the slide rail portion, so that the slide rail portion is configured to be deformable from the inside to the outside through the first groove.

[0007] In the slider of an embodiment of the present invention, the first groove is disposed on the slide rail portion at a position closer to the rear end than the front end in the length direction.

[0008] In the slider of an embodiment of the present invention, each of the pair of slide rail portions has a second groove extending in the length direction, and the second groove is located at the center of the slide rail portion and connected to the first groove, so that the slide rail portion is configured to be deformable from the inside to the outside through the first groove and the second groove.

[0009] In the slider of an embodiment of the present invention, each of the pair of slide rail portions has a rib extending along the length direction, and when the slider replacement piece is mounted on one of the upper wing plate and the lower wing plate, the rib is fitted into the slide groove portion along the length direction.

[0010] In the slider of an embodiment of the present invention, when the slider replacement piece is installed on one of the upper wing plate and the lower wing plate, the upper and lower surfaces of the rib are covered by the groove portion along the length direction.

[0011] In the slider of an embodiment of the present invention, each of the pair of slide rails has a locking protrusion protruding from the inner side to the inner side at its front end in the length direction, and is mounted on one of the upper wing plate and the lower wing plate by sliding horizontally along the pair of slide rails through the locking protrusion.

[0012] In the slider of an embodiment of the present invention, each of the pair of groove portions has a locking recess at its front end in the length direction, which is recessed from the outer side to the inner side, and the depth of the locking recess is greater than the depth of the groove portion. The slider replacement piece is fixed to one of the upper wing plate and the lower wing plate by the locking protrusion of the slide rail portion engaging with the locking recess of the groove portion.

[0013] In the zipper pull of an embodiment of the present invention, the rear opening of the zipper pull replacement piece is provided with a locking hole at the rear end of the length direction, and one of the upper wing plate and the lower wing plate is provided with a hook at the rear end of the length direction. The zipper pull replacement piece is fixed to one of the upper wing plate and the lower wing plate by engaging the locking hole with the hook.

[0014] In the zipper pull of an embodiment of the present invention, one of the upper wing plate and the lower wing plate has a stepped portion at its rear end in the length direction, and the zipper pull replacement piece is installed on one of the upper wing plate and the lower wing plate, such that at least a portion of the rear opening abuts against the stepped portion.

[0015] In the slider of an embodiment of the present invention, the length of the upper wing plate in the longitudinal direction is less than the length of the lower wing plate in the longitudinal direction, such that the rear end of the upper wing plate in the longitudinal direction is further forward than the rear end of the lower wing plate in the longitudinal direction. The slider replacement piece is installed on the upper wing plate, such that the rear opening abuts against the rear end of the upper wing plate, and the length of the slider replacement piece and the upper wing plate in the longitudinal direction after installation is equivalent to the length of the lower wing plate.

[0016] In the slider of an embodiment of the present invention, the slider replacement piece further includes a protrusion provided on the upper surface of the rear opening. When the slider replacement piece is installed on the upper wing plate, the protrusion and the open end of the slider mounting post provided on the upper surface of the upper wing plate are opposite to each other and form a stop wall located on the rear side of the slider mounting post and the upper wing plate.

[0017] In the slider of an embodiment of the present invention, the protrusion includes an inclined portion extending backward from the front end of the rear opening and a parallel portion extending from the inclined portion toward the rear end of the rear opening, and the distance between the parallel portion and the open end of the slider mounting post in the thickness direction is less than the distance between the inclined portion and the slider mounting post in the thickness direction.

[0018] In the slider of an embodiment of the present invention, in the front-rear direction of the protrusion, the front end of the parallel portion is located further forward than the front end of the open end of the slider mounting post.

[0019] In the zipper pull of an embodiment of the present invention, the materials of the zipper pull body and the zipper pull replacement piece include zinc.

[0020] Based on the above, in the zipper pull of the present invention, the zipper pull replacement piece includes a pair of slide rails extending from the rear opening to the front side in the length direction and separated from each other, and a pair of grooves extending in the length direction are provided on opposite side edges of one of the upper and lower wing plates of the zipper pull body in the width direction. The zipper pull replacement piece is mounted on one of the upper and lower wing plates by sliding horizontally relative to the zipper pull body along the pair of grooves via the pair of slide rails, thus serving as part of one of the upper and lower wing plates. In this way, the zipper pull replacement piece can be easily installed not only by sliding horizontally along the pair of grooves via the separated pair of slide rails, but also by clamping the opposite side edges of one of the upper and lower wing plates via the pair of slide rails. Accordingly, the zipper pull of the present invention has good assembly operability and structural strength.

[0021] To make the above features and advantages of the present invention more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings. Attached Figure Description

The following will be paired with... Figures 1 to 4C This invention describes the specific structure and assembly method of a zipper puller 100 according to an embodiment of the present invention, and provides an explanation of its specific structure and assembly method. Figure 5 The specific structure of the slider 100A in other variations of the present invention will be explained, and it will be paired with... Figures 6 to 8 The specific structure of the slider 100B in another embodiment of the present invention is described, but the present invention is not limited thereto and can be adjusted according to requirements.

[0069] Please refer to Figures 1 to 3In this embodiment, the zipper pull 100 includes a zipper pull body 110 and a zipper pull replacement piece 120. The zipper pull body 110 includes an upper wing plate 112 and a lower wing plate 114 disposed opposite to each other. The zipper pull replacement piece 120 includes a rear opening 122 and a pair of slide rails 124 extending from the rear opening 122 toward the front side S1 in the length direction L (corresponding to the front-rear direction) and separated from each other. The upper wing plate 112 and the lower wing plate 114 (taking the upper wing plate 112 as an example) have a pair of grooves 112g extending in the length direction L on their opposite side edges 112s in the width direction W (corresponding to the left-right direction). The zipper pull replacement piece 120 slides horizontally relative to the zipper pull body 110 along the pair of grooves 112g via the pair of slide rails 124. Figure 1 and Figure 2 (as shown in the state change), and is installed on one of the upper wing plate 112 and the lower wing plate 114 (upper wing plate 112) as part of one of the upper wing plate 112 and the lower wing plate 114 (upper wing plate 112).

[0070] Specifically, in this embodiment, as Figure 1 and Figure 2 As shown, the upper wing plate 112 and the lower wing plate 114 of the slider body 110 are connected to each other via guide posts 113 at their front ends S1 in the longitudinal direction L, and the rear ends S2 in the longitudinal direction L of the upper wing plate 112 and the lower wing plate 114 are open, thereby forming a chain tooth channel 115 between the upper wing plate 112 and the lower wing plate 114 and on both sides of the guide posts 113. Furthermore, the upper surface of the upper wing plate 112 is provided with a slider mounting post 116 extending from the front end S1 to the rear end S2 and forming a cantilever at the rear end S2 (but not limited thereto). Here, the example of the slider replacement piece 120 being mounted on the upper wing plate 112 of the slider body 110 will be described. In this design, the upper wing plate 112, except for its base 117 which connects to the guide post 113 and the pull tab mounting post 116, has a plate surface portion and flange portions 118 on opposite sides corresponding to the chain tooth channel 115 on the zipper head replacement piece 120. Therefore, a portion of the upper wing plate 112 of the zipper head body 110 (e.g., ...) can be replaced by the zipper head replacement piece 120. Figure 2 (As shown). However, in other embodiments not shown, the slider replacement piece 120 may also be used to replace a portion of the lower wing plate 114. The present invention does not limit the specific structure of the slider body 110, which can be adjusted as needed.

[0071] Furthermore, in this embodiment, as Figures 1 to 3As shown, the rear opening 122 of the slider replacement piece 120 is open, corresponding to the rear end of the lower wing plate 114 on the rear side S2. A pair of slide rail portions 124 of the slider replacement piece 120 extend from the rear opening 122 towards the front side S1 in the length direction L and are separated from each other. The flange portion 118, as described above, is provided on opposite sides of the slider replacement piece 120 in the width direction W, and extends from the rear opening 122 towards the front side S1, at least partially corresponding to the outer side of the pair of slide rail portions 124 (but not limited thereto). In contrast, opposite side edges 112s of the upper wing plate 112 in the width direction W are provided on the base 117 and are substantially parallel to each other, while a pair of groove portions 112g extending in the length direction L are correspondingly provided on the opposite side edges 112s and are substantially parallel to each other. Preferably, the pair of groove portions 112g provided on the opposite side edges 112s are substantially parallel to the surface direction of the upper wing plate 112 and the lower wing plate 114. Thus, the replacement slider 120 can slide horizontally relative to the slider body 110 via a pair of separate slide rails 124 along a pair of slide grooves 112g, and be installed from the opposite two side edges 112s in the width direction W of the slider body 110.

[0072] As an example, in this embodiment, such as Figures 4A to 4C As shown, the assembly method of the slider 100 is as follows. When the slider replacement piece 120 is installed on the slider body 110 from the rear side S2 of one of the upper wing plate 112 and the lower wing plate 114 (taking the upper wing plate 112 as an example) (e.g.) Figure 1 and Figure 4A In the state shown), the pair of slide rails 124 of the pull head replacement piece 120 first contact the rear ends of the pair of grooves 112g provided on the opposite side edges 112s of the upper wing plate 112 (corresponding to the ends of the rear side S2), and then the pair of slide rails 124 slide along the pair of grooves 112g towards the front side S1 (as shown). Figure 4B (as shown in the diagram), until the pair of slide rails 124 slide to the front end of the pair of slide grooves 112g (corresponding to the end of the front side S1) (as shown in the diagram). Figure 2 and Figure 4C (As shown in the diagram). When the slider replacement piece 120 is installed on one of the upper wing plate 112 and the lower wing plate 114 (upper wing plate 112), the slider replacement piece 120 can form a complete slider 100 as part of one of the upper wing plate 112 and the lower wing plate 114 (upper wing plate 112). Figure 2 and Figure 4C(As shown in the diagram). That is, the assembled zipper pull 100 can be mounted on a zipper chain (not shown) and the zipper chain can be opened or closed by sliding. In contrast, when a portion of one of the upper wing plate 112 and the lower wing plate 114 (upper wing plate 112) is damaged, the zipper pull replacement piece 120 can be removed by sliding in the reverse direction, that is, the zipper pull replacement piece 120 slides horizontally relative to the zipper pull body 110 from the front side S1 to the rear side S2 via a pair of slide rails 124 along a pair of slide grooves 112g (as shown in the diagram). Figure 1 and Figure 4A (As shown) and then replace.

[0073] With the above configuration, in the swivel head 100 of this embodiment, the swivel head replacement piece 120 includes a pair of slide rails 124 that extend from the rear opening 122 toward the front side S1 in the length direction L and are separated from each other. The upper wing plate 112 and the lower wing plate 114 of the swivel head body 110 (taking the upper wing plate 112 as an example) have a pair of grooves 112g extending in the length direction L on their opposite side edges 112s in the width direction W. The swivel head replacement piece 120 slides horizontally relative to the swivel head body 110 along the pair of grooves 112g via the pair of slide rails 124, and is mounted on one of the upper wing plate 112 and the lower wing plate 114 (the upper wing plate 112), thus serving as a part of the upper wing plate 112 and the lower wing plate 114 (the upper wing plate 112). Thus, the zipper pull replacement piece 120 can be easily installed not only by sliding horizontally along a pair of grooves 112g via a pair of separate slide rails 124, but also by clamping the opposite side edges 112s of one of the upper wing plate 112 and the lower wing plate 114 (the upper wing plate 112) with the slide rails 124. Accordingly, the zipper pull 100 of this embodiment has good assembly operability and structural strength.

[0074] Furthermore, in this embodiment, as Figures 1 to 3 As shown, a pair of slide rail portions 124 extend obliquely from the rear opening 122 towards the front side S1 in the length direction L, and the distance between the pair of slide rail portions 124 in the width direction W gradually increases from the rear opening 122 towards the front side S1 (they are not parallel to each other). That is, the distance D1 between the rear ends P2 of the pair of slide rail portions 124 connected to the rear opening 122 is smaller than the distance D2 between the front ends P1 of the opposite rear opening 122, so that the pair of slide rail portions 124 gradually expand outward in the width direction W from the rear end P2 towards the front end P1 in the length direction L (as shown). Figure 3 (As shown). With the slider replacement piece 120 sliding horizontally relative to the slider body 110 via a pair of slide rails 124 along a pair of grooves 112g, the pair of slide rails 124 first contact the rear end of the pair of grooves 112g corresponding to the rear side S2 at the front end P1, which is larger than D2 (as shown). Figure 1and Figure 4A (as shown in the diagram), then slide forward on the S1 until the rear end P2, which is smaller than D1, also contacts the rear end of the pair of grooves 112g corresponding to the rear end of the rear side S2 (as shown in the diagram). Figure 2 and Figure 4C (As shown in the diagram). With the pull head replacement piece 120 installed on one of the upper wing plate 112 and the lower wing plate 114 (taking the upper wing plate 112 as an example), a pair of slide rails 124 clamp the opposite side edges 112s of one of the upper wing plate 112 and the lower wing plate 114 (the upper wing plate 112) that are provided with a pair of slide grooves 112g.

[0075] Furthermore, in this embodiment, as Figures 1 to 3 As shown, each of the pair of slide rail portions 124 has a first groove 124n1 extending in the width direction W, and the first groove 124n1 is located inside the slide rail portion 124, so that the slide rail portion 124 is configured to deform from the inside to the outside through the first groove 124n1. Furthermore, the first groove 124n1 is located in the length direction L of the slide rail portion 124 closer to the rear end P2 than the front end P1. That is, the first groove 124n1 extends from the inside of the slide rail portion 124 towards the middle of the slide rail portion 124 but does not extend to the outside of the slide rail portion 124 (it does not cut the entire slide rail portion 124 along the width direction W). During the sliding of the pair of slide rail portions 124 along the groove portion 112g towards the front side S1, the pair of slide rail portions 124, pushed by the opposite side edges 112s, can be deformed from the inside to the outside by flipping with the first groove 124n1 near the rear end P2 as a reference point (e.g., Figure 3 As shown by the arrow, the pair of slide rails 124 can, during the sliding towards the forward side S1, have their inner surfaces in the width direction W more closely conform to the contours of the opposite side edges 112s where the groove portion 112g is provided. Thus, the zipper pull 100 not only sets the pair of slide rails 124 to extend obliquely outward from the rear opening 122 towards the forward side S1 in the length direction L, but also provides a first groove 124n1 near the rear end P2 of the pair of slide rails 124 connected to the rear opening 122. This allows for smoother sliding of the zipper pull replacement piece 120 and improves the clamping effect of the pair of slide rails 124, thereby enhancing the structural strength of the zipper pull 100. The above description of the pair of slide rails 124 (obliquely set and extending outward, providing a first groove 124n1 to facilitate outward deformation) can be adjusted according to requirements, and the present invention is not limited thereto.

[0076] In contrast, Figure 5In the modified slider 100A shown, the slider replacement piece 120A has a similar structure to the aforementioned slider replacement piece 120, but with the following differences: A pair of slide rail portions 124A of the slider replacement piece 120A extend vertically from the rear opening 122 towards the front side S1 in the length direction L, and the distance D between the pair of slide rail portions 124A in the width direction W remains approximately the same from the rear opening 122 towards the front side S1 (parallel to each other). Furthermore, each pair of slide rail portions 124A has a first groove 124n1 extending in the width direction W and located inside the slide rail portion 124A, and the first groove 124n1 is positioned closer to the rear end P2 of the slide rail portion 124A in the length direction L. Furthermore, each of the pair of slide rail portions 124A has a second groove 124n2 extending in the length direction L. The second groove 124n2 is located at the center of the slide rail portion 124A and connects to the first groove 124n1, so that the slide rail portion 124A is configured to deform from the inside to the outside through the first groove 124n1 and the second groove 124n2. That is, the second groove 124n2 extends from the center of the slide rail portion 124A to the front side S1 and the rear side S2, but does not extend to the front end P1 and the rear end P2 of the slide rail portion 124A (it does not cut the entire slide rail portion 124A along the length direction L), and the second groove 124n2 connects to the first groove 124n1 to form a T-shaped groove.

[0077] Therefore, it can be concluded that in Figure 5 In the modified example shown, the slider replacement piece 120A replaces the aforementioned slider replacement piece 120 and is installed as follows: Figures 1 to 3 In the case of the slider body 110 shown, as the pair of slide rails 124A slide along the slide groove 112g towards the forward side S1, the pair of slide rails 124A, pushed by the opposite side edges 112s, can be deformed from the inside to the outside by using the T-shaped groove formed by the first groove 124n1 near the rear end P2 and the second groove 124n2 connected to the first groove 124n1 as a reference point (e.g. Figure 5 As shown by the arrow, the pair of slide rails 124A can, during the forward sliding process S1, have their inner surfaces in the width direction W more closely conform to the contours of the opposite side edges 112s where the slide groove 112g is provided. Thus, compared to the aforementioned pull head 100, Figure 5In the modified example shown, the slider replacement piece 120A of the slider 100A not only has a first groove 124n1 near the rear end P2 of the pair of slide rails 124A connected to the rear opening 122, but also has a second groove 124n2 extending in the length direction L and connected to the first groove 124n1 in the center of the pair of slide rails 124A. This allows the slider replacement piece 120A to slide more smoothly and improves the clamping effect of the pair of slide rails 124A, thereby improving the structural strength of the slider 100. The above description of the pair of slide rails 124A (the provision of the first groove 124n1 and the second groove 124n2 to facilitate outward deformation) can be adjusted according to requirements, and the present invention is not limited thereto.

[0078] Additionally, in this embodiment, as Figures 1 to 3 As shown, each of the pair of slide rail portions 124 has a protruding rib 124r extending along the length direction L. When the pull head replacement piece 120 is mounted on one of the upper wing plate 112 and the lower wing plate 114 (taking the upper wing plate 112 as an example), the protruding rib 124r engages with the slide groove portion 112g along the length direction L. As an example, the protruding rib 124r is provided on the inner side of the slide rail portion 124 and protrudes inward from the inner side, and is located on the slide rail portion 124 at a position closer to the rear side S2 in the length direction L than the first cut groove 124n1. During the sliding of the pair of slide rail portions 124 along the slide groove portion 112g towards the front side S1, as... Figures 4A to 4C As shown, a pair of slide rails 124 can be deformed by flipping from the inside to the outside with the first groove 124n1 near the rear end P2 as a reference point (e.g. Figure 3 As shown by the arrow, the rib 124r then enters the groove portion 112g from its rear end (corresponding to the end of the rear side S2) and slides along the groove portion 112g towards the front side S1 until it reaches the front end of the groove portion 112g (corresponding to the end of the front side S1). Furthermore, with the pull head replacement piece 120 mounted on one of the upper wing plate 112 and the lower wing plate 114 (the upper wing plate 112), the upper and lower surfaces of the rib 124r are covered by the groove portion 112g along the length direction L. That is, the rib 124r overlaps with the groove portion 112g in the vertical direction (corresponding to the thickness direction T).

[0079] Therefore, in this embodiment, the rib 124r, which is located closer to the rear side of the slide rail portion 124 than the first groove 124n1, does not affect the deformation action of the slide rail portion 124, which flips from the inside to the outside through the first groove 124n1 during the sliding of the slider replacement piece 120. Furthermore, as the rib 124r slides forward S1 along the groove portion 112g, its upper and lower surfaces are covered by the groove portion 112g along the length direction L, thus limiting the sliding of the rib 124r in the vertical direction (corresponding to the thickness direction T) by the inner side of the groove portion 112g. In this way, the rib 124r can act as a guide to maintain the horizontal sliding of the pair of slide rail portions 124 as they slide along the pair of groove portions 112g, making the sliding of the slider replacement piece 120 smoother and improving the assembly operability of the slider 100. The above description regarding the rib 124r also applies to... Figure 5 The specific structure of the pair of slide rails 124A of the pull head replacement piece 120A shown, and whether or not the ribs 124r are provided, can be adjusted as needed, and the present invention is not limited thereto.

[0080] Similarly, in this embodiment, as Figures 1 to 3 As shown, each of the front ends P1 of a pair of slide rails 124 in the longitudinal direction L has an engaging protrusion 124p protruding inward from the inner side, and slides horizontally along a pair of slide grooves 112g via the engaging protrusion 124p, and is mounted on one of the upper wing plate 112 and the lower wing plate 114 (taking the upper wing plate 112 as an example). During the sliding of the pair of slide rails 124 along the slide grooves 112g towards the forward side S1, as... Figures 4A to 4C As shown, the pair of slide rail portions 124 first contact the rear end of the slide groove portion 112g (corresponding to the end on the rear side S2) with the engaging protrusion 124p provided at the front end P1. Then, the engaging protrusion 124p enters the slide groove portion 112g and slides forward to the front side S1 until it reaches the front end of the slide groove portion 112g (corresponding to the end on the front side S1). In this way, the engaging protrusion 124p can act as a guide to maintain the horizontal sliding of the pair of slide rail portions 124 as they slide along the pair of slide groove portions 112g, making the sliding of the slider replacement piece 120 smoother and improving the assembly operability of the slider 100. The above description of the engaging protrusion 124p also applies to... Figure 5 The specific structure of the pair of slide rails 124A and the engagement protrusion 124p shown in the pull head replacement piece 120A, as well as whether or not they are provided, can be adjusted according to requirements, and the present invention is not limited thereto.

[0081] Therefore, in this embodiment, as Figures 1 to 3As shown, each of the pair of sliding groove portions 112g has a locking recess 112r that is recessed from the outer side to the inner side at its front end (corresponding to the end of the front side S1) in the longitudinal direction L. Figure 1 (as indicated by the reference numeral), and the depth of the engaging recess 112r is greater than the depth of the sliding groove 112g. That is, the engaging recess 112r is recessed further inward towards the opposite side edges 112s than the sliding groove 112g. During the sliding of the pair of slide rails 124 along the sliding groove 112g towards the front side S1, as... Figures 4A to 4C As shown, a pair of slide rails 124 first enter the slide groove 112g from the rear end (corresponding to the rear end of the rear side S2) through the engaging protrusion 124p provided at the front end P1, and then slide forward to the front end (corresponding to the front end of the front side S1) of the slide groove 112g. Then, the pull head replacement piece 120 is fixed to one of the upper wing plate 112 and the lower wing plate 114 (taking the upper wing plate 112 as an example) by engaging the engaging protrusion 124p of the slide rail 124 with the engaging recess 112r of the slide groove 112g.

[0082] As an example, in this embodiment, such as Figures 1 to 3 As shown, the front end of the slide groove 112g (corresponding to the end of the front side S1) is provided with an inclined wall 112w, and the front side S1 of the inclined wall 112w is recessed inward to form a locking recess 112r. After a pair of slide rails 124 slide along the slide groove 112g towards the front side S1 to the front end of the slide groove 112g (corresponding to the end of the front side S1), the locking protrusion 124p slides towards the front side S1 and passes through the inclined wall 112w, and the slide rail 124 is pushed by the inclined wall 112w and deforms from the inside to the outside. After the locking protrusion 124p passes through the inclined wall 112w, the slide rail 124 is released from the push of the inclined wall 112w and flips inward to reset, and the locking protrusion 124p further enters the locking recess 112r provided on the front side S1 of the inclined wall 112w to engage. However, the inclined wall 112w can be omitted, and a more inwardly recessed engaging recess 112r can be formed at the front end of the slide groove 112g (corresponding to the end of the front side S1). In this way, the engaging protrusion 124p can not only serve as a guide during the sliding of the pair of slide rails 124, but also engage with the engaging recess 112r to improve the fixing effect of the slider replacement piece 120 on the slider body 110, thereby further improving the structural strength of the slider 100. The above description regarding the engaging recess 112r also applies to... Figure 5 The specific structure of the pair of slide rails 124A and the engagement recess 112r shown in the pull head replacement piece 120A, as well as whether or not they are provided, can be adjusted according to requirements, and the present invention is not limited thereto.

[0083] Similarly, in this embodiment, as Figures 1 to 3As shown, the rear opening 122 of the pull tab replacement piece 120 has a locking hole 126 at its rear end (corresponding to the rear end of the rear side S2) in the longitudinal direction L. One of the upper wing plate 112 and the lower wing plate 114 (taking the upper wing plate 112 as an example) has a hook 112h at its rear end (corresponding to the rear end of the rear side S2) in the longitudinal direction L. Thus, after the pair of slide rail portions 124 slide along the slide groove portion 112g towards the front side S1, as... Figure 2 and Figure 4C As shown, the hook 112h provided on one of the upper wing plate 112 and the lower wing plate 114 (upper wing plate 112) passes through the locking hole 126 provided on the rear opening 122 of the slider replacement piece 120. Furthermore, the slider replacement piece 120 is fixed to one of the upper wing plate 112 and the lower wing plate 114 (upper wing plate 112) by engaging the locking hole 126 with the hook 112h. Thus, the locking hole 126 and the hook 112h provided at the rear end (corresponding to the rear side S2) do not affect the sliding action of the pair of slide rails 124 along the slide groove 112g towards the front side S1, and can also engage with each other after the slider replacement piece 120 is installed on the slider body 110, thereby improving the fixing effect of the slider replacement piece 120 on the slider body 110, and further enhancing the structural strength of the slider 100. The above description regarding the locking hole 126 also applies to... Figure 5 The specific structure of the pair of slide rails 124A of the pull head replacement piece 120A shown, as well as the specific configuration of the locking hole 126 and the locking hook 112h, and whether or not they are set, can be adjusted according to requirements. This invention is not limited thereto.

[0084] Furthermore, in this embodiment, as Figure 1 As shown, one of the upper wing plate 112 and the lower wing plate 114 (taking the upper wing plate 112 as an example) has a stepped portion 112t at its rear end (corresponding to the rear side S2) in the longitudinal direction L, and the pull head replacement piece 120 is installed on one of the upper wing plate 112 and the lower wing plate 114 (the upper wing plate 112), so that at least a portion of the rear opening 122 abuts against the stepped portion 112t. That is, a stepped portion 112t with a thickness thinner than the base 117 is formed on the rear end of one of the upper wing plate 112 and the lower wing plate 114 (the upper wing plate 112) that is connected to the pull head replacement piece 120. Furthermore, with the replacement slider 120 mounted on one of the upper wing plate 112 and the lower wing plate 114 (upper wing plate 112), the front end of the rear opening 122 (corresponding to the end on the front side S1) is connected to the rear end of the base 117 (corresponding to the end on the rear side S2) (as shown). Figure 2As shown), the stepped portion 112t overlaps at least a portion of the rear opening 122 in the vertical direction (corresponding to the thickness direction T). Thus, the stepped portion 112t can support at least a portion of the rear opening 122 in the vertical direction (corresponding to the thickness direction T), improving the fixing effect of the slider replacement piece 120 on the slider body 110, thereby further enhancing the structural strength of the slider 100. The above description regarding the stepped portion 112t also applies to... Figure 5 The specific structure of the pair of slide rails 124A and the step portion 112t shown in the pull head replacement piece 120A, as well as whether or not they are provided, can be adjusted according to requirements, and the present invention is not limited thereto.

[0085] Therefore, in this embodiment, as Figures 1 to 3 As shown, the slider 100 is described using the example of mounting the slider replacement piece 120 on the upper wing plate 112 of the slider body 110. Here, as... Figure 1 As shown, the length L1 of the upper wing 112 in the longitudinal direction L is less than the length L2 of the lower wing 114 in the longitudinal direction L, so that the rear end of the upper wing 112 (corresponding to the rearward end S2) in the longitudinal direction L is further forward on the forward side S1 than the rear end of the lower wing 114 (corresponding to the rearward end S2) in the longitudinal direction L. That is, based on the front ends (corresponding to the forward end S1) of the upper wing 112 and the lower wing 114, the upper wing 112 is shorter than the lower wing 114. Furthermore, as Figure 2 As shown, the replacement slider 120 is mounted on the upper wing plate 112, such that the rear opening 122 abuts against the rear end of the upper wing plate 112, and the length L3 of the replacement slider 120 and the upper wing plate 112 in the longitudinal direction L is equivalent to the length L2 of the lower wing plate 114. Figure 1 Thus, the zipper pull replacement piece 120 can be considered as a replacement for the upper flange 112 of the zipper pull body 110, forming a complete zipper pull 100 (the lengths of the upper and lower sides are approximately equal, making the ends of the front side S1 and the rear side S2 flush). The above installation instructions regarding the zipper pull replacement piece 120 also apply to... Figure 5 The slider replacement piece 120A shown is also applicable to replacing a portion of the lower wing plate 114 by mounting the slider replacement piece 120 onto a lower wing plate 114 that is configured to be shorter than the upper wing plate 112. It can be adjusted as needed, and the present invention is not limited thereto.

[0086] In this embodiment, the slider body 110 and the slider replacement piece 120 are manufactured separately and then installed in the manner described above to form a complete slider 100. Preferably, the slider body 110 and the slider replacement piece 120 are made of zinc. Using zinc as the slider body 110 and the slider replacement piece 120 can improve the structural strength of the slider 100, and can make the pair of slide rail portions 124 of the slider replacement piece 120 have the elastic deformation material properties required when installed on one of the upper flange 112 and the lower flange 114 (upper flange 112). Furthermore, when using zinc as the slider replacement piece 120, after the slider replacement piece 120 is installed on the slider body 110, the slider replacement piece 120 can be crimped and reinforced to improve the structural strength, but this is not a limitation. In other embodiments not shown, resin materials or the like can be used for the slider body 110 and the slider replacement piece 120, so that the pair of slide rail portions 124 of the slider replacement piece 120 have the material properties of elastic deformation required during installation. Furthermore, when using resin material as the slider replacement piece 120, the slider replacement piece 120 can be installed on the slider body 110 by the elastic force of the resin material (snap-fit ​​installation) without the need for crimping reinforcement of the slider replacement piece 120.

[0087] Therefore, it can be seen that by using a material with elastic deformation properties (such as zinc or resin) to make the slider replacement piece 120, regardless of whether the pair of slide rails 124 extend at an angle or whether the first groove 124n1 is provided, during the process of the pair of slide rails 124 sliding along the pair of grooves 112g towards the front side S1, the pair of slide rails 124 can be pushed by the opposite side edges 112s and deformed from the inside to the outside by the elastic deformation material properties. Thus, during the process of sliding towards the front side S1, the inner surface of the pair of slide rails 124 in the width direction W can better fit the contour of the opposite side edges 112s where the grooves 112g are provided, and the opposite side edges 112s can be clamped by elastic reset. This makes the sliding of the slider replacement piece 120 smoother and improves the clamping effect of the pair of slide rails 124, thereby improving the structural strength of the slider 100. The above description of the material of the slider replacement piece 120 also applies to... Figure 5 The slider replacement piece 120A is shown. However, the slider body 110 and the slider replacement piece 120 are not limited to being made of the materials described above; different materials can also be used to make the slider body 110 and the slider replacement piece 120. The present invention does not limit the materials or fixing methods of the slider body 110 and the slider replacement piece 120, which can be adjusted according to requirements.

[0088] Please refer to Figures 6 to 8 In another embodiment of the present invention, the zipper pull 100B includes a zipper pull body 110 and a zipper pull replacement piece 120B, wherein the zipper pull replacement piece 120B is different from... Figures 1 to 4C The aforementioned zipper pull replacement piece 120 and as follows Figure 5 The slider replacement piece 120A shown can also be mounted on the slider body 110. For a description of the slider body 110 (specific structure, material, etc.), please refer to the foregoing content; further details will not be repeated here. Furthermore, the slider replacement piece 120B includes a rear opening 122 and a pair of separate slide rails 124A extending from the rear opening 122 towards the front side S1 in the longitudinal direction L. The slider replacement piece 120B slides horizontally relative to the slider body 110 along a pair of grooves 112g of the slider body 110 via the pair of slide rails 124A (e.g., ...). Figure 1 and Figure 2 (As shown in the state change), it is installed on the upper wing plate 112 as part of the upper wing plate 112. For a description of the rear opening 122 and the pair of slide rails 124A (specific structure, material, installation method, etc.), please refer to the foregoing content; further details will not be repeated here. Furthermore, although the pull head replacement piece 120B is shown here, it adopts... Figure 5 The pair of slide rail portions 124A shown (having a first groove 124n1 and a second groove 124n2 forming a T-shaped groove) may also have a slider replacement piece 120B, as shown in other embodiments not shown. Figure 1 The invention is not limited to this, and can be adjusted as needed. (The slide rails 124 shown in Figure 4 are inclined and have a first groove.)

[0089] Specifically, in this embodiment, as Figures 6 to 8 As shown, the slider replacement piece 120B also includes a protrusion 128 provided on the upper surface of the rear opening 122. When the slider replacement piece 120B is mounted on the upper wing plate 112 (as described above, it is mounted by sliding horizontally relative to the slider body 110 along a pair of slide rails 124A along a pair of slide grooves 112g), the protrusion 128 faces the open end 116a (i.e., the end forming the cantilever) of the slider mounting post 116 provided on the upper surface of the upper wing plate 112 on the rear side, forming a stop wall (such as...) located on the rear side of the slider mounting post 116 and the upper wing plate 112. Figure 6 and Figure 7 As shown). That is to say, as Figure 6 and Figure 7As shown, the pull tab mounting post 116 is spaced apart from the upper surface of the upper wing plate 112 in the thickness direction T, and the rear side of the pull tab mounting post 116 forms an open end 116a with a cantilever, so that the gap between the open end 116a and the upper wing plate 112 in the thickness direction T allows the mounting ring of the pull tab (not shown) to pass through for installation. When the pull tab replacement piece 120B is installed on the upper wing plate 112, the gap between the open end 116a and the upper wing plate 112 can be substantially closed by the protrusion 128 provided on the upper surface of the rear opening 122 of the pull tab replacement piece 120B (not limited to complete closure, as long as the gap between the protrusion 128 and the open end 116a is smaller than the size through which the mounting ring of the pull tab can pass after the pull tab replacement piece 120B is installed), thereby preventing the installed pull tab from slipping off the open end 116a. In this way, the stop for closing the gap between the open end 116a of the pull tab mounting post 116 and the upper wing plate 112 can be omitted.

[0090] Furthermore, in this embodiment, as Figures 6 to 8As shown, the protrusion 128 includes an inclined portion 128a extending rearward from the front end of the rear opening 122, and a parallel portion 128b extending from the inclined portion 128a toward the rear end of the rear opening 122. The inclined portion 128a gradually rises (i.e., tilts upward) from the front end of the rear opening 122 toward the rearward side S2. Furthermore, the inclined portion 128a can extend further from the front end of the rear opening 122 toward a pair of slide rail portions 124A. That is, the inclined portion 128a is generally Y-shaped. Moreover, the parallel portion 128b is approximately at the same height as the rear end of the inclined portion 128a and has an upper surface that is parallel to and planar relative to the upper wing plate 112, for the open end 116a of the pull tab mounting post 116 to rest against (but not limited to the open end 116a necessarily contacting the upper surface of the parallel portion 128b; this can be adjusted based on actual assembly results and manufacturing tolerances). Furthermore, the distance t1 between the parallel portion 128b and the open end 116a of the pull tab mounting post 116 in the thickness direction T is smaller than the distance t2 between the inclined portion 128a and the pull tab mounting post 116 in the thickness direction T. Thus, due to the inclined arrangement of the inclined portion 128a, the pull tab replacement piece 120B with the protrusion 128 can be easily installed on the upper wing plate 112 from the rear side S2 to the front side S1 without interference between the protrusion 128 and structures such as the pull tab mounting post 116 during installation. Moreover, due to the protrusion of the parallel portion 128b, a stop wall can be formed at the open end 116a of the pull tab mounting post 116 to substantially close the gap between the open end 116a and the upper wing plate 112 (not limited to complete closure). However, in other embodiments not shown, the inclined portion 128a of the protrusion 128 may also be configured to gradually decrease from the front end of the rear opening 122 towards the rear side S2 (i.e., inclined downwards). The present invention does not limit the specific structure of the protrusion 128, or whether it is provided or not, and it can be adjusted according to the requirements.

[0091] Furthermore, in this embodiment, such as Figure 7As shown, in the front-rear direction of the protrusion 128, the front end of the parallel portion 128b is located further forward than the front end of the open end 116a of the pull tab mounting post 116. That is, the inclined portion 128a begins to incline from a position further forward than the front end of the open end 116a, and the entire open end 116a corresponds to the parallel portion 128b. As an example, the maximum distance between the platform portion 128b and the open end 116a of the pull tab mounting post 116 (i.e., the maximum value of the spacing t1) is greater than the axial width of the pull tab mounting ring. Thus, when the pull tab mounting ring is mounted to the pull tab mounting post 116, the pull tab mounting ring can be supported by the open end 116a of the pull tab mounting post 116 and rest against the parallel portion 128b. When a pulling force is applied to the pull tab, the pulling force can be borne by the pull tab mounting post 116, which has a stronger structural strength, rather than by the pull head replacement piece 120, which is beneficial to the improvement of the overall structural strength. However, the present invention does not limit the specific structure of the parallel portion 128b of the protrusion 128, or whether it is provided or not, which can be adjusted according to needs.

[0092] In summary, in the zipper pull of the present invention, the zipper pull replacement piece includes a pair of slide rails extending from the rear opening towards the front in the length direction and separated from each other, and a pair of grooves extending in the length direction are provided on opposite side edges of the upper and lower wing plates of the zipper pull body in the width direction. The zipper pull replacement piece is mounted on one of the upper and lower wing plates by sliding horizontally relative to the zipper pull body along the pair of slide rails and the pair of grooves, thus serving as part of one of the upper and lower wing plates. In this way, the zipper pull replacement piece can not only be easily installed by sliding horizontally along the pair of grooves via the separated pair of slide rails, but it can also be installed by clamping the opposite side edges of one of the upper and lower wing plates with the pair of slide rails. Preferably, the pair of slide rails extend obliquely towards the front, and the distance in the width direction gradually increases towards the front, thereby further improving the clamping force. Furthermore, each of the pair of slide rail portions has a first groove extending in the width direction and located on the inner side of the slide rail portion, so that the slide rail portion is configured to deform from the inside to the outside through the first groove, thereby further improving the assembly operability of the zipper pull. Accordingly, the zipper pull of the present invention has good assembly operability and structural strength.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention 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; and these 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 the present invention.
