Description

Technical Field

[0001] The present invention relates to the technology of the zipper field, and in particular to a slider. Background Art

[0002] A common zipper usually includes a pair of zipper chains (fastener chains) composed of a strip-shaped fastener tape and a plurality of element columns arranged on the zipper tape, and a slider installed on the zipper chain to open or close the element columns by sliding, and a tab pull can also be set on the slider according to needs. In addition, a locking claw (lock pin) can be set on the slider body of the slider to lock the slider on the zipper chain through the locking claw. For example, the locking claw extends downward through the claw hole of the slider body and is inserted into the element column or zipper tape provided on the zipper chain. The locking method may vary depending on the type of zipper, slider or locking claw. In addition, whether the locking claw is inserted or not can be linked with the slider, for example, when the slider is pulled to drive the slider, the slider simultaneously drives the locking claw to unlock. The unlocking method may vary depending on the type of zipper, slider or locking claw.

[0003] Furthermore, in the prior art, the zipper chain is also provided with a separable pin and a retainer pin. The separable pin and the retainer pin are respectively arranged on a pair of zipper tapes and located at the ends of a pair of chain teeth. Moreover, the separable pin and the retainer pin can be engaged with each other to fix the end of the zipper chain. In this way, when the slider is installed on the zipper chain, the slider opens or closes the chain teeth by sliding relative to the zipper chain. When the slider moves to the end of the zipper chain, the separable pin and the retainer pin are inserted into the slider body from bottom to top and pass through the chain tooth channels respectively. At this time, if the locking claw is arranged on one side of the slider body to avoid low locking strength so that the locking claw can be inserted into the chain teeth on one side, the locking claw will interfere with the insertion of the separable pin. Correspondingly, if the locking claw is arranged in the center of the slider body to avoid interference with the insertion of the separable pin, the locking claw can only be inserted between a pair of chain teeth, resulting in low locking strength. Thus, it is necessary to improve the structures of the slider body and the locking claw of the slider.

[0007] [Patent Document 2] China Utility Model Publication No. 201691193U Summary of the invention

[0008] The present invention provides a slider which can take into account both the locking strength of a locking claw and the insertion effect of an inserting rod, thereby having good operability.

[0009] The present invention provides a slider, which is suitable for being installed on a zipper chain, and comprises: a slider body, comprising an upper wing plate and a lower wing plate arranged opposite to each other, and a guide column connecting the upper wing plate and the lower wing plate, and having a chain tooth channel located between the upper wing plate and the lower wing plate; a locking claw arranged on the slider body; and a pull tab, which is arranged on the slider body and can drive the locking claw to move, wherein the slider body comprises a pair of wall portions arranged on the upper wing plate and forming a accommodating space for the locking claw, a claw hole formed between the pair of wall portions and connected to the chain tooth channel, and at least one claw hole arranged between the pair of wall portions The locking claw is supported by a seat portion on one side of the claw hole and on one of the pair of wall portions, and the locking claw comprises a holding portion held on the front side of the slider body, a loading portion on the opposite side of the holding portion and loaded on the seat portion, and a claw portion extending downward from the loading portion and passing through the claw hole, the seat portion and one of the loading portions being provided with a limiting portion for limiting the loading portion in the width direction, and a gap portion for moving the loading portion is provided above the seat portion in the accommodating space, and the loading portion is spaced apart from the inner wall of one of the pair of wall portions to form the gap portion.

[0010] In an embodiment of the present invention, the gap portion is located above the limiting portion in the up-down direction.

[0011] In an embodiment of the present invention, the limiting portion is disposed on a side of the base portion opposite to the claw hole, and limits the displacement of the mounting portion relative to the base portion in the width direction.

[0012] In an embodiment of the present invention, the limiting portion includes an inclined surface that is inclined downward toward the base portion on which the mounting portion is mounted.

[0013] In an embodiment of the present invention, the limiting portion is provided on one side of the mounting portion adjacent to the claw portion, and limits displacement of the mounting portion relative to the pedestal portion in the width direction.

[0014] In an embodiment of the present invention, the limiting portion includes an inclined surface which is inclined downward from the mounting portion toward the claw portion.

[0015] In an embodiment of the present invention, the loading portion and the claw portion are connected to each other to form an L-shaped structure, the base portion is arranged on one side of the claw hole and on one of the pair of wall portions, so that the claw portion passes through the claw hole next to the base portion, and the limiting portion is arranged between one of the pair of wall portions and the loading portion, or between the claw portion and the base portion.

[0016] In an embodiment of the present invention, the carrying portion and the claw portion are connected to each other to form a T-shaped structure, a pair of the base portions are arranged on opposite sides of the claw hole and on both of the pair of wall portions, so that the claw portion passes through the claw hole between the pair of the base portions, and the limiting portion is arranged between one of the pair of wall portions and the carrying portion, or between the claw portion and one of the base portions.

[0017] In an embodiment of the present invention, the claw portion of the locking claw is offset relative to the center line of the slider body and can be inserted through one of a pair of fastener element rows in the fastener element channel.

[0018] Based on the above, in the slider of the present invention, one of the base portion of the slider body and the carrier portion of the locking claw is provided with a limiting portion for limiting the carrier portion in the width direction, and in the receiving space formed by a pair of wall portions of the slider body, a gap portion for the carrier portion to move is provided above the base portion, and the carrier portion and the inner wall of one of the pair of wall portions are spaced apart to form the gap portion. In this way, when a pair of chain teeth of the zipper chain pass through the chain tooth channel of the slider body, the claw portion of the locking claw can be inserted into the chain tooth row on one side to lock, and the carrier portion can be limited by the limiting portion to suppress displacement in the width direction, thereby ensuring the locking strength of the locking claw. Correspondingly, when the insertion rod of the zipper chain is inserted into the slider body and passes through the chain tooth channel, the claw portion of the locking claw can be pushed by the insertion rod and rotated to pass over the limiting portion and move to the gap portion, thereby avoiding the locking claw from interfering with the insertion of the insertion rod. Accordingly, the slider of the present invention can take into account both the locking strength of the locking claw and the insertion effect of the insertion rod, thereby having good operability.

Figures 1 to 8 The specific structure and operation method of the slider 100 according to an embodiment of the present invention are described. Fig. 9 and Fig.10 The specific structures and operation methods of the sliders 100A and 100B in other modified examples are described, but the present invention is not limited thereto and can be adjusted according to needs.

[0061] Please refer to Figures 1 to 3 In this embodiment, the slider 100 is suitable for installation on the zipper chain 50. Figure 2 As shown, the zipper chain 50 includes a pair of zipper tapes 52 extending along the length direction L, and a pair of chain element rows 54 arranged side by side at the inner side edges of the pair of zipper tapes 52 along the length direction L. In addition, the zipper chain 50 is also provided with an insert rod 56 and a seat rod 58. The insert rod 56 and the seat rod 58 are respectively arranged on the pair of zipper tapes 52 and located at the ends of the pair of chain element rows 54. The insert rod 56 and the seat rod 58 can be engaged with each other to fix the ends of the zipper chain 50. Correspondingly, as shown in FIG. Figure 1 and Figure 3 As shown, the slider 100 includes a slider body 110, a locking claw 120, and a pull tab 130. The slider body 110 is used to be installed on a Figure 2 The locking claw 120 is disposed on the slider body 110 and extends toward the inside of the slider body 110. The pull tab 130 is disposed on the slider body 110 to drive the slider body 110 to slide relative to the zipper chain 50 to open or close a pair of chain element rows 54 provided on the zipper chain 50, and can drive the locking claw 120 to move.

[0062] Thus, in this embodiment, when Figure 2 When the chain element row 54 of the zipper chain 50 shown in FIG. 1 passes through the slider body 110, as shown in FIG. Figure 4 As shown, the locking claw 120 can be inserted into the chain tooth row 54 on one side to lock the slider body 110 on the zipper chain 50 (as described later). In addition, the locking claw 120 can be unlocked while driving the slider body 110 to slide relative to the zipper chain 50 via the pull tab 130 (as described later). Figure 2When the insertion rod 56 provided at the end of the chain element row 54 of the zipper chain 50 shown in FIG. 1 passes through the slider body 110, as shown in FIG. Figure 5 and Figure 6 As shown, the locking claw 120 extending into the interior of the slider body 110 does not interfere with the plunger 56 (as described later). Figures 3 to 6 , and subsequent Figures 3 to 6 Related Figure 7 and Figure 8 The pull tab 130 and its mounting structure are omitted in order to illustrate the structure and relative relationship of the slider body 110, the locking claw 120 and the limiting portion 140. Figure 4 The fastener element row 54 on one side is omitted in order to illustrate the structure and relative relationship between the locking claw 120 and the inserted fastener element row 54. Figure 5 Part of the slider body 110 and the seat rod 58 are omitted in order to illustrate the structure and relative relationship of the insertion rod 56 and the locking claw 120 inside the slider body 110. However, the present invention does not limit the application and operation method of the slider 100 on the zipper chain 50, nor does it limit the specific structure and type of the slider 100 and the zipper chain 50 used, which can be adjusted according to needs.

[0063] Specifically, in this embodiment, if Figure 1 and Figure 3 As shown, the slider body 110 includes an upper wing plate 111 and a lower wing plate 112 disposed opposite to each other, and a guide column 113 connecting the upper wing plate 111 and the lower wing plate 112, and has a chain tooth channel 114 located between the upper wing plate 111 and the lower wing plate 112. The upper wing plate 111 and the lower wing plate 112 are, for example, plate-shaped structures with side flanges, and the guide column 113 is disposed on the front side E1 of the slider body 110 to connect the upper wing plate 111 and the lower wing plate 112, so as to open or close a pair of chain tooth rows 54 when the slider body 110 slides relative to the zipper chain 50. In addition, the tooth channel 114 between the upper wing plate 111 and the lower wing plate 112 is divided into a double channel on the front side E1 by the guide column 113 to allow the tooth row 54 that has not yet been engaged to pass through, and is formed into a single channel on the rear side E2 of the slider body 110 opposite to the guide column 113 to allow the tooth row 54 that has been engaged with each other to pass through. More specifically, the slider body 110 has a pair of wall portions 116a, 116b disposed on the upper wing plate 111 and forming a receiving space S for the locking claw 120, a claw hole 117 formed between the pair of wall portions 116a, 116b and communicating with the tooth channel 114, and a base portion 118 disposed between the pair of wall portions 116a, 116b and at least on one side of the claw hole 117 and on one of the pair of wall portions 116a, 116b to support the locking claw 120. Figure 3The illustrated embodiment is described by taking the case where the pedestal portion 118 is disposed on the left side of the claw hole 117 and on the left wall portion 116a as an example, for example, the pedestal portion 118 extends from the lower side of the left wall portion 116a into the claw hole 117 (i.e., to the right side). However, in other embodiments not shown, the pedestal portion 118 may also be disposed on the right side of the claw hole 117 and on the right wall portion 116b.

[0064] Correspondingly, in this embodiment, if Figure 1 and Figure 3 As shown, the locking claw 120 has a holding portion 122 (at the front side E1 of the slider body 110) held thereon. Figure 1 ), a loading portion 124 which is on the opposite side of the holding portion 122 and is loaded on the pedestal portion 118, and a claw portion 126 which extends downward from the loading portion 124 and passes through the claw hole 117. In this way, the holding portion 122 of the locking claw 120 is configured as a fixed end fixed on the slider body 110, and the loading portion 124 and the claw portion 126 are configured as free ends that can move in the receiving space S, so as to facilitate locking or unlocking through the pull tab 130. In addition, when the loading portion 124 is loaded on the pedestal portion 118, the claw portion 126 further extends into the claw hole 117 beside the pedestal portion 118, so that the claw portion 126 can enter the chain tooth channel 114 of the slider body 110 and lock the chain tooth row 54 on one side passing through the chain tooth channel 114. The locking means that the slider body 110 cannot slide relative to the zipper chain 50, and its specific operation means are described later. In addition, the pull tab 130 is arranged on the slider body 110. For example, the mounting ring portion 132 of the pull tab 130 is installed on the slider body 110 through the pull tab ring portion 115 and the locking claw 120 provided on the upper side of the slider body 110, so that the movement of the pull tab 130 can be linked to the locking claw 120 (as described later).

[0065] Furthermore, in this embodiment, if Figure 3 As shown, one of the base portion 118 of the slider body 110 and the mounting portion 124 of the locking claw 120 is provided with a limiting portion 140 for limiting the mounting portion 124 in the width direction W. Figure 3In the illustrated embodiment, the limiting portion 140 is disposed on a side of the base portion 118 opposite to the claw hole 117, for example, at a corner between the base portion 118 and the wall portion 116a on which the base portion 118 is disposed, and limits the displacement of the carrier portion 124 relative to the base portion 118 in the width direction W. That is, when the carrier portion 124 is placed on the base portion 118, one side (for example, the left side) of the carrier portion 124 is restrained from displacement in the width direction W by the abutment of the limiting portion 140. Preferably, the limiting portion 140 includes an inclined surface (for example, an inclination angle of 30 to 60 degrees) that is inclined downward toward the base portion 118 on which the carrier portion 124 is placed. The inclined surface may be as follows: Figure 3 The plane shown may also be a protruding arc surface. In other embodiments not shown, the limiting portion 140 may also be a tiny protrusion (for example, a height of between 0.05 mm and 0.1 mm) disposed on the surface of the pedestal portion 118 and close to the wall portion 116a (i.e., the side opposite to the claw hole 117). The tiny protrusion may be a point-shaped or block-shaped protrusion, or a strip-shaped rib, etc. The present invention does not limit the specific structure of the limiting portion 140 disposed on the pedestal portion 118, which may be adjusted as required. Furthermore, the present invention does not limit the setting position of the limiting portion 140. In the subsequent first variant, the limiting portion may also be disposed on the carrier portion of the locking claw and between the claw portion and the pedestal portion (as described later), as long as the limiting portion can limit the carrier portion in the width direction, which may be adjusted as required.

[0066] Furthermore, in this embodiment, if Figure 3 As shown, in the storage space S formed by the pair of wall portions 116a and 116b, a gap portion 119 is provided above the base portion 118 for the loading portion 124 to move, and the loading portion 124 is spaced apart from the inner wall of one of the pair of wall portions 116a and 116b to form the gap portion 119. That is, when the loading portion 124 is placed on the base portion 118, it does not contact the side wall 116a of the pair of wall portions 116a and 116b where the base portion 118 is provided, but the gap portion 119 is maintained. Figure 3 In the illustrated embodiment, the gap portion 119 is formed by the inner wall of the wall portion 116a on the left side being spaced apart from the carrier portion 124. Preferably, the gap portion 119 is located above the limit portion 140 in the vertical direction (i.e., the thickness direction T of the slider body 110). In this way, the gap portion 119 can serve as a moving space for the carrier portion 124 of the locking claw 120 after overcoming the limit of the limit portion 140 (as described later). However, the present invention does not limit the specific structure of the gap portion 119, which can be adjusted according to needs.

[0067] In addition, in the present embodiment, the claw portion 126 of the locking claw 120 is offset relative to the center line C of the slider body 110 (for example, it is offset to the right side), and can be inserted through one of the pair of tooth rows 54 in the tooth channel 114 (for example, the right tooth row 54). As an example, the carrier portion 124 and the claw portion 126 are connected to each other to form an L-shaped structure, for example, the carrier portion 124 extends to the left relative to the claw portion 126 so that the claw portion 126 is offset to the right side. In addition, the base portion 118 is disposed on one side of the claw hole 117 (for example, the left side) and on one of the pair of wall portions 116a, 116b (for example, the left wall portion 116a), so that the claw portion 126 passes through the claw hole 117 next to the base portion 118, and the stopper 140 is disposed between one of the pair of wall portions 116a, 116b (for example, the left wall portion 116a) and the carrier portion 124. In this way, when the carrying portion 124 protruding to the left relative to the claw portion 126 is placed on the base portion 118 arranged on the left side of the accommodating space S, one side (for example, the left side) of the carrying portion 124 is limited by the abutment of the limiting portion 140, thereby suppressing the displacement of the carrying portion 124 relative to the base portion 118 on the left side in the width direction W (that is, suppressing the displacement of the carrying portion 124 to the left in the width direction W).

[0068] However, in other embodiments not shown, the claw portion 126 of the locking claw 120 may be disposed on the left side relative to the center line C of the slider body 110 and may be inserted through the left side of the fastener element row 54 in the fastener element passage 114. In this case, the carrier portion 124 extends to the right side relative to the claw portion 126 so that the claw portion 126 is disposed on the left side, the pedestal portion 118 is disposed on the right side of the claw hole 117 and on the right side wall portion 116b so that the claw portion 126 passes through the claw hole 117 next to the pedestal portion 118, and the limiting portion 140 is disposed between the right side wall portion 116b and the carrier portion 124 (i.e., the right side of the carrier portion 124 is limited by the abutment of the limiting portion 140), thereby suppressing the displacement of the carrier portion 124 to the right side in the width direction W. In other words, the positions of the claw portion 126, the carrier portion 124, the pedestal portion 118, etc. may be adjusted accordingly as required. Furthermore, the present invention does not limit the shape of the locking claw 120. In the subsequent second variation, the locking claw can also be set to a T-shape (as described later). As long as the locking claw has a loading portion placed on the base portion and a claw portion extending downward and passing through the claw hole, it can be adjusted according to needs.

[0069] It can be seen that in this embodiment, if Figure 2 As shown, in the pull head 100 (such as Figure 2 When the zipper chain 50 is installed, as shown in the dotted line Figure 1 and Figure 3The slider body 110 shown slides relative to the zipper chain 50 by the pull tab 130, thereby opening or closing the chain element row 54. For example, the slider body 110 moves upward by the pull tab 130 to close the chain element row 54, and moves downward by the pull tab 130 to open the chain element row 54 (but not limited to this). In this process, Figure 4 As shown, since the claw portion 126 of the locking claw 120 is offset relative to the center line C of the slider body 110 (for example, it is set to the right side), when a pair of chain tooth rows 54 of the zipper chain 50 pass through the chain tooth channel 114 of the slider body 110, the claw portion 126 of the locking claw 120 can be inserted into the chain tooth row 54 on one side of the pair of chain tooth rows 54 in the chain tooth channel 114 (for example, the chain tooth row 54 on the right side) (for example, inserted between two chain teeth in the chain tooth row 54) to lock, so that the slider body 110 cannot slide relative to the zipper chain 50, and the loading portion 124 can be limited by the limiting portion 140 to suppress the displacement in the width direction W, thereby ensuring the locking strength of the locking claw 120.

[0070] In addition, in this embodiment, since the slider 100 is further provided with a pull tab 130 that is linked to the locking claw 120, Figure 4 The locking claw 120 in the locked state can be unlocked by the pull tab 130. For example, when the pull tab 130 is pulled up, the pull tab 130 drives the locking claw 120 to move upward and leave the chain tooth row 54, so that the slider body 110 can slide on the zipper chain 50. During the sliding process of the slider body 110, the locking claw 120 remains unlocked by the pull tab 130 to maintain a smooth sliding operation. At this time, the claw portion 126 of the locking claw 120 leaves the chain tooth row 54, but it is preferred that the loading portion 124 is still located in the receiving space S and the claw portion 126 is still located in the chain tooth channel 114, so as to shorten the moving distance of the locking claw 120 to maintain stability (but not limited to this). When the pull tab 130 is released (for example, the pull tab 130 is reset via an elastic member not shown), the pull tab 130 drives the locking claw 120 to move downward, so that the mounting portion 124 of the locking claw 120 is mounted on the pedestal portion 118 and the claw portion 126 is inserted into the chain element row 54 on one side of the zipper chain 50 to lock (i.e., Figure 4 In this way, not only can the slider body 110 be locked on the zipper chain 50 via the locking claw 120 with a good locking effect, but the locking claw 120 can also be released when the slider body 110 is driven to slide relative to the zipper chain 50 by the pull tab 130.

[0071] Furthermore, in this embodiment, when the slider 100 (such as Figure 2When the slider 100 (shown by the dotted line) moves to the end of the zipper chain 50, the pull tab 130 can be used to drive the slider body 110 through the end insertion rod 56 and the seat rod 58, or the slider body 110 can be driven by hand to pass through the end insertion rod 56 and the seat rod 58 (preferably the latter). At this time, even if the claw 126 is located in the chain tooth channel 114, it will not be inserted between the last chain tooth and the insertion rod 56 or the seat rod 58 to lock. That is, when the slider 100 (as shown in FIG. Figure 2 When the slider 110 moves to the end of the zipper chain 50 (shown by the dotted line), the slider body 110 will not be locked regardless of whether the pull tab 130 is pulled. Accordingly, the insertion rod 56 and the seat rod 58 are inserted into the slider body 110 from bottom to top. Figure 5 and Figure 6 As shown in FIG. 1 , since the claw portion 126 of the locking claw 120 is offset relative to the center line C of the slider body 110 (for example, offset to the right), when the seat bar 58 on the left side of the zipper chain 50 is inserted into the slider body 110 and passes through the chain tooth channel 114 (at Figure 5 The seat bar 58 is omitted in the figure. Figure 6 The seat rod 58 does not contact the claw portion 126 of the locking claw 120 and can smoothly pass through the chain tooth channel 114. When the insertion rod 56 provided on the right side of the zipper chain 50 is inserted into the slider body 110 and passes through the chain tooth channel 114 (in Figure 5 and Figure 6 The plunger 56 contacts the claw portion 126 of the locking claw 120 , but can also pass through the tooth channel 114 smoothly.

[0072] Furthermore, in this embodiment, if Figure 5 and Figure 6 As shown, since a gap 119 is provided above the base portion 118 for the loading portion 124 to move, when the insert rod 56 of the zipper chain 50 is inserted into the slider body 110 and passes through the chain tooth channel 114, as shown in FIG. Figures 6 to 8As shown in the operation diagram of , the claw portion 126 of the locking claw 120 can be pushed by the plunger 56 to rotate (for example, the plunger 56 on the right side pushes the claw portion 126 disposed on the right side to rotate to the left and upward in a clockwise direction) to pass the limiting portion 140 and move to the upper gap portion 119 (for example, the claw portion 126 moves upward along the surface of the limiting portion 140). In other words, the limiting portion 140 limits the carrier portion 124 in the width direction W (for example, limits the displacement of the carrier portion 124 to the left), but because the rotation of the claw portion 126 is accompanied by a moving component moving upward, it can overcome the limit of the limiting portion 140 and move to the gap portion 119 disposed above the pedestal portion 118, thereby causing the claw portion 126 to move in the direction of the center line C and make way for the chain tooth channel 114 for the plunger 56 to pass through. In summary, with all the structural features described above, the slider 100 of this embodiment can take into account both the locking strength of the locking claw 120 and the insertion effect of the inserting rod 56 , thereby having good operability.

[0073] However, the above-mentioned method of limiting the position of the placing portion 124 in the width direction W by the limiting portion 140 (such as Figure 4 ), the way in which the pull tab 130 unlocks the locking claw 120, and the way in which the plunger 56 pushes the claw portion 126 (as shown in FIG. Figures 6 to 8 (shown) is only one example. For example, in other embodiments not shown, when the claw portion 126 of the locking claw 120 is arranged on the left side relative to the center line C of the slider body 110, the claw portion 126 can be inserted through the left side of the chain tooth row 54 of the chain tooth channel 114 to lock, and the limiting portion 140 is arranged on the right side to prevent the displacement of the carrier portion 124 to the right side in the width direction W. In addition, the insertion rod 56 can be arranged at the end of the chain tooth row 54 on the left side and pass through the chain tooth channel 114 on the left side, and the claw portion 126 arranged on the left side of the locking claw 120 can be pushed by the insertion rod 56 on the left side and rotated to pass over the limiting portion 140 arranged on the right side and move to the upper gap portion 119. In this way, according to the changes in the components such as the slider body 110, the locking claw 120, and the limiting portion 140 as described above, the limiting method of the limiting portion 140, the unlocking method of the pull tab 130, and the operation method of the insertion rod 56 can be adjusted according to needs, and the present invention is not limited thereto.

[0074] Although the variations of the slider body 110, the locking claw 120, and the limiting portion 140 in the slider 100 have been described so far, other variations are also included. Figure 3 In the illustrated embodiment, the base portion 118 of the slider body 110 of the slider 100 is provided with a limiting portion 140 for limiting the position of the mounting portion 124 in the width direction W. Fig. 9In the first modification shown, the placement portion 124A of the locking claw 120A of the slider 100A is provided with a stopper 140A for limiting the placement portion 124A in the width direction W. That is, the setting position of the stopper 140A is adjusted.

[0075] Specifically, in Fig. 9 In the first variation shown, the carrier portion 124A of the locking claw 120A of the slider 100A is provided with a limiting portion 140A for limiting the carrier portion 124A in the width direction W, wherein the limiting portion 140A is arranged on one side of the carrier portion 124A adjacent to the claw portion 126A, for example, at the corner between the carrier portion 124A and the claw portion 126A, and limits the displacement of the carrier portion 124A relative to the pedestal portion 118A in the width direction W. That is, when the carrier portion 124A is placed on the pedestal portion 118A, one side (for example, the left side) of the carrier portion 124A is restrained from unexpected displacement of the carrier portion 124A in the width direction W by the abutment of the limiting portion 140A. Preferably, the limiting portion 140A includes an inclined surface (for example, an inclined angle of 30 to 60 degrees) that is inclined downward from the carrier portion 124A toward the claw portion 126A. The inclined surface may be Fig. 9 The present invention does not limit the specific structure of the position-limiting portion 140A disposed on the mounting portion 124A, and it can be adjusted according to needs.

[0076] Furthermore, in Fig. 9 In the first variant shown, the slider body 110A of the slider 100A is also provided with a gap portion 119A located above the base portion 118A in the receiving space S and for the carrier portion 124A to move. Preferably, the gap portion 119A is located above the limit portion 140A in the up-down direction (i.e., the thickness direction T of the slider body 110A). In this way, the gap portion 119A can serve as a moving space for the carrier portion 124A of the locking claw 120A after overcoming the limit of the limit portion 140A. In addition, in Fig. 9In the first variation shown, the claw portion 126A of the locking claw 120A is offset relative to the center line C of the slider body 110A (for example, it is set to the right side), and can be inserted through one of the pair of tooth rows 54 in the tooth channel 114 (for example, the right tooth row 54). As an example, the carrier portion 124A and the claw portion 126A are connected to each other to form an L-shaped structure, the base portion 118A is set on one side of the claw hole 117A (for example, the left side) and on one of the pair of wall portions 116a, 116b (for example, the left wall portion 116a), so that the claw portion 126A passes through the claw hole 117A next to the base portion 118A, and the limit portion 140A is set between the claw portion 126A and the base portion 118A. In this way, when the carrying portion 124A protruding to the left relative to the claw portion 126A is placed on the base portion 118A arranged on the left side of the accommodating space S, one side (for example, the left side) of the carrying portion 124A is limited by the abutment of the limiting portion 140A, thereby suppressing the displacement of the carrying portion 124A to the left in the width direction W.

[0077] From this we can see that Fig. 9 In the first variation shown, the slider 100A may also have Figure 1 The three-dimensional structure of the slider 100 shown in FIG. 1 (i.e., including the slider body 110A, the locking claw 120A, the pull tab 130, and the limiting portion 140A) is installed on a Figure 2 On the zipper chain 50 shown, the main difference between the slider 100A and the slider 100 mentioned above is that the setting position of the limit portion 140A is different from the setting position of the limit portion 140 mentioned above, and the slider body 110A and the locking claw 120A are adjusted according to the setting position of the limit portion 140A. However, according to the specific structure and setting position of the slider body 110A, the locking claw 120A, and the limit portion 140A described above, the slider 100A can also have the same operation method as the slider 100 mentioned above. That is, when the slider 100A is installed on the zipper chain 50 (such as Figure 2 In the state shown in FIG. 1 , the slider body 110A is driven by the pull tab 130 to slide relative to the zipper chain 50, thereby opening or closing the chain element row 54. In this process, when a pair of chain element rows 54 of the zipper chain 50 pass through the chain element channel 114 of the slider body 110A, the claw portion 126A of the locking claw 120A can be as shown in FIG. Figure 4The pawl 126 shown in the figure is inserted into the tooth row 54 on one side (for example, the tooth row 54 on the right side) of the tooth channel 114 to lock it, and the carrier portion 124A can be limited by the limiting portion 140A to suppress the displacement in the width direction W, thereby ensuring the locking strength of the locking pawl 120A. Subsequently, the locking pawl 120A in the locked state can be unlocked by the pull tab 130. In this way, not only can the slider body 110A be locked on the zipper chain 50 by the locking pawl 120A with a good locking effect, but the locking pawl 120A can also be unlocked at the same time when the pull tab 130 is used to drive the slider body 110A to slide relative to the zipper chain 50.

[0078] Furthermore, in Fig. 9 In the first variation shown, during the sliding process of the slider body 110A, the locking claw 120A remains unlocked by the pull tab 130. Figure 5 and Figure 6 When the plunger 56 of the zipper chain 50 shown is inserted into the slider body 110A and passes through the tooth passage 114, the claw portion 126A of the locking claw 120A can be Figures 6 to 8 As shown in the operation diagram of the claw portion 126, it is pushed by the insertion rod 56 and rotates to pass the limiting portion 140A and move to the upper gap portion 119A. That is to say, the limiting portion 140A limits the carrier portion 124A in the width direction W (for example, limiting the displacement of the carrier portion 124A to the left), but because the rotation of the claw portion 126A is accompanied by a moving component moving upward, it can overcome the limitation of the limiting portion 140A and move to the gap portion 119A provided above the base portion 118A, thereby causing the claw portion 126A to move in the direction of the center line C and make way for the chain tooth channel 114 for the insertion rod 56 to pass through. It can be seen from this that the present invention does not limit the setting positions of the limiting portions 140 and 140A, which can be adjusted as needed. In summary, the characteristics of all the structures described above, the slider 100A of this embodiment can also take into account the locking strength of the locking claw 120A and the insertion effect of the insertion rod 56, thereby having good operability.

[0079] In addition, Figure 3 In the illustrated embodiment, the carrier portion 124 and the claw portion 126 of the locking claw 120 are connected to each other to form an L-shaped structure, wherein the base portion 118 is disposed on one side (e.g., the left side) of the claw hole 117 and on one of the pair of wall portions 116a, 116b (e.g., the left wall portion 116a), so that the claw portion 126 passes through the claw hole 117 next to the base portion 118, and the stop portion 140 is disposed between one of the pair of wall portions 116a, 116b (e.g., the left wall portion 116a) and the carrier portion 124. Fig. 9In the first modified example shown, the receiving portion 124A and the claw portion 126A of the locking claw 120A are connected to each other to form an L-shaped structure, and the stopper 140A is provided between the claw portion 126A and the base portion 118A. Fig.10 In the second variant shown, the carrying portion 124B and the claw portion 126B of the locking claw 120B of the slider 100B are connected to each other to form a T-structure, wherein a pair of seating portions 118B are arranged on opposite sides of the claw hole 117B and on both of a pair of wall portions 116a, 116b, so that the claw portion 126B passes through the claw hole 117B between the pair of seating portions 118B, and the limiting portion 140B is arranged between one of the pair of wall portions 116a, 116b (for example, the left wall portion 116a) and the carrying portion 124B.

[0080] Specifically, in Fig.10 In the second modified example shown, the claw portion 126B of the locking claw 120B is offset relative to the center line C of the slider body 110B (for example, it is set to the right side), and can be inserted into one of the pair of tooth rows 54 (for example, the right tooth row 54) through the tooth channel 114. As an example, the carrier portion 124B and the claw portion 126B of the locking claw 120B of the slider 100B are connected to each other to form a T-shaped structure, for example, a pair of carrier portions 124B extend to the left and right sides respectively relative to the claw portion 126B, and the dimension of the left carrier portion 124B in the width direction W is greater than the dimension of the right carrier portion 124B in the width direction W, so that the claw portion 126B is set to the right side. Furthermore, a pair of pedestal portions 118B are provided on the slider body 110B in response to the pair of mounting portions 124B, and are located on opposite sides of the claw hole 117B and on both of the pair of wall portions 116a, 116b, so that the claw portion 126B passes through the claw hole 117B between the pair of pedestal portions 118B. In addition, the stopper portion 140B is provided between one of the pair of wall portions 116a, 116b (for example, the left wall portion 116a) and the mounting portion 124B. That is, although a pair of mounting portions 124B and a pair of pedestal portions 118B are provided, it is preferred that a stopper portion 140B is provided on one of the sides (but the present invention does not exclude the practice of providing a pair of stopper portions 140B). In this way, when a pair of loading portions 124B are loaded on a pair of pedestal portions 118B arranged on opposite sides of the accommodating space S, one side (for example, the left side) of the loading portion 124B is limited by the abutment of the limiting portion 140B, thereby suppressing the displacement of the loading portion 124B to the left in the width direction W.

[0081] Furthermore, in Fig.10In the second variant shown, the slider body 110B of the slider 100B is also provided with a gap portion 119B located above the base portion 118B in the receiving space S and for the carrier portion 124B to move. Preferably, the gap portion 119B is located above the limit portion 140B in the up-down direction (i.e., the thickness direction T of the slider body 110B). In this way, the gap portion 119B can serve as a moving space for the carrier portion 124B of the locking claw 120B after overcoming the limit of the limit portion 140B. In addition, in Fig.10 In the second variant shown, the limit portion 140B is arranged between one of the pair of wall portions 116a, 116b (for example, the left wall portion 116a) and the loading portion 124B, and limits the displacement of the loading portion 124B relative to the base portion 118B in the width direction W, but in other embodiments not shown, the limit portion 140B may also be arranged on one side of the loading portion 124B adjacent to the claw portion 126B (which may be an inclined surface, etc.), and arranged between the claw portion 126B and one of the base portions 118B.

[0082] From this we can see that Fig.10 In the second variation shown, the slider 100B may also have Figure 1 The three-dimensional structure of the slider 100 shown in FIG. 1 (i.e., including the slider body 110B, the locking claw 120B, the pull tab 130, and the limiting portion 140B) is installed in a Figure 2 On the zipper chain 50 shown in the figure, the main difference between the slider 100B and the slider 100 mentioned above is that the specific structure of the slider body 110B and the locking claw 120B is different from the specific structure of the slider body 110 and the locking claw 120 mentioned above. However, according to the specific structure and setting position of the slider body 110B, the locking claw 120B, and the limit portion 140B described above, the slider 100B can also have the same operation method as the slider 100 mentioned above. That is, when the slider 100B is installed on the zipper chain 50 (such as Figure 2 In the state shown in FIG. 1 , the slider body 110B is driven by the pull tab 130 to slide relative to the zipper chain 50, thereby opening or closing the chain element row 54. In this process, when a pair of chain element rows 54 of the zipper chain 50 pass through the chain element channel 114 of the slider body 110B, the claw portion 126B of the locking claw 120B can be as shown in FIG. Figure 4The pawl 126 shown in the figure is inserted into the tooth row 54 on one side (for example, the tooth row 54 on the right side) of the tooth channel 114 to lock it, and the carrier portion 124B can be limited by the limiting portion 140B to suppress the displacement in the width direction W, thereby ensuring the locking strength of the locking pawl 120B. Subsequently, the locking pawl 120B in the locked state can be unlocked by the pull tab 130. In this way, not only can the slider body 110B be locked on the zipper chain 50 by the locking pawl 120B with a good locking effect, but the locking pawl 120B can also be unlocked at the same time when the pull tab 130 is used to drive the slider body 110B to slide relative to the zipper chain 50.

[0083] Furthermore, in Fig.10 In the second variation shown, during the sliding process of the slider body 110B, the locking claw 120B remains unlocked by the pull tab 130. Figure 5 and Figure 6 When the plunger 56 of the zipper chain 50 shown in the figure is inserted into the slider body 110B and passes through the tooth passage 114, the claw portion 126B of the locking claw 120B can be as shown in FIG. Figures 6 to 8 As shown in the operation diagram of the claw portion 126, the claw portion 126 is pushed by the plunger 56 and rotates to pass the limiting portion 140B and move to the upper gap portion 119B. That is to say, the limiting portion 140B limits the carrier portion 124B in the width direction W (for example, limits the displacement of the carrier portion 124B to the left), but because the rotation of the claw portion 126B is accompanied by a moving component moving upward, it can overcome the limiting of the limiting portion 140B and move to the gap portion 119B provided above the pedestal portion 118B, thereby causing the claw portion 126B to move in the direction of the center line C and make way for the chain tooth channel 114 for the plunger 56 to pass through. It can be seen from this that the present invention does not limit the specific structure of the slider body 110 and 110B, the locking claw 120 and 120B, and it can be adjusted as needed. In view of all the structural features described above, the slider 100B of this embodiment can also take into account both the locking strength of the locking claw 120B and the insertion effect of the insert rod 56 , thereby having good operability.

[0084] In summary, in the slider of the present invention, one of the base portion of the slider body and the carrier portion of the locking claw is provided with a limiting portion for limiting the carrier portion in the width direction, and in the receiving space formed by a pair of wall portions of the slider body, a gap portion for the carrier portion to move is provided above the base portion, and the carrier portion and the inner wall of one of the pair of wall portions are spaced apart to form the gap portion. Preferably, the claw portion of the locking claw is offset relative to the center line of the slider body. In this way, when a pair of chain teeth of the zipper chain pass through the chain tooth channel of the slider body, the claw portion of the locking claw can be inserted into the chain teeth on one side to lock, and the carrier portion can be limited by the limiting portion to suppress the displacement in the width direction, thereby ensuring the locking strength of the locking claw. Correspondingly, when the insertion rod of the zipper chain is inserted into the slider body and passes through the chain tooth channel, the claw portion of the locking claw can be pushed by the insertion rod and rotated to move to the gap portion over the limiting portion, thereby avoiding the locking claw from interfering with the insertion of the insertion rod. Accordingly, the slider of the present invention can take into account both the locking strength of the locking claw and the insertion effect of the insertion rod, thereby having good operability.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements 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.
