Description

[Technical Field]

[0001] The present invention relates to the field of fastener technology, and more particularly to sliders. [Background technology]

[0002] A typical fastener typically includes a strip of fastener tape, a pair of fastener chains consisting of multiple element columns arranged on the fastener tape, and a slider attached to the fastener chain that slides to open and close the elements. A tab pull can also be attached to the slider, if necessary. A lock pin is also provided on the slider body of the slider, and the slider is locked to the fastener chain via the lock pin. For example, the lock pin extends downward through a claw hole in the slider body and is inserted into the element column or fastener tape on which the fastener chain is attached. The locking method can vary depending on the type of fastener, slider, or lock pin. The insertion of the lock pin can also be linked to the pull. For example, when the pull tab is pulled to drive the slider, the pull simultaneously drives the lock pin to unlock. The unlocking method can vary depending on the type of fastener, slider, or lock pin.

[0003] Furthermore, in the prior art, the fastener chain is further provided with a separable pin and a retainer pin. The separable pin and the retainer pin are provided on a pair of fastener tapes, respectively, and are located at the ends of a pair of element rows. The separable pin and the retainer pin can also be fitted together to secure the ends of the fastener chain. In this manner, with the slider attached to the fastener chain, the slider slides relative to the fastener chain to open and close the element rows. When the slider moves to the end of the fastener chain, the separable pin and the retainer pin are inserted from bottom to top into the slider body and pass through the element passages, respectively. At this time, if a lock pin is installed on one side of the slider body so that the lock pin can be inserted into the element row on one side to avoid a decrease in locking strength, the lock pin will interfere with the insertion of the separable pin. On the other hand, if the lock pin is installed in the center of the slider body to avoid the lock pin interfering with the insertion of the separable pin, the lock pin will only be inserted between the pair of element rows, resulting in a decrease in locking strength.

[0005] As described above, improvements are required in the structure of the slider body and the lock pin of the slider. [Means for solving the problem]

[0006] The present invention provides a slider that combines the locking strength of a lock pin and the insertion effect of an insert pin, and has good operability.

[0007] The present invention provides a slider suitable for attachment to a fastener chain, comprising: a slider body including upper and lower blades arranged opposite to each other, and guide posts connecting the upper and lower blades, and having an element passage located between the upper and lower blades; a lock pin arranged on the slider body; and a pull tab arranged on the slider body for driving and moving the lock pin. The slider body has a pair of wall portions arranged on the upper blade and forming an accommodating space for the lock pin, a claw hole formed between the pair of wall portions and communicating with the element passage, and a slider body having at least one locking pin between the pair of wall portions. a base portion on which the locking pin is placed, the base portion being installed on one side of the claw hole and on one side of the pair of wall portions; the locking pin having a holding portion held on the front side of the slider body, a placing portion opposite the holding portion and placed on the base portion, and a claw portion extending downward from the placing portion and passing through the claw hole; one of the base portion and the placing portion is provided with a position regulating portion that regulates the position of the placing portion in the width direction; and a gap portion in which the placing portion moves is provided above the base portion in the storage space, and the placing portion and an inner wall on one side of the pair of wall portions are installed at a distance to form the gap portion.

[0008] In an embodiment of the present invention, the gap portion is located above the position restriction portion in the up-down direction.

[0009] In an embodiment of the present invention, the position regulating portion is installed on the base portion on the opposite side to the nail hole, and regulates displacement of the placing portion relative to the base portion in the width direction.

[0010] In an embodiment of the present invention, the position restriction portion includes an inclined surface that slopes downward toward the base portion on which the placement portion is placed.

[0011] In an embodiment of the present invention, the position restricting portion is installed on the placement portion on a side adjacent to the claw portion, and restricts displacement of the placement portion relative to the base portion in the width direction.

[0012] In an embodiment of the present invention, the position restriction portion includes an inclined surface that slopes downward from the placement portion toward the claw portion.

[0013] In an embodiment of the present invention, the placement portion and the claw portion are connected to each other to form an L-shaped structure, the base portion is installed on one side of the claw hole and on one side of the pair of wall portions, the claw portion is passed through the claw hole near the base portion, and the position control portion is installed between one side of the pair of wall portions and the placement portion, or between the claw portion and the base portion.

[0014] In an embodiment of the present invention, the placement portion and the claw portion are connected to each other to form a T-shaped structure, the base portion is installed as a pair of base portions on opposite sides of the claw hole and on both of the pair of wall portions, the claw portion is passed through the claw hole between the pair of base portions, and the position control portion is installed between one side of the pair of wall portions and the placement portion, or between the claw portion and one of the base portions.

[0015] In an embodiment of the present invention, the claw portion of the lock pin is installed offset with respect to the center line of the slider body and is insertable into one of a pair of element rows passing through the element passage.

[0016] Based on the above, in the slider of the present invention, one of the base portion of the slider body and the mounting portion of the lock pin is provided with a position restricting portion that restricts the position of the mounting portion in the width direction, and a gap portion through which the mounting portion moves is provided above the base portion in an accommodation space formed by a pair of wall portions of the slider body, and the mounting portion and one of the inner walls of the pair of wall portions are installed at a distance from each other to form the gap. In this way, when a pair of element rows of the fastener chain pass through the element passage of the slider body, the claw portion of the lock pin can be inserted into one of the element rows on one side to lock them, and the position restriction of the mounting portion prevents the mounting portion from moving in the width direction, thereby ensuring the lock strength of the lock pin. Correspondingly, when the insert pin of the fastener chain is inserted into the slider body and passes through the element passage, the claw portion of the lock pin can rotate under the pressure of the insert pin, and the mounting portion moves toward the gap (for example, past the position restricting portion), thereby preventing the lock pin from interfering with the insertion of the insert pin. Therefore, the slider of the present invention has both the locking strength of the lock pin and the insertion effect of the insert pin, and has good operability. [Brief explanation of the drawings]

[0018] In order to make the above features and advantages of the present invention clearer and easier to understand, the following embodiments will be described in detail in combination with the drawings.

In the following, the specific configuration and operation method of the slider 100 in one embodiment of the present invention will be described using Figures 1 to 8, and the specific configuration and operation method of the slider 100A and slider 100B in other modified examples will be described using Figures 9 and 10, but the present invention is not limited to this and can be adjusted as necessary.

[0020] 1 to 3, in this embodiment, a slider 100 is suitable for attachment to a fastener chain 50. As shown in FIG. 2, the fastener chain 50 includes a pair of fastener tapes 52 extending along the longitudinal direction L and a pair of element rows 54 arranged side by side on the inner edges of the pair of fastener tapes 52 extending along the longitudinal direction L. The fastener chain 50 is further provided with an insert pin 56 and a box pin 58. The insert pin 56 and the box pin 58 are respectively arranged on the pair of fastener tapes 52 and positioned at the ends of the pair of element rows 54. The insert pin 56 and the box pin 58 can be fitted into each other to fix the ends of the fastener chain 50. Correspondingly, as shown in FIGS. 1 and 3, the slider 100 includes a slider body 110, a lock pin 120, and a pull tab 130. The slider body 110 is used for attachment to the fastener chain 50 as shown in FIG. 2. The lock pin 120 is installed in the slider body 110 and extends toward the inside of the slider body 110. The pull tab 130 is installed in the slider body 110 to drive the slider body 110 to slide relative to the fastener chain 50, to open and close a pair of element rows 54 provided on the fastener chain 50, and to drive and move the lock pin 120.

[0021] As described above, in this embodiment, when the element row 54 of the fastener chain 50 passes through the slider body 110 as shown in FIG. 2, the lock pin 120 is inserted into one of the element rows 54 as shown in FIG. 4, thereby locking the slider body 110 to the fastener chain 50 (described later). The lock pin 120 drives the slider body 110 via the pull tab 130 to slide it relative to the fastener chain 50 and simultaneously releases the lock (described later). Furthermore, when the insert pin 56 provided at the end of the element row 54 of the fastener chain 50 passes through the slider body 110 as shown in FIG. 2, the lock pin 120 extending toward the inside of the slider body 110 does not interfere with the insert pin 56 as shown in FIGS. 5 and 6 (described later). Here, in FIGS. 3 to 6 and in FIGS. 7 and 8 related to the following FIGS. 3 to 6, the pull tab 130 and its mounting configuration are omitted to make it easier to show the configurations and relative relationships of the slider body 110, the lock pin 120, and the position restricting portion 140. 4, one of the element rows 54 is omitted to make it easier to show the configuration and relative relationship between the lock pin 120 and the inserted element row 54. In FIG. 5, part of the slider body 110 and the box pin 58 are omitted to make it easier to show the configuration and relative relationship between the insert pin 56 and the lock pin 120 inside the slider body 110. However, the present invention does not limit the application or operating means of the slider 100 in the fastener chain 50, nor does it limit the specific structure and type of the slider 100 and the fastener chain 50 to be applied, and these can be adjusted as needed.

[0022] 1 and 3, the slider body 110 includes an upper blade 111 and a lower blade 112 that are disposed opposite each other, and a guide post 113 that connects the upper blade 111 and the lower blade 112, and has an element passage 114 located between the upper blade 111 and the lower blade 112. Here, the upper blade 111 and the lower blade 112 are, for example, plate-like structures with side flanges, and the guide post 113 is installed on the front side E1 of the slider body 110 and connects the upper blade 111 and the lower blade 112, and is used to open and close the pair of element rows 54 when the slider body 110 slides relative to the fastener chain 50. Furthermore, the element passage 114 between the upper blade 111 and the lower blade 112 is divided into two passages on the front side E1 by a guide pillar 113, through which the not yet engaged element rows 54 pass, and also forms a single passage on the rear side E2 opposite the guide pillar 113 of the slider body 110, through which the engaged element rows 54 pass. Furthermore, the slider body 110 has a pair of walls 116a, 116b that are provided on the upper blade 111 and form an accommodating space S for the lock pin 120, a claw hole 117 that is formed between the pair of walls 116a, 116b and communicates with the element passage 114, and a base 118 that is installed between the pair of walls 116a, 116b on at least one side of the claw hole 117 and one side of the pair of walls 116a, 116b, on which the lock pin 120 is placed. 3 is described by taking as an example the case where the seat 118 is installed on the left side of the nail hole 117 and on the left wall 116a, and the seat 118 is configured to extend from the lower side of the left wall 116a toward the nail hole 117 (i.e., to the right). However, in other embodiments not shown, the seat 118 may be installed on the right side of the nail hole 117 and on the right wall 116b.

[0023] 1 and 3, in this embodiment, the lock pin 120 has a holding portion 122 (marked in FIG. 1) that is held on the front side E1 of the slider body 110, a mounting portion 124 that is opposite the holding portion 122 and is placed on the base portion 118, and a claw portion 126 that extends downward from the mounting portion 124 and passes through the claw hole 117. In this way, the holding portion 122 of the lock pin 120 is configured as a fixed end that is fixed to the slider body 110, and the mounting portion 124 and the claw portion 126 are configured as free ends that are movable into the accommodation space S, and the locking or unlocking is performed by operating the pull tab 130. Furthermore, with the mounting portion 124 placed on the base portion 118, the claw portion 126 further extends into the claw hole 117 near the base portion 118, whereby the claw portion 126 enters the element passage 114 of the slider body 110 and can lock the element row 54 on one side passing through the element passage 114. The locking means that the slider body 110 cannot slide relative to the fastener chain 50, and specific operating means for this will be described later. The pull tab 130 is installed on the slider body 110, and for example, the attachment ring portion 132 of the pull tab 130 is attached to the slider body 110 via the pull ring portion 115 and the lock pin 120 provided on the upper side of the slider body 110, whereby movement of the pull tab 130 can be linked to the lock pin 120 (described later).

[0024] Furthermore, in this embodiment, as shown in Fig. 3, one of the base portion 118 of the slider body 110 and the mounting portion 124 of the lock pin 120 is provided with a position restricting portion 140 that restricts the position of the mounting portion 124 in the width direction W. In the embodiment shown in Fig. 3, the position restricting portion 140 is installed on the base portion 118 on the side opposite to the claw hole 117, for example, at the corner between the base portion 118 and the wall portion 116a on which the base portion 118 is provided, and restricts displacement of the mounting portion 124 relative to the base portion 118 in the width direction W. In other words, when the mounting portion 124 is placed on the base portion 118, one side (for example, the left side) of the mounting portion 124 abuts against the position restricting portion 140, suppressing displacement of the mounting portion 124 in the width direction W. Preferably, the position restricting portion 140 includes an inclined surface that slopes downward toward the base portion 118 on which the mounting portion 124 is placed (for example, the inclination angle is between 30 degrees and 60 degrees). The inclined surface may be flat as shown in FIG. 3, or may be a protruding arc surface. In another embodiment (not shown), the position restricting portion 140 is a minute protrusion (for example, having a height between 0.05 millimeters (mm) and 0.1 mm) provided on the surface of the base portion 118 near the wall portion 116a (i.e., on the opposite side from the nail holes 117). The minute protrusion may be a dot-like or block-like protrusion, or may be a strip-like convex rib. The present invention does not limit the specific structure of the position restricting portion 140 set on the base portion 118, and adjustments can be made as needed. Furthermore, the present invention does not limit the installation position of the position regulating unit 140, and in the subsequent first variant, the position regulating unit may be installed on the mounting portion of the lock pin and between the claw portion and the base portion (described later), and it is sufficient that the position regulating unit can regulate the position of the mounting portion in the width direction, and it can be adjusted as necessary.

[0025] 3, in the storage space S formed by the pair of walls 116a, 116b, a gap 119 for the placement unit 124 to move is provided above the base 118, and the placement unit 124 and one of the inner walls of the pair of walls 116a, 116b are spaced apart to form the gap 119. That is, when the placement unit 124 accommodated in the storage space S is placed on the base 118, the placement unit 124 does not come into contact with the side wall 116a of the pair of walls 116a, 116b on which the base 118 is provided, and the gap 119 is maintained. In the embodiment shown in FIG. 3, the gap 119 is formed by the placement of the placement unit 124 and the inner wall of the left wall 116a at an interval. Preferably, the gap 119 is located above the position restriction portion 140 in the vertical direction (i.e., the thickness direction T of the slider body 110). In this way, the gap 119 can serve as a movement space for the mounting portion 124 of the lock pin 120 after overcoming the position restriction of the position restriction portion 140 (described later). However, the present invention does not limit the specific structure of the gap 119, and it can be adjusted as necessary.

[0026] Furthermore, in this embodiment, the claw portion 126 of the lock pin 120 is installed offset with respect to the center line C of the slider body 110 (for example, installed offset to the right), and can be inserted into one of the pair of element rows 54 (for example, the right element row 54) passing through the element passage 114. For example, the mounting portion 124 and the claw portion 126 are connected to each other to form an L-shaped structure, and for example, the mounting portion 124 extends from the claw portion 126 toward the left, and the claw portion 126 is installed offset to the right. Furthermore, the base portion 118 is installed on one side (e.g., the left side) of the claw hole 117 and on one side (e.g., the left wall portion 116a) of the pair of wall portions 116a, 116b, so that the claw portion 126 passes through the claw hole 117 near the base portion 118, and the position restricting portion 140 is installed between one side (e.g., the left wall portion 116a) of the pair of wall portions 116a, 116b and the mounting portion 124. In this manner, when the mounting portion 124 protruding leftward relative to the claw portion 126 is placed on the base portion 118 installed on the left side of the storage space S, the position of one side (e.g., the left side) of the mounting portion 124 is restricted by abutment with the position restricting portion 140, thereby suppressing displacement of the mounting portion 124 relative to the left base portion 118 in the width direction W (i.e., suppressing displacement of the mounting portion 124 to the left in the width direction W).

[0027] However, in another embodiment (not shown), the claw portion 126 of the lock pin 120 may be installed on the left side with respect to the center line C of the slider body 110 and may be inserted into the element row 54 passing through the left side of the element passage 114. In this case, the mounting portion 124 extends rightward from the claw portion 126, offsetting the claw portion 126 to the left, the base portion 118 is installed to the right of the claw hole 117 and in the right wall portion 116b, allowing the claw portion 126 to pass through the claw hole 117 near the base portion 118, and the position restricting portion 140 is installed between the right wall portion 116b and the mounting portion 124 (i.e., the right side of the mounting portion 124 is restricted in position by abutment with the position restricting portion 140), thereby preventing the mounting portion 124 from displacing to the right in the width direction W. In other words, the positions of the claw portion 126, the mounting portion 124, the base portion 118, etc. can be adjusted as necessary. Furthermore, the present invention does not limit the shape of the lock pin 120, and in the subsequent second modified example, the lock pin may be T-shaped (described below) as long as it has a mounting portion where the lock pin is placed on the base portion and a claw portion that extends downward and passes through the claw hole, and can be adjusted as needed.

[0028] As can be seen from this, in this embodiment, as shown in Fig. 2, with the slider 100 (shown by a dashed line in Fig. 2) attached to the fastener chain 50, the slider body 110 shown in Figs. 1 and 3 slides relative to the fastener chain 50 when driven by the pull tab 130, thereby opening and closing the element row 54. For example, the slider body 110 moves upward when driven by the pull tab 130 to close the element row 54, and moves downward when driven by the pull tab 130 to open the element row 54 (but is not limited to this). During this process, as shown in FIG. 4, the claw portion 126 of the lock pin 120 is installed offset with respect to the center line C of the slider body 110 (for example, installed offset to the right), so that when a pair of element rows 54 of the fastener chain 50 pass through the element passage 114 in the slider body 110, the claw portion 126 of the lock pin 120 is inserted into one of the pair of element rows 54 passing through the element passage 114 (for example, the right element row 54) (for example, inserted between two elements of the element rows 54) to perform locking, making the slider body 110 unable to slide relative to the fastener chain 50, and the placement portion 124 suppresses displacement in the width direction W by the position restriction of the position restriction portion 140, thereby ensuring the locking strength of the lock pin 120.

[0029] In this embodiment, the slider 100 is further provided with a pull tab 130 that interlocks with the lock pin 120. Therefore, the lock pin 120 in the locked state shown in FIG. 4 can be unlocked by driving the pull tab 130. For example, when the pull tab 130 is pulled up, the pull tab 130 drives the lock pin 120 to move upward and away from the element row 54, allowing the slider body 110 to slide on the fastener chain 50. During the sliding process of the slider body 110, the lock pin 120 maintains the unlocked state by driving the pull tab 130, maintaining smooth sliding operation. At this time, the claw portion 126 of the lock pin 120 moves away from the element row 54. However, preferably, the mounting portion 124 is still positioned in the accommodation space S and the claw portion 126 is still positioned in the element passage 114, thereby shortening the moving distance of the lock pin 120 and maintaining stability (but not limited to this). When the pull tab 130 is released (for example, by resetting the pull tab 130 via an elastic member (not shown)), the pull tab 130 drives the lock pin 120 to move downward, whereby the mounting portion 124 of the lock pin 120 is placed on the base portion 118 and the claw portion 126 is inserted into and locked into one of the element rows 54 of the fastener chain 50 (i.e., the state shown in FIG. 4). In this way, not only can the slider body 110 be locked to the fastener chain 50 via the lock pin 120 and a good locking effect can be achieved, but also the lock pin 120 can be unlocked at the same time as the slider body 110 is driven by the pull tab 130 to slide relative to the fastener chain 50.

[0030] Furthermore, in this embodiment, when the slider 100 (shown by a dashed line in FIG. 2) moves to the end of the fastener chain 50, the pull tab 130 can be used to continue to drive the slider body 110 to pass the end insert pin 56 and box pin 58, or the slider body 110 can be directly driven by hand to pass the end insert pin 56 and box pin 58 (preferably the latter). At this time, even if the claw portion 126 is positioned in the element passage 114, it is not inserted between the last element and the insert pin 56 or box pin 58 and locked. In other words, when the slider 100 (shown by a dashed line in FIG. 2) moves to the end of the fastener chain 50, the slider body 110 is not locked, regardless of whether the pull tab 130 is pulled. Correspondingly, the insert pin 56 and box pin 58 are inserted into the slider body 110 from bottom to top. Here, as shown in FIGS. 5 and 6, the claw portion 126 of the lock pin 120 is installed offset with respect to the center line C of the slider main body 110 (for example, installed offset to the right), so when the box pin 58 on the left side of the fastener chain 50 is inserted into the slider main body 110 and passes through the element passage 114 (the box pin 58 is omitted in FIG. 5 and is shown as being installed on the left side in FIG. 6), the box pin 58 can pass through the element passage 114 smoothly without coming into contact with the claw portion 126 of the lock pin 120, and when the insert pin 56 provided on the right side of the fastener chain 50 is inserted into the slider main body 110 and passes through the element passage 114 (the insert pin 56 is shown as being installed on the right side in FIGS. 5 and 6), the insert pin 56 comes into contact with the claw portion 126 of the lock pin 120, but can also pass through the element passage 114 smoothly.

[0031] More specifically, in this embodiment, as shown in FIGS. 5 and 6, a gap 119 through which the mounting portion 124 moves is provided above the base portion 118. Therefore, when the insert pin 56 of the fastener chain 50 is inserted into the slider body 110 and passes through the element passage 114, as shown in the operation schematic diagrams of FIGS. 6 to 8, the claw portion 126 of the lock pin 120 rotates under the pressure of the insert pin 56 (for example, the insert pin 56 located on the right side presses the claw portion 126 that is installed offset to the right, causing it to rotate clockwise toward the left and upward), and can move beyond the position regulating portion 140 to the upper gap 119 (for example, the claw portion 126 moves upward along the surface of the position regulating portion 140). That is, the position restricting portion 140 restricts the position of the mounting portion 124 in the width direction W (for example, restricts displacement of the mounting portion 124 to the left), but the rotation of the claw portion 126 is accompanied by an upward movement component, so that the claw portion 126 can overcome the position restriction of the position restricting portion 140 and move into the gap portion 119 provided above the base portion 118, thereby moving the claw portion 126 in the direction of the center line C and giving way to the element passage 114 to allow the insert pin 56 to pass through. To summarize all the structural features, the slider 100 of this embodiment combines the locking strength of the lock pin 120 and the insertion effect of the insert pin 56, and has good operability.

[0032] However, the above-described method in which the position restricting portion 140 restricts the position of the mounting portion 124 in the width direction W (see FIG. 4), the method in which the pull tab 130 unlocks the lock pin 120, and the operation method in which the insert pin 56 presses the claw portion 126 (see FIGS. 6 to 8) are merely examples. For example, in another embodiment (not shown), if the claw portion 126 of the lock pin 120 is installed offset to the left with respect to the center line C of the slider body 110, the claw portion 126 can be inserted into and locked into the element row 54 passing through the left side of the element passage 114, and the position restricting portion 140 is installed on the right side to restrict displacement of the mounting portion 124 to the right in the width direction W. Furthermore, insert pin 56 is installed at the end of left element row 54 and can pass through left element passage 114, and claw portion 126 installed offset to the left side of lock pin 120 rotates under pressure from left insert pin 56 and can move over position restriction portion 140 installed on the right side into upper gap 119. In this way, the position restriction method of position restriction portion 140, the unlocking method of pull tab 130, and the operation method of insert pin 56 can be adjusted as needed based on changes in the components such as the slider body 110, lock pin 120, and position restriction portion 140 described above, and the present invention is not limited thereto.

[0033] Up to this point, we have described variations on the components of the slider 100, such as the slider body 110, the lock pin 120, and the position restriction portion 140, but other variations are also included. For example, in the embodiment shown in FIG. 3, the base portion 118 of the slider body 110 of the slider 100 is provided with a position restriction portion 140 that restricts the position of the mounting portion 124 in the width direction W. Correspondingly, in a first modified example shown in FIG. 9, the mounting portion 124A of the lock pin 120A of the slider 100A is provided with a position restriction portion 140A that restricts the position of the mounting portion 124A in the width direction W. In other words, the installation position of the position restriction portion 140A is adjusted.

[0034] 9, a position restricting portion 140A that restricts the position of the mounting portion 124A in the width direction W is provided on the mounting portion 124A of the lock pin 120A of the slider 100A, and the position restricting portion 140A is installed on the side adjacent to the claw portion 126A of the mounting portion 124A, for example, at the corner between the mounting portion 124A and the claw portion 126A, and restricts displacement of the mounting portion 124A relative to the base portion 118A in the width direction W. In other words, when the mounting portion 124A is placed on the base portion 118A, one side (for example, the left side) of the mounting portion 124A restrains unexpected displacement of the mounting portion 124A in the width direction W by contacting the position restricting portion 140A. Preferably, position regulating portion 140A includes an inclined surface that slopes downward from mounting portion 124A toward claw portion 126A (for example, the inclination angle is between 30 degrees and 60 degrees). The inclined surface may be a flat surface as shown in FIG. 9, or may be a protruding arc surface. The present invention does not limit the specific structure of position regulating portion 140A installed on mounting portion 124A, and the structure can be adjusted as necessary.

[0035] Furthermore, in a first modified example shown in FIG. 9, the slider body 110A of the slider 100A is similarly provided with a gap 119A located above the base portion 118A in the accommodation space S, through which the mounting portion 124A moves. Preferably, the gap 119A is located above the position restricting portion 140A in the vertical direction (i.e., the thickness direction T of the slider body 110A). In this manner, the gap 119A can serve as a movement space for the mounting portion 124A of the lock pin 120A during or after overcoming the position restriction of the position restricting portion 140A. Also, in the first modified example shown in FIG. 9, the claw portion 126A of the lock pin 120A is installed offset with respect to the center line C of the slider body 110A (for example, installed offset to the right) and can be inserted into one of a pair of element rows 54 passing through the element passage 114 (for example, the right element row 54). As an example, the mounting portion 124A and the claw portion 126A are connected to each other to form an L-shaped structure, the base portion 118A is installed on one side (e.g., the left side) of the claw hole 117A and on one side (e.g., the left wall portion 116a) of the pair of walls 116a, 116b, the claw portion 126A is passed through the claw hole 117A near the base portion 118A, and the position restricting portion 140A is installed between the claw portion 126A and the base portion 118A. In this way, when the mounting portion 124A protruding leftward relative to the claw portion 126A is placed on the base portion 118A installed on the left side of the storage space S, one side (e.g., the left side) of the mounting portion 124A is restricted in position by abutment of the position restricting portion 140A, thereby suppressing displacement of the mounting portion 124A to the left in the width direction W.

[0036] As can be seen from this, in the first modified example shown in Figure 9, the slider 100A also has the three-dimensional structure of the slider 100 shown in Figure 1 (i.e., including the slider body 110A, lock pin 120A, pull tab 130, and position restriction portion 140A) and may be attached to the fastener chain 50 shown in Figure 2. The main difference between the slider 100A and the previously described slider 100 is that the installation position of the position restriction portion 140A is different from the setting position of the previously described position restriction portion 140, and the slider body 110A and the lock pin 120A are adjusted according to the installation position of the position restriction portion 140A. However, based on the specific structures and installation positions of the slider body 110A, lock pin 120A, and position restriction portion 140A, the slider 100A may have the same operation method as the previously described slider 100. That is, with the slider 100A attached to the fastener chain 50 (see FIG. 2), the slider body 110A slides relative to the fastener chain 50 by driving the pull tab 130, thereby opening and closing the element rows 54. During this process, when a pair of element rows 54 of the fastener chain 50 pass through the element passage 114 of the slider body 110A, the claw portion 126A of the lock pin 120A can be inserted into and locked into one of the element rows 54 passing through the element passage 114 (e.g., the right element row 54) like the claw portion 126 shown in FIG. 4. Furthermore, the position restriction of the position restriction portion 140A restricts displacement of the mounting portion 124A in the width direction W, thereby ensuring the locking strength of the lock pin 120A. After this, the lock pin 120A in the locked state can be released by driving the pull tab 130. In this way, not only can the slider body 110A be locked to the fastener chain 50 via the lock pin 120A with good locking effect, but also the lock pin 120A can be unlocked at the same time when the slider body 110A is driven by the pull tab 130 to slide relative to the fastener chain 50.

[0037] 9, in the sliding process of the slider body 110A, the lock pin 120A maintains an unlocked state by driving the pull tab 130. In this process, when the insert pin 56 of the fastener chain 50 shown in FIGS. 5 and 6 is inserted into the slider body 110A and passes through the element passage 114, the claw portion 126A of the lock pin 120A rotates under the pressure of the insert pin 56, like the claw portion 126 shown in the operation schematic diagrams of FIGS. 6 to 8, and can move beyond the position restriction portion 140A to the upper gap portion 119A. That is, the position restriction portion 140A restricts the position of the mounting portion 124A in the width direction W relative to the mounting portion 124A (for example, restricting displacement of the mounting portion 124A to the left), but because the rotation of the claw portion 126A involves an upward movement component, it can overcome the position restriction of the position restriction portion 140A and move into the gap portion 119A provided above the base portion 118A, thereby moving the claw portion 126A in the direction of the center line C, giving way to the element passage 114 and allowing the insert pin 56 to pass through. As can be seen from this, the present invention does not limit the installation positions of the position restriction portions 140 and 140A and can adjust them as necessary. To summarize all the structural features, the slider 100A of this embodiment combines the locking strength of the lock pin 120A and the insertion effect of the insert pin 56, resulting in good operability.

[0038] 3, the mounting portion 124 and the claw portion 126 of the lock pin 120 are connected to each other to form an L-shaped structure, the base portion 118 is installed on one side (e.g., the left side) of the claw hole 117 and on one side (e.g., the left wall portion 116a) of the pair of wall portions 116a, 116b, the claw portion 126 is passed through the claw hole 117 near the base portion 118, and the position restricting portion 140 is installed between one side (e.g., the left wall portion 116a) of the pair of wall portions 116a, 116b and the mounting portion 124. In a first modified example shown in FIG. 9, the mounting portion 124A and the claw portion 126A of the lock pin 120A are connected to each other to form an L-shaped structure, and the position restricting portion 140A is provided between the claw portion 126A and the base portion 118A. Correspondingly, in the second modified example shown in FIG. 10, the mounting portion 124B and the claw portion 126B of the lock pin 120B of the slider 100B are connected to each other to form a T-shaped structure, the pair of base portions 118B are installed on opposite sides of the claw hole 117B and on both of the pair of wall portions 116a, 116b, the claw portion 126B is passed through the claw hole 117B between the pair of base portions 118B, and the position regulating portion 140B is installed between one side of the pair of wall portions 116a, 116b (for example, the left wall portion 116a) and the mounting portion 124B.

[0039] 10, the claw portion 126B of the lock pin 120B is installed offset with respect to the center line C of the slider body 110B (for example, installed offset to the right), and can be inserted into one of a pair of element rows 54 (for example, the right element row 54) passing through the element passage 114. As an example, the mounting portion 124B and the claw portion 126B of the lock pin 120B of the slider 100B are connected to each other to form a T-shaped structure, and for example, the pair of mounting portions 124B extend to the left and right, respectively, with respect to the claw portion 126B, and the dimension in the width direction W of the left mounting portion 124B is larger than the dimension in the width direction W of the right mounting portion 124B, so that the claw portion 126B is installed offset to the right. Furthermore, the slider body 110B is provided with a pair of seat portions 118B located on both opposing sides of the claw hole 117B and on both of the pair of wall portions 116a, 116b corresponding to the pair of mounting portions 124B, so that the claw portion 126B passes through the claw hole 117B between the pair of seat portions 118B. Also, a position restricting portion 140B is provided between one side of the pair of wall portions 116a, 116b (for example, the left wall portion 116a) and the mounting portion 124B. That is, a pair of mounting portions 124B and a pair of seat portions 118B are provided, but preferably, one side is provided with a single position restricting portion 140B (however, the present invention does not exclude a method in which a pair of position restricting portions 140B are provided). In this way, when a pair of mounting portions 124B are placed on a pair of base portions 118B provided on opposite sides of the storage space S, one side (e.g., the left side) of the mounting portion 124B is positionally restricted by contact with the position restricting portion 140B, thereby suppressing displacement of the mounting portion 124B to the left side in the width direction W.

[0040] 10, the slider body 110B of the slider 100B is similarly provided with a gap 119B located above the base portion 118B in the accommodation space S, through which the mounting portion 124B moves. Preferably, the gap 119B is located above the position restriction portion 140B in the vertical direction (i.e., the thickness direction T of the slider body 110B). In this way, the gap 119B can serve as a movement space for the mounting portion 124B of the lock pin 120B after overcoming the position restriction of the position restriction portion 140B. Furthermore, in the second modified example shown in FIG. 10, the position regulating portion 140B is installed between one side of the pair of wall portions 116a, 116b (for example, the left wall portion 116a) and the mounting portion 124B, and regulates the displacement of the mounting portion 124B relative to the base portion 118B in the width direction W, but in other embodiments not shown, the position regulating portion 140B may be installed on the side adjacent to the claw portion 126B of the mounting portion 124B (which may be an inclined surface, etc.), and may be installed between the claw portion 126B and one of the base portions 118B.

[0041] As can be seen from this, in the second modified example shown in Figure 10, the slider 100B also has the three-dimensional structure of the slider 100 shown in Figure 1 (i.e., including the slider body 110B, lock pin 120B, pull tab 130, and position restriction portion 140B), and may be attached to the fastener chain 50 shown in Figure 2, and the main difference between the slider 100B and the aforementioned slider 100 is that the specific structures of the slider body 110B and lock pin 120B are different from the specific structures of the slider body 110 and lock pin 120. However, based on the specific structures and installation positions of the slider body 110B, lock pin 120B, and position restriction portion 140B, the slider 100B may have the same operation method as the aforementioned slider 100. That is, with the slider 100B attached to the fastener chain 50 (see FIG. 2), the slider body 110B slides relative to the fastener chain 50 by driving the pull tab 130, thereby opening and closing the element rows 54. During this process, when a pair of element rows 54 of the fastener chain 50 pass through the element passage 114 of the slider body 110B, the claw portion 126B of the lock pin 120B can be inserted into and locked into one of the element rows 54 passing through the element passage 114 (e.g., the right element row 54) as shown in FIG. 4, and the mounting portion 124B can be restricted from displacement in the width direction W by the position restriction portion 140B, thereby ensuring the locking strength of the lock pin 120B. After this, the lock pin 120B in the locked state can be unlocked by driving the pull tab 130. In this way, not only can the slider body 110B be locked to the fastener chain 50 via the lock pin 120B and have a good locking effect, but also, when the slider body 110B is driven by the pull tab 130 to slide relative to the fastener chain 50, the lock pin 120B can be unlocked at the same time.

[0042] 10, in the sliding process of the slider body 110B, the lock pin 120B maintains an unlocked state by driving the pull tab 130. In this process, when the insert pin 56 of the fastener chain 50 shown in FIGS. 5 and 6 is inserted into the slider body 110B and passes through the element passage 114, the claw portion 126B of the lock pin 120B rotates under the pressure of the insert pin 56, like the claw portion 126 shown in the operation schematic diagrams of FIGS. 6 to 8, and can move beyond the position restriction portion 140B to the upper gap portion 119B. That is, the position restricting portion 140B restricts the position of the mounting portion 124B in the width direction W (for example, restricts displacement of the mounting portion 124B to the left), but because the rotation of the claw portion 126B involves an upward movement component, it can overcome the position restriction of the position restricting portion 140B and move into the gap portion 119B provided above the base portion 118B, thereby moving the claw portion 126B in the direction of the center line C and giving way to the element passage 114 so that the insert pin 56 can pass through. As can be seen from this, the present invention does not limit the specific structures of the slider bodies 110 and 110B and the lock pins 120 and 120B, and these can be adjusted as necessary. To summarize all structural features, the slider 100B of this embodiment combines the locking strength of the lock pin 120B and the insertion effect of the insert pin 56, resulting in good operability.

[0043] In summary, in the slider of the present invention, one of the base portion of the slider body and the mounting portion of the lock pin is provided with a position restricting portion that restricts the position of the mounting portion in the width direction, and a gap portion through which the mounting portion moves is provided above the base portion in the accommodation space formed by a pair of wall portions of the slider body, and the mounting portion and an inner wall on one side of the pair of wall portions are installed at a distance to form the gap. Preferably, the claw portion of the lock pin is installed offset with respect to the center line of the slider body. In this way, when a pair of element rows of the fastener chain pass through the element passage of the slider body, the claw portion of the lock pin can be inserted into one of the element rows to lock them, and the position restriction of the position restricting portion restricts the mounting portion from moving in the width direction, thereby ensuring the locking strength of the lock pin. Correspondingly, when the insert pin of the fastener chain is inserted into the slider body and passes through the element passage, the claw portion of the lock pin is able to rotate under the pressure of the insert pin and moves toward the gap beyond the position restricting portion, thereby preventing the lock pin from interfering with the insertion of the insert pin. Therefore, the slider of the present invention has both the locking strength of the lock pin and the insert pin insertion effect, and can have good operability.
