The cover body 7 has a cover body upper surface 71 and a wall portion 72 . The cover upper surface 71 is a rectangular member, and the wall portions 72 protrude from four sides respectively. On both the left and right wall portions 72 , a recessed portion 73 is formed on the side opposite to the cover upper surface 71 , and the pivot shaft 53 of the handle 5 enters the recessed portion 73 to be rotatably held during assembly. In addition, a small protrusion 74 is formed on the front wall portion 72 .

FIG. 4 is an assembled cross-sectional view of the slider 1 according to the first embodiment.

Regarding the assembly of the slider 1 of the first embodiment, first, the pivot shaft of the handle 5 is placed between the first step portion 31 provided on the upper surface 21 a of the upper wing portion 21 of the main body 2 and the guide surface 43 . 53.

Next, the stop pawl 6 is disposed toward the main body 2 from above. At this time, the claw portion 64 of the stop claw body 6 is inserted into the claw hole 44 formed in the second step portion 4 of the main body 2 , and the tip of the claw portion 64 protrudes into the guide groove 38 . In addition, the elongated hole portion 67 of the stop pawl 6 is fitted into the protruding portion 33 of the first step portion 3, and the main body portion 61 is placed on the inclined portion 32, whereby the hooking portion 63 is hooked from the front F side. The lower side D of the protruding portion 33 of the first step portion 3 . Then, the claw portion 64 side of the stop claw body 6 moves upward so as to rotate around the contact point between the protrusion portion 33 and the hook portion 63 .

Preferably, the bottom 45 is arranged on the left and right sides of the claw hole 44 , the notch 66 is arranged on the left and right sides of the claw 64 corresponding to the bottom 45 , and the hole protrusion 46 is arranged on the claw hole 44 corresponding to the bottom 45 . left and right sides. In the first embodiment, the bottom 45 , the hole protrusion 46 and the notch 66 are provided on the left L side.

Next, the cover body 7 is covered on the main body 2 from above. At this time, the small protruding piece 74 at the front end of the cover body 7 is fitted into the concave portion 34 formed in the first step portion 3 . In addition, the curved portion at the front end of the elastic piece 62 of the stop pawl 6 abuts against the back side of the cover upper surface 71 . As a result, elastic force is applied downward D to the claw portion 64 of the stop claw body 6 . At this time, the cutout portion 66 of the stop claw body 6 abuts against the bottom portion 45 and does not fall into the claw hole 44 . Therefore, the dimension at which the tip of the claw portion 64 protrudes into the guide groove 28 can be fixed.

Finally, the part of the wall 72 of the cover 7 opposite to the small protruding piece 74 is inserted into the hole 55 of the handle 5, and the recess 73 is arranged so as to avoid the pivot 53, and the cover 7 is riveted to the handle 5. The first step portion 3 and the second step portion 4 .

The operating state of the slider 1 of the first embodiment will be described.

FIG. 5 is a cross-sectional view passing through the claw hole 44 in the locked state of the slider 1 according to the first embodiment. FIG. 6 is a sectional view through the bottom portion 45 in the locked state of the slider 1 of the first embodiment. FIG. 7 is a cross-sectional view passing through the claw hole 44 in the moving state of the slider 1 according to the first embodiment.

As shown in FIG. 5 , in the assembled slider 1 , the pivot 53 is separated from the stop claw body 6 , and the curved portion 65 at the front end of the claw portion 64 is inserted between the chain elements 100 through the elastic force of the elastic piece 62 , so that The forward and backward movement of the slider 1 stops. In this stopped state, the locked state described below refers to a state in which the movement in the direction in which the slider 1 is moved backward, that is, in the direction in which the meshing of the fastener elements is released, is stopped. In the locked state, the surface on the front side of the notch 66 side of the claw 64, that is, the upper end surface of the claw 64 on the notch 66 side with respect to the horizontal end surface of the claw 64 in the left-right direction, is locked. The surface on the hook portion 63 side has a stop function of coming into contact with the hole protrusion 46 to stop. That is to say, the slider 1 will move to the rear R side, and the chain element 100 will move forward relative to the slider 1. Therefore, in the locked state, the stop claw body 6 and the claw portion 64 are forced toward the front F side, However, by making the notch 66 contact the hole protrusion 46, this force can be received, and thus firm stop can be realized. In addition, since the notch 66 is in contact with the hole protrusion 46, when the claw 65 is lifted, the hole protrusion 46 does not collide with the claw 65 or the tip of the claw 65, and the claw 65 can move smoothly. .

The hole protrusion 46 is formed above the edge of the claw hole 44 on the side of the guide groove 28 . Thus, in the claw hole 44, there is a gap between the claw portion 64 and the front wall surface 4a of the claw hole 44 below the contact portion of the hole protrusion 46 and the claw portion 64, and the claw portion 64 does not contact the front wall surface 4a. Abut. In addition, when an imaginary line is extended downward D from the edge of the front wall surface 4 a of the claw hole 44 on the guide groove side, there is a gap between the imaginary line and the tip of the claw portion 44 . In addition, as shown in FIG. 6 , the notched portion 66 of the stop claw body 6 is in contact with the bottom portion 45 that blocks a part of the claw hole 44 . That is, the bottom portion 45 functions as a stopper in such a manner that the stop claw body 6 does not fall into the claw hole 44 shown in FIG. 5 .

When lifting the handle 5 from the state shown in FIG. 5 as shown in FIG. The fastener elements 100 are pulled out, and the curved portion 65 at the tip of the claw portion 64 is also pulled out from the guide groove 28 , so that contact with the fastener elements 100 moving in the guide groove 28 does not occur. Then, when the handle 5 is moved to the front F, the slider 1 can slide freely to the front F, so that the fastener elements 100 of the left and right slide fastener chains are engaged, and the unshown slide fastener chain is closed; or, the slider 1. The long zipper chain can be freely slid to the rear B to open.

When the pull tab 5 is released in the state shown in FIG. 7, as shown in FIG. The bent portion 65 at the front end of 64 is inserted between the fastener elements 100 . In this state, the movement of the slider 1 in the front-back direction is restricted, and the movement of the slider 1 stops. At this time, the notched portion 66 side of the claw portion 64 abuts against the hole protrusion portion 46 to have a firm stop function. In addition, as shown in FIG. 6 , the notched portion 66 of the stop claw body 6 is in contact with the bottom portion 45 that blocks a part of the claw hole 44 . That is, the bottom portion 45 functions as a stopper in such a manner that the stop claw body 6 does not fall into the claw hole 44 shown in FIG. 5 .

And, in the state shown in FIG. 5, the curved portion 65 at the front end of the claw portion 64 has a gap with the front wall surface 4a of the claw hole 44, so it does not abut against the main body 2 in the claw hole 44, thereby avoiding the bending portion. 65 is clamped by the main body 2 and the chain element 100, so as shown in FIG. 7 , the handle 5 is lifted up smoothly.

In the locked state shown in FIG. 5, when a load in the opening direction of the slide fastener is applied to the slider 1, the main body 2 moves slightly toward the rear opening 27, but as shown in FIG. 66 abuts against the hole protrusion 46 of the pawl hole 44, thereby preventing further movement and ensuring the stop of the slider 1 .

Next, when the handle 5 is pulled backward, the pivot shaft 53 moves upward U along the guide surface 43 as shown in FIG. 7 . As a result, the pivot shaft 53 comes into contact with the stop claw body 6 , the stop claw body 6 is lifted up, and the claw portion 64 is pulled out from between the fastener elements 100 . Then, the slider 1 can move freely toward the back opening 27 side, and can separate and open the slide fastener chain not shown.

Thus, according to the slider 1 of the first embodiment, the hole protruding portion 46 is formed on the wall surface 4a on the front F side of the claw hole 44 at the position abutting against the claw portion 64 of the stop claw body 6, so that the The contact between the protruding portion 46 and the claw portion 64 has a firm stop function, and since the hole protruding portion 46 integrally extends from the bottom portion 45 , the claw portion 64 does not catch on the edge of the claw hole 44 on the guide groove 28 side. Therefore, the lower edge of the notch 66 is not caught on the hole protrusion 46 . Moreover, since the tip of the claw portion 64 can be separated from the wall surface 4 a of the claw hole 44 , it can be suppressed that the tip of the claw portion 64 is held between the wall surface 4 a of the claw hole 44 and the fastener element 100 and cannot move. Therefore, it is possible to provide the slider 1 that moves smoothly by releasing the locked state achieved by the stop pawl 6 .

In addition, the claw portion 64 has a curved portion 65 bent toward the hook portion 63 at the front end. Therefore, when the claw portion 64 is pulled out from the fastener element 100, the angle at which the claw portion 64 can move is close to the angle of the curved portion 65. The part 64 can be easily pulled out from the fastener element 100, and the slider 1 which operates more smoothly can be provided.

In addition, the second mounting portion 4 has a bottom portion 45 that blocks a part of the claw hole 44, and the stop claw body 6 has a cutout portion 66 that cuts out a part of the claw portion 64 so as to be in contact with the bottom portion 45. Therefore, the cutout portion 66 abuts against the bottom portion 45 to function as a stopper, thereby preventing the claw portion 64 from being too deep into the fastener element 100 .

In addition, since the hole protrusion 46 is formed above the bottom 45 in the vertical direction, the hole protrusion 46 abuts against the claw 64 above the bottom 45 in the vertical direction. Further, the wall surface 4 a of the claw hole 44 in which the bottom portion 45 is not formed does not come into contact with the claw portion 64 vertically above the curved portion 65 . Therefore, the position where the main body 2 comes into contact with the claw portion 64 and the position where it does not come into contact are arranged at separated positions in the left-right direction. Therefore, the mutual interference between the contact force of the main body 2 and the claw part 64, and the contact force of the claw part 64 and the fastener element 100 is reduced, and the slider 1 which operates more smoothly can be provided.

Next, a second embodiment will be described.

FIG. 8 is a diagram showing a stop pawl 6 of the slider 1 according to the second embodiment. FIG. 9 is a cross-sectional view passing through claw holes 44 in a locked state of the slider 1 according to the second embodiment.

In the slider 1 of the second embodiment, the claw protrusion 68 is formed on the stop claw body 6 . When assembling, the claw protruding portion 68 is inserted into the claw hole 44 toward the first mounting portion 3 , and the claw protruding portion 68 is formed in a state where the notch portion 66 and the bottom portion 45 are in contact with the main body 2 . Location. In addition, the claw protrusion 68 constitutes a protrusion in the present invention.

When a load in the opening direction is applied to the slider 1 in the locked state, the main body 2 moves slightly toward the rear opening 27 side, but as shown in FIG. The wall 4a of the slider abuts, thereby preventing further movement and ensuring the stop of the slider 1 .

Then, when the pull tab 5 is pulled backward, the pivot 53 moves upward U along the guide surface 43. As a result, the stop claw body 6 abuts against the pivot 53 and is lifted up, and the claw 64 is lifted from between the fastener elements 100. The slider 1 can be freely moved toward the rear opening 27 side, and the long chain of the zipper (not shown) can be separated and opened.

In this way, according to the slider 1 of the second embodiment, the claw protrusion 68 that contacts the wall surface 4 a on the front F side of the claw hole 44 is formed on the claw portion 64 of the stop claw body 6 . The abutment of the wall surface 4a on the front F side of the claw hole 44 has a firm stop function, and the claw protrusion 68 is in contact with the front wall surface 4a above the edge of the claw hole 44 on the guide groove 28 side. The front end of the claw portion 64 is separated from the wall surface 4a of the claw hole 44, and the claw portion 64 is not hooked on the edge of the guide groove 28 side of the claw hole 44, and the occurrence of the claw portion 64 being clamped by the wall surface 4a of the claw hole 44 can be suppressed. Thus, the slider 1 that operates smoothly can be provided. According to this situation, in the claw hole 44, there is a gap between the claw portion 64 and the front wall surface 4a of the claw hole 44 below the contact portion of the claw protrusion portion 68 and the front wall surface 4a, and the claw portion 64 does not contact the front wall surface 4a. Abut.

In addition, the slider 1 of the second embodiment shown in FIG. 9 does not have the hole protrusion 46 formed on the claw hole 44 of the main body 2 of the first embodiment shown in FIG. The claw protrusion 68 is formed thereon, and the hole protrusion 46 formed in the claw hole 44 of the main body 2 is formed. That is, the hole protruding portion 46 and the pawl protruding portion 68 may be formed on both the main body 2 and the stop pawl 6 , respectively.

FIG. 10 is a diagram showing a bottom portion 45 of the slider 1 of another example.

The bottom 45 of the claw hole 44 can also be divided into left and right sides. That is, bottoms 45 extending from the side wall portion 4c on the left L side and the side wall portion 4d on the right R side toward each other are provided, and a space is provided between these bottoms 45, and the space becomes the claw portion 64. A hole inserted toward the guide groove 28 . In this case, it is preferable that the cutouts 66 of the stop pawl 6 are also divided into left and right sides corresponding to the bottom portion 45 .

Then, the slider 1 can freely slide forward F to close the not-illustrated slide fastener chain, or the slider 1 can freely slide backward B to open the slide fastener chain.

When the handle 5 is released, as shown in FIG. 11 , the pivot 53 rotates, the claw portion 64 is inserted between the elements 100, and the slider 1 stops. At this time, as shown in FIG. 11 , the notched portion 66 of the stop claw body 6 abuts against the bottom portion 45 that blocks a part of the claw hole 44 . That is, the bottom portion 45 functions as a stopper in such a manner that the stop claw body 6 does not fall into the claw hole 44 .

When a load in the opening direction is applied to the slider 1 in this locked state, the main body 2 moves slightly toward the rear opening 27, but as shown in FIG. The protrusion 46 abuts, preventing further movement and ensuring the stop of the slider 1 .

Next, by rotating the pull tab 5 upwardly from the state shown in FIG. It can move freely toward the rear opening 27 side, and can separate and open the unillustrated fastener chain.

In this way, the slider 1 of this embodiment is provided with: a main body 2, which connects one side of the upper wing 21 and one side of the lower wing 22 through the guide post 23; The hooking portion 63 that is hooked has a claw portion 64 that moves relative to the main body 2 on the other side; : the first installation part 3, which is arranged on one side of the upper surface 21a of the upper wing plate 21, and is used to hang the hook part 63; the second installation part 4, which is arranged on the upper surface 21a of the upper wing plate 21 On the other side, a claw hole 44 for inserting the claw portion 64 is formed; In the pawl hole 44, a hole protruding portion 46 is formed at the position where the pawl body 6 and the pawl hole 44 abut respectively, so that the abutment of the hole protruding portion 46 and the pawl portion 64 has a firm stop function, and the pawl portion The front end of the claw portion 64 is separated from the wall surface 4a of the claw hole 44, thereby suppressing the situation that the front end of the claw portion 64 is clamped between the wall surface 4a of the claw hole 44 and the chain element 100 and cannot move, thereby providing smooth operation. The slider 1. In the present embodiment, the bottom portion 45 integrally extends upward U in the vertical direction from the bottom portion 45 , and a hole protrusion 46 protruding toward the rear B side is formed on the front wall surface 4 a on the front F side. In addition, the claw protrusion 68 may be formed on the stop claw body 6 , and the claw protrusion 68 may be in contact with the front wall surface 4 a of the claw hole 44 .

In addition, in the slider 1 of the present embodiment, the tip of the claw portion 64 is straight, but the tip of the claw portion 64 may have a curved portion 65 bent toward the hooking portion 63 as described in the first embodiment. Thereby, the claw part 64 can be pulled out easily from the fastener element 100, and the slider 1 which operates more smoothly can be provided.

In addition, in the slider 1 of the present embodiment, the second mounting portion has the bottom portion 45 that blocks a part of the claw hole 44 , and the stop claw body 6 has a portion that can be in contact with the bottom portion 45 by cutting out a part of the claw portion 64 . The notch portion 66 , therefore, the notch portion 66 abuts against the bottom portion 45 to function as a stopper, thereby preventing the claw portion 64 from being too deep into the fastener element 100 .

In addition, in the slider 1 of the present embodiment, the hole protrusion 46 is formed above the bottom 45 in the vertical direction, so the hole protrusion 46 and the claw 64 abut on the bottom 45 in the vertical direction. Further, the wall surface 4 a of the claw hole 44 in which the bottom portion 45 is not formed does not come into contact with the claw portion 64 vertically above the curved portion 65 . Therefore, the position where the main body 2 comes into contact with the claw portion 64 and the position where the main body 2 does not come into contact with the claw portion 64 are shifted and arranged at separated positions in the left-right direction. Therefore, the mutual interference between the contact force of the main body 2 and the claw part 64, and the contact force of the claw part 64 and the fastener element 100 is reduced, and the slider 1 which has a firmer stop function and operates smoothly can be provided.
