Description

Slides for zippers and zippers

The present invention relates to a slider for a zipper and a zipper, and more particularly to a chain stopper for a so-called "back surface" having a surface on which a coiled sprocket is mounted as a back surface. The zipper of the slider and the slider used in the zipper.

As one type of zipper, it is known that a stopper mechanism is incorporated in a slider that opens and closes between left and right chain cloths by a user moving through a tab, and an example thereof is disclosed in Japanese Patent Laid-Open No. 63- Bulletin No. 145605 and the like. The stopping mechanism includes: a cam shaft that rotatably couples the pull tab to the upper wing of the sliding member; and a leaf spring portion that is in an initial position when the user does not hold the pull tab, when the user pulls When the tab is pulled, displacement is performed from the initial position by the action of the cam shaft; and the stopping claw is formed at one end of the leaf spring portion, and at the initial position of the leaf spring portion, the claw hole from the upper flap is opposite to The sprocket guiding path inside the slider protrudes. The protruding claw of the protruding state abuts against the sprocket just before or immediately after the sprocket guiding path, and the abutting becomes resistance and prevents the movement of the slider. On the other hand, when the user holds the pull tab, the leaf spring portion is displaced, and the stop claw of the protruding state is pulled back from the element guide path, whereby the slider becomes movable.

Further, the chain cloth to which the coiled element (sprocket) is attached to one surface is usually used as the front surface (for the front surface) of the chain cloth, but the chain side is set as the chain cloth for other reasons such as fashion. The case on the back (for the back). In the case of the front side, there are sprocket teeth between the upper wing of the slider and the chain cloth, whereas in the case of the back surface, a chain cloth is disposed between the upper wing and the sprocket. Therefore, when the above-described stopper mechanism formed in the front surface is applied to the back surface, the engagement between the stopper claw and the fastener element is insufficient, and the stopper function cannot be effectively utilized. Further, if the stopper mechanism for the back surface is manufactured separately from the stopper mechanism for the front surface, the cost increases, and the parts management and the like become complicated.

In this case, the second upper surface can regulate the posture of the coil-shaped sprocket on the meshing port side of the element guide path, thereby reliably maintaining the meshing state of the meshing heads of the left and right coil-shaped sprocket. Further, since the first upper surface and the second upper surface are coupled via the inclined surface, the left and right coil-shaped fastener elements can be meshed or separated in the element guiding path, and the first upper surface and the first upper surface can be formed on the raised portion. 2 The upper surface moves smoothly.

According to another aspect of the invention, a slider for a zipper is provided, comprising: a slider body including a wing plate having a claw hole, a lower wing plate, and a guide post connecting the upper and lower wing plates; a stop mechanism for preventing movement of the slider body; the slider body comprises: an introduction port, which is open to the left and right of the guide post between the upper and lower wings; the engagement port, the guide post in the front and rear direction a Y-shaped sprocket guiding path formed between the introduction port and the engaging opening; the stopping mechanism includes a stopping claw protruding from the claw hole of the upper blade toward the sprocket guiding path, the lower part The flap has a ridge extending from the guide post toward the engagement opening in the front-rear direction on the inner side surface thereof, and the ridge portion has a first upper surface at a highest level on the ridge portion on the guide post side, and is lower than the first portion The second upper surface of the upper surface of the engagement opening side faces the first upper surface in a state in which the stopper claw protrudes into the element guide path.

In the present invention, in the slider for the zipper, a ridge portion is provided on the inner side surface of the lower wing of the slider main body. The ridge portion has a first upper surface at a highest level (parallel to the inner side surface of the lower blade) on the ridge portion on the side of the guide post, and the stopping claw of the stopper mechanism protrudes from the claw hole toward the sprocket guiding path. Opposes the first upper surface. The unit element teeth adjacent to the coil-shaped element teeth on the first upper surface in the front-rear direction are engaged with the stopper claws in a state in which the posture is stabilized at the same height position. The second upper surface lower than the engagement opening side of the first upper surface can regulate the posture of the coiled element on the engagement opening side of the element guide path, thereby reliably maintaining the meshing head of the left and right coiled elements Engagement state. The second upper surface may be horizontal or inclined. When the second upper surface is horizontal, the first upper surface and the second upper surface may be coupled via an inclined surface. When the second upper surface is inclined, the second upper surface may extend from the engagement port side end of the first upper surface to the engagement port side end of the ridge portion.

In one embodiment of the present invention, the first upper surface includes the same width portion on the side of the fixed engagement port at which the interval between the left and right end edges is fixed, and the interval between the left and right end edges is from the guide column side end of the same width portion. The widened portion gradually enlarged on the side of the guide post, and the first upper surface extends to the engagement opening side at least to the intersection of the extension lines of the left and right end sides of the widened portion.

Therefore, the stopper mechanism formed in the front surface on which the surface on which the coil-shaped element is attached to the chain cloth is used as the front surface can be applied to the back surface on which the surface on which the coil-shaped element is attached to the chain cloth is used as the back surface. .

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. Fig. 1 is a partial side elevational view schematically showing a slide fastener 1 according to an embodiment of the present invention. Fig. 2 is a partial cross-sectional plan view showing a lower side of the lower blade 30 as seen from line A-A of Fig. 1, and left and right coiled sprocket 11 (11a, 11b) are indicated by broken lines. Fig. 3 is a longitudinal cross-sectional explanatory view of the zipper 1 as seen from the line B-B of Fig. 2. The zipper 1 includes a pair of chain cloths 10 (10a, 10b) on the left and right (hereinafter, left and right and up and down based on Fig. 3, which are left and right and up and down with respect to the paper surface of Fig. 3); a pair of left and right coiled sprocket teeth (hereinafter, also referred to as a "chain tooth" 11 (11a, 11b) which is sewn to the opposite edge (opening and closing edge) side end portion of the back surface (lower in FIGS. 1 and 3) of each of the chain fabrics 10; A sliding member for a slide fastener (hereinafter simply referred to as "slider") 20 according to the embodiment, which can be pulled by a user (see reference numeral 80 in FIG. 10 and the like), and is guided along the left and right fastener elements 11 Move in one direction or the other direction (hereinafter referred to as "front and rear direction"). For example, when the slider is moved in one direction (front direction), the left and right sprocket teeth 11 are engaged, and when the slider is moved in the other direction (rear direction), the left and right sprocket teeth are separated. The sprocket 11 winds the monofilament-shaped wire into a coil shape, and has a coil-like element that meshes with the opposing sprocket 11 to engage the head portions 12a, 12b on a part thereof. Further, the zipper 1 is a so-called "back surface" in which the surface on the side where the fastener element 11 is attached to the chain cloth 10 is used as the back surface. The left and right sprocket teeth 11a, 11b are moved forward and backward by the slider 20, and the engaging heads 12a, 12b of the sprocket 11a, 11b are engaged or disengaged, whereby the left and right chain fabrics 10a, 10b are closed or opened. In the respective fastener elements 11a and 11b on the left and right sides, a coil-receiving portion adjacent to each other in the front-rear direction is referred to as a "unit element tooth" (see reference numeral 11c in Fig. 8). The slider 20 has a slider body (hereinafter also referred to as "body") 21, which includes an upper blade 22, a lower blade 30, and a guide post 23 connecting the upper and lower blade plates 22, 30; The pull tab is rotatably coupled to the upper portion of the upper portion of the main body 21 via the pull tab shaft portion 44; and the stop mechanism 40 is mounted on the upper surface of the main body 21 of the flap 22, and is not used by the user. When the pull tab is held, the movement of the slider 20 can be prevented. Further, the pull tab may also constitute one of the components of the stop mechanism 40. The main body 21 includes two inlet ports 26 between the upper flap 22 and the lower flap 30, opening to the left and right of the guide post 23, and passing the sprocket 11a, 11b in the separated state; a meshing opening 27, It is opened to the opposite side of the guide post 23 in the front-rear direction, and the sprocket 11a, 11b for the meshing state passes; and a Y-shaped sprocket guide path 28 formed at the introduction port 26 and the engagement port 27 between. Further, reference numerals 29 and 36 form the side guides of the upper and lower side flaps 22 and 30 on the left and right side portions of the element guide path 28, and the chain guides 28a and 11b pass through the element guide path 28, and the chain is removed. The chain cloths 10a and 10b outside the attachment portions of the teeth 11a and 11b pass through the gap between the upper and lower side guide plates 29 and 36. The upper side guide plates 29 project downward from the left and right side edges of the upper wing plate 22. The lower side guides 36 project upward from the left and right side edges of the lower wing 30 and protrude longer than the upper side guides 29. Further, the lower guide 36 is located at the end opposite to the meshing head portions 12a and 12b of the fastener elements 11a and 11b, and functions as a U-shaped reverse portion that connects the unit chain fingers 11c (see FIG. 8). 13a, 13b (refer to Fig. 3) perform the guiding action.

The stopper mechanism 40 may use a stopper mechanism used in a slider for a zipper which has been conventionally existing, or may be the same as those disclosed in Japanese Laid-Open Patent Publication No. Sho 63-145605, for example, The stopper member 41 of the stopping claw 42 at one end and the leaf spring 45 biased so that the stopping claw 42 of the stopper member 41 protrudes into the element guiding path 28 are housed inside the covering member 24, A pull tab shaft portion 44 of the pull tab is disposed between the stopper member 41 and the upper surface of the upper flap 22, so that the pull tab is attached to the main body 21. When the user does not hold the pull tab, the stopping claw 42 is biased downward from the claw hole 43 (refer to FIG. 6) provided on the upper blade 22 by the elastic biasing force of the leaf spring 45. In the sprocket guiding path 28, the sprocket 11 (refer to FIG. 2) just before or immediately after the engagement is abutted, so that the abutment becomes resistance and the movement of the slider 20 can be prevented. On the other hand, if the user holds the pull tab to operate, the pull tab stands up relative to the upper wing 22, and the pull tab shaft portion 44 of the pull tab competes with the elastic biasing force of the leaf spring 45 to displace the stop member 41. This counterbalance pulls the protruding claw 42 of the protruding state back upward, so that the slider 20 becomes movable. If the user releases the pull tab from this state, the stop pawl 42 returns to the protruding state. The claw hole 43 is disposed slightly to the right in the center in the left-right direction of the upper blade 22 when viewed from the paper surface of FIG. 2 (in FIG. 6 in which the upper blade 22 is viewed from below, the claw hole 43 is slightly to the left side from the center) . Therefore, as shown in Fig. 2, the projecting claw 42 of the projecting state is engaged with the engaging head portion 12b of the sprocket 11b immediately before or just after the meshing. The stopper mechanism 40 is formed in a so-called "front side" which is used as a front surface as a general surface on which the side of the chain cloth on which the coil-shaped fastener elements are attached. Therefore, as described above, in the zipper 1 for the back surface, the chain cloth 10 is present between the sprocket 11 and the lower surface of the upper blade 22, and the position of the coiled sprocket is shifted downward as compared with the front surface. Therefore, the stopper claw 42 in the protruding state does not firmly engage with the fastener element, and the stopper function does not sufficiently exert its effect. In order to correct this aspect, the slider 20 under the slider 20 of the zipper 1 is constructed as follows. As described above, in the zipper for "back surface", the sprocket 11 is provided on the back side of the chain fabric 10, so that the sprocket 11 is located on the side of the lower blade 30 as shown in FIG. 3, and above the sprocket 11 and the lower blade 30 The surface is in contact with the upper surface of the raised portion 32 described below. In particular, the ridges 32 are formed to protrude more from the upper surface 31 of the lower blade 30 in order to regulate the posture of the sprocket 11 in the sprocket guiding path 28 so as to be more easily contacted with the sprocket 11.

4 is a perspective view of the lower wing 30, and FIG. 5 is a horizontal sectional view showing the upper surface (inner side surface) 31 of the guide post 23 and the lower guide 36 below the side guide 36. The lower blade 30 has a raised portion 32 on the upper surface 31. The raised portion 32 is in the center in the left-right direction, and the lower end portions of the left and right sides of the guide post 23 extend in the front-rear direction to the vicinity of the engaging opening 27. The upper surface 31 of the lower wing 30 is orthogonal to the up and down direction and is parallel to the lower surface of the upper wing 22. Hereinafter, the surface parallel to the upper surface 31 will be referred to as "horizontal (face)". As shown in FIG. 7 and the like, the raised portion 32 includes a flat and horizontal first upper surface 33 on the side of the guide post 23, and a flat and horizontal second upper surface 34 on the side of the engaging opening 27, which is spaced from the lower flap 30. The inner side surface 31 has a height slightly lower than the first upper surface 33; and the inclined surface 35 connects the first upper surface 33 and the second upper surface 34. The inclined surface 35 is inclined downward from the first upper surface 33 toward the second upper surface 34 (the height from the upper surface 31 of the lower flap 30 gradually decreases from the side of the guide post 23 toward the engaging opening 27). The height (the protruding dimension) of the ridge portion 32 from the inner side surface 31 is such that the side of the guide post 23 is higher than the side of the engaging opening 27. The first upper surface 33 is separated from the left and right sides of the lower end portion of the guide post 23 on the side of the guide post 23 so as to extend to the side opposite to the engagement opening 27 of the guide post 23 before the rear end end. . The width of the first upper surface 33 in the left-right direction is larger on the side of the guide post 23 than on the side of the engagement opening 27. The first upper surface 33a includes the same width portion 33b on the side of the engagement opening 27, which is adjacent to the inclined surface 35, and the left and right end sides are parallel to each other and the interval between the left and right end sides becomes fixed; and the widened portion 33c has left and right ends The interval between the sides 33e and 33e (including only the total width of the recess 33d shown in Fig. 4) gradually increases from the side (front) end of the guide post 23 of the same width portion 33b. The first upper surface 33 extends from the side end of the guide post 23 of the widening portion 33c to the lower end portions of the left and right side faces of the guide post 23. Referring to Fig. 5, the left and right end sides 33e, 33e of the widened portion 33c are inclined with respect to the left and right end sides of the same width portion 33b, and if the extension of each of the end edges 33e, 33e intersects the upper surface of the raised portion 32, When the point is set to the point P, the first upper surface 33 of the same width portion 33b is formed so as to extend at least from the side of the guide post 23 toward the engagement opening 27 side to the point P. In other words, the second upper surface 34 and the inclined surface 35 are disposed closer to the meshing port 27 than the point P. Further, the inclined surface 35 may be disposed directly on the meshing port 27 side from the position of the point P. The end portion of the swelled portion 32 on the side of the engaging opening 27 is gently inclined toward the upper surface 31 from the side of the engaging opening 27 of the second upper surface 34. Referring also to Fig. 2, the first upper surface 33 is located in the sprocket guiding path 28, and the engaging heads 12a, 12b of the left and right sprocket 11a, 11b are immediately before or just after the engagement (before meshing / In the region immediately after separation, the region includes the claw holes 43 in which the stopping claws 42 of the stopper mechanism 40 are seen as described above. The claw hole 43 is located at a position opposed to the substantially boundary between the same width portion 33b and the widening portion 33c of the first upper surface 33. Thereby, when the stopper claw 42 protrudes from the claw hole 43 into the element guide path 28, it is disposed so as to face the substantially boundary of the same width portion 33b and the widening portion 33c of the first upper surface 33. The second upper surface 34 is located in the region (post-engagement/pre-separation region) after the left and right sprocket 11a, 11b in the sprocket guiding path 28 is engaged or before the separation. The inclined surface 35 is located in the region between the aforementioned pre-engagement/just-separated region and the post-engagement/pre-separation region in the sprocket guiding path 28, in which the meshing heads of the left and right sprocket 11a, 11b are located 12a, 12b begin to engage or separate.

Fig. 6 is a view showing the lower surface of the guide plate 23 and the side guide plate 29 above the wing plate 22 in a horizontal section. The upper blade 22 has a raised portion 25 on the lower surface, and the raised portion 25 is near the center in the left-right direction, and is on the left side (the right side in FIG. 6) of the guide post 23 toward the meshing port 27 side in the front-rear direction. extend. The raised portion 25 is located only on the left side (the right side in FIG. 6) from the center line in the left-right direction, and is provided with the claw holes 43 as described above on the right side (the left side in FIG. 6) from the center line in the left-right direction. The width of the swelled portion 25 in the left-right direction is gradually reduced from the guide post 23 toward the engagement opening 27 side to the side of the engagement opening 27 of the claw hole 43, and then slightly extended by the fixed width, but is more raised than the swell of the lower blade 30. 32 terminates away from the engagement opening 27. Further, the width of the raised portion 32 of the lower blade 30 in the left-right direction is larger than the width of the raised portion 25 of the upper blade 22. Fig. 7 is an explanatory view of the ridge portion 32 of the lower blade 30, the ridge portion 25 of the upper blade 22, and the stopper claw 42 as seen from the side. The lower surface 25a of the raised portion 25 of the upper blade 22 is a flat horizontal surface, and extends toward the engagement opening 27 side to the vicinity of the boundary between the inclined surface 35 of the raised portion 32 of the lower blade 30 and the second upper surface 34.

In the zipper 1 constructed as described above, when the user does not hold the pull tab, that is, when the left and right chain fabrics 10a and 10b are not opened and closed, the stopping claws 42 of the stopper mechanism 40 are elastically applied. The force protrudes from the claw hole 43 into the element guide path 28 to be in a protruding state. At this time, the first upper surface 33 of the raised portion 32 of the lower blade 30 is slightly pulled up on the right side of the coiled element 11b in the region immediately before the engagement/just after separation in the element guide path 28. As a result, as shown in FIG. 8, the sprocket 11b approaches the stopping claw 42, so that the sprocket 11b is surely engaged with the stopping claw 42 in the protruding state. Thereby, the desired stop function works to prevent the movement of the slider 20. Further, as described above, as described above, the horizontal first upper surface 33 is formed so as to extend at least to the point P (see FIG. 5) toward the engagement opening 27 side, so that at least two adjacent to the sprocket 11b in the front-rear direction are provided. The unit element teeth 11c are mounted on the same width portion 33b of the first upper surface 33 and the widening portion 33c to have the same height position. As described above, the stopping claws 42 enter between the adjacent two unit element teeth 11c which are at the same height position on the first upper surface 33 and whose posture is adjusted, whereby there is no easy self-engaging head such as the stopping claw 42 The situation of separation between 12b, and the stop function effectively works. When the user holds the pull tab to open and close the left and right chain fabrics 10a, 10b, the slider shaft 44 is displaced by the stopper member 41 by the pull tab shaft portion 44, and the self-sprocket guiding path 28 is guided. Pull back to the upper surface of the upper wing 22 above. Thereby, the slider 20 becomes movable. At the opening and closing operation, the swelled portion 32 of the lower blade 30 slightly narrows the upper and lower intervals of the sprocket guiding path 28 through which the sprocket 11 passes, thereby reducing the engaging head portions 12a, 12b of the left and right sprocket 11a, 11b. Shake up and down. Further, since the width of the first upper surface 33 in the left-right direction is greater on the side of the guide post 23 than on the side of the engagement opening 27, the fastener elements 11a, 11b can be smoothly engaged when the left and right fastener elements 11a, 11b are engaged. The first upper surface 33 is pulled up, so that the stop claw 42 and the fastener element 11 are more reliably engaged. Further, the second upper surface 34 of the ridge portion 32 can be slightly narrowed by the upper and lower intervals of the meshing/separating region before the sprocket guiding path 28, and the engaging head portions 12a, 12b of the left and right sprocket 11a, 11b. The posture is regulated so that the engaging heads 12a, 12b are more reliably engaged. Further, it also functions to reliably maintain the meshing state of the engaging head portions 12a and 12b. When the fastener elements 11a and 11b are engaged or disengaged, the inclined surface 35 smoothly moves between the first upper surface 33 and the second upper surface 34 on the raised portion 32.

As described above, in the slide fastener 1, the stopper for the stop claw 42 and the coiled fastener element 11 is accurately engaged in the slider for the back surface, whereby the stopper mechanism can function and the front surface can be used. The stopper mechanism 40 is applied to the slide fastener 1 including the chain fabric 10 having the coiled fastener elements 11 for the back surface. Further, in the above embodiment, the first upper surface 33 of the raised portion 32 and the second upper surface 34 are connected by the inclined surface 35. However, the present invention is not limited thereto, and is shown in FIG. A modification of the ridge portion. The raised portion 32a includes a flat and horizontal first upper surface 33a on the side of the guide post 23 (except for the raised portion, the same reference numeral as in FIG. 7 and the like); and a second upper surface 34a which is The side end of the engaging opening 27 of the upper surface 33a is inclined in such a manner that the engaging opening 27 gradually becomes lower. In this case, the inclined second upper surface 34a is directly coupled to the first upper surface 33a, and the length of the first upper surface 33a in the front-rear direction is shorter than the first upper surface 33 of the ridge 32 shown in FIG. . However, although not shown, the first upper surface 33a of Fig. 9 also extends toward the engagement opening 27 side to the position of the point P of Fig. 5, in other words, the boundary between the first upper surface 33a and the second upper surface 34a is located at a point. The position of P or the position of the point P is closer to the side of the engaging hole 27. At least two unit element teeth 11c adjacent to each other in the front-rear direction of the element teeth 11b are mounted on the first upper surface 33a.

Further, in the above description, the chain fabric 10 is coated on the front surface thereof (opposite to the surface including the fastener elements 11) by a film containing a thermoplastic elastomer by an adhesive, or a thin resin is applied. Thereby, a chain fabric in which a resin layer is formed is used, and it can be used as a slider for a slide fastener having the chain cloth.

Next, a slider 50 according to a second embodiment of the present invention will be described. Fig. 10 is a side view of the slider 50, and Fig. 11 is a cross-sectional explanatory view of the slider 50 in a state before the tab 80 is attached. The slider 50 is configured in substantially the same manner as the slider for a slide fastener disclosed in Japanese Laid-Open Patent Publication No. 2008-228808, except for the ridge portion 62 provided on the upper surface 61 of the lower blade 60. Further, the slider 50 can be applied to the chain cloth 10 having the sprocket 11 on the back side instead of the slider 20 including the above-described stopper mechanism 40, and constitutes a zipper for the back surface. The slider 50 includes: a slider body 51 including an upper wing 52, a lower wing 60, and a guiding post 53 connecting the upper and lower wing plates 52, 60; and a stopping mechanism 70 assembled on the sliding The main body 51 is on the upper wing 52, and when the user does not hold the pull tab 80, the movement of the slider 50 can be prevented. The slider main body 51 has substantially the same configuration as the slider main body 21 of the slider 20 of the first embodiment except for the portion in which the stopper mechanism 70 is incorporated, and includes two inlet ports 56 on the upper flap. 52 is open to the left and right of the guide post 53 between the lower wing plate 60; the engagement opening 57 is open to the opposite side of the guide post 53 in the front-rear direction; and a Y-shaped sprocket guiding path 58 It is formed between the introduction port 56 and the engagement port 57.

The stopper mechanism 70 includes: an opening and closing member 71 which is slidably and slidably attached to the rear side of the upper surface of the upper blade 52 (leftward in FIG. 10 or the like, rightward in FIG. 10 and the like); a coil spring (not shown) that constantly urges the opening and closing member 71 rearward; a plate-shaped stopping claw 73 is disposed on the front side of the upper surface of the upper blade 52, and includes a stopping claw 72; a substantially covering a tab holding body 74 covering the upper side of the opening and closing member 71 and the periphery of the stopping claw 73; a leaf spring 75 which is substantially horizontally mounted above the inner side of the tab holding body 74 and always stops the stopping claw 73 The force is applied below; and the pull tab 80 can be installed and removed.

The opening and closing member 71 is biased rearward by the coil spring, and is usually located at the initial position shown in Figs. 10 and 11, and cannot move rearward from the initial position. The opening and closing member 71 includes an end portion 71A extending rearward and leftward, and left and right side plates 71B extending forward from both left and right end portions of the rear end portion 71A. The left and right side plates 71B have a first mountain portion 71a that is raised upward and a second mountain portion 71b that is rearward, and a valley portion 71c that is recessed downward between the first and second mountain portions 71a and 71b. The stopping claw body 73 has a base end portion 73a which is located on the front side of the upper surface of the upper blade 52 and is bulged upward, and the top portion is supported by the support portion 52a of the arc-shaped cross section; and the upper arm portion 73b and the lower arm portion 73c, which extends rearward from the base end portion 73a into two strands, and the lower end portion of the lower arm portion 73c serves as the stop pawl 72. The supported portion 73d of the proximal end portion 73a corresponding to the top of the support portion 52a has a concave arc-shaped cross section, and the stop claw 73 can oscillate slightly upward and downward with the support portion 73d as the center. The stopping claw 73 is normally placed at the initial position shown in Fig. 11 by the urging force of the leaf spring 75. At the initial position, the lower arm portion 73c is inwardly opposed to the inclined portion 52b which is inclined downward from the base end of the support portion 52a on the upper surface of the upper blade 52, so that the oscillation below the upper side is restricted. Further, the stopper claw 72 protrudes from the claw hole 52c toward the lower element guide path 58 and abuts against a fastener element (not shown), thereby preventing the movement of the slider main body 51.

The tab holding body 74 includes a backing plate 74a that is curved so as to be convex upward and extends in the front-rear direction, and left and right side plates 74b that extend downward from the left and right end sides of the backing plate 74a. The substantially front half of the back plate 74a and the left and right side plates 74b are coupled to the upper surface of the upper blade 52, and the substantially rear half of the back plate 74a and the left and right side plates 74b are spaced apart from the upper surface of the upper blade 52. The rear end portion of the back plate 74a of the tab holding body 74 has a small gap s close to the rear end portion of the opening and closing member 71 at the initial position. This small gap s is smaller than the diameter of the shaft portion 81 of the pull tab 80 described below. The left and right side plates 74b of the tab holding body 74 have a first convex portion 74c at the rear end portion which is convex downward, and the second convex portion 74d is forward of the first convex portion 74c and convex downward. The first concave portion 74e is located between the first and second convex portions 74c and 74d and is concave upward; and the second concave portion 74f is adjacent to the front of the second convex portion 74d. The first and second convex portions 74c and 74d are close to each other with respect to the first and second mountain portions 71a and 71b of the opening and closing member 71 at the initial position with a small gap smaller than the diameter of the shaft portion 81 of the tab 80. The pull tab 80 includes a pull tab body 82 (refer to FIG. 11) on which a stamp or the like can be imprinted, and a rectangular annular portion 81a extending from the pull tab body 82. The rectangular annular portion 81a has a shaft portion 81 that is held by the handle holding body 74 or the like as described below.

Next, a description will be given of a step of connecting the handle 80 to the handle holding body 74 and the like with reference to Figs. 12 to 15 . First, the shaft portion 81 of the pull tab 80 is forcibly pressed into the small gap s between the end portion 71A of the opening and closing member 71 and the rear end portion of the tab holding body 74. Thereby, the opening and closing member 71 is biased forward by the biasing force of the coil spring (FIG. 12). Then, the shaft portion 81 is moved upward into the first recessed portion 74e of the right and left side plates 74b of the tab holding body 74, whereby the opening and closing member 71 is returned to the initial position by the biasing force of the coil spring (FIG. 13). At this time, the shaft portion 81 is located in a relatively large gap between the valley portion 71c of the opening and closing member 71 and the first recess portion 74e of the tab holding body 74. Then, the second mountain portion 71b of the opening and closing member 71 of the handle holding member 74 is pressed forward by the shaft portion 81, whereby the shaft portion 81 reaches the second portion of the handle holding body 74 as shown in Fig. 14 . The recessed portion 74f corresponds to the position in the front-rear direction, and enters between the lower arm portions 73b and 73c above the stopping claw body 73. At this time, the shaft portion 81 pulls the upper arm portion 73b slightly upward, whereby the leaf spring 75 is curved so as to be slightly convex upward (FIG. 14). When the shaft portion 81 passes over the second mountain portion 71b of the opening and closing member 71, as shown in Fig. 15, the opening and closing member 71 and the leaf spring 75 are returned to the initial positions, respectively, and the attachment of the tab 80 is completed. Since it is difficult to move the opening and closing member 71 by the shaft portion 81 of the mounting completion position, the pull tab 80 cannot be removed by the pull tab 80 alone. However, the opening and closing member 71 is pressed forward from the small gap s by using another rod-shaped member or the like, whereby the above-described step can be reversely traced to separate the shaft portion 81 from the tab holding body 74.

Further, in the state of Fig. 15, the stopping claw 72 protrudes from the claw hole 52c toward the lower element guiding path 58 to prevent the movement of the slider 50. However, if the user pulls the tab 80, it is not shown. However, the shaft portion 81 stops the urging force of the claw body 73 and the leaf spring 75 to oscillate upward, whereby the stop claw 72 is pulled back from the element guide path 58, and the slider 50 becomes movable. The slider 50 has a ridge 62 on the upper surface 61 of the lower blade 60. The ridge 62 includes a flat and horizontal first upper surface 63 on the side of the guide post 53 and a meshing opening 57 slightly lower than the first upper surface 63. The second upper surface 64 which is flat and horizontal on the side and the inclined surface 65 which connects the first upper surface 63 and the second upper surface 64. The first upper surface 63 extends at least to the point corresponding to the point P of FIG. 5 toward the engagement opening 57 side. When the pawl 72 protrudes from the claw hole 52c into the element guide path 58, the stopper claw 72 is disposed to face the first upper surface 63.
