In the

sliders

60 and 70 described in Patent Document 1 or Patent Document 2, a concave groove-shaped member for attaching the

closing members

64 and 74 to the rear end portions of the

upper blades

65 and 75 in the

slider bodies

61 and 71. The fitting portion 66 or the insertion opening 77 needs to be formed. In the

slider body

61, 71 in which the member insertion portion 66 or the insertion opening 77 is provided in the

upper blade plates

65, 75, the

slider body

61, 71 of the

slider body

61, 71 is appropriately secured to ensure the strength of the

upper blade plates

65, 75. The material may be limited, and as a result, cost reduction may be hindered.

In the case of Patent Document 1 and Patent Document 2, the structure of the mold used for forming the

slider bodies

61 and 71 is complicated. For example, when a slider body having a cantilevered handle attachment portion is molded with a mold, a mold that opens the mold in the slider width direction may be used. However, when using a mold that opens the mold in the slider width direction for forming the

slider bodies

61 and 71 of Patent Document 1 and Patent Document 2, it is necessary to use a plurality of slide cores that move in the slider length direction. As a result, it is considered that the cost required for the mold is increased and the life of the mold is shortened.

In the case of the slider body 81 described in Patent Document 3, the first engaged portion 86 for engaging the closing member 84 with the rear end portion of the upper blade 85 and the free end portion of the pull handle attaching portion 82, and A second engaged portion 87 is provided. Further, since the closing member 84 is inserted between the free end portion of the handle attachment portion 82 in the slider body 81 and the upper blade 85, it is generally formed in a small size. In addition, the closing member 84 of Patent Document 3 is formed in a thin shape with a small dimension in the slider length direction.

Such a small and thin closing member 84 is difficult to hold when attached to the slider body 81. Further, when the closing member 84 is engaged with the slider body 81, as shown in FIG. 19, the closing member 84 is held in a predetermined posture along the slider height direction and is inserted straight toward the slider body 81. Need to be included. For this reason, the attaching operation of the closing member 84 is fine and tends to be complicated. Therefore, the slider 80 of Patent Document 3 has room for improvement in terms of assembly workability.

Furthermore, since the closing member 84 of Patent Document 3 is small and thin, elastic deformation is likely to occur in the portion of the closing member 84 that engages with the slider body 81. For example, when the assembled slider 80 of Patent Document 3 is slid in the element row separation direction (rearward) by picking and pulling the puller 83, the mounting shaft portion of the puller 83 pulled rearward contacts the closing member 84. The closing member 84 may be pressed backward by the attachment shaft portion of the handle 83. At this time, it is conceivable that the closing member 84 is easily deformed by being elastically deformed and coming off from the first engaged portion 86 and the second engaged portion 87 of the slider body 81.

Further, in the slider 80 of Patent Document 3, a puller insertion gap formed between the free end portion of the puller attachment portion 82 of the slider body 81 and the upper blade 85 tends to be narrowed. For this reason, the kind of handle which can be attached to the slider body 81 may be limited.

And a locking claw portion locked to the locking holding portion. Moreover, the 1st engaging part of this obstruction | occlusion member has the left and right insertion part inserted between the left and right projecting piece parts in the member holding part and the upper blade.

With such a slider of the present invention, a groove-like member insertion portion 66 (see FIG. 16) as described in Patent Document 1 described above or insertion as described in Patent Document 2 is performed on the upper blade of the slider body. Since the opening 77 (see FIG. 17) is not formed, it is easy to ensure the strength of the upper blade stably. In addition, the first engaged portion disposed on the upper wing plate of the slider body and the second engaged portion disposed on the free end portion can be formed using a mold that opens the mold in the slider width direction. It is possible to form in a simple shape (non-undercut shape with respect to the mold). For this reason, since the structure of the mold can be simplified as compared with the case where the

slider bodies

61 and 71 of Patent Document 1 and Patent Document 2 are formed, for example, the cost required for the mold can be reduced and the life of the mold can be reduced. Can be expected to lengthen.

Furthermore, according to the slider of the present invention, the rear end position in the slider length direction of the left and right projecting pieces of the first engaged portion is more than the rear end position in the slider length direction of the free end portion of the handle attachment portion. Arranged forward. This makes it easier to secure a wider dimension (height dimension) in the slider height direction of the handle insertion gap formed between the free end of the handle attachment portion of the slider body and the upper blade. When attaching the closing member to the slider body, it is possible to easily insert the attachment shaft portion of the handle and the closing member between the upper blade and the free end portion of the attachment portion. For this reason, the assembling workability of the slider can be improved. In addition, for example, it is possible to increase the types of pull handles that can be attached, as compared with the slider body 81 of Patent Document 3 described above, which has a narrow pull insertion space.

Particularly in this case, with respect to the slider length direction, the front end position of the member holding portion is arranged in front of the front end position of the free end portion of the handle attachment portion. Thereby, the closing member can be held more stably by the member holding portion, and the state where the closing member is engaged with the slider body can be stably maintained. In addition, with respect to the slider length direction, the rear end positions of the left and right projecting pieces are arranged in front of the intermediate position between the front end position and the rear end position of the free end. Thereby, it becomes easy to ensure the height dimension of the handle insertion gap more widely, and it is easy to insert the attachment shaft portion of the handle and the closing member between the upper blade and the free end portion of the handle attachment portion.

In the slider of the present invention, the first engaged portion disposed on the upper blade is a member abutting portion for contacting the left and right insertion portions of the closing member, and a member disposed on the ridge on the upper blade. A member guide portion extending rearward from the holding portion along the slider length direction. In this case, the member contact portion is formed at the front end portion of the first engaged portion with a dimension in the slider width direction larger than that of the holding column portion. Further, the closing member has an accommodation groove formed continuously from a gap formed between the left and right insertion portions, and the member guide portion of the first engaged portion is accommodated in the accommodation groove. Is possible.

By forming the first engaged portion and the closing member of the upper blade as described above, when the closing member is attached to the slider body, the closing member is moved along the member guide portion of the first engaged portion. The closing member can be engaged with the first engaged portion. For this reason, the assembly workability | operativity of a slider can be improved more. Further, by providing the above-described member contact portion in the first engaged portion, the closing member can be stably engaged with a predetermined position of the slider body, and the engagement state of the closing member is more stable. Can be made.

In this case, the dimension in the slider height direction from the upper blade in the member guide portion of the first engaged portion is the dimension in the slider height direction from the upper blade in the member holding portion of the first engaged portion. Is set smaller. Thereby, guidance of the closure member by a member guide part can be performed stably. In addition, even when the member guide portion is provided on the upper surface of the upper blade, it is easy to ensure the height dimension of the puller insertion gap appropriately. For this reason, it can suppress that the ease of insertion at the time of inserting the attachment shaft part and closing member of a handle due to formation of a member guide part falls.

Further, with respect to the slider length direction, the rear end position of the member guide portion in the first engaged portion is the same position as the rear end position of the free end portion of the handle attachment portion, or the rear end position of the free end portion. It is arranged behind. As a result, when the closing member is attached to the slider body, the closing member can be guided from the rear side position, so that the closing member can be attached more smoothly. Preferably, if the rear end positions of the free end portions of the member guide portion and the handle attachment portion are the same, it is possible to prevent the appearance (appearance quality) and feel of the slider from being lowered by forming the member guide portion.

Furthermore, in the slider of the present invention, the locking restriction portions for locking the closing member are provided in a pair of left and right on the second engaged portion of the free end portion of the pull attachment portion. The closing member is disposed between the base portion placed on the upper blade, the pair of left and right vertical wall portions erected on the base portion, and the left and right vertical wall portions erected on the base portion. And a left and right locking claw portion disposed as a second engaging portion at the upper end portion of the left and right vertical wall portions. The left and right locking claws are arranged to protrude from the inner wall surfaces of the left and right vertical wall portions toward the inside in the slider width direction.

The closing member having such a structure can be formed into a shape that can be formed using a mold that opens in the slider length direction (non-undercut shape with respect to the mold). In addition, since such a closing member has a shape that can be easily held by a finger or the like, it can be smoothly inserted between the upper wing plate of the slider body and the free end of the handle attachment portion, and can be firmly engaged with the slider body. Can be attached. Further, when the slider of the present invention is slid in the separation direction (backward) of the element row by pulling the puller, for example, the slider can be operated even if the hooking shaft hits the closing member and the closing member is pressed backward. The engagement state of the closing member with respect to the trunk can be stably maintained.

In this case, the second engaged portion disposed in the handle attachment portion includes a partition portion disposed along the slider length direction at the center portion in the slider width direction at the free end portion of the handle attachment portion, and the partition portion. And left and right front bulges that bulge from the partition in the slider width direction, and left and right locking restriction portions disposed at the rear end of the partition. Further, left and right accommodation recesses for accommodating the locking claw portions of the closing member are provided between the front bulge portion and the rear end side locking claw portion in the second engaged portion. Thereby, when the closing member is inserted and attached between the upper wing plate of the slider body and the free end portion of the pull handle attaching portion, the closing member can be more securely attached at a predetermined position. Moreover, it can prevent more effectively that the obstruction | occlusion member remove | deviates from a slider trunk | drum and falls off.

Further, the closing member of the present invention includes a left and right inclined wall portion that extends forward from the left and right vertical wall portions, and a dimension in the slider height direction gradually decreases forward, and a central protruding portion that protrudes forward from the central base portion. And have. Furthermore, the accommodation groove part provided in the lower end part of the base part of the closing member and the gap provided between the right and left insertion parts are continuously arranged in the front-rear direction. In this case, the inner wall surfaces of the left and right inclined wall portions in the closing member are formed continuously from the inner wall surfaces of the left and right vertical wall portions. Moreover, the center protrusion part in a closure member has the flat lower surface which contacts the upper surface of a member holding part, and the inclination upper surface which inclines downward toward the front.

Since such a closing member has a shape that is easier to hold with a finger or the like, the closing member can be smoothly attached to the slider body and can be engaged firmly and stably. Further, when the slider of the present invention is slid in the element row separation direction (rearward) by pulling the pull handle, for example, even if the pull handle attachment shaft portion hits the closing member, the pull handle attachment shaft portion is left and right of the closing member. It can be made easy to move upward by the inclined upper surface of the inclined wall portion or the central protruding portion. This makes it difficult for the closing member to be pressed rearward by the attachment shaft portion of the handle, and it is possible to more effectively prevent the closing member from being detached from the slider body.

Particularly in this case, in the side view of the closing member, the central protruding portion of the closing member is provided so as to protrude above the left and right inclined wall portions of the closing member. Thereby, when the attachment shaft portion of the handle is moved rearward and hits the closing member, the attachment shaft portion of the handle can be effectively moved upward toward the free end portion of the handle attachment portion. As a result, since the attachment shaft portion of the handle can be supported by the handle attachment portion of the slider body (particularly, the free end portion of the handle attachment portion), the closing member is made more difficult to be pressed by the attachment shaft portion of the handle. Can do.

Are similarly formed. For this reason, the detailed description regarding these parts will be omitted.

The upper wing plate 11 of the slider body 10 has a thin plate shape having a dimension in the slider height direction (hereinafter abbreviated as a height dimension) of a predetermined size or more. For example, the upper wing plate 11 is notched in the engaged portion formed by being recessed downward from the upper surface of the upper wing plate as in Patent Document 1 or the upper wing plate as in Patent Document 2. The insertion opening to be formed is not provided. Further, the upper surface of the upper wing plate 11 is a smooth flat surface or a slightly curved surface except for a portion where the handle attachment portion 15, the keyhole forming portion 16, and the first engaged portion 20 are arranged. Is formed.

A first engaged portion 20 that engages the lower end portion of the closing member 40 is formed at the rear end portion of the upper blade plate 11 so as to protrude upward from the upper surface of the upper blade plate 11. The first engaged portion 20 has a symmetrical shape with respect to the center position in the slider width direction. Further, the first engaged portion 20 has a maximum value of the dimension in the slider width direction of the first engaged portion 20 (hereinafter abbreviated as a width dimension), for example, as shown in FIG. It is formed to be smaller than the maximum value of the width dimension of the 15 fixed end portions 15 a and further to be smaller than the maximum value of the width dimension of the front connecting column 13.

The first engaged portion 20 of the present embodiment is disposed along the slider length direction on the upper surface of the upper wing plate 11 and holds the closing member 40, and the first engaged portion 20. A member abutting portion 24 that is disposed at the front end portion and abuts the front end portion of the closing member 40, and a member guide portion 25 that extends rearward from the member holding portion 21 along the slider length direction. Have.

The member holding portion 21 of the first engaged portion 20 includes a holding column portion 22 that rises straight upward from the upper blade 11, and left and right protrusions that protrude from the upper end portion of the holding column portion 22 in the slider width direction. The cross section orthogonal to the slider length direction of the member holding | maintenance part 21 exhibits T shape. In this case, the cross section orthogonal to the slider length direction of the member holding portion 21 has a constant shape over the entire slider length direction of the member holding portion 21.

The left and right storage spaces sandwiched between the upper surface of the upper wing plate 11 and the lower surface of the projecting piece 23 are formed on the left and right sides of the holding column 22. In these left and right accommodation spaces in the first engaged portion 20, left and right insertion portions 42, which will be described later, of the closing member 40 are accommodated and held.

In the member holding portion 21 of the present embodiment, the front end position of the member holding portion 21 in the side view of the slider body 10 (FIG. 6) is the front end of the free end portion 15b described later of the pull attachment portion 15 with respect to the slider length direction. (In particular, it is arranged in front of the position L1 of the front end of the second engaged portion 30 of the free end portion 15b). The rear end position of the member holding portion 21 (particularly, the rear end position of the left and right protruding piece portions 23 in the member holding portion 21) is the rear end position of the free end portion 15b of the pull attachment portion 15 with respect to the slider length direction. It is arranged in front of the position L2, preferably in front of a position L3 intermediate between the front end position L1 and the rear end position L2 in the free end portion 15b.

By arranging the front end position of the member holding portion 21 as described above, the closing member 40 is inserted between the upper end plate 11 and the free end portion 15b of the pull attachment portion 15 from the rear side of the slider body 10. When inserted into the gap 19 and engaged with the slider body 10, the left and right insertion portions 42 of the closing member 40 can be firmly held by the member holding portion 21. For this reason, it is possible to prevent the closing member 40 from being tilted so that the left and right insertion portions 42 are lifted from the upper surface of the upper blade 11, and to attach the closing member 40 to the slider body 10 in a predetermined posture. . Furthermore, the state in which the closing member 40 is engaged with the slider body 10 can be stably maintained.

Further, since the rear end position of the member holding portion 21 is disposed forward of the above-described intermediate position L3, the slider height between the first engaged portion 20 and the free end portion 15b of the pull attachment portion 15 is increased. A region where the distance in the vertical direction is limited by the member holding portion 21 can be reduced. For this reason, for example, the member holding portion 21 is formed continuously to the rear opening side edge of the upper blade 11 such that the attachment shaft portion 52 of the handle 50 and the handle insertion gap 19 into which the closing member 40 is inserted. It is possible to ensure a larger size in a wider range in the slider length direction than in the case where the As a result, the attachment shaft portion 52 and the closing member 40 of the handle 50 can be easily and smoothly inserted between the upper blade 11 and the free end portion 15b of the handle attachment portion 15.

Moreover, in the member holding part 21 of this embodiment, the height dimension from the upper surface of the upper blade 11 in the holding column part 22 is set corresponding to the height dimension of the insertion part 42 of the closing member 40. Specifically, the height dimension of the holding column part 22 is set larger than the height dimension of the insertion part 42 of the closing member 40. Moreover, the dimension (width dimension) in the slider width direction of the holding | maintenance pillar part 22 is smaller than the width dimension of the handle attachment part 15, as shown in FIG. Moreover, the width dimension of the holding column part 22 is the same as the width dimension of a partition part 31 (to be described later) of the second engaged part 30 disposed on the free end part 15 b of the pull attachment part 15 or the partition part 31. It is set slightly smaller than the width dimension.

The left and right projecting piece portions 23 in the member holding portion 21 have a height dimension from the upper surface of the upper blade plate 11 to the upper surface of the projecting piece portion 23, from the upper surface of the upper blade plate 11 to the upper end of the holding column portion 22. It is formed in the same size as the height dimension. Each overhanging piece portion 23 is formed such that the height dimension between the upper surface and the lower surface of the overhanging piece portion 23 is smaller than the height dimension from the upper surface of the upper blade 11 in the holding column portion 22. ing. Furthermore, the width dimension from the left edge of the left projecting piece 23 to the right edge of the right projecting piece 23 is smaller than the width dimension of the pull attachment portion 15. Further, the width dimension from the left edge of the left protruding piece 23 to the right edge of the right protruding piece 23 is set to be larger than the width dimension of the holding column portion 22. In this case, the width dimension of each of the left and right projecting piece parts 23 is set to be the same as the width dimension of the holding column part 22 or slightly larger than the width dimension of the holding column part 22. Here, for example, the width dimension of the left projecting piece portion 23 is the dimension in the slider width direction from the left edge of the left projecting piece portion 23 to the boundary position between the left projecting piece portion 23 and the holding column portion 22. To tell.

The member contact portion 24 of the first engaged portion 20 is formed at the front end portion of the first engaged portion 20 and connected to the front end of the member holding portion 21. The member abutting portion 24 is disposed upright from the upper surface of the upper blade 11. Further, the height dimension from the upper surface of the upper blade plate 11 in the member abutting portion 24 is the height dimension from the upper surface of the upper blade plate 11 in the holding column portion 22 of the member holding portion 21 and the upper surface of the upper blade plate 11. To the upper surface of the left and right projecting piece portions 23.

The width dimension of the member abutting portion 24 is set to be larger than the width dimension of the holding column portion 22 of the member holding portion 21, and preferably the right extension from the side edge of the left protruding piece portion 23 in the member holding portion 21. It is set to the same size as the width dimension to the side edge of the piece portion 23.

Furthermore, the front surface of the member abutting portion 24 of the present embodiment is formed as an inclined surface that inclines upward from the upper surface of the upper blade 11 in the side view of the slider body 10 (FIG. 6). As shown in FIG. 2, the inclination angle of the front surface of the member abutting portion 24 with respect to the upper surface of the upper blade plate 11 is the inclination angle of the closing member 40 with respect to the upper surface of the upper blade plate 11 at the inclined upper surface of the central protrusion 47 described later.

Since the front surface of the member abutting portion 24 is inclined as described above, for example, when the slider 1 is slid backward (in the element row separation direction) by pulling the puller 50 of the slider 1, the puller is pulled. 50, the attachment shaft portion 52 of the handle 50 is moved upward along the front surface of the member abutting portion 24 as indicated by a virtual line (two-dot chain line) in FIG. Can be easily guided to the free end portion 15b. This makes it difficult for the closing member 40 engaged with the slider body 10 to be pressed backward by the mounting shaft portion 52 of the handle 50, and as a result, the closing member 40 comes off the slider body 10 and falls off. It can be made difficult to occur.

The member guide portion 25 of the first engaged portion 20 is projected on the top surface of the upper blade 11 and straightly straight along the slider length direction from the member holding portion 21 toward the rear. It is formed as a liner portion extending in the direction. The member guide portion 25 is not provided with the left and right protruding piece portions 23 unlike the member holding portion 21, and is continuously formed rearward from the holding column portion 22 of the member holding portion 21. The width dimension of the member guide part 25 is set to the same size as the width dimension of the holding column part 22 of the member holding part 21. In particular, the member guide portion 25 of the present embodiment is formed with a certain width dimension from the upper surface of the upper blade 11 to a predetermined height position, and more than the predetermined height position in the member guide portion 25. The upper part is formed by gradually decreasing the width dimension.

The front end portions of the left and right locking claws 44 have a shape in which the cross section perpendicular to the slider height direction has a substantially triangular shape so that the width dimension gradually decreases toward the front. Inner wall surfaces arranged at the front end portions of the left and right locking claws 44 are inclined to the outside toward the front with respect to the slider length direction.

Since the front end portion of the locking claw portion 44 is formed in the shape as described above, when the closing member 40 is inserted into the handle insertion gap 19 from the rear of the slider body 10, the front end portion of the locking claw portion 44 is By making sliding contact with the locking restriction portion 33 of the second engaged portion 30, it is possible to effectively promote elastic deformation of the vertical wall portion 43 so that the left and right vertical wall portions 43 of the closing member 40 open outward. it can.

More specifically, when the closing member 40 is inserted, the substantially triangular front end portion of the locking claw portion 44 is the rear inclined surface of the locking regulating portion 33 in the second engaged portion 30 of the slider body 10. By making contact with and slidingly contact, the left and right vertical wall portions 43 of the closing member 40 can be elastically deformed so as to spread outward. As a result, the left and right latching claw portions 44 of the closing member 40 are smoothly passed over the latching regulation portion 33 of the second engaged portion 30, and as shown in FIG. That is, it is received in the receiving recess 34 of the second engaged portion 30, and the locking surfaces of the left and right locking claws 44 are brought into contact with the front locking surface of the locking regulating portion 33. Can be touched. Further, when the left and right engaging claws 44 of the closing member 40 are engaged with the left and right engaging restricting portions 33 of the second engaged portion 30, a substantially triangular front end portion of the engaging claw 44. Can be brought into contact with the front bulging portion 32 of the second engaged portion 30. Thereby, the closing member 40 can be stably stopped at a predetermined position.

Further, in the closing member 40 of the present embodiment, when the closing member 40 is attached to the slider body 10, the left and right locking claw portions 44 are housed in the housing recesses 34 of the second engaged portion 30 and are closed. The front end portions of the left and right insertion portions 42 of the member 40 are in contact with the member contact portion 24 of the first engaged portion 20 of the slider body 10. Thereby, the movement of the closing member 40 in the slider length direction is restricted. As a result, the closing member 40 is completely fixed so as not to move with respect to the slider body 10, and is stably attached to a predetermined position in the slider length direction.

The left and right inclined wall portions 45 in the closing member 40 are formed continuously from the left and right vertical wall portions 43 toward the front. That is, the inner wall surface and the outer wall surface of the inclined wall portion 45 are continuously formed so as to form a plane from the inner wall surface and the outer wall surface of the left and right vertical wall portions 43, respectively. Further, the left and right inclined wall portions 45 are respectively provided on the outer side edge portions of the left and right insertion portions 42. Further, the inclined wall portion 45 is formed such that the upper surface of the inclined wall portion 45 is inclined downward toward the front so that the height dimension is gradually reduced toward the front. Further, the front end edges of the left and right inclined wall portions 45 are arranged at the same position as the front end edges of the left and right insertion portions 42 in the slider length direction.

By providing such left and right inclined wall portions 45, the dimension of the closing member 40 in the slider length direction can be increased, and the closing member 40 can be formed in a shape that can be easily picked from the left and right by a finger or the like. Further, the left and right inclined wall portions 45 can cover the member holding portion 21 disposed on the first engaged portion 20 of the slider body 10 from the left and right outer sides and make it difficult to see from the outside. For this reason, the appearance quality of the slider 1 can be improved.

The central base portion 46 in the closing member 40 is erected upward from the base portion 41 and is disposed between the left and right vertical wall portions 43. Further, the outer surface of the center base portion 46 and the left and right vertical wall portions 43 are separated from each other, and a gap that allows elastic deformation of the vertical wall portion 43 is formed. For example, as shown in FIG. 11, the height position of the upper surface of the central base portion 46 is set lower than the height positions of the lower surfaces of the left and right engaging claws 44. The upper surface is formed in a concave surface shape such that a central portion in the slider width direction is recessed along the slider length direction.

By providing such a central base portion 46, the central protruding portion 47 of the closing member 40 can be stably formed, and the strength of the central protruding portion 47 can be ensured appropriately. Further, even when the center base portion 46 receives an external force that pushes the pull handle attachment portion 15 of the slider body 10 downward, for example, the free end portion of the pull handle attachment portion 15 at the center base portion 46 of the closing member 40. Since it becomes possible to support 15b, it can suppress that the handle attachment part 15 deform | transforms. Furthermore, since the central base portion 46 is arranged, it is possible to prevent foreign matter from entering and sandwiching between the left and right vertical wall portions 43 of the closing member 40.

The central protruding portion 47 of the closing member 40 extends forward from the central base portion 46. In this case, the front end edge of the central projecting portion 47 is arranged at the same position as the front end edges of the left and right insertion portions 42 and the front end edges of the left and right inclined wall portions 45 in the slider length direction, as shown in FIG. . The central protrusion 47 of the present embodiment has a base end portion having a constant height dimension and a tip end portion that gradually decreases the height dimension toward the front.

In this case, the lower end surface at the proximal end portion of the central projecting portion 47 and the lower end surface at the distal end portion are formed on a single plane orthogonal to the slider height direction. Further, the lower end surface of the front end portion of the central projecting portion 47 is formed so as to come into contact with the upper surface of the member holding portion 21 of the first engaged portion 20 when the closing member 40 is attached to the slider body 10. As a result, as shown in FIG. 4, the left and right projecting piece portions 23 of the first engaged portion 20 of the slider body 10 are sandwiched between the left and right insertion portions 42 and the central projecting portion 47 of the closing member 40. Can be supported.
Similar to the upper surface of the central base portion 46, the upper surface of the base end portion of the central projecting portion 47 is formed in a concave surface shape such that the central portion in the slider width direction is recessed along the slider length direction.

The upper surface of the tip of the central protrusion 47 is formed as an inclined upper surface that is inclined downward toward the front. In this case, the inclination angle with respect to the upper surface of the upper blade plate 11 at the inclined upper surface of the central protrusion 47 is set to the same magnitude as the inclination angle with respect to the upper surface of the upper blade plate 11 at the upper surface of the inclined wall portion 45. It is set to be smaller than the inclination angle with respect to the upper surface of the upper blade 11 at the front surface of the member contact portion 24 in the engaged portion 20. Furthermore, in the present embodiment, the central protruding portion 47 is disposed so as to protrude above the left and right inclined wall portions 45 in a side view of the closing member 40 (FIG. 13).

By forming the inclined upper surface of the central projecting portion 47 as described above, for example, when the pulling handle 50 is pulled rearward and the mounting shaft portion 52 hits the closing member 40, the mounting shaft portion 52 of the pulling handle 50 is attached to the pulling handle. It can be guided upward along the inclined upper surface of the central projecting portion 47 toward the free end portion 15b of the portion 15, and can be brought into contact with the free end portion 15b (see FIG. 2). As a result, the attachment shaft portion 52 of the handle 50 can be supported by the free end portion 15b of the handle attachment portion 15. As a result, the attachment shaft portion 52 contacts the closing member 40 in the direction in which the handle 50 is strongly pulled. This makes it difficult to press the closing member 40 backward by the mounting shaft portion 52 of the handle 50.

Next, a method for assembling the slider 1 according to the present embodiment using the slider body 10, the handle 50, and the closing member 40 described above will be described.
First, the work of attaching and holding the handle 50 to the handle attaching portion 15 of the slider body 10 is performed. Specifically, the attachment shaft portion 52 of the handle 50 is inserted into the handle insertion gap 19 disposed between the upper surface of the upper blade 11 and the free end portion 15b of the handle attachment portion 15 from the rear side of the slider body 10. insert.

It is arranged ahead of an intermediate position L3 between the front end position L1 and the rear end position L2. Further, the member guide portion 25 of the first engaged portion 20 is disposed with a height dimension smaller than that of the member holding portion 21.

Thereby, even if the 1st to-be-engaged part 20 protrudes on the upper surface of the upper blade 11, the height of the space | interval between the free end part 15b of the handle attachment part 15 and the 1st to-be-engaged part 20 is provided. Dimensions are secured appropriately. Therefore, the attachment shaft portion 52 of the pull handle 50 can be smoothly inserted into the pull handle insertion gap 19, and the attachment shaft portion 52 of the pull handle 50 is connected to the attachment main body portion 15 c of the pull attachment portion 15 via the pull handle insertion gap 19. It can be smoothly moved to the space between the blade plate 11 and accommodated and held in the space.

Next, an operation of assembling the closing member 40 to the slider body 10 holding the handle 50 is performed. In this operation, as shown in FIG. 14, the closing member 40 is inserted from the rear side of the slider body 10 between the upper surface of the upper blade 11 and the free end portion 15 b of the handle attachment portion 15. At this time, the closing member 40 is inserted so that the base portion 41 of the closing member 40 is placed on the upper surface of the upper blade 11, and the first engaged portion 20 is inserted between the left and right insertion portions 42 of the closing member 40. The member guide portion 25 is inserted.

Subsequently, the closing member 40 is pushed forward along the slider length direction. At this time, by inserting the member guide portion 25 of the first engaged portion 20 into the gap between the left and right insertion portions 42 of the closing member 40 and the housing concave groove portion 48 of the base portion 41 in order, the closing member 40 is Advancing stably along the member guide portion 25 is possible. Accordingly, the left and right insertion portions 42 of the closing member 40 are inserted between the left and right projecting piece portions 23 of the member holding portion 21 of the first engaged portion 20 and the upper blade 11, and the closing member 40 is also inserted. The left and right locking claws 44 can be brought into contact with the locking restricting portion 33 of the second engaged portion 30.

Further, when the closing member 40 is pushed forward, the left and right locking claws 44 of the closing member 40 are brought into sliding contact with the locking restriction portion 33 of the second engaged portion 30. Thereby, as described above, the left and right vertical wall portions 43 of the closing member 40 are elastically deformed so as to expand toward the outside in the slider width direction while the closing member 40 moves forward, and between the left and right locking claws 44. The interval can be increased.

As the closing member 40 advances, the left and right locking claws 44 of the closing member 40 move forward relative to the locking restriction portion 33 of the second engaged portion 30, so that the left and right vertical wall portions 43 are moved. While returning to elasticity, the left and right engaging claws 44 are accommodated in the accommodating recess 34 of the second engaged portion 30. As a result, the closing member 40 is locked to the locking restriction portion 33 of the second engaged portion 30. At the same time, the left and right insertion portions 42 of the closing member 40 come into contact with the member contact portion 24 of the first engaged portion 20.

Therefore, the operation of attaching the handle 50 to the slider body 10 and the operation of attaching the closing member 40 to the slider body 10 can be performed smoothly and relatively easily.

Moreover, in the slider 1 of the present embodiment, as shown in FIG. 2, the front surface of the member abutting portion 24 in the first engaged portion 20 of the slider body 10 is formed to be inclined upward. At the same time, the inclined upper surface of the central projecting portion 47 of the closing member 40 is formed to be inclined upward toward the rear. As a result, when the slider 50 is slid backward (in the element row separation direction) by pulling the handle 50 as described above, the attachment shaft portion 52 of the handle 50 is brought into contact with the member of the first engaged portion 20. The front surface of the portion 24 and the inclined upper surface of the central projecting portion 47 of the closing member 40 can be easily guided to the free end portion 15 b of the pull attachment portion 15.

As a result, the attachment shaft portion 52 of the pull handle 50 is stably supported by the pull attachment portion 15 that is firmly formed. At the same time, the closing member 40 attached to the slider body 10 can be made difficult to be pressed rearward by the attachment shaft portion 52 of the handle 50. Therefore, the engagement state of the closing member 40 with respect to the slider body 10 is stably maintained, and it is difficult to cause the closing member 40 to be detached from the slider body 10 due to the operation of the handle 50.

Particularly in this embodiment, the inclination angle of the front surface of the member contact portion 24 and the inclination angle of the inclined upper surface of the central projecting portion 47 of the closing member 40 are different. Further, the inclination angle of the inclined upper surface of the central protrusion 47 with respect to the upper surface of the upper blade 11 is made smaller than the inclination angle of the front surface of the member contact portion 24. Thereby, the space part which can hold | maintain the attachment shaft part 52 of the handle 50 in front of the free end part 15b of the handle attachment part 15 is appropriately securable. At the same time, the attachment shaft portion 52 of the handle 50 can be easily guided toward the free end portion 15b of the handle attachment portion 15 by the above-described upward inclined surface.

In the slider 1 according to the above-described embodiment, the left and right insertion portions 42 of the closing member 40 are inserted between the upper blade 11 of the slider body 10 and the projecting piece portion 23 of the

member holding portion
