Description

  The present invention relates to a structure of a connecting tool for reliably and simply performing an operation for connecting one end side of an open fastener.

  An open fastener used for this type of blouson is basically provided with a stringer, an element, and a slider, and an upper stopper member for stopping the slider is formed at one end in a direction along the element of both stringers. The other end is formed with a box having a socket hole and a pin engageable with the socket hole of the box in order to stop the slider and to openly connect the fastener (see Patent Document 1).

On the other hand, in recent years, an open fastener opening / closing insert intended to be easily operated even by a child or a handicapped person has been disclosed (see Patent Document 2). An outline of such an open fastener open / close insertion tool is as follows. The upper part of the coupler is rotated by snap-joining the coupler and the locking tool to the front and back surfaces of the slide fastener so as to be rotatable in the horizontal direction. This is a horizontal insertion type opening and closing insert that is moved and fitted into a socket hole that opens to the side of the locking portion. And in this separation fitting insertion tool, for example, the separation prevention which consists of the latching protrusion provided in the lower end of the horizontal insertion fitting part of a coupler, and the projection provided in the outer peripheral wall of the lower end of a locking tool By having the mechanism, it is ensured that the coupler rotated to the position where the slider can be pulled up is not separated in the horizontal direction.

  However, the conventional open fastener structure described in Patent Document 1 has the following problems.

  That is, in order to connect the ends of the separated stringers, after inserting the pin into the socket hole of the box through the slider to a predetermined depth while the slider is in contact with the box, the inserted state at this predetermined depth The operation of closing the open fastener is necessary by pulling the slider to the top stopper member side while maintaining the above. Therefore, if the insertion depth of the pin into the box is insufficient or the slider has moved away from the box, it will not be lifted even if the slider is pulled up, or the element will be lifted with the elements not properly engaged. End up.

  For this reason, a relatively accurate operation is required in which the pin must be surely inserted into the socket hole through the slider to a predetermined depth while maintaining the state where the box and the slider are in contact with each other. Such a detailed operation is extremely difficult for a person whose hand is not dexterous, a handicapped person, an elderly person with poor vision, or the like.

  In this regard, in the structure of the open fastener opening / closing insertion tool described in Patent Document 2, a separation preventing mechanism is provided that prevents the coupling tool rotated to a position where the slider can be pulled up from separating horizontally. Therefore, while holding down one stringer, rotate the stringer with the other coupling piece attached, and fit it in the horizontal groove of the slider attached to the locking piece, so that the coupling piece and the locking piece will not open In this way, it is not necessary to engage and close the open fastener by stepping up the slider with the other hand while keeping both stringers in contact with each other. .

  However, in the opening / closing insertion tool of the open fastener described in the above-mentioned Patent Document 2, in order to prevent the elastic leg portion from being easily removed from the hole except when necessary, each of the coupling tool, the locking tool, etc. The form of the parts is complicated, and there is a problem that the cost of the mold for manufacturing these parts is high and the product cost is relatively increased.

  In addition, since the number of parts is relatively large compared to conventional open fasteners, the manufacturing process of the entire open fastener is complicated, resulting in an increase in the cost of the product, and the open fasteners are fragile and cannot be repaired. In such a case, there is a disadvantage that the clothes themselves using the fastener must be discarded.

  Furthermore, in Patent Document 2, the stringer attached with the other coupling piece is rotated and fitted into the lateral groove of the slider attached to the locking piece, but the operation for this fitting is completed. Since there is no way of confirming this, there is a problem that it is difficult to attach an operation stick.

  Accordingly, the present invention provides a connecting tool for an open fastener capable of ensuring and simplifying the connecting operation of the open fastener, and confirming that the connecting operation is completed, with a relatively simple structure. The purpose is to do.

The connecting device for an open fastener according to the present invention is attached to a longitudinal end portion of one stringer, and is attached to a first member having an insertion portion and a longitudinal end portion of the other stringer. And a second member in which a socket hole into which the insertion part of the member can be inserted is formed, and the first member extends along the thickness direction of the one stringer on the terminal end side of the insertion part. A protruding protrusion, and a protruding portion extending along a longitudinal direction of the one stringer and continuous with a base side of the protruding portion, and the protruding portion is terminated with respect to a short direction of the one stringer. the side extends obliquely toward the opposite side, the second member forms a diameter socket hole into which the projecting portion on the end side of the socket holes having an insertion opening capable, the diameter Socket hole The side surface on the terminal end side of the other stringer extends obliquely toward the side opposite to the terminal end side with respect to the short direction of the other stringer . both when the Ru facing surfaces can abut der an opening, the inner portion of the protruding portion and the enlarged diameter socket hole and, the opening of the protrusion when the protrusion is inserted through the opening Each of the protrusions and the engagement means formed in the inner portion of the diameter-enlarged socket hole in the short direction of the stringer. The first member and the first member are inserted by inserting the insertion portion and the projection portion into the diameter-expanded socket hole from the opening portion until the engagement means are engaged with each other. Position between two members And performing the eyes and the first member and the connection between the second member at the same time (claim 1). As the structure of the engaging means, a step is formed in the protrusion of the first member, and a protrusion is formed in the vicinity of the periphery of the opening in the inner portion of the enlarged diameter socket hole. It can be considered that the projecting portion has a spring structure by forming a crack. Further, as the protrusion, a protrusion is formed in the vicinity of the periphery of the opening in the inner portion of the enlarged diameter socket hole, the protrusion protrudes linearly, and the protrusion is related to the protrusion. A hook-like shape can be considered.

  Thereby, the engaging means (projecting part) of the first member and the engaging means (projecting part) formed in the inner portion of the diameter-enlarged socket hole of the second member are mutually connected along the short direction of the stringer. The engaging portion (protruding portion) is inserted into the enlarged diameter socket hole from the opening portion by engaging the insertion portion and the protruding portion of the first member with the socket hole and the socket of the second member. By inserting until it engages at the (protruding part), the insertion part is inserted deeply into the socket hole along the short direction of the stringer, and at the same time, the insertion part is deeply inserted into the socket hole along the longitudinal direction of the stringer. Inserted. Moreover, when engaging with the engaging means (protruding part) of the first member and the engaging means (protruding part) formed on the inner portion of the diameter-enlarged socket hole, an engagement sound or feel is generated. Confirm that the operation is complete with the sound and feel.

The open fastener connecting tool according to claim 1, wherein the holding member of the first member and the holding member and the abutting portion of the second member form a slider storage portion and the other stringer A locking piece may be formed in the vicinity of the second member (claim 2). Thus, the slider is temporarily engaged with the locking piece, and the upward movement of the slider in the stringer longitudinal direction is restricted.

As described above, according to the first and second aspects of the present invention, the engaging means (projecting portion) of the first member and the engaging means formed on the inner portion of the socket of the second member are provided. operation only to bind in close proximity to each other along the transverse direction of the stringer, it is possible to connect the both first and second members, and, between the first member and the second member It is possible to perform the positioning between the first member and the second member at the same time, and it is possible to ensure and simplify the fastener connecting operation regardless of who operates.

  Further, the engaging means (protruding part) of the first member and the engaging means (protruding part) formed on the inner part of the socket of the second member are brought close to each other along the short direction of the stringer, The insertion part and the protrusion of the first member are inserted into the socket hole and the diameter-enlarged socket hole of the second member, and the engaging means (protrusion part) is inserted into the diameter-enlarged socket hole from the opening part. The insertion part is inserted deeply along the short direction of the stringer into the socket hole at the same time as the insertion part is inserted deeply along the longitudinal direction of the stringer into the socket hole. Therefore, it is possible to simultaneously perform positioning between the first member and the second member and connection between the first member and the second member. Moreover, when engaging with the engaging means (protruding part) of the first member and the engaging means (protruding part) formed on the inner portion of the diameter-enlarged socket hole, an engagement sound or feel is generated. The end of the connecting operation can be surely confirmed by its sound and feel, and it is possible to add an operation delay.

  According to the second aspect of the present invention, the slider is temporarily engaged with the locking piece and the upward movement of the stringer in the longitudinal direction is restricted for an arbitrary period. Inconvenience that the slider moves upward during the operation of connecting the first member and the second member using the engaging means formed at the protrusion and the inner part of the opening of the second member. Can be eliminated.

  Embodiments of the present invention will be described below with reference to the drawings.

  1 to 5 show a first embodiment of the present invention. An open fastener (also referred to as an open slide fastener) 1 in which the present invention is used includes a pair of stringers 2 and 3, a plurality of elements 4 attached along opposite inner edges of the stringers 2 and 3, and the element 4 Upper end stop members 5 and 6 attached to one end side of the member and a slider 7 for engaging or opening the opposing elements 4 with each other.

  Among these, the stringers 2 and 3 are obtained by sewing a cord (striped braid) for sewing the element 4 at the end, and for example, a polyester tape or the like is used as a material. The element 4 is sewn precisely and firmly to the stringers 2 and 3 so as to be equidistant with a predetermined width, and is made of metal or plastic. The element 4 is also referred to as a tooth, and the shape of the meshing portion is substantially T-shaped in this embodiment, but is not necessarily limited thereto. The top stopper members 5 and 6 are for stopping the movement of the slider 7 on the upper end side of the fastener 1.

  The slider 7 is basically composed of a body 8 and a puller 9. Among these, the body 8 is not particularly shown, but its width becomes narrower from the front end side toward the rear end side and its side edge. Plate-like upper and lower surface portions having flanges extending opposite to each other, and a connecting column that connects the upper surface and the lower surface portion on the tip side. A stopper for preventing the slider 7 from being inadvertently pulled down may be provided on the rear end side of the slider 7.

  A first bottom stop member 10 and a second bottom stop member 16 are attached to the end side of the element 4 opposite to the top stop members 5 and 6 of the stringers 2 and 3. The first bottom stop member 10 is fixed to the end portion of the stringer 2 and basically includes a plate portion 11 and an insertion portion 12 having the same function as a conventional pin portion. In this embodiment, a part of the first bottom stop member 10 protrudes on the opposite side to the end of the stringer 2, and the element 4 located at the end of the element 4 is formed on the inner edge of the protrusion. Has been.

  Further, the hook member 10 is attached to the plate portion 11 as an engaging means for the first bottom member 10 with the second bottom member 16. However, a hook male body may be attached instead of the hook female body 13 although not shown. The first stop member 10 moves toward the lower end side of the plate portion 11 in the direction of the upper stop member 5 and a moving mechanism that applies a moving force to the first member 10 and the first stop member 10. A protrusion 14 is formed as a defense mechanism for restricting the above. In this embodiment, the protrusion 14 has a rectangular parallelepiped shape in which each side surface stands upright in a substantially vertical direction with respect to the surface of the plate portion 11 as shown in FIG.

  Furthermore, the insertion portion 12 of the first bottom stop member 10 has a thickness that can be inserted into a socket hole 19 of the second bottom stop member 16 described later, and an end portion of the insertion portion 12 includes a plate portion. Two locking pieces 15 and 15 extending obliquely toward the side 11 are integrally formed. These locking pieces 15 have the flexibility to buckle to the surface side of the insertion portion 12 when a predetermined pressure is applied from the outside. However, the shape of the locking piece 15 is not limited to this, but although not shown, the locking piece 15 may be formed only on one side of the insertion portion 12 instead of on both sides. Furthermore, any locking mechanism that can temporarily lock the insertion portion 12 in the socket hole 19 of the box portion 17 may be used.

  The second bottom stop member 16 is fixed to the end portion of the stringer 3, and includes a box portion 17 and a plate-like overhang portion that projects from the end portion of the box portion 17 along the short direction of the stringer 3. 18 is basically configured. In the box portion 17, a socket hole 19 into which the insertion portion 12 of the first bottom stop member 10 is inserted opens sideways. As shown in FIG. 1B, FIG. 3, etc., the socket hole 19 is formed with the opening peripheral portions 20 and 20 in the vicinity of the opening. The inner width is about the thickness, and the interior following this has an inner width from one locking piece 15 to the other locking piece 15 of the insertion portion 12. Further, in the box portion 17, in order to eliminate the movement in the short direction of the stringers 2 and 3 of the slider 7 that is maintained at a position in contact with the upper end of the box portion 17, the guide projection portion 21 has the longitudinal direction of the stringer 3. It extends along the direction.

  In this embodiment, the overhanging portion 18 is temporarily lifted upward from the end of the box portion 17 and then extends horizontally. In this horizontal portion, the elements 4, 4 are in positions where the elements 4 and 4 are properly meshed with each other. A hook male body 22 for appropriately engaging with the hook female body 13 of the one stop member 10 is attached. However, when a hook male body is attached to the first bottom stop member 10, a hook female body is attached.

  The second bottom stop member 16 has a projection 23 formed at the boundary portion with the box portion 17 on the back surface side of the overhang portion 18. The protrusion 23 is provided at a position where it abuts against the protrusion 14 of the first bottom stop member 10 when the female body 13 and the male body 22 of the hook are engaged. Is a substantially trapezoidal shape having an inclined surface 23a with the projecting portion 14 side notched so that it can be abutted not on its top surface but on its side surface. However, the protrusion 14 may have a substantially trapezoidal shape, and the protrusion 23 may have a substantially rectangular parallelepiped shape.

  The connection process of the open fastener 1 using the 1st bottom stop member 10 and the 2nd bottom stop member 16 of the said structure is demonstrated below.

  After the user of the open fastener finds the position of the female body 13 of the hook of the first bottom stop member 10 and the male body 22 of the second bottom stop member 16 by the unevenness, the female of the hook The female body 13 and the male body 22 are engaged from the state where the body 13 and the male body 22 are in contact with each other. Accordingly, the insertion portion 12 of the first bottom stop member 10 is determined by the relative movement amount between the first bottom stop member 10 and the second bottom stop member 16 when the female body 13 is press-fitted into the male body 22. Is inserted deeply into the socket hole 19 of the second bottom stop member 16. When the insertion portion 12 is inserted, the locking piece 15 is pressed by the opening peripheral portions 20 and 20 located at the opening end of the socket hole 19 as shown in FIGS. After buckling in the short direction of the insertion part 12, the original state is restored in the socket hole 19, so that it is engaged in the socket hole 19 with a certain and required strength. Thereby, even if the engagement state between the female body 13 and the male body 22 of the hook is erroneously released, the first bottom stop member 10 and the second bottom stop member 16 are not detached.

  When the female body 13 and male body 22 of the hook are engaged, the protrusion 14 of the first bottom stop member 10 and the protrusion 23 of the second bottom stop member 16 abut, As shown in 4 (a), the protrusion 14 abuts on the midway portion of the inclined surface 23 a of the protrusion 23. For this reason, as shown in FIG. 4B, the protrusion 14 and the protrusion 23 are relatively aligned along the longitudinal direction of the stringers 2 and 3 (the direction of the arrow (1) in FIG. 4B). Sneak away. However, since the male body 22 and the female body 13 of the hook are engaged with each other so as to be able to rotate to some extent, the second bottom stop member 16 rotates around the center M of the socket as shown in FIG. The movement is in the direction of the arrow (2) with the center, and the first bottom stop member 10 is in the direction of the arrow (3) with the center N of the socket as the center of rotation. However, the stringer 2 moves to the socket hole 19 of the box body 17 of the second bottom stop member 16 to the appropriate depth to the longitudinal end side of the stringer 3 and is pulled up. Since the protrusion 14 is restrained by the protrusion 23, the stringer 2 is braked in this pulling direction.

  As described above, the pin portion (in this application, the insertion portion is inserted into the socket hole 19 through the slider 7 as in the conventional open fastener while maintaining the state where the box portion 17 and the slider 7 are in contact with each other while having a relatively simple configuration. Since the stringer 2 is held at a position where it can be lifted while properly engaging the elements 4 and 4 without having to perform an operation for securely inserting 12) to a predetermined depth, the user holds around the binding site. On the other hand, since it is only necessary to pull up the slider 7 and pull it up, the manufacturing cost and the operability are excellent.

  But the structure of the 1st bottom stop member 10 and the 2nd bottom stop member 16 is not limited to what was mentioned above, For example, the box part 17 and the overhang | projection part 18 which comprise the 2nd bottom stop member 16 are integrated. Instead of forming the two, they may be formed as two independent parts and then joined appropriately. Further, the engaging means and the moving mechanism for the first bottom stop member 10 and the second bottom stop member 16 are not limited to the above-described configuration.

  A second embodiment different from the above-described embodiment will be described below with reference to FIGS. However, the same configurations and operational effects as those of the previous embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The first bottom stop member 10 has a lever 24 and a rotation axis extending along the longitudinal direction of the stringer 2 in the direction of the second bottom stop member 16 (that is, the short direction of the stringer 2). The base 25 is attached to the plate portion 11 so as to be integrated therewith. In the first bottom stop member 10, a protrusion 14 is formed on a portion of the upper surface of the plate portion 11 on the end side with respect to the lever 24. As shown in FIG. 6 and FIGS. 8B and 8C, the protruding portion 14 has a side surface opposite to the end portion in the longitudinal direction of the stringer 2 from the inside to the outside in the short direction of the stringer 2. Accordingly, the inclined surface 14b is formed so that the width of the protruding portion 14 increases.

  In the second bottom stop member 16, a through hole 26 into which the lever 24 can be inserted is formed in the overhanging portion 18, and the first bottom stop member 10 side of the through hole 26 extends from the surface of the overhang portion 18. A protruding protrusion 27 is formed. The side surface of the protrusion 27 that is in contact with the peripheral edge of the through hole 26 is erected substantially vertically from the inner peripheral surface of the through hole 26. In addition, the second locking member 16 is formed with a recess 28 that is attached when the lever 24 rotates and is connected to the through hole 26 along the longitudinal direction of the stringer 3.

  Further, the second locking member 16 has a projection 23 formed on the back side of the plate portion 11, and this projection 23 is opposed to the projection 14 of the first bottom stop member 10 and the stringer 2. 3 are shifted in the longitudinal direction. As shown in FIGS. 6 and 8B and 8C, the protrusion 23 has a side surface on the end side in the longitudinal direction of the stringer 3 extending from the inside to the outside along the short direction of the stringer 3. An inclined surface 23a is formed so that the width of the protruding portion 23 increases as it goes.

  A connection process of the open fastener 1 using the first bottom stop member 10 and the second bottom stop member 16 having the above configuration will be described below with reference to FIG.

  First, as shown in FIG. 8 (a), the lever 24 of the first bottom stop member 10 is inserted into the through hole 26 of the second bottom stop member 16, and the lever 24 is moved to FIG. 8 (b). Stand up as shown. Thereby, the inclined surface 14b of the protrusion part 14 and the inclined surface 23a of the protrusion part 23 will be in the state contact | connected by the dimension of L1. Next, the lever 24 is rotated in the direction of the arrow (4) in FIG. Thereby, when the tail part of the lever 24 rotates from the inside of the through hole 26 to the projecting part 27 side of the overhanging part 18, the projecting part 27 is pressed, and the direction of the arrow (5) in FIG. The second bottom stop member 16 is moved in a direction in which the inclined surface 14b of the portion 14 and the inclined surface 23a of the protrusion 23 are narrowed from L1 to L2. However, the first bottom stop member 16 moves relative to the second bottom stop member 16 in the opposite direction, and the insertion portion 12 is inserted into the socket hole 19 to an appropriate depth.

  Then, due to the movement of the second bottom stop member 16 in the direction indicated by the arrow (5), the protruding portion 23 and the protruding portion 14 move toward each other, but both of them are inclined surfaces that are temporarily inclined in the opposite direction. 23a and the inclined surface 14b move while abutting on each other, so that a force to move also in the direction of the arrow (6) is applied to the first bottom stop member 10. As a result, the stringer 2 is moved and drawn to an appropriate depth toward the end in the longitudinal direction of the stringer 3 with respect to the socket hole 19 of the box body 17 of the second bottom stop member 16.

  Therefore, in this embodiment, the pin portion is inserted into the socket hole 19 through the slider 7 while maintaining a state in which the box portion 17 and the slider 7 are in contact with each other while maintaining a relatively simple configuration. The stringer 2 is held in a position where it can be pulled up while properly engaging the elements 4 and 4 without the need to insert the insertion portion 12 (in this application, the insertion portion 12) to a predetermined depth. Since it is only necessary to pull up the slider 7 while holding around the part, the manufacturing cost and the operability are excellent.

  A third embodiment different from the above-described two embodiments will be described below with reference to FIGS. However, the same configurations and operational effects as those of the previous two embodiments are denoted by the same reference numerals, and the description thereof is omitted.

  As shown in FIG. 9, the first bottom stop member 10 includes a relatively thin flat-plate-like insertion portion 12 having an element 4 formed on the upper side, and an open-side end serving as an anti-element 4 of the insertion portion 12. It has as a thing integrally formed with the protrusion part 30 which protruded in the both sides of the said insertion part 12 along the thickness direction with respect to this insertion part 12 in the site | part. The slider 7 is basically composed of a body 8 and a puller 9. Among these, the body 8 is not particularly shown, but its width becomes narrower as it goes from the front end side to the rear end side. It is comprised by the plate-shaped upper surface part and lower surface part which have a flange extended facing a side edge, and the connection pillar which connects this upper surface and lower surface part by the front end side. The slider 7 is provided with a stopper at its rear end side to prevent the slider 7 from being pulled down carelessly, while the insertion portion 12 is inserted into the body 8 of the slider 7. It is preferable to adopt a structure in which braking is released when the stopper is flexed or compressed.

  In this embodiment, the protrusion 30 has a rectangular parallelepiped shape, and a step is formed in the middle of the protrusion 30 to form the head 30a and the stringer 2 with respect to the head 30a as shown in FIG. The bridge-like portion 30b has a relatively narrow width when viewed from below. Further, the protrusion 30 does not extend horizontally with respect to the short direction of the stringer 2 but extends slightly obliquely upward, so that it faces the second bottom stop member 16 of the head 30a. The surface to be inclined is also inclined, and the lower end side thereof is slightly protruded from the ends of the stringer 2 and the insertion portion 12.

  Further, the first bottom stop member 10 has a raised portion 31 that extends along the longitudinal direction of the stringer 2 and is integrally formed with the protruding portion 30 and the like at the side edge on the anti-stringer 3 side. As shown in FIGS. 9B and 9C, the raised portion 31 is raised on at least one side (in this embodiment, both sides) along the thickness direction of the insertion portion 12. Thus, the width of the bulge is larger than the width of the protrusion 30. The raised portion 31 is substantially in contact with the surface of the body 8 when the slider 7 is lowered to the lowermost position, so that the protruding portion 30 and the holding piece 31a constituting a part of the slider storage portion 36 are provided. The box part 17 of the second bottom stop member 16 has a shape having a surface 31b in contact with the peripheral surface of the socket holes 19, 38. The surface 31 b is inclined at a predetermined angle α (for example, 8 degrees) with respect to the longitudinal direction of the stringer 2.

  Note that the first bottom stop member 10 may be provided with a handle 32 that is thin but has a certain degree of strength, extending from the raised portion 31 to the opposite side of the protruding portion 30. The handle 32 is also formed integrally with the raised portion 31 of the first bottom stop member 10 or the like.

  As shown in FIG. 10, the second bottom stop member 16 includes a holding piece 35 that forms a slider storage portion 36 together with a holding piece 31 a of the first bottom stop member 10, a contact portion 34, and the holding piece 35. And a substantially rectangular parallelepiped box portion 17 formed integrally with the abutting portion 34. The box portion 17 has a side surface that faces the first bottom stop member 10 and contacts the raised portion 31 when connected. The side surface of the box portion 17 is inclined at a predetermined angle α (for example, 8 degrees) with respect to the longitudinal direction of the stringer 3. Then, on the side surface of the box portion 17, a socket hole 19 into which the insertion portion 12 of the first bottom stop member 10 is inserted, and a protruding portion of the first bottom stop member 10 in the open end direction of the socket hole 19. An enlarged socket hole 38 into which 30 is inserted is formed continuously. That is, the diameter-expanded socket hole 38 has a width in the short direction of the opening that is larger than a width in the short direction of the opening of the socket hole 19.

  In this embodiment, the diameter-expanded socket hole 38 is a bent protrusion 39 having a depression on the opposite side to the opening, as shown in FIGS. 10 (b) and 11 (b), in the vicinity of the opening. Is formed. As shown in FIG. 10B, the protrusion 39 is split into a plurality along the protrusion direction, thereby providing the protrusion 39 with flexibility and a spring structure as a socket part. Yes.

  And the 2nd bottom stop member 16 has the overhang | projection part 40 which protruded from the open side termination | terminus vicinity site | part of the diameter expansion socket hole 38, as shown to Fig.10 (a). As a result, the user can easily find the fixed position of the diameter-expanded socket hole 38 even by searching, and positioning is facilitated.

  The connection process of the open fastener 1 using the 1st bottom stop member 10 and the 2nd bottom stop member 16 of the said structure is demonstrated below.

First, the slider 7 is pulled down until it abuts against the abutting portion 34 that constitutes the slider accommodating portion 36 of the second bottom stop member 16. In this case, as shown in FIGS. 10 (a) and 11 (a), it is preferable to form the locking piece 41 at a portion that meshes with the slider 7 of the stringer 3 in the lowered state. This stops the slider 7 from escaping upward in the longitudinal direction of the stringer 3.

  Next, the insertion portion 12 of the first bottom stop member 10 is press-fitted into the socket hole 19 of the box portion 17, and the protrusion 30 is press-fitted into the diameter-enlarged socket hole 38 of the box portion 17. At this time, due to the level difference formed on the protrusion 30, the protrusion 39 is flexible when the head 30 a passes, and the protrusion 39 is restored when the bridge-shaped part 30 a next passes, and the protrusion 30. Is connected to the box portion 17 by being fastened in the diameter-expanded socket hole 38, and the user can press-fit while holding the first bottom stop member 10 with the handle 32 using the overhang portion 18 as a guide during this process. In addition, when the first bottom stop member 10 approaches the second bottom stop member 16, the slider storage portion 36 is defined by the holding piece 31 a, the abutting portion 34, and the holding piece 38. Since the play in the short direction of the stringers 2 and 3 can be avoided, the operability is excellent.

When the user pushes the protrusion 30 into the diameter-enlarged socket hole 38 of the box portion 17, the user can confirm the feel of snapping.
