Description

  The present invention relates to a slider for a slide fastener in which a handle can be attached later to a slider body to which a handle holder is fixed, and in particular, a slide that can be easily assembled with a reduced number of components. The present invention relates to a slider for a fastener.

  In order to open and close the opening of clothes, bags, etc., a slide fastener is attached to the opening. In general, a slider used in such a slide fastener includes a slider body having upper and lower blades whose front end sides are connected to each other by a guide post at a predetermined interval, a handle serving as a knob for easily operating the slider, and The slider body is mainly composed of three parts of a handle holding body that holds the handle so that the handle can move and rotate.

  In the conventional slide fastener, for example, a manufacturer of clothing, bags, etc. can arbitrarily select a desired puller from various types of pullers of different colors and forms so that it can easily respond to customer demands and preferences. Many sliders are used so that the handle can be attached later to the slider body to which the handle holder is fixed. In addition, a slider having an automatic stop mechanism that automatically stops sliding of the slider with respect to the fastener element row when, for example, the opening and closing operation of the slide fastener is not performed is also frequently used.

  Furthermore, for example, in Japanese Utility Model Publication No. 4-32974 (Patent Document 1) and Japanese Patent Application Laid-Open No. 2004-187935 (Patent Document 2), a handle can be attached later, and an automatic stop mechanism is provided. A slider for a slide fastener is disclosed. In particular, the slider described in Patent Document 1 is configured not only to be retrofitted with a handle, but also to be able to easily remove and replace the handle once attached to the handle holder. Here, the slider disclosed in Patent Document 1 will be described with reference to FIGS.

  In the slider 100 of Patent Document 1, a mounting piece 116 having a shaft hole 115 is erected on the upper surface of the upper wing plate of the slider body 101, and the stop claw body 103 can swing up and down by using a pin 117 on the mounting piece 116. And one end portion of the downward concave handle holder 102 is externally fitted and fixed in a cantilever manner. In addition, a locking window hole 104 is formed in the upper wing plate of the slider body 101 so as to penetrate the upper wing plate vertically.

  The stop claw 103 has a base end portion 103a, two arm portions 103b extending rearward from the base end portion 103a, and a locking claw portion 103c formed at the tip of the lower arm portion 103b. In addition, an operation groove 107 for accommodating the attachment shaft portion 106a of the handle 106 is formed between the two arm portions 103b.

  In addition, on the lower surface side of the base end portion of the stop claw body 103, a first coil spring 118 is disposed in a small hole formed in the front end portion of the slider body 101. By the first coil spring 118, the locking claw 103c is always urged so as to protrude from the locking window hole 104 of the slider body 101 to the element guide path.

  The handle holder 102 includes a retraction space 111 formed in a concave shape near the rear opening side of the left and right wall portions, a storage space 112 formed in a concave shape near the shoulder opening side, and a space between the retraction space 111 and the storage space 112. And a continuous edge 113 formed continuously. Further, a gap portion 108 through which the attachment shaft portion 106 a of the handle 106 can be inserted is formed between the end portion on the rear opening side of the handle holding body 102 and the upper blade of the slider body 101.

  On the upper wing plate of the slider body 101, an opening / closing member 109 for opening and closing the gap 108 is disposed so as to slide between a gap closing position near the rear opening and a gap opening position near the shoulder opening. Yes. The opening / closing member 109 is always biased toward the gap closed position by the second coil spring 120.

  The opening / closing member 109 is substantially U-shaped when viewed from above, and a bifurcated arm portion includes a first closing portion 110 and a second closing portion 114 projecting upward from the proximal end side. It is formed on the tip side. Thus, the opening / closing member 109 is closed by the first closing portion 110 so that the attachment shaft portion 106a of the handle 106 cannot pass through the gap portion 108 when the opening / closing member 109 is biased and is in the gap closed position. Further, the second closing portion 114 closes the gap between the continuous edge portion 113 of the handle holder 102 and the upper blade of the slider body 101 so that the mounting shaft portion 106a of the handle 106 cannot pass through.

  In the slider 100 of Patent Document 1 having the above-described configuration, firstly, a primary assembly 119 is formed by assembling parts such as the stop claw body 103, the opening / closing member 109, and the handle holder 102 to the slider body 101, and then The assembled primary assembly 119 is assembled by attaching a handle 106.

  In this case, as shown in FIG. 24, the handle 106 is attached by first pushing the attachment shaft portion 106a of the handle 106 into the gap portion 108 to slide the opening / closing member 109 to the front gap opening position. Further, the attachment shaft portion 106 a of the handle 106 is moved into the retreat space 111 of the handle holder 102. At this time, when the attachment shaft portion 106 a of the handle 106 moves into the retreat space 111, the opening / closing member 109 is returned to the original gap closed position shown in FIG. 24 by the bias of the second coil spring 120.

  Next, the attachment shaft portion 106a of the pull handle 106 is moved from the retracting space 111 of the pull handle holding body 102 to a recess formed between the first and second closing portions 110 and 114 of the opening / closing member 109, and the slider body. By pushing toward the front of 101, the opening / closing member 109 is moved to the gap opening position. At this time, the attachment shaft portion 106 a of the handle 106 passes through the lower end of the continuous edge 113 while being accommodated in the recess of the opening / closing member 109, and is accommodated in the operation groove 107 of the stop pawl body 103. .

  After that, when the handle 106 is moved upward and the attachment shaft portion 106a is moved into the storage space 112 of the handle holder 102, there is no interference between the attachment shaft portion 106a and the second closing portion 114 of the opening / closing member 109. The opening / closing member 109 is returned to the gap closed position of FIG. 24 by the bias of the second coil spring 120. As a result, the attachment of the handle 106 is completed, and the handle 106 attached so as to be held by the handle holder 102 is urged to the gap closed position by the second coil spring 120 by the opening / closing member 109, so that the slider Free removal from 100 is prevented.

  On the other hand, when the handle 106 is detached from the slider 100 after the handle 106 is attached, the handle 106 is moved as described above while sliding the opening / closing member 109 between the gap closed position and the gap opening position with a finger or the like. Move in reverse order. As a result, the handle 106 can be easily removed, and thereafter, a new type of handle different from the handle 106 can be attached.

  When the slider 100 with the handle 106 attached is operated as described above, the handle 106 is picked and pulled in an obliquely upward direction or a slider sliding direction by the attachment shaft portion 106a of the handle 106. Since the stop claw body 103 is lifted against the urging force of the first coil spring 118, the locking claw portion 103 c of the stop claw body 103 is retracted from the element guide path of the slider body 101. Thereby, the slider 100 can be freely slid with respect to the fastener chain, and the element row can be easily engaged or detached.

  When the slider 100 is stopped and the handle 106 is released, the stop claw body 103 is urged by the first coil spring 118, and the locking claw portion 103c of the stop claw body 103 is engaged with the locking window hole of the upper blade. 104 protrudes from the element guide path. Thereby, the latching claw 103c is automatically inserted and engaged between the elements of the fastener chain, and the stopped state of the slider can be maintained.

  As shown in FIGS. 25 and 26, the slider described in Patent Document 2 includes a slider body 201, a pull holder body 202 fixed to the slider body 201 in a cantilever manner, and a pull holder body 202. A pin 203 for fixing one end of the slider body 201 to the slider body 201, a stop claw body 204 disposed on the upper wing plate 211 of the slider body 201 so as to swing up and down, and a leaf spring member 205 for biasing the stop claw body 204. A handle (not shown) is attached to the assembly 200 having the above.

  In this case, the upper wing plate 211 of the slider body 201 is formed with a locking window hole 212 that vertically penetrates the upper wing plate 211 and a support groove 213 that supports the stop pawl body 204. The stop claw body 204 is formed at the head that fits into the support groove 213 of the slider body 201, two arm portions that branch out from the head portion, and extend, and at the tip of the lower arm portion. A stop claw 221 is provided, and an operation ditch 222 for accommodating the attachment shaft portion of the handle is formed between the two arm portions.

  The leaf spring member 205 has a stop claw body urging portion 231 bent in a downward convex shape to urge the stop claw body 204, and the stop claw body urging portion 231 is placed on the upper surface of the stop claw body 204. The stop claw body 221 is biased so that the stop claw 221 protrudes from the locking window hole 212 of the slider body 201 into the element guide path. One end portion 223 of the leaf spring member 205 is folded back via a curved portion and is inserted between the upper arm portion 214 of the stop claw member 204 and the upper blade plate 211.

  When attaching a handle to the assembly 200 in such a slider of Patent Document 2, the attachment shaft portion of the handle is formed between the free end side of the handle holder 202 and the upper blade 211 of the slider body 201. And insert along the gap. As a result, the one end portion 223 of the leaf spring member 205 and the upper arm portion 214 of the stop claw body 204 are pushed up by the attachment shaft portion of the pull handle, and the attachment shaft portion enters the operating groove 222 of the stop claw body 204. To do. Further, when the attachment shaft portion enters and the interference between the attachment shaft portion and the one end portion 223 of the leaf spring member 205 is eliminated, the one end portion 223 of the leaf spring member 205 is returned to the original position by the elastic return force. Thus, the gap is closed. This completes the attachment of the handle.

As in the case of the above-mentioned Patent Document 1, when the slider is slid by holding the handle, the slider of Patent Document 2 is stopped by the attachment shaft portion of the handle accommodated in the operation groove 222 of the stop claw body 204. 204 is lifted against the urging force of the leaf spring member 205. Thereby, since the stop pawl 221 retracts from the element guide path, the slider can be freely slid. Further, by releasing the handle after the operation of the slider, the stop claw body 204 is urged by the leaf spring member 205 and the stop claw 221 protrudes from the locking window hole 212 to the element guide path. Can be maintained.
Japanese Utility Model Publication No. 4-32974 JP 2004-187935 A

  In the slide fastener slider, in order to reduce the cost of the slide fastener, for example, it is required to reduce the number of component parts, to facilitate the assembly work of the slider, and to increase productivity. Furthermore, at present, slider assembly is sometimes performed manually, but in many cases, it is mechanically performed using an automatic assembly apparatus having a turntable rotating in the circumferential direction in order to reduce labor costs. For this reason, it is also desired to design the slider configuration so that it can be easily assembled in a mechanical flow operation.

  With respect to these points, in the slider 100 described in Patent Document 1, as shown in an exploded view in FIG. 23, other components are sequentially fitted and fixed to the slider body 101 at predetermined positions. Assembled by. For this reason, in the assembly process of the slider 100 (primary assembly 119), complicated work is rarely required. Therefore, for example, the slider 100 can be easily assembled by hand work, and the slider 100 can be smoothly assembled by mechanical flow work using an automatic assembly apparatus having a turntable. is there.

  However, the slider 100 of Patent Document 1 is configured by using more parts than the slider described in Patent Document 2, for example, and is for biasing the stop pawl body 103 and the opening / closing member 109. As the elastic member, coil springs 118 and 120 which are more expensive than leaf springs are used. For this reason, the slider 100 of Patent Document 1 has a problem that it is difficult to reduce the manufacturing cost, and when the slider is mechanically and automatically assembled, the efficiency of the assembly work cannot be increased due to the large number of parts. .

  On the other hand, the slider of Patent Document 2 has an advantage that the number of components is small and the leaf spring member 205 is used as an elastic member for biasing the stop claw member 204. However, when assembling the slider of Patent Document 2, the stop claw urging portion 231 of the leaf spring member 205 is applied to the upper surface of the stop claw body 204, and the curved one end 223 of the leaf spring member 205 is attached to the stop claw. The stop claw body 204 and the leaf spring member 205 are placed on the slider body 201 in a state of being inserted between the upper arm portion 214 of the body 204 and the upper blade 211, and further the stop claw body 204 and the leaf spring member. An operation of covering and fixing the handle holder 202 on 205 is necessary.

  In other words, the slider of Patent Document 2 omits the arrangement of a member that slides on the slider body such as the sliding member 109 in Patent Document 1 and reduces the number of components of the slider. At the time of assembling, an extremely complicated assembling operation is required in which the leaf spring member 205 is arranged and assembled so as to be wound around from the upper surface side of the stop claw body 204 to the lower surface side of the upper arm portion 214.

  Therefore, in Patent Document 2, although the number of components of the slider is small, for example, when the slider is assembled manually, it is difficult to improve productivity. Further, when the slider assembly operation is mechanically performed using an automatic assembly apparatus or the like, the structure of the apparatus has to be complicated, which has been a major obstacle to cost reduction.

  The present invention has been made in view of the above-described conventional problems, and a specific object thereof is a slider for a slide fastener with an automatic stop mechanism to which a handle can be attached later, and the number of components is reduced.

In this first assembly step, the guide member 43 of the sliding member 4 is fitted into the sliding member accommodating portion 29a of the upper blade 21 and the sliding member 4 is inserted from the rear end side of the upper blade 21 so that the slider body. 2 is slidably fitted.

  Thereafter, the left and right protrusions 29 b arranged on the inlet side (slider rear end side) of the sliding member accommodating portion 29 a are pushed and bent toward the center in the width direction of the slider body 2. At this time, since the concave portion 29d is formed inside the base end portion of the protruding portion 29b, the protruding portion 29b can be easily pushed and bent. In this way, the sliding member 4 is assembled to the upper blade 21 of the slider body 2 so as not to fall off by pushing and bending the protrusion 29b. Furthermore, the stop claw body 6 is fitted into the claw body support part 27 of the slider body 2 from above, and the pivotal support groove 66 of the stop claw body 6 is engaged with the pivotal support part 27 c of the claw body support part 27. Thus, the stop claw body 6 is pivotally supported on the slider body 2 so as to be swingable up and down.

  Further, while performing the first assembling process as described above, a second assembling process for mounting the first leaf spring member 5 in the internal space of the handle holder 3 is performed separately from the first assembling process. In the second assembly step, the holes 51 and 52 formed in the one end portion and the intermediate portion of the first leaf spring member 5 are respectively aligned with the positions of the fixing portion 36a and the engaging portion 36b of the handle holder 3. The first leaf spring member 5 is combined with the handle holder 3, and the fixing portion 36 a and the leg portions 36 c of the engaging portion 36 b are inserted into the hole portions 51 and 52 of the first leaf spring member 5. After that, the leg portions 36c of the fixing portion 36a and the engaging portion 36b are bent so as to open in the left-right direction in a state where the first leaf spring member 5 is combined with the handle holder 3. As a result, the first leaf spring member 5 is mounted in the internal space of the handle holder 3.

  Next, a third assembling step is performed in which the handle body 3 to which the first leaf spring member 5 is attached is fixed to the slider body 2 to which the sliding member 4 and the stop claw body 6 are attached. In this third assembly step, first, the flange 35 of the handle holder 3 is fitted into the fitting groove 28 of the slider body 2 and fixed. Specifically, the first flange 35 a of the pull handle holder 3 is inserted into the second fitting groove 28 b of the slider drum 2 from above with the pull handle holder 3 being shifted forward with respect to the slider drum 2.

  Subsequently, the first and second flanges 35a and 35b of the handle holder 3 are moved to the first and second fitting grooves of the slider body 2 by sliding the handle holder 3 backward along the fitting groove 28. 28a and 28b are respectively fitted into the lateral grooves, and the protrusion 40 of the handle holder 3 is accommodated in the vertical groove of the second fitting groove 28b of the slider body 2 to fit the handle holder 3 to the slider body 2 ( (See FIG. 5).

  After that, by pressing a part of the left and right side wall portions 34a on the fixed end 31 side of the handle holding body 3 toward the first fixing concave portion 14 formed in the claw body supporting portion 27 of the slider body 2, FIG. As shown, a part of the left and right side walls 34 a is fitted into the first fixing recess 14, and the handle holder 3 is crimped and fixed to the nail support 27. Thereby, the attachment strength with respect to the pulling force in the vertical direction of the handle holder 3 can be increased.

  At this time, the raised portion 25 formed on the upper wing plate 21 is pressed toward the second fixing recess 15 formed on the first flange 35 a of the handle holder 3, so that the rear surface side of the upper wing plate 21 is A part is plastically deformed so as to enter the second fixing recess 15. As a result, the attachment strength of the handle holder 3 is further increased to prevent the handle holder 3 from moving in the front-rear direction (the sliding direction of the handle holder 3), so that the handle holder 3 is stabilized to the slider body 2. And can be fixed.

  In the third assembling step as described above, the sliding member 4 and the stop claw body 6 are moved by the first leaf spring member 5 by fixing the handle holding body 3 to which the first leaf spring member 5 is attached to the slider body 2. The primary assembly 10 in the biased state is obtained. At this time, as shown in FIG. 7, the primary assembly 10 has the stop claw body 6 pivotally supported by the claw body support portion 27 of the slider body 2, and the stop claw body of the first leaf spring member 5. Since the biasing portion 53 is biased downward, the claw portion 64 of the stop claw body 6 is projected from the claw hole 30 to the element guide path 24.

  Further, the sliding member 4 slidably fitted to the upper blade 21 of the slider body 2 is urged by the sliding member urging portion 54 of the first leaf spring member 5, so that the handle holder 3 A gap 33 formed between the free end 32 side of the slider body 2 and the upper blade 21 of the slider body 2, and a gap formed between the protruding edge 39 of the handle holder 3 and the upper blade 21. Is held in a cut-off state narrowed by the first blocking portion 41 and the second blocking portion 42 of the sliding member 4 so that the mounting shaft portion 13 of the handle 8 cannot pass. The position of the sliding member 4 at this time is a blocking position that blocks the passage of the attachment shaft 13 of the handle 8.

  In order to attach the handle 8 to such a primary assembly 10, first, the attachment shaft portion 13 of the handle 8 is pushed into the gap 33 from the rear end side of the primary assembly 10. Thus, the sliding member 4 slides forward along the sliding member accommodating portion 29a of the upper blade 21 against the urging force of the sliding member urging portion 54 of the first leaf spring member 5. The gap 33 is moved to a passing position where the gap 33 is open so as to be able to pass through the attachment shaft portion 13 of the handle 8.

  Therefore, the attachment shaft portion 13 of the pull handle 8 passes through the opened gap 33 and is further guided to the rear inclined surface of the first blocking portion 41 of the sliding member 4 to hold the pull handle as shown in FIG. It moves into the retracting portion 37 of the body 3. When the mounting shaft portion 13 of the handle 8 moves to the retracting portion 37, the sliding member 4 pushed forward by the mounting shaft portion 13 is released from the interference with the mounting shaft portion 13. By being biased by the sliding member biasing portion 54 of the spring member 5, the clearance 33 is returned to the blocking position and the gap 33 is blocked.

  After that, as shown in FIG. 9, the attachment shaft portion 13 of the handle 8 accommodated in the retracting portion 37 of the handle holder 3 is moved downward so that the attachment shaft portion 13 is moved to the first and second positions of the sliding member 4. After being accommodated between the second blocking portions 41 and 42, the mounting shaft portion 13 is pushed toward the front side of the slider body 2.

  As a result, the sliding member 4 slides forward again against the urging force of the first leaf spring member 5 along the sliding member accommodating portion 29a of the upper wing plate 21. A gap formed between the edge portion 39 and the upper blade 21 is opened, and the attachment shaft portion 13 of the handle 8 is connected to the handle holding body 3 as shown in FIG. It moves from the retracting part 37 to the accommodating part 38 side. At this time, the attachment shaft portion 13 of the pull handle 8 is guided between the upper and lower arm portions 62 and 63 of the stop claw body 6 and is accommodated in the operation concave groove 65.

  Then, when the attachment shaft portion 13 of the handle 8 moves into the accommodating portion 38 of the handle holder 3, there is no interference between the attachment shaft portion 13 of the handle 8 and the second blocking portion 42 of the sliding member 4. As shown in FIG. 11, the sliding member 4 that has been pushed in is urged by the sliding member urging portion 54 of the first leaf spring member 5 and returns to the blocking position.

  Thereby, attachment of the handle 8 is completed and the slider 1 for slide fasteners of the present Example 1 can be obtained. At this time, the sliding member 4 urged to the blocking position has a gap formed between the protruding edge portion 39 of the handle holding body 3 and the upper blade 21 by the second blocking portion 42. The mounting shaft portion 13 is kept in a blocked state where it cannot pass through. For this reason, it can prevent reliably that the attachment shaft part 13 of the handle 8 is extracted from the inside of the operation ditch | groove 65 of the stop nail | claw body 6. FIG.

  On the other hand, in the slider 1 of the first embodiment, when the handle 8 is removed from the primary assembly 10, first, the attachment shaft portion 13 of the handle 8 is moved into the accommodating portion 38 of the handle holder 3. The sliding member 4 is advanced against the urging force of the first leaf spring member 5. Subsequently, the mounting shaft portion 13 is accommodated between the first and second blocking portions 41 and 42 of the sliding member 4, and the sliding member 4 is further slid toward the blocking position. Thereby, the attachment shaft part 13 of the handle 8 can be moved from the accommodating part 38 to the retracting part 37 side.

  Thereafter, the sliding member urging portion 54 of the first leaf spring member 5 is pressed with, for example, a finger, and the sliding member 4 is moved to the passing position so that the free end 32 side of the handle holder 3 and the upper wing plate 21 are moved. The gap 33 is maintained in an open state. As a result, the handle 8 can be easily removed, and then a different type of handle than the handle 8 can be newly attached.

  As described above, the slider 1 of the first embodiment can attach and replace the handle 8 after assembling the primary assembly, and the stop claw body 6 is urged by the first leaf spring member 5. Then, the claw portion 64 protrudes into the element guide path 24 to provide an automatic stop mechanism that automatically stops the sliding of the slider 1 with respect to the fastener element row inserted through the element guide path 24.

  In addition, the slider 1 includes a first leaf spring member 5 having a single sliding member urging portion 54 that urges the sliding member 4 and a stop claw body urging portion 53 that urges the stop claw body 6. No costly coil spring or the like is used. Thereby, the number of components of the slider 1 can be reduced, and the manufacturing cost can be reduced and the efficiency of the assembly work can be easily achieved.

  In particular, in the slider 1 of the first embodiment, the stop claw body 6 is pivotally supported on the pivot support convex portion 27c of the claw body support portion 27 disposed on the slider body 2 so as to be able to swing up and down. It is configured to be fixedly held in the handle holder 3. For this reason, in the first embodiment, for example, the arrangement of the pin 117 that pivotally supports the stop claw body 103 in the slider 100 of Patent Document 1 can be omitted, and the number of components is further reduced.

  Further, in the slider 1 of the first embodiment, the sliding member 4 is slidably arranged on the upper blade plate 21 and the handle holding body 3 fixedly holding the first leaf spring member 5 is disposed on the upper blade. By being inserted into the plate 21 from the upper surface side and fixed, the first leaf spring member 5 is configured to be assembled in a state where the sliding member 4 and the stop claw body 6 are urged.

  Thereby, in the assembly process of the slider 1, the sliding member 4, the stop claw body 6, and the handle holding body 3 on which the first leaf spring member 5 is fixedly held with respect to the slider body 2 are sequentially placed at predetermined positions. By simply assembling and fixing, the slider 1 can be easily assembled. For example, the complicated and troublesome assembling work for assembling the leaf spring member as in Patent Document 2 is not required. .

  Accordingly, the slider 1 can be easily assembled by, for example, manual work. Further, even when the slider 1 is assembled by a mechanical flow operation using an automatic assembly apparatus or the like having a turntable, the slider can be assembled smoothly and efficiently. For this reason, the productivity of the slider 1 can be significantly improved, and the cost of the slider can be further reduced.

It is set higher than the left and right wall portions 27a and 27b of the claw body support portion 27 formed on the slider body 2. The configuration of the slider body 92 other than the left and right wall portions 27e and 27f is described in the above embodiment. 1 is substantially the same.

  In the pull holder 93, the fixing portion 36a disposed on the inner surface of the pull holder 3 of the first embodiment is excluded, and a third portion is used instead of the engaging portion 36b of the first embodiment. A protruding portion 93a for stabilizing the assembled state of the leaf spring member 95 is provided. The configuration of the handle holder 93 of the third embodiment other than the protrusions 93a is substantially the same as that of the first embodiment.

  The third leaf spring member 95 has first and second contact portions 98 and 99 that come into contact with the inner upper surface portion of the handle holder 93 at one end portion and a curved intermediate portion. Further, the second contact portion 99 of the third leaf spring member 95 is formed with a hole 99a into which the protrusion 93a of the handle holder 93 can be inserted, and the hole 99a and the third leaf spring member 95 are connected to each other. A stop claw urging portion 96 having a bent portion is disposed between the one end portion.
