However, when the clamps with different shapes in the watch are automatically mounted on the slider body, the inside of the clamp supplied by the feeder must be automatically judged, and the clamper in the appropriate direction is transferred to the chute to be supplied to The slider body. In the slider for a slide fastener described in Patent Document 1, the connecting body and the tab are not in a shape to be automatically mounted, and it is necessary to perform the mounting work by hand. Therefore, mass production is difficult. Further, the slide fastener for a slide fastener described in Patent Document 2 does not describe a specific method for automatically determining the inside of the connected body.

In addition, in order to improve the appearance, if a clamp is to be applied before the clamp is attached to the puller, a coating film is formed on the surface of the clamp. Therefore, when the pull tab is attached to the clamp after painting, the film laminated on the portion of the pull tab causes a change in the angular shape of the portion, thereby reducing the bonding strength between the clamp and the pull tab. Therefore, there is a possibility that the pull-tab is detached.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a slider that can be designed to meet customer needs by a clamp to improve design, and to automatically mount a slider body and a clamper. Mass produced sliders for zippers.

According to the sliding member for a slide fastener of the present invention, since the other end portion of the clamper has a mounting portion formed by attaching a pull tab, the pull tab of the design that satisfies the customer's needs can be mounted on the clamper. Improve design. Furthermore, since the clamper is provided with a protrusion between the ring portion and the mounting portion, when the slider body and the clamp are automatically mounted, the inside of the clamp can be automatically judged by the feeder according to the direction of the protrusion. Therefore, only the clamper in a suitable direction can be supplied to the slider main body, and the slider main body and the clamper can be automatically mounted, so that the slide fastener for mass production can be mass-produced at low cost. Further, since the protruding portion is provided between the ring portion and the mounting portion, the protruding portion does not affect the turning operation of the clamp or the mounting of the pull tab.

Further, according to the slide fastener for a slide fastener of the present invention, when the pull tab is attached to the clamp, the projection of the clamp is housed in the projection receiving portion of the pull tab, so that the projection is not conspicuous and can be obtained as 2 The integration of the clamps and the pull tabs of different parts can further improve the design of the slider for the zipper.

Further, according to the slide fastener for a slide fastener of the present invention, since the projection portion is disposed at a position deviated from the position of the center of gravity of the clamper toward the longitudinal direction of the clamper, the clamp is automatically carried by the feeder when the clamp is automatically conveyed. Since the center of gravity is rotated downward with the projection for locking, the center of gravity is turned downward, so that it can be automatically aligned in an appropriate direction, and the operating rate of the automatic mounting machine can be improved.

Further, according to the sliding member for a slide fastener of the present invention, the attachment portion of the clamp includes an insertion portion, and a fastening piece having the extending portion and the locking projection, and is provided at a boundary portion between the extending portion and the fastening projection. Concave. Thereby, even if the clamp is applied, the coating applied to the boundary portion between the extending portion and the fastening projection is accumulated as a coating film in the concave portion, so that the abutment of the locking projection and the locking hole of the pull tab can be maintained. The angular shape of the face maintains the strength of the bond between the clamp and the pull tab, thereby positively securing the pull tab to the clamp.

Further, according to the sliding member for a slide fastener of the present invention, the surface of the insertion portion opposite to the fastening projection is formed such that the thickness of the insertion portion thereof gradually increases from the base portion of the insertion portion toward the opposite direction of the ring portion. Therefore, when the bending force is generated toward the protrusion side from the vicinity of the step of the clamper, the contact surface of the insertion portion and the pull tab can be ensured, and the friction is utilized. The resistance prevents slippage and prevents the tab from falling out of the clamp.

Hereinafter, an embodiment of the slide fastener for a slide fastener of the present invention will be described in detail based on the drawings.

The left and right side wall portions 16 are erected along the left and right side edges of the two wings 14 and 15; the guide post 17 is attached to the left and right central portions of the introduction port side and connects the two wings 14 And a pair of front and rear mounting post portions 18a, 18b constituting the tab mounting post 18 and disposed on the upper side of the upper flap 14. The slider main body 11 is formed of a resin material, and a substantially Y-shaped space is observed by a plane defined by the two flaps 14 and 15, the pair of left and right side wall portions 16, and the guide post 17, and is a chain not shown. The guiding path 19 of the tooth. Further, the slider main body 11 of the present embodiment constitutes the pull tab mounting post 18 together with the lid portion 18c that is fastened to the pair of front and rear mounting post portions 18a and 18b.

Further, the clamper 20 is formed of, for example, a resin material, and the ring portion 21 formed on one end side in the longitudinal direction and the attachment portion 22 of the attachment tab 40 formed on the other end side are coupled to the central portion 24. One piece is formed.

In the following description, the opening that separates the fastener elements on the side where the width of the upper blade 14 (the lower blade 15) is larger is referred to as the introduction port, and the fastener on the opposite side (the side with the smaller width) is attached. The meshing opening is referred to as a meshing opening. The direction in which the inlet and the engagement port are connected (the sliding direction of the slider body 11) is the front-rear direction (the longitudinal direction of the clamper 20 in FIGS. 6(a) and (b)), and is orthogonal to the front-rear direction. The direction is the left-right direction (the width direction of the clamper 20), and the direction orthogonal to the front-back direction and the left-right direction is the front-back direction (the plate thickness direction of the clamper 20).

Between the pair of mounting post portions 18a, 18b before and after the tab mounting post 18, the shaft portion 23 of the ring portion 21 formed at one end of the clamper 20 is inserted, and the latch pin is inserted across the shaft portion 23. The 12 is disposed on the slider main body 11, and the cover portion 18c is attached to the mounting post portions 18a and 18b so as to cover the shaft portion 23 of the ring portion 21 and the lock pin 12 as a whole. Thereby, the clamper 20 is rotatably attached to the slider body 11 around the shaft portion 23. Further, the lock pin 12 has a claw portion 12a which is freely detachable from the guide passage 19 of the fastener element from the through hole 14b provided in the upper blade 14. When the pull tab 40 is pulled, the claw portion 12a is disengaged from the guide passage 19. While the slide member 10 is allowed to move, when the pull tab 40 is lowered, the claw portion 12a protrudes into the guide passage 19 through the through hole 14b, and protrudes between the two fastener elements existing in the guide passage 19 to prevent the slider from moving. Further, the lock pin 12 and the lid portion 18c are made of, for example, a thin plate spring steel or a resin material.

As shown in FIGS. 2(a) to 4(b), the ring portion 21 of the clamper 20 is connected to the front end of the pair of left and right wrist portions 27 extending from the central portion 24 by the shaft portion 23, and is formed in the center. A substantially rectangular frame shape of the hole portion 26 is provided. The cross-sectional shape of the shaft portion 23 is substantially circular, and is rotatable in the space portion 18d of the tab mounting post 18 divided by the mounting post portions 18a, 18b and the lid portion 18c.

Further, the attachment portion 22 of the clamper 20 includes a door-shaped plate-shaped insertion portion 28 that protrudes from the center portion 24 in a direction opposite to the ring portion 21, and a locking piece 29 that is formed inside the insertion portion 28. The locking piece 29 includes an extending portion 30 extending from the base portion 36 of the insertion portion 28 in a direction opposite to the ring portion 21, and a locking protrusion 31 formed by bending from the front end portion of the extending portion 30 in the thickness direction. The latching projection 31 has a height protruding from the surface of the insertion portion 28 so as to be fastened to the locking hole 45 of the tab 40 to be described later when the pull tab 40 is attached.

Further, at the boundary portion between the extending portion 30 and the locking projection 31, a concave portion 32 which is coated in the boundary portion is provided in the width direction of the clamper 20 (see Fig. 4(b)). Further, when the pull tab 40 is attached to the clamper 20, since the latching projection 31 pushes the latching hole 45 against the ring portion 21 side of the clamper 20, the recessed portion 32 is substantially not affected by the rigidity. The depth of the degree is formed at a position in the vicinity of the extending portion 30 which does not affect the boundary portion of the above-mentioned pushing.

Further, the surface 35 of the insertion portion 28 in the direction in which the locking projection 31 protrudes is formed substantially straight in the longitudinal direction, but the surface 33 of the insertion portion 28 on the side opposite to the protruding direction of the locking projection 31 is inserted. The base portion 36 of the portion 28 gradually increases the thickness t of the insertion portion 28 toward the distal end side, and becomes an inclined surface that is inclined outward in the thickness direction.

Moreover, the thickness of the mounting portion 22 is thinner than the thickness of the ring portion 21. Further, the width of the mounting portion 22 is smaller than the width of the ring portion 21, and therefore, at the central portion 24 of the clamper 20, the ring portion 21 and the mounting portion 22 The boundary portion is formed over the entire circumference to form the step portion 34. Further, in the central portion 24 between the ring portion 21 and the mounting portion 22, a projection portion 25 is formed in the intermediate portion in the width direction of one side surface in the thickness direction of the clamper 20. Specifically, the protruding portion 25 is formed at a side surface of the clamper 20 in a direction in which the locking projection 31 protrudes, a position adjacent to the step portion 34 on the side of the mounting portion 22, and is provided to protrude more than the surface of the ring portion 21. In the direction of the plate thickness. Further, since the protruding portion 25 is formed on the side of the mounting portion 20 of the center portion 24, it is disposed offset from the center of gravity G of the clamper 20 set on the side of the ring portion 21 in the longitudinal direction of the clamper 20. Position (refer to Fig. 6 (a), (b)).

Here, the center of gravity G is generally the center position in the longitudinal direction and the width direction of the clamper 20, but is slightly different from the center position by the difference in weight generated by the shape of the ring portion 21 and the mounting portion 22. The length direction of the clamp is deviated. In the present embodiment, the center of gravity position G is biased closer to the ring portion 21 than the center position.

The pull tab 40 is a substantially lance-shaped plate-like member which is formed by integrally forming a joint portion 42 having a substantially rectangular thick plate shape from the side surface of the annular grip portion 41. A clamp accommodating portion 43 as a square hole that is opened at the end surface 44 is formed in the connecting portion 42. The clamper accommodating portion 43 has a size substantially equal to that of the insertion portion 28, so that the step portion 34 of the clamper 20 abuts against the end surface 44 of the pull-tab 40, and the insertion portion 28 of the mounting portion 22 can be stably inserted.

Further, when the attachment portion 22 is inserted into the clamper accommodating portion 43 in the tab 40, the locking hole 45 is formed at a position corresponding to the locking projection 31, and the end surface corresponding to the projection portion 25 is formed from the end surface. 44 is formed with a rough The notch-shaped projection accommodating portion 46. Thereby, the attachment portion 22 is inserted into the clamper accommodating portion 43 while the extension portion 30 of the buckle piece 29 is elastically deformed, and when the buckle projection 31 is fastened to the buckle hole 45, the projection portion 25 is housed in the projection portion 25 The protrusion accommodating portion 46. In this state, the surface of the tab 40 around the projection accommodating portion 46 is set to have a height substantially equal to the height of the projection portion 25 of the clamper 20.

Next, the mounting of the slide fastener 10 will be described. Here, the mounting of the slider main body 11 and the clamper 20, in particular, the order in which the clamper 20 is supplied to the slider main body 11 in the direction in which the clamper 20 is suitable will be described. The zipper slider 10 automatically mounts the slider body 11, the clamper 20, the lock pin 12, and the lid portion 18c by an automatic mounting machine, and then manually mounts the tab 40 that satisfies the customer's needs. Further, although the clamper 20 and the pull tab 40 are colored by painting as needed, the clamper 20 is pre-coated before mounting.

Each of the feeders of the automatic mounting machine (for example, a vibrating feeder) sequentially supplies the slider body 11, the clamper 20, the lock pin 12, and the lid portion 18c in a direction suitable for each particular direction. First, the slider body 11 supplied to the specific direction by the feeder is held in the automatic mounting machine. Thereafter, the ring portion 21 of the clamper 20 is automatically mounted between the mounting column portions 18a, 18b of the slider body 11.

The clamper 20 automatically determines the direction of the longitudinal direction and the inside of the front surface by the feeder, and supplies the direction and the surface to the slider body 11 in a suitable direction. As shown in Fig. 7 (a) and (b), in the surface determination unit 55 provided in the conveyance path, a pair of gaps C having substantially the same width as the thickness of the ring portion 21 are slightly inclined. Sheets 56A, 56B. One of the plates 56A is formed with a width and a depth greater than the size of the protrusions 25. Word gap 57.

When the clamper 20 that is conveyed while the vibration is conveyed by the conveyance path reaches the front and back determination unit 55, it falls into the gap C between the pair of sheets 56A and 56B. At this time, since the center of gravity G is located on the side of the ring portion 21, the clamper 20 rotates with the protrusion 25 for locking as the central axis, and the ring portion 21 faces downward, causing the ring portion 21 to fall into a pair of plates. Clearance C between 56A and 56B.

Since the clamper 20 is engaged with the plate members 56A and 56B of either of the front and rear determination portions 55, the clamper 20 does not fall from the gap C, and the ring portion 21 is made to be vibrated by the vibration imparted to the clamper 20. The state toward the lower side is conveyed between the pair of inclined plates 56A, 56B.

Thereafter, as shown in Fig. 7 (a) and Fig. 8 (a), at the position where the notch 57 of the plate member 56A is formed, the projection portion 25 of the projection portion 25 toward the plate member 56A has its projection portion 25 passed through the notch 57. fall. Thereby, the clamper 20 in the direction in which the inside of the watch faces the wrong direction is excluded from the conveyance path.

On the other hand, as shown in Fig. 7 (b) and Fig. 8 (b), the clamper 20, which is conveyed in the direction in which the direction of the front surface is conveyed in the appropriate direction, is protruded from the plate member 56B, and is not It is further transported while being dropped by the notch 57. Thereby, the clamper 20 suitable for the longitudinal direction and the direction of the front surface is supplied to the slider main body 11 via the chute (not shown), and the shaft part 23 is attached to the handle mounting post 18.

Thereafter, the lock pin 12 and the lid portion 18c are sequentially supplied to the slider body 11, and the clamper 20, the lock pin 12, and the lid portion 18c are attached to the slider body 11.

Further, the clamper 20 for attaching the upper slider body 11 is manually inserted into the mounting portion 22 by the clamp receiver portion 43 of the pull tab 40 until the latching projection 31 is fastened to the latching hole 45. The pull tab 40 is attached to the mounting portion 22. Further, in this state, the protruding portion 25 is housed in the projection accommodating portion 46.

As described above, in the state in which the pull tab 40 is attached to the clamper 20, since the face 33 of the insertion portion 28 on the side opposite to the protruding direction of the buckle projection 31 is an inclined surface, when the clamp 20 is generated When the vicinity of the step portion 34 is a bending force toward the protruding portion side, the contact surface between the insertion portion 28 and the tab 40 can be more ensured than in the case of the non-inclined surface, and the friction can be prevented by the frictional resistance, thereby preventing the tab from being pulled. 40 off.

Further, since the concave portion 32 is provided at the boundary portion between the extending portion 30 and the engaging projection portion 31, the coating material applied to the boundary portion is accumulated as a coating film in the concave portion 32, thereby securing the locking hole 45 and the buckle of the pull tab 40. The angular shape of the abutting surface of the stopper portion 31 maintains the bonding strength between the clamper 20 and the tab 40, so that the tab 40 can be prevented from accidentally coming off the clamper 20.

Moreover, since the slider main body 11, the clamper 20, and the pull tab 40 are formed of a resin material, the slide fastener 10 can be manufactured lightly and at low cost. Furthermore, since the pull tab 40 can be subsequently mounted and replaced with 811/038/3, the color, shape, and the like of the customer can be easily and easily matched. For example, the slide fastener 10 having a large change in the two color tones of the slider main body 11 and the pull tab 40 can be easily obtained.

As described above, according to the slide fastener 10 of the present embodiment, since the other end portion of the clamper 20 has the attachment portion 22 which is formed by attaching the tab 40, the handle can be designed to satisfy the customer's needs. 40 is mounted to the clamp 20 to improve design. Moreover, since the protrusions 25 are provided between the ring portion 21 and the mounting portion 22 on the clamper 20, when the slider body 11 and the clamper 20 are automatically mounted, the feeder can be automatically used according to the direction of the protrusions 25. The inside of the table of the clamper 20 is judged. Therefore, only the clamper 20 of a suitable direction can be supplied to the slider main body 11, and the slider main body 11 and the clamper 20 can be automatically mounted, and the slide fastener 10 can be mass-produced at low cost. Further, since the protruding portion is provided between the ring portion and the mounting portion, the rotation of the clamp or the attachment of the pull tab is not affected by the protruding portion.

Further, when the pull tab 40 is attached to the clamper 20, since the projection portion 25 of the clamper 20 is housed in the projection accommodating portion 46 of the pull tab 40, the projection portion 25 is not conspicuous, and two different parts can be obtained. The clamper 20 and the pull tab 40 obtain a sense of unity, and the design of the slide fastener 10 can be further improved.

Further, since the protruding portion 25 is provided between the ring portion 21 of the clamper 20 and the mounting portion 22 and is offset from the center of gravity G of the clamper 20 in the longitudinal direction of the clamper 20, the feed portion is fed. When the clamp 20 is automatically conveyed, the clamper 20 rotates with the projection 25 for locking as the central axis and the center of gravity G side faces downward, so that the appropriate direction can be automatically adjusted, thereby improving the automatic installation. The operating rate of the machine.

Further, the attachment portion 22 of the clamper 20 includes an insertion portion 28 that is inserted into the clamper housing portion 43 formed in the pull tab 40, and a locking piece 29 that has a loop from the base portion 36 of the insertion portion 28. The extending portion 30 extending in the opposite direction of the portion 21 and the locking projection 31 formed at the front end portion of the extending portion 30. A recess 32 is provided at a boundary portion between the extending portion 30 and the latching projection 31. Thereby, when the clamp 20 is applied, the coating applied to the boundary portion between the extending portion 30 and the fastening projection 31 is accumulated as a coating film in the concave portion 32, so that the locking projection 31 and the pull tab 40 can be held. The angular shape of the abutting surface of the latching hole 45 maintains the bonding strength between the clamper 20 and the tab 40, thereby positively holding the tab 40 to the clamper 20.

Further, according to the slide fastener 10 of the present invention, the surface 33 of the insertion portion 28 on the opposite side of the buckle projection 31 is such that the thickness t of the insertion portion 28 is from the base portion 36 toward the opposite direction of the ring portion 21. The inclined surface is gradually increased, and therefore, when a bending force toward the projection side is started from the vicinity of the step portion 34 of the clamper 20, the insertion portion 28 and the pull tab can be ensured as compared with the case without the inclined surface. The contact surface of 40 is prevented from slipping by the frictional resistance, thereby preventing the tab 40 from coming off the clamper 20.

Further, the present invention is not limited to the above embodiment, and suitable modifications, improvements, and the like can be implemented.

For example, in the above description, the clamper 20 is applied as needed, but it may be formed by adjusting the color of the resin material to a desired color before forming.

Moreover, the above description of the projection accommodating portion 46 is approximate The notch of the glyph may be formed by recessing the inner surface of the clamp accommodating portion 43 so as to have a thin portion covering the upper surface of the projection portion 25, and the projection portion 25 may be made out of the tab 40. To. Thereby, since the protruding portion 25 is hidden inside the tab 40, the appearance is beautiful, thereby further improving the design.

Further, the slider main body 11 having the tab attachment portion 18 may have at least a pair of front and rear mounting post portions 18a and 18b as described in the embodiment, and the lid portion 18c is fastened to the mounting post portions 18a and 18b. Further, the tab mounting post 18 may have a tab mounting post 18, and one end portion thereof is mounted with a clamp by reinforcing the other end portion while extending from the upper flap 14 and accommodating the shaft portion 23 of the ring portion 21. 20.
