  By the way, when automatically assembling clampers with different front and back shapes into the slider body, the front and back surfaces of the clamper supplied from the parts feeder are automatically identified, and the clamper with the proper orientation is transferred to the chute to slide the slider. It is necessary to supply the fuselage. In the slider for a slide fastener described in Patent Document 1, the connecting body and the puller are not shaped in consideration of automatic assembly, and require manual assembly work, so that mass production is difficult. Further, the slide fastener slider described in Patent Document 2 also does not describe a specific method for automatically discriminating the front and back surfaces of the connected body.

  In addition, in order to improve the appearance, when the clamper is applied before the handle is assembled to the clamper, a paint film is formed on the surface of the clamper. For this reason, when the handle is assembled to the clamper after painting, the angle shape of the part is changed by the film laminated on the part where the handle is locked, so that the coupling strength between the clamper and the puller is lowered and the handle is detached. There was a possibility.

  The present invention has been made in view of the above-mentioned problems, and its purpose is to improve the design by attaching a handle according to the customer's request to the clamper and to automatically assemble the slider body and the clamper. An object of the present invention is to provide a slide fastener slider that can be used for mass production.

The above object of the present invention can be achieved by the following constitution.
(1) a slider body having a handle attachment post;
A slide fastener slider comprising: a link part attached to the puller attachment column of the slider body at one end part; and a clamper having an attachment part configured to attach a handle to the other end part;
The slide fastener slider is characterized in that the clamper is provided with a protrusion protruding in the plate thickness direction of the clamper between the link portion and the attachment portion.
(2) The slider for a slide fastener according to (1), wherein the pulling handle is provided with a protrusion accommodating portion for accommodating the protruding portion.
(3) The protrusion may be provided between the link portion of the clamper and the mounting portion, and at a position that deviates from the center of gravity of the clamper in the longitudinal direction of the clamper. The slider for the slide fastener described.
(4) The attachment portion of the clamper is locked to a plate-like insertion portion configured to be inserted into a clamper housing portion formed on the handle and a locking hole formed on the handle. A locking piece configured to be
The locking piece enters the locking hole when the extension portion extending in a direction opposite to the link portion from the base portion of the insertion portion and the attachment portion is inserted into the clamper accommodating portion. And a locking projection formed by bending from the tip of the extending portion,
The slide fastener slider according to any one of (1) to (3), wherein a concave portion is provided at a boundary portion between the extension portion and the locking projection.
(5) The surface of the insertion portion opposite to the side from which the locking projection protrudes gradually increases the thickness of the insertion portion from the base portion of the insertion portion toward the opposite direction to the link portion. (4) The slide fastener slider according to (4), characterized in that it has an inclined surface.

  According to the slide fastener slider of the present invention, the other end portion of the clamper has an attachment portion configured to be attached with a handle, so that the design can be improved by attaching the handle according to the customer's request to the clamper. Can be improved. In addition, the clamper is provided with a protrusion between the link part and the mounting part, so when the slider body and clamper are automatically assembled, the front and back surfaces of the clamper are automatically identified by the parts feeder according to the direction of the protrusion. It becomes possible to do. Therefore, it is possible to supply only the clamper in the proper direction to the slider body and automatically assemble the slider body and the clamper, and to mass-produce the slide fastener slider at low cost. In addition, since a projection part is provided between a link part and an attachment part, a projection part does not affect the rotation operation of a clamper, or attachment of a handle.

  Further, according to the slide fastener slider of the present invention, when the handle is assembled to the clamper, the protrusion of the clamper is accommodated in the protrusion accommodating portion of the handle, so that the protrusion does not stand out and two different parts are used. A sense of unity between a certain clamper and a handle can be obtained, and the design of the slider for the slide fastener can be further improved.

  Further, according to the slide fastener slider of the present invention, since the protrusion is provided at a position deviated from the center of gravity of the clamper in the longitudinal direction of the clamper, the clamper is caught when the clamper is automatically conveyed by the parts feeder. Since the center of rotation of the projection is the center axis, the center of gravity is rotated downward, so that it can be automatically adjusted to an appropriate direction, and the operating rate of the automatic assembly machine can be improved.

  Further, according to the slide fastener slider of the present invention, the clamper mounting portion includes the insertion portion and the locking piece having the extending portion and the locking projection, and the extending portion and the locking projection. A concave portion is provided at the boundary portion. As a result, even if the clamper is painted, the paint applied to the boundary between the extended portion and the locking projection remains in the recess as a coating film. The angle shape of the surface is maintained, the coupling strength between the clamper and the handle is maintained, and the handle is securely locked to the clamper.

  Further, according to the slide fastener slider of the present invention, the surface of the insertion portion on the side opposite to the locking protrusion gradually increases the thickness of the insertion portion from the base portion of the insertion portion toward the direction opposite to the link portion. Since it has an increasing inclined surface, when a bending force is generated toward the protruding part starting from the vicinity of the step of the clamper, the contact surface between the insertion part and the handle is ensured more than when there is no inclined surface, and the friction is increased. The resistance prevents slipping and prevents the handle from coming off the clamper.

  Hereinafter, embodiments of a slider for slide fastener according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is an exploded perspective view of a slide fastener slider according to the present invention. The slide fastener slider 10 includes a slider body 11, a lock pin 12 that is an elastic member, a cover 18c that constitutes a pulling attachment column 18, and A clamper 20 and a handle 40 are provided.

  4 (a), 4 (b) and 6 (a), 6 (b), the slider body 11 is an upper wing plate having substantially the same shape and arranged in parallel and spaced apart in the plate thickness direction. 14 and the lower wing plate 15, a pair of left and right side wall portions 16 erected along the left and right side edges of the wing plates 14, 15, and the wing plates 14, 15 connected to the shoulder opening side left and right central portions. A guide column 17 and a pair of front and rear mounting column portions 18 a and 18 b provided on the upper surface of the upper blade 14 constituting the pulling column mounting column 18 are provided. The slider body 11 is formed of a resin material, and a substantially Y-shaped space in plan view defined by the two blades 14 and 15, the pair of left and right side wall portions 16 and the guide pillars 17 is a fastener element (not shown). The guide passage 19 becomes. Further, the slider body 11 of the present embodiment constitutes the pull handle attachment column 18 together with the cover 18c that is locked to the pair of front and rear attachment column portions 18a and 18b.

  Further, the clamper 20 is formed of, for example, a resin material, and a link portion 21 formed on one end side in the longitudinal direction and an attachment portion 22 to which a handle 40 formed on the other end side is attached are formed in the central portion 24. And are integrally molded.

  In the following description, the opening from which the upper wing plate 14 (lower wing plate 15) is wide and from which the fastener element is separated is referred to as a shoulder opening, and on the opposite side (narrow side). The opening through which the fastener element meshes is called the rear opening. The direction connecting the shoulder opening and the rear opening (sliding direction of the slider body 11) is the front-rear direction (longitudinal direction of the clamper 20 in FIGS. 6A and 6B), and the direction orthogonal to the front-rear direction is the left-right direction (clamper 20 width direction), the front-rear direction, and the direction orthogonal to the left-right direction are front and back directions (plate thickness direction of the clamper 20).

  A shaft portion 23 of the link portion 21 formed at one end portion of the clamper 20 is inserted between the pair of front and rear mounting column portions 18 a and 18 b of the pulling handle mounting column 18, and the lock pin 12 extends across the shaft portion 23. A cover 18c is disposed on the slider body 11 and is attached to the mounting pillars 18a and 18b so as to cover the shaft part 23 of the link part 21 and the entire lock pin 12. Thus, the clamper 20 is attached to the slider body 11 so as to be rotatable about the shaft portion 23. Further, the lock pin 12 includes a claw portion 12a that can freely move in and out of the guide passage 19 of the fastener element from a through hole 14b provided in the upper wing plate 14, and when the handle 40 is pulled, the claw portion 12a is guided to the guide passage 19. When the slider 40 is allowed to move and the handle 40 is tilted, the claw portion 12a enters the guide passage 19 through the through hole 14b and enters between the two elements existing in the guide passage 19 To prevent the slider from moving. Note that the lock pin 12 and the cover 18c are made of, for example, thin plate spring steel and a resin material.

  As shown in FIG. 2A to FIG. 4B, the link portion 21 of the clamper 20 has a pair of left and right arm portions 27 extending from the central portion 24 connected to each other by a shaft portion 23. It is formed in a substantially rectangular frame shape with a hole 26 in the center. The cross-sectional shape of the shaft portion 23 is substantially circular, and is rotatable within the space portion 18d of the pull handle mounting column 18 defined by the mounting column portions 18a and 18b and the cover 18c.

  Further, the mounting portion 22 of the clamper 20 includes a gate-shaped plate-like insertion portion 28 that is formed to project from the central portion 24 in the direction opposite to the link portion 21, and a locking piece 29 that is formed inside the insertion portion 28. And comprising. The locking piece 29 is formed by extending from the base portion 36 of the insertion portion 28 in the direction opposite to the link portion 21 and by bending from the distal end portion of the extension portion 30 in the plate thickness direction. And the locking projection 31. The locking projection 31 has a height that protrudes from the surface of the insertion portion 28 so as to be locked in a locking hole 45 of the pulling handle 40 described later when the pulling handle 40 is attached.

  Moreover, the recessed part 32 which receives the coating collected in this boundary part is provided in the boundary part of the extension part 30 and the latching protrusion 31 along the width direction of the clamper 20 (refer FIG.4 (b)). When the handle 40 is attached to the clamper 20, the locking projection 31 presses the locking hole 45 against the link portion 21 side of the clamper 20, so that the recess 32 extends the boundary portion that does not affect the pressing. It is formed at a position close to the portion 30 and at a depth that does not substantially affect the rigidity.

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

In addition, since the thickness of the attachment portion 22 is smaller than the thickness of the link portion 21 and the width of the attachment portion 22 is smaller than the width of the link portion 21, the link portion 21 and the attachment portion are arranged in the central portion 24 of the clamper 20. A stepped portion 34 is formed on the entire boundary of the boundary portion 22. Further, a protrusion 25 is formed at the center portion 24 between the link portion 21 and the attachment portion 22 at the intermediate portion in the width direction of one side surface of the clamper 20 in the plate thickness direction. Specifically, the protruding portion 25 is formed on the side surface of the clamper 20 in the direction in which the locking protruding portion 31 protrudes, at a position adjacent to the step 34 on the mounting portion 22 side, and further than the surface of the link portion 21. It is provided so as to protrude in the thickness direction. Further, since the protruding portion 25 is formed on the mounting portion 20 side of the central portion 24, the protruding portion 25 is provided at a position deviating from the center of gravity position G of the clamper 20 set on the link portion 21 side in the longitudinal direction of the clamper 20 (FIG. 6 (a) and (b)).
Here, the center-of-gravity position G is normally the center position in the longitudinal direction and the width direction of the clamper 20, but due to the difference in weight based on the difference in shape between the link part 21 and the attachment part 22, it is slightly more than the center position. It is slightly displaced in the longitudinal direction of the clamper. In the present embodiment, the gravity center position G is shifted closer to the link portion 21 than the center position.

  The puller 40 is a plate-like member having a generally rectangular shape in plan view, which is integrally formed by extending a substantially rectangular thick plate-like connecting portion 42 from the side surface of the ring-shaped knob 41. The coupling portion 42 is formed with a clamper accommodating portion 43 that is a bag hole opened in the end surface 44. The clamper accommodating portion 43 has substantially the same dimensions as the insertion portion 28 so that the insertion portion 28 of the attachment portion 22 is inserted without rattling until the step portion 34 of the clamper 20 contacts the end surface 44 of the handle 40. Have.

  In addition, when the attachment portion 22 is inserted into the clamper accommodating portion 43, the catch 40 has a locking hole 45 at a position corresponding to the locking projection 31 and an end surface at a position corresponding to the projection 25. A protrusion accommodating portion 46 is formed by cutting out from 44 to a substantially U-shape. As a result, when the mounting portion 22 is inserted into the clamper accommodating portion 43 while the extended portion 30 of the locking piece 29 is elastically deformed, and the locking projection 31 is locked in the locking hole 45, the protruding portion 25 is projected. It is accommodated in the accommodating part 46. In this state, the surface of the handle 40 around the protrusion accommodating portion 46 is set to a height substantially equal to the height of the protrusion 25 of the clamper 25.

  Next, assembly of the slide fastener slider 10 will be described. Here, the description will focus on the assembly of the slider body 11 and the clamper 20, particularly the procedure for supplying the slider body 11 to the slider body 11 with the clamper 20 in an appropriate orientation. In the slide fastener slider 10, the slider body 11, the clamper 20, the lock pin 12, and the cover 18c are sequentially and automatically assembled by an automatic assembling machine, and then the handle 40 according to customer requirements is assembled manually. The clamper 20 and the handle 40 are colored by painting as necessary, but the clamper 20 is painted in advance before assembly.

  Each parts feeder (for example, a vibratory parts feeder) of the automatic assembly machine sequentially supplies the slider body 11, the clamper 20, the lock pin 12, and the cover 18c while directing them in a predetermined appropriate direction. First, the slider body 11 supplied in a predetermined direction by the parts feeder is held by the automatic assembly machine. Then, the link portion 21 of the clamper 20 is automatically assembled between the mounting column portions 18 a and 18 b of the slider body 11.

  The clamper 20 is automatically identified by the parts feeder in the longitudinal direction and the front and back surfaces, and the direction and the surface are directed in an appropriate direction and supplied to the slider body 11. As shown in FIGS. 7A and 7B, in the front / back discriminating portion 55 provided in the transport path, the pair of plate members 56A and 56B have gaps C having substantially the same width as the thickness of the link portion 21, respectively. Oppositely arranged in a slightly inclined state. One plate member 56 </ b> A is formed with a U-shaped notch 57 having a width and depth larger than the dimensions of the protrusion 25.

  When the clamper 20 conveyed while being vibrated from the conveyance path reaches the front / back discriminating portion 55, it falls into the gap C between the pair of plate members 56A, 56B. At this time, since the gravity center position G is located on the link part 21 side, the clamper 20 rotates with the projection part 25 for catching as a central axis and the link part 21 side is turned downward, and the link part 21 is a pair of plate members 56A, It falls into the gap C of 56B.

  The clamper 20 does not fall from the gap C because the protrusion 25 is hooked on any one of the plate members 56A and 56B of the front / back discriminating unit 55, and the pair of inclined plate members 56A by vibration applied to the clamper 20 , 56B with the link portion 21 facing downward.

  Then, as shown in FIGS. 7A and 8A, at the position where the notch 57 of the plate material 56A is formed, the protrusion 25 of the clamper 20 in which the protruding portion 25 faces the plate material 56A side is notched 57. Fall through. Thereby, the clamper 20 whose front and back faces in the wrong direction is excluded from the conveyance path.

  On the other hand, as shown in FIGS. 7 (b) and 8 (b), the clamper 20 conveyed with the front and back sides facing the proper direction falls with the protrusions 25 locked to the plate material 56B. Without passing through the notch 57, it is further conveyed. As a result, the clamper 20 with the proper longitudinal direction and front and back direction is supplied to the slider body 11 via the chute (not shown), and the shaft portion 23 is attached to the pulling attachment column 18.

  Subsequently, the lock pin 12 and the cover 18 c are sequentially supplied to the slider body 11, and the clamper 20, the lock pin 12, and the cover 18 c are attached to the slider body 11.

  The clamper 20 attached to the slider body 11 is manually inserted into the attachment portion 22 by inserting the clamper housing portion 43 of the handle 40 into the attachment portion 22 until the locking projection 31 is locked in the locking hole 45. 40 is attached to the attachment portion 22. In this state, the protrusion 25 is accommodated in the protrusion accommodating portion 46.

  Thus, in the state where the handle 40 is attached to the clamper 20, the surface 33 of the insertion portion 28 on the opposite side to the protruding direction of the locking projection 31 is an inclined surface. When a bending force is generated toward the protruding portion starting from the vicinity, the contact surface between the insertion portion 28 and the handle 40 is secured more than when there is no inclined surface, slippage is prevented by frictional resistance, and the pull-out of the handle 40 is prevented. Is prevented.

  Further, since a recess 32 is provided at the boundary portion between the extension portion 30 and the locking projection 31, the paint applied to the boundary portion accumulates in the recess 32 as a coating film, and the locking hole 45 of the handle 40. The angle shape of the contact surface between the engaging protrusion 31 and the locking protrusion 31 is maintained, and the coupling strength between the clamper 20 and the handle 40 is maintained, so that the handle 40 can be prevented from being carelessly detached from the clamper 20. .

  Further, since the slider body 11, the clamper 20, and the handle 40 are formed of a resin material, the slide fastener slider 10 can be manufactured at a low cost and at a low cost. Furthermore, since the pull handle 40 can be attached and exchanged later, it is possible to easily meet customer demands such as color and shape as needed. For example, the slide fastener slider 10 having many variations such as a two-tone color in which the slider body 11 and the handle 40 have different colors can be easily obtained.

  As described above, according to the slide fastener slider 10 of the present embodiment, the other end portion of the clamper 20 has the attachment portion 22 configured to attach the handle 40, so that the design according to the customer's request. By attaching the handle 40 to the clamper 20, the design can be improved. In addition, since the clamper 20 is provided with the protrusion 25 between the link portion 21 and the attachment portion 22, when the slider body 11 and the clamper 20 are automatically assembled, the clamper 20 is moved by the parts feeder depending on the direction of the protrusion 25. It is possible to automatically discriminate between the front and back surfaces. Therefore, only the clamper 20 in the proper direction can be supplied to the slider body 11, and the slider body 11 and the clamper 20 can be automatically assembled, and the slide fastener slider 10 can be mass-produced at low cost. In addition, since a projection part is provided between a link part and an attachment part, a projection part does not affect the rotation operation of a clamper, or attachment of a handle.

  Further, when the handle 40 is assembled to the clamper 20, the protrusion 25 of the clamper 20 is accommodated in the protrusion accommodating portion 46 of the handle 40, so that the protrusion 25 becomes inconspicuous, and the clamper 20 and the handle which are two different parts. 40 is obtained, and the design of the slide fastener slider 10 can be further improved.

  Further, since the protrusion 25 is provided between the link portion 21 and the mounting portion 22 of the clamper 20 and at a position that deviates from the center of gravity G of the clamper 20 in the longitudinal direction of the clamper 20, the clamper 20 is automatically moved by the parts feeder. When transporting, the clamper 20 rotates with the protruding portion 25 for catching as the central axis and the gravity center position G side down, so that it can be automatically adjusted to the appropriate direction, improving the operating rate of the automatic assembly machine. Can be made.

  Further, the attachment portion 22 of the clamper 20 includes an insertion portion 28 that is inserted into a clamper accommodating portion 43 formed on the handle 40, and an extension that extends in a direction opposite to the link portion 21 from the base portion 36 of the insertion portion 28. A locking piece 29 having a locking protrusion 31 formed at the leading end of the protruding portion 30 and the extending portion 30 is provided. A recess 32 is provided at the boundary between the extension 30 and the locking projection 31. As a result, when the clamper 20 is painted, the paint applied to the boundary portion between the extending portion 30 and the locking protrusion 31 accumulates in the recess 32 as a coating film, and the locking hole between the locking protrusion 31 and the handle 40 is retained. The angle shape of the abutting surface with 45 is maintained, the coupling strength between the clamper 20 and the handle 40 is maintained, and the handle 40 is securely locked to the clamper 20.

  Further, according to the slide fastener slider 10 of the present invention, the surface 33 of the insertion portion 28 on the side opposite to the locking projection 31 is a plate of the insertion portion 28 as it goes from the base portion 36 to the direction opposite to the link portion 21. Since the thickness t is an inclined surface that gradually increases, when the bending force is generated toward the protrusion side starting from the vicinity of the step 34 of the clamper 20, the insertion portion 28 and the handle 40 are compared to the case where there is no inclined surface. The contact surface is secured, the sliding is prevented by the frictional resistance, and the puller 40 can be prevented from being detached from the clamper 20.

In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably.
For example, in the above description, it has been described that the clamper 20 is coated as necessary. However, the resin material may be molded to a desired color before molding.
Moreover, although the protrusion accommodating part 46 was demonstrated as a substantially U-shaped notch, you may form the inner surface of the clamper accommodating part 43 so that it may have a thin wall part which covers the upper surface of the protrusion 25. The protrusion 25 may not be visible from the outside of the handle 40. Thereby, since the projection part 25 is hidden inside the handle 40, it looks good and the design is further improved.
Further, as in the present embodiment, the slider body 11 having the handle attachment portion 18 includes at least a pair of front and rear attachment column portions 18a and 18b, and a cover 18c is engaged with the attachment column portions 18a and 18b, thereby pulling the handle. The mounting pillar 18 may be configured, and one end portion extends from the upper blade 14 and the clamper 20 is assembled by caulking the other end portion in a state where the shaft portion 23 of the link portion 21 is accommodated. It may have a pull handle attachment column 18.
