Description

Slider for slide fastener

The present invention relates to a slider for a slide fastener. In particular, the present invention relates to a slider for a slide fastener capable of smoothly switching between a slider stop operation and a slide operation.

Currently, slide fasteners are widely used for sportswear such as car seats, windbreakers, and shoe laces. However, if force is applied to the slide fastener due to vibration from the car, vibration during exercise or walking, etc., the swinging puller touches the slide body and generates a contact sound, or the puller tape is in a lying state due to the fastener tape May be launched. When the puller rises from a lying state, the slider stop mechanism using the stop pawl is released, causing the slider to slide.

In order to prevent the generation of such contact noise and the release of the slider from the stop state, the slide fastener has a structure that locks the fall state of the puller so that the puller does not stand up easily when the slider stops. A slider has been proposed. As this type of slide fastener slider, for example, inventions described in Patent Documents 1 to 3 have been proposed.

As a slide fastener slider described in Patent Document 1 (Registered Utility Model No. 3160840), as a conventional example 1 in the present invention, FIG. . As shown in FIG. 13, a cantilever-shaped pulling attachment column 52 is disposed on the upper surface of the upper blade 51. The front end portion 52F of the pull handle attaching column 52 is fixed to the upper blade 51, and the rear end portion 52R is configured as a free end. The shaft portion 56 of the handle 54 is accommodated in the handle attachment space 53 of the handle attachment column 52. The puller attachment space 53 is formed in an intermediate portion between the front end portion 52F and the rear end portion 52R of the puller attachment column 52.

The both ends of the shaft part 56 and the grip part 55 of the handle 54 are connected by a pair of leg parts 57. On the inner side surfaces in the width direction of the pair of leg portions 57, arc-shaped convex portions 57a that protrude inward in the width direction are formed. When the puller 54 is tilted forward or backward, the convex portions 57a come into contact with the side surfaces of the puller attachment column 52, so that the pair of leg portions 57 are elastically deformed in the direction in which the space between the pair of leg portions 57 spreads. Then, the side surface of the pull handle attachment column 52 can be elastically held by the convex portion 57a.

By sandwiching the side surface of the pull attachment column 52 by the pair of convex portions 57a, the pull handle 54 can be held in a state where it is lying forward or backward. When the handle 54 is erected from the lying state, the holding state of the handle 54 by each convex portion 57 a is released, and the slider 50 can be slid by the operation of the handle 54.

FIG. 14 is a perspective view of the slide fastener slider described in Patent Document 2 (International Publication No. 2009/130771 pamphlet) as a conventional example 2 of the present invention with the handle raised. As shown in FIG. 14, on the upper surface of the substantially central portion of the upper wing plate 61, a pivotal support portion 62 that pivotally supports the rotation shaft 66 of the pull handle 65 is provided on the left and right. Further, a claw hole 63 is formed between the pair of pivotal support parts 62, and when the handle 65 is lying down, a stop claw piece 67 protruding from the rotation shaft 66 is inserted into the claw hole 63.

On the upper surface of the rear end side of the upper wing plate 61, a puller engagement / disengagement column part 64 for maintaining the fall state of the puller 65 is erected. In addition, a pair of cantilever locking pieces 68 are extended in the window 69 of the handle 65 toward the rotating shaft 66 side. The pair of cantilever locking pieces 68 are configured to extend in parallel toward the rotation shaft 66, and the handle engaging / disengaging column portion 64 is engaged / disengaged between the pair of cantilever locking pieces 68. An engagement / disengagement head 64a is formed. The engagement / disengagement head 64a is configured in a shape that swells in the left-right direction of the slider, and when the handle engagement / disengagement column part 64 is engaged between the pair of cantilever locking pieces 68, the handle 65 falls down. State is maintained.

When the handle 65 is laid down on the rear side, the engaging / disengaging head 64a is inserted between the pair of elastically deformed cantilever locking pieces 68. As a result, the pair of cantilever locking pieces 68 and the pull handle engagement / disengagement column portion 64 are brought into an engaged state, and the fall state of the pull handle 65 is maintained. When the handle 65 is erected from the lying state, the engaged state between the pair of cantilever locking pieces 68 and the handle engaging / disengaging column part 64 is released. Then, the slider 60 can be slid by the operation of the handle 65.

FIG. 15 shows a perspective view of a slide fastener slider described in Patent Document 3 (International Publication No. 2010/070744 pamphlet) as Conventional Example 3 in the present invention before assembly of the slider. The configuration for holding the lying state of the puller 72 in the slide fastener slider of Patent Document 3 is the same as the configuration of Patent Document 2. That is, the handle engaging / disengaging portion 77 standing on the upper surface of the rear end side of the upper blade 71 is engaged / disengaged between a pair of cantilever locking pieces 78 extended to the window portion of the handle 72. .

A pair of locking pieces 24 are provided on the inner edge 23c of the window 23 so as to protrude toward the rotating shaft 21 and are arranged in parallel to each other. The pair of locking pieces 24 is formed in a cantilever shape, and an engagement / disengagement head 24a is formed at the front end portion of each locking piece 24 on the mutually opposing surfaces. When the pull handle 20 is tilted backward, the engaging / disengaging head 24a can be engaged with the engaging / disengaging head 5 of the engaged portion 4 formed on the cover body 2. Then, the engaged portion 4 is elastically sandwiched between the engaging / disengaging heads 24a of the pair of expanded locking pieces 24.
In the illustrated example, the engagement / disengagement heads 24a of the pair of locking pieces 24 that have passed over the engaged portion 4 while sliding on the engaged portion 4 are located below the engaged portion 4, and this state The hold state of puller 20 is maintained.

As the configuration of the engaging / disengaging heads 5 and 24a, in the illustrated example, a configuration bulging outward is shown, but the engaging and disengaging heads 5 and 24a may be configured to engage with each other. For example, the surface shape of the contact portion of the engagement / disengagement heads 5 and 24a can be configured to have an appropriate surface shape.

In the above description, the configuration in which the pair of locking pieces 24 are extended from the inner edge portion 23c of the window portion 23 in parallel to the rotating shaft 21 side has been described, but the configuration of the pair of locking pieces is as follows. Other configurations can be employed. That is, as shown in FIG. 7, the pair of locking pieces 38 can be configured in an arrangement configuration in which the front end portions are opposed to each other from the inner edge portions 23 b and 23 d of the window portion 23. In the arrangement configuration in which the pair of locking pieces 38 are opposed to each other, an engaging / disengaging head 38 a can be formed at the tip of each locking piece 38. The pair of locking pieces 38 can be engaged / disengaged with respect to the side surface of the engaged portion 4 formed on the cover body 2.

Next, a method for assembling the slider 1 will be described with reference to FIG. 1. The rotating shaft 21 of the pull handle 20 is housed in the recesses 14a formed in the pair of pull handle pivot support portions 14, respectively. After the rotating shaft 21 is housed in the recess 14a, the cover body 2 is covered from above the upper wing plate 11 so that the pair of pulling pivot support portions 14 are covered with the narrow width portions 3b from above. After covering the cover body 2, the cover body side wall 7 is pressed and crimped from the outer surface side toward the inner surface side to fix the cover body 2 to the fixed column 15. In this way, the slider 1 can be assembled.

2) A plan view of the assembled slider 1 is shown in FIG. 3 is a sectional view taken along the line III-III in FIG. 2, and a side view of the slider 1 is shown in FIG. FIG. 6 shows a sectional view taken along line VI-VI in FIG. FIG. 5 shows a cross-sectional view of the main part when the handle 20 is turned upright from the state shown in FIG.

As shown in FIG. 2, the planar shape in the region covered with the wide portion 3a of the top plate 3 is configured to be substantially the same as the planar shape of the upper blade plate 11 in the same region. Accordingly, the area of the wide portion 3a in the planar shape can be configured to be wide, and the wide portion 3a can be configured as a part of the upper wing plate 11. Further, since the narrow width portion 3b is configured to extend rearward from the wide width portion 3a and cover the pair of puller pivot support portions 14, the upper surface of the cover body 2, that is, the wide width portion 3a and the narrow width portion 3b. The top plate 3 can be configured as a smooth flat surface, and the pair of pulling pivot support portions 14 can be covered with the narrow width portion 3b.

Further, in a state where the pulling handle 20 is tilted backward, the pair of locking pieces 24 are engaged with the engaged portion 4, and the falling state of the pulling handle 20 can be maintained. As shown in FIG. 6, the engagement / disengagement head 24a formed on the engagement surface of the pair of puller pivot support portions 14 and the engagement / disengagement head 5 formed on the engagement surface of the engaged portion 4 are slid. An engagement state can be reached by overcoming the contact state. In order to overcome the sliding contact state between the engagement / disengagement head 24a and the engagement / disengagement head 5 and to bring it into the engagement state, it is possible only to apply an appropriate operating force to the rotation of the pull handle 20. On the other hand, even when releasing from the engaged state, it can be performed only by applying an appropriate operating force to the rotation of the pull handle 20.

In order to rotate the puller 20 from the lying down state to the standing state, the inner surface shape of the window portion 23 of the puller 20 is formed to have a width dimension in which the narrow portion 3b of the cover body 2 can be inserted when the puller 20 is rotated. ing.

Further, as shown in FIGS. 3 and 4, the upper surface of the handle 20 and the upper surface of the engaged portion 4 in the lying state can be configured to be lower than the upper surface of the cover body 2. With this configuration, it is possible to improve the design of the slider 1 on the appearance, to improve the touch feeling, and to bring out the flatness of the slider 1. In addition, since the pair of puller pivot support portions 14 is covered with the narrow width portion 3b of the cover body 2, it is possible to prevent the pair of puller pivot support portions 14 from being exposed from the upper surface side of the slider body 10.

As described above, since the upper surface of the cover body 2 covering the pulling pivot part 14 can be configured as a smooth flat surface, the touch feeling can be improved and the flatness of the slider 1 can be produced. Moreover, since the cover body 2 can be shown as a part of the upper wing plate 11, the design on the appearance of the slider 1 can be greatly improved.

In this way, when the pull handle 20 is in the fallen state, the fall state of the pull handle 20 can be held by the engagement between the pair of locking pieces 24 and the engaged portion 4, and the stop claw piece 25 Coupled with the sliding stop function of the slider 1, the sliding of the slider 1 can be regulated in two stages.

Further, as shown in FIG. 3, the rotation shaft 21 of the pull handle 20 is blocked by the narrow width portion 3 b of the cover body 2 from slipping out of the recess 14 a of the pair of pull handle pivot portions 14. With this configuration, in order to prevent the rotation shaft 21 from coming off, it is not necessary to have a configuration in which the top portions 14b of the pair of puller pivot support portions 14 shown in FIG. The height position of the pair of pulling pivot support portions 14 storing the rotation shaft 21 can be configured to be at least a height position where the rotation shaft 21 can be stored. It can be configured lower than the tightening configuration. As a result, an increase in the height dimension of the slider 1 including the cover body 2 can be suppressed.

As shown in FIG. 5, when the handle 20 is rotated from the lying state to the standing state, the stop claw piece 25 inserted into the claw hole 16 retreats from the claw hole 16 and the cover body 2 is engaged. It contacts the inner surface 4a of the portion 4 or the inner surface of the narrow portion 3b of the top plate 3. Then, when the stop claw piece 25 comes into contact with the inner surface 4a of the engaged portion 4 or the inner surface of the narrow width portion 3b, the rotation amount of the handle 20 is restricted.

Moreover, at this time, since the stop claw piece 25 is covered with the cover body 2, the stop claw piece 25 is not exposed to the outside. Since the cover body 2 can prevent an obstacle from coming into contact with the stop claw piece 25, it is possible to prevent damage caused by the stop claw piece 25 coming into contact with the obstacle or the like.

The configuration for restricting the rotation of the pull handle 20 may be a configuration in which the rotation amount of the pull handle 20 is restricted by a part of the pull handle 20 and a part of the cover body 2 coming into contact with each other. For example, the window frame constituting the window portion 23 of the pull handle 20, that is, the inner edge portions 23b and 23d of the window portion 23 is in contact with the edge of the wide width portion 3a of the cover body 2 on the pull handle pivot portion 14 side. It is also possible to regulate the amount of rotation.
