Description

Zipper slider

The present invention relates to a slider for a slide fastener. In particular, it relates to a slider for a slide fastener that can smoothly perform a stop operation of a slider and a switching operation of a slide operation.

At present, the zipper is used in various aspects such as a seat of a car or a windbreaker, a substitute for a shoelace, and the like. However, if a force is applied to the zipper due to vibration or movement from the vehicle or vibration applied during walking, the slider of the swaying state may contact the slider body to generate a contact sound, or the zipper may be pulled by the chain cloth. The lodging state is erected. If the pull tab is erected from the lodging state, the stop mechanism of the slider for stopping the pawl is released, and the slider is slid.

In order to prevent the contact sound or the slider from being released from the stop state as described above, a slide fastener having a configuration in which the pull tab is not simply erected when the slider is stopped, and the pull-down state of the pull-tab is locked is proposed. . As such a slide fastener for slide fasteners, for example, the inventions described in Patent Documents 1 to 3 have been proposed.

Further, a pair of cantilever engaging pieces 68 are extended toward the side of the rotating shaft 66 in the window portion 69 of the tab 65. The pair of cantilever locking pieces 68 are configured to extend in parallel with the rotation shaft 66. The pull-tab releasing portion 64 is formed with a detaching head portion 64a that is detached between the pair of cantilever locking pieces 68. The detachment head portion 64a is configured to protrude in the left-right direction of the slider, and is engaged with the pair of cantilever locking pieces 68 by the pull-tab releasing portion 64. In between, the pull-up state of the pull tab 65 is maintained.

When the pull tab 65 is laid down toward the rear side, the detachment head portion 64a is inserted between one of the elastic deformations and the cantilever engagement piece 68. Thereby, the pair of cantilever engagement pieces 68 and the pull-tab releasing column portion 64 are brought into engagement, and the pull-up state of the pull-tab 65 is maintained. When the pull tab 65 is raised from the lodging state, the engagement state between the pair of cantilever engaging pieces 68 and the pull-tab releasing column portion 64 is released. Then, the slider 60 can be slid by the operation of the pull tab 65.

The slide fastener for slide fasteners described in the patent document 3 (Japanese Patent Laid-Open Publication No. 2010/070744) is the prior art 3 of the present invention, and FIG. 15 is a perspective view showing the assembly of the slider before assembly. The configuration in which the pull-up state of the pull-tab 72 in the slide fastener for a zipper of Patent Document 3 is maintained is the same as that in Patent Document 2. In other words, the pull-tab releasing portion 77 that is erected on the upper end surface of the upper blade 71 is attached to and detached from the one of the window portions extending from the pull-tab 72 to the cantilever engaging piece 78.

In the case of the stop mechanism of the slide 70 that uses the pawl to be stopped, the structure of the stop pawl piece 67 that is provided on the rotary shaft 66 is used in the patent document 2. However, in Patent Document 3, the use of the plate spring is included. The configuration of the pawl body 73 is stopped.

In the illustrated example, the detachment head 24a that slides over the engaged portion 4 over one of the engaged portions 4 and the locking piece 24 is located below the engaged portion 4, In this state, the lodging state of the pull tab 20 is maintained.

The configuration of the detachment heads 5 and 24a is a configuration that protrudes to the outside in the illustrated example. However, the configuration of the detachment heads 5 and 24a is a detachment head as long as they can be engaged with each other. The surface shape of the abutting portions of the portions 5 and 24a can be configured to have a suitable surface shape.

In the above description, the configuration in which the pair of locking pieces 24 extend from the inner edge portion 23c of the window portion 23 in parallel to the side of the rotary shaft 21 has been described. However, other configurations may be adopted as the configuration of the pair of locking pieces. . In other words, as shown in FIG. 7, the pair of locking pieces 38 may be formed from the inner edge portions 23b and 23d of the window portion 23 so that the front end portions are close to each other and arranged to face each other. In the configuration in which the pair of locking pieces 38 are opposed to each other, the detachable head portion 38a can be formed at the end portion of each of the locking pieces 38. Further, the pair of locking pieces 38 can be detached from the side surface formed on the engaged portion 4 of the cover 2, respectively.

Next, when the assembling method of the slider 1 is described using FIG. 1, the rotary shaft 21 of the pull tab 20 is housed in the recessed portion 14a formed in each of the pair of pull tab pivot portions 14. After the rotary shaft 21 is housed in the recess 14a, the cover 2 is covered from above the upper blade 11 so as to cover the pair of tab pivot portions 14 from above by the narrow portion 3b. After the cover 2 is placed, the cover side wall 7 is pressed and pressed against the inner surface side from the outer surface side, and the cover 2 is fixed to the fixing post 15. The slider 1 can be assembled in the manner described above.

The plane of the assembled slider 1 is shown in Fig. 2. A cross-sectional view of III-III in Fig. 2 is shown in Fig. 3, and a side view of the slider 1 is shown in Fig. 4. In Fig. 6, a cross-sectional view taken along line VI-VI of Fig. 2 is shown. Further, Fig. 5 is a cross-sectional view showing the main part when the pull tab 20 is rotated from the state shown in Fig. 3 to the standing state.

As shown in Fig. 2, the plan view shape in the region covered by the wide portion 3a of the top plate 3 is configured to have substantially the same shape as the plan view shape of the upper blade 11 in the same region. Thereby, the area in the plan view shape of the wide portion 3a can be broadly formed, and the wide portion 3a can be configured as a part of the flap 11 as described above. Further, since the narrow portion 3b is configured to extend rearward from the wide portion 3a and cover the pair of tab pivot portions 14, the upper surface of the cover 2 can be a top plate including the wide portion 3a and the narrow portion 3b. 3 is configured as a smooth flat surface, and the pair of tab pivot portions 14 can be exposed to the outside by the narrow portion 3b.
