Description

[Detailed description of the invention] This invention is a slider for slide fasteners, and in particular relates to a slider that uses a pole chain as the pull of the slider.The purpose of this invention is to attach the pole chain as a pull with a simple operation. To provide a slider having a structure that can be attached reliably and firmly.

This type of slider uses a handle that combines a pole chain and a clamper. Conventionally, as a means of attaching the pole chain to the clamper, a C-shaped support is formed at the rear end of the clamper. On the other hand, a pole chain is made by connecting each ball like a rosary with a connecting line with flanges on both ends.One ball at the tip is removed and the remaining connecting line is attached to the C-shaped support part of the clamper. There is one that can be installed by passing it through and tightening the support part.

Generally, this work is done by hand, and when using this method, it takes time and effort to remove each ball.Also, since only the collar of the connecting wire is engaged with the support, the strength against tension is limited. was weak.

This invention was devised to solve the above-mentioned conventional drawbacks.The structure of the invention will be explained with reference to an example.In Fig. 1, 1 is a slider body, 2 is an automatic stop device, and T is a clamper 3. As shown in Figures 2 to 4, the clamper 3 is made of a wooden board with a circular part extending thinner to one side when viewed from the front, and the circular part is the front end. A window hole 5 is opened in the front end portion of the clamp portion 6 to form a clamp portion 6 that engages within the automatic stop device 2.

Furthermore, a slit 7 is provided from the window hole 5 to the rear end of the clamper 3 so as to communicate with the window hole 5, and a small circular hole 8 is formed at the rear end of the slit 7.
The rear end is semicircularly curved.

On the other hand, the pole chain 4 has a plurality of balls 9 at both ends.
(not shown) connected by a connecting line 10,
The illustrated chain 4 connects the last ball 9b to another ball 9.
It has a larger diameter.

Therefore, to explain the related structure between the clamper 3 and the pole chain 4, the window hole 5 of the clamper 3 is formed to a size that allows at least one ball 9 of the pole chain 4 to pass through. The continuous slit 7 and small hole 8 are sized to allow the connecting wire 10 of the pole chain 4 to pass through.

Then, the ball 9a at the front end of the pole chain 4 is passed through the window hole 5, and the connecting line 10a connecting this ball 9a and the next ball 9 is guided from the window hole 5 through the slit 7 to the small hole 8, and then the clamper 3, that is, the part where the slit 7 is provided, is tightened so that the slit 7 is closed, and the ball chain 4 is attached to the rear end of the clamper 3, and both balls 9,
It is fixed with the clamper 3 sandwiched between the two.

This invention has the above structure, and the clamper 3 is assembled into the slider body 1 when the slider is assembled.When attaching the pole chain 4 to the assembled clamper 3, as shown in FIG. Keep the slider body 1 upright and the clamper 3 horizontally to widen the window hole 5, pass the ball 9a at the front end of the pole chain 4 through the window hole 5, and connect the connecting line 10a following the ball 9a to a slit. 7 and guide it to the rear end of the clamper 3.

At this time, in the case where the rear end of the clamper 3 is curved as in the embodiment, the pole chain 4, which is fitted in an upright position, is laid down horizontally as shown in FIGS. 5 and 6.

After fitting in this way, as shown in FIGS. 7 and 8, the rear end of the clamper 3 having the slit 7 is crimped to close the slit 7, thereby attaching the pole chain 4 to the clamper 3 in a manner that cannot be removed. It is something that can be done.

As described above, the slider for slide fasteners according to this invention has a window hole through which the ball of the pole chain can pass through at the front end of the clamper that is combined with the slider body, and extends from the window hole to the rear end of the clamper. By forming a slit, passing a ball through the window hole, passing a connecting line continuous with the ball through the slit, moving it to the rear end of the clamper, and crimping the rear end of the clamper where the slit is provided, the pole chain Since the clamper is placed between the two balls, when the slider slides, the tensile force applied to the pole chain is stopped by the frontmost ball that passes through the clamper, which increases not only the mounting strength but also the durability. It is an excellent puller.

In addition, when attaching the pole chain to the clamper, even if the clamper is built into the slider body, the ball can be inserted through the window hole of the clamper, the connecting wire passed through the sleeve, and the pole chain can be attached by crimping. This eliminates the need to remove one ball and allows for reliable installation with simple operations.
