Description

[Detailed explanation of the idea] This invention relates to buckles for watch bands, etc.

Conventionally, various types of buckles of this type have been developed and put into practical use.

By the way, watch bands and the like to which this type of buckle can be attached have a high value as accessories, so there is a strong demand from the general public for particularly good decorative ones, that is, ones with a high design quality. Naturally, the buckle attached to the band or the like is of a type that does not impair the design of the band itself.

On the other hand, it is also necessary that the function as a buckle is excellent, that is, the attachment/detachment operation force is easy, and these operations can be performed reliably.

This idea was made in view of the above circumstances,
The purpose is to provide a buckle for a watch band or the like that is easy to attach and detach the band to the buckle, works reliably, and has an excellent design.

Hereinafter, one embodiment of this invention will be described in detail with reference to the drawings.

1 to 5 show an embodiment of this invention, and the buckle of this invention consists of a first connecting piece 1, two second connecting pieces 2, 2, and a third connecting piece 3. Become.

The first connecting piece 1 has a connecting part 4 for connecting the band 10 at one end 1a, and has convex edges 1b and l on the left and right sides of the bottom surface of the bottom.
It has b.

Further, the second connecting pieces 2, 2 are connected to the other end IC of the first connecting piece 1.
One end portions 2a, 2a are connected to each other by a first connecting pin 11, and the storage space S formed between the convex edges 1b, 1b of the first connecting piece 1 can be folded in freely.

On the other hand, the third connecting piece 3 has a connecting part 5 that connects the band 10 at one end 3a, and the other end 3b is connected to the other end 2b of the second connecting piece 2.2 with a second connecting pin 12. connected with
The storage space left between the convex edge 1b and the second connecting piece 2 by folding the second connecting piece 2.2 into the first connecting piece 1 (in this case, the two second connecting pieces 2, 2) so that it can be folded freely.

The connecting portions 4 and 5 are provided with pin holes 4a and 5a, respectively, through which pins 4b and 5b can be inserted to connect the connecting pieces 1 and 3 to the band 10.10. ing.

Further, a locking groove 6 is provided in the width direction at one end 3a of the third connecting piece 3, into which the first connecting pin 11 is fitted and locked.

A pipe 13 having a protrusion 13a protruding toward the center is fitted to the first connecting pin 11 by fitting the protrusion 13a into a groove 11a carved on the outer periphery of the first connecting pin 11. The distance between the two second connecting pieces 2, 2 is regulated and the first connecting pin 11 is prevented from being pulled out in the axial direction.

Reference numeral 7 designates an adjustment groove provided for adjusting the locking force of the pipe 13 of the first connecting pin 11 with respect to the locking groove 6 by deforming the locking groove 6 with a screwdriver or the like, and 8 denotes a third connecting groove. This is a window hole provided in the first connecting piece 1 to expose a portion of the piece 3 to the outside.

The method of using the buckle configured as described above is almost the same as that of a conventional three-fold buckle. Connecting piece 1
The first connecting pin 11 may be fitted into the locking groove 6 by pressing one end 1C of the pin.

In this way, the second connecting pieces 2, 2 are connected to the storage space S of the first connecting piece 1.
Furthermore, since the 3' connecting piece 3 is folded and locked between the second connecting pieces 2, 2, it does not become bulky in the thickness direction.

In addition, the one in the figure has two second connecting pieces, and one
Although the third connecting pieces of the books are connected, it is also possible to use one second connecting piece and connect two third connecting pieces to this.

As described in detail above, the buckle of this invention includes a first connecting piece that is provided with a connecting part that connects the band at one end and has convex edges on the left and right sides of the lower surface, and this first connecting piece. a second connecting piece having one end connected to the other end by a first connecting pin and configured to be foldable into a storage space formed between the convex edges of the first connecting piece; and a band at one end. The other end is connected to the other end of the second connection piece by a second connection pin, and the convex edge and the second connection are made by folding the second connection piece into the first connection piece. and a third connecting piece configured to be foldable into the storage space left between the pieces, and in the folded state, both the second connecting piece and the third connecting piece are stored in the storage space of the first connecting piece. As a result, the appearance in the folded state is simple and has an excellent design, and therefore has excellent effects such as improving the design of the entire watch band.
