JPS601609Y2 - Combined structure of watch case and band - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a coupling structure between a breech-type watch case and a band, which has a protruding shelf at the bottom of the scissors.

The standard external shapes of conventional watch cases can be roughly divided into two types.

One of them is a very common shape with a transparent iron machete, which is commonly referred to as the 1-iron leg gnat, and the other is a type with an eaves attached to the top of the scissor mata part, which are widely known. There is.

Furthermore, most of the methods for attaching bands to the above two types of watch cases generally involve using a spring bar.

Also, watch cases that can be freely attached using this rod have a thickness of 10. It is limited to those around orrrIIt, with sufficient thickness in the breech part, and with a band attachment hole provided inside the breech part.

To explain the mounting structure in more detail, in the former case, a shielding metal fitting called a tip is attached to the connecting part of one end of the band, and a spring bar is inserted through the spring bar to attach the band body to the breech of the gun. The protrusions on the back of the lead metal fittings served to prevent the band from over-rotating.

There is also a type in which a spring bar is inserted into a pipe fixed to the lower surface of the band tip without using a scissors fitting, but this creates a gap at the connection part, which is undesirable in terms of appearance.

On the other hand, although the latter has the advantage of not having to block the iron joints like the former, the design is uniform and lacks freshness.

In addition, as watches have become thinner and more fashionable recently, in order to meet the demand for diversification of thin watch designs, there has been a demand for a watch with a simple breech-type general shape and a design that allows a thin mesh band, etc. to be attached directly to the watch. It has been.

However, the thickness of the watch case is 6. - In the case of a thin case within 200 mm, there is no space in the cross section to mount it in a direct connection so that the joint between the case and the band is not noticeable, so there is no space to mount it normally using a spring bar with a diameter of around 1.6 rrgn as in the past. It's starting to disappear.

In view of the above points, the present invention aims to provide a breech-type watch case with a simple structure in which a particularly thin mesh band or the like can be easily attached directly without using a spring bar.

This invention consists of a watch case with a protruding shelf on the band mounting part, and a band piece with a mounting bracket fixed to the bottom surface of the tip.
Bend a part of the mounting bracket downward to form a tongue piece,
By aligning the screw hole of the protruding shelf with the mounting hole of the tongue piece and fixing it with screws, the tongue piece is further pushed down and the tip of the band piece is rotated in the direction of the watch case. It is characterized by having its tip pressed into contact with the watch case.

Embodiments of the present invention will be described below with reference to the drawings.

In Figures 1 to 4, 1 is a watch case, 1a is a gun breech, 1b is a protruding shelf, 1c is a mounting screw hole, 2 is a band piece, 3
3 is a mounting bracket, 3ay 3b is a fixed portion, 3c is a mounting hole, and 4 is a mounting screw.

Next, the structure of each part will be explained.

In Fig. 1A and Fig. 3A, a protruding shelf 1b is provided on the iron bottom of the watch case 1 integrally with the watch case, and an arbitrary number of mounting screw holes 1c are provided in the protruding shelf 1b. There is.

At the opening in FIG. 1 and the opening in FIG. 3, a mounting bracket 3 is fixed to the back surface of the band piece 2 at fixed portions 3a and 3b by brazing or the like.

Further, a part of the mounting fitting 3 is bent to form a tongue piece 3d having a mounting hole 3c.

In the present invention, three tongue pieces 3d are provided, but this is done to make it easier to lift up after processing, and depending on the case, all three tongue pieces 3d may be integrated.

Next, the connection method will be explained with reference to FIGS. 3 and 4.

First, as shown in the opening of FIG. 3, the tongue piece 3d of the band piece 2 is positioned slightly upward on the fixed part 3a side as indicated by the chain line 3d' in the figure, and then the tongue piece 3d of the band piece 2 is placed on the protruding shelf 1b of the watch case 1 as shown in FIG. The band piece 2 is inserted into the bottom surface and crimped, and the mounting hole 3c is aligned with the mounting screw hole 1c of the watch case.Then, the band piece 2 is screwed and fixed with the mounting screw 4. Press the tip of the watch case against the watch case.

As mentioned above, the band is installed by placing the tongue piece 3d at the chain line 3d' as shown in the opening of Figure 3 and fixing it with screws. The connecting portion P of the band can be connected exactly without any gaps.

As mentioned above, according to the mounting structure of the present invention, the tip of the band is always pressed against the watch case due to the elasticity of the mounting bracket 3, so it is possible to connect the mesh band etc. directly to the breech type thin watch case. It has many practical effects such as simple structure, easy assembly, and cost advantages.
