JPS595370Y2 - Combined structure of watch case and band - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a coupling structure between a watch case and a band.

Conventionally, there are many types of coupling structures between a watch case and a watch band, depending on the shape of the band and the watch case.

Among these, there is a so-called direct bracelet structure in which the case and band are brazed together.

This structure allows the watch case and band to be integrated, making it possible to obtain an elegant bracelet watch, but it is difficult to braze the band to the watch case, and corrosion may occur after brazing. It has drawbacks.

Furthermore, with a direct-connection bracelet structure, if either the band or the case is damaged, the band and case must be replaced in full, which poses problems in terms of after-sales service.

The present invention has been improved in view of the above-mentioned drawbacks, and aims to provide a structure for connecting a watch case and a band, which looks like a bracelet in appearance and also allows the band to be replaced.

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

FIG. 1 is a perspective view of the watch case and band after they have been connected, FIG. 2 is a perspective view of the watch case and band before they are connected, and FIG. 3 is a sectional view taken along line III--III in FIG.

The main components of the present invention are: a watch case 1 having two protrusions 1a on the outer circumferential band attachment part; a band body 2 having a comb-shaped connecting part 2a at the tip; and a watch case 1 and a band body 2 connected to each other. It consists of a gun tip piece 3 that connects the above-mentioned parts, and a connecting member 4 that connects the parts.

A connecting hole 1b is formed in the leg portion 1a of the watch case 1, through which a connecting member 4 such as a spring bar or a solid hairpin is inserted.

The connecting portion 2a of the band body 2 is provided with a connecting hole 2b through which the connecting member 4 is inserted.

The scissors tip piece 3 has a side wall portion 3a and a flat plate portion 3b that face each other so as to cover the two leg portions 1a, and a connecting hole 3C through which the connecting member 4 is inserted is bored in the side wall portion 3a. The flat plate portion 3b is provided with a comb-like engaging portion 3d that engages with the connecting portion 2a of the band main body 2.

This meshing portion 3d is not provided with a hole such as a connecting hole.

To attach the band body 2 to the watch case 1,
Place the leg part 1a of the watch case 1 inside the gun tip piece 3,
Further, the connecting portion 2a of the band main body 2 is arranged between the leg portions 1a, and the connecting holes 1b, 2b, and 3C of each component are aligned on one axis.

Next, the hair pin connecting member 4 is inserted into the connecting holes 1b and 2.
b, 3C and connect the watch case 1, tip piece 3, and band body 2 to complete.

The watch case and band connected in this way are
As shown in the figure, a wristwatch with an integrated appearance and a high-class appearance is obtained.

In particular, since the square leg portion 1a of the watch case 1 is completely covered with the tip piece 3, the appearance from the side is also excellent.

Furthermore, since the three parts 1, 2, and 3 are connected by one connecting member 4, the width of the tip piece 3 can be made smaller, increasing the degree of freedom in design.

Furthermore, the connecting part connects three parts: the square foot part, the connecting part between the tip piece and the band body, and the connection between the tip piece and the connecting part is done by the comb-shaped part. Since they are in contact with each other and do not overlap one above the other, they do not become thicker.

Figure 4 shows a commercially available band 5 attached with a spring bar 6 after removing the scissors piece 3 and band body 2 shown in Figures 1 to 3.The structure of the present invention is also advantageous in terms of after-sales service. be.

Like a double chain, the present invention allows the tip piece to cover the corner leg of the watch case and can be attached to the watch case without any gaps, resulting in a directly connected bracelet-like watch.

In addition, the tip gun piece and the band body have similar shapes in appearance,
Since they are decorated with patterns, there is no sense of incongruity between the two.
