Description

[Detailed Description of the Invention] The present invention relates to a dial structure for a wristwatch. The present invention relates to a composite dial plate that is a dial plate made by combining two or more types of dial plates, among dial plates that use members such as metals, precious stones, tools, wood, and glass.

A conventional composite member dial plate employs a structure in which the members are individually fixed on the dial substrate with an adhesive or the like without engaging with each other. As a result, gaps are created at the boundary surfaces between different types of members due to variations in the processing dimensions of the respective members, which is a factor that impairs the aesthetic appearance. Furthermore, it has not been possible to put into practical use a composite dial plate that combines members that cannot be adhesively fixed because there is no engagement relationship between different types of members.

The present invention eliminates such drawbacks by providing slopes for joining different members on the dial base, and inserting an elastic material between one member and the base to join the different members. The dial structure is characterized by an elastic force acting on the surface.

The purpose of the present invention is to improve the aesthetic appearance by minimizing the gap between the joining surfaces of dissimilar parts.

Another purpose of the present invention is to make it possible to fix components that cannot be fixed by gluing, brazing, etc. due to their strength and performance onto the dial base from the engagement relationship between the joining surfaces of dissimilar components. .

This will be explained below based on the drawings.

FIG. 1 is a partial cross-sectional perspective view showing a conventional dial structure, in which a member A3 and a member B4 are placed on a dial base 1.
is fixed by the joining member 2 or 5. Member A and member B have no bonding surfaces and are fixed to each other by bonding members.

Therefore, in order to combine parts A and B and install them on the dial base, it is necessary to consider the gap 6 in the design, which takes into account variations in processing dimensions, and this becomes a factor that impairs the aesthetic appearance. Ta. Furthermore, since both member A and member B need to be fixed on the dial base using joining members, members that cannot be joined due to strength and performance reasons cannot be used, which limits the variety of composite member dials.

FIGS. 2 and 3 are representative examples of the dial structure of the present invention. In FIG. 2, a member A13 made of nickel silver is fixed on a dial base 11 made of brass with a joining member 12 made of double-sided tape. A resilient material 15 made of rubber, synthetic resin, etc. is provided between the member B14 made of precious stone such as onyx and the dial base 11, and the member B14 is constantly resilient in the direction of the arrow 17. The member A13 and the member B14 have slopes 16 that are combined with each other on the joint surfaces of dissimilar materials, and support the elastic force of the member B14.

In FIG. 3, an aluminum member B24 is fixed onto a plastic dial base 21 with an adhesive bonding member 22. As shown in FIG. A resilient material 25 made of rubber, synthetic resin, etc. is provided between the member A23 made of glass and the dial base 21, so that the member A23 is always resilient in the direction of the arrow 27. The member A23 and the member B24 are slopes 2 that are combined with each other on dissimilar joint surfaces.
6 and supports the elastic force of the member A23.

With this structure, the composite member dial plate has minimal gaps between the joining surfaces of different members even if variations occur in the working dimensions of members A and B, and the appearance is improved. Furthermore, even if one of the dissimilar members cannot be joined due to strength or performance reasons, the structure allows the combination to be used as a composite dial plate, contributing to the expansion of the variety of dial plates.

It goes without saying that the present invention can be applied to other composite dial plates of irregular shapes and composite dial plates of three or more types.
