Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a timepiece in which a plurality of beautiful pieces, such as precious stones, which have been pre-formed and are arranged side by side and fixed on a dial substrate. Concerning a composite dial for use.

[Conventional technology]

Conventional watch composite dials have a plurality of aesthetically shaped pieces, such as precious stones, arranged in parallel on the surface of a dial substrate.
It was fixed by gluing or caulking.

[Problem that the invention seeks to solve]

However, in the above-mentioned conventional technology, it is impossible to eliminate the gap formed between one small piece and an adjacent small piece due to the processing accuracy of the molded small piece or the positional accuracy when fixing it on the surface of the dial substrate. It is impossible to do so, and the dial substrate is visible through the gap, significantly degrading the aesthetic appearance. Also, other fluid substances,
For example, the method of filling with plastic resin has the problem of requiring a huge number of processing steps and increasing costs.

The present invention is intended to solve these problems, and its purpose is to prevent the gaps between the small pieces on the surface of the dial board from deteriorating the aesthetic appearance, and to make the gaps appear as if they were the same. To provide a composite dial for a watch which can give an appearance giving the illusion that it is not there.

[Means for solving problems]

The composite dial plate for a timepiece of the present invention is a composite dial plate for a watch, in which a plurality of small pieces having an aesthetic appearance are arranged side by side and fixed on the surface of a dial plate substrate, wherein at least the plurality of small pieces on the surface of the dial plate substrate are fixed. It is characterized in that printing is applied to portions corresponding to the positions of the gaps between the pieces that are created by arranging and fixing them side by side.

〔Example〕

Hereinafter, the present invention will be explained based on examples.

Embodiment 1 In FIG. 1, a is a plan view and b is a cross-sectional view. A dial board 1 made of brass with a thickness of 0.3 mm is pressed into a predetermined shape, and a mounting pin 5 is attached to the machine body.
Weld and apply nickel plating to this surface, weld a small piece to this surface, apply nickel plating to this surface,
A black print 4 having a width of 1 mm and having approximately the same shape as the gap 6 formed between the small piece 2 and the adjacent small piece 2 (wider than the gap) is applied. Next, a small piece 2 of Epoquin adhesive 3 for fixing is applied to the surface of the dial board 1 from which the black printing part has been removed, and the small piece 2 is pressed out in a predetermined shape. When a small piece of nickel silver material 2 with a thickness of 0.2 mm is glued and fixed,
The gap 6 is not noticed, and the dial is finished as if it were one piece with different aesthetics.

Example 2 In Fig. 2, a is a plan view and b is a cross-sectional view thereof.A concave shape with a depth of 0.03 mm for fixing different precious stone pieces 2 and 2' is placed on a brass dial substrate 1 with a thickness of 0.4 mm. It has approximately the same shape (wider than the gap) as the gap 6 that occurs between the adhesive groove 8 and the precious stone pieces 2, 2', and has a width of 1
After coining a concave printing groove 7 with a depth of 0.03 mm and pressing it into a predetermined shape, a mounting pin 5 to the machine body is welded and nickel plated.

Next, black printing 4 is applied to the printing groove 7 of the dial board 1 with a thickness of 0.01 mm, and then the adhesive groove 8 is coated with black printing 4.
Apply epoxy adhesive 3 to a thickness of 0.05 mm and adhere different precious stones 2 and 2'. At this time, the black printing 4 prevents reflection from the dial substrate 1, and the concave printing grooves 7 serve to prevent the black printing 4 from being scraped by the corners of the precious stone pieces 2, 2'. In addition, the concave adhesive groove 8 is used when the precious stone pieces 2, 2' are fixed with adhesive.
It serves to prevent the adhesive from flowing out and adhering to the black print 4 or coming out on the side of the dial board 1.

The dial plate with precious stones combined in this way creates a dial plate with a high-quality appearance in which the different precious stones look as if they were one piece of precious stone, with no gaps being noticed at all.

In Examples 1 and 2, the printing width of the black printing 4 was made to be approximately the same shape, which was wider than the gap 6 between each small piece.
Since it is sufficient to be able to cover up the background of the print, the shape of the printing width may be any shape as long as it is equal to or larger than the gap 6.

〔Effect of the invention〕

As described above, according to the present invention, printing is performed on the portions of the surface of the dial substrate that correspond to the positions of the gaps between the small pieces created by arranging and fixing at least a plurality of small pieces side by side. , since the printing part covers the background of the dial board surface that was conventionally visible through the gaps between each small piece, and the printing color can be freely selected, it can be used as a new design element not found in the conventional technology, and each small piece can be used as a new design element. In combination with this, it has the effect of providing a wide variety of excellent patterned appearances.

In other words, (1) By arbitrarily selecting the printing color on the dial board for small pieces, large or small, or simple to complex shapes, we can make the gaps invisible;
The result is a finish that looks like a series of small pieces.

(2) By using various printing colors, it is possible to create subtle hues in the gaps, make the small pieces stand out, or make the printed color stand out to create an appearance that balances the small pieces.

It has the following effects.

Claims (1)

[Claims] 1. In a composite dial for a timepiece in which a plurality of aesthetically pleasing small pieces are arranged and fixed on the surface of the dial substrate, the above-mentioned appearance is caused by placing and fixing at least the plurality of small pieces on the surface of the dial substrate side by side. A composite dial for a watch characterized by printing on portions corresponding to the positions of the gaps between each small piece.
