Abstract

PURPOSE:To fix surely ornamental articles such as glass, crystal, etc. to a fixing member such as middle, band, etc. without deterioration in the lapse of time by fixing said ornamental articles of a timepiece to said fixing member via a metal deposited by evaporation. CONSTITUTION:A metal 3 which consists of Cr, ZnS, etc. and is deposited by evaporation is formed on the surface of windshield glass 1 facing a middle 2 and the glass 1 is placed on the middle 2. A laser light 4 is irradiated to the metal 3 from the top surface of the glass 1 to melt and weld the metal 3. The metal 3 is similarly formed to an ornamental article 5 such as glass, crystal or the like and the article 5 is fixed to the middle 2 by the laser 4 in the case of fixing said article 5 to the middle 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a method for fixing an ornament such as a crow or a crystal to a fixing member such as a body or a band.

[Background of the Invention] Conventionally, for example, in a watch, the body and the windshield are generally fixed using an adhesive. However, since the adhesive changes over time, it has a drawback of being inferior in reliability.

[Object of the Invention] The object of the present invention is to provide highly reliable and reliable fixing to H(
The object of the present invention is to provide a method for fixing decorative items.

[Embodiments of the Invention] Hereinafter, one embodiment of the present invention will be described with reference to FIG. 1. In six embodiments, a windshield 1 is fixed to a body 2. First, a vapor-deposited metal 3 made of Cr, ZnS, etc. is formed on the surface of the windshield l that corresponds to the body 2. Next, windshield glass 1 is attached to body 2.
is mounted, and the laser 4 is irradiated onto the vapor-deposited metal 3 from the first side of the windshield glass 1 to melt the vapor-deposited metal 3. As a result, the metal fitting 3 is welded to the body 2.

In this way, the windshield l is attached to the body 2 through the metal attachment 3.
Since it is fixed in place, deterioration over time does not occur.

Further, since the vapor-deposited metal 3 is welded to the body 2 and is internally pressed, the fixation is reliable.

In addition, in the illustrated embodiment, the laser 4 is irradiated to the part of the vapor-deposited metal 3 corresponding to the city surface 2a of It-12.
The horizontal surface 2b) may be irradiated with the laser 4. Further, although the vapor-deposited metal 3 is formed on the entire surface of the portion corresponding to the body 2, it may be formed only on the portion to be fixed, that is, the portion to which the laser 4 is irradiated. In addition, the vapor-deposited metal 3 formed on the lower surface of the windshield 1 is formed up to the parting part, and by giving it an older parting function,
There is no need for a parting section.

FIG. 2 shows another embodiment of the invention. This embodiment shows a case in which an ornament 5 such as glass or crystal is fixed to the bracket 2.

That is, the vapor-deposited metal 3 is formed on the ornament 5 in the same manner as in the previous embodiment, and the ornament 5 is fixed to the body by the laser 4. Even if formed in this way, the same effects as in the embodiment described above can be obtained. In this case, it is preferable that the windshield crow 1 and the IP 12 be fixed in the same manner as in the above embodiment, but they may be fixed using an adhesive as in the conventional method.

FIG. 3 shows yet another embodiment of the invention. In this embodiment, a groove 20 is provided at the corner of the body 2, a brazing material 6 is placed in this groove 2C, and a laser 4 is irradiated onto the brazing material 6 to form a jig 12 and an ornament 5.
It becomes fixed.

When formed in this manner, the brazing material 6 is melted by the laser 4 and flows between the vapor deposited metal 3 and the body 2, making the fixation more reliable. in this case.

By irradiating the laser 4 not only to the brazing filler metal 6 but also to the base metal 3 where the brazing filler metal 6 is not placed, the reliability of the 1M constant is further increased.

[Effects of the Invention] As is clear from the above description, according to the present invention, in a method for fixing an ornament such as glass or crystal to a fixing member such as a body or a band, 1) the fixing member of the ornament described in 1j. A vapor-deposited metal is formed on a part or the entire surface corresponding to
Since the vapor-deposited metal is irradiated with a laser to melt the vapor-deposited metal and the ornament is fixed to the fixing member via the vapor-deposited metal, reliable fixation can be obtained without deterioration over time.
