Description

In the present invention, holes or grooves are formed in at least a part of the main body, and the holes or grooves are filled with a colorant capable of producing, for example, a cloisonne-like pattern, and a plating layer is formed on the surface of the main body. , A method for manufacturing accessories such as eyeglasses, necklaces, bracelets, brooches, earrings, ankles, rings, watch sides or watch belts on which a coating layer such as a coating layer or a metal vapor deposition layer is formed, and accessories manufactured by this method. ..

Cloisonne, a type of colorant, has been used in traditional crafts since ancient times, and has the characteristic glassy transparency and texture, and has the characteristic of having subtle shades and luster that change intricately. Cloisonne-style paints containing epoxy as the main ingredient are known as colorants capable of producing such cloisonne-style patterns (hereinafter referred to as "cloisonne patterns"), such as eyeglasses, necklaces, bracelets, brooches, earrings, etc. It is used for any jewelry such as cloisonne, ring, watch side or watch belt. Then, by using such a cloisonne-style paint, it is possible to impart aesthetics and elegance to the accessory.

Taking advantage of such characteristics of cloisonne or cloisonne-like paint, various products with enhanced decorativeness such as plating, painting, and metal deposition have been developed.
For example, in Patent Document 1, after forming a shape pattern on the surface of a metal plate with a wired cloisonne, a wireless cloisonne, a transparent cloisonne, or the like, the exposed metal surface other than the cloisonne is plated with nickel, chrome, gold, silver, or the like. Cloisonne ware products have been proposed.
Further, Patent Document 2 proposes a decorative object in which a cutout portion is provided on a surface metal plate so that the cloisonne forms a concave surface in the cutout portion or the cloisonne rises from the cutout portion.
Further, Patent Document 3 proposes a cloisonne processing method in which a concavo-convex pattern is formed on a metal base material by pressing or forging, silver plating is applied, and then the cloisonne glaze is filled in the holes or grooves of the concavo-convex pattern.

FIG. 7 is a diagram showing an example of a process of forming a cloisonne pattern on an accessory 1 such as eyeglasses, a necklace, a bracelet, a brooch, an earring, an ankle, a ring, a watch side, or a watch belt according to a conventional example of the present invention. .. In each figure, the main body is shown in cross section.
As shown in FIG. 7A, holes 11a are formed in at least a part of the main body 11 of the accessory 1 made of a metal such as titanium or stainless steel in accordance with the shape of the cloisonne pattern to be formed. ing.
Next, as shown in FIG. 7B, a coating layer 12 such as a plating layer, a coating layer, and a metal vapor deposition layer is formed on the surface of the main body 11.
After that, as shown in FIG. 7C, the hole 11a is filled with the cloisonne-like paint 13 (hereinafter referred to as cloisonne 13).

When the surface of the cloisonne 13 is recessed from the edge 11b of the main body 11 as in the processed cloisonne product of Patent Document 3, the amount of the cloisonne 13 filled in the hole 11a may be reduced, and the cloisonne 13 may be edged. The amount of the treasure 13 may be increased in order to raise the swelling from the portion 11b.
In order to obtain the accessory 1 in which the surface of the cloisonne 13 is flush with the edge 11b of the main body 11 as shown in FIG. 7 (e), the surface of the cloisonne 13 rises from the edge 11b as shown in FIG. 7 (c). After filling the holes 11a as described above, the surface of the cloisonne 13 may be polished with a grinder G or the like as shown in FIG. 7 (d).

Japanese Unexamined Patent Publication No. 2002-46391 Jitsukaisho 57-149199 Japanese Unexamined Patent Publication No. 53-9216

However, when the cloisonne 13 rising from the edge portion 11b is polished with the grinder G as shown in FIG. 7D, there is a problem that the coating layer 12 formed on the surface of the edge portion 11b is also polished.
The cloisonne 13 may be polished as long as the grinder G does not come into contact with the coating layer 12, but such processing is extremely difficult and requires skill, and is unsuitable for mass production and increases the cost. ..
Further, it is conceivable that the step of forming the coating layer 12 (step of FIG. 7 (b)) is performed after the filling / polishing step of cloisonne 13 (step of FIGS. 7 (c) (d)), but cloisonne 13 When the coating layer 12 is formed and exposed to a high temperature, there is a problem that it is easily carbonized and peeled off. For example, when the main body 11 is made of titanium and a plating layer is formed on the surface thereof by an electroplating method or the like, it is necessary to perform heat treatment (baking) to heat the main body 11 to 200 ° C. to 400 ° C. after plating. However, if the main body 11 is heated at such a high temperature, the cloisonne 13 may be carbonized and peeled off. Therefore, in such a case, the coating layer 12 that can be formed on the main body 11 is limited to one that can be formed at a low temperature, and there is a problem that variations in the material and appearance of the main body 11 of the accessory 1 are limited.

The present invention is a method for manufacturing an accessory that can remove such restrictions, expand the range of application of the accessory colored with a colorant such as a cloisonne-style paint, and add further value, and is manufactured by this method. The purpose is to provide jewelry.
