DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of an essential part of a diver watch according to an embodiment of the present invention, and FIG. 2 is a sectional view of an essential part of a watch case according to another embodiment of the present invention.

The diver watch 11, which is an ornamental product, is made of titanium and / or titanium alloy, and a register ring 13 is rotatably attached to the outer periphery of the upper portion of the body 12 via a register ring spring 14. Further, the register ring spring 14 engages with a groove formed on the lower surface of the register ring 13 to regulate the position.

The register ring 13 has a nameplate 15 made of aluminum and / or aluminum alloy on the upper surface.
Is fixed. After the shape is formed, the name plate 15 is fixed to the circumferential groove 13a on the upper surface of the shape-registered register ring 13 by means of press fitting, caulking, welding or the like. In addition, the register ring 13 to which the nameplate 15 is fixed is a portion except the surface of the nameplate 15 which is subjected to anodizing treatment and then has its surface mechanically buffed or chemically and / or chemically pickled. The oxide film has been removed. Since the oxide film (alumite layer) is formed thick on the surface of the nameplate 15, the register ring 13 is formed.
Even if the oxide film on the surface is removed, the oxide film on the nameplate 15 remains. On the oxide film (alumite layer) of the nameplate 15, a printing method,
The numbers 15a, letters, patterns, etc. are formed by means such as a photoresist method.

The above-mentioned register ring 13 had no gap and step with the name plate 15 to which it was attached, and had good appearance quality.

Next, a method of manufacturing the register ring 13 of the diver watch 11 which is a decorative article will be described. The titanium or / and titanium alloy material is used to mold the register ring 13, which is a small component, by a general processing means such as press molding and cutting. On the upper surface of the register ring 13, a circumferential groove 13a to which a name plate 15 described later is fixed is formed. On the other hand, using aluminum or / and aluminum alloy material, the nameplate 15 which is a small part is formed by the same processing means as the register ring 13. Next, the nameplate 15 is fixed to the circumferential groove 13a of the register ring 13 by means of press fitting, crimping, welding or the like. If necessary, the surface of the register ring 13 to which the nameplate 15 is fixed is ground and cut (including cutting with a diamond tool).

Next, the register ring 13 to which the nameplate 15 is fixed is anodized. The conditions of this anodizing treatment are as follows: in a sulfuric acid bath (concentration: about 13% to 17%), temperature: about 0 ° C. to 10 ° C., current: about 1.0 A / dm ² , voltage: about 15 ° C.
V (time about 50 to 70 minutes) and anodized film about 2
0 μm was formed. After that, a mask is formed on the oxide film of the name plate 15 by a printing method or a photoresist method, and dyeing and sealing are performed. Next, the mask is removed by immersing it in an organic solvent or the like. As another anodic oxidation method, in an oxalic acid bath (oxalic acid: 15%, sulfuric acid: 3%, water: balance), the temperature is about 15 ° C to 20 ° C, the current is about 1.5 A / dm ² , and the voltage. Is about 1
If it is performed at 5 V (time of about 40 to 50 minutes), an anodic oxide film of about 20 μm can be formed as described above.

Next, the oxide film on the surface of the register ring 13 having the anodic oxide film formed thereon is removed by mechanical means such as buffing and / or chemical means such as pickling. At this time, since the oxide film formed on the nameplate 15 is thicker than the oxide film formed on the surface of the register ring 13, the nameplate 1
Only the oxide film of No. 5 remains.

According to the above manufacturing method, there is no gap or step with the nameplate 15 attached to the register ring 13, and the number 15a, letters, patterns, etc. are formed in various colors on the surface of the nameplate 15. It has a high quality appearance.

Next, FIG. 2 shows another embodiment of the present invention in which a decorative member 22 having an oxide film is fixed to a recess 21a of a watch case 21 which is a decorative article. The manufacturing method is the same as that of the above-described embodiment, and thus detailed description thereof will be omitted.

Using titanium or / and a titanium alloy material, the watch case 21, which is a small component, is formed by a general processing means. A concave portion 21a to which a decorative member 22 described later is fixed is formed on the surface of the watch case 21.
On the other hand, the decorative member 22, which is a small component, is made of aluminum or / and an aluminum alloy material and is used as the watch case 21.
It is molded by the same processing means as. Next, after fixing the decorative member 22 to the recess 21a of the watch case 21, the surface of the watch case 21 is anodized. Next, the oxide film is removed from the surface of the watch case 21 on which the anodic oxide film has been formed by mechanical means such as buffing or the like and / or chemical means such as pickling. At this time, since the oxide film formed on the decorative member 22 is thicker than the oxide film formed on the surface of the watch case 21, only the oxide film of the decorative member 22 remains.

According to the above manufacturing method, the watch case 21 is used.
There is no gap or step with the decorative member 22 attached to the decorative member 22, and the pattern 23 and the like are formed on the surface of the decorative member 22 in various colors, which gives a high quality appearance.

The conditions of the anodic oxidation treatment are not limited to the conditions described in the above embodiment, but may be appropriately changed depending on the types of materials such as aluminum, aluminum alloy, titanium, titanium alloy, and the thickness of the oxide film. To do. The main reason for removing the oxide film formed on the surface of titanium and / or titanium alloy is that it is difficult to obtain a desired color tone because the color tone of the oxide film changes variously depending on the anodizing conditions. This is because the surface of the ornamental product can be finished as well as removed.

[0019]

As described above, the decorative article made by the present invention has no oxide film on the surface of the small parts made of titanium or / and titanium alloy, and the small parts made of aluminum or / aluminum alloy. Since the surface of the component has an oxide film, it is possible to freely combine colors, patterns, letters, numbers, etc., and it is easy to expand the design variation with high quality.

Further, the method for producing an ornamental product of the present invention is such that after the small item made of titanium or / and titanium alloy and the small item made of aluminum or / aluminum alloy are integrated, an ornamental item is produced. Since the anodizing process and the removal of the oxide film are performed, there are no gaps or steps between the small parts and the combination of colors, patterns, letters and numbers can be freely set. You can easily expand design variations with quality. Further, since the anodic oxidation treatment only needs to be performed once, the manufacturing becomes easy. Furthermore, a gap, a step, or the like can be intentionally provided between the small parts, so that an unprecedented design expression can be achieved.
