Abstract

PROBLEM TO BE SOLVED: To constitute a decoration having a pattern as a conspicuous presence by engraving a pattern on an outward surface, cutting the surface into a polyhedron, and bringing the pattern into relief therein. SOLUTION: A character 5 or pattern is engraved on the surface of a rectangular plate in a fixed depth or more to form a groove by the character 5 or pattern. The rectangular plate is curved so that the character 5 or pattern is situated on an outward surface 2, and both the end parts thereof are mutually brazed to form a ring body as a ring 1. The character 5 or pattern is arranged within a cut polyhedral surface 3 cut into a polyhedron with a diamond bite. Since this cut surface 3 is mirror finished, the brightness can be changed according to the angle to see as a mirror ball so that the character 5 or pattern can be brought into relief on the outer surface of the ring 1, and the presence of the character or pattern can be made conspicuous to provide a large decorative effect. Since the polyhedral cut surface is formed after the character 5 or pattern is engraved, the fear of damaging the mirror finished surface can be eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a ring as an accessory and a ring.

[0002]

2. Description of the Related Art A decorative ring is important for a ring, but an engagement ring and other memorable rings are often relatively simple designs such as Komaru and flat.

By the way, when engraving a character on a ring, usually it is often put on the back side. The reason is that when engraved letters, these letters are composed of so-called linear grooves, and unless they are specially colored, they have the same color as the precious metal of the ring, which is a bullion, and are inconspicuous, Because there is no.

[0004]

However, in the case of a ring with a memorial, it is important to apply the memorial character or graphic on the outward surface of the ring and use it as a decoration to make the memorial character of the ring stand out. Therefore, it is desirable to increase the value as a unique thing and there are many desired directions, but coloring characters and figures with paint etc. gives a cheap impression and has noble metal The purity is impaired, which is not preferable.

However, drawing characters and figures by embedding other precious metals or shells by techniques such as inlaying is extremely time-consuming. It will rise in proportion.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned disadvantages of the prior art, and when characters and figures are applied to the outward surface of a ring, these characters and figures become conspicuous, which is suitable for constructing a decoration. A method of manufacturing a ring and a ring.

[0007]

According to the present invention, in order to achieve the above object, as a method of manufacturing a ring, a character or a figure is engraved on an outward surface at a predetermined depth or more, and the outward surface is diamond-shaped. It is cut into a polyhedron with a cutting tool, and letters or figures emerge in the cut polyhedron. The body is bent into a ring with the character side facing outward, and the outward surface is cut into a polyhedron with a diamond tool, so that characters or figures emerge in the cut polyhedron. Is 180 °
The gist of the invention is that the polyhedron is a 60-faced cut face.

In addition, as the ring, a polyhedron cut surface by a diamond is provided on the outward surface so as to form vertical stripes in the vertical width direction of the ring, and characters or figures are provided in the polyhedron cut surface in the circumferential direction of the ring. The gist is that they are arranged side by side and that the polyhedron cut surface is a 60-hedron.

According to the first and fourth aspects of the present invention, a character or a figure is cut into a polyhedron by a diamond, and the character or a figure is arranged in the cut polyhedron. If the cut surface is a mirror-finished surface, the brightness changes depending on the viewing angle like a mirror ball, allowing characters or figures to appear on the outer surface of the ring. The effect is obtained.

When a polygonal cut surface is first formed by mirror finishing and a character or figure is engraved thereon, the polygonal cut surface may be erroneously damaged and the mirror finish may be lost. Since the present invention engraves a character or a figure first and forms a polyhedron cut surface thereon, there is no such concern. In addition, the grooves constituting the characters and figures are slightly shaved when the polyhedron cut surface is formed, but are pre-engraved at a certain depth or more,
Almost no problem.

According to the second aspect of the present invention, in addition to the above-described functions, characters and figures are applied not in the state of a ring but in the state of a rectangular plate, so that work can be easily performed in a stable state.

According to the third and fifth aspects of the present invention, since the polyhedron is a 60-faced cut face, the mirror surface of the vertical stripes in the vertical direction is fine.
The contrast between the character and the figure is not unreasonable, and the smoothness of the arc as the outer surface of the ring is not lost because the plane is not a continuation of a plane having a large vertical stripe width.

[0013]

Embodiments of the present invention will be described below in detail. FIG. 1 is an explanatory view showing one embodiment of a ring of the present invention, in which 2 indicates an outward surface of the ring 1.

According to the present invention, the outwardly facing surface 2 is provided with a unit cut surface 3 by mirror finishing, which is cut with a 180 ° diamond tool.
a is continuous so as to form vertical stripes in the vertical width direction of the ring body.
A polyhedron cut surface 3 of a face was provided. In the figure, reference numeral 4 denotes a chamfered portion of the upper and lower edges of the ring.

In the polyhedron cut plane 3, a 0.
Characters 5 or figures engraved at a depth of about 2 mm were arranged side by side in the circumferential direction of the ring. In the illustrated example, the character 5 is a cursive alphabet and has continuity.

Next, a method for manufacturing a ring according to the present invention will be described. The engraving of the character 5 may be performed on the outer surface after forming a ring with a noble metal such as gold, platinum, silver or the like, but as shown in FIG. And engraved on the surface of the flat plate 6 at a depth of about 0.3 mm.

As shown in FIG. 5, the character 5 has a bottom width of about 0.2 mm and an opening formed by a 120 ° groove.

Next, as shown in FIG. 3, the rectangular plate 6 is bent so that the character 5 comes to the outward surface 2, and the ends are brazed to form a ring as the ring 1.

Then, as shown in FIG. 4, cutting is performed with a 60-sided face using a 180 ° diamond tool. By this cutting, the outward surface 2 of the ring 1 is shaved by about 0.1 mm, and the rest becomes about 0.2 mm in depth. However, the required depth can be sufficiently secured.

Although the cutting of the 60-hedron is not shown, the ring 1 is brought into contact with the diamond while slightly turning it, and the unit cut surfaces 3a are sequentially connected.
At the same time, the chamfered portions 4 on the upper and lower edges of the ring are formed for each unit cut surface 3a with the same mirror finish.

In the above embodiment, the polyhedron cut surface 3 is a 60-sided one, but it is not always limited to this number and can be changed. The same applies to the frequency of the byte, and the character 5 can be replaced with Japanese characters or figures.

[0022]

As described above, the method of manufacturing a ring and the ring according to the present invention can be applied to an outer surface of a ring such as a mirror ball whose brightness changes depending on the viewing angle when characters or figures are formed on the outward surface of the ring. The contrast between the character and the graphic provided on the outer surface thereof makes the character or graphic prominent, and is suitable for forming a decoration.
