Description

[Detailed description of the invention] [Industrial application field] This invention particularly relates to the improvement of rings made of precious metals such as platinum and gold.

[Prior Art] Conventionally, for example, rings have been formed using precious metals such as platinum and gold, taking into consideration values, decorativeness, affinity with the skin, influence on blood circulation, ease of processing, corrosion resistance, etc. It is used as a material, but one example of classification based on its forming method and finished shape is those that are expanded by flat punching.

[Problems to be solved]

However, in the conventional products mentioned above, the cross-sectional shape of the completed ring is rectangular, and the upper and lower ends are approximately at right angles, so it is easy to get caught when putting it on the finger or taking it out from the finger, and it also feels uncomfortable during use. There was something to remember.

[Purpose of invention]

This idea was made in view of the above points, and its purpose is to fit it on the finger,
To provide a ring that does not get caught when removed from a finger, allows smooth wearing work, does not cause discomfort during use, and is easy to manufacture and process.

[Example of idea]

The details of the present invention will be explained below with reference to an embodiment shown in the drawings.

1 is a precious metal, such as platinum
The ring body is formed by flat punching or the like using as a forming material, and ring-shaped fitting grooves 1b, 1b with a V-shaped cross section are formed approximately in the center of the upper and lower end surfaces 1a, 1a of the ring body 1. has been done. 1c
is a gripping edge that is provided facing the inside and outside with the fitting groove 1b in the center, and becomes thinner toward the tip. Reference numeral 2 denotes a metal wire fixed in the fitting grooves 1b, 1b, and the metal wire 2 is made of, for example, a noble metal different from the material of the ring body 1, such as gold, in order to exhibit decorative properties. Although it is formed to have a circular cross section, it goes without saying that it may be formed of the same material as the ring body 1. Further, the metal wire 2 may have a circular cross section as shown in FIG. 3, or a fan-shaped cross section having an arcuate portion 2a' at least on the outer periphery as shown in FIG.

Also, the width between the opposing gripping edges 1c, 1c.
l ₁ is formed to have a size slightly larger than the diameter φ of the metal wire 2, so that the metal wire 2 can be brazed into the fitting grooves 1b, 1b, or the gripping edges 1c, 1c can be caulked. In some cases, the fitting groove 1
b, 1b is caulked and fixed, and the approximately semicircular arc portion 2a on the outer periphery side fits into the fitting groove 1 of the ring body 1.
b, 1b.

One embodiment of the present invention has the above-mentioned configuration, in which a metal wire 2 having a semicircular cross section or the like and an arcuate portion 2a on the outer periphery is placed in the fitting grooves 1b, 1b formed on the upper and lower end surfaces of the ring body 1. Since the ring R is fixed by brazing or caulking, when the ring R is put on the finger or removed from the finger, the arcuate part 2a of the outer periphery of the metal wire 2, which has a semicircular cross section, comes into contact with the skin and prevents it from sliding. Because it will be done smoothly, ring R
There is no risk of it getting caught on your finger. Further, even during use, due to the presence of the metal wire 2 having the arcuate portion 2a, the upper and lower edges of the flat-beaten ring body 1 do not come into direct contact with the skin, so that no discomfort occurs during use.

In addition, the metal wire 2 is connected to the upper and lower end surfaces 1 of the ring body 1.
The ring body 1 is made of platinum, which is a precious metal, and the metal wire 2 is made of gold, which is a precious metal. or conversely, the ring body 1 is made of gold and the metal wire 2
When the ring body 1 and the metal wire 2 are made of platinum, the colors of the metals used to form the ring body 1 and the metal wire 2 are different, so that the ring body 1 looks good and its decorative value increases. Furthermore, if jewelry is attached to the ring body 1, its decorative value will further increase.

In the above embodiment, the ring body 1 and the metal wire 2 are made of precious metals such as platinum and gold, but the ring body 1 and the metal wire 2 are not limited to these precious metals. Needless to say, it's a good thing.

In addition, in the above embodiment, there are fitting grooves 1 on both the upper and lower end surfaces.
b, 1b and has a circular arc portion 2a.
The structure is such that they are fixed by brazing or caulking, respectively, but the fixed location may be on one end surface. Further, in the above embodiment, one metal wire 2 is fixed to the ring body 1, but a plurality of fitting grooves 1b are provided, and a plurality of metal wires 2 are fixed to each of the fitting grooves 1b. It's okay.

[Effect of idea]

As described above, in the present invention, ring-shaped fitting grooves are formed on the upper and lower end surfaces of a flat metal ring body, and a metal wire having, for example, a semicircular cross section and having an arcuate portion on the outer periphery is inserted into the fitting groove. Since it is fixed in the groove and the circular arc part protrudes from the substantially right-angled end surface of the ring body, there is no catch when putting it on or taking it out from the finger, allowing you to smoothly put on and take off the ring, and also eliminate any discomfort during use. I never remember.
