Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a member for jewelry used for jewelry such as necklaces, earrings and broaches.

[0002]

2. Description of the Related Art Precious metals have been used as various accessories for jewelry because of their high quality. For example, a member formed into a small block is connected to form a necklace, or a stopper to form an earring or brooch. It is well known. Among them, there is a conventional accessory that is formed into a small block body using a wire material because it is light in weight for its bulk. As an accessory using such a wire rod, the main part of the accessory described in Japanese Patent Application Laid-Open No. 2-57202 is composed of a wire formed by twisting a plurality of wire rods, and the wire is formed in a spiral shape having expandability and contractibility. There is a wire type accessory.

[0003]

By the way, the inventors of the present invention have made various trials in order to obtain a member for an accessory used for decoration such as a necklace or an earring by using a fine wire of precious metal. As a result, in the accessory member formed by simply forming the fine wire of the precious metal into a spiral shape as described above,
Just because the shape is different from other things such as spheres, which are traditional, the value of the thing ends up only by the value of using precious metal as a material, and there is no point that stands out especially from other things, the inventor They were not satisfied. However, even with such a spiral body, in a spiral body in which adjacent thin wires are in close contact with each other, it has been found that the reflected light emitted from each of the thin wires intermingles to produce a beautiful shine. And as a result of further study, if the thin wire is a twisted wire, the brightness of the thin wire itself becomes dull,
When the spiral body is made into a ring and used as a member for jewelry, a gap is formed on the surface of the spiral body, and the overall brightness becomes dull,
Since the spiral body is formed of fine wires of noble metal, it was found that the shape of the spiral body collapsed due to a slight external force, and the present invention was reached by solving these problems.

That is, an object of the present invention is to provide a member for jewelry which is made of a fine wire made of a precious metal and which has a beautiful shine and is beautiful and which does not easily lose its shape due to an external force.

[0005]

In order to achieve the above object, the member for accessory of the present invention comprises a single wire of a precious metal thin wire, and a reinforcing member for preventing the shape of the spiral member from collapsing in a spiral member in which adjacent single wires are in close contact with each other. Is built in. Furthermore, in a spiral body composed of a single wire of a precious metal thin wire, adjacent single wires are in a spiral shape having a polygonal cross-section in close contact, and each ridge line formed by the corners of the polygonal cross-section has a spiral shape, It is configured to include a reinforcing body that prevents the spiral body from losing its shape.

The noble metal in the single wire of the noble metal according to the present invention is limited to a material having a rich jewelery value,
A noble metal containing gold, silver, platinum, palladium, rhodium or the like as a main component or an alloy thereof is preferable. Single wire does not include fine wires twisted together, and the wire diameter is about 0.1 m.
The range from m to 0.5 mm is preferable.

The reinforcing body is built in the spiral body in order to prevent the spiral body from losing its shape due to an external force, and its shape is not particularly limited. For example, a spiral or net-like cylindrical body,
The shape may be a pipe or a rod, but a hollow body such as a tubular body or a pipe is preferable in order to reduce the weight of the accessory member. Further, in the case of a spiral shape or a net-like cylindrical body as shown in FIG. 3, not only strength is obtained but also appropriate flexibility is provided, so that it is suitable as a member for accessories such as a necklace. Further, the outer shape may be freely set without being restricted by the shape of the spiral body. For example, the shape of the spiral body may be a quadrangular cross section, and the shape of the reinforcing body may be a circular cross section. If the reinforcement has a similar shape with a slightly smaller outer diameter than the shape of the spiral body, for example,
The reinforcing body can be easily incorporated in the spiral body by spirally winding the reinforcing body around the core material and further winding the spiral body on the surface of the core body.

Regarding the material of the reinforcing body, noble metal, base metal,
Any material such as a non-metal may be used, and is not particularly limited, but a noble metal, which is the same as the spiral body, is preferable.

To incorporate the reinforcement into the spiral, for example,
First, a reinforcing body as described above is formed, and then a spiral body is formed on the reinforcing body, whereby the reinforcing body is embedded in the spiral body, or the reinforcing body and the spiral body are separately formed, and the reinforcing body is formed in the spiral body. There is a method of inserting the reinforcing body into the spiral body by inserting it into, and any method may be selected.

The outer spiral body and the inner reinforcement body can be integrated by fixing them, but at this time, if the inner surface of the spiral body and the surface of the reinforcement body are fixed, the flexibility of the spiral body is impaired. It is preferable to fix the end of the reinforcing body and the end of the spiral body. When a hollow body such as a pipe is used as the reinforcing body, it is preferable to use a spiral body having an outer diameter smaller than the inner diameter. There are no particular restrictions on the method of fixing, and there are methods such as brazing and adhesives, but a method of brazing with a precious metal brazing material is preferable from the viewpoint of the strength of the end face.

[0011]

Since the accessory member is made of a noble metal single wire and has a spiral shape as described above, the reflected light emitted from each of the single wires intermingles gives a beautiful shine.

Since the reinforcing body is built inside the spiral body,
It is difficult for the spiral to lose its shape due to external force. Further, since the reinforcing body is fixed to the end portion of the spiral body, there is a degree of freedom in movement such as twisting in the central portion of the spiral body.
