For example, it is well known to connect members configured in small blocks to form a necklace. It is also known that when making small blocks like this, if they are hollow, they are lightweight and inexpensive, but in order to obtain a beautiful surface pattern that is rich in aesthetics, complex forming processes such as cutting are required. I need. In order to solve the above-mentioned problems, the present inventors considered using a helical body of precious metal wire as a member for jewelry, but found that there were problems as described below.

0003

[Problems to be Solved by the Invention] That is, if the noble metal wire is thin, it lacks strength and is likely to lose its shape due to external pressure. Such strength problems occur only in precious metal thin wires, and not in base metal thin wires such as stainless steel wires. Precious metal thin wires have such problems, but
It has the advantage of being lightweight, inexpensive, and provides a member for accessories with a beautiful spiral pattern.

[0004] In view of the above, one of the objects of the present invention is to provide a member for jewelry made of noble metal that is lightweight, inexpensive, strong, and aesthetically pleasing. Further, one of the objects of the present invention is to provide a method of manufacturing a member for an accessory that is excellent in mass production and has a rich aesthetic sense.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the first accessory member of the present invention comprises a spiral body made of a thin single wire of precious metal, and a brazing material made by bonding adjacent single wire portions from the inside of the spiral body. It is characterized by being formed into a pipe shape.

A second accessory member of the present invention is formed into a pipe shape by a spiral body having a polygonal cross section made of a thin single wire of a precious metal, and a brazing material that connects adjacent single wire portions from the inside of the spiral body. It is characterized in that the corners of the single wire portions forming each ridgeline of the cross-sectional polygon and the corners of adjacent single wire portions are all sequentially shifted in a direction perpendicular to the center line.

[0007] In the first method of manufacturing an accessory member of the present invention, a thin single wire of precious metal is spirally wound around a rod-shaped core material and annealed, the rod-shaped core material is extracted, and then adjacent single wire portions are separated. It is characterized by forming a pipe shape by joining the spiral body with a brazing material from the inside.

[0008] The second method of manufacturing a member for jewelry according to the present invention is to spirally wind a thin single wire of precious metal around a rod-shaped core material having a polygonal cross-section, extract the rod-shaped core material, and then annealing it. It is characterized in that adjacent single wire sections are joined together from the inside of the spiral body using a brazing material to form a pipe shape.

[0009]

[Function] According to the first accessory member of the present invention constructed as described above, it is lightweight and inexpensive because it uses a thin single wire of precious metal, and because it is a spiral, a beautiful spiral pattern can be obtained.
Adjacent single wire sections are bonded together using brazing material to form a pipe shape, which provides strength, and since the brazing material is bonded from the inside of the spiral body, the brazing material is not visible from the outside, making it a beautiful piece for jewelry. No adverse effects.

According to the second accessory member of the present invention, in addition to the advantages of the first accessory member, it has rich undulations of mountains and valleys,
A beautiful three-dimensional spiral pattern with a subtle shine can be obtained.

According to the first method for manufacturing accessories members of the present invention, the rod-shaped core material is extracted after the solid wire is annealed, so that the gap between the solid wire portions when wound is such that the rod-shaped core material is extracted. Therefore, the brazing work of the single wire parts can be performed efficiently. Note that if the annealing treatment is performed while compressing the spiral body in the longitudinal direction, it is not necessary to tightly wind the spiral body around the rod-shaped core material in advance, that is, to wind the adjacent single wire portions of the spiral body in a close state.

According to the second method of manufacturing a pipe-shaped accessory member of the present invention, since the solid wire is wound, the rod-shaped core material is extracted, and then annealed, the spiral body is bent in the direction of winding due to the action of springback. Go back a little in the opposite direction to the corner of the single line part that forms each ridgeline of the cross-sectional polygon,
The corners of adjacent single wire portions can all be sequentially shifted in a direction perpendicular to the center line.

[0013]

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing a first embodiment of the accessory member of the present invention. This jewelry member is composed of a thin single wire 1 made of precious metal, a spiral body 2 with a rectangular cross section in which adjacent single wire portions are in close contact with each other, and a brazing filler metal 3 in which all adjacent single wire portions are joined from the inside of the spiral body 2. It is formed into a pipe shape, and the corner portions 4 of the single wire portions forming the respective ridge lines of the rectangular cross section and the corner portions 4 of the adjacent single wire portions are all sequentially shifted in a direction perpendicular to the center line.

[0014] The accessory member constructed in this manner is lightweight and inexpensive because it uses a thin single wire made of precious metal. In addition, because it is a precious metal and the corners of the single wire parts forming each ridgeline of the rectangular cross section and the corners of the adjacent single wire parts are all sequentially shifted in the direction perpendicular to the center line, it is a spiral shape, so A beautiful three-dimensional spiral pattern with a rich subtle shine can be obtained. Furthermore, since the adjacent single wire portions of the spiral body are bonded together using a brazing material to form a pipe shape, strength is obtained and excellent deformation resistance is achieved. moreover,
Since the single wire parts that are adjacent to each other in close contact with each other from the inside are connected with the brazing material, the brazing material is not visible from the outside and does not adversely affect the beauty of the accessory member.

[0015] This accessory member is manufactured with a diameter of 0.2 m.
Green gold colored 18K gold alloy (Au7) with m and weak elasticity.
After a solid wire of 5% Ag and 25% Ag was tightly wound in a spiral around a rod-shaped core material with a square cross section (3 mm on each side), the rod-shaped core material was extracted. Subsequently, the spiral body is compressed in the longitudinal direction with a set screw, and heat-treated at a temperature of 650 degrees for 15 minutes in an argon gas atmosphere furnace. Then, a gold brazing material (Fusion Paste No. 2460Y) is applied to the inside of the spiral body, and heat-treated at a temperature of 750 degrees for 5 minutes in an argon gas atmosphere furnace.

According to this manufacturing method, after the single wire is spirally wound around the rod-shaped core material, the rod-shaped core material is extracted.
The helical body extracted from the rod-shaped core material returns a little in the opposite direction to the direction in which it was wound due to the action of springback, and as shown in Figures 1 and 2, a gap is created between adjacent single wire parts. The direction in which the corner 4 of is perpendicular to the center line (A) (
B) shifts in the order of ■→■→■→■. In addition, since the spiral body is compressed in the longitudinal direction and heat treated, adjacent single wire portions of the spiral body can be held in close contact with each other in a pipe shape, and the process of applying the brazing material to the spiral body can be performed efficiently.

[0017] When the single wire of precious metal is somewhat thick, brazing has good deformation resistance even if it fills the gap between the adjacent single wire portions of the spiral as shown in Fig. 3, but when the single wire of precious metal is too thin, It is preferable to make the brazing material layer thick as shown in FIG.

It is formed into a shape.

[0020] Since the accessory member constructed in this manner uses a thin single wire made of precious metal, it is lightweight and inexpensive. Also, because it is made of a precious metal spiral, a beautiful spiral pattern can be obtained. Furthermore, since the adjacent single wire portions of the spiral are joined together using a brazing material to form a pipe shape, strength is obtained.
Excellent deformation resistance. Furthermore, since the single wire portions are bonded to each other in close contact with each other from the inside using the brazing material, the brazing material is not visible from the outside and does not adversely affect the beauty of the accessory member.
