[Embodiment of device]

 Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a sectional view showing a first embodiment of the present invention. As shown in FIG. 1, the necklace component of the present invention comprises a spherical body 1. The spherical body 1 has a cavity 2 inside and two communication ports 3 communicating the cavity 2 with the outside. The spherical body 1 is formed by welding metal members 1a and 1b having two different colors. One or both of these metal members 1a and 1b may be alloy members.

When making this necklace component, the side portions of two metal tapes made of metal members having two different colors are welded or welded by a welding agent, and the welded metal tape is piped by a molding machine. After forming into a shape, a continuous body of a plurality of spherical bodies is formed and then cut. The ratio of the two metal members 1a and 1b having different colors in the spherical body 1 is preferably a value within the range of 3: 7 to 7: 3. As the metal members 1a and 1b in the spherical body 1, for example, gold, platinum, silver or the like is used. Further, the alloy member in the spherical body 1 is made of at least two selected from gold, platinum, silver, copper and palladium.

As shown in FIG. 2, a necklace component according to another embodiment of the present invention comprises a polyhedron 4 having a plurality of flat surfaces on its outer surface. The polyhedron 4 has a cavity 5 inside and two communication ports 6 that communicate the cavity 5 with the outside. The polyhedron 4 is formed by welding metal members (or alloy members) 4a and 4b having two different colors.

As shown in FIG. 3, the necklace of the present invention comprises a plurality of spherical bodies 1 and a connecting linear member 7 through which the cavities 2 and the communication ports 3 of these spherical bodies 1 are inserted. ing.

The connecting linear member 7 is made of, for example, gold or platinum. Locking tools (not shown) for locking the connecting linear members 7 are attached to both ends thereof. The necklace of the present invention may be configured by the polyhedron 4 shown in FIG. 2 instead of the spherical body 1.

Further, as shown in FIG. 4, a necklace as another embodiment of the present invention has a cavity 5 inside and two communication ports 6 communicating the cavity 5 and the outside. It comprises a plurality of the polyhedrons 4 and a plurality of connecting members 8 for connecting the polyhedrons 4 adjacent to each other. The connecting member 8 is formed on both ends of the connecting rod 8a and the connecting rod 8a having both ends inserted into the cavities 5 of the two adjacent polyhedrons 4 through the communication ports 4, and And a locking projection 8b larger than the mouth 4. The connecting member 8 is made of a metal material such as gold or platinum. The necklace of the present invention may be constructed by the spherical body 1 shown in FIG. 1 instead of the polyhedron 4.

Next, a method for manufacturing the necklace shown in FIG. 4 will be described. First, as shown in FIG. 5, a plurality of connecting members 8 made of a metal material such as gold or platinum and having connecting rods 8a and locking projections 8b at both ends thereof are adjacent to each other so as to be substantially linear. The connecting member connecting body A in which a part of the locking projection 8b is connected is produced.

Next, as shown in FIG. 6, one spherical surface having a cavity 10 inside each of the two connecting projections 8b of the connecting member and the connecting member A is made of a metal material such as gold or platinum. A spherical body connected body B is formed in which the body 9 is covered and a part of the adjacent spherical bodies 9 is connected and the internal cavity 10 is connected.

Next, as shown in FIG. 7, the surface portion of the spherical body 9 of the spherical body coupling body B is ground and polished to form a polyhedral body coupling body C in which the polyhedral bodies 4 are coupled. At this time, the spherical body connecting body B can be held by a chuck and can be intermittently rotated by a predetermined angle, and can also be intermittently fed in the direction of the diamond bite at intervals of one spherical body 9. In this state, while holding the spherical body connecting body B with the vise arranged under the diamond cutting tool, the diamond cutting tool is rotated and moved up and down to scrape and polish the surface of the spherical body 9. The surface portion of the spherical body 9 can be rapidly and accurately ground and polished to form the polyhedron 4.

Next, as shown in FIG. 4, after cutting the connecting portion of the polyhedral connecting body C with a cutter, a tensile force is applied to the connecting member connecting body A by a finger or the like so that the connecting member connecting body A A necklace can be manufactured by separating the connecting members 8 one by one.
