[Problems to be solved by the invention]

 However, in the conventional design parts, first, hemispherical molds 11a and 11b are formed into round spheres 11 by brazing or heat welding, and holes 14 and 14 are pierced in the spheres. And the non-crosslinked silicone rubber is poured into the cavity 13 in the round sphere 11, and is heated and crosslinked while maintaining this state, and the silicone elastomer 15 is filled in the round sphere 11, and this silicone elastomer is filled. A small hole 17 must be made in the hole 15 with a needle-like object, and the chain 12 must be inserted into this hole 17. The smaller the design parts, the more complicated the manufacturing and the higher the manufacturing cost. There was such a problem. The purpose of the present invention is to provide a design part for a decorative chain having various shapes (designs), which is easy to manufacture and low in manufacturing cost.

Embodiment

 FIG. 1 shows an embodiment of a design part for a decorative chain according to the present invention. The design part 1 is designed to be locked in the middle of a decorative chain hanging on a neck. A hollow elastic material made of an elastic material tube 3 is placed in a shell 1c made of a noble metal pipe 2 made of gold, silver, platinum, or the like, provided at two locations where holes 1a slightly larger than the diameter are opposed to each other. 1d. The elastic tube 3 is made of, for example, silicone rubber, natural rubber, soft plastic, or the like. The shape of the noble metal shell 1c may be a sphere as shown in FIG. 1 or a mirror ball (not shown).

As shown in FIG. 2, a decorative part 1 for a decorative chain according to the present invention is provided in a pipe 2 made of a noble metal such as gold, silver, or platinum. The material 4 into which the material tube 3 is inserted is intermittently rotated as shown by an arrow A as shown in FIG. the direction of movement of the plurality of concave 5 ₁ so as to approach the rear side to the shape of sequential half殼体1c 'follow to go to the front _side, 5 2, _{5 3,} 5 ₄ pair of molds 5, 5 to form a By intermittently pressing, a design part 1 having a hollow elastic material 1d is connected and formed in a shell 1c, and the connected design part 1 is cut from a connection part 1e with scissors or the like. Formed with a tool It is something. The material 4 is intermittently moved in the direction along the axis, as indicated by the arrow B, and the moving pitch is equivalent to the length of the diameter of one design part 1 to be formed. .

FIG. 4 is a diagram showing an example of a decorative chain made by using the design part of the present invention. The holes 1a, 1a formed in the shell 1c of the design part 1 as shown in FIG. Holes 1b, 1b are made in the hollow elastic material 1d with a needle-like object or the like, and the bent portion 6 'of the decorative chain 6 is inserted through the holes 1b, 1b and the holes 1a, 1a. An ornament 7 is attached to the end of the bent portion 6 ', and anchors 8, 8' are attached to both ends of the decorative chain 6 to form a decorative chain. When the design part 1 attached to the decorative chain 6 is moved as shown by arrows a and b, the design part 1 is moved to the moved position by the elasticity of the hollow elastic material 1d in the design part 1. Is held.

[0012]

[Effect of the invention]

 This design uses precious metal pipes for the shell of the design parts, so there is no need to provide holes for penetrating the decorative chain on both sides of the shell as in the conventional technology, making manufacturing simple and manufacturing cost-effective. Inexpensive, and it is easy to provide design parts of various shapes (designs).

Further, in the present invention, since a tube is used for the elastic material, when drilling a hole for inserting the decorative chain into the elastic material tube, wires and the like are formed from two opposing holes of the shell. By the means described above, a hole can be easily formed.
