Description

The present invention relates to a connecting structure for an accessory in which a decorative body that moves along a chain member is attached to a chain member such as a necklace.

As a conventional accessory such as this kind of necklace, a so-called rosary, that is, a structure in which a string or a spherical decorative body is connected through a string-like member or a decorative body is connected with a chain is known. .

In some cases, a string or a chain is passed through a decorative body having a through-hole, and the length of the looped chain or the like can be adjusted by moving the decorative body.
Among them, the one disclosed in JP 2000-166623 A (see Patent Document 1) is embedded in the through hole and embedded in the through hole, and the inner diameter of the opening at the end is wider than the inner diameter of the central part. An elastic body made of silicon rubber, and a chain member that has an outer diameter that matches the inner diameter of the central portion of the elastic body, and is inserted into the elastic body. It is possible to move along. The elastic body made of silicon rubber includes a step of filling clay-like silicon into the through hole of the decorative body, a step of passing the shaft through the silicon, and a rubber-like cylinder by heating the silicon together with the shaft. A step of removing the shaft body from the cylindrical body, a step of cutting the opening of the cylindrical body to increase the inner diameter, and a step of inserting a chain member into the cylindrical body. Embedded.
The registered utility model No. 3063890 (refer to Patent Document 2) has an adjuster chain attached to one end of a decorative chain and a design part made of a round ball, a mirror ball, a pipe or the like at the other end of the decorative chain. And insert an elastic body such as silicon rubber into the design part, and further provide a through hole slightly smaller than the diameter of the adjuster chain in the elastic body such as silicon rubber. The adjuster is inserted through the chain.
JP 2000-166623 A Registered Utility Model No. 3063890

However, both of Japanese Patent Laid-Open No. 2000-166623 (see Patent Document 1) and registered utility model No. 3063890 (see Patent Document 2) are elastic bodies such as silicon rubber in a decorative body (design part). , Heat-curing, and post-processing are required, and the production takes a lot of labor, skill is required, and it has been a cause of cost increase.

In addition, the elastic body may protrude outside the decorative body during use, or the elastic body may be visible from the outside, which often degrades the quality of appearance and impairs the sense of quality of jewelry. there were.

The present invention has been made in view of the above-described problems of the prior art, and provides a connecting structure for an accessory that is excellent in appearance quality, smooth in operation, does not impair the sense of quality, is easy to manufacture, and can reduce costs. It is something to try.

The connecting structure for an accessory according to the present invention includes a decorative body having a cylindrical through-hole, a ring-shaped elastic body fitted along the inner diameter of the through-hole , and a ring-shaped elastic body sandwiched from both sides. A cylindrical elastic body holder that prevents the ring-shaped elastic body from slipping out , the inner diameter of the ring-shaped elastic body is smaller than the inner diameter of the elastic body holder, and the outer diameter matches the inner diameter of the ring-shaped elastic body The ring-shaped elastic body is made of silicon rubber, and the decorative body can be moved along the chain-shaped member by inserting the ring- shaped member through the ring-shaped elastic body. It also features that.

In the connecting structure for a jewelry according to the present invention, the ring-shaped elastic body is previously formed into a ring shape and fitted into the cylindrical through-hole of the decorative body, or the solid elastic body is used as a decorative body. after it of snaps does the cylindrical through-hole, of the assumed to be boring into a ring shape, both are possible.

According to the present invention, since the rigid elastic body holder is arranged on the end surface of the cylindrical through hole of the elastic body, the chain member can be easily inserted, and the opening of the elastic body can be moved when the decorative body is moved. Even if an unreasonable force is applied due to the chain member being caught in the vicinity of the part, it is durable and can be moved smoothly.

Further, since the elastic body is held by the elastic body holder inside the decorative body, the elastic body can be adhered and fixed to the decorative body without using an adhesive or the like. For this reason, the outer side of the decorative body is not stained with an adhesive or the like, and the appearance quality is excellent.
