Description

  The present invention relates to a catch for jewelry that can be moved while giving resistance that makes it difficult to move the chain through the chain, or that can be pulled out through a pin such as a pierspin or a tie pin so that the chain is not easily pulled out.

(1) Holding a through wire in the center of the noble metal pipe, injecting and solidifying a liquid silicon resin into the noble metal pipe, forming the noble metal pipe into a form in which a plurality of spheres are connected through a plurality of press processes. Then, a design part (catch for jewelry) having an elastic body formed by extracting a through-line to form a decorative chain insertion hole (through hole) and separating a spherical body is known. (For example, Patent Document 1)
(2) A rubber pipe made of silicon rubber or natural rubber for a noble metal pipe is provided, the noble metal pipe is formed in a form in which a plurality of spheres are connected through a plurality of press processes, and an elastic body formed by separating the spheres is included therein. Design parts (catch for jewelry) are known. (For example, Patent Document 2)
(3) A curved sandwiching plate is mounted on the base so that the pin insertion hole (through hole) is sandwiched in a substantially semi-spherical elastic body of a silicon rubber member having a pin insertion hole penetrating in the center. There is known a pin catch provided with a metal catch provided by integral molding and having a ring portion formed by extending a part of a base and projecting out of the elastic body. (For example, Patent Document 3 (FIG. 10))
JP 2000-312607 A JP 2000-245516 A Japanese Patent Laying-Open No. 2005-204991 (FIG. 10)

(1) The design catches of Patent Document 1 and Patent Document 2 of the prior art are only elastic body flesh that holds the inserted chain elastically so as not to move and elastically hold the chain. If the chain to be inserted and moved is moved about 15 to 200 times over a distance of 15 cm, the elastic pinching force of the elastic body is almost lost (becomes stupid, sags, loses elastic force, becomes soft The through-holes are widened, the through-holes are shaved and widened, the oils and fats are attached to the hand, and the sliding is improved by rubbing, or a combination of these)) The function of holding in place and holding the pins so as not to be pulled out has the disadvantage that the number of times of use occurs between 150 and 200 times.
Further, since the chain passed through the through hole is clamped by the elastic clamping force of only the elastic body, the allowable range of the diameter of the chain that can be passed while maintaining the elastic holding force is narrow. For example, the work of expanding the through-hole diameter according to the chain diameter must be performed.
Specifically, in the case of a catch for an accessory only having an elastic body diameter of 4 mm and a through hole of 0.6 mm, a chain having a chain diameter of about 0.9 mm to 1.2 mm is an allowable range, and the diameter of the elastic body is In the case of the catch for jewelry of the present invention having 6 mm and a through hole of 1.0 mm, a chain diameter of about 1.5 mm to 2.0 mm is an allowable range.
(2) Pin Catch of Patent Document 3 [a] The pin catch of Patent Document 3 of the prior art elastically holds a pin or chain passed by a metal plate surface integrated with an elastic body meat. The chain abutment surface, which is the clamping part of the metal plate material, becomes stupid, sags, loses elastic force, becomes soft, the through-holes expand, the through-holes cut and expand, etc. The elastic body flesh in the curved pinching plate portion that is not elastically applied to the curved pinching plate portion is not directly in contact with the chain by the curved pinching plate and is locally depressed. Since the deformation is dispersed and protected to be a small deformation so as not to be deformed, a configuration in which the elastic force does not decrease is realized.
In other words, the elastic catching force is not reduced or ridiculous by integrating the metal catch and the elastic body (in the experiment, a sufficient elastic holding force was maintained even if the chain was moved a distance of 15 cm 2000 times). To do.
However, the pin catch that is similar to the pin catch of Patent Document 3 and does not have an annulus is viewed from the viewer and looks like a gold pin catch. In order to give a feeling, a metal catch made of gold is integrated into an elastic body made of transparent silicon rubber. In order to reduce the cost due to expensive gold as much as possible, The thickness is as thin as 0.05 mm.
When this ring base is formed by extending this 0.05 mm thick base and projecting it out of the elastic body, it becomes a 0.05 mm thick ring. When the members are connected, they are easily cut by a weak tensile load and cannot be used unless the strength required for the ring portion is obtained.
When forming a sufficiently strong ring part with a gold member, it is necessary to have a thickness of at least 0.3 mm in diameter. When providing a ring part on a metal catch of a gold member, the thickness of the base and the curved part Has to be 0.3 mm, and the amount of gold used is 6 times (0.3 mm / 0.05 mm), resulting in a significant cost increase.
In addition, the thickness of the metal catch, which is a metal member of 0.05 mm, is almost the limit, and it is difficult to reduce the metal catch, which is a metal member that accounts for 70% or more of the cost. There is a problem that the cost reduction is difficult to achieve.
[B] In addition, the pin catch of Patent Document 3 of the prior art is a method of injecting heat-melted silicon rubber into a mold set with a metal catch and integrally molding it. In this case, a support pin fixed in a mold slightly thicker than the earring pin passed through the through hole is passed through a pin through hole formed in the center of the base of the metal catch.
That is, the pin hole of the metal catch has a drawback that it cannot pass a pin or chain thicker than a predetermined earring pin.

  The present invention has been made in view of the drawbacks of the prior art as described above, and the function of the elastic clamping force is not lost even when the pin or the chain passed through the through hole is moved many times. At the same time, the object is to provide a catch for jewelry that achieves cost reduction.
