DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pierced earring catch for retaining a pin having a decorative portion attached at one end to the back side of an earlobe, and a metal piece for retaining the pin in an elastic material. An object of the present invention is to provide an earring stopper which is easy to handle, has a remarkable action of retaining pins, and can produce a colorful product.

[0002]

2. Description of the Related Art Hitherto, as a fastener for piercing earrings, a fastener made of a noble metal piece commonly called a catch is well known. This catch forms an opening through which a pin is inserted in the center of the noble metal plate, extends at least one pair of side edges in the back direction to form a resilient piece, and further curls the end of the extended portion of the resilient piece. A pinch portion is formed, and the pinch portion is opposed to the pin, and a pin inserted from the pin insertion port is pinched by the pinch portion,
It is designed to hold.

[0003] Such earring fasteners are very excellent in terms of cost and pin retaining function, but have a drawback in decorativeness since they are composed only of functions. Furthermore, since it is usually small due to cost considerations, it is difficult to grasp with fingers, and there is a problem that it is difficult to get into a hole opened for piercing the earlobe. In addition, there is a drawback that the resilient pieces are distorted during repeated use and cannot be removed from the peripheral groove of the pin.

[0004] Further, there is a tendency to avoid catches, which are precious metal products, due to metal allergy, and earring stoppers made of silicone resin, synthetic rubber or other elastic materials have been developed.

[0005] For example, Japanese Utility Model Laid-Open No. 60-6417 discloses a pierced catch made of only an elastic material.
No. 13615 discloses a pierced earring made of a hollow spherical body filled with an elastic material, and Japanese Utility Model Registration No. 3045512 discloses a piercing catch in which a resilient material is housed in a bell-shaped metal cover. Japanese Patent Publication No. 103307 discloses ear ornaments each having a retaining metal fitting in which a cylindrical metal shell is partially fitted at an end of a pin insertion opening made of an elastic material.

[0006]

However, in the pierce catch made of only the elastic material disclosed in Japanese Utility Model Laid-Open Publication No. 60-6417, the force of pinching the pin of the elastic material is weak, and the piercing catch is not easy to handle. Since the material is too soft, there is a drawback that it is difficult to grasp and insert the pin.

The pierced earrings disclosed in Japanese Utility Model Laid-Open Publication No. 61-13615, in which a hollow spherical body is filled with an elastic material, are not only troublesome to manufacture, but also include a pin inserted into the elastic material during use. There has been a drawback that the hole and the pin insertion port provided in the sphere are easily displaced, making it difficult to use.

In a piercing catch in which an elastic material is housed in a bell-shaped metal cover disclosed in Japanese Utility Model Registration No. 3045512, the elastic material easily falls off from the metal cover, and the metal cover becomes large. And the cost is likely to increase.

[0009] In the case of an earring disclosed in Japanese Utility Model Laid-Open Publication No. 1-103307, which has a retaining metal fitting in which a cylindrical metal shell is partially fitted at the pin insertion port end of an elastic material, similarly to the above. There has been a drawback that the elastic material easily falls off from the metal shell portion, and the pin is easily detached because the force of pinching the pin made of the elastic material is weak.

In any case, the above-mentioned Japanese Utility Model Application No. 60-641
In the conventional example other than the piercing catch disclosed in Japanese Patent Publication No. 7-107, no countermeasures against metal allergy or the like were taken into consideration.
