Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an earring called a pierced earring.

(Prior Art) Earrings called pierced earrings are composed of a decoration fixed to the tip of a pin, such as a gold wire or a gold-plated wire, and a stopper for inserting and fixing the pin.

Previously, the above-mentioned fasteners had a pin insertion hole formed in the center of the leaf spring, and both ends of the leaf spring were curved circularly to form clamping pieces that abutted each other at positions opposite to the pin insertion hole. The penetrating pin is clamped and stopped by a pair of circular clamping pieces.

(Problems to be Solved by the Invention) In the above-mentioned conventionally known fasteners, the pin that passes through the fastener protrudes rearward, so there is a risk that the tips of the pins will pierce the nape of the neck behind the ear.
With repeated use, the clamping piece of the stopper may wear out or the spring force may weaken, making it impossible to obtain a firm stopper effect, causing the problem that the stopper may come off and fall during use.

In order to solve this problem, it is known that the stopper is made of an elastic material. For example, a stopper is known in which a hollow sphere is filled with an elastic member such as synthetic resin or rubber (Utility Model Publication No. 61-13615).
Publication No.). It is also known that the beads are formed from an elastic material in the shape of a bead, and a decorative skin made of metal foil or the like is provided on the surface (Japanese Utility Model Publication No. 60-6417).

Among these conventionally known fasteners formed of elastic bodies, the above-mentioned spherical ones are difficult to grasp by hand, difficult to control due to their spherical shape, and difficult to determine the direction in which the pin should be inserted, making them difficult to use. In addition to the problem of difficulty in manufacturing,
Since the elastic body must be filled one by one, it is not suitable for mass production and has the problem of increasing costs. Further, even when the decorative skin is formed into a roughly bead-shaped object, the skin has to be attached manually one by one, which also raises the problem of high costs.

In view of the above-mentioned problems with the conventional fasteners, this invention is a new fastener that is highly safe, can maintain the fastening effect for a long time, is easy to use, can be mass-produced, and can be provided at low cost. An object of the present invention is to provide an earring having a component.

(Means for Solving the Problem) Therefore, in this invention, an earring is made up of an ornament fixed to the tip of a pin and a stopper through which the pin is inserted, and the main body of the stopper is made of flexible silicone. The stopper is formed of an elastic body such as resin, the rear half thereof is approximately hemispherical, the pin receiving half is formed in the shape of a circular protrusion, and a pin insertion hole is formed in the center of the elastic body body, It is characterized in that a metal fitting serving as a shell is fitted into the circular protrusion on the pin receiving side of the elastic body main body, the outer shape of which is the same as that of the elastic body, and a through hole is formed at a position that corresponds to the pin insertion hole. It is something.

(Function) In this invention, the pin is fixed by inserting the pin into the pin insertion hole of the stopper made of a flexible elastic body.In particular, since a metal fitting serving as a shell is fitted on the pin receiving side, this To strengthen the pin gripping force of a stopper and maintain that gripping force for a long period of time.

Since the rear half of the stopper is approximately hemispherical and the pin-receiving half is formed into a circular protrusion, it is easy to grasp by hand, and it is easy to find the direction when grasping it by hand. , easy to insert pins.

(Example) The details of the present invention will be explained below with reference to preferred embodiments shown in the drawings.

In the figure, 1 is a decoration fixed to the tip of the pin 2.
In the figure, reference numeral 3 denotes a stopper, whose main body 4 is made of a flexible elastic body. The elastic body is preferably made of silicone resin, but may be made of other materials such as rubber. This stopper main body 4 is, as shown in the figure,
The shape of the rear half is hemispherical, and the pin receiving half 5 is formed in the shape of a circular protrusion. A pin insertion hole 6 is formed in the center of this stopper body 4.

In the figure, reference numeral 7 denotes a metal fitting that becomes a shell, and has the same external shape as the receiving half 5 of the stopper main body, and is fitted into the half 5 to form a shell. A through hole 8 is formed in this metal fitting 7 at a position that coincides with the pin insertion hole 6.

Since the diameter of the pin 2 is usually approximately 0.6 to 0.9 mm, the inner diameter of the pin insertion hole 6 of the stopper 3 is approximately 0.5 mm, and the diameter of the through hole 8 of the metal fitting 7 is approximately 0.9 mm.

The earring of the present invention, which has the configuration as described above,
When the pin 2 is inserted through the through hole 6 of the stopper 3 through the through hole 8 of the metal fitting 7, which is a shell, the elastic body is made of a flexible elastic body.
grasp. Since this gripping force is achieved by fitting the metal fitting 7 serving as a shell, the escape action of the elastic body is prevented, and the pin 2 can be firmly gripped.

(Effects of the invention) As described above, in the present invention, the main body of the stopper is made of a flexible elastic body, a pin insertion hole is formed in this main body, and a shell body is formed with a through hole on the pin receiving side of the main body. Because the pin is fitted with a metal fitting, this fastener firmly grips the pin and maintains its grip over a long period of time, so there is no risk of the fastener falling off during use. Moreover, since the main body of the stopper is made of a flexible elastic body, it does not cause any pain or danger even if it hits the back of the neck behind the ear.

In addition, especially in the present invention, the shape of the stopper is such that the rear half is approximately hemispherical and the pin-receiving half is formed into a circular protrusion, so it is easy to grasp by hand, and the direction of the stopper is easily adjusted when grasped. This has the practical effects of being able to easily and accurately feel the nature of the device, making it easy to insert or remove the pin, and making it easy to use.

Furthermore, in the structure of the earring of the present invention, a large number of molds, for example 100 or 200 molds, are installed in one mold, and the metal fittings 7 are placed in the mold in advance and the elastic body is poured at once. Since the fasteners can be manufactured at one time, mass production is possible, which has the great effect of being able to produce at a lower cost.
