Abstract

PROBLEM TO BE SOLVED: To improve value as article by molding/working the main body of earing into prescribed shape by performing the press working of plate or stick of noble metals, integrally forming a projection at any suitable position of the main body of earing and fitting a stopper, which moves back and forth toward an earlobe, to a hollow body. SOLUTION: An earing 21 is composed of a main body 1 of earing to which decorativeness is applied, hollow body 2 formed at one end of the main body 1 of earing, stopper 3 fitted to the hollow body 2, and a receiver plate 4 formed by turning over the other end of the main body 1 of earing. Concerning the main body 1 of earing and the hollow body 2, the projection is squeezed out at the end by performing press working while using the plate or stick of noble metals. Next, the section of the receiver plate 4 is formed by further performing press working to the plate or stick of noble metals while including the section of the projection extended outside, increasing the height of the projection through squeeze working and simultaneously thinning the other end of the main body 1 of earing through press working. A female screw is formed at the projection and the stopper 3 is fitted into the hollow body 2 composed of such a projecting section.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention particularly relates to an earring called a screw type, and an object thereof is to provide an earring in which the durability of a pipe-shaped portion to which a screw screw or the like is attached is greatly improved.

[0002]

2. Description of the Related Art In a conventional screw-type earring, a pipe-like female screw to which a screw screw or the like is attached is brazed to one end of the main body of the earring, and then a stopper for moving forward and backward toward the earlobe is attached to the female screw part. It was.

[0003]

Conventionally, the heat treatment at the time of brazing has the disadvantage that the pipe-shaped female screw has poor durability. For this reason, ear decorations cannot be used for a long time.

In particular, when an attempt is made to form a screw-type earring using pure silver, pure gold, pure platinum, or the like containing only a trace amount of impurities, a female screw portion is deformed when a load is applied, and is not usable. There was a problem that it was difficult to become.

Therefore, if a pipe-shaped female screw is made of pure silver, pure gold, pure platinum, or the like, and this pipe-shaped female screw is subjected to a heat treatment when brazing it to the main body of the ear decoration, the female screw cannot be used at all. It is not hard to imagine.

This invention is intended to solve the above-mentioned drawbacks of the prior art, in which a noble metal plate or a rod is pressed to form an ear ornament body into a predetermined shape, and a projection is integrally formed at an appropriate position of the ear ornament body. Then, the above-mentioned projections are subjected to hollow processing, and a stopper is attached to this,
An object of the present invention is to provide an earring with high commercial value without loss of hardness due to plastic hardening.

[0007]

That is, according to the present invention, an earring is formed by pressing a noble metal plate or a rod to form the main body of the earring into a predetermined shape, and integrally forming a projection at an appropriate position on the main body of the earring. The projection is subjected to hollow processing, and a stopper that advances and retreats toward the earlobe is attached to the hollow body.

The earring according to the present invention is also characterized in that the noble metal plate or rod is made of a high-purity noble metal such as pure silver, pure gold or pure platinum.

The earring according to the present invention is also characterized in that the projection integrally formed at an appropriate position of the earring body is formed with a female screw in the hollow body.

Further, the earring according to the present invention is characterized in that the stopper attached to the hollow body has a knob screwed to one end.

Since the earring according to the present invention is constructed as described above, it is possible to provide an earring having a high commercial value without losing the hardness due to plastic hardening by eliminating heat treatment.

The earrings of the present invention are particularly effective for earrings made of pure silver, pure gold, pure platinum or the like containing only a trace amount of impurities. Originally, the material is plastically hardened by applying pressure such as pressing to the material. Without lowering the hardness of the material that had increased the hardness using
Moreover, it has become possible to provide ear ornaments with a glossy luster and a very high commercial value.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of an earring according to an embodiment of the present invention;

FIG. 1 is a side view showing an entire earring according to the present invention. In the figure, an earring 21 is composed of an ornamental body 1 provided with a decorative property, a hollow body 2 integrally formed at one end of the earring body 1, and a stopper 3 attached to the hollow body 2. I have. Reference numeral 4 denotes a receiving plate formed by folding the other end of the ear decoration body 1 and integrally forming the same.

The earring 21 is manufactured as follows.

The ear decoration body 1 and the hollow body 2 are pressed using a noble metal plate or rod 11 made of a noble metal of high purity such as pure silver, pure gold, pure platinum or the like as shown in FIG. The projection 12 is squeezed out at one end.

Next, as shown in FIG. 5 and FIG.
The noble metal plate or rod 11 is further subjected to press working, including the portion extending to the outside of 2, and the height of the projections 12 is increased by drawing, and at the same time, the other end of the ear decoration main body 1 is squeezed finely by press working. To form a site.

In the case of a small product or the like, the above-mentioned press working requires only about one to three steps, but a large or complicated product requires several or more steps. Sometimes it becomes.

Next, as shown in FIG. 7, a hollow 12 is formed on the projection 12 formed to a predetermined length by using a screw tap or a mechanical tap, and by performing thread cutting. As shown in FIG. 1, a stopper 3 made of a screw screw is fitted into the hollow body 2 composed of the projection 12 thus formed. A holding plate 5 is formed at one end of the stopper 3 in advance against the receiving plate 4, and a knob 6 is fixed to the other end of the stopper 3 which is inserted into the hollow body 2 and protrudes from the opposite side. The knob 6 can be fixed by screwing via a lock material. Further, for example, as shown in FIG. 8, it is also possible to fix by screwing with a small screw 7 or the like.

It is desirable that the earring body 1 be formed into a predetermined shape by press working from the viewpoint of increasing the plastic hardening of the noble metal plate or rod 11 made of a high-purity noble metal such as pure silver, pure gold or pure platinum. Note that the earring body 1
Needless to say, the processing into the predetermined shape may be performed before or after the attachment of the stopper 3 to the hollow body 2.

The earring 21 of the present invention can be used in the same manner as a conventional screw-type earring. That is,
By turning the knob 6, the stopper 3 consisting of a screw screw is retracted, the gap between the holding plate 5 and the receiving plate 4 at the tip is widened, and the earlobe is inserted therebetween. Next, the knob 6 is turned in the opposite direction to advance the stopper 3, and the earlobe is pinched between the holding plate 5 and the receiving plate 4 at the tip. To remove the earring 21 from the earlobe, the operation opposite to the above may be performed.

[0022]

Since the earring of the present invention is constructed as described above, it is possible to provide an earring having a high commercial value without losing the hardness due to plastic hardening without heat treatment.

The earring according to the present invention is particularly effective for an earring made of pure silver, pure gold, pure platinum or the like containing only a trace amount of impurities. Without lowering the hardness of the material that had increased the hardness using
Moreover, it has become possible to provide ear ornaments with a glossy luster and a very high commercial value.
