Description

[Detailed description of the invention] Industrial field of application This invention is a method for attaching and fixing jewelry, etc., to a thin-walled metal hollow body having no openings, such as a sphere, an elliptical sphere, a heart-shaped body, or any other suitable shape. It is related to accessories.

Conventional Technology Conventionally, hollow metal earrings, brooches, tie pins, and other accessories of this kind, which are hollow spheres, are usually made of gold, silver, platinum, or other precious metals, or metals such as metal plating or brass. Since it is a thin item and is necessarily used as an accessory, it is not suitable for practical use if it is too large, and it is made of expensive precious metal, so it is necessary to use as little material as possible. Since it is required to be light enough to be worn on the body without causing any problems, it is necessarily small to some extent (a diameter of approximately 3 mm to 30 mm is most commonly used).
It is also hollow, thin, and lightweight.
For this reason, for example, even if you attach it to the surface of this type of hollow body using a method such as a rouzuke, the hollow body is small and thin, so it will easily peel off and fall off during use. Even if you try to do so, the air inside the hollow body expands and deforms due to the heating during waxing, and the air pressure causes the jewels etc. that have been attached to the hollow body to be blown off and fall off, or even if they are attached again. However, since the hollow body is thin, sufficient adhesion force cannot be obtained, and it will fall off if it comes into contact with something even slightly hard during use.It is common knowledge in the industry that jewelry, etc. cannot be attached to this type of hollow body. For this reason, methods such as making the inside of the sphere solid or providing an opening for venting air were used.

Problems that the invention aims to solve Conventionally, even if a hole is made in a thin hollow body to attach jewelry, etc., the air inside expands due to heating during waxing and the air blows out, or it is difficult to attach and fix it at all costs. However, since the hollow body is thin, sufficient adhesion force cannot be obtained, and it is not possible to obtain a hollow body to which jewelry, etc. is attached and fixed so as to have sufficient adhesion force to a satisfactory degree so that it will not fall off easily. There was.

Means for Solving the Problems The object of the present invention is to provide a hollow body to which a jewel or the like is securely attached and fixed with sufficient adhesion force to the extent that it does not easily fall off.

The present invention will be explained based on the drawings showing one embodiment thereof.

1 is a hollow body made of gold, silver, platinum, or other precious metals, or a hollow, thin-walled sphere made of metal such as brass, or brass;
It is formed into an elliptical sphere, a heart-shaped body, and other appropriate shapes.

Reference numeral 2 denotes a through hole, which is bored at an arbitrary position in the hollow body 1.

Reference numeral 3 denotes a fixing rod, which is a rod made of a suitable metal such as gold, silver, platinum or other precious metals, or brass.

Reference numeral 4 denotes a mounting portion, which is formed into a concave dish-shaped cross section and is integrally connected to the tip of the fixing rod 3 so that jewelry or the like can be easily mounted and fixed.

5 is a hollow body 1 by bulging a part of the through hole 2 to form a small hole 6 as shown in FIG.
It has a hole in it.

The fixing rod 3 is inserted into the hollow body 1 through the through hole 2, and its root 3a is brought into contact with the inner surface of the hollow body 1 on the opposite side of the through hole 2 (as shown in FIG. 2). 3 and the inner surface of the hollow body 1 are fixed together with a wax 7.

The wax 7 may be a soft wax, but in order to provide sufficient strength, a hard wax made of silver is most suitable, but methods such as brass wax or German silver wax may be used as necessary.

Further, as shown in FIGS. 6 and 7, solder such as silver solder is attached to the root part 3a of the fixing rod 3 in advance in the wax 7, and the solder is inserted into the hollow body 1 through the through hole 2.
The root portion 3a of the fixing rod 3 is brought into contact with the inner surface of the hollow body 1, and as shown in FIG.

Further, instead of the flame waxing method, electric heating may be used.

Heating according to this waxing method involves heating at a temperature of about 750° C. or higher, which is necessary for melting the waxing agent.

4 and 5 show air vent holes 5 in which vertical grooves 8 are formed in the fixing rod 3 in the length direction without drilling holes in the hollow body 1.

In this case, the vertical groove 8 is recessed and communicated with the lower surface of the mounting portion 4.

In this way, it is not necessary to provide the small hole 6 in the hollow body 1 in a continuous manner with the through hole 2.

Furthermore, in FIGS. 12 to 13, the fixing rod 3 is formed to have a polygonal cross section such as a triangle or a square, the through hole 2 of the hollow body 1 is formed circularly, and the space between the through hole 2 and the fixing rod 3 is 14 and 15, the through hole 2 is formed in a polygonal shape such as a triangle or square, and the fixing rod 3 is formed in a circular cross section for air venting. The interval 5 is formed.

In this way, it is not necessary to form small holes 6 and vertical grooves 8 as air vent holes 5 in each through hole 2 and fixing rod 3.

After the root portion 3a of the fixing rod 3 and the inner surface of the hollow body 1 are waxed 7, the through hole 2 and the fixing rod 3 may be waxed 7 if necessary.

8 and 9 show that the hollow body 1 is formed into an ellipsoidal or diamond-shaped cross section, and in FIGS. 10 and 11, the hollow body 1 is formed into a heart-shaped body or a flower leaf shape.

Effects of the invention Since the invention is constructed as described above, no matter how thin the hollow body is, no matter how thin the hollow sphere is, no matter what shape it is, or even if the diameter is small, jewelry etc. can be easily and firmly attached. It has the effect of being able to be fixed.

Furthermore, since the air vent gap 5 is provided between the through hole 2 and the fixing rod 3, even if the hollow body is heated from the outside surface to prevent waxing, the heated and expanded air is easily exhausted to the outside. Because of this, there is no fear that the hollow body will be deformed due to the air pressure inside it heated and expanded, or that the fixing rod will be blown off and fall off.
