Abstract

PURPOSE:To obtain a composite medal, which is abundant in fashionability, originality and variety as an ornament, and has a stable property value, by a method wherein on the inside of an outer frame made of a kind of noble metal, a plate member made of another kind of noble metal is arranged and some gaps are allowed to remain between them, and both the plate member and the outer frame are integrally joined with calk pins made of another kind of noble metal. CONSTITUTION:A composite medal 8 consists of an outer frame 4 made of a kind of noble metal, a plate member 5 made of another kind of noble metal, which is arranged in order that some gaps remain between the inside of the outer frame 4 and the contour of the plate member 5, and calk pins 7 made of another kind of noble metal, with which the plate member 5 and the outer frame 4 are integrally joined at the gaps between them. In this way, since variation can be obtained in hues and shapes of different kinds of these noble metals inside and outside, the medal is abundant in fashionability, originality and variety. In addition, characteristics and peculialities of these noble metals are individually held and the composite medal with a stable property value can be obtained. Furthermore, when the calk pins are removed, these noble metals inside and outside can be easily separated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite medal as a decorative item.

[0002]

2. Description of the Related Art Conventionally, as a composite medal, there has been one in which a ring 2 made of another noble metal is fitted and joined to the outer periphery of a noble metal medal 1 as shown in FIG. However, this composite medal 3 was poor in fashionability, originality, and variety as an ornament.

On the other hand, in recent years, medals have been increasingly used as ornaments, and there is a strong demand for medals that are rich in fashionability, originality, and variety.

In addition, the demand for ornaments as the asset value of Au and Pt is also increasing. Especially, in order to avoid the risk of the price fluctuation of Pt, the price stability of Au is utilized,
There is also a demand for products that can sell Pt as a set.

[0005]

Therefore, the present invention intends to provide a composite medal which is rich in fashionability, originality, and variety as an ornament, retains the characteristics and characteristics of a plurality of precious metals, and has a stable asset value. To do.

[0006]

A composite medal of the present invention for solving the above-mentioned problems is provided with an outer frame made of a noble metal and inside the outer frame with a slight clearance from the inner shape. Another noble metal plate member and yet another noble metal caulking pin which is formed by combining and integrating the plate member and the outer frame in the gap between the plate member and the outer frame.

[0007]

[Function] Since the composite medal configured as described above can change the hue and shape of a plurality of precious metals inside and outside, it is rich in fashionability, originality and variety as an ornament. In addition, the characteristics and characteristics of each precious metal can be retained, and a compound medal with stable asset value can be obtained. Moreover, by removing the caulking pin, the precious metal inside and outside can be easily separated.

[0008]

EXAMPLE An example of the compound medal of the present invention will be described with reference to the drawing. As shown in FIG. 1, the outer shape is a circle with a diameter of 25 mm, the inner shape is a square with a side of 16 mm, and the thickness is 1.5 mm of Pt. Inside the outer frame 4, a disc 5 made of Au having a diameter of 16 mm and a thickness of 1.5 mm is arranged as shown in FIG.
3 mm in diameter and 3.0 m in height at the gap 6 with the four corners of the rectangle
A pin 7 made of Ag of m was fitted, the upper and lower ends were crushed, and the disk 5 and the outer frame 4 were caulked as shown in FIG.

Although the inner shape of the outer frame 4 in the composite medal 8 of the above embodiment is square, it may be triangular, pentagonal or hexagonal as shown in FIG. It may be circular as shown in. Further, it is preferable that the caulking is 3 to 5 points, and the fixing and holding of the outer frame 4 and the disk 5 are weak at 2 points, and if the number is 6 or more, it is difficult to remove and the caulking is troublesome. Further, the pin 7 for caulking is not limited to Ag, and it is preferable to use a material having high mechanical strength such as Ag-Cu 7.5% and Ag-Cu 10%.

[0010]

As can be seen from the above embodiments, the composite medal of the present invention can change the hue and shape of a plurality of different precious metals inside and outside, so that it can be fashionable and original as a decorative item such as a necklace. , It will be rich in variety. In addition, the characteristics and characteristics of each precious metal can be retained, the risk of Pt price variability can be avoided by Au price stability, and a stable medal value composite medal can be obtained. In addition, the precious metal disc inside can be easily taken out by removing the caulking pin, so it can be exchanged for cash, and if ready-made coins are used for the precious metal disc, the asset value will be further enhanced and exchange will be easy.
