DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chain for an accessory which can provide a new sense of accessory and which can be easily made in various variations.

[0002]

2. Description of the Related Art As a conventional accessory chain, a chain formed by connecting a number of rings having a circular shape, an elliptical shape, a rhombic shape, or the like is generally used. In addition, a chain called Kihei, which has a structure with no irregularities on the surface of the chain, is widely used.

[0003]

However, in the above-mentioned conventional accessory chain, it has been almost impossible to obtain a product which is light in weight but excellent in volume and rich in texture with depth.

The present invention is intended to solve the above-mentioned drawbacks of the prior art, and since the reflecting surface can be diversified and a variety of accessories chains can be obtained, the user is not bored immediately. An object of the present invention is to provide an accessory chain that can be used for a long period of time.

[0005]

In other words, the accessory chain according to the present invention is a ring-shaped precious metal pipe having a circular cross section and a pointed tip converging from the circular section so that the circular section is on the inner peripheral side. And connected to each other.

Further, in the accessory chain according to the present invention, a pipe made of a noble metal having a circular section and a pointed head converged therefrom is formed in a C-shape such that the circular section is on the inner peripheral side. It is characterized in that it is formed in a ring shape by connecting the side surfaces so that the positions of the openings do not match.

Further, the chain for ornaments of the present invention is formed in the shape of a ring by connecting C-shaped noble metal pipes on the side so that the openings are not aligned with each other and slightly shifted in the radial direction. It is also characterized by doing.

[0008]

As described above, according to the present invention, a pipe made of a noble metal having a cross section composed of an arc portion and a pointed head converged from the arc portion,
Since the arc portion is formed in a ring shape on the inner peripheral side and connected so that the reflecting surface is diversified and it is possible to obtain a variety of accessories chains that are rich in various changes, it is quickly got tired. It has become possible to provide a jewelry chain that can be used for a long time without being lost.

Furthermore, it is possible to provide a chain for accessories that is lightweight, easy to handle, and excellent in volume despite being used for a long time, and is rich in texture with depth. .

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

FIGS. 1 and 2 are views for explaining the accessory chain of the present invention. Reference numerals 1, 1 'denote precious metal pipes having a cross-section consisting of an arc portion 2 and a pointed tip 3 converged therefrom. It becomes a chain element constituting the chain for accessories. Although the noble metal pipes 1 and 1 'are formed in the above-described shape in the figure, the ratio between the arc portion 2 and the point 3 converged therefrom is determined in consideration of the reflectance of the both sides of the point 3 and the like. It can be determined appropriately.

The precious metal pipes 1, 1 'are made of gold, silver,
It is desirable to select from materials such as platinum and alloys thereof and use them alone or in combination as appropriate according to the application and desired strength.

The noble metal pipes 1 and 1 'can be obtained by drawing a predetermined shape into a predetermined shape and cutting the same into a predetermined length using a cutting machine.

In the figure, the precious metal pipes 1 and 1 'are formed in a substantially C-shape so that the arc portion 2 is on the inner peripheral side. It is formed in a ring shape by being connected at the side surface. Therefore, since light is reflected from both surfaces of the pointed head 3 at a fixed angle, a chain element rich in shadows can be obtained.

In the figure, a pair of C-shaped noble metal pipes 1 and 1 ′ are further formed in a ring shape by connecting them on the side surfaces while being slightly shifted in the radial direction. By particularly assembling the pair of noble metal pipes 1 and 1 'in this manner, the reflecting surface such as the pointed head 3 can be diversified, and the chain element 11 rich in various changes can be obtained.

When connecting a pair of noble metal pipes 1 and 1 'to form a ring by connecting the side surfaces, the degree of radially shifted connection is determined by the size of the chain element 11 and the required reflectance. It can be appropriately determined in consideration of such factors.

The connection of the side surfaces of the precious metal pipes 1 and 1 'is usually carried out by brazing, but it goes without saying that it may be carried out by laser welding or other means. At this time, the thickness of the precious metal pipes 1, 1 'must be at least resistant to brazing, laser welding, and the like. Care must be taken to ensure that no deformation occurs.

FIG. 3 shows a jewelry chain formed by assembling the chain element 11 described above. That is, the pair of noble metal pipes 1 and 1 ′ are connected at their ring portions, and are connected so as to engage with each other in the C-shaped opening 4.

When connecting the chain element 11, a chain element 11 obtained by connecting a pair of noble metal pipes in a ring shape in advance by side is prepared. Then, the precious metal pipe 1 formed in a C-shape is fitted and connected from the opening 4 and another precious metal pipe 1 ′ is joined so as to mesh with the C-shaped opening 4. , 1 ′ are connected on the side surfaces by brazing, laser welding, or the like to form a ring shape to obtain the next chain element 21.

In the next stage, the C-shaped noble metal pipe 1 is inserted through its opening 4 into the two chain elements 11,
21 and the other noble metal pipes 1 'are joined so as to engage with the C-shaped opening 4, and the pair of noble metal pipes 1 and 1' are connected at the side surfaces by brazing or laser welding. Thus, the next chain element 31 is obtained by forming into a ring shape.

At this time, the noble metal pipe 1 is connected so as to mesh with the noble metal pipe 1 'of the first chain element 11 of the two chain elements 11, 21 and the next chain element (not shown).
Of the noble metal pipe 1 of the second chain element 21 so as to engage with each other. Then, since each noble metal pipe 1 is fitted into the opening 4 of the two precious metal pipes 1 and positioned, the two chain elements 11 and 31 are connected so as to form a substantially right angle.

The obtained accessory chain is composed of the respective chain elements 11, 21 and 21.
31 are connected in such a manner that they are shifted by about 45 ° in the radial direction, so that they appear to be connected spirally as a whole. The reflecting surface such as the pointed head 3 constituting the chain element 11 can be diversified to obtain a variety of accessories chains for various accessories, and can be used for a long time without being tired of immediately. Can be provided.

[0023]

As described above, according to the present invention, a pipe made of a noble metal having a circular section and a pointed head converged therefrom is formed in a ring shape such that the circular section is on the inner peripheral side. Since the reflection surface is diversified and various kinds of chains for personal accessories can be obtained because the reflecting surface is diversified, it is possible to use the personal accessories for a long time without being tired immediately. Chains can now be provided.

Furthermore, it is possible to provide a chain for accessories that is lightweight, easy to handle, and excellent in volume even though it is hard to be worn out even when used for a long time, and is rich in texture with depth. .
