Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to the improvement of jewelry made by connecting metal round balls into a chain.

[0002]

[Prior art]

 Conventionally, there has been a necklace or a bracelet in which a metal round ball is connected with a connecting yarn represented by a wire or a nylon yarn to form a chain. Some round metal balls have diamonds or the like fitted therein. However, when worn around the body as a necklace or the like, it is inevitable that the diamond is rotated around the connecting yarn, and the bent diamonds are often directed in different directions without facing the front.

[0003]

[Problems to be solved by the invention]

 The present invention has been made in view of such a conventional technique, and an object of the present invention is to attach a metal round ball to a body in a state where the ball is oriented in a desired direction.

[0004]

[Means for Solving the Problems]

 The gist of the present invention is to provide a chain-shaped accessory which is formed by piercing a metal round ball, passing a connecting thread through the hole, and having fasteners at both ends thereof, wherein a part of the metal round ball is substantially flat. It is characterized by having done.

[0005]

[Embodiment of the invention]

 The greatest feature of the present invention is that a substantially flat portion is formed on a round metal ball. Therefore, when the substantially flat portion side is worn on the body side, the round ball is less likely to rotate around the connecting yarn, and the round ball is kept at a desired position. For this reason, if precious stones or the like were fitted into the part corresponding to the flat part of the round ball, the decorativeness would be increased because the precious stone would always be located in front of the body as usual. .

[0006] The metal round ball used may be a hollow body or a solid body. In the case of a hollow body, a round ball is formed by welding a hemispherical body. Although this metal round ball is not particularly limited, it is generally 18 gold, and is also composed of platinum, silver and the like. When the round ball is a hollow body, a substantially flat portion is easily formed, and a configuration in which a precious stone is fitted is easily adopted. Precious stones are also not particularly limited, and diamonds are particularly preferred. It goes without saying that it is preferable to insert precious stones on the side corresponding to the substantially flat portion. In the case of a round ball obtained by welding two hemispheres, a substantially flat portion is formed in one of the hemispheres in advance, and a depression is formed in the other hemisphere. Is to be fitted.

In order to make the metal round ball particularly difficult to rotate, it is better to devise the shape of the hole to be drilled in the round ball, and if it is a simple round hole, it is easy to rotate around the connecting yarn. Therefore, the shape of the hole of this perforation is made elliptical, square (preferably rectangular), triangular, or the like. Of course, the connecting yarn side also has a cross section adapted to this shape, that is, for example, Hikkomaru It is a chain or a rectangular chain. As the connecting yarn, a synthetic fiber typified by a thin metal wire or a nylon yarn is used. Of course, these may be a single wire, a double wire, or a chain as described above. is there.

【Example】

 Hereinafter, the accessory of the present invention will be described in more detail with reference to the drawings. FIG. 1 is an exploded view of the chain accessory of the present invention. 1 is a hollow round ball of 18 gold, 2 is a wire (connecting thread) penetrating through a perforated portion formed in the round ball 1, 3 is a round ball 1, 1 is a urethane bead sandwiched between 1, 4 and 5 are clasps. is there. The round ball 1 has a substantially flat portion 6 formed in a direction perpendicular to the wire 2. For this reason, if the flat portion 6 is attached to the body, it does not rotate around the wire 2 and the round ball 1 can maintain a constant orientation in a normal state. In addition, various types of fasteners 4 and 5 other than those described above are used, and there is no particular limitation.

FIG. 2 is an enlarged sectional view showing only the round ball, and FIG. 3 is a side view thereof. The round ball 1 is formed by welding two hemispheres 1a and 1b. The hemisphere 1a has a flat portion 6 at the top. As shown in FIG. 4, the hemisphere 1a obtained by, for example, press working is fitted into a lower jig M1, and the flat portion 6 can be formed simply by pressing the same. M2 is an upper jig for pressing the hemisphere 1a.

On the other hand, as shown in FIG. 5, the hemisphere 1b presses an upper jig M3 having a pointed head to form a V-shaped recess 1c, and a diamond D is fitted into the V-shaped recess 1c. The edge 1d is pressed and deformed by the upper jig M4 to fix the diamond D in the depression 1c.

The hemisphere 1a thus formed and the other hemisphere 1b are welded to the edge 1e. This welding method is optional.

A perforated portion 7 is formed between the flat portion 6 and the diamond D so as to pass the wire 2, and the wire 2 is passed through the perforated portion 7. For example, as shown in FIG. The portion 7 has an elliptical shape that is long in the lateral direction, and it is preferable that the wire 2 also has an elliptical shape (Hirakkomaru). Of course, the perforated portion 7 may have an elliptical shape that is long in the vertical direction.

In the chain-shaped accessory of the present invention, all the round balls are shown with round balls in which diamonds D are fitted. However, it is needless to say that the present invention is not limited to this, and that diamonds are not fitted. It goes without saying that only simple round balls may be used, or these may be combined to form a chain.

[0014]

[Effects of the Invention] The chain-shaped jewelry of the present invention has excellent decorativeness because the round ball does not normally rotate and its direction is always constant when worn on the body.
