DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative chain used as a necklace, a bracelet, an eyeglass holder, or the like, in which a thin tube is connected between main body chains.

[0002]

2. Description of the Related Art In recent years, magnetism is said to improve blood circulation of muscle tissue and soften hardened muscles, and magnets are sometimes attached to decorative chains. For example, when a magnet is attached to a ball chain, as shown in FIG.
After the magnet 2 is fitted into the hole 1a, the half of the ball 3 of the ball chain is fitted into the end of the hole 1a of the thin tube 1, and finally the thin tube 1 and the ball 3 are joined by the brazing metal material 4. It has become.

[0003]

However, in the above-mentioned conventional example, since half of the ball 3 protrudes from the thin tube 1 and the metal material 4 remains on the surface of the ball 3,
There is a problem that decorativeness is impaired. Ball 3
Is fixed to the thin tube 1 so as not to rotate, so that there is a problem in that the range in which it does not bend is widened. Further, when the ball 3 is brazed to the thin tube 1 with the metal material 4, the heat of the brazing operation may be transmitted to the magnet 2, and the magnetism of the magnet 2 may be lost.

An object of the present invention is to solve the above-mentioned problems and to provide a decorative chain with improved decorativeness.

[0005]

According to a first aspect of the present invention, there is provided a decorative chain in which a thin tube is connected between main body chains, wherein the main chain is fitted into a hole of the thin tube. The main chain and the thin tube are connected by crimping an end of the thin tube inward in the combined state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in FIGS. FIG. 1 is a partial perspective view of the first embodiment, in which thin tubes 11 are arranged at various places in a main chain 10 composed of a ball chain. The main body chain 10 is formed by connecting spherical bodies 13 of the same material in a universal joint shape by connecting rods 12 made of, for example, gold.
The thin tube 11 made of the same material as the material 0 is rotatably connected to the spherical body 13 at the end of the main chain 10. Attachments 14 that are attached to the vine of the glasses are connected to the ends of the main body chain 10, respectively.

As shown in the partial sectional view of FIG.
2 are formed with flange portions 12a at both ends, and a spherical body 13 is formed around the flange portions 12a of the adjacent connecting rods 12.
Is processed into a shell shape, whereby the connecting rods 12 are connected in a universal joint shape.

As shown in the partial sectional view of FIG.
Reference numeral 4 denotes a rubber ring 16 inserted through a center hole 15a of a ring 15, an inner portion 16a of the rubber ring 16 is connected to a flange portion 12a of an outermost connecting rod 12 via a small ring 17, and an outer portion of the rubber ring 16 is provided. A temple of glasses is inserted through 16b. The ring 15, the rubber ring 16 and the small ring 17 are also provided with decorativeness. For the rubber ring 16, for example, reinforced silicon rubber or the like is used.

Here, as shown in a partial sectional view of the thin tube 11 of FIG. 4, the thin tube 11 is slightly curved,
In one hole 11a, for example, two magnets 22 are inserted with a flexible tube 21 interposed therebetween. And magnet 2
Substantially the entirety of the spherical body 13 at the end of the main chain 10 is fitted on both sides of 2, and thereafter the end of the thin tube 11 is swaged to form a swaged portion 11b. Thereby, the thin tube 11 and the spherical body 13 are connected in a universal joint shape. At this time, as the size of the caulked portion 11b increases, the amount of protrusion of the spherical body 13 from the thin tube 11 can be reduced. The bending of the thin tube 11 is performed after these processes are completed.

When the decorative chain constructed as described above is used, the outer portions 16 of the rubber rings 16 of the two attachments 14 are used.
Insert the vine of the glasses through b, and move the ring 15 to the vine side of the glasses to fix the fixture 14 to the glasses. And
Glasses are put so that the thin tube 11 is located on the rear side of the neck. At this time, since the thin tube 11 is curved, it is easy to adhere to the neck, and the magnetism of the magnet 22 works well on the neck.

As described above, in the first embodiment, the connecting rod 12
Are connected to each other by a spherical body 13 in a universal joint shape,
Substantially the entire spherical body 13 at the end of the main body chain 10 is a thin tube 1
After fitting into the hole 11a, the end of the thin tube 11 is swaged,
The caulking portion 11b connects the thin tube 11 and the spherical body 13 in a universal joint shape. Therefore, substantially the entire spherical body 13 can be fitted into the hole 11a of the thin tube 11, and the brazing portion as in the related art can be eliminated, so that the decorativeness can be improved. Further, since the thin tube 11 and the spherical body 13 are connected in a universal joint shape, the range that can be bent can be made wider than before. Further, since no brazing operation is involved, the temperature of the magnet 22 is not increased, and the magnetism of the magnet 22 is not lost.

FIG. 5 is a partial sectional view of the second embodiment.
A thin tube 31 is provided in some places on the main chain 30 composed of a rod chain.
Are connected. The rod 3 at the end of the main body chain 30
A spherical portion 32a and an annular groove 32b are sequentially formed from the end of the second end by, for example, press working. Then, the spherical portion 32a of the rod 32 is fitted into the hole 31a of the thin tube 31, and the end of the thin tube 31 is caulked in the annular groove 32b, so that the main chain 30 and the thin tube 31 are connected. The second embodiment can also achieve the same effects as the first embodiment.

FIG. 6 is a partial sectional view of the third embodiment.
Narrow tubes 41 are connected to various parts of the main chain 40 composed of a snake chain. And the hole 41a of the thin tube 41
The main body chain 40 and the thin tube 41 are connected by inserting the end 42 of the main chain 40 into the concave portion 42 a between the ends 42 of the thin tubes 41. At this time, if the thin tube 41 is swaged so as to eliminate the gap between the main chain 40 and the thin tube 41, the connection is further ensured.

The third embodiment differs from the third embodiment in that the connection between the main body chain 40 and the thin tube 41 does not form a universal joint.
An effect similar to that of the above-described embodiment can be obtained.

In the above embodiment, the ball chain 1
0, thin chain 1 on rod chain 30, snake chain 40
Although the decorative chain in which 1, 31, and 41 are respectively connected has been described, the present invention can also be applied to any main body chain having a shape that can be connected by caulking the ends of the thin tubes 11, 31, and 41. It is.

Also, although the description has been made for glasses, the lengths of the main chains 10, 30, and 40, the capillaries 11, 31, and 4,
It is needless to say that by appropriately determining the length and number of one, it can be used as a necklace, a bracelet, or the like. Further, although the thin tubes 11, 31, and 41 are curved, they may be straight, but there is no problem, and the number of magnets 22 may be one, three or more, or not used.

[0017]

As described above, in the decorative chain according to the present invention, the main chain and the thin tube are connected by crimping the end of the thin tube inward with the end of the main chain fitted into the thin tube. As a result, substantially the entire end of the main chain can be fitted into the thin tube, and the conventional brazing portion can be eliminated, so that decorativeness can be improved.
