Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to an improvement in the structure of a cored necklace (including a bracelet).

[0002]

[Prior art]

 A normal necklace is made of a single braided chain, but there is also a cored necklace in which there is a precious metal outside the core chain and the inner core chain is covered by the precious metal. There is.

FIG. 3 is a perspective view showing a conventional method of manufacturing a cored necklace. First, the pipes 1a, 1b, 1c, ... Cut into a certain size with a cutter and cut into slices.

Then, as shown in (3), the core chains 3 having a shape suitable for the ring-shaped ring 2 are inserted into the respective rings 2 and the rings 2 having the same shape are packed without any gap. Then, a molding press is performed to complete a rod-shaped necklace with a core.

[0005]

[Problems to be solved by the device]

 However, it takes time and labor to deburr the cut ends of each ring 2 cut by a cutter and to insert the core chain 3 into a large number of rings 2, resulting in a high manufacturing cost.

Further, there is a problem that a gap is generated between the core chain and each ring during use by the consumer, and the core chain comes loose, and the defect occurrence rate is high.

The technical problem of the present invention is to pay attention to such a problem, to realize a coreless neckless which is easy to manufacture and can be provided at a reasonable price, does not cause problems such as loosening, and has a low failure rate. To do.

[0008]

[Means for Solving the Problems]

 The technical problem of the present invention is solved by the following means. According to a first aspect of the present invention, there is provided a cored necklace characterized in that a tape-shaped body made of a noble metal is spirally wound around a preliminarily machined core chain.

As described above, since the tape-shaped body made of a noble metal is spirally wound around the core chain that has been machine-knitted in advance, the appearance is rod-like, but it is highly flexible, and the necklace or bracelet is very flexible. Easy to use as etc.

Since the work of winding the tape-like body around the core chain can be mechanized, the manufacturing cost is lower than that of the conventional pipe cutting, deburring, or inserting the core chain into many rings. It can be greatly reduced.

A second aspect of the present invention is a cored neckless in which a tape-shaped body made of a noble metal is spirally wound around the pre-machined core chain of the first aspect, and finishing is performed. In this way, since the tape-shaped body wound in a spiral shape is finished, the protrusions and irregularities are adjusted, and the appearance can be finished without being caught. Also, it does not come loose, and there are few defects during use.

A third aspect of the present invention is a cored necklace in which the machine-knitted core chain according to the first or second aspect is preformed so as to obtain a predetermined cross-sectional shape. In this way, since the core chain is machined in advance, it is possible to obtain a desired cross-sectional shape, and as a result, the appearance becomes a shape similar to that of the core chain, and a cored necklace with a desired design can be obtained. it can.

The necklace according to the present invention may include a bracelet.

[0014]

[Embodiment of the invention]

 Next, an embodiment of how the cored necklace according to the present invention is actually embodied will be described. FIG. 1 is a view showing a method of manufacturing a cored necklace according to the present invention in the order of steps.

There is no problem if the core chain has a desired shape from the beginning, but if it is not, first, a machine-knitted chain chain chain chain 4 as shown in (1) is used. By shaping in the shaping step of (2), a core chain 4a having a cross-sectional shape as in (3) is, for example, circular.

Next, as shown in (4), the tip of the tape-like body 5 made of a noble metal is positioned and clamped and fixed to the circular core chain 4a. Then, as shown in (5), when the tape-shaped body 5 is spirally wound by rotating (rotating) the core chain 4a in one direction, the tape-shaped body 5a in the wound state is permanently deformed. Fixed. Finally, the end of the tape-shaped body 5a and the core chain 4a are fixed by caulking with a stopper.

(6) is a perspective view after the tape-shaped body 5 is wound on substantially the entire length of the core chain 4a, and 5a is the tape-shaped body in a spirally wound state. In this way, if the tape-shaped body 5a is still wound, there may be protrusions and it may be caught or irregularities may be created. Therefore, the finishing process of (7) is carried out, and by applying pressure from the outer periphery, finishing shaping is performed. To do.

[0018] (8) is a cross-sectional view of the finished cored necklace, which is finished, in which the tape-like body 5a spirally wound around the outer periphery of the core chain 4a is finished by finishing. It is in close contact with the chain 4a, and the projections and irregularities are shaped and removed.

The tape-shaped body 5 is thin and has a thickness of about 0.2 mm and a width of about 1 mm, but the size is not particularly limited. Since the core chain 4a is covered with the tape-shaped body 5a, an inexpensive chain is sufficient as the core chain 4a, but the tape-shaped body 5a is always exposed to the outside, so that it is as beautiful as possible. It is desirable to use precious metals.

FIG. 2 is a perspective view of various cross-sectional shapes of the core chain and a coreless neckless using the core chain. The core chains 41, 42 ... Are illustrated on the upper side and the core chains are illustrated on the lower side. The external appearance of the cored necklace in a completed state corresponding to the core chains 41, 42, ...

As described above, when the tape-shaped body is wound around the core chains 41, 42, and then finishing is performed, the tape-shaped body 5a in the wound state is shaped to follow the outer shape of the core chains 41, 42. Therefore, an appearance similar to the cross-sectional shape of the core chains 41, 42 ... Is obtained.

The cored necklace of the present invention may be manufactured by winding the tape-shaped body 5 in a state in which two or more kinds of core chains 41, 42, ... As shown in FIG. 2 are connected at a predetermined interval. it can.

[0023]

[Effect of the invention]

 According to claim 1, since it has a structure in which a tape-shaped body made of a noble metal is spirally wound around a pre-machined core chain, it has a stick-like appearance, but is highly flexible and can be used as a necklace or bracelet. Easy to use.

Since the work of winding the tape-like body around the core chain can be mechanized, the manufacturing cost can be reduced as compared with the conventional work of cutting the pipe, deburring, and inserting the core chain into many rings. It can be greatly reduced.

According to the second aspect of the present invention, since the tape-shaped body wound in a spiral shape is finished, it is not caught by the projection and the outer shape is adjusted. In addition, it does not come loose and there are few defects during use.

According to the third aspect, since the core chain is preliminarily shaped, it is possible to obtain a core chain having a desired cross-sectional shape, and as a result, the appearance is similar to that of the core chain. It is possible to obtain a cored necklace with a desired design.
