By attaching jewelry such as diamonds to the fasteners of this kind of chain jewelry as a decorative means. The provision of fasteners that further enhance decorative functions such as neckless, bracelet, and anklet.

[0002]

[Prior art]

 Generally, necklaces, bracelets, anklets, and other chain jewelry made of alloys such as gold, silver, and platinum group metals are used as fasteners for connecting chain jewelry. A fastener made of a corresponding material is often used, and the fastener tends to be relatively small in size corresponding to the chain-like accessory to be connected.

Therefore, this type of fastener is often relatively simple in construction, and looks good in spite of the fact that expensive materials such as gold alloy, silver alloy, and group C metal alloy are used. In general, necklaces, bracelets, anklets, and other chain-shaped accessories that can be conveniently connected to each other or have a structure suitable for sure connection are sufficient. There was a tendency to focus on the composition.

[0004]

[Problems to be solved by the device]

 However, the fasteners used as connecting means for chain jewelry such as necklaces, bracelets, and anklets of this kind have a feeling of strangeness in chain jewelry constructed as a continuous shape based on a series of motifs. Although it is a small object and is relatively simple in structure, it is easily noticeable, and it has a relatively large presence in chain jewelry such as necklaces, bracelets, and anklets. Therefore, the unique decoration created by chain jewelry There was a risk of impairing the function.

From this point of view, the necklace, bracelet, anklet and the like, which is used as a connecting means for chained jewelry, is configured so that the fastener itself has a shape similar to that of the chained jewelry to be connected. Attempts have been made to ensure that the peculiar decorative properties of chain jewelry such as shoes, bracelets, and anklets are not interrupted in the middle, but such decorative properties similar to chain jewelry are used as fasteners. There is a natural limit to what can be obtained, and there are inconveniences such as a significant loss in the function of the fastener and a significantly complicated operation of attaching and detaching the fastener.

From this point of view, the present invention leaves the function of the fastener as it is without modifying the structure of the fastener itself, and further, the decorative function of the chain-like accessory as the decorative means. We tried to attach jewelry such as diamonds and jade to the fasteners as a means to further enhance the decorative effect of the chain jewelry without any damage.

[0007] However, with this type of fastener, the engagement and disengagement operation of the fasteners is relatively frequently performed, and the engagement and disengagement operation of the fasteners is performed in a groping state. When jewelry is attached as a decoration means to the fastener, the surface of the fastener or the surface of the chain-like accessory is damaged by the operation of engaging and disengaging the fastener. there were.

Further, the engaging and disengaging operation of such a fastener is often relatively violent in the state of groping, and jewelry attached to the fastener is engaged and disengaged with the fastener. In many cases, there were inconveniences such as cracking, chipping, or falling out of fasteners associated with dismantling.

The present invention has an excellent decorative effect in view of the inconvenience of fasteners used as connecting means for chain-like accessories such as necklaces, bracelets, and anklets in the related art, and moreover, chains of necklaces, bracelets, anklets, etc. The purpose of the present invention is to provide a fastener that does not cause scratches or the like on the clothing accessories or fasteners and at the same time does not damage or damage the jewelry to be assembled.

[0010]
