Abstract

PURPOSE:To stabilize stone holding quality and plating quality and to make it possible to perform stone holding in a short time, by engaging a completed unitary stone holding clamp with a noble-stone/precious-stone fixing part through an elastic member for the noble stone/precious stone. CONSTITUTION:A noble stone/precious stone 4 to be held is mounted on an elastic member 5. The elastic member 5 is mounted on a noble-stone/precious- stone fixing part 2, which is located at a part of a stone holding base part 1. A completed stone holding unitary clamp 3 is placed on the upper part of the stone and engaged with the noble-stone/precious-stone fixing part 2 and an engaging part 6. Thus the clamp 3 is fixed. In this way, the noble stone/ previous stone 4 is neither shaken nor cracked. The stone is held with the elastic member 5 and the stone holding unitary clamp 3 with suitable pressure and can be fixed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for setting precious stones and jewels in watches, jewelry, etc.

[Summary of the invention]

This invention is designed to fix precious stones and jewels in stone fixing work by sandwiching them between a ready-made integrated stone fixing claw and an elastic member that engages with a part of the fixing part.

[Conventional technology]

Conventionally, as shown in Fig. 2, stone setting work involves setting a precious stone/jewelry 4 in the state 3c before crushing, which is a part of the integrated claw 3 for stone setting, and then setting it in the state 3b after crushing by hand or press processing. A method of fixing the stone in the state was known.

[Problem that the invention seeks to solve]

However, in the conventional stone fastening method, the stone fastening integral nail 3 is attached to a precious stone.
After the jewelry is set, it is deformed and fixed by external force, so advanced technology is required to fix the precious stones and jewelry with the appropriate pressure, which can cause the precious stones and jewelry to wobble or even break. It was easy to cause problems such as

Furthermore, regarding the precious metal plating on the stone retaining claw, if the plating is applied before the stone is set, the quality of the plating may deteriorate due to deformation of the claw after plating, and if the plating is applied after the right set, the precious metal or There were drawbacks such as insufficient plating at the contact point between the jewel and the nail, which often caused rust while being carried, and if plating was done before and after setting the stone, the manufacturing cost would be high.

Therefore, in order to solve these conventional drawbacks, this invention aims to make it possible to set precious stones and jewels in a state that does not shake and is difficult to break, in a short amount of time, without the need to deform the stone setting claw. .

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention has been proposed to attach a precious stone/jewel to a stone fixing base via a soft member in which a complete stone fixing integral claw including pre-formed plating is installed in a cushion-like manner under the precious stone/jewel. I made it consistent with .

[Effect]

For precious stones and jewels that are to be set as described above,
The soft material acts as an appropriate cushioning material, preventing rattling or deformation cracking due to high pressure, and the integrated stone retaining claw of the completed product reduces plating time and stabilizes plating quality. It can be done.

〔Example〕 Embodiments of the present invention will be described below based on the drawings.

In FIG. 1, a precious stone/jewelry 4 to be set is placed on an elastic member 5 which is placed on top of a precious stone/jewelry fixing part 2 which is a part of a stone setting base 1, and then the completed stone setting A sectional view showing a state in which the integral claw 3 is covered from above and the precious stone/jewelry fixing 2 and the retaining portion 6 are engaged and fixed.

In Figure 3, the stone setting procedure is the same as in Figure 1, but
An embodiment is shown in which the engaging part 6 between the stone-clamping integral claw 3 and the precious stone/jewelry fixing part 2 is dug into a part of the stone-clamping base l to reduce the overall height.

4 to 6, the stone fixing procedure is the same, but the shape of the stone fixing integral nail 3 is flanged, and the position of the engaging part 6 is set at the place of the precious stone/jewelry fixing part 2. A group of embodiments is shown in which the overall height is reduced by digging into the fastening base 1.

In the embodiments described above, the precious stone/jewelry 4 is sandwiched and fixed between the elastic member 5 and the integral pawl for stone fixing with appropriate pressure to prevent it from rattling or cracking.

Therefore, if the surface of the stone retaining integral nail 3 is left as a finished product until the plating process, the plating quality will not deteriorate and the plating can be done with fewer man-hours.

〔Effect of the invention〕

As explained above, this invention stabilizes the stone setting quality and plating quality by using an elastic member to mediate the precious stone/jewelry and engaging the completed stone/jewelry fixing part with the completed stone/jewelry fixing claw. This has the effect of making it possible to set stones in a short amount of time.
