Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gem stone retaining method in which a precious metal support is supported by a plurality of fulcrums holding the outer periphery of the gemstone from the outside. In addition, in this specification, the outer peripheral portion of the jewel means an outer peripheral portion formed in a convex shape in section facing outward in the handing direction of the jewel.

[0002]

2. Description of the Related Art As shown in FIG. 5, in a conventional stone retaining method for a jewel, the ridge 50 can be fitted to a support so that the ridge 50, which is the outer periphery of the jewel, can be sandwiched from the outside. Groove 5
1, 52 are formed. When the grooves 51 and 52 are provided, the length connecting the inner portions of the grooves 51 and 52 is set to be substantially equal to the transit length of the jewel, and the inner shape of the one groove 51 is set to the above. The V-shape is formed so as to abut the upper and lower cut surfaces 53, 54 near the peripheral edge 50, while the upper side is opened so that the inner shape of the other groove 52 abuts only the lower cut surface 54 near the peripheral edge 50. It is almost V-shaped. Then, while fitting the peripheral edge 50 into one groove 51, the peripheral edge 50 is also fitted into the other groove 52 from the open upper portion. Subsequently, the jaw 55 corresponding to the open portion is hit from the outside with a chisel 56 so that the inner shape of the other groove 52 is deformed so as to abut on the upper cut surface 53 near the peripheral edge 50 of the jewel. , It is common to fix.

Another conventional example is one in which various jewels are supported on a support base at three or more points (not shown). In the case of the two-point support type stone retaining method described above, Similarly, in each of the methods, an open jaw portion is formed on a predetermined support portion and is deformed by hitting it with a chisel or the like so as to abut the upper and lower cut surfaces near the peripheral edge of the jewel.

[0004]

In any of the above-mentioned conventional examples, in the processing work of hitting the jaw portion 55,
Since the ridge 50 of the jewel is hit while being fitted in the groove 52, the jaw portion 5 is formed on the upper cut surface 53 in the vicinity of the ridge 50.
5 The inner side hits and bounces, and is difficult to deform so as to be in close contact with the upper cut surface 53. Therefore, it is not possible to adopt it because not only are the gems wobble or fall off the support, but also if the gemstones are provided on the surface of the support because they are hit with the chisel 56, these gems may be damaged. There is a problem. Further, there is also a problem that this stone retaining work requires a skilled technique and the labor cost is high.

An object of the present invention is to solve the above problems, and an object of the present invention is to provide a gem stone retaining method that solves the problems.

[0006]

In order to achieve the above object, the present invention provides, for example, a U-shaped noble metal support base 2 having two leg-shaped portions 3 and 3, and the both leg-shaped portions 3 and 3 are provided. 3. A pair of grooves 7, 7 with which the peripheral edge 6 can be fitted is provided at the relative position of the inner surface. The inner portions 7a, 7a of the grooves 7, 7 are
The length (L) connecting the spaces is approximately the same as the crossover length of the peripheral edge 6 which is the outer peripheral portion of the jewel 1. Next, the peripheral edge 6 of the jewel 1 is fitted into the grooves 7 and 7 of the support base 2 and then stored.
After the brazing filler metals 8 and 8 melted by heating flow into the grooves 7 and 7, they are solidified by natural cooling or forced cooling.

[0007]

According to the above-mentioned stone retaining method, the brazing materials 8 and 8 which have been cooled and solidified are brought into contact with the upper and lower cut surfaces 4 and 5 in the vicinity of the peripheral edge 6 in close contact with each other. It is fixed firmly without wobbling to 2. In addition, in the processing step, the support base 2 heated by the brazing materials 8 and 8 expands, the interval between the leg portions 3 and 3 slightly expands, and the length connecting the grooves 7 and 7 increases. , Length (M). Therefore, between the inner surfaces of the grooves 7, 7 expanded by this expansion and the peripheral edge 6 of the jewel 1, the brazing materials 8, 8 are provided.
Will enter. After cooling, the support base 2
Contracts so that the legs 3, 3 clamp the jewel 1 from both sides.

FIG. 4 is a front view showing a leg portion and a jewel at the time of processing, the leg portion being cut in the width direction and being represented by an end face.

A gem stone-fixing process according to this embodiment will be described. (A) First step: precious metal support 2 on which jewelry 1 is attached
(Preferably 18K or Pt900) is formed into a substantially U shape having the leg portions 3 and 3. The jewel 1 has cut surfaces 4 and 5 on the upper and lower sides, and a peripheral edge 6 which is an outer peripheral portion of the jewel of the present invention is formed between the upper and lower cut surfaces 4 and 5. (B) Second step (FIG. 2): Both leg-shaped portions 3 of the support base 2.
Elliptical grooves 7 and 7 whose major axes face the same direction as the leg portions 3 and 3 are formed at predetermined positions on the inner surfaces facing each other. The cross-sectional shape of the grooves 7, 7 (the shape in which the leg-shaped portions 3, 3 are cut in the width direction) is from the inner portions 7a, 7a formed along the peripheral edge 6 of the jewel 1 to the elliptical periphery. It has a V-shape due to the slope extending to the bottom. Furthermore, the both inner parts 7
The length connecting a and 7a is set to be almost the same as the crossover length (L) of the peripheral edge 6 of the jewel 1. (C) Third step (FIG. 3): The jewel 1 is fitted into the grooves 7 and 7 with the peripheral edge 6 thereof oriented along the inner portions 7a and 7a. (D) Fourth step (FIG. 4): The brazing filler metals 8 and 8 which are heated (700 to 750 ° C.) and melted are introduced into the grooves 7 and 7 of the support base 2, respectively. The support base 2 slightly expands when heated by the melted brazing filler metal 8 and 8 so that both legs 3 and 3 are formed.
And the length connecting the inner portions 7a, 7a also increases to become the length (M). Therefore, the melted brazing filler metal 8, 8 enters the inner portions 7a, 7a of the grooves 3, 3 and the peripheral edge 6 of the jewel 1 and the gap in the vicinity thereof. Also, the brazing material 8,
8 is preferably made of the same material as the support base 2. (E) Fifth step: Supports 2 and 2 and brazing materials 8 and 8 are solidified by natural cooling. The brazing materials 8 and 8 solidify in a short time when they start to cool. In addition, the brazing materials 8 and 8 which are solidified due to the contraction of the support base 2 due to cooling are
Since the leg portions 3, 3 tend to contract while being inserted between the inner surface of 7 and the peripheral edge 6 of the jewel 1, the leg portions 3, 3 tighten the peripheral edge 6 from both sides. (F) Sixth step (FIG. 1): The chain 9 is attached to the curved portion of the support base 2 to complete the bracelet.

Next, the operation and effect of the above embodiment will be described. In the grooves 7 and 7, the solidified brazing materials 8 and 8 respectively abut on the upper and lower cut surfaces 4 and 5 in the vicinity of the peripheral ridge 6, so that the jewel 1 wobbles with respect to the support base 2. No, it is fixed securely.

It should be noted that the present invention is not limited to the above-mentioned embodiment. For example, a ring, etc., instead of a bracelet,
It may also be applied to other products that stone jewels. Further, the support base 2 may be changed to another shape having no leg portions 3 and 3, and the number of grooves may be changed to three or more. Further, in the fourth step, the support base 2 may be heated in advance, or the brazing material 8 may be made to flow into one groove 7 and not to the other.
In this case, the other groove 7 has a shape capable of abutting the outer shapes of the upper and lower cut surfaces 4 and 5 near the peripheral edge 6 of the jewel 1. In addition, in the above case having three or more grooves, the brazing material may not be flowed into all the grooves but may be allowed to flow into only a predetermined one. Furthermore, the jewel 1 may have any other shape without the peripheral ridge 6 as long as it has an outer peripheral portion formed in a convex cross-section facing outward in the delivery direction.

[0012]

As described above, according to the present invention, since the brazing filler metal which is cooled and solidified is brought into close contact with the vicinity of the outer periphery of the jewel,
The jewel has the effect that it does not wobble with respect to the support and is securely fixed.
