Description

  The present invention relates to a structure for attaching a jewelry such as a diamond or a ruby to an accessory such as a pendant or a ring. In particular, the present invention relates to a structure that increases the apparent impression of jewelry attached to jewelry.

An invention for making a jewelry attached to an accessory appear large has been proposed.
For example, Patent Document 1 shows a large jewel by surrounding the outer periphery of the jewel with a glossy metal support with irregularities. As shown in Patent Document 2, this support is fixed with standing claws to form a ring, or as in Patent Document 3, it is embedded in a through hole of a member for jewelry and assembled into a pendant.

  However, in Patent Document 1, since the jewel is fixed with the locking claws of the support body, when processing the decorative irregularities on the support body, nerves are used in the work so that the cutting tool does not interfere with the locking claws previously formed. There is a problem of having to.

Also, the method of fixing with the nail requires at least 3 to 5 nail per jewel, so if the number of jewels is one, the number of nail will be 3 to 3 The number of multiples of 5 increases rapidly, and the fixing process of bending up the nail becomes complicated, and the method of embedding in the through holes is limited because there is a limit to packing between the through holes when there are multiple through holes. There is a problem that it is difficult to arrange jewels.

These problems are the problems to be solved by the present invention.
That is, an object of the present invention is to fix a jewelry simply and accurately on a metal decorative frame for emphasizing and magnifying the shine of the jewelry, and to accurately and accurately position the decorative frame with respect to the jewelry mounting base of the jewelry. It is to fix securely.

In order to solve the above-mentioned problems and achieve the object of the invention, the invention according to claim 1 is characterized in that a plurality of ridges are radially formed on the upper end surface of the metal decorative frame, and at least some of the ridges are formed. By deforming one end of the jewel toward the inside of the decorative frame, the jewel fitted in the recessed portion inside the decorative frame is integrally fixed to the decorative frame. A decorative pin is erected on the jewelry mounting base of the accessory, and the decorative frame is positioned by the decorative pin to fix the decorative frame to the jewelry mounting base.
A second aspect of the present invention is the configuration of the first aspect, wherein a plurality of decorative pins are erected,
A decorative frame in which the jewel is fixed is inserted between the decorative pin and the decorative pin is positioned by the decorative pin.
According to a third aspect of the present invention, in the configuration of the first aspect, the protrusion is formed by diamond cutting.
According to a fourth aspect of the present invention, in the configuration of the first aspect, a through hole is formed in each of the bottom portion of the recessed portion and the jewelry mounting base, and these through holes are communicated.
According to a fifth aspect of the present invention, in the configuration of the first aspect, a through hole is formed in the jewelry mounting base, and the inner peripheral surface of the through hole and the bottom surface of the decorative frame are laser-welded, whereby the decorative frame and the jewelry are provided. The mounting base is fixed.
The invention described in claim 6 is characterized in that, in the configuration of claim 1, the decorative frame and the jewelry mounting base are fixed by brazing the decorative frame to the jewelry mounting base.

According to the first aspect of the present invention, a jewel is fitted inside a metal decorative frame, and a large number of ridges are radially formed on the upper end surface of the decorative frame surrounding the outer periphery of the jewel. ) And the shine of the jewel are all united, giving the viewer the impression that the diameter of the jewel has expanded to the size of the outer edge of the decorative frame.
In addition, since the jewel is fixed by deforming one end of the ridge toward the inside, there is no need to separately provide a fixing means such as a conventional locking claw, so that a decorative frame can be easily manufactured. Since the bottom surface of the decorative frame is fixed to the jewelry mount with the decorative pin, the bottom surface is fixed. As a result, there is an effect that the jewelry can be assembled accurately and easily at the correct position.

In the second aspect of the present invention, a plurality of decorative pins are erected, a decorative frame in which the jewel is fixed is inserted between the decorative pins and the decorative pins, and the decorative frame is positioned by the decorative pins. Therefore, positioning is simple and reliable.
In the invention described in claim 3, since the protrusion is formed by diamond cutting, a facet rich in gloss can be obtained, and the jewel can shine even more greatly.

  According to the fourth aspect of the present invention, through holes are formed in the bottom of the recessed portion and the jewelry mounting base, and these through holes are communicated, so that external light can be taken into the gem through both through holes.

  In the invention of claim 5, since the decorative frame and the jewelry mounting base are fixed, the inner peripheral surface of the through hole of the jewelry mounting base and the bottom surface of the decorative frame are laser-welded, so that the welding trace is invisible. Does not spoil the beauty.

  In the invention described in claim 6, since the decorative frame is brazed to the jewelry mounting base to fix the decorative frame and the jewelry mounting base, even if there is a gap between the bottom surface of the decorative frame and the jewelry mounting base. It can be fixed by brazing the sides of the decorative frame. Therefore, there is an effect that the degree of freedom of design increases without being limited by the shape of the jewelry mounting base.

Embodiments of the present invention will be described.
In FIGS. 1 and 2, reference numeral 1 denotes a polished stone or gemstone subjected to faceting processing such as a brilliant cut, which is usually a diamond, but may be a colored stone such as ruby or sapphire.
Reference numeral 2 denotes a metal decorative frame. As the type of metal, when the diamond is the other party, the same white white gold as the combination is suitable. Depending on the color of the gem, use precious metals such as yellow gold, pink gold, or platinum.
The material shape of the decorative frame 2 is a cylindrical body, and the inner shape of the decorative frame 2 is a circle, an ellipse, or a square in accordance with the outer shape of the jewel 1.
By pressing, casting, or forging the cylindrical body, the annular upper end surface 3 is formed into a conical shape having the same center line as that of the cylindrical body, thereby forming an inclined surface that is gently inclined downward toward the outside. Instead of a cylindrical body, a line may be cut and processed into a similar shape.
In addition, as shown to FIGS. 5-8, it shape | molds in the funnel shape contrary to a cone shape, and you may make this upper end surface 3 into the inclined surface which inclined gently and low toward the inner side of the cylindrical body. In any case, when the upper end surface 3 is an inclined surface, there is an effect that the feeling of unity between the jewel and the decorative frame is increased by being familiar with the crown of the jewel.

Next, the upper end surface 3 is cut by a diamond cutting machine (not shown), and the upper end surface is subjected to mirror faceting. The facet processing is performed from the center toward the outer periphery or from the outer periphery toward the center so as to be radial from the center line of the annular upper end surface. The cutting depth is set so that all or part of the depth is shallower toward the inside of the upper end surface and deeper toward the outside. As a result, facets can be created from various angles, and the apparent size of the gem can be increased.
FIG. 9 is an enlarged plan view of the upper end surface 3.
As is clear from this, the facet processing completes a large number of radial ridges 4 extending outward from the center on the upper end surface. The number of protrusions depends on the size of the decorative frame, but is preferably at least 3 and at most 16. If the number of ridges is too large, the height of the ridges will eventually be insufficient, and the reflection efficiency will decrease. In the illustrated example, the number of the protrusions 4 is eight.
12 to 14 show the shapes of the end faces developed along the lines AA, BB, and CC in FIG. 11, respectively.
It can be understood from FIG. 12 that eight vertices of the protrusion 4 appear on the inner periphery of the annular upper end surface. Valleys 5 are cut into the roof-shaped slopes that form these ridges 4, thereby creating facets in a multifaceted manner. The number of the valleys 5 is a multiple of the protrusion 4, that is, 16 in the illustrated example.
When the ridge 4 is completed, the inside of the cylindrical body is adjusted to the size of the jewel, and the dish is precisely grinded to form the recessed portion 6, thereby completing the decorative frame 7.

Next, the jewel 1 is fitted into the recessed portion 6. At this time, the position of the jewel 1 and the ridge 4 is stopped in a state where the girdle (edge) of the jewel 1 hits the taper 8 provided inside the recessed portion 6. The relationship requires that the girdle of the jewel 1 is lower than the apex P of the ridge 4 looking into the recessed portion 6.
Further, when the jewel 1 is fitted, the height of the crown (upper surface) of the jewel 1 is preferably the same as or slightly higher than the upper end surface of the decorative frame 2. 3 and 4 and FIGS. 7 and 8 show another example of the recessed portion. In these examples, the step portion 9 receives the pavilion instead of the taper 8 to prevent excessive sunk of the jewel 1.

Next, as shown in FIG. 15, the apex P of the ridge 4 is carved with a chisel T (鏨) from the position just outside, and a nail is set up on the apex P, and the nail is bent inward ( 16), the top portion of the protrusion 4 is put on the girdle, and the jewel 1 is fixed inside the recessed portion 6. There are at least two places where the nails are covered, and four places in the example of FIG.
Although the recessed part 6 of FIGS. 1-8 has the through-hole 10 in the bottom part, it may have a bottom without providing a through-hole.

Next, the decorative frame 7 is fixed to the jewelry mounting base 11 of the accessory. Before that, a plurality of decorative pins 12 are erected on the jewelry mounting base 11. The decorative pin 12 is formed integrally with the jewelry mounting base 11 using a mold. In the example of FIGS. 17-21, the number of the decoration pins 12 is 8, the height is higher than the decoration frame 7, and the head is formed in a hemispherical shape. Reference numeral 13 denotes a through-hole whose aperture is smaller than the outer diameter of the decorative frame 7. In the example of these drawings, the number of through holes 13 is three.
Then, the decorative frame 7 with the jewel 1 is inserted between the decorative pin 12 and the decorative pin 12, the decorative frame 7 is positioned by the decorative pin 12, and the bottom of the decorative frame 7 is placed on the jewel. It is fixed to the mounting base 11.
In this state, the decoration pin 12 is in contact with the outer periphery of the decoration frame 7, and the head higher than the decoration frame 7 shines, giving the impression that the decoration pin 12 locks the jewel 1.
There are laser welding and brazing as methods for fixing the decorative frame. In laser welding, the inner circumference of the through hole 13 on the jewel mounting base side and the bottom surface of the decorative frame 7 are spot-welded, so that the welding mark is hardly visible. Reference numeral 14 in FIG. 20 indicates a welding mark of laser welding.
In the case of brazing, since the bottom surface of the decorative frame 7 and the top surface of the jewelry mounting base 11 are bonded, it is preferable to reduce or eliminate the through hole 13 on the jewelry mounting base side from the viewpoint of securing the bonding area. It is also possible to braze the side surface of the decorative frame 7 to the decorative pin 7 or the like.
The through hole 10 of the decorative frame 7 and the through hole 13 of the jewelry mounting base 11 have a common center. Thereby, the light can be taken into the jewel 1 through both through holes.
In this way, the jewel 1 is set on the jewel mount 11 through the decorative frame 7, and this is used to form a ring as shown in FIG. 24 or a pendant as shown in FIG.

The decoration pin 12 may be disposed relative to the diameter direction of the decoration frame 7 as shown in FIG.
FIGS. 26 and 27 show another example of a pendant. One decorative frame 7 is fixed to the jewelry mounting base 11. In this example, the decoration pin 12 is one, the decoration frame 7 is positioned between the groove 11a of the jewelry mounting table 11 facing the decoration pin 12, and the bottom surface thereof is fixed to the jewelry mounting table 11 by brazing. Reference numeral 15 denotes a hole through which the chain passes.
28 and 29 show another example of a ring, and the number of decoration pins 12 is six. The six decorative pins 12 are arranged so as to surround the outer periphery of one decorative frame 7 to position the decorative frame 7.
30 to 32 show still another example of a ring, in which a decorative frame 12 is attached to the center of four decorative pins 12 rising from a ring main body. The bottom surface of the decorative frame 12 is fixed on a ring-shaped jewel mounting base 11 that connects the four decorative pins 12 to each other. The fixing method is brazing with laser welding. The decorative pin in this example is not a columnar shape but a flat plate shape, and is in surface contact with the outer periphery of the decorative frame 12, so that positioning is more reliable and the decorative frame 12 can be stably supported.
In the above embodiment, the decorative pin only positions the decorative frame and contributes little to fixing, but the tip of the decorative pin is deformed inward and the conventional nail fixes the jewelry, A decorative frame may be fixed. In that case, of course, brazing and welding are unnecessary.
