Description

  The present invention relates to a jewelry and a manufacturing method thereof, and more particularly to a jewelry such as an eternity ring in which a plurality of jewels are continuously arranged in parallel on the outer surface of a jewelry base and a manufacturing method thereof.

  Various methods for applying a pattern to the surface of a jewelry have been proposed in the past, and a technique for applying a pattern by a diamond cutting method or a press engraving method is widely used as in Patent Document 1 and has a smooth outer peripheral surface. It is known that a sparkling decoration can be obtained compared to

  As a technique for making the shine of gemstones more shining, a technique in which lights and LEDs are arranged under the jewels as proposed in Patent Document 2 has been proposed. is not.

Further, Patent Document 3 proposes a method in which a valley is formed on the outer peripheral surface of a ring and decoration such as diamond cutting is applied along the valley line, but the technique is a surface of a complicated shape such as a cast product. It is a means for processing, not a technique for efficiently shining cut rings and gemstones.
Some of these references place gems on the cut surface, but the way to fasten the jewels is the conventional way of making a hole in the cut surface and fitting the jewels tightly on the pedestal. It was inferior.

  In terms of the shine of gemstones, standing nail rings are generally used to bring out more brilliance, but the standing nail part protrudes from the ring surface, and the strength of the metal of the standing nail part is Necessary, too soft or hard even brittle materials can not be used, there are restrictions on the selection of bullion, and there is a problem in terms of cost when cutting with a cut ring as in Patent Document 4 .

Furthermore, Patent Document 5 and others have specially cut the lower part of the gemstone. However, since the gemstone is cut, the number of carats is reduced and the lower part of the gemstone is covered with metal. It was not so effective in terms.
JP 2006-230632 A Japanese Unexamined Patent Publication No. 55-110503 JP-A-5-269011 JP-A-8-182517 Japanese Patent Laid-Open No. 8-24016

  In addition, there is the engraving technique as one of the stone-holding methods, but in general, the dish is processed, the jewel is dropped into the place where the stone seat is provided, the bullion is brought in, and the crown part is locked. Therefore, the girdle part, which is the maximum diameter of the jewelry, will be lowered by one step from the jewelry base surface, and there will be a slight shadow due to the wall of the jewelry base that has been lowered one step. The lower part of the jewel is in close contact with the metal, so the light reflectivity to the jewel is poor and the shine of the jewel is impaired.

  In another stone retaining method, a stone seat with claws is provided, and the crown of the gemstone is locked with several claws without dropping the gemstone into the dished hole, while maintaining the diameter of the gemstone effectively. Although there is a technique related to the above-mentioned standing nail etc., it is generally processed by a cast technique, so it is difficult to obtain a mirror surface on the stone seat, and if the surface of the stone seat is dirty, the original brightness of the gem is impaired. There was a problem.

  Another technique for shining other jewelry is to sculpt the bullion around the jewels with a chisel to obtain a shiny luster. However, this technique requires skilled technology, and since it becomes processing one by one, it becomes expensive in terms of cost, and it is difficult to obtain a uniform mirror surface for the surface processed by the chisel, Because it can only be processed to the extent that it cuts the surface, it was not possible to obtain the brilliance of incident light from below the gemstone.

  In an accessory such as an eternity ring in which a plurality of gemstones are continuously arranged in parallel on the outer surface of the jewelry base, the gemstones can be made to shine, the gemstones appear larger, and any bullion material can be used at low cost. It is an object of the present invention to obtain an accessory and a manufacturing method thereof, and proposes means for solving such a problem.

In order to solve the above-mentioned problems, the present invention has completed the present invention by, for example, performing polyhedron cut on the continuous groove on the outer surface of the accessory base and forming a gap between the gem and the polyhedron cut surface. .
That is, the present invention
“1. A jewelry device in which a continuous groove is provided on an outer surface of a jewelry base, and a plurality of jewels are arranged in parallel in the continuous groove, and the continuous groove has a polyhedral cut, and a lower part of the jewel There is a space between the surface subjected to the polyhedral cut and the accessory.
2. When the jewelry is locked to the jewelry base, the width of the continuous groove is locked by plastic deformation at several places so that at least a part of the end of the maximum diameter of the jewelry is exposed on the continuous groove. The jewelry according to Item 1.
3. The accessory according to any one of items 1 and 2, wherein side walls are provided at both ends of the continuous groove provided in the accessory base.
4). The outer surface of the jewelry base is provided with a continuous groove with polyhedron cut, and after the dish is processed to provide a stone seat as needed to place a plurality of gems in the continuous groove, the lower part of the gem and the polyhedron cut The width portion of the continuous groove is locked by being plastically deformed at several places so that at least a part of the end of the largest diameter of the gem is exposed on the continuous groove so as to have a gap between the surface and the surface subjected to The manufacturing method of the jewelry according to any one of Items 1 to 3.
5. The method for manufacturing an accessory according to claim 4, wherein the polyhedron cut of the continuous groove is performed by a diamond cutting method. ".

With the above configuration, since the metal surface under the jewel is a mirror surface of a polyhedral cut surface, incident light transmitted through the jewel can be diffusely reflected, making the jewel more shining, Since it is open and incident light can enter under the jewel without passing through the jewel, the jewel can be made to shine more with light from under the jewel.
In addition, the entire outer periphery of the jewel is buried by fastening the jewel in the width of the continuous groove so that at least a part of the end portion such as the so-called girdle portion having the largest outer periphery of the jewel is exposed on the continuous groove. And can make the jewel appear larger.
In addition, since the parts without jewels are cut into polyhedrons, the bullion itself has a sparkle, increasing the value of jewelry as a whole.
Moreover, since it can reduce in weight by providing a continuous groove | channel, even if it is a case where an expensive material is used, it can provide at a reduced price.
In addition, since it has a simple form, there are many excellent effects such as being able to obtain the jewelry at a low cost without selecting a raw material of the metal.

There are various accessories such as pierced earrings, earrings, pendants, and bracelets in addition to rings as jewelry that continuously arranges a plurality of jewels in parallel on the outer surface of the base, but in the present invention, mainly the ring base A description will be given using an eternity ring (hereinafter simply referred to as an eternity ring) in which a plurality of jewels are continuously arranged in parallel on the outer surface.
There are two types of eternity rings: full eternity where stones such as diamonds are stoned all around the ring, and half eternity where stones are stoned halfway.
When stones are stoned all around like full eternity, it is necessary to stone stones at equal intervals, so there are generally many rings provided with stone seats for fastening gemstones by casting techniques.
However, when full eternity is cast, it is necessary to produce a prototype for each size, which is expensive.

Half-eternity can be resized, so the number of prototypes is small, but the product value is inferior to full-eternity.
In addition, as described above, the stone seat formed by the casting technique has a rough finish due to the characteristics of its manufacturing method, and it is difficult to mirror such a stone seat with a complicated shape. If the surface is rough, there is a problem that the light reflectance to the jewel is deteriorated and the shine of the jewel is impaired.
As described above, the present invention cannot be used for an accessory obtained by a casting technique, but can be said to be a technique mainly used for an accessory obtained by machining such as a cut ring.

  The basic configuration of the present invention is an accessory in which a continuous groove is provided on the outer surface of a jewelry base, and a plurality of jewels are arranged in parallel in the continuous groove, and the continuous groove is subjected to polyhedral cutting, and It is an accessory characterized by having a space | gap between the lower part of the said jewel, and the surface which gave the polyhedron cut.

The continuous groove (2) provided on the outer surface of the accessory base can be provided by cutting the outer surface (1) of the accessory base formed as shown in FIG. 2-A by a technique such as diamond cutting. Moreover, after forming a groove | channel, you may provide by mechanical processing, such as another engraving technique and press work.
At the same time as or after forming the continuous groove (2), a polyhedral cut is performed such as forming a striped pattern to form a polyhedral cut surface (3) having a mirror surface in the continuous groove (2). It is more preferable if it is a diamond cutting method in which the polyhedral cut surface (3) can be formed simultaneously when forming the continuous groove (2).
Further, it is more preferable that the continuous groove (2) provided on the outer surface (1) of the jewelry base is a continuous groove along the axial direction because it can be easily formed by a diamond cutting method.
The continuous groove (2) may be a part of the accessory, or may be provided on the entire surface by arranging a plurality of rows. For example, when it is used for a ring, the entire circumference may be used, or a continuous groove that forms a part of the circumference may be used if a plurality of jewels can be arranged together. (Fig. 3, Fig. 4)
Further, the polyhedral cut surface (3) may be the entire cutting surface as shown in FIG. 1-B, or when a continuous groove is formed in a square shape, it may be applied only to the bottom or on the wall surface, or discontinuous. (Not shown).

In the present invention, a plurality of jewels (4) are arranged in parallel in the continuous groove (2), but as shown in FIG. 1-D, between the polyhedral cut surface (3) and the jewel (4). Is configured to have a gap (5).
Depending on the shape of the continuous groove to be formed, it has a gap (5) between the lower part of the gemstone (4) and the polyhedral cut surface (3), such as the pavilion part in the brilliant cut. The transmitted incident light is scattered by the mirror-shaped polyhedral cut surface (3), and the light that becomes reflected light from multiple directions hits the lower part of the jewel (4), so that the shine of the jewel can be increased.
Further, as shown in FIG. 1-E, the portion (α) without the jewel (4) in the continuous groove (2) is open unlike (β) in FIG. 2-D, and the jewel without passing through the jewel. Since incident light can be put under (4), the jewel (4) can be made more shining with light from under the jewel (4).

  In the present invention, when the gemstone is locked to the base, the stone portion (7) is provided on the width portion (6) of the continuous groove (2), if desired, and then the stonestone (7) is provided. Plastic deformation called Nanako (8) in several places in the width portion (6) of the continuous groove (2) so that at least a part of the end portion (4-1) such as the girdle portion having the largest diameter is exposed on the continuous groove. And can be locked.

  As mentioned above, in the stone retaining by the engraving technique, the maximum diameter of the gemstone is generally obtained by dishing the stone, dropping the gemstone into the place where the stone seat is provided, and locking the crown portion with the metal The girdle part is one step down from the jewelry base surface, and there is a problem that the jewelry appears to be small due to a slight shadow caused by the wall of the jewelry base that has gone down one step. There is also a drawback in that the light reflectance to the jewel is deteriorated and the shine of the jewel is impaired.

In that respect, in the present invention, the portion of the continuous groove (2) opens the end portion (4-1) such as a jewel girdle portion, so the portion hidden in the metal can be minimized, You can make the jewel appear larger.
That is, the entire outer peripheral portion of the jewel (4) is buried by retaining a part of the end portion (4-1) such as a so-called girdle portion having the largest outer periphery of the jewel (4) in the width portion of the continuous groove. Without doubling the effect of making the gem appear larger.

  In the present invention, as described above, it can be used for full eternity for retaining gemstones such as diamond around the entire ring and half eternity for retaining stones in the semicircular position, etc., but is continuously provided on the outer peripheral surface of the ring base. When the groove (2) is employed in a ring having a circumferential continuous groove, it is more effective.

  In general, when there are a large number of gemstones used such as full eternity, gemstones with relatively small grains are often used, and the base becomes thin. However, in the case of a cast product or the like, there are many materials with relatively weak strength, and there is a problem in the commercial value, and the merit of using the present invention for cut accessories is increased.

  In this invention, it is good also as a structure which provides a side wall (9) in the circumferential both ends of the outer peripheral surface (1) of a jewelry base as further illustrated in each figure. This not only increases the decorative effect, but also protects the gemstone protruding from the outer peripheral surface, and prevents the gemstone (4) from dropping off.

Further, if the inner wall surface (9-1) is an inclined surface, the side wall (9) can be easily processed such as a groove and a stone wall, and it can hardly become a shadow that blocks incident light, so that the brightness can be increased.
Furthermore, if the inclined surface of the inner side surface is a mirror surface, the incident light on the jewel can be increased and the brightness can be increased.
Further, it is more preferable to make polyhedral cuts on the surface of the side wall (9) and the inclined surface, since the brightness can be further increased and the value as an accessory can be increased.

  Any jewels (4) used in the present invention can be used as long as they have shine, and the cutting method is not only facet cut such as brilliant cut and emerald cut, but also any processing method such as cabochon cut. Can be adopted. Among them, a gem having high glitter such as diamond is preferably used, and a shape having a lower bulged cone portion such as a brilliant cut which also performs a glitter cut on the lower portion of the gem as shown in the drawing is preferable because the effect of the present invention is increased. .

  Moreover, as shown to FIG. 1-D, the communicating hole (10) can be provided in the bottom part of a continuous groove | channel (2), and also the incident light with respect to jewelry can be increased. This can increase the brightness.

  Moreover, although the continuous groove | channel by one circular arc was shown as continuous groove | channel (2) in this invention, it is good also as a circular arc from which a some diameter differs, and it is also possible to set it as grooves other than a circular arc (V groove, flat groove, etc.). Yes (not shown).

Hereinafter, examples of the present invention will be described by taking an eternity ring as an example and a manufacturing method thereof, but the present invention is not limited thereto.
Example Using a material of Pt900, a ring having a ring base with side walls formed at both ends as shown in FIG. 1-A was formed by plastic working / cutting. In the figure, the ring is sectioned and a part of the outer peripheral portion thereof is shown (FIGS. 1 and 2).
Thereafter, an arc-shaped continuous groove (2) as shown in FIG. 1-B was formed on the outer peripheral surface (1) of the ring base in a full-circular shape while performing polyhedral cutting.
And after providing the communicating hole (10) as shown to FIG. 1-D in the location which corresponds to the jewelry arrangement | positioning position of a continuous groove | channel (2), the width | variety part (6) of a continuous groove | channel (2) is made into jewelry (4). In accordance with the shape, the dish is processed into a circular shape to form a stone seat (7). As shown in FIG. 1-D, the lower part of the brilliant-cut gemstone (4) and the polyhedral cut surface (3) The width portion (2) of the continuous groove (2) so that the girdle portion (4-1) having the maximum diameter of the jewel (4) is exposed at the portion on the continuous groove (2) so as to have a gap (5) between After adjoining 6), the width portion (6) was plastically deformed at four places called Nanako (8) to lock the crown portion of the jewel (4).
As shown in FIG. 1-E, the jewel (4) was provided with a constant interval between the jewels, and a plurality of jewels were arranged by the same method over the entire circumference. (Figure 3)
With the above means, a full eternity ring as an accessory of the present invention was completed.

  Other embodiments include a half-eternity ring (not shown) in which the gems are arranged over the entire circumference in the above embodiment, and a ring in which a plurality of gems are arranged for each block. Alternatively, it is possible to configure an eternity ring or the like in which a plurality of blocks are arranged about half a circle (FIG. 4).

3 is a single row, it is also possible to provide a plurality of continuous grooves and a plurality of rows of jewelry arrangements (FIG. 4).
In addition, the present invention can be applied to accessories such as earrings and earrings (not shown) as shown in FIG. 5 and pendants and bracelets (not shown) as shown in FIG.

Comparative Example 1
In the above embodiment, the continuous groove (2) is not provided, the same stone base (7 ′) as shown in FIG. 2 and the side wall (9) perpendicular to the base are provided, and the crown of the jewel (4) is engaged. A full eternity ring was completed in the same manner as in the example except that it was stopped.

Comparative Example 2
A full eternity ring was completed in the same manner as in the example except that the polyhedron cut was not applied to the continuous groove (2) in the above example.

As described above, since the jewelry obtained by the embodiment has a polyhedral cut surface (3) below the jewel (4), incident light transmitted through the jewel is irregularly reflected to make the jewel (4) brighter. In addition, the portion (α) of the continuous groove (2) without the jewel (4) is open, and incident light can enter under the jewel (4) without passing through the jewel. (4) The jewel (4) was able to shine more with the light from below.
Further, by holding the jewel (4) in the width of the continuous groove so that at least a part of the end (4-1) such as the largest girdle part on the outer periphery of the jewel (4) is exposed on the continuous groove, The jewel (4) could be shown larger without the entire outer periphery of the jewel (4) being buried.
Furthermore, since (α) where there is no jewel (4) is also cut into polyhedrons, the bullion itself has a sparkle, and the value of jewelry as a whole increases.

On the other hand, since the lower part of the jewelry (4) was covered with a metal base metal, the jewelry of Comparative Example 1 was darker and the jewels were less bright than the examples.
As for the accessory of Comparative Example 2, it was not possible to obtain a shine like that obtained by mirror finishing the continuous groove (2) with considerable efforts.
