Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jewelry pedestal, and more particularly to a jewelry pedestal such as a pendant, an earring, a cows button, or a titacks, in which light is applied to a back surface of the jewel.

[0002]

2. Description of the Related Art The present applicant has proposed a configuration in which a jewel decoration table whose annular part has been cut in 1994 can easily insert a jewel into the cut part. Of a jewelry decoration table consisting of: (Patent No. 2665311).

[0003] However, the above-mentioned patent invention forms a hole adjacent to two opposing surfaces cut in an annular shape and is orthogonal to the cut surface. However, it is not preferable to have a "hole" that functions only to insert a jewel, even if it is functionally useful, that is, a hole that is caused only by a function. Decorated ones are preferred.

The present invention has been made in view of such a situation, and is useful for a jewelry decoration table in which jewels are sandwiched between two opposing cut surfaces, and furthermore, after inserting the jewels, the aesthetic appearance is impaired. It is still another object of the present invention to provide a jewelry decoration table that contributes to making the jewel glitter.

[0005]

The jewelry pedestal according to the present invention is obtained by cutting a part of a ring-shaped jewelry pedestal, and cutting the ring on two opposing surfaces separated by the cut portion. In a jewelry decoration table in which a jewel locking groove is formed so as to hold the jewel so that the surface of the jewel faces in a viewable direction, the two faces of the jewel on the back side of the jewel in the jewel locking groove are provided. In order to transmit light to the back side, a recessed portion is provided on the opposite side of the two sides and on the back side of the jewelry table.

However, when the jewelry pedestal configured as described above is inserted into the jewel locking groove formed on the two opposing surfaces, the jewelry pedestal according to the above-described patented invention has the following features. The jewel can be easily inserted into the recess by using a tool as shown in FIG. 9 and light can be given to the jewel from the back of the jewel, so that the jewel shines brilliantly. In particular, when the gem is so-called "Brillian cut" on the back surface like a diamond and the back surface is illuminated, the gem is most suitable as a jewel jewelry decoration table in which the "glitteriness" is remarkably increased. In the case where the concave portion is designed to be a part of the unevenness of the surface shape of the jewel decoration table, the concave portion does not impair the design. In addition, jewelry decoration stands are "front and back" like pendants, earrings, cow buttons, tie tacks, etc.
In the case where is present, it is possible to make it completely inconspicuous by forming the concave portion on the back surface side.

[0007] If the concave portion of the jewelry decoration stand is a concave portion having a cross section expanded on the back surface side of the jewelry decoration table, light can be more effectively applied to the back surface of the jewelry decoration plate.

The recess of the jewel decoration stand is a recess having a cross section gradually expanding toward the back side of the jewel decoration stand, and a part of the recess is substantially parallel to the two opposing surfaces. However, in the case where they are provided facing each other as a part of each concave portion, the most suitable embodiment is achieved in that the jewel can be made to shine most effectively.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a jewelry decoration stand according to the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of the jewelry decoration table according to the first embodiment of the present invention as viewed obliquely from above, and FIG. 2 is a rear view as viewed from the opposite side to FIG.

A jewel decoration table A shown in FIG. 1 is a jewel decoration table for a pendant, and the entire shape of the jewel decoration table A has a form in which "a part of an annular shape is cut". On the two opposing surfaces 1A and 1B separated by the cutting, a jewel locking groove 2 (see FIG. 3) for locking a diamond D indicated by a two-dot chain line that has been “brilliant cut” is respectively provided. They are formed to face each other. Then, as shown in FIG. 3, only one of the two surfaces 1A and 1B is enlarged and shown in the figure, a portion on the back surface side of the jewel locking groove 2 of each of the two opposite surfaces 1A and 1B. Is the opposite surface 1
A concave portion (groove) 3 is formed on the A, 1B side and on the back surface 11 side of the jewel decoration table A. As shown in FIG.
It is a concave portion whose cross section gradually expands from the back surface 11 side of the jewel decoration table A, that is, from the diamond D to the back surface 11 side. Further, the connecting portion of the concave portion 3 with the back surface 11 is rounded (squared) so that the corner is not caught and for aesthetic treatment.

According to the jewel decoration table A thus configured, the following operation is achieved. First, when the diamond D (jewel) is sandwiched in the jewel locking groove 2 of the jewel decoration table A, the tip of each of the opposing two surfaces 1A and 1B is indicated by a two-dot chain line in FIG. Only one part is illustrated, and one end 20a of the tool 20 illustrated in FIG. 9 is inserted and locked, and the two opposing surfaces 1A and 1B of the jewelry decoration table A are spread apart from each other, and the diamond D is inserted therebetween. I do. Then, the edge d of the diamond D is
The tip of the tool is retracted while being locked in the jewel locking grooves 2 of A and 1B. By this operation, the attachment of the diamond D (jewel) to the jewel decoration table A is completed. Then, the diamond D mounted in this manner is a pendant, and the back surface D1 of the diamond D is hung on the chest as a pendant.
Since the light is sent from the space formed by the concave portion 3, a shine which is not present in the conventional jewelry decoration table is generated. Further, even if the back surface 11 faces outward when the concave portion 3 is used as a pendant, the concave portion 3 can be seen as a part of the design because of the round processing and the like, and the overall design can be reduced. Almost no loss.
Further, as shown in FIG.
If it is formed as one concave portion 103 that constitutes a part of the uneven shape of the design of the jewelry decoration table A, even if the back surface faces outward when used as a pendant,
It doesn't hurt the design at all. Further, the concave portion 3
As the concave portion 103, if the light is sent to the back surface of the jewel, as viewed from the back surface, FIG.
Any shape as shown in (d) may be used.

By the way, instead of the concave portion 3 shown in FIG. 4B, the concave portion viewed from a direction perpendicular to the cut surface of the concave portion 3 in FIG. The recess 203 may have a cross section as shown in FIG. That is, as shown in the cross-sectional view of FIG. 6A, a surface 203 a in which the concave portion 203 is substantially parallel to two opposing surfaces formed by cutting the ring is straight as a part of each concave portion. The recesses 203A may be formed so that the surfaces face each other, or FIG.
As shown in FIG. 2, the concave portion 203 is formed by cutting an annular shape.
Even in the case of 03B, as shown in FIG. 6 (c), the recess 203 is provided with a stepped portion 203b at a part of the surface side of the surface 203a of the recess so that the tip of the tool can be easily locked. The concave portion 203C may be used.

The present invention as described above can be used not only for a pendant as shown in FIGS. 7 to 9 but also for a jewelry stand such as an earring, a cows button, and a titac (not shown). It can be adopted and has the same operation and effect as the above-described case.

[0014]

According to the jewelry decoration table according to the present invention, it is possible to easily perform a case where a jewel is sandwiched between two opposing cut surfaces. It does not impair the appearance, and also contributes to the improvement of "glitter" that is most required as a jewel.
