Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a gem support fixing structure for supporting and fixing a gem such as diamond, ruby, and sapphire to a gemstone table.

[0002]

[Prior art]

 As a structure for supporting and fixing a jewel to a jewel table, a structure for supporting and fixing a jewel using a nail, or a structure for providing a frame on a jewel table and embedding the jewel in the frame and fastening the frame is known.

[0005] FIG. 5 shows a conventional jewel support fixing structure, in which (a) is a cross-sectional view and (b) is a plan view, in which a plurality of stands are mounted on a frame 2 of a jewelry table 1 made of a precious metal such as gold, silver or platinum. A nail 3, such as a nail, a square nail, a today's nail, or a split nail, is provided, and the nail 3 is bent and latched on the upper surface of the jewel 4, and is supported and fixed.

In the conventional supporting and fixing method, when the jewel is viewed from above, the nail 3 or the frame 2 hides a part of the jewel on the surface and peripheral portion of the jewel 4, so that the entire jewel cannot be seen. Large and can't look beautiful. In addition, since the nail 3 is protruding, the nail 3 is deformed due to the nail 3 being caught on clothing or hitting an object, or the jewel 4 is dropped due to the deformation of the nail 3. Was.

[0005] Therefore, there has been proposed a support fixing structure for solving the above-mentioned drawback caused by the nail. FIG. 4 is a cross-sectional view of a conventional supporting and fixing structure in which the jewel table is not visible from above. The claw locking groove 6 is provided below the girdle 5 of the jewel 4, and the claw locking groove 6 The jewel 4 is supported and fixed by engaging the claws 3. According to this supporting and fixing structure, since the claw 3 is located below the girdle 5, the claw 3 may extend to the upper surface of the peripheral portion of the jewel 4 to hide a part of the jewel 4, as in the above-described supporting and fixing structure. Since there are no jewels, the jewels can be made to look large and beautiful, and the claws 3 do not get caught on clothing or hit objects.

[0006]

[Problems to be solved by the invention]

 However, the work of supporting and fixing the jewelry with the nails or the work of removing the jewelry is an operation that requires extremely skill. Also, when removing jewelry from the jewelry table to change the design of the jewelry table or exchange jewelry, it is difficult to remove the nail from the jewelry because the nails are made of metal, and also deform and remove the nails Therefore, if the nail is broken or deformed significantly, the jewelry table cannot be used again.

Accordingly, the present invention provides a jewel support fixing structure that makes the jewel look large and beautiful, securely fixes the jewel to the jewel table, and can easily attach and detach the jewel to and from the jewel table without skill. Is what you do.

[0008]

[Means for Solving the Problems]

 The jewel support and fixing structure of the present invention has a locking hole at the bottom of the girdle of the jewel, a through-hole through which a bar-shaped fixing tool penetrates at the top of the fixing frame of the jewelry table, and a rod-shaped fixing through the through-hole. The tool is characterized in that the tip of the tool is inserted into the locking hole, and the jewel is supported and fixed to the jewel table so that the upper end of the fixing frame is located below the girdle. Screws, pins or nails are used for the rod-shaped fixing tool.For screws, screws are formed in the through holes.For pins or nails, their rear ends are welded to the fixing frame to remove them. It is preferable to prevent it.

[0009] In addition to the above-described configuration, a locking projection provided on the fixing frame may be further engaged with a locking hole of the jewel.

In the present invention, precious stones such as diamond, ruby, sapphire, and emerald, semi-precious stones, and artificial or synthetic stones thereof are collectively referred to as jewels.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of a structure for supporting and fixing a jewel to a jewelry table according to the present invention, wherein FIG. 1 (a) is a sectional view and FIG. 1 (b) is a plan view. In the jewel 4, two or more locking holes 7 are formed at the lower part of the girdle 5 so as to face each other. In this embodiment, as shown in FIG. 1 (b), it is formed at four places. The locking hole 7 has a depth parallel to the girdle 5 and a depth at which a tip of a rod-like fixing tool such as a screw, a pin, or a nail described below enters to lock the jewel 4 and securely support and fix the jewel 4. I do. A locking groove may be used instead of the locking hole.

A through hole through which a rod-shaped fixing tool 8 penetrates in the upper part of the fixing frame 2 of the jewelry table 1 made of a precious metal such as gold, silver, platinum or the like in correspondence with the locking hole 7 provided in the lower part of the girdle 5. 9 is provided. As shown in FIG. 1A, when a screw is used for the rod-shaped fixture 8, a thread groove into which the screw 8 is screwed is formed on the inner surface of the through hole 9. It is desirable that the length of the screw is such that the head of the screw 8 and the surface of the fixing frame 2 are flush with each other.

The upper end of the fixing frame 2 of the jewelry table 1 is in contact with the jewel 4 so as to be hidden by the girdle 5 from the upper part and below the girdle 5 of the jewel 4. The fixed frame 2 is not limited to the annular one shown in FIG. 1 (b). For example, a plurality of fixed frames divided into a jewel table 1 are provided, and upper ends of the plurality of fixed frames are hidden by a girdle. It may be in contact with jewelry so that it cannot be seen.

In the mounting structure according to the present embodiment, the jewel 4 is placed on the upper end of the fixing frame 2 of the jewel table 1, and the locking hole 7 provided in the jewel 4 and the through hole 7 provided in the jewel table 1 coincide with each other. Then, the screw 8 is screwed into the through hole 9, and the tip of the screw 8 is inserted into the locking hole 7. Similarly, screws 8 are screwed into the other through holes 9, the tips of the screws are inserted into the locking holes 7, the insertion amounts of the screws 8 are adjusted, and the jewels 4 are locked by the screws 8 so that the jewels 4 are locked. Support and fix to the table 1.

FIG. 2 shows a rod-shaped fixture, (a) shows a pin, and (b) is a schematic diagram showing a nail. A screw is inserted into a through hole 9 on the side surface of the fixed frame 2 of the jewelry table 1 shown in FIG. The pin 8a or the nail 8b can be used without providing the gem 4. When the jewel 4 is supported and fixed using the pin 8a or the nail 8b, the tip of the pin 8a or the nail 8b is inserted into the locking hole 7 of the jewel 4. After the jewel 7 is fixed in place, the rear end of the pin 8a or the nail 8b is welded to the fixing frame 2. The welding is preferably performed by laser welding which does not affect the jewel 4, and the rear end of the pin 8a or the nail 8b is preferably finished so as to be flush with the surface of the fixed frame 2.

FIG. 3 is a schematic sectional view showing another embodiment of the present invention. In this embodiment, a threaded through-hole 9 is provided in one side of the fixing frame 2 of the jewelry table 1, and the opposite side is provided. The locking projection 10 for locking in the locking hole 7 of the jewel 4 is provided integrally with the fixed frame 2.

In the present embodiment, after the locking projection 10 of the fixing frame 2 is locked in the locking hole 7 of the jewel 4, the screw-formed through hole 9 is aligned with the locking hole 7 of the jewel 4. The screw 8 is screwed in, the tip of the screw 8 is inserted into the locking hole 7, and the jewel 4 is supported and fixed to the jewel table 1. In this embodiment, since the locking projection 10 of the fixing frame 2 is only partially engaged with the locking hole 7 of the jewel 4 instead of the screw, the work of attaching and detaching the jewel 4 becomes easy.

[0018]

[Effect of the invention]

 In the present invention, since the upper end of the fixing frame is supported and fixed at the lower part of the girdle of the jewel by the rod-shaped fixing tool, the jewel can be easily supported and fixed without skill. In addition, since the upper end of the fixed frame is located below the girdle of the jewel, the jewel looks larger and more beautiful than when supported by nails, so that the appearance is improved.
