[0015] Hereinafter, a finger ring according to an embodiment of the present invention and a method for manufacturing the same will be described. FIG. 1 is a perspective view showing the appearance of a finger ring 11 according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of the finger ring 11 taken along the line AA shown in FIG. In this embodiment, gold is exemplified as an example of the precious metal of the present invention, but the precious metal may be platinum, silver, or the like other than gold.

[0016] As shown in FIGS. 1 and 2, the finger ring 11 has, for example, a ring body 21, a reinforcing member 23, and a gold member 25. The ring body 21 is made of ceramic and has an annular shape. The ceramic material may be, for example, zirconia or alumina. The ring body 21 is made of ceramic, which serves as a measure against metal allergies. The ring body 21 has an annular recess 31 formed on its outer circumferential surface along the outer periphery. As shown in FIG. 2, the cross section of the ring body 21 has a shape in which an opening 33 of the recess 31 is formed.

[0017] The reinforcing member 23 has an annular shape and is positioned within the recess 31 of the ring body 21 . The cross section of the reinforcing member 23 is circular as shown in FIG. The reinforcing member 23 is made of a material, such as brass, which is stronger than the metal member 25 and is also less expensive. By disposing the reinforcing member 23 in the recess 31, the amount of expensive gold material 25 used can be reduced compared to when the gold material 25 is filled entirely inside the recess 31. In addition, the reinforcing member 23 can increase the strength of the entire ring 11.

[0018] As shown in FIG. 2, the gold member 25 has an annular thin-film shape, and is located on the opening 33 side of the recess 31 with respect to the reinforcing member . The metal member 25 is formed so as to cover the entire area of ​​the reinforcing member 23 on the recess 31 side. Specifically, the gold member 25 is joined (fixed) so as to come into surface contact with the outer circumferential surface of the gold member 25 on the recess 31 side. By forming the gold member 25 in this manner, the gold member 25 is visible from the outside (the visible side) of the ring, but the reinforcing member 23 is not. This allows the gold member 25 to be incorporated into the ring body 21, resulting in an excellent aesthetic appearance.

[0019] A method for manufacturing the ring 11 shown in Figs. 1 and 2 will now be described. FIG. 3 is a flowchart for explaining a method for manufacturing the finger ring 11 according to the embodiment of the present invention. FIG. 4 is a perspective view of the ring body 21 of the finger ring 11 according to the embodiment of the present invention. FIG. 5 is a side view of ring body 21 of finger ring 11 according to an embodiment of the present invention. FIG. 6 is a BB cross-sectional view of the ring body 21 shown in FIG.

[0020] Each step shown in FIG. 3 will now be described. Step ST1: A ceramic ring body 31 having a recess 31 formed annularly along the outer periphery on its outer periphery as shown in Figs. 4 to 6 is prepared.

[0021] STEP ST2: As shown in FIG. 7, a linear reinforcing member 23 is prepared and inserted into the recess 31 of the ring body 21 so as to come into contact with the bottom of the recess 31. Next, both ends of the reinforcing member 23 are heated and welded (joined) to form a ring. At this time, both ends of the reinforcing member 23 are welded so that the reinforcing member 23 is stably fixed in the recess 31 .

[0022] Step ST3: As shown in FIG. 8, a linear, thin-plate metal member 25 is prepared and placed on the reinforcing member 23 located in the recess 31.

[0023] Step ST4: As shown in FIG. 2, the metal member 25 is pressed toward the reinforcing member 23, and the metal member 25 is fixed to the outer peripheral surface of the reinforcing member 23 on the opening 33 side. At this time, the joint between the gold member 25 and the reinforcing member 23 is heated and brazed so that the gold member 25 is stably formed (fixed) on the outer circumferential surface of the reinforcing member 23. There is a welding effect due to the material between the metal member 25 and the reinforcing member 23. The reinforcing member 23 may be made of a material other than metal, and in that case, depending on the material, it may be fixed by adhesive. In this way, the ring 11 shown in FIG. 2 is manufactured. Some or all of the above steps may be performed by a manufacturing device or manually.

[0024] As described above, according to the finger ring 11, by positioning the gold member 25 in an annular shape in the center of the circumferential surface of the ring body 21, it is possible to create an excellent aesthetic appearance by combining ceramics and gold.

[0025] According to the ring 11, the reinforcing member 23 is disposed in an annular shape in the recess 31 of the ring body 21, so that high strength can be obtained. According to the ring 11, by forming the gold member 25 on the entire area of ​​the reinforcing member 23 on the opening 33 side, only the gold member 25 is visible from the opening 33, and the reinforcing member 23 is not visible. Therefore, an excellent aesthetic appearance can be obtained. Furthermore, according to the ring 11, by making the gold member 25 thin plate-like, the amount of gold used can be reduced, leading to a reduction in cost.

[0026] Moreover, the process shown in FIG. 3 can be used to manufacture the ring 11 having the structure shown in FIG. 1 and FIG.

[0027] The present invention is not limited to the above-described embodiments. In other words, those skilled in the art may make various modifications, combinations, sub-combinations, and substitutions of the components of the above-described embodiment within the technical scope of the present invention or an equivalent scope.

[0028] In the above embodiment, the recess 31 having the shape as shown in FIG. 2 is formed in the ring body 21, but the shape of the recess 31 may be other shapes, such as a shape having a curved surface. In the above embodiment, the ring body 21 is provided with the annular recess 31 on the outer periphery thereof, but the recess 31 may be provided only on a portion of the outer periphery in the circumferential direction.

[0029] In the above embodiment, the reinforcing member 23 has a circular cross section, but the cross section may be other than a circle, such as a rectangle. Furthermore, the thickness etc. of the metal member 25 is not particularly limited.

[0030] Furthermore, the method for manufacturing the ring 11 shown in FIG. 3 is not particularly limited. For example, the gold member 25 may be joined to the reinforcing member 23 and then inserted into the recess 31 . Moreover, the reinforcing member 23 may be formed into an annular shape and then inserted into the recess 31 . [Industrial Applicability]

[0031] The present invention is applicable to finger rings and methods of manufacturing same. [Explanation of symbols]
