Fitting device for ring

Abstract

There is provided a fitting device for a ring including: a multi-turned coil made of a metallic wire, the coil having equal pitch and constant coil diameter; one stopper formed into a spherical body and provided at one end of the wire; and the other stopper formed into a spherical body and provided at the other end of the wire. The one and the other stoppers are made of metal. The one and the other stoppers are arranged so that when seen from an axis of the coil, the one stopper and the other stopper are arranged at an interval along a circumference of the coil and so that the one stopper is located in the vicinity of an end of a palm and the other stopper is located in the vicinity of a base of a finger.

1 . A fitting device for a ring comprising:
 a multi-turn coil having an equal pitch and having a constant coil diameter, the coil being made of a wire;   one stopper formed into a spherical body and provided at one end of the wire; and   the other stopper formed into a spherical body and provided at the other end of the wire,   wherein the wire, the one stopper and the other stopper are made of metal,   wherein when seen from an axis of the coil, the one stopper and the other stopper are arranged at an interval along a circumference of the coil, so that the one stopper is arranged to be located in the vicinity of an end of a palm and the other stopper is arranged to be located in the vicinity of a base of a finger.   
     
     
         2 . The fitting device according to  claim 1 , wherein the one stopper and the other stopper are arranged such that an angle θ between a first line, the first line connecting a center of the one stopper and a circumferential center of a turn at one end of the coil, and a second line, the second line connecting a center of the other stopper and a circumferential center of a turn at the other end of the coil, is substantially right angle. 
     
     
         3 . The fitting device according to  claim 1  or  2 , wherein the metal constituting the wire, the one stopper and the other stopper is stainless steel. 
     
     
         4 . The fitting device according to  claim 1  or  2 , wherein the wire and the one and the other stoppers are coated with material selected from the group consisting of gold, rhodium and platinum. 
     
     
         5 . The fitting device according to  claim 3 , wherein the wire and the one and the other stoppers are coated with material selected from the group consisting of gold, rhodium and platinum.
