Adjustable ring

Abstract

An adjustable finger ring may include a ring head having through holes on the bottom a first shank having shank collars as support at one end and a split portion at the other end, and a second shank having shank collars as support at one end and a split portion at the other end. The split portions may complement and overlap each other in an operative condition of the ring. A spring can be fitted inside the two supports with the coils of the spring aligned with the holes of the support of the first shank so as to allow a pin to pass through. The inward facing surfaces of the collars of the second shank may confront the outward facing surfaces of the collars of the first shank. The holes of the collars can be aligned so as to allow the pin to pass through. The two shanks may be hinged together and act as a spring clasp.

We claim: 
     
         1 . An adjustable finger ring comprising:
 a ring head having through holes;   a first shank having a pair of first shank collars at one end and a first split portion at the other end;   a second shank having a pair of second shank collars at one end and a second split portion at the other end;   wherein the first and the second split portions overlap each other;   a spring situated between the first shank collars and between the second shank collars, such that inward facing surfaces of the second shank collars confront outward facing surfaces of the first shank collars, and inward facing surfaces of the first shank collars confront the spring;   a pin extended through the through holes of the ring head, the first shank collars, the second shank collars, and coils of the spring;   wherein the first and the second shanks are hinged together for pivot action about the pin, such that the first and the second split portions are slidable over each other; and   wherein the spring influences the first and the second shanks to pivot about the pin in a closing direction.   
     
     
         2 . An adjustable finger ring as claimed in  claim 1 ,
 wherein the ring head is fabricated from silver;   wherein the first and the second shanks are fabricated from silver;   wherein the pin is fabricated from silver; and   wherein the spring is fabricated from steel.   
     
     
         3 . A method of making an adjustable finger ring, the method comprising:
 inserting a coil spring between two first collars of a first shank;   aligning the coils of the coil spring with holes provided in the first collars;   positioning a second shank having two second collars such that inward facing surfaces of the second collars confront outward facing surfaces of the first collars;   aligning holes provided in the second collars with the holes in the first collars;   positioning a ring head with through holes, such that the through holes are aligned with the holes in the second collars;   inserting a pin through the through holes of the ring head, the holes in the second collars, the holes in the first collars, and the coils of the coil spring; and   fixing ends of the pin to a bottom of the ring head.
