Jewelry link with spring closure

Abstract

A jewelry link with spring closure is described herein, the jewelry link having a link body and a barrel structure housing a spring, the spring configured to exert a force on the barrel structure to keep the jewelry link in a closed passive state. The link body having two ends that meet with, and couple to, a top and bottom of the barrel structure, respectively. One of the two ends of the link body may comprise a piston structure configured to move up and down an internal shaft within the barrel structure, at least partly due to a force exerted by the spring. The barrel structure may include a mating structure configured to couple to another of the two ends of the link body.

What is claimed is: 
     
         1 . A jewelry link with spring closure comprising:
 a link body comprising two ends;   a barrel structure comprising a smaller diameter shaft configured to receive a first of the two ends and a larger diameter shaft configured to receive a second of the two ends; and   a spring housed at least partially within a groove in the second of the two ends, the spring configured to exert a force on the barrel structure in the direction of the first of the two ends, thereby closing the jewelry link,   wherein the second of the two ends comprises a piston structure configured to move up and down the larger diameter shaft.   
     
     
         2 . The jewelry link of  claim 1 , wherein an external surface of the barrel structure comprises a hexagonal cylinder. 
     
     
         3 . The jewelry link of  claim 1 , wherein an external surface of the barrel structure comprises a round cylinder. 
     
     
         4 . The jewelry link of  claim 1 , wherein the link body comprises one, or a combination, of a circular loop, an oval loop, a square loop, a rectangular loop, a square loop with rounded edges, a rectangular loop with rounded edges, a hexagonal loop, an octagonal loop, a partially rounded loop, and an oblong loop. 
     
     
         5 . The jewelry link of  claim 1 , wherein the first of the two ends comprises a male coupling structure complementary to a female coupling structure on the smaller diameter shaft, or vice versa. 
     
     
         6 . The jewelry link of  claim 1 , wherein the first of the two ends comprises a screw groove. 
     
     
         7 . The jewelry link of  claim 5 , wherein the smaller diameter shaft comprises a complementary groove configured to mate with the screw groove of the first of the two ends. 
     
     
         8 . The jewelry link of  claim 1 , wherein the jewelry link with spring closure comprises a ring, in whole or in part. 
     
     
         9 . The jewelry link of  claim 1 , wherein the jewelry link with spring closure comprises a bracelet, in whole or in part. 
     
     
         10 . The jewelry link of  claim 1 , wherein the jewelry link with spring closure comprises a necklace, in whole or in part.
