Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
163 words
A multipartite item of jewelry particularly useful as a finger ring comprising: eight hollow tubular sections each formed as a circular arc subtending an angle of 90° arranged together end-to-end to form an overall endless closed loop, the ends of each of said sections being movable relative to the ends of each adjacent section to enable said sections to be turned relative to each other; and flexible means resiliently holding said curved sections together in the form of said overall endless closed loop while enabling said sections to be turned end-to-end relative to each other; said flexible means enabling said overall endless closed loop to be twisted upon itself to form said jewelry item into a smaller closed loop formed of two generally overlapping circular segments while maintaining the ends of adjacent sections in abutting contact; said overall endless closed loop having a circumferential dimension which is at least twice as large as the circumferential dimension of said smaller closed loop formed therefrom.
Claim 2
Dependent Claim
163 words
