ABSTRACT:
A ring that opens and closes securely is formed from two arcuate sections hinged together at one end. A rigid section carrying ornamentation is worn on the dorsal aspect of the finger. A resilient section is worn on the ventral aspect of the finger. Overlapping partial-thickness tongues extend from the free ends of the sections. When they overlap the tongue of the rigid section is outside the tongue of the resilient section. A pin extending radially from the tongue of the rigid section toward the axis of the ring engages a radial hole in the tongue of the resilient section which receives the pin and holds the ring securely closed. When the free ends of the sections are squeezed toward the hinge ends, the resilient section flexes more so that the hole moves away from the pin to permit free opening and closing of the ring.
