ABSTRACT:
A ring mechanism includes a chassis and a hinge blade coupled to the chassis. An actuator coupled to the chassis moves the hinge blade between a first position and a second position. A ring half coupled to the hinge blade is positioned in a closed position when the hinge blade is in the first position, and an open position when the hinge blade is in the second position. A dampening member is positioned at least partially between the inner surface of the chassis and the actuator to prevent at least a portion of the actuator from directly engaging the inner surface of the chassis during movement of the actuator between the first and second positions. A locked state indicator indicates to the user whether the ring mechanism is in a locked position or an unlocked position. The dampening member can function as the lock state indicator and vice versa.
