Abstract

A ring mechanism has housing supporting pivoting hinge plates. The mechanism has rings for holding loose-leaf pages. An actuator is mounted on the housing for causing pivoting motion of the hinge plates to open the rings. The mechanism includes a travel bar and intermediate connector connecting the travel bar to the actuator so movement of the actuator to pivot the hinge plates causes longitudinal movement of the travel bar. The intermediate connector and travel bar are formed as one piece and have a living hinge adapted to allow the intermediate connector to pivot relative to the travel bar. The mechanism has a locking element moveable with the travel bar between a locking position and non-locking position. The living hinge is constructed to maintain a substantially constant spacing between the intermediate connector and the travel at points of connection of the living hinge to the intermediate connector and travel bar.
