Abstract

A ring binder mechanism for retaining loose leaf pages has a housing and pivoting hinge plates supported by the housing. The mechanism has an actuator mounted on the housing and moveable between open and closed positions to pivot the hinge plates and thereby open and close rings of the mechanism. An elongate travel bar is operatively connected to the actuator for movement of the travel bar longitudinally in the housing by the actuator. The travel bar has a plurality of locking elements and a cam. The locking elements are positioned to block pivoting movement of the hinge plates when the actuator and rings are in the closed position and the locking elements are in a locking position. The cam extends into an opening in the hinge plates. The cam helps the actuator drive pivoting movement of the hinge plates.
