Abstract
A ring mechanism for retaining loose-leaf pages includes a housing and ring members for holding loose-leaf pages that are moveable relative to the housing between an open and closed position. An actuation system moves the ring members and includes hinge plates pivotally mounted on the housing and an actuator actuating pivoting movement of the hinge plates. A travel bar of the actuation system is moveable by the actuator between a locked position blocking pivoting movement of the hinge plates and an unlocked position allowing pivoting movement of the hinge plates. The actuation system is adapted to deform while moving the travel bar from the locked position toward the unlocked position to delay the pivoting motion of the hinge plates from the movement of the actuator.
