Patent attributes
A ring mechanism for retaining loose-leaf pages comprises a housing and hinge plates supported by the housing for pivoting motion relative to the housing. Rings for retaining the loose-leaf pages comprise ring members mounted on the hinge plates for movement with the hinge plates between an open and closed position. An actuator mounted on the housing is moveable between a first position in which the ring members are open and a second position in which the ring members are closed. The actuator is in continuous engagement with the hinge plates when the ring members are closed resisting movement of the actuator. A travel bar is operatively connected to the actuator for movement with the actuator. The travel bar resists movement of the actuator when the ring members are open.
