Ring binder mechanism










Image Number 12 for United States Patent #8043018.

A ring binder mechanism has a housing supporting first and second hinge plates and rings, each ring including first and second ring members. The first ring member is mounted one of the hinge plates and moveable with the hinge plate relative to the second ring member between closed and open positions. An actuating lever for opening the rings is mounted on a pin secured to the housing. Pivoting of the actuator moves a travel bar relative to the hinge plates. A blocking element is secured to the travel bar for conjoint movement therewith between a locking position in which the blocking element blocks pivoting movement of the hinge plates to open the rings and a non-locking position in which the blocking element does not block pivoting movement of the hinge plates to open the rings. A torsion spring on the pin biases the actuating lever to its closed position.
