Abstract
A ring binder mechanism for holding loose-leaf pages has a housing and rings movable between closed and open positions. The rings are mounted on hinge plates supported by the housing for pivoting movement relative to the housing. An actuator is moveable relative to the housing to pivot the hinge plates to move the rings between the closed and open positions. A travel bar operatively connected to the actuator includes a locking element. The travel bar is moveable between a locked position in which the locking element blocks pivoting of the hinge plates and an unlocked position in which the locking element permits pivoting of the hinge plates. The travel bar and housing each include a retaining formation. The retaining formation on the housing is adapted to contact the retaining formation on the travel bar to releasably hold the travel bar in the locked position when the rings are closed.
