Abstract
A ring binder mechanism has a housing and hinge plates supported for pivoting movement by the housing. The mechanism has rings, each including a first ring member mounted on a first hinge plate and a second ring member. The first ring member is movable relative to the second ring member between open and closed positions. The mechanism has a travel bar and a locking element that are free of fixed connection to the hinge plates and movable in translation relative to the housing and hinge plates. The travel bar blocks pivoting motion of the hinge plates when the ring members are closed. An elongate link connects a pivotable actuating lever to the travel bar such that pivoting motion of the actuating lever produces translational movement of the travel bar. The elongate link is oriented so it extends longitudinally relative to the housing.
