Abstract
A ring binder mechanism has an elongate housing, a pair of locking elements, a translation bar, a pair of elongate hinge plates having mating ring halves extending there-from, a plurality of mating ring halves, and an actuator. Movement of the actuator moves the hinge plates, translation bar, and locking elements to cause the ring halves to disengage so a user can place holed paper over the open ring halves, or closes the ring halves together to secure the paper with the closed-loop rings thus form while simultaneously locking the rings in the closed-loop configuration to prevent inadvertent opening.
