ABSTRACT:
A safety ring binder mechanism helps prevent finger pinching by requiring simultaneous opposite movement of sliding actuators at both ends of the mechanism in order to open and close the rings. When the actuators are outermost, dimples on the actuators press the blades of the device against the housing, holding the rings open. When the actuators are pushed in, inclined tongues cam the ends of the blades downward, forcing the rings to close and holding them in a closed position.
