Abstract
A ring metal (10) has binder rings (12-16) each comprised of two ring segments one end of each of which is attached to a hinge plate (18, 20). A movable bar (34) extends from one end of the metal to the other and contacts the hinge plates to move them when the binder is opened. A manually operated trigger (32) connects to one end of the bar to move the bar. The trigger includes a slot (40) in which is fitted a pin (44) connected to the bar. The pin moves in the slot as the trigger is moved. Drawing the trigger away from a binder closed position toward a binder open position moves the pin through the slot. This causes the bar to move relative to the hinges, forcing the hinges to pivot the respective segments of each binder ring away from each other and open the binder. When the binder is closed, a nib (62) formed on the top of the bar is received in an opening in a shield (22) of the metal to prevent the trigger from being inadvertently moved and opening the binder. A cushion member (66) slideably engages the trigger to partially cover the trigger.
