Abstract
A ring binder mechanism for retaining loose-leaf pages includes an elongate plate supporting two hinge plates for pivoting movement relative to the elongate plate. Ring members move with the pivoting movement of the hinge plates between a closed position for retaining loose-leaf pages on the mechanism and an open position for adding or removing pages from the mechanism. An actuating lever is mounted on the elongate plate for moving the ring members between their closed and open positions and for moving a travel bar in translation lengthwise of the elongate plate. A connector connects the lever to the travel bar so that the pivoting movement of the lever causes the translational movement of the travel bar. The connector is shaped to transfer force from the lever to the travel bar around a mounting post.
