A ring binder includes a substantially rigid curved upper plate supporting a pair of hinged leaves. A plurality of ring members are secured to the hinged leaves for engaging corresponding holes in sheets of material retained by the ring binder. An actuating lever is located at each end of the curved upper plate for actuating the hinged leaves to open and close the ring members. Each actuating lever includes a tab having a pair of spaced-apart apertures therein. A cushion member is located on the tab, which includes an inner cushion part and an outer cushion part which are interconnected by a pair of connecting parts which extend through the spaced-apart apertures in the tab to securely attach the cushion member to the tab. The cushion member is engaged by the fingers of a user to pivot the actuating lever in order to move the ring members between the open position and the closed position. The cushion member is a soft pad of resilient material such as rubber or soft plastic. The cushion member provides improved tactile characteristics to the actuating lever, making the actuating lever comfortable to use. The cushion member also minimizes the feedback of undesirable shock forces produced by the snap action of the rings when opening and closing the rings.
A ring binder comprising:
In combination, a ring binder having a pivotable actuating lever including a tab at an upper end portion thereof having a pair of spaced-apart apertures therein, and a cushion member including an inner cushion part located on an inner face of said tab, an outer cushion part located on an outer face of said tab, and a pair of spaced-apart connecting parts which extend through said spaced-apart apertures in said tab to securely attach said cushion member to said tab.
