ABSTRACT:
A looseleaf binder assembly consisting of a backbone member and a second member that has fastened thereon a plurality of resilient rounded fingers in a position that will accept a plurality of loose sheets is disclosed. The second member contains an inwardly facing continuous flange on the body of the second member and inwardly facing tangs on the end of each resilient finger. These tangs and continuous flange slide into the grooves of the backbone member until each member is substantially aligned. The two members lock in position, when in alignment, by two of the resilient fingers snapping into notches in the grooves of the backbone member. In order to remove the looseleaf sheets, the two resilient fingers are deflected outwardly to allow the two tangs to clear the two notches where the continuous flange of the second member and the remaining tangs on the resilient fingers can slide out of the grooves in the backbone member.
