Segmented paper lifter with multiple and variable length lever arms

An improved paper lifter connected slidably and pivotally to rings of a ring binder, the improvements comprising:

• a multiplicity of support segments distributed along an elongated side of the lifter;
• aperture segments of the support segments having apertures adapted to receive the rings, the connection between the lifter apertures and the binder rings forming contact points along a pivot axis, the aperture segments interconnectedly interspersed between the support segments, the aperture segments forming an aperture set;
• a multiplicity of different load arms affixed to corresponding support segments, the load arms extending from the pivot axis inward toward alternate contact points with the binder, the alternate contact points between lifter and binder substantially removed from the pivot axis;
• and
• a plurality of load arm sets comprising support segments of like load arms.

An improved paper lifter co-acting with a ring binder having binder covers with a spline therebetween, a plurality of split rings emerging from a protective cover over a ring mechanism mounted on the binder, the improvements comprising:

• a support segment having apertures along an elongated side of the lifter, the apertures slidably and pivotally connecting the lifter to the rings along a pivot axis;
• a plurality of sets of inner lifter edges adapted to form slidable and pivotal contact points between the inner lifter edges and predetermined alternate binder surfaces, the surfaces generally near the center of the rings;
• and
• means for affixing the inner edges to the support segment, the means forming sets of load arms of different lengths between the pivot axis and sets of like inner lifter edges.
