Abstract:
Sheet Lifter for use with multi ring sheet or page holders and multi ring binders. The Device is made from a thin ridged panel with a plurality of notches and slots. The Device is positioned in order to interact with the rings and binder spine of the page holder or binder. The Device rests on the spine with the pages or sheets resting on the Device. The Device prevents the pages or sheets from traveling past the maximum horizontal diameter point of the rings when the holder or binder is fully opened. When the holder or binder is closed the Device creates sufficient upward pressure against the pages or sheets to return them to their closed position at the maximum vertical diameter point of the rings. The pressure required is minimal.
