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.

New and improved Sheet Lifter for use with a three ring binder containing a plurality of pages or sheets where the three ring binder has a first ring, a second ring and a third ring, the rings having a predetermined distance from the first ring to the third ring, further the rings having a predetermined diameter, an inner surface and an outer surface, and further said three ring binder having a spine, comprising:
- a.) a flat panel, said flat panel being made of rigid material from the group of materials that have a position memory, said flat panel having a first end, a middle section and a second end, further said flat panel having a length dimension, a width dimension and a thickness dimension, the flat panel length dimension being longer than the distance from the first ring to the third ring of the three ring binder, the width dimension being approximately equal to one half the diameter of the rings of the three ring binder, further the flat panel having a top edge that is straight and a bottom edge that has a slight curvature, said flat panel having an elongated notch at the bottom edge near the first end and a short notch at the bottom surface at the second end, both notches being L shaped, with the elongated notch having a knob, the flat panel remains rigid and supports the pages or sheets when two of the flat panels are positioned in opposition with the bottom edge resting on the three ring binder spine with the flat panels first end extending thru the first ring being engaged with said first ring at the elongated notch and resting against the inner surface of said first ring, further with the flat panels middle sections resting against the second ring outer surface and further with the flat panels second end extending thru the third ring being engaged with said third ring at the short notch and resting against the inner surface of said third ring.
New and improved Sheet Lifter for use with a multi ring binder containing a plurality of pages or sheets where the multi ring binder has a first ring, a second ring and a third ring, and at least a fifth ring, a sixth ring and a seventh ring the rings having a predetermined distance from the first ring to the third ring, said distance being the same as the distance from the fifth ring to the seventh ring, further the rings having a predetermined diameter, an inner surface and an outer surface, and further said multi ring binder having a spine, comprising:
- a.) a plurality of flat panels, said flat panels being made of rigid material from the group of materials that have a position memory, said flat panels having a first end, a middle section and a second end, further said flat panels having a length dimension, a width dimension and a thickness dimension, the flat panels length dimension being longer than the distance from the first ring to the third ring of the multi ring binder, the width dimension being approximately equal to one half the diameter of the rings of the multi ring binder, further the flat panels have a top edge that is straight and a bottom edge that has a slight curvature, said flat panels have an elongated notch at the bottom edge near the first end and a short notch at the bottom surface at the second end, both notches being L shaped, with the elongated notch having a knob, the flat panels remain rigid and support the pages or sheets when two of the flat panels are positioned with the bottom edge resting on the multi ring binder spine with the flat panels first ends extending thru the first ring being engaged with said first ring at the elongated notch and resting against the inner surface of said first ring, further with the flat panels middle sections resting against the second ring outer surface and further with the flat panels second ends extending thru the third ring being engaged with said third ring at the short notch and resting against the inner surface of said third ring and two of the flat panels are positioned with the bottom edge resting on the multi ring binder spine with the flat panels first ends extending thru the fourth ring being engaged with said fourth ring at the elongated notch and resting against the inner surface of said fourth ring, further with the flat panels middle sections resting against the fifth ring outer surface and further with the flat panels second ends extending thru the sixth ring being engaged with said sixth ring at the short notch and resting against the inner surface of said sixth ring.
