Abstract:
1. A page lifting device, for use with a loose-leaf binder having front and back covers with inside surfaces that substantially face each other when the binder is closed, binding rings each of which when closed approximately forms a circle having a center and a line connecting the centers of at least two binding rings defines an axis, and a binding-ring base cover, which comprises: a) at least two page lifter portions hinge-mounted to an attaching member, b) at least one said page lifter portion located in front of any pages contained in the binder and at least one page lifter portion located behind them, c) each page lifter portion having an inner edge towards the hinge and an outermost edge away from the hinge, d) the attaching member having a height of the hinge above the binding-ring base cover such that the hinge is located at approximately the axis of the binding rings, e) said page lifting device is made from a material where a thin section of the material forms a flexure acting as the hinge, f) said attaching member is fixedly attached to the binding-ring base cover with pressure sensitive adhesive with a peel-off protective cover, whereby on closing the loose-leaf binder the outermost edges of the page lifter portions encounter the inside surfaces of the loose-leaf binder's front and back covers, forcing said page lifter portions to rotate about said hinge thereby lifting said pages on the binding rings away from the binding-ring base cover preventing the pages from being caught between the binding rings and the inside surfaces of the loose-leaf binder's front and back covers.
