ABSTRACT:
A page lifting device for use with looseleaf binders containing binding rings. The leaves of the page lifter are formed from one or more, rigid or flexible sheets of material or loops of stiff wire affixed at their inner edges to the inside of the binder at the base of the binding rings by hinged or flexible means. They can contain slots therein, which allow them to fit over the binder rings on closing, or be one or more rigid or flexible sheets located between the binder rings, and affixed to the inside of the binder such that the leaf or leaves envelope and lift the looseleaf pages away from the binder spine on closing.
