File folders of the type having hooks to permit suspension for storage, and further including appendages to permit binding or compartmentalization of materials. The folder may contain loose-leaf binding rings, permanently or detachably mounted to the base. Alternatively, the folders are perforated at the base to hold a spiral binder for materials. The folders can be provided with telescoping side members to achieve an accordion-like effect. Such folders may additionally include permanent or removable divider panels.

A organizer for a large number of documents comprises a rigid backing member, a front cover and a back cover, both pivotally mounted to the backing member. The backing member is sufficiently wide to receive a plurality of removable parallel conventional ring binder assemblies and accordingly includes a plurality of mechanisms to receive the binder assemblies. The ring binder assemblies comprise a rigid spine, a plurality of rings and a mechanism to open and close the rings to receive perforated pages thereon. The front and back covers preferably provide handle holes set back from the edges a distance such that the end pages overlie the user's fingers when the organizer is picked up. In this fashion, the leading edges of the end pages do not cut the user's fingers. In addition, a retractable stand is provided for supporting the ring binders at an inclined readable angle.

A wrap-around notebook or binder includes a ring assembly with a shield and a pair of frames forming a bistable construction, and a hinge plate pivotally coupled to the shield with the outer surface of the hinge plate aligned with the outer extent of the shield/frame assembly when the hinge plate is parallel to the plane of the shield. The exposed frame member may be convex, recessed to receive rivet heads, and may be plated. The hinge plate(s) may have curls which interfit with alternate curls from the shield to provide a hinge. The ring assembly may be mounted in the notebook or binder so that the shield side of the ring assembly faces the front cover of the binder. The pivot line between the shield and the hinge plate may be spaced from the shield by a clearance distance. The notebook or binder lies flat on an underlying surface with either the front cover of the rear cover folded under the assembly.

A binder mechanism includes a rotatable support having ring segments that can be locked in a closed configuration. The binder mechanism includes a horizontal and/or a flush mounted push button that opens and/or unlocks the rotatable support. The push button acts on a ramped slider that causes the rotatable support to rotate open. An over-center arrangement aids in maintaining the binder mechanism closed or opened.
