Apparatus for supporting and storing engineering drawings and the like

Apparatus for supporting and storing large size paper sheets comprising a plurality of longitudinally aligned ring binder assemblies each of which includes a plurality of ring members which can be opened and closed and extended through holes formed in paper sheets to be supported, an elongated support member for said ring binder assemblies, at least one hinge assembly connected to and extending between said ring binder assemblies and said support member to enable pivotal movement of said ring members relative to said support member including means enabling disposition of said support member in a horizontal position with said ring binder assemblies therebelow and extending downwardly therefrom with said ring members extending generally horizontally to one side of said hinge assembly so that paper sheets can hang downwardly from said ring members, said apparatus being movable to a position in which said ring members extend upwardly to one side of said support member to facilitate laying of paper sheets on said ring members on a horizontal table surface.
