Moveable file storage supporting apparatus

An apparatus for movably supporting a storage system on a floor comprising:

• a plurality of generally rectangular flat tracks fixedly disposed on the floor generally parallel to one another;
• a corresponding plurality of support assemblies, each of said support assemblies including a pair of vertically oriented support wheels each having a spherical profile and a frame for supporting said support wheels rotationally thereon;
• only one of said support assemblies including a pair of guide rollers rotationally supported by said frame so as to face opposite side edges of said flat track when said one support assembly is disposed with its said support wheels resting on one of said flat tracks;
• an elongated drive track including:
• a secondary track member adapted to be fixedly secured to said floor and to be disposed adjacent to one of said flat tracks;
• and
• an elongated chain disposed fixedly within said secondary track member,
• wherein said secondary track member and said flat track each include openings therethrough such that said secondary track member can be secured between a lower surface of said flat track and said floor by at least one threaded member extending into said floor;
• a drive shaft operably interconnecting each of said support assemblies so as to move each of said support assemblies longitudinally therewith when said drive shaft moves longitudinally;
• a toothed drive element fixedly associated with said drive shaft and engaged with said chain;
• and
• a drive mechanism operably associated with said drive shaft to enable rotation of said toothed drive element rotationally along said chain, to thereby enable movement of said storage system along said flat tracks.

A storage supporting apparatus disposed on a floor for movably supporting a storage system, wherein the storage system has a plurality of interconnected storage units, said storage supporting apparatus comprising:

• a plurality of flat tracks secured to the floor generally parallel to one another and in spaced apart relation to one another;
• a corresponding plurality of support assemblies for supporting said storage system movably on said flat tracks;
• each of said support assemblies comprising a pair of elongated rods extending within an associated elongated tubular member which interconnects one of said support assemblies to an adjacent said support assembly for providing rigidity to said support assemblies and to thereby inhibit said support assemblies in changing configuration from a rectangle to a parallelogram as said support assemblies are moved longitudinally;
• each of said support assemblies further comprising a pair of support wheels mounted for rotational movement to support said storage system for rolling movement on an associated one of said flat tracks, such that all of said support assemblies can be moved simultaneously on said flat tracks, and a pair of guide rollers associated with only one of said support assemblies disposed perpendicular to said associated support wheels of said associated support assembly, each of said guide rollers being disposed closely adjacent to opposing side edges of said flat track on which said associated support wheels are supported to enable said associated said support assembly to move longitudinally along said associated flat track.
