Collapsible and expandable rolling storage system

Abstract

A rolling storage system includes a substantially cubical case or housing having top, bottom, side, front and rear walls. The side walls are formed of two semi-panels. A hinge is provided for attaching the side walls to the front and rear walls and the semi-panels of each side wall to each other to selectively move the semi-panels of each side wall from a substantially common plane when the case or housing open or expanded to substantially parallel adjacent planes when the case or housing is closed or collapsed. The front and rear walls move from remote spaced positions when the case is open or expanded to proximate positions when the case is closed or collapsed. The top and bottom walls are movable to allow the case to be collapsed. The top wall selectively provides access or closing the case or housing. A rolling member is provided for rolling the case or housing when open or expanded. At least one auxiliary case or housing is provided dimensioned to substantially correspond to dimensions of the case or housing and having a footprint to allow stacking above the top wall. In this way both the case and auxiliary case can be transported together when attached.

1 . A rolling storage system comprising a substantially cubical case or housing having top, bottom, side, front and rear walls, said side walls being formed of two semi-panels; hinge means for attaching said side walls to said front and rear walls and said semi-panels of each side wall to each other to selectively move said semi-panels of each side wall from a substantially common plane when said case or housing open or expanded to substantially parallel adjacent planes when said case or housing is closed or collapsed, said front and rear walls moving from remote spaced positions when said case is open or expanded to proximate positions when said case is closed or collapsed, said top and bottom walls being movable to allow said case to be collapsed; said top wall selectively providing access or closing said case or housing; rolling means for rolling said case or housing when open or expanded; and at least one auxiliary case or housing dimensioned to substantially correspond to dimensions of said case or housing and having a footprint to allow stacking above said top wall, whereby both said case and auxiliary case can be transported together when attached. 
   
   
       2 . A storage system as defined in  claim 1 , wherein said walls are formed of thin metal sheet material. 
   
   
       3 . A storage system as defined in  claim 1 , wherein said rolling means are attached to said semi-panel closest to said rear wall and move therewith into a plane parallel to said rear wall when said case is collapsed.
