A tubular frame structure for enclosing a storage area having a pair of tubular frame sections located in juxtaposition to each other with the storage area located therebetween. Extending across the storage area and connecting the frame sections is an enclosed housing. A flexible sheet material cover is located within the storage area. This cover has an open bottom which is to be movable between a lower (covering) position to an upper (uncovering) position. The movement of the cover is accomplished by means of a pair of cables which are conducted through the tubular frame sections. These cables are in turn connected to an electrically operated motor device mounted within the housing.
