Abstract
A movable cart having a collapsible frame with the frame being foldable into a collapsed or closed position for forming a narrow lateral profile and into an unfolded open position adapted to support a removable storage container. The frame comprises support members with each support member having a pair of legs extending downwardly from its opposite ends and a side arm extending between two of the legs on each opposite lateral side of the frame for securing the frame in the unfolded open position with the support members physically spaced apart to support the removable storage container. The side arms have hinges for folding the arms about a common plane lying in substantial parallel alignment with each support member. The frame also has a tray interconnecting the legs of the frame for forming a level platform adjacent the bottom end of the cart. The tray is foldable into substantially the same common plane into which the side arms fold so that upon folding the arms and tray, the cart collapses into the closed position with each of the support members drawn together into close proximity relative to one another.
