Mobile under-bed storage container

A mobile storage container readily disposable under the frame of a bed supported off the ground by legs, said container comprising;

• a box-like body structure having a bottom wall with upper and lower surfaces, a plurality of side walls, and an open top, the upper surface of said bottom wall adapted to support articles to be stored thereon;
• means for ventilating said body structure and for providing grasping thereof, said means including means defining at least one hand-hold cutout in a side wall;
• a plurality of caster assemblies having wheels extending downwardly from the lower surface of said bottom wall for supporting said body structure for rolling movement;
• means for mounting said caster assemblies so that the wheels thereof may rotate both about horizontal and vertical axis with respect to said body, said means for mounting each of said caster assemblies for rotary movement about a vertical axis including a metal mounting plate having one portion thereof substantially flush with the upper surface of said bottom wall and having another vertically and longitudinally displaced portion thereof attached to the lower surface of said bottom wall and a pivot pin extending outwardly from said one portion of said metal mounting plate and passing through an opening in a caster support structure, said pivot pin having an end thereof remote from said metal supporting plate with a projection that prevents the passage of the end thereof through said support structure opening while still allowing relative rotation of said support structure with respect to said pivot pin;
• a flexible material cover for said body structure to cover the open top thereof and to fit and extend over said side walls of said body structure;
• means for defining at least one opening in said flexible cover corresponding to the hand-hold cutout in said at least one side wall of said body structure;
• and the height D of the container from the bottom of said caster assemblies to the top of said side walls being less than the height of the bed frame supported off the ground by legs.
