Claim 0:
1. A collapsible rack assembly for use on a vehicle having a flat bed to carry longer loads such as pipes or a ladder, the rack comprising:
a linearly elongated tubular rectangular frame having a proximal end opposite a distal end the frame comprised of:
two support segments opposite each other at the proximal and the distal end, and
two extension segments opposite each other and joining said support segments;

four tubular legs hingedly attached to said extension segments and movable in a plane perpendicular to said frame, one leg at the proximal end and one leg at the distal end of each said extension segment;
four rectangular flanges that protrudes the distance of at least the diameter of said leg into the space enclosed by said frame, each flange is attached to the bottom of said extension segments, one flange at the proximal end and one flange at the distal end of each said extension segments;
four braces each hingedly attached to each said flanges along the edge that protrudes into the space enclosed by said frame;
two crossbeam assemblies, one at the proximal end and the other at the distal end of said frame, each crossbeam assembly having:
one tubular horizontal member; and
two vertical members such that each vertical member may be slideably inserted into said legs at either the proximal end or the distal end of said frame to mount the crossbeam assembly into said frame.
