Claim 4:
5. 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:
one support segment at the distal end, and
two extension segments opposite each other and joining said support segment;

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