Claims

1. A knock-down support apparatus comprised of interlocking legs and a T-section cross-beam, said legs having T-shaped cuts extending downwardly from the middle of and partially across the top thereof whereby upwardly extending leg projections are formed on opposite sides of said T-shaped cuts in the upper portion of said legs, and said T-section cross beam is correspondingly cut with slots extending upwardly from the bottom of the vertical section and opposing notches on the sides of the horizontal section to interlockingly fit said upwardly extending projections in the horizontal section and overlappingly fit together along the vertically slotted portions of said legs.

2. Apparatus as defined in claim 1 wherein the top surfaces of the uncut portion of said legs and the horizontal section of said T-section cross beam form together a load bearing surface.
