A collapsible sawhorse includes a channel-shaped beam having a hollow interior and a pair of leg assemblies attached to the beam at opposite ends thereof. Each leg assembly includes a bracket which is attached to the beam, a block which is connected to the bracket for pivoting about an axis transverse to the beam, and a pair of legs which are attached to the block for pivoting about an offset axis which extends crosswise with respect to the transverse axis. The legs of each leg assembly move toward and away from the hollow interior of the beam when the block of that assembly pivots about the transverse axis, while the legs move toward and away from each other when pivoted about the offset axis. The legs of each leg assembly may be brought to a folded condition in which they are located side-by-side and in this condition they will fit into the interior of the beam. When the sawhorse is erected, the legs of one of the leg assemblies are fixed with respect to the block of that assembly in that they cannot pivot with respect to that block about the offset pivot axis or the beam, but the legs of the other leg assembly can pivot with respect to the block of that leg assembly, again about the offset pivot axis. This enables all four legs to come to rest on a floor so that the sawhorse assumes a stable position, even if the floor is uneven.

A collapsible sawhorse comprising: a channel-shaped beam having parallel side walls which lie along a hollow interior; first and second leg assemblies attached to the beam at opposite ends thereof, each leg assembly including a pivot block which pivots relative to the beam about a first axis that is transverse to the beam and a pair of legs which pivot about a second axis relative to the block between a folded position, wherein they are side-by-side and against each other, and an open position, wherein they are spread apart, the second axis being fixed in position with respect to the first axis and oriented crosswise with respect to the first axis, the legs when in their folded position being capable of fitting into the hollow interior of the beam between the parallel side walls, with the folded legs of the first leg assembly overlying the folded legs of the seconded leg assembly; whereby the sawhorse collapses into a highly compact configuration; and means carried by a leg of the first leg assembly for engaging in a side-wall of the beam and thereby preventing the legs assemblies from pivoting about the first axes and swinging out of the hollow interior of the beam.
