Collapsible sawhorse

Claim 1

A collapsible sawhorse moving between storage and load supporting positions, comprising an elongate beam of generally pentagonal cross-section having a length dimension, a width dimension and a thickness dimension, the beam having a planar upper surface corresponding to the base of the pentagon, a pair of generally parallel sides intersecting the upper surface and corresponding to the sides of the pentagon and first and second downwardly extending converging bottom faces intersecting the parallel sides; a first pair of generally straight parallel spaced legs having a long dimension and an end generally perpendicular to the long dimension, the end abutting the first bottom face of the base; means rigidly connecting the end and the first bottom face; a second pair of generally straight parallel spaced legs having a long dimension and an end generally perpendicular to the long dimension, the second legs being of generally the same size as the first legs; a pair of hinges connecting the first and second legs including a first arm connected to the first leg, a second arm connected to the second leg and a pivot connection located adjacent the convergence of the base bottom faces; the arrangement between the hinges and the second legs being such as to abut the ends of the second legs against the second bottom face in load supporting position of the sawhorse; means for limiting pivotal movement of the second legs relative to the first legs in a spreading direction; and means for selectively preventing pivotal movement of the legs toward each other.
