ABSTRACT OF THE DISCLOSURE An improved foldable leg assembly for dual-height workbenches and like devices which is simple to construct, requires no foldable braces or stays, employs an extremely simple hinge plate structure to connect same to a workbench base, the legs being oriented and arranged to provide adequate stability in the higher position of the workbench. The dual height workbench includes top members defining a working surface, a base defining longitudinal and transverse axes and support structure for supporting said top members above said base. A plurality of leg members are pivotally attached to said base adjacent outer edge portions of same and movable between inwardly folded inoperative positions corresponding to the lower height of the workbench and outwardly and downwardly inclined operative positions relative to said base corresponding to the higher position of the workbench. The pivotal attachment of the respective legs is such that each of said legs is capable of movement in an arc lying in a plane which is at an acute angle relative to the longitudinal and transverse axes of said base. Each said leg includes at its upper end pivot axis de- fining means, with a portion of said upper end spaced from said pivot axis defining means being shaped to transmit thrust forces to said base and to limit the degree of outward pivotal motion of said leg thus to define the outwardly and downwardly inclined operative position of each leg.
