Abstract:
A collapsible sawhorse, comprising two substantially identical side panels, dual link assemblies, and a top rail;each side panel having two upstanding legs and upper and lower cross members extended between the legs and defining a window opening, laterally spaced mutually complementary hinging structures formed along each upper cross member operable with the side panels oriented back-to-back to hinge the side panels together for limited rotation about an axis spaced slightly above the upper cross members; each of the link assemblies having a pair of links and means for pivoting corresponding ends of the links together, each of said link assemblies fitting in a folded side-by-side orientation between corresponding upstanding legs of the side panels when the sawhorse is closed, and means for pivoting the opposite link ends to the side panels operable to allow limited rotational separation of side panels from the sawhorse closed position to the sawhorse opened position, with said links then being mutually aligned and extended transverse to the side panels; and the top rail having a top wall and peripheral walls angled transverse therefrom, the top rail fitting over the side panel hinging structures, and means for holding the top rail to the side panels for maintaining the hinging structures together and for distributing loads carried on the sawhorse to the underlying side panels; and said holding means comprising a single substantially cylindrical locking pin supported by each side panel between one side edge and the adjacent endmost hinging structure, each locking pin being coaxial with the hinge axis, and a pair of loops formed off of the top wall and laterally between the peripheral walls to be equally spaced from the adjacent top rail end and spaced apart by the approximate separation of the locking pins, suited to fit under and around the pins so as to become locked thereon while the holding means is virtually hidden behind the peripheral walls.
