  • Patent number: 4951782
    Abstract: A foldable sawhorse is disclosed having a main set of leg members with a beam across the upper edges thereof, and a shorter, supporting set of leg members pivotally secured to the main leg members. Strut members extend between the main and supporting legs on each side of the sawhorse, the struts being foldable as the sets of leg members are folded together, the legs and struts assuming a nesting relationship for presenting a thin, folded profile for storage and/or transport. The center support beam is vertically aligned with the midpoint of the open legs to evenly distribute the weight between the uneven length sets of leg members.
