Abstract
A foldable, collapsible sawhorse that includes a rigid beam horizontally supported near its end by pairs of legs moveably connected to a rigid plate that is hinged to the beam. Each plate includes first and second areas that are angularly disposed relative to each other, with the first area having mounted thereupon a beam-receiving channel. The second area of the plate includes a circular aperture and an arcuate slot which are vertically aligned that receive fasteners for each support leg connected thereto. The legs are thus pivotal relative to the plate which allow them to be spread apart or placed in parallel by loosening of a single fastener for each leg. The beam channel includes apertures for fasteners which allow the beam to be hingeably moved relative to the beam-receiving channel on the plate. Thus, the sawhorse may be collapsed by moving the pairs of end legs to a central parallel position in the plane of the beam and then moving each set of legs substantially parallel to the beam. The angle between the first and second plate areas allows the legs to be parallel and in close proximity to the central beam in the collapsed position.
