ABSTRACT:
An erectable sawhorse including a frame and a pair of leg assemblies moveably attached to the frame, each of which can be pivoted between a collapsed position against an upper rail of the frame and an erected position away from the frame. When both legs are erected, the sawhorse can be placed upright on a supporting surface and used. Each leg is pivotally attached to the frame by a mechanism which permits the leg to be first pivoted between the upper rail and the end of the frame and second pivoted about the frame end to the erected position. A guide track attached between the upper rail and the frame end acts between the frame and the leg assembly by guiding the leg assembly through its first and second pivots.
