ABSTRACT OF THE DISCLOSURE A collapsible saw-horse is disclosed, comprising a beam and two frames extending side by side from the underside and longitudinally of the beam, and each forming a pair of legs for supporting the beam. Each frame consists of a single bent tubular member defining two upright leg portions and an intermediate bight portion at the lower end of the leg portions. The upper ends of the leg portions are bent back and inserted within brackets secured to the underside of the beam. One frame is rigidly secured to the brackets by screws extending through the brackets to take a collapsed position parallel to the first frame and an operative beam-supporting position diverging from the first frame. A pair of pivoted toggle arms link the two frames to prevent the pivotable frame from spreading beyond a predetermined limit angle with respect to the fixed frame.
