A new sawhorse bracket for use with a rectangular cross-section cross-bar, usually of wood, is formed preferably by stamping and subsequent bending from a continuous strip of metal, the bracket comprising a central portion of truncated isosceles triangle shape so as to have two inclined edges, leg supporting portions extending at right angles to the central portion, return portions extending at right angles to the leg-supporting portions, and end portions which engage the sides of the cross-bar. The bracket is fastened to the cross-bar by screws passing through the central portion and a single relatively heavy bolt passing through the end members and the cross-bar. The legs are pivoted to the inclined leg-supporting portions and therefore move from a splayed support position to a stored position alongside the cross-bar to be stable when erected but occupying minimum space when stored. An integral stop is provided for each leg and a gravity operated latch that locks automatically when the sawhorse is upright and unlocks automatically when the sawhorse is inverted. An additional support bar is provided pivotally mounted on two struts which can be supported at different heights in respective bores in the cross-bar. |
