Formed sheet interlocking bracket and saw horse using such bracket
Abstract:
A saw horse comprises a pair of frames each assembled from a plurality of wooden struts joined by metal formings of sheet stock. Fabric hinges join the frames at their upper ends. The metal formings are positioned and closed around the beams with piercings engaging the fabric hinges. Spreader struts are also hinged by a fabric strap that permits the spreader struts to lay in horizontal positions when the frames are pulled into an A-shape, and to be oriented in side-by-side vertical positions when the frames are folded together.
