发明名称 Sawhorse
摘要 A sawhorse apparatus which is sturdy and easily assembled or disassembled facilitating efficient storage and mobility. The invention is more sturdy than prior devices because it incorporates "cross beam support channel(s)" that extend down most or all of its length, providing rigidity in all directions. The invention employs two alternative embodiments. "Type A" features a single three sided channel that cradles the bottom of the cross beam and interfaces with a plurality support leg device using tapered dovetail or "T" rail groove joints. "Type B" features separate channel members, one attached to each end of the cross beam member and the combination extending along all or most of the cross beam length. The channel members are integrally molded to end pieces that provide sockets into which lumber support legs are inserted.
