Abstract
A work-supporting device such as a sawhorse that is light and strong and which can be easily assembled and knocked down into a compact form without requiring any screws, bolts, clamps or similar fastening devices. The sawhorse has a cross beam with vertical, rectangular, hollow recesses extending from its bottom side into which at least two pairs of legs may be inserted. The legs are shaped so as to provide a wedging fit within the recesses and an interlock is also provided between the legs and the cross beam so that the legs remain securely in place, although they can be readily inserted and removed. The sawhorse preferably is made from a structural foam thermoplastic material having sufficient strength that the sawhorse is capable of supporting heavy loads. The material will not rot, splinter, warp or rust. The legs may be arranged to support horizontal shelves if desired and the cross beam into which the legs are inserted may be made in different shapes to suit different purposes, for example, to constitute a sawbuck.
