Work support

Abstract

A one piece frame or channel for a work support which is usable during building or construction principally as a support at ground level or as a scaffold at elevated levels regardless of whether the surface is even, irregular or constitutes different heights. The channel is used in pairs to form the work support. A plurality of legs are conveniently made from two-by-fours which are clamped to the channel at a suitable height in conformance with the ground so as to set the plank horizontally which plank extends across the pair of laterally spaced channels. Top brackets are interlocked in the top portion of the channels to engage and to hold the plank in assembled position. A clamp is carried on leg portions of the channel on an axle journaled in punched support lugs. A spring biases the clamp to engage the legs. Teeth are formed on the clamp to secure the legs in adjusted position. The channel has a base at its inner side formed with a radius at the edges thereof which turn out into flanges, which radius co-acts with the clamp to wedge-lock the right angled edges of the leg thereagainst. Lock tabs are formed on the top brackets to freely slide within outturned support flanges of the channel to permit adjustment of the top brackets prior to their being bolted in assembled position. When disassembled the top brackets can be stored within the top portion of the channel.
