ABSTRACT:
A modular sign consists of an H-shaped metal frame. The pointed legs can be driven into the earth by stepping on the cross rail. Plastic side tubes are slid over the upper arms of the H. The tubes have slots cut through the side partway down from the top; the edges of a sign board are inserted into them. The top and bottom edges of the sign board are inserted into slots cut into the sides of a top and bottom tube, respectively. The ends of the top and bottom tubes are inserted into holes bored through the side tubes, which are of larger diameter than the top and bottom tubes. Thus the sign board's edges are completely covered by the tubes. For extra strength the top tube may be fastened to the side tubes at either end. For indoor use, the lower frame legs are slid into feet in the shape of an inverted T for stability.
