Abstract
A collapsible portable sign is described having a pair of vertically disposed parallel laterally spaced apart legs connected together at their upper ends by means of a center piece, all of which can be formed from metal or plastic tubing. The legs are releasably connected to the center piece as by means of pivots or removable socket connections enabling the legs to be folded parallel to the center piece for compact storage. A movable support bar extends between the legs when the sign is erect and a flexible sheet of cloth (e.g., nylon cloth) or plastic is supported between the center piece and the support bar to provide a display surface having information printed thereon.
