ABSTRACT:
Two supporting elements of a stand for a display panel can either be opened-out and placed on the ground in the service position or folded-back when not in use. The ends of the two supporting elements are associated with a pivot on each side of the panel which is thus capable of rotating about a horizontal axis. Springs permit angular displacement of the panel to a horizontal position and serve to return the panel to a substantially vertical rest position. Potential applications of the device include portable traffic signs and advertising panels.
