Abstract: The present invention relates to a collapsable frame for a sign, for example, those used in road construction and repair. The sign frame is adapted to be unfolded from a collapsed position to a display position with releasable locking means to hold the frame in the display position. The present invention also comprises optional releasable resilient locking means, such as a spring, to hold the frame in the display position while allowing it to give slightly in wind and weather.

Abstract: The versatile all purpose barricade structures of this invention include a portable road sign unit which utilizes a triangular brace member or support bracket and collapsible legs with ring means for locking them in place. Hollow legs are utilized in connection with plugs which enable the legs to be repaired on the job when necessary. The legs may also be internally loaded so that the use of sand bags and the like is unnecessary. The structures include a tape unit which may be quickly and conveniently put in operating position. The structures also include a slidable barricade panel which may be used in connection with separate leg units. The support bracket and associated leg units may be a separate item which slidably receives a barricade panel of any length, or the bracket and legs may be permanently affixed to a barricade panel. The barricade panel may also be stood on end to serve as an upright, elongated light or flag holder.
