ABSTRACT:
A foldable traffic warning cone utilizes a first panel of generally fan shape having triangular faces joined at adjacent sides along face folding lines. The first panel has opposite free sides which interconnect to fold the first panel into an upright polygon. The triangular faces of the first panel have bottom ends with extending flaps which cooperate with a second panel having a number of sides commensurate to the number of faces on the first panel and which forms a base for the first panel. The second panel has wings extending outwardly from each of the sides and which are foldable to provide a wall extending about the base. The wings also trap the flaps and thereby connect the upright polygon and the base together. The warning cone can be selectively folded and unfolded for use and storage.
