The pylon has a cane mounted on a base. The cone telescopes from an open position in which the cone tapers upwardly to a closed position in which the cone is substantially flat. The cone is hollow and a coil spring within the cone biases the cone open. There is a lock for selectively locking the cone closed for storage when the cone is not in use.
