Abstract: A portable traffic signalling device comprises a frame on wheels which supports an enclosed occupant compartment arranged to receive an occupant therein. The compartment is pivotal on the frame between an upright deployed position and a transport position lower in elevation than the deployed position. A traffic indicator is supported on the frame for directing vehicular traffic as controlled by the occupant of the compartment. The device permits a human operator to judge how to direct traffic within a safe environment. The use of a portable compartment with traffic indicators is safer than use of conventional flagpersons to temporarily direct traffic as the occupant of the device is less likely to be subject to fatigue and the like.

Abstract: A condensed retractable traffic cone is a device designed to provide motorists with advance warning of disabled vehicles and/or work zone areas. The device has been designed to withstand reasonable winds through the use of two base supports, a lower portion, a retractable arm and a series of retractable vertical risers. The retractable vertical risers in combination with a retractable arm allow for the device to easily expand to height consistent with traffic engineering design standards when in operation and then compact when it is in storage. The two base supports are designed not only to provide the necessary structural stability but to also open and close about the retractable vertical risers thus providing for additional compactness. The vertical risers are designed with flexible hinges so that they may store flat and expand to a rectangular shape when the base supports are rotated to an open position. This is accomplished a by linkage connecting the lower vertical riser and the base supports.
