Patent ID: 8164483

Claim:
A portable signal system configured to operate by remotely transmitted control signals and having an adjustable frontal profile for managing advancing motorists in roadway traffic wherein said system comprises: a substantially vertical stanchion with a base, said stanchion further defined as including an upper portion and a lower portion with said stanchion lower portion affixed to said base; said stanchion upper portion including at least one warning light signal element disposed on a first side thereof, the at least one warning light signal element forming a warning light section of said stanchion upper portion and disposed so as to face in a first signaling direction; pivot bracket elements affixed to said stanchion above said base; journalled on said pivot bracket elements are proximate ends of a pair of articulated arms constrained for swiveled movement between a folded position wherein distal ends of said arms are disposed relatively adjacent to each other and generally along said first signaling direction defining a first frontal profile width of said portable signal system in said first signaling direction, and an extended position wherein distal ends of said arms are extended substantially away from each other in a direction substantially perpendicular to said first signaling direction and generally defining a second frontal profile width of said portable signal system significantly greater than said first frontal profile width; affixed at each of said distal ends of said arms is a stop signal sign oriented to face generally perpendicular to said first signaling direction when said arms are swiveled to said folded position, and to face generally in said first signaling direction when said arms are swiveled to said extended position; each said stop signal sign including at least one stopping light element mounted thereon so as to face in said first signaling direction when said arms are swiveled to said extended position; a control unit affixed to said stanchion, wherein said control unit includes therein a power source for energizing said at least one warning light signal element, said at least one stopping light element, and said swiveled movement of said pair of articulated arms; a receiver for said remotely transmitted control signals and having at least one receiver switch for selectively activating said energizing of said at least one warning light signal element, said at least one stopping light element, and said swiveled movement of said pair of articulated arms in response to said transmitted control signals; whereby said portable signal system can be positioned along a roadway with said stanchion first side facing in said signaling direction opposing oncoming traffic, wherein said stop signal signs are un-viewable by said advancing motorists in said oncoming traffic when said articulated arms are in said folded position and fully viewable by said advancing motorists in said oncoming traffic when said arms are in said extended position.
