  • Patent number: 6199504
    Abstract: A soft sandwich board is disclosed, being formed utilizing a standard traffic cone. An ultraviolet stabilized nylon shroud is employed to simulate the two sides of a standard A-Stand sign system. The shroud is double sided, with an opening at its top for connection to the cone, and a concentric larger opening at its base for slipping over a square shaped cone weight connected adjacent the base of the cone. A Tee Cone Adapter and crossbar at the top of the cone provides for shaping the shroud into a pair of identical square or rectangularly shaped panels on which warning signs are imprinted, and reflecting strips are attached. Possible damage to vehicles or persons due to collision with these soft sandwich boards, or due to violent weather conditions blowing them about, is minimized.

  • Patent number: 5755174
    Abstract: A traffic safety control security system is described. Warning lights, signs, and warning flags are connected and secured to the tops of standard traffic cones either with or without the use of cone adapters. One end of a stainless steel aircraft cable connects directly to the traffic control accessories, while the other end of the cable is secured by a removable security disc and padlock within the traffic cone. Interconnecting the accessory and traffic cone together prevents injury to vehicles or individuals nearby if a traffic cone is accidentally struck by a vehicle, or encounters violent weather, causing the accessory to fly loose as a projectile. In addition a chain can now interconnect traffic cones in the system together, preventing theft of the traffic cones and/or accessories. Set up and knock down of the system is consistent with customary traffic safety control procedures.
