  • System for mounting billboards
    Patent number: 5588237
    Abstract: A device for temporarily mounting a billboard to an exterior surface on a vehicle utilizes a rectangular frame for supporting the billboard and a pair of vacuum cups for attaching the frame to the side of the vehicle. The vacuum cups are provided with a pumping mechanism for creating a substantially leak-proof seal against the surface of the vehicle and for thus preventing unintended detachment of the sign from the surface.
