  • Patent number: 4848958
    Abstract: A deflecting rod reflector is designed for snow removal equipment areas. A cubically formed substantially pentagonally shaped rotatable deflecting reflector is housed in a hollow housing having an opened top and a semi-circular bottom. The housing is recessed flush into a road surface. The reflector can be deflected in two directions by car tires or snow plough blades, and while in the process of deflecting, will eject debris from the interior of the housing. Biasing springs attaching axle pins on the reflector support member to gudgeons in the side walls of the housing return the reflector support member back to a vertical position after the car or snow plow has moved on. The invention can be quickly and easily installed as a one piece unit in road recessions manufactured by equipment already used by California and other road maintenance services.
