  • Method and base for traffic channelizer
    Patent number: 5795530
    Abstract: A resilient and flexible base for a two-piece traffic channelizer is provided that does not require external ballasting to stabilize the channelizer against wind forces and vacuum forces created by passing vehicles and minor impacts from a vehicle. The base is formed of a hardenable liquid resin such that the base is resilient and flexible after curing and has a specific gravity greater than about 1.25. The base further includes at least one flexible footpad for generating a restoring moment when the channelizer is subjected to a tipping force, such as a minor impact. The composition of the liquid resin includes at least one off-grade polyvinylchloride (PVC) resin, a plasticizer and a specific gravity increasing agent. A method is also provided for forming the base by slush molding at least a portion of the hardenable liquid resin adjacent the interior surface of a molding cavity. The base formed by the disclosed method is also self-lubricating and resistant to chemical degradation and extreme temperatures.
    Type: Grant
    Filed: December 24, 1996
    Date of Patent: August 18, 1998
    Assignee: Radiator Specialty Company
    Inventors: Albert F. Monda, Milton Darrell Hinnant
