发明名称 Self-righting warning marker
摘要 A self-righting warning marker includes a base having a warning sign attached thereto and projecting upwardly therefrom. The warning sign is preferably formed of a polymer which is rigid yet resilient and flexible, to prevent breakage upon contact from a vehicle or the like. The base of the marker has a pivot surface extending between a rearward face and a bottom surface so that the marker will roll along the pivot surface from an upright orientation to a horizontal orientation if contacted by a vehicle. A ballast weight within the base is located such that the center of gravity of the marker is located forwardly of the pivot surface to thereby cause the marker to be self-righting. In a preferred embodiment of the invention, an illuminator is mounted on the marker, with a lens attached along an upper edge of the warning sign and a bundle of fiber optic cables extending through the panel of the warning sign to a power source in the base which includes a light and a battery.
