  • Patent number: 6234712
    Abstract: A snowplowable pavement marker includes a frame member having primary spaced keel members with ramp surfaces which have upwardly inclined contours beginning at a forward end portion of each keel member and extending at a first acute angle, then transitioning to a second portion having a second acute angle which is greater than the first angle. Further, the frame member includes an auxiliary keel member having ramp surfaces disposed between the primary keel members and having the same contour as the primary ramp surfaces. The auxiliary keel member ramp surfaces extend inwardly of the frame member to a point proximate the marker's reflector and serve to prevent damage by a snowplow blade set at a wide angle to the direction of blade travel. Advantageously, the contour of ramp surfaces permits a higher frame member installation above the pavement and allows for greater exposure of the reflector.
