Patent ID: 7037033

Claim:
A one piece reflective roadway marker comprising: an upper resilient segment having an interior planar surface with raised, beaded periphery edges and a plurality of cube-corner reflective elements; a lower rigid body segment having a top planar portion, one inclined reflective face, two arcuate sides, a planar base surface and a backside forming a perpendicular angle with respect to said base surface, said backside can be provided with thin ties for interlocking with the backside of a second marker; a plurality of cube corner reflective elements within the interior of designated cell like areas within said inclined reflective face of the lower rigid body segment; and a plurality of walls for partition and structural support within said lower rigid body segment, said walls disposed rearward starting at the periphery of said designated interior cell like surfaces of the reflective face, thereby defining multiple hollow cavity air gaps beneath said cube corner reflective elements, said hollow cavity air gaps each having a centerline that form an angle of about 80 to 120 degrees with respect to the corresponding outside planar reflective face, said hollow cavity air gaps having one row of open ends at the planar base surface and an upper row of open ends at the vertical backside of said lower body.
