Abstract
Abstract The traffic delineator assembly of the present invention is comprised of a elongated resiliently flexible delineator member, an anchor post, and a rigid pilot plate. The pilot plate is attached at the upper end of the anchor post and the lower end of the flexible delineator member is attached to the pilot plate with its lower edge lying adjacent the lower edge of the pilot plate so that when the anchor post and pilot plate are driven into the ground or road surface, the bottom end of the delineator member follows the bottom edge of the pilot plate into the surface.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
123 words
A traffic delineator assembly comprising: a rigid anchor post drivable into the ground or roadway surface, a rigid pilot plate drivable into the roadway surface attached to an upper end of said anchor post; and an elongated flexible delineator member which is adapted to extend above the roadway surface attached to said pilot plate, the lower edge of said delineator lying generally adjacent to the lower edge of said pilot plate to follow said pilot plate into the roadway surface when said anchor post and said pilot plate are driven into the roadway surface, said delineator being sufficiently rigid to be unaffected by static conditions yet resiliently deformable to bend upon impact of a moving vehicle and spring back to an upright position.
Claim 2
Dependent Claim
123 words
A traffic delineator assembly comprising: a rigid anchor post drivable into the ground or roadway surface, a rigid pilot plate drivable into the roadway surface attached to an upper end of said anchor post; and an elongated flexible delineator member which is adapted to extend above the roadway surface attached to said pilot plate, the lower edge of said delineator lying generally adjacent to the lower edge of said pilot plate to follow said pilot plate into the roadway surface when said anchor post and said pilot plate are driven into the roadway surface, said delineator being sufficiently rigid to be unaffected by static conditions yet resiliently deformable to bend upon impact of a moving vehicle and spring back to an upright position.
