Abstract: A lane marker includes a base, an illuminator, and a frangible bracket resably holding the illuminator in the lowered position on the base. A cantilever embedded in the bracket extends therefrom along the illuminator and is stronger than the bracket. The marker also includes a vertically expandable spring whose coils are compressed in a planar array against the base, one section of the spring biasing the illuminator to swing up from the lowered position. A keeper section of the spring connects to the illuminator and bears on the coils to keep them compressed against the base. An end of the keeper section latches to the base until the frangible bracket is broken. When the bracket breaks, the spring swings up the keeper section along with the illuminator so as to free the keeper section's end from the base.

Abstract: A temporary roadway marker having an L-shape that includes a base adapted to be attached to the roadway surface and an upwardly extending leg on which a reflective strip may be mounted is disclosed. The body of the roadway marker is formed of two materials having different flexural moduli, thus allowing the upper portion of the roadway marker to be formed of a material having a flexural modulus similar to that of the reflective strip. This helps to prevent stress concentration in the interface in between the reflective strip and the upper portion of the roadway marker, thus reducing cracks and failure of the reflective strip. In addition, it allows the base and the transition between the base and the upwardly extending leg to be formed of a more flexible material, which allows better flexing without breakage and the base to conform to the roadway surface.

Abstract: Marker devices, each comprising a base with an upright post thereon, are molded from an elastomeric material.
