Abstract
A road marker (10) comprising a body (12) extruded from a non-resilient material is disclosed and claimed. The marker body comprises a sloping wide base (14), a neck (18) and a head (16) and is generally I-shaped in transverse cross section. The cross-sectional area of the neck (18) on line A is less than that of the head (16) and that of base (14) in parallel planes.
Claims8
A rigid road marker adapted to be mounted to a road surface, the road marker comprising:
- a base having a bottom surface and an upper surface;
- a neck extending from a region of the upper surface of the base towards a head;
- the base, the neck and the head being integrally formed by an extrusion process;
- the neck being of sloping configuration in that at least one of two opposed side faces thereof slants from a wide lower region of the neck immediately adjacent the upper surface of the base to a narrower upper region of the neck immediately adjacent the head;
- the head comprising an overhanging surface facing the base and at least partially overhanging said at least one of said two opposed side faces;
- reflector means mounted on the body immediately adjacent said at least one of said two opposed side faces of the neck, between said overhanging surface and the upper surface of the base;
- the cross sectional area of the wide lower region of the neck being less than 30% of that of the bottom surface of the base, and the cross sectional area of the head being less than 25% of that of the bottom surface of the base, to thereby minimize rocking of the road marker on the road surface.

A body for a road marker adapted to be mounted to a road surface the body for the road marker comprising:
- a base having a bottom surface and an upper surface;
- a neck extending from a region of the upper surface of the base towards a head;
- the base, the neck and the head being integrally formed by an extrusion process;
- the neck being of sloping configuration in that at least one of two opposed side faces thereof slants from a wide lower region of the neck immediately adjacent the upper surface of the base to a narrow upper region of the neck immediately adjacent the head;
- the head comprising an overhanging surface facing the base and at least partially overhanging said at least one of said two opposed side faces;
- the upper surface of the base and the overhanging surface of the head providing opposed formations for receiving reflector means immediately adjacent said at least one of said two opposed side faces of the neck;
- the cross sectional area of the wide lower region of the neck being less than 30% of that of the upper surface of the base;
- and the surface area of the head being less than 25% of that of the bottom surface of the base, to thereby minimize rocking of the road marker on the road surface.
