Abstract (en)
A road marker for embedding in a road surface (23) has a displaceable reflector unit (11) resiliently carried in a cup-shaped casing (10) on a spherical rubber spring (12). The reflector unit (11) carries uppermost a pair of oppositely-facing reflective elements (14) disposed back-to-back and inclined at low angles to the horizontal. The reflective elements (14), in the upper biassed position of the reflector unit (11), protrude above the upper rim (17) of the casing (10). A pair of guard shoulders (45) disposed on the reflector unit (11) flank the pair of reflective elements (14), and protrude above adjacent parts of those elements (14), so that when a vehicle tyre rolls over the marker, depression of the shoulders (45) by the tyre displaces the reflective elements (14) away from the tyre and thereby reduces the extent or degree of physical contact of the tyre with the exposed surfaces of the reflective elements (14). The shoulders (45) preferably incorporate metal reinforcement members to protect the shoulders (45) against non-rolling oblects which slide over the marker, and the reflector unit (11) has apertures through which jets of air/water are expelled from the casing (10) when the reflector unit (11) is depressed by a tyre.
