<p>The above-the-road housing portion 21 of a reflective road stud has a spherical contour rising gradually from the road in all directions and provides metal shoulders defining a divergent overturning light channel for retroreflectors 35. Bridges 45, 46 across the channel, from shoulder to shoulder protect the reflective lenses 34, from tyres and lift narrow two wheel vehicle tires up and over the lenses. A removable assembly retains the lenses 35 latched in place. Wash openings 41 directly above the lenses expose the lenses to direct impact by rain and reservoirs 76, 77 collect water for splash washing by tyre air blast. Bases for the reflectors can be surface mounted, imbedded for new road construction, or anchored by bolts in a shallow recess. A removable model has a permanently secured base below road level with a detachable upper housing locked in place by a metal wedge. <IMAGE></p> |
