Definitions

  • cats eye type units which are placed into the road and reflect light from vehicle headlights, to guide drivers to follow the road line safely. These are solid devices, and while they are proven to work, are very expensive to maintain and replace when removed (aka "popped") from the road by traffic wear and tear- and especially in snow prone regions by snow plough blades. Very often complete stretches of road are left without cats-eye cover when they are "popped" due to the expense of replacement.
  • This invention seeks to provide a very cheap solution to this problem; providing a light reflector, particularly for use on roadways, and seeks to provide a very low cost, very low profile, easily replaced solution to this problem.
  • the dome-shaped base member in cross-section inclines upwards (with concave edges) and then rounds off at the top with a minimum top surface area to reduce contact with road tyres and snow plough blades.
  • the attachment to the road surface is made easily and cheaply by the use of thin membrane "tabs" integrally moulded to each side of the cats eye base, and which extends either side of the main body of the road stud.
  • the extent of the tab may vary from tabs on two sides, through to a circular tab, encircling the central road stud.
  • the material will be high visibility allowed by local regulations, preferably day-glow for maximum visibility in poor visibility, such as mist and fog, to provide best safety road vision whenever possible.
  • a very high visibility marine grade reflector is contained within a very low profile, highly visible (day-glow) "jelly type" base, made of a material. This may be silicon rubber, perhaps rubber or plastic, designed to be below snow blade height, but to flex and "give in” to the forces acting on it in the rare event that it does become an obstacle. After lateral forces have passed over the base unit and compressed it, the base material will revert (spring) back to it's original shape, and continue to present the high visibility reflector as a safety aid.
  • the design uses "tabs" encircling the road stud. This can perhaps make use of wings on either side of the road stud, and using permutations of perforated membrane, can be extended to a full membrane encircling the entire road stud.
  • the membrane is embedded within tarmac which acts as a compressible sandwich, keeping the road stud under white lines or under tarmac, and reduces the risk of the road stud unit being sprung out.

Abstract

L'invention a pour but de rendre le produit plus robuste que les plots rétroréfléchissants provisoires et suffisamment robuste pour être utilisé sur les routes américaines et canadiennes enneigées. Dans le cas où le plot rétroréfléchissant est retiré de la surface de la route, il est possible de le remplacer immédiatement sans engendrer de coûts et d'obtenir une plus grande couverture de sécurité de la route. Le plot rétroréfléchissant peut également être fabriqué avec un matériau recyclé.
