Definitions

  • This invention relates to reflective road markers, of the kind comprising an outer casing embedded, or to be embedded, in the surface of a roadway, a reflector unit, and resilient mounting means mounting the reflector unit in the outer casing, the reflector unit having an upstanding or protruding portion furnished with at least one reflective surface, normally lying above the road surface, and the reflector unit being movable up and down in the casing so that a vehicle tyre passing over the marker can depress the reflector unit against the resilient mounting means.
  • a road marker will be called in this description "a road marker of the kind hereinbefore specified”.
  • the reflector unit includes a pair of guard shoulders flanking the reflective surface or surfaces and forming part of the said upstanding portion; thus when a vehicle tyre passes over the marker, the shoulders are depressed also.
  • the guard shoulders preferably extend to a height at least as great as that of the reflective surfaces.
  • the road marker of this invention may be made in any suitable material, but can conveniently be made in the form of an assembly of injection-moulded plastics components.
  • the reflector unit of such a marker has a body consisting of a moulding which may include the guard shoulders integrally therewith.
  • the guard shoulders are preferably provided with suitable metal reinforcement, such as a stainless steel bar extending along and over the crest of each shoulder. Such reinforcement may be particularly desirable if non-rolling components of vehicles, such as snow-plough blades, are likely to be moving along close to the surface of a road in which the markers are installed.
  • the exposed light-receiving and light-transmitting surfaces of the reflector are inclined to the horizontal, they will be contacted by vehicle tyres. They are also well exposed to rain, and will be washed by the rain; but in dry weather, or at other times when there is not heavy rain (or even when there is) it is necessary to provide for cleaning of these surfaces, since they are exposed to mud, oil and other dirt, some of which is of a particularly tenacious nature.
  • the invention provides a road stud of the kind hereinbefore specified wherein the or each reflective surface is formed on one side of a reflector element whose opposite side is exposed to atmosphere, the reflector unit comprising a body member and one or more of these reflector elements sealed directly or indirectly on the exterior of the body member, so that the or each reflective surface is not exposed to the atmosphere, the resilient mounting means consisting of a ball of synthetic rubber or other suitable resilient material, and the reflector unit being supported on the ball.
  • the reflective surfaces are preferably formed on reflector elements which, in preferred embodiments of the invention, are mounted externally on the body of the reflector unit of the road marker. These elements are most typically flat, though they might for certain particular applications be suitably curved. The elements are so mounted that there is an enclosed air space behind each reflective surface.
  • the preferred arrangement involves paired reflectors, i.e. reflectors having their reflective surfaces arranged to deflect light in opposite directions (i.e. in two opposed, divergent beams) so as to be visible to vehicles travelling in either direction.
  • the reflective surface or surfaces may be so arranged, and be of such a number and/or shape, that light is reflected in more than these two directions, and may for example even be arranged to reflect light incident on the reflective surfaces from any direction around the marker.
  • the grooves 29 terminate at their lower ends in a downwardly-facing stop shoulder 30, so that, as shown in Figure 2 in full lines, the stop shoulders 28, 30 abut against each other when the reflector unit is in its normal or upper position, in which a flat upper surface 31 of the reflector unit body lies flush with the flat upper surface 17 of the outer casing. In this normal position the whole of the lantern 13 lies, of course, above the surface 23 of the road.
  • the reflector unit body 25 is preferably injection-moulded in a single piece from a suitable synthetic plastics material having a high impact resistance.
  • a preferred material is polycarbonate.
  • the reflector unit body 25 is made by moulding it around the insert body 39, so that the lugs 42 and flank portions 41 of the latter are embedded firmly in the body 25, as seen in Figures 2 and 3 respectively.
  • the flank portions 41 form the cores of two lateral guard shoulders 45, which flank the ramp-like portions 40 and which are reinforced by the guard bars 43.
  • the guard bars are preferably exposed at the top, along the greater part of their length, but without protruding significantly above the shoulders 45.
  • the underside of the insert body 39 is preferably strengthened by means of integral ribs such as the longitudinal ribs 46, embedded into strengthening ribs 47 of the reflector unit body 25.
  • Each of the two reflectors 14 is in the form of a flat element whose rear or reflective surface 48 is of the conventional "corner-cube" type.
  • the front, light-transmitting and light-receiving surface 49 is smooth and flat.
  • the reflectors 14 are fixed indirectly to the exterior of the reflector unit body 25 by being secured to the insert body 39.
  • each reflector lies over, and parallel to, the corresponding ramp-like portions 40 of the insert body, the reflector having a peripheral spacing bead 50 lying upon the surface 40, so that there is an enclosed (i.e. sealed) air gap 51 immediately behind the reflective surface 48.
  • Each reflector 14 is secured around its entire periphery to the insert body 39 and shoulders 45 by ultrasonic welding.
