Definitions

  • the base means may be constituted by sheet material, the protuberances being integral with and formed in one surface of said sheet material.
  • the markings may be produced under controlled conditions for achieving a high quality control which may be important in connection with particularly complicated shapes and distribution patterns of the protuberances.
  • At least one protuberance may be arranged in a recess in the surface of a kerb stone or a paving stone, said recess having a shape allowing light beams emitted by vehicular traffic to be retroreflected.
  • the insert may be protected from being scraped off by for instance a sweeping device or a snowplow while still being operational for all relevant light beams from the vehicular traffic.
  • Figs. 4-7 show partial cross sections of different embodiments of a protuberance according to the invention
  • Figs. 8-9 show partial cross section through further embodiments of the protuberances according to the invention.
  • Fig. 14 shows a front view of a section of a surface coating of a third embodi ⁇ ment of a kerb stone according to the invention
  • Figs. 28-30 show a front elevational view, a top planar view and a vertical cross sectional view, respectively, of a first embodiment of a sidewalk kerb stone of for instance concrete with protuberances according to the invention integrally moulded into the surface of the kerb stone,
  • Fig. 48 shows different combinations of various kerb stones according to the invention with pivoting elements according to the invention
  • Figs. 52-53 show a top planar view and a front elevational view, respectively, of an embodiment of a highway shoulder kerb stone with recesses at either end for receiving a discrete pivoting element having a protuberance insert glued to the top surface thereof.
  • the long distance light beams 13 and 14 are shown impinging on protuberances at points 15 and 16 a long distance L (e.g. 60m) in front of the vehicles.
  • the beams 13 and 14 are retroreflected to the eyes of the drivers 1 and 2 in the form of reflected beams 17 and 18, respectively.
  • the surface portions 40, 41 and 42 may have the same reflecting angle with respect to the subsurface, or said angles may vary according to the application.
  • the protuberances 35 may be of different height as described in connection with Fig. 9 so as to avoid shadows for the small angle light beams.
  • a kerb stone 50 of concrete or the like is arranged between a road pavement 51 and a sidewalk 52 in the usual manner.
  • the ex- posed face 53 and top surface 54 of the kerb stone 50 are provided with protuberances 55 having reflective surface portions with different reflective angles with respect to the plane of the road surface and/or a plane perpendicular to same.
  • a protuberance insert having a dome like body 73 with an annular flange 74 and slopes 75 provided with reflective surface portions 76 is embedded in a layer 78 of curable material adhered to a subsurface such as road asphalt.
  • the insert is anchored in the layer 78 by friction and adhesion with respect to the flange 74 at surface portions 77 thereof.
  • the embedding depth is controlled by the horizontal portion 79 between the dome 73 and the flange 74 as the resistance against downward movement into the layer 78 greatly increases when the portion 79 abuts the top of the layer 78. Adhesion forces between the underside of the portion 79 and the layer 78 will also add to the anchoring effect.
  • the protuberances may have any shape suitable for the purpose and may be constituted by ridges, wave-like projections, steps, shoulders and so on as long as the provision of reflective surface portions with different reflective angles with respect to the subsurface and/or a plane normal to the subsurface is allowed. Thus, they may for instance be inco ⁇ orated in the conventional pro ⁇ filed audio warning stripes for creating noise signals from a vehicle tyre rolling on the stripe.

Abstract

Structure de surface réfléchissant la lumière destinée à réfléchir des faisceaux lumineux provenant par exemple du trafic de véhicules sur une route, ladite structure comprenant des protubérances (35) disposées de manière individuelle ou selon un ensemble. Lesdites protubérances possèdent au moins deux parties (40, 41, 42) de surface réfléchissante présentant des angles différents par rapport à une direction donnée (37) et donc par rapport à un faisceau lumineux (36) donné. D'autres parties de surface réfléchissante présentant des angles différents par rapport à un plan de la surface inférieure supportant la structure de surface peuvent également être incorporées dans une protubérance (35). Lesdites protubérances (35) sont soit des pièces rapportées individuelles, soit des configurations d'un seul tenant avec une couche superficielle de la surface inférieure. Ladite structure de surface peut également être utilisée en tant que bordure de trottoir, pierre de pavage, barrière de route, panneau routier, enseigne publicitaire dans un stade et analogue.
