Definitions

  • This invention generally relates to prefabricated, light-reflecting, horizontal roadway marking strips and more specifically is concerned with the problem of resistance to the scraping action of mechanical, snow-clearing equipment - such as snow-plows.
  • the rails described in forementioned patent applications 22352 A/76 and 30886 A/76 are replaced by protruding elements which are appropriately spaced along the marking strip so as to take advantage of the snow plow's kinetic energy and rebound hysteresis and cause the plow blade to bounce from one protruding element to the next, thus avoiding - within practical limits - any damage being caused to the optical elements by the passing plow blade.
  • the protruding elements can be button-shaped, lozenge-shaped or have any other kind of appropriate shape and have a rectangular or a rounded, convexed cross-section. They can either be lined up in straight rows on the marking strip or be staggered.
  • the light-reflecting or retroreflecting elements hereafter also referred to as retroreflecting pearls or, more generally, as optical elements, can also be mounted onto the protruding elements themselves.
  • the protruding elements are also intended for use as lift points when desiring to remove the installed marking strips from the installed location on the roadway surface.
  • This invention also regards the method of manufacturing protruding elements, the method of manufacturing the basic strip and the relative completed marking strip.
  • Fig. 1 shows a portion of a strip or tape-like road marking material 1, with protruding elements 2 lined up in several rows.
  • At 5 there are shown schematically retroreflective optical elements for visibility of the marking under the light emitted from the vehicle headlights../.
  • These optical elements are shown in an exemplary schematic manner only and may be of any of the various well known constructions for this purpose.
  • Protruding elements initially having a rectangular cross-section - regardless of their outer shape - will cause the snow-plow blade to make an inclined angle with the surface of the protruding elements and thus act as a cutting tool on the elements which thereby will increasingly adopt a ramp-like shape in the direction of forward travel of the snow plow equipment.
  • Figure 2a shows the cross-section of the protruding element 2'when new
  • Fig. 2b shows the same cross-section 2" after the snow-plow blade has made several passes over it.
  • protruding elements are made of a material having exceptional mechanical properties, which includes such materials as thermoplastic polyurethane, shock-resistant polymethacrylate and polycarbonate.
  • the protruding elements 2 can also have retroreflective pearls mounted on them, covering the tops and sides.
  • Fig. 3 shows an embodiment of this type with a disk-shaped protruding element 2 being covered on the top and sides with the aforementioned pearls 4.
  • Fig. 4 shows a method for producing these disk-shaped protruding elements, starting with an extruded, solid cylinder (10). Upon being extruded, the cylinder is sprayed (12) with a bonding substance and then with appropriately-sized retroreflective pearls (14). The disks are then cut (16) to the desired thickness.
  • protruding elements having a rounded or convex cross-section which permits a more uniform bouncing action of the plow blade.
  • This type of protruding elements can be produced by either injection or compression molding, but are most economically produced by extrusion through die rollers.
  • Fig. 5 in its lower portion shows a protruding element of this type in convex cross-section (18), and in its upper or main portion shows a method of production for such elements, using counter-rotating cylinders (20' and 20") located downstream the extrusion head (22). This method of production is completely analogous to the one described in the issued US Patent No. 4,072,403. Particular reference is made to Fig. 5 of this patent.
  • the best way of applying the protruding elements to the marking strip is to use the same method used for applying the optical elements. After the basic support strip has been coated with a bonding liquid, and before the liquid has had a chance to harden, the protruding elements are appropriately located on the marking strip. Both the bonding liquid and the protruding elements are best made of polyurethane.
  • thermoplastic polyurethane The temperature of the impregnating, thermoplastic polyurethane is compatible with that of the thermoplastic bituminous primers, as described, for example, in issued US Patent No. 4,102,718.
  • the protruding elements may be also applied to the marking strip by suitably laying down a "hot melt” (thermofusible) adhesive, followed by the positioning on same of the protruding elements.
  • a hot melt thermoofusible
  • the protruding elements can be used for facilitating the lifting of the marking strip from its installed position, if removal of the tape is desired.
  • the protruding elements in fact, constitute attachment points for effecting removal of the marking strip.
