Definitions

  • the present invention concerns road markers having high refractive power.
  • the road markers painted an the roadway include transversal, longitudinal markers and other markers.
  • the transversal and longitudinal markers consist of discontinuous and continuous stripes made with paint or other materials having the same efficacy; they must have such features to be well visible both by day and at night.
  • the traffic markers painted on the road surface which have to be visible during the night, must be refracting; to achieve such a purpose two different techniques are today employed, both using glass microballs which are premixed together- with the paint or are sprayed on the wet painted stripes.
  • the former of the said techniques is more economic than the latter but it does not offer the same efficacy; in fact the microballs come up on the surface of the stripes, only by degrees in the long run, owing to the continuous abrasive action of the road traffic.
  • the technique of the spray painting of the microballs not only one has to support high costs but moreover the efficacy lowers rapidly because of the inevitable continuous removal of the microballs.
  • US-A-4 069 281 describes a roadway surface marking strip material having a base layer and an upper layer, wherein said upper layer comprises an upper face which forms the marked area and has a number of protuberances spaced lengthwise of the strip material and a plurality of retroreflective elements secured to ends seated on said traffic contactable upper face, providing in this way both nighttime visibility and non-skid properties to said marked area.
  • the object of the present invention is to propose a road markers painted on the road surface having high refractive power also in bad environment conditions and which maintain this particular efficacy for a long time.
  • the stripe I0 represents a continuous stripe made with a yellow coloured paint, used to signal the border of the roadway, or to detect this one from the adjacent cycle tracks, from the sidewalks, from the laybies.
  • the reflector I4 is formed by a biconvex spherical lens between two concentric surfaces I5 and I6, bent in such a way that any incident luminous ray over the benter surface, I5, reflects itself over the other surface, I6, which is silvered, in such a way as to be reflected into the direction of the incident ray.
  • the middle axis I7 of the reflector I4 is properly inclined up in such a way that the angle of refraction of the reflector specified by the two lines, I8 and I9, passing through the common centre of bending 20 of the surfaces I5 and I6, effects the zone over the roadway II.
  • FIG. 6 A further example of these applications is shown in figure 6, in which we can see that the projections I3 are put on the stripe I0 in turn in a perpendicolar position and in an inclined one with respect to the direction of the stripes; such a disposition might be useful, for example, in the motor-way signalling system to signal the right margin of all the gangways for the usual road traffic, said margin being delimitated by a yellow coloured continuous stripe and forming a boundary for a further emergency gangway situated at the right of said stripe which, for this reason, has to be visible from both sides and with better efficacy from side where the road traffic usually runs.
  • FIG. 7 refers to the possibility to mix the reflectors, or the similar refracting objects, with the projections, 22, having a shape of half-spheres and disposed along the stripes 23 and 24; said projections 22 being made up with paint, or similar material, when the stripe is painted or preliminarly, like for the projections I3 above described.
  • the displacing of the reflectors I4 into the material forming said projections 22 is made either when the stripe has being executed or when the projections themselves 22 are being produced.
  • spherical bowl projections 22 are situated near the cross-roads where there is no right of precedence and however they are situated where vehicles must stop, like in the entry areas of the motor-ways.
  • Some projections 22, along the stripe, even if at regular intervals, would not be a great obstacle to the road traffic as some continuous projections, like projections I3, are and they might contain a good whole of refracting reflectors according to the invention; in the meantime they would be a barrier of small obstacles useful to warn the driver when he gets over them.
  • This signalling system is very effective thanks to the use of items with a great refracting power like the reflectors; moreover, it is capable of maintaining for a long time said efficacy thanks to the fact that the reflectors themselves are well mixed up in the paint which constitues the signal stripes; for this reason, we can have a low cost of production compared with the signalling system in which projections or bulbs are used in a different material from the one used for the stripes.
  • the height of the projections can be varied; in fact, the real dimensions of the reflectors can be smaller to the ones of the reflector-I4 illustrated in figure 4, which is here enlarged to better show it.
  • the numbers of the reflectors, or the similar refracting objects having equal efficacy can be smaller or larger than the ones of the shown examples according to the applications and the environment in which they are put.
  • the distance between the projections which contain the above refracting objects can also be varied so that it can clearly indicate the presence of the signal stripe in any environmental condition and whatever the speed of the vehicle which is going along the roadway, is.
  • a further advantage derived from the technique of the present invention is the swiftness to execute the stripes with the refracting objects and so the smaller obstacle to the road traffic which, on the contrary, derives from the existing methods.
