Definitions
- the present invention concerns road signs having high refractive power.
- the road signs painted on the roadway include transversal, longitudinal signs and other signs.
- the transversal and longitudinal signs 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. It particular it is established that the traffic signs 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 togethere 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. On the other hand, with 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.
- the purpose of the present invention is to propose a road signs painted on the road surface having high refractive power also in bad environment conditions and which maintain this particular efficacy for a long time.
- Such a purpose is reached through signalling stripes, executed on the roadway with paint, or similar material having the same efficacy, characterized in that they comprise reflectors or similar refracting objects partly mixed in said paint or similar material at distances and with variable inclinations according to the type of roadway, the kind of signals or other, in such a way to reflect the luminous rays incident over it in the direction of coming of the vehicles on said roadway.
- Figure 1 shows a stretch of the signalling stripe according to the invention, seen from the above;
- Figure 2 shows a view in section, realized according to the line II - II , of the stripe shown in figure 1;
- Figure 3 shows an enlarged transversal part of the signalling stripe of figure 1;
- Figure 4 shows an enlarged view in section, realized according to the line IV - IV of figure 3;
- Figure 5 shows a view from the above of a second example of realization of a signalling stripe according to the invention
- Figure 6 shows a view from the above of a third example of realization of a signalling stripe according to the invention.
- Figure 7 shows a different execution of the signalling stripe of figure 1;
- Figure 8 shows an enlarged part of the signalling stripe shown in figure 7;
- Figure 9 shows a further example of realization of a signalling stripe according to the invention, made transversally on the roadway instead of lengthwise like for examples shown in the figures from 1 to 8.
- the stripe 10 represents a continuous stripe made with a yellow coloured paint, used to signal the border of the roadway, or to mark this one from the adjacent cycle tracks, from the sidewalks, from the laybies.
- the reflector 14 is formed by a biconvex spherical lens between two concentric surfaces 15 and 16, bent in such way that any incident ray over the benter surface, 15, reflects itself over the other surface, 16, which is silver, in such way to come back exactly to the going direction.
- the middle axis 17 of the reflector 14 is properly inclined up in such way that the angle of refraction of the reflector specified by the two lines, 18 and 19, passing through the common centre of bending 20 of the surfaces 15 and 16, affects the zone over the roadway 11.
- the invention should be applied in situations where the road traffic runs only on a side of the signalling stripe, then it should be more useful to turn to the solution shown in figure 5, where one can note that the best position of the reflective angle of the reflectors is obtained not by the simple inclination of the reflectors themselves with respect to the stripe 10; in fact, it might be more immediate, and so cheaper, to put, during the realization of the stripe, the projections in an inclined position on it than to put each reflector in an inclined position on the projections 13.
- FIG. 6 A further example of these applications is shown in figure 6, in which we can see that the projections 13 are put on the stripe 10 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 the sides and with better efficacy of the 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 13 above described.
- the placing of the reflectors 14 into the material forming said projections 22 is made or 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 entring areas to 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 13, would be and they might contain a good whole of refracting reflectors according to the invention and in the meantime they would be a barrier of small obstacles useful to warn the driver when he gets over them.
- pratical embodiment of the present invention can be realized besides those above described.
- This signalling system is very effective thanks to the use of devices with a great refracting power like the reflectors; moreover, it has the ability to maintain for a long time the 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 an economic cost of production compared with the signalling system in which are used projections or bulbs in a different material from the one used for the stripes.
- the high of the projections can be varied; in fact, the real dimensions of the reflectors can be inferior to the ones of the reflector-14 illustrated in figure 4, here enlarged to show it well.
- the numbers of the reflectors, or the similar refracting objects having equal efficacy can be inferior or superior to the ones of the shown examples according to the applications and the environment in which they are put.
- the distance also between the projections which contain the above refracting objects can be varied so that it can clearly indicates the presence of the signalling stripe in any environment condition and whatever the speed of the vehicle which is going along the roadway may be.
- 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 less obstacle to the road traffic which on the contrary, derives from the existing methods.
