Definitions

  • the present invention relates to a portable device for signalling emergency events on roads and the like, in particular in poor visibility condi­tions, in tunnels and during the night.
  • the main object of the present invention is to overcome the above mentioned draw­backs by providing a portable device for signalling emergency events on roads and the like, in particu­lar in poor visibility conditions, in tunnels and during the night, which is specifically adapted to provide to a driver of a motor vehicle a clear sig­nalling even under heavy foggy conditions and in tunnels.
  • a main object of the present invention is to provide such a portable device for signalling emergency events on roads and the like, which is adapted to provide the motor vehicle driver with the indication provided on a traffic sign corresponding to the en­forcing road code, in a clearly visible way, both during the night and in tunnels, even in the absence of illuminating devices and in foggy conditions.
  • Another object of the present invention is to provide such a portable signalling device which is very reliable in operation.
  • Yet another object of the present invention is to provide such a portable signalling device which can be easily handled and, moreover, can be obtained by using easily commercially available elements and materials.
  • Yet another object of the present invention is to provide such a portable device for signalling emergency events on roads and the like, in particular in poor visibility conditions, in tunnels and during the night which is very competitive from an economic and maintenance standpoint.
  • a portable device for signalling emergency events on roads and the like in particular in poor visibility conditions, in tunnels and during the night, said device being characterized in that it comprises a support member adapted to receive the terminal portions of a plura­lity of optical fibres adapted to provide at least a signalling pattern, said support member being coupled to a base housing a light source.
  • the portable device for signalling emergency events on roads and the like comprises a supporting base, over­ally indicated at the reference number 1.
  • This supporting base houses, in its inside, a light source which can be power supplied through a 12 V battery, or can be coupled to a possible power supply mains, through the interposition of a 220/12 V electrical transformer.
  • variable height tubular body 2 extends, which bears a support member, overally indicated at the reference number 3.
  • This embodiment provides a portable signalling device which can be easily handled and oriented, so as to afford the possibility of timely indicating emergency events.
  • the support member 3 is provided with a pannel 4, of any suitable shape, provided that it corres­ponds to those imposed by the enforcing road code.
  • the panel On at least a region of the panel, there are coupled the end portions of a plurality of optical fibres 5, adapted to provide a road indication, in conformity with the enforcing road code.
  • the signal emitted by the optical fibres which can be clearly detected at a great distance, must not be visible as the visible angle is greater than 12° so as to not provide any glare phenomena.
  • the bottom of the panel 4 is made starting from a light refracting type of film, indicated at the reference number 6, which is adapt­ed to improve the visual efficiency.
  • optical fibre signalling devices have a high brillancy, and, therefore, they can also be clearly seen under a heavy fog condition providing the driver with a perfect indication of the road path.
  • the light signal In the case of a very serious danger, it is possible to cause the light signal to be switched on and off so as to provide the driver with a clearly visible light signal.
  • a light intensity adjusting system could be also provided for adapting the optical fibre brillan­cy to the environment illumination thereby safely eliminating any glare phenomena.
  • optical fibres is such as to perfect­ly solve the problem of making road traffic signalling devices and signs, which can be clearly seen from a great distance and which do not cause any undesired glare phenomena for a motor vehicle driver, said devices having in the meanwhile a very reduced making and maintenance cost.
  • the signalling devices can also be mounted on service motor vehicles and can be power supplied from the same battery of the motor vehicle: thus, these signalling devices will provide a clear indication both of the service motor vehicle and of the path to be safely taken or any other sig­nals which can also be seen from both side of the road track.
