Definitions

  • the present invention relates to a variable message optic fibre signalling device, which has been particularly designed for traffic signs.
  • optic fibre sign strictlyalling devices which are used as traffic signs or other signalling boards or light panels, as used in very different fields.
  • optic fibre light panels have been generally made exclusively for not modifiable messages.
  • the aim of the present inven­tion is to overcome the above mentioned drawbacks, by providing an optic fibre variable message signalling device, specifically designed for traffic signs, which is able of changing, in a quick and easy way, the message to be presented on a panel, without affecting the optic fibres or their arrangement.
  • a main object of the present invention is to pro­ vide such an optic fibre signalling device which affords the possibility of modifying the message by simply modi­fying a middle panel which is not directly coupled to the optic fibres.
  • Another object of the present invention is to provide such an optic fibre variable message signal­ling device which is very reliable in operation.
  • Yet another object of the present invention is to provide such an optic fibre variable message sign­alling device which can be easily made starting from easily available elements and materials and which, more­over, is advantageous from a mere economic standpoint.
  • an optic fibre variable message signalling device particularly designed for traffic signs, characterized in that said signalling device comprises a first plurality of optic fibres, arranged between at least a light source and a first intermediate panel, arranged with a facing and spaced relationship with respect to a second intermediate panel, from said second intermediate panel a second plurality of optic fibres extending which are coupled to an outer panel, between said intermediate panels there being provided a shutter element adapted to modi­fy the message on said outer panel.
  • the optic fibre variable message signal­ ling device particularly for traffic signs according to the invention, comprises a first plurality of optic fibres, indicated at the reference number 1, which ex­tend from a light collector element 2, adapted to cause the light beam emitted from two light sources 3 to converge.
  • the optic fibres 1 are caused to pass through holes 10 which are formed through a first intermediate or middle panel 11.
  • a second interme­diate panel 12 Facing the first intermediate panel 11 and spaced therefrom there is provided a second interme­diate panel 12, which also includes throughgoing holes having an arrangement which corresponds to that of the holes 10 formed through the first panel 11.
  • a shutter element 20 also of plate-like shape which is provided with a plurality of throughgoing holes sets.
  • the shutter element 20 is driven by a linear actuator 21 which affords the possibility of obtaining a given number of desired patterns.
  • the shutter element 20 can assume eight different positions between the panels.
  • the disclosed arrangement is accordingly such as to quickly modify the light message display­ed on the panel, without the need of modifying the connections of the optic fibres which are always coup­led at the same points and which will transmit a dif­ ferent message depending on the position of the shutter element arranged between the intermediate panels.
  • the men­tioned shutter element practically operates as a dia­phragm, allowing for light to pass through some regions, corresponding to the throughgoing holes, while prevent­ing light from passing through the dark regions, there­by quickly and easily changing the message being dis­played, and which has been overally indicated at the reference number 30 in the accompanying drawings.
  • the signalling device according to the in­vention is very simple construction-wise since it, by using a simple shutter element which can be arranged at different positions, affords the possibility of easily changing the message being displayed without modifying the interconnections of the optic fibres.
  • Another important feature of the invention is that two light sources have been pro­vided for a very reliable operation of the signalling device.
