  • the device may include a block or element made of semi-rigid composite (polyurethane or other) translucent hollowed out, molded in the shape of a paver, border or other depending on the adaptation and tinted in the mass.
  • This block is connected to a light generator by a fiber cable optical.
  • This light block is sealed or glued and is part of a together at the edge or across a road or pedestrian.
  • a device may include hollow elements in translucent composite flexible material (polyurethane or polyester), tinted (orange) in the mass, fixed by metal legs on or to the inside of the safety barriers or barriers and supplied by fiber optic cables attached behind the slide or barrier security ; this optical fiber carrying only light, does not presents no electrical risk in the event of an impact with the obstacle.
  • optical fibers are inserted inside the composite block in a cavity provided for this purpose and protecting the end of the fiber optics for dirt, shocks, humidity and contacts accidental with hot materials usually used when manufacture of track coverings such as asphalt of the "coated" type.
  • the routing of optical fibers between the generator and the blocks can take place in sheaths along the concrete structures.
  • the generator can be installed, depending on the environment, either recessed to the ground in a manhole, either in a metal base box or polyester on sidewalk, or built into a wall box fencing.
  • This generator can transmit in blocks or elements translucent, via optical fibers, a luminous flux continuously or intermittently to create markup at night visible by vehicles or pedestrians.
  • the device of the present invention allows, depending on the direction penetration of the optical fiber into the block or translucent element, to emit a luminous flux on the visible face of the block which is in the extension of existing complexes (such as pavers or curbs). As a result, the light flux is transmitted to the outside of the structure.
  • each translucent element or block is adapted to the external shape, which facilitates the introduction and fixing the end of the optical fiber to the block or border translucent.
  • optical fiber in the pavement or the border translucent is carried out either from below or in the side depending on the face to light up.
  • the structure modular beaconing device promotes the adaptation of the device to very variable forms of different structures which can be equipped with the beaconing device according to the invention.
  • Such devices can be obtained industrially at lower cost and be implemented quickly and therefore also at lower cost.
  • the present invention makes it possible to use a single lamp for signal an obstacle with different light elements distributed over several meters or tens of meters, along a slide especially.
  • Each of said translucent elements can be fixed on its support (metallic, wooden or concrete) by fixing lugs.
  • the invention improves the optical effect of markup thanks to a relatively large area of emission of light flux towards the exterior of the structure, in comparison with the reduced surface of sections of optical fibers used.

  • Block 6 has grooves 15 and 16 in the lower part extending along respective axes perpendicular to each other, which grooves 15 and 16 open onto the underside or base 42 block 6; in this way, the cables 14, 17 forming part of the prefabricated structure of the pedestrian crossing shown in Figures 1, 3 which comprises said opaque blocks 13 connected by said cables 14, 17, can extend inside the translucent blocks 6 which are set place after the prior establishment of the structure consisting of elements 13, 14 and 17; this also allows, when sealing the translucent block 6 by known means with the rest of the structure, to promote the joining or anchoring of the translucent block 6 by compared to the rest of the structure, thanks to the mechanical connection with cables 14 and 17.
  • the end 4 of the diffuse optical fiber 2 when connected to the generator light, a light beam extending at an opening angle depending on the nature of the fiber and the material used for the realization of the translucent element 6; the end 4 of fiber 2 is secured to block 6, by a cable gland type device 8, screwed in a part of the cylindrical cavity 5 and exerting pressure around the end 4 of the optical fiber to hold it in place; the cavity 5 receiving the end 4 of the fiber is closed at one end longitudinal by a bottom wall 44; according to a variant no shown, the cavity 5 opens at its second end into a second cavity larger than cavity 5 and extending as an extension of it, so that you can insert into the second cavity, the end of a protective sheath for the section of fiber 2, surrounding said fiber section.
  • the elements 6 of translucent borders (such as those illustrated in Figures 7 and 8) are interposed between the elements 13 of concrete curbs and form an integral part of the alignment of border.
  • These light borders 6 are supplied with light by fiber penetrating optics (as illustrated in FIGS. 5 to 8) by a face side 38 of element 6 or else by its base 42.
  • the luminous part 37 is the visible part of the road and provides limit security by its increased visibility due to its brightness.
  • the translucent element 6 in composite material forming a thin-walled cover is fixed to the sections of slides 90 by lugs 92.
  • Element 6 receives the end of an optical fiber 2 which extends along the metal slide 90 ( Figures 13 and 14).
  • optical fiber 2 may walk in a sheath 99 buried at the bottom of the slide such that shown in figure 17.
  • optical fibers will be connected to a generator 3 located behind the slides and placed in a box fixed to the ground or buried.
  • the end of the optical fiber 2 can be fixed by cable gland on the slide 90 and oriented so as to illuminate the front face 98 of the translucent composite element 6.
  • the end piece 4 of the optical fiber 2 can enter the translucent element 6 from the rear of the support 91 slide 90 when passing through a reservation (port 93) in the support 91 (stake or vertical stake) for slide 2 or in the slide.
  • the end piece 4 of the fiber will therefore be directed towards the front face 98 of the translucent element 6.
