Definitions

  • the present invention relates to a beacon of roads and more specifically a light road beacon intended to materialize on permanent carriageways or temporary for vehicles without constitute obstacles likely to produce significant damage in the event of an impact.
  • tags with a light plastic indicator carried by a base fixed or removable.
  • the link between the indicator and the base is ensured by an elastic element allowing a certain mobility of the indicator relative to the base. Warning light can thus escape under a vehicle having deviated from the path traced by this beacon without causing damage to the vehicle.
  • the purpose of the present invention is to provide a beacon whose indicator is resistant, in particular to stresses it experiences when the wheels of a vehicle crush it and whose means of connection of this indicator to plinth are much simpler than the elastic ones set works so far.
  • the invention relates to a tag road including an indicator intended, in service, to be protruding above ground level and a plinth fixing the indicator to a support, in which the indicator consists of an elongated generally cylindrical body comprising an outer plastic casing waterproof and an internal filling of cellular material.
  • the envelope material will preferably be a polychloride flexible vinyl (PVC).
  • PVC polychloride flexible vinyl
  • the tag according to the invention has a base which is formed by a base made of plastic, a first face of which is intended for be fixed and in particular glued to the support while a opposite side to this first side is provided with means to accommodate, in particular by snap-fastening, correspondents of the indicator, these means being brought to a lower end of the sight glass by the inside of the envelope.
  • These fixing means can be of any known nature such as bayonet means, means spruce teeth which cooperate in an elastic manner thanks to to the inherent elasticity of the plastic material work or even a thread.
  • the advantage of having planned the means of fixing the sight glass inside the base of the envelope lies in the fact that these are protected when the indicator is torn off from its base.
  • the envelope has at least one area of least flexural strength and therefore increased flexibility.
  • This area can either be a thinning of the thickness of the envelope provided on an annular area, i.e. an area annular corrugated by one or more grooves or shaped bellows.
  • This area of increased flexibility allows the seeing not to be too easily torn from its base under the effect of a lateral force. To do this, the area of increased flexibility should preferably be placed on the side of the light base.
  • the material of the envelope will be chosen to be chemically and corrosion and it may contain either in its mass or the exterior of the compounds making it fluorescent or reflective. It will also include adjuvants increasing its resistance to light and in particular to ultraviolet.
  • the base is fixed, preferably glued by its first side on a weighing plate sliding in a reserve pot made in the roadway and maneuverable in this pot by means of an actuating cylinder whose body is harnessed to the bottom of the reserve pot and the rod is telescopic with several development segments and with a free end in simple support against a contact surface associated with the sliding plate.
  • the tag of the invention is thus retractable and may be suitable for applications in which it can be necessary to modify the configuration of the traffic on a roadway. Maneuvering the beacon can be manual or controlled, the cylinder being for this last case preferably single acting in order to benefit the effect of gravity for a simple purge of the cylinder in the direction of retraction.
  • the base of the beacon according to the invention is glued to the roadway by his first face.
  • the tag according to the invention shown in drawings includes a light indicator 1 coupled to a base 2.
  • the indicator 1 is constituted by an outer envelope (or skin) 3 in a compact plastic material, of low thickness, waterproof and resistant to corrosion and abrasion.
  • This envelope is in the form of a cylindrical tube closed at one end and open at the base.
  • the tubular shape can be different from a perfect cylinder : it can be a cone or a complex shape such as a ringed cylinder, surmounted by a portion of sphere, at base polygonal ...
  • This envelope is filled with a material alveolar 4, for example a polyurethane foam.
  • this indicator consists of first make the envelope 3 by molding, thermoforming or injection and then use this envelope as a mold in which a polyurethane is frothed. Grip foam material on the inner surface of the envelope is provided by any known known means in particular in a chemical process for the preparation of this internal surface. Placing the foam in the envelope is produced by any known method such as than injection with or without rotational molding ...
  • the base 2 of the tag is made of material plastic, one face 2a of which is intended to be fixed by any means and in particular by bonding to a support 5 (here the upper surface of the road).
  • the side 2b opposite the face 2a is provided with a kind of end piece 6 bearing periphery of the latching means of the indicator light 1 like those shown as an example in Figure 2.
  • the envelope 3 has been filled partially so as to release the open end of this envelope so that it can accommodate the means latching 6 of the base 2.
  • latching means or more generally of fixing, are constituted in Figure 2 by lugs in fir tooth 7 carried by the tip 6 of the base 2 likely to be forced into a corresponding accommodation 8 formed on the inner surface of the casing 3 to the open end of the latter.
  • Other ways can be used such as for example mounting to bayonet or a thread on the base and a thread on the inside of the envelope 3.
  • the plastic nature materials forming the envelope 3 and the base 2 allows, thanks to their elasticity, strength mounting for this snap-in as well as detachment without destruction of these means under the effect of a lateral force applied to indicator 1. It will have been noted that the means worn by the indicator light are located inside the envelope, these are thus protected in particular after being torn off of the light on its base.
  • the envelope 3 can be provided with corrugations 9 (one or more) or with bellows which constitute zones of great flexibility of the indicator. These zones may be located at any height of the indicator, but a preferential zone is that shown in FIG. 2, that is to say close to the base so as to allow the greatest possible clearance without the indicator being torn away from the basement.
  • a cellular material 4 of lower density in the upper part 1 a of the sight glass than in the lower part 1 b so that the head of the sight glass is slight.
  • the transition zone between the two zones will be progressive, for example by adjusting the parameters of the foaming device (nozzle) during the filling of the envelope.
  • this area of great flexibility can be obtained by thinning the thickness of the envelope.
  • the indicator consists of two distinct materials allows it to confer in addition to advantages and qualities mentioned above, the advantage of be able to have a sight glass comprising in its mass, that is to say in the mass of the envelope 3, adjuvants making it fluorescent or reflective. It's not depart from the invention than to provide a particular coating having reflective or fluorescent qualities at the outer surface of the sight glass. Besides, it is easy by the very fact of this constitution in two matters of seeing to make an envelope with a wide variety of texturing of its outer surface allowing it to take various aspects according to the uses to which the tag is intended.
  • Figure 3 illustrates a retractable application of the tag according to the invention in which the indicator 1 is retractable in a reservation pot 10 intended for be located under the roadway.
  • This reservation pot 10 is presented under the shape of a cylinder having a vertical central axis 11 which is common with sight glass 1. Pot 10 has a upper end 12 forming an outer flange. This upper end 12 is partially closed by an attached cover 13 which has an opening central 14 allowing the passage of the light 1. On the opposite, the pot 10 has a lower end 15 which is closed by a bottom 16.
  • the sight glass 1 is integral with its base 2 itself glued to a plate 17 mounted inside reserve pot 10 to slide along axis 3 i.e. vertically between deployment positions and redeployment of the indicator 1.
  • This plate 17 in this case comprises an upper plate 18 on which is glued the base 2 and a skirt 19 mounted with a weak game in the reservation pot 10 so as to be guided parallel to axis 11 when the plate 17 slides in the booking pot 10.
  • the sliding plate 17 is sufficiently heavy to be constantly reminded by its own weight towards the retracted position of the indicator 1. It is here in one piece in metallic material.
  • the sliding plate 17 is actuated between its deployment and deployment positions by a single acting cylinder 20 disposed between the bottom 16 of the pot reservation 10 and the sliding plate 17.
  • This cylinder actuator comprises in this case a body 21 resting on the bottom 16 of the reserve pot 10 and a rod telescopic 22 which has several development segments 23 and whose free end 24 is in simple support against a lower contact surface 25 of the face bottom of the plate 18 of the sliding plate 17.
  • This contact surface 25 is concave in shape so that ensure self-centering of the free end 24 of the rod telescopic 22 of the jack relative to the plate 17, that is to say on axis 11.
  • the indicator 1 can be deployed at the outside of the reserve pot 10 as illustrated by the Figure 3 by controlling the deployment of the telescopic rod 22 of the actuator 20.
  • the rod 22 pushes up the plate sliding 17 which rests on the end 24 of the rod 22 due to its own weight.
  • the LED constitutes a light tag.
  • the indicator disengages from the base and detaches from it without deterioration of the elements of fixation.
  • the upper surface of the base 2 can be arranged flush with the cover 13. It can also take the shape of a dome to avoid any sharp edges projecting from the pavement.
  • base 2 can be of a suitable color to still constitute a brand demarcating lanes on the roadway, which is easy because it is made of plastic.
