Definitions

  • the subject of the present invention is a method for retaining vehicles on a road and safety devices installed along roads or motorways either on the lateral part or between the two carriageways of a motorway or on the carriageway itself for signaling and protect a site.
  • a first category is that of slides or deformable safety rails in the event of impact, which generally consist of metal profiles.
  • a second category is that of safety barriers made up of reinforced concrete or prestressed concrete walls which do not undergo any deformation or displacement during the impact of a vehicle.
  • a third category is that of traditional curbs which are used as wheel guards.
  • Safety barriers try to brake a sinking vehicle by absorbing its kinetic energy by deformation of the slide, but this effect is ineffective as soon as the mass and / or speed of the vehicle are high. Safety barriers are dangerous for motorcyclists hitting them.
  • Safety barriers are very effective in preventing a vehicle from accidentally leaving the road. On the other hand, they are very aggressive for the vehicle since the kinetic energy of the vehicle is absorbed by the crushing of the body. Concrete safety barriers are expensive and installation work is long. In addition, it can happen that a vehicle that hits a safety barrier turns over because the front wheels climb over the wall due to the high coefficient of friction of tires on concrete. Concrete curbs are often climbed by vehicles in distress for the same reason.
  • US patent A 2 279 942 (Hausherr) describes safety devices for motorways, the material of which is not specified. These devices have a concave side towards the road and a vertical wall at the rear. This flank and this wall delimit a space in which is housed a longitudinal reservoir which contains an oil. Wicks passing through holes in the concave flank soak in the oil and continuously pour drops of oil onto the concave flank.
  • Patent CH A 429 806 (Bucher) describes road safety devices which comprise a slide or a rail made of concrete, steel or a light metal which is connected to the supports by a damping device constituted for example by a spring or by concentric tubes easily deformable or by stirrups filled with a cellular body.
  • the rails can be combined with wheel guard edges with a concave surface.
  • the objective of the present invention is to provide means which facilitate the sliding of damaged vehicles against slides or rails or safety barriers or curbs placed along roads and motorways which means are easier and less expensive to implement as lubricating liquids and are permanent.
  • the means according to the invention include laying along a road, safety devices such as barriers, curbs, rails, wooden log rails or low walls forming a continuous surface substantially parallel to the axis off the road to prevent vehicles from accidentally getting off the road.
  • safety devices such as barriers, curbs, rails, wooden log rails or low walls forming a continuous surface substantially parallel to the axis off the road to prevent vehicles from accidentally getting off the road.
  • the object of the invention is achieved by a process according to which a strip of the continuous surface exposed to the shocks of vehicles is covered with a solid or pasty sliding coating having a coefficient of static friction with the rubber of less than 0.4 of such that a vehicle accidentally hitting said continuous surface slides along said strip.
  • a device comprises a strip of continuous sliding coating parallel to the road, which sliding coating is composed of a solid or pasty material having a coefficient of static friction with the rubber of less than 0.4.
  • the sliding coating is composed of polytetrafluoroethylene or of a solid silicone resin.
  • the sliding coating consists of a layer of graphite particles applied by friction against said surface exposed to impact.
  • the sliding coating is a layer of wax or paraffin composed of a solid alkane having a number of carbon atoms greater than 15.
  • the sliding coating is a paint or a grease containing particles of graphite or molybdenum sulfide.
  • the sliding coating comprises microbeads having a diameter of less than 3 mm which are fixed by a solid binder, for example by an adhesive film.
  • the invention results in new road safety devices.
  • the devices according to the invention have the following advantages: - They're permanent. - In the event of an accidental impact of a road vehicle against the safety device, the vehicle slides easily along the slippery surface, gradually losing its kinetic energy. This results in better security for the passengers of the vehicle due to the absence of crushing and / or overturning of the vehicle as well as a reduction in material damage to the vehicle.
  • the vehicle sliding along the sliding surface is guided by it and it can be replaced parallel to the road which prevents it from passing in the opposite lane of a highway or that it is returned towards the lane in which it was traveling, hence a reduced risk of violent impact with other vehicles.
  • a motorcyclist who accidentally hits a safety device according to the invention slides against the slippery surface and the severity of the injuries is less.
  • the solid or pasty sliding coatings according to the invention have the advantage of being easier to to implement, to be much less expensive to operate and to be also more aesthetic and more discreet. It is the same with respect to the known device comprising an endless belt mounted on rollers or on balls.
  • Figures 1 and 2 show an element 1 of a safety edge which is constituted by identical elements which are simply placed end to end along a road to prevent road vehicles from leaving the road.
  • This element is a profile, for example a metal profile obtained by rolling, by centering or by bending a metal sheet.
  • flank 1i which is directed towards the road and an external flank 1e which is on the side opposite the road.
  • the internal flank 1i is extended downwards by a sole 3 slightly down towards the road.
  • the internal edge 5 of the sole 3 is folded at a right angle and bears on the ground.
  • the sole 3 is connected to the internal flank 1i by a curved surface 2 whose concavity is directed towards the road.
  • the width in the transverse direction of the sole 3 varies according to the applications.
  • the sole 3 has a transverse width of the order of 20 cm so that the wheels of a running vehicle which leaves the road by making an angle of 20 ° to 30 with the axis thereof. ° are supported on the sole 3 before striking the internal flank 1i which has the advantage of limiting the lateral displacement of the edge which is held in place by the weight of the vehicle.
  • the transverse width of the sole 3 is less than approximately 10 cm so that, in the event of a vehicle impact against the edge, the vehicle tire meets the internal sidewall 1i before pressing on the sole 3.
  • Figures 1 and 2 show a preferred embodiment in which the outer flank 1e has the shape of a circular sector centered on the inner edge 5 of the sole 3. This shape allows good alignment of the outer flank despite the irregularities in the floor on which the border is laid. It is sufficient at the time of installation to align the internal ends 5 of the various elements.
  • the lower edge of the external flank may have a surface 4a which is curved upwards to facilitate the sliding of the profile on the ground or else a surface perpendicular to the ground.
  • the internal flank 1i has at its upper part a curved surface 7 whose convexity is directed upwards and towards the road, which is tangentially connected to the cylindrical surface 4 of the rear flank and to the curved surface 2 of the front flank.
  • the convex curved surface 7 carries a sliding coating 8 which is located at a distance from the ground such that the tire of a vehicle which leaves the road strikes this coating 8.
  • the coating 8 is a sheet or a layer of polytetrafluoroethylene or of solid silicone resin or graphite or any other solid material having a coefficient of static friction with the rubber of less than 0.4.
  • the edges 1 slide on the ground by absorbing part of the kinetic energy of the vehicles.
  • the front wheels which are the steered wheels, straighten by sliding against the surface and, in most cases, the impact brings the vehicle back in the direction of the axis of the roadway.
  • metal crash barriers have a coefficient of static friction with rubber greater than 0.6.
  • edge elements 1 shown in Figures 1 and 2 advantageously include, at their two ends, a notch 6 which allows the passage of the bolts and tools required when fixing the elements together.
  • FIG. 3 shows a cross section of an alternative embodiment of a border according to the invention which is composed of a curved metal profile which has a substantially horizontal sole 3 which is placed on the ground, a curved surface 2 which connects the sole with an inclined and substantially planar internal flank 1i which is tangentially connected to a cylindrical surface 7 whose convexity is directed towards the road and which carries on its convex external face a sliding coating 8.
  • FIG. 4 represents a cross section of a road safety barrier composed of a low wall 9 forming a continuous line bordering a road.
  • the wall 9 can be a concrete wall poured on site or composed of prefabricated elements placed end to end.
  • the reference 9i designates the internal flank, that is to say the one facing the road.
  • a metal profile 10 is fixed for example by bolts or by expansion plugs or for any other equivalent fixing means.
  • the profile 10 has a convex surface facing the road and this convex surface has a sliding coating 11.
  • the profile 10 and the sliding covering 11 are symmetrical with respect to a horizontal plane PP ′ and the height of this plane above the ground can vary between 30 cm and 60 cm depending on whether one wishes to straighten the wheels of a vehicle after an impact against the barrier or only allow a good sliding of the vehicle body against the slippery surface.
  • FIG. 5 shows a cross section of another embodiment of a metal profile 12 according to the invention intended to be placed between two traffic lanes to separate them.
  • the profile 12 is preferably symmetrical relative to a longitudinal vertical plane V V ′.
  • the lower ends of the lateral flanks are extended by surfaces 16a and 16b slightly inclined downwards towards the outside, which are curved inwards to form a sole 17 placed on the ground.

  • the internal face of this rib which is directed towards the roadway has a convex surface.

  • Such concrete wheel surrounds are known. In practice when a vehicle accidentally leaves the road, the wheel often climbs the curb and the vehicle crosses it as soon as the angle of incidence of the vehicle and / or the speed of the vehicle are high. This is due to the high coefficient of friction of the tire against the concrete which leads to good adhesion of the tire to the convex surface of the rib 22 when it strikes the latter.
  • edges 18 are equipped with a sliding coating 24 which is disposed against the convex internal face of the rib 22.
