Definitions

  • the present invention relates to protective means to be installed on a road or motorway , barrier to protect a motorcyclist in the event of an impact against said barrier.
  • Road (or motorway) barriers are usually formed of supporting posts (normally) fixed to the ground in an upright position, which carry spacers (which in turn carry at least one strip) and at least one longitudinal bar, placed at a greater distance from the ground than that at which the strip is situated, which contributes with the strip to contain the vehicle (car, truck, articulated truck, etc.) during a possible veering off the roadway.
  • a protective element of soft material which covers the post to attenuate the impact of the motorcyclist against said post; - a smooth strip, installed in the bottom part of the barrier to prevent a motorcyclist from impacting against the post and/or from sliding under the bottom strip of the barrier in the event of an accident.
  • Object of the present invention is to create protective means to be installed on a road or motorway barrier to protect the motorcyclist in the event of an impact against said barrier; this object is achieved through protective means having the characterising features set forth in claim 1.
  • FIG. 1 shows diagrammatically a perspective view of a protective element according to the invention
  • FIG. 2 shows diagrammatically a side view of the protective element of Figure 1 ;
  • FIG. 3 shows diagrammatically, in an exploded view, two protective elements and the means adapted to join them to each other and to a supporting post of a barrier;
  • Figure 4 shows diagrammatically a side view of the assembly of Figure 3, assembled.
  • the protective means realised according to the invention, to be installed on a road or motorway barrier to protect a motorcyclist in the event of an impact against said barrier consist of continuous protective elements, placed beneath the strip of the road (or motorway) barrier, which are adapted to continuously absorb the energy due to the impact.
  • continuous absorption is that the energy due to an impact is absorbed by the protective elements along its entire length, rather than at certain points, as is the case in the previously described protective means of the prior art.
  • the protective elements preferably have, in section, two V-shaped parts opposite each other, joined by a substantially flat central part preferably at right angles to the road surface; the end portions of the protective element are preferably bent so as to be substantially parallel to the central part of said element.
  • Two adjacent protective elements are preferably connected to each other, at one of the supporting posts, by an element shaped like the central part of a protective element and pushed into the two adjacent protective elements and by a further plate fixed to the supporting post and to the bent terminal portions of the protective elements.
  • the protective elements can consist of elements of soft, elastic material that are circular, square or rectangular in section.
  • Figure 1 shows diagrammatically a perspective view of a preferred embodiment of a protective element 2 realised according to the invention, which has been designed to keep on the carriageway a motorcyclist who, for accidental reasons, slides on the road surface and to soften his/her impact against said barrier, avoiding harmful consequences for the motorcyclist's body.
  • the protective element 2 has, in section, two V-shaped parts (5, 6) opposite each other and joined by a substantially flat central part 7; the terminal portions 10 of the protective element 2 are preferably bent so as to be substantially parallel to the central part 7 and have holes (omitted in figures 1 and 2 for the sake of simplicity of the graphic representation) to receive means (consisting, in the embodiment shown in figure 4, of fixing bolts 13) adapted to fix thereto at least one plate 9 ( Figure 3) which joins together two adjacent protective elements 2.
  • the central part 7 thereof is preferably at right angles to the road surface.
  • the flat central part 7 of the protective element 2 advantageously has a longitudinal stiffening rib 7', consisting of a portion of the central part 7 recessed and parallel to the plane of said central part, which prevents the collapse of the central part 7 and the possible inward buckling thereof when it is impacted by a motorcyclist.
  • the protective elements 2 realised according to the invention are installed in the bottom part of the barrier 1 and are capable of continuously absorbing energy during the impact of the motorcyclist, since they have been designed to deform in an elastic-plastic manner during the impact and at the same time to maintain their shape, which allows the motorcyclist to be re-directed and prevents him/her from leaving the carriageway.
  • Figure 2 shows diagrammatically a side view of the protective elements 2 of figure 1 ; in Figure 2 the two opposite V-shaped parts (5, 6), the (substantially flat) central part 7 which joins the two V-shaped parts (5, 6) and the bent terminal portions 10 of the protective element 2 can be seen.
  • Figure 3 shows diagrammatically, in an exploded view, two protective elements 2 joined together by an element 8 pushed into the two protective elements 2 and by least one plate 9, fixed to the bent terminal portions 10 of the protective elements 2 and to a supporting post 4 by means of fixing means consisting, in the embodiment shown in figure 4, of bolts 13 inserted into holes formed in the bent terminal elements 10 of the protective elements 2, in the plates 9 and in the supporting post 4.
  • the element 8 has a similar shape to that of the central part 7 of a protective element 2, but slightly enlarged to be pushed into the two adjacent protective elements 2.
  • the assembly system illustrated in Figure 3, comprising the element 8 and at least one plate 9, makes it possible to give continuity to the protective elements 2, to join them to the posts 4 of the barrier 1 and to install easily a barrier 1 comprising the protective elements 2 realised according to the invention even on routes with numerous bends, i.e. on those routes on which their installation is most useful, if not necessary.
  • Figure 4 show diagrammatically a side view of the assembly of Figure 3 assembled: visible in Figure 4 are the two V-shaped parts (5, 6) of the protective elements 2, opposite each other and joined to the substantially flat central part 7, which has the longitudinal stiffening rib 7'; the bent terminal portions 10 of the protective element 2; the element 8, shaped like the central part 7 of a protective element 2, which joins two adjacent protective elements 2 and the plates 9, fixed to the terminal portions 10 of the protective element 2 by means of the bolts 13.
  • the protective elements 2, realised according to the invention, to be installed on the barrier 1 have the following innovative features: - they consist of modular elements preferably made of metal (but, without departing from the scope of the invention, they can be made of rubber or of other plastic or composite materials) having an open section which allows a continuous energy absorption during the impact of the motorcyclist with the protective means, as verified experimentally by the applicant. - the push-in joining of two adjacent protective elements 2 by means of the element 8 considerably facilitates the installation of the protective means;

Abstract

L'invention concerne un moyen de protection constitué d’éléments continus (2) et placé sous la bande inférieure d’une barrière (1), qui absorbe de façon continue l’énergie due à l’impact d’un motocycliste contre ladite barrière. Un élément protecteur (2) présente de préférence, en section droite, deux parties (5, 6) en V opposées l’une à l’autre et jointes par une partie centrale plate (7), (de préférence) à angle droit par rapport à la surface de la route, les parties terminales (10) de l’élément protecteur (2) étant de préférence courbées de façon à être parallèles à ladite partie centrale (7). Deux éléments protecteurs (2) adjacents sont joints l’un à l’autre par un élément (8) présentant la même forme que ladite partie centrale (7) et enfoncé dans les deux éléments protecteurs (2) adjacents et par au moins une plaque (9) fixée à un poteau (4) de support et aux parties terminales (10) des deux éléments protecteurs (2).
