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 stakes (normally) fixes 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.
  • the patent no. FR 2 796 090 discloses means suitable for protecting a motorcyclist in the event of an impact against a road or motorway barrier, comprising two superimposed series of aligned tubular elements, which are connected to each other and to a stake of the barrier through fixing means (placed between two adjacent tubular elements of each series and fixed to the stake of the barrier), which carry pins, each of which is inserted into one of the tubular elements.
  • German utility model no. DE 1 949 782 discloses means suitable for protecting a motorcyclist in the event of a impact against a road or motorway barrier consisting of two V-shaped strips made of metal sheet, which are connected to each other to form a closed structure fixed to the stakes of the barrier.
  • FR 2 313 503 A1 discloses a safety barrier for road and motorway comprising a plurality of posts and cross pieces fixed to the posts by means of screws which require the posts to be perforated.
  • the cross pieces are suitably spaced along the posts and connected each other by fixing means comprising a plate and screws. Such fixing means between adjacent cross pieces are dangerous in case of impact of a motorcyclist against the barrier.
  • US 1 643 555 A discloses a guard comprising posts arranged at intervals along the side of a roadway and rails secured to the front faces of the posts by means of screws.
  • the rails vertically extend along the posts and are positioned at such height over the surface of the roadway to be engaged by the hubs of a skidding motor vehicle and to stop the movement of the same.
  • the rails consist of sections, whose meeting ends are connected by means of a bridging member and a screw with a lock nut.
  • WO 03/104568 A1 discloses a guide rail comprising a plurality of rail segments connected end to end by fastening means.
  • the segments comprise on one end an end section with a reduced cross section such that the adjoining rail segments can be connected by telescoping and fastening.
  • the above listed documents provide the perforation of the posts for fixing thereon, for example by means of screws, the cross pieces, as well as the mechanical connection of adjacent cross-pieces. They present some drawbacks.
  • the posts have to be perforated in loco during the connection of the cross pieces, with consequent localized loss of the anticorrosive protection, typically zinc plating, and serious decrease of the working life of the system.
  • these latter are at least potentially dangerous for the motorcyclist since they protrude from the surface of the barrier facing towards the road.
  • Object of the present invention is to obtain protective means to be installed on a road or motorway barrier to effectively protect a motorcyclist in the event of an impact against said barrier; this object is achieved through continuous protective means placed beneath the lower strip of the barrier and fixed to the barrier supporting stakes, having the characterizing features set forth in claim 1.
  • a protective element consists of a box-type elongated body with an open rectangular section, where the side of the box-type body facing the supporting stakes of the barrier has a longitudinal opening (i.e. an opening parallel to the longitudinal axis of the protective element) on the whole length thereof; the box-shaped body is preferably tapered (i.e. its height gradually decreases passing from one end to the other end thereof) to allow two adjacent protective elements to be friction jointed or interference fitted each other by inserting the end of a protective element having a smaller height into the end of an adjacent protective element having a greater height.
  • a protective element is fixed to a supporting stake by means of a plate inserted into the protective element and of a counter-plate placed outside the protective element and tightened against the plate by at least one bolt passing through the opening formed in the open side of the protective element: the plate and the counter-plate, tightened each other by the at least one bolt, block the edges of the open side of the protective element against a tab belonging to the supporting stake,
  • Figure 1 schematically shows a front view of a first embodiment of a protective element 1 according to the invention, which consists of a tapered (i.e. its height gradually decreases passing from the value D at one end to the value D1, smaller than D, at the other end thereof) elongated box-type body.
  • a tapered i.e. its height gradually decreases passing from the value D at one end to the value D1, smaller than D, at the other end thereof
  • the difference between the heights D and D1 is not lower than the thickness of the wall of the box-type body forming the protective element 1.
  • this tapering allows two adjacent protective elements 1 to be jointed by inverting the end having height D1 of a protective element 1 into the end having height D of the adjacent protective element 1.
  • Figure 2 schematically shows - sectioned along the section plane A-A of Figure 1 - the protective element 1, which is rectangular in section and has the longitudinal opening 14 at its side 2 facing the supporting stake 5, when the protective element 1 is installed ( Figure 3 ).
  • the reference numeral 2 identifies the greater sides of the protective element 1, which are perpendicular to the road plane 4, when the protective element 1 is installed ( Figure 3 ); the reference numeral 3 identifies the smaller sides of the protective element 1, which are parallel to the road plane 4, when the protective element 1 is installed ( Figure 3 ); the reference numeral 14 identifies the longitudinal opening formed in the open side 2.
  • Figure 3 schematically shows a sectioned, side view of a protective element 1 fixed to a supporting stake 5 by means of a plate 6 inserted into the protective element 1 and of a counter-plate 7 placed outside the protective element 1 and tightened against the plate 6 by bolts 8, passing through the opening 14 formed in the open side 2 of the protective element 1: the plate 6 and the counter-plate 7, tightened each other by the bolts 8, block the edges of the open side 2 of the protective element 1 against the tab 9 belonging to the supporting stake 5, as can be seen better in Figure 4 .
  • the means for fixing a protective element 1 to a stake 5 further comprise a prismatic body 10 (visible better in Figure 4 ) placed between the edges of the open side 2 and the area of the counter-plate 7, that contacts the edges of the side 2 when the counter-plate 7 is installed.
  • the thickness of the prismatic body 10 is preferably equal to that of the tab 9.
  • the plate 6 and the counter-plate 7 are tightened each other by two bolts 8, but, without departing from the scope of the invention, the plate 6 and the counter-plate 7 can be tightened each other by a bolt 8 or three or more bolts 8.
  • the distance between two adjacent supporting stakes 5 must be not lower than the length of the protective element 1, but, since the plate 6 can slide inside the protective element 1, such distance can be chosen each time to better fulfil specific requirements.
  • Figure 4 schematically shows the assembly protective element 1 - stake 5 of Figure 3 , sectioned along the section plane B-B of Figure 3 ; in Figure 4 a section of the protective element 1, the supporting stake 5 with the tab 9, the plate 6 and the counter-plate 7, tightened against the plate 6 by the bolt 8 to block the edges of the open side 2 of the protective element 1 against the tab 9, and the further prismatic body, are visible.
  • the supporting stake 5 consists of a section of a 1-shaped section bar, but without departing from the scope of the invention, the supporting stake 5 can be otherwise shaped each time to fulfil specific requirements, provided that a tab 9 is present.
  • Figure 5 schematically shows the junction area between two adjacent protective elements 1, connected by inserting the end having height D1 of a protective element 1 (shown in broken line in Figure 5 ) into the end having height D of the adjacent protective element 1.
  • FIGs 6 to 10 schematically show a second embodiment (1') of a protective element according to the invention, which differs from the protective element 1 described with reference to Figures 1 to 5 at least for the fact that the at least one portion of the smaller sides 3 of the protective element 1' is "concertina" folded, i.e. it has saw tooth longitudinal folds 12 on the whole length of the protective element 1', which resiliently absorb at least part of the energy due to the motorcyclist's impact.
  • the side 2' of the protective element 1' opposite to the open side 2 and facing the roadway preferably has a longitudinal stiffening rib 13.
  • each of the smaller sides 3 of the protective element 1' has three longitudinal folds 12, but without departing from the scope of the invention, each smaller side 3 of the protective element 1' can have less than three or more than three longitudinal folds 12.
  • the protective elements obtained according to the invention have the following innovative features:
