Definitions

  • the present invention relates to a movable element guard-rail.
  • guard-rails consist of rigid elements, of a comparatively strong material, arranged along the roadway and adapted for absorbing the kinetic energy from a vehicle impacting thereagainst.
  • the main object of the present invention is to provide a guard-rail which is so shaped as to stop the vehicle impacting it in a less dangerous manner and without dangerous bouncings on the road.
  • the guard-rail according to the invention is essentially characterized in that it consists of a series of elements which are pivoted on a fixed pin at their middle lines, each element being movable with respect to the others said elements being coupled to unelastically absorb the kinetic energy generated by an autovehicle impact.
  • each element cooperates with the adjoining element through the interposition of loose coupling means, thereby the autovehicle impact causes a plurality of adjoining elements to rotate about their pivoting pins.
  • the coupling means consist of a fork member arranged at at least one end of an element, in which fork member there is loosely engag­ed the end portion of the adjoining element, said end portion of said adjoining element being of substantially pointed shape.
  • the resistance against rotation of the single elements about their pivot pins is suitably adjusted by means adapted for providing a given friction between the fixed pin and movable element.
  • the guard-rail consists of a series of reinforced concrete elements 1, or optionally light boxes, metal prefabricated elements or vibrated concrete elements, which are filled in situ with concrete or inert material mixtures, each having a fork-shaped end 2 and a pointed end 3.
  • Each element 1 is provided, on the middle or center line thereof, with a hole 4 in which is freely seated a vertical pin 5 carried by a concrete pole 6, embedded into the roads surface P so as to allow for the element 1 to rotate (arrows F) as it is impacted.
  • guard-rail is generally formed by an alternating series of elements 7 and 8, each of which is also pivoted on a pivot pin 5.
  • the elements 7 differ since they have two pointed ends, while the elements 8 differ because they have both their ends in the form of a fork.
  • the guard-rail assembly will absorb unelastically the impact energy, that is the impact energy from the right side and the left side, and thus this solution is specifical­ly adapted for arranging the guard-rail at the center line of a road having opposite lanes.
