Definitions

  • the present invention relates to a protection device for guardrail.
  • guardrails are arranged on the external part of the carriageway, e.g. also in a central position, as a traffic divider on dual carriageways, in order to improve the safety of drivers by reducing the effects of accidents or skidding.
  • guardrails are designed to withstand a collision in such a way as to keep the vehicle involved inside the protected carriageway, preventing the invading of the opposite lane or running off the road.
  • the guardrails known to date generally consist of a longitudinal barrier which has an outer surface facing the carriageway and holding means associated with the longitudinal barrier on the opposite side with respect to its outer surface.
  • These holding means are mainly made up of a substantially vertical supporting element anchored to the ground and of a substantially horizontal connection element placed between the supporting element and the longitudinal barrier.
  • Guardrails often constitute a source of danger for road users and in particular for motorcyclists, cyclists and pedestrians.
  • Both the barrier and the holding means do in fact have a high number of outward-facing protrusions and edges which can be dangerously intercepted by a motorcyclist, a cyclist or a pedestrian both when travelling along the carriageway onto which the guardrail faces and when travelling along bicycle or pedestrian paths behind the guardrail itself.
  • these pedestrian and/or cycle paths are separated from the carriageway on which the motor vehicles or motorcycles pass by the same guardrails. More precisely, the longitudinal barrier of the guardrails faces the carriageway used for the transit of motor vehicles and motorcycles, while the holding means of this barrier face towards the pedestrian and/or cycle paths, with consequent obvious danger for the users of such paths.
  • protection elements are shaped in such a way as to completely cover the entire guardrail, i.e. both the external barrier and the relative holding means.
  • this type of protection element shaped in such a way as to fully cover a guardrail, involves the need, in order to carry out fitting, to make structural changes to the guardrail itself.
  • the guardrail must then undergo new type-approval, in order to determine whether its mechanical properties and its ability to absorb shocks have not been altered by the structural changes made.
  • protective devices for guardrails including elements for covering the connection means.
  • the main aim of the present invention is to provide a protection device for guardrails which is applicable to the existing guardrails and capable of protecting anyone.
  • one object of the present invention is to provide safe protection for the parts of the guardrail without this requiring any structural change or alteration of the guardrail itself.
  • Another object of the present invention is to provide a protection device for guardrails which is easy to fit and at the same time requires significantly lower production and fitting costs than known types of protective devices.
  • Another object of the present invention is to devise a protection device for guardrail that allows overcoming the aforementioned drawbacks of the prior art in a simple, rational, easy, effective to use and low cost solution.
  • the present protection device for guardrail comprising at least one longitudinal barrier having an outer surface facing a carriageway and at least one supporting element which can be anchored to the ground and connectable to the barrier on the opposite side of the outer surface, characterized by the fact that it comprises contoured protection means which are adapted to cover at least partly at least the upper portion of the supporting element.

  • the device 1 is therefore associable with a guardrail, indicated in the Figures by reference numeral 20, comprising at least one longitudinal barrier 21 having an outer surface 21 a facing a carriageway.
  • the outer surface 21 a is delimited at the top and at the bottom by flaps 31.
