Definitions

  • the present invention relates to a variable configuration or geometry road barrier, including energy dissipating means.
  • guard-rails which usually comprise metal section members, affixed to upright associated with the ground near the road edges.
  • the aim of the present invention is to overcome the above mentioned problem, by providing a variable configuration road barrier, which is adapted to provide a high dissipation of the impact energy, so as to prevent the vehicle from being subjected to high elastic reaction forces.
  • a main object of the present invention is to provide such a road barrier which can be assembled in a very simple and quick manner, which comprises a very reduced number of component parts, and which, moreover, is very reliable and safe in operation.
  • a variable configuration road barrier including energy dissipating means
  • said barrier comprises a base plate, which can be affixed to the ground, said base plate supporting an upright pivoted to said base plate and provided, on the side thereof facing the ground surface, with means for coupling a barrier element, there being moreover provided a strut, arranged on the upright side opposite to said barrier and pivoted, at the top end portion thereof, to said upright and, at the bottom end portion thereof, to said base plate, said upright being moreover provided, between the region thereof pivoted to said strut and the region thereof pivoted to said base plate, with means for varying the useful length of said upright, for allowing said upright to partially rotate with respect to said base plate, toward the strut; near said upright length varying means there being furthermore provided energy dissipating means which operate against the length variation of said upright.
  • variable configuration or geometry road barrier including energy dissipating means, which are illustrated, by way of an indicative, but not limitative, example, in the figures of the accompanying drawings, where:
  • the first embodiment of the road barrier according to the present invention which has been shown in Figures 1 to 3 and has been generally indicated at the reference number 1, comprises an upright 2, vertically extending and being pivoted, near the bottom end portion thereof, to a base plate 3 which is affixed to the ground.
  • the upright 2 is provided, on the side thereof provided for facing the road surface, with means for connecting at least a barrier element 4.
  • the road barrier assembly further comprises a strut 5, which is arranged on the side of the upright 2 opposite to the road surface and being pivoted, at the top end portion thereof, to a middle region of the upright 2.
  • said strut 5 is pivoted, at the bottom end portion thereof, to a base plate 3a which can be made as a single piece with the base plate 3 or, as is shown, it can consist of a separated element affixed, as the base plate 3, to the ground near the edges of the road.
  • the road barrier assembly owing to the pivoting of the upright 2 to the strut 1 and the pivoting of the latter to the base plates 3 and 3a, will have the configuration of a three-hinge arch.
  • the barrier assembly comprises means for varying, upon an impact, the useful length of the upright 2 and, more specifically, these upright length changing means comprise a pivot pin 6 which pivotably connects the upright 2 to the base plate 3.
  • the pin 6 passes through a slot 7 which is provided through the base plate 3 and extends along a direction with a vertical component.
  • energy dissipating means operating against this variation of the useful length of the upright.
  • said energy dissipating means substantially comprise elements adapted to provide a narrowing, to a size less than the diameter of the pivot pin 6, of the slot 7 at the region not occupied by the pin 6, as the upright 2 is in a rest condition, that is as it vertically extends without impacts exerted thereon.
  • the narrowing means comprise a dissipating plate 8 which is affixed, for example by welding, to the base plate 3, at the slot 7.
  • the end portion of the dissipating plate 8 facing the pin 6, as the upright 2 is under not stressed conditions, is provided with a cut-out or beveled portion 9, adapted to prevent the pin from locking as a motor vehicle impacts gainst the barrier.
  • the dissipating plate 8 can also be advantageously provided with a first portion 10 and a second portion 11 having mutually different thicknesses.
  • the first portion 10 has a thickness less than the thickness of the second portion 11, so as to provide an increasing energy dissipating effect, as the impact force increases.
  • the subject road barrier in its second embodiment, shown in Figures 4 to 6, and generally indicated at the reference number 21, comprises an upright 22 which vertically extends and is pivoted, near its bottom, to a base plate 23, affixed to the ground.
  • the upright 22, likewise the upright 2 of the first embodiment, is provided, on the side thereof provided for facing the road surface, with means for coupling at least a barrier 24, and is pivoted, on the side thereof provided for facing the opposite portion, with respect to the road surface, to a strut 25.
  • the strut 25 is pivoted, at the top end portion thereof, to a middle region of the upright 22 and is pivoted, at the bottom end portion thereof, to a base plate 23a which can be made as a single piece, or as a piece separated from the base plate 23.
  • the means for varying the useful length of the upright 22 comprise two assembled pieces of the same upright 22.
  • the upright 22 comprises a bottom portion 22a, pivoted to the base plate 23, and a top portion 22b, slidably associated, along a direction parallel to its longitudinal extension, with the bottom portion 22a.
  • the top portion 22b is connected to the bottom portion 22a by a pin 26, which is in turn coupled to the top portion 22b and passes through a slot 27, formed through the bottom portion 22a and extending along a direction with a vertical component.
  • the energy dissipating means comprise, in a like manner to that disclosed for the first embodiment, means for narrowing or throttling the slot 27, which, any stresses on the upright 22 being absent, will limit the size of the slot 27 portion not engaged by the pin 26, to a size less than the diameter of said pin 26.
  • the above mentioned limiting or narrowing means also in this second embodiment, comprise a dissipating plate 28, which is coupled to the bottom portion 22b of the upright 22, for example by welding, and being preferably constituted by two portions, indicated respectively at 30 and 31, having different thicknesses.
  • the end of the dissipating plate 28 facing the pin 26 is provided with a lead-in beveled portion.
  • variable configuration or geometry barrier including energy dissipating means, according to the present invention.
  • the upright 2, respectively 22 Upon an impact, the upright 2, respectively 22, will be caused to partially turn toward the outside of the road surface, and such an oscillation will be allowed exclusively by a variation of the useful length of the upright 2 respectively 22.
  • said variation of the useful length of the upright 2 or 22, can be performed, in the barrier, according to the present invention, only by causing the pin 6 or 26 to slide in the slot 7 or 27.
  • the construction of the dissipating plate 8, which comprises several sequential portions of mutually different thicknesses, will allow the barrier to provide a different performance, depending on the impact forces applied to the upright 2 or 22.
  • variable configuration or geometry safety barrier will fit its configuration or geometrical pattern depending on the impact energy, and will respond gradually by vertical and horizontal displacements which are controlled by the energy dissipating means associated to the barrier, which, after a dissipating operation, will operate as a safety limit means.
  • the subject barrier will provide a preset pattern of the forces acting on the bottom fixing or anchoring means of the barrier itself.
  • variable configuration or geometry road barrier including energy dissipating means, according to the present invention, fully achieves the intended aim and objects.
  • variable configuration road barrier which is specifically designed for preventing motor vehicles from being resiliently rejected from the barrier upon accidental impacts.
  • the used material as well as the contingent size and shapes, can be any, depending on requirements.
  • the subject barrier is adapted to absorb the greatest portion of the impact kinetic energy, as an impact occurs against said barrier, and this by providing such a resilient resistance effective to slow down the motion of the vehicle in a gradual manner.
  • the above disclosed sliding means upon achieving their limit position, will allow the subject barrier to provide a holding action on the motor vehicle preventing the latter from being ejected from the road.
