Abstract
Safety end piece mounted in the front end of metal road barriers, wherein the end piece is frontally provided with a sliding support with blades that, when hit by an out of control vehicle, is capable of moving towards a beam of laminated wood and interfering with the blades with the structure of the beam, in such a way that the interference determines a progressive reduction of the forward traveling speed of the sliding support and absorbs the energy of the impact discharged by the out of control vehicle against the sliding support.
Claims10
Safety end piece for road barriers, comprising:
- a beam made of laminated wood, provided with a back end and a front end and supported in horizontal position above a track provided with a back end and a front end by means of a fixed supporting means associated with said back end of the track and a plurality of sliding support means along said track, which are capable of tightening points of the beam comprised between said back end and front end of the beam;
- and
- a slider suitable for being inserted in said front end of the track, with the possibility of sliding freely, and provided with a box body with a mouth suitable for exactly receiving said front end of the beam;
- wherein said box body is internally provided with a plurality of blades disposed behind said mouth, said blades being suitable for longitudinally cutting the beam, progressively reducing its length, when said slider is submitted to a force capable of moving it forward towards said back end of the track;
- wherein, during the forward movement, said slider progressively interferes with said sliding support means of the beam, forcing said sliding support means to move towards the back end of the track.
