Definitions

  • a safety barrier for guard rails of the type that is installed by securing to a post, the upper part of which comprises a barrier that is perpendicular with respect to said post and projects out with respect to the road way or verge, characterised in that it comprises at least one flexible barrier, underneath and parallel to the barrier, projecting out with respect to the roadway, with two lateral fins with longitudinal tabs and located at their ends, bent towards the post, together with at least one bow fixed at its centre to said post underneath the barrier, the ends of which are inserted inside the lateral fins with tab in a sliding fashion, adopting a convex configuration with respect to the mentioned post.
  • guard rail protectors are known in the technical field. Some affect post protection, others on protection of the metal barrier and third group introduce one or more lower barriers to prevent motorcyclists sliding underneath.
  • Spanish patent No 200500537 ( ES2288061 ) is known, in the name of Mr Carlos RAY ⁇ N MART ⁇ N, from the year 2005, which refers to an elastic system for protecting motorcyclists in road containment systems. It is a device that is installed at the sides of roads and designed to improve motorcyclist safety in relation to safety barriers or railings in use. It consist of a continuous band of elastic material, eventually reinforced with longitudinal fibres or elements made of rubber, in general from used tyres, which are secured to the safety barrier posts and can acquire an initial installation tension which permits recovery after impacts. An elastic grille is fixed to this continuous longitudinal band in order to guarantee that no part of the motorcyclist can pass the system position during a collision. This is a more economic alternative to metal solutions because it makes use of recycled material.
  • Utility Model No 200701994 ( ES1066189U ) is also known, in the name of AMATEX, S.A., from the year 2007, which refers to a continuous system that can be installed on road barriers for motorcyclist safety, characterised in that it comprises lower screens securely fixed to the road barrier and/or its fixing posts by means of shock absorbers; with each lower screen structured into groups of boards and straps backed together in pairs and mounted on said shock absorbers, thus forming an angle of convergence with each shock absorber structured on an arm and a connecting part, the geometry and layout of which condition the cited angle of convergence of the lower screens.
  • European Patent No 1184515 also belongs to the technical field, in the name of SEC ENVEL, S.R.L., from the year 2001, which refers to a safety barrier to be installed along the length of vehicle roads, which includes at least one horizontal rails, secured to vertical supports and also includes a lower screen described as "for protection" which presents two edges, respectively upper and lower, and designed to prevent a two-wheeled vehicle involved in an accident, sliding along the road and/or its driver who has fallen to the ground from passing underneath the rail, characterised in that the lower protection screen is suspended by means of arms that extend above the upper edge of the lower screen and fixed to the single rail or that rail which is closest to the ground, with the lower screen freely extending without any other means of securing other than the arms, in a substantially vertical average plane that is clearly located under the vertical supports with respect to an observer located on the road, with these arms being made of a material and having dimensions so that they form functional barrier elements, calibrated to flex non-elastically and allow the lower screen to pivot with resistance due
  • the present invention is an improvement in the sector of inventions to protect motorcyclists against the dreaded guard rails.
  • the guard rail configuration comprises a post, usually H-shaped, which includes cutting edges and a rigid upper metal barrier arranged transversally with respect to said post which occasionally also includes cutting elements.
  • the inventions belonging to the technical field are either economically unfeasible or do not produce the desired effect of reducing the impact.
  • the present invention is a great advance in the sector because, on the one hand, it prevents the motorcyclist from losing a member and, on the other, avoids the person from sliding uncontrollably underneath the metal barrier, it is simple and easy to install and lastly, reduces the impact so that the motorcyclist is not injured by the striking against the guard rail.
  • It essentially comprises an elastic barrier that is positioned below the metal barrier and secured to a post by a flexible bow, which is firmly fixed to the post and the arms of which open more or less, depending on the pressure exerted on said elastic barrier when the motorcyclist strikes the elastic band.
  • the use of a bow allows at least two points to exist to absorb the impact of the striking the flexible barrier, with these two points not being fixed as in the examples in the background, but can move instead. This provides the advantage that even when the motorcyclist impact happens near the previously cited point, the bow operates correctly with all its absorption capability.
  • the bow adopts a convex configuration with respect to the post.
  • This convex configuration provides longitudinal tension to each of the sections that make up the elastic barrier, thus permitting shock absorption and recovery after the impact.
  • the inventor has included non-return safety mechanisms so that, in the assumption of an unexpected return of the elastic barrier towards its original position this is blocked by the guide stubs or tubes.
  • One objective of this invention is a safety barrier for guard rails, of the type that is installed by be being fixed to a post which, at the top comprises a barrier perpendicular with respect to said post and project out with respect to the roadway or verge, characterised in that it comprises at least one flexible barrier, under and parallel to the barrier and projecting with respect to the roadway, with two lateral fins with longitudinal tabs and located at its ends, bend towards the post and at least one bow, fixed at its centre to the referred post, under the barrier, the ends of which are inserted into the side fins with tabs in a sliding fashion, adopting a convex configuration with respect to the mentioned post.
  • Figure 1 illustrates a post 1, a barrier 2, flexible barriers 3 and a roadway 7 with its verge 9.
  • Figure 2 shows the post 1, the flexible barrier 3, a bow 5, connection means 11 and securing means 10 for the bow to the post.
  • Figure 3 includes the post 1, the flexible barrier 3, lateral fins with tabs 4, the bow 5, ends 6 of the bow, guide stubs 8, connection means 11 and securing means 10.
  • Figure 4 shows the tabs 4 the guide stubs 8 or tubes, an internal spring 22 and a drill hole 20.
  • Figure 5 illustrates the tabs 4, the guide stubs 8 or tubes, the internal spring 22 and a toothed billet 21 with its teeth 23.
  • the flexible barrier 3 which, in this embodiment is more advanced than the barrier 2 (metal), because the distance between the post 1 and the flexible barrier 3 is greater than the distance between the post 1 and the barrier 2.
  • barrier 3 Since barrier 3 is flexible, it absorbs the impact that could be received by the motorcyclist and, at the same time, its longitudinal configuration covers the post 1, so that it prevents problems of losing members that was described in the DISCLOSURE OF THE INVENTION and lastly, the motorcyclist is prevented from sliding uncontrollably under the barrier 2 of the guard rail.
  • the sequence is as follows: when the motorcyclist's body makes contact with the flexible barrier 3 it moves to inwards.
  • the guide stubs 8 located at the ends of the bow 6 and positioned inside the lateral fins with tabs 4, enable the bow and flexible barrier to function like a slider and both move in opposite directions, with the guide stubs 8 moving in direction of the ends of the flexible barrier 3, and thus absorbing the impact.
  • Various flexible barrier 3 sections can be joined by securing means 11, which could be connection pipes and rubber seals for enhanced protection and finish. This option could be highly beneficial because when the motorcyclist impact is produced against the flexible barrier 3 and the bow deforms absorbing part of the impact energy, the connection of the various flexible barriers 3 allows “collaboration” between them in absorbing said energy.
  • the inventor has thought of the possibility that the first and last ends of the flexible barrier 3 where a module (a continuous series of flexible barriers) terminates, are curved, to avoid sharp elements.
  • the mentioned guide stubs 8 or tubes comprise an internal spring 22 that partially covers the guide stubs 8 or tubes when these are inside the tabs 4.
  • the first of the proposed solutions would consist of the tabs 4 comprising at least one drill hole 20, with sufficient diameter for the guide stubs 8 or tubes to fit inside when they pass over said drill hole 20.
  • the present invention describes a new safety barrier for guard rails.
  • the examples described here do not limit the present invention, for which reason it may have various applications and/or adaptations, all within the scope of the following claims.
