Definitions

  • the present invention relates to a modular protection element for motorcyclists or cyclists that provides great safety to motorists or cyclists who are fired towards the shoulder, avoiding its impact against the supports of the guardrails or "quitamiedos" and absorbing energy from the impact.
  • protection elements are that described in document FR-2 819 277, which describes a protection piece intended to be hung from the guardrail consisting basically of two adjacent tubes, according to the vertical direction, fixed to supports provided with openings for fitting the pipes.
  • this configuration from two tubes presents several drawbacks, namely that the kinetic energy of the motorist's body is sufficient to deform the tubes so that it ends up passing through the space between both. It may also happen that the rider hits above the horizontal mid-plane of the upper tube or below the lower one, so that the rider ends up slipping under the element or passes between the guardrail and the upper tube.
  • the element is destined to be fixed directly to the posts by its middle part, which causes that in case of impact, the central fibers remain strained, but not the upper and lower ones, which would allow the body of the rider to pass to the other side.
  • Another example of elements of this type is that described in EP 0 823 511 Al, which is also intended to be fixed to the posts.
  • the profile has a section whose width and height have the same order of magnitude in dimensions.
  • the support is folded from the top to the back, so that the element itself, which can then pass under the body of the injured biker,

  • the combination of the aforementioned characteristics provides an optimal protection element because the flexural resistance means according to the first transverse direction, which is obviously the vertical direction once the element is mounted under the guardrail, and arranged at the lateral ends, in Combination with the air chamber that provides flexibility to the part between said lateral ends, causes the motorist to impact, which in general can occur tangentially, the element adopts a ribbed or stretcher shape, channels it along of the element preventing it from passing to the other side of the guardrail. Being the means of resistance to bending at the ends, they take advantage of the entire width of the element according to the first transverse direction.
  • the presence of the air chamber causes part of the pressure of the motorist to be distributed inside the element, so that the concentration of forces is not so high at the point of impact, as would occur, for example, in elements protectors such as those described in U 1 067 190 and FR 2 556 755.
  • said body comprises holes whose dimensions are selected so that a fraction of the impact energy is dissipated by the exit of part of the chamber air through said holes when a motorist impacts on said larger front surface of the element.
  • holes of the order of 1 cm in section are suitable for providing said energy absorption effect.

  • the element can be mounted so that the ridge overlaps with the lower edge of the guardrail on the side of the road, so that this ridge constitutes a means of transverse retention of the element which also makes it more difficult for the rider's body to pass between the element and the guardrail.

  • said upper extension 2 is provided with grooves or vertical grooves 17 on its two front and rear faces, in order to be able to bend the element, as can be seen in the Figure 16 and allow its adaptation to the contour of the track, especially since the width of the element is greater than the level of the upper extension, as can be seen in Figure 13.

  • said support 101 is characterized by the fact that it comprises a first plate 107 fixing to the post 6, and at least two fixing plates 108, 109 to said element 1, and two arms laminations 110, 111 joining the first plate 107 to each of the fixing plates 108, 109, said arms being folded along an edge along its central part.
  • This structure gives the support 101 a great capacity to absorb the impact energy, since several bending zones are defined whose plastic deformation will absorb part of the impact energy.
  • the three plates 107, 108, 109 and the two laminar arms 110, 111 are obtained by bending a metal sheet, so that almost the entire piece is obtained by simply cutting a material laminate and a folded back. Also, to improve their behavior in the event of an impact, both laminar arms 110, 111 are bent in the same direction.
  • the support bends so that the lower and upper ends follow an approximately horizontal path. This fact is important because it maintains the stability of the protection element, preventing its ends from moving in a vertical direction, which could allow the rider to leave the other side of the element 1 in the direction of the support posts 6.
  • the fixing means comprise a fork 105 whose two free ends 112, 113 cooperate with two holes of said first plate 107, so that by means of two screws the support can be fixed with variable height to a post 6.
  • This feature is especially important because it allows the element 1 to be adjusted in height, and more specifically it allows its lower edge to be approximated to the ground, so that the passage of the body of the motorist below element 1 is avoided, since in the event of a fall, it usually comes sliding down soil.
