Definitions

  • the invention relates to the technical sector of guardrails for motor vehicles intended to be positioned along circulation.
  • a guardrail in a manner perfectly known to those skilled in the art, includes a rail attached to poles supported by usually via spreading members.
  • the different smooth ones are assembled together by any known and appropriate means, so as to constitute a linear assembly arranged along the taxiway and intended to stop vehicles.
  • the smooth can be made from logs of wood or metal profiles.
  • the rails made from metal profiles consist of usually in the form of two parallel waves joined by a part median and are intended to be laid along the traffic lanes of roads or highways where traffic is considered important.
  • These smooth, arranged on the support posts in combination with the organs spreaders, are positioned at a height and at a certain distance from the lane, according to pre-established standards to try to stop light vehicles in the best conditions.
  • These rails for slides may be a satisfactory solution for retaining Light vehicles. However, a problem may arise to retain heavy vehicles.
  • the aim of the invention is to remedy these drawbacks, simple, safe, effective and rational way.
  • the problem that the invention proposes to solve is to be able to ensure the restraint of vehicles, not just light vehicles, but also heavy vehicles, using as much as possible the effect known by the person skilled in the art by the name of a cable or belt effect, namely that under the effect of shock, occurs the phenomenon of unbuttoning the element of slip considered, that is to say that it remains at a height substantially constant so that said slip element considered remains always in contact with the vehicle, to ensure maximum restraint.
  • a retainer for a guardrail of the type comprising, in a perfectly well-known way, a base smooth made integral with support poles, particularly via spacers.
  • the device includes, above the sill of base, another smooth solidarity elements supportable to be coupled, with breaking capacity under the effect of a shock, at the upper end of arms capable of being engaged in the internal section of the posts, with capacity upward movement under the effect of said shock.
  • the top rail fits into the bodywork said vehicle under a pushing force, so that, in a manner concomitantly, the arms tend to slide upwards, while the support elements of the upper arm are disengaged from said arms allowing the top rail to stay at the correct height while the support post or poles of the base rail lie down while being crushed by the wheels of the vehicle.
  • the upper slide fills the desired cable or strap effect by absorbing a maximum energy.
  • the arms are profiled to position the top rail in a staggered way back from the rail of base, the offset being considered from the taxiway.
  • the coupling means of the support elements are constituted by key breakable under the effect of the shock.
  • the support elements are constituted by sleeves fitted at the upper end of the arms.
  • the arms have support arrangements co-operating with the fixing the spacers.
  • the arrangements consist of tabs reported.
  • the arms are constituted by the alignment of several rectilinear segments arranged angularly to allow the shift back of the upper rail.
  • the upper rail is shaped to present a superior resistance to that of the lower rail.
  • the length of the arms and elements supports is determined to position the top rail at a height standardized for a heavy vehicle.
  • a guardrail especially for the restraint of vehicles, includes a base rail (1) fixed on support posts (2) via spreader members (3).
  • the arm (1) is constituted by a metal section delimiting transversely two parallel waves (1a) and (1b) joined by a part ses (1c).
  • Fixing the healds (1) on the spreader members (3) and the fixing the spreader members (3) on the posts (2), is carried out by all known and appropriate means, for example by means of a system of bolts (4) and (5).
  • the support posts (2) are constituted by irons cross-section profiles whose parallel wings are bent for constitute a substantially closed cross section.
  • the retaining device comprises, above the base rail (1), upper rail (6) integral with support elements (7) capable of being coupled, with breaking capacity under the effect of shock, to the upper arm end (8).
  • the link arms (8) cooperate with the support posts (2) while being held in position while having the capacity to be moved upwards under the effect of a shock, as will be indicated in the following description.
  • the support elements (7) consist of sleeves fixed on the top rail (6) by means for example of assembly members of the type bolts (9). These sleeves (7) are fitted at the upper end of the connecting arm (8).
  • the breakable connection between the sleeves (7) and the arms of connection (8) is effected by keys (10) housed in lights that present, in correspondence, said sleeves and said connecting arms.
  • the connecting arms (8) are profiled to position the rails (6) in a manner offset backwards relative to the rails of base (1), this offset being considered from the taxiway.
  • the upper rails are arranged in a plane shifted in back to that containing the base rails (1).
  • the link arms (8) are, for example, freely engaged in the internal section of the support posts (8), while being kept high by arrangements (11) adapted to cooperate with the fastening members (5) of spreaders (3).
  • these arrangements (11) consist of inserts, particularly by welding, at the front of the arms link (8).
  • the connecting arms (8) can be constituted by the alignment of a plurality of rectilinear segments (8a), (8b), (8c) arranged angularly for allow in particular the shift back of the top rail (6) by compared to the base stringer (1), as previously indicated.
  • each link arm may be constituted by a vertical base segment (8a) extended by a rectilinear segment (8b) tilted back and terminated by a rectilinear segment (8c) arranged substantially parallel to the segment rectilinear base (8a) or slightly inclined, to tilt, in a manner corresponding downwards, the top rail (6).
  • the upper beam (6) is shaped to present a higher resistance than that of the base rail (1).
  • this smooth upper (6) is made of thicker steel or larger resistance, or to present, transversely, several wave profiles.
  • the upper beam (6) has wave profiles terminals (6a) and (6b) recognized for a section wave profile (6c) substantially flat from which the support sleeves are fixed (7) via the connecting members (8).
  • the operation of this restraint is as follows.
  • the restraint of light vehicles is carried out in a conventional manner by via the base rail (1).
  • the base rail (1) At the moment of impact of a vehicle heavy with the top rail (6), the latter fits into the bodywork of the vehicle and is stretched under the effect of the thrust of the latter.
  • the arm link (8) slides upwards with respect to the support posts (2), while the connection piece (s) (7) are disengaged from the arms of link (8).
  • These provisions allow the upper slide to remain at the good height while the support posts of the base rail (1) are lying crushed by the wheels of the vehicle.
  • the upper smooth ensures the desired cable and strap effect, absorbing a maximum energy.
  • the retainer according to the features of the invention may be added, without any difficulty, on any type of guardrails existing and more particularly adapted for vehicle restraint light.
