Description

L'invention se rattache au secteur technique des glissières de sécurité pour véhicules automobiles destinées à être positionnées le long des voies de circulation.The invention relates to the technical sector of guardrails for motor vehicles intended to be positioned along circulation.

D'une manière parfaitement connue pour un homme du métier, une glissière de sécurité comprend une lisse fixée sur des poteaux supports par l'intermédiaire généralement d'organes écarteurs. Les différentes lisses sont assemblées entre elles par tout moyen connu et approprié, de manière à constituer un ensemble linéaire disposé le long de la voie de circulation et destiné à arrêter les véhicules. La lisse peut être réalisée à partir de rondins de bois ou de profilés métalliques.In a manner perfectly known to those skilled in the art, a guardrail 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.

Les lisses réalisées à partir de profilés métalliques sont constituées généralement sous forme de deux ondes parallèles réunies par une partie médiane et sont destinées à être posées le long des voies de circulation de routes ou autoroutes où le trafic est considéré comme important. Ces lisses, disposées sur les poteaux supports en combinaison avec les organes écarteurs, sont positionnées à une hauteur et à une certaine distance de la voie de circulation, en fonction de normes préétablies pour tenter d'arrêter les véhicules légers dans les meilleures conditions. Ces lisses pour glissières de sécurité peuvent constituer une solution satisfaisante pour retenir les véhicules légers. Un problème peut toutefois apparaítre pour retenir des véhicules lourds.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.

Pour tenter d'augmenter la résistance de ce type de glissières, les constructeurs ont proposé d'augmenter le nombre de supports ainsi que le nombre de lisses. Il en résulte des systèmes lourds et coûteux, aussi bien au niveau de leur fourniture que de leur pose. In an attempt to increase the resistance of this type of slide, manufacturers proposed to increase the number of supports as well as the number of smooth. The result is heavy and expensive systems, both at level of their supply than of their pose.

On observe également qu'en fonction de l'importance de la violence du choc que subissent les glissières sous l'effet de l'impact du véhicule, le fonctionnement n'est pas toujours rationnel, la sollicitation des poteaux supports étant trop importante eu égard à l'effort encaissé par les éléments de glissement constitués par les lisses. Sous l'effet de l'impact, souvent les poteaux supports sont écrasés par les roues du véhicule, ce qui a pour conséquence de tirer vers le bas les éléments de glissement à moins que les organes de liaison entre les poteaux supports et les lisses, soient arrachés. Autrement dit, la retenue des véhicules est mal assurée.We also observe that depending on the importance of violence the impact on the slides caused by the impact of the vehicle, the operation is not always rational, solicitation of poles supports being too important in view of the effort made by the elements of sliding constituted by the smooth. Under the impact of the impact, often support posts are crushed by the wheels of the vehicle, which has for consequence of pulling the sliding elements downwards unless the connecting members between the support posts and the rails, are torn off. In other words, the restraint of vehicles is poorly secured.

L'invention s'est fixée pour but de remédier à ces inconvénients, de manière simple, sûre, efficace et rationnelle.The aim of the invention is to remedy these drawbacks, simple, safe, effective and rational way.

Le problème que se propose de résoudre l'invention est de pouvoir assurer la retenue des véhicules, non seulement des véhicules légers, mais également des véhicules lourds, en utilisant le plus possible l'effet connu par l'homme du métier sous le nom d'effet câble ou de courroie, à savoir que sous l'effet du choc, se produit le phénomène de déboutonnage de l'élément de glissement considéré, c'est-à-dire que ce dernier reste à une hauteur sensiblement constante pour que ledit élément de glissement considéré reste toujours en contact avec le véhicule, afin d'assurer au maximum sa retenue.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.

Pour résoudre un tel problème, il a été conçu et mis au point un dispositif de retenue pour glissière de sécurité, du type de celle comprenant, d'une manière parfaitement connue, une lisse de base rendue solidaire des poteaux supports par l'intermédiaire notamment d'écarteurs.To solve such a problem, it was designed and developed 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.

Compte tenu du problème posé de pouvoir également assurer la retenue des véhicules lourds, le dispositif comprend, au-dessus de la lisse de base, une autre lisse solidaire d'éléments supports aptes à être accouplés, avec capacité de rupture sous l'effet d'un choc, à l'extrémité supérieure de bras aptes à être engagés dans la section interne des poteaux, avec capacité de déplacement vers le haut, sous l'effet dudit choc.In view of the problem of being able also to ensure restraint of heavy vehicles, 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.

Compte tenu de ces dispositions, il en résulte que, sous l'effet de l'impact du véhicule lourd, la lisse supérieure s'encastre dans la carrosserie dudit véhicule sous un effort de poussée, de sorte que, d'une manière concomitante, les bras ont tendance à coulisser vers le haut, tandis que les éléments supports de la lisse supérieure sont désolidarisés desdits bras permettant ainsi à la lisse supérieure de rester à la bonne hauteur pendant que le ou les poteaux supports de la lisse de base se couchent en étant écrasés par les roues du véhicule. Il en résulte donc que la glissière supérieure remplit l'effet de câble ou de courroie recherché en absorbant elle-même un maximum d'énergie.In view of these provisions, it follows that, as a result of the impact of the heavy vehicle, 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. As a result, the upper slide fills the desired cable or strap effect by absorbing a maximum energy.

Compte tenu du problème posé à résoudre de retenir notamment les véhicules lourds par la lisse supérieure, les bras sont profilés pour positionner la lisse supérieure d'une manière décalée en arrière par rapport à la lisse de base, le décalage étant considéré à partir de la voie de circulation.In view of the problem of resolving heavy vehicles by the upper arm, 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.

Pour résoudre le problème posé d'assurer le déboutonnage de la lisse supérieure, les moyens d'accouplement des éléments supports sont constitués par des clavettes sécables sous l'effet du choc.To solve the problem posed to ensure the smoothing of the smooth superior, the coupling means of the support elements are constituted by key breakable under the effect of the shock.

Dans une forme de réalisation, les éléments supports sont constitués par des manchons emmanchés à l'extrémité supérieure des bras. In one embodiment, the support elements are constituted by sleeves fitted at the upper end of the arms.

Pour résoudre le problème posé d'assurer le maintien en position des bras, tout en permettant leur coulissement vers le haut sous l'effet d'un choc, les bras présentent des agencements d'appui coopérant avec les organes de fixation des écarteurs. Par exemple, les agencements sont constitués par des pattes rapportées.To solve the problem of ensuring that arms, while allowing them to slide upwards under the effect of a shock, the arms have support arrangements co-operating with the fixing the spacers. For example, the arrangements consist of tabs reported.

Dans une autre forme de réalisation, les bras sont constitués par l'alignement de plusieurs segments rectilignes disposés angulairement pour permettre le décalage en arrière de la lisse supérieure.In another embodiment, the arms are constituted by the alignment of several rectilinear segments arranged angularly to allow the shift back of the upper rail.

Avantageusement, la lisse supérieure est conformée pour présenter une résistance supérieure à celle de la lisse inférieure.Advantageously, the upper rail is shaped to present a superior resistance to that of the lower rail.

Selon une autre caractéristique, la longueur des bras et des éléments supports est déterminée pour positionner la lisse supérieure à une hauteur normalisée correspondant à un véhicule du type poids lourds.According to another characteristic, the length of the arms and elements supports is determined to position the top rail at a height standardized for a heavy vehicle.

L'invention est exposée ci-après plus en détail à l'aide des figures des dessins annexés dans lesquels :

  • la figure 1 est une vue à caractère purement schématique montrant une glissière de sécurité équipée du dispositif de retenue des véhicules lourds notamment, selon les caractéristiques de l'invention ;
  • la figure 2 est, à une échelle plus importante, une vue en coupe considérée selon la ligne 2-2 de la figure 1 ;
  • la figure 3 est une vue de face correspondant à la figure 2, la lisse supérieure n'étant pas représentée pour faciliter la lecture des dessins.
The invention is described below in more detail with reference to the figures of the accompanying drawings, in which:
  • Figure 1 is a purely schematic view showing a guardrail equipped with heavy vehicle restraint including, according to the features of the invention;
  • Figure 2 is, on a larger scale, a sectional view taken along the line 2-2 of Figure 1;
  • Figure 3 is a front view corresponding to Figure 2, the upper rail is not shown to facilitate reading of the drawings.

D'une manière parfaitement connue, une glissière de sécurité, notamment pour la retenue des véhicules, comprend une lisse de base (1) fixée sur des poteaux supports (2) par l'intermédiaire d'organes écarteurs (3). La lisse (1) est constituée par un profilé métallique délimitant transversalement deux ondes parallèles (1a) et (1b) réunies par une partie commune (1c). La fixation des lisses (1) sur les organes écarteurs (3) et la fixation des organes écarteurs (3) sur les poteaux (2), s'effectue par tout moyen connu et approprié, par exemple au moyen d'un système de boulons (4) et (5). Généralement, les poteaux supports (2) sont constitués par des fers profilés de section transversale dont les ailes parallèles sont recourbées pour constituer une section transversale sensiblement fermée.In a perfectly known manner, 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 commune (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). Generally, the support posts (2) are constituted by irons cross-section profiles whose parallel wings are bent for constitute a substantially closed cross section.

Selon l'invention, le dispositif de retenue comprend, au-dessus de la lisse de base (1), une lisse supérieure (6) solidaire d'éléments supports (7) aptes à être accouplés, avec capacité de rupture sous l'effet de choc, à l'extrémité supérieure de bras (8). Les bras de liaison (8) coopèrent avec les poteaux supports (2) en étant maintenus en position tout en ayant la capacité d'être déplacés vers le haut sous l'effet d'un choc, comme il sera indiqué dans la suite de la description.According to the invention, 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.

Les éléments supports (7) sont constitués par des manchons fixés sur la lisse supérieure (6) au moyen par exemple d'organes d'assemblage du type boulons (9). Ces manchons (7) sont emmanchés à l'extrémité supérieure des bras de liaison (8). La liaison sécable entre les manchons (7) et les bras de liaison (8) s'effectue par des clavettes (10) logées dans des lumières que présentent, en correspondance, lesdits manchons et lesdits bras de liaison.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.

Les bras de liaison (8) sont profilés pour positionner les lisses supérieures (6) d'une manière décalée en arrière par rapport aux lisses de base (1), ce décalage étant considéré à partir de la voie de circulation. Autrement dit, les lisses supérieures sont disposées dans un plan décalé en arrière par rapport à celui contenant les lisses de base (1).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. In other words, the upper rails are arranged in a plane shifted in back to that containing the base rails (1).

Les bras de liaison (8) sont, par exemple, engagées librement dans la section interne des poteaux supports (8), en étant maintenus en hauteur par des agencements (11) aptes à coopérer avec les organes de fixation (5) des écarteurs (3). Par exemple, ces agencements (11) sont constitués par des pattes rapportées, notamment par soudure, au niveau de la face avant des bras de liaison (8). Ces dispositions permettent donc d'assurer le blocage en hauteur des bras de liaison (8), tout en permettant leur déplacement en direction du haut sous l'effet de chocs. On observe également qu'après avoir convenablement déterminé le positionnement des agencements d'appuis (11) par rapport à la lisse supérieure (6), cette dernière sera convenablement positionnée par rapport à la lisse de base (1) compte tenu du positionnement des organes écarteurs par les organes d'assemblage (5).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). For example, these arrangements (11) consist of inserts, particularly by welding, at the front of the arms link (8). These provisions therefore make it possible to ensure height of the connecting arms (8), while allowing their movement in direction of the top under the effect of shocks. We also observe that after suitably determined positioning of support arrangements (11) relative to the top rail (6), the latter will be suitably positioned relative to the base rail (1) given the positioning spreading members by the connecting members (5).

Les bras de liaison (8) peuvent être constitués par l'alignement de plusieurs segments rectilignes (8a), (8b), (8c) disposés angulairement pour permettre notamment le décalage en arrière de la lisse supérieure (6) par rapport à la lisse de base (1), comme indiqué précédemment. Par exemple, chaque bras de liaison peut être constitué par un segment de base vertical (8a) prolongé par un segment rectiligne (8b) incliné en arrière et terminé par un segment rectiligne (8c) disposé sensiblement parallèlement au segment rectiligne de base (8a) ou légèrement incliné, pour incliner, d'une manière correspondante en direction du bas, la lisse supérieure (6).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. For example, 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).

Avantageusement, la lisse supérieure (6) est conformée pour présenter une résistance supérieure à celle de la lisse de base (1). Par exemple, cette lisse supérieure (6) est réalisée dans un acier plus épais ou de plus grande résistance, ou bien présenter, transversalement, plusieurs profils d'ondes. Selon l'exemple illustré, la lisse supérieure (6) présente des profils d'ondes d'extrémité (6a) et (6b) reconnus pour un profil d'ondes (6c) de section sensiblement méplate à partir de laquelle sont fixés les manchons supports (7) par l'intermédiaire des organes de liaison (8).Advantageously, the upper beam (6) is shaped to present a higher resistance than that of the base rail (1). For example, this smooth upper (6) is made of thicker steel or larger resistance, or to present, transversely, several wave profiles. According to the illustrated example, 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).

Le fonctionnement de ce dispositif de retenue est le suivant. La retenue des véhicules légers s'effectue d'une manière classique par l'intermédiaire de la lisse de base (1). Au moment de l'impact d'un véhicule lourd avec la lisse supérieure (6), cette dernière s'encastre dans la carrosserie du véhicule et se tend sous l'effet de la poussée de ce dernier. Le ou les bras de liaison (8) coulisse(nt) vers le haut par rapport aux poteaux supports (2), tandis que la ou les pièces de raccordement (7) se désolidarisent des bras de liaison (8). Ces dispositions permettent à la glissière supérieure de rester à la bonne hauteur pendant que les poteaux supports de la lisse de base (1) sont couchés en étant écrasé par les roues du véhicule. La lisse supérieure assure donc l'effet de câble et de courroie recherché, en absorbant un maximum d'énergie.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). 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.

Le dispositif de retenue selon les caractéristiques de l'invention peut être rajouté, sans aucune difficulté, sur tout type de glissières de sécurité existantes et plus particulièrement adaptés pour la retenue des véhicules légers.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.

Les avantages ressortent bien de la description.The advantages are apparent from the description.
