Abstract

The barrier has a horizontal side rail subjected to vertical supports. A lower protecting screen is formed by assembling horizontal segments (110, 120) situated between the supports. The screen slides on a traffic lane. Each segment is of composite structure, and comprises two longitudinal reinforcements (111, 112) combined with a non metallic and deformable sliding unit (113).

Description

La présente invention concerne les barrières de sécurité qui sont placées le long de voies de circulation de véhicules et qui comprennent au moins une lisse parallèle au sol, des supports verticaux et un écran de protection.The present invention relates to safety barriers which are placed along vehicle taxiways and which comprise at least one rail parallel to the ground, vertical supports and a protective screen.

Ces barrières ont pour inconvénient de laisser subsister un espace inférieur sous la lisse, de hauteur suffisante pour qu'un motocycliste accidenté et glissant sur le sol puisse être gravement blessé, soit parce qu'il se coince entre le sol et la partie inférieure de la lisse, soit parce qu'il est projeté contre les supports verticaux situés derrière la lisse, supports qui sont nombreux, rigides et contondants c'est-à-dire extrêmement dangereux.These barriers have the disadvantage of leaving a lower space under the rail, of sufficient height that a motorcyclist injured and slipping on the ground can be seriously injured, either because it gets stuck between the ground and the bottom of the smooth, either because it is projected against the vertical supports located behind the rail supports that are numerous, rigid and blunt that is to say extremely dangerous.

Pour que ces barrières soient protectrices non seulement pour les passagers de voitures, camions et autocars, mais aussi pour les usagers de motos avec ou sans side-car, et d'une manière générale pour toute personne qui, accidentellement, est projetée sur la voie de circulation, il est connu de combler l'espace inférieur au moyen d'un écran plan, formé de plaques fixées bout à bout.So that these barriers are not only protective for the passengers of cars, trucks and coaches, but also for the users of motorcycles with or without a sidecar, and in a general way for any person who, accidentally, is projected on the way In circulation, it is known to fill the lower space by means of a flat screen formed of plates fixed end to end.

Mais les solutions développées jusqu'à ce jour n'ont pas donné entière satisfaction, notamment en raison de la rigidité propre aux écrans proposés et des difficultés de fixation qu'entraîne ce type d'écran.But the solutions developed to date have not been entirely satisfactory, especially because of the rigidity of the proposed screens and fixing difficulties that entails this type of screen.

En outre, la présence d'équipements de sécurité dans certains lieux tels que des voies sur berge, des forêts ou certaines avenues urbaines, entraîne des désagréments visuels contraires à la recherche du maintien de l'esthétique du lieu par le public, les organismes ou les pouvoirs publics.In addition, the presence of safety equipment in certain places such as riverbanks, forests or certain urban avenues, causes visual inconveniences contrary to the search for the maintenance of the aesthetics of the place by the public, the organisms or Public powers.

Il est donc important d'obtenir des équipements de sécurité et notamment des écrans qui peuvent se fondre dans le paysage tout en assurant la sécurité des véhicules et surtout de leurs usagers.It is therefore important to obtain safety equipment, especially screens that can blend into the landscape while ensuring the safety of vehicles and especially their users.

Pour situer l'État de la Technique, on peut citer les documents suivants :

  • Le brevet FR 2 556 755 qui décrit une pièce intermédiaire placée entre la lisse et chaque support vertical, bien connue en soi sous le nom de « écarteur », et qui se distingue des pièces courantes en ce qu'elle possède des « moyens de montage pouvant être un écran vertical disposé sous la lisse.
    Cette solution est à exclure car les moyens de montage sont essentiellement des trous devant recevoir des boulons, et ces trous dégradent les caractéristiques mécaniques de l'écarteur.
  • Le brevet FR 2 751 998 vise notamment à « arrêter un motard après une chute », et est constitué par l'assemblage de pièces en caisson devant entourer les supports verticaux d'une barrière de sécurité et réunies par des tiges métalliques horizontales.
    Ces caissons sont d'un prix très élevé car il faut assembler les caissons sur place, et le résultat obtenu est pratiquement inutilisable en raison des caractéristiques mécaniques de ce dispositif qui est loin d'amortir les chocs : les caissons en matière synthétique présentent une élasticité propre et les tiges métalliques horizontales sont en appui sur les supports verticaux rendant cet ensemble est très rigide. En conséquence, un objet projeté contre ce dispositif rebondit vers la voie de circulation lorsque le choc n'est pas trop important et s'écrase contre l'ensemble tige - support lorsque le choc est violent.
  • Le brevet EP 1 184 515 au nom de la présente Déposante décrit une barrière de sécurité dont l'écran de protection est relié à la barrière uniquement en étant suspendu par des bras qui s'étendent au-dessus du bord supérieur de l'écran et qui sont fixés à la lisse unique ou à celle des lisses qui est la plus proche du sol. L'écran s'étend librement, sans aucune autre fixation que celle des bras, lesdits bras étant calibrés pour fléchir non élastiquement et laisser l'écran pivoter avec résistance, sous l'effet d'un choc important. Dans cette barrière de sécurité, seuls les bras absorbent une partie de l'énergie du choc, l'écran ne servant ici que de levier sur les bras.
To situate the state of the art, mention may be made of the following documents:
  • The FR 2,556,755 which describes an intermediate piece placed between the rail and each vertical support, well known per se under the name of "spacer", and which differs from the current parts in that it has "mounting means that can be a vertical screen arranged under the smooth.
    This solution is to be excluded because the mounting means are essentially holes to receive bolts, and these holes degrade the mechanical characteristics of the spacer.
  • The FR 2 751 998 aims in particular to "stop a motorcyclist after a fall", and is constituted by the assembly of box parts to surround the vertical supports of a safety barrier and joined by horizontal metal rods.
    These boxes are of a very high price because it is necessary to assemble the boxes on site, and the result is practically unusable because of the mechanical characteristics of this device which is far from damping shocks: the boxes made of synthetic material have elasticity clean and horizontal metal rods are supported on the vertical supports making this set is very rigid. As a result, an object thrown against this device bounces back toward the taxiway when the impact is not too great and collapses against the support rod assembly when the impact is violent.
  • The EP Patent 1,184,515 in the name of this Applicant describes a security barrier whose protective screen is connected to the barrier only by being suspended by arms that extend above the upper edge of the screen and are attached to the rail single or smooth which is closest to the ground. The screen extends freely, without any other attachment than that of the arms, said arms being calibrated to bend non-elastically and allow the screen to rotate with resistance, under the effect of a significant shock. In this safety barrier, only the arms absorb some of the energy of the shock, the screen here serving as a lever on the arms.

La présente invention remédie aux inconvénients des solutions connues et propose une structure d'écran apte à absorber au moins une partie du choc par elle-même tout en conservant l'esthétique du lieu où il est disposé.The present invention overcomes the disadvantages of known solutions and provides a screen structure capable of absorbing at least a portion of the shock by itself while retaining the aesthetics of the place where it is arranged.

Plus précisément, l'invention a pour objet une barrière de sécurité destinée à être disposée le long de voies de circulation de véhicules, comprenant, en position d'utilisation, au moins une lisse horizontale assujettie à des supports verticaux ainsi qu'un écran inférieur dit " de protection " destiné à s'opposer au passage sous la lisse d'un usager accidenté, notamment de deux roues, glissant à plat sur la voie de circulation, l'écran inférieur de protection étant formé par l'assemblage longitudinal de segments horizontaux, dans lequel chaque segment horizontal est de structure composite comportant au moins un renfort longitudinal continu combiné à au moins un élément de glissement suffisamment déformable définitivement pour absorber au moins une partie d'un choc provoqué par l'usager et suffisamment rigide pour permettre un glissement continu de l'usager.More specifically, the subject of the invention is a safety barrier intended to be arranged along vehicle taxiways, comprising, in the use position, at least one horizontal rail subject to vertical supports as well as a lower screen. said "protection" intended to oppose the passage under the smooth of a user accident, including two wheels, sliding flat on the taxiway, the lower protection screen being formed by the longitudinal assembly of segments horizontal, in which each horizontal segment is of composite structure comprising at least one continuous longitudinal reinforcement combined with at least one slip element sufficiently permanently deformable to absorb at least a portion of a shock caused by the user and sufficiently rigid to allow a continuous sliding of the user.

Dans l'ensemble des figures, les barrières de sécurité présentées ne comportent pas de glissière mais seulement un écran dit « de protection », et ce, dans le but de ne pas surcharger les figures. Dans un souci de clarté les structures sont éclatées afin de faire ressortir le montage.In all the figures, the safety barriers presented do not include a slide but only a screen called "protection", and this, in order not to overload the figures. For the sake of clarity the structures are exploded to bring out the assembly.

En réalité, une barrière de sécurité selon l'invention et destinée à être disposée le long de voies de circulation de véhicules, comprend, en position d'utilisation, au moins une lisse horizontale assujettie à des supports verticaux ainsi qu'un écran inférieur situé entre la lisse et le sol. Cet écran est notamment destiné à s'opposer au passage sous la lisse d'un usager de deux roues accidenté, glissant à plat sur la voie de circulation. L'écran inférieur de protection est formé par l'assemblage longitudinal de segments horizontaux situés entre les supports verticaux et généralement associés sur lesdits supports.In reality, a safety barrier according to the invention and intended to be arranged along vehicle taxiways, comprises, in the use position, at least one horizontal rail subject to vertical supports and a lower screen located between the rail and the ground. This screen is particularly intended to oppose the passage under the smooth of a user of two wheels accident, sliding flat on the taxiway. The lower protection screen is formed by the assembly longitudinal of horizontal segments located between the vertical supports and generally associated on said supports.

Selon l'invention, chaque segment horizontal est de structure composite et comporte au moins un renfort longitudinal continu combiné à au moins un élément de glissement suffisamment déformable pour absorber au moins une partie d'un choc provoqué par un usager accidenté et suffisamment rigide pour permettre un glissement continu de l'usager, c'est-à-dire sans rencontrer d'obstacle saillant dans l'écran tel qu'un support vertical.According to the invention, each horizontal segment is of composite structure and comprises at least one continuous longitudinal reinforcement combined with at least one sliding element sufficiently deformable to absorb at least a portion of a shock caused by a user accidentally and rigid enough to allow a continuous sliding of the user, that is to say without encountering a salient obstacle in the screen such as a vertical support.

La figure 1 représente une barrière de sécurité comportant un écran 1, en vue d'un observateur se situant derrière la barrière par rapport à la voie de circulation.The figure 1 represents a safety barrier comprising a screen 1, for an observer located behind the barrier relative to the traffic lane.

La vue se situe au niveau d'un support vertical 100 où deux segments horizontaux 110, 120 d'écrans sont assemblés longitudinalement, chaque segment horizontal comportant deux renforts longitudinaux continus métalliques 111, 112 combinés à un élément de glissement 113 en matière prise dans le groupe constitué par les matières synthétiques, les matières composites, le bois et les combinaisons de ces matières.The view is located at a vertical support 100 where two horizontal segments 110, 120 of screens are assembled longitudinally, each horizontal segment comprising two continuous metal longitudinal reinforcements 111, 112 combined with a sliding element 113 of material taken in the group consisting of synthetic materials, composite materials, wood and combinations of these materials.

Le premier segment 110 de structure composite comporte deux renforts métalliques 111, 112, et un élément de glissement 113 en matière synthétique et plus particulièrement en un plastique de type polyéthylène, polypropylène, polyester, polyuréthanes, chlorure de polyvinyle (PVC), etc.The first segment 110 of composite structure comprises two metal reinforcements 111, 112, and a sliding element 113 of synthetic material and more particularly of a plastic of the polyethylene, polypropylene, polyester, polyurethane, polyvinyl chloride (PVC) type, etc.

Le deuxième segment 120 de structure composite comprend deux renforts métalliques 121, 122 et un élément de glissement 123 de même matière que l'élément 113 du premier segment 110.The second segment 120 of composite structure comprises two metal reinforcements 121, 122 and a sliding element 123 of the same material as the element 113 of the first segment 110.

Les renforts métalliques 111, 112, 121 et 122 sont, par exemple, des plaques d'acier galvanisé d'épaisseur 2 millimètres, de largeur 250 millimètres et de longueur adaptée à la configuration du terrain. Ils comportent à leurs extrémités un passage oblong respectivement 115, 116, 125 et 126.The metal reinforcements 111, 112, 121 and 122 are, for example, galvanized steel plates of thickness 2 millimeters, width 250 millimeters and length adapted to the terrain configuration. They comprise at their ends an oblong passage respectively 115, 116, 125 and 126.

Les éléments de glissement 113, 123 sont constitués d'une face convexe 117, 127 en arc de cercle présentant deux extrémités, chacune solidaires d'une face plane 118, 119, 128, 129. En position d'utilisation, ces faces planes 118, 119, 128, 129 sont verticales et appliquées contre les renforts métalliques 111, 112, 121 et 122.The sliding elements 113, 123 consist of a convex face 117, 127 in an arc of circle having two ends, each integral with a planar face 118, 119, 128, 129. In the position of use, these planar faces 118, 119, 128, 129 are vertical and applied against the metal reinforcements 111, 112, 121 and 122.

Les éléments de glissement 113, 123 sont solidarisés avec les renforts métalliques respectivement 111-112 et 121-122 à l'aide de boulons 130.The sliding elements 113, 123 are secured to the metal reinforcements 111-112 and 121-122, respectively, by means of bolts 130.

L'assemblage des deux segments horizontaux 110 et 120 sur le montant vertical 100 est obtenu par la fixation de chaque segment 110, 120 sur une plaque de jonction 135, elle même couplée à un bras de fixation 140 solidaire du support vertical 100 par l'intermédiaire d'un écarteur 145.The assembly of the two horizontal segments 110 and 120 on the vertical upright 100 is obtained by fixing each segment 110, 120 on a junction plate 135, itself coupled to an attachment arm 140 secured to the vertical support 100 by the intermediate of a spacer 145.

La glissière de sécurité (non représentée) devant être fixée à l'écarteur, l'écran de sécurité 1 est suspendu sous la glissière par les bras de fixation 140.The guardrail (not shown) to be fixed to the spacer, the safety screen 1 is suspended under the slide by the attachment arms 140.

Comme illustré sur la figure 1, les éléments de glissement 113, 123 présentent une zone Zr de recouvrement située en regard de la plaque de jonction 135.As illustrated on the figure 1 , the sliding elements 113, 123 have a zone Zr of overlap located opposite the junction plate 135.

Dans cette zone, les éléments de glissement ne présentent que leur surface convexe 117-127 de telle sorte qu'elles peuvent se chevaucher pour assurer la continuité des éléments de glissement tout le long de la barrière.In this zone, the sliding elements have only their convex surface 117-127 so that they can overlap to ensure the continuity of the sliding elements all along the barrier.

Avantageusement, les différents éléments de glissement se recouvrent en « écaille de poisson », c'est-à-dire que, par référence au sens de la circulation, l'élément amont recouvre l'élément aval.Advantageously, the different sliding elements overlap in "fish scale", that is to say that, with reference to the direction of flow, the upstream element covers the downstream element.

La figure 2 est une vue en coupe de la figure 1 selon la ligne II-II.The figure 2 is a sectional view of the figure 1 according to line II-II.

L'élément de glissement 113 en matière synthétique est profilé pour déterminé une zone bombée déformable.The sliding element 113 of synthetic material is profiled to determine a deformable convex zone.

La figure 2bis représente l'écran 1 de la figure 2 après un choc léger. La partie convexe 117, formant la zone bombée déformable de l'élément de glissement en plastique 113, s'est incurvé vers les renforts métalliques 118-119 en absorbant l'énergie du choc.The figure 2bis represents the screen 1 of the figure 2 after a slight shock. The convex portion 117, forming the deformable convex zone of the plastic slide member 113, curved toward the metal reinforcements 118-119 by absorbing the energy of the impact.

Lorsque le choc n'est pas trop fort, la déformation de l'élément de glissement en plastique 113 est réversible et peut retrouver sa forme d'origine soit automatiquement, soit par une personne qui le repousse manuellement.When the shock is not too strong, the deformation of the plastic sliding element 113 is reversible and can return to its original form either automatically or by a person who pushes it manually.

Selon le plastique utilisé et/ou la violence du choc, la déformation peut être définitive.Depending on the plastic used and / or the violence of the shock, the deformation may be final.

Cette solution est préférée pour éviter le renvoi du motocycliste accidenté sur la voie de circulation.This solution is preferred to avoid returning the injured motorcyclist to the taxiway.

Lorsque le choc est plus fort, l'étape représentée par la figure 2bis est suivie d'une étape de déformation du bras articulé, déformation consommatrice d'énergie du choc.When the shock is stronger, the step represented by the figure 2bis is followed by a deformation step of the articulated arm, energy consuming deformation of the shock.

La combinaison des renforts métalliques et de l'élément de glissement non métallique permet, tout en gardant une certaine souplesse, d'éviter que l'écran 1 ne se déforme autour des supports verticaux les rendant alors saillants dans l'écran. Le véhicule accidenté est ainsi protégé des supports verticaux 100 tout en étant accompagné et ralenti le long de la barrière de sécurité.The combination of the metal reinforcements and the non-metallic sliding element makes it possible, while keeping a certain flexibility, to prevent the screen 1 from being deformed around the vertical supports thus rendering them protruding in the screen. The accident vehicle is thus protected from the vertical supports 100 while being accompanied and slowed down along the safety barrier.

Dans la suite de la description, un élément de glissement « non métallique » doit être compris comme étant en matière prise dans le groupe constitué par les matières synthétiques, les matières composites, le bois et les combinaisons de ces matièresIn the remainder of the description, a "non-metallic" sliding element must be understood as being made of a material made up of the group consisting of synthetic materials, composite materials, wood and combinations of these materials.

Lors du remplacement de segments accidentés d'écran 1, une personne peut transporter seule les éléments et les positionner alors qu'une autre les fixe à la barrière.When replacing rugged screen segments 1, one person can carry the elements on their own and position them while another person attaches them to the barrier.

La figure 3 représente un écran 2 conforme à l'invention en vue éclatée avant, c'est-à-dire du point de vue d'un observateur placé sur la voie de circulation et regardant vers la barrière portant l'écran 2.The figure 3 represents a screen 2 according to the invention in exploded view before, that is to say from the point of view of an observer placed on the taxiway and looking towards the barrier carrying the screen 2.

Celui-ci est constitué de deux segments horizontaux 210, 220 comprenant chacun un renfort métallique 211-221 et un élément de glissement en matière synthétique 213-223 et de préférence en un plastique de type polyéthylène, polypropylène, polyester, polyuréthanes, chlorure de polyvinyle (PVC), etc.This consists of two horizontal segments 210, 220 each comprising a metal reinforcement 211-221 and a sliding element made of synthetic material 213-223 and preferably a plastic of the polyethylene, polypropylene, polyester, polyurethane or polyvinyl chloride type. (PVC), etc.

Les renforts métalliques comprennent des zones de couplages présentant des ouvertures 215-225 à leurs extrémités pour le passage de boulons 252 en vue de leur fixation sur une plaque de fixation 235.The metal reinforcements comprise coupling zones having openings 215-225 at their ends for the passage of bolts 252 for attachment to an attachment plate 235.

Cette plaque 235 solidarise donc ensemble deux segments horizontaux 210-220.This plate 235 thus secures together two horizontal segments 210-220.

Elle comprend en outre une ouverture 236 pour son couplage à un bras de fixation 240 devant lui-même être associé à un support vertical.It further comprises an opening 236 for its coupling to a fixing arm 240 which must itself be associated with a vertical support.

Les deux extrémités en regard l'une de l'autre des deux éléments de glissement longitudinaux successifs 210-220 sont recouvertes par un joint de matière synthétique 250.The two opposite ends of the two successive longitudinal sliding elements 210-220 are covered by a plastics joint 250.

Ce joint 250 présente des ouvertures 251 devant être placées en regard des ouvertures 215-225 des renforts métalliques pour la fixation du joint sur les segments horizontaux et des segments horizontaux sur la plaque de fixation. Le joint 250 recouvre l'élément de glissement 223 associé au renfort métallique 221, l'ensemble étant couplé à la plaque de fixation 235 par l'intermédiaire de boulons 252.This seal 250 has openings 251 to be placed opposite the openings 215-225 metal reinforcements for fixing the seal on the horizontal segments and horizontal segments on the fixing plate. The seal 250 covers the sliding element 223 associated with the metal reinforcement 221, the assembly being coupled to the fixing plate 235 by means of bolts 252.

Dans chaque segment horizontal, l'élément de glissement en matière synthétique est profilé pour délimiter, sur la face opposée à la voie de circulation, des rainures d'emboîtement avec le renfort métallique. Ce profilé arrière est bien visible sur la figure 4 qui représente une coupe de la figure 3 selon la ligne IV-IV.In each horizontal segment, the sliding element of synthetic material is profiled to define, on the opposite side to the traffic lane, interlocking grooves with the metal reinforcement. This rear profile is clearly visible on the figure 4 which represents a section of the figure 3 along line IV-IV.

L'élément de glissement 223 est profilé pour délimiter deux zones bombées déformables 255, convexes vers la voie de circulation, présentant chacune un bord arrière 256 et un bord avant 257. Ces zones bombées 255 sont jointes par leur bord avant 257 à une âme 258 sensiblement verticale en position d'utilisation.The sliding element 223 is profiled to delimit two convex curved zones 255, convex towards the traffic lane, each having a rear edge 256 and a front edge 257. These convex zones 255 are joined by their front edge 257 to a web 258. substantially vertical in use position.

Sur sa face opposée à la voie de circulation, l'élément de glissement 223 présente deux parois verticales coplanaires 259 se faisant face et joignant chacune le bord arrière 256 d'une partie bombée 255.On its opposite side to the traffic lane, the sliding element 223 has two coplanar vertical walls 259 facing each other and each joining the rear edge 256 of a convex portion 255.

Deux parois 260 joignent chacune le bord avant 257 des parties bombées 255 et les parois verticales 259 en délimitant entre elles et les parois verticales 259, un espace 261 suffisant pour recevoir le renfort vertical 221 et le bloquer. Ces espaces 261 constituent des rainures d'emboîtement de l'élément de glissement 223 avec le renfort métallique 221.Two walls 260 each join the front edge 257 of the curved portions 255 and the vertical walls 259 delimiting between them and the vertical walls 259, a space 261 sufficient to receive the vertical reinforcement 221 and block it. These spaces 261 form interlocking grooves of the sliding element 223 with the metal reinforcement 221.

Les rainures 261 permettent une bonne interaction de l'élément de glissement 223 avec le renfort métallique 221 sur toute la surface du renfort 221.The grooves 261 allow a good interaction of the sliding element 223 with the metal reinforcement 221 over the entire surface of the reinforcement 221.

Il est ainsi possible d'employer un renfort métallique peu épais, donc plus léger et moins cher puisqu'il est renforcé et rigidifié par la partie arrière de l'élément de glissement 223. L'écran 2 conserve ainsi les qualités protectrices. La partie avant bombée de l'élément de glissement 223 participe à l'absorption d'au moins une partie du choc.It is thus possible to use a thin metal reinforcement, therefore lighter and cheaper since it is reinforced and stiffened by the rear part of the sliding element 223. The screen 2 thus retains the protective qualities. The convex front portion of the sliding member 223 participates in the absorption of at least a portion of the shock.

En effet, comme le montre la figure 4bis, les espaces situés entre les parties bombées 255 et les parois 260 permettent aux parties bombées de se déformer en absorbant au moins une partie de l'énergie du choc.Indeed, as shown in figure 4bis the spaces between the curved portions 255 and the walls 260 allow the curved portions to deform by absorbing at least a portion of the impact energy.

Ici encore le choix du matériau et de son épaisseur dépend de la volonté d'obtenir des parties bombées 255 pouvant reprendre leur forme initiale ou d'obtenir des parties bombées 255 dont la déformation est définitive.Here again the choice of the material and its thickness depends on the desire to obtain curved portions 255 that can return to their original shape or to obtain curved portions 255 whose deformation is final.

La figure 5 représente un écran 3 constituée de deux segments horizontaux 310-320.The figure 5 represents a screen 3 consisting of two horizontal segments 310-320.

Chaque segment horizontal 310-320 comprend trois éléments de glissement 311, 312, 313 et 321, 322, 323, emboîtables et associés à un renfort métallique 314-324.Each horizontal segment 310-320 comprises three sliding elements 311, 312, 313 and 321, 322, 323, nestable and associated with a metal reinforcement 314-324.

Comme le montre la coupe selon la ligne VI-VI et représentée figure 6, les éléments 311, 312 (respectivement 321, 322) sont associés chacun au renfort métallique 314 (respectivement 324) par l'intermédiaire de rainures 315 ménagées sur la face des éléments de glissement 311, 312 (respectivement 321, 322) opposée à la voie de circulation.As shown by the section along line VI-VI and shown figure 6 the elements 311, 312 (respectively 321, 322) are each associated with the metal reinforcement 314 (respectively 324) via grooves 315 formed on the face of the sliding elements 311, 312 (respectively 321, 322) opposite to the traffic way.

Ces rainures ont une structure semblable à celles décrites dans la figure 4.These grooves have a structure similar to those described in figure 4 .

Les deux éléments de glissement 311, 312 (respectivement 321, 322) sont couplés entre eux par un troisième élément de glissement central 313 (respectivement 323).The two sliding elements 311, 312 (respectively 321, 322) are coupled to each other by a third central sliding element 313 (respectively 323).

Ces trois éléments 311, 312, 313 (respectivement 321, 322, 323) présentent en coupe des structures de griffe d'emboîtement 316-317 complémentaires pour le couplage.These three elements 311, 312, 313 (respectively 321, 322, 323) have in section complementary interlocking claw structures 316-317 for coupling.

Le montage d'un segment horizontal est donc très simple. Pour cela, les éléments de glissement 311-312 sont positionnés sur le renfort métallique 314 et maintenus en place par les rainures 315. L'élément 313 est associé aux éléments 311, 312 en faisant coïncider l'une des extrémités latérales de l'élément 313 avec l'extrémité latérale opposée des éléments 311, 312 afin d'engager les structures d'emboîtement 316 de l'élément 313 avec les structures d'emboîtement des éléments 311, 312. L'ensemble renfort métallique 314 et éléments de glissement 311, 312, 313 est alors associé à une plaque de fixation 335 elle-même devant être solidarisée à un bras de fixation sur un support vertical (non représentés). La jonction de deux segments horizontaux successifs est recouverte d'un joint 350.Mounting a horizontal segment is therefore very simple. For this, the sliding elements 311-312 are positioned on the metal reinforcement 314 and held in place by the grooves 315. The element 313 is associated with the elements 311, 312 by making one of the lateral ends of the element coincide. 313 with the opposite lateral end of the elements 311, 312 to engage the interlocking structures 316 of the element 313 with the interlocking structures of the elements 311, 312. The metal reinforcement assembly 314 and sliding elements 311 , 312, 313 is then associated with a fastening plate 335 itself to be secured to an attachment arm on a vertical support (not shown). The junction of two successive horizontal segments is covered with a joint 350.

Une telle structure permet, en cas de choc, de ne changer que les éléments de glissement abîmés. Par exemple, si un véhicule frotte l'écran 3, seul l'élément de glissement le plus extérieur sera endommagé, à savoir l'élément 313.Such a structure allows, in case of shock, to change only the damaged sliding elements. For example, if a vehicle rubs the screen 3, only the outermost sliding element will be damaged, namely the element 313.

Pour le remplacement, il suffit d'enlever les joints situés de chaque côté et de faire coulisser l'élément 313 vers un côté afin de désengager les éléments d'emboîtement 316-317. Puis les opérations de montage sont effectuées avec un élément de glissement 313 neuf.For replacement, simply remove the seals on each side and slide the element 313 to one side to disengage the interlocking elements 316-317. Then the editing operations are performed with a new sliding element 313.

Un autre avantage d'une telle structure est sa forme bombée vers la voie de circulation. L'espace compris entre les éléments de glissement 311, 312, 313 et le renfort métallique 314 permet aux éléments de glissement de se déformer (figure 6bis) en absorbant au moins une partie du choc.Another advantage of such a structure is its curved shape towards the taxiway. The space between the sliding elements 311, 312, 313 and the metal reinforcement 314 allows the sliding elements to deform ( figure 6bis ) absorbing at least a portion of the shock.

La combinaison d'éléments de glissement non métalliques déformables avec au moins un renfort métallique permet d'obtenir un écran suffisamment résistant pour protéger un véhicule accidenté deux roues et/ou son utilisateur des supports verticaux tout en absorbant au moins une partie de l'énergie du choc.The combination of non-metallic deformable sliding elements with at least one metal reinforcement makes it possible to obtain a sufficiently strong screen to protect a two-wheeled accident vehicle and / or its user from vertical supports while absorbing at least part of the energy shock.

Le renfort métallique utilisé peut être d'une structure telle qu'à lui seul, il serait trop peu résistant pour jouer son rôle de protection car il se déformerait contre les supports, alors qu'en combinaison avec les éléments de glissement non métalliques eux-mêmes déformables, l'écran obtenu protège des supports verticaux et participent à l'absorption du choc.The metal reinforcement used can be of such a structure that it alone would be too weak to play its role of protection because it would deform against the supports, while in combination with the non-metallic sliding elements themselves. deformable, the screen obtained protects vertical supports and participate in the absorption of shock.

Autrement dit, l' (les) élément(s) de glissement non métallique(s) absorbe(nt) une partie de l'énergie par ses(leur) propriété de déformation et rigidifie(nt) le(les) renfort(s) métallique(s) dans la zone de couplage.In other words, the non-metallic sliding element (s) absorb (s) part of the energy by its (their) property of deformation and stiffens (s) the reinforcement (s) metallic (s) in the coupling area.

Le(les) renfort(s) métallique(s) par leur déformation plastique (c'est-à-dire sans retour à la forme initiale) empêche l'expression de l'élasticité propre du(des) élément(s) de glissement non métallique(s) et évite ainsi de repousser la personne et/ou la moto accidentée sur la voie de circulation.The metal reinforcement (s) by their plastic deformation (that is to say without return to the initial shape) prevents the expression of the own elasticity of the sliding element (s) non-metallic (s) and thus avoids pushing the person and / or motorcycle accident on the road.

Cette absorption est encore améliorée lorsque l'écran est suspendu à la barrière de sécurité par des bras déformables, absorbant eux-mêmes au moins une partie de l'énergie du choc.This absorption is further improved when the screen is suspended at the safety barrier by deformable arms, absorbing themselves at least a portion of the energy of the shock.

Un autre mode de réalisation d'un écran, conforme à l'invention et représenté dans les figures 7 et suivantes, consiste à ce que chaque segment horizontal comprend au moins un renfort métallique combiné à au moins un élément de glissement en bois.Another embodiment of a screen, in accordance with the invention and represented in the figures 7 and following, is that each horizontal segment comprises at least one metal reinforcement combined with at least one wooden sliding element.

L'écran 4 de la figure 7 est constitué de deux segments horizontaux 410, 420 comprenant un renfort métallique 411, 421 et un élément de glissement en bois constitué d'un panneau de bois 412, 422 sensiblement de mêmes longueur et de même hauteur que le renfort métallique 411, 421. L'écran 4 est fixé aux supports verticaux de la même manière qu'exposée précédemment pour les autres écrans.Screen 4 of the figure 7 consists of two horizontal segments 410, 420 comprising a metal reinforcement 411, 421 and a wooden sliding element consisting of a wooden panel 412, 422 of substantially the same length and height as the metal reinforcement 411, 421. L Screen 4 is attached to the vertical supports in the same manner as previously explained for the other screens.

Les panneaux de bois 412, 422 et les renforts métalliques présentent chacun une épaisseur telle que, à eux seuls, ils seraient insuffisants pour assurer la protection des véhicules car ils se déformeraient.The wood panels 412, 422 and metal reinforcements each have a thickness such that they alone would be insufficient to protect the vehicles because they would deform.

Mais, associés en combinaison, ils sont suffisamment rigides pour protéger les véhicules des supports verticaux et suffisamment souples pour amortir une partie du choc.But, combined in combination, they are rigid enough to protect vehicles from vertical supports and flexible enough to cushion part of the shock.

Comme illustré dans les figures 8 et 9, deux extrémités en regard l'une de l'autre des segments horizontaux 410, 420 sont recouvertes par un joint.As illustrated in figures 8 and 9 , two ends facing each other horizontal segments 410, 420 are covered by a seal.

Le joint 450 de la figure 8 est constitué d'une plaque pouvant être métallique, en bois ou en matière synthétique. Ce joint 450 présente des ouvertures 451 devant être placées en regard d'ouvertures 415-425 des renforts métalliques pour la fixation du joint 450 sur les segments horizontaux 410, 420 et des segments horizontaux 410, 420 sur la plaque de fixation 452. Le joint 450 recouvre les éléments de glissement 412-422 associés aux renforts métalliques 411-420, l'ensemble étant couplé à la plaque de fixation 452 par l'intermédiaire de boulons 454.The seal 450 of the figure 8 consists of a plate that can be metal, wood or synthetic material. This seal 450 has openings 451 to be placed opposite openings 415-425 metal reinforcements for fixing the seal 450 on the horizontal segments 410, 420 and horizontal segments 410, 420 on the attachment plate 452. The seal 450 covers the sliding elements 412-422 associated with the metal reinforcements 411-420, the assembly being coupled to the fixing plate 452 by means of bolts 454.

Le joint 460 de la figure 9 est constitué de deux plaques parallèles pouvant être métalliques, en bois ou en matière synthétique, reliées par une cloison centrale perpendiculaire dont la longueur est sensiblement égale à l'épaisseur des segments horizontaux 410, 420.Joint 460 of the figure 9 consists of two parallel plates that can be made of metal, of wood or of synthetic material, connected by a perpendicular central partition whose length is substantially equal to the thickness of the horizontal segments 410, 420.

Lors du montage, les segments horizontaux 410, 420 sont insérés entre les deux plaques parallèles du joint 460. Celles-ci présentent des ouvertures 461 devant être placées en regard d'ouvertures 415-425 des segments horizontaux 410, 420 pour la fixation du joint 450 sur les segments horizontaux 410, 420, et des segments horizontaux 410, 420 sur la plaque de fixation 452 par l'intermédiaire de boulons 454.During assembly, the horizontal segments 410, 420 are inserted between the two parallel plates of the seal 460. These have openings 461 to be placed opposite openings 415-425 of the horizontal segments 410, 420 for fixing the seal 450 on the horizontal segments 410, 420, and horizontal segments 410, 420 on the attachment plate 452 by means of bolts 454.

Une autre solution illustrée dans la figure 10 consiste à ce que chaque segment horizontal d'un écran 5 comprend une lame métallique verticale 511, 521 et deux éléments de glissement en bois 512, 522 constitués chacun par un tasseau de bois circulaire comprenant une gorge 525 dans laquelle est inséré un bord de la lame métallique 511, 521.Another solution illustrated in the figure 10 consists in that each horizontal segment of a screen 5 comprises a vertical metal blade 511, 521 and two wooden sliding elements 512, 522 each constituted by a circular wooden cleat comprising a groove 525 in which is inserted an edge of the metal blade 511, 521.

L'écran 5 est fixé aux supports verticaux de la même manière qu'exposée précédemment pour les autres écrans.The screen 5 is fixed to the vertical supports in the same manner as previously exposed for the other screens.

Les tasseaux de bois 512, 522 sont fixés au renfort métallique par des boulons (non représenté).The wooden battens 512, 522 are fixed to the metal reinforcement by bolts (not shown).

Le renfort métallique 511, 521 présente une épaisseur telle qu'il peut se déformer pour absorber au moins une partie d'un choc.The metal reinforcement 511, 521 has a thickness such that it can deform to absorb at least part of a shock.

Les tasseaux de bois 512, 522 rigidifient les bords supérieurs et inférieurs du renfort métallique 511, 521 pour éviter que, lors du choc il ne se déforme trop et ne protège plus le véhicule contre les supports verticaux.The wooden battens 512, 522 stiffen the upper and lower edges of the metal reinforcement 511, 521 to prevent it from being deformed too much during the impact and does not protect the vehicle against the vertical supports.

En conséquence, l'écran 5 peut se déformer en son centre pour absorber au moins une partie d'un choc, mais ne se déforme pas sur ses bords supérieurs et inférieurs pour éviter l'enroulement de l'écran autour des supports verticaux.As a result, the screen 5 may deform at its center to absorb at least a portion of a shock, but does not deform at its upper and lower edges to prevent winding of the screen around the vertical supports.

Ainsi, l'ensemble des barrières de sécurités pour voie de circulation décrites précédemment permettent d'absorber au moins une partie de l'énergie d'un choc par déformation de l'écran de structure composite tout en conservant ses propriétés de protection.Thus, the set of safety barriers for lanes described above allow at least a portion of the energy of a shock to be absorbed by deforming the composite structure screen while maintaining its protective properties.
