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 include at least one smooth 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 space lower under the rail, of sufficient height for a bumpy motorcyclist and sliding on the ground can be seriously injured, either because it gets stuck between the ground and the lower part of the rail, either because it is thrown against the vertical supports located behind the smooth, 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.For these barriers to be protective not only for passenger cars, trucks and coaches, but also for motorcycle users with or without a sidecar, and generally for anyone who accidentally is projected on the taxiway, it is known to fill the space below the 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'entraíne ce type d'écran.But the solutions developed to date have not given satisfaction, particularly because of the rigidity of the proposed screens and fixing difficulties that involves 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, entraíne 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 some urban avenues, visual inconveniences contrary to the search for maintaining the aesthetics of the place by the public, bodies or public authorities.

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 and including screens that can blend into the landscape while ensuring safety of vehicles and especially of 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:
  • Patent 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 can be a vertical screen arranged under the rail. 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 patent 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.
  • EP 1 184 515 in the name of this Applicant describes a safety 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 which are attached to the single smooth 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 the solutions known and offers a screen structure capable of absorbing at least part 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 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 invention relates to a safety barrier intended to be arranged along vehicle traffic routes, comprising, in position of use, at least one horizontal rail subject to vertical supports as well as a lower screen called "protection" intended to oppose the passage under the smooth of a rough user, including two wheels, sliding flat on the track of circulation, the lower protection screen being formed by the longitudinal assembly of horizontal segments, in which each horizontal segment is of structure composite having at least one continuous longitudinal reinforcement combined with at least one slip element sufficiently deformable to absorb at least a portion a shock caused by the user and sufficiently rigid to allow a slip continuous use 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 not include a slide but only a so-called "protection" screen, and this, in the goal of not overloading the figures. For the sake of clarity the structures are exploded to bring out the editing.

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 disposed along vehicle taxiways, includes, in position of use, at least one horizontal rail subject to vertical supports and a lower screen located between the rail and the ground. This screen is especially intended for 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 of horizontal segments located between the vertical supports and generally associated with 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 structure compound and comprises at least one continuous longitudinal reinforcement combined with at least a slip element sufficiently deformable to absorb at least a portion of a shock caused by a user accident and sufficiently rigid 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.FIG. 1 represents a safety barrier comprising a screen 1, in view of an observer lying behind the barrier in relation to the circulation.

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 at a vertical support 100 where two segments horizontal screens 110, 120 are assembled longitudinally, each segment horizontal having two continuous metal longitudinal reinforcements 111, 112 combined with a slip member 113 made from 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 made of synthetic material and more particularly in a plastic of polyethylene type, polypropylene, polyester, polyurethanes, polyvinyl chloride (PVC), 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 have at their ends a 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 face convex 117, 127 in an arc 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 integral with the metal reinforcements respectively 111-112 and 121-122 using 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 amount 100 is obtained by fixing each segment 110, 120 on a junction plate 135, itself coupled to an attachment arm 140 integral with the vertical support 100 via 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 attached to the spreader, the safety screen 1 is suspended under the slide by the arms of fixing 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 in FIG. 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 present only their convex surface 117-127 so that they can overlap to ensure the continuity of 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 are "fish-shell", that is to say that, by reference to the meaning of the circulation, the upstream element covers the downstream element.

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

L'élément de glissement 113 en matière synthétique est profilé pour déterminé une zone bombée déformable.The sliding element 113 made of synthetic material is profiled for determined a curved deformable area.

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.Figure 2bis shows the screen 1 of Figure 2 after a slight impact. The convex portion 117, forming the deformable convex zone of the sliding element plastic 113, curved to the metal reinforcements 118-119 by absorbing the energy of the shock.

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 element of slip plastic 113 is reversible and can return to its original form either automatically, either by a person who pushes it away 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 can be final.

Cette solution est préférée pour éviter le renvoi du motocycliste accidenté sur la voie de circulation.This solution is preferred to avoid the return of the motorcyclist accident on 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 FIG. followed by a step of deformation of the articulated arm, consumer deformation of shock energy.

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 metal reinforcements and the element of non-metallic sliding allows, while keeping a certain flexibility, to prevent the screen 1 does not deform around the vertical supports thus making them prominent in the screen. The damaged vehicle is thus protected from the vertical supports 100 while being accompanied and slowed down along the security fence.

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 rest of the description, a sliding element "no "metal" must be understood as being in material taken from the group 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, a nobody can carry the elements alone and position them while another fixed 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.FIG. 3 represents a screen 2 according to the invention with a view to exploded before, that is to say, from the point of view of an observer placed on the traffic 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.It consists of two horizontal segments 210, 220 each comprising a metal reinforcement 211-221 and a sliding element in synthetic material 213-223 and preferably a polyethylene type plastic, polypropylene, polyester, polyurethanes, polyvinyl chloride (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.Metal reinforcements include coupling zones having apertures 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 two segments together horizontal 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 coupling to a fixing arm 240 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 ends facing each other of the two elements of successive longitudinal sliding 210-220 are covered by a material seal synthetic 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 in 215-225 openings metal reinforcements for fixing the seal on horizontal segments and horizontal segments on the mounting plate. Gasket 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'emboítement 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 slip element in is designed to define, on the opposite side of the taxiway, interlocking grooves with the metal reinforcement. This rear profile is clearly visible in Figure 4 which shows a section of 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 shaped to delimit two zones deformable convex bulbs 255, convex towards the taxiway, each presenting a 256 and a leading edge 257. These curved zones 255 are joined by their front edge 257 to a substantially vertical core 258 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 driving lane, the sliding element 223 has two coplanar vertical walls 259 facing each other and joining each the rear edge 256 of a bulging 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'emboítement de l'élément de glissement 223 avec le renfort métallique 221.Two walls 260 each join the front edge 257 of the parts curved 255 and the vertical walls 259 delimiting between them and the walls 259, a space 261 sufficient to receive the vertical reinforcement 221 and the block. These spaces 261 are nesting grooves of the element of sliding 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 element of sliding 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, so 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 part of the sliding element 223 participates in the absorption of least part 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 absorbing at least a portion of the shock 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 form or to obtain curved portions 255 whose deformation is final.

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

Chaque segment horizontal 310-320 comprend trois éléments de glissement 311, 312, 313 et 321, 322, 323, emboítables et associés à un renfort métallique 314-324.Each horizontal segment 310-320 has three elements of sliding 311, 312, 313 and 321, 322, 323, nestable and associated with a reinforcement metal 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 6, the elements 311, 312 (respectively 321, 322) are each associated with the metal reinforcement 314 (respectively 324) via grooves 315 arranged on the face of the sliding elements 311, 312 (respectively 321, 322) opposite to the taxiway.

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 together by a third central sliding member 313 (respectively 323).

Ces trois éléments 311, 312, 313 (respectivement 321, 322, 323) présentent en coupe des structures de griffe d'emboítement 316-317 complémentaires pour le couplage.These three elements 311, 312, 313 (respectively 321, 322, 323) present in section complementary 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'emboítement 316 de l'élément 313 avec les structures d'emboítement 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 it, 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 aligning one of the lateral ends of the element 313 with the opposite lateral end of the elements 311, 312 to engage the structures 316 of the element 313 with the elements nesting structures 311, 312. The metal reinforcement assembly 314 and sliding elements 311, 312, 313 is then associated with a fixing plate 335 itself to be secured to a fixing arm on a vertical support (not shown). The junction of two successive horizontal segments is covered with a 350 joint.

Une telle structure permet, en cas de choc, de ne changer que les éléments de glissement abímés. 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 makes it possible, in case of shock, to change only the sliding elements abímés. For example, if a vehicle rubs the screen 3, only the outermost sliding element will be damaged, namely 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'emboítement 316-317. Puis les opérations de montage sont effectuées avec un élément de glissement 313 neuf.For replacement, simply remove the seals located on each side and slide the element 313 to one side in order to disengage the elements interlocking 316-317. Then the editing operations are performed with a slip element 313 new.

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 traffic way. The space between the sliding elements 311, 312, 313 and the metal reinforcement 314 allows the sliding elements to deform (FIG. 6a) by absorbing at least part 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 sliding elements deformable with at least one metal reinforcement provides a screen sufficiently strong to protect a damaged two-wheeled vehicle and / or its vertical supports while absorbing at least a portion of the energy of the 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 may be of a structure such that it alone, it would be too weak to play its role of protection because it would deform against the supports, whereas in combination with non-slip elements deformable metal, the resulting screen 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) absorbs (part of) the energy by its (their) deformation property and stiffens the metallic reinforcement (s) in the coupling zone.

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 reinforcement (s) metal (s) by their plastic deformation (that is to say without return to the original form) prevents the expression of the own elasticity non-metallic sliding element (s) and thus avoids repelling the person and / or motorcycle accident on the taxiway.

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 enhanced when the screen is suspended at the safety barrier by deformable arms, absorbing themselves at least one part of the shock energy.

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, according to the invention and represented in Figures 7 and following, consists in that each horizontal segment comprises at least one metal reinforcement combined with at least one sliding in wood.

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 FIG. 7 consists of two horizontal segments 410, 420 comprising a metal reinforcement 411, 421 and a sliding element in wood consisting of a wooden panel 412, 422 of substantially the same length and same height as the metal reinforcement 411, 421. The screen 4 is attached to the supports vertically in the same way 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 the metal reinforcements have each one of a thickness such that, by themselves, they would be insufficient to ensure the vehicle protection as they would become deformed.

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 sufficiently flexible to cushion a 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 FIGS. 8 and 9, two ends facing each other horizontal segments 410, 420 are covered by a joint.

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 FIG. 8 consists of a plate that can be metal, wood or synthetic material. This seal 450 has openings 451 to be placed next to openings 415-425 metal reinforcements for fixing the seal 450 on the horizontal segments 410, 420 and segments 410, 420 on the mounting plate 452. The seal 450 covers the elements of sliding 412-422 associated with metal reinforcements 411-420, the whole being coupled to the attachment plate 452 via 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. The seal 460 of Figure 9 consists of two parallel plates may be metal, of wood or synthetic material, connected by a partition central perpendicular whose length is substantially equal to the thickness of 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 joint 460. These have openings 461 to be placed opposite apertures 415-425 of the horizontal segments 410, 420 for fixing the seal 450 on the horizontal segments 410, 420, and segments horizontal 410, 420 on the fixing 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 Figure 10 is that each horizontal segment of a screen 5 comprises a vertical metal blade 511, 521 and two wooden sliding elements 512, 522 each consisting of a cleat of circular wood 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 attached to the vertical supports in the same way 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 means of 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 edges and lower parts of the metal reinforcement 511, 521 to prevent the shock from being deformed too much and no longer protects the vehicle against 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 can be deformed at its center to absorb at least part of a shock, but does not deform on its edges upper and lower to avoid winding the screen around the supports vertical.

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, all the safety barriers for taxiway previously described allow to absorb at least a portion of the energy of a shock by deforming the composite structure screen while retaining its protective properties.
