Description

La présente invention concerne le domaine des barrières levantes destinées à contrôler le passage sur une voie de circulation.The present invention relates to the field of lifting barriers for controlling the passage on a taxiway.

La présente invention peut trouver de nombreuses applications.The present invention can find many applications.

Les barrières conformes à la présente invention peuvent en particulier être utilisées sur les postes de péage autoroutiers, les accès de parking, etc...The barriers according to the present invention can in particular be used on motorway toll stations, parking access points, etc.

De nombreuses barrières ont déjà été proposées.Many barriers have already been proposed.

Les barrières connues comprennent généralement une lisse comportant une armature en métal, par exemple et le plus souvent en aluminium.Known barriers generally include a rail having a metal frame, for example and usually aluminum.

Le document EP 0886009 décrit une barrière de sécurité, notamment barrière de passage à niveau ou de parking, comportant au moins une lisse pourvue d'au moins un élément conducteur de l'électricité relié à un dispositif permettant de détecter une variation ou une interruption de la continuité électrique de l'élément conducteur, constitué par une boucle conductrice comportant plusieurs brins conducteurs portés par un support fibreux.The document EP 0886009 describes a safety barrier, in particular a crossing barrier or a parking barrier, comprising at least one rail provided with at least one electrically conductive element connected to a device making it possible to detect a variation or interruption in the electrical continuity of the the conductive element, constituted by a conductive loop comprising a plurality of conductive strands carried by a fibrous support.

Une telle barrière permet de détecter lorsque la barrière est endommagée du fait d'une cassure de la lisse, par exemple en raison d'un accident, d'un acte de vandalisme ou encore d'un brusque coup de vent.Such a barrier makes it possible to detect when the barrier is damaged because of a breakage of the rail, for example due to an accident, an act of vandalism or a sudden gust of wind.

Le document divulgue également que la lisse peut être réalisée en matériau composite.The document also discloses that the beam can be made of composite material.

Bien qu'ayant rendu de grands services les lisses connues ne donnent cependant pas toujours totalement satisfaction.Although having rendered great service known smooths do not always give full satisfaction.

En effet les problèmes suivants sont fréquemment signalés :

  • détérioration de véhicules, notamment casse de pare-brise, lors des manoeuvres de fermeture des barrières,
  • blessure de piétons,
  • détérioration des lisses,
  • durée de vie limitée du mécanisme d'entraînement des barrières.
Indeed, the following problems are frequently reported:
  • deterioration of vehicles, in particular windshield breakage, during closing operations of the gates,
  • pedestrian injury,
  • deterioration of the smooth,
  • limited service life of the barrier drive mechanism.

Other features, objects and advantages of the present invention will appear on reading the detailed description which follows and with reference to the appended drawings given by way of non-limiting examples and in which:

On a représenté sur les figures annexées une barrière de sécurité conforme à la présente invention comprenant un barreau ou lisse 100, horizontale au repos, porté par un étrier 200 monté à rotation autour d'un axe horizontal 210 sur une borne 300. L'étrier 200 est entraîné à rotation autour de l'axe 210 par un moteur logé dans la borne 300.The accompanying figures show a safety barrier according to the present invention comprising a bar or smooth 100, horizontal at rest, carried by a stirrup 200 rotatably mounted about a horizontal axis 210 on a terminal 300. The stirrup 200 is rotated about the axis 210 by a motor housed in the terminal 300.

Ainsi en positon de repos, la lisse 100 s'étend horizontalement en travers d'un passage à contrôler, pour interdire un libre passage. Au contraire, après activation du moteur, la lisse est pivotée verticalement vers le haut pour libérer le passage précité.Thus in rest position, the smooth 100 extends horizontally across a passage to control, to prohibit a free passage. On the contrary, after activation of the motor, the arm is pivoted vertically upwards to release the aforementioned passage.

Dans le cadre de la présente invention la lisse 100 est constituée d'un tube central rectiligne 110 de section droite circulaire, en matériau composite, par exemple à base de fibres de verre, de fibres de carbone et de résine époxy.In the context of the present invention, the rail 100 consists of a rectilinear central tube 110 of circular cross-section, made of composite material, for example based on glass fibers, carbon fibers and epoxy resin.

Après de nombreux essais, les inventeurs ont retenu une structure de tube 110 constituée par un ensemble de filés de fibres de carbone et de fibres de verre, enduites de résine époxy polymérisée pour coller les fibres parallèlement les unes aux autres et former ainsi le tube.After numerous tests, the inventors have retained a tube structure 110 consisting of a set of carbon fiber and glass fiber yarns, coated with polymerized epoxy resin to bond the fibers parallel to each other and thus form the tube.

La réalisation du tube 110 formé d'une couche interne 112 de filés de fibres de verre longitudinaux et jointifs d'un poids linéaire compris entre 60 et 70 g/ml, de préférence de 67 g/ml, recouverte d'une hélice 114 de fibres de verre orientée selon un angle compris entre 60 et 80°, de préférence de l'ordre de 75° par rapport à l'axe longitudinal, d'un poids linéaire compris entre 50 et 60 g/ml, de préférence de 52 g/ml, elle-même recouverte d'une couche externe 116 de filés de fibres de carbone longitudinaux et jointifs d'un poids linéaire compris entre 85 et 95 g/ml, de préférence de 90 g/ml, offre une meilleure élasticité et permet d'obtenir une lisse à plus grande flexion, plus tolérante en cas de chocs, tant pour sa durée de vie propre, que sur le plus faible risque à l'égard des véhicules impactant la lisse.The embodiment of the tube 110 formed of an inner layer 112 of longitudinal and contiguous glass fiber yarns with a linear weight of between 60 and 70 g / ml, preferably 67 g / ml, coated with a helix 114 of glass fiber oriented at an angle of between 60 and 80 °, preferably of the order of 75 ° with respect to the longitudinal axis, with a linear weight of between 50 and 60 g / ml, preferably of 52 g. / ml, itself covered with an outer layer 116 of longitudinal and contiguous carbon fiber yarns with a linear weight of between 85 and 95 g / ml, preferably of 90 g / ml, offers a better elasticity and makes it possible to obtain a smooth to greater flexion, more tolerant in case of shocks, both for its own life, and the lowest risk for vehicles impacting the beam.

Plus précisément encore, après de nombreux essais, les inventeurs ont retenu une solution combinant 55 à 65% de fibres de verre, typiquement 57% et 45 à 35%, typiquement 43%% de fibres de carbone pour la réalisation du tube 110.More precisely still, after numerous tests, the inventors have retained a solution combining 55 to 65% of glass fibers, typically 57% and 45 to 35%, typically 43% of carbon fibers for producing the tube 110.

Cette combinaison de filés de fibres de verre sur les couches interne 112 et centrale 114, avec des fibres de carbone sur la couche externe 116, formant une hélice prise en sandwich entre deux couches de filés longitudinaux, alliée à des poids linéaires différents pour les différentes couches, a montré un meilleur compromis en termes de résistance, durée de vie et dégâts occasionnés en cas d'impact, que des solutions comprenant 100% de fibres de carbone ou 100% de fibres de verre.This combination of glass fiber yarns on the internal 112 and central 114 layers, with carbon fibers on the outer layer 116, forming a helix sandwiched between two layers of longitudinal yarns, allied to different linear weights for the different layers, showed a better compromise in terms of strength, durability and impact damage, than solutions comprising 100% carbon fibers or 100% glass fibers.

Ainsi, des crash-tests ont montré que la lisse selon l'invention est capable d'une flexion de +/- 45° par rapport à son axe longitudinal lors de chocs avec une voiture lancée à 60 km/h et de +/- 55° à 80 km/h.Thus, crash tests have shown that the rail according to the invention is capable of a flexion of +/- 45 ° with respect to its longitudinal axis during shocks with a car launched at 60 km / h and +/- 55 ° to 80 km / h.

Pour sa réalisation, le tube 110 est fait par pulltrusion simultanée de filés de fibres de verre jointifs longitudinaux tirés longitudinalement au moyen d'une première filière tandis qu'une seconde filière tournante d'un diamètre supérieur tire en hélice une couche centrale de filés de fibres de verre jointifs et qu'une troisième filière d'un diamètre encore supérieur tire longitudinalement des filés de fibres de carbone jointifs.For its embodiment, the tube 110 is made by simultaneous pulltrusion of longitudinally joined longitudinal glass fiber yarns drawn longitudinally by means of a first die while a second larger diameter rotating die pulls a central layer of yarns of contiguous glass fibers and that a third die of even greater diameter longitudinally pulls contiguous carbon fiber yarns.

Chacune des fibres est recouverte initialement de résine epoxy, celle-ci étant polymérisée lorsque le tube formé de ses trois couches est réalisé, de sorte que l'ensemble des couches forme un tout monobloc.Each of the fibers is initially covered with epoxy resin, the latter being polymerized when the tube formed of its three layers is formed, so that all the layers form a single piece.

Le tube en matériau composite 110 est recouvert par un manchon de protection, par exemple en polystyrène expansé 120. Ce manchon a pour fonction principale d'éviter l'endommagement des véhicules lors de chocs et de protéger le tube 110 composite de toutes les aspérités que peut rencontrer la lisse lors de chocs, (par exemple barres de toit, muret, etc...).The composite material tube 110 is covered by a protective sleeve, for example expanded polystyrene 120. This sleeve has the main function of preventing damage to vehicles during shocks and to protect the composite tube 110 from all the asperities that can meet the smooth during shocks (eg roof bars, low wall, etc ...).

De préférence ce manchon 120 est formé par deux demi coquilles symétriques 122, 124 dont le plan moyen de jonction correspond à un plan diamétral du tube 110, c'est-à-dire un plan passant par l'axe longitudinal du tube 110. Les deux coquilles 122, 124 sont identiques. Chaque demie coquille 122, 124 a une section droite correspondant à une demie couronne. Le manchon 120 s'étend de préférence sur la quasi-totalité de la longueur du tube 110.Preferably this sleeve 120 is formed by two symmetrical half-shells 122, 124 whose average junction plane corresponds to a diametral plane of the tube 110, that is to say a plane passing through the longitudinal axis of the tube 110. two shells 122, 124 are identical. Each half shell 122, 124 has a cross section corresponding to a half crown. The sleeve 120 preferably extends over almost the entire length of the tube 110.

Plus précisément comme on le voit sur les figures 1 et 2 annexées, de préférence les deux demi-coquilles 122 et 124 sont nervurées longitudinalement. Ainsi les deux demi-coquilles 122 et 124 possèdent chacune, au niveau de leur plan de jonction, d'un côté de l'axe longitudinal, une nervure en saillie 121 et de l'autre côté de l'axe longitudinal, une rainure en creux 123, de section droite complémentaire de la nervure 121 précitée, propre à accueillir la nervure en regard de l'autre demi coquille.More precisely as we see on the Figures 1 and 2 appended, preferably the two half-shells 122 and 124 are longitudinally ribbed. Thus the two half-shells 122 and 124 each have, at their junction plane, one side of the longitudinal axis, a projecting rib 121 and on the other side of the longitudinal axis, a groove in hollow 123, of complementary straight section of the aforementioned rib 121, adapted to accommodate the rib facing the other half shell.

L'utilisation de demi- coquille 122, 124 nervurées permet de renforcer le maintien du manchon 120 sur le tube 110, y compris lors des déformations subies à l'occasion de chocs.The use of ribbed half-shell 122, 124 makes it possible to reinforce the retention of the sleeve 120 on the tube 110, including during the deformations undergone during shocks.

Le manchon peut être maintenu sur le tube central 110 par tous moyens appropriés, par exemple par collage, avantageusement à l'aide d'une colle silicone.The sleeve may be held on the central tube 110 by any appropriate means, for example by gluing, preferably with a silicone glue.

De préférence le manchon 120 est lui-même recouvert par une gaine 130 ayant pour fonction de maintenir en place les éléments composant le manchon 120 en polystyrène, même en cas de détérioration de celui-ci. La gaine 130 est avantageusement formée d'une gaine en polyéthylène (PE) thermorétractable.Preferably the sleeve 120 is itself covered by a sheath 130 whose function is to hold in place the components of the sleeve 120 polystyrene, even in case of deterioration thereof. The sheath 130 is advantageously formed of a sheath of heat-shrinkable polyethylene (PE).

Par ailleurs de préférence une housse externe 140 recouvre l'ensemble précité pour assurer sa protection à l'égard des chocs et aider à la visibilité. Cette housse peut être composée de tissu polyester enduit PVC. Pour assurer la visibilité, la housse 140 présente de préférence sur sa surface externe des bandes de couleurs contrastées ou alternées, avantageusement au moins partiellement réfléchissantes. A titre d'exemple non limitatif, à cette fin, la surface externe de couleur rouge de la housse 140 peut être recouverte d'une série (5 par exemple) de bandes blanches rétroréfléchissantes d'une largeur de 50mm réparties sur la longueur de la lisse.Furthermore, preferably an outer cover 140 covers the aforementioned assembly to ensure its protection against shocks and help visibility. This cover can be made of PVC coated polyester fabric.

By way of nonlimiting example, for this purpose, the outer surface of red color of the cover 140 may be covered with a series (5 for example) of retroreflective white strips of a width of 50 mm distributed over the length of the smooth.

De préférence la housse 140 est réalisée en deux parties pour permettre son remplacement aisé sans démonter la lisse.Preferably the cover 140 is made in two parts to allow its easy replacement without disassembling the arm.

By way of non-limiting example:
  • the tube 110 has an internal diameter of the order of 35 mm, an external diameter of the order of 38 mm and a length of the order of 3400 mm,
  • the inner diameter of the half-shells 122, 124 is substantially equal to the outer diameter of the tube 110 so that the half-shells 122, 124 closely match the outer surface of the tube 110,

La lisse de sécurité proposée dans le cadre de la présente invention offre de nombreux avantages par rapport aux moyens connus de l'état de la technique.The safety rail proposed in the context of the present invention offers many advantages over the known means of the state of the art.

Les inventeurs ont déterminé expérimentalement que l'utilisation d'une âme constituée d'un tube 110 en matériau composite permet de tolérer une déformation notable en cas d'impact sans entraîner ni détérioration de la lisse, ni effet néfaste important sur l'élément générant l'impact.The inventors have determined experimentally that the use of a core consisting of a tube 110 made of composite material makes it possible to tolerate a significant deformation in the event of an impact without causing the smoothing to deteriorate or have any significant adverse effect on the generating element. the impact.

Plus précisément la lisse précédemment décrite, qui possède un poids total de l'ordre de 2300g et un poids linéaire au mètre de l'ordre de 766g, présente une résistance aux impacts de véhicule jusqu'à 80km/h et ne génère pas de casse de pare-brise d'un véhicule jusqu'à 60km/h.More specifically, the previously described smooth, which has a total weight of the order of 2300 g and a linear weight per meter of the order of 766 g, has a resistance to vehicle impacts up to 80 km / h and does not generate breakage windshield of a vehicle up to 60km / h.

Par ailleurs la faible inertie de la lisse conforme à la présente invention, en raison de sa masse faible, combinée avec sa structure limitent fortement les risques de blesser ou d'assommer un piéton tentant de franchir le passage lors d'une manoeuvre de la barrière (on rappelle ici que la manoeuvre des barrières connues s'opèrent généralement en un temps inférieur à la seconde et que de nombreux accidents sont constatés auprès du personnel d'exploitation, des forces de l'ordre ou des usagers, avec les barrières antérieures connues).Moreover, the low inertia of the rail according to the present invention, because of its low mass, combined with its structure greatly limit the risk of hurting or stunning a pedestrian attempting to cross the passage during a maneuver of the barrier (It is recalled here that the maneuvering of the known barriers generally takes place in a time inferior to the second and that numerous accidents are noted with the operating personnel, the police force or the users, with the known previous barriers ).

L'utilisation d'une lisse ayant un diamètre extérieur important (typiquement de l'ordre de 100mm) permet d'en améliorer la visibilité et déjà en soi limite le risque d'impact, notamment par un piéton.The use of a rail having a large outside diameter (typically of the order of 100mm) makes it possible to improve its visibility and already in itself limits the risk of impact, in particular by a pedestrian.

L'utilisation d'une lisse présentant un poids linéaire inférieur à 800g/m permet d'augmenter la durée de vie des mécanismes d'entraînement par rapport aux dispositions de l'état de la technique.The use of a bar having a linear weight of less than 800 g / m makes it possible to increase the service life of the drive mechanisms compared to the provisions of the state of the art.

La présente invention peut toucher tous les domaines d'application des barrières levantes de sécurité, notamment mais non limitativement le domaine des péages automatiques autoroutiers et les péages de parking.The present invention may affect all the fields of application of safety barriers, including but not limited to the field of automated motorway tolls and parking tolls.

Comme on l'a évoqué précédemment, la lisse 100 est portée par un étrier 200 monté à rotation autour d'un axe horizontal 210 sur une borne 300.As mentioned above, the arm 100 is carried by a stirrup 200 rotatably mounted about a horizontal axis 210 on a terminal 300.

Plus précisément encore, comme on le voit sur les figures 3 et 4 annexées, l'extrémité de la lisse 100 adjacente à l'étrier 200 est engagée dans un manchon 220 lequel est lui même monté à rotation autour d'un axe vertical 222, grâce à des gonds 224 ou tous moyens équivalents, sur l'étrier 200. Par ailleurs la lisse 100 est supportée par l'étrier 200, à distance des gonds 224, par un système de pince 230. Celui-ci est de préférence formé de deux blocs élastiques 232, 234, en forme de sabots, disposés respectivement au dessous et au dessus de la lisse 100.More precisely, as we see on the Figures 3 and 4 annexed, the end of the arm 100 adjacent to the stirrup 200 is engaged in a sleeve 220 which is itself rotatably mounted about a vertical axis 222, by means of hinges 224 or any equivalent means, on the stirrup 200. Furthermore the smooth 100 is supported by the stirrup 200, to distance of the hinges 224, by a gripper system 230. This is preferably formed of two resilient blocks 232, 234, in the form of shoes, respectively disposed below and above the heald 100.

En fonctionnement normal, lorsque l'étrier 200 est entraîné à rotation autour de l'axe horizontal 210, la lisse 100 accompagne le mouvement de l'étrier 200, en étant maintenu sur celui-ci par la pince 230.In normal operation, when the stirrup 200 is rotated around the horizontal axis 210, the arm 100 accompanies the movement of the stirrup 200, being held thereon by the clamp 230.

En revanche lorsqu'un choc est appliqué sur la lisse 100, dans un premier temps, celle-ci peut se déformer grâce à l'élasticité intrinsèque du tube 110. Et si la force appliquée à la lisse 100, sous l'effet du choc, dépasse l'effort de serrage exercé par la pince 230, la lisse 100 peut sortir de la pince 230, en pivotant à l'horizontale, par rotation autour de l'axe vertical 222. Ainsi, la flexion de lisse est limitée et ne dépasse jamais la résistance globale à la flexion de celle-ci, ce qui augmente la durée de vie du dispositif.
Une fois l'élément appliquant le choc sur la lisse 100 retiré, la lisse peut être remise en place dans la pince. La barrière de sécurité est alors à nouveau fonctionnelle.On the other hand, when a shock is applied to the beam 100, initially, it can be deformed thanks to the intrinsic elasticity of the tube 110. And if the force applied to the arm 100, under the effect of the shock , exceeds the clamping force exerted by the clamp 230, the smooth 100 can out of the clamp 230, pivoting horizontally, by rotation about the vertical axis 222. Thus, the bending of the rail is limited and does not never exceeds the overall bending resistance of the latter, which increases the life of the device.
Once the element applying the shock on the arm 100 removed, the arm can be put back in place in the clamp. The security barrier is then functional again.

Bien entendu la présente invention n'est pas limitée aux modes de réalisation particuliers qui viennent d'être décrits, mais s'étend à toutes variantes conformes à son esprit.Naturally, the present invention is not limited to the particular embodiments which have just been described, but extends to all variants that are in keeping with its spirit.

En particulier l'homme de l'art pourra remplacer la pince 230 par tous moyens équivalents permettant de maintenir la lisse 100 solidaire de l'étrier 200 tant que l'effort d'impact appliqué sur la lisse 100 reste inférieur à un seuil, tout en autorisant un pivotement de la lisse 100 horizontalement par rapport à l'étrier 200 lorsque cet effort dépasse un seuil.In particular those skilled in the art can replace the clamp 230 by any equivalent means to maintain the smooth 100 integral with the yoke 200 as the impact force applied to the rail 100 remains below a threshold, while allowing a pivoting of the arm 100 horizontally relative to the bracket 200 when the force exceeds a threshold.
