Description
La présente invention concerne le domaine des barrières destinées à contrôler le passage sur une voie de circulation.The present invention relates to the field of 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 péages autoroutiers, les accès de parking, etc ...The barriers in accordance with the present invention may, 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 associée à un système d'entraînement adapté pour déplacer sélectivement la lisse entre une position de repos horizontale, transversale à la voie de circulation, propre à interdire le passage, et une position provisoire libérant ladite voie de circulation pour autoriser le passage par la voie de circulation, lorsqu'un accès autorisé est détecté.The known barriers generally comprise a rail associated with a drive system adapted to selectively move the rail between a horizontal rest position, transverse to the traffic lane, suitable for preventing the passage, and a temporary position releasing said lane for allow passage through the taxiway when authorized access is detected.
Bien qu'ayant rendu de grands services, les barrières connues ne donnent cependant pas toujours totalement satisfaction.Although having rendered great services, the known barriers do not always give complete satisfaction.
En particulier, l'un des problèmes mal résolu par les barrières existantes selon l'état de la technique, est celui de la remise en oeuvre rapide après un choc accidentel, par exemple lorsqu'un véhicule heurte la lisse d'une barrière de sécurité.In particular, one of the problems badly solved by the existing barriers according to the state of the art, is that of the rapid implementation after an accidental shock, for example when a vehicle hits the rail of a safety barrier .
Un grand nombre de barrières existantes conduisent, en cas de chocs importants, à la destruction pure et simple de la lisse, qu'il convient alors de remplacer. Ceci exige généralement un temps non négligeable.A large number of existing barriers lead, in case of major shocks, to the pure and simple destruction of the bar, which should then be replaced. This usually requires a significant amount of time.
Il a été proposé parfois de placer la lisse sur un équipage support associé au système d'entraînement de sorte que la lisse soit susceptible de déplacement par rapport à l'équipage support lorsqu'elle subit, en position de repos, un choc supérieur à un seuil pour éviter ainsi sa détérioration.It has sometimes been proposed to place the rail on a support unit associated with the drive system so that the rail is likely to move relative to the support crew when it undergoes, in the rest position, a shock greater than one. threshold to avoid deterioration.
Plus précisément, dans ce cas, lorsque le véhicule heurte la lisse d'une barrière de sécurité, un dispositif est prévu pour que la lisse sorte du parcours du véhicule en tournant autour d'un axe vertical lors de son déplacement relatif par rapport à l'équipage support. Ces barrières présentent cependant l'inconvénient d'obliger à une remise en place manuelle par le personnel, par exemple le péager, ce qui l'oblige à sortir de son local et à venir sur la voie de circulation, au risque d'être heurté par le véhicule suivant.More specifically, in this case, when the vehicle hits the rail of a safety barrier, a device is provided so that the rail exits the vehicle path by rotating about a vertical axis during its relative movement relative to the vehicle. crew support. These barriers have the disadvantage of requiring a manual reset by the staff, for example the public, which requires him to leave his local and come on the road, at the risk of being struck by the next vehicle.
Il a été proposé dans le document
Dans ce contexte l'objectif principal de l'invention est de proposer de nouveaux moyens permettant une remise en service rapide d'une lisse de barrière de sécurité après un choc accidentel.In this context, the main objective of the invention is to propose new means enabling a safety barrier bar to be put back into service rapidly after an accidental shock.

L'invention propose ainsi une lisse regondable automatiquement pour barrières de sécurité.The invention thus proposes a smoothly rewound automatically for safety barriers.
Selon une autre caractéristique avantageuse de la présente invention, la barrière de sécurité comprend en outre des moyens adaptés pour positionner automatiquement l'équipage mobile en position verticale lors d'une détection de dégondage de la lisse, par rapport à l'équipage support, de sorte que le regondage de celle-ci sur l'équipage support soit opéré en dehors de la voie de circulation.According to another advantageous characteristic of the present invention, the safety barrier further comprises means adapted to automatically position the moving equipment in a vertical position during a detachment detection of the rail, relative to the support crew, of so that the rerun of it on the support crew is operated outside the driving lane.
L'invention concerne également un ensemble autonome constitué de la combinaison de la lisse et de son équipage support, en tant que tel, hors de la connexion de cet ensemble sur le système d'entraînement.The invention also relates to an independent assembly consisting of the combination of the rail and its support crew, as such, outside the connection of this assembly on the drive system.

On va dans un premier temps faire un descriptif général de la barrière de sécurité conforme à la présente invention illustrée sur les figures annexées.We will initially make a general description of the safety barrier according to the present invention illustrated in the accompanying figures.
On a représenté sous la flèche référencée P le sens de passage du véhicule, sur les figures 1, 2 et 3.Shown under the arrow referenced P the direction of passage of the vehicle, in Figures 1, 2 and 3.

De préférence, l'équipage support 200 comprend un étrier 230 adapté pour être fixé sur l'arbre de sortie 310 des moyens d'entraînement, lequel pivote autour de l'axe horizontal principal 202. L'étrier 230 est de préférence en métal, par exemple en acier inoxydable. L'étrier 230 est formé d'une structure allongée de section droite en U. Il comprend une âme 232 pourvue, de part et d'autre, de deux ailes latérales 234, 236 perpendiculaires à l'âme 232.Preferably, the
L'âme 232 s'étend perpendiculairement à l'axe 202 principal de l'arbre de sortie 310 et est adaptée pour être fixée sur celui-ci. La lisse 100 est montée à rotation dans l'étrier 230 autour de l'axe secondaire 102 transversal à l'axe 202 de l'arbre de sortie 310 et perpendiculaire aux ailes latérales 234, 236.The
Pour cela, l'extrémité de la lisse 100 prend position, en position normale d'utilisation, dans le volume interne de l'étrier 230, entre les deux ailes latérales 234, 236.For this, the end of the
Plus précisément, de préférence, un support intermédiaire 130, par exemple en matériau thermoplastique, est engagé sur l'extrémité de la lisse 100 et placé dans l'étrier 230 pour servir de pièce d'articulation entre la lisse 100 et l'étrier 230, autour de l'axe 102, dans le cas où il y a éjection de la lisse 100. Le support intermédiaire 130 comprend de préférence deux coquilles ou flasques 131, 132 adaptées pour enserrer et pincer l'extrémité de la lisse 100 par serrage lorsqu'ils sont maintenus par des boulons 134 ou tout moyen équivalent.More specifically, preferably, an
Les inventeurs ont en effet déterminé qu'il est d'un grand intérêt de ne pas articuler directement la lisse 100 sur l'étrier 200. De fait, articuler la lisse 100 sur l'étrier 230 via un support intermédiaire 130, permet un remplacement facile et rapide de la lisse 100 si nécessaire. Il suffit en effet alors de desserrer les boulons 134 maintenant les deux flasques 131, 132, de retirer la lisse 100 par traction selon son axe longitudinal, de la remplacer et de resserrer les boulons 134.The inventors have in fact determined that it is of great interest not to directly articulate the
Les moyens élastiques 220 adaptés pour assurer le regondage automatique de la lisse 100 sur l'équipage support 200 sont formés de préférence de deux ressorts 222, 224, de torsion, coaxiaux entre eux et coaxiaux de l'axe secondaire 102, montés respectivement de part et d'autre de l'étrier 230, sur une entretoise respective cylindrique 232, 234. Comme on le voit notamment sur la figure 2, de préférence chaque entretoise 232, 234 possède une tête élargie 233, 235, à son extrémité, assurant le maintien du ressort respectif 222, 224.The elastic means 220 adapted to ensure the automatic rerouting of the
Les entretoises 232, 234 sont elles-mêmes centrées sur l'axe secondaire 102. Elles sont réalisées de préférence en matériau thermoplastique.The
Une extrémité 2220, 2240 de chaque ressort 222, 224, est liée à une patte 240 solidaire de l'étrier 230, plus précisément de son âme 232. La patte 240 s'étend globalement parallèlement à l'axe secondaire 102.One
Une seconde extrémité 2222, 2242 de chaque ressort 222, 224 est liée au support intermédiaire 130, de préférence respectivement à l'un des flasques 131, 132, et avantageusement à distance de l'axe secondaire 102 pour appliquer un couple de rappel suffisant sur l'équipage intermédiaire 130 et la lisse 100 qui y est liée.A
Comme indiqué précédemment, les ressorts 222, 224 ont pour but d'assurer le regondage automatique de la lisse 100 sur l'équipage support 200 dans le cas où celle-ci est éjectée par pivotement autour de l'axe secondaire 102, par un véhicule. Le regondage de la lisse 100 sur l'étrier 230 est assuré quelle que soit la position de la lisse, horizontale ou verticale, et son angle de dégondage, de 0 à 90°. A titre d'exemple non limitatif, les ressorts 222, 224 sont réalisés en acier inoxydable Z10CN18.08 écroui et d'une capacité de l'ordre de 57Nm à 60°C.As indicated above, the
Selon le mode de réalisation particulier représenté sur les figures annexées (mais comme indiqué précédemment la disposition inverse peut être retenue), le support intermédiaire 130 porte une plaque 110 formant pièce polaire placée en regard d'un aimant 210 porté par l'âme 232 de l'étrier 230. Ces moyens 110, 210 assurent un maintien de la lisse 100 en position dans l'étrier 200 tant qu'un effort dépassant un seuil n'est pas appliqué sur la lisse 100 pour tendre à pivoter celle-ci autour de l'axe secondaire 102.According to the particular embodiment shown in the accompanying figures (but as indicated above, the reverse arrangement can be retained), the
Par ailleurs, de préférence, l'aimant 210 et/ou la plaque polaire 110 sont portés par leur support respectif avec un certain degré de liberté de déplacement pour garantir un parfait contact entre les faces en regard de la plaque polaire 110 et de l'aimant 210, en position de repos de la barrière de sécurité. Cette disposition permet de s'affranchir de tout risque de défaut de parallélisme entre les faces en regard de ces éléments. A titre d'exemple non limitatif à cette fin, l'aimant 210 peut être porté par l'âme 232 de l'étrier 230 par l'intermédiaire d'une rondelle en caoutchouc amortisseur 212. Une telle rondelle 212 permet de donner de la souplesse d'orientation à l'aimant 210. Lors d'une percussion de la lisse 100, la plaque polaire 110 se décolle et permet à la lisse d'être éjectée en pivotant autour de l'axe secondaire 102. A titre d'exemple non limitatif, la force de maintien de l'aimant 210 peut être de l'ordre 160daN.Furthermore, preferably, the
En variante, l'aimant 210 peut être remplacé par un électro-aimant sous réserve de veiller à assurer l'alimentation de celui-ci électriquement.Alternatively, the
Comme on le voit sur la figure 1 annexée, de préférence, la barrière de sécurité conforme à la présente invention comprend en outre un capot de protection 250 fixé sur le support intermédiaire 130, pour suivre les mouvements de celui-ci. Le capot 250 a pour but de protéger le système et d'assurer un certain esthétisme à l'ensemble. Il peut faire l'objet de nombreuses variantes de réalisation et ne sera donc pas décrit dans le détail par la suite.As seen in Figure 1 attached, preferably, the safety barrier according to the present invention further comprises a
De préférence, la barrière de sécurité conforme à la présente invention comporte par ailleurs, des moyens adaptés pour détecter le dégondage de la lisse 100 par rapport à l'étrier 230, c'est-à-dire le pivotement de la lisse 100 par rapport à l'étrier 230, autour de l'axe secondaire 102, en dehors de sa position normale d'utitisation. Il est également de préférence prévu des moyens adaptés pour positionner automatiquement l'équipage mobile 200 en position verticale, telle qu'illustrée sur la figure 3 lors d'une telle détection de dégondage de la lisse 100 de sorte que le regondage de celle-ci sur l'équipage support 200 sous l'effet de la sollicitation exercée par les ressorts 222, 224, soit opérée en dehors de la voie de circulation.Preferably, the safety barrier according to the present invention further comprises means adapted to detect the disengagement of the
Les moyens de détection précités peuvent faire l'objet de nombreux modes de réalisation. Ils sont formés de préférence d'un capteur inductif 260 porté par l'âme 232 de l'étrier 230 en regard d'un index métallique complémentaire 160 porté par le support intermédiaire 130.The aforementioned detection means can be the subject of many embodiments. They are preferably formed of an
Un tel capteur 260 détecte la présence de la lisse 100 en position normale. Le capteur 260 transmet l'information de dégondage de la lisse 100, en cas de choc, et dans ce cas donne un ordre d'ouverture de la barrière pour positionner l'équipage mobile 200 en position verticale telle qu'illustrée sur la figure 3. Il déclenche également une temporisation de la fermeture de la lisse, afin de permettre au ressort 222, 224 de garantir le regondage de celle-ci en position ouverte, hors voie de passage, avant d'autoriser la fermeture de la barrière.Such a
Le fonctionnement de la barrière de sécurité conforme à la présente invention est essentiellement le suivant.The operation of the safety barrier according to the present invention is essentially as follows.
Lorsqu'un dégondage de la lisse 100 a été effectué suite à un choc sur la lisse, le capteur de présence de lisse 260 donne l'ordre à la carte électronique de gestion présente dans la borne 300 et pilotant le moyen d'entraînement, d'effectuer une remontée de l'équipage mobile 200 en position verticale telle qu'illustrée sur la figure 3. Cette remontée peut être temporisée ou non. Pendant la remontée de l'équipage mobile 200, si la lisse 100 n'est pas contrariée par la présence d'un obstacle, les deux ressorts 222, 224 assurent le regondage de la lisse sur l'étrier 230 dans la position initiale de fonctionnement. La lisse 100 étant revenue dans sa position, le capteur 260 peut donner l'ordre au système de reprendre son cycle normal.When a stripping of the
Le maintien de la lisse 100 sur l'étrier 230 est alors assuré par l'aimant 210 qui évite tout mouvement intempestif non commandé de la lisse 100.Maintaining the
Par rapport à la technique antérieure, la barrière de sécurité conforme à la présente invention offre de nombreux avantages. Le dispositif conforme à la présente invention permet une remise en place automatique de la lisse de la barrière, en cas d'éjection de celle-ci, qui ne nécessite plus d'intervention humaine. Ceci évite au personnel d'aller sur la voie de circulation et diminue grandement le risque d'accident, notamment aux barrières de péage.Compared to the prior art, the safety barrier according to the present invention offers many advantages. The device according to the present invention allows automatic replacement of the barrier bar, in case of ejection thereof, which no longer requires human intervention. This prevents staff from going on the taxiway and greatly reduces the risk of accidents, especially at the toll gates.
Le système conforme à la présente invention est adaptable sur tout type de barrière. Il suffit en effet de le fixer sur l'arbre de rotation 310 des barrières existantes.The system according to the present invention is adaptable to any type of barrier. It suffices to fix it on the
De préférence, la lisse 100 est réalisée en matériau composite tel que défini dans la demande de brevet n°
Le dégondage et le regondage s'effectuent sur un angle pouvant atteindre 90°. Le regondage s'effectue pendant que la lisse 100 est en position dégagée sur le côté de la voie. Il ne perturbe aucunement la circulation.Dismantling and rerouting take place at an angle of up to 90 °. Rooting is performed while the
On notera par ailleurs que les moyens conformes à la présente invention présentent une parfaite symétrie par rapport à leur axe longitudinal. Ainsi un modèle unique suffit pour une installation de lisse à droite ou à gauche.Note also that the means according to the present invention have a perfect symmetry with respect to their longitudinal axis. Thus a single model is sufficient for a smooth installation on the right or on the left.
Bien entendu la présente invention n'est pas limitée au mode de réalisation particulier qui vient d'être décrit mais s'étend à toute variante conforme à son esprit.Of course, the present invention is not limited to the particular embodiment which has just been described but extends to any variant within its spirit.
Le cas échéant, le support intermédiaire 130 et l'étrier 230 peuvent être pourvus de moyens, typiquement des alésages 190, 290 propres à recevoir un boulon ou une goupille ou tout moyen équivalent adapté pour maintenir le support intermédiaire 130 et par conséquent la lisse 100 sur l'équipage mobile 200 pour interdire, si l'exploitant le souhaite, tout dégondage de la lisse 100 par rapport à l'étrier 230.If necessary, the
De préférence dans le cadre de la présente invention, il est par ailleurs prévu des moyens limitant le débattement autorisé entre la lisse 100 et l'équipage support 200 à un angle de l'ordre de 90°.Preferably in the context of the present invention, there is further provided means limiting the clearance allowed between the
Selon le mode de réalisation représenté sur les figures annexées, ces moyens limitant le débattement de la lisse sont formés par l'extrémité du support intermédiaire 130 susceptible de venir en butée contre une arête 233 de l'âme 232 de l'étrier 230.According to the embodiment shown in the accompanying figures, these means limiting the deflection of the arm are formed by the end of the
A cette fin, l'âme 232 de l'étrier possède une longueur inférieure à celle des ailes latérales 234, 236. Par ailleurs, le support intermédiaire 130 s'étend, sur son extrémité, au-delà de l'axe secondaire 102 sur une longueur supérieure à son épaisseur considérée transversalement à cet axe secondaire 102.To this end, the
On notera par ailleurs sur les figures annexées, que la hauteur du support intermédiaire 130 considéré parallèlement à l'axe secondaire 102 est égale à la distance séparant les deux ailes latérales 232, 234 pour éviter tout jeu intempestif entre la lisse 100 et l'étrier 230 en position normale d'utilisation.It will also be noted in the appended figures, that the height of the
Selon une autre caractéristique avantageuse de la présente invention, la barrière comprend des moyens de support souple de l'un des moyens de maintien pour permettre un auto positionnement de celui-ci.According to another advantageous characteristic of the present invention, the barrier comprises flexible support means of one of the holding means to allow self-positioning thereof.
Selon une autre caractéristique avantageuse de la présente invention, la barrière comprend des moyens qui interdisent un positionnement de l'équipage mobile en position horizontale tant que la lisse n'est pas regondée sur l'équipage mobile.According to another advantageous characteristic of the present invention, the barrier comprises means which prohibit positioning of the moving element in a horizontal position as long as the rail is not raised on the moving equipment.
