La présente invention concerne un dispositif support notamment pour un bras mobile de signalisation routière et particulièrement applicable à la signalisation routière d'urgence et ou de modification de parcours.The present invention relates to a support device in particular for a mobile signaling road arm and particularly applicable to emergency road signs and or modification of course.

Des bras mobiles de signalisation et d'interdiction de passage sont connus et notamment le document US 4 811 516 concerne un bras, mobile dans un plan vertical autour d'un axe horizontal.Mobile signaling arms and prohibition of passage are known and in particular the document US 4,811,516 relates to an arm movable in a vertical plane about a horizontal axis.

Un tel bras peut être pourvu d'un contre poids qui compense le poids du bras, les efforts sur l'axe étant ainsi équilibrés et seul les effets du vent doivent être compensés.Such an arm can be provided with a counterweight which compensates for the weight of the arm, the forces on the axis being thus balanced and only the effects of the wind must be compensated.

Un tel bras nécessite toutefois un support laissant libre une section de passage suffisante dans un plan vertical pour le bras.Such an arm however requires a support leaving free a sufficient passage section in a vertical plane for the arm.

Dans le cas d'une implantation de barrières mobiles sur des sections d'autoroute comportant des glissières de protection ou des organes de sécurité tels que des glissières béton armé, il est impossible de dégager un espace de passage pour le bras ou le contrepoids dans le rail ou la glissière.In the case of the installation of movable barriers on motorway sections with guard rails or safety devices such as reinforced concrete slides, it is impossible to clear a passage space for the arm or the counterweight in the rail or slide.

En outre, les barrières mobiles doivent être positionnées à une hauteur de l'ordre de 40 centimètres du sol ce qui pose un problème de positionnement de leurs axes du fait que les glissières sont généralement de hauteur largement supérieure à 40 cm.In addition, the movable barriers must be positioned at a height of about 40 centimeters from the ground, which poses a problem of positioning their axes because the slides are generally of a height much greater than 40 cm.

La présente invention résout ce problème en proposant un dispositif support, notamment pour un élément de bras mobile, agencé pour se plaquer contre la face avant du rail ou de la glissière et pour permettre à l'élément de bras de pivoter autour d'un axe se trouvant en retrait de la face avant de la glissière ou du rail dans un plan horizontal entre une première position pour restreindre la voie ou interdire le passage et une seconde position pour laquelle le bras est plaqué contre la face avant du rail ou de la glissière.The present invention solves this problem by providing a support device, in particular for a movable arm element, arranged to press against the front face of the rail or slide and to allow the arm member to pivot about an axis. recessed from the front face of the rail or rail in a horizontal plane between a first position to restrict the track or prohibit the passage and a second position for which the arm is pressed against the front face of the rail or slide.

La glissière est notamment une glissière béton et le bras se déplace en particulier dans un plan horizontal situé sous le sommet de la glissière.The slide is in particular a concrete slide and the arm moves in particular in a horizontal plane located under the top of the slide.

En outre, le support selon l'invention permet, malgré le porte à faux que cause la distance et la différence de hauteur entre l'axe positionné sur la glissière ou même derrière la glissière et le bras, positionné en avant de la glissière, au dispositif de signalisation comportant le support et le bras, de résister à des coups de vent importants voir supérieurs à 90km/h.In addition, the support according to the invention allows, despite the overhang that causes the distance and the difference in height between the axis positioned on the slide or even behind the slide and the arm, positioned in front of the slide, to signaling device comprising the support and the arm, to withstand large gusts of wind or over 90km / h.

Pour ce faire, la présente invention concerne principalement un dispositif de support rotatif d'un élément de bras, mobile entre une première position et une seconde position, comportant un dispositif de manoeuvre de l'élément de bras et un support du dispositif de manoeuvre caractérisé en ce que le support du dispositif de manoeuvre comporte un axe vertical recevant un organe de liaison, l'organe de liaison étant pourvu d'une tête d'emmanchement sur l'axe, étant pourvu en outre d'un segment d'arche descendant muni d'une jambe de raccordement à l'élément de bras et étant conformé pour maintenir l'élément de bras entre lesdites première et seconde positions, l'axe vertical et l'élément de bras étant décalés dans un plan vertical et éloignés dans un plan horizontal.To do this, the present invention mainly relates to a device for rotating support of an arm member, movable between a first position and a second position, comprising a device for operating the arm member and a support of the operating device characterized in that the support of the operating device comprises a vertical axis receiving a connecting member, the connecting member being provided with a fitting head on the axis, being further provided with a descending arch segment. provided with a connecting leg to the arm member and being shaped to hold the arm member between said first and second positions, the vertical axis and the arm member being offset in a vertical plane and spaced apart in a horizontal plane.

Plus particulièrement et pour renforcer le dispositif, le segment d'arche de l'organe de liaison est constitué en caisson en forme de segment hélicoïdal répartissant les efforts occasionnés par l'élément de bras au long du segment d'arche.More particularly and to reinforce the device, the arch segment of the connecting member is constituted by a box-shaped helical segment distributing the forces caused by the arm member along the arch segment.

En mode de réalisation particulier, l'axe est un axe fixe solidaire du support de réception du dispositif de manoeuvre et la tête d'emmanchement peut notamment être pourvue d'une couronne inférieure solidaire d'une première extrémité d'un organe de manoeuvre dont la seconde extrémité est solidaire d'un moteur d'entraînement de l'élément de bras en rotation entre la première position et la seconde position.In particular embodiment, the axis is a fixed axis secured to the receiving support of the operating device and the fitting head may in particular be provided with a lower ring secured to a first end of a maneuver member whose the second end is integral with a driving motor of the arm element rotating between the first position and the second position.

L'exemple de réalisation représenté notamment en figures 1 et 2 concerne un dispositif de signalisation à bras mobile utilisant un dispositif support selon l'invention. Le dispositif de signalisation représenté est réalisé dans l'optique d'une grande simplicité de fabrication et de mise en oeuvre du dispositif de signalisation. Pour ce faire, le dispositif de signalisation selon l'invention comporte un élément de bras 1, mobile entre une position de liberté de passage et une position d'interdiction de passage, un dispositif de manoeuvre 2 du bras et un support 3 du dispositif de manoeuvre adapté pour se fixer sur une glissière 10 longeant une chaussée.The embodiment shown in particular in Figures 1 and 2 relates to a mobile arm signaling device using a support device according to the invention. The signaling device shown is made in view of a great simplicity of manufacture and implementation of the signaling device. To do this, the signaling device according to the invention comprises an arm member 1, movable between a position of freedom of passage and a no-go position, a maneuvering device 2 of the arm and a support 3 of the device. maneuver adapted to attach to a slide along a roadway.

L'élément de bras 1 peut être une partie d'une barrière de sécurité, un support d'un panneau ou d'une lampe de signalisation ou autre dispositif de signalisation.The arm member 1 may be a part of a safety barrier, a support of a sign or signal lamp or other signaling device.

Le dispositif de support rotatif de l'élément de bras 1, mobile entre une première position, la position de liberté de passage, et une seconde position, la position d'interdiction de passage, comporte un dispositif de manoeuvre 2 du bras et un support 3 du dispositif de manoeuvre.The rotary support device of the arm element 1, movable between a first position, the position of freedom of passage, and a second position, the non-passage position, comprises a device 2 for maneuvering the arm and a support 3 of the maneuvering device.

Le support 3 du dispositif de manoeuvre comporte un axe vertical 4 recevant un organe de liaison 5, l'organe de liaison 5 étant pourvu en premier lieu d'une tête 6 d'emmanchement sur l'axe 4 et en second lieu d'un segment d'arche descendant 7 muni d'une jambe 8 de raccordement à un élément du bras 1. En outre, l'organe de liaison est conformé en sorte de maintenir le bras entre lesdites première et seconde positions, l'axe vertical et le bras étant décalés dans un plan vertical et éloignés dans un plan horizontal.The support 3 of the operating device comprises a vertical axis 4 receiving a connecting member 5, the connecting member 5 being provided in the first place with a head 6 of fitting on the axis 4 and secondly with a descending arch segment 7 provided with a leg 8 connecting to an element of the arm 1. In addition, the connecting member is shaped so as to maintain the arm between said first and second positions, the vertical axis and the arms being offset in a vertical plane and distant in a horizontal plane.

L'axe vertical 4 du dispositif de manoeuvre permet la rotation du bras dans un plan horizontal entre la position de liberté de passage, représentée en figure 1, pour laquelle le bras longe la glissière, et, la position d'interdiction de passage, représentée en figure 2, pour laquelle le bras s'étend au travers de la chaussée.The vertical axis 4 of the maneuvering device enables the arm to be rotated in a horizontal plane between the position of freedom of passage, represented in FIG. 1, for which the arm runs along the slide, and the non-passage position, shown in Figure 2, for which the arm extends through the roadway.

Selon l'exemple représenté en figure 3, cet axe vertical reçoit un organe de liaison 5 pourvu d'une tête 6 d'emmanchement sur l'axe et pourvu en outre d'un segment d'arche descendant 7 muni d'une jambe 8 de raccordement au bras 1 et conformé pour maintenir le bras parallèle à la glissière en position de liberté de passage et pour maintenir le bras écarté de la glissière et même en position perpendiculaire à la glissière en position d'interdiction de passage.According to the example shown in FIG. 3, this vertical axis receives a connecting member 5 provided with a head 6 fitting on the axis and further provided with a descending arch segment 7 provided with a leg 8 connection to the arm 1 and shaped to keep the arm parallel to the slide in the free passage position and to keep the arm away from the slide and even in a position perpendicular to the slide in the closed position.

Le dispositif de signalisation réalisé est conçu en sorte de ne pas occasionner de blessures aux passagers de véhicules le percutant en cas d'accident à des vitesses importantes pour des raisons de sécurité.The signaling device produced is designed so as not to cause injury to passengers of vehicles hitting it in case of accident at high speeds for safety reasons.

Dans cette optique, le matériau constituant le bras doit, en cas d'impact d'un véhicule, ne pas risquer d'occasionner de blessures aux occupants de ce véhicule et, pour ce faire, un matériau composite se délaminant en cas de choc accidentel d'un véhicule sera préféré.In this context, the material constituting the arm must, in the event of impact of a vehicle, not risk risking injury to the occupants of this vehicle and, to do this, a composite material delaminating in case of accidental shock a vehicle will be preferred.

En outre, le dispositif de signalisation doit être d'une construction robuste et légère tout en conservant une importante résistance au vent.In addition, the signaling device must be of a robust and lightweight construction while maintaining a high wind resistance.

Dans ce but, l'organe de liaison est conformé pour autoriser le débattement du bras à proximité de la barrière et profilé pour offrir peu de prise au vent, que ce soit dans la position de liberté de passage ou dans la position d'interdiction de passage et notamment, le segment d'arche 7 de l'organe de liaison 5 est constitué en caisson avec une partie supérieure 9a pourvue d'un plafond et de faces latérales, et d'une partie inférieure 9b, ce caisson pouvant être réalisé dans un matériau composite constitué d'une résine et de tissu de verre, le caisson étant éventuellement ensuite rempli à différents endroits d'une mousse telle qu'une mousse alvéolaire ou construit autour d'une structure nid d'abeille pour en accroître la rigidité.For this purpose, the connecting member is shaped to allow the movement of the arm close to the barrier and profiled to offer little grip wind, whether in the position of freedom of passage or in the position of prohibition of passage and in particular, the arch segment 7 of the connecting member 5 is constituted box with an upper portion 9a provided with a ceiling and side faces, and a lower part 9b, this box can be made in a composite material consisting of a resin and glass fabric, the box being optionally subsequently filled at different places with a foam such as foam or built around a honeycomb structure to increase the rigidity.

Pour optimiser les caractéristiques mécaniques de l'organe de liaison tout en autorisant un débattement important au bras, le segment d'arche 7 de l'organe de liaison 5 est réalisé en forme de segment hélicoïdal qui permet de répartir les efforts du bras au long du segment d'arche 7.To optimize the mechanical characteristics of the connecting member while allowing a large clearance to the arm, the arch segment 7 of the connecting member 5 is in the form of a helical segment that distributes the forces of the arm along of the arch segment 7.

En outre et préférablement, au moins le segment d'arche du dispositif support est réalisé en caisson refermé sur sa face inférieure.In addition and preferably, at least the arch segment of the support device is made of box closed on its underside.

Cette conformation en segment hélicoïdal a pour avantage de déporter du poids du côté de la glissière et de répartir les efforts par rapport à l'axe de rotation du bras.This helical segment conformation has the advantage of deporting the weight of the side of the slide and distribute the forces relative to the axis of rotation of the arm.

Le dispositif comporte un dispositif manuel de blocage du bras dans la première position et ou dans la seconde position et notamment, selon l'exemple d'application, en position de liberté de passage et en position d'interdiction de passage. Le dispositif de blocage selon l'exemple comporte des trous d'indexage 21, 22 dans lesquels se positionnent un moyen de blocage tel qu'une goupille connue en soi.The device comprises a manual device for locking the arm in the first position and or in the second position and in particular, according to the application example, in the position of freedom of passage and in the no-go position. The locking device according to the example comprises indexing holes 21, 22 in which are positioned a locking means such as a pin known per se.

Comme représenté en figure 3, la tête 6 d'emmanchement de l'organe de liaison sur l'axe 4 comporte une partie semi-tubulaire recevant l'axe. De façon à permettre une rotation aisée de la tête sur l'axe, une chemise 11 de réception de l'axe 4 est emmanchée sur la tête. Cette chemise est pourvue d'une paroi interne épousant le profil externe de l'axe et autorisant une rotation avec le moins de jeu possible de la chemise sur l'axe.As shown in Figure 3, the head 6 of fitting of the connecting member on the axis 4 comprises a semi-tubular portion receiving the axis. In order to allow easy rotation of the head on the axis, a sleeve 11 receiving the axis 4 is fitted on the head. This jacket is provided with an inner wall matching the outer profile of the axis and allowing rotation with the least possible play of the liner on the axis.

Selon la figure 4, pour permettre une grande rigidité de l'ensemble bras/organe de liaison sur l'axe de rotation, le dispositif est réalisé de sorte que l'axe 4 soit un axe fixe solidaire du support 3 de réception du dispositif de manoeuvre.According to FIG. 4, to allow a great rigidity of the arm / linker assembly on the axis of rotation, the device is made so that the axis 4 is a fixed axis integral with the support 3 for receiving the device. maneuver.

Dans ce cadre, la tête d'emmanchement 6 est donc mobile autour de l'axe et un dispositif de manoeuvre est relié à la tête d'emmanchement pour permettre sa rotation autour de l'axe fixe.In this context, the fitting head 6 is thus movable about the axis and an operating device is connected to the fitting head to allow its rotation about the fixed axis.

En particulier, la tête d'emmanchement est pourvue d'une couronne supérieure 12 solidaire d'une première extrémité 13 d'un organe de manoeuvre 14 dont la seconde extrémité 15 est solidaire d'un moteur 16 d'entraînement du bras en rotation entre la position de liberté de passage et la position d'interdiction de passage.In particular, the fitting head is provided with an upper ring 12 secured to a first end 13 of an operating member 14 whose second end 15 is integral with a motor 16 driving the arm in rotation between the position of freedom of passage and the position of prohibition of passage.

L'organe de manoeuvre peut être constituée d'un dispositif télescopique à vis, le moteur 16 faisant tourner un manchon externe 14a à filetage interne recevant une tige filetée 14b, la rotation du manchon 14a dans un premier sens faisant sortir la tige 14b et, dans le sens opposé, la faisant rentrer dans le manchon, l'organe de manoeuvre agissant dans ce cas comme réducteur pour permettre d'utiliser un moteur de puissance réduite pour commander le déplacement du bras.The operating member may consist of a telescopic screw device, the motor 16 rotating an outer sleeve 14a with internal thread receiving a threaded rod 14b, the rotation of the sleeve 14a in a first direction out of the rod 14b and, in the opposite direction, making it enter the sleeve, the actuator acting in this case as a reducer to allow the use of a reduced power motor to control the movement of the arm.

Toujours selon la figure 4, le support 3 comporte un socle supportant l'axe 4 et un bras de liaison 17 avec le moteur, la longueur du bras de liaison étant adaptée pour permettre le complet déploiement du bras entre les position d'interdiction de passage et de liberté de passage en fonction de la position d'accrochage de l'extrémité de la tige 14 sur une zone périphérique de la couronne supérieure, du débattement de l'organe de manoeuvre et du taux de réduction choisi.Still according to Figure 4, the support 3 comprises a base supporting the axis 4 and a connecting arm 17 with the motor, the length of the connecting arm being adapted to allow the full deployment of the arm between the no-go position and freedom of passage depending on the attachment position of the end of the rod 14 on a peripheral zone of the upper ring, the travel of the operating member and the chosen reduction ratio.

Pour permettre l'arrêt du moteur, le dispositif comporte au moins un capteur 18, 19 de position de fin de course en regard d'un élément mobile solidaire de l'organe de liaison et, dans le cas particulier de l'exemple représenté pour lequel la couronne supérieure 12 repose sous un disque 20 assujetti au support et sous lequel se trouve la couronne inférieure fixe 23, le dispositif comporte deux capteurs fin de course 18, 19, solidaires de la couronne inférieure fixe 23 et disposés, en regard d'un élément de la couronne supérieure 12 aux extrémités d'un secteur angulaire (S) correspondant au déplacement de l'élément de bras 1 de la position de liberté de passage à la position d'interdiction de passage.To allow the motor to stop, the device comprises at least one end position sensor 18, 19 facing a movable element integral with the connecting member and, in the particular case of the example shown for which the upper ring 12 rests under a disk 20 secured to the support and under which is the fixed lower ring gear 23, the device comprises two end-of-travel sensors 18, 19 integral with the fixed lower ring gear 23 and arranged, opposite an element of the upper ring 12 at the ends of an angular sector (S) corresponding to the displacement of the arm member 1 from the position of freedom of passage to the no-pass position.

Enfin, comme décrit notamment en figure 1, la tête d'emmanchement est pourvue d'une jupe prolongeant le disque 20 et masquant tout ou partie du dispositif de manoeuvre et le protégeant des intempéries.Finally, as described in particular in Figure 1, the fitting head is provided with a skirt extending the disc 20 and masking all or part of the operating device and protecting the weather.

Le support 3 du dispositif de manoeuvre se fixe sur la glissière 10 au travers de moyens de fixation tels que des boulons ou des tiges pénétrant dans la glissière 10. Selon un mode de réalisation particulier de l'invention, les moyens de fixation du support sont des moyens fusibles 24 adaptés à désolidariser le support de la glissière en cas de choc violent, et donc à désolidariser le dispositif de la barrière en cas de choc violent d'un objet contre le dispositif support et/ou la barrière afin d'éviter des dommages aggravés à une personne éjectée d'un véhicule tel qu'une motocyclette et qui viendrait heurter le dispositif.The support 3 of the operating device is fixed on the slide 10 through fastening means such as bolts or rods penetrating into the slide 10. According to a particular embodiment of the invention, the means for fixing the support are fusible means 24 adapted to separate the support of the slideway in the event of a violent impact, and thus to separate the device from the barrier in the event of violent impact of an object against the support device and / or the barrier in order to avoid aggravated damage to a person ejected from a vehicle such as a motorcycle and who would hit the device.

Dans ce cadre, les moyens fusibles peuvent être par exemple calibrés pour se rompre lorsqu'un objet d'une masse donnée rencontre le dispositif à une vitesse donnée.In this context, the fusible means may for example be calibrated to break when an object of a given mass meets the device at a given speed.

A titre d'exemple, les moyens fusibles peuvent être calibrés pour se rompre si un objet d'une masse supérieure à 20 Kg projeté à une vitesse de plus de 60 km/H rencontre le dispositif support.By way of example, the fusible means may be calibrated to break if an object of a mass greater than 20 Kg projected at a speed of more than 60 km / h encounters the support device.

L'invention ne se limite pas à l'exemple représenté et notamment le dispositif support et le bras de liaison permettant un déport tant vertical qu'horizontal d'un élément se déplaçant en rotation par rapport à un élément de support sont utilisables pour d'autres applications que des bras barrières.The invention is not limited to the example shown and in particular the support device and the connecting arm allowing both vertical and horizontal offset of an element moving in rotation with respect to a support element can be used for other applications than barrier arms.

De même, d'autre configuration d'entraînement entre le moteur et la couronne de commande de rotation du bras est possible tout en restant dans le cadre de l'invention.Likewise, other drive configuration between the motor and the rotation control ring of the arm is possible while remaining within the scope of the invention.
