Description

Dispositif mobile pour signaler l'occupation d'une voie routière et dévoyer la circulation. Mobile device for signaling the occupation of a road lane and diverting traffic.
La présente invention concerne le domaine routier et plus particulièrement & chaussée séparée et a pour objet un dispositif de signalisation mobile pour informer le plus en amont possible les usagers d'une route de l'occupation d'une voie et pour dévoyer la circulation.The present invention relates to the road sector and more particularly to a separate roadway and has as its object a mobile signaling device to inform road users as far upstream as possible of the occupation of a lane and to divert traffic.
En France, en particulier, la signalisation de la neutralisation d'une voie est traditionnellement faite manuellement avec une vingtaine de panneaux de 1'ordre du mètre carré de surface mis en place sur la voie sous circulation ce gui est doublement gênant pour les automobilistes, long et excessivement dangereux tant & la pose qu'à la dépose pour les usagers et les agents gui en viennent à refuser d'exécuter ces travaux. A l'étranger, des systèmes mobiles sont utilisés composés d'un camion et d'une remorgue spéciale portant un panneau escamotable important pourvu d'une flèche matérialisée par une dizaine de spots de l'ordre de trente centimètres de diamètre.In France, in particular, signaling for the neutralization of a lane is traditionally done manually with around twenty panels of the order of a square meter of surface installed on the lane under traffic, this mistletoe is doubly annoying for motorists, long and excessively dangerous both for installation and for removal for users and agents who come to refuse to perform this work. Abroad, mobile systems are used composed of a truck and a special trailer carrying a large retractable panel provided with an arrow materialized by a dozen spots of the order of thirty centimeters in diameter.
Ce deuxième système est plus efficace, néanmoins l'ensemble camion remorque eβt lourd, encombrant, et les manoeuvres d'installation et de repli sont délicates, de plus la visibilité peut être altérée par la présence de poids lourds, l'impact de l'information n'est pas aussi performant qu'il serait souhaitable, et en cas de heurt les conséquence-- peuvent être désastreuses . Le dispositif selon l'invention permet de remédier à ces inconvénients. D'une part, il est monté prêfêrentiellement en kit sur un véhicule de 2 à 5 tonnes de poids -total en charge, voire sur une remorque, et permet de signaler la neutralisation d'une voie sur une route à chaussées séparées et à amener l'usager i ralentir progressivement d'abord et à se dévoyer ensuite.This second system is more efficient, however the heavy and bulky eβt trailer truck assembly, and the installation and fall-back maneuvers are delicate, moreover visibility can be impaired by the presence of heavy goods vehicles, the impact of information is not as effective as it would be desirable, and in the event of an impact the consequences - can be disastrous. The device according to the invention overcomes these drawbacks. On the one hand, it is preferably mounted as a kit on a vehicle of 2 to 5 tonnes of total weight laden, or even on a trailer, and makes it possible to signal the neutralization of a lane on a road with separate carriageways and to be brought the user i gradually slow down first and then deviate.
D'autre part, il permet de minimiser considérablement les suites d'un tamponnage arrière ou latéral en protégeant les matériels et les hommes des véhicules tamponneurs et tamponnés.On the other hand, it makes it possible to considerably minimize the consequences of rear or lateral buffering by protecting the equipment and the men of the bumper and buffered vehicles.
Le dispositif comporte un bras motorisé, articulé à l'une de ses extrémités muni à l'autre extrémité d'un réflecteur prêfêrentiellement parabolique équipé d'une source lumineuse prêfêrentiellement halogène, coiffés d'un cache extérieur délimitant prêfêrentiellement une flèche, l'ensemble pouvant être vu à une distance de l'ordre du kilomètre, le bras, en fonction est en permanence animé d'un mouvement de rotation alternatif orienté soit du côté droit pour dévoyer à droite, soit du côté gauche pour dévoyer à gauche, en même temps qu'est éclairée la source lumineuse, soit en continu, soit en discontinu, pendant la descente du bras prêfêrentiellement à allumage et extinction progressifs. Le triple cumul ci-après définiThe device comprises a motorized arm, articulated at one of its ends provided at the other end with a preferentially parabolic reflector equipped with a preferentially halogen light source, capped with an external cover delimiting preferably a boom, the assembly can be seen at a distance of the order of a kilometer, the arm in operation is permanently animated by an alternating rotation movement oriented either on the right side to deviate to the right, or on the left side to deviate to the left, at the same time time the light source is lit, either continuously or discontinuously, during the descent of the arm, preferably with progressive switching on and off. The triple cumulation defined below
- du mouvement de haut en bas signifiant l'ordre de ralentir tel qu'il est pratiqué manuellement par les gendarmes- movement up and down signifying the order to slow down as practiced manually by the gendarmes
- du mouvement de gauche à droite ou vice versa- movement from left to right or vice versa
- de l'allumage continu voire discontinu est un message d'information à la fois fort et tranquille, immédiatement compréhensible par les usagers qui gèrent alors beaucoup mieux leur stress.- continuous or even discontinuous ignition is an information message that is both strong and quiet, immediately understandable by users, who then manage their stress much better.
Selon une adaptation le véhicule peut être équipé à l'arrière d'un ou plusieurs atténuateurs de choc fixes ou amovibles, éventuellement 3 l'un ou plusieurs étant relevables de sorte, après relèvement, & occuper une place réduite au garage et pendant le transport, a constituer un masque du système de signalisation et & banaliser le véhicule. Les atténuateurs peuvent être placés l'un au-dessus de l'autre, celui de dessus en retrait par rapport à celui de dessous, de manière à ce que le plus bas atténue les chocs des véhicules légers, le plue haut et le plus bas atténuent les choc des véhicules lourds.According to an adaptation, the vehicle can be equipped at the rear with one or more fixed or removable shock absorbers, possibly 3 one or more being liftable so, after recovery, & occupy a reduced space in the garage and during transport, to constitute a mask of the signaling system and to trivialize the vehicle. The attenuators can be placed one above the other, the one above recessed from the one below, so that the lower mitigates the shocks of light vehicles, the higher and lower reduce the impact of heavy vehicles.
Selon un autre usage, le dispositif permet de dévoyer la circulation de part et d'autre du véhicule porteur en créant l'oscillement alternatif de course réglable de part et d'autre du plan vertical passant par l'axe de rotation du bras.According to another use, the device makes it possible to divert the traffic on either side of the carrier vehicle by creating the alternative oscillation of travel adjustable on either side of the vertical plane passing through the axis of rotation of the arm.
Pour accroitre l'efficacité à longue et courte distance, le bras et son réflecteur peuvent se mouvoir par construction - d'une part latéralement hors du gabarit du véhicule généralement limité à 2,50 mètres et jusqu'à occuper au moins toute la largeur de la voie généralement limitée & 3,50 mètres ce qui autorise le montage d'un bras de distance entre axe et extrémité de l'ordre de 2,25 mètres.To increase efficiency at long and short distance, the arm and its reflector can move by construction - on the one hand laterally outside the vehicle gauge generally limited to 2.50 meters and until occupying at least the entire width of the track generally limited & 3.50 meters which allows the mounting of an arm distance between axis and end of the order of 2.25 meters.
- d'autre part au-dessus du gabarit de la route généralement limité à 4,50 m et alors sans limite latéral.- on the other hand above the gauge of the road generally limited to 4.50 m and then without lateral limit.
Selon une variante pour signaler encore plus haut, par exemple jusqu'à 7 mètres, l'axe de rotation du bras peut être monté sur une colonne mobile par exemple télescopique solidaire du châssis et/ou éventuellement translatable par exemple latéralement. Selon une autre variante le bras peut être équipé d'un ou plusieurs avants-bras ce qui autorise par combinaison des mouvements, tous les types de positionnement et de déplacement par exemple un mouvement d'alternement vertical au-dessus de la voie latérale. Selon une amélioration un capteur de présence d'obstacle, par exemple à ultra son ou à infra rouge, prêfêrentiellement installé au bout du bras permet de détecter par exemple le tablier d'un passage supérieur, ou un fil électrique et de déclencher automatiquement le retrait de la colonne ou du bras pour ramener ces éléments à l'intérieur des gabarits disponibles tout en assurant au delà de ces passages délicats le retour automatique ou manuel sur les positions initiales.According to a variant for signaling even higher, for example up to 7 meters, the axis of rotation of the arm can be mounted on a mobile column, for example telescopic, secured to the chassis and / or possibly translatable for example laterally. According to another variant, the arm can be equipped with one or more forearms, which allows, by combination of movements, all types of positioning and displacement, for example a vertical alternating movement above the lateral track. According to an improvement, an obstacle presence sensor, for example with ultrasound or infrared, preferably installed at the end of the arm, makes it possible to detect, for example, the apron of an overpass, or an electric wire and to automatically trigger the removal of the column or arm to bring these elements inside the available templates while ensuring beyond these delicate passages the automatic or manual return to the initial positions.
Selon une autre variante, le bras peut être dédoublé de manière symétrique, équilibrée, les deux bras sont alors solidaires, animés d'un mouvement de rotation pouvant êtreAccording to another variant, the arm can be split symmetrically, balanced, the two arms are then integral, driven in a rotational movement which can be
- d'une part continu dans un sens ou dans l'autre pour dévoyer à droite ou à gauche avec synchronisation de la mise en fonction alternative de l'une des deux sources lumineuses dans tout ou partie du secteur balayé de droite ou de gauche,- on the one hand continuous in one direction or the other to deviate to the right or to the left with synchronization of the alternative activation of one of the two light sources in all or part of the swept sector on the right or on the left,
- d'autre part alternatif par rapport à l'horizontale pour dévoyer aussi bien à droite qu'à gauche, avec une mise en fonction des sources lumineuses prêfêrentiellement continue mais aussi alternativement synchronisée. selon une autre adaptation complémentaire, le plan formé par le ou les bras qui est perpendiculaire à l'axe du véhicule peut être orienté autour d'un axe vertical par exemple l'axe de la colonne de manière à corriger en partie le défaut de parallaxe entre l'axe de la source lumineuse et l'axe de vision des usagers de la route notamment dans le cas d'une installation en virage de route. Cette orientation peut être réalisée manuellement ou automatiquement par une liaison mécanique branchée sur une bielle de la direction du véhicule ou tout autre système choisi par analogie avec les systèmes d'asservissement utilisés sur les véhicules à quatre roues directrices, mécaniques, électriques, électroniques. Selon une autre variante, la visibilité de la flèche peut être renforcée par la présence d'une visière, cette visière peut être tournante, par exemple autour du bord libre du bol contenant le réflecteur par exemple au moyen d'une couronne à bille et la position de la visière peut être asservie par l'intermédiaire de pignons ou courroie et de dents sur la couronne ou par l'intermédiaire d'un parallélogramme à une base fixée au niveau de l'axe du bras de sorte à conserver une même orientation de la visière quelque soit la position du bras. Un autre moyen est de lester simplement la visière en son point bas opposé.- on the other hand, alternative with respect to the horizontal to deviate both to the right and to the left, with the light sources preferably being switched on continuously but also alternately synchronized. according to another complementary adaptation, the plane formed by the arm (s) which is perpendicular to the axis of the vehicle can be oriented around a vertical axis, for example the axis of the column so as to partially correct the parallax defect between the axis of the light source and the axis of vision of road users, in particular in the case of an installation at a bend in the road. This orientation can be carried out manually or automatically by a mechanical link connected to a connecting rod of the vehicle steering or any other system chosen by analogy with the servo systems used on vehicles with four steered, mechanical, electric, electronic wheels. According to another variant, the visibility of the arrow can be reinforced by the presence of a visor, this visor can be rotatable, for example around the free edge of the bowl containing the reflector for example by means of a ball crown and the position of the visor can be controlled by means of pinions or belt and teeth on the crown or by means of a parallelogram to a base fixed at the level of the axis of the arm so as to maintain the same orientation of the visor whatever the position of the arm. Another way is to simply ballast the visor at its opposite low point.
Ces dispositions relatives à la visière peuvent être reconduites au cache extérieur délimitant partiellement la flèche de sorte à maintenir la flèche, par exemple à l'horizontale quelque soit la position du bras.These provisions relating to the visor can be extended to the external cover partially delimiting the arrow so as to maintain the arrow, for example horizontal whatever the position of the arm.
Le dispositif pour être réglementaire peut comporter un ou plusieurs panneaux type B 21, prêfêrentiellement placés sur l'atténuateur bas de sorte à les escamoter avec le relèvement des atténuateurs, banalisant ainsi le véhicule. L'optique adaptée sur le réflecteur peut être plane, elle peut aussi être constituée par une lentille de Fresnel de sorte à améliorer l'identification par les usagers.The device to be regulatory may include one or more type B 21 panels, preferably placed on the low attenuator so as to retract them with the raising of the attenuators, thus trivializing the vehicle. The adapted optics on the reflector can be flat, it can also be constituted by a Fresnel lens so as to improve identification by users.
La source lumineuse peut être composée de plusieurs sources, en particulier d'une source à éclat qui ne sera prêfêrentiellement déclenchée automatiquement que lorsque la Visibilité sera douteuse, toutes les sources pouvant être synchronisées à l'aide d'un automate dont l'incrémentation peut être faite par capteur ou par un secteur à came monté sur l'axe du bras rendant la synchronisation automatique tout en restant réglable par le déplacement des capteurs quelque soit l course choisie pour les battements des bras. Latéralement des glissières entourent le véhicule.The light source can be composed of several sources, in particular a flash source which will preferably be triggered automatically only when the Visibility is doubtful, all the sources being able to be synchronized using a automaton whose incrementation can be made by sensor or by a cam sector mounted on the axis of the arm making automatic synchronization while remaining adjustable by the displacement of the sensors whatever the stroke chosen for the beating of the arms. Side rails surround the vehicle.
Le bras peut être -équipé de projecteurs synchronisés avec l'éclairage de la source lumineuse de manière à renforcer l'effet de flèche. La figure 1 représente, vu par l'usager, le dispositif selon l'invention.The arm can be equipped with projectors synchronized with the lighting of the light source so as to reinforce the arrow effect. Figure 1 shows, seen by the user, the device according to the invention.
La figure 2 représente, latéralement ce dispositif.Figure 2 shows, laterally this device.
Le dispositif représenté sur les figures 1 et 2 comporte un véhicule (1) équipé d'un support (2) situé derrière la cabine munie dans sa partie haute d'un axe sensiblement horizontal (3) sur lequel s'articule un bras (4) portant à son extrémité un bol (5) de l'ordre de 0,80 m de diamètre, prêfêrentiellement de forme hémisphérique, ovoïdale et/ou cylindrique pourvu d'un réflecteur (6), d'une ou plusieurs sources lumineuses (7), d'une optique (8), d'un cache (9). La longueur entre axe du bras et son extrémité sur le bol est de l'ordre de 1,25 m jusqu'à 2,25 m et plus.The device shown in Figures 1 and 2 comprises a vehicle (1) equipped with a support (2) located behind the cabin provided in its upper part with a substantially horizontal axis (3) on which is articulated an arm (4 ) carrying at its end a bowl (5) of the order of 0.80 m in diameter, preferably hemispherical, ovoid and / or cylindrical in shape provided with a reflector (6), one or more light sources (7 ), an optic (8), a cover (9). The length between the axis of the arm and its end on the bowl is of the order of 1.25 m up to 2.25 m and more.
Un motoréducteur non représenté ou un vérin non représenté entraîne le bras dans un sens ou dans l'autre par l'intermédiaire d'un automate et d'une synchronisation par exemple par came et contacts tournants.A not shown gearmotor or a not shown actuator drives the arm in one direction or the other via a controller and synchronization, for example by cam and rotary contacts.
Sur le châssis du véhicule sont adaptés des axes transversaux (10) et (11) sur lesquels s'articulent deux atténuateurs (12) et (13) superposés décalés, un vérin (14) non représenté logé horizontalement dans l'axe du chassie assure le relevage simultané par le tirant (15) de l'atténuateur haut solidarisé à celui du bras par des ceintures et des bras latéraux (16) articulés, constitués de simples plats de manière à ne pas transmettre de contrainte sans choc.On the chassis of the vehicle are adapted transverse axes (10) and (11) on which are articulated two attenuators (12) and (13) superimposed offset, a jack (14) not shown housed horizontally in the axis of the chase ensures the simultaneous lifting by the tie rod (15) of the high attenuator secured to that of the arm by belts and lateral arms (16) articulated, consisting of simple plates so as not to transmit stress without shock.
Les pointillés sur les figures 1 et 2 sont représentatifs sans signification exclusive de positions de transport du bras et des atténuateurs. Selon une autre variante, non représentée par une figure, les lampes habituellement utilisées étant halogènes peuvent être remplacées par des lampes tubulaireβ au sodium prêfêrentiellement de basse pression qui ont la caractéristique d'être de couleur jaune plutôt orangé, ce qui procure de très nombreux avantages :The dotted lines in Figures 1 and 2 are representative without exclusive significance of transport positions of the arm and the attenuators. According to another variant, not shown in a figure, the lamps usually used being halogen can be replaced by tubular beta sodium preferential low pressure lamps which have the characteristic of being yellow rather orange in color, which provides many advantages :
- économie d'un filtre et surtout d'un gain lumineux très important de 25 à 100 % absorbé habituellement par le filtre,- saving a filter and especially a very large light gain of 25 to 100% usually absorbed by the filter,
- rendement exceptionnel du signal, par exemple une lampe sodium basse pression de 66 W fournit 10 700 lumens alors qu'une lampe halogène de 75 W fournit 1 130 lumens,- exceptional signal performance, for example a 66 W low pressure sodium lamp provides 10,700 lumens while a 75 W halogen lamp provides 1,130 lumens,
- visibilité sous tous les angles sans perte de rendement c'est dire que le dispositif est installable en courbe,- visibility from all angles without loss of performance, that is to say that the device can be installed in a curve,
- visibilité à l'avant comme à l'arrière en plaçant les lampes sodium sans bol, sans enceinte ou dans une enceinte transparente, par exemple une sphère particulièrement aérodynamique et très design autorisant l'utilisation du dispositif sur chaussées bidirectionnelles,- visibility at the front as at the rear by placing the sodium lamps without bowl, without enclosure or in a transparent enclosure, for example a particularly aerodynamic and very design sphere allowing the use of the device on two-way pavements,
- définition d'un tracé ou d'un contour rectiligne voire courbe par juxtapositions unitaires ou bout à bout, par exemple pour former une flèche, des sources lumineuses constituées par des tubes le plus souvent retournés sur eux-mêmes en forme de U donc linéraires,- definition of a straight line or even curved outline by unitary or end-to-end juxtapositions, for example to form an arrow, light sources constituted by tubes generally turned over on themselves in a U shape therefore linear ,
- optimisation de l'épaisseur vue du tube en U en jouant sur son orientation par rapport à son axe,,- optimization of the thickness seen from the U-shaped tube by adjusting its orientation relative to its axis,
- faible puissance installée, une flèche de 1,50 mètres pouvant être par exemple composée de 7 lampes de 35 W de 50 centimètres de diamètre de 300 mm de longueur unitaire, soit 245 watts ou 30 000 lumens, visible à plus d'un kilomètre de distance. L'amorçage des lampes sodium est long de l'ordre de 10 minutes, ce n'est pas là un inconvénient car ce délai reste inférieur le plus souvent au temps de déplacement. La coupure de une à quelques secondes et le rêamorçage instantané sont possibles par le montage suivant à partir d'une batterie de courant continu de 12 ou 24 volts en associant :- low installed power, a boom of 1.50 meters which can for example be composed of 7 lamps of 35 W of 50 centimeters in diameter with 300 mm of unit length, that is 245 watts or 30,000 lumens, visible from more than one kilometer distance. The ignition of sodium lamps is long on the order of 10 minutes, this is not a drawback because this period remains less often than travel time. Switching off for one to a few seconds and instant re-ignition are possible by the following assembly from a 12 or 24 volt DC battery by combining:
- un onduleur de tension alternative ou de signal sinusoïdal carré,- an alternating voltage or square sine wave inverter,
- un convertisseur de puissance adaptable,- an adaptable power converter,
- un dispositif de réduction d'intensité manuel ou automatique couplé à une cellule de mesure de la luminosité.- a manual or automatic intensity reduction device coupled to a brightness measurement cell.
La batterie peut être remplacée par un groupe électrogène à courant alternatif éliminant l'onduleur.The battery can be replaced by an alternating current generator eliminating the inverter.
Selon une adaptation complémentaire, une source lumineuse nouvelle unique prêfêrentiellement peut être montée sur une nouvelle colonne têlescopique indépendante plaçant la susdite source très haut au-dessus du véhicule pour le présignaler.According to an additional adaptation, a single new light source preferably can be mounted on a new independent telescopic column placing the above source very high above the vehicle to signal it.
Selon d'autres adaptations, les lampes sodium prêfêrentiellement basse pression peuvent être utilisées pour signaler des lieux, par exemple chantier, zone d'accident, point noir,... Cette signalisation pourrait être fixe ou animée, pouvant représenter des symboles ou simplement se suffire par son tube éclairant en particulier positionné verticalement affirmant sa singularité et offrant une faible prise au vent. According to other adaptations, preferably low pressure sodium lamps can be used to signal places, for example construction site, accident zone, black dot, ... This signaling could be fixed or animated, being able to represent symbols or simply suffice with its illuminating tube, in particular positioned vertically, asserting its singularity and offering low wind resistance.
