Abstract
Description
PORTIQUE DE CONTROLE DE LA CIRCULATION L'invention se rapporte à un portique de contrôle du passage d'un véhicule en fonction de sa taille. Il est connu de limiter l'accès à un lieu pour certains véhicules au moyen de sa taille. The invention relates to a gantry for controlling the passage of a vehicle according to its size. It is known to limit the access to a place for certain vehicles by means of its size.
On utilise à cet effet un portique en U retourné dont notamment la hauteur de la barre transversale est déterminée pour ne laisser passer que les véhicules, par exemple, ayant une hauteur inférieure à celle d'un camping car ou d'une caravane. Cette barre transversale est souvent montée mobile afin de pouvoir être escamotée si nécessaire, par exemple pour-les pompiers. For this purpose is used an inverted U-shaped gantry including the height of the crossbar is determined to let only vehicles, for example, having a height lower than that of a camper or a caravan. This crossbar is often mounted so that it can be retracted if necessary, for example firefighters.
Pour cela la barre transversale est, par exemple, montée pivotante par rapport à un axe confondu avec l'axe vertical d'un montant du portique. La manoeuvre se fait manuellement. Le poids de cette barre souvent tubulaire et en acier n'est pas propice à la manoeuvre. Par ailleurs le porte à faux entraine rapidement des difficultés car l'axe s'use 15 prématurément. On connait également des systèmes de manoeuvre à crémaillère permettant de faire coulisser latéralement la barre transversale. La barre est équipée d'une crémaillère qui engrène avec une roue à dents. Le système est plus complexe que le précédent et nécessite de disposer latéralement de la place suffisante pour la translation de la barre. 20 Il est également connu de loger dans les montants des moyens moteurs permettant de lever ou abaisser la barre transversale. Cela présente une difficulté car les moteurs doivent être synchronisés sous peine de coincement ( effet tiroir). Egalement en cas de choc sur un montant ou sur la barre, le système se coince L'invention se propose une nouvelle solution plus simple. 25 A cet effet, l'invention a pour objet un portique de contrôle du passage d'un véhicule en regard de sa taille comprenant un obstacle mobile en hauteur caractérisé en ce que l'obstacle est associé à un bras pivotant. L'invention sera bien comprise à l'aide de la description ci après faite à titre d'exemple non limitatif en regard du dessin qui représente schématiquement : 30 FIG I : Un portique selon l'invention vue de face FIG 2 : Une vue latérale du portique selon l'invention. FIG 3 : Une vue d'une variante En se reportant au dessin, on voit un portiquel de contrôle du passage d'un véhicule en regard de sa taille comprenant un obstacle 2 mobile en hauteur . Il comprend deux montants 3 et une traverse 4 reliant les deux montants. Il se positionne au dessus d'une route. For this purpose the transverse bar is, for example, pivotally mounted relative to an axis coinciding with the vertical axis of an amount of the gantry. The maneuver is done manually. The weight of this bar is often tubular and steel is not conducive to maneuvering. Furthermore the overhang quickly causes difficulties because the axis wears 15 prematurely. Racking maneuvering systems are also known for sliding the lateral bar laterally. The bar is equipped with a rack which meshes with a wheel with teeth. The system is more complex than the previous one and requires to have laterally sufficient space for the translation of the bar. It is also known to house in the amounts of motor means for raising or lowering the crossbar. This presents a difficulty because the motors must be synchronized at the risk of jamming (drawer effect). Also in case of impact on an amount or on the bar, the system gets stuck The invention proposes a new, simpler solution. For this purpose, the subject of the invention is a gantry for controlling the passage of a vehicle facing its height, comprising a mobile obstacle in height, characterized in that the obstacle is associated with a pivoting arm. The invention will be better understood from the following description given by way of nonlimiting example with reference to the drawing which shows schematically: FIG. 1: A gantry according to the invention seen from the front FIG. of the gantry according to the invention. FIG. 3: A view of a variant Referring to the drawing, there is shown a portion of control of the passage of a vehicle facing its size including an obstacle 2 movable in height. It comprises two uprights 3 and a crossbar 4 connecting the two uprights. It is positioned above a road.
L'obstacle est associé à un bras 5 pivotant autour d'un axe qui ici est transversal à l'axe de la route (Figure 3). Le bras 5 sert de contre poids. Dans une variante, non représentée, le bras et l'obstacle qui sont associés rigidement sont montés en sorte de pouvoir tourner sur 360°. L'axe de rotation est alors confondu avec l'axe de la traverse 4. The obstacle is associated with an arm 5 pivoting about an axis which here is transverse to the axis of the road (Figure 3). The arm 5 serves as a counterweight. In a variant, not shown, the arm and the obstacle which are rigidly associated are mounted so as to rotate 360 °. The axis of rotation is then coincident with the axis of the crossbar 4.
Avantageusement, l'obstacle est suspendu à une extrémité d'un bras mais de préférence, il est suspendu à l'une des extrémités d'un levier, l'autre extrémité du levier porte alors un contrepoids 6 et l'axe 7 de pivot se situe entre les deux extrémités. Le contrepoids compense au moins le poids de l'obstacle de sorte que l'effort pour la motorisation sera faible. De préférence le contrepoids est légèrement plus lourd pour qu'en cas de panne il n'y ait pas d'effet guillotine car l'obstacle va nécessairement dans le sens de la levée. Plus précisément c'est la combinaison du poids de ce contrepoids et la distance par rapport à l'axe d'articulation qui va développer un moment de force suffisant pour lever l'obstacle. Advantageously, the obstacle is suspended at one end of an arm but preferably it is suspended at one end of a lever, the other end of the lever then carries a counterweight 6 and the pivot axis 7 is between the two ends. The counterweight at least compensates for the weight of the obstacle so that the effort for the engine will be low. Preferably the counterweight is slightly heavier so that in case of failure there is no guillotine effect because the obstacle is necessarily in the direction of lifting. More precisely it is the combination of the weight of this counterweight and the distance relative to the hinge axis that will develop a moment of force sufficient to lift the obstacle.
L'obstacle 2 est un panneau articulé sur le bras. Par exemple, la longueur, la forme du bras et la hauteur du panneau, sont définies pour que le bas du panneau puisse être amené quasiment au contact de la route afin de fermer le passage. Le bras est en L c'est-à-dire comprend une grande branche A articulée sur la traverse 25 et un petite branche B servant de suspente au panneau. Pour une bonne stabilité, le bras 5 est composé de deux éléments longitudinaux reliés par des entretoises formant ainsi un cadre. Le panneau présente à sa base une encoche 10 pour définir un gabarit pour un type de véhicule. 30 Le gabarit maximal est donné par la position angulaire de la poutre servant de point d'articulation. Un avantage de ce panneau suspendu est qu'un véhicule peut le percuter sans pour autant abimer la structure porteuse. The obstacle 2 is a hinged panel on the arm. For example, the length, the shape of the arm and the height of the panel, are defined so that the bottom of the panel can be brought almost in contact with the road to close the passage. The arm is L-shaped, that is to say includes a large branch A articulated on the crosspiece 25 and a small branch B serving as a suspension panel. For good stability, the arm 5 is composed of two longitudinal elements connected by spacers forming a frame. The panel has at its base a notch 10 to define a template for a type of vehicle. The maximum gauge is given by the angular position of the beam serving as the point of articulation. An advantage of this suspended panel is that a vehicle can hit it without damaging the supporting structure.
Ce panneau est associé au bras par deux articulations 7A. L'entrainement se fait soit avec un moteur électrique soit avec un moteur hydraulique (non représenté). Avec la solution hydraulique et un contrepoids plus lourd que l'obstacle, les pompiers pourront intervenir sur le circuit hydraulique avec un code ou une clé qui va relâcher la pression ce qui va produire une levée de l'obstacle sans nécessité de faire tourner la pompe hydraulique. C'est un gage de sécurité en cas de coupure d'électricité ou de panne sur la pompe. On notera que le portique de la figure 3 montre une combinaison de panneau réglant 10 divers gabarits. This panel is associated with the arm by two joints 7A. The training is done either with an electric motor or with a hydraulic motor (not shown). With the hydraulic solution and a counterweight heavier than the obstacle, firefighters can intervene on the hydraulic circuit with a code or a key that will release the pressure which will produce a lifting of the obstacle without the need to turn the pump hydraulic. This is a guarantee of safety in case of power failure or failure on the pump. It will be noted that the gantry of FIG. 3 shows a combination of panels regulating various jigs.
