Par exemple, de tels portails automatiques peuvent présenter divers aspects en étant coulissant ou en présentant au moins un battant s'ouvrant par pivotement autour d'un axe. Il existe de nombreuses applications de tels portails, comme portails de résidence, portails d'entrée d'usine ou diverses formes de barrières.For example, such automatic gates may have various aspects being slidable or having at least one flap opening by pivoting about an axis. There are many applications of such portals, such as residential portals, factory entry gates or various forms of gates.

L'ouverture et la fermeture d'un tel portail automatique sont fréquemment automatisées pour faciliter l'entrée de véhicules ou de personnes à l'intérieur de l'espace délimité qu'il ferme, ceci pour des raisons de commodité. L'ouverture du portail peut se faire par télécommande sans que le conducteur ne descende de son véhicule pour ouvrir lui-même manuellement le portail en le manoeuvrant.The opening and closing of such an automatic gate are frequently automated to facilitate the entry of vehicles or people inside the delimited space it closes, for reasons of convenience. The opening of the gate can be done by remote control without the driver descends from his vehicle to manually open the gate by maneuvering.

Cependant, ceci implique la présence de moyens de détection pouvant détecter la présence d'au moins un objet dans la zone de déplacement de ladite au moins portion mobile du portail aussi bien lors de son ouverture que de sa fermeture afin que le portail ne puisse rentrer en collision avec ledit au moins un objet. Il existe aussi des risques de coincement du portail lors de son déplacement, auquel cas il convient d'arrêter les moyens d'entraînement du portail ou d'inverser le sens de son déplacement pour ne pas l'endommager.However, this implies the presence of detection means that can detect the presence of at least one object in the zone of movement of said at least movable portion of the gate as well when it opens or closed so that the gate can not enter. in collision with the at least one object. There are also risks of jamming of the gate during its movement, in which case it is necessary to stop the drive means of the gate or to reverse the direction of its movement to not damage it.

Habituellement, les portails automatiques sont équipés d'au moins une cellule photoélectrique émettrice émettant un faisceau lumineux vers une cellule photoélectrique réceptrice. Une rupture du faisceau indique une présence et empêche la fermeture du portail par au moins l'arrêt du mouvement de fermeture.Usually, automatic gates are equipped with at least one transmitting photocell emitting a light beam to a receiving photocell. A break in the beam indicates a presence and prevents closing of the gate by at least stopping the closing movement.

Pour les portails à vantail coulissant, pour lequel le risque de coincement du portail lors de son déplacement est plus grand que pour d'autres types de portail, ceux-ci peuvent être munis de telles cellules photoélectriques avec en plus des capteurs de contact et/ou des limiteurs du couple des moyens d'entraînement pour éviter les coincements entre vantail et montant fixe des portails. Ceci est illustré notamment par le document FR-A-2 731 741 .For gates with sliding leaf, for which the risk of jamming of the gate during its movement is greater than for other types of gate, they can be provided with such photocells with in addition to contact sensors and / or torque limiters drive means to prevent jamming between leaf and fixed amount of gates. This is illustrated in particular by the document FR-A-2,731,741 .

Le désavantage de telles mesures est que la zone de déplacement surveillée est étroite. Par exemple, cette zone est limitée à une ligne à hauteur faible ce qui n'exclut pas des non-détections par exemple pour des véhicules à forte garde au sol. Bien souvent, la zone de détection est limitée à une ligne s'étendant sensiblement horizontalement dans le passage fermé ou ouvert par le portail, cette ligne ne permettant pas de détecter au-dessus ou en dessous d'elle des possibles collisions du portail avec au moins un objet se trouvant dans le passage.The disadvantage of such measures is that the monitored movement area is narrow. For example, this zone is limited to a line at low height which does not exclude non-detections for example for vehicles with high ground clearance. Very often, the detection zone is limited to a line extending substantially horizontally in the closed passageway or opened by the portal, this line not making it possible to detect above or below it possible collisions of the portal with the least one object in the passage.

Le problème à la base de la présente invention est de munir un portail automatique extérieur de moyens de détection améliorés d'un objet pouvant se trouver dans la zone de déplacement du portail lors de son ouverture ou de sa fermeture. En particulier, l'invention propose pour résoudre ce problème des moyens de détection pouvant couvrir sensiblement la zone de déplacement du portail sur toute la hauteur du portail et avantageusement sur toute sa largeur, par exemple sur 10 mètres voire plus.The problem underlying the present invention is to provide an external automatic gate improved detection means of an object that can be in the gate of the movement zone when opening or closing.

De manière générale, la présente invention se réfère à un portail automatique extérieur 1, 1a muni d'au moins un scanner 2 pour la sécurisation de l'ouverture et de la fermeture du portail automatique extérieur, ledit au moins un scanner 2 étant disposé en hauteur sur une portion mobile 3 du portail 1 ou sur une partie fixe encadrant le portail 1, 1a, par exemple ses montants fixes 4, 4a, 4b (pouvant encore être appelés portique) délimitant le passage de l'espace délimité que le portail 1, 1a ouvre ou ferme.In general, the present invention refers to an external automatic gate 1, 1a provided with at least one scanner 2 for securing the opening and closing of the automatic gate, said at least one scanner 2 being disposed in height on a movable portion 3 of the gate 1 or on a fixed portion flanking the portal 1, 1a, for example its fixed amounts 4, 4a, 4b (can still be called gantry) delimiting the passage of the delimited space that the portal 1 , 1a open or close.

Aux figures 1, 1a et 2, le portail automatique extérieur est un portail à battant 1 tandis qu'aux figures 3, 3a et 4, le portail automatique extérieur est un portail coulissant 1a. La portion mobile 3, 3a du portail 1, 1a est mobile dans une zone de déplacement d'une position d'ouverture à une position de fermeture d'un passage dans un espace délimité fermé par le portail 1, 1a et inversement.To the Figures 1, 1a and 2 , the automatic gate is a swing gate 1 Figures 3, 3a and 4 , the automatic gate is a sliding gate 1a. The movable portion 3, 3a of the gate 1, 1a is movable in a displacement zone from an open position to a closed position of a passage in a delimited space closed by the gate 1, 1a and vice versa.

Sans ce que cela soit limitatif, comme il est montré aux figures 1 et 3, le portail automatique extérieur 1, 1a peut comporter une suite de barreaux verticaux, dont un seul est référencé 13. A ces figures, les barreaux 13 s'étendent entre une poutre supérieure 14 et une poutre inférieure 15 délimitant le portail automatique extérieur 1, 1a en haut et en bas.Without this being limiting, as it is shown to figures 1 and 3 the external automatic gate 1, 1a may comprise a series of vertical bars, of which only one is referenced 13. In these figures, the bars 13 extend between an upper beam 14 and a lower beam 15 delimiting the external automatic gate 1, 1a up and down.

En regard des figures 1, 1a et 2, le portail à battant 1 illustré comprend deux battants 3 se rejoignant en étant alignés l'un à l'autre en position fermée du portail 1, les battants formant alors la portion mobile du portail 1. Sur chaque extrémité des battants 3 pointant l'une vers l'autre, il est prévu une butée de fin de course 5 permettant de vérifier l'alignement des battants 3 dans la position de fermeture du portail 1.With regard to Figures 1, 1a and 2 , the swing gate 1 illustrated comprises two leaves 3 joining by being aligned with each other in the closed position of the gate 1, the leaves then forming the movable portion of the gate 1. On each end of the leaves 3 pointing the towards each other, there is provided a limit stop 5 for verifying the alignment of the leaves 3 in the closed position of the gate 1.

Chaque battant 3 est solidarisé à un montant 4 fixe par son extrémité qui lui est adjacente, ce montant 4 fixe pouvant être sous la forme d'un poteau 4. Chaque poteau 4 fixe est sensiblement vertical et forme au moins partiellement l'encadrement latéral du portail à battant 1 sur chacun de ses côtés.Each leaf 3 is secured to a fixed upright 4 by its adjacent end, this fixed upright 4 being in the form of a pole 4. Each fixed pole 4 is substantially vertical and forms at least partially the lateral frame of the swing gate 1 on each of its sides.

Chaque battant 3 peut pivoter automatiquement autour de son poteau 4 fixe, les deux battants 3 pointant vers l'intérieur ou l'extérieur de l'espace fermé par le portail 1. Ceci peut entraîner un risque de collision avec un objet se trouvant sur le passage d'au moins un battant 3 lors de son pivotement, ceci aussi bien lors de l'ouverture que de la fermeture du portail à battant 1.Each wing 3 can pivot automatically around its fixed post 4, the two leaves 3 pointing inwards or outwards of the space closed by the gate 1. This can lead to a risk of collision with an object on the passage of at least one leaf 3 during its pivoting, this as well when opening or closing the swing gate 1.

Le pivotement autour du poteau 4 fixe respectif de chaque battant 3, est obtenu sous l'action d'un bras 6 motorisé par des moyens de pivotement servant de moyens d'entraînement du battant 3. Ces moyens de pivotement tirent chaque battant 3 lors de l'ouverture et le poussent lors de la fermeture du portail à battant 1.The pivoting around the respective fixed post 4 of each leaf 3, is obtained under the action of an arm 6 powered by pivoting means serving as drive means of the leaf 3. These pivoting means pull each leaf 3 when opening and push it when closing the swing gate 1.

Des roulements à billes inférieur 7 et supérieur 7a sont avantageusement prévus entre chaque battant 3 et la partie inférieure ou respectivement supérieure du poteau 4 fixe qui lui est associé. Ces roulements 7, 7a permettent le pivotement de chaque battant 3 par rapport à son poteau 4 fixe associé.Lower and upper ball bearings 7a and 7a are advantageously provided between each leaf 3 and the lower or upper part of the fixed post 4 associated therewith. These bearings 7, 7a allow the pivoting of each leaf 3 relative to its associated fixed post 4.

En regard des figures 3, 3a et 4, le mode de réalisation d'un portail coulissant 1a comprend un panneau 3a en tant que portion mobile du portail 1a monté sur roues, aux figures 3 et 4 deux roues, ce qui n'est pas limitatif. Ces roues coopèrent avantageusement avec une surface de guidage, par exemple un rail disposé sur le sol pour l'ouverture ou la fermeture du portail 1a.With regard to Figures 3, 3a and 4 , the embodiment of a sliding gate 1a comprises a panel 3a as a movable portion of the gate 1a mounted on wheels, to Figures 3 and 4 two wheels, which is not limiting. These wheels advantageously cooperate with a guide surface, for example a rail disposed on the ground for opening or closing the gate 1a.

En position fermée, le portail 1a est délimité par deux montants 4a, 4b fixes formant l'encadrement latéral du portail coulissant 1a sur chacun de ses côtés, ces montants 4a, 4b fixes étant avantageusement sous la forme de poteaux.In the closed position, the gate 1a is delimited by two fixed uprights 4a, 4b forming the lateral frame of the sliding gate 1a on each of its sides, these uprights 4a, 4b fixed being advantageously in the form of poles.

Lors de son déplacement pour l'ouverture du portail 1a, le panneau 3a coulisse automatiquement en direction d'un des poteaux 4a, 4b fixes, aux figures 3 et 4 le premier poteau 4a et passe à travers ce premier poteau 4a pour être complètement escamoté le long d'une surface fermée se trouvant de ce côté du premier poteau 4a fixe, cette surface fermée étant ci-après dénommée mur, ce qui n'est pas limitatif. Le panneau 3a peut aussi ne pas traverser le premier poteau 4a en tant que montant fixe mais coulisser à l'extérieur de ce montant transversalement à celui-ci.When moving for the opening of the gate 1a, the panel 3a automatically slides towards one of the fixed posts 4a, 4b, the Figures 3 and 4 the first pole 4a and passes through this first pole 4a to be completely retracted along a closed surface lying this side of the first post 4a fixed, this closed surface is hereinafter called wall, which is not limiting. The panel 3a may also not pass through the first post 4a as a fixed post but slide outside this post transversely thereto.

Ce déplacement est accompli par des moyens d'entraînement 11 du portail 1a comprenant avantageusement une crémaillère portée latéralement vers la partie inférieure du portail 1a sur toute la longueur du portail 1a coopérant avec des moyens d'entraînement 11. La coopération des moyens d'entraînement 11 avec la crémaillère permet l'entraînement du portail automatique extérieur 1a aussi bien lors de l'ouverture que de la fermeture du portail 1a.This displacement is accomplished by drive means 11 of the gate 1a advantageously comprising a rack carried laterally towards the lower part of the gate 1a over the entire length of the gate 1a cooperating with drive means 11. The cooperation of the drive means 11 with the rack allows the drive of the external automatic gate 1a both at the opening and closing of the gate 1a.

Dans ce qui va suivre, pour un portail coulissant 1a, il sera fait référence à extrémité avant pour son extrémité latérale pénétrant en premier le long du mur à travers ou transversalement au premier poteau 4a fixe et à extrémité arrière pour l'autre extrémité latérale venant en butée contre le second poteau 4b fixe lors de la fermeture du portail coulissant 1a.In what follows, for a sliding gate 1a, reference will be made to the front end for its lateral end penetrating first along the wall through or transversely to the first fixed post 4a and rear end for the other lateral end in abutment against the second fixed pole 4b when closing the sliding gate 1a.

Pour un tel portail coulissant 1a, il peut être prévu une butée de fermeture 10 signalant la fermeture du portail 1a et portée par le second poteau 4b fixe non traversé par le panneau 3a du portail 1a. Il peut aussi être prévu une butée d'ouverture 10a signalant l'ouverture du portail 1a, le panneau 3a ayant alors traversé ou coulissé le long du premier poteau 4a fixe et ayant aussi coulissé le long du mur bordant le côté latéral de l'encadrement du portail 1a comportant le premier poteau 4a fixe. La butée d'ouverture 10a est avantageusement disposée dans le mur en fin de course du panneau 3a, le panneau 3a ayant complètement été rentré le long du mur.For such a sliding gate 1a, there can be provided a closure stop 10 signaling the closing of the gate 1a and carried by the second fixed post 4b not traversed by the panel 3a of the gate 1a. It can also be provided an opening stop 10a signaling the opening of the gate 1a, the panel 3a having then traversed or slid along the first fixed post 4a and having also slid along the wall bordering the lateral side of the frame portal 1a having the first fixed post 4a. The opening stop 10a is advantageously arranged in the end-of-travel wall of the panel 3a, the panel 3a having been completely retracted along the wall.

Il est à garder à l'esprit que ces deux modes de portail automatique extérieur montrés aux figures ne sont pas limitatifs pour la présente invention et qu'au moins un scanner 2 peut aussi être associé à d'autres portails automatiques.It should be borne in mind that these two modes of external automatic gate shown in the figures are not limiting for the present invention and that at least one scanner 2 can also be associated with other automatic gates.

Comme exemple d'un autre mode de réalisation d'un portail à battant 1, si aux figures 1, 1a et 2 le portail à battant 1 comprend deux battants 3 pivotants, le portail à battant peut ne comprendre qu'un unique battant pivotant. Ce mode de réalisation n'est pas montré aux figures.As an example of another embodiment of a swing gate 1, if Figures 1, 1a and 2 the swing gate 1 comprises two pivoting wings 3, the swing gate may comprise a single pivoting leaf. This embodiment is not shown in the figures.

Comme exemple d'un autre mode de réalisation d'un portail coulissant 1 a, si aux figures 3, 3a et 4 le portail coulissant 1 a est en une seule partie en ne présentant qu'un panneau et s'ouvre par coulissement du panneau vers un seul côté latéral de l'encadrement du portail, il est aussi possible que le portail coulissant se compose de deux panneaux sensiblement équivalents s'ouvrant par des coulissements de sens opposé.As an example of another embodiment of a sliding gate 1a, if Figures 3, 3a and 4 the sliding gate 1a is in one part with only one panel and opens by sliding the panel to only one lateral side of the frame of the gate, it is also possible that the sliding gate consists of two panels substantially equivalent opening by sliding in the opposite direction.

Ces deux panneaux se rejoignent au milieu du passage du portail dans sa position de fermeture tandis que chaque panneau rentre dans son côté latéral associé en s'éloignant l'un de l'autre, les montants fixes, avantageusement sous la forme de poteaux fixes étant alors symétriques et traversés respectivement par un des deux panneaux. Ce mode de réalisation n'est pas montré aux figures.These two panels meet in the middle of the passage of the gate in its closed position while each panel enters its associated lateral side moving away from each other, the fixed amounts, preferably in the form of fixed posts being then symmetrical and traversed respectively by one of the two panels. This embodiment is not shown in the figures.

Comme autre exemple d'un portail automatique extérieur, selon un mode de réalisation non montré aux figures, le portail automatique extérieur peut être un portail basculant, le portail se soulevant en pivotant autour d'un axe s'étendant sur son bord supérieur, le bord supérieur du portail pouvant en outre coulisser pour passer de l'autre côté de l'encadrement que celui dans lequel il se soulève.As another example of an external automatic gate, according to an embodiment not shown in the figures, the external automatic gate may be a tilting gate, the gate being lifted by pivoting about an axis extending on its upper edge, the upper edge of the gate can also slide to pass on the other side of the frame that in which it lifts.

Comme autre exemple d'un portail automatique extérieur, le portail peut être un portail comprenant plusieurs panneaux tournant autour d'un axe vertical qui est disposé au milieu des panneaux, les panneaux s'étendant radialement.As another example of an automatic gate outside, the portal may be a portal comprising several panels rotating about a vertical axis which is arranged in the middle of the panels, the panels extending radially.

Pour les deux modes de réalisation de l'invention montrés aux figures et pour les modes dérivés relatifs à l'ouverture et à la fermeture d'un portail automatique extérieur, il est prévu de disposer au moins un scanner 2 pour le portail 1, 1a, soit sur sa portion mobile 3, 3a ou soit sur un élément fixe, par exemple un montant 4, 4a, 4b fixe, avantageusement un poteau fixe vertical réalisant un côté de l'encadrement du portail 1, 1a. Ledit au moins un scanner 2 est disposé en hauteur avantageusement sur le bord supérieur du portail 1, 1a ou d'un montant 4, 4a fixe vertical. Le scanner est donc situé de sorte à produire une projection de faisceau(x) de détection vers le bas, en direction d'une portion du sol située au voisinage de la portion mobile. Avantageusement, le scanner est localisé au point haut du portail ou à proximité immédiate de celui-ci, de sorte à offrir une détection sur l'intégralité de la hauteur des parties mobiles du portail. Pour les mêmes raisons, il est préféré que le scanner soit placé à une extrémité latérale de la portion mobile, de sorte à couvrir toute sa largeur. Ainsi, le scanner est avantageusement à une extrémité supérieure du portail.For the two embodiments of the invention shown in the figures and for the derived modes relating to the opening and closing of an automatic gate outside, it is expected to have at least one scanner 2 for the portal 1, 1a either on its movable portion 3, 3a or on a fixed element, for example a fixed amount 4, 4a, 4b, preferably a vertical fixed pole forming a side of the frame of the gate 1, 1a. Said at least one scanner 2 is arranged in height advantageously on the upper edge of the gate 1, 1a or a vertical upright 4, 4a. The scanner is thus located to produce a detection beam projection (x) downward towards a portion of the ground located in the vicinity of the movable portion. Advantageously, the scanner is located at the high point of the portal or in the immediate vicinity of the latter, so as to offer detection on the whole of the height of the moving parts of the gate. For the same reasons, it is preferred that the scanner be placed at a lateral end of the movable portion so as to cover its entire width. Thus, the scanner is advantageously at an upper end of the portal.

Avantageusement, ledit au moins un montant 4, 4a est sous forme d'un poteau creux, les connections électriques dudit au moins un scanner 2 passant à l'intérieur dudit poteau 4, 4a. Ceci permet de restreindre le câblage et de le protéger en le plaçant à l'intérieur du poteau 4, 4a. Le temps de pose est ainsi diminué avec suppression de nombreux câbles et fourreaux électriques et l'inutilité de pratiquer des saignées pour le passage des câbles. Ceci diminue le coût du montage du portail 1, 1a et facilite la recherche possible des pannes en service après-vente.Advantageously, said at least one post 4, 4a is in the form of a hollow post, the electrical connections of said at least one scanner 2 passing inside said post 4, 4a. This makes it possible to restrict the wiring and to protect it by placing it inside the pole 4, 4a. The exposure time is thus reduced with the removal of many cables and electrical sleeves and the need for slitting for the passage of cables. This reduces the cost of mounting the portal 1, 1a and facilitates the possible search for breakdowns in after-sales service.

Ledit au moins un scanner 2 est donc disposé en hauteur vers une extrémité du passage que ferme ou ouvre le portail 1, 1a, le scanner 2 générant au moins un plan de balayage 8 longeant au moins partiellement la zone de déplacement de ladite au moins une portion mobile 3, 3a en étant sensiblement vertical ou formant un angle aigu par rapport à un plan vertical contenant la portion mobile 3, 3a.Said at least one scanner 2 is thus arranged in height towards one end of the passage that closes or opens the gate 1, 1a, the scanner 2 generating at least one scanning plane 8 at least partially along the displacement zone of said at least one movable portion 3, 3a being substantially vertical or forming an acute angle with respect to a vertical plane containing the movable portion 3, 3a.

En se référant aux figures 1 à 4, ledit au moins un scanner est avantageusement un scanner 2 laser. De manière classique un tel scanner 2 comprend comme cellule émettrice une diode, avantageusement une diode laser qui émet un faisceau lumineux, avantageusement par intermittence.Referring to Figures 1 to 4 said at least one scanner is advantageously a laser scanner. Conventionally, such a scanner 2 comprises as transmitting cell a diode, advantageously a laser diode which emits a light beam, advantageously intermittently.

Le faisceau lumineux émis est dirigé vers une zone spécifique dans laquelle il existe un risque de collision du portail 1, 1a alors en train de s'ouvrir ou de se fermer avec un ou des objets. Si le faisceau lumineux rencontre un objet, ce faisceau lumineux est réfléchi par l'objet.The emitted light beam is directed to a specific area in which there is a risk of collision of the portal 1, 1a while opening or closing with one or more objects. If the light beam encounters an object, this light beam is reflected by the object.

Le scanner 2 comprend aussi une cellule réceptrice, avantageusement sous la forme d'une photodiode qui reçoit ensuite la lumière réfléchie. Selon la distance entre le scanner 2 et l'objet, le temps de parcours du faisceau lumineux peut varier et ce temps de parcours peut être mesuré par un microprocesseur intégré dans ou associé au scanner 2. Il peut en être déduit que le faisceau lumineux a rencontré un objet sur son parcours.The scanner 2 also comprises a receiver cell, advantageously in the form of a photodiode which then receives the reflected light. Depending on the distance between the scanner 2 and the object, the travel time of the light beam can vary and this travel time can be measured by a microprocessor integrated in or associated with the scanner 2. It can be deduced that the light beam has encountered an object on his course.

Le temps de parcours du faisceau peut permettre de calculer la distance entre l'objet et le scanner 2 et donc de calculer la distance entre l'objet et le portail 1, 1a automatique extérieur. Un scanner 2 peut être avantageusement capable de balayer une surface prédéfinie grâce à un miroir rotatif qui dévie l'impulsion lumineuse émise dans différentes positions angulaires, ce qui permet d'obtenir au moins un plan de balayage.The beam travel time can be used to calculate the distance between the object and the scanner 2 and thus calculate the distance between the object and the gate 1, 1a automatic outside. A scanner 2 may advantageously be able to scan a predefined surface by means of a rotating mirror which deflects the light pulse emitted in different angular positions, which makes it possible to obtain at least one scanning plane.

Un tel miroir peut aussi avoir plusieurs faces légèrement inclinées les unes par rapport aux autres, ce qui permet également de couvrir non plus seulement un unique plan bidimensionnel, mais plusieurs plans légèrement inclinés les uns par rapport aux autres.Such a mirror may also have several faces slightly inclined relative to each other, which also allows to cover not only a single two-dimensional plane, but several slightly inclined planes relative to each other.

Par exemple aux figures 1 à 4, pour chaque scanner 2, il est illustré quatre plans de balayage 8 qui définissent entre eux trois zones de détection 9 différentes. Ceci n'est cependant pas limitatif et il peut y avoir plus ou moins de trois zones de détection 9 pour chaque scanner 2.For example, Figures 1 to 4 for each scanner 2, there are illustrated four scanning planes 8 which define between them three different detection zones 9. This is however not limiting and there may be more or less than three detection zones 9 for each scanner 2.

Le plan de balayage 8 qui se trouve le plus proche du portail 1, 1a, par exemple d'un battant 3 du portail à battant 1 ou du panneau 3a du portail coulissant 1a peut avoir une vitesse de balayage plus élevée que le plan de balayage se trouvant le plus éloigné du portail 1, 1a et/ou une fréquence de balayage plus élevée.The scanning plane 8 which is closest to the gate 1, 1a, for example a leaf 3 of the leaf gate 1 or the panel 3a of the sliding gate 1a can have a higher scanning speed than the scanning plane. being farthest from gate 1, 1a and / or a higher scan frequency.

En effet, la zone de détection 9 la plus proche du portail 1, 1a est la plus propice à des collisions du portail 1, 1a avec un ou des objets. Les détections d'objets dans cette zone sont donc à effectuer le plus rapidement possible. Ceci est aussi valable pour des zones dites de haute sécurisation 16, 18 qui seront ultérieurement décrites.Indeed, the detection zone 9 closest to the portal 1, 1a is most conducive to collisions of the portal 1, 1a with one or objects. Detections of objects in this area should be done as quickly as possible. This is also valid for so-called high security zones 16, 18 which will be described later.

D'une manière générale, il peut y avoir une vitesse croissante de balayage dans les zones de détection 9 plus elles se rapprochent du portail 1, 1a automatique. Les plans de balayage 8 d'un même scanner 2 sont concourants au scanner 2 en divergeant du scanner 2 d'un angle compris de quelques degrés à 30°, comme il est visible aux figures 1a et 3a.In general, there may be an increasing scanning speed in the detection zones 9 as they move closer to the automatic gate 1, 1a. The scanning planes 8 of the same scanner 2 are concurrent with the scanner 2 diverging from the scanner 2 by an angle of a few degrees at 30 °, as can be seen in FIG. figures 1a and 3a .

D'une manière générale, pour chaque scanner 2, la détection d'un objet dans la zone la plus proche du portail 1, 1a (ou d'une autre zone) est transmise au microprocesseur du ou de chaque scanner 2 qui peut être connecté à la commande de l'ouverture ou de la fermeture du portail 1, 1a afin de pouvoir inverser le mouvement du portail 1, 1a si la présence d'au moins un objet est détecté au voisinage du portail 1, 1a. Plusieurs degrés de risque de coincement ou de collision du portail 1, 1a peuvent être prédéterminés qui impliquent des mouvements différents du portail 1, 1a en réaction à la présence dudit au moins un objet. Ceci sera ultérieurement plus précisément décrit. Un scanner peut offrir plusieurs zones de détection, dans des plans différents comme indiqué précédemment, mais aussi dans un même plan, par exemple à différents niveaux de la largeur du passage défini par le mouvement de la ou les portions mobiles. Dans tous ces cas, on peut générer des commandes différenciées en cas de détection, tel qu'un arrêt complet pour une zone, arrêt et inversion de mouvement dans une autre zone...In general, for each scanner 2, the detection of an object in the zone closest to the gate 1, 1a (or another zone) is transmitted to the microprocessor of the or each scanner 2 which can be connected when ordering the opening or closing of the gate 1, 1a in order to be able to reversing the movement of the portal 1, 1a if the presence of at least one object is detected in the vicinity of the portal 1, 1a. Several degrees of risk of jamming or collision of the portal 1, 1a may be predetermined which involve different movements of the portal 1, 1a in response to the presence of said at least one object. This will be more precisely described later. A scanner can offer several detection zones, in different planes as indicated above, but also in the same plane, for example at different levels of the width of the passage defined by the movement of the mobile portion or portions. In all these cases, it is possible to generate differentiated commands in the event of detection, such as a complete stop for one zone, stop and reversal of movement in another zone ...

Dans une forme de réalisation possible de la présente invention, il peut être prévu au moins un plan de balayage formant un angle plus élevé avec les autres plans de balayage, donc en étant espacé des autres plans de balayage 8. Ledit au moins un plan de balayage espacé des autres plans de balayage 8 ne sert pas à la sécurisation du portail 1, 1a contre la collision avec un objet, 1a mais à l'ouverture du portail 1, 1a quand un objet s'en approche, par exemple un véhicule, le véhicule étant assez loin du portail 1, 1a pour qu'il n'y ait pas de risque de collision entre lui et le portail 1, 1a.In one possible embodiment of the present invention, at least one scanning plane may be provided at a higher angle with the other scanning planes, thus being spaced from the other scanning planes 8. Said at least one plane of scanning spaced from the other scanning planes 8 is not used to secure the gate 1, 1a against the collision with an object, 1a but at the opening of the gate 1, 1a when an object approaches, for example a vehicle, the vehicle being far enough from the gate 1, 1a so that there is no risk of collision between him and the gate 1, 1a.

Le microprocesseur d'un ou des scanners 2 est avantageusement programmé pour agir sur les moyens d'entraînement du portail 1, 1a afin d'ouvrir le portail quand la présence d'un objet en aval ou en amont du portail est détectée dans ce plan de balayage espacé des autres pour la commande d'ouverture. Ceci peut aussi être appliqué pour la fermeture du portail quand la présence de l'objet est détectée de l'autre côté amont ou aval du portail.The microprocessor of one or more scanners 2 is advantageously programmed to act on the drive means of the portal 1, 1a in order to open the portal when the presence of an object downstream or upstream of the portal is detected in this plane. Scanning spaced from others for opening command. This can also be applied for closing the gate when the presence of the object is detected on the other side upstream or downstream of the portal.

Un scanner 2 en tant que moyens de détection présente une grande précision de mesure de distance et de détection d'objets tout en étant aisément adaptable à diverses conditions de travail qui lui sont imposées.A scanner 2 as detection means has a high accuracy of distance measurement and object detection while being easily adaptable to various working conditions imposed on it.

En se référant aux figures 1 et 2, pour un portail à battant 1, à son ouverture, le risque de collision du portail 1 avec un objet réside dans le fait que le ou les battants 3 font saillie à l'intérieur ou à l'extérieur de l'espace que ferme ou ouvre le portail 1, le plus fréquemment à l'intérieur de cet espace. De même, à la fermeture du portail 1, le risque de collision avec un objet peut se faire entre la position dans laquelle le ou les battants 3 font saillie à l'intérieur ou à l'extérieur de l'espace et la position dans laquelle le ou les battants sont en position de fermeture. Il convient de sécuriser le risque de collision pour chaque battant 3 du portail 1.Referring to Figures 1 and 2 , for a swing gate 1, at its opening, the risk of collision of the gate 1 with an object lies in the fact that or the leaves 3 protrude inside or outside the space that closes or opens portal 1, most frequently inside this space. Likewise, when gate 1 is closed, the risk of collision with an object can be between the position in which the wing (s) 3 protrude inside or outside the space and the position in which the door (s) are in the closed position. It is necessary to secure the risk of collision for each wing 3 of the gate 1.

Pour un portail à battant 1, il est donc prévu sur le bord supérieur de chaque battant 3 à proximité du poteau 4 fixe associé une paire de scanners 2, un scanner se trouvant à l'intérieur de l'espace fermé par le portail 1 et l'autre scanner se trouvant à l'extérieur de l'espace fermé. Il y a donc quatre scanners 2 pour un portail à deux battants, tous les scanners 2 étant avantageusement mobiles avec le portail 1 en étant placés par paires à la partie supérieure de chaque battant 3 et en se trouvant avantageusement près du poteau 4 fixe associé au battant 3.For a swing gate 1, it is therefore provided on the upper edge of each leaf 3 near the fixed post 4 associated a pair of scanners 2, a scanner located inside the space closed by the gate 1 and the other scanner is outside the closed space. There are therefore four scanners 2 for a gate with two leaves, all the scanners 2 being advantageously mobile with the gate 1 being placed in pairs at the upper part of each leaf 3 and advantageously located near the fixed post 4 associated with the flying 3.

L'avantage principal d'un tel positionnement des scanners 2 par paires sur chaque battant 3 du portail 1 à battants est qu'ils suivent le mouvement du ou des battants 3 du portail 1. Les plans de balayage 8 suivent donc le mouvement du portail à battant 1 et les zones de protection 9 qu'ils définissent sont toujours au plus près du portail 1. Il est ainsi obtenu une sécurisation parfaite contre des collisions, ceci pour les deux faces intérieure et extérieure du portail 1.The main advantage of such positioning of the scanners 2 in pairs on each leaf 3 of the gate 1 casement is that they follow the movement of the leaf or doors 3 of the gate 1. The scanning planes 8 therefore follow the movement of the gate 1 and the protection zones 9 that they define are always closer to the gate 1. It is thus obtained perfect security against collisions, this for both inner and outer faces of the gate 1.

Lors de l'ouverture du portail à battant 1, ce sont les scanners 2 placés du côté pour lequel le ou les battants 3 font saillie qui sont les plus susceptibles de détecter des risques de collision. Lors de cette ouverture, il peut être prévu des moyens de commande associés au microprocesseur d'au moins un scanner 2 se trouvant du côté du portail 1 vers lequel pointent le ou les battants 3 qui procèdent à l'inversion du sens de fonctionnement des moyens d'entraînement automatique effectuant l'actionnement du ou des battants 3. Le cas échéant, cette inversion est suivie de l'arrêt total du mouvement du portail 1.When opening the swing gate 1, it is the scanners 2 placed on the side for which the wing (s) 3 protrude are most likely to detect the risk of collision. During this opening, there may be provided control means associated with the microprocessor of at least one scanner 2 located on the side of the gate 1 to which point or the leaves 3 which perform the reversal of the direction of operation of the means automatic drive effecting the actuation of the wing (s) 3. If necessary, this reversal is followed by a complete stop of the movement of the gate 1.

Inversement, lors de la fermeture du portail à battant 1, ce sont les scanners 2 placés de l'autre côté du portail à battant 1 que celui pour lequel le ou les battants 3 font saillie qui sont les plus propices pour prévenir les risques de collision. Lors de cette fermeture, les moyens de commande associés au microprocesseur d'au moins un scanner 2 se trouvant de cet autre côté du portail 1 procèdent à l'inversion du sens de fonctionnement des moyens d'entraînement effectuant l'actionnement du ou des battants 3. Le cas échéant, cette inversion est suivie par l'arrêt total du mouvement du portail 1.Conversely, when closing the swing gate 1, it is the scanners 2 placed on the other side of the swing gate 1 that the one or the leaves 3 protruding are most conducive to prevent the risk of collision . During this closure, the control means associated with the microprocessor of at least one scanner 2 located on this other side of the gate 1 reverses the direction of operation of the drive means effecting the actuation of the leaf or leaves 3. If necessary, this reversal is followed by the total stop of the movement of the gate 1.

On peut ainsi définir une zone 17 pour chaque battant 3 qui est une zone de sécurisation à la fermeture avec inversion complète du mouvement du portail 1 et une zone 16 pour chaque battant 3 qui est une zone de sécurisation à l'ouverture avec inversion complète du mouvement du portail 1 et arrêt du portail, la zone 16 étant une zone de plus haute sécurisation que la zone de sécurisation 17.It is thus possible to define an area 17 for each leaf 3 which is a closing safety zone with complete reversal of the movement of the gate 1 and an area 16 for each leaf 3 which is an opening security area with complete inversion of the movement of the gate 1 and gate stop, the zone 16 being a zone of higher security than the security zone 17.

Il est possible de décomposer ces zones de protection 16 et 17 en sous zones avec un balayage renforcé ou avec des instructions différentes transmises aux moyens de commande du portail 1. Par exemple, sans que cela soit limitatif, lors de l'ouverture du portail 1, il peut être défini une sous-zone au voisinage de l'extrémité de chaque battant 3 pointant vers l'intérieur ou l'extérieur de l'espace fermé par le portail 1 à l'ouverture.It is possible to break down these protection zones 16 and 17 into sub-zones with a reinforced scan or with different instructions transmitted to the control means of the gate 1. For example, without this being limiting, when the gate 1 is opened , it can be defined a sub-area in the vicinity of the end of each leaf 3 pointing to the inside or outside of the space closed by the gate 1 at the opening.

En se référant aux figures 3 et 4, pour un portail coulissant 1a à son ouverture ou à sa fermeture, le risque de collision du portail 1a avec un objet n'est plus devant ou derrière le plan de fermeture du portail 1a, donc à l'intérieur ou à l'extérieur de l'espace pouvant être fermé par le portail 1a.Referring to Figures 3 and 4 for a sliding gate 1a when it opens or closes, the risk of collision of the gate 1a with an object is no longer in front of or behind the closure plane of the gate 1a, therefore inside or outside of the space that can be closed by the gate 1a.

Pour un tel portail coulissant 1a, le risque de collision se trouve dans le plan du portail coulissant 1a entre un bord latéral du portail coulissant 1a et un des poteaux 4a, 4b en tant que montants fixes. Ce poteau est, par exemple à l'ouverture du portail coulissant 1a, le premier poteau 4a fixe traversé par l'avant du portail 1a ou par rapport auquel l'avant du portail 1a coulisse transversalement. Au voisinage de ce premier poteau 4a, il existe des risques de coincement du portail 1a par rapport à ce premier poteau 4a fixe en plus des risques de collision avec un objet différent du portail 1a.For such a sliding gate 1a, the risk of collision lies in the plane of the sliding gate 1a between a lateral edge of the sliding gate 1a and one of the posts 4a, 4b as fixed amounts. This post is, for example at the opening of the sliding gate 1a, the first fixed post 4a traversed by the front of the gate 1a or relative to which the front of the gate 1a slides transversely. In the vicinity of the first post 4a, there is a risk of jamming of the portal 1a relative to the first fixed post 4a in addition to the risk of collision with an object different from the portal 1a.

A la fermeture du portail coulissant 1a, un tel risque de coincement du portail coulissant 1a avec le premier poteau 4a fixe existe toujours tandis qu'il peut exister aussi des risques de collision avec au moins un objet se trouvant entre le second poteau 4b contre lequel se dirige l'extrémité arrière latérale du portail 1a en butant contre ce second poteau 4b lors de la fermeture complète du portail 1a.At the closing of the sliding gate 1a, such a risk of jamming of the sliding gate 1a with the first fixed post 4a still exists while there may also be risk of collision with at least one object located between the second post 4b against which is directed to the rear lateral end of the gate 1a abutting against the second pole 4b during the complete closure of the gate 1a.

Dans le cas d'un tel portail coulissant, le risque de collision est avantageusement sécurisé par quatre scanners 2 portés par au moins un des poteaux 4a, 4b fixes, avantageusement le premier poteau 4a fixe traversé par le portail coulissant 1a, ces scanners 2 étant disposés en partie haute du premier poteau fixe 4a.In the case of such a sliding gate, the risk of collision is advantageously secured by four scanners 2 carried by at least one of the fixed posts 4a, 4b, advantageously the first stationary post 4a traversed by the sliding gate 1a, these scanners 2 being disposed in the upper part of the first fixed pole 4a.

En alternative, il est aussi possible de munir le second poteau 4b fixe, avantageusement le second poteau 4b fixe non traversé par le portail coulissant 1a et qui sert de butée de fin de course de fermeture du portail coulissant d'au moins deux scanners. Il est aussi possible de prévoir deux scanners 2 sur un premier poteau 4a et deux autres scanners 2 sur l'autre second poteau 4b.Alternatively, it is also possible to provide the second fixed post 4b, advantageously the second fixed post 4b not traversed by the sliding gate 1a and which serves as limit stop closing the sliding gate of at least two scanners. It is also possible to provide two scanners 2 on a first post 4a and two other scanners 2 on the other second post 4b.

Pour un groupe de quatre scanners 2 portés par le premier poteau 4a fixe servant au coulissement du panneau 3a du portail coulissant 1a lors de son ouverture, deux scanners 2 sont disposés de chaque côté intérieur et extérieur du portail coulissant 1a, l'objet susceptible d'entrer en collision avec le portail 1a pouvant provenir de l'intérieur ou de l'extérieur de l'espace que peut fermer le portail 1a.For a group of four scanners 2 carried by the first stationary post 4a for sliding the panel 3a of the sliding gate 1a when it is opened, two scanners 2 are arranged on each inner and outer side of the sliding gate 1a, the object capable of colliding with the portal 1a may come from inside or outside the space that can close the gate 1a.

De chaque côté intérieur ou extérieur du portail coulissant 1a, un scanner 2 est disposé du côté du mur que longe le portail 1a en balayant au moins une zone de détection affleurant le mur et l'autre scanner 2 est disposé en faisant face à l'autre second poteau 4b fixe, ladite au moins une zone de détection longeant la partie du panneau 3a du portail 1a n'ayant pas encore été coulissée le long du mur.On each inner or outer side of the sliding gate 1a, a scanner 2 is arranged on the side of the wall that runs along the gate 1a by scanning at least one detection zone flush with the wall and the other scanner 2 is arranged facing the another second fixed post 4b, said at least one detection zone along the portion of the panel 3a of the gate 1a has not yet been slid along the wall.

Comme précédemment mentionné, il est aussi possible de munir l'autre panneau 4b fixe d'au moins deux scanners, chacun étant disposé respectivement sur un côté intérieur ou extérieur du portail coulissant 1a et balayant au moins une zone de détection longeant respectivement intérieurement ou extérieurement le panneau 3a du portail 1a.As previously mentioned, it is also possible to provide the other fixed panel 4b of at least two scanners, each being respectively disposed on an inner or outer side of the sliding gate 1a and scanning at least one detection zone respectively running internally or externally. the panel 3a of the gate 1a.

Ceci peut être fait en complément ou en remplacement des deux scanners 2 portés par le premier poteau 4a fixe et balayant la portion respectivement interne et externe du panneau 3a du portail n'ayant pas été coulissé le long du mur. Comme le portail coulissant ne longe pas le mur le long du second poteau 4b fixe, des scanners balayant le mur adjacent au second poteau 4b fixe ne sont pas nécessaires. Des scanners 2 portés par le second poteau 4b fixe peuvent être avantageux lors de la fermeture du portail coulissant 1a.This can be done in addition to or instead of the two scanners 2 carried by the first fixed post 4a and sweeping the respective inner and outer portion of the panel 3a of the gate has not been slid along the wall. As the sliding gate does not run along the wall along the second fixed post 4b, scanners scanning the wall adjacent to the second fixed post 4b are not necessary. Scanners 2 worn by the second 4b fixed post may be advantageous when closing the sliding gate 1a.

Dans le cas d'un portail coulissant 1a, en plus du risque de collision avec au moins un objet se trouvant dans le plan du portail, ceci notamment lors de sa fermeture, il existe aussi un risque de coincement entre le portail 1a et le premier poteau 4a fixe par lequel pénètre ou contre lequel coulisse le panneau 3a du portail 1a lors de son ouverture. Pour tenir compte des risques de collision, il est défini des zones de sécurisation 17 s'étendant le long du panneau 3a du portail 1 a respectivement à l'intérieur et à l'extérieur de l'espace fermé par le portail 1a.In the case of a sliding gate 1a, in addition to the risk of collision with at least one object in the plane of the gate, this in particular when it closes, there is also a risk of jamming between the gate 1a and the first fixed post 4a through which penetrates or against which slides the panel 3a of the gate 1a when it opens. To take into account the risk of collision, there are defined securing zones 17 extending along the panel 3a of the gate 1 a respectively inside and outside the closed space by the gate 1a.

Pour tenir compte des risques de coincement, il est aussi défini des zones de haute sécurisation 16 s'étendant à proximité du premier poteau 4a par lequel pénètre ou contre lequel coulisse le panneau 3a du portail 1a et se trouvant près du premier poteau 4a sur son côté faisant face au second poteau 4b. De l'autre côté du premier poteau 4a tourné vers le mur contre lequel coulisse le portail 1a lors de son ouverture, il est défini des zones de haute sécurisation 18 au voisinage du premier poteau 4a en étant symétriques aux zones de haute sécurisation 16 précédemment mentionnées et donc ayant sensiblement les mêmes dimensions.To take account of the risk of jamming, it is also defined zones of high security 16 extending near the first pole 4a through which penetrates or against which slides the panel 3a of the gate 1a and located near the first pole 4a on its side facing the second post 4b. On the other side of the first post 4a turned towards the wall against which the gate 1a slides when it is opened, high security zones 18 are defined in the vicinity of the first post 4a while being symmetrical to the high security zones 16 previously mentioned. and therefore having substantially the same dimensions.

Ensuite le long du mur, il est défini des zones de sécurisation 19 de chaque côté de la portion du panneau 3a du portail 1a rentrée le long du mur. Dans ces zones de sécurisation 19, le risque de coincement est relativement faible tandis que le risque de collision persiste.Then along the wall, there are defined securing zones 19 on each side of the portion of the panel 3a of the portal 1a retracted along the wall. In these areas of security 19, the risk of jamming is relatively low while the risk of collision persists.

Ainsi dans tous les modes de réalisation de l'invention, le procédé de détection d'au moins un objet dans la zone de déplacement en ouverture ou en fermeture d'au moins une portion mobile 3, 3a d'un portail 1, 1a automatique prévoit que ledit au moins un plan de balayage 8 longeant au moins partiellement la zone de déplacement de ladite au moins une portion mobile 3, 3a comprend au moins une zone de haute sécurisation 16, 18 dans laquelle, éventuellement, la vitesse et/ou la fréquence du balayage est plus grande que la vitesse et/ou la fréquence dans le reste 17, 19 du plan de balayage 8.Thus, in all the embodiments of the invention, the method for detecting at least one object in the zone of displacement when opening or closing at least one movable portion 3, 3a of an automatic portal 1, 1a provides that said at least one scanning plane 8 at least partially along the displacement zone of said at least one movable portion 3, 3a comprises at least one high security zone 16, 18 in which, possibly, the speed and / or the the scanning frequency is greater than the speed and / or the frequency in the remainder 17, 19 of the scanning plane 8.

Une telle zone de haute sécurisation 16, 18 est prédéterminée comme étant une zone où les risques de collision ou de coincement du portail 1, 1a sont les plus élevés, par exemple la zone au voisinage du montant fixe 4a par lequel pénètre ou coulisse transversalement le panneau 3a du portail coulissant 1a. Il peut exister plus que deux degrés de zones de sécurisation 16 à 19. Un intérêt de différencier les zones est d pouvoir appliquer des commandes différentes selon le cas.Such a high security zone 16, 18 is predetermined as being an area where the risks of collision or jamming of the portal 1, 1a are the highest, for example the area in the vicinity of the fixed amount 4a through which penetrates or slides transversely the panel 3a of the sliding gate 1a. There can be more than two degrees of security zones 16 to 19. An advantage of differentiating the zones is to be able to apply different commands as the case may be.

Du fait de la connexion du microprocesseur des scanners 2 avec les moyens de commande des moyens d'entraînement du portail 1, 1a, quand un risque de collision ou de coincement dans la zone de haute sécurisation 16 lors de l'ouverture ou de la fermeture du portail 1a est détecté, notamment à l'ouverture, il est procédé à l'inversion sur une course donnée, par exemple 15 cm, du mouvement du portail 1a et à l'arrêt du portail 1a.Due to the connection of the microprocessor of the scanners 2 with the control means of the drive means of the gate 1, 1a, when a risk of collision or jamming in the high-security zone 16 when opening or closing of the gate 1a is detected, especially at the opening, it is proceeded to the inversion on a given stroke, for example 15 cm, the movement of the gate 1a and the gate 1a stop.

Quand un risque de collision ou de coincement dans la zone de haute sécurisation 18 lors de l'ouverture ou de la fermeture du portail 1a est détecté, notamment à la fermeture, il est procédé à l'inversion complète du mouvement du portail 1a.When a risk of collision or jamming in the high-security zone 18 during the opening or closing of the gate 1a is detected, in particular at closing, it is proceeded to the complete reversal of the movement of the gate 1a.

Quand un risque de collision dans la zone de sécurisation 17 lors de l'ouverture ou de la fermeture du portail 1a est détecté, notamment à la fermeture, il est procédé à l'inversion complète du mouvement du portail 1a.When a risk of collision in the securing zone 17 when the gate 1a is opened or closed is detected, in particular at closing, the movement of the gate 1a is completely reversed.

Quand un risque de collision dans la zone de sécurisation 19 lors de l'ouverture ou de la fermeture du portail 1a est détecté, notamment à l'ouverture, il est procédé à l'inversion complète du mouvement du portail 1a et à l'arrêt du portail 1a.When a risk of collision in the security zone 19 when opening or closing the gate 1a is detected, especially at the opening, it is proceeded to the complete reversal of the movement of the gate 1a and stopped Portal 1a.

Ainsi, la commande du mouvement d'ouverture ou de fermeture de ladite au moins une portion mobile 3, 3a du portail 1, 1a est modifiée de manière différente selon que la détection d'au moins un objet se trouvant dans la zone de déplacement de ladite au moins une portion mobile 3, 3a du portail 1, 1a se fait dans une zone de haute sécurisation 16, 18 ou dans le reste 17, 19 du plan de balayage 8.Thus, the control of the opening or closing movement of said at least one movable portion 3, 3a of the gate 1, 1a is modified in a different manner depending on whether the detection of at least one object in the movement zone of said at least one movable portion 3, 3a of the gate 1, 1a is in a high-security zone 16, 18 or in the remainder 17, 19 of the scanning plane 8.

On peut donc différencier la sécurisation en appliquant des commandes différentes suivant le lieu de la détection ; les zones de détection peuvent être facilement prédéfinies lors de l'installation par exemple en fonction de la situation de fonctionnement du portail. Les zones de sécurisation peuvent se suivre suivant la dimension en largeur du passage et/ou des portions mobiles. Elles peuvent être de profil rectangulaire ou non. Leur contour peut donc être adapté à la situation.It is therefore possible to differentiate security by applying different commands depending on the location of the detection; the detection zones can be easily predefined during the installation, for example according to the operating situation of the portal. The securing zones can be followed according to the width dimension of the passage and / or movable portions. They can be of rectangular profile or not. Their outline can therefore be adapted to the situation.

Dans un mode de réalisation, particulièrement applicable aux portails coulissants, le ou les scanners sont portés par un montant ou portique rapporté à une installation préexistante. Dans ce cadre, l'invention s'adresse aussi à la modification de portails déjà installés, par l'ajout d'une partie de sécurisation caractéristique de l'invention.In one embodiment, particularly applicable to sliding gates, the scanner or scanners are carried by an amount or gantry reported to a pre-existing installation. In this context, the invention is also directed to the modification of already installed gates, by the addition of a characteristic security part of the invention.

On notera que l'invention assure préférentiellement une sécurisation de l'intégralité du portail si bien qu'aucune zone n'est laissée sans surveillance. De ce fait, il n'est pas nécessaire d'avoir recours à d'autres sécurités telles que des limitations de couples moteur. On peut ainsi employer les mêmes paramètres moteur pour toutes les installations, ce qui était jusqu'ici impossible, notamment selon les zones de classification au vent.It will be noted that the invention preferably ensures a security of the entire portal so that no area is left unattended. Therefore, it is not necessary to resort to other securities such as torque limitations. It is thus possible to use the same engine parameters for all the installations, which hitherto was impossible, in particular according to the wind classification zones.

L'invention n'est nullement limitée aux modes de réalisation décrits et illustrés qui n'ont été donnés qu'à titre d'exemples.The invention is in no way limited to the described and illustrated embodiments which have been given by way of example only.
