Description

La présente invention concerne le domaine des systèmes de contrôle d'accès et plus particulièrement des sas de sécurité permettant le contrôle et la régulation des passages de personnes entre deux espaces et a pour objet un dispositif de sas de sécurité.The present invention relates to the field of access control systems and more particularly security locks for controlling and regulating the passage of people between two spaces and relates to a safety lock device.

On sait qu'un sas de sécurité, qui forme une chambre, généralement de petites dimensions, munie de deux portes, permet uniquement le passage d'une seule personne autorisée, parfois plusieurs personnes autorisées, à la fois, d'un premier espace dans un second espace et réciproquement.It is known that a security chamber, which forms a room, generally of small size, provided with two doors, allows only the passage of a single authorized person, sometimes several authorized persons, at a time, a first space in a second space and vice versa.

Les deux portes d'un tel sas de sécurité ne sont jamais ouvertes en même temps, sauf lors d'une utilisation en situation d'urgence ou exceptionnelle, par exemple lors d'une évacuation en cas d'incendie ou lorsque des objets encombrants doivent transiter d'un espace à l'autre. Plus particulièrement, seule la porte devant laquelle se présente la personne autorisée est ouverte dans un premier temps, puis, l'autre porte est ouverte uniquement lorsque la personne est présente dans la chambre et que la première porte est complètement refermée et verrouillée.The two doors of such a security chamber are never opened at the same time, except when used in an emergency or exceptional situation, for example during an evacuation in case of fire or when bulky objects must transit from one space to another. More specifically, only the door in front of which the authorized person is presented is opened at first, then, the other door is opened only when the person is present in the room and the first door is completely closed and locked.

Par la suite, la porte permettant à la personne autorisée d'entrer dans la chambre du sas sera dénommée porte d'entrée et l'autre porte permettant à ladite personne de sortir de la chambre sera dénommée porte de sortie.Subsequently, the door allowing the authorized person to enter the room of the lock will be called the door and the other door allowing the person to leave the room will be called exit door.

Ainsi, lorsque plusieurs personnes doivent traverser consécutivement le sas, le temps avant que la personne suivante puisse utiliser le sas dans la même direction est égal à la somme des temps d'ouverture et de fermeture de la porte d'entrée, puis de la porte de sortie et ce n'est que lorsque la porte de sortie est fermée et verrouillée que la porte d'entrée peut à nouveau s'ouvrir ou être libérée en ouverture pour autoriser le passage suivant dans la même direction.Thus, when several people have to cross the airlock consecutively, the time before the next person can use the airlock in the same direction is equal to the sum of the opening and closing times of the entry door, then the door It is only when the exit door is closed and locked that the entrance door can open again or be released in opening to allow the next passage in the same direction.

Toutefois, si les sas actuels présentent une bonne ergonomie, une facilité d'utilisation et une rapidité des mouvements, ces sas étant automatiques, au moins en fermeture, grâce à des systèmes connus sous le nom usuel de ferme portes, un certain nombre de dispositions doivent être prévues pour éviter toute blessure de l'utilisateur, notamment lors de la phase de fermeture des vantaux ou battants.However, if the current airlock have good ergonomics, ease of use and speed of movement, these airlock being automatic, at least closing, through systems known under the usual name of firm doors, a number of provisions must be provided to avoid any injury to the user, especially during the closing phase of leaves or wings.

Pour limiter les risques de blessures, il a été proposé de ralentir les mouvements de fermeture des vantaux et plus particulièrement la fin du mouvement ou de la phase de fermeture.To limit the risk of injury, it has been proposed to slow closing movements of the leaves and more particularly the end of the movement or the closing phase.

Cependant, cette solution allonge d'autant le temps du cycle de l'ouverture/fermeture d'une porte du sas puis de l'autre porte.However, this solution extends all the time of the cycle of the opening / closing of a door of the airlock and the other door.

Pour remédier à cet inconvénient, il a été proposé de relier mécaniquement la cinématique d'entraînement, c'est à dire les ferme portes respectifs, des vantaux des deux portes afin de commencer à ouvrir la porte de sortie seulement lorsque la porte d'entrée, en phase ou en cours de fermeture, n'est pas encore totalement fermée c'est-à-dire que la porte d'entrée est dans une position entrouverte ou d'entrebâillement ne permettant pas le passage et l'entrée dans la chambre du sas.To remedy this drawback, it has been proposed to mechanically connect the drive kinematics, ie the respective doors, doors of the two doors to start to open the exit door only when the entrance door , in phase or in the course of closing, is not yet completely closed, that is to say that the entrance door is in an open position or crack opening not allowing passage and entry into the room of the airlock.

Le document EP 0 643 790 B1 décrit un tel sas d'entrée pour personnes habilitées comprenant un premier et un second systèmes de portes, dont chacun est équipé avec au moins un vantail de porte, lesdits systèmes étant espacés et définissant une chambre entre eux et comprenant en outre des mécanismes de verrouillage commandés électriquement ou électroniquement pour les deux systèmes de portes, qui sont déverrouillés de manière commandée lorsque les critères prédéterminés sont remplis pour permettre l'actionnement des systèmes de portes, et un mécanisme d'accouplement mécanique entre les deux systèmes de portes qui, lors d'un actionnement de l'un des deux systèmes de portes ou premier système, cause l'actionnement forcé de l'autre système de porte ou second système déjà durant la fermeture du premier système. Le degré d'ouverture pour laisser passer une personne par le second système est atteint seulement lorsque le degré d'ouverture du premier système a diminué de manière telle qu'un passage d'une personne ne soit plus possible.The document EP 0 643 790 B1 discloses such an entry lock for authorized persons comprising first and second door systems, each of which is equipped with at least one door leaf, said systems being spaced apart and defining a chamber therebetween and further comprising locking mechanisms electrically or electronically controlled for the two door systems, which are unlocked in a controlled manner when the predetermined criteria are met to enable actuation of the door systems, and a mechanical coupling mechanism between the two door systems which, when actuation of one of the two door systems or the first system causes the forced actuation of the other door system or second system already during the closing of the first system. The degree of opening to let a person through the second system is reached only when the degree of opening of the first system has decreased so that a passage of a person is no longer possible.

Cependant, ce type de sas avec mécanisme d'accouplement présente au moins les trois inconvénients suivants :

  • la liaison mécanique entre les deux portes dépendantes mécaniquement l'une de l'autre, dans leur fonctionnement d'ouverture et/ou de fermeture automatique(s), entraîne le fait que le réglage de la vitesse de fermeture ou d'ouverture de l'une des portes influe sur la vitesse de fermeture ou d'ouverture de l'autre porte,
  • l'ouverture de la seconde porte étant réalisée pendant la fin de du mouvement ou de la phase de fermeture de la première porte, donc sur une faible portion du mouvement de cette dernière, il est nécessaire de mettre en oeuvre une démultiplication qui transmet aussi les efforts avec des risques de pincement et d'écrasement des doigts de l'utilisateur qui ne peut repousser le ou les vantaux concernés,
  • la liaison mécanique fige la distance entre les deux portes, c'est-à-dire la profondeur du sas.
However, this type of lock with coupling mechanism has at least the following three disadvantages:
  • the mechanical connection between the two doors mechanically dependent on each other, in their automatic opening and / or closing operation (s), causes the setting of the closing or opening speed of the one of the doors affects the closing or opening speed of the other door,
  • the opening of the second door being performed during the end of the movement or the closing phase of the first door, so on a small portion of the movement of the latter, it is necessary to implement a reduction gear which also transmits the efforts with the risk of pinching and crushing fingers of the user who can not push the door or leaves concerned,
  • the mechanical link freezes the distance between the two doors, that is to say the depth of the lock.

Le document US2010011665 a pour objet un dispositif de contrôle d'accès du type sas de sécurité pour contrôler, à partir d'un sas de sécurité, les accès dans un immeuble, ledit dispositif comprenant deux panneaux de portes pivotantes fermant le sas et deux bras contrôlant chacun le mouvement de l'un des panneaux et étant capables de se déplacer le long du flux entrant ou sortant. Chaque panneau est connecté mécaniquement à l'un des bras au moyen d'un point de fixation formant un axe de pivotement vertical du panneau correspondant par rapport au bras. En outre, chaque point de fixation est monté dans le bras correspondant de sorte à pouvoir se déplacer, et ensemble le panneau solidaire dudit point, le long du bras latéralement au flux. Chaque panneau peut ainsi pivoter et être déplacé dans le sens du flux de passage d'avant en arrière.The document US2010011665 relates to an access control device of the security lock type for controlling, from a security lock, access to a building, said device comprising two pivoting door panels closing the lock and two arms each controlling the movement of one of the panels and being able to move along the inflow or outflow. Each panel is mechanically connected to one of the arms by means of an attachment point forming a vertical pivot axis of the corresponding panel relative to the arm. In addition, each attachment point is mounted in the corresponding arm so as to move, and together the integral panel of said point, along the arm laterally to the flow. Each panel can thus rotate and be moved in the direction of the flow of passage from front to back.

Toutefois, le dispositif du document US2010011665 nécessite comme d'autres sas actuels, une fermeture complète de la porte d'entrée avant de procéder à l'ouverture de la porte de sortie pour permettre à la personne présente dans le sas de sortir et pour empêcher une personne non autorisée de rentrer dans le sas en profitant d'une position entrouverte de la porte permettant encore le passage d'une personne. Ainsi, ce temps d'attente de la fermeture complète de la porte d'entrée augmente d'autant le temps de cycle d'ouverture/fermeture du sas et diminue d'autant la vitesse de passage. En outre, ce dispositif nécessite, au cours du passage d'une personne à travers le sas, une étape de déplacement faisant passer la porte de sortie derrière la porte d'entrée, la porte de sortie devenant alors, pour le cycle suivant, la porte d'entrée. D'autre part, du fait de la combinaison du mouvement de pivotement et de déplacement dans le sas du flux rendue possible pour chaque panneau de porte (vantail ou battant) un tel dispositif présente l'inconvénient de fonctionner de façon spécifique, c'est à dire d'une manière différente des sas classiques ce qui peut perturber les habitudes des personnes, voire les dissuader de rentrer dans le sas. Enfin ce fonctionnement et cette structure spécifiques du sas ne permet pas une utilisation avec des portes standards équipant les sas classiques, ce qui augmente d'autant les couts de fabrication et d'installation et ne permet pas une mise en oeuvre sur des sas existants.However, the document feature US2010011665 requires, like other existing airlock, a complete closure of the front door before opening the exit door to allow the person present in the airlock to exit and to prevent an unauthorized person from entering the airlock taking advantage of a half-open position of the door still allowing the passage of a person. Thus, this waiting time of the complete closure of the entrance door increases all the opening / closing cycle time of the airlock and decreases all the speed of passage. In addition, this device requires, during the passage of a person through the lock, a moving step passing the exit door behind the entrance door, the exit door then becoming, for the next cycle, the front door. On the other hand, because of the combination of the pivoting movement and movement in the flow lock made possible for each door panel (leaf or leaf) such a device has the disadvantage of operating specifically, it is to say in a different way from conventional airlock which can disrupt the habits of people, or even deter them from entering the airlock. Finally, this operation and this specific structure of the airlock does not allow use with standard doors equipping the conventional airlock, which increases the costs of manufacturing and installation and does not allow implementation on existing locks.

La présente invention a pour but de pallier ces inconvénients en proposant un dispositif de sas de sécurité permettant, d'une part, de diminuer le temps de cycle d'ouverture/fermeture du sas lors du passage d'une personne et donc d'augmenter la vitesse de passage, tout en conservant la fonctionnalité de base d'un sas de sécurité classique n'autorisant que le passage d'une seule personne ou d'un nombre limité de personnes à la fois et, d'autre part, l'ouverture de la porte de sortie avant que la porte d'entrée ne soit complètement fermée tout en empêchant le passage par ladite porte d'entrée.The present invention aims to overcome these disadvantages by providing a safety lock device for, on the one hand, to reduce the opening / closing cycle time of the airlock during the passage of a person and therefore increase the speed of passage, while maintaining the basic functionality of a conventional security lock that allows only one or a limited number of people to pass at one time and the opening of the front exit door that the entrance door is completely closed while preventing the passage through said front door.

A cet effet, la présente invention a pour objet un dispositif de sas de sécurité pour le contrôle et la régulation des flux de personnes entre deux espaces, ledit dispositif comprenant deux portes espacées et définissant entre elles une chambre, chaque porte comprenant un ou plusieurs vantaux et un système de fermeture et/ou d'ouverture comprenant des moyens mobiles pour le déplacement automatique du ou des vantaux de ladite porte en vue de réaliser sa fermeture automatique et/ou son ouverture automatique, lesdits systèmes d'ouverture et/ou de fermeture étant indépendants l'un par rapport à l'autre, ledit dispositif comprenant en outre au moins une unité de commande électronique et se caractérisant en ce qu'au moins l'une desdites portes est associée à :

  • des moyens de détection aptes à détecter, lors de la fermeture automatique de ladite porte associée, une position de fermeture ou une contrainte de réouverture prédéterminées de ladite porte associée et à envoyer un signal de détection représentatif de ladite position ou contrainte prédéterminées à la ou l'une desdites unités de commande électroniques,
  • un système anti-retour inaccessible apte à être commandé, par la ou l'une desdites unités de commande électronique suite à la réception et à la validation par cette dernière dudit signal de détection, dans un état de verrouillage ou de préverrouillage, le ou chaque système anti-retour comprenant au moins un organe de butée escamotable et des moyens d'actionnement permettant de déplacer ledit organe de butée depuis une position escamotée ou de déverrouillage jusqu'à une position de butée ou de verrouillage se trouvant sur la trajectoire d'au moins une partie de contact des moyens mobiles ou du ou des vantaux de la porte associée de sorte à empêcher, par contact de butée entre la au moins une partie de contact et le au moins un organe de butée, la réouverture de ladite porte associée lorsque celle-ci se trouve, lors de sa fermeture, dans une position entrouverte de sécurité ne permettant pas le passage et l'entrée dans la chambre.
To this end, the present invention relates to a safety lock device for controlling and regulating the flow of people between two spaces, said device comprising two doors spaced apart and defining between them a chamber, each door comprising one or more leaves and a closing and / or opening system comprising movable means for the automatic movement of the door leaf (s) to achieve its automatic closing and / or automatic opening, said opening and / or closing systems being independent of one another, said device further comprising at least one electronic control unit and characterized in that at least one of said gates is associated with:
  • detection means adapted to detect, upon automatic closure of said associated door, a predetermined closed position or reopening stress of said associated door and to send a detection signal representative of said predetermined position or constraint to the one of said electronic control units,

Les figures montrent un dispositif de sas de sécurité pour le contrôle et la régulation des flux de personnes entre deux espaces, ledit dispositif comprenant deux portes 1 et 2 espacées et définissant entre elles une chambre 3, chaque porte 1 ou 2 comprenant un ou plusieurs vantaux 4 ou 5 et un système de fermeture et/ou d'ouverture 6; 7, comprenant des moyens mobiles 6a, 6b, 6c ou 7a, 7b, 7c pour le déplacement automatique du ou des vantaux 4 ou 5 de ladite porte 1 ou 2 concernée en vue de réaliser la fermeture automatique et/ou l'ouverture automatique de ladite porte 1 ou 2 concernée.The figures show a safety lock device for controlling and regulating the flow of people between two spaces, said device comprising two doors 1 and 2 spaced apart and defining between them a chamber 3, each door 1 or 2 comprising one or more leaves 4 or 5 and a closing and / or opening system 6; 7, comprising movable means 6a, 6b, 6c or 7a, 7b, 7c for the automatic movement of the door leaf (s) 4 or 5 of said door 1 or 2 concerned with a view to automatic closing and / or automatic opening of said door 1 or 2 concerned.

Conformément à la présente invention, les deux systèmes d'ouverture et/ou de fermeture 6; 7 sont indépendants l'un par rapport à l'autre, c'est-à-dire qu'il n'existe aucun lien mécanique ou fonctionnel entre les deux systèmes d'ouverture et/ou de fermeture.According to the present invention, the two opening and / or closing systems 6; 7 are independent of each other, that is to say that there is no mechanical or functional link between the two systems of opening and / or closing.

Toujours conformément à la présente invention un tel dispositif comprend en outre au moins une unité de commande électronique, non représentée, et au moins l'une desdites portes 1 ou 2 est associée :

  • à des moyens de détection aptes à détecter, lors de la fermeture automatique de ladite porte 1 ou 2 associée, une position de fermeture ou une contrainte de réouverture prédéterminées de ladite porte associée 1 ou 2 et à envoyer un signal de détection représentatif de ladite position ou contrainte prédéterminées à la ou l'une desdites unités de commande électroniques.
Still according to the present invention such a device further comprises at least one electronic control unit, not shown, and at least one of said doors 1 or 2 is associated:
  • detection means able to detect, during the automatic closure of said associated door 1 or 2, a predetermined closed position or a reopening constraint of said associated door 1 or 2 and to send a detection signal representative of said position or predetermined constraint to the or one of said electronic control units.

En outre au moins l'une desdites portes 1 ou 2 associée auxdits moyens de détection est également associée à un système anti-retour 8 inaccessible et apte à être commandé, par la ou l'une desdites unités de commande électronique suite à la réception et à la validation par cette dernière dudit signal de détection, dans un état de verrouillage ou de préverrouillage de sorte à pouvoir coopérer par contact de butée, dans ledit état de verrouillage, avec au moins une partie de contact 6a ou 7a des moyens mobiles 6a, 6b, 6c ou 7a, 7b, 7c ou du ou des vantaux 4 ou 5 de la porte 1 ou 2 associée pour empêcher sa réouverture lorsque celle-ci se trouve, lors de sa fermeture, dans une position entrouverte de sécurité ne permettant pas le passage et l'entrée dans ladite chambre 3.In addition, at least one of said gates 1 or 2 associated with said detection means is also associated with an inaccessible and controllable anti-return system 8, by the one or more of said electronic control units following reception and the validation by the latter of said detection signal, in a state of locking or pre-locking so as to cooperate by abutment contact, in said locking state, with at least one contact portion 6a or 7a of the movable means 6a, 6b, 6c or 7a, 7b, 7c or the door leaf (s) 4 or 5 of the door 1 or 2 associated to prevent its reopening when it is, when it is closed, in an open security position not allowing the passage and entry into said chamber 3.

On entendra par système de fermeture et/ou d'ouverture un système permettant d'assurer la fermeture automatique et l'ouverture automatique de la porte 1 ou 2 correspondante, mais pouvant éventuellement être prévu pour assurer uniquement la fermeture automatique de ladite porte 1 ou 2.By closing and / or opening system will be meant a system for automatically closing and automatically opening the corresponding door 1 or 2, but possibly being able to provide only for the automatic closing of said door 1 or 2.

Les termes de fermeture ou d'ouverture de chaque porte 1 ou 2 doivent être compris, selon la présente invention, comme correspondant respectivement à un mouvement de fermeture ou d'ouverture de la porte 1 ou 2, c'est-à-dire un déplacement du ou de ses vantaux.The terms of closing or opening of each door 1 or 2 must be understood, according to the present invention, as corresponding respectively to a closing or opening movement of the door 1 or 2, that is to say a displacement of the or its leaves.

Bien entendu, ce qui n'est pas décrit dans la présente demande, chaque porte 1 ou 2 peut comprendre un système de verrouillage ou de blocage en fermeture tel qu'une serrure électrique permettant de bloquer ou de verrouiller chaque porte dans sa position de fermeture complète. De telles serrures électriques peuvent être commandées, selon la présente invention, par la ou les unités de commande électroniques.Of course, what is not described in the present application, each door 1 or 2 may include a locking or closing locking system such as an electric lock for locking or locking each door in its closed position complete. Such electric locks can be controlled, according to the present invention, by the electronic control unit or units.

D'autre part, la fin de la fermeture de chaque porte 1 ou 2, notamment dans la position entrouverte de sécurité, précédant donc sa fermeture complète, ou l'ouverture de chaque porte 1 ou 2 peut être ralentie pour assurer la sécurité des utilisateurs. Un tel ralentissement ou freinage de la fermeture ou de l'ouverture de la porte 1 ou 2 concernée peut être obtenue par un mécanisme de freinage qui peut être par exemple un mécanisme de freinage par contrôle électronique de la vitesse d'un moteur, voire un mécanisme de freinage hydraulique ou électro-hydraulique, que l'on peut trouver, par exemple, dans certains ferme-portes ou ouvre-portes actuels tels que, par exemple, les ferme-portes ou ouvre-portes commercialisés sous le nom « DORMA ED 200 » équipés de mécanismes électrohydrauliques.On the other hand, the end of the closing of each door 1 or 2, especially in the open security position, thus precedes its complete closure, or the opening of each door 1 or 2 can be slowed down to ensure the safety of users . Such slowing or braking of the closing or opening of the door 1 or 2 concerned can be obtained by a braking mechanism which can be for example a braking mechanism by electronic control of the speed of an engine, or even a hydraulic or electro-hydraulic braking mechanism, which can be found, for example, in certain existing door closers or door openers such as, for example, door closers or door openers marketed under the name "DORMA ED 200 "equipped with electrohydraulic mechanisms.

On entendra par système anti-retour 8 inaccessible le fait de positionner ce dernier de sorte qu'il soit hors d'atteinte des utilisateurs, par exemple, en étant entièrement positionné, de préférence, soit au-dessus du ou derrière le plafond 3a de la chambre 3 (figure 11), ce notamment dans le cas d'une porte pivotante, soit dans un capot de protection du type capot de protection d'un mécanisme d'entraînement usuel d'une porte coulissante.An inaccessible anti-return system 8 will be understood to mean positioning it so that it is out of reach of the users, for example, by being entirely positioned, preferably, either above or behind the ceiling 3a. the room 3 ( figure 11 ), in particular in the case of a pivoting door, or in a protective cover of the type of protective cover of a conventional drive mechanism of a sliding door.

L'état de verrouillage du ou de chaque système anti-retour 8 peut alors être activé systématiquement à chaque fermeture de la porte 1 ou 2 associée suite à la détection de ladite position prédéterminée, c'est-à-dire suite à la réception par l'unité de commande électronique concernée du signal de détection correspondant.In a first embodiment, the detection means may be able to detect a predetermined position of the door leaf (s) of said associated door 1 or 2 when it is in the open security position. The locking state of the or each non-return system 8 can then be activated systematically at each closing of the associated door 1 or 2 following the detection of said predetermined position, that is to say following reception by the relevant electronic control unit of the corresponding detection signal.

Dans une seconde forme de réalisation, les moyens de détection peuvent être aptes à détecter une contrainte de réouverture extérieure exercée sur le ou les vantaux 4 ou 5 de la porte 1 ou 2 associée et représentative d'une réouverture de la porte 1 ou 2 associée lorsque celle-ci se trouve dans la position entrouverte de sécurité. L'état de verrouillage du ou de chaque système anti-retour 8 peut alors être commandé uniquement suite à la détection de ladite contrainte, c'est-à-dire suite à la réception par l'unité de commande électronique concernée du signal de détection correspondant.In a second embodiment, the detection means may be able to detect an external reopening stress exerted on the leaf (s) 4 or 5 of the associated door 1 or 2 and representative of a reopening of the door 1 or 2 associated when it is in the open security position.

Si on se réfère maintenant à la figure 11 on peut voir que dans cette première forme de réalisation du dispositif, l'ensemble composé du système d'ouverture et/ou de fermeture 6 et du système anti-retour 8 est positionné ou s'étend au-dessus ou derrière le plafond 3a de la chambre 3, lequel plafond 3a comporte une ou plusieurs ouvertures 3b permettant le passage des bras, barres ou tringles 6b articulées, ce de manière à rendre inaccessible pour les usagers le système anti-retour 8.If we now refer to the figure 11 it can be seen that in this first embodiment of the device, the assembly consisting of the opening and / or closing system 6 and the anti-return system 8 is positioned or extends above or behind the ceiling 3a of the chamber 3, which ceiling 3a comprises one or more openings 3b allowing the passage of the arms, bars or rods 6b hinged, so as to make inaccessible to users the anti-return system 8.

Dans une seconde forme de réalisation du dispositif selon la présente invention, au moins l'une des deux portes 1 ou 2 peut être une porte coulissante comprenant au moins un vantail 5 coulissant, de préférence montée dans un cadre dormant 5a, et le système d'ouverture et/ou de fermeture 7 de ladite porte 1 ou 2 coulissante peut comprendre un moteur 7b apte à entraîner le ou lesdits vantaux 5 coulissants par l'intermédiaire d'une courroie 7c, ou autre élément de transmission fonctionnellement analogue, reliée au(x)dit(s) vantail(aux) 5 grâce à des pièces d'entraînement 7a, dont l'une au moins est apte à venir en contact de butée avec le ou les organes de butée 8a actionnés en position de butée (figure 10).In a second embodiment of the device according to the present invention, at least one of the two doors 1 or 2 may be a sliding door comprising at least one sliding leaf, preferably mounted in a fixed frame 5a, and the sliding system. opening and / or closing 7 of said sliding door 1 or 2 may comprise a motor 7b adapted to drive said sliding door (s) by means of a belt 7c, or other functionally similar transmission element, connected to the x) said leaf (s) 5 thanks to drive parts 7a, at least one of which is able to come into abutting contact with the abutment member or bodies 8a actuated in the stop position ( figure 10 ).

Bien entendu, dans ce second mode de réalisation, le système anti-retour 8 peut être disposé dans un capot de protection du type capot de protection usuel, non représenté, renfermant un mécanisme d'entraînement classique de porte coulissante, ce afin d'être rendu inaccessible.Of course, in this second embodiment, the anti-return system 8 can be arranged in a protective cover of the usual protective cover type, not shown, enclosing a conventional sliding door drive mechanism, so as to be rendered inaccessible.

De préférence, le ou chaque système anti-retour 8 peut comprendre un support 8d apte à supporter le ou plusieurs organes de butée 8a et des moyens de maintien et de libération 9. Le support 8d peut être débrayable de sorte à pouvoir être, grâce auxdits moyens de maintien et de libération 9, d'une part, maintenu fixement dans une position assurant le fonctionnement normal dudit système anti-retour 8 (figure 5) et, d'autre part, libéré afin de rendre possible, à l'état de verrouillage de ce dernier, le déplacement ou le basculement du support 8d sous l'effet d'une contrainte de poussée exercée sur le ou les organes de butée 8a en position de butée (figure 4). Ceci de sorte à effacer le ou les organes de butée 8a de la trajectoire des moyens mobiles 6a, 6b, 6c ou 7a, 7b, 7c ou, le cas échéant, du ou des vantaux 4 ou 5 en vue de permettre, en cas d'urgence, la réouverture de ladite porte 1 ou 2 associée lorsque celle-ci est dans la position entrouverte de sécurité.Preferably, the or each non-return system 8 may comprise a support 8d adapted to support the one or more stop members 8a and holding and release means 9. The support 8d can be disengageable so that it can be, thanks to said means of maintaining and release 9, on the one hand, fixedly held in a position ensuring normal operation of said non-return system 8 ( figure 5 ) and, on the other hand, released in order to make it possible, in the locking state of the latter, to move or tilt the support 8d under the effect of a thrust stress exerted on the thrust member or members 8a in the stop position ( figure 4 ). This is so as to erase the abutment member (s) 8a from the path of the movable means 6a, 6b, 6c or 7a, 7b, 7c or, as the case may be, of the leaf (s) 4 or 5 in order to allow, in case of emergency, the reopening of said door 1 or 2 associated when it is in the open security position.

Le basculement ou le déplacement du support 8d du ou de chaque système anti-retour 8 peut être obtenu sous l'effet d'une contrainte de poussée exercée sur le ou les organes de butée 8a par le ou les vantaux 4 ou 5 ou les moyens mobiles 6a, 6b, 6c ou 7a, 7b, 7c lorsque ces derniers sont en contact de butée avec le ou les organes de butée 8a. Ceci peut être exécuté par une personne exerçant une poussée forcée sur le ou les vantaux 4 ou 5 tendant à réouvrir la porte 1 ou 2 correspondante lorsque celle-ci se trouve dans la position entrouverte de sécurité.The tilting or the displacement of the support 8d of the or each non-return system 8 may be obtained under the effect of a thrust stress exerted on the abutment member (s) 8a by the leaf (s) 4 or 5 or the means movable 6a, 6b, 6c or 7a, 7b, 7c when they are in abutting contact with the abutment member (s) 8a. This can be performed by a person exerting a forced push on the leaf or leaves 4 or 5 tending to reopen the door 1 or 2 corresponding when it is in the open security position.

Dans une forme de réalisation préférentielle du ou de chaque système anti-retour 8, celui-ci peut comprendre au moins un boîtier 8c, 8d abritant le ou plusieurs organes de butée 8a et leurs moyens d'actionnement 8b de sorte que le ou chaque organe de butée 8a soit, à l'état de verrouillage dudit système anti-retour 8, saillant du boîtier 8c, 8d, par une ouverture 8e pratiquée à cet effet dans ce dernier, ou, à l'état de déverrouillage du système anti-retour 8, escamoté, par la ou l'une des ouvertures 8e, dans le boîtier 8c (notamment figures 4 et 5).In a preferred embodiment of the or each non-return system 8, it may comprise at least one housing 8c, 8d housing the one or more abutment members 8a and their actuating means 8b so that the or each organ stop 8a is, in the locking state of said non-return system 8, protruding from the housing 8c, 8d, by an opening 8e made for this purpose in the latter, or, in the unlocked state of the anti-return system 8, retracted, by the or one of the openings 8e, in the housing 8c (in particular figures 4 and 5 ).

Dans une forme de réalisation préférentielle du ou de chaque boîtier 8c, 8d, celui-ci peut comprendre avantageusement deux parties de boîtier 8c et 8d emboîtées, au moins partiellement, l'une dans l'autre et montées pivotantes l'une par rapport à l'autre autour d'un axe transversal 8f, dont l'une 8d peut former le support débrayable et l'autre 8c peut être fixe (notamment figures 4 et 5). Plus particulièrement, la partie de boîtier 8c peut être fixée sur un montant ou une poutre support 6f du système d'ouverture et/ou de fermeture 6 ou 7 correspondant, elle-même fixée sur une partie fixe du dispositif selon la présente invention, par exemple le cadre dormant 4a ou 5a de la porte 1 ou 2 associée (figures 1, 2 et 3).In a preferred embodiment of the or each housing 8c, 8d, it may advantageously comprise two housing portions 8c and 8d nested, at least partially, one in the other and pivotally mounted relative to each other. the other around a transverse axis 8f, one of which 8d can form the disengageable support and the other 8c can be fixed (in particular figures 4 and 5 ). More particularly, the housing part 8c can be fixed to a support post or beam 6f of the opening and / or closing system 6 or 7 corresponding, itself fixed on a fixed part of the device according to the present invention, by example the sleeping frame 4a or 5a of the associated door 1 or 2 ( figures 1 , 2 and 3 ).

D'autre part, comme on peut le voir notamment sur la figure 2 la partie de boîtier 8c fixe peut comprendre une ouverture 8g permettant le passage des moyens d'actionnement 8b, lorsque leurs dimensions le nécessite, lors du pivotement ou du basculement de la partie de boîtier 8b.On the other hand, as can be seen in particular on the figure 2 the fixed housing portion 8c may comprise an opening 8g allowing the passage of the actuating means 8b, when their dimensions require it, during the pivoting or tilting of the housing portion 8b.

En outre les moyens de maintien et de libération 9 peuvent consister en une ventouse électromagnétique comportant un électroaimant 9a fixé dans l'une des parties de boîtier 8c et une plaque métallique 9b fixée dans l'autre partie de boîtier 8d mobile et étant apte à coopérer avec ledit électroaimant 9a afin de maintenir fixement, à l'état d'activation de ladite ventouse, la partie de boîtier 8d mobile (figure 5) et, en cas d'urgence, lorsque le système anti-retour 8 est à l'état de verrouillage et à l'état de désactivation de ladite ventouse 9, de libérer la partie de boîtier 8d mobile de sorte à permettre son pivotement ou son basculement sous ladite contrainte de poussée (figure 4).In addition, the holding and release means 9 may consist of an electromagnetic suction cup comprising an electromagnet 9a fixed in one of the housing parts 8c and a metal plate 9b fixed in the other mobile housing part 8d and being able to cooperate. with said electromagnet 9a in order to hold firmly, in the state of activation of said suction cup, the mobile housing part 8d ( figure 5 ) and, in an emergency, when the non-return system 8 is in the locked state and in the deactivated state of said suction cup 9, to release the movable casing portion 8d so as to allow its pivoting or its tilting under said pushing constraint ( figure 4 ).

Ainsi, en cas d'urgence, lorsque le système anti-retour 8 est à l'état de verrouillage, une personne peut commander la désactivation de la ventouse grâce à un moyen de commande de désactivation, non représenté, et libérer ainsi la partie de boîtier 8d mobile dans le but précité.Thus, in case of emergency, when the non-return system 8 is in the locked state, a person can control the deactivation of the suction cup by deactivation control means, not shown, and thus release the part of 8d mobile housing for the aforementioned purpose.

Par ailleurs, un ressort ou autre système de rappel peut être prévu pour ramener automatiquement le support ou la partie de boîtier 8d dans sa position normale après sollicitation sous contrainte.Furthermore, a spring or other return system can be provided to automatically return the support or the housing portion 8d in its normal position after stressing.

Lorsque la présente invention prévoit un état d'activation du ou de chaque système anti-retour à l'état de préverrouillage, cet état sera considéré comme précédent l'état de verrouillage, c'est-à-dire une position d'attente dudit état de verrouillage.When the present invention provides an activation state of the or each anti-return system in the pre-lock state, this state will be considered as preceding the lock state, that is to say a waiting position of said lock state.

Un exemple de fonctionnement d'un dispositif selon la présente invention comprenant deux portes 1 et 2 pivotantes associées chacune à un système anti-retour 8 peut être le suivant :

  • En position de repos, les portes 1 et 2 sont fermées, une personne 10 peut alors se présenter devant l'une desdites portes ou porte 1 d'entrée pour entrer dans la chambre 3. Après autorisation, la porte 1 d'entrée s'ouvre ou est libérée en ouverture et la personne 10 entre dans la chambre 3 (figure 9a). La porte 1 d'entrée se referme alors automatiquement grâce au système d'ouverture et/ou de fermeture 6, puis lorsque la porte 1 d'entrée atteint une position de fermeture ou position entrouverte de sécurité, la ou l'une des unités de commande électroniques commande, suite à la détection de la position entrouverte de sécurité, d'une part, la mise à l'état de verrouillage du système anti-retour 8 associé à la porte 1 d'entrée et, d'autre part, l'ouverture de l'autre porte 2 ou porte 2 de sortie (figures 9b et 9c). Le dispositif selon la présente invention permet alors à la personne 10 autorisée de sortir de la chambre 3 par la porte 2 de sortie, tout en ne permettant pas à une autre personne non autorisée d'entrer dans la chambre 3 par la porte 1 d'entrée qui est soit en cours de fermeture dans la position entrouverte de sécurité, soit complètement fermée.
An example of operation of a device according to the present invention comprising two pivoting doors 1 and 2 each associated with a non-return system 8 may be the following:
  • In the rest position, the doors 1 and 2 are closed, a person 10 can then be in front of one of the said doors or entry door 1 to enter the room 3. After authorization, the door 1 input s' opens or is released in opening and the person 10 enters room 3 ( figure 9a ). The entrance door 1 then closes automatically thanks to the opening and / or closing system 6, and when the entrance door 1 reaches a closed position or open security position, the one or one of the electronic control command, following the detection of the open security position, a part, the locking state of the anti-return system 8 associated with the input gate 1 and, secondly, the opening of the other gate 2 or gate 2 ( Figures 9b and 9c ). The device according to the present invention then allows the authorized person to leave the chamber 3 by the exit door 2, while not allowing another unauthorized person to enter the chamber 3 by the door 1 of input that is either closing in the open security position or completely closed.

Par ailleurs, grâce au dispositif selon la présente invention, si une autre personne autorisée se présente devant la porte 1 d'entrée complètement fermée, alors que la porte 2 de sortie n'est pas encore complètement fermée mais se trouve dans la position entrouverte de sécurité, la porte 1 d'entrée peut quand même s'ouvrir ou être libérée en ouverture et, du fait de la mise à l'état de verrouillage du système anti-retour 8 associé à la porte 2 de sortie, aucune autre personne ne peut entrer dans la chambre 3 par la porte 2 de sortie alors en phase de fermeture et se trouvant encore dans la position entrouverte de sécurité.Furthermore, thanks to the device according to the present invention, if another authorized person is in front of the completely closed entrance door 1, while the exit door 2 is not yet completely closed but is in the open position of safety, the entrance door 1 can still open or be released opening and, due to the setting lock state of the anti-return system 8 associated with the output door 2, no other person can enter the chamber 3 by the exit door 2 then in the closing phase and still in the open security position.

Selon une caractéristique additionnelle du dispositif selon la présente invention, celui-ci peut comprendre en outre un système de reconnaissance, par exemple biométrique, non représenté. Dans ce cas, la présente invention peut prévoir que la porte 2 de sortie s'ouvre ou soit libérée en ouverture à condition que le système anti-retour 8 associé soit activé ou enclenché et que la reconnaissance soit validée.According to an additional feature of the device according to the present invention, it may further comprise a recognition system, for example biometric, not shown. In this case, the present invention can provide that the output door 2 opens or is released in opening provided that the associated anti-return system 8 is activated or engaged and recognition is validated.

Un tel dispositif selon la présente invention offre ainsi offre les avantages suivants :

  • diminution du temps de cycle tout en conservant les fonctionnalités de base d'un sas de sécurité c'est-à-dire qu'il ne permet pas de passage en continu,
  • augmentation de la vitesse de passage,
  • le fait d'utiliser un système de butée anti-retour et non pas un système continu du type comprenant un mécanisme de liaison entre les deux portes empêchant de réouvrir ou de repousser le ou les vantaux en arrière, permet de garantir la sécurité des utilisateurs, par exemple contre le coincement des doigts entre les vantaux, la personne pouvant même, avec le dispositif selon la présente invention repousser les vantaux qui ne sont pas bloqués en réouverture dans l'intervalle angulaire de la position de la porte entrouverte,
  • dans le cas où chaque porte 1 ou 2 est associée à un système anti-retour 8, après l'activation du système anti-retour 8 de l'une desdites portes en position entrouverte de sécurité, l'autre porte pourra s'ouvrir ou être libérée en ouverture sans attendre la fermeture complète et/ou le verrouillage de la première porte.
Such a device according to the present invention thus offers the following advantages:
  • reduced cycle time while maintaining the basic functionality of a security lock that is to say that it does not allow continuous passage,
  • increase in the speed of passage,
  • the fact of using a non-return stop system and not a continuous system of the type comprising a connecting mechanism between the two doors preventing reopening or pushing the door or leaves back, ensures the safety of users, for example against the jamming of the fingers between the leaves, the person can even, with the device according to the present invention push the leaves which are not locked reopening in the angular interval of the position of the door ajar,
  • in the case where each door 1 or 2 is associated with a non-return system 8, after the activation of the non-return system 8 of one of said doors in open security position, the other door may open or be released in opening without waiting for the complete closing and / or locking of the first door.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
