Description

La présente invention concerne un dispositif électrique de commande du déverrouillage d'un arbre tournant d'une serrure ainsi que la serrure équipée de ce dispositif. L'invention s'applique à des serrures montées dans une poignée de porte ou dans une boucle de fermeture d'un contenant à accès contrôlés.The present invention relates to an electrical device for controlling the unlocking of a rotating shaft of a lock and the lock equipped with this device. The invention applies to locks mounted in a door handle or in a closure loop of a controlled access container.

Dans le bâtiment, le problème du contrôle des accès est de plus en plus fréquent, comme dans les salles informatiques, les salles blanches, ou encore les postes de commande d'usines.In the building, the problem of access control is more and more frequent, as in computer rooms, clean rooms, or factory control posts.

En effet, lorsqu'une zone est autorisée pour une certaine catégorie de personnes, il faut pouvoir permettre un accès sous contrôle à ces personnes et envisager une éventuelle sortie libre. De plus, les clés sont de plus en plus proscrites car elles n'offrent pas la sécurité de non reproduction et ces systèmes mécaniques, surtout lorsqu'ils sont simples et de faible encombrement peuvent être violés de façon assez aisée.In fact, when an area is authorized for a certain category of people, it must be possible to allow controlled access to these people and consider a possible free exit. In addition, keys are increasingly proscribed because they do not offer the security of non-reproduction and these mechanical systems, especially when they are simple and compact can be violated quite easily.

Les modifications des organigrammes correspondants sont lourdes financièrement et longues. De plus la traçabilité est inexistante.The modifications of the corresponding organization charts are financially burdensome and long. In addition traceability is non-existent.

Aussi, les responsables de la sécurité sont amenés à utiliser des systèmes du type carte magnétique ou carte à puce avec des algorithmes mémorisés, avec ou sans codes personnels.Also, security managers are led to use systems of the magnetic card or smart card type with memorized algorithms, with or without personal codes.

Ces moyens électroniques présentent également des inconvénients car soit ils sont centralisés en information et en énergie ce qui les rend très coûteux, soit ils sont autonomes mais ils sont alors très limités en durée de fonctionnement coûteux à mettre en place. Notamment, ils sont difficilement adaptables en lieu et place des systèmes mécaniques.These electronic means also have disadvantages because either they are centralized in information and energy which makes them very expensive, or they are autonomous but they are then very limited in duration of expensive operation to set up. In particular, they are difficult to adapt instead of mechanical systems.

Il faut donc développer des ensembles de fermeture fiable susceptible de fonctionner avec ces ensembles et l'invention propose des poignées dont la béquille est susceptible d'être manoeuvrée lorsque l'accès est autorisé et d'être immobilisée lorsque l'accès est interdit.It is therefore necessary to develop reliable closure assemblies capable of operating with these sets and the invention proposes handles whose leg is likely to be operated when access is authorized and to be immobilized when access is prohibited.

On connaît des gâches électriques notamment celle décrite dans le brevet européen EP-A-279 878 qui décrit une gâche de porte qui comprend des bobines qui agissent sur un induit extérieur et un induit intérieur avec un organe de manoeuvre d'inversion de façon à assurer un verrouillage ou une libération d'un loquet de serrure. On note que dans cette antériorité, le blocage porte directement sur le loquet et il n'est décrit aucun réarmement.Electric strikes are known, in particular that described in European Patent EP-A-279 878, which describes a door striker which comprises coils which act on an external armature and an inner armature with an inverting maneuvering member so as to ensure locking or releasing a lock latch. Note that in this anteriority, the lock is directly on the latch and no rearming is described.

Le brevet GB-B-2 230 550 décrit une gâche avec des moyens de blocage de la manoeuvre d'une béquille de porte comprenant un levier pivotant et un doigt de blocage dudit levier. Ce doigt est manoeuvré par une platine prévue pour coopérer avec un électro-aimant.GB-B-2 230 550 discloses a strike with means for blocking the operation of a door stand comprising a pivoting lever and a locking finger of said lever. This finger is operated by a plate provided to cooperate with an electromagnet.

Une pente est ménagée sur le levier et le doigt est équipé d'un galet qui roule sur la pente.A slope is provided on the lever and the finger is equipped with a roller which rolls on the slope.

Aussi, même lorsqu'une poussée importante est exercée sur la porte, et que l'électro-aimant n'est plus alimenté par exemple sur commande d'un organe de sécurité, la porte peut quand même s'ouvrir.Also, even when a large thrust is exerted on the door, and that the electromagnet is no longer supplied for example on command of a security organ, the door can still open.

Il s'agit essentiellement d'un système de blocage à ouverture de sécurité anti-panique.It is essentially a blocking system with panic security opening.

Le document US-4.656.850 décrit un dispositif électrique de commande d'accouplement en rotation d'un arbre tournant d'une serrure, notamment solidaire d'au moins une poignée de porte, ladite porte étant équipée de moyens de détection de signes d'identification, notamment d'un lecteur de carte magnétique ou à puce, lesdits moyens pouvant émettre un signal de déclenchement, le dispositif comprenant des moyens électromagnétiques prévus pour recevoir ladite impulsion électrique et agissant sur de moyens mécaniques d'accouplement/désaccouplement de l'arbre tournant susceptibles d'occuper deux positions, une première position dans laquelle l'arbre tournant est accouplé avec le reste des moyens mécaniques et une seconde position dans laquelle l'arbre tournant est désaccouplé des moyens mécaniques. Ainsi, dans la première position, le mouvement de rotation de l'arbre tournant entraîne le mouvement de la gâche, alors que dans la seconde position, le mouvement de rotation de l'arbre tournant n'entraîne pas le mouvement de la gâche. On constate que selon cet agencement, la rotation de l'arbre tournant est toujours possible si bien que l'utilisateur ne sait pas s'il est autorisé ou non à ouvrir la porte. Ainsi il peut actionner plusieurs fois la poignée, et éventuellement la détériorer, avant de s'apercevoir qu'il n'est pas autorisé à ouvrir la porte. Selon ce document, les moyens électromagnétiques sont de type plongeur, si bien qu'il existe des pièces qui coulissent les unes par rapport aux autres engendrant nécessairement des frottements qui induisent automatiquement une usure prématurée et une consommation électrique importante.The document US Pat. No. 4,656,850 describes an electrical device for controlling the coupling in rotation of a rotating shaft of a lock, in particular secured to at least one door handle, said door being equipped with means for detecting signs of damage. identification, in particular of a magnetic card reader or chip, said means being able to emit a triggering signal, the device comprising electromagnetic means provided to receive said electrical pulse and acting on mechanical coupling / uncoupling means of the rotating shaft capable of occupying two positions, a first position in which the rotating shaft is coupled with the rest of the mechanical means and a second position in which the rotating shaft is uncoupled from the mechanical means. Thus, in the first position, the rotational movement of the rotating shaft causes the movement of the striker, while in the second position, the rotational movement of the rotating shaft does not cause the movement of the striker. It is found that according to this arrangement, the rotation of the rotating shaft is still possible so that the user does not know whether or not to open the door. Thus he can actuate the handle several times, and possibly deteriorate it, before realizing that he is not authorized to open the door. According to this document, the electromagnetic means are of the plunger type, so that there are parts that slide relative to each other necessarily generating friction that automatically induce premature wear and significant power consumption.

Le dispositif selon la présente invention est tout autre. Il comprend des moyens électromagnétiques qui assure le verrouillage et déverrouillage d'un arbre tournant. Ce dispositif est simple et donc fiable. Par ailleurs, il nécessite une très faible quantité de courant à chaque manoeuvre si bien que la longévité de fonctionnement du dispositif est accrue pour une même réserve d'énergie qui est nécessairement une pile lorsque le dispositif est autonome. De plus l'encombrement de l'ensemble de la poignée ou de la boucle qui utilise ce dispositif est réduit, ce qui facilite son intégration dans une plaque de faible largeur car ce paramètre est particulièrement contraignant, et d'épaisseur acceptable tout en permettant de respecter des entraxes de fixation standards. Cet avantage est particulièrement appréciable lorsqu'il s'agit de remplacer des poignées existantes.The device according to the present invention is quite different. It includes electromagnetic means that locks and unlocks a rotating shaft. This device is simple and therefore reliable. Moreover, it requires a very small amount of current at each operation so that the operating life of the device is increased for the same energy reserve which is necessarily a battery when the device is autonomous. In addition the overall dimensions of the handle or the loop that uses this device is reduced, which facilitates its integration into a plate of small width because this parameter is particularly restrictive, and acceptable thickness while allowing to respect standard fixing distances. This advantage is particularly valuable when it comes to replacing existing handles.

Il est d'autres applications que les serrures montées dans une poignée de porte, c'est ainsi que de nombreux contenants tels que des boîtes, des clapets ou des tiroirs pourraient être équipés de tels dispositifs de contrôle d'accès. Il est même un besoin au niveau de certains dossiers à sangles de grand volume comme les dossiers de justice ou les dossiers de plans dont on souhaiterait savoir quand ils ont été consultés et par qui.There are other applications that the locks mounted in a door handle, so that many containers such as boxes, valves or drawers could be equipped with such access control devices. There is even a need for some large-volume folders such as court files or plan files that we would like to know when they were consulted and by whom.

A cet effet, l'invention concerne un dispositif de commande du mouvement en rotation d'un arbre tournant d'une serrure, comprenant des moyens électromagnétiques prévus pour recevoir une impulsion électrique susceptible d'être émise par des moyens suite à la détection de signes d'identification et agissant sur des moyens mécaniques, caractérisé en ce que les moyens électromagnétiques se présentent sous la forme d'une ventouse à émission de courant et en ce que les moyens mécaniques sont susceptibles d'occuper deux positions sous l'action des moyens électromagnétiques, une première position dite verrouillée dans laquelle ils immobilisent en rotation l'arbre tournant et une seconde position dite déverrouillée dans laquelle ils autorisent le mouvement en rotation de l'arbre tournant, et comprennent une contre-plaque magnétique prévue pour coopérer avec la ventouse entre deux positions, l'une collée contre la ventouse lorsqu'elle est dans son champ magnétique et l'autre écartée de la ventouse lorsqu'elle est hors du champ magnétique.To this end, the invention relates to a device for controlling the rotational movement of a rotating shaft of a lock, comprising electromagnetic means provided for receiving an electric pulse that can be emitted by means following the detection of signs. identification and acting on mechanical means, characterized in that the electromagnetic means are in the form of a current-emitting sucker and in that the mechanical means are capable of occupying two positions under the action of the means electromagnetic, a first so-called locked position in which they immobilize in rotation the rotating shaft and a second so-called unlocked position in which they allow the rotational movement of the rotating shaft, and comprise a magnetic counterplate provided to cooperate with the suction cup between two positions, one stuck against the suction cup when it is in its magnetic field and the other separated from the suction cup when it is out of the magnetic field.

De préférence, la ventouse comprend plus particulièrement un aimant permanent et un circuit pour générer un champ magnétique annulant au moins une partie du champ magnétique de l'aimant permanent à la réception de l'impulsion électrique.Preferably, the suction cup more particularly comprises a permanent magnet and a circuit for generating a magnetic field canceling at least a portion of the magnetic field of the permanent magnet upon receipt of the electrical pulse.

Selon une autre caractéristique, les moyens mécaniques comprennent des moyens de réarmement susceptibles de réintroduire la contre-plaque dans le champ magnétique, de préférence sous la forme d'un levier solidaire de ladite contre-plaque ainsi qu'une jambe de force mobile entre une première position correspondant à la position verrouillée de l'arbre tournant, et une seconde position correspondant à la position déverrouillée de l'arbre tournant.According to another characteristic, the mechanical means comprise rearming means capable of reintroducing the counter-plate into the magnetic field, preferably in the form of a lever secured to said counterplate and a movable strut between a first position corresponding to the locked position of the rotating shaft, and a second position corresponding to the unlocked position of the rotating shaft.

Selon un mode de réalisation particulier, le levier de réarmement comprend une surface plane, venue de fabrication, qui constitue la contre-plaque.According to a particular embodiment, the reset lever comprises a flat surface, coming from manufacture, which constitutes the backplate.

Selon un agencement particulier, le levier de réarmement comprend un ergot dégagé de la jambe de force lorsque la contre-plaque est dans la première position et en appui contre la jambe de force lorsque la contre-plaque est dans la seconde position.In a particular arrangement, the rearming lever comprises a lug released from the strut when the counterplate is in the first position and rest against the strut when the counterplate is in the second position.

Ces moyens mécaniques comprennent des moyens élastiques de rappel disposés entre la jambe de force et le levier de réarmement.These mechanical means comprise elastic return means disposed between the strut and the reset lever.

Afin de permettre une réversibilité aisée, le dispositif comprend une cassette supportant au moins les moyens mécaniques de verrouillage/déverrouillage et la ventouse à émission de courant des moyens électromagnétiques de déverrouillage.In order to allow easy reversibility, the device comprises a cassette supporting at least the mechanical locking / unlocking means and the current-issuing suction cup of the electromagnetic unlocking means.

L'invention couvre aussi la poignée de porte équipée du dispositif précédent et qui comprend en outre un second fouillot muni d'un pion d'entraînement du premier fouillot, lui-même muni d'une lumière pour recevoir ledit pion, ce second fouillot étant solidaire de la béquille intérieure et comportant au moins une pente prévue pour amener la jambe de force de la première position verrouillée à la seconde position déverrouillée.The invention also covers the door handle equipped with the preceding device and which further comprises a second follower provided with a driving pin of the first follower, itself provided with a light for receiving said pin, this second follower being secured to the inner stand and having at least one slope provided to bring the strut from the first locked position to the second unlocked position.

Dans ce cas, la lumière du second fouillot est de dimensions telles que le premier fouillot est entraîné lorsque la jambe de force est dégagée du premier fouillot.In this case, the light of the second follower is of such dimensions that the first follower is driven when the strut is released from the first follower.

L'invention est maintenant décrite selon un mode de réalisation particulier appliqué à une poignée de porte ou à une serrure de contenant, ce mode de réalisation étant non limitatif, la description étant conduite en regard des dessins annexés qui représentent :

Sur les figures 1 et 2, on a représenté une poignée de porte 10 avec un carter 11 recevant une cassette 12 sur laquelle est rapportée une source 14 d'énergie avec un circuit 16 électronique de reconnaissance et de commande, des moyens 18 électromagnétiques de verrouillage/déverrouillage ainsi que des moyens 20 mécaniques de verrouillage/déverrouillage de l'axe tournant d'une serrure, l'ensemble étant couvert par une plaque 22 de propreté dite foncet.Figures 1 and 2, there is shown a door handle 10 with a casing 11 receiving a cassette 12 on which is reported a source 14 of energy with an electronic circuit 16 recognition and control, electromagnetic means 18 locking / Unlocking as well as mechanical means 20 for locking / unlocking the rotating shaft of a lock, the assembly being covered by a so-called freeness plate 22.

On note que, sur les deux figures, les références sont identiques car il y a une symétrie des montages pour porte à ouverture à droite ou à gauche. Il suffit pour cela de retourner la cassette 12 avant son montage dans le carter. Il n'y a aucun démontage de pièces comme cela sera compris à la lecture de la description détaillée qui va suivre.Note that, in both figures, the references are identical because there is a symmetry of mounting for door opening to the right or left. It suffices to return the cassette 12 before mounting in the housing. There is no dismantling of parts as will be understood from reading the detailed description that follows.

Le carter 11 est prévu pour être fixé sur la porte par deux trous 24, à écartement standard.The housing 11 is intended to be fixed to the door by two holes 24, standard spacing.

La source 14 d'énergie électrique est une pile 26. Le circuit 16 électronique de reconnaissance et de commande est relié par un câble 28 à d'autres organes (non représentés) qui n'intéressent pas directement l'invention, à savoir un lecteur de carte ou de puce ou encore tout autre moyen de reconnaissance et d'identification et un vibreur destiné à émettre un son particulier pour confirmer les bonnes ou mauvaises manoeuvres de l'utilisateur.The source 14 of electrical energy is a battery 26. The electronic recognition and control circuit 16 is connected by a cable 28 to other members (not shown) which are not of direct interest to the invention, namely a reader card or chip or any other means of recognition and identification and a vibrator intended to emit a its particular to confirm the good or bad maneuvers of the user.

Un autre câble 30 assure l'alimentation électrique des moyens 18 électromagnétiques.Another cable 30 provides power to the electromagnetic means 18.

Les moyens 18 électromagnétiques de verrouillage/déverrouillage comprennent une ventouse 32 électromagnétique à émission de courant, prévue pour recevoir une contre-plaque 34 métallique, magnétique, susceptible d'être maintenue dans une première position collée contre la ventouse 32 et d'être libérée dans une seconde position. Ce type de ventouse comprend un aimant permanent de forte puissance qui assure une force magnétique constante suffisante pour maintenir la contre-plaque, ou tout autre élément plan métallique et magnétique, collée dès que celle-ci est dans la zone d'attraction. Si on fait circuler un courant dans un bobinage associé disposé dans ladite ventouse, il est possible de générer un champ électromagnétique dont l'intensité est calculée pour annuler au moins en partie, la force magnétique permanente générée par l'aimant, si bien que la contre-plaque n'est plus soumise qu'à la force magnétique permanente diminuée de la force électromagnétique générée lors de l'émission d'une impulsion de courant.The electromagnetic locking / unlocking means 18 comprise a electromagnetic suction cup 32 with current emission, designed to receive a metal counterplate 34, magnetic, capable of being held in a first position glued against the suction cup 32 and to be released into a second position. This type of suction cup comprises a permanent magnet of high power which ensures a constant magnetic force sufficient to maintain the counterplate, or any other metallic and magnetic plane element, glued as soon as it is in the zone of attraction. If a current is circulated in an associated winding disposed in said suction cup, it is possible to generate an electromagnetic field whose intensity is calculated to cancel at least in part, the permanent magnetic force generated by the magnet, so that the Against the plate is subject only to the permanent magnetic force minus the electromagnetic force generated during the emission of a current pulse.

Les moyens mécaniques de verrouillage/déverrouillage comprennent la contre-plaque 34 qui reçoit à sa partie inférieure un levier 36 de réarmement qui est articulé par rapport à la cassette au moyen d'un axe 38, avec un débattement angulaire limité. On note en variante que le levier pourrait être mis en forme pour qu'il présente une surface analogue à celle de la contre-plaque permettant ainsi la suppression de cette contre-plaque.The mechanical locking / unlocking means comprise the counter plate 34 which receives at its lower part a resetting lever 36 which is articulated relative to the cassette by means of an axis 38, with a limited angular movement. It is alternatively noted that the lever could be shaped so that it has a surface similar to that of the against-plate thus allowing the removal of this against-plate.

Un joint 40, torique, permet de rattraper les éventuels défauts de parallélisme entre la contre-plaque et ledit levier et c'est là notamment l'intérêt de cette contre-plaque. La liaison entre la contre-plaque et la ventouse assure un certain débattement angulaire, si bien que la force de l'aimant permanent est exercée sur toute la surface de la contre-plaque par auto-orientation de celle-ci.A seal 40, ring, makes it possible to make up any possible defects of parallelism between the counterplate and said lever and this is particularly the interest of this against-plate. The connection between the backplate and the suction cup provides a certain angular displacement, so that the force of the permanent magnet is exerted on the entire surface of the backplate by self-orientation thereof.

Ce levier des moyens 20 mécaniques de verrouillage/déverrouillage présente un ergot 42 dont on déterminera l'utilité lors de la description du fonctionnement.This lever means 20 mechanical locking / unlocking has a lug 42 which will determine the utility during the description of the operation.

De même, le levier porte à son extrémité, une came 44 de réarmement appartenant aux moyens de réarmement.Similarly, the lever carries at its end, a reset cam 44 belonging to the resetting means.

Ces moyens 20 mécaniques de verrouillage/déverrouillage sont complétés par une jambe de force 46 qui est articulée et qui peut prendre deux positions l'une de verrouillage du carré de manoeuvre comme cela sera expliqué ultérieurement et une position déverrouillée dans laquelle le carré de manoeuvre est libre.These mechanical locking / unlocking means 20 are completed by a strut 46 which is hinged and which can take two positions one of locking of the maneuvering square as will be explained later and an unlocked position in which the maneuvering square is free.

L'articulation est ramenée à sa plus simple expression puisque le talon de la jambe de force est simplement en appui sur le fond d'un logement 48 dont les parois assurent le guidage.The joint is reduced to its simplest expression since the heel of the strut is simply supported on the bottom of a housing 48 whose walls provide guidance.

Un ressort 49 de rappel est interposé entre le levier de réarmement et la jambe de force.A return spring 49 is interposed between the reset lever and the strut.

Les moyens 20 mécanique de verrouillage/déverrouillage comprennent de plus un fouillot 50, ayant sensiblement la forme d'un disque, monté pivotant autour d'un axe 52. Ce fouillot est muni en son centre d'un trou 54 à section carrée, prévu pour recevoir, de façon connue un axe carré de manoeuvre, dit "carré", lui-même entraîné par une béquille, visible en trait discontinu sur la figure 3A. Ce carré permet l'entraînement de l'arbre tournant de la serrure.The mechanical locking / unlocking means 20 further comprise a follower 50, having substantially the shape of a disc, pivotally mounted about an axis 52. This follower is provided at its center with a hole 54 of square section, provided to receive, in known manner a square axis of maneuver, said "square", itself driven by a crutch, visible in broken lines in Figure 3A. This square allows the drive of the rotating shaft of the lock.

Ce fouillot 50 est symétrique et comporte un doigt 56 orienté, en position stable, suivant l'axe vertical.This follower 50 is symmetrical and has a finger 56 oriented, in a stable position, along the vertical axis.

De part et d'autre de ce doigt, de façon également symétrique, sensiblement à 90°, il est ménagé un décrochement 58. Suivant le montage ouverture à droite ou à gauche, le décrochement correspondant est apte à coopérer avec l'extrémité libre de la jambe de force 46, dans la position verrouillée comme cela sera expliqué par la suite.On either side of this finger, also symmetrically, substantially at 90 °, a recess 58 is provided. Depending on the mounting opening on the right or on the left, the corresponding recess is able to cooperate with the free end of the strut 46, in the locked position as will be explained later.

En effet, seul l'un des décrochements est nécessaire pour un montage donné, la présence des deux décrochements n'étant justifiée que par la possibilité de réaliser des montages pour porte à ouverture à droite ou à gauche comme cela est montré sur les figures 1 et 2.Indeed, only one of the recesses is necessary for a given assembly, the presence of the two recesses being justified only by the possibility of making assemblies for opening door to the right or left as shown in Figures 1 and 2.

Le fonctionnement du dispositif selon l'invention est maintenant décrit en regard des figures 3A à 3G, les références des éléments identiques étant reportées sur les différentes figures.The operation of the device according to the invention is now described with reference to FIGS. 3A to 3G, the references of identical elements being shown in the various figures.

Sur la figure 3A, la béquille est représentée en trait discontinu. Cette béquille est inclinée d'un angle qui est exagéré pour les besoins de représentation mais qui reste de l'ordre de quelques degrés, 3 à 5° pour donner une valeur représentative.In Figure 3A, the stand is shown in broken lines. This crutch is inclined at an angle that is exaggerated for the purposes of representation but remains of the order of a few degrees, 3 to 5 ° to give a representative value.

Cette très faible rotation est autorisée par un jeu ménagé entre l'extrémité libre de la jambe de force 46 et le décrochement 58 correspondant dont le fouillot 50 est muni. Ce jeu permet à l'utilisateur de sentir que la manoeuvre est possible mais qu'un système de verrouillage interdit une manoeuvre angulaire plus importante permettant d'ouvrir la porte. Ceci évite que l'utilisateur force de façon démesurée, en imaginant que la béquille est coincée par un dysfonctionnement. De plus cela permet de façon sûre un repositionnement de la jambe de force dans le décrochement du fouillot.This very small rotation is permitted by a clearance formed between the free end of the strut 46 and the recess 58 corresponding whose follower 50 is provided. This game allows the user to feel that the maneuver is possible but that a locking system prohibits a greater angular maneuver to open the door. This prevents the user from excessive force, imagining that the stand is stuck by a malfunction. In addition, it surely allows a repositioning of the strut in the recess of the follower.

On constate que, dans cette phase, la jambe de force assure le verrouillage des moyens 20 mécaniques et plus particulièrement du fouillot 50. On note d'ailleurs que dans cette position, la contre-plaque est collée contre la ventouse dans la première position de rappel, l'aimant permanent assurant son attraction pleine et entière.It can be seen that, in this phase, the strut locks the mechanical means and more particularly the follower 50. Moreover, it is noted that in this position, the counter-plate is glued against the suction cup in the first position of reminder, the permanent magnet ensuring its full attraction.

Le levier 40 de réarmement, solidaire de la contre-plaque 34, est lui aussi dans sa première position si bien que le ressort 49 est tendu, la force de rappel exercée étant maximale. La jambe de force a tendance à être maintenue dans la première position de déverrouillage même en cas d'actionnement à chocs de la béquille ou en cas de chocs portés sur la poignée.The reset lever 40, integral with the counter-plate 34, is also in its first position so that the spring 49 is tensioned, the restoring force exerted being maximum. The strut tends to be maintained in the first unlocking position even in case of shock actuation of the stand or in case of impact on the handle.

Lorsque l'utilisateur est autorisé et qu'il est muni de moyens d'identification reconnus par les moyens de détection et d'émission d'un ordre, disposés à l'extérieur du local dont la porte, munie du dispositif selon l'invention, interdit l'entrée, il se produit les mouvements décrits ci-après.When the user is authorized and is provided with identification means recognized by the detection and emission means of an order, arranged outside the room whose door, provided with the device according to the invention , prohibits the entry, it occurs the movements described below.

Une impulsion électrique est envoyée par les moyens 16 électroniques à la ventouse 32 pour annuler au moins une partie de la force d'attraction de l'aimant permanent. Cet effort négatif s'ajoute à celui du ressort.An electrical pulse is sent by the electronic means 16 to the pad 32 to cancel at least a portion of the attraction force of the permanent magnet. This negative effort is added to that of the spring.

La position des différents organes qui en découle est montrée sur la figure 3B.The position of the various organs that results is shown in Figure 3B.

Le ressort 49 qui exerce une traction continue entre la contre-plaque 34 et la jambe de force 46, provoque le décollement de ladite contre-plaque de la ventouse. Lorsque l'impulsion est passée, l'aimant permanent retrouve toute sa puissance et émet son champ magnétique de façon normale. Par contre, la contre-plaque, décollée de la ventouse est à une distance d'entrefer trop importante pour que la contre-plaque soit rappelée, surtout que ladite contre-plaque est toujours soumise à l'effort de rappel du ressort.The spring 49 which exerts a continuous traction between the counterplate 34 and the strut 46, causes the detachment of said counter plate of the suction cup. When the pulse is passed, the permanent magnet regains its power and emits its magnetic field in a normal way. On the other hand, the counterplate, detached from the suction cup, is at a gap distance that is too great for the backplate to be recalled, especially since said backplate is still subjected to the return force of the spring.

On note que l'ergot 42 du levier de réarmement est distant de la jambe de force en position stable, en sorte de permettre le décollement de la contre-plaque et le mouvement angulaire du levier même si la jambe de force est bloquée dans la première position.Note that the lug 42 of the reset lever is remote from the strut in a stable position, so as to allow the detachment of the backplate and the angular movement of the lever even if the strut is blocked in the first position.

En effet, le système est instable autour de l'axe de rotation 38 du levier de réarmement.Indeed, the system is unstable around the axis of rotation 38 of the reset lever.

Dès lors, deux situations sont possibles suivant que l'utilisateur exerce une action sur la béquille ou non :

  • si l'utilisateur exerce un effort suffisamment important sur la béquille, le déplacement de la jambe de force est bloqué et le fouillot, donc la béquille, ne peut aller plus loin. Dès que l'utilisateur relâche sa pression, le poids du levier avec la contre-plaque et l'impulsion conférée par le ressort assurent un basculement de l'ensemble de la contre-plaque et du levier de réarmement autour de l'articulation 38 et consécutivement le déplacement de la jambe de force dans la seconde position dite déverrouillée, par l'intermédiaire de l'ergot 42 qui vient en appui sur la jambe de force. C'est la position représentée figure 3C.
  • si l'utilisateur n'exerce aucun effort, la jambe de force est libre de se déplacer de la première à la seconde positon et d'assurer un déverrouillage instantané.
Therefore, two situations are possible depending on whether the user exerts an action on the crutch or not:
  • if the user exerts sufficient effort on the stand, the movement of the strut is blocked and the follower, so the crutch, can not go further. As soon as the user releases his pressure, the weight of the lever with the counter-plate and the pulse imparted by the spring ensure a tilting of the assembly of the backplate and the reset lever around the articulation 38 and consecutively the displacement of the strut in the second so-called unlocked position, via the lug 42 which bears on the strut. This is the position shown in Figure 3C.
  • if the user exerts no effort, the strut is free to move from the first to the second position and ensure an instant unlock.

Lors du mouvement de rotation de la béquille, le levier de réarmement se rapproche du doigt 56 du fouillot 50 tandis que la jambe de force est écartée, autorisant la rotation du fouillot. Dès que le fouillot a amorcé une rotation supérieure au jeu angulaire prévu initialement et compris entre 3 et 5°, la jambe de force est maintenue dans la seconde position avec impossibilité de blocage de la rotation du fouillot comme montré sur la figure 3D.During the rotation movement of the stand, the reset lever is closer to the finger 56 of the follower 50 while the strut is removed, allowing the rotation of the follower. As soon as the follower has initiated a rotation greater than the initial angular clearance initially provided and between 3 and 5 °, the strut is maintained in the second position with impossibility of blocking the rotation of the follower as shown in FIG. 3D.

La rotation du fouillot 50 et du doigt 56 dont il est porteur amène ledit doigt en contact avec la came 44 du levier de réarmement, comme montré sur la figure 3E. De ce fait, le levier de réarmement est soulevé, entraînant la contre-plaque 34 jusqu'à ce que celle-ci se trouve dans le champ magnétique de l'aimant permanent de la ventouse qui assure alors le maintien de cette contre-plaque. Simultanément, le ressort 49 de rappel est bandé. Le ressort exerce alors un effort de rappel important sur la jambe de force qui est toujours immobilisée dans la seconde position par le fouillot 50. Le joint torique assure le rattrapage des défauts de parallélisme.The rotation of the follower 50 and the finger 56 which it carries brings said finger into contact with the cam 44 of the reset lever, as shown in Figure 3E. As a result, the reset lever is raised, driving the counter-plate 34 until it is in the magnetic field of the permanent magnet of the suction cup which then ensures the maintenance of this against-plate. Simultaneously, the return spring 49 is bandaged. The spring then exerts a strong return force on the strut which is always immobilized in the second position by the follower 50. The O-ring ensures the catching of parallelism defects.

On note que le réarmement est obtenu après une faible course angulaire pour être certain d'obtenir le réarmement dans tous les cas en tenant compte des différents agencements de serrures et des jeux existants, notamment ceux entre l'ouvrant et le dormant.Note that the rearming is obtained after a small angular stroke to be sure to get reset in all cases taking into account the different lock arrangements and existing games, including those between the opening and the frame.

Sur la figure 3F, on constate que la came est prolongée avec un profil curviligne correspondant au mouvement de l'extrémité du doigt du fouillot, ceci afin d'éviter dans tous les cas le passage du doigt derrière la came si l'utilisateur, par une manoeuvre intempestive, de la béquille venait à dépasser la rotation angulaire autorisée. Pendant ce mouvement, la gâche, non représentée, de la porte est actionnée à l'ouverture, ceci de façon connue.In FIG. 3F, it can be seen that the cam is extended with a curvilinear profile corresponding to the movement of the end of the finger of the follower, this in order to avoid in all cases the passage of the finger behind the cam if the user, by an untimely maneuver, the kickstand exceeded the permitted angular rotation. During this movement, the striker, not shown, of the door is actuated at the opening, this in a known manner.

Dès que l'utilisateur interrompt la pression exercée sur la béquille, les moyens de rappel de la gâche assurent un retour en position stable du fouillot et le rappel en position initiale de la béquille qui en est solidaire, comme montré sur la figure 3G.As soon as the user interrupts the pressure exerted on the stand, the return means of the striker ensure a return to stable position of the follower and the return to the initial position of the stand which is secured to it, as shown in Figure 3G.

On note aussi que, dès que le fouillot est revenu en position, au jeu angulaire près, la jambe de force, soumise à l'action du ressort 49 a repris sa position première et son extrémité libre est revenue se loger dans le décrochement correspondant.It should also be noted that as soon as the follower has returned to its position, with the angular clearance close to it, the strut, subjected to the action of the spring 49 has resumed its first position and its free end has returned to lodge in the corresponding recess.

La position suivante est celle de la figure 2 initiale, montrant ainsi le cycle complet.The next position is that of the initial figure 2, thus showing the complete cycle.

Ainsi, la force emmagasinée par le ressort est fournie par l'utilisateur lorsqu'il manoeuvre la béquille, la ventouse n'ayant besoin que de déverrouiller le mécanisme par libération de la contre-plaque.Thus, the force stored by the spring is provided by the user when operating the stand, the suction pad only needing to unlock the mechanism by releasing the counterplate.

On a indiqué le fonctionnement dans le cas d'une serrure comprenant un carré qui traverse la porte et qui relie les deux béquilles de la poignée.Operation has been indicated in the case of a lock comprising a square which passes through the door and which connects the two crutches of the handle.

Dans certains cas, pour des raisons de sécurité, il faut que l'ouverture à partir de l'intérieur de la pièce soit autorisée en toutes circonstances, sans même exercer un contrôle. L'accès de la pièce équipée d'une porte munie du dispositif selon l'invention est donc contrôlé mais la sortie est libre.In some cases, for security reasons, the opening from the inside of the room must be authorized in all circumstances, without even exercising control. Access to the room equipped with a door provided with the device according to the invention is therefore controlled but the output is free.

La manoeuvre des béquilles des deux poignées est distincte. Le carré est alors réalisé en deux parties, l'une solidaire du premier fouillot comme montré précédemment et l'autre solidaire d'un second fouillot 60, les deux fouillots 50 et 60 étant entraînés en rotation par un pion 62, comme montré sur la figure 4A.The operation of the crutches of the two handles is distinct. The square is then made in two parts, one secured to the first follower as shown above and the other secured to a second follower 60, the two nuts 50 and 60 being rotated by a pin 62, as shown in FIG. Figure 4A.

Le premier fouillot 50, représenté en trait discontinu, comporte à cet effet une lumière 64 curviligne, ouverte qui reçoit le pion 62. Cette lumière du premier fouillot est d'une dimension telle qu'elle autorise un déplacement angulaire du second fouillot de quelques degrés avant d'être entraîné par lui, par exemple 10°.The first follower 50, shown in broken lines, comprises for this purpose a curvilinear open light 64 which receives the pin 62. This light of the first follower is of such a size as to allow an angular displacement of the second follower of a few degrees. before being driven by him, for example 10 °.

Le second fouillot comprend aussi deux pentes 66, dont une seulement est utilisée, la seconde, symétrique étant réalisée pour des besoins de symétrie et de réversibilité.The second follower also comprises two slopes 66, only one of which is used, the second symmetrical being made for purposes of symmetry and reversibility.

La pente 66 concernée est ménagée sensiblement avec un même positionnement angulaire que les décrochements 58 du premier fouillot en sorte de pouvoir coopérer avec l'extrémité libre de la jambe de force 46.The slope 66 concerned is arranged substantially with the same angular positioning as the recesses 58 of the first follower so as to cooperate with the free end of the strut 46.

Par contre, ce second fouillot est exempt de doigt.By cons, this second follower is free of finger.

Comme cela est visible sur la figure 4B, la rotation du seul second fouillot sur la première plage de l'ordre de 10° telle que définie, provoque le déverrouillage de la jambe de force 46 grâce à la pente 66 correspondante pour autoriser la manoeuvre de la béquille intérieure. Lorsque le pion du second fouillot vient en butée dans la lumière 64 du premier fouillot, il y a alors entraînement conjoint des deux fouillots et ouverture de la gâche de façon connue.As can be seen in FIG. 4B, the rotation of the only second follower on the first range of the order of 10 ° as defined causes the unlocking the strut 46 through the corresponding slope 66 to allow the operation of the inner stand. When the pin of the second follower abuts in the light 64 of the first follower, there is then joint drive of the two nuts and opening the keeper in a known manner.

On note que, durant cette manoeuvre, les moyens électromagnétiques ne sont pas sollicités et le levier de réarmement et la contre-plaque restent en position première.Note that during this maneuver, the electromagnetic means are not solicited and the reset lever and the backplate remain in the first position.

Cet agencement est particulièrement satisfaisant puisqu'il permet une ouverture de sécurité à tout instant de l'intérieur sans solliciter les moyens électromagnétiques donc sans consommation d'énergie. Ceci conduit à des durées de vie de la source d'énergie de plusieurs années même en cas d'usage intensif.This arrangement is particularly satisfactory since it allows a safety opening at any time from the inside without soliciting the electromagnetic means therefore without energy consumption. This leads to lifetimes of the energy source of several years even in case of intensive use.

On note aussi que les différents organes sont simples si bien que l'ensemble est fiable et les risques de dysfonctionnement sont très limités.We also note that the different organs are simple so that all is reliable and the risk of malfunction is very limited.

On note aussi que l'accès à la pièce concernée est interdit en cas de manque d'énergie électrique dispensé par la source si bien que la sécurité face à l'intrusion intempestive est garantie tout en laissant aux personnes situées à l'intérieur la possibilité de sortir librement.It is also noted that access to the room in question is forbidden in the event of a lack of electrical energy provided by the source, so that security against inadvertent intrusion is guaranteed while leaving people inside the room to go out freely.

Dans les différentes variantes de réalisation, on a présenté les moyens 20 mécaniques, les moyens 18 électromagnétiques et les moyens pour émettre une impulsion électrique d'un même côté de la porte mais les moyens pour émettre une impulsion électrique par exemple peuvent être disposés du côté de la porte opposé à celui qui supporte le reste du dispositif. Cette facilité d'agencement permet de répartir les encombrements si besoin est.In the different embodiments, the mechanical means, the electromagnetic means and the means for emitting an electrical pulse on the same side of the door have been presented, but the means for emitting an electric pulse for example can be arranged on the side of the door. from the opposite door to the one that supports the rest of the device. This ease of arrangement allows to distribute the congestion if necessary.

Sur les figures 5A à 5C, on a représenté un agencement d'un même dispositif appliqué par exemple à une serrure d'un contenant. Le synoptique correspondant montre comment travaille le dispositif dans cet agencement.FIGS. 5A to 5C show an arrangement of the same device applied for example to a lock of a container. The corresponding block diagram shows how the device works in this arrangement.

Sur la figure 5A, on retrouve certains éléments identiques et précédemment décrits et on affecte à ces éléments les mêmes références pour une simplification des dessins tandis que les éléments équivalents portent les mêmes références augmentées de 100 et les nouveaux éléments portent des références à partir de 200.In FIG. 5A, certain identical and previously described elements are found and the same references are assigned to these elements for a simplification of the drawings while the equivalent elements carry the same elements. same references increased by 100 and the new elements carry references from 200.

Le fouillot 150 est modifié par la présence d'une denture 210 en partie inférieure prévue pour engrener avec les dents d'une crémaillère 212. Cette crémaillère est guidée en translation par tout moyen adéquat qui ne fait pas partie de la présente invention et qui relève des compétences de l'homme de l'art en fonction de l'application.The follower 150 is modified by the presence of a toothing 210 in the lower part intended to mesh with the teeth of a rack 212. This rack is guided in translation by any suitable means which is not part of the present invention and which falls under skills of those skilled in the art depending on the application.

En position d'attente, comme montré sur la figure 1, le fouillot 150 est orienté avec son doigt 156 vertical.In standby position, as shown in Figure 1, the follower 150 is oriented with its finger 156 vertical.

La crémaillère 212 est en place et ses dents coopèrent avec celles portées par le fouillot 150. La jambe de force 146 assure le blocage en rotation du fouillot si bien qu'il est impossible de retirer la crémaillère 212.The rack 212 is in place and its teeth cooperate with those carried by the follower 150. The strut 146 ensures the rotational locking of the follower so that it is impossible to remove the rack 212.

Lorsque l'utilisateur est autorisé et qu'il est muni de moyens d'identification reconnus par les moyens de détection et d'émission d'un ordre associés à la serrure du contenant, il se produit les mouvements décrits ci-après.When the user is authorized and is provided with identification means recognized by the detection and emission means of an order associated with the lock of the container, the movements described below occur.

Une impulsion électrique est envoyée par les moyens électroniques à la ventouse 132 pour annuler au moins une partie de la force d'attraction de l'aimant permanent. Cet effort négatif s'ajoute à celui du ressort 149.An electrical pulse is sent by the electronic means to the suction cup 132 to cancel at least a portion of the attraction force of the permanent magnet. This negative effort is added to that of spring 149.

La position des différents organes qui en découle est montrée sur la figure 5B.The position of the different organs that results is shown in Figure 5B.

Le ressort 149 qui exerce une traction continue entre la contre-plaque 134 et la jambe de force 146, provoque le décollement de ladite contre-plaque de la ventouse. Lorsque l'impulsion est passée, l'aimant permanent retrouve toute sa puissance et émet son champ magnétique de façon normale. Par contre, la contre-plaque, décollée de la ventouse est à une distance d'entrefer trop importante pour que la contre-plaque soit rappelée, surtout que ladite contre-plaque est toujours soumise à l'effort de rappel du ressort.The spring 149 which exerts a continuous traction between the counterplate 134 and the strut 146, causes the detachment of said counter plate of the suction cup. When the pulse is passed, the permanent magnet regains its power and emits its magnetic field in a normal way. On the other hand, the counterplate, detached from the suction cup, is at a gap distance that is too great for the backplate to be recalled, especially since said backplate is still subjected to the return force of the spring.

L'utilisateur provoque alors le retrait de la crémaillère par une simple traction dans le sens de la flèche 216, comme montré sur la figure 5C.The user then causes the removal of the rack by a simple pull in the direction of the arrow 216, as shown in Figure 5C.

En variante, il est proposé d'adjoindre un ressort 214 qui provoque la rotation du fouillot 150 dans le sens des aiguilles d'une montre, ce qui éjecte la crémaillère.Alternatively, it is proposed to add a spring 214 which causes the rotation of the follower 150 in the direction of clockwise, which ejects the rack.

Cette crémaillère peut être rendue solidaire d'une sangle ou de tout autre lien tandis que le dispositif électrique de commande de déverrouillage selon l'invention est solidaire d'une autre sangle ou de tout autre lien. Les deux parties peuvent être solidaire d'un volet d'un contenant d'une part et du contenant lui-même d'autre part.This rack can be secured to a strap or other link while the electric unlocking control device according to the invention is secured to another strap or other link. The two parts may be integral with a flap of a container on the one hand and the container itself on the other.

On constate donc une multiplicité d'applications de l'agencement qui vient d'être décrit, ce qui renforce encore les avantages énoncés en préambule.There is therefore a multiplicity of applications of the arrangement that has just been described, which further enhances the advantages stated in the preamble.
