Description

La présente invention concerne un dispositif de verrouillage d'une porte, notamment d'une porte de cabine de toilette, par exemple pour un véhicule ferroviaire, aéronautique, maritime ou routier, ou pour un bâtiment.The present invention relates to a device for locking a door, in particular a toilet door, for example for a railway, aeronautical, maritime or road vehicle, or for a building.

On connaît déjà, dans l'état de la technique, un dispositif de verrouillage d'une porte, comprenant un verrou mobile entre une position de verrouillage et une position de déverrouillage, ainsi que des moyens d'actionnement de ce verrou, propres à déplacer ce verrou entre ses positions de déverrouillage et de verrouillage.Already known in the state of the art, a locking device of a door, comprising a movable latch between a locking position and an unlocking position, and means for actuating this lock, suitable for moving this lock enters its unlocking and locking positions.

Ces moyens d'actionnement sont par exemple formés par un bouton de porte accessible depuis l'intérieur de la cabine, de manière à pouvoir être actionné par un utilisateur désirant s'y enfermer.These actuating means are for example formed by a door button accessible from the inside of the cabin, so as to be actuated by a user wishing to lock himself.

Un tel dispositif de verrouillage comporte généralement d'autres moyens d'actionnement de ce verrou, également propres à déplacer ce verrou entre ses positions de verrouillage et de déverrouillage. Ces autres moyens d'actionnement sont alors destinés à être accessibles depuis l'extérieur de la cabine, au moyen d'un élément d'actionnement, par exemple une clé de forme adaptée.Such a locking device generally comprises other means for actuating this lock, also suitable for moving this lock between its locking and unlocking positions. These other actuating means are then intended to be accessible from outside the cabin, by means of an actuating element, for example a key of suitable shape.

Un tel dispositif de verrouillage permet de définir différents états de verrouillage de la cabine, notamment des états dits « libre », « occupé », et « condamné ».Such a locking device makes it possible to define different locking states of the cabin, in particular so-called "free", "occupied" and "condemned" states.

La cabine est dite dans un état libre lorsqu'un utilisateur peut accéder librement à l'intérieur de la cabine. Dans le cas du dispositif de verrouillage évoqué ci-dessus, la cabine est dans l'état libre lorsque le verrou est en position de déverrouillage.The cabin is said to be in a free state when a user can freely access the interior of the cabin. In the case of the locking device mentioned above, the cabin is in the free state when the lock is in the unlocked position.

La cabine est dite dans un état occupé lorsqu'un utilisateur l'occupe et s'y est enfermé. Dans le cas du dispositif de verrouillage évoqué ci-dessus, le verrou est alors en position de verrouillage, l'utilisateur l'ayant déplacé dans cette position de verrouillage en actionnant le bouton de porte accessible depuis l'intérieur de la cabine.The cabin is said to be in an occupied state when a user occupies it and is locked in it. In the case of the locking device mentioned above, the lock is then in the locked position, the user having moved in this locking position by actuating the door knob accessible from inside the cabin.

Enfin, la cabine est dite dans l'état condamné lorsque son accès est interdit, notamment par un membre d'une équipe technique. Ceci est par exemple le cas lorsque la cabine, ayant été considérée comme non fonctionnelle, est verrouillée volontairement et manuellement par un membre d'une équipe technique. Dans le cas du dispositif de verrouillage évoqué ci-dessus, le verrou a été déplacé dans la position de verrouillage grâce auxdits autres moyens d'actionnement accessible depuis l'extérieur de la cabine.Finally, the cabin is said to be condemned when access is forbidden, in particular by a member of a technical team. This is for example the case when the cabin, having been considered as non-functional, is locked deliberately and manually by a member of a technical team. In the case of the locking device mentioned above, the lock has been moved into the locking position by means of said other actuating means accessible from outside the cabin.

Il est important pour les utilisateurs de pouvoir distinguer l'état occupé de l'état condamné. En effet, dans l'état occupé, les utilisateurs savent qu'un autre utilisateur occupe actuellement la cabine, si bien que cette cabine devrait être libérée prochainement. En revanche, dans l'état condamné, les utilisateurs savent que la cabine restera inaccessible.It is important for users to be able to distinguish the busy state from the condemned state. Indeed, in the busy state, users know that another user is currently occupying the cabin, so this cabin should be released soon. On the other hand, in the condemned state, users know that the cabin will remain inaccessible.

Habituellement, notamment dans certains véhicules ferroviaires, on souhaite répertorier les cabines en état condamné, notamment grâce à la transmission d'un signal de condamnation depuis une cabine en état condamné jusqu'à une unité centrale de contrôle.Usually, particularly in certain railway vehicles, it is desirable to list the cabins in a condemned state, in particular by transmitting a locking signal from a locked cabin to a central control unit.

A cet effet, la cabine est habituellement équipée d'une serrure supplémentaire qui, lorsqu'elle est activée, émet un signal de condamnation à destination de l'unité centrale de contrôle, selon lequel la cabine est condamnée. Il est à noter qu'une telle serrure n'agit sur aucun verrou, mais est uniquement destinée à l'émission du signal de condamnation.For this purpose, the cabin is usually equipped with an additional lock which, when activated, sends a locking signal to the central control unit, according to which the cabin is locked. It should be noted that such a lock does not act on any lock, but is only intended for the transmission of the locking signal.

Ainsi, lorsqu'un membre de l'équipe technique souhaite condamner la cabine, il doit, d'une part, actionner lesdits autres moyens d'actionnement pour déplacer le verrou en position de verrouillage et, d'autre part, actionner la serrure supplémentaire pour émettre le signal de condamnation à destination de l'unité centrale de contrôle.Thus, when a member of the technical team wishes to condemn the cabin, it must, on the one hand, actuate said other actuating means to move the lock in the locking position and, on the other hand, actuate the additional lock to transmit the judgment signal to the central control unit.

En d'autres termes, ce membre de l'équipe technique doit actionner deux serrures distinctes pour passer proprement la cabine dans l'état condamné. Or, il n'existe aucune garantie que les deux serrures soient bien actionnées, ce qui peut entraîner des erreurs en cas d'oubli d'actionnement de l'une de ces serrures.In other words, this member of the technical team must operate two separate locks to cleanly pass the cabin in the condemned state. However, there is no guarantee that the two locks are actuated, which can lead to errors if you forget to operate one of these locks.

Par exemple, le verrou peut être en position déverrouillée alors que le signal de condamnation est émis.For example, the lock may be in the unlocked position while the judgment signal is issued.

En particulier, il est important qu'un utilisateur enfermé dans une cabine puisse en sortir à tout moment, notamment même lorsque la cabine est dans l'état condamné. Dans le cas du dispositif de verrouillage évoqué ci-dessus, l'utilisateur peut sortir de la cabine en actionnant le verrou vers sa position de déverrouillage, même lorsque la cabine est considérée comme condamnée, et que ladite serrure supplémentaire a été activée pour émettre le signal de condamnation. Dans ce cas, après que l'utilisateur soit sorti de la cabine, cette cabine se retrouve libre d'accès, alors qu'elle est considérée comme condamnée par l'équipe technique.In particular, it is important that a user locked in a cabin can leave at any time, especially when the cabin is in the condemned state. In the case of the locking device mentioned above, the user can exit the cabin by actuating the lock to its unlocking position, even when the cabin is considered as locked, and that said additional lock has been activated to issue the sentencing signal. In this case, after the user has left the cabin, this cabin is free to access, while it is considered condemned by the technical team.

On connait également, dans l'état de la technique, notamment d'après GB 2 275 733 , un dispositif de verrouillage similaire à celui du préambule de la revendication 1.It is also known in the state of the art, in particular according to GB 2,275,733 , a locking device similar to that of the preamble of claim 1.

L'invention a notamment pour but de remédier à l'inconvénient précité, en fournissant un dispositif de verrouillage permettant d'éviter les erreurs d'indication d'un état occupé ou condamné de la porte, notamment du fait de la présence d'un utilisateur dans la cabine en cas de condamnation de la porte.The object of the invention is in particular to remedy the aforementioned drawback by providing a locking device making it possible to avoid errors in indicating a busy or condemned state of the door, particularly because of the presence of a user in the cabin if the door is locked.

A cet effet, l'invention a notamment pour objet un dispositif de verrouillage selon la revendication 1.For this purpose, the subject of the invention is in particular a locking device according to claim 1.

Le dispositif de verrouillage selon l'invention est dans l'état condamné lorsque le loquet est dans sa première position. Ce loquet est passé dans cette première position au moyen desdits moyens mécaniques d'actionnement du loquet, qui sont indépendants de tout autre élément de verrouillage pouvant être actionné par un utilisateur, tel qu'un bouton de porte.The locking device according to the invention is in the condemned state when the latch is in its first position. This latch is passed into this first position by means of said mechanical means of actuating the latch, which are independent of any other locking element that can be actuated by a user, such as a door knob.

Lorsque le loquet est dans sa première position, la première gâche forme une butée pour le premier pêne. Or, ce premier pêne ne peut être actionné qu'au moyen de la poignée de porte intérieure, si bien qu'il n'est alors pas possible d'ouvrir la porte depuis l'extérieur. En revanche, un utilisateur enfermé dans la cabine peut en sortir en actionnant la poignée de porte intérieure, escamotant le premier pêne qui peut ainsi sortir de la première gâche, autorisant alors l'ouverture de la porte.When the latch is in its first position, the first striker forms a stop for the first bolt. However, this first bolt can be operated by means of the inner door handle, so that it is not possible to open the door from the outside. On the other hand, a user locked in the cabin can get out by operating the interior door handle, retracting the first bolt which can thus leave the first striker, then allowing the opening of the door.

Lorsque l'utilisateur sort de la cabine, il relâche la poignée de porte intérieure, si bien que le premier pêne revient dans sa position en saillie. Lorsque la porte est refermée, par exemple au moyen d'un ferme-porte automatique, ce premier pêne se retrouve logé dans la première gâche, si bien que la cabine reste inaccessible depuis l'extérieur.As the user exits the cabin, he releases the interior door handle, so that the first bolt returns to its projecting position. When the door is closed, for example by means of an automatic door closer, this first bolt is found housed in the first striker, so that the cabin remains inaccessible from the outside.

La cabine reste donc dans son état condamné, même si un utilisateur, qui était enfermé à l'intérieur, en sort.The cabin remains in its condemned state, even if a user, who was locked inside, leaves.

Un dispositif de verrouillage selon l'invention peut comporter en outre l'une ou plusieurs des caractéristiques suivantes, prises seules ou selon toutes combinaisons techniquement envisageables.

  • Les troisièmes moyens de déplacement du troisième pêne sont activables par la poignée de porte intérieure pour le passage du troisième pêne depuis sa position en saillie vers sa position escamotée.
  • Le dispositif de verrouillage comporte des troisièmes moyens de détection de la position du troisième pêne, et des troisièmes moyens d'émission d'un signal à une unité de contrôle lorsque les troisièmes moyens de détection détectent le troisième pêne dans sa position en saillie.
  • Le dispositif de verrouillage comporte une unité de contrôle, et des moyens d'affichage visuel, tels que : lorsque l'unité de contrôle reçoit un signal selon lequel le loquet est dans sa première position, alors les moyens d'affichage indiquent que la porte est condamnée, et lorsque l'unité de contrôle reçoit un signal selon lequel le troisième pêne est dans sa position en saillie, mais qu'elle ne reçoit pas de signal selon lequel le loquet est dans sa première position, alors les moyens d'affichage indiquent que la porte est verrouillée par un utilisateur.
  • Le dispositif de verrouillage comporte des moyens d'indication audio, tels que : lorsque l'unité de contrôle reçoit un signal selon lequel le second pêne est dans sa position escamotée, et que l'unité de contrôle reçoit un signal selon lequel le loquet est dans sa première position, alors les moyens d'indication audio émettent un message audio selon lequel la porte est condamnée, et lorsque l'unité de contrôle reçoit un signal selon lequel le second pêne est dans sa position escamotée, et que l'unité de contrôle reçoit un signal selon lequel le troisième pêne est dans sa position en saillie, mais qu'elle ne reçoit pas de signal selon lequel le loquet est dans sa première position, alors les moyens d'indication audio émettent un message audio selon lequel la porte est verrouillée par un utilisateur.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux figures annexées, parmi lesquelles :

  • la figure 1 est une vue d'une face extérieure d'une porte, équipée par un dispositif de verrouillage selon un exemple de mode de réalisation de l'invention ;
  • la figure 2 est un détail d'une partie du dispositif de verrouillage équipant la porte de la figure 1, représenté en arraché partiel et vu depuis le côté d'une face intérieure de la porte.
The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended figures, among which:
  • the figure 1 is a view of an outer face of a door, equipped with a locking device according to an exemplary embodiment of the invention;
  • the figure 2 is a detail of a part of the locking device equipping the door of the figure 1 , shown in partial snatch and seen from the side of an inner face of the door.

On a représenté, sur la figure 1, une porte 10, notamment une porte de cabine de toilette pour un véhicule ferroviaire.On the figure 1 , a door 10, in particular a toilet cabin door for a railway vehicle.

Cette porte 10 est portée par un bâti 12, dans lequel est agencé un cadre de porte 14 délimitant une ouverture de passage. La porte 10 est mobile de manière classique entre une position ouverte autorisant l'accès à la cabine à travers l'ouverture de passage, et une position fermée interdisant l'accès à la cabine en obturant l'ouverture de passage.This door 10 is carried by a frame 12, in which is arranged a door frame 14 defining a passage opening. The door 10 is movable conventionally between an open position allowing access to the cabin through the passage opening, and a closed position prohibiting access to the cabin by closing the passage opening.

La porte 10 présente une face extérieure 10A, représentée sur la figure 1, et une face intérieure 10B, visible partiellement sur la figure 2.The door 10 has an outer face 10A, shown on the figure 1 , and an inner face 10B, partially visible on the figure 2 .

La porte 10 est équipée d'un dispositif de verrouillage, désigné par la référence générale 16.The door 10 is equipped with a locking device, designated by the general reference 16.

Le dispositif de verrouillage 16 comporte une poignée de porte extérieure 18, agencée sur la face extérieure 10A de la porte 10, et une poignée de porte intérieure 20, agencée sur la face intérieure 10B de la porte 10. Ces poignées extérieure 18 et intérieure 20 permettent d'actionner différents pênes de porte qui vont être décrits ultérieurement.The locking device 16 comprises an outer door handle 18, arranged on the outer face 10A of the door 10, and an inner door handle 20, arranged on the inner face 10B of the door 10. These outer handles 18 and inner 20 allow to operate different door bolts that will be described later.

Le dispositif de verrouillage 16 comporte un premier pêne 22, porté par la porte 10, mobile entre une position en saillie et une position escamotée. Ce premier pêne 22 est par exemple de type pêne à demi-tour.The locking device 16 comprises a first bolt 22, carried by the door 10, movable between a projecting position and a retracted position. This first bolt 22 is for example of the type latch bolt.

Le premier pêne 22 est déplacé entre sa position en saillie et sa position escamotée par des premiers moyens de déplacement (non représentés). Ces premiers moyens de déplacement ne sont reliés qu'à la poignée de porte intérieure 20 parmi les poignées de porte intérieure 20 et extérieure 18. Ainsi, le premier pêne 22 ne peut passer dans sa position escamotée qu'en actionnant la poignée intérieure 20. L'actionnement de la poignée extérieure 18 n'a aucun effet sur ce premier pêne 22.The first bolt 22 is moved between its projecting position and its retracted position by first moving means (not shown). These first moving means are connected only to the inner door handle 20 among the inner and outer door handles 20. Thus, the first bolt 22 can only move into its retracted position by actuating the inner handle 20. The actuation of the outer handle 18 has no effect on this first bolt 22.

Les premiers moyens de déplacement comportent par ailleurs un élément élastique de rappel du premier pêne 22 vers sa position en saillie, par exemple un ressort.The first displacement means further comprise an elastic element for returning the first bolt 22 to its protruding position, for example a spring.

Ces premiers moyens de déplacement sont de type classique, et ne seront donc pas décrits plus en détail.These first moving means are of conventional type, and will therefore not be described in more detail.

Le dispositif de verrouillage 16 comporte par ailleurs une première gâche 24, de type amovible, destinée à être portée par le bâti 12, notamment par le cadre de porte 14. La première gâche 24 comporte une partie mobile 26, mobile en basculement autour d'un axe de basculement, indépendamment de la position du premier pêne 22. La première gâche 24 est agencée en regard du premier pêne 22, de sorte que ce premier pêne 22 est logé dans cette première gâche 24 lorsqu'il est dans sa position en saillie.The locking device 16 also comprises a first striker 24, of removable type, intended to be carried by the frame 12, in particular by the door frame 14. The first striker 24 comprises a movable part 26, movable in tilting around a pivot axis, independently of the position of the first bolt 22. The first striker 24 is arranged opposite the first bolt 22, so that the first bolt 22 is housed in the first latch 24 when in its projecting position. .

Avantageusement, le dispositif de verrouillage 16 comporte des moyens électroniques (non représentés) de contrôle de la première gâche amovible 24, commutables entre une configuration de condamnation, dans laquelle ladite partie mobile 26 est immobilisée, et une configuration de libération, dans laquelle la partie mobile 26 est libre de basculer autour de son axe de basculement. De tels moyens électroniques de contrôle sont classiques et ne seront donc pas décrits davantage.Advantageously, the locking device 16 comprises electronic means (not shown) for controlling the first removable striker 24, switchable between a locking configuration, in which said movable portion 26 is immobilized, and a release configuration, in which the portion mobile 26 is free to switch around its axis of tilting. Such electronic control means are conventional and will not be described further.

Lorsque la partie mobile 26 est immobilisée, elle forme une butée pour le premier pêne 22 en position en saillie, s'opposant ainsi à l'ouverture de la porte. Il est alors nécessaire de passer le pêne 22 dans sa position escamotée, en actionnant la poignée intérieure 20, pour le libérer de la première gâche 24, et ainsi autoriser l'ouverture de la porte. Dans ce cas, puisque la poignée extérieure 18 ne permet pas d'actionner le premier pêne 22, il est impossible pour un utilisateur d'ouvrir la porte depuis l'extérieur.When the movable portion 26 is immobilized, it forms a stop for the first bolt 22 in projecting position, thus opposing the opening of the door. It is then necessary to pass the bolt 22 in its retracted position, by actuating the inner handle 20, to release it from the first striker 24, and thus allow the opening of the door. In this case, since the outer handle 18 does not operate the first bolt 22, it is impossible for a user to open the door from the outside.

En revanche, lorsque la partie mobile 26 est libre, elle ne forme pas d'obstacle pour le premier pêne 22 en position en saillie lors de l'ouverture de la porte 10. Le premier pêne 22 et la première gâche 24 ne s'opposent ainsi pas à l'ouverture de la porte par un utilisateur depuis l'extérieur de la cabine.On the other hand, when the mobile part 26 is free, it does not form an obstacle for the first bolt 22 in projecting position when the door 10 is opened. The first bolt 22 and the first striker 24 do not oppose each other. thus not at the opening of the door by a user from outside the cabin.

Ces premiers moyens électroniques de contrôle sont activables de manière automatique. A cet effet, le dispositif de verrouillage comporte des moyens de détection d'une anomalie de fonctionnement de la cabine de toilette (par exemple liée aux arrivées et évacuations d'eau), de manière à commuter les moyens de contrôle en configuration de condamnation en cas de détection d'une anomalie. En d'autres termes, lorsqu'une anomalie est détectée, la cabine de toilette est passée automatiquement en état condamné.These first electronic control means can be activated automatically. For this purpose, the locking device comprises means for detecting an abnormality of operation of the toilet cabin (for example related to arrivals and discharges of water), so as to switch the control means in locking configuration in case of detection of an anomaly. In other words, when an anomaly is detected, the washroom is automatically placed in condemned state.

Le dispositif de verrouillage 16 selon l'invention comporte par ailleurs un loquet 28, porté par le bâti 12, mobile entre une première position (désignée par la référence 28A sur la figure 2), dans laquelle ce loquet 28 coopère avec la partie mobile 26 pour la maintenir immobilisée, de sorte qu'elle forme une butée pour le premier pêne 22 en position en saillie, et une seconde position (désignée par la référence 28B sur la figure 2), dans laquelle le loquet est maintenu à l'écart de la partie mobile 26, pour autoriser son libre basculement autour de son axe de basculement, de sorte qu'elle ne forme ainsi pas d'obstacle pour le premier pêne 22 en position en saillie lors de l'ouverture de la porte 10.The locking device 16 according to the invention further comprises a latch 28, carried by the frame 12, movable between a first position (designated by the reference 28A on the figure 2 ), wherein the latch 28 cooperates with the movable portion 26 to keep it stationary, so that it forms a stop for the first bolt 22 in projecting position, and a second position (designated by the reference 28B on the figure 2 ) wherein the latch is held away from the movable portion 26, to allow its free tilting about its tilt axis, so that it does not form an obstacle for the first bolt 22 in projecting position when the opening of the door 10.

Le loquet 28 est par exemple mobile en rotation autour d'un pivot 29 entre ses première 28A et seconde 28B positions. En variante, le loquet 28 pourrait être mobile en translation.The latch 28 is for example rotatable about a pivot 29 between its first 28A and second 28B positions. Alternatively, the latch 28 could be movable in translation.

Le loquet 28 est déplacé entre ses première 28A et seconde 28B positions par des premiers moyens mécaniques d'actionnement 30, accessibles depuis la face extérieure de la porte 10. Ces premiers moyens mécaniques d'actionnement 30 sont généralement agencés sur le bâti 12, en regard du pivot 29 autour duquel le loquet 28 est mobile en rotation.The latch 28 is moved between its first 28A and second 28B positions by first mechanical actuating means 30, accessible from the outer face of the door 10. These first mechanical actuating means 30 are generally arranged on the frame 12, in view of the pivot 29 around which the latch 28 is movable in rotation.

Ces premiers moyens d'actionnement du loquet 30 comportent une forme d'engagement, accessible depuis l'extérieur de la cabine, solidaire en rotation du loquet 28. Cette forme d'engagement est destinée à coopérer avec un élément d'actionnement complémentaire (non représenté), notamment une clé. En d'autres termes, cette forme d'engagement présente une forme susceptible d'être entraînée en rotation par cet élément d'actionnement.These first actuating means of the latch 30 comprise a form of engagement, accessible from outside the cabin, integral in rotation with the latch 28. This form of engagement is intended to cooperate with a complementary actuating element (not represented), including a key. In other words, this form of engagement has a shape that can be rotated by this actuating element.

La forme d'engagement forme par exemple une partie mâle, et l'élément d'actionnement comporte alors une partie cylindrique munie d'un orifice complémentaire formant une partie femelle. Ainsi, l'élément d'actionnement permet de manipuler la rotation du loquet 28 lorsqu'il est engagé sur la forme d'engagement.The form of engagement forms for example a male part, and the actuating element then comprises a cylindrical portion provided with a complementary hole forming a female part. Thus, the actuating element makes it possible to manipulate the rotation of the latch 28 when it is engaged on the engagement form.

Par exemple, la forme d'engagement présente une section carrée, mais toute autre forme permettant un entraînement en rotation de la forme d'engagement par l'élément d'actionnement est envisageable en variante.For example, the form of engagement has a square section, but any other form allowing a drive in rotation of the engagement form by the actuating element is alternatively feasible.

Ainsi, il apparaît qu'un membre d'une équipe technique, muni de l'élément d'actionnement, peut faire basculer le loquet dans sa première position, passant ainsi la cabine dans l'état condamné.Thus, it appears that a member of a technical team, provided with the actuating element, can tilt the latch in its first position, thus passing the cabin in the condemned state.

Le dispositif de verrouillage 16 comporte par ailleurs des premiers moyens 32 de détection de la position du loquet 28. Ces premiers moyens de détection 32 comportent par exemple un interrupteur, porté par le bâti 12, comportant un poussoir 34, mobile entre une position haute et une position basse. Ce poussoir 34 est agencé à proximité du loquet 28, de sorte que ce loquet 28 dans sa première position 28A coopère avec le poussoir 34 en le passant dans sa position basse.The locking device 16 also comprises first means 32 for detecting the position of the latch 28. These first detection means 32 comprise, for example, a switch, carried by the frame 12, comprising a pusher 34, movable between a high position and a low position. This pusher 34 is arranged near the latch 28, so that the latch 28 in its first position 28A cooperates with the pusher 34 by passing it in its lower position.

Les premiers moyens de détection 32 sont connectés à des premiers moyens d'émission d'un signal à une unité de contrôle 36, propres à envoyer un signal relatif à la position du loquet 28 détectée par ces premiers moyens de détection 32.The first detection means 32 are connected to first means for transmitting a signal to a control unit 36, able to send a signal relating to the position of the latch 28 detected by these first detection means 32.

Par exemple, ces premiers moyens d'émission émettent un signal selon lequel la porte est condamnée lorsque les premiers moyens de détection 32 détectent le loquet 28 dans sa première position 28A, c'est-à-dire lorsque le poussoir 34 est dans sa position basse.For example, these first transmission means emit a signal according to which the door is locked when the first detection means 32 detect the latch 28 in its first position 28A, that is to say when the pusher 34 is in its position low.

Avantageusement, les premiers moyens d'émission sont également connectés auxdits moyens électroniques de contrôle, afin d'envoyer à l'unité de contrôle 36 un signal selon lequel la porte 10 est dans l'état condamné lorsque les moyens électroniques de contrôle sont en configuration de condamnation.Advantageously, the first transmission means are also connected to said electronic control means, in order to send to the control unit 36 a signal according to which the gate 10 is in the condemned state when the electronic control means are in configuration of conviction.

De préférence, le signal émis porte une information différente dans le cas où la partie mobile 26 de la gâche 24 est immobilisée automatiquement et dans le cas où cette partie mobile 26 est immobilisée mécaniquement par le loquet 28. Ainsi, l'unité de contrôle 36 peut distinguer le cas où la condamnation est manuelle, par l'intermédiaire du loquet 28, ou lorsqu'elle est automatique, par l'intermédiaire des moyens électroniques de contrôle.Preferably, the transmitted signal carries a different information in the case where the movable portion 26 of the striker 24 is immobilized automatically and in the case where the movable portion 26 is mechanically immobilized by the latch 28. Thus, the control unit 36 can distinguish the case where the conviction is manual, through the latch 28, or when it is automatic, through the electronic control means.

Le dispositif de verrouillage 16 comporte par ailleurs un second pêne 37, porté par la porte 10, mobile entre une position en saillie et une position escamotée. Ce second pêne 37 est par exemple de type pêne à demi-tour.The locking device 16 further comprises a second bolt 37, carried by the door 10, movable between a projecting position and a retracted position. This second bolt 37 is for example of the type latch bolt.

Le second pêne 37 est déplacé entre sa position en saillie et sa position escamotée par des seconds moyens de déplacement (non représentés). Ces seconds moyens de déplacement sont reliés à la poignée de porte intérieure 20 et à la poignée de porte extérieure 18. Ainsi, le second pêne 37 peut passer dans sa position escamotée en actionnant l'une ou l'autre des poignées intérieure 20 et extérieure 18.The second bolt 37 is moved between its projecting position and its retracted position by second displacement means (not shown). These second moving means are connected to the inner door handle 20 and to the outer door handle 18. Thus, the second bolt 37 can pass into its retracted position by actuating one or other of the inner and outer handles 20 18.

Les seconds moyens de déplacement comportent par ailleurs un élément élastique de rappel du second pêne 37 vers sa position en saillie, par exemple un ressort.The second displacement means further comprise an elastic return element of the second bolt 37 to its protruding position, for example a spring.

Ces seconds moyens de déplacement sont de type classique, et ne seront donc pas décrits plus en détail.These second moving means are of conventional type, and will not be described in more detail.

Le second pêne 37 coopère avec une seconde gâche fixe 38 de type classique ménagée dans le bâti 12, notamment dans le cadre de porte 14. La seconde gâche 38 est agencée en regard du second pêne 37, de sorte que ce second pêne 37 est logé dans cette seconde gâche 38 lorsqu'il est dans sa position en saillie. Ainsi, le second pêne 37 vient en butée contre un bord de la seconde gâche 38 lorsqu'il est en position en saillie, empêchant l'ouverture de la porte 10. En revanche, lorsque le second pêne 37 est dans sa position escamotée, il sort de la seconde gâche 38, et ne s'oppose donc pas à l'ouverture de la porte 10.The second bolt 37 cooperates with a second fixed keeper 38 of conventional type formed in the frame 12, in particular in the door frame 14. The second striker 38 is arranged facing the second bolt 37, so that the second latch 37 is housed in this second striker 38 when in its projecting position. Thus, the second bolt 37 abuts against an edge of the second striker 38 when it is in projecting position, preventing the opening of the door 10. On the other hand, when the second bolt 37 is in its retracted position, it leaves the second striker 38, and therefore does not oppose the opening of the door 10.

Le dispositif de verrouillage 16 comporte des seconds moyens 40 de détection de la position du second pêne 37. Ces seconds moyens de détection 40, de type classique, sont connectés à des seconds moyens d'émission d'un signal, relatif à la position du second pêne 37, à l'unité de contrôle 36. Plus particulièrement, les seconds moyens d'émission émettent un signal lorsque les seconds moyens de détection 40 détectent le second pêne 37 dans sa position escamotée.The locking device 16 comprises second means 40 for detecting the position of the second bolt 37. These second detection means 40, of conventional type, are connected to second means for transmitting a signal, relative to the position of the second bolt 37, to the control unit 36. More particularly, the second transmission means emit a signal when the second detection means 40 detect the second bolt 37 in its retracted position.

Le dispositif de verrouillage 16 comporte enfin un troisième pêne 42, de type pêne dormant, porté par la porte 10, également mobile entre une position en saillie et une position escamotée dans la porte 10.The locking device 16 finally comprises a third bolt 42, of deadbolt type, carried by the door 10, also movable between a projecting position and a retracted position in the door 10.

Le troisième pêne 42 est déplacé entre sa position en saillie et sa position escamotée par des troisièmes moyens de déplacement (non représentés). Ces troisièmes moyens de déplacement sont reliés à un élément d'actionnement 44, par exemple un bouton de porte, porté par la porte 10 sur sa face intérieure 10B.The third bolt 42 is moved between its projecting position and its retracted position by third moving means (not shown). These third moving means are connected to an actuating element 44, for example a door knob, carried by the door 10 on its inner face 10B.

Avantageusement, les troisièmes moyens de déplacement sont également reliés à la poignée de porte intérieure 20 pour le passage du troisième pêne 42 depuis sa position en saillie vers sa position escamotée.Advantageously, the third moving means are also connected to the inner door handle 20 for the passage of the third bolt 42 from its projecting position to its retracted position.

Ainsi, l'actionnement de la poignée intérieure 20 permet de passer chacun des premier 22, deuxième 37 et troisième 42 pênes dans leur position respective escamotée, et permet donc d'ouvrir la porte 10 depuis l'intérieur de la cabine dans tous les cas.Thus, the actuation of the inner handle 20 makes it possible to pass each of the first 22, second 37 and third 42 bolts in their respective retracted position, and thus allows the door 10 to be opened from inside the cabin in all cases .

Les troisièmes moyens de déplacement sont de type classique, et ne seront donc pas décrits plus en détail.The third moving means are of conventional type, and will not be described in more detail.

Le dispositif de verrouillage 16 comporte une troisième gâche fixe 46 de type classique, destinée à coopérer avec le troisième pêne 42. La troisième gâche 46 est agencée en regard du troisième pêne 42, de sorte que ce troisième pêne 42 est logé dans cette troisième gâche 46 lorsqu'il est dans sa position en saillie. Ainsi, le troisième pêne 42 vient en butée contre un bord de la troisième gâche 46 lorsqu'il est en position en saillie, empêchant l'ouverture de la porte 10. En revanche, lorsque le troisième pêne 42 est dans sa position escamotée, il sort de la troisième gâche 46, et ne s'oppose donc pas à l'ouverture de la porte 10.The locking device 16 comprises a third fixed striker 46 of conventional type, intended to cooperate with the third bolt 42. The third latch 46 is arranged opposite the third bolt 42, so that the third latch 42 is housed in this third latch 46 when in its protruding position. Thus, the third bolt 42 abuts against an edge of the third striker 46 when it is in projecting position, preventing the opening of the door 10. On the other hand, when the third bolt 42 is in its retracted position, it out of the third striker 46, and does not oppose the opening of the door 10.

En outre, le dispositif de verrouillage 16 comporte des troisièmes moyens 48 de détection de la position du troisième pêne 42, connectés à des troisièmes moyens d'émission d'un signal, relatif à la position détectée du troisième pêne 42, à l'unité de contrôle 36. Plus particulièrement, un signal est émis lorsque les troisièmes moyens de détection 48 détectent le troisième pêne 42 dans sa position en saillie.In addition, the locking device 16 comprises third means 48 for detecting the position of the third bolt 42, connected to third means for transmitting a signal, relating to the detected position of the third bolt 42, to the unit In particular, a signal is emitted when the third detection means 48 detect the third bolt 42 in its projecting position.

Il est à noter que le loquet 28, les moyens électroniques de contrôle, les différentes gâches et les différents moyens de détection sont habituellement masqués depuis l'intérieur de la cabine par un panneau (non représenté sur la figure 2).It should be noted that the latch 28, the electronic control means, the different strikes and the different detection means are usually masked from inside the cabin by a panel (not shown on the diagram). figure 2 ).

Avantageusement, le dispositif de verrouillage 16 comporte des seconds moyens 54 mécaniques d'actionnement de la poignée de porte intérieure 20 depuis l'extérieur de la cabine. Ces seconds moyens d'actionnement 54 comportent une forme d'engagement reliée aux mêmes moyens de déplacement de pênes que la poignée intérieure 20, par exemple liée en rotation à la poignée intérieure 20. Cette forme d'engagement est destinée à coopérer avec un élément d'actionnement complémentaire, formant une clé, et présente donc une forme susceptible d'être entraînée en rotation par un tel élément d'actionnement. Cet élément d'actionnement est généralement le même que celui utilisé pour activer les premiers moyens mécaniques d'actionnement du loquet 30.Advantageously, the locking device 16 comprises second mechanical means 54 for actuating the inner door handle 20 from outside the cabin. These second actuating means 54 comprise a form of engagement connected to the same bolt moving means as the inner handle 20, for example rotatably connected to the inner handle 20. This form of engagement is intended to cooperate with an element complementary actuation, forming a key, and therefore has a shape that can be rotated by such an actuating element. This actuating element is generally the same as that used to activate the first mechanical means for actuating the latch 30.

Ces seconds moyens d'actionnement 54 permettent à un membre de l'équipe technique d'accéder à la cabine, que celle-ci soit dans son état occupé ou condamné, par exemple en vue de porter secours à un utilisateur enfermé dans cette cabine.These second actuating means 54 allow a member of the technical team to access the cabin, whether it is in its occupied or condemned state, for example to assist a user locked in this cabin.

Le dispositif de verrouillage 16 comporte des moyens d'affichage visuel 50, destinés à afficher une indication visuelle relative à l'état libre, occupé ou condamné de la cabine. En effet, il est important pour les utilisateurs de connaître l'état de la cabine, notamment afin de savoir si elle est accessible (état libre), si elle sera libérée prochainement (état occupé), ou si elle restera inaccessible (état condamné). L'unité de contrôle 36 est propre à déterminer l'état de la cabine, en fonction des positions du loquet 28 et du troisième pêne 42, comme cela sera décrit ultérieurement.The locking device 16 comprises visual display means 50 intended to display a visual indication relating to the free, occupied or condemned state of the cabin. Indeed, it is important for the users to know the state of the cabin, in particular in order to know if it is accessible (free state), if it will be released soon (busy state), or if it will remain inaccessible (condemned state) . The control unit 36 is able to determine the state of the cabin, depending on the positions of the latch 28 and the third latch 42, as will be described later.

Par ailleurs, le dispositif de verrouillage 16 comporte avantageusement des moyens 52 d'indication audio, susceptibles d'indiquer par un message audio quel est l'état de la cabine. Par exemple, un message audio est délivré lorsque les seconds moyens de détection détectent que le second pêne 37 est dans sa position escamotée, ce qui signifie qu'une poignée de porte 18, 20 est actionnée. Ces messages audio permettent à un utilisateur mal voyant de connaître l'état de la cabine.Furthermore, the locking device 16 advantageously comprises means 52 audio indication, may indicate by an audio message what is the state of the cabin. For example, an audio message is delivered when the second detecting means detects that the second latch 37 is in its retracted position, which means that a door handle 18, 20 is actuated. These audio messages allow a visually impaired user to know the status of the booth.

Le fonctionnement du dispositif de verrouillage 16 sera décrit ci-dessous.The operation of the locking device 16 will be described below.

La cabine est dans l'état libre lorsque :

  • le loquet 28 est dans sa seconde position 28B,
  • les moyens électroniques de contrôle sont dans leur configuration de libération,
  • le second pêne 37 est dans sa position en saillie, et
  • le troisième pêne 42 est dans sa position escamotée.
The cabin is in the free state when:
  • the latch 28 is in its second position 28B,
  • the electronic control means are in their release configuration,
  • the second bolt 37 is in its projecting position, and
  • the third bolt 42 is in its retracted position.

Le premier pêne 22 est également dans sa position en saillie, mais il n'entrave pas l'ouverture de la porte 10 puisque la partie mobile 26 de la première gâche 24 n'est pas immobilisée par le loquet 28 ou par les moyens électroniques de contrôle.The first bolt 22 is also in its projecting position, but it does not hinder the opening of the door 10 since the movable portion 26 of the first striker 24 is not immobilized by the latch 28 or by the electronic means of control.

En l'absence de réception d'un signal selon lequel le loquet 28 est dans sa première position 28A (ou, en variante, en présence de réception d'un signal selon lequel le loquet est dans sa seconde position 28B) et en l'absence de réception d'un signal selon lequel les moyens électroniques de contrôle sont dans leur configuration de condamnation (ou en variante en présence d'un signal selon lequel les moyens électroniques de contrôle sont dans leur configuration de libération), l'unité de contrôle 36 déduit que la cabine n'est pas en état condamné.In the absence of reception of a signal according to which the latch 28 is in its first position 28A (or, alternatively, in the presence of receiving a signal according to which the latch is in its second position 28B) and in the absence of receiving a signal according to which the electronic control means are in their locking configuration (or alternatively in the presence of a signal according to which the electronic control means are in their release configuration), the control unit 36 deduces that the cabin is not in a condemned state.

Alors, en l'absence de réception d'un signal selon lequel le troisième pêne 42 est dans sa position en saillie (ou, en variante, en présence d'un signal selon lequel le troisième pêne 42 est dans sa position escamotée), l'unité de contrôle 36 déduit que la cabine est dans l'état libre.Then, in the absence of reception of a signal according to which the third bolt 42 is in its projecting position (or, alternatively, in the presence of a signal according to which the third bolt 42 is in its retracted position), the control unit 36 deduces that the cabin is in the free state.

Les moyens d'affichage 50 affichent donc que la cabine est dans son état libre.The display means 50 thus display that the cabin is in its free state.

Lorsque la poignée extérieure 18 est actionnée, l'unité de contrôle 36 reçoit un signal selon lequel le second pêne 37 est dans sa position escamotée, et les moyens d'indication audio 52 émettent alors un message audio selon lequel la cabine est en état libre.When the outer handle 18 is actuated, the control unit 36 receives a signal according to which the second bolt 37 is in its retracted position, and the audio indication means 52 then emit an audio message according to which the cabin is in a free state .

En variante, dans l'état libre, les moyens d'indication audio 52 n'émettent aucun message audio, puisqu'une simple activation de la poignée extérieure 18 permet de savoir que la porte peut s'ouvrir, ce qui correspond dans tous les cas à un état libre.Alternatively, in the free state, the audio indication means 52 emit no audio message, since a simple activation of the outer handle 18 makes it possible to know that the door can open, which corresponds in all case to a free state.

Une fois l'utilisateur à l'intérieur de la cabine, il referme la porte, si bien que le second pêne 37 revient dans sa position en saillie, et il actionne l'élément d'actionnement 44 pour verrouiller la porte.Once the user inside the cabin, it closes the door, so that the second bolt 37 returns to its projecting position, and it actuates the actuating element 44 to lock the door.

La cabine est dans l'état occupé lorsque :

  • le loquet 28 est dans sa seconde position 28B,
  • les moyens électroniques de contrôle sont dans leur configuration de libération,
  • le second pêne 37 est dans sa position en saillie, et
  • le troisième pêne 42 est dans sa position en saillie.
The cabin is in the occupied state when:
  • the latch 28 is in its second position 28B,
  • the electronic control means are in their release configuration,
  • the second bolt 37 is in its projecting position, and
  • the third bolt 42 is in its projecting position.

Le premier pêne 22 est également dans sa position en saillie, mais il n'entrave pas l'ouverture de la porte 10 puisque la partie mobile 26 de la première gâche 24 n'est pas immobilisée par le loquet 28 ou les moyens électroniques de contrôle.The first bolt 22 is also in its projecting position, but it does not hinder the opening of the door 10 since the movable portion 26 of the first striker 24 is not immobilized by the latch 28 or the electronic control means .

Comme précédemment, l'unité de contrôle 36 déduit que la cabine n'est pas en état condamné.As before, the control unit 36 deduces that the cabin is not in a condemned state.

Alors, à la réception d'un signal selon lequel le troisième pêne 42 est dans sa position en saillie (ou, en variante, en l'absence d'un signal selon lequel le troisième pêne 42 est dans sa position escamotée), l'unité de contrôle 36 déduit que la cabine est dans l'état occupé.Then, on receiving a signal according to which the third bolt 42 is in its projecting position (or, alternatively, in the absence of a signal according to which the third bolt 42 is in its retracted position), the control unit 36 deduces that the cabin is in the busy state.

Les moyens d'affichage 50 affichent donc que la cabine est dans son état occupé.The display means 50 thus display that the cabin is in its busy state.

Si la poignée extérieure 18 est actionnée, l'unité de contrôle 36 reçoit un signal selon lequel le second pêne 37 est dans sa position escamotée, et les moyens d'indication audio 52 émettent alors un message audio selon lequel la cabine est dans l'état occupé.If the outer handle 18 is actuated, the control unit 36 receives a signal that the second latch 37 is in its retracted position, and the audio indication means 52 then emits an audio message that the car is in the same position. busy state.

En variante, les moyens d'indication audio 52 n'émettent aucun message si c'est la poignée intérieure 20 qui est actionnée. L'unité de contrôle 36 déduit que c'est la poignée intérieure 20 est actionnée lorsque le second pêne 37 et le troisième pêne 42 passent tous deux dans leur position escamotée, alors que le troisième pêne 42 était dans sa position en saillie.Alternatively, the audio indication means 52 emit no message if it is the inner handle 20 is actuated. The control unit 36 deduces that it is the inner handle 20 is actuated when the second bolt 37 and the third bolt 42 both pass into their retracted position, while the third bolt 42 was in its projecting position.

En cas d'anomalie détectée, les moyens automatiques de contrôle immobilisent la partie mobile 26 de la première gâche 24. Dans ce cas :

  • le loquet 28 est dans sa seconde position 28B,
  • les moyens électroniques de contrôle sont dans leur configuration de condamnation,
  • le second pêne 37 est dans sa position en saillie, et
  • le troisième pêne 42 est dans sa position en saillie si un utilisateur est enfermé dans la cabine, et en position escamotée dans le cas contraire.
In the event of an anomaly detected, the automatic control means immobilize the moving part 26 of the first striker 24. In this case:
  • the latch 28 is in its second position 28B,
  • the electronic control means are in their condemnation configuration,
  • the second bolt 37 is in its projecting position, and
  • the third bolt 42 is in its protruding position if a user is locked in the cabin, and in the retracted position in the opposite case.

Le premier pêne 22 est dans sa position en saillie, coopérant avec la première gâche 24 dont la partie mobile 26 est immobilisée, interdisant ainsi l'ouverture de la porte 10 depuis l'extérieur par un utilisateur, puisque la poignée extérieure 18 ne permet pas d'agit sur ce premier pêne 22.The first bolt 22 is in its projecting position, cooperating with the first striker 24 whose movable portion 26 is immobilized, thus preventing the door 10 from being opened from the outside by a user, since the external handle 18 does not allow act on this first bolt 22.

A la réception d'un signal selon lequel les moyens électroniques de contrôle sont dans leur configuration de condamnation (ou en variante en l'absence de signal selon lequel les moyens électroniques de contrôle sont dans leur configuration de libération), l'unité de contrôle 36 déduit que la cabine est en état condamné, et cela quelle que soit la position du troisième pêne 42.On receipt of a signal according to which the electronic control means are in their locking configuration (or alternatively in the absence of a signal according to which the electronic control means are in their release configuration), the control unit 36 infers that the cabin is in a condemned state, regardless of the position of the third bolt.

Les moyens d'affichage 50 affichent donc que la cabine est dans son état condamné.The display means 50 thus display that the cabin is in its condemned state.

Si la poignée extérieure 18 est actionnée, l'unité de contrôle 36 reçoit un signal selon lequel le second pêne 37 est dans sa position escamotée, et les moyens d'indication audio 52 émettent alors un message audio selon lequel la cabine est en état condamné.If the external handle 18 is actuated, the control unit 36 receives a signal according to which the second bolt 37 is in its retracted position, and the audio indication means 52 then emit an audio message according to which the cabin is in a condemned state. .

En variante, les moyens d'indication audio 52 n'émettent aucun message si c'est la poignée intérieure 20 qui est actionnée. L'unité de contrôle 36 déduit que c'est la poignée intérieure 20 est actionnée lorsque le second pêne 37 et le troisième pêne 42 passent tous deux dans leur position escamotée, alors que le troisième pêne 42 était dans sa position en saillie.Alternatively, the audio indication means 52 emit no message if it is the inner handle 20 is actuated. The control unit 36 deduces that it is the inner handle 20 is actuated when the second bolt 37 and the third latch 42 both pass into their retracted position, while the third bolt 42 was in its projecting position.

Si un utilisateur était dans la cabine lors de sa condamnation, il peut en sortir en actionnant la poignée intérieure 20, qui agit sur chacun des premier 22, second 37 et troisième 42 pênes, qui passent tous dans leur position escamotée, sortant de leur gâche respective, autorisant ainsi l'ouverture de la porte.If a user was in the cabin during his conviction, he can get out by operating the inner handle 20, which acts on each of the first 22, second 37 and third 42 bolts, all of which pass into their retracted position, out of their latch respective, thereby allowing the door to open.

Cet actionnement de la poignée intérieure 20 n'a pas d'effet sur les moyens automatiques de contrôle, si bien que la cabine reste en état condamné. Lorsque la porte se referme, le premier pêne 22 revient dans sa position en saillie dans la première gâche 24, si bien que la porte 10 ne peut toujours pas être ouverte depuis l'extérieur par un utilisateur.This actuation of the inner handle 20 has no effect on the automatic control means, so that the cabin remains in a condemned state. When the door closes, the first bolt 22 returns to its projecting position in the first striker 24, so that the door 10 can still not be opened from the outside by a user.

Un membre de l'équipe technique peut en revanche ouvrir la porte grâce aux seconds moyens d'actionnement 54, qui ont le même effet que l'actionnement de la poignée intérieure 20, comme décrit précédemment.A member of the technical team may however open the door with the second actuating means 54, which have the same effect as the actuation of the inner handle 20, as described above.

La cabine peut également être passée dans l'état condamné par un membre de l'équipe technique, qui actionne à cet effet les premiers moyens d'actionnement 30. Dans ce cas, le loquet 28 vient immobiliser la partie mobile 26 de la première gâche 24, si bien que :

  • le loquet 28 est dans sa première position 28A,
  • les moyens électroniques de contrôle sont dans leur configuration de libération (ou de condamnation),
  • le second pêne 37 est dans sa position en saillie, et
  • le troisième pêne 42 est dans sa position en saillie si un utilisateur est enfermé dans la cabine, et en position escamotée dans le cas contraire.
The cabin can also be passed in the condemned state by a member of the technical team, which actuates for this purpose the first actuating means 30. In this case, the latch 28 immobilizes the moving part 26 of the first strike 24, so that:
  • the latch 28 is in its first position 28A,
  • the electronic control means are in their release (or condemnation) configuration,
  • the second bolt 37 is in its projecting position, and
  • the third bolt 42 is in its protruding position if a user is locked in the cabin, and in the retracted position in the opposite case.

Le premier pêne 22 est dans sa position en saillie, coopérant avec la première gâche 24 dont la partie mobile 26 est immobilisée, interdisant ainsi l'ouverture de la porte 10 depuis l'extérieur par un utilisateur, puisque la poignée extérieure 18 ne permet pas d'agit sur ce premier pêne 22.The first bolt 22 is in its projecting position, cooperating with the first striker 24 whose movable portion 26 is immobilized, thus preventing the door 10 from being opened from the outside by a user, since the external handle 18 does not allow act on this first bolt 22.

A la réception d'un signal selon lequel le loquet est dans sa première position 28A (ou en variante en l'absence de signal selon lequel le loquet est dans sa seconde position 28B), l'unité de contrôle 36 déduit que la cabine est en état condamné, et cela quelle que soit la position du troisième pêne 42.Upon receipt of a signal that the latch is in its first position 28A (or alternatively in the absence of a signal that the latch is in its second position 28B), the control unit 36 deduces that the cab is in a condemned state, regardless of the position of the third bolt 42.

Les moyens d'affichage 50 affichent donc que la cabine est dans son état condamné.The display means 50 thus display that the cabin is in its condemned state.

Si la poignée extérieure 18 est actionnée, l'unité de contrôle 36 reçoit un signal selon lequel le second pêne 37 est dans sa position escamotée, et les moyens d'indication audio 52 émettent alors un message audio selon lequel la cabine est en état condamné.If the outer handle 18 is actuated, the control unit 36 receives a signal according to which the second bolt 37 is in its retracted position, and the means audio indication 52 then issue an audio message according to which the cabin is in condemned state.

En variante, les moyens d'indication audio 52 n'émettent aucun message si c'est la poignée intérieure 20 qui est actionnée. L'unité de contrôle 36 déduit que c'est la poignée intérieure 20 est actionnée lorsque le second pêne 37 et le troisième pêne 42 passent tous deux dans leur position escamotée, alors que le troisième pêne 42 était dans sa position en saillie.Alternatively, the audio indication means 52 emit no message if it is the inner handle 20 is actuated. The control unit 36 deduces that it is the inner handle 20 is actuated when the second bolt 37 and the third bolt 42 both pass into their retracted position, while the third bolt 42 was in its projecting position.

Si un utilisateur était dans la cabine lors de sa condamnation, il peut en sortir en actionnant la poignée intérieure 20, qui agit sur chacun des premier 22, second 37 et troisième 42 pênes, qui passent tous dans leur position escamotée, sortant de leur gâche respective, autorisant ainsi l'ouverture de la porte.If a user was in the cabin during his conviction, he can get out by operating the inner handle 20, which acts on each of the first 22, second 37 and third 42 bolts, all of which pass into their retracted position, out of their latch respective, thereby allowing the door to open.

Cet actionnement de la poignée intérieure 20 n'a pas d'effet sur la position du loquet 28, si bien que la cabine reste en état condamné. Lorsque la porte se referme, le premier pêne 22 revient dans sa position en saillie dans la première gâche 24, si bien que la porte 10 ne peut toujours pas être ouverte depuis l'extérieur par un utilisateur.This actuation of the inner handle 20 has no effect on the position of the latch 28, so that the cabin remains in a condemned state. When the door closes, the first bolt 22 returns to its projecting position in the first striker 24, so that the door 10 can still not be opened from the outside by a user.

Un membre de l'équipe technique peut en revanche ouvrir la porte grâce aux moyens d'actionnement 54, qui ont le même effet que l'actionnement de la poignée intérieure 20, comme décrit ci-dessus.A member of the technical team can however open the door through the actuating means 54, which have the same effect as the actuation of the inner handle 20, as described above.

On notera que l'invention n'est pas limitée au mode de réalisation précédemment décrit, mais pourrait présenter diverses variantes.Note that the invention is not limited to the embodiment described above, but could have various variants.

Par exemple, les moyens automatiques de contrôle pourraient en variante agir sur la position du loquet 28.For example, the automatic control means could alternatively act on the position of the latch 28.

Conformément à une autre variante, la position du loquet 28 pourrait agir sur la configuration des moyens automatiques de contrôle.According to another variant, the position of the latch 28 could act on the configuration of the automatic control means.
