Description

La présente invention concerne un système de verrouillage d'une porte d'accès à un espace, notamment des toilettes d'un véhicule ferroviaire, la porte fermée s'étendant dans un plan définissant un côté intérieur du système orienté vers ledit espace, et un côté extérieur orienté à l'opposé de l'espace, le système comprenant un bâti configuré pour être fixé dans un encadrement de la porte, et un pêne dormant mobile en translation par rapport au bâti entre une position sortie et une position rentrée. Le document GB 191424308 A divulgue un tel système de verrouillage.The present invention relates to a locking system of a door for access to a space, in particular a toilet of a railway vehicle, the closed door extending in a plane defining an inner side of the system facing said space, and a outer side facing away from the space, the system comprising a frame configured to be fixed in a door frame, and a dead bolt movable in translation relative to the frame between an extended position and a retracted position. The document GB 191424308 A discloses such a locking system.

On connaît des systèmes de verrouillage permettant d'ouvrir et de fermer la porte depuis l'intérieur ou l'extérieur des toilettes en actionnant des organes d'ouverture, tels que des poignées ou béquilles, de verrouiller la porte depuis l'intérieur en actionnant un bouton de verrouillage, et de condamner manuellement la porte en actionnant une serrure extérieure, par exemple à clé de Berne. Les clés de Berne sont des clés standard dans le domaine ferroviaire, qui ont été définies par la Convention de Berne en 1886.Locking systems are known for opening and closing the door from inside or outside the toilet by actuating opening members, such as handles or crutches, to lock the door from the inside by actuating a lock button, and to manually condemn the door by operating an external lock, for example with a key from Berne. The keys to Bern are standard keys in the railway field, which were defined by the Berne Convention in 1886.

Il est également connu d'afficher, notamment à l'extérieur, si la porte a été verrouillée par un utilisateur.It is also known to display, especially on the outside, if the door has been locked by a user.

En outre, il est connu d'ajouter, à la demande du client du domaine ferroviaire, des éléments aux systèmes de verrouillage. Ceci entraîne parfois une modification en profondeur du design du système de verrouillage, voire un nouveau design. Il en résulte un coût de revient plus élevé du système de verrouillage dès que celui-ci s'éloigne d'un design « de base ».In addition, it is known to add, at the request of the railway customer, elements to locking systems. This sometimes leads to a profound change in the design of the locking system, or even a new design. This results in a higher cost of the locking system as it moves away from a "basic" design.

Un but de l'invention est donc de fournir un système de verrouillage du type décrit ci-dessus, et d'un coût réduit, même en cas de présence d'éléments supplémentaires demandés par un client.
À cet effet, l'invention a pour objet un système de verrouillage d'une porte d'accès à un espace, notamment des toilettes d'un véhicule ferroviaire, la porte fermée s'étendant dans un plan définissant un côté intérieur du système orienté vers ledit espace, et un côté extérieur orienté à l'opposé de l'espace, le système comprenant :

Le fonctionnement du système 1 va maintenant être décrit.The operation of the system 1 will now be described.

Lorsque l'espace 7 est libre d'utilisation par un utilisateur (non représenté), la porte 5 est non verrouillée. Le bouton de verrouillage 14 est alors, dans l'exemple représenté, dans une position verticale se déduisant de celle représentée sur la figure 2 par une rotation d'un quart de tour vers le haut autour de l'axe D. La plaque de verrouillage intérieure 12 et la plaque de verrouillage extérieure 16 sont alors dans leurs positions ouvertes. Le pêne dormant 18 est dans sa position rentrée, qui se déduit de celle représentée sur les figures par une translation du pêne dormant vers l'intérieur du bâti 10. Le premier signe S1 et le troisième signe S3 sont alignés respectivement avec la lunette intérieure 38 et la lunette extérieure 36.When the space 7 is free for use by a user (not shown), the door 5 is unlocked. The locking button 14 is then, in the example shown, in a vertical position deduced from that shown on the figure 2 by rotating a quarter turn upwards around the D-axis. The locking plate inner 12 and the outer locking plate 16 are then in their open positions. The deadbolt 18 is in its retracted position, which is deduced from that shown in the figures by a translation of the deadbolt towards the interior of the frame 10. The first sign S1 and the third sign S3 are respectively aligned with the inner bezel 38 and the outer bezel 36.

La plaque de condamnation manuelle extérieure 22 est dans sa position neutre, dans laquelle la première fenêtre F1 est alignée avec la lunette extérieure 36. De même, la plaque de condamnation automatique extérieure 28 est dans sa position neutre dans laquelle la troisième fenêtre F3 est alignée avec la lunette extérieure 36. Ainsi, le troisième signe S3 représentatif de l'état « libre » de la porte 5 est visible depuis le côté extérieur B à travers la première fenêtre F1, la troisième fenêtre F3 et la lunette extérieure 36.The outer manual locking plate 22 is in its neutral position, in which the first window F1 is aligned with the outer bezel 36. Similarly, the outer automatic locking plate 28 is in its neutral position in which the third window F3 is aligned. with the outer bezel 36. Thus, the third sign S3 representative of the "free" state of the door 5 is visible from the outer side B through the first window F1, the third window F3 and the outer bezel 36.

De même, la plaque de condamnation manuelle intérieure 26 est dans sa position neutre, de sorte que la deuxième fenêtre F2 est alignée avec la lunette intérieure 38. La plaque de condamnation automatique extérieure 32 est également dans sa position neutre, de sorte que la quatrième fenêtre F4 est alignée avec la lunette intérieure 38. Ainsi, le premier signe S1 également représentatif de l'état « libre » de la porte 5 est visible depuis le côté intérieur à travers la deuxième fenêtre F2, la quatrième fenêtre F4 et la lunette intérieure 38.Similarly, the inner manual locking plate 26 is in its neutral position, so that the second window F2 is aligned with the inner bezel 38. The outer automatic locking plate 32 is also in its neutral position, so that the fourth window F4 is aligned with the inner bezel 38. Thus, the first sign S1 also representative of the "free" state of the door 5 is visible from the inside through the second window F2, the fourth window F4 and the inner bezel 38.

L'utilisateur peut alors ouvrir la porte 5 et pénétrer dans l'espace 7. L'utilisateur referme la porte 5 et la verrouille à l'aide du bouton de verrouillage 14 en le plaçant dans la position représentée sur la figure 2. Ce déplacement du bouton de verrouillage 14 entraîne le bloc formé par la plaque de verrouillage intérieure 12 et la plaque de verrouillage extérieure 16 en rotation autour de l'axe D vers les positions fermées respectives de ces plaques. Par l'intermédiaire du système de liaison 20, ceci actionne le pêne dormant 18 de sa position rentrée vers sa position sortie, et verrouille la porte 5.The user can then open the door 5 and enter the space 7. The user closes the door 5 and locks it with the locking button 14 by placing it in the position shown on the drawing. figure 2 . This movement of the locking button 14 causes the block formed by the inner locking plate 12 and the outer locking plate 16 to rotate about the axis D to the respective closed positions of these plates. Through the connecting system 20, this actuates the deadbolt 18 from its retracted position to its extended position, and locks the door 5.

Le deuxième signe S2 et le quatrième signe S4 sont alors alignés respectivement avec la lunette intérieure 38 et la lunette extérieure 36 et sont visibles respectivement depuis le côté intérieur A et le côté extérieur B.The second sign S2 and the fourth sign S4 are then aligned respectively with the inner bezel 38 and the outer bezel 36 and are respectively visible from the inner side A and the outer side B.

Pour sortir, l'utilisateur déverrouille la porte 5 en actionnant le bouton de verrouillage 14 pour remettre la plaque de verrouillage intérieure 12 et la plaque de verrouillage extérieure 16 dans leurs positions ouvertes. Ceci remet le pêne dormant 18 dans sa position rentrée et la porte 5 peut être ouverte.To exit, the user unlocks the door 5 by actuating the lock button 14 to return the inner locking plate 12 and the outer locking plate 16 to their open positions. This returns the deadbolt 18 to its retracted position and the door 5 can be opened.

Pour mettre l'espace 7 dans l'état « hors service manuel», un opérateur (non représenté), appartenant à priori au personnel de bord du véhicule ferroviaire, agit sur la serrure 24 en utilisant une clé (non représentée). L'action sur la serrure 24 déplace la plaque de condamnation manuelle extérieure 22 de sa position neutre vers sa position fermée (représentée sur la figure 3). La première fenêtre F1 et la deuxième fenêtre F2 ne sont alors plus alignées avec la lunette extérieure 36 et la lunette intérieure 38. Le cinquième signe S5 et le sixième signe S6 sont en revanche alignés avec les lunettes. Le cinquième signe S5 est visible par la lunette extérieure 36 et le sixième signe S6 est visible par la lunette intérieure 38.To put the space 7 in the state "out of manual service", an operator (not shown), belonging in principle to the on-board staff of the railway vehicle, acts on the lock 24 using a key (not shown). The action on the lock 24 moves the outer manual locking plate 22 from its neutral position to its closed position (shown in FIG. figure 3 ). The first window F1 and the second window F2 are then no longer aligned with the outer bezel 36 and the inner bezel 38. The fifth sign S5 and the sixth sign S6, however, are aligned with the glasses. The fifth sign S5 is visible by the outer bezel 36 and the sixth sign S6 is visible by the inner bezel 38.

La plaque de condamnation manuelle extérieure 22 entraîne la plaque de condamnation manuelle intérieure 26 en rotation autour de l'axe D. De même, la plaque de condamnation manuelle extérieure 22 entraîne, grâce à la butée 42 (figure 4), la plaque de verrouillage extérieure 16 et la plaque de verrouillage intérieure 12 en rotation autour de l'axe D pour les amener dans leurs positions fermées respectives. Ceci, par l'intermédiaire du système de liaison 20, déplace le pêne dormant 18 à nouveau vers sa position sortie, ce qui verrouille la porte 5.The outer manual locking plate 22 drives the inner manual locking plate 26 in rotation about the axis D. Similarly, the outer manual locking plate 22 drives, thanks to the stop 42 (FIG. figure 4 ), the outer locking plate 16 and the inner locking plate 12 rotated about the axis D to bring them into their respective closed positions. This, through the connecting system 20, moves the deadbolt 18 back to its extended position, which locks the door 5.

Indépendamment de l'état « libre » ou « occupé », « condamné manuellement » ou non de la porte 5, cette dernière peut être condamnée automatiquement grâce à la gâche électrique 34. Pour ce faire, la gâche électrique 34 passe de sa configuration amovible à sa configuration bloquée.Regardless of the "free" or "busy" state, "manually condemned" or not of the door 5, the latter can be locked automatically thanks to the electric strike 34. To do this, the electric strike 34 passes from its detachable configuration. to its locked configuration.

Pour afficher l'état « hors service automatique » de l'espace 7, le système d'actionnement 30 actionne la plaque de condamnation automatique extérieure 28 en rotation autour de l'axe D, depuis sa position neutre vers sa position hors service automatique. La troisième fenêtre F3 n'est alors plus alignée avec la lunette extérieure 36. En revanche, le septième signe S7 est aligné avec la lunette extérieure 36 et visible à travers cette dernière.In order to display the "automatic off" state of the space 7, the actuating system 30 actuates the outer automatic locking plate 28 in rotation about the axis D, from its neutral position to its automatic off position. The third window F3 is then no longer aligned with the outer bezel 36. In contrast, the seventh sign S7 is aligned with the outer bezel 36 and visible through it.

La plaque de condamnation automatique intérieure 32, étant solidaire mécaniquement de la plaque de condamnation automatique extérieure 28, passe également de sa position neutre à sa position hors service automatique. La quatrième fenêtre F4 n'est plus alignée avec la lunette intérieure 38, mais le huitième signe S8 l'est. Ainsi, depuis le côté intérieur A, c'est le huitième signe S8 qui est visible à travers la lunette intérieure 38.The inner automatic locking plate 32, being mechanically secured to the outer automatic locking plate 28, also moves from its neutral position to its automatic off position. The fourth window F4 is no longer aligned with the inner bezel 38, but the eighth sign S8 is. Thus, from the inner side A, it is the eighth sign S8 which is visible through the inner bezel 38.

Grâce aux éléments décrits ci-dessus, le système 1 est d'un coût réduit, même en présence des éléments optionnels que sont la plaque de condamnation manuelle intérieure 26, la plaque de condamnation automatique extérieure 28 et la plaque de condamnation automatique intérieure 32.Thanks to the elements described above, the system 1 is of a reduced cost, even in the presence of the optional elements which are the inner manual locking plate 26, the outer automatic locking plate 28 and the inner automatic locking plate 32.

De plus, grâce aux éléments optionnels, le système 1 possède un caractère modulaire. Plus précisément, la présence optionnelle de la plaque de condamnation manuelle intérieure 26 permet de créer un module indicateur visuel et tactile « hors service » à l'intérieur des toilettes lorsque la porte 5 est à l'état « hors service manuel ».In addition, thanks to the optional elements, the system 1 has a modular character. More specifically, the optional presence of the locking plate Inner manual 26 makes it possible to create a visual and tactile indicator module "out of service" inside the toilet when the door 5 is in the "out of manual" state.

La présence optionnelle de la plaque de condamnation automatique extérieure 28 permet de créer un module indicateur visuel et tactile « hors service automatique » à l'extérieur de l'espace 7 lorsque la porte 5 est à l'état « hors service automatique ».The optional presence of the external automatic locking plate 28 makes it possible to create a visual and tactile indicator module "out of automatic service" outside the space 7 when the door 5 is in the "off automatic" state.

La présence optionnelle de la plaque de condamnation automatique intérieure 32 permet de créer un module indicateur visuel et tactile « hors service automatique » du côté intérieur A lorsque la porte 5 est à l'état « hors service automatique ».The optional presence of the inner automatic locking plate 32 makes it possible to create an "automatic off" visual and tactile indicator module on the inner side A when the door 5 is in the "off automatic" state.
