Description

La présente invention concerne un dispositif de commande de secours de porte d'autobus pouvant être utilisé,en cas de pression d'air suffisante,comme commande de fermeture pneumatique de la porte.The present invention relates to a bus door emergency control device which can be used, in the event of sufficient air pressure, as a pneumatic door closing control.

Les autocars et autobus munis de porte à commande par vérin pneumatique, ou toute autre source d'énergie, doivent selon la réglementation être munis extérieurement et intérieurement, à proximité de la porte, de boutons ou leviers de commande permettant, en l'absence ou en présence du fluide d'assistance, de déverrouiller celle-ci, l'ouverture étant à effectuer manuellement dans cet usage. Il est par ailleurs souhaité par les utilisateurs d'autobus et d'autocars que ces commandes de secours réglementaires permettent aussi le déplacement assisté de la porte lorsque le fluide d'assistance est présent.Coaches and buses fitted with pneumatic actuator doors, or any other source of energy, must, according to the regulations, be fitted externally and internally, near the door, with buttons or control levers allowing, in the absence or in the presence of the assistance fluid, to unlock the latter, the opening being to be carried out manually in this use. It is moreover desired by the users of buses and coaches that these regulatory emergency commands also allow assisted movement of the door when the assistance fluid is present.

Il existe divers procédés permettant de remplir ces fonctions.There are various methods for performing these functions.

Dans l'un d'entre eux, la porte est déplacée par un vérin pneumatique, lui-même alimenté par une électrovalve.In one of them, the door is moved by a pneumatic cylinder, itself powered by a solenoid valve.

Le dispositif comprend une valve à commande extérieure et intérieure, ou deux valves, une à commande intérieure, l'autre à commande extérieure, qui permettent dans une position l'alimentation de l'électrovalve par le réservoir de servitude du véhicule et dans l'autre position la coupure de cette alimentation et la vidange du circuit aval constitué par l'électrovanne et le vérin de porte. Le vérin n'étant plus soumis à la pression, le vantail de porte se trouve libre, si la valve revient en position normale le circuit se trouve ainsi rétabli.The device comprises a valve with external and internal control, or two valves, one with internal control, the other with external control, which allow in one position the supply of the solenoid valve by the vehicle service tank and in the another position cutting off this supply and emptying the downstream circuit constituted by the solenoid valve and the door actuator. The cylinder is no longer subjected to pressure, the door leaf is free, if the valve returns to normal position the circuit is thus restored.

D'autres systèmes existent ayant pour effet d'alimenter en secours, porte fermée, la deuxième chambre du vérin de porte par la pression du réservoir, ce qui a pour effet d'annuler toute poussée du vérin sur le vantail.Other systems exist which have the effect of supplying the second chamber of the door actuator with the door closed, by the pressure of the reservoir, which has the effect of canceling any thrust of the actuator on the leaf.

Si ces dispositifs assurent correctement la fonction de déverrouillage réglementaire, ce n'est qu'imparfaitement le cas pour la fonction ouverture et fermeture de la porte en usage normal.If these devices correctly perform the regulatory unlocking function, this is only imperfectly the case for the door opening and closing function in normal use.

Dans les deux systèmes décrits, du fait de certaines contraintes de construction, il est souvent nécessaire de recourir à deux valves, l'une accessible de l'extérieur, l'autre de l'intérieur. L'utilisation d'une valve accessible à la fois intérieurement et extérieurement n'est pas réalisable.In the two systems described, due to certain construction constraints, it is often necessary to use two valves, one accessible from the outside, the other from the inside. The use of a valve accessible both internally and externally is not feasible.

Dans les deux cas, la commande manuelle de la porte pour accéder ou quitter le véhicule se décompose en quatre temps.In both cases, the manual control of the door to access or leave the vehicle is broken down into four stages.

Pour accéder au véhicule, par exemple, il faut réaliser les opérations suivantes :

  • a) Actionnement de la valve extérieure, ce qui libère le vantail de porte de tout effort de fermeture.
  • b) Ouverture du vantail de porte manuellement, ce qui permet de monter dans le véhicule.
  • c) Actionnement de la valve intérieure, ce qui va neutraliser le déplacement de la valve extérieure.
  • d) Descente du véhicule et remise à l'état de repos de la valve extérieure, le vantail restant toujours libre.
  • e) Montée dans le véhicule et remise à l'état repos de la valve intérieure, ce qui a pour effet de ramener pneumatiquement le vantail de porte en position fermée.
To access the vehicle, for example, the following operations must be carried out:
  • a) Actuation of the external valve, which frees the door leaf from any closing force.
  • b) Opening the door leaf manually, which allows you to get into the vehicle.
  • c) Activation of the inner valve, which will neutralize the movement of the outer valve.
  • d) Lowering the vehicle and returning to the resting state of the external valve, the leaf remaining always free.
  • e) Mounted in the vehicle and returned to the valve rest state interior, which has the effect of pneumatically returning the door leaf to the closed position.

A la descente, les mêmes opérations dans l'ordre inverse sont nécessaires.On the descent, the same operations in reverse order are necessary.

En réalité, cette manoeuvre trop lourde pour un usage journalier est simplifiée par les utilisateurs.In reality, this maneuver too heavy for everyday use is simplified by users.

Les étapes a) et b) sont toujours respectées mais, au lieu de terminer le processus, l'utilisateur dans le véhicule se penche par l'ouverture et ramène la valve extérieure en position normale, ce qui a pour effet de refermer pneumatiquement la porte, l'usager devant alors par un mouvement rapide éviter le choc du vantail, ce qui n'est pas sans poser des problèmes de sécurité.Steps a) and b) are always followed, but instead of completing the process, the user in the vehicle leans through the opening and returns the external valve to the normal position, which has the effect of closing the door pneumatically. , the user must then by a rapid movement avoid the impact of the leaf, which is not without posing safety problems.

Afin de remédier aux inconvénients des systèmes connus, la présente invention propose un dispositif de commande de secours de l'ouverture d'une porte, notamment de véhicule de transport en commun dont la fermeture est assurée par un vérin à deux chambres dont l'entrée de la chambre de fermeture est, en position fermée, reliée à une source de pression et dont la chambre d'ouverture est, en position fermée, mise à l'échappement, caractérisé en ce qu'il est constitué de deux valves de distribution à tiroir et à commande manuelle montées en série et disposées l'une à l'intérieur et l'autre à l'extérieur du véhicule et un sélecteur de circuit dont une entrée est normalement mise à l'échappement et dont la sortie est reliée à l'entrée de la chambre d'ouverture du vérin lorsque les deux valves sont dans leur position de repos, la première entrée de la première valve est reliée à la source de pression, la première sortie correspondante étant reliée à la première entrée de la seconde valve dont la première sortie est bouchée, et la seconde entrée de la première valve est mise à l'échappement, la seconde sortie correspondante étant reliée à la seconde entrée de la seconde valve dont la seconde sortie est reliée à la seconde entrée du sélecteur de circuit.In order to overcome the drawbacks of known systems, the present invention provides a device for emergency control of the opening of a door, in particular of a public transport vehicle, the closure of which is ensured by a two-chamber cylinder, the inlet of which of the closing chamber is, in the closed position, connected to a pressure source and whose opening chamber is, in the closed position, exhausted, characterized in that it consists of two distribution valves to drawer and manual control mounted in series and arranged one inside and the other outside the vehicle and a circuit selector whose input is normally exhausted and whose output is connected to the entry of the cylinder opening chamber when the two valves are in their rest position, the first inlet of the first valve is connected to the pressure source, the corresponding first outlet being connected to the first inlet of the second valve whose the first outlet is blocked, and the second inlet of the first valve is turned on the exhaust, the corresponding second outlet being connected to the second inlet of the second valve, the second outlet of which is connected to the second inlet of the circuit selector.

On décrira maintenant l'invention en se référant au dessin annexé dont la figure unique est un schéma de représentation du dispositif de commande de secours de la présente invention.The invention will now be described with reference to the accompanying drawing, the single figure of which is a diagram showing the emergency control device of the present invention.

Le dispositif de commande normal de l'ouverture et de la fermeture de la porte est constitué par un vérin généralement pneumatique à double effet V et par une électrovalve de commande C. Le vérin V comprend une chambre de fermeture CF et une chambre d'ouverture C0.The normal device for controlling the opening and closing of the door is constituted by a generally pneumatic double-acting cylinder V and by a control solenoid valve C. The cylinder V comprises a closing chamber CF and an opening chamber C0.

L'électrovalve C représentée ici dans sa position de commande de la fermeture de la porte comprend une première entrée E1C reliée à la source de pression S et une seconde entrée E2C mise à l'échappement. La première sortie SIC de l'électrovalve C est reliée à l'entrée EFV de la chambre de fermeture CF du vérin V tandis que la seconde sortie S2C est reliée à la première entrée E1S d'un sélecteur de circuit S dont la sortie SS est reliée à l'entrée EOV de la chambre d'ouverture du vérin V.The solenoid valve C shown here in its position for controlling the closing of the door comprises a first input E1C connected to the pressure source S and a second input E2C exhausted. The first output SIC of the solenoid valve C is connected to the input EFV of the closing chamber CF of the jack V while the second output S2C is connected to the first input E1S of a circuit selector S whose output SS is connected to the EOV input of the opening chamber of the jack V.

Dans la position de fermeture représentée, la chambre de fermeture CF du vérin V est sous pression tandis que la chambre d'ouverture CO est mise à l'échappement en E2C au travers du sélecteur S dont la seconde entrée E2S est également à l'échappement comme cela sera explicité plus loin.In the closed position shown, the closing chamber CF of the jack V is under pressure while the opening chamber CO is exhausted at E2C through the selector S, the second inlet E2S of which is also at the exhaust as will be explained later.

Conformément à l'invention, la commande de secours de l'ouverture de la porte s'effectue par mise sous pression de la chambre d'ouverture CO du vérin V au travers du sélecteur de circuit S sur la seconde entrée E2S duquel on agit au moyen de deux valves de distribution à tiroir et à commande manuelle A et B.In accordance with the invention, the emergency control of the opening of the door is carried out by pressurizing the opening chamber CO of the jack V through the circuit selector S on the second input E2S from which one acts at by means of two manually operated spool valves A and B.

Les deux valves A et B sont identiques et du type dit "4-2", c'est-à-dire à 2 entrées + 2 sorties et 2 positions. Les appellations "entrée" et "sortie" sont ici employées à titre de commodité uniquement, les sens d'écoulement pouvant être inversés comme on le verra plus loin.The two valves A and B are identical and of the so-called "4-2" type, that is to say with 2 inputs + 2 outputs and 2 positions. The names "inlet" and "outlet" are used here for convenience only, the directions of flow can be reversed as will be seen below.

Lorsque les deux valves A et B sont, comme c'est le cas sur le schéma, dans leur position de repos, les connexions sont les suivantes :

  • - la première entrée ElA de la première valve A est reliée à la source de pression, la première sortie correspondante SIA étant reliée à la première entrée EIB de la seconde valve B dont la première sortie correspondante SIB est bouchée,
  • - la seconde entrée E2A de la première valve A étant mise à l'échappement, la seconde sortie S2A étant reliée à la seconde entrée E2B de la seconde valve B dont la seconde entrée correspondante est reliée à la seconde entrée E2S du sélecteur de circuit S.
When the two valves A and B are, as in the diagram, in their rest position, the connections are as follows:
  • the first inlet ElA of the first valve A is connected to the pressure source, the first corresponding outlet SIA being connected to the first inlet EIB of the second valve B whose first corresponding outlet SIB is blocked,
  • - the second input E2A of the first valve A being exhausted, the second output S2A being connected to the second input E2B of the second valve B whose second corresponding input is connected to the second input E2S of the circuit selector S .

L'une des valves A est montée à l'extérieur du véhicule tandis que l'autre valve B est montée à l'intérieur.One of the valves A is mounted outside the vehicle while the other valve B is mounted inside.

Le fonctionnement de la commande de secours de l'ouverture de la porte est le suivant :

  • - Si l'utilisateur actionne l'une des deux valves, par exemple la valve A, la pression d'alimentation présente à l'entrée ElA est transmise à la sortie S2A puis, au travers de la seconde valve B qui n'a pas bougé, à la seconde entrée E2S du sélecteur de circuit S. La mise sous pression de l'entrée E2S a pour effet de piloter le sélecteur et de provoquer l'alimentation de l'entrée EOV de la chambre d'ouverture CO du vérin V. Dans cette position, les deux chambres CF et CO du vérin sont sous pression et les efforts appliqués sur chaque face du vérin s'équilibrent permettant ainsi une ouverture manuelle de la porte, l'utilisateur pouvant alors pénétrer dans le véhicule.
  • - L'utilisateur peut à nouveau provoquer la fermeture de la porte depuis l'extérieur en ramenant la valve A dans sa position de repos initiale.
  • - L'utilisateur peut également provoquer la fermeture de la porte en agissant depuis l'intérieur sur la valve B. Par cette manoeuvre, la sortie S2B est mise en communication avec l'entrée EIB puis au travers de la valve A avec l'entrée E2A qui est une mis à l'échappement. La seconde entrée E2S se trouve ainsi à nouveau mise à l'échappement, ce qui a pour effet de provoquer la dépressurisation de la chambre d'ouverture CO du vérin V et donc la fermeture de la porte. Lors de la même manoeuvre, la sortie bouchée S1B est mise en communication avec l'entrée E2B qui est elle-même reliée au travers de la valve A avec la source de pression S.
The operation of the emergency door opening control is as follows:
  • - If the user actuates one of the two valves, for example valve A, the supply pressure present at the inlet ElA is transmitted to the outlet S2A then, through the second valve B which has not moved, at the second input E2S of the circuit selector S. Pressurizing the input E2S has the effect of controlling the selector and causing the supply of the input EOV of the opening chamber CO of the jack V In this position, the two chambers CF and CO of the jack are under pressure and forces applied to each side of the cylinder are balanced, allowing manual opening of the door, the user being able to enter the vehicle.
  • - The user can again cause the door to close from the outside by returning valve A to its initial rest position.
  • - The user can also cause the door to close by acting from the inside on valve B. By this operation, the S2B output is put in communication with the EIB input and then through valve A with the input. E2A which is an exhaust. The second input E2S is thus again exhausted, which has the effect of causing the depressurization of the opening chamber CO of the jack V and therefore the closing of the door. During the same operation, the blocked outlet S1B is put in communication with the inlet E2B which is itself connected through the valve A with the pressure source S.

On comprendra aisément qu'une opération de commande d'ouverture de secours qui débuterait par l'actionnement de la valve B se réaliserait de façon identique compte tenu de la parfaite symétrie du dispositif.It will easily be understood that an emergency opening control operation which would start with the actuation of the valve B would be carried out in an identical manner taking into account the perfect symmetry of the device.

Le passage de la position normale à la position de secours, et inversement, peut être obtenu après une seule manoeuvre de l'une des valves A ou B et ceci quelle que soit la position antérieure des valves. L'accès ou l'abandon d'urgence du véhicule peut ainsi se réaliser avec deux actionnements consécutifs effectués chacun d'un côté de la porte contrairement aux dispositifs de l'art antérieur mentionné plus haut.The transition from the normal position to the emergency position, and vice versa, can be obtained after a single operation of one of the valves A or B and this regardless of the anterior position of the valves. The emergency access or abandonment of the vehicle can thus be achieved with two consecutive actuations each carried out on one side of the door unlike the devices of the prior art mentioned above.
