Description

Stand der TechnikState of the art

Die Erfindung geht aus von einer Türbetätigungseinrichtung nach der Gattung des Hauptanspruchs. Eine derartige Türbetätigungseinrichtung ist bekannt (DE-OS 28 07 050).The invention relates to a door operating device according to the preamble of the main claim. Such a door operating device is known (DE-OS 28 07 050).

Diese bekannte Einrichtung behandelt am Ende der Beschreibung und im offengelegten Anspruch 8 eine Notsteuerung, die auf elektrischem oder mechanischem Weg ein Lösen der Verriegelung ermöglicht. Auf diese Weise wird die eventuelle zufällig unter Druck stehende Schließseite des Zweikammer-Arbeitszylinders entlüftet, um ein leichtes Öffnen der Tür von Hand zu ermöglichen. Dabei kann es aber geschehen, daß die Schließseite über die Notsteuerung Druck erhält, ohne daß auf der Gegenseite ein solcher vorhanden ist. Dann ist dort die Endlagendämpfung ausgeschaltet, und die Tür kann durch Druckanstieg auf der Schließseite schlagartig geschlossen werden. Dadurch sind aber schon schwere Unfälle enstanden.This known device deals at the end of the description and in the disclosed claim 8, an emergency control that enables a release of the lock by electrical or mechanical means. In this way, the possibly accidentally pressurized closing side of the two-chamber working cylinder is vented to enable easy opening of the door by hand. However, it can happen that the closing side receives pressure via the emergency control, without such being present on the opposite side. The end position damping is then switched off there and the door can be closed suddenly due to an increase in pressure on the closing side. This has already resulted in serious accidents.

Vorteile der ErfindungAdvantages of the invention

Die erfindungsgemäße Türbetätigungseinrichtung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß ein die Notsteuerung bewirkendes Mehrwegeventil selbst die Verriegelung übernehmen kann und daß diese Verriegelung abhängig von dem vom Türventil eingesteuerten Druck automatisch lösbar ist. Und zwar wird die Verriegelung gelöst, wenn das Türventil seine Öffnungsstellung eingenommen hat. Damit ist erreicht, daß ausgehend von jeder Stellung des Arbeitszylinders und in jeder Richtung die Endlagendämpfung des Arbeitszylinders wirksam ist. Dadurch ist gewährleistet, daß ein schlagartiges Bewegen der Tür vermieden ist, wenn die Notsteuerung von Hand betätigt wird. Schwere Unfälle sind damit vermieden. Außerdem kann in dieser Offenstellung eine Betätigung der Notsteuerung kein Schließen der Tür und keine Verriegelung des Mehrwegeventils bewirken. Desweiteren ist auch eine Notbetätigung möglich, wenn die Elektrik, d.h. der Magnet des Türventils ausgefallen ist. Die besondere Verriegelung erleichtert schließlich auch die Inspektion. Weitere vorteilhafte Merkmale der Erfindung ergeben sich aus den Unteransprüchen.The door actuation device according to the invention with the characterizing features of the main claim has the advantage that a multi-way valve causing the emergency control itself can take over the locking and that this locking can be released automatically depending on the pressure applied by the door valve. The lock is released when the door valve has reached its open position. This ensures that the end position damping of the working cylinder is effective starting from every position of the working cylinder and in every direction. This ensures that a sudden movement of the door is avoided when the emergency control is operated by hand. This prevents serious accidents. In addition, in this open position, actuation of the emergency control cannot cause the door to close and the multi-way valve not to be locked. Furthermore, emergency operation is also possible if the electrical system, i.e. the solenoid of the door valve has failed. The special locking also makes inspection easier. Further advantageous features of the invention emerge from the subclaims.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Eine Tür 1 ist über eine Kolbenstange 2 mit einem doppelwirkenden Kolben 3 eines Zweikammer-Arbeitszylinders 4 verbunden. Die zwei Kammern 5 und 6 des Arbeitszylinders 4 sind über Anschlüsse an je eine Luftleitung 7 bzw. 8 angeschlossen, von denen die von der Öffnungsseite x des Arbeitszylinders 4 ausgehende Leitung 7 unmittelbar zu einem Türventil 9 führt, das als 3/2-Wege-Magnetventil ausgebildet ist und an das ein Vorratsbehälter 20 als Druckquelle angeschlossen ist.A door 1 is connected via a piston rod 2 to a double-acting piston 3 of a two-chamber working cylinder 4. The two chambers 5 and 6 of the working cylinder 4 are connected via connections to an air line 7 or 8, of which the line 7 starting from the opening side x of the working cylinder 4 leads directly to a door valve 9, which as a 3/2-way Solenoid valve is formed and to which a reservoir 20 is connected as a pressure source.

Die andere, von der Schließseite y des Arbeitszylinders 4 ausgehende Leitung 8 führt zu einer Notsteuerung 10 und dort zu einem als 3/2-Wege-Ventil 11 ausgebildeten Mehrwegeventil, das von Hand betätigbar ist. Die Betätigung _des Ventils 11 kann entweder durch einen Knebel oder einen Drehknopf erfolgen, wobei die Betätigung vorzugsweise so arbeiten soll, daß sie nur in einer Richtung Kraft übertragen kann.The other line 8 starting from the closing side y of the working cylinder 4 leads to an emergency control 10 and there to a multi-way valve designed as a 3/2-way valve 11 which can be operated by hand. The actuation of the valve 11 can take place either by means of a toggle or a rotary knob, the actuation preferably working in such a way that it can transmit force only in one direction.

Als 3/2-Wege-Ventil 11 hat sich ein Drehschieberventil bewährt, das mit einer Drehfeder versehen ist. Beim Betätigen wird die Drehfeder gespannt, und am Ende der Verdrehung wird eine Radial-Verriegelung 12 (Figuren 2 und 3) erreicht, und diese Verriegelung ist über ein Arbeitsglied 13 pneumatisch lösbar, wonach der pneumatische Druck auch die Rückführung des 3/2-Wege-Ventils 11 in seine Ausgangsstellung unterstützt. Ein solches 3/2-Wege-Ventil ist in der DE-OS 24 39 589 beschrieben.A rotary slide valve, which is provided with a torsion spring, has proven itself as a 3/2-way valve 11. When actuated, the torsion spring is tensioned, and at the end of the rotation, a radial lock 12 (Figures 2 and 3) is reached, and this lock can be released pneumatically via a working member 13, after which the pneumatic pressure also returns the 3/2 way -Valve 11 supported in its starting position. Such a 3/2-way valve is described in DE-OS 24 39 589.

Dem Arbeitsglied 13 ist eine Drossel 14 vorgeschaltet. Die Drossel 14 kann auch durch eine Feder 14' am Arbeitsglied 13 ersetzt sein. Drossel 14 oder Feder 14' bilden eine druck- oder zeitabhängige Verzögerungseinrichtung. Arbeitsglied 13 und Drossel 14 liegen in einer Zweigleitung 15, die Verbindung mit der Luftleitung 7 hat, die einerseits mit der Öffnungsseite x des Arbeitszylinders 4 und mit dem Türventil 9 verbunden ist und die andererseits über eine Leitung 16 an einen dritten Anschluß des Ventils 11 angeschlossen ist.A throttle 14 is connected upstream of the working member 13. The throttle 14 can also be replaced by a spring 14 'on the working member 13. Throttle 14 or spring 14 'form a pressure or time-dependent delay device. Working member 13 and throttle 14 are in a branch line 15, which has connection to the air line 7, which is connected on the one hand to the opening side x of the working cylinder 4 and with the door valve 9 and on the other hand connected via a line 16 to a third connection of the valve 11 is.

WirkungsweiseMode of action

Die Figuren 1 bis 4 zeigen die Türbetätigungseinrichtung in verschiedenen Stellungen. Es sind deshalb für gleiche Teile die gleichen Bezugszahlen verwendet.Figures 1 to 4 show the door operating device in different positions. The same reference numbers are therefore used for the same parts.

In der Figur 1 hat das Türventil 9 eine derartige Stellung, daß die Tür 1 geschlossen ist. Es wird nun angenommen, daß der das Türventil 9 verstellende Magnet keinen Strom erhält, dann kann das Türventil 9 nicht umschalten und die Fahrgäste können nicht aussteigen.In Figure 1, the door valve 9 has such a position that the door 1 is closed. It is now assumed that the solenoid adjusting the door valve 9 receives no power, then the door valve 9 cannot switch over and the passengers cannot get out.

Die Figur 2 zeigt den Zustand der Türbetätigungseinrichtung, wenn von irgend jemand die Notsteuerung 10 betätigt wurde. Das von Hand betätigbare 3/2-Ventil 11 nimmt dann seine andere Stellung ein, in der nun auch die Schließseite y des Arbeitszylinders 4 entlüftet wird, und zwar über das 3/2-Ventil 11, die Leitungen 16 und 7 und das Türventil 9. Dadurch kann die Tür 1 mit dem doppelt wirkenden Kolben 3 in dem Arbeitszylinder 4 ohne Widerstand in Offenstellung verschoben werden. Die Fahrgäste können aussteigen.FIG. 2 shows the state of the door operating device when the emergency control 10 has been operated by someone. The manually operated 3/2 valve 11 then assumes its other position, in which the closing side y of the working cylinder 4 is now also vented, specifically via the 3/2 valve 11, the lines 16 and 7 and the door valve 9 As a result, the door 1 with the double-acting piston 3 in the working cylinder 4 can be moved into the open position without resistance. The passengers can get out.

Die Figur 3 zeigt, daß bei verriegeltem 3/2-Ventil 11 die Tür in jeder Stellung zwischen "zu" und "offen" stehen kann. Das Ventil 11 steht in Kurzschlußstellung. Damit ist die Vorschrift erfüllt, daß eine Betätigung der Notsteuerung keine druckmittelbewirkte Bewegung der Tür nach sich zieht. Die Stromversorgung des Magneten des Tüventils 9 ist wieder intakt; deshalb kann das Türventil 9 in Stellung "öffnen" geschaltet werden. Dadurch werden die beiden Arbeitskammern 5 und 6 des Arbeitszylinders 4 gleichmäßig belüftet. Die Tür 1 bleibt aber stehen wie sie stand.FIG. 3 shows that when the 3/2 valve 11 is locked, the door can be in any position between "closed" and "open". The valve 11 is in the short-circuit position. This fulfills the requirement that actuation of the emergency control does not result in pressure-induced movement of the door. The power supply to the magnet of the valve 9 is intact again; therefore the door valve 9 can be switched to the "open" position. As a result, the two working chambers 5 and 6 of the working cylinder 4 are evenly ventilated. Door 1 remains as it was.

In der Figur 4 ist nun zu sehen, daß sich durch den beispielsweise über die Drossel 14 verzögerten Druckanstieg am Arbeitsglied 13 die Verriegelung gelöst hat und das 3/2-Ventil 11 der Notsteuerung 10 wieder in seine Ausgangsstellung zurückgekehrt ist. Die Schließseite y des Arbeitszylinders 4 wird entlüftet, und die Tür 1 geht in Offenstellung. Es ist also ein wichtiges Merkmal der erfindungsgemäßen Einrichtung, daß die Notsteuerung 10 nur dann in ihre Ausgangsstellung zurückgeht, wenn das Türventil 9 vorher seine Offenstellung eingenommen hatte. Damit ist erreicht, daß ausgehend von jeder Stellung des Arbeitszylinders und in jeder Richtung die Endlagendämpfung im Arbeitszylinder wirksam ist. In der Offenstellung kann eine Betätigung der Notsteuerung kein Schließen der Tür und keine Verriegelung der Notbetätigung bewirken. weil das Arbeitsglied 13 der Verriegelung 12 unter Druck steht (Stellung nach Figur 4).In FIG. 4 it can now be seen that the locking on the working member 13 has been released by the pressure increase delayed, for example, via the throttle 14, and the 3/2 valve 11 of the emergency control 10 has returned to its starting position. The closing Side y of the working cylinder 4 is vented and the door 1 goes into the open position. It is therefore an important feature of the device according to the invention that the emergency control 10 only returns to its starting position if the door valve 9 had previously assumed its open position. This ensures that the end position damping in the working cylinder is effective starting from every position of the working cylinder and in every direction. In the open position, actuation of the emergency control cannot cause the door to close or lock the emergency actuation. because the working member 13 of the lock 12 is under pressure (position according to Figure 4).

Zum Schließen der Tür 1 muß nun erst wieder das Türventil 9 in die Stellung nach Figur 1 gebracht werden.To close the door 1, the door valve 9 must first be brought into the position shown in FIG. 1.
