Abstract
Description
Gegenstand der Erfindung ist eine Einrichtung an einer Aufzugskabine zum temporären Koppeln eines Kabinentürflügels mit einem Schachttürflügel und zum Betätigen einer Kabinentürverriegelung, wie in den Patentansprüchen definiert.The invention relates to a device on an elevator car for temporarily coupling a car door leaf with a shaft door leaf and for actuating a car door lock, as defined in the patent claims.
Die Erfindung betrifft das Problem, die Öffnungsbewegung eines Aufzugs-Kabinentürflügels nur dann zuzulassen, wenn die Aufzugskabine sich auf dem Niveau eines Stockwerks befindet, d. h. wenn die Kabinentüre einer Schachttüre des Aufzugs gegenübersteht.The invention relates to the problem of allowing the opening movement of an elevator car door leaf only when the elevator car is at the level of a floor, i. H. when the car door facing a shaft door of the elevator.
Mit der Patentschrift
Am Ende einer Türflügel-Schliessbewegung werden durch die Schliessbewegung des linear wirkenden Antriebsmittels die Verstellelemente in eine Stellung zurückschwenkt, in der die Mitnehmerkufen von den Kopplungselementen beabstandet sind, so dass die Verriegelung des Schachttürflügels in ihre Verriegelungsstellung zurückkehrt.At the end of a door leaf closing movement, the adjusting elements are pivoted back into a position in which the Mitnehmerkufen are spaced from the coupling elements by the closing movement of the linearly acting drive means, so that the locking of the shaft door panel returns to its locking position.
Zu diesem Zweck weist eine der Mitnehmerkufen im Bereich ihrer aussen liegenden, d. h. der mit dem korrespondierenden Kopplungselement am Schachttürflügel (Kopplungsrolle) zusammenwirkenden, Kufenfläche eine Tastkufe auf. Diese erstreckt sich parallel zur Mitnehmerkufe und ist mittels Lenkerfedem so mit dieser verbunden, dass sie in unbelastetem Zustand einige Millimeter von dieser beabstandet ist. Die bei einem Kopplungsvorgang (Mitnehmerspreizung) durch das Kopplungselement auf die Tastkufe ausgeübte Kontaktkraft bewirkt deren Verschiebung gegen die Federkraft der Lenkerfedem in Richtung der Mitnehmerkufe. Die Tastkufe weist einen Nocken auf, der ihre durch das Kopplungselement bewirkte Verschiebung gegenüber der Mitnehmerkufe und damit dem Kabinentürflügel auf einen an diesem Kabinentürflügel gelagerten Kabinentürriegel überträgt und den Kabinentürflügel entriegelt.For this purpose, one of the Mitnehmerkufen in the region of its outer lying, ie the cooperating with the corresponding coupling element on the landing door wing (coupling roller), skid surface on a Tastkufe. This extends parallel to Mitnehmerkufe and is connected by means Lenkerfedem with this that it is spaced a few millimeters from it in the unloaded state. The force exerted by the coupling element on the Tastkufe in a coupling process (Mitnehmerspreizung) contact force causes their displacement against the spring force of the Lenkerfedem in the direction of Mitnehmerkufe. The Tastkufe has a cam, which caused by the coupling element displacement relative to the Mitnehmerkufe and thus the car door leaf on a mounted on this car door leaf Cabin door latch transfers and unlocks the cabin door wing.
Erfolgt ein Türöffnungsbefehl und eine resultierende Spreizung der Mitnehmerkufen des Kopplungsmechanismus, wenn die Tür der Aufzugskabine nicht einer Schachttüre gegenübersteht, so gelangen die Mitnehmerkufen wie auch die Tastkufe nicht in Kontakt mit einem der Kopplungselemente an den Schachttürflügeln. Die Tastkufe wird daher nicht gegen die Mitnehmerkufe verschoben, und der Kabinentürriegel bleibt in seiner Verriegelungsstellung. Ein die Stellung des Kabinentürriegels überwachender Sensor verhindert zusätzlich das Einschalten des Türantriebsmotors.If a door opening command and a resulting spread of the Mitnehmerkufen the coupling mechanism, when the door of the elevator car does not face a shaft door, the Mitnehmerkufen get as well as the Tastkufe not in contact with one of the coupling elements on the shaft door leaves. The Tastkufe is therefore not moved against the Mitnehmerkufe, and the cab door latch remains in its locked position. A sensor monitoring the position of the car door bolt additionally prevents the door drive motor from being switched on.
Diese Türantriebsvorrichtung weist einige Nachteile auf.This door drive device has some disadvantages.
Der wesentlichste Nachteil besteht darin, dass auf einer Seite des Kopplungsmechanismus zwei Kufen, nämlich eine Mitnehmerkufe und die daran geführte Tastkufe erforderlich sind. Dies hat einerseits einen hohen Material- und Fertigungsaufwand zur Folge. Andererseits resultieren daraus technische Nachteile, wie Präzisionsverluste und grosse zu bewegende Massen.The most significant disadvantage is that on one side of the coupling mechanism two runners, namely a Mitnehmerkufe and guided Tastkufe are required. This has on the one hand a high material and manufacturing costs result. On the other hand, this results in technical disadvantages, such as precision losses and large masses to be moved.
Ein weiterer Nachteil ist die relativ unpräzise Führung der Tastbewegung der Tastkufe durch die Lenkerfedern, was zur Kompensation einen entsprechend grösseren Tastweg erfordert.Another disadvantage is the relatively imprecise guidance of the tactile movement of the Tastkufe by the handlebar springs, which requires a correspondingly larger Tastweg to compensate.
Die beschränkte Stabilität der Tastkufenführung durch Lenkerfedern bei aussermittigem Kraftangriff an der Tastkufe hat zusätzliche Ungenauigkeiten und damit einen grösseren erforderlichen Tastweg zur Folge. Dies ist insbesondere dann der Fall, wenn das Kopplungselement wegen veränderlichem Abstand zwischen Aufzugskabine und Schachttüre nur im seitlichen Randbereich der Tastkufe angreift.The limited stability of the skid guide by handlebar springs in off-center force attack on the Tastkufe has additional inaccuracies and thus a larger required Tastweg result. This is the case, in particular, when the coupling element engages only in the lateral edge region of the sensing skid because of the variable distance between the elevator cage and the shaft door.
Grössere Tastwege erhöhen jedoch die Biegespannungen in den Lenkerfedern und damit das Risiko von Federbrüchen.However, larger tactile paths increase the bending stresses in the handlebar springs and thus the risk of spring breaks.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Einrichtung der vorstehend beschriebenen Art zu schaffen, die die genannten Nachteile nicht aufweist.The present invention has for its object to provide a device of the type described above, which does not have the disadvantages mentioned.
Erfindungsgemäss wird die Aufgabe durch die im Patentanspruch 1 angegebenen Massnahmen gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung gehen aus den abhängigen Ansprüchen 2 bis 9 hervor.According to the invention the object is achieved by the measures specified in claim 1. Advantageous embodiments and further developments of the invention will become apparent from the
Die durch die Erfindung erreichten Vorteile sind im Wesentlichen darin zu sehen, dass eine Kopplungseinrichtung auf der Tastseite eine Mitnehmerkufe aufweist, die die Mitnahme des Kopplungselements bewirkt und gleichzeitig das Vorhandensein eines Kopplungselements erfasst (detektiert) und bei Vorhandensein des Kopplungselements den Kabinentürriegel entriegelt. Die Mitnehmerkufe ist über Gelenkstücke mit zwei Verstell-elementen verbunden, wobei die Gelenkstücke so ausgebildet und angeordnet sind, dass eine von den Kopplungselementen auf die Mitnehmerkufe ausgeübte Kontaktkraft eine sicher und genau geführte Zusatzbewegung der Gelenkstücke und der Mitnehmerkufe bewirkt. Mit dem Ausdruck "sicher und genau geführte Zusatzbewegung" ist einerseits gemeint, dass durch die Gelenkstücke das Risiko eines Lenkerfederbruchs beseitigt ist und andererseits, dass die Gelenkstücke die Zusatzbewegung genauer und stabiler führen, als dies durch die elastischen Lenkerfedem gemäss Stand der Technik möglich ist.The advantages achieved by the invention are essentially to be seen in that a coupling device on the tactile side has a Mitnehmerkufe that causes the entrainment of the coupling element and simultaneously detects the presence of a coupling element (detected) and unlocks the car door latch in the presence of the coupling element. The Mitnehmerkufe is connected via joint pieces with two adjustment elements, wherein the joint pieces are formed and arranged so that a force exerted by the coupling elements on the Mitnehmerkufe contact force causes a safe and accurate guided additional movement of the joint pieces and the Mitnehmerkufe. By the expression "safe and precisely guided additional movement" is meant, on the one hand, that the joint pieces eliminate the risk of a bar spring break and, on the other hand, that the joint pieces guide the additional movement more accurately and stably than is possible by the elastic handlebar springs according to the prior art.
Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung gehen aus den Unteransprüchen hervor.Advantageous embodiments and modifications of the invention will become apparent from the dependent claims.
Gemäss einer bevorzugten Ausführungsform der erfindungsgemässen Einrichtung bewirkt ein die Öffnungs- und Schliessbewegung der Türflügel antreibendes Antriebselement oder ein separater Türkopplungsantrieb die Schwenkbewegung des einen Verstellelements, wobei eine synchrone Schwenkbewegung des anderen Verstellelements durch eine direkt auf korrespondierenden Hebelarmen der beiden Verstellelemente gelagerte Mitnehmerkufe gewährleistet ist. Diese Konstruktion erlaubt eine parallelogrammartige, gelenkige Lagerung der tastenden Mitnehmerkufe auf den beiden anderen korrespondierenden Hebelarmen der Verstellelemente.According to a preferred embodiment of the inventive device causes a the opening and closing movement of the door driving drive element or a separate door coupling drive the pivotal movement of the one adjustment, wherein a synchronous pivotal movement of the other adjustment by a directly on Corresponding lever arms of the two adjusting elements mounted Mitnehmerkufe is guaranteed. This construction allows a parallelogram, articulated mounting of the momentary Mitnehmerkufe on the other two corresponding lever arms of the adjusting elements.
Für den Antrieb von sehr schweren Türflügeln und bei erhöhten Ansprüchen betreffend Geräuscharmut kann es vorteilhaft sein, die Schwenkbewegung der Verstellelemente durch einen separaten Türkopplungsantrieb, z. B. durch einen Spindelhubmotor oder einen Getriebemotor, zu erzeugen.For the drive of very heavy door leaves and increased demands regarding low noise, it may be advantageous to the pivoting movement of the adjusting elements by a separate door coupling drive, for. B. by a Spindelhubmotor or a geared motor to produce.
Zweckmässigerweise sind die die Mitnehmerkufen mit den schwenkbaren Verstellelementen verbindenden Gelenkstücke an den Enden korrespondierender Hebelarme der beiden Verstellelemente gelenkig gelagert und so angeordnet, dass die Schwenkwinkel der zwischen den Verstellelementen und den Gelenkstücken ausführbaren Schwenkbewegungen mechanisch begrenzt sind.Conveniently, the connecting pieces connecting the Mitnehmerkufen with the pivotable adjusting elements at the ends of corresponding lever arms of the two adjusting elements are articulated and arranged so that the pivot angle of executable between the adjusting elements and the joint pieces pivoting movements are mechanically limited.
Vorteilhafte Bedingungen für die Umsetzung der Kontaktkraft zwischen Kopplungselement und erster Mitnehmerkufe in eine Schwenkbewegung ergeben sich, wenn die Schwenkbewegung der Gelenkstücke so begrenzt ist, dass ihre durch die Verbindungslinie zwischen ihren Lagerstellen definierte Gelenkstückachse in einem Winkel von 20° bis 60° zur Längsachse der Mitnehmerkufen ausgerichtet ist, wenn sich die Verstellelemente in Kopplungsstellung befinden und die erste Mitnehmerkufe nicht durch ein Kopplungselement belastet ist.Advantageous conditions for the implementation of the contact force between the coupling element and the first Mitnehmerkufe in a pivoting movement arise when the pivotal movement of the joint pieces is limited so that their defined by the line connecting their bearings hinge piece axis at an angle of 20 ° to 60 ° to the longitudinal axis of the Mitnehmerkufen is aligned when the adjusting elements are in the coupling position and the first Mitnehmerkufe is not burdened by a coupling element.
Vorzugsweise liegen die Schwenkwinkel der zwischen den Verstellelementen und den Gelenkstücken ausführbaren Schwenkbewegungen zwischen 10 und 60 Grad. Je nach Länge der Gelenkstücke ergeben sich in diesem Schwenkwinkelbereich für die Entriegelung des Riegels günstige Mitnehmerbewegungen.Preferably, the pivoting angles of the executable between the adjusting elements and the joint pieces pivoting movements are between 10 and 60 degrees. Depending on the length of the joint pieces result in this swivel angle range for the unlocking of the bar favorable driving movements.
In vorteilhafter Weise erfolgt die mechanische Begrenzung der Schwenkwinkel dadurch, dass mindestens eines der Gelenkstücke je zwei um die sie mit dem jeweiligen Verstellelement verbindende Gelenkachse angeordnete Anschläge aufweist, die in den jeweiligen Begrenzungspositionen auf korrespondierende Anschläge am Verstellelement auftreffen.Advantageously, the mechanical limitation of the Pivoting angle characterized in that at least one of the joint pieces each has two arranged around the hinge axis connecting them to the respective adjusting element stops, which impinge in the respective limiting positions on corresponding stops on the adjusting element.
Bei der bevorzugten Ausführungsform der Erfindung nehmen bei vorhandener Kopplungsstellung der Verstellelemente und fehlender Einwirkung einer Kontaktkraft vom Kopplungselement auf die an den Gelenkstücken gelagerte Mitnehmerkufe die Gelenkstücke und die mit ihnen verbundene Mitnehmerkufe infolge ihres Gewichts oder einer Federkraft eine durch einen der Anschläge definierte gewichts- oder federzentrierte Stellung ein, in der keine der Komponenten der Einrichtung auf die Kabinentürverriegelung einwirkt. Damit wird erreicht, dass keine Entriegelung der Kabinentüre erfolgt, wenn die Mitnehmerkufen beim Kopplungsvorgang (Mitnehmerspreizung) nicht mit einem Kopplungselement der Schachttüre in Kontakt gelangen. Dies ist dann der Fall, wenn sich die Aufzugskabine infolge einer Betriebsstörung nicht auf korrekt auf dem Niveau eines Stockwerks befindet.In the preferred embodiment of the invention take in existing coupling position of the adjusting elements and lack of contact force from the coupling element to the Mitnehmerkufe mounted on the joint pieces, the articulated pieces and their associated Mitnehmerkufe due to their weight or a spring force defined by one of the attacks weight or spring-centered Position in which none of the components of the device acts on the car door lock. This ensures that no unlocking of the car door takes place when the Mitnehmerkufen not reach the coupling process (Mitnehmerspreizung) with a coupling element of the shaft door in contact. This is the case when the elevator car is not on the level of a floor due to a malfunction.
Die Verstellelemente, die Gelenkstücke und die erste Mitnehmerkufe sind so gestaltet und angeordnet, dass bei vorhandener Kopplungsstellung der Verstellelemente die Gelenkstücke eine Stellung einnehmen, die bewirkt, dass eine vom Kopplungselement auf die mit ihnen gelenkig verbundene erste Mitnehmerkufe wirkende Kontaktkraft eine Zusatzbewegung der Gelenkstücke und der Mitnehmerkufe bewirkt, in deren Verlauf eine der Komponenten der Einrichtung einen Riegel der Kabinentürverriegelung entriegelt.The adjusting elements, the joint pieces and the first Mitnehmerkufe are designed and arranged so that occupy a position in the existing coupling position of the adjusting the articulated pieces, which causes a coupling element on the articulated connected to them first Mitnehmerkufe contact force an additional movement of the joint pieces and the Mitnehmerkufe effected, in the course of which one of the components of the device unlocks a bolt of the car door lock.
Gemäss einer bevorzugten Ausführungsform der Erfindung entriegelt die an den Gelenkstücken gelagerte Mitnehmerkufe oder ein mit ihr verbundenes Entriegelungsstück den Riegel der Kabinentürverriegelung. Die hat den Vorteil, dass die Lage des Riegels entlang der relativ langen Mitnehmerkufen variieren kann.According to a preferred embodiment of the invention, the Mitnehmerkufe mounted on the joint pieces or an unlocking piece connected to it unlocks the bolt of the car door lock. The advantage of this is that the position of the bolt along the relatively long Mitnehmerkufen can vary.
Nach einer zweckmässigen Ausgestaltung der Erfindung ist der Riegel der Kabinentürverriegelung ein um eine mit dem Kabinentürflügel verbundene Achse schwenkbarer zweiarmiger Hebel, der am einen Arm einen mit einem Verriegelungsanschlag zusammenwirkenden Haken aufweist, und der am anderen Arm eine Rolle trägt, über die er durch die Mitnehmerkufe oder eine mit ihr verbundene Entriegelungsfahne aus dem Eingriff mit dem Verriegelungsanschlag bewegt wird.According to an advantageous embodiment of the invention, the bolt of the car door lock is an axis connected to the car door wing pivotable two-armed lever having a cooperating with a locking stop hook on one arm, and carries on the other arm a role, through which it passes through the Mitnehmerkufe or an unlocking tab connected to it is moved out of engagement with the locking stop.
Diese Ausgestaltung des Riegels ermöglicht es, die Zusatzbewegung der ersten Mitnehmerkufe optimal und mit geringen Reibungsverlusten in eine Entriegelungsbewegung des Riegels umzusetzen.This embodiment of the bolt makes it possible to implement the additional movement of the first Mitnehmerkufe optimally and with low friction losses in an unlocking movement of the bolt.

Der Kopplungsmechanismus 14 umfasst zwei parallel zur Fahrrichtung der Aufzugskabine ausgerichtete Mitnehmerkufen 15.1, 15.2, die auf zwei um je eine Schwenkachse 16 schwenkbaren Verstellelementen 17.1, 17.2 gelagert sind und durch Schwenken dieser Verstellelemente in ihrer gegenseitigen Distanz verstellbar sind, d. h. eine ungespreizte oder eine gespreizte Stellung einnehmen können.On the
An den Schachttürflügeln aller Stockwerkstüren sind jeweils zwei Kopplungselemente 18 - hier in Form von Kopplungsrollen - vorhanden, die so weit in den Schachtraum neben den Mitnehmerkufen 15.1, 15.2 hineinragen, dass diese im gespreizten Zustand seitwärts (horizontal) gerichtete Kräfte und Bewegungen auf die Kopplungselemente 18 und den korrespondierenden Schachttürflügel übertragen können, sofern die Aufzugskabine 1 sich im Bereich eines Stockwerkniveaus befindet. Die den dargestellten Kabinentürflügeln 5 zugeordneten Schachttürflügel sind aus Gründen der Übersichtlichkeit in allen vorliegenden Fig. nicht sichtbar, und die an den Schachttürflügeln angebrachten Kopplungselemente (Kopplungsrollen) 18 sind daher nur mittels sogenannter Phantomlinien dargestellt.At the landing door wings of all floor doors are two each Coupling elements 18 - here in the form of coupling rollers - present, which protrude so far into the shaft space next to Mitnehmerkufen 15.1, 15.2, that they can transmit sideways (horizontally) directed forces and movements in the spread state on the
Das Schwenken der Verstellelemente 17.1, 17.2, und somit die Verstellung der Distanz zwischen den Mitnehmerkufen 15.1, 15.2 erfolgt ebenfalls durch die Antriebseinheit 8 über das linear wirkende Antriebsmittel 9. Das Wirkungsprinzip der Distanzverstellung (Spreizung) ist im Zusammenhang mit
Üblicherweise erfolgt bei Beginn des Türöffnungsvorgangs durch die Einwirkung der Mitnehmerkufen 15.1, 15.2 auf mindestens eines der Kopplungselemente 18 eine hier nicht weiter beschriebene Entriegelung des Schachttürflügels.Usually takes place at the beginning of the door opening operation by the action of the Mitnehmerkufen 15.1, 15.2 on at least one of the
Die Schwenkbewegung des Riegels 25 ist in beiden Richtungen mittels Riegelanschlägen 30 und elastischen Anschlagpuffern 31 begrenzt und mittels einer Rückstellfeder 32 in Richtung auf die Verriegelungsstellung des Riegels vorgespannt.The pivoting movement of the
Der die Öffnungs- und Schliessbewegung des Kabinentürflügels 5 auf den korrespondierenden Schachttürflügel übertragende Kopplungsmechanismus 14 umfasst im Wesentlichen die folgenden Bauteile:
- eine erste Mitnehmerkufe 15.1 und eine zweite Mitnehmerkufe 15.2,
- zwei zweiarmige Verstellelemente 17.1, 17.2, die auf je einer auf der Grundplatte 13 gelagerten Schwenkachse 16 fixiert sind und durch das erwähnte lineare Antriebsmittel 9 der jeweiligen Situation entsprechend geschwenkt werden.
- zwei Gelenkstücke 20.1, 20.2, von denen jedes eine gelenkige Verbindung zwischen jeweils einem Arm der beiden Verstellelemente 17.1, 17.2 und der ersten Mitnehmerkufe 15.1 bilden,
- eine mit der ersten Mitnehmerkufe 15.1
fest verbundene Entriegelungsfahne 21, das eine Entriegelungsbewegung (Zusatzbewegung) der Mitnehmerkufe 15.1 auf eine am zweiten Arm 25.2 desRiegels 25angebrachte Entriegelungsrolle 28 der Kabinentürverriegelung überträgt.
- a first Mitnehmerkufe 15.1 and a second Mitnehmerkufe 15.2,
- two two-armed adjusting elements 17.1, 17.2, which are fixed to a respective mounted on the
base plate 13pivot axis 16 and are pivoted by the aforementioned linear drive means 9 of the respective situation. - two joint pieces 20.1, 20.2, each of which form an articulated connection between in each case one arm of the two adjusting elements 17.1, 17.2 and the first driving skid 15.1,
- one with the first Mitnehmerkufe 15.1 firmly connected
Entriegelungsfahne 21, which transmits a Entriegelungsbewegung (additional movement) of the Mitnehmerkufe 15.1 mounted on a second arm 25.2 of thebolt 25Entriegelungsrolle 28 of the car door lock.
Vor Beginn eines Türflügel-Öffnungsvorgangs, d. h. in der in
Die erste Mitnehmerkufe 15.1 ist über zwei Gelenkstücke 20.1, 20.2 mit zwei korrespondierenden Armen der beiden Verstellelemente 17.1 und 17.2 gelenkig verbunden, d. h., zwischen diesen beiden Armen der Verstellelemente existiert keine direkte Verbindung. Die Gelenkstücke nehmen in dieser Situation eine durch das Zusammenwirken der Verstellelement-Anschläge 17.1.1, 17.2.1 mit den ersten Gelenkstückanschlägen 20.1.1 und 20.2.1 und durch die Gewichtskraft der Mitnehmerkufe 15.1 definierte Stellung ein, in welcher eine auf die Mitnehmerkufe 15.1 wirkende Horizontalkraft keine Zusatzbewegung bewirken kann.The first Mitnehmerkufe 15.1 is articulated via two joint pieces 20.1, 20.2 with two corresponding arms of the two adjusting elements 17.1 and 17.2, d. h., there is no direct connection between these two arms of the adjusting elements. In this situation, the joint pieces assume a position defined by the interaction of the adjusting element stops 17.1.1, 17.2.1 with the first joint piece stops 20.1.1 and 20.2.1 and by the weight force of the driving skid 15.1, in which a position on the driving skid 15.1 acting horizontal force can cause no additional movement.
Bei Beginn des Türflügel-Öffnungsvorgangs bewegt sich das an der Verbindungsstelle 24 mit dem Verstellelement 17.1 gekoppelte linear wirkende Antriebsmittel 9 nach rechts, so dass die Verstellelemente 17.1, 17.2 - unterstützt durch eine nicht dargestellte Spreizfeder - im Gegenuhrzeigersinn zu drehen beginnen. Dadurch werden die Mitnehmerkufen 15.1, 15.2, voneinander gespreizt. Sobald die Mitnehmerkufen 15.1, 15.2 ihre maximal gespreizte Stellung erreicht haben, werden die Verstellelemente 17.1, 17.2 und die Mitnehmerkufen durch einen - hier nicht dargestellten - Mechanismus blockiert, so dass sich die Kraft des Antriebsmittels 9 auf den gesamten Kopplungsmechanismus 14 und damit auch auf den Kabinentürflügel 5 überträgt.At the beginning of the door leaf opening operation, coupled to the
Beim anschliessenden Türflügel-Schliessvorgang bewegt sich das über die Verbindungsstelle 24 mit dem durch einen Mechanismus blockierten ersten Verstellelement 17.1 verbundene Antriebsmittel 9 nach links. Infolge der Wirkung des hier nicht dargestellten Blockiermechanismus bleiben während der Schliessbewegung der Türflügel die Mitnehmerkufen 15.1, 15.2 gespreizt und der Riegel der Kabinentürverriegelung entriegelt. Kurz bevor der Kabinentürflügel 5 seine Geschlossen-Stellung erreicht hat, wird die Wirkung des die Stellung des Verstellelements 17.1 blockierenden Mechanismus aufgehoben, und das Antriebsmittel 9 schwenkt die Verstellelemente und die Mitnehmerkufen in die vorstehend im Zusammenhang mit
