Da sich die beiden Türflügel im Mittelbereich überlappen, muss beim Schließvorgang stets zuerst der Standflügel geschlossen sein, ehe der Gangflügel vollständig schließt, da ansonsten der Standflügel an der Überlappung des Gangflügels anstößt und die Tür teilweise geöffnet bleibt, was insbesondere bei Rauch- und Brandschutztüren unzulässig ist. Die Schließfolgeregelung weist daher eine vom Standflügel gesteuerte Feststellvorrichtung auf, welche bei geöffnetem Standflügel den Gangflügel in einer zumindest teilweise geöffneten Position feststellt, und so ein Schließen des Standflügels vor dem Gangflügel ermöglicht.Closing sequence controls are required for double-leaf revolving doors when the door leaves are provided with a door rebate, wherein the fixed leaf with its door rebate forms the stop for the active leaf. Since the two leaves overlap in the central region, the passive leaf must always be closed first before the active leaf closes completely, since otherwise the passive leaf abuts the overlap of the active leaf and the door remains partially open, which is inadmissible especially in the case of smoke and fire doors is. Therefore, the closing sequence control has a controlled by the fixed wing locking device, which detects the active leaf in an at least partially open position with open wing, and thus allows closing of the inactive leaf in front of the active leaf.

In this case, the force transmission can be determined by the choice of the point of application of the transmission element on the tilting element.
Das im Getriebe des standflügelseitigen Türantriebs angeordnete Auslöseelement ist auf der Abtriebswelle drehbar angeordnet und wirkt mit einer Wickelscheibe zusammen, die drehfest auf der Abtriebswelle angeordnet ist. Auf die Wickelscheibe wird beim Öffnen des Türflügels ein Seil oder Band aufgewickelt, das eine in der Federanordnung abgestützte Schließfeder spannt. Durch einen auf der Wickelscheibe angeordneten Mitnehmer ist das Auslöseelement in der Geschlossenstellung des Türflügels so verschwenkt, dass die gangflügelseitige Bremse gelöst ist, und ein Schließen des Gangflügels durch die Schließfeder des gangflügelseitigen Türantriebs möglich ist. Wird der Standflügel durch den Türantrieb geöffnet, so wird das Auslöseelement frei, und das an der gangflügelseitigen Bremse angeordnete Kippelement kippt durch die Rückstellkraft der Feder so, dass der Bremsbelag in Anlage mit der Bremstrommel gelangt und die Motorwelle in Schließrichtung feststellt. Das Auslöselement ist durch das Übertragungselement, beispielsweise einen Seilzug oder einer Stange, mit dem Kippelement zur Betätigung der Bremse wirkverbunden. Um das Betätigen der Bremse auch bei den unterschiedlichen Montagearten der Türantriebe einfach zu ermöglichen, kann das Übertragungselement wahlweise an zwei einander gegenüberliegenden Fortsätzen am Auslöseelement festgelegt werden, wodurch ohne Änderung an den Antrieben die folgerichtige Betätigung der Bremse erfolgt.The release element arranged in the gearbox of the door leaf-side door drive is rotatably mounted on the output shaft and cooperates with a winding disk which is arranged non-rotatably on the output shaft. On the winding disk a rope or band is wound up when opening the door leaf, which tensions a closing spring supported in the spring arrangement. By arranged on the winding disc driver, the trigger element is pivoted in the closed position of the door so that the gangway side brake is released, and closing the active leaf by the closing spring of the gangway side door drive is possible. If the inactive leaf is opened by the door drive, the triggering element becomes free, and the tilting element arranged on the gangway-side brake tilts through the restoring force of the spring so that the brake lining comes into contact with the brake drum and locks the motor shaft in the closing direction. The trigger element is operatively connected by the transmission element, such as a cable or a rod, with the tilting element for actuating the brake. In order to enable easy operation of the brake even with the different types of installation of the door drives, the transmission element can be set optionally on two opposite projections on the trigger element, which is carried out without changing the drives, the logical operation of the brake.
Wie es bereits vorstehend beschrieben ist, ist auch bei festgestellter Bremse ein Öffnen des Gangflügels durch den auf der Motorwelle angeordneten Freilauf möglich. Eine Beschädigung der Türanlage durch eine unsachgemäße manuelle Betätigung des festgestellten Gangflügels wird vermieden, indem die Bremse so ausgelegt ist, dass bei Überlast der Bremsbelag auf der Bremstrommel durchrutschen kann.As already described above, opening of the active leaf is possible even when the brake is detected by the arranged on the motor shaft freewheel. Damage to the door system due to improper manual operation of the detected active leaf is avoided by designing the brake is that in case of overload, the brake pad can slip on the brake drum.

Die
Die Türantriebe 3, 4 können auf der Bandseite, der Seite auf der die Türbänder angeordnet sind, oder auf deren Gegenseite, der sogenannten Bandgegenseite, angeordnet sein. Bei einer Montage auf der Bandgegenseite greifen die den Türantrieben 3, 4 zugeordneten Gleitarme 13, 13' unter der Türumrahmung durch. Um die zur Türöffnung erforderliche richtige Drehrichtung der Abtriebswelle 10, 10' zu nutzen, wird der Türantrieb 3, 4 abhängig von der Montage auf der Band- oder Bandgegenseite um 180° gedreht montiert. Die Abtriebswelle 10, 10' ist dazu beiderseits des Getriebes 8 zur Montage des Gleitarms 13 oder des Gestänges zugänglich. Bei einer Montage der Türantriebe 3, 4 auf der Bandseite weisen die Antriebsmotoren 6 aufeinander zu, während diese bei einer Montage auf der Bandgegenseite von einander weg weisen.The door drives 3, 4 can be arranged on the hinge side, the side on which the door hinges are arranged, or on the opposite side, the so-called hinge opposite side.

Die Bremse 17 ist an der getriebeabgewandten Seite am Motorgehäuse des Antriebsmotors 6 des Türantriebs 3 angeordnet. Die aus dem Motorgehäuse herausgeführte Motorwelle 7 ist in einer Halterung 24 gelagert. Zwischen der Halterung 24 und dem Motorgehäuse ist auf der Motorwelle 7 ein Freilauf 21 festgelegt, auf dem eine Bremstrommel 22 drehfest angeordnet ist. Der Freilauf 21 bewirkt, dass bei geöffnetem Standflügel 2 und damit bei festgestellter Bremse 17, ein weiteres Öffnen des Gangflügels 1 möglich ist. An der Halterung 24 ist weiterhin ein Drehgeber 33 angeordnet, der mit einem an der Motorwelle 7 angeordneten Magneten 34 zur Steuerung der Türantriebs 3 zusammenwirkt.The
Zwischen der Halterung 24 und der Bremstrommel 22 ist der Bremsbelag 23 und ein plattenförmiges Kippelement 25 angeordnet. Der frei drehbar um die Motorwelle 7 angeordnete Bremsbelag 23 ist mit einer Feder 27 beaufschlagt, die sich an der Halterung 24 abstützt und den Bremsbelag 23 gegen die Bremstrommel 22 zur Feststellung der Motorwelle 7 beaufschlagt. Dazu weist das Kippelement 25 eine Aussparung 29 auf, durch welche die Feder 27 greifen kann.Between the
Die Bremstrommel 22 weist stirnseitig eine kreisförmig angeordnete, V-förmige Vertiefung auf, in welche der komplementär ausgebildete V-förmige Bremsbelag 23 eingreift. Der V-förmige Bremsbelag 23 kann an seiner Spitze abgeflacht sein, um eine Abnutzung der Reibbeläge zu kompensieren, wodurch der Bremsbelag 23 auch nach Abnutzung noch vollflächig anliegt. Weiterhin ist durch die V-Form die Reibfläche gegenüber einer flachen Form vergrößert, wodurch größere Bremskräfte möglich sind.The
An der Halterung 24 sind an einander gegenüberliegenden Seiten der Motorwelle 7 bzw. der Feder 27 senkrecht zueinander zwei Stifte 26 festgelegt, die das Kippelement 25 halten, indem die Stifte 26 an den Enden Verdickungen aufweisen. Das Kippelement 25 weist zwei entsprechende Aussparungen 35 auf, die im Durchmesser größer sind als die Stifte 26, so dass das Kippelement 25 gekippt werden kann, wie es in den
Weiterhin weist das Kippelement 25 eine Aufnahme 36 auf, in welcher das Übertragungselement 18 aufgenommen ist. Aufgrund der möglichen, unterschiedlichen Montagearten der Türantriebe 3, 4 kann das Kippelement 25 zur wahlweisen Anordnung des Übertragungselements 18 mehrere Aufnahmen 36 aufweisen. Dabei kann ein Klemmelement 20 auf dem Übertragungselement 18 angeordnet sein, an dem sich das Kippelement 25 bei einer Betätigung abstützt, wie es in

Bei unbestromtem Antriebsmotor 6 kann sich somit die Motorwelle 7 sowie das mit dieser verbundene Getriebe 8 mit der Abtriebswelle 10 frei drehen. Damit kann die beim Öffnen des Gangflügels 1 gespannte Feder der Federanordnung 9 eine Drehbewegung der Abtriebswelle 10 in Schließrichtung des Gangflügels 1 bewirken.In the case of a
Das Auslöseelement 19 zur Regelung der Schließfolge ist im Getriebe 8 des standflügelseitigen Türantriebs 4 angeordnet. Die mit der Abtriebswelle 10' drehfest verbundene Wickelscheibe 15 weist einen Mitnehmer 29 auf, der in einer zumindest annähernd halbreisförmig im Auslöseelement 19 angeordneten Führung 32 bewegbar ist. Das Auslöseelement 19 weist gegenüberliegende Schwenkhebel 30, 30' auf, an welchen das Übertragungselement 18 wahlweise - abhängig von der Montageart des Türantriebs 3, 4 auf der Bandseite oder Bandgegenseite - festgelegt werden kann, wodurch ohne Änderung an den Türantrieben 3, 4 die folgerichtige Betätigung der Bremse 17 erfolgt. Um das Übertragungselement 18 bei auf der Bandseite montierten Türantrieben 3, 4 mit dem Auslöseelement 19 in Wirkverbindung zu bringen, ist ein Zwischenstück 31 angeordnet, das die Befestigungsstelle aus dem Getriebe 8 herausführt. Bei der Montage auf der Bandgegenseite ist dies nicht erforderlich, da durch einen abnehmbaren Deckel am Getriebe 8 der obere Schwenkhebel 30 zugänglich ist. Befindet sich der Standflügel 2 in seiner Geschlossenlage, ist die Feder in der Federanordnung 9 entspannt. Die auf der Abtriebswelle 10 drehfest angeordnete Wickelscheibe 15 befindet sich in der in
