Definitions

  • the invention relates to a door system for an elevator installation and an elevator installation with such a door system.
  • Elevator systems are usually arranged in an elevator shaft that connects several floors.
  • the elevator shaft has shaft door openings at the height of the individual floors.
  • Shaft doors are arranged at these shaft door openings.
  • the elevator system includes an elevator car, which is arranged to be movable within the elevator shaft.
  • the elevator car has a car door opening.
  • a car door is arranged at this car door opening.
  • Both the shaft doors and the at least one car door usually each have at least one door leaf.
  • EP 2 088 273 A1 shows an opening and closing mechanism for an elevator door designed as a folding door.
  • the elevator door comprises a door drive, a belt coupled to the door drive and a linkage connected to this belt.
  • the folding door includes a leading and a trailing door leaf.
  • the door drive comprises a motor and is coupled to the leading door leaf by means of the linkage in such a way that when the motor shaft rotates, the leading door leaf is pivoted out of its door-closing plane and the door is then opened. If the door leaves are arranged in their door-closing plane, the elevator door is considered to be locked due to the functionality of the linkage under the influence of the holding current of the motor.
  • the disadvantage is that the mechanism of such a door system is complicated and electrical energy is required to lock the door.
  • a door system for an elevator system includes a drive unit with a driven, pivoted shaft and a blocking element, wherein the blocking element is fixed to the shaft, at least one pivot unit, each of the at least one pivot unit comprising a pivot axis that can be coupled to a door leaf and a blocking recess, the blocking recess being fixed to the pivot axis, a pivot movement of the pivot axis being controlled by a first end position describing an end position of the door system is limited, the blocking element interacting with the blocking recess in such a way that the blocking element engages in the blocking recess and the pivot axis can thus be blocked in the first end position.
  • a first of the end positions corresponds to the open position of the door system, a second of these end positions corresponds to the closed position of the door system.
  • a door system of an elevator installation can include both a car door and a shaft door, which are spaced apart from one another in the closed position of the door system, preferably by means of a door sill gap.
  • the drive unit comprising the shaft can accordingly be part of the car door or the shaft door, with the pivot axis being able to be a part of the car door or the shaft door independently of this.
  • the invention is based on the development that the pivot axis which can be coupled to the door leaf and whose pivoting movement causes an opening or closing movement of the door leaf may be locked in at least one of its two end positions.
  • a pivoting movement is a rotating movement, in which case it is not possible to carry out a complete revolution in one direction of rotation.
  • the pivot axis has a maximum angle of rotation of less than 360° at any point in time within a period of time, which preferably includes an entire door opening and door closing process.
  • pivot axis cannot be pivoted or rotated through 360° or beyond during the door opening or door closing processes. Starting from a position of the pivot axis corresponding to the closed position of the door system, the pivot axis is therefore at none Time panned 360° or beyond.
  • the blocking element attached to the driven shaft of the door drive engages in the blocking recess attached to the pivot axis and thus prevents an undesired opening or closing movement of the door leaf, preferably by means of a form fit.
  • a form fit as mentioned in this description can be achieved, for example, in that the blocking element is formed by a circular section of a circular disk arranged perpendicularly to the shaft, the associated circle center point of this circular section being arranged on the axis of the shaft belonging to the door drive.
  • the locking recess fixed to the associated pivot axis has a circular section. In the end position of the pivot axis, this circular section is positively adjacent to the circular arc of the circular section belonging to the blocking element, so that when the shaft is in the open or closed position of the door system, a pivoting movement of the pivot axis is prevented.
  • a form fit as mentioned in this description can also be achieved, for example, by forming the blocking element from one or at least two pin(s) engaging in the blocking recess and thus preventing the pivoting movement of the pivot axis from the end position.
  • the blocking element and the blocking recess interacting with this blocking element are designed in such a way that blocking of the pivot axis provided with the blocking recess is prevented during the pivoting movement of the pivot axis out of the blocking recess.
  • the interaction of the shaft with the pivot axis means that no additional control arrangement is required which uses a signal to unblock or unlock the door leaf before the opening or closing movement of the door leaf is completed.
  • one of the at least one pivoting unit is designed as a primary pivoting unit, with the primary pivoting unit comprising a second locking recess fixed to the pivoting axis of the primary pivoting unit, with the pivoting movement of the pivoting axis belonging to the primary pivoting unit being controlled by a second end position describing an end position of the door system is limited and the blocking element acts on the second blocking recess fixed to the pivot axis of the primary pivot unit in such a way that the pivot axis of the primary pivot unit can be blocked in its second end position.
  • the door leaf of the pivoting door can be blocked both in its open and in its closed position. Accordingly, a further locking device is not necessary, which allows the door leaf to be locked in the open or closed position.
  • the door system can comprise a car door and a shaft door, with the car door and the shaft door being spaced apart from one another when the door system is in the closed position, preferably by means of a door sill gap, with a first of the doors comprising the car door and the shaft door comprising the drive unit and the primary pivoting unit.
  • a first of the doors comprising the car door and the shaft door comprising the drive unit and the primary pivoting unit.
  • the drive unit can include a first driver means and the primary pivoting unit can include a counter-element that can be actuated by the first driver means, with the first driver means being fixed to the shaft and the counter-element of the primary pivot unit to the pivot axis of the primary pivot unit in such a way that the driver means a Causes pivoting movement of the pivot axis and a pivoting movement of the door leaf can be effected. In this way there is a possibility that both locking and pivoting of the door leaf can be achieved by means of the shaft and the pivot axis.
  • a further development of the door system comprises a car door and a shaft door, with the car door and the shaft door being spaced apart from one another when the door system is in the closed position, preferably by means of a door sill gap, with one of the at least one pivoting unit being designed as a secondary pivoting unit, with one or the first of the doors comprising the car door and the shaft door comprises the drive unit and the second of the doors comprising the car door and the shaft door comprises the secondary pivoting unit, the on the locking element fixed to the shaft acts on the locking recess of the secondary pivoting unit in such a way that the pivoting axis of the secondary pivoting unit can be blocked in its end position corresponding to the open position of the door system.
  • the secondary swivel unit is the swivel unit that is not arranged on the drive side. If the drive unit is part of the car door, then such a “secondary pivoting unit” is part of the shaft door. As an alternative to this, such a “secondary pivoting unit” is part of the car door if the drive unit is part of the shaft door.
  • the second of the doors comprising the car door and the shaft door can comprise a gear unit, with the gear unit comprising a further locking element, with the locking element of the gear unit interacting with the locking recess of the secondary pivoting unit in such a way that the pivoting axis of the secondary pivoting unit is in its end position corresponding to the closed position of the door system is blockable.
  • the gear unit can include a counter-element that can be actuated by the first entrainment means, with the blocking element of the gear unit and the locking recess of the secondary pivoting unit being designed in such a way that a blocking of the pivot axis of the secondary pivot unit can be canceled by actuating the counter-element of the gear unit by the first entrainment means. In this way, it is possible to lock or unlock the door leaf coupled to the pivot axis of the secondary pivot unit. During a pivoting movement of the pivot axis belonging to the secondary pivot unit, the locking element of the gear unit is pivoted out of the locking recess of the secondary pivot unit.
  • the drive unit can comprise a second entrainment means and the secondary pivoting unit can comprise a further counter-element that can be actuated by the second entrainment means, with the second entrainment means being fixed to the shaft and the counter-element of the secondary pivoting unit to the pivot axis of the secondary pivoting unit in such a way that the second entrainment means can be rotated during a pivoting movement of the wave one causess a pivoting movement of the pivot axis of the secondary pivot unit and a pivoting movement of the door leaf that can be coupled to the pivot axis can be effected.

  • first and second entrainment means and the counter-elements fixed to the pivot axes can be fixed to the shaft or to the pivot axes in such a way that the pivot movements of the pivot axes of the primary and secondary pivot units take place essentially at the same time when the door system is opened or closed. In this way, a simple coupling of the car door to the landing door is made possible during the opening and closing movement of the door system. Accordingly, an additional device for synchronizing the movement of the shaft and car door panels is not necessary.
  • At least one door leaf can be pivotably arranged on the pivot axis assigned to this door leaf. Accordingly, the driven shaft of the door drive acts directly on the pivot axis of the door leaf, after which additional mechanically acting coupling elements between the shaft and the pivot axis can be dispensed with.
  • a further development of the door system is designed as a folding door system.
  • Such a door system designed as a folding door system has the advantage that the door system requires little space in a direction perpendicular to the door closing plane.
  • the shaft and/or the at least one pivot axis can be arranged essentially vertically along the elevator shaft or vertically in the elevator shaft.
  • the vertical arrangement of the shaft or the at least one pivot axis in the elevator shaft has the advantage that a space-saving arrangement of the drive unit or pivot axis is made possible, since it can easily be stowed in the doorpost or in the immediate vicinity of the doorpost.
  • an output shaft of a motor of the drive unit and the driven, pivotably mounted shaft are arranged coaxially with one another.

Description

Die Erfindung betrifft ein Türsystem für eine Aufzugsanlage und eine Aufzugsanlage mit einem solchen Türsystem.The invention relates to a door system for an elevator installation and an elevator installation with such a door system.

Aufzugsanlagen sind üblicherweise in einem Aufzugsschacht angeordnet, der mehrere Stockwerke verbindet. Der Aufzugsschacht weist auf der Höhe der einzelnen Stockwerke Schachttüröffnungen auf. An diesen Schachttüröffnungen sind Schachttüren angeordnet. Die Aufzugsanlage umfasst eine Aufzugskabine, die innerhalb des Aufzugsschachtes verfahrbar angeordnet ist. Die Aufzugskabine weist eine Kabinentüröffnung auf. An dieser Kabinentüröffnung ist eine Kabinentür angeordnet. Sowohl die Schachttüren, als auch die mindestens eine Kabinentür weisen üblicherweise jeweils mindestens ein Türblatt auf.Elevator systems are usually arranged in an elevator shaft that connects several floors. The elevator shaft has shaft door openings at the height of the individual floors. Shaft doors are arranged at these shaft door openings. The elevator system includes an elevator car, which is arranged to be movable within the elevator shaft. The elevator car has a car door opening. A car door is arranged at this car door opening. Both the shaft doors and the at least one car door usually each have at least one door leaf.

EP 2 088 273 A1 zeigt einen Öffnungs- und Schliessmechanismus für eine als Falttür ausgebildete Aufzugstür. Die Aufzugstür umfasst einen Türantrieb, einen mit dem Türantrieb gekoppelten Riemen und ein mit diesem Riemen verbundenes Koppelgetriebe. Zudem umfasst die Falttür ein voreilendes und ein nacheilendes Türblatt. Der Türantrieb umfasst einen Motor und ist derart mit dem voreilenden Türblatt mittels des Koppelgetriebes gekoppelt, dass bei einer Rotation der Motorwelle das voreilende Türblatt aus seiner Türschliessebene geschwenkt und anschliessend die Türe geöffnet wird. Bei einer Anordnung der Türblätter in ihrer Türschliessebene gilt die Aufzugstür aufgrund der Funktionalität des Koppelgetriebes unter dem Einfluss des Haltestromes des Motors als verriegelt. Nachteilig ist, dass die Mechanik eines solchen Türsystems kompliziert und zur Verriegelung der Tür elektrische Energie vonnöten ist. EP 2 088 273 A1 shows an opening and closing mechanism for an elevator door designed as a folding door. The elevator door comprises a door drive, a belt coupled to the door drive and a linkage connected to this belt. In addition, the folding door includes a leading and a trailing door leaf. The door drive comprises a motor and is coupled to the leading door leaf by means of the linkage in such a way that when the motor shaft rotates, the leading door leaf is pivoted out of its door-closing plane and the door is then opened. If the door leaves are arranged in their door-closing plane, the elevator door is considered to be locked due to the functionality of the linkage under the influence of the holding current of the motor. The disadvantage is that the mechanism of such a door system is complicated and electrical energy is required to lock the door.

Daher ist es Aufgabe der Erfindung, ein Türsystem für eine Aufzugsanlage vorzuschlagen, welches einen einfachen Aufbau aufweist und zudem einen kostengünstigen Betrieb ermöglicht.It is therefore the object of the invention to propose a door system for an elevator installation which has a simple structure and also enables cost-effective operation.

Die Aufgabe wird gelöst durch ein Türsystem für eine Aufzugsanlage, das Türsystem umfasst eine Antriebseinheit mit einer angetriebenen, schwenkbar gelagerten Welle und einem Sperrelement, wobei das Sperrelement an der Welle fixiert ist, mindestens eine Schwenkeinheit, wobei eine jede der mindestens einen Schwenkeinheit eine mit einem Türblatt koppelbare Schwenkachse und eine Sperrausnehmung umfasst, wobei die Sperrausnehmung an der Schwenkachse fixiert ist, wobei eine Schwenkbewegung der Schwenkachse durch eine erste eine Endstellung des Türsystems beschreibende Endposition begrenzt ist, wobei das Sperrelement derart mit der Sperrausnehmung zusammenwirkt, dass das Sperrelement in die Sperrausnehmung eingreift und so die Schwenkachse in der ersten Endposition blockierbar ist.The object is achieved by a door system for an elevator system, the door system includes a drive unit with a driven, pivoted shaft and a blocking element, wherein the blocking element is fixed to the shaft, at least one pivot unit, each of the at least one pivot unit comprising a pivot axis that can be coupled to a door leaf and a blocking recess, the blocking recess being fixed to the pivot axis, a pivot movement of the pivot axis being controlled by a first end position describing an end position of the door system is limited, the blocking element interacting with the blocking recess in such a way that the blocking element engages in the blocking recess and the pivot axis can thus be blocked in the first end position.

Die Aufgabe wird ebenso gelöst durch eine Aufzugsanlage mit einem solchen Türsystem. Eine erste der Endstellungen entspricht der Offenstellung des Türsystems, eine zweite dieser Endstellungen entspricht der Geschlossenstellung des Türsystems.The task is also solved by an elevator system with such a door system. A first of the end positions corresponds to the open position of the door system, a second of these end positions corresponds to the closed position of the door system.

Ein Türsystem einer Aufzugsanlage kann sowohl eine Kabinentür als auch eine Schachttür umfassen, die in der Geschlossenstellung des Türsystem vorzugsweise mittels eines Türschwellenspaltes voneinander beabstandet sind. Die die Welle umfassende Antriebseinheit kann demnach Bestandteil der Kabinentür oder der Schachttür sein, wobei die Schwenkachse unabhängig davon Bestandteil der Kabinentür oder der Schachttür sein kann.A door system of an elevator installation can include both a car door and a shaft door, which are spaced apart from one another in the closed position of the door system, preferably by means of a door sill gap. The drive unit comprising the shaft can accordingly be part of the car door or the shaft door, with the pivot axis being able to be a part of the car door or the shaft door independently of this.

Die Erfindung basiert auf der Entwicklung, dass die mit dem Türblatt koppelbare Schwenkachse, deren Schwenkbewegung eine Öffnungs- bzw. Schliessbewegung des Türblattes bewirkt, in mindestens einer ihrer beiden Endpositionen verriegelt werden darf. Durch die Blockierung der das Türblatt schwenkenden Schwenkachse kann demnach das Türblatt bzw. die Tür in der Geschlossen- bzw. Offenstellung verriegelt werden. Eine solche Schwenkbewegung ist eine rotierende Bewegung, wobei in einer Drehrichtung keine vollständige Umdrehung ausführbar ist. Die Schwenkachse weist demzufolge ausgehend von der ersten Endposition zu jedem Zeitpunkt innerhalb eines Zeitraumes, welcher vorzugsweise einen gesamten Türöffnungs- und Türschliessvorgang umfasst, einen maximalen Drehwinkel von weniger als 360° auf. Das heisst, dass die Schwenkachse während der Türöffnungs- bzw. Türschliessvorgänge nicht 360° bzw. darüber hinaus schwenk- bzw. rotierbar ist. Ausgehend von einer Stellung der Schwenkachse entsprechend der Geschlossenstellung des Türsystems ist die Schwenkachse demzufolge zu keinem Zeitpunkt 360° bzw. darüber hinaus geschwenkt.The invention is based on the development that the pivot axis which can be coupled to the door leaf and whose pivoting movement causes an opening or closing movement of the door leaf may be locked in at least one of its two end positions. By blocking the pivot axis pivoting the door leaf, the door leaf or the door can be locked in the closed or open position. Such a pivoting movement is a rotating movement, in which case it is not possible to carry out a complete revolution in one direction of rotation. As a result, starting from the first end position, the pivot axis has a maximum angle of rotation of less than 360° at any point in time within a period of time, which preferably includes an entire door opening and door closing process. This means that the pivot axis cannot be pivoted or rotated through 360° or beyond during the door opening or door closing processes. Starting from a position of the pivot axis corresponding to the closed position of the door system, the pivot axis is therefore at none Time panned 360° or beyond.

Dabei greift das an der angetriebenen Welle des Türantriebs angebrachte Sperrelement in die an der Schwenkachse angebrachte Sperrausnehmung ein und verhindert damit vorzugsweise mittels eines Formschlusses eine unerwünschte Öffnungs- bzw. Schliessbewegung des Türblattes.The blocking element attached to the driven shaft of the door drive engages in the blocking recess attached to the pivot axis and thus prevents an undesired opening or closing movement of the door leaf, preferably by means of a form fit.

Ein gemäss dieser Beschreibung erwähnter Formschluss kann beispielhaft dadurch erreicht werden, dass das Sperrelement durch einen Kreisabschnitt einer senkrecht zur Welle angeordneten kreisrunden Scheibe gebildet ist, wobei der zugehörige Kreismittelpunkt dieses Kreisabschnittes auf der Achse der zum Türantrieb gehörigen Welle angeordnet ist. Die an der zugehörigen Schwenkachse fixierte Sperrausnehmung weist in diesem Fall einen kreisförmigen Abschnitt auf. Dieser kreisförmige Abschnitt grenzt in der Endposition der Schwenkachse formschlüssig am Kreisbogen des zum Sperrelement gehörigen Kreisabschnittes an, so dass bei der der Offen- bzw. Geschlossenstellung des Türsystems entsprechenden Stellung der Welle eine Schwenkbewegung der Schwenkachse verhindert ist. Ein gemäss dieser Beschreibung erwähnter Formschluss kann beispielhaft ebenso dadurch erreicht, dass das Sperrelement beispielhaft aus einem oder mindestens zwei in die Sperrausnehmung eingreifenden Stift(en) gebildet ist und derart die Schwenkbewegung der Schwenkachse aus der Endposition verhindert ist.A form fit as mentioned in this description can be achieved, for example, in that the blocking element is formed by a circular section of a circular disk arranged perpendicularly to the shaft, the associated circle center point of this circular section being arranged on the axis of the shaft belonging to the door drive. In this case, the locking recess fixed to the associated pivot axis has a circular section. In the end position of the pivot axis, this circular section is positively adjacent to the circular arc of the circular section belonging to the blocking element, so that when the shaft is in the open or closed position of the door system, a pivoting movement of the pivot axis is prevented. A form fit as mentioned in this description can also be achieved, for example, by forming the blocking element from one or at least two pin(s) engaging in the blocking recess and thus preventing the pivoting movement of the pivot axis from the end position.

Bei einer Weiterbildung des Türsystems sind das Sperrelement und die mit diesem Sperrelement zusammenwirkende Sperrausnehmung derart ausgebildet, dass eine Blockierung der mit der Sperrausnehmung versehenen Schwenkachse während der Schwenkbewegung der Schwenkachse aus der Sperrausnehmung verhindert ist. Derart kann erreicht werden, dass durch das Zusammenwirken der Welle mit der Schwenkachse keine zusätzliche Steueranordnung vonnöten ist, die mittels eines Signals eine Deblockierung bzw. Entriegelung des Türblattes bewirkt, bevor die Öffnungs- bzw. Schliessbewegung des Türblattes vollzogen wird.In a further development of the door system, the blocking element and the blocking recess interacting with this blocking element are designed in such a way that blocking of the pivot axis provided with the blocking recess is prevented during the pivoting movement of the pivot axis out of the blocking recess. In this way it can be achieved that the interaction of the shaft with the pivot axis means that no additional control arrangement is required which uses a signal to unblock or unlock the door leaf before the opening or closing movement of the door leaf is completed.

Bei einer Weiterbildung des Türsystems ist eine der mindestens einen Schwenkeinheit als Primärschwenkeinheit ausgebildet ist, wobei die Primärschwenkeinheit eine zweite an der Schwenkachse der Primärschwenkeinheit fixierte Sperrausnehmung umfasst, wobei die Schwenkbewegung der zur Primärschwenkeinheit gehörigen Schwenkachse durch eine zweite eine Endstellung des Türsystems beschreibende Endposition begrenzt ist und das Sperrelement derart auf die an der Schwenkachse der Primärschwenkeinheit fixierte zweite Sperrausnehmung wirkt, dass die Schwenkachse der Primärschwenkeinheit in ihrer zweiten Endposition blockierbar ist. Derart kann das Türblatt der Schwenktür sowohl in seiner Offen-, als auch in seiner Geschlossenstellung blockiert werden. Demnach ist eine weitere Verriegelungsvorrichtung nicht notwendig, welche die Verriegelung des Türblattes in der Offen- bzw. Geschlossenstellung ermöglicht.In a further development of the door system, one of the at least one pivoting unit is designed as a primary pivoting unit, with the primary pivoting unit comprising a second locking recess fixed to the pivoting axis of the primary pivoting unit, with the pivoting movement of the pivoting axis belonging to the primary pivoting unit being controlled by a second end position describing an end position of the door system is limited and the blocking element acts on the second blocking recess fixed to the pivot axis of the primary pivot unit in such a way that the pivot axis of the primary pivot unit can be blocked in its second end position. In this way, the door leaf of the pivoting door can be blocked both in its open and in its closed position. Accordingly, a further locking device is not necessary, which allows the door leaf to be locked in the open or closed position.

Zusätzlich kann das Türsystem eine Kabinentür und eine Schachttür umfassen, wobei die Kabinentür und die Schachttür bei einer Geschlossenstellung des Türsystems vorzugsweise mittels eines Türschwellenspaltes voneinander beabstandet anordenbar sind, wobei eine erste der die Kabinentür und die Schachttür umfassenden Türen die Antriebseinheit und die Primärschwenkeinheit umfasst. Derart ist eine einfache und sichere Anordnung des Türsystems in einer Aufzugsanlage ermöglicht. Wenn die Antriebseinheit Bestandteil der Kabinentür ist, ist demnach eine solche "Primärschwenkeinheit" ebenso Bestandteil dieser Kabinentür. Alternativ dazu ist eine solche "Primärschwenkeinheit" Bestandteil der Schachttür, wenn die Antriebseinheit Bestandteil der Schachttür ist.In addition, the door system can comprise a car door and a shaft door, with the car door and the shaft door being spaced apart from one another when the door system is in the closed position, preferably by means of a door sill gap, with a first of the doors comprising the car door and the shaft door comprising the drive unit and the primary pivoting unit. In this way, a simple and safe arrangement of the door system in an elevator installation is made possible. If the drive unit is part of the car door, then such a "primary pivoting unit" is also a part of this car door. As an alternative to this, such a "primary pivoting unit" is part of the shaft door if the drive unit is part of the shaft door.

Zusätzlich kann die Antriebseinheit ein erstes Mitnahmemittel umfassen und die Primärschwenkeinheit ein durch das erste Mitnahmemittel betätigbares Gegenelement umfassen, wobei das erste Mitnahmemittel an der Welle und das Gegenelement der Primärschwenkeinheit an der Schwenkachse der Primärschwenkeinheit derart fixiert sind, dass das Mitnahmemittel bei einer Schwenkbewegung der Welle eine Schwenkbewegung der Schwenkachse bewirkt und eine Schwenkbewegung des Türblattes bewirkbar ist. Derart ist eine Möglichkeit gegeben, dass sowohl eine Verriegelung als auch eine Verschwenkung des Türblattes mittels der Welle und der Schwenkachse erreicht werden kann.In addition, the drive unit can include a first driver means and the primary pivoting unit can include a counter-element that can be actuated by the first driver means, with the first driver means being fixed to the shaft and the counter-element of the primary pivot unit to the pivot axis of the primary pivot unit in such a way that the driver means a Causes pivoting movement of the pivot axis and a pivoting movement of the door leaf can be effected. In this way there is a possibility that both locking and pivoting of the door leaf can be achieved by means of the shaft and the pivot axis.

Eine Weiterbildung des Türsystems umfasst eine bzw. die Kabinentür und eine bzw. die Schachttür, wobei die Kabinentür und die Schachttür bei einer Geschlossenstellung des Türsystems vorzugsweise mittels eines Türschwellenspaltes voneinander beabstandet anordenbar sind, wobei eine der mindestens einen Schwenkeinheit als Sekundärschwenkeinheit ausgebildet ist, wobei eine bzw. die erste der die Kabinentür und die Schachttür umfassenden Türen die Antriebseinheit umfasst und die zweite der die Kabinentür und die Schachttür umfassenden Türen die Sekundärschwenkeinheit umfasst, wobei das an der Welle fixierte Sperrelement derart auf die Sperrausnehmung der Sekundärschwenkeinheit wirkt, dass die Schwenkachse der Sekundärschwenkeinheit in ihrer der Offenstellung des Türsystems entsprechenden Endposition blockierbar ist. Derart ist ermöglicht, dass die Kabinentür bzw. Schachttür des Türsystems, welche nicht antriebsseitig angeordnet ist, ebenso mittels der antriebsseitigen Welle blockiert werden kann. Definitionsgemäss ist die Sekundärschwenkeinheit die nicht antriebsseitig angeordnete Schwenkeinheit. Wenn die Antriebseinheit Bestandteil der Kabinentür ist, ist demnach eine solche "Sekundärschwenkeinheit" Bestandteil der Schachttür. Alternativ dazu ist eine solche "Sekundärschwenkeinheit" Bestandteil der Kabinentür, wenn die Antriebseinheit Bestandteil der Schachttür ist.A further development of the door system comprises a car door and a shaft door, with the car door and the shaft door being spaced apart from one another when the door system is in the closed position, preferably by means of a door sill gap, with one of the at least one pivoting unit being designed as a secondary pivoting unit, with one or the first of the doors comprising the car door and the shaft door comprises the drive unit and the second of the doors comprising the car door and the shaft door comprises the secondary pivoting unit, the on the locking element fixed to the shaft acts on the locking recess of the secondary pivoting unit in such a way that the pivoting axis of the secondary pivoting unit can be blocked in its end position corresponding to the open position of the door system. This makes it possible for the car door or shaft door of the door system, which is not arranged on the drive side, to also be blocked by means of the drive-side shaft. By definition, the secondary swivel unit is the swivel unit that is not arranged on the drive side. If the drive unit is part of the car door, then such a "secondary pivoting unit" is part of the shaft door. As an alternative to this, such a "secondary pivoting unit" is part of the car door if the drive unit is part of the shaft door.

Zusätzlich kann die zweite der die Kabinentür und die Schachttür umfassenden Türen eine Getriebeeinheit umfassen, wobei die Getriebeeinheit ein weiteres Sperrelement umfasst, wobei das Sperrelement der Getriebeeinheit derart mit der Sperrausnehmung der Sekundärschwenkeinheit zusammenwirkt, dass die Schwenkachse der Sekundärschwenkeinheit in ihrer der Geschlossenstellung des Türsystems entsprechenden Endposition blockierbar ist. Derart wird ermöglicht, dass sowohl die Kabinentür als auch die Schachttür in einer Geschlossenstellung des Türsystems verriegelt ist.In addition, the second of the doors comprising the car door and the shaft door can comprise a gear unit, with the gear unit comprising a further locking element, with the locking element of the gear unit interacting with the locking recess of the secondary pivoting unit in such a way that the pivoting axis of the secondary pivoting unit is in its end position corresponding to the closed position of the door system is blockable. This makes it possible for both the car door and the shaft door to be locked when the door system is in a closed position.

Zusätzlich kann die Getriebeeinheit ein durch das erste Mitnahmemittel betätigbares Gegenelement umfassen, wobei das Sperrelement der Getriebeeinheit und die Sperrausnehmung der Sekundärschwenkeinheit derart ausgebildet sind, dass eine Blockierung der Schwenkachse der Sekundärschwenkeinheit durch eine Betätigung des Gegenelementes der Getriebeeinheit durch das erste Mitnahmemittel aufhebbar ist. Derart ist eine Verriegelung bzw. Entriegelung des an die Schwenkachse der Sekundärschwenkeinheit gekoppelten Türblattes ermöglicht. Während einer Schwenkbewegung der zur Sekundärschwenkeinheit gehörigen Schwenkachse ist das Sperrelement der Getriebeeinheit aus der Sperrausnehmung der Sekundärschwenkeinheit ausgeschwenkt.In addition, the gear unit can include a counter-element that can be actuated by the first entrainment means, with the blocking element of the gear unit and the locking recess of the secondary pivoting unit being designed in such a way that a blocking of the pivot axis of the secondary pivot unit can be canceled by actuating the counter-element of the gear unit by the first entrainment means. In this way, it is possible to lock or unlock the door leaf coupled to the pivot axis of the secondary pivot unit. During a pivoting movement of the pivot axis belonging to the secondary pivot unit, the locking element of the gear unit is pivoted out of the locking recess of the secondary pivot unit.

Darüber hinaus kann die Antriebseinheit ein zweites Mitnahmemittel und die Sekundärschwenkeinheit ein weiteres durch das zweite Mitnahmemittel betätigbares Gegenelement umfassen, wobei das zweite Mitnahmemittel an der Welle und das Gegenelement der Sekundärschwenkeinheit an der Schwenkachse der Sekundärschwenkeinheit derart fixiert sind, dass das zweite Mitnahmemittel bei einer Schwenkbewegung der Welle eine Schwenkbewegung der Schwenkachse der Sekundärschwenkeinheit bewirkt und eine Schwenkbewegung des mit der Schwenkachse koppelbaren Türblattes bewirkbar ist. Derart wird ermöglicht, dass bei einer Schwenkbewegung der angetriebenen Welle sowohl die erste und die zweite Schwenkachse, also das Kabinentürblatt und das Schachttürblatt, geschwenkt werden können.In addition, the drive unit can comprise a second entrainment means and the secondary pivoting unit can comprise a further counter-element that can be actuated by the second entrainment means, with the second entrainment means being fixed to the shaft and the counter-element of the secondary pivoting unit to the pivot axis of the secondary pivoting unit in such a way that the second entrainment means can be rotated during a pivoting movement of the wave one Causes a pivoting movement of the pivot axis of the secondary pivot unit and a pivoting movement of the door leaf that can be coupled to the pivot axis can be effected. In this way, it is made possible for both the first and the second pivot axis, ie the car door panel and the shaft door panel, to be pivoted when the driven shaft is pivoted.

Zusätzlich kann das erste und das zweite Mitnahmemittel und die an den Schwenkachsen fixierten Gegenelemente derart an der Welle bzw. an den Schwenkachsen fixiert sein, dass die Schwenkbewegungen der Schwenkachsen der Primär- und der Sekundärschwenkeinheit im Wesentlichen zeitgleich beim Öffnen bzw. Schliessen des Türsystems erfolgen. Auf diese Weise ist eine einfache Kopplung der Kabinentür mit der Schachttür bei der Öffnungs- bzw. Schliessbewegung des Türsystems ermöglicht. Entsprechend ist eine zusätzliche Vorrichtung zum Synchronisieren der Bewegung des Schacht- und des Kabinentürblattes nicht notwendig.In addition, the first and second entrainment means and the counter-elements fixed to the pivot axes can be fixed to the shaft or to the pivot axes in such a way that the pivot movements of the pivot axes of the primary and secondary pivot units take place essentially at the same time when the door system is opened or closed. In this way, a simple coupling of the car door to the landing door is made possible during the opening and closing movement of the door system. Accordingly, an additional device for synchronizing the movement of the shaft and car door panels is not necessary.

Bei einer Weiterbildung des Türsystems mindestens ein Türblatt schwenkbar an der diesem Türblatt zugeordneten Schwenkachse anordenbar. Demnach wirkt die angetriebene Welle des Türantriebs direkt auf die Schwenkachse des Türblattes, wonach auf zusätzliche mechanisch wirkende Kopplungselemente zwischen der Welle und der Schwenkachse verzichtet werden kann.In a further development of the door system, at least one door leaf can be pivotably arranged on the pivot axis assigned to this door leaf. Accordingly, the driven shaft of the door drive acts directly on the pivot axis of the door leaf, after which additional mechanically acting coupling elements between the shaft and the pivot axis can be dispensed with.

Eine Weiterbildung des Türsystems ist als Falttürsystem ausgebildet. Ein solches als Falttürsystem ausgebildetes Türsystem hat den Vorteil, dass das Türsystem einen geringen Platzbedarf in einer senkrecht zur Türschliessebene ausgerichteten Richtung aufweist.A further development of the door system is designed as a folding door system. Such a door system designed as a folding door system has the advantage that the door system requires little space in a direction perpendicular to the door closing plane.

Bei einer Weiterbildung des Türsystems sind die Welle und/oder die mindestens eine Schwenkachse im Wesentlichen vertikal entlang des Aufzugsschachtes bzw. vertikal im Aufzugsschacht anordenbar. Die vertikale Anordnung der Welle bzw. der mindestens eine Schwenkachse im Aufzugsschacht hat den Vorteil, dass eine platzsparende Anordnung der Antriebseinheit bzw. der Schwenkachse ermöglicht ist, da sie auf einfache Weise im Türpfosten bzw. unmittelbarer Umgebung des Türpfostens verstaut werden kann.In a further development of the door system, the shaft and/or the at least one pivot axis can be arranged essentially vertically along the elevator shaft or vertically in the elevator shaft. The vertical arrangement of the shaft or the at least one pivot axis in the elevator shaft has the advantage that a space-saving arrangement of the drive unit or pivot axis is made possible, since it can easily be stowed in the doorpost or in the immediate vicinity of the doorpost.

Bei einer Weiterbildung des Türsystems sind eine Abtriebswelle eines Motors der Antriebseinheit und die angetriebene, schwenkbar gelagerte Welle koaxial zueinander angeordnet. Eine solche koaxiale Anordnung hat den Vorteil, dass die Anzahl mechanischer Komponenten des Türsystems weitgehend verringert werden kann. Beispielhaft ist kein Getriebe oder Ähnliches zwischen einer solchen Abtriebswelle und der schwenkbar gelagerten Welle vonnöten.In a further development of the door system, an output shaft of a motor of the drive unit and the driven, pivotably mounted shaft are arranged coaxially with one another. Such a coaxial arrangement has the advantage that the number of mechanical components of the door system can be largely reduced. For example, no gear or the like is required between such an output shaft and the pivoted shaft.

Figur 1 zeigt eine Aufzugsanlage 2. Die Aufzugsanlage 2 ist in einem Aufzugsschacht 1 angeordnet. Der Aufzugsschacht 1 weist mehrere an Stockwerken angeordnete Schachttüröffnungen auf. Die Aufzugsanlage 2 umfasst mehrere Schachttüren 6.1, 6.2, 6.3, wobei eine erste der Schachttüren 6.1 an einer ersten der Schachttüröffnungen und eine zweite der Schachttüren 6.2 an einer zweiten der Schachttüröffnungen angeordnet ist. Die Aufzugsanlage 2 weist eine Aufzugskabine 4 mit einer Kabinentür 7 auf. figure 1 shows an elevator system 2. The elevator system 2 is arranged in an elevator shaft 1. FIG. The elevator shaft 1 has a plurality of shaft door openings arranged at floors. The elevator installation 2 comprises a plurality of shaft doors 6.1, 6.2, 6.3, a first of the shaft doors 6.1 being arranged at a first of the shaft door openings and a second of the shaft doors 6.2 being arranged at a second of the shaft door openings. The elevator system 2 has an elevator car 4 with a car door 7 .

Die Aufzugskabine 4 ist verfahrbar innerhalb des Aufzugsschachtes 1 angeordnet. Um ausreichend Sicherheit während der Fahrt der Aufzugskabine 4 zu gewährleisten, ist die Aufzugskabine 4 ausreichend von den im Aufzugsschacht 1 fixierten Komponenten, insbesondere, den Schachttüren 6.1, 6.2, 6.3 beabstandet. Dieser Abstand ist durch einen in Figur 1 gezeigten Türschwellenspalt S gekennzeichnet. Mittels des Türschwellenspalts S wird verhindert, dass die Komponenten der Aufzugskabine 4, beispielsweise die Kabinentür 7, die im Aufzugsschacht 1 fixierten Komponenten während des Verfahrens der Aufzugskabine 4 touchieren bzw. gegen diese prallen.The elevator car 4 is arranged to be movable within the elevator shaft 1 . In order to ensure sufficient safety while the elevator car 4 is traveling, the elevator car 4 is sufficiently spaced from the components fixed in the elevator shaft 1, in particular the shaft doors 6.1, 6.2, 6.3. This distance is divided by an in figure 1 shown door sill gap S marked. The door sill gap S prevents the components of the elevator car 4, for example the car door 7, from touching or colliding with the components fixed in the elevator shaft 1 during the movement of the elevator car 4.

Die Figuren 2 bis 5 zeigen ein Türsystem für eine in Figur 1 dargestellte Aufzugsanlage 2. Beispielhaft ist das Türsystem im horizontalen Querschnitt dargestellt. Das Türsystem kann aus einer Kabinentür 7 und einer Schachtür 6 gebildet sein, wobei die Kabinentür 7 auf einer Kabinentürseite und die Schachtür 6 auf einer Schachttürseite anordenbar sind. Die Kabinentür 7 kann ein erstes Türblatt 14 und die Schachttür 6 kann ein der Schachttür zuordenbares weiteres Türblatt 12 umfassen. Die Kabinentür 7 und die Schachtür 6 sind bei einer gemäss Figur 2 gezeigten Geschlossenstellung des Türsystems beispielhaft mittels des Türschwellenspaltes S voneinander beabstandet. Während einer zumindest teilweisen Offenstellung des Türsystems, wie in den Figuren 3, 3.5 und 4 gezeigt, ragt mindestens ein Bestandteil der Kabinentür 7 und/oder Schachttür 6 in den Türschwellenspalt S hinein.The Figures 2 to 5 show a door system for an in figure 1 Elevator installation 2 shown. The door system is shown in horizontal cross-section as an example. The door system can be formed from a car door 7 and a shaft door 6, with the car door 7 being able to be arranged on a car door side and the shaft door 6 being able to be arranged on a shaft door side. The car door 7 can comprise a first door panel 14 and the shaft door 6 can comprise a further door panel 12 which can be assigned to the shaft door. The car door 7 and the shaft door 6 are in accordance with figure 2 shown closed position of the door system, for example, by means of the door sill gap S spaced apart. During an at least partially open position of the door system, as in the Figures 3 , 3.5 and 4 shown, at least one component of the car door 7 and/or shaft door 6 protrudes into the door sill gap S.

Das Türsystem umfasst eine Antriebseinheit. Die Antriebseinheit ist Bestandteil der Kabinentür 7. Die Antriebseinheit umfasst einen nicht dargestellten Motor und eine schwenkbar gelagerte Welle 20. Mittels dieses Motors ist die Welle 20 antreibbar, also schwenkbar.The door system includes a drive unit. The drive unit is part of the cabin door 7. The drive unit comprises a motor (not shown) and a pivoted shaft 20. The shaft 20 can be driven, ie pivoted, by means of this motor.

Das Türsystem umfasst darüber hinaus eine antriebsseitig Primärschwenkeinheit und/oder eine Sekundärschwenkeinheit, wobei die Sekundärschwenkeinheit nicht antriebsseitig angeordnet ist. Das heisst, dass die Primärschwenkeinheit und die Antriebseinheit Bestandteil einer ersten der die Schachttür 6 und die Kabinentür 7 umfassenden Türen sind und die Sekundärschwenkeinheit Bestandteil der zweiten der die Schachttür 6 und die Kabinentür 7 umfassenden Türen ist. Gemäss dem vorliegenden Ausführungsbeispiel ist die Primärschwenkeinheit Bestandteil der Kabinentür 7 und die Sekundärschwenkeinheit Bestandteil der Schachttür 6.The door system also includes a primary pivot unit on the drive side and/or a secondary pivot unit, the secondary pivot unit not being arranged on the drive side. This means that the primary swivel unit and the drive unit are part of a first door comprising the shaft door 6 and the car door 7 and the secondary swivel unit is part of the second door comprising the shaft door 6 and the car door 7 . According to the present exemplary embodiment, the primary pivoting unit is part of the car door 7 and the secondary pivoting unit is part of the shaft door 6.

Die Primärschwenkeinheit umfasst eine erste Schwenkachse 24 und die an dieser ersten Schwenkachse 24 befestigten Komponenten. Die Sekundärschwenkeinheit umfasst eine weitere Schwenkachse 22 und die an dieser weiteren Schwenkachse 22 befestigten Komponenten. Die Schwenkachse 24 der Kabinentür 7 ist mit einem Kabinentürblatt 14 bzw. die Schwenkachse 22 der Schachttür 6 ist mit einem Schachttürblatt 12 koppelbar. Zudem können die Schwenkachsen 22, 24 die Schwenkachsen des jeweiligen Schacht- bzw. Kabinentürblattes 12, 14 sein. Innerhalb der Figurenbeschreibung sind die Schwenkachse 24 der hier kabinentürseitigen Primärschwenkeinheit als erste Schwenkachse 24 und die Schwenkachse 22 der hier schachttürseitigen Sekundärschwenkeinheit als zweite Schwenkachse 22 bezeichnet. Die folgenden an der Welle 20 oder der ersten Schwenkachse 24 oder der zweiten Schwenkachse 22 fixierten Elemente sind entweder Bestandteil der Kabinen- oder der Schachttür 6, 7.The primary pivot unit includes a first pivot axis 24 and the components attached to this first pivot axis 24 . The secondary pivot unit comprises a further pivot axis 22 and the components attached to this further pivot axis 22 . The pivot axis 24 of the car door 7 can be coupled to a car door panel 14 and the pivot axis 22 of the shaft door 6 to a shaft door panel 12 . In addition, the pivot axes 22, 24 can be the pivot axes of the respective shaft or car door panel 12, 14. Within the figure description are the pivot axis 24 the primary pivoting unit on the car door side is referred to as the first pivoting axis 24 and the pivoting axis 22 of the secondary pivoting unit on the shaft door side is referred to as the second pivoting axis 22 . The following elements fixed to the shaft 20 or the first pivot axis 24 or the second pivot axis 22 are either part of the car door or the landing door 6, 7.

An der Welle 20 der Antriebseinheit ist ein erstes Sperrelement 40 fixiert. An der ersten Schwenkachse 24 ist eine mit dem ersten Sperrelement 40 zusammenwirkende Sperrausnehmung 42 fixiert. Das erste Sperrelement 40 wirkt dabei derart auf die an der Welle 20 fixierte erste Sperrausnehmung 42, dass die erste Schwenkachse 24 in einer ersten Endposition, das heisst, dass das der ersten Schwenkachse 24 zugeordnete Kabinentürblatt 14 in einer Geschlossenstellung, blockierbar ist. Das erste Sperrelement 40 und die erste Sperrausnehmung 42 bilden dabei vorzugsweise einen Formschluss.A first blocking element 40 is fixed to the shaft 20 of the drive unit. A locking recess 42 cooperating with the first locking element 40 is fixed on the first pivot axis 24 . The first blocking element 40 acts on the first blocking recess 42 fixed to the shaft 20 in such a way that the first pivot axis 24 can be blocked in a first end position, i.e. that the cabin door panel 14 assigned to the first pivot axis 24 can be blocked in a closed position. The first locking element 40 and the first locking recess 42 preferably form a form fit.

An der Welle 20 kann ein erstes Mitnahmemittel 28 fixiert sein. Im Falle eines an der Welle 20 fixierten ersten Mitnahmemittels 28 kann an der ersten Schwenkachse 24 ein durch das erste Mitnahmemittel 28 betätigbares Gegenelement 29 fixiert sein. Bei einer Betätigung des Gegenelementes 29 durch das erste Mitnahmemittel 28 bewirkt eine Schwenkbewegung der Welle 20 eine Schwenkbewegung der ersten Schwenkachse 24.A first entrainment means 28 can be fixed to the shaft 20 . In the case of a first entrainment means 28 fixed to the shaft 20 , a counter-element 29 that can be actuated by the first entrainment means 28 can be fixed to the first pivot axis 24 . When the counter-element 29 is actuated by the first carrier means 28, a pivoting movement of the shaft 20 causes a pivoting movement of the first pivot axis 24.

An der ersten zur Primärschwenkeinheit gehörigen Schwenkachse 24 kann zusätzlich zur Sperrausnehmung 42 eine zweite Sperrausnehmung 44 fixiert sein. Das erste Sperrelement 40 wirkt auf die zweite an der ersten Schwenkachse 24 fixierte Sperrausnehmung 44 derart, dass die erste Schwenkachse 24 in einer zweiten einer Offenstellung des Türsystems entsprechenden Endposition, das heisst, dass das der ersten Schwenkachse 24 zugeordnete Türblatt 14 in einer Offenstellung, blockierbar ist. Das erste Sperrelement 40 und die zweite Sperrausnehmung 42 können in dieser zweiten Endposition der ersten Schwenkachse 24 einen Formschluss bilden. Im Falle einer solchen Fixierung sowohl der ersten und zweiten Sperrausnehmungen 42, 44 als auch des vorzugsweise als Eingriff ausgebildeten Gegenelementes 29 an der ersten Schwenkachse 24 und darüber hinaus der Fixierung sowohl des ersten Sperrelementes 40 als auch des ersten Mitnahmemittels 28 an der Welle 20 der Antriebseinheit ist das Zusammenwirken der Antriebseinheit mit der Primärschwenkeinheit ähnlich dem eines Malteserkreuzgesperres.In addition to the locking recess 42, a second locking recess 44 can be fixed on the first swivel axis 24 belonging to the primary swivel unit. The first blocking element 40 acts on the second blocking recess 44 fixed on the first pivot axis 24 in such a way that the first pivot axis 24 can be blocked in a second end position corresponding to an open position of the door system, i.e. the door leaf 14 assigned to the first pivot axis 24 in an open position is. The first locking element 40 and the second locking recess 42 can form a form fit in this second end position of the first pivot axis 24 . In the case of such a fixation of both the first and second blocking recesses 42, 44 and the counter-element 29, which is preferably designed as an engagement, on the first pivot axis 24 and, moreover, the fixation of both the first blocking element 40 and the first entrainment means 28 on the shaft 20 of the drive unit the interaction of the drive unit with the primary swivel unit is similar to that of a Maltese cross ratchet.

Das erste Sperrelement 40 und die an der ersten Schwenkachse 24 fixierte(n) Sperrausnehmung(en) 42, 44 sind derart ausgebildet, dass bei einer durch das erste Mitnahmemittel 28 bewirkten Schwenkbewegung der ersten Schwenkachse 24 das an der Welle 20 fixierte Sperrelement 40 keine blockierende Wirkung auf die erste Schwenkachse 24 ausgeübt wird. Demnach ist eine Schwenkbewegung der ersten Schwenkachse 24 und eine Öffnungs- bzw. Schliessbewegung des der ersten Schwenkachse 24 zugeordneten Türblattes 14 ermöglicht.The first blocking element 40 and the blocking recess(es) 42, 44 fixed to the first pivot axis 24 are designed in such a way that when the first entrainment means 28 causes a pivoting movement of the first pivot axis 24, the blocking element 40 fixed to the shaft 20 does not block Effect on the first pivot axis 24 is exerted. Accordingly, a pivoting movement of the first pivot axis 24 and an opening or closing movement of the door leaf 14 assigned to the first pivot axis 24 is made possible.

Das Türsystem kann eine Getriebeeinheit 60 zur Verriegelung des nicht antriebsseitigen Türblattes 12, hier der Schachttür 6, in seiner Geschlossenstellung umfassen. Die Getriebeeinheit 60 ist daher Bestandteil der Schachttür 6. Die Getriebeeinheit 60 kann zwei Schwenkachsen 50, 51, ein weiteres Sperrelement 70 und ein weiteres Gegenelement 29.1 umfassen, wobei die Schwenkachsen 50, 51 der Getriebeeinheit 60 beispielhaft mittels eines Zahnradgetriebes gekoppelt sein können. Das Sperrelement 70 der Getriebeeinheit 60 ist an einer ersten Schwenkachse 50 der Getriebeeinheit 60 fixiert. An der zweiten Schwenkachse 22 ist eine weitere Sperrausnehmung 72 fixiert, die durch das Sperrelement 70 der Getriebeeinheit 60 betätigbar ist.The door system can include a gear unit 60 for locking the non-drive-side door panel 12, here the shaft door 6, in its closed position. The gear unit 60 is therefore part of the shaft door 6. The gear unit 60 can comprise two pivot axes 50, 51, a further blocking element 70 and a further counter-element 29.1, with the pivot axes 50, 51 of the gear unit 60 being able to be coupled by means of a toothed gear, for example. The locking element 70 of the gear unit 60 is fixed to a first pivot axis 50 of the gear unit 60 . A further blocking recess 72 is fixed to the second pivot axis 22 and can be actuated by the blocking element 70 of the transmission unit 60 .

Das Sperrelement 70 der Getriebeeinheit 60 und die an der zweiten Schwenkachse 22 fixierte Sperrausnehmung 72 sind derart ausgebildet, dass die Blockierung der zweiten Schwenkachse 22 in einer der Geschlossenstellung des Türsystems entsprechenden Endposition bzw. unmittelbar vor einer Schwenkbewegung der zweiten Schwenkachse 22 deren Deblockierung initiierbar ist.The blocking element 70 of the transmission unit 60 and the blocking recess 72 fixed to the second pivot axis 22 are designed in such a way that the blocking of the second pivot axis 22 can be initiated in an end position corresponding to the closed position of the door system or immediately before a pivot movement of the second pivot axis 22 and its unblocking can be initiated.

Das Gegenelement 29.1 der Getriebeeinheit 60 ist an der zweiten zur Getriebeeinheit 60 gehörigen Schwenkachse 51 fixiert, so dass das Gegenelement 29.1 der Getriebeeinheit 60 durch das erste Mitnahmemittel 28 derart betätigbar ist, dass die erste Schwenkachse 50 der Getriebeeinheit 60 mittels der beispielhaft als Zahnradgetriebe vorgesehenen Kopplung der zwei Schwenkachsen 50, 51 verschwenkt werden kann. Folglich ist durch die Getriebeeinheit 60 das an die Sekundärschwenkeinheit gekoppelte Türblatt 12 ver- bzw. entriegelbar.The counter-element 29.1 of the gear unit 60 is fixed to the second pivot axis 51 belonging to the gear unit 60, so that the counter-element 29.1 of the gear unit 60 can be actuated by the first entrainment means 28 in such a way that the first pivot axis 50 of the gear unit 60 by means of the coupling provided, for example, as a gear mechanism the two pivot axes 50, 51 can be pivoted. Consequently, the door leaf 12 coupled to the secondary pivoting unit can be locked or unlocked by the gear unit 60 .

Das an der Welle 20 fixierte Sperrelement 40 kann in einer der Offenstellung des Türsystems entsprechenden Endposition derart auf die an der zweiten Schwenkachse 22 fixierte Sperrausnehmung 72 wirken, dass das an die zweite Schwenkachse 22 koppelbare Türblatt in seiner Offenstellung blockiert werden kann.In an end position corresponding to the open position of the door system, the blocking element 40 fixed to the shaft 20 can move to the end position fixed to the second pivot axis 22 Blocking recess 72 act so that the door leaf which can be coupled to the second pivot axis 22 can be blocked in its open position.

An der Welle 20 kann ein zweites Mitnahmemittel 26 fixiert sein. Das zweite Mitnahmemittel 26 ist zum Erzeugen einer Schwenkbewegung der zweiten Schwenkachse 22 geeignet. Eine solche Schwenkbewegung der zweiten Schwenkachse 22 kann ausschliesslich erfolgen, wenn die Blockierung der zweiten Schwenkachse 22 vorzugsweise mittels der Getriebeeinheit 60 aufgehoben ist. Das zweite Mitnahmemittel 26 betätigt dabei ein an der zweiten Schwenkachse 22 zu fixierendes weiteres Gegenelement 27 derart, dass das zweite Mitnahmemittel 26 bei der Schwenkbewegung der Welle 20 in das an der zweiten Schwenkachse 22 fixierte Gegenelement 27 eingreift und die zweite Schwenkachse 22 zwischen ihren beiden Endpositionen verschwenkt werden kann. Das bedeutet, dass das mit der zweiten Schwenkachse 22 koppelbare Türblatt durch eine Schwenkbewegung A der Welle 20 in eine Offen- bzw. Geschlossenstellung geschwenkt wird.A second entraining means 26 can be fixed to the shaft 20 . The second entraining means 26 is suitable for generating a pivoting movement of the second pivot axis 22 . Such a pivoting movement of the second pivot axis 22 can only take place when the blocking of the second pivot axis 22 is removed, preferably by means of the gear unit 60 . The second entrainment means 26 actuates a further counter-element 27 to be fixed on the second pivot axis 22 in such a way that the second entrainment means 26 engages in the counter-element 27 fixed on the second pivot axis 22 during the pivoting movement of the shaft 20 and the second pivot axis 22 between its two end positions can be pivoted. This means that the door leaf that can be coupled to the second pivot axis 22 is pivoted into an open or closed position by a pivoting movement A of the shaft 20 .

Alternativ zu der in den Figuren 2 bis 5 gezeigten Ausführungsform können die erwähnten Komponenten auf der jeweilig anderen Seite der die Kabinentür- und die Schachttürseite umfassenden Seiten angeordnet sein. Das heisst, dass in diesem alternativen Fall die gemäss den Figuren 2 bis 4 dargestellten der Schachttür 6 zugehörigen Komponenten Bestandteil der Kabinentür und gleichermassen die gemäss den Figuren 2 bis 4 dargestellten der Kabinentür 7 zugehörigen Komponenten Bestandteil der Schachttür sind.As an alternative to the one in the Figures 2 to 5 In the embodiment shown, the components mentioned can be arranged on the respective other side of the sides comprising the car door side and the shaft door side. This means that in this alternative case according to the Figures 2 to 4 shown the shaft door 6 associated components part of the car door and equally according to Figures 2 to 4 illustrated components associated with the car door 7 are part of the shaft door.

Figur 2 zeigt das Türsystem in seiner Offenstellung. Die kabinentürseitigen Elemente umfassend die die Welle 20 aufweisende Antriebseinheit sind durch den Türschwellenspalt S von den schachtürseitig angeordneten Elementen des Türsystems getrennt. In der Geschlossenstellung des Türsystems ragen demnach weder Komponenten der Kabinentür 7 noch Komponenten der Schachtür 6 in diesen Türschwellenspalt S hinein. figure 2 shows the door system in its open position. The car door-side elements including the drive unit having the shaft 20 are separated by the door sill gap S from the shaft door-side elements of the door system. In the closed position of the door system, neither components of the car door 7 nor components of the shaft door 6 protrude into this door sill gap S.

Das an der Welle 20 fixierte Sperrelement 40 wirkt auf die an der ersten Schwenkachse 24 fixierte erste Sperrausnehmung 42 derart, dass das antriebsseitig angeordnete mit der ersten Schwenkachse 24 gekoppelte Türblatt 14 in seiner Geschlossenstellung blockiert ist. Das auf der Schachtürseite angeordnete Sperrelement 70 der Getriebeeinheit 60 wirkt derart auf die an der zweiten Schwenkachse 22 fixierte Sperrausnehmung 72, dass das mit der zweiten Schwenkachse 22 gekoppelte Türblatt 12 ebenfalls in seiner Geschlossenstellung blockiert ist. Derart können Schwenkbewegungen B der ersten und der zweiten Schwenkachse 22, 24, wie sie beispielhaft durch Personen verursachte Krafteinwirkungen auf das Türblatt 12, 14 der Kabinen- bzw. Schachttür 6, 7 bewirkt werden können, verhindert werden.The blocking element 40 fixed to the shaft 20 acts on the first blocking recess 42 fixed to the first pivot axis 24 in such a way that the door leaf 14 arranged on the drive side and coupled to the first pivot axis 24 is blocked in its closed position. The locking element 70 of the gear unit 60 arranged on the shaft door side acts on the locking recess 72 fixed to the second pivot axis 22 in such a way that the door leaf 12 coupled to the second pivot axis 22 is also in its closed position is blocked. In this way, pivoting movements B of the first and second pivot axes 22, 24, such as those caused by people acting on the door leaf 12, 14 of the car or shaft door 6, 7, can be prevented.

Die Figuren 3 und 4 zeigen das in Figur 2 dargestellte Türsystem in verschiedenen Phasen einer durch die Antriebseinheit bewirkten Öffnung bzw. Schliessung. In der Beschreibung zu den Figuren 3 und 3.5 wird der Ablauf einer Öffnung des Türsystems beschrieben, wie dies durch die mittels der Bezugszeichen A und B gezeichnete Richtung der Schwenkbewegungen der Welle 20 bzw. der ersten und der zweiten Schwenkachse 22, 24 dargestellt ist. Selbstverständlich kann mittels eines umgekehrten Ablaufes ebenso die Schliessung des Türsystems beschrieben werden.The Figures 3 and 4 show that in figure 2 door system shown in different phases of an opening or closing effected by the drive unit. In the description of the Figures 3 and 3.5, the process of opening the door system is described, as illustrated by the direction of the pivoting movements of the shaft 20 or the first and second pivot axes 22, 24 indicated by the reference symbols A and B. Of course, the closing of the door system can also be described by means of a reverse process.

Figur 3 zeigt das Türsystem während einer ersten Phase seiner Öffnung, einer Entriegelung des Türsystems. Bei einer durch den Motor der Antriebseinheit bewirkten Schwenkbewegung Ader Welle 20 wird das erste an der Welle 20 fixierte Mitnahmemittel 28 in den Türschwellenspalt S eingeschwenkt. Bei fortgeführter Schwenkbewegung A der Welle 20 betätigt das erste Mitnahmemittel 28 das Gegenelement 29.1 der Getriebeeinheit 60. Das bewirkt, dass die gekoppelten Schwenkachsen 50, 51 der Getriebeeinheit 60 eine Schwenkbewegung C1 bzw. eine Schwenkbewegung C2 ausführen. Das an der ersten Schwenkachse 50 der Getriebeeinheit 60 fixierte Sperrelement 70 der Getriebeeinheit 60 schwenkt demnach derart aus einem Eingriff mit der Sperrausnehmung 72 aus, dass die zweite Schwenkachse 22 deblockiert, also entriegelt wird. figure 3 shows the door system during a first phase of its opening, an unlocking of the door system. When the motor of the drive unit causes a pivoting movement of the shaft 20, the first entraining means 28 fixed to the shaft 20 is pivoted into the gap S in the door sill. With continued pivoting movement A of the shaft 20, the first driving means 28 actuates the counter-element 29.1 of the gear unit 60. This causes the coupled pivot axes 50, 51 of the gear unit 60 to execute a pivoting movement C1 or a pivoting movement C2. The locking element 70 of the gear unit 60 fixed to the first pivot axis 50 of the gear unit 60 accordingly pivots out of engagement with the locking recess 72 in such a way that the second pivot axis 22 is unblocked, ie unlocked.

Nach einem vollständig vollzogenen Ausschwenken des Sperrelementes 70 der Getriebeeinheit 60 aus der an zweiten Schwenkachse 22 fixierten Sperrausnehmung 72 ist die zweite Schwenkachse 22 entriegelt. Das bedeutet, dass das nicht antriebsseitig anordenbare Türblatt, welches dieser zweiten Schwenkachse 22 zugeordnet ist, hier der Schachttür 6, entriegelt ist.After the locking element 70 of the gear unit 60 has been completely pivoted out of the locking recess 72 fixed to the second pivot axis 22, the second pivot axis 22 is unlocked. This means that the door panel which cannot be arranged on the drive side and which is assigned to this second pivot axis 22, in this case the shaft door 6, is unlocked.

Das an der Welle 20 fixierte Sperrelement 40 und die an der ersten Schwenkachse 24 fixierte Sperrausnehmung 42 können derart ausgebildet sein, dass eine Entriegelung, also Deblockierung der ersten Schwenkachse 24 und eine Entriegelung der zweiten Schwenkachse 22 zu verschiedenen Zeitpunkten erfolgt, wobei sowohl die erste als auch die zweite Schwenkachse 22, 24 im Laufe der Schwenkbewegung A der Welle 20 entriegelt werden.The blocking element 40 fixed to the shaft 20 and the blocking recess 42 fixed to the first pivot axis 24 can be designed in such a way that unlocking, i.e. unblocking, of the first pivot axis 24 and unlocking of the second pivot axis 22 takes place at different points in time, with both the first and also the second Pivot axis 22, 24 are unlocked in the course of pivoting movement A of the shaft 20.

Figur 4 zeigt das Türsystem während einer zweiten Phase seiner Öffnung, wobei die zweite Phase seiner Öffnung zeitlich der ersten gemäss Figur 3 dargestellten Phase seiner Öffnung nachgeordnet ist. Die zweite Phase der Öffnung beschreibt die Verschwenkung der Schwenkachse(n) 22, 24 und damit gegebenenfalls die Verschwenkung des/der mit dieser/diesen Schwenkachse(n) 22, 24 gekoppelten Türblattes bzw. Türblätter, also das Freigeben der Türöffnung. figure 4 shows the door system during a second phase of its opening, the second phase of its opening being timed according to the first figure 3 shown phase is subordinate to its opening. The second phase of the opening describes the pivoting of the pivot axis(s) 22, 24 and thus possibly the pivoting of the door leaf or door leaves coupled to this/these pivot axis(s) 22, 24, i.e. the release of the door opening.

Bei der fortgesetzten durch den Motor der Antriebseinheit bewirkten Schwenkbewegung A der Welle 20 betätigt das erste an der Welle 20 fixierte Mitnahmemittel 28 das an der ersten Schwenkachse 24 fixierte Gegenelement 29 und bewirkt somit die Schwenkbewegung B der entriegelten ersten Schwenkachse 24. Das an der Welle 20 fixierte zweite Mitnahmemittel 26 betätigt das an der zweiten Schwenkachse 22 fixierte weitere Gegenelement 27 und bewirkt somit die Schwenkbewegung B der entriegelten zweiten Schwenkachse 22. Das erste und das zweite Mitnahmemittel 26, 28 und die an der ersten bzw. zweiten Schwenkachse 22, 24 fixierten Gegenelemente 27, 29 können derart ausgestaltet sein, dass die Schwenkbewegungen der ersten und der zweiten Schwenkachse 22, 24 zeitgleich oder zeitlich versetzt erfolgen.With the continued pivoting movement A of the shaft 20 caused by the motor of the drive unit, the first carrier means 28 fixed to the shaft 20 actuates the counter-element 29 fixed to the first pivot axis 24 and thus causes the pivoting movement B of the unlocked first pivot axis 24. The on the shaft 20 The second entrainment means 26 that is fixed in place actuates the other counter-element 27 that is fixed on the second pivot axis 22 and thus causes the pivoting movement B of the unlocked second pivot axis 22. The first and the second entrainment means 26, 28 and the counter-elements that are fixed on the first and second pivot axis 22, 24 27, 29 can be designed in such a way that the pivoting movements of the first and the second pivot axis 22, 24 take place at the same time or at different times.

In einer letzten nicht dargestellten Phase der Öffnung des Türsystems sind die Schwenkbewegungen B der ersten und der zweiten Schwenkachse 22, 24 abgeschlossen. Die demnach erreichte Stellung dieser Schwenkachsen 22, 24 entspricht ihrer in Figur 5 gezeigten Stellung. Die Schwenkbewegung A der Welle 20 kann weiter fortgesetzt werden, um gegebenenfalls eine Blockierung der Schwenkachsen 22, 24 zu erwirken.In a final phase of the opening of the door system, not shown, the pivoting movements B of the first and second pivot axes 22, 24 are completed. The position reached by these pivot axes 22, 24 corresponds to their in figure 5 shown position. The pivoting movement A of the shaft 20 can be continued in order to block the pivot axes 22, 24 if necessary.

Durch diese Fortsetzung der Schwenkbewegung A der Welle 20 kann das an der Welle 20 fixierte Sperrelement 40 derart in die zweite an der ersten Schwenkachse 24 fixierte Sperrausnehmung 44 eingeschwenkt werden, dass die gemäss Figur 5 gezeigte Blockierung der ersten Schwenkachse 24 resultiert. Vorzugsweise bilden das Sperrelement 40 und die Sperrausnehmung 40 in der der Offenstellung des Türsystems entsprechenden Stellung der ersten Schwenkachse 24 einen Formschluss.By this continuation of the pivoting movement A of the shaft 20, the locking element 40 fixed to the shaft 20 can be pivoted into the second locking recess 44 fixed to the first pivot axis 24 in such a way that according to figure 5 shown blocking of the first pivot axis 24 results. The blocking element 40 and the blocking recess 40 preferably form a form fit in the position of the first pivot axis 24 corresponding to the open position of the door system.

Figur 5 zeigt dass in den Figuren 2 bis 4 gezeigte Türsystem in seiner Offenstellung. Sowohl die erste Schwenkachse 24, hier der Kabinentür 7, als auch die zweite Schwenkachse 22, hier der Schachttür 6, sind in ihrer der Offenstellung des Türsystem entsprechenden Endposition mittels des an der Welle fixierten Sperrelementes 40 blockiert. figure 5 shows that in the Figures 2 to 4 shown door system in its open position. Both the first pivot axis 24, here the car door 7, and the second pivot axis 22, here the shaft door 6, are blocked in their end position corresponding to the open position of the door system by means of the blocking element 40 fixed to the shaft.

Figur 6 zeigt das in den Figuren 2 bis 5 dargestellte Türsystem in einem vertikalen Schnitt in einer gemäss Figur 2 gezeigten Offenstellung und enthält daher dieselben Bezugszeichen wie Figur 2 mit Ausnahme der Kennzeichnung der Türblätter und der Schwenkbewegungen. figure 6 shows that in the Figures 2 to 5 shown door system in a vertical section in accordance with figure 2 shown open position and therefore contains the same reference numerals as figure 2 with the exception of the labeling of the door leaves and the pivoting movements.

Die Antriebseinheit 30 umfasst die Welle 20, eine Antriebswelle 32 und einen Motor 34. Die Antriebswelle 32 kann koaxial zur Welle 20 angeordnet sein. Die erste Schwenkachse 24 und die zweite Schwenkachse 22 und die Welle des Motors 20 können parallel zueinander angeordnet sein bzw. vertikal im Aufzugsschacht anordenbar sein.The drive unit 30 comprises the shaft 20, a drive shaft 32 and a motor 34. The drive shaft 32 can be arranged coaxially with the shaft 20. The first pivot axis 24 and the second pivot axis 22 and the shaft of the motor 20 can be arranged parallel to one another or can be arranged vertically in the elevator shaft.

Vorzugsweise sind das erste Mitnahmemittel 28 und diejenigen Komponenten des Türsystems, welche durch das erste Mitnahmemittel 28 betätigbar sind, in einer ersten Ebene 110 angeordnet. Demgemäss sind das zweite Mitnahmemittel 26 und diejenigen Komponenten des Türsystems, welche durch das zweite Mitnahmemittel 26 betätigbar sind, in einer zweiten Ebene 120 angeordnet. Das heisst, dass das an der ersten Schwenkachse 24 fixierte Gegenelement 29 und das Gegenelement 29.1 der Getriebeeinheit 60 in der ersten Ebene 110 angeordnet sind und dass das an der zweiten Schwenkachse 22 fixierte Gegenelement 27 in der zweiten Ebene 120 angeordnet ist. Vorzugsweise sind die an der ersten Schwenkachse 24 fixierte(n) Sperrausnehmung(en) 42, 44 ebenso in der ersten Ebene 110 angeordnet und die an der zweiten Schwenkachse 22 fixierte Sperrausnehmung 72, sowie das Sperrelement 70 der Getriebeeinheit 60 in der zweiten Ebene 120 angeordnet.The first entrainment means 28 and those components of the door system which can be actuated by the first entrainment means 28 are preferably arranged in a first plane 110 . Accordingly, the second entrainment means 26 and those components of the door system which can be actuated by the second entrainment means 26 are arranged in a second plane 120 . This means that the counter-element 29 fixed to the first pivot axis 24 and the counter-element 29.1 of the transmission unit 60 are arranged in the first plane 110 and that the counter-element 27 fixed to the second pivot axis 22 is arranged in the second plane 120. The locking recess(es) 42, 44 fixed to the first pivot axis 24 are preferably also arranged in the first plane 110 and the locking recess 72 fixed to the second pivot axis 22, as well as the locking element 70 of the transmission unit 60, are arranged in the second plane 120 .

Vorzugsweise kann das an der Welle 20 fixierte Sperrelement bei einer solchen Anordnung dieser genannten Komponenten in der ersten bzw. zweiten Ebene 110, 120 zwei Bereiche 40', 40" umfassen. Ein erster der Bereiche 40' des an der Welle 20 fixierten Sperrelementes ist in der ersten Ebene 110 angeordnet und kann demnach auf beschriebene Weise auf die an der ersten Schwenkachse 24 fixierte(n) Sperrausnehmung(en) 42, 44 wirken.
