Definitions
- the invention relates to a device for unlocking a shaft door, an elevator installation with such a device and a method for unlocking such a shaft door.
- An elevator installation usually comprises an elevator car that can be moved within an elevator shaft.
- an elevator car that can be moved within an elevator shaft.
- components of the elevator system for example the lower area of the elevator car or components arranged in the shaft pit of the elevator shaft, to maintenance, a service technician enters the shaft pit through a bottom shaft door
- JP H11 171441 A discloses prior art devices and methods.
- the service technician unlocks the bottom shaft door in order to open this shaft door and thus to be able to leave the elevator shaft.
- the corresponding locking device of the shaft door is usually located in the upper door area of this shaft door. It is known that an unlocking cable can be fixed to the bolt of the locking device for unlocking from the inside of the elevator shaft, this unlocking cable extending from the locking device into the lower door area of the elevator door. The service technician can pull this release rope to unlock the elevator door.
- each elevator door has an energy store for automatic closing of the elevator door in the event of a power failure.
- the disadvantage of such an embodiment of the elevator door is that the presence of the energy storage device and the unlocking device represent a component-rich, that is to say complicated, construction of the device.
- an elevator system which comprises several shaft doors arranged one above the other, through which shaft doors the elevator shaft of the elevator system can be accessed from several floors arranged one above the other, the device being arranged on a lowermost of the shaft doors.
- the object is also achieved by a method for unlocking an elevator door with such a device, the door leaf being unlocked by moving the energy store.
- the invention is based on the knowledge that an energy store is usually arranged in the lower area of the elevator door and is thus easily accessible to a service technician located in the shaft pit if this elevator door is arranged directly on the shaft pit.
- this energy store is coupled to an upper area of the elevator door or the door leaf, in which upper area the bolt for locking the elevator door is also arranged is.
- the elastic element With the help of the elastic element, it is consequently possible, when the door leaf is in the closed position, to generate a movement in the upper area of the door leaf which acts on the bolt when the energy storage mechanism is preferably shifted manually. This movement carried out in the lower door area is used to transfer the bolt from its locked position to its unlocked position by means of the elastic element in the upper door area and thus to release the door leaf for opening.
- Elastic elements within the meaning of this description also include devices that experience a change in length by moving the energy store for the purpose of unlocking, this change in length being reversed when the energy store returns to its starting position corresponding to the locked position of the bolt.
- the energy store is coupled to the door leaf by means of a fastening point arranged on the door leaf. In this way it can be ensured that the movement of the energy store causes the door leaf to close when the door leaf is open.
- the elastic element is supported at the fastening point and can be relaxed by displacing the energy store, which moves the bolt into its locked position. In this way it can be achieved that the movement of the energy store in the lower area of the elevator door causes a movement in the upper area of the elevator door, the movement in the upper area of the elevator door being used to unlock the door leaf.
- the elastic element can be fixed at the fastening point or merely supported on this.
- the elastic element can be supported at the fastening point and can be stretched by displacing the energy storage device which moves the bolt into its locked position.

- the elastic element is formed by a spring element in such a way that the spring element moves the bolt into its unlocked position by moving the energy storage device. Accordingly, the energy accumulator has the effect that the elastic element formed by the spring element is in a state such that the extended arm of the bolt is not actuated when the energy accumulator is not moved by a service technician. When the energy store is moved by the service technician, the spring element is accordingly relieved or loaded and the bolt is thus moved into its unlocked position.
- a further development of the device comprises a rope, which rope is connected at its first end to the energy storage device and at its second end to the elastic element arranged at the fastening point. In this way, a connection is created between the energy store, which can be moved by the service technician, and the bolt.
- the energy store is formed by a closing weight or by a closing spring.
- a closing weight or such a closing spring can usually be arranged in the lower region of the door post of the corresponding door and can easily be reached or moved by a service technician.
- the door leaf is unlocked by pulling the energy store in the direction of a shaft pit or by lifting the energy store.

- such an elevator door comprises an energy store 32 connected to the door leaf 10 at a fastening point 36.
- the energy store 32 usually extends into the lower region of the elevator door and can be moved vertically within one of the two door posts. In the event of failure of the electrical energy supply necessary for the door drive, this energy storage device 32 closes the door leaf 10, i.e. its movement into the closed position, in order to be able to ensure the safety of people on the floor in the vicinity of the corresponding shaft door.
- the one in the Figures 1 and 2 energy storage device 32 shown is designed as a closing weight.
- the energy store 32 can also be designed as a closing spring or a similar element.
- a closing weight is coupled to the door leaf 10 in its upper area by means of a rope 34 in such a way that a vertical downward movement of the closing weight caused by the dead weight of the closing weight leads to a closure of the horizontally movable door leaf 10.
- the rope 34 is fixed at a first end to the closing weight, guided over a deflection roller 30 and connected to the fastening point 36 at its second end.
- the force for closing the door leaf 10 can be provided, for example, by the weight of the energy store 32 (closing weight) or its spring force (closing spring).

Description
Die Erfindung betrifft eine Vorrichtung zum Entriegeln einer Schachttür, eine Aufzugsanlage mit einer solchen Vorrichtung und ein Verfahren zum Entriegeln einer solchen Schachttür.The invention relates to a device for unlocking a shaft door, an elevator installation with such a device and a method for unlocking such a shaft door.
Eine Aufzugsanlage umfasst üblicherweise eine Aufzugskabine, die innerhalb eines Aufzugschachtes verfahren werden kann. Um Komponenten der Aufzugsanlage, beispielhaft den unteren Bereich der Aufzugskabine oder in der Schachtgrube des Aufzugsschachtes angeordnete Komponenten, einer Wartung zu unterziehen, steigt ein Servicetechniker durch eine unterste Schachttür in die Schachtgrube einAn elevator installation usually comprises an elevator car that can be moved within an elevator shaft. In order to subject components of the elevator system, for example the lower area of the elevator car or components arranged in the shaft pit of the elevator shaft, to maintenance, a service technician enters the shaft pit through a bottom shaft door
Die
Nach abgeschlossener Wartung in der Schachtgrube entriegelt der Servicetechniker die unterste Schachttür, um diese Schachttür öffnen und somit den Aufzugsschacht verlassen zu können. Üblicherweise befindet sich die entsprechende Verriegelungsvorrichtung der Schachttür im oberen Türbereich dieser Schachttür. Es ist bekannt, dass für eine Entriegelung aus dem Innern des Aufzugsschachtes ein Entriegelungsseil am Riegel der Verriegelungsvorrichtung fixiert sein kann, wobei sich dieses Entriegelungsseil von der Verriegelungsvorrichtung bis in den unteren Türbereich der Aufzugstür erstreckt. Der Servicetechniker kann dieses Entriegelungsseil ziehen, um die Aufzugstür zu entriegeln.After the maintenance in the shaft pit has been completed, the service technician unlocks the bottom shaft door in order to open this shaft door and thus to be able to leave the elevator shaft. The corresponding locking device of the shaft door is usually located in the upper door area of this shaft door. It is known that an unlocking cable can be fixed to the bolt of the locking device for unlocking from the inside of the elevator shaft, this unlocking cable extending from the locking device into the lower door area of the elevator door. The service technician can pull this release rope to unlock the elevator door.
Darüber hinaus weist eine jede Aufzugstür einen Kraftspeicher zur selbsttätigen Schliessung der Aufzugstür bei einem Ausfall der Stromversorgung auf. Nachteilig bei einer solchen Ausführung der Aufzugstür ist, dass das Vorhandensein des Kraftspeichers und der Entriegelungsvorrichtung einen komponentenreichen, also komplizierten, Aufbau der Vorrichtung darstellt.In addition, each elevator door has an energy store for automatic closing of the elevator door in the event of a power failure. The disadvantage of such an embodiment of the elevator door is that the presence of the energy storage device and the unlocking device represent a component-rich, that is to say complicated, construction of the device.
Daher ist es Aufgabe der Erfindung, eine Vorrichtung zum Entriegeln einer Aufzugstür bereitzustellen, welche einen vereinfachten Aufbau aufweist.It is therefore the object of the invention to provide a device for unlocking an elevator door which has a simplified structure.
Diese Aufgabe wird gelöst durch eine Vorrichtung zum Entriegeln einer Schachttür, wobei die Vorrichtung aufweist:
- ein Türblatt, welches zwischen einer Offenposition und einer Geschlossenposition verschiebbar ist,
- ein an dem Türblatt angeordneter Riegel zum Verriegeln des Türblattes in seiner Geschlossenposition,
- ein mit dem Türblatt gekoppelter Kraftspeicher, welcher Kraftspeicher bei Ausfall der für den Antrieb des Türblattes notwendigen Energieversorgung die Energie für die Bewegung des Türblattes in seine Geschlossenposition bereitstellt,
- a door leaf which can be moved between an open position and a closed position,
- a bolt arranged on the door leaf for locking the door leaf in its closed position,
- an energy storage device coupled to the door leaf, which energy storage device provides the energy for moving the door leaf into its closed position in the event of failure of the energy supply necessary to drive the door leaf,
Die Aufgabe wird ebenso gelöst durch eine Aufzugsanlage, welche mehrere übereinander angeordnete Schachttüren umfasst, durch welche Schachttüren der Aufzugschacht der Aufzugsanlage von mehreren übereinander angeordneten Stockwerken begehbar ist, wobei die Vorrichtung an einer untersten der Schachttüren angeordnet ist.The object is also achieved by an elevator system which comprises several shaft doors arranged one above the other, through which shaft doors the elevator shaft of the elevator system can be accessed from several floors arranged one above the other, the device being arranged on a lowermost of the shaft doors.
Die Aufgabe wird ebenso gelöst durch ein Verfahren zum Entriegeln einer Aufzugstür mit einer solchen Vorrichtung, wobei das Türblatt durch Verlagern des Kraftspeichers entriegelt wird.The object is also achieved by a method for unlocking an elevator door with such a device, the door leaf being unlocked by moving the energy store.
Der Erfindung liegt die Erkenntnis zugrunde, dass ein Kraftspeicher üblicherweise im unteren Bereich der Aufzugstür angeordnet und so für einen in der Schachtgrube befindlichen Servicetechniker leicht erreichbar ist, wenn diese Aufzugstür unmittelbar an der Schachtgrube angeordnet ist. Zum anderen ist dieser Kraftspeicher mit einem oberen Bereich der Aufzugstür bzw. des Türblattes gekoppelt, in welchem oberen Bereich ebenso der Riegel zur Verriegelung der Aufzugstür angeordnet ist. Mithilfe des elastischen Elements ist es demzufolge bei der Geschlossenstellung des Türblattes möglich, bei einer vorzugsweise manuellen Verlagerung des Kraftspeichers eine auf den Riegel wirkende Bewegung im oberen Bereich des Türblattes zu erzeugen. Diese im unteren Türbereich durchgeführte Bewegung wird dazu genutzt, den Riegel mittels des elastischen Elements im oberen Türbereich aus seiner verriegelten Stellung in seine entriegelte Stellung zu überführen und somit das Türblatt zur Öffnung freizugeben.The invention is based on the knowledge that an energy store is usually arranged in the lower area of the elevator door and is thus easily accessible to a service technician located in the shaft pit if this elevator door is arranged directly on the shaft pit. On the other hand, this energy store is coupled to an upper area of the elevator door or the door leaf, in which upper area the bolt for locking the elevator door is also arranged is. With the help of the elastic element, it is consequently possible, when the door leaf is in the closed position, to generate a movement in the upper area of the door leaf which acts on the bolt when the energy storage mechanism is preferably shifted manually. This movement carried out in the lower door area is used to transfer the bolt from its locked position to its unlocked position by means of the elastic element in the upper door area and thus to release the door leaf for opening.
Elastische Elemente im Sinne dieser Beschreibung umfassen ebenso Vorrichtungen, welche durch das Verlagern des Kraftspeichers zum Zweck der Entriegelung eine Längenänderung erfahren, wobei diese Längenänderung rückgängig gemacht wird, wenn der Kraftspeicher seine der Verriegeltenstellung des Riegels entsprechende Ausgangsposition wieder einnimmt.Elastic elements within the meaning of this description also include devices that experience a change in length by moving the energy store for the purpose of unlocking, this change in length being reversed when the energy store returns to its starting position corresponding to the locked position of the bolt.
Bei einer Weiterbildung der Vorrichtung ist der Kraftspeicher mittels eines am Türblatt angeordneten Befestigungspunktes mit dem Türblatt gekoppelt. Derart kann sichergestellt werden, dass die Bewegung des Kraftspeichers bei geöffnetem Türblatt ein Schließen des Türblattes bewirkt.In a further development of the device, the energy store is coupled to the door leaf by means of a fastening point arranged on the door leaf. In this way it can be ensured that the movement of the energy store causes the door leaf to close when the door leaf is open.
Bei einer Weiterbildung der Vorrichtung ist das elastische Element am Befestigungspunkt abgestützt und durch das den Riegel in seine Verriegeltenstellung versetzende Verlagern des Kraftspeichers entspannbar. Derart ist erreichbar, dass die Bewegung des Kraftspeichers im unteren Bereich der Aufzugstür eine Bewegung im oberen Bereich der Aufzugtür bewirkt, wobei die Bewegung im oberen Bereich der Aufzugtür zur Entriegelung des Türblattes genutzt wird. Das elastische Element kann zu diesem Zweck am Befestigungspunkt fixiert oder lediglich an diesem abgestützt sein.In a further development of the device, the elastic element is supported at the fastening point and can be relaxed by displacing the energy store, which moves the bolt into its locked position. In this way it can be achieved that the movement of the energy store in the lower area of the elevator door causes a movement in the upper area of the elevator door, the movement in the upper area of the elevator door being used to unlock the door leaf. For this purpose, the elastic element can be fixed at the fastening point or merely supported on this.
Das elastische Element kann am Befestigungspunkt abgestützt sein und durch das den Riegel in seine Verriegeltenstellung versetzende Verlagern des Kraftspeichers dehnbar sein. Mittels eines am Seil fixierten Betätigungselementes kann demnach der verlängerte Arm des Riegels so verschwenkt werden, dass der Riegel seine Entriegeltenstellung einnimmt.The elastic element can be supported at the fastening point and can be stretched by displacing the energy storage device which moves the bolt into its locked position. By means of an actuating element fixed on the rope, it is therefore possible the extended arm of the bolt can be pivoted so that the bolt assumes its unlocked position.
Bei einer Weiterbildung der Vorrichtung ist das elastische Element durch ein Federelement derart ausgebildet, dass das Federelement durch ein Verlagern des Kraftspeichers den Riegel in seine Entriegeltenstellung versetzt. Demnach bewirkt der Kraftspeicher, dass das durch das Federelement gebildete elastische Element in einem Zustand ist, dass der verlängerte Arm des Riegels nicht betätigt ist, wenn der Kraftspeicher nicht von einem Servicetechniker bewegt ist. Bei der Verlagerung des Kraftspeichers durch den Servicetechniker wird demnach das Federelement entlastet bzw. belastet und somit der Riegel in seiner entriegelten Stellung bewegt.In a further development of the device, the elastic element is formed by a spring element in such a way that the spring element moves the bolt into its unlocked position by moving the energy storage device. Accordingly, the energy accumulator has the effect that the elastic element formed by the spring element is in a state such that the extended arm of the bolt is not actuated when the energy accumulator is not moved by a service technician. When the energy store is moved by the service technician, the spring element is accordingly relieved or loaded and the bolt is thus moved into its unlocked position.
Eine Weiterbildung der Vorrichtung umfasst ein Seil, welches Seil an seinem ersten Ende mit dem Kraftspeicher und an seinem zweiten Ende mit dem an dem Befestigungspunkt angeordneten elastischen Element verbunden ist. Derart wird eine Verbindung zwischen dem durch den Servicetechniker bewegbaren Kraftspeicher und dem Riegel geschaffen.A further development of the device comprises a rope, which rope is connected at its first end to the energy storage device and at its second end to the elastic element arranged at the fastening point. In this way, a connection is created between the energy store, which can be moved by the service technician, and the bolt.
Bei einer Weiterbildung der Vorrichtung ist der Kraftspeicher durch ein Schließgewicht oder durch eine Schließfeder gebildet. Ein solches Schließgewicht bzw. eine solche Schließfeder sind üblicherweise im unteren Bereich des Türpfostens der entsprechenden Tür anordenbar und leicht von einem Servicetechniker erreich- bzw. bewegbar.In a further development of the device, the energy store is formed by a closing weight or by a closing spring. Such a closing weight or such a closing spring can usually be arranged in the lower region of the door post of the corresponding door and can easily be reached or moved by a service technician.
Bei einer Weiterbildung des Verfahrens wird das Türblatt durch ein in Richtung einer Schachtgrube gerichtetes Ziehen des Kraftspeichers oder durch Anheben des Kraftspeichers entriegelt. Derart sind mehrere Möglichkeiten gegeben, dass Verfahren durchzuführen. Bei einer Konstellation, die ein Entriegeln der Schachttür durch ein nach unten gerichtetes Ziehen des Kraftspeichers bewirkt, ist es von Vorteil, dass durch ein gegebenenfalls gerissenes Seil die Schachttür nicht entriegelt ist.In a further development of the method, the door leaf is unlocked by pulling the energy store in the direction of a shaft pit or by lifting the energy store. In this way, there are several options for carrying out the process. In a constellation which unlocks the shaft door by pulling the energy storage device downwards, it is advantageous that the shaft door is not unlocked by a possibly broken rope.
