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 JP H11 171441 A , EP 1 321 422 A1 und JP H04 292392 A offenbaren Vorrichtungen und Verfahren laut dem Stand der Technik.The JP H11 171441 A , EP 1 321 422 A1 and JP H04 292392 A disclose prior art devices and methods.

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,
wobei der Kraftspeicher derart mittels eines elastischen Elements mit dem Türblatt gekoppelt ist, dass durch ein Verlagern des Kraftspeichers bei dem in seiner Geschlossenstellung angeordneten Türblatt der Riegel in seine Entriegeltenstellung versetzbar ist.This object is achieved by a device for unlocking a shaft door, the device having:
  • 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,
wherein the energy store is coupled to the door leaf by means of an elastic element in such a way that the bolt can be moved into its unlocked position by moving the energy store in the door leaf arranged in its closed position.

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.

Die Figuren 1 und 2 zeigen Vorrichtungen zum Entriegeln einer Aufzugstür, wobei die in Figur 1 dargestellte Vorrichtung vorbekanntem Stand der Technik entspricht. Die hier dargestellten Komponenten dieser Vorrichtungen sind üblicherweise aus dem Innern eines Aufzugsschachtes sichtbar. Eine solche Vorrichtung kann Bestandteil einer Aufzugstür, insbesondere einer Kabinen- oder Schachttür sein. Vorzugsweise ist eine solche Vorrichtung an einer untersten von übereinander angeordneten Schachttüren ausgebildet.The Figures 1 and 2 show devices for unlocking an elevator door, the in Figure 1 The device shown corresponds to the prior art. The components of these devices shown here are usually visible from inside an elevator shaft. Such a device can be part of an elevator door, in particular a car or shaft door. Such a device is preferably formed on a lowermost of shaft doors arranged one above the other.

Eine Aufzugstür umfasst üblicherweise einen nicht dargestellten Türrahmen, welcher eine Türöffnung 12 umgibt, und ein Türblatt 10, welches in seiner Geschlossenposition die Türöffnung 12 verdeckt. Das Türblatt 10 ist zwischen einer Geschlossenposition und einer Offenposition bewegbar. Die Aufzugstür kann darüber hinaus noch weitere Türblätter umfassen, wobei sowohl teleskopisch als auch zentral öffnende Türsysteme mit einer solchen Vorrichtung ausgestattet sein können. Der Türrahmen weist beidseitig der Türöffnung 12 Türpfosten und oberhalb dieser Türöffnung 12, also im oberen Bereich der Aufzugstür, einen Querträger auf.An elevator door usually comprises a door frame, not shown, which surrounds a door opening 12, and a door leaf 10 which, in its closed position, covers the door opening 12. The door leaf 10 is movable between a closed position and an open position. The elevator door can also include further door leaves, both telescopic and centrally opening door systems can be equipped with such a device. The door frame has door posts on both sides of the door opening 12 and a cross member above this door opening 12, that is to say in the upper region of the elevator door.

Darüber hinaus umfasst eine solche Aufzugstür einen mit dem Türblatt 10 an einem Befestigungspunkt 36 verbundenen Kraftspeicher 32. Der Kraftspeicher 32 erstreckt sich üblicherweise in den unteren Bereich der Aufzugstür und senkrecht innerhalb eines der beiden Türpfosten bewegbar. Im Falle des Ausfalls der für den Türantrieb notwendigen Elektroenergieversorgung bewirkt dieser Kraftspeicher 32 die Schließung des Türblattes 10, also dessen Bewegung in die Geschlossenposition, um die Sicherheit von Personen auf dem Stockwerk in der Umgebung der entsprechenden Schachttür gewährleisten zu können.In addition, 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.

Der in den Figuren 1 und 2 dargestellte Kraftspeicher 32 ist als Schliessgewicht ausgebildet. Alternativ dazu kann der Kraftspeicher 32 auch als Schliessfeder oder einem ähnlichen Element ausgebildet sein. Ein solches Schliessgewicht ist mit dem Türblatt 10 in dessen oberen Bereich mittels eines Seiles 34 derart gekoppelt, dass eine durch das Eigengewicht des Schliessgewichtes bewirkte senkrechte Abwärtsbewegung des Schliessgewichtes zu einer Schließung des horizontal bewegbaren Türblattes 10 führt. Das Seil 34 ist zu diesem Zweck an einem ersten Ende am Schliessgewicht fixiert, über eine Umlenkrolle 30 geführt und an seinem zweiten Ende mit dem Befestigungspunkt 36 verbunden. Die Kraft zur Schliessung des Türblattes 10 kann beispielhaft durch das Eigengewicht des Kraftspeichers 32 (Schliessgewicht) oder dessen Federkraft (Schliessfeder) bereitgestellt sein.The one in the Figures 1 and 2 energy storage device 32 shown is designed as a closing weight. As an alternative to this, the energy store 32 can also be designed as a closing spring or a similar element. Such 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. For this purpose, 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).

Die Vorrichtung umfasst darüber hinaus einen im oberen Türbereich angeordneten Riegel 16, welcher üblicherweise das in seiner Geschlossenstellung befindliche Türblatt 10 verriegelt. Der Riegel 16 kann um eine Schwenkachse 18 schwenkbar sein. Im verriegelten Zustand ist der Riegel 16 in eine Falle 20 eingeschwenkt, um eine Öffnungsbewegung des Türblattes 10 zu verhindern. Der Riegel 16 ist demnach am Türblatt 10 und die Falle 20 am Türrahmen der Aufzugstür, vorzugsweise am Querträger, angeordnet oder vice versa. Darüber hinaus kann der Riegel mit Hilfe einer Feder in seiner das Türblatt 10 verriegelnden Stellung gehalten werden.The device also comprises a bolt 16 arranged in the upper door area, which usually locks the door leaf 10 in its closed position. The bolt 16 can be pivotable about a pivot axis 18. In the locked state, the bolt 16 is pivoted into a latch 20 in order to prevent the door leaf 10 from opening. The bolt 16 is accordingly on the door leaf 10 and the latch 20 on the door frame of the elevator door, preferably on the cross member, or vice versa. In addition, the bolt can be held in its position locking the door leaf 10 with the aid of a spring.

Die in Figur 1 gezeigte Vorrichtung weist zusätzlich eine Entriegelungsvorrichtung 40 auf, welche es ermöglicht, die in Figur 1 dargestellte Aufzugstür von einem unteren Bereich der Aufzugstür aus dem Innern des Aufzugsschachtes entriegeln zu können. Die Entriegelungsvorrichtung 40 umfasst ein Entriegelungsseil 44, welches Entriegelungsseil 44 mit dem Riegel 16 verbunden ist. Das Entriegelungsseil 44 erstreckt sich vom Riegel 16 vom oberen Bereich der Aufzugstür bis zum Bereich einer Türschwelle an der Unterseite des Türblattes 10. Der Verlauf bzw. die Positionierung des Entriegelungsseils 40 ist durch Führungselemente 42 zur Führung des Entriegelungsseils 40 am Türblatt 10 festgelegt.In the Figure 1 The device shown additionally has an unlocking device 40, which enables the in Figure 1 to be able to unlock illustrated elevator door from a lower area of the elevator door from inside the elevator shaft. The unlocking device 40 comprises an unlocking cable 44, which unlocking cable 44 is connected to the bolt 16. The unlocking rope 44 extends from the bolt 16 from the upper area of the elevator door to the area of a door sill on the underside of the door leaf 10. The course or the positioning of the unlocking rope 40 is determined by guide elements 42 for guiding the unlocking rope 40 on the door leaf 10.

Um eine mit einer solchen Entriegelungsvorrichtung 40 ausgestatteten verriegelten Aufzugstür zu entriegeln bzw. zu öffnen, muss demnach das untere Ende des Entriegelungsseiles 44 gezogen werden, um den Riegel 16 aus dem Eingriff der Falle 20 zu bewegen und so das Türblatt 10 aus der Geschlossenposition in seine Offenposition horizontal bewegen zu können. Ein solcher Riegel 16 kann beispielhaft durch Federkraft mittels einer nicht dargestellten Haltefeder in seiner Verriegeltenstellung gehalten werden. Durch das beschriebene Betätigen des Entriegelungsseiles 44 ist diese Federkraft temporär überwindbar.In order to unlock or open a locked elevator door equipped with such an unlocking device 40, the lower end of the unlocking rope 44 must accordingly be pulled to move the bolt 16 out of engagement of the latch 20 and thus the door leaf 10 from the closed position into its To be able to move the open position horizontally. Such a bolt 16 can, for example, be held in its locked position by spring force by means of a retaining spring (not shown). By actuating the unlocking cable 44 as described, this spring force can be temporarily overcome.

An dem in Figur 2 gezeigten Befestigungspunkt 36 ist ein elastisches Element 60 angeordnet. Das elastische Element 60 kann durch ein Federelement gebildet sein. Das Federelement ist einerseits am Befestigungspunkt 36 abgestützt und andererseits mit dem zweiten Ende des Seiles 34 verbunden.At the in Figure 2 An elastic element 60 is arranged in the fastening point 36 shown. The elastic element 60 can be formed by a spring element. The spring element is supported on the one hand at the fastening point 36 and on the other hand connected to the second end of the rope 34.

Die Figuren 3a und 3b zeigen einen Ausschnitt der in Figur 2 dargestellten Vorrichtung, insbesondere das am Riegel 16 angeordnete elastische Element 60. Das elastische Element 60 ist als Schraubenfeder, insbesondere als Druckfeder, dargestellt, kann aber auch als Tellerfeder oder jedwede andere Feder mit der gemäss den Figuren 3a und 3b gegebenen Wirkung ausgebildet sein.The Figures 3a and 3b show a section of the in Figure 2 illustrated device, in particular the elastic element 60 arranged on the bolt 16 elastic element 60 is shown as a helical spring, in particular as a compression spring, but can also be used as a plate spring or any other spring with the according to the Figures 3a and 3b given effect.

Die Figuren 4a und 4b zeigen ein elastisches Element 60' einer Vorrichtung gemäss einer zweiten Ausgestaltungsvariante, wobei das elastische Element 60' beispielhaft als Zugfeder dargestellt ist. Das Seil 34 ist an dem elastischen Element 60' an einem Punkt 61' fixiert. Eine solche Zugfeder kann ebenso als Schraubenfeder, Tellerfeder oder jedwede andere Feder ausgebildet sein. Die in den Figuren 4a und 4b dargestellte Vorrichtung weist im Vergleich zu der in den Figuren 2, 3a und 3b gezeigten Vorrichtung gleiche bzw. gleichwirkende Komponenten auf, was anhand der Bezugszeichen nachvollziehbar ist.The Figures 4a and 4b show an elastic element 60 'of a device according to a second variant embodiment, the elastic element 60' being shown by way of example as a tension spring. The rope 34 is fixed to the elastic element 60 'at a point 61'. Such a tension spring can also be designed as a helical spring, plate spring or any other spring. The ones in the Figures 4a and 4b The device shown has in comparison to that in the Figures 2 , 3a and 3b The device shown has the same or equivalent components, which can be understood using the reference numerals.

Das elastische Element 60' gemäss der zweiten Ausgestaltungsvariante wirkt bei einer durch einen Servicetechniker getätigten Verlagerung des Kraftspeichers 32 im entspannten Zustand (siehe Figur 4b) nicht direkt auf den verlängerten Arm 16.1 des Riegels 16. Stattdessen ist das zweite Ende 34' des Seils 34 derart verstärkt, dass der verlängerte Arm 16.1 des Riegels 16 durch dieses zweite Ende 34' bei entspannter Enlastungsvorrichtung 60' für eine Schwenkbewegung des Riegels 16 betätigbar ist.The elastic element 60 ′ according to the second embodiment variant acts when the energy store 32 is shifted by a service technician in the relaxed state (see FIG Figure 4b ) not directly onto the extended arm 16.1 of the bolt 16. Instead, the second end 34 'of the rope 34 is reinforced in such a way that the extended arm 16.1 of the bolt 16 passes through this second end 34' for a pivoting movement of the bolt 16 when the relief device 60 'is relaxed is actuatable.

Die Figuren 3a und 4a zeigen das elastische Element 60, 60' im gespannten Zustand. Das heisst, dass der Kraftspeicher 32 nicht, beispielhaft durch einen Servicetechniker, verlagert ist. Entsprechend befindet sich der Riegel 16 in seiner die Aufzugstür verriegelnden Stellung, also im Eingriff mit der Falle 20. Entsprechend ist das Türblatt an einer Öffnungsbewegung gehindert. Gemäss Figur 3a kann ein solches elastisches Element 60 im gespannten Zustand vom Riegel 16 bzw. von einem beispielhaft verlängerten Arm 16.1 des Riegels 16, vorzugsweise zwischen 5 und 50 mm, beabstandet sein.The Figures 3a and 4a show the elastic element 60, 60 'in the tensioned state. This means that the energy store 32 has not been relocated, for example by a service technician. Accordingly, the bolt 16 is in its position locking the elevator door, that is to say in engagement with the latch 20. The door leaf is accordingly prevented from opening movement. According to Figure 3a Such an elastic element 60 can, in the tensioned state, be spaced apart from the bolt 16 or from an arm 16.1 of the bolt 16 which is extended, for example, preferably between 5 and 50 mm.

Die Figuren 3b und 4b zeigen die elastischen Elemente 60, 60' im entspannten Zustand. Der entspannte Zustand des elastischen Elements 60 ist durch Verlagern des beispielhaft in Figur 2 dargestellten Kraftspeichers 32 erreichbar. Beispielhaft kann dies durch Anheben des als Schliessgewicht ausgebildeten Kraftspeichers 32 oder durch Dehnen oder Anheben des als Schliessfeder ausgebildeten Kraftspeichers 32 erreicht sein. In ihrem entspannten Zustand übt dieses elastische Element 60 bzw. das zweite Ende 34' des Seiles 34 eine Kraft auf den verlängerten Arm 16.1 des Riegels 16 aus und bewirkt damit eine Schwenkbewegung des Riegels 16 um dessen Schwenkachse 18. Entsprechend ist der Riegel 16 aus dem Eingriff der Falle 20 geschwenkt und das Türblatt 10 entriegelt. Somit kann ein Servicetechniker, welcher zur Entriegelung der Aufzugstür den Kraftspeicher bewegt hat, das Türblatt aus seiner Geschlossenposition in Richtung seiner Offenposition bewegen.The Figures 3b and 4b show the elastic elements 60, 60 'in the relaxed state. The relaxed state of the elastic member 60 is due to displacement the example in Figure 2 energy storage device 32 shown. For example, this can be achieved by lifting the energy store 32 designed as a closing weight or by stretching or lifting the energy store 32 designed as a closing spring. In its relaxed state, this elastic element 60 or the second end 34 'of the rope 34 exerts a force on the extended arm 16.1 of the bolt 16 and thus causes a pivoting movement of the bolt 16 about its pivot axis 18. Accordingly, the bolt 16 is from the Engagement of the latch 20 pivoted and the door leaf 10 unlocked. Thus, a service technician who has moved the energy store to unlock the elevator door can move the door leaf out of its closed position in the direction of its open position.

Die Figuren 2, 3a, 3b, 4a, 4b zeigen elastische Elemente 60, 60', welche bewirken, dass durch einen Riss des Seils 34 die Schachttür entriegelt ist.The Figures 2 , 3a , 3b , 4a, 4b show elastic elements 60, 60 ', which have the effect that the shaft door is unlocked when the cable 34 breaks.

Die Figuren 5a und 5b zeigen ein elastisches Element 60", welches an seinem ersten Ende am Befestigungspunkt 36 fixiert ist. Am zweiten Ende des elastischen Elements 60" ist das Seil 34 fixiert, wobei das Seil 34 entsprechend der in den Figuren 1 und 2 gezeigten Darstellung zum Kraftspeicher 32 weitergeführt sein kann. Das Seil 34 ist am verlängerten Arm 16.1 des Riegels 16 vorbeigeführt. Am Seil 34 bzw. am elastischen Element 60" kann ein Aktivierungselement 70 fixiert sein, welches bei einer Verlagerung des Kraftspeichers, insbesondere einem in Richtung der Schwerkraft gerichteten Ziehen des Kraftspeichers den verlängerten Arm 16.1 des Riegels 16 betätigt, so dass der Riegel 16 in seine Entriegeltenstellung geschwenkt wird.The Figures 5a and 5b show an elastic element 60 ″, which is fixed at its first end to the fastening point 36. The rope 34 is fixed at the second end of the elastic element 60 ″, the rope 34 being continued to the energy store 32 in accordance with the illustration shown in FIGS can be. The rope 34 is guided past the extended arm 16.1 of the bolt 16.
