Description

Vorrichtung zum Entriegeln einer Schachttür  Device for unlocking a landing door
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 landing door, an elevator installation with such a device and a method for unlocking such a landing 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 ein. An elevator installation usually comprises an elevator car which can be moved within an elevator shaft. In order to subject components of the elevator installation, for example the lower area of the elevator cage or components arranged in the shaft pit of the elevator shaft, to maintenance, a service technician enters the shaft pit through a lowermost shaft door.
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 maintenance in the pit has been completed, the service technician unlocks the bottom landing door to open this shaft door and thus leave the elevator shaft. Usually, the corresponding locking device of the shaft door is located in the upper door area of this shaft door. It is known that, for unlocking from the interior of the elevator shaft, an unlocking cable can be fixed to the latch of the locking device, this unlocking cable extending from the locking device into the lower door region of the elevator door. The service technician can pull this release cable to unlock the elevator door.
Darüber hinaus weist eine jede Aufzugstür einen Kraftspeicher zur selbsttätigen Schliessung der Aufzugstür bei einem Ausfall der Stromversorgung auf. In addition, each elevator door has a force storage device for the automatic closure of the elevator door in the event of a power failure.
Nachteilig bei einer solchen Ausführung der Aufzugstür ist, dass das Vorhandensein des Kraftspeichers und der Entriegelungsvorrichtung einen komponentenreichen, also komplizierten, Aufbau der Vorrichtung darstellt. A disadvantage of such an embodiment of the elevator door is that the presence of the energy storage device and the unlocking device is a component-rich, so complicated, construction of the device.
Daher ist es Aufgabe der Erfindung, eine Vorrichtung zum Entriegeln einer Aufzugstür bereitzustellen, welche einen vereinfachten Aufbau aufweist. Diese Aufgabe wird gelöst durch eine Vorrichtung zum Entriegeln einer Schachttür, wobei die Vorrichtung aufweist: It is therefore an object of the invention to provide a device for unlocking an elevator door, which has a simplified structure. This object is achieved by a device for unlocking a shaft door, the device comprising:
- ein Türblatt, welches zwischen einer Offenposition und einer Geschlossenposition verschiebbar ist,  a door leaf which is displaceable between an open position and a closed position,
- ein an dem Türblatt angeordneter Riegel zum Verriegeln des Türblattes in seiner Geschlossenposition,  a latch arranged on the door leaf for locking the door leaf in its closed position,
- 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 force accumulator which is coupled to the door leaf and which provides energy for the movement of the door leaf into its closed position upon failure of the energy supply necessary for driving the door leaf,
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. wherein the energy storage device is coupled by means of an elastic element with the door leaf, that by displacing the energy storage device in the arranged in its closed position door leaf, the bolt is displaceable in its unlocked 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 installation, which comprises a plurality of shaft doors arranged one above the other, through which shaft doors of the elevator shaft of the elevator installation can be walked by a plurality of floors arranged one above the other, the device being arranged on a lowermost one 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, wherein the door leaf is unlocked by displacing the force accumulator.
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 an- geordnet 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 finding that a force storage device is usually arranged in the lower region of the elevator door and thus easily accessible for a service technician located in the shaft pit when this elevator door is arranged directly on the shaft pit. On the other hand, this energy accumulator is coupled to an upper region of the elevator door or of the door leaf, in which upper region the latch for locking the elevator door is also connected. is ordered. With the aid of the elastic element, it is consequently possible in the closed position of the door leaf to generate a movement on the latch in the upper region of the door leaf in the case of a preferably manual displacement of the force accumulator. This movement performed in the lower door area is used to transfer the latch 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 to the 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 in the sense of this description also include devices which undergo a change in length by displacing the force accumulator for the purpose of unlocking, this change in length being reversed when the force accumulator resumes its starting position corresponding to the locked position of the latch.
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 accumulator is coupled to the door leaf by means of an attachment point arranged on the door leaf. In this way it can be ensured that the movement of the energy accumulator causes the door leaf to be closed when the door leaf is open.
Bei einer Weiterbildung der Vorrichtung ist das elastische Element am Befesti- gungspunkt 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 relieved by the displacement of the force accumulator displacing the latch into its locking position. It is thus possible to achieve that the movement of the energy store in the lower region of the elevator door causes a movement in the upper region of the elevator door, wherein the movement in the upper region of the elevator door is used for unlocking the door leaf. The elastic element may be fixed for this purpose at the attachment 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 may be supported at the attachment point and be extensible by the relocation of the force accumulator displacing the latch into its locked position. By means of a fixed to the rope actuator can therefore the extended arm of the bolt are 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 such that the spring element displaces the bolt into its unlocked position by displacing the force accumulator. Thus, the force accumulator causes the elastic member formed by the spring member to be in a state that the extended arm of the latch is not operated when the force accumulator is not moved by a service technician. When relocating the force accumulator by the service technician therefore the spring element is relieved or loaded and thus moves the bolt in 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 Be- festigungspunkt angeordneten elastischen Element verbunden ist. Derart wird eine Verbindung zwischen dem durch den Servicetechniker bewegbaren Kraftspeicher und dem Riegel geschaffen. A refinement of the device comprises a cable, which cable is connected at its first end to the energy store and at its second end to the elastic element arranged at the attachment 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 development of the device of the energy storage is formed by a closing weight or by a closing spring.

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. Figures 1 and 2 show devices for unlocking an elevator door, the device shown in Figure 1 corresponds to prior art. The components of these devices shown here are usually visible from the interior of a hoistway. Such a device may be part of an elevator door, in particular a cabin or landing door. Preferably, such a device is formed on a bottom of stacked shaft doors.
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 covers the door opening 12 in its closed position. The door leaf 10 is movable between a closed position and an open position. The elevator door may also include other door leaves, both telescopic and central opening door systems can be equipped with such a device. The door frame has on both sides of the door opening 12 door posts and above this door opening 12, ie in the upper region of the elevator door, a cross member.
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 accumulator 32 connected to the door leaf 10 at an attachment point 36. The energy accumulator 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 case of failure of the necessary for the door drive electric power supply causes this energy storage 32, the closure of the door leaf 10, ie its movement to the closed position 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 energy accumulator 32 shown in FIGS. 1 and 2 is designed as a closing weight. Alternatively, the energy accumulator 32 may be formed as a closing spring or a similar element. Such a closing weight is coupled to the door leaf 10 in its upper region by means of a cable 34 such 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 cable 34 is fixed for this purpose at a first end to the closing weight, guided over a deflection roller 30 and connected at its second end to the attachment point 36. The force for closing the door leaf 10 may be provided by way of example by the weight of the energy accumulator 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 dem- nach 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. In addition, the device comprises a latch 16 arranged in the upper door region, which usually locks the door leaf 10 located in its closed position. The latch 16 may be pivotable about a pivot axis 18. In the locked state, the latch 16 is pivoted into a latch 20 in order to prevent an opening movement of the door leaf 10. The bolt 16 is after on the door leaf 10 and the case 20 on the door frame of the elevator door, preferably on the cross member, arranged or vice versa. In addition, the latch can be held by means of a spring in its locking the door leaf 10 position.
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. The device shown in Figure 1 additionally has an unlocking device 40, which makes it possible to unlock the elevator door shown in Figure 1 from a lower portion of the elevator door from the interior of the elevator shaft can.

The unlocking cable 44 extends from the latch 16 from the upper region of the elevator door to the region of a door sill on the underside of the door leaf 10. The course or positioning of the unlocking cable 40 is determined by guide elements 42 for guiding the unlocking cable 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 cable 44 must therefore be pulled to move the latch 16 out of the engagement of the latch 20 and thus the door leaf 10 from the closed position into its To move open position horizontally.

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. Figures 4a and 4b show an elastic member 60 'of a device according to a second embodiment variant, wherein the elastic member 60' is exemplified as a tension spring. The cable 34 is fixed to the elastic member 60 'at a point 61'. Such a tension spring may also be formed as a coil spring, disc spring or any other spring. The device shown in FIGS. 4 a and 4 b has the same or equivalent components compared to the device shown in FIGS. 2, 3 a and 3 b, which can be understood with reference to the reference symbols.
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 does not act directly on the extended arm 16.1 of the bolt 16 in the case of a displacement of the energy accumulator 32 in the relaxed state (see FIG. 4b) by a service technician. Instead, the second end 34' of the cable 34 is such reinforced, that the extended arm 16.1 of the bolt 16 is actuated by this second end 34 'in relaxed unloading device 60' for a pivoting movement of the bolt 16.
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. Figures 3a and 4a show the elastic element 60, 60 'in the tensioned state. This means that the energy accumulator 32 is not displaced, for example by a service technician. Accordingly, the latch 16 is in its the elevator door locking position, ie in engagement with the case 20. Accordingly, the door leaf is prevented from opening movement. According to FIG. 3 a, such an elastic element 60 in the tensioned state can be spaced apart from the bolt 16 or from an exemplary extended arm 16. 1 of the bolt 16, preferably between 5 and 50 mm.

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. FIGS. 3b and 4b show the elastic elements 60, 60 'in the relaxed state. The relaxed state of the elastic member 60 is by displacement of the force accumulator 32 shown by way of example in FIG. By way of example, this can be achieved by lifting the force accumulator 32 embodied as closing weight or by stretching or lifting the force accumulator 32 embodied as a closing spring. In its relaxed state, this elastic element 60 or the second end 34 'of the cable 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 the pivot axis 18. Accordingly, the latch 16 of the Intervention of the latch 20 is pivoted and the door leaf 10 unlocked. Thus, a service technician who has moved the power storage to unlock the elevator door, move the door leaf from 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. Figures 2, 3a, 3b, 4a, 4b show elastic elements 60, 60 'which cause the shaft door to be unlocked by a tear of the cable 34.
