Beschreibung description
Die Erfindung betrifft eine Aufzugsanlage mit einem Aufzugsschacht, der eine Schachtgrube bzw. einen Schachtkopf mit minimaler Höhe oder gar keine Schachtgrabe bzw. Schachtkopf umfasst. The invention relates to an elevator installation with an elevator shaft which comprises a shaft pit or a shaft head with a minimum height or no shaft pit or shaft head.
Aufzugsanlagen umfassen üblicherweise v e tri egel bare Schachttüren. Solche Schachttüren sind mittels eines Schlüssels vom Stockwerk unabhängig von einer Position der Aufzugskabine entriegelbar, so dass beispielsweise ein Servicetechniker zur Wartung der Aufzugsaniage in die Schachtgrube oder auf die Aufzugskabine steigen kann. Vorschriften bzw. Normen schreiben in einem solchen Fall vor, dass der Aufzugsschacht einen Schutzraum im Schachtkopf bzw. in der Schachtgrube aufweisen muss, in welchen Schutzraum die Aufzugskabine nicht verfahren werden kann. Derart kann der im Aufzugsschacht ausserhalb der Aufzugskabine befindliche Servicetechniker selbst während eines Verfahrens der Aufzugskabine geschützt werden. Entsprechend muss die Schachtgrube bzw. der Schachtkopf eine Mindesthöhe aufweisen. Elevator systems usually include pivotable shaft doors. Such shaft doors can be unlocked by means of a key from the floor independently of a position of the elevator car, so that, for example, a service technician can climb into the shaft pit or onto the elevator car for maintenance of the elevator system. Regulations or standards stipulate in such a case that the elevator shaft must have a shelter in the shaft head or in the pit in which shelter the elevator car can not be moved. In this way, the service technician located in the elevator shaft outside the elevator car can be protected even during a process of the elevator car. Accordingly, the shaft pit or the shaft head must have a minimum height.
Vermehrt besteht jedoch die Anforderung, die Schachtgraben- bzw. die Schachtkopfhöhe weiter zu reduzieren. In der Patentschrift EP 1604934 ist beispielhaft eine Aufzugsaniage mit einem auf einer Aufzugskabine angeordneten Kontrollkasten gezeigt. Ein auf der Aufzugskabine befindlicher Wartungstechniker öffnet diesen Kontrollkasten, was einHowever, there is an increasing demand to further reduce the pit trench height. Patent specification EP 1604934 shows by way of example an elevator system with a control box arranged on an elevator car. A maintenance technician located on the elevator car opens this control box, which is a
Ausfahren von an der Aufzugskabine angeordneten Sperrmitteln bewirkt. Die Sperrmittel verhindern in ihrem ausgefahrenen Zustand, dass die Aufzugskabine während der War- tungsarbeiten in den Schutzraum oberhalb der Aufzugskabine eindringen kann. Extending effected by the elevator car locking means causes. In their extended state, the blocking means prevent the elevator car from penetrating into the shelter above the elevator car during the maintenance work.
Nachteilig ist dabei, dass die technische Realisierung einer solchen Lösung eine komplizierte Mechanik erfordert. The disadvantage here is that the technical realization of such a solution requires a complicated mechanism.
Es ist daher Aufgabe der Erfindung, eine Aufzugsaniage bereitzustellen, bei der trotz verringerter Höhe des Schachtkopfes bzw. der Schachtgrube ein notwendiger Schutzraum jederzeit gewährleistet werden kann. Die Aufgabe wird gelöst durch eine Aufzugsanlage mit einer an einem Stockwerk angeordneten Schachttür, einer Aufzugskabine, einer an der Schachttür angeordneten Türrie- gel zum Verriegeln der Schachttür, welcher Türriegel zur Entriegelung der Schachttür von einer dem Stockwerk zugewandten Seite der Schachttür mittels eines Schlüssels aus einer Verriegeltstellung in eine Entriegeltstellung bringbar ist, einem Blockierelement, das in seiner Blockierstellung eine Öffnung der Schachttür verhindert, und einem auf das Blockierelement wirkenden Aktuator, wobei der Aktuator derart ausgebildet ist, dass die Blockierstellung des Blockierelementes ausschliesslich aufgehoben ist, wenn die Aufzugskabine innerhalb einer der Schachttür zugeordneten Notbefreiungszone angeordnet ist. It is therefore an object of the invention to provide a Aufzugsaniage, in spite of reduced height of the shaft head and the pit a necessary shelter can be guaranteed at any time. The object is achieved by an elevator installation having a shaft door arranged on a floor, an elevator car, a door hinge arranged on the shaft door for locking the shaft door, which door latch for unlocking the shaft door from a side of the shaft door facing the floor by means of a key Locked position can be brought into an unlocked position, a blocking element which prevents an opening of the shaft door in its blocking position, and an actuator acting on the blocking element, wherein the actuator is designed such that the blocking position of the blocking element is canceled exclusively if the elevator car within one of Shaft door assigned emergency release zone is arranged.
Personen, die beispielhaft an der installierten Aufzugsanlage Arbeiten verrichten, sind gegebenenfalls durch bewegbare Teile der Aufzugsanlage, insbesondere die Aufzugskabine, gefährdet. Entsprechend sind in der Aufzugsanlage gemäss gängiger Vorschriften Schutzräume in für Personen bestimmten Aufenthaltsbereichen angeordnet. Die bewegbaren Teile der Aufzugsanlage können nicht in diese Schlitzräume eindringen. Derart kann verhindert werden, dass ein sich beispielsweise in der Schachtgrube oder im Schachtkopf befindlicher Servicetechniker durch Verfahren der Aufzugskabine im Aufzugsschacht verletzt wird. Der Servicetechniker kann sich in den Schutzraitm begeben, wenn sich die Aufzugskabine in Richtung ihrer untersten bzw. obersten möglichen Position im Aufzugsschacht bewegt. Persons who perform works by way of example on the installed elevator installation are possibly endangered by movable parts of the elevator installation, in particular the elevator car. Accordingly, in the elevator installation according to current regulations, shelters are arranged in accommodation areas intended for persons. The moving parts of the elevator system can not penetrate into these slot spaces. In this way, it is possible to prevent a service technician located, for example, in the shaft pit or in the shaft head from being injured by moving the elevator cage in the elevator shaft. The service technician can go into the protective portrait when the elevator car moves in the direction of its lowest or highest possible position in the elevator shaft.
Zunehmend besteht jedoch das Erfordernis, dass Aufzugsschächte möglichst geringe Abmessungen aufweisen. Entsprechend können die Schachtgrube und/oder der Schachtkopf des jeweiligen Aufzugsschachtes derart gering bemessen sein, dass ausserhalb, also unter bzw. über der Aufzugskabine kein vollständiger, gemäss den gängigen Vorschriften vorzusehender Schutzraum anordenbar ist. Increasingly, however, there is a requirement that elevator shafts have the smallest possible dimensions. Accordingly, the shaft pit and / or the shaft head of the respective elevator shaft can be dimensioned so small that outside, ie below or above the elevator car, no complete, according to the current regulations to be provided protective space can be arranged.
Es wurde demnach versucht, die Ausgestaltung der Aufzugsanlage so zu verändern, dass ein solcher Schutzraum bzw. Schutzräume im Aufzugsschacht ausserhalb der Aufzugskabine nicht notwendig sind. Dies wird erreicht, indem die Schachttüren so ausgeführt sind, dass ein direkter Zugang vom Stockwerk in den Aufzugsschacht verunmöglicht ist. Die Schachttür ist demnach ausschliesslich offenbar, wenn die Aufzugskabine derart an der Schachttür angeordnet ist, dass der direkte Zugang vom Stockwerk in den Aufziigsschacht versperrt ist. Ist die Aufzugskabine in einer solchen Position angeordnet, ist die Blockiersteüung des Blockierelementes aufgehoben, das heisst, dass das Blockierelement seine Freigabestellung einnimmt. Zusätzlich zu Türöffnungen der Schachttür im Normalbetrieb, die üblicherweise durch einen Türantrieb bewirkt werden, bleibt die Schachttür mittels des Schlüssels entriegelbar, um beispielsweise Personen bei Störungen der Aufzugsanlage aus der Aufzugskabine notbefreien zu können. Ist die Aufzugskabine hingegen an einer anderen Position, also nicht innerhalb der Notbefreiungszone angeordnet, ist die Schachttür unabhängig von der Verriegeltenstellung bzw. Entriegeltenstellung des Türriegels unter keinen Umständen offenbar. It was therefore attempted to change the design of the elevator system so that such a shelter or shelters in the elevator shaft outside the elevator car are not necessary. This is achieved by the shaft doors are designed so that direct access from the floor into the elevator shaft is impossible. The landing door is therefore exclusively apparent when the elevator car so on the Shaft door is arranged that the direct access from the floor is blocked in the Aufziigsschacht. If the elevator car is arranged in such a position, the blocking control of the blocking element is released, that is, the blocking element assumes its release position. In addition to door openings of the landing door in normal operation, which are usually effected by a door drive, the shaft door remains unlockable by means of the key, for example, to emergency persons in case of faults in the elevator system from the elevator car can. If, however, the elevator car is located at a different position, ie not within the emergency release zone, the shaft door is under no circumstances apparent, regardless of the locked position or unlocked position of the door bolt.
Der Aktuator ist demnach derart ausgebildet, dass die Blockierstellung des Blockierelementes ausschliesslich aufgehoben ist, wenn die Aufzugskabine innerhalb der derThe actuator is thus designed such that the blocking position of the blocking element is exclusively canceled if the elevator car within the
Schachttür zugeordneten Notbefreiungszone angeordnet ist. Das bedeutet, dass der Aktuator zur Aufhebung der Blockierstellung ausschliesslich dann vorgesehen ist, wenn die Aufzugskabine innerhalb dieser Notbefreiungszone angeordnet ist. Shaft door assigned emergency release zone is arranged. This means that the actuator for canceling the blocking position is provided exclusively when the elevator car is arranged within this emergency release zone.
Die Aufzugskabine gilt als in der Notbefreiungszone der Schachttür angeordnet, wennThe elevator car is considered to be located in the emergency exemption zone of the landing door when
Personen bei geöffneter Schachttür ein Zugang in den Aufziigsschacht durch die an dieser Schachttür angeordnete Aufzugskabine gänzlich versperrt ist. Gemäss der vorliegenden Beschreibung sind Personen, die sich in einem Aufzugsschacht der Aufzugsanlage befinden oder diesen betreten haben, als Personen zu verstehen, die sich ausserhalb des Innenraumes der Aufzugskabine im Aufziigsschacht befinden. Persons with the shaft door open access into the Aufziigsschacht is completely obstructed by arranged on this shaft door elevator car. According to the present description, persons who are located in or enter an elevator shaft of the elevator installation are to be understood as persons who are outside the interior of the elevator cage in the attachment shaft.
Eine Weiterbildung der Aufzugsanlage weist mehrere im Wesentlichen übereinander angeordnete Schachttüren auf, wobei eine unterste der Schachttüren und/oder eine oberste der Schachttüren jeweils den Türriegel und das Blockierelement aufweisen. Durch eine Anordnung des erfindungsgemässen Türriegels und des erfindungsgemässen Blockierelementes an der untersten Schachttür kann verunrnögiicht werden, dass eine Person durch die unterste Schachttür in die Schachtgrube gelangen kann. Durch eine zusätzliche oder alternative Anordnung des erfindungsgemässen Türriegels und des erfindungsgemässen Blockierelementes an der obersten Schachttür kann verunrnögiicht werden, dass eine Person durch die oberste Schachttür auf die Aufzugskabine gelangen kann. Derart kann eine Gefährdung dieser Personen verhindert werden, wenn der Schachtkopf bzw. die Schachtgrube zu geringe Abmessungen zur Anordnung eines Schutzraumes ausserhalb der Aufzugskabine aufweisen. Darüber hinaus kann an allen Schachttüren der Aufzugsanlage ein solcher Türriegel und ein solches Blockierelement angeordnet sein, um den direkten Zugang von irgendeinem Stockwerk in den Aufzugsschacht durch eine der Schachttüren zu verunmöglichen. A development of the elevator system has a plurality of substantially stacked shaft doors, wherein a lowermost of the shaft doors and / or a top of the shaft doors each have the door latch and the blocking element. By arranging the inventive door bolt and the blocking element according to the invention on the lowermost shaft door, it can be obscured that a person can reach the shaft pit through the lowermost shaft door. An additional or alternative arrangement of the inventive door bolt and the blocking element according to the invention on the uppermost shaft door can make it impossible for a person to reach the elevator car through the uppermost shaft door. Such a danger to these persons can be prevented if the shaft head or the Shaft pit to have small dimensions for the arrangement of a shelter outside the elevator car. In addition, at all shaft doors of the elevator installation, such a door latch and such a blocking element can be arranged in order to prevent the direct access of any floor into the elevator shaft through one of the shaft doors.
Bei einer Weiterbildung der Aufzugsanlage weist die Aufzugskabine einen zumindest teilweise als Bodenklappe ausgebildeten Kabinenboden und/oder ein teilweise als Dachklappe ausgebildetes Kabinendach aufweist, wobei sich ein Schutzraum für in einem Schachtkopf bzw. in einer Schachtgrube der Aufzugsanlage befindliches Servicepersonal bei geöffneter Dach- oder Bodenklappe in die Aufziigskabine erstreckt. Vorteilhaft ist, dass Servicepersonal trotz einer nicht vorhandenen direkten Zugänglichkeit der Schachtgrube bzw. des Schachtkopfes durch die Schachttür dennoch Wartungsarbeiten in der Schachtgrube bzw. im Schachtkopf durchführen kann. Bei geöffneter Boden- bzw. Dachklappe ist somit der Schutzraum zumindest zum Teil in der Aufzugskabine angeordnet. Das heisst, dass derart in den Aufzugsschacht der Aiifzugsanlage, insbesondere in den Schachtkopf bzw. in die Schachtgrube, eingedrungene Personen geschützt werden können. In a further development of the elevator installation, the elevator car has a cabin floor which is at least partly designed as a floor flap and / or a canopy partially designed as a roof flap, wherein a shelter for service personnel located in a shaft head or in a shaft pit of the elevator installation is open when the roof or floor flap is open extending the Aufziigskabine. It is advantageous that service personnel can still carry out maintenance work in the shaft pit or in the shaft head despite a lack of direct accessibility to the shaft pit or the shaft head through the shaft door. When the floor or roof flap is open, the shelter is thus at least partially arranged in the elevator car. This means that such persons can be protected in the elevator shaft of the Aiifzugsanlage, in particular in the shaft head or in the pit, invaded persons.
Bei einer Weiterbildung der Aufzugsanlage ist der Aktuator an der Aufzugskabine angeordnet. Mittels einer solchen Anordnung kann eine Ausfallwahrscheinlichkeit der Aiifzugsanlage durch einen fehlfunktionierenden Aktuator verringert werden, weil der Aktuator direkt, vorzugsweise aus unmittelbarer örtlicher Nähe, auf das Blockierelement wirken kann, wenn die Aufzugskabine innerhalb der der Schachttür zugeordneten Notbefrei- ungszone angeordnet ist. In a further development of the elevator installation, the actuator is arranged on the elevator car. By means of such an arrangement, a probability of failure of the Aiifzugsanlage can be reduced by a malfunctioning actuator, because the actuator directly, preferably from immediate local proximity, can act on the blocking element, when the elevator car is located within the shaft door associated emergency release zone.
Bei einer Weiterbildung der Aufzugsanlage ist das Blockierelement derart ausgebildet, dass das Blockierelement in seiner Blockierstellung den Türriegel in seiner Verriegeltenstellung blockiert. Alternativ dazu kann die Schachttür der Aufzugsanlage ein Türblatt aufweisen und das Blockierelement derart ausgebildet sein, dass das Blockierelement in seiner Blockierstellimg das Türblatt in seiner Geschlossenstellung blockiert. Derart kann realisiert werden, dass das Blockierelement in seiner Blockierstellung eine Öffnung der Schachttür verhindert, Bei einer Weiterbildung der Aufzugsanlage ist der Aktuator eine Führungskurve oder ein elektrisches Schaltmittel, Alternativ dazu kann der Aktuator eine Positionserfassungsein- heit zur Erfassung einer Position der Aufzugskabine im Aufzugsschacht der Aufzugsanlage sein, Mittels eines solchen Aktuators kann das Blockierelement beeinflusst werden. In a development of the elevator system, the blocking element is designed such that the blocking element blocks the door bolt in its locked position in its locked position. Alternatively, the shaft door of the elevator installation may have a door leaf and the blocking element may be designed such that the blocking element blocks the door leaf in its closed position in its blocking position. In this way, it can be realized that the blocking element in its blocking position prevents an opening of the shaft door, In a development of the elevator installation, the actuator is a guide curve or an electrical switching means. Alternatively, the actuator can be a position detection unit for detecting a position of the elevator cage in the elevator shaft of the elevator installation. By means of such an actuator, the blocking element can be influenced.

Figur 1 zeigt eine Aufzugsanlage 2 mit einer in einem Aufzugsschacht 3 verfahrbaren Aufzugskabine 10. Der Aufzugsschacht 3 weist an seinem oberen Ende einen Schachtkopf 5 und an seinem unteren Ende eine Schachtgriibe 7 auf. Der Schachtkopf 5 und/oder die Schachtgrube 7 können derart klein bemessen sein, dass ein vorzusehener Schutzraum 16 nicht vollständig ausserhalb der Aufzugskabine 10 anordenbar ist. Ein solcher Schutzraum 16 bildet gemäss den üblichen Vorschriften genügend Raum für eine im Aufzugsschacht 3 befindliche Person, wenn die Aufziigskabine 10 in ihrer untersten bzw. obersten möglichen Stellung im Aufzugsschacht 3 angeordnet ist. Der Aufzugsschacht 3 verbindet mindestens zwei Stockwerke 8.1, 8.2, 8.3. An jedem Stockwerk 8.1 , 8.2, 8.3 ist eine Schachttür 4.1 , 4.2, 4.3 angeordnet, um den Aufzugsschacht 3 verschliessen zu können. FIG. 1 shows an elevator installation 2 with an elevator car 10 that can be moved in an elevator shaft 3. The elevator shaft 3 has a shaft head 5 at its upper end and a shaft shaft 7 at its lower end. The shaft head 5 and / or the shaft pit 7 can be sized so small that a protective space 16 to be provided can not be arranged completely outside the elevator car 10. Such a shelter 16 forms according to the usual regulations sufficient space for a person located in the elevator shaft 3 person when the Aufziigskabine 10 is disposed in its lowest or highest possible position in the elevator shaft 3. The elevator shaft 3 connects at least two floors 8.1, 8.2, 8.3. At each floor 8.1, 8.2, 8.3 a landing door 4.1, 4.2, 4.3 is arranged to close the elevator shaft 3 can.
Figur 2 zeigt eine Aufzugskabine 10, die an einem Stockwerk 8 angeordnet ist. Die Aufzugskabine 10 weist einen Kabinenboden 1 1 auf. Das Stockwerk 8 weist einen Stock- werksboden 9 auf. Am Stockwerk 8 ist eine ein Türblatt 6 umfassende Schachttür 4 angeordnet. An der Schachttür 4 ist ein Türriegel 32 zur Verriegelung der Schachttür 4 angeordnet. In seiner Verriegeltenstellung verhindert der Türriegel 32 eine Öffnung der Figure 2 shows an elevator car 10, which is arranged on a floor 8. The elevator car 10 has a cabin floor 1 1. The floor 8 has a floor factory floor 9 up. On the floor 8 a door leaf 6 comprehensive shaft door 4 is arranged. At the landing door 4, a door latch 32 is arranged to lock the landing door 4. In its locked position, the door latch 32 prevents opening of the
Schachttür 4. Das heisst, dass das Türblatt 6 bei verriegelter Schachttür 4 nicht aus seiner Geschlossenstellung bewegt werden kann.  Shaft door 4. This means that the door leaf 6 can not be moved out of its closed position when the shaft door 4 is locked.
Die Schachttür 4 ist üblicherweise mittels eines nicht dargestellten Türantriebes offenbar, wenn die Aufzugskabine 10 an der Schachttür 4 angeordnet ist. Unerheblich ist dabei, ob der Türantrieb an der Aufzugskabine 10 oder an der Schachttür 4 angeordnet ist. Bei unmittelbar bevorstehender Öffnung der Schachttür 4 mittels des Türantriebs ist der Türantrieb derart mit der Schachttür 4 gekoppelt, dass der Türriegel 32 mittels des Türantriebs aus seiner Verriegelten- in seine Entriegeltenstellung bringbar ist. Wenn der Türriegel 32 daraufhin in seine Entriegeltenstellung überführt ist, kann die Schachttür 4 durch eine Öffnungsbewegung des Türblattes 6 zumindest teilweise geöffnet werden. The shaft door 4 is usually apparent by means of a door drive, not shown, when the elevator car 10 is arranged on the shaft door 4. It is irrelevant whether the door drive is arranged on the elevator car 10 or on the shaft door 4. In the case of imminent opening of the shaft door 4 by means of the door drive, the door drive is coupled to the shaft door 4 in such a way that the door latch 32 can be brought out of its locked position into its unlocked position by means of the door drive. If the door bolt 32 is then transferred to its unlocked position, the shaft door 4 can be at least partially opened by an opening movement of the door leaf 6.
Es ist möglich, dass die Schachttür 4 geöffnet werden muss, wenn der Türantrieb selbst nicht zur Entriegelung und Öffnung der Schachttür 4 betätigbar ist. Ursache kann eine Betriebsstörung der Aufzugsanlage im Falle eines Stromausfalls sein. Entsprechend kann eine Notbefreiung von in der Aufzugskabine 10 befindlichen Personen notwendig sein. Zu diesem Zweck ist der Türriegel 32 mittels eines Schlüssels von einer dem Stockwerk 8 zugewandten Seite der Schachttür 4 aus seiner Verriegeltenstellung in seine Entriegeltenstellung bringbar. Die Schachttür 4 kann demnach stockwerksseitig eine Schlüsselöffnung 37 aufweisen, durch welche Schlüsselöffnung 37 der Türriegel 32 mittels des Schlüssels betätigbar ist. Ein solcher Schlüsse! kann als 1 n nendre i kantsc h I ü se I ausgebildet sein. It is possible that the shaft door 4 must be opened when the door drive itself is not actuated for unlocking and opening the landing door 4. Cause can be a malfunction of the elevator system in case of power failure. Accordingly, an emergency release of persons located in the elevator car 10 may be necessary. For this purpose, the door latch 32 can be brought from its locked position into its unlocked position by means of a key from a side of the shaft door 4 facing the floor 8. The shaft door 4 may therefore have on the floor side a key opening 37, through which keyhole opening 37 of the door latch 32 can be actuated by means of the key. Such conclusions! can be designed as 1 n nthere i kantsc h I ü se I.
Die Notbefreiung von Personen aus der Au fzugskabine 10 ist jedoch nur zulässig, wenn die Aufzugskabine 10 innerhalb einer der Schachttür 4 zugeordneten Notbefreiungszone angeordnet ist. Die Aufzugskabine 10 befindet sich in der Notbefreiungszone der Schachttür 4, wenn Personen bei geöffneter Schachttür 4 nicht aus der Aufzugskabine 10 in den Aufzugsschacht 3 gelangen können. Eine Notbefreiung aus einer ausserhalb der Notbefreiungszone angeordneten Aufzugskabine könnte beispielsweise zu einem Sturz in den Aufzugsschacht führen. Entsprechend ist eine solche N otbefre i u n gs/.one durch maximal zulässige Niveauabwei- chungen SUMAX» SOMAX zwischen dem Kabinenboden 1 1 und dem der Schachttür 4 zugeordneten Stockwerksboden 9 definiert. Dabei kann die maximal nach unten zulässige Niveauabweichung SUMAX, mit der der Kabinenboden 1 1 unterhalb des Stockwerkbodens 9 zulässig anordenbar ist, von einer maximal nach oben zulässigen Niveauabweichung SOMAX, mit der der Kabinenboden 1 1 oberhalb des Stockwerkbodens 9 zulässig anordenbar ist, verschieden sein. The emergency exemption of persons from the Au fab cabin 10 is only permitted if the elevator car 10 is disposed within a shaft door 4 associated emergency exemption zone. The elevator car 10 is located in the emergency exemption zone of the shaft door 4, when persons can not get out of the elevator car 10 into the elevator shaft 3 when the shaft door 4 is open. An emergency rescue from an elevator car arranged outside the emergency relief zone could, for example, lead to a fall into the elevator shaft. Accordingly, such a N otbefre iun gs / .one by maximum permissible deviations Niveauabwei- SUMAX "SOMAX defined between the cab floor 1 1 and the landing door 4 associated landing floor. 9 In this case, the maximum downwardly permissible level deviation SUMAX, with which the cabin floor 1 1 below the floor 9 floor is permissible arrange, from a maximum permissible upward level deviation SOMAX, with the cabin floor 1 1 above the floor 9 floor is permissible be different.
Demnach gilt die Aufzugskabine 10 als innerhalb der Notbefreiungszone angeordnet, wenn der Kabinenboden 1 1 der Aufzugskabine 10 zum Stockwerksboden 9 eine rich- tungsbezogene Niveauabweichung S aufweist, welche Niveauabweichung S kleiner oder gleich der maximal zulässigen Niveauabweichung SUMAX. SOMAX in dieser Richtung ist. Accordingly, the elevator car 10 is considered to be located within the emergency exemption zone when the car floor 1 1 of the elevator car 10 to floor level 9 has a direction-related level deviation S, which level deviation S is less than or equal to the maximum permissible level deviation SUMAX. SOMAX is in this direction.
Eine Notbefreiungslänge 1 1 wird durch eine Addition der maximal nach unten zulässigen Niveauabweichung SUMAX mit der maximal nach oben zulässigen NiveauabweichungAn emergency relief length 1 1 is achieved by adding the maximum downwards permitted level deviation SUMAX with the maximum upward level deviation
SOMAX gebildet. Um diese Notbefreiungslänge H an der Schachttür 4 entlang des Ver- fahrweges der Aufzugskabine 1 0 zu erhöhen, also die Notbefreiungszone zu vergrössern, kann an der Aufzugskabine 10 eine Sicherung, beispielhaft unterhalb des Kabinenbodens 1 1 eine Sicherheitsschürze 14, befestigt sein. SOMAX formed. In order to increase this emergency relief length H at the shaft door 4 along the travel path of the elevator car 1 0, ie to enlarge the emergency relief zone, a safety, for example below the cabin floor 1 1, a safety apron 14 can be attached to the elevator car 10.
Die Figuren 3A, 3B, 4A, 4B zeigen einen Ausschnitt einer gemäss Figur 2 beschriebenen Schachttür 4, an der ein Blockierelement 34 in einer ersten Ausgestaltungsvariante (Figuren 3A, 3B) bzw, ein Blockierelement 34 in einer zweiten Alisgestaltungsvariante (Figuren 3A, 3B) angeordnet werden kann. Die Figuren 3A und 4A zeigen das jeweilige Blockierelement 34 in seiner Blockierstellung, wobei die Figuren 3 B bzw. 4B das entsprechende Blockierelement 34 in seiner Freigabestellung zeigen. Das Blockierelement 34 kann eine Kontaktrolle 42 und/oder ein Rücksteilelement, vorzugsweise eine Rückstellfeder 40 (Figuren 3A, 3B), umfassen. Das Blockierelement 34 kann beispielhaft als Schwenkriegel (Figuren 4A, 4B) oder als Sperrbolzen (Figuren 3A, 3B) ausgebildet sein. FIGS. 3A, 3B, 4A, 4B show a detail of a shaft door 4 described according to FIG. 2, on which a blocking element 34 in a first embodiment variant (FIGS. 3A, 3B) or a blocking element 34 in a second embodiment variant (FIGS. 3A, 3B). can be arranged. FIGS. 3A and 4A show the respective blocking element 34 in its blocking position, with FIGS. 3B and 4B respectively showing the corresponding blocking element 34 in its release position. The blocking element 34 may comprise a contact roller 42 and / or a rear part element, preferably a return spring 40 (FIGS. 3A, 3B). The blocking element 34 can be designed, for example, as a pivot bolt (FIGS. 4A, 4B) or as a locking bolt (FIGS. 3A, 3B).
Die Schachttür 4 weist ein in seiner Geschlossenstellung gezeigtes Türblatt 6 auf. An der Schachttür 4 ist zusätzlich zum B lockierelement 34 ein Türriegel 32 angeordnet. DerThe shaft door 4 has a door leaf 6 shown in its closed position. At the landing door 4, a door latch 32 is arranged in addition to the B 34 lockierelement. Of the
Türriegel 32 ist beispielhaft um eine Schwenkachse 33 schwenkbar ausgebildet. In seiner Verriegeltenstellung greift der Türriegel 32 in einen Riegelanschlag 36, wodurch verhin- dert wird, dass die Schachttür 4 geöffnet werden kann, also das Türblatt 6 eine Öffnungsbewegung O ausführen kann. Beispielhaft kann der Türriegel 32 am Türblatt 6 und der Riegelanschlag 36 an einem Türrahmen der Schachttür 4 oder vice versa angeordnet sein. Ist der Türriegel 32 beispielhaft mitteis eines Schlüssels von einer dem Stockwerk zugewandten Seite der Schachttür 4 aus seiner Verriegeltenstellung (gezeigt in den Figuren 3A, 3B, 4B) in seine Entriegeltenstellung (gezeigt in Figur 4A) überführt, verhindert der Türriegel 32 bzw. der Riegelanschlag 36 die Öffnungsbewegung O des Türblattes 6 nicht. Door latch 32 is formed by way of example about a pivot axis 33 pivotally. In its locked position, the door latch 32 engages in a latch stop 36, which prevents is changed that the shaft door 4 can be opened, so the door panel 6 can perform an opening movement O. By way of example, the door latch 32 can be arranged on the door leaf 6 and the latch stop 36 on a door frame of the landing door 4 or vice versa. If the door bolt 32 is transferred by way of example by means of a key from a floor-facing side of the shaft door 4 from its locked position (shown in FIGS. 3A, 3B, 4B) into its unlocked position (shown in FIG. 4A), the door bolt 32 or the bolt stop prevents it 36, the opening movement O of the door leaf 6 not.
Das Blockierelement 34 ist derart ausgebildet und angeordnet, dass das BlockierelementThe blocking element 34 is designed and arranged such that the blocking element
34 in seiner Blockierstellung eine Öffnungsbewegung O des Türblattes 6 und damit eine Öffnung der Schachttür 4 unabhängig von der Stellung des Türriegels 32 verhindert. 34 in its blocking position prevents an opening movement O of the door leaf 6 and thus an opening of the shaft door 4, regardless of the position of the door bolt 32.
Das Blockierelement 34 ist mittels eines Aktuators 30 aus seiner Blockierstellung in seine Freigabestellung überführbar, beispielhaft mittels einer Bewegung B des Blockierelementes 34. Der Aktuator 30 kann beispielhaft als mechanisch wirkende Führungskurve (Figuren 3A, 3B, 4A, 4B) oder als elektrisches Schaltmittel ausgebildet sein. Ein solcher Aktuator 30 ist vorzugsweise an der Aufzugskabine angeordnet. Ebenso kann der Aktuator durch eine Positionserfassungseinheit zur Erfassung einer Position der Aufzugskabine im Aufzugsschacht gebildet sein. The blocking element 34 can be transferred from its blocking position into its release position by means of an actuator 30, for example by means of a movement B of the blocking element 34. The actuator 30 can be designed, for example, as a mechanically acting guide curve (FIGS. 3A, 3B, 4A, 4B) or as an electrical switching device , Such an actuator 30 is preferably arranged on the elevator car. Likewise, the actuator may be formed by a position detection unit for detecting a position of the elevator car in the elevator shaft.
Der Aktuator 30 wirkt auf das Blockierelement 34 entlang des Bereiches, in dem die rich- tungsbezogene Niveauabweichung S gemäss Figur 2 kleiner oder gleich der maximal zulässigen Niveauabweichungen SUMAx, SQMAX ist. Die gezeigte an der Aufzugskabine angeordnete Führungskurve 30 weist demnach eine Länge entsprechend der "Notbefreiungslänge I I (Figur 2) auf, entlang welcher Länge die Führungskurve 30 auf das Blockierelement 34 wirkt. Entsprechend dieser Wirkung ist das Blockierelement 34 in seiner Freigabestellung, wenn sich die Aufzugskabine in der Notbefreiungszone der Schachttür 4 befindet. Das Blockierelement 34 ist hingegen in seiner Blockierstellung, wenn die Aufzugskabine nicht in der Notbefreiungszone der Schachttür 4 angeordnet ist. Das Rückstellelement 40 bewirkt, dass das Blockierelement 34 seine Blockierstellung einnimmt, sobald die Aufzugskabine ausserhalb der Notbefreiungszone angeordnet ist. Alternativ da/u kann das Blockierelement 34 aus seiner Freigabestellung in seine Blockierstellung und vice versa mittels des Aktuators 30 überführt werden. Das Blockierelement 34 bewirkt somit, dass die Sehachttür 4 in keinem Fall offenbar ist, wenn die Aufzugskabine ausserhalb der Notbefreiungszone dieser Schachttür 4 angeordnet ist. Derart ist es verunmöglicht, dass Personen durch diese Schachttür 4 direkt in den Aufzugsschacht gelangen. The actuator 30 acts on the blocking element 34 along the region in which the direction-related level deviation S according to FIG. 2 is less than or equal to the maximum permissible level deviations S UMA x, SQMAX. The guide curve 30 shown arranged on the elevator car accordingly has a length corresponding to the " emergency rescue length II (Figure 2), along which length the guide curve 30 acts on the blocking element 34. According to this effect, the blocking element 34 is in its release position when the elevator car in the emergency exemption zone of the landing door 4. The blocking element 34, however, is in its blocking position when the elevator car is not located in the emergency exemption zone of the hoistway door 4. The return element 40 causes the blocking element 34 to assume its blocking position as soon as the elevator car is located outside the emergency exemption zone Alternatively, the blocking element 34 can be transferred from its release position into its blocking position and vice versa by means of the actuator 30. The blocking element 34 thus has the effect that the express door 4 is in no case apparent when the elevator cage is arranged outside the emergency release zone of this shaft door 4. In this way it is impossible for persons to pass directly through this landing door 4 into the elevator shaft.
Die ontaktroile 42 des Blockierelementes 34 ermöglicht die mechanische Wechselwirkung zwischen der Führungskurve 30 und dem Blockierelement 34. Mittels der Kontaktrolle 42 kann die Bewegung B des Blockierelementes 34 bzw. ein Halten des Blockierelementes 34 in seiner Freigabestellung beispielhaft realisiert sein. The ontaktroile 42 of the blocking element 34 allows the mechanical interaction between the guide cam 30 and the blocking element 34. By means of the contact roller 42, the movement B of the blocking element 34 and a holding of the blocking element 34 can be realized in its release position by way of example.
Das in den Figuren 3A, 3B gezeigte Blockierelement 34 wirkt auf den Türriegel 32 derart, dass der Türriegel 32 in seiner Verriegeltenstellung blockiert ist, wenn die Aufzugskabine nicht innerhalb der Notbefreiungszone angeordnet ist. Zu diesem Zweck weist der Türriegel 32 ein Sperrmittel 38 auf. Das Sperrmittel 38 verhindert bei einem in seiner gemäss Figur 3A gezeigten Blockierstellung befindlichen Blockierelement 34, dass der Türriegel 32 aus seiner Verriegeltenstellung in seine Entriegeltenstellung bringbar ist. Die entsprechende Bewegung des Türriegels 32, beispielhaft die Schwenkbewegung um seine Schwenkachse 33, wird so verhindert. The blocking member 34 shown in Figures 3A, 3B acts on the door latch 32 such that the door latch 32 is locked in its locked position when the elevator car is not located within the emergency release zone. For this purpose, the door latch 32 has a locking means 38. The blocking means 38 prevents blocking element 34, which is located in its blocking position shown in FIG. 3A, that the door latch 32 can be moved from its locked position into its unlocked position. The corresponding movement of the door bolt 32, for example, the pivoting movement about its pivot axis 33, is prevented.
Ist das Blockierelement 34 gemäss Figur 3B in seiner Freigabestellung, ist der Türriegel 32 nicht durch das Blockierelement 34 in seiner Verriegeltenstellung blockiert. Demnach kann der Türriegel 32 in seiner Verriegelten- oder Entriegeltenstellung angeordnet sein. Bei der Anordnung des Türriegels 32 in seiner Entriegeltenstellung ist die Schachttür 4 offenbar, also das Türblatt 6 aus seiner Geschlossenstellung mittels der Öffnungsbewegung O betätigbar. If the blocking element 34 according to FIG. 3B is in its release position, the door latch 32 is not blocked by the blocking element 34 in its locked position. Accordingly, the door latch 32 may be disposed in its locked or unlocked position. In the arrangement of the door bolt 32 in its unlocked position, the shaft door 4 is obviously, so the door leaf 6 from its closed position by means of the opening movement O actuated.
Das in den Figuren 4A, 4B gezeigte Blockierelement 34 wirkt auf das Tiirblatt 6, so dass das Türblatt 6 in seiner Geschlossenstellung mittels des Blockierelementes 34 blockiert ist, wenn die Aufzugskabine nicht innerhalb der Notbefreiungszone angeordnet ist. Bei einem in Blockierstellung befindlichen Blockierelement 34 ist die Schachttür 6 unabhängig von der Stellung des Türriegels 32 nicht offenbar. Ist das Blockierelement 34 in seiner Freigabestellung angeordnet, ist die Stellung des Türriegels 32 massgebend dafür, ob die Schachttür 4 geöffnet werden kann. Befindest sich der Türriegel 32 in seiner Verriegeltenstellung, ist die Öffnungsbewegung O des Türblattes 6 nicht ermöglicht. Befindet sich der Türriegel 32 in seiner Entriegeltenstellung, ist die Öffnungsbewegung O des Türblattes 6 ausführbar. Wie bereits innerhalb der Beschreibung geschildert, kann der Türriegel 32 mittels des Türantriebes oder mittels des Schlüssels aus seiner Verriegeltenstellung in seine Entriegeltenstellung gebracht werden. The blocking element 34 shown in Figures 4A, 4B acts on the door leaf 6, so that the door leaf 6 is locked in its closed position by means of the blocking element 34, when the elevator car is not disposed within the emergency relief zone. In an in blocking position blocking element 34, the shaft door 6 is not apparent regardless of the position of the door bolt 32. If the blocking element 34 is arranged in its release position, the position of the door bolt 32 determines whether the shaft door 4 can be opened. If the door latch 32 is in its locked position, the opening movement O of the door leaf 6 is not possible. Is located the door latch 32 in its unlocked position, the opening movement O of the door leaf 6 is executable. As already described within the description, the door latch 32 can be brought by means of the door drive or by means of the key from its locked position to its unlocked position.
Beispielhaft ist das Blockierelement 34 mittels Gravitationskraft in seiner Blockierstellung gehalten. Der Aktuator 30 wechselwirkt bei der innerhalb der Notbefreiungszone angeordneten Aufzugskabine mit dem Blockierelement 34 derart, dass das Blockierelement 34 entgegen seiner Gravitationskraft in seine Freigabestellung überführt, vorzugsweise um eine dem Blockierelement 34 zugeordneten an der Schachttür 4 angeordneten Schwenkachse 43 geschwenkt, ist. By way of example, the blocking element 34 is held in its blocking position by means of gravitational force. The actuator 30 interacts with the blocking element 34 arranged in the emergency release zone in such a way that the blocking element 34 is transferred against its gravitational force into its release position, preferably pivoted about a pivot axis 43 assigned to the blocking element 34 and arranged on the shaft door 4.
Figur 5 zeigt einen Aufzugsschacht 3 einer Aufzugsanlage 2. Der Aufzugsschacht 3 um- fasst eine Schachtgrube 7 und einen Schachtkopf 5. In dem Aufzugsschacht 3 ist eine Aufzugskabine 10 an einer untersten der Schachttüren 4. 1 , 4.2, 4.3 und damit im Wesentlichen unmittelbar über der Schachtgrube 7 angeordnet. Die Aufzugskabine 10 weist einen Kabinenboden 1 1 mit einer Bodenklappe 12 auf. Die Bodenklappe 12 ist in ihrer Offenstellung gezeigt. Die Bodenklappe 12 in ihrer Geschlossenstellung hat die Funktion eines herkömmlichen Kabinenbodens 1 1 . An der untersten Schachttür 4.1 ist sowohl der Türriegel als auch das Blockierelement gemäss der Beschreibung zu den Figuren 3A, 3B, 4A, 4B angeordnet. Der auf das Blockierelement wirkende Aktuator 30 ist beispielhaft an der Aufzugskabine 10 angeordnet. FIG. 5 shows an elevator shaft 3 of an elevator installation 2. The elevator shaft 3 comprises a shaft pit 7 and a shaft head 5. In the elevator shaft 3, an elevator cage 10 is at a bottom of the shaft doors 4. 1, 4.2, 4.3 and thus substantially directly over the shaft pit 7 is arranged. The elevator car 10 has a cabin floor 1 1 with a bottom flap 12. The bottom flap 12 is shown in its open position. The bottom flap 12 in its closed position has the function of a conventional cabin floor 1 1. At the bottom landing door 4.1 both the door latch and the blocking element according to the description of Figures 3A, 3B, 4A, 4B is arranged. The actuator 30 acting on the blocking element is arranged on the elevator car 10 by way of example.
Die Abmessungen der gezeigten Schachtgrube 7 sind insbesondere hinsichtlich ihrer Höhe so gering, dass kein Schutzraum 16 für Personen ausserhalb der Aufzugskabine 10 in der Schachtgrube 7 angeordnet sein kann. Um befugten Personen wie Servicepersonal trotz der beschriebenen Wirkung des Blockierelementes das Ausführen von Arbeiten (Wartung oder Reinigung) in der Schachtgrube 7 zu ermöglichen, ist die Schachtgrube 7 bei geöffneter Bodenklappe 12 aus der Aufzugskabine 10 erreich- bzw. betretbar. Beispielhaft ist diese Bodenklappe 12 nur offenbar bzw. entriegelbar, wenn die Aufzugskabine 10 unmittelbar an der Schachtgrube 7 oder unwesentlich darüber angeordnet ist, so dass kein gefährlicher Absturz aus der Aufzugskabine 10 bei geöffneter Bodenklappe 12 in die Schachtgrabe 7 riskiert ist. Der Schutzraum 16 kann sich bei geöffneter Bodenklappe 12 in d ie Aufzugskabine 1 0 erstrecken. Die Aufzugsanlage ist demnach derart ausgebildet, dass sichergestellt ist, dass sich die zuvor bei geöffneter Bodenklappe 12 in der Schachtgrube 7 befindliche Person im Innenraum der Aufzugskabine 10 befinden muss, um die Bodenklappe 12 zu ver- schliessen. Beispielhaft kann zu diesem Zweck eine Bodenk iappe 12 vorgesehen werden, welche nur aus dem Kabineninnenraum ent- bzw. verriegeibar ist, wobei die Aufzugskabine 10 im Aufzugsschacht 3 nur bei verriegelter Bodenklappe 12 verfahrbar ist. The dimensions of the shaft pit 7 shown are so small, in particular with regard to their height, that no shelter 16 for persons outside the elevator car 10 can be arranged in the shaft pit 7. In order to allow authorized persons such as service personnel despite the described effect of the blocking element to perform work (maintenance or cleaning) in the pit 7, the pit 7 with open bottom flap 12 from the elevator car 10 can be reached or entered. By way of example, this bottom flap 12 is only apparent or unlockable when the elevator car 10 is located directly on the shaft pit 7 or insignificantly above it, so that no dangerous crash from the elevator car 10 is risked in open pit bottom 12 in the pit trench 7. The shelter 16 may extend into the elevator car 10 when the bottom flap 12 is open. Accordingly, the elevator installation is designed in such a way that it is ensured that the person previously in the shaft pit 7 when the bottom flap 12 is open must be located in the interior of the elevator car 10 in order to close the bottom flap 12. By way of example, a Bodenk iappe 12 can be provided for this purpose, which is entriegeibar only from the cabin interior, wherein the elevator car 10 in the elevator shaft 3 is movable only when the bottom flap 12 is locked.
Zusätzlich oder alternativ zu einer Anordnung des beschriebenen Blockierelementes an der untersten Schachttür 4.1 kann jeweils ein solches Blockierelement an zumindest einer der darüber angeordneten Schachttüren 4.2, 4.3 angeordnet sein. In addition or as an alternative to an arrangement of the described blocking element on the lowermost shaft door 4.1, in each case such a blocking element can be arranged on at least one of the shaft doors 4.2, 4.3 arranged above it.
Bei derart verringerten Abmessungen der Schachtgrube 7 kann der Schachtkopf 5 des Aufzugsschachtes 3 genügend gross bemessen sein, dass ein Schutzraum 16 ausserhalb der Aufzugskabine 10 im Schachtkopf 5 anordenbar ist. Entsprechend darf Servicepersonal durch eine der geöffneten Schachttüren 4.1 , 4.2, 4.3 auf die Aufzugskabine 10 gelangen, wobei aber gleichzeitig sicherzustellen ist, dass das Servicepersonal nicht unterhalb der Aufzugskabine 10 durch eine der geöffneten Schachttüren 4.1 , 4.2, 4.3 in die Schachtgrube 7 gelangen kann. Entsprechend können beispielhaft zusätzlich zur Anordnung des Türriegels und des Blockierelementes an der untersten Schachttür 4.1 alle weiteren Schachttüren 4.2, 4.3 ausgenommen einer obersten der Schachttüren 4.1 , 4.2, 4.3 mit jeweils einem solchen Türriegel und jeweils einem solchen Blockierelement gemäss der Beschreibung zu den Figuren 3A, 3B, 4A, 4B oder mit einer alternativen Sicherheitseinrichtungen versehen sein. Mittels einer solchen alternativen Sicherheitseinrichtung ist sicherzustellen, dass ein Öffnen einer zwischen der obersten Schachttür 4.3 und der untersten Schachttür 4. 1 angeordneten mittleren Schachttür 4.2 verunmöglicht ist, wenn die Aufzugskabine 10 nicht in der Notbefreiungszone dieser mittleren Schachttür 4.2 angeordnet ist. With such reduced dimensions of the shaft pit 7, the shaft head 5 of the elevator shaft 3 can be sized sufficiently large that a shelter 16 outside the elevator car 10 in the shaft head 5 can be arranged. Accordingly, service personnel may pass through one of the open landing doors 4.1, 4.2, 4.3 to the elevator car 10, but at the same time ensure that the service personnel can not get below the elevator car 10 through one of the open shaft doors 4.1, 4.2, 4.3 in the pit 7. Accordingly, by way of example, in addition to the arrangement of the door bolt and the blocking element at the bottom landing door 4.1 all other shaft doors 4.2, 4.3 except a top of the shaft doors 4.1, 4.2, 4.3, each with such a door latch and each such blocking element according to the description of Figures 3A, 3B, 4A, 4B or be provided with an alternative safety devices. By means of such an alternative safety device, it is to be ensured that it is impossible to open a central shaft door 4.2 arranged between the uppermost shaft door 4.3 and the lowermost shaft door 4. 1 if the elevator car 10 is not arranged in the emergency rescue zone of this central shaft door 4.2.
Bei verringerten Abmessungen sowohl der Schachtgrube 7 als auch des Schachtkopfes 5 kann jeweils ein solcher Türriegel und jeweils ein solches Blockierelement an jeder der Schachttüren 4. 1 , 4.2, 4.3 angeordnet sein. With reduced dimensions of both the shaft pit 7 and the shaft head 5 can be arranged on each of the shaft doors 4. 1, 4.2, 4.3 each such a door latch and each such blocking element.
Alternativ zur gezeigten Darstellung ist es möglich, dass zur Anordnung von Schutzräu- men 16 ausserhalb der Aufzugskabine 10 die Schachtgrube 7 genügend gross bemessen und der Schachtkopf 5 zu klein bemessen ist. Entsprechend können beispielhaft alle mit Ausnahme der untersten der Schachttüren 4.1, 4.2, 4.3 mit jeweils einem solchen Türriegel und jeweils einem solchen Blockierelement gemäss der Beschreibung zu den Figuren 3A, 3B, 4A, 4B versehen sein. Derart kann Servicepersonal durch die unterste derAs an alternative to the illustration shown, it is possible for the arrangement of protective men 16 outside the elevator car 10, the pit 7 sized large enough and the shaft head 5 is too small. Correspondingly, by way of example, all but the lowermost of the shaft doors 4.1, 4.2, 4.3 can be provided with one such door latch and one respective blocking element according to the description of FIGS. 3A, 3B, 4A, 4B. Thus, service personnel can by the lowest of the
Schachttüren 4.1 direkt in die Schachtgrube 7 gelangen, Jedoch ist verhindert, dass das Servicepersonal durch eine der Schachttüren 4.1 , 4,2, 4.3 direkt auf die Aufzugskabine 10 gelangen kann. Entsprechend der gezeigten Bodenklappe 12 kann die Aufzugskabine 10 eine Dachklappe zur Wartung des Schachtkopfes 5 aufweisen. Manhole doors 4.1 enter directly into the pit 7, However, it is prevented that the service personnel through one of the shaft doors 4.1, 4.2, 4.3 can get directly to the elevator car 10. According to the bottom flap 12 shown, the elevator car 10 may have a roof flap for the maintenance of the shaft head 5.
