Diese Aufgabe wird durch eine Aufzugsanlage mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.This object is achieved by an elevator installation with the features of claim 1. Advantageous embodiments and modifications of the invention are the subject of the dependent claims.

Dabei sind an jeder der Kabinen des Mehrdeckfahrzeugs Führungselemente angebracht, die die jeweils zugeordnete Kabine an den Führungsschienen führen.Multi-deck vehicle with the aid of a drive and a support means along guide rails is movable. In this case, guide elements are attached to each of the cabins of the multi-deck vehicle, which guide the respectively assigned cab to the guide rails.

Im Gegensatz zu den herkömmlichen Aufzugsanlagen mit einem Mehrdeckfahrzeug ist bei dem Mehrdeckfahrzeug der erfindungsgemässen Aufzugsanlage kein gemeinsamer Kabinenrahmen vorgesehen, sondern die einzelnen Kabinen des Mehrdeckfahrzeugs sind in ihrer wenigstens einen Führungsebene jeweils direkt an den Führungsschienen der Aufzugsanlage geführt. Die Gesamtkonstruktion eines solchen Mehrdeckfahrzeugs hat ein geringeres Gewicht und ist einfacher herstellbar sowie einfacher installierbar. Ausserdem besitzt das erfindungsgemässe Mehrdeckfahrzeug ein verbessertes Schwingungsverhalten, da im Gegensatz zu den herkömmlichen Aufzugsanlagen mit einem ersten Bewegungssystemen zwischen Kabinen und Kabinenrahmen und einem zweiten Bewegungssystemen zwischen Kabinenrahmen und Führungsschienen, nur noch ein einziges Bewegungssystem zwischen den Kabinen und den Führungsschienen vorhanden ist und eine Schwingungskopplung zwischen den einzelnen Kabinen über den gemeinsamen Kabinenrahmen entfällt. Ausserdem entfällt die in Bezug auf das Schwingungsverhalten nachteilige, grosse und schwere Zusatzkomponente des gemeinsamen Kabinenrahmens.In contrast to the conventional elevator systems with a multi-deck vehicle, no common cabin frame is provided in the multi-deck vehicle of the elevator system according to the invention, but the individual cars of the multi-deck vehicle are each guided directly on the guide rails of the elevator installation in their at least one guide level. The overall construction of such a multi-deck vehicle has a lower weight and is easier to produce and easier to install. In addition, the multi-deck vehicle according to the invention has an improved vibration behavior, since in contrast to the conventional elevator systems with a first movement systems between cabins and car frame and a second movement systems between cabin frame and guide rails, only a single movement system between the cabs and the guide rails is present and a vibration coupling between the individual cabins on the common cabin frame deleted. In addition, eliminates the adverse in relation to the vibration behavior, large and heavy additional component of the common cabin frame.

Eine solche Kopplungsvorrichtung dient dazu, die Trag- und Antriebskräfte von jeweils einer der Kabinen des Mehrdeckfahrzeugs zur benachbarten Kabine so zu übertragen.Advantageously, the at least two cabins of the multi-deck vehicle are connected to one another by a coupling device which is designed in such a way that forces directed between the cabs can be transmitted by the coupling device exclusively essentially parallel to the longitudinal axes of the guide rails. Such a coupling device serves to transmit the carrying and driving forces of one of the cabins of the multi-deck vehicle to the adjacent cabin in this way.

The advantage lies in the fact that a statically determined state of the cabin guidance is given at any time for each car. There are no undefined leadership conditions, as is the case with multi-deck vehicles, which have a rigid common cabin frame, which is guided in more than two management levels.

Vorzugsweise ist wenigstens eine der Kabinen des Mehrdeckfahrzeugs in wenigstens zwei in Bewegungsrichtung des Mehrdeckfahrzeugs voneinander beabstandeten Führungsebenen mit Führungselementen versehen, die die Kabine in diesen Führungsebenen unabhängig von Führungselementen weiterer Führungsebenen des Mehrdeckfahrzeugs an den Führungsschienen führen.Preferably, at least one of the cabins of the multi-deck vehicle is provided with guide elements in at least two guide planes which are spaced apart from one another in the direction of movement of the multi-deck vehicle and guide the cab in these guide planes independently of guide elements of further guide levels of the multi-deck vehicle to the guide rails.

Bei einer solchen Ausführungsform ist wenigstens eine der Kabinen statisch vollständig bestimmt und unabhängig von weiteren Kabinen des Mehrdeckfahrzeugs an den Führungsschienen geführt.In such an embodiment, at least one of the cabins is statically completely determined and guided independently of other cabins of the multi-deck vehicle on the guide rails.

Unter dem Begriff "Bewegungsrichtung des Mehrdeckfahrzeugs" ist im vorliegenden Zusammenhang eine Bewegungsrichtung des Mehrdeckfahrzeugs in Richtung der Längsachse der Führungsschienen zu verstehen.The term "direction of movement of the multi-deck vehicle" in the present context means a direction of movement of the multi-deck vehicle in the direction of the longitudinal axis of the guide rails.

In einer alternativen Ausgestaltung ist wenigstens eine der Kabinen des Mehrdeckfahrzeugs in wenigstens zwei in Bewegungsrichtung des Mehrdeckfahrzeugs voneinander beabstandeten Führungsebenen mit Führungselementen versehen, die die Kabine in diesen Führungsebenen unabhängig von Führungselementen weiterer Führungsebenen des Mehrdeckfahrzeugs an den Führungsschienen führen. Wenigstens eine weitere der Kabinen des Mehrdeckfahrzeugs ist dabei in einer ersten Führungsebene an einer benachbarten Kabine des Mehrdeckfahrzeugs geführt und in einer in Bewegungsrichtung des Mehrdeckfahrzeugs von der ersten Führungsebene beabstandeten zweiten Führungsebene mit Führungselementen versehen, die die weitere Kabine in ihrer zweiten Führungsebene unabhängig von Führungselementen weiterer Führungsebenen des Mehrdeckfahrzeugs an den Führungsschienen führen. Der Vorteil einer solchen Ausführungsform liegt darin, dass bei den weiteren Kabinen jeweils auf einen Satz Führungselemente verzichtet werden kann.In an alternative embodiment, at least one of the cabins of the multi-deck vehicle is provided with guide elements in at least two guide planes spaced from one another in the direction of movement of the multi-deck vehicle, which guides the cab in these guide planes independently of guide elements of further guide planes of the multi-deck vehicle to the guide rails. At least one more of the cabins of the multi-deck vehicle is guided in a first management level on an adjacent cabin of Mehrdeckfahrzeugs and provided in a direction of movement of the multi-deck vehicle from the first management level spaced second management level with guide elements, the further cabin in its second management level independent of guide elements further Guide levels of the multi-deck vehicle on the guide rails. The advantage of such an embodiment is that in the other cabins can be dispensed with a set of guide elements.

Vorteilhafterweise umfasst die Kopplungsvorrichtung wenigstens ein Gelenk, über welches sie mit wenigstens einer der Kabinen des Mehrdeckfahrzeugs gelenkig verbunden ist. Mit einem solchen Gelenk bzw. einer solchen gelenkigen Verbindung wird erreicht, dass die Kopplungsvorrichtung bei der Übertragung der Trag- und Antriebskräfte von jeweils einer der Kabinen des Mehrdeckfahrzeugs zur benachbarten Kabine nur Kräfte überträgt, die im Wesentlichen in Bewegungsrichtung des Mehrdeckfahrzeugs, d. h. in Richtung der Längsachse der Führungsschienen gerichtet sind.Advantageously, the coupling device comprises at least one joint, via which it is articulated to at least one of the cabins of the multi-deck vehicle. With such a joint or such an articulated connection is achieved that the coupling device transmits only forces in the transmission of the supporting and driving forces of one of the cabins of the multi-deck vehicle to the adjacent cabin, which essentially in the direction of movement of the multi-deck vehicle, d. H. directed in the direction of the longitudinal axis of the guide rails.

Gemäss einer der Ausführungsformen der Erfindung ist die Kopplungsvorrichtung auf einer ersten Seite gelenkig mit der einen Kabine und auf einer zweiten Seite starr mit der benachbarten weiteren Kabine verbunden. Dadurch wird ermöglicht, eine Führungsebene der einen Kabine mit Hilfe der Kopplungsvorrichtung mit einer benachbarten Kabine zu verbinden und damit zu führen.According to one embodiment of the invention, the coupling device is pivotally connected on one side to the one cabin and on the other side to the adjacent further cabin. This makes it possible to connect a leadership level of a cabin using the coupling device with an adjacent cabin and to lead.

Vorteilhafterweise ist der Abstand zwischen zwei Kabinen des Mehrdeckfahrzeugs in Bewegungsrichtung des Mehrdeckfahrzeugs mittels einer in der Kopplungsvorrichtung integrierten, motorbetriebenen und steuerbaren Verstelleinrichtung einstellbar.Advantageously, the distance between two cabins of the multi-deck vehicle in the direction of movement of the multi-deck vehicle can be adjusted by means of a motor-operated and controllable adjusting device integrated in the coupling device.

Eine solche Verstelleinrichtung ermöglicht die automatische Anpassung des Abstands zwischen den Bodenniveaus der Kabinen eines Mehrdeckfahrzeugs an unterschiedliche Stockwerksabstände eines Gebäudes.Such an adjustment device allows the automatic adjustment of the distance between the floor levels of the cabins of a multi-deck vehicle to different floor distances of a building.

Gemäss einer weiteren Ausführungsform der erfindungsgemässen Aufzugsanlage weist wenigstens eine der Kabinen des Mehrdeckfahrzeugs einen wenigstens in einem Teilbereich in Bewegungsrichtung des Mehrdeckfahrzeugs verstellbaren Kabinenboden auf, wobei eine Verstellbewegung durch eine motorisch betriebene und steuerbare Verstelleinrichtung erfolgt. Auch mit dieser Ausführungsform wird die automatische Einstellung des Abstands zwischen den Bodenniveaus der Kabinen eines Mehrdeckfahrzeugs auf unterschiedliche Stockwerksabstände eines Gebäudes ermöglicht.According to a further embodiment of the elevator installation according to the invention, at least one of the cabins of the multi-deck vehicle has a cabin floor which is adjustable at least in a partial area in the direction of movement of the multi-deck vehicle, wherein an adjustment movement takes place by means of a motor-driven and controllable adjustment device. Also with this embodiment, the automatic adjustment of the distance between the floor levels of the cabins of a multi-deck vehicle to different floor spacings of a building is made possible.

Vorteilhafterweise umfasst wenigstens eine der Kabinen des Mehrdeckfahrzeugs einen nur dieser Kabine zugeordneten Fangrahmen, in dem ein Kabinenkörper gelagert ist, wobei die dieser Kabine zugeordneten Führungselemente an diesem Fangrahmen fixiert sind.Advantageously, at least one of the cabins of the multi-deck vehicle comprises a catch frame associated only with this cabin, in which a cabin body is mounted, wherein the guide elements assigned to this cabin are fixed to this catch frame.

Der Einbau einer Kabine in einen separaten Fangrahmen ermöglicht die Verwendung von nicht selbsttragenden Kabinenkörpern mit entsprechend geringerer Eigenstabilität und reduziertem Gewicht.The installation of a cabin in a separate catch frame allows the use of non-self-supporting cabins with correspondingly lower intrinsic stability and reduced weight.

Gemäss einer alternativen Ausführungsform ist wenigstens eine der Kabinen des Mehrdeckfahrzeugs als selbsttragende Konstruktion ausgeführt, wobei die dieser Kabine zugeordneten Führungselemente an der selbsttragenden Konstruktion befestigt sind. Mit der Verwendung von selbsttragenden Kabinen ergeben sich eine Vereinfachung der Kabinenkonstruktion sowie eine Reduktion des durch die Kabinen beanspruchten Querschnitts des Aufzugsschachts.According to an alternative embodiment, at least one of the cabins of the multi-deck vehicle is designed as a self-supporting construction, wherein the guide elements associated with this cab are fastened to the self-supporting construction. With the use of self-supporting cabins results in a simplification of the cabin design and a reduction of claimed by the cabins cross-section of the elevator shaft.

Gemäss einem weiteren Aspekt der Erfindung ist wenigstens eine der Kabinen des Mehrdeckfahrzeugs mit wenigstens einer Fangvorrichtung versehen.According to a further aspect of the invention, at least one of the cabins of the multi-deck vehicle is provided with at least one safety gear.

Vorzugsweise ist jede der Kabinen des Mehrdeckfahrzeugs mit wenigstens einer Fangvorrichtung versehen. In diesem Fall können die einzelnen Fangvorrichtungen einfacher aufgebaut sein, da an sie reduzierte Anforderungen gestellt sind, weil die Sicherungsfunktion auf mehrere Fangvorrichtungen verteilt ist.Preferably, each of the cabins of the multi-deck vehicle is provided with at least one safety gear. In this case, the individual safety gears be simpler, because they are reduced requirements, because the backup function is distributed over several safety gears.

Vorteilhafterweise ist das wenigstens eine Tragmittel so angeordnet, dass es unmittelbar eine oberste oder eine unterste Kabine des Mehrdeckfahrzeugs trägt und antreibt, wobei die wenigstens eine weitere Kabine des Mehrdeckfahrzeugs mittels der Kopplungsvorrichtung an die durch das Tragmittel getragene Kabine gekoppelt ist.Advantageously, the at least one suspension element is arranged such that it directly supports and drives a topmost or a bottommost cabin of the multi-deck vehicle, wherein the at least one further cabin of the multi-deck vehicle is coupled by means of the coupling device to the car carried by the suspension element.

Eine Aufzugsanlage gemäss der vorliegenden Erfindung kann als Personenaufzug zum Befördern von Personen und ggf. auch Gütern oder als Güteraufzug, ausschliesslich zum Befördern von Gütern, ausgeführt sein. Des Weiteren ist die erfindungsgemässe Aufzugsanlage in verschiedenen Objekten wie überirdischen und/oder unterirdischen Gebäuden, in Bergwerken oder in Land- oder Wasserfahrzeugen einsetzbar.An elevator installation according to the present invention can be designed as a passenger elevator for transporting persons and possibly also goods or as goods lift, exclusively for transporting goods. Furthermore, the elevator installation according to the invention can be used in various objects such as above-ground and / or underground buildings, in mines or in land or water vehicles.

Die in Fig. 1 gezeigte Aufzugsanlage umfasst ein Mehrdeckfahrzeug 10 mit zwei Kabinen 12, 14, das zwischen - nicht dargestellten - festen Zugangsstellen (insbesondere zwischen Stockwerken eines Gebäudes) entlang einer Fahrbahn bewegbar ist. Das Mehrdeckfahrzeug 10 umfasst eine obere Kabine 12 und eine untere Kabine 14. Im Rahmen der vorliegenden Erfindung können Mehrdeckfahrzeuge aber auch mehr als zwei Kabinen umfassen, und die folgenden Erläuterungen sind auch auf solche Mehrdeckfahrzeuge anwendbar.In the Fig. 1 elevator system shown comprises a multi-deck vehicle 10 with two cabins 12, 14, which between - not shown - fixed access points (especially between floors of a building) along a roadway is movable. The multi-deck vehicle 10 comprises an upper cabin 12 and a lower cabin 14. In the context of the present invention, however, multi-deck vehicles can also do more as two cabins, and the following explanations are also applicable to such multi-deck vehicles.

Die Kabinen 12, 14 des Mehrdeckfahrzeugs 10 gemäss Fig. 1 sind vertikal übereinander angeordnet und werden in vertikaler Richtung bewegt. Im Rahmen der vorliegenden Erfindung kann das Mehrdeckfahrzeug 10 aber auch in geneigten Fahrbahnen, entlang einer gekrümmten Kurvenbahn oder in einer Kombination der genannten Möglichkeiten bewegbar konzipiert sein.The cabins 12, 14 of the multi-deck vehicle 10 according Fig. 1 are vertically stacked and moved in the vertical direction. In the context of the present invention, however, the multi-deck vehicle 10 can also be designed to be movable in inclined roadways, along a curved curved path or in a combination of the named possibilities.

Das Mehrdeckfahrzeug 10 ist mit Hilfe eines Tragmittels 16 entlang seiner durch Führungsschienen 20 bestimmten Fahrbahn bewegbar. Das Tragmittel 16 wirkt mit einem Antrieb 18 zusammen, der das Tragmittel und damit das Mehrdeckfahrzeug 10 trägt und antreibt. Als Tragmittel 16 wird vorzugsweise ein biegeelastisches, riemenartiges oder seilartiges Tragmittel verwendet, wobei die Erfindung nicht auf eine spezielle Ausführungsform des Tragmittels beschränkt sein soll. Bei der in Fig. 1 dargestellten Ausführungsform ist ein Ende des Tragmittels 16 mittelbar oder unmittelbar im Bereich der Kabinendecke der obersten Kabine 12 des Mehrdeckfahrzeugs 10 an dieser obersten Kabine befestigt.The multi-deck vehicle 10 is movable with the aid of a suspension element 16 along its track defined by guide rails 20. The support means 16 cooperates with a drive 18, which carries and drives the support means and thus the multi-deck vehicle 10. As a support means 16 is preferably a flexurally elastic, belt-like or rope-like support means is used, the invention should not be limited to a specific embodiment of the support means. At the in Fig. 1 1, one end of the suspension element 16 is attached directly or indirectly in the area of the cabin ceiling of the uppermost cabin 12 of the multi-deck vehicle 10 to this uppermost cabin.

Der Antrieb 18 weist eine Antriebsmaschine oder mehrere ggf. voneinander unabhängig betreibbare Antriebsmaschinen auf, die das Tragmittel bzw. das Mehrdeckfahrzeug 10 über eine Treibscheibe oder eine Trommel antreiben. Die vorliegende Erfindung soll aber auf keine spezielle Ausführungsart des Antriebs 18 beschränkt sein.The drive 18 has a drive machine or a plurality of optionally independently operable drive machines, which drive the support means or the multi-deck vehicle 10 via a traction sheave or a drum. However, the present invention should not be limited to any particular embodiment of the drive 18.

Die Kabinen 12, 14 des in Fig. 1 dargestellten Mehrdeckfahrzeugs 10 umfassen jeweils einen Fangrahmen 12.1, 14.1 der vorzugsweise als Stahlrahmen ausgeführt ist. In diese Fangrahmen sind so genannte Kabinenkörper 12.2, 14.2 integriert, die zur Aufnahme von Passagieren oder Gütern dienen und geeignete Boden-, Wand- und Deckenbauelemente umfassen. Die Kabinenkörper werden im Allgemeinen mit rechteckiger oder quadratischer Grundfläche hergestellt, es sind aber auch andere Kabinenformen möglich, beispielsweise solche mit runder oder sechseckiger Grundfläche. An jeder Kabine 12, 14 ist wenigstens ein Zugang vorgesehen, der in den meisten Fällen mit einer entsprechenden Kabinentür verschliessbar ist. Über solche Zugänge können die Kabinen von den Zugangsstellen der Stockwerke aus betreten bzw. beladen werden. Die vorliegende Erfindung ist bezüglich des Aufbaus der einzelnen Kabinen 12, 14 nicht auf spezielle Ausführungsformen beschränkt.The cabins 12, 14 of in Fig. 1 illustrated multi-deck vehicle 10 each comprise a catch frame 12.1, 14.1 is preferably designed as a steel frame. In this catch frame so-called cabin body 12.2, 14.2 are integrated, which serve to accommodate passengers or goods and include suitable floor, wall and ceiling components. The cabin bodies are generally made with a rectangular or square base, but other cabin shapes are possible, such as those with a round or hexagonal base. At each cabin 12, 14 is provided at least one access, which in in most cases can be closed with a corresponding cabin door. The cabins can be accessed or loaded from the access points of the floors via such accesses. The present invention is not limited to specific embodiments with respect to the structure of the individual cars 12, 14.

Das Mehrdeckfahrzeug 10 ist vorzugsweise, jedoch nicht zwingend in einem Aufzugsschacht mit einer den Schacht zumindest abschnittsweise umgebenden Wand angeordnet. In einer besonders bevorzugten Ausführungsform befindet sich in dem Aufzugsschacht neben der Fahrbahn des Mehrdeckfahrzeugs 10 auch die Fahrbahn eines Gegengewichts. In einer anderen Ausführungsform ist das Gegengewicht in einem separaten Aufzugsschacht untergebracht. Zum Aufzugsschacht gehören im Allgemeinen auch ein Schachtkopf im oberen Endbereich und eine Schachtgrube im unteren Endbereich, um eventuell gewünschte Überfahrwege und Schutzräume bereitzustellen. In der Schachtgrube können zum Beispiel Puffer für das Mehrdeckfahrzeug 10 bzw. das Gegengewicht angeordnet sein.The multi-deck vehicle 10 is preferably, but not necessarily, arranged in an elevator shaft with a wall at least partially surrounding the shaft. In a particularly preferred embodiment, the carriageway of a counterweight is located next to the carriageway of the multi-deck vehicle 10 in the elevator shaft. In another embodiment, the counterweight is housed in a separate elevator shaft. The elevator shaft generally also includes a shaft head in the upper end region and a shaft pit in the lower end region in order to provide any desired transit routes and protective areas. For example, buffers for the multi-deck vehicle 10 or the counterweight can be arranged in the shaft pit.

An den Seitenwänden des Aufzugsschachts sind im Wesentlichen starre Führungsschienen 20 für das Mehrdeckfahrzeug 10 und ggf. auch Führungsschienen für das Gegengewicht angeordnet. Die Führungsschienen 20 haben die Aufgabe, das Mehrdeckfahrzeug 10 in der ihm zugewiesenen Fahrbahn sicher und exakt zu führen. Die Kabinen 12, 14 des Mehrdeckfahrzeugs 10 sind jeweils mit fest an den Kabinen bzw. deren Fangrahmen 12.1 fixierten Führungselementen 22 ausgestattet, mit denen sie an den Führungsschienen 20 im Aufzugsschacht geführt werden. Diese Führungselemente 22 können beispielsweise in Form von Rollenführungsschuhen, Gleitführungsschuhen, Magnetführungsschuhen, etc. vorhanden sein. Gruppen solcher Führungselemente 22 sind jeweils in einer gemeinsamen, sich rechtwinklig zu den Längsachsen der Führungsschienen erstreckenden, im vorliegenden Ausführungsbeispiel horizontalen Führungsebenen 12A, 12B, 14A, 14B an den Kabinen 12, 14 angeordnet. In jeder Führungsebene sind die Kabinen 12, 14 ausschliesslich durch die dieser Führungsebene zugeordneten Führungselemente 22 an den Führungsschienen 20 geführt.On the side walls of the hoistway substantially rigid guide rails 20 are arranged for the multi-deck vehicle 10 and possibly also guide rails for the counterweight. The guide rails 20 have the task to guide the multi-deck vehicle 10 safely and accurately in the assigned roadway. The cabins 12, 14 of the multi-deck vehicle 10 are each equipped with fixed to the cabs and their catch frame 12.1 fixed guide elements 22, with which they are guided on the guide rails 20 in the elevator shaft. These guide elements 22 may be present, for example, in the form of roller guide shoes, Gleitführungsschuhen, magnetic guide shoes, etc. Groups of such guide elements 22 are each arranged in a common, at right angles to the longitudinal axes of the guide rails extending, in the present embodiment horizontal guide planes 12A, 12B, 14A, 14B to the cabins 12, 14. In each management level, the cabins 12, 14 are guided exclusively by the guiding elements 22 assigned to this guide plane to the guide rails 20.

Bei der in Fig. 1 gezeigten Ausführungsform ist jede der beiden Kabinen 12, 14 in zwei in Bewegungsrichtung des Mehrdeckfahrzeugs 10 voneinander beabstandeten Führungsebenen 12A, 12B bzw. 14A, 14B mit Führungselementen 22 ausgerüstet, die die Kabinen in den genannten Führungsebenen unabhängig von in weiteren Führungsebenen des Mehrdeckfahrzeugs 10 vorhandenen Führungselementen an den Führungsschienen 20 führen. Jede der Kabinen 12, 14 ist in ihren beiden Führungsebenen 12A, 12B bzw. 14A, 14B durch die diesen Führungsebenen zugeordneten Führungselemente 22 statisch bestimmt geführt. Undefinierte bzw. unbestimmte Führungszustände und störende Querschwingungen, wie sie bei Mehrdeckfahrzeugen auftreten, die einen starren gemeinsamen Kabinenrahmen mit mehr als zwei Führungsebenen aufweisen, werden bei einer erfindungsgemässen Aufzugsanlage vermieden.At the in Fig. 1 In the embodiment shown, each of the two cabins 12, 14 is equipped with guide elements 22 in two guide planes 12A, 12B and 14A, 14B spaced from one another in the direction of movement of the multi-deck vehicle 10, which guides the cabs independently of guide elements of the multi-deck vehicle 10 in said guide planes lead to the guide rails 20. Each of the cabins 12, 14 is statically guided in its two guide planes 12A, 12B and 14A, 14B by the guide elements 22 assigned to these guide planes. Undefined or indefinite guide states and disturbing transverse vibrations, as they occur in multi-deck vehicles, which have a rigid common cabin frame with more than two guide levels are avoided in an elevator system according to the invention.

Bei dem Ausführungsbeispiel gemäss Fig. 1 sind die beiden Kabinen 12, 14 des Mehrdeckfahrzeugs 10 über eine Kopplungsvorrichtung 24 miteinander verbunden. Beide zwischen der Kopplungsvorrichtung 24 und den beiden Kabinen 12, 14 vorhandenen Kopplungsstellen 24.1 sind als Gelenkkopplung ausgeführt, die vorzugsweise ein Kugelgelenk oder ein Kreuzgelenk umfassen. Dadurch ist gewährleistet, dass die Kopplungsvorrichtung Kräfte nur in Bewegungsrichtung des Mehrdeckfahrzeugs 10 überträgt, so dass die Führungselemente der ersten Kabine und die Führungselemente der zweiten Kabine sich nicht gegenseitig beeinflussen, bzw. dass beide Kabinen 12, 14 effektiv unabhängig voneinander geführt sind.In the embodiment according to Fig. 1 the two cabins 12, 14 of the multi-deck vehicle 10 are connected to one another via a coupling device 24. Both existing between the coupling device 24 and the two cabins 12, 14 coupling points 24.1 are designed as a joint coupling, which preferably comprise a ball joint or a universal joint. This ensures that the coupling device transmits forces only in the direction of movement of the multi-deck vehicle 10, so that the guide elements of the first car and the guide elements of the second car do not influence each other, or that both cabins 12, 14 are effectively guided independently.

Gemäss einer bevorzugten Ausführungsform der Erfindung, ist die Kopplungsvorrichtung 24 so konzipiert, dass sie eine motorisch getriebene, steuerbare Verstellung des Abstands zwischen den beiden benachbarten Kabinen 12, 14 bewirken kann. Auf diese Weise können die Abstände zwischen Kabinen des Mehrdeckfahrzeugs 10 automatisch an variierende Stockwerksabstände des Aufzugsschachts angepasst werden. Eine solche Kopplungsvorrichtung 24 kann eine Verstelleinrichtung, beispielsweise einen linearen Stellantrieb, umfassen, die in Fig. 1 durch den Pfeil 24.3 symbolisch dargestellt ist. Die Erfindung soll jedoch nicht auf diese Ausführungsform einer Verstelleinrichtung bzw. einer Kopplungsvorrichtung beschränkt sein.According to a preferred embodiment of the invention, the coupling device 24 is designed so that it can cause a motor-driven, controllable adjustment of the distance between the two adjacent cabins 12, 14. In this way, the distances between cabins of the multi-deck vehicle 10 can be automatically adapted to varying floor distances of the hoistway. Such a coupling device 24 may comprise an adjusting device, for example a linear actuator, which in Fig. 1 symbolically represented by the arrow 24.3. However, the invention should not be limited to this embodiment of an adjusting device or a coupling device.

Die Kabinen 12, 14 des Mehrdeckfahrzeugs 10 sind direkt an den Führungsschienen 20 des Aufzugsschachtes geführt, ohne dass ein gemeinsamer Kabinenrahmen vorhanden ist. Die Kabinen 12, 14 müssen daher gegenüber üblichen Einzelkabinen kaum modifiziert werden. Ein grosses Bauteil wie der bei konventionellen Mehrdeckfahrzeugen üblicherweise vorhandene gemeinsame Kabinenrahmen entfällt, was den Transport des Mehrdeckfahrzeugs 10 sowie dessen Montage in einer Aufzugsanlage wesentlich vereinfacht.The cabins 12, 14 of the multi-deck vehicle 10 are guided directly on the guide rails 20 of the elevator shaft, without a common cabin frame is present. The cabins 12, 14 must therefore be hardly modified compared to conventional single cabins. A large component such as the common cabin frame commonly present in conventional multi-deck vehicles is eliminated, which greatly simplifies the transport of the multi-deck vehicle 10 and its installation in an elevator installation.

Aufgrund der direkten Kopplung der Kabinen des Mehrdeckfahrzeugs 10 an die Führungsschienen 20 des Aufzugsschachtes ist zudem das Schwingungsverhalten im Vergleich zu herkömmlichen Konstruktionen mit gemeinsamem Kabinenrahmen verbessert. Dies hat seine Ursache darin, dass bei dem erfindungsgemässen System jede Kabine separat an den Führungsschienen geführt ist und kein grosser und schwerer gemeinsamer Kabinenrahmen mit geringer Eigenfrequenz vorhanden ist. Um die in diesem Bewegungssystem auftretenden Schwingungen weiter zu reduzieren, sind die Führungsschienen 20 vorzugsweise mit schall- und schwingungsdämpfenden Befestigungselementen im Aufzugsschacht montiert.Due to the direct coupling of the cabins of the multi-deck vehicle 10 to the guide rails 20 of the elevator shaft, the vibration behavior is also improved in comparison to conventional designs with a common cab frame. This is due to the fact that in the inventive system each cabin is guided separately on the guide rails and no large and heavy common cabin frame with low natural frequency is present. In order to further reduce the vibrations occurring in this movement system, the guide rails 20 are preferably mounted with sound-absorbing and vibration-damping fastening elements in the elevator shaft.

Ferner ist wenigstens eine der Kabinen 12, 14 des Mehrdeckfahrzeugs 10 mit wenigstens einer Fangvorrichtung 26 ausgestattet. Vorzugsweise sind alle Kabinen 12, 14 des Mehrdeckfahrzeugs 10 mit solchen Fangvorrichtungen ausgestattet. Damit kann entweder eine erhöhte Sicherheit bei einer erforderlichen Aktivierung der Fangvorrichtungen erreicht werden, oder es können die Anforderungen an die einzelnen Fangvorrichtungen reduziert werden, weil die Sicherungsfunktion auf eine grössere Anzahl von Fangvorrichtungen 26 verteilt ist. Im letzteren Fall können daher die einzelnen Fangvorrichtungen 26 einfacher und kostengünstiger ausgebildet sein.Furthermore, at least one of the cars 12, 14 of the multi-deck vehicle 10 is equipped with at least one safety gear 26. Preferably, all cabins 12, 14 of the multi-deck vehicle 10 are equipped with such safety gears. Thus, either an increased security in a required activation of the safety gear can be achieved, or it can be reduced to the requirements of the individual safety gear, because the safety function is distributed over a larger number of safety gears 26. In the latter case, therefore, the individual safety gears 26 can be made simpler and less expensive.

Die Fangvorrichtungen 26 sind jeweils fest mit einer Kabine 12, 14 bzw. mit deren Fangrahmen 12.1, 14.1 verbunden. Sie umfassen zumeist ein Fanggehäuse mit den Fangorganen, Übertragungsorgane und Anschlussorgane für die Auslösung der Fangvorrichtung. Die Fangvorrichtungen 26 werden im Allgemeinen durch einen Geschwindigkeitsbegrenzer aktiviert, wenn eine vorbestimmte Auslösegeschwindigkeit durch das Mehrdeckfahrzeug überschritten wird. Die vorliegende Erfindung soll aber auf keine spezielle Ausführungsform, Anzahl oder Anordnung der Fangvorrichtungen 26 für das Mehrdeckfahrzeug 10 beschränkt sein.The safety gears 26 are each firmly connected to a car 12, 14 or with their catch frame 12.1, 14.1. They usually include a catcher housing with the catch organs, transmission organs and connection organs for the release of the safety gear. The safety gears 26 are generally activated by a speed limiter when a predetermined release speed is exceeded by the multi-deck vehicle. The present invention is intended but limited to any specific embodiment, number or arrangement of the safety gear 26 for the multi-deck vehicle 10.

Bezug nehmend auf Fig. 2 wird nun ein zweites Ausführungsbeispiel der vorliegenden Erfindung näher erläutert. Dabei sind gleiche und ähnliche Komponenten mit den gleichen Bezugsziffern wie im ersten Ausführungsbeispiel gekennzeichnet, und auf eine wiederholte Beschreibung ihrer Konstruktionen und Funktionsweisen wird verzichtet. Es ist wiederum eine Aufzugsanlage dargestellt, die ein Mehrdeckfahrzeug 10 mit einer oberen ersten Kabine 12 und einer unteren zweiten Kabine 14 umfasst. Auch bei dieser Ausführungsform kann das Mehrdeckfahrzeug jedoch mehr als zwei Kabinen umfassen.Referring to Fig. 2 Now, a second embodiment of the present invention will be explained in more detail. Here, the same and similar components are identified by the same reference numerals as in the first embodiment, and a repeated description of their constructions and operations will be omitted. Again, there is shown an elevator installation comprising a multi-deck vehicle 10 having an upper first car 12 and a lower second car 14. However, in this embodiment, the multi-deck vehicle may include more than two cabins.

Bei dem in Fig. 2 gezeigten Ausführungsbeispiel ist das Tragmittel 16 über unterhalb der unteren zweiten Kabine 14 an dieser Kabine angebrachte Umlenkscheiben 27 geführt, um die Kabine 14 und mit dieser das gesamte Mehrdeckfahrzeug 10 zu tragen und anzutreiben. Das Tragmittel und damit das Mehrdeckfahrzeug 10 werden durch den Antrieb 18 angetrieben. Mit der gezeigten Tragmittelanordnung wird ein an sich bekanntes Antriebskonzept mit 2:1-Umhängung realisiert. Selbstverständlich ist eine 2:1-Umhängung auch realisierbar, indem solche Umlenkscheiben oberhalb der obersten Kabine eines Mehrdeckfahrzeugs angebracht werden. Üblicherweise wirkt das Tragmittel 16 in bekannter Weise auch mit einem Gegengewicht zusammen, was in Fig. 2 jedoch nicht dargestellt ist.At the in Fig. 2 In the embodiment shown, the suspension element 16 is guided over deflection pulleys 27 mounted on this cabin below the lower second cabin 14 in order to support and drive the cabin 14 and with it the entire multi-deck vehicle 10. The support means and thus the multi-deck vehicle 10 are driven by the drive 18. With the support means arrangement shown, a known drive concept with 2: 1 suspension is realized. Of course, a 2: 1 suspension is also feasible by such deflecting discs are mounted above the uppermost cabin of a multi-deck vehicle. Usually, the support means 16 cooperates in a known manner with a counterweight, which in Fig. 2 but not shown.

Das Ausführungsbeispiel gemäss Fig. 2 unterscheidet sich von der in Fig. 1 dargestellten Aufzugsanlage insbesondere auch durch die Art der Führung der Kabinen 12, 14 des Mehrdeckfahrzeugs 10. Wie in Fig. 2 gezeigt, ist bei dieser Ausführungsform eine obere Kabine 12 des Mehrdeckfahrzeugs 10 in wenigstens zwei in Bewegungsrichtung des Mehrdeckfahrzeugs voneinander beabstandeten Führungsebenen 12A, 12.B mit Führungselementen 22 versehen, die diese obere Kabine 12 in ihren beiden Führungsebenen unabhängig von Führungselementen weiterer Führungsebenen des Mehrdeckfahrzeugs an den Führungsschienen 20 führen. Eine unterhalb der oberen Kabine 12 angeordnete untere Kabine 14 des Mehrdeckfahrzeugs 10 weist eine erste (obere) Führungsebene 14A auf, in der keine Führungselemente vorhanden sind. Die untere Kabine 14 ist jedoch im Bereich ihrer ersten (oberen) Führungsebene 14A an der benachbarten ersten Kabine 12 des Mehrdeckfahrzeugs geführt. In einer in Bewegungsrichtung des Mehrdeckfahrzeugs von der ersten (oberen) Führungsebene 14A beabstandeten zweiten (unteren) Führungsebene 14B ist die zweite Kabine 14 mit Führungselementen 22 versehen, die die Kabine in dieser zweiten Führungsebene unabhängig von Führungselementen weiterer Führungsebenen des Mehrdeckfahrzeugs an den Führungsschienen 20 führen. Die vorstehend erwähnte Führung der zweiten Kabine 14 an der ersten Kabine 12 erfolgt durch eine die beiden Kabinen 12, 14 verbindende Kopplungsvorrichtung 24. Diese Kopplungsvorrichtung ist auf ihrer unteren Seite starr mit der unteren Kabine 14 und auf ihrer oberen Seite gelenkig mit der oberen Kabine 12 verbunden. Selbstverständlich dient die Kopplungsvorrichtung 24 auch zur Übertragung der Trag- und Antriebskräfte, die bei der Ausführungsform gemäss Fig. 2 von der durch das Tragmittel 16 getragenen unteren Kabine 14 auf die obere Kabine 12 übertragen werden.The embodiment according to Fig. 2 is different from the one in Fig. 1 illustrated elevator system in particular by the type of leadership of the cabins 12, 14 of the multi-deck vehicle 10. As in Fig. 2 shown, in this embodiment, an upper cabin 12 of the multi-deck vehicle 10 in at least two in the direction of movement of the multi-deck vehicle spaced guide planes 12A, 12B provided with guide elements 22, the upper cabin 12 in its two management levels regardless of guide elements further management levels of Mehrdeckfahrzeugs guide the guide rails 20. A arranged below the upper cabin 12 lower cabin 14 of the multi-deck vehicle 10 has a first (upper) management level 14 A, in which no Guide elements are present. However, the lower cabin 14 is guided in the region of its first (upper) management plane 14A on the adjacent first cabin 12 of the multi-deck vehicle. In a second (lower) guide plane 14B spaced from the first (upper) guide plane 14A in the direction of movement of the multi-deck vehicle, the second car 14 is provided with guide elements 22 guiding the car to the guide rails 20 independently of guide elements of further guide planes of the multi-deck vehicle in this second guide plane , The above-mentioned guidance of the second car 14 on the first car 12 is provided by a coupling device 24 connecting the two cars 12, 14. This coupling device is rigid with the lower car 14 on its lower side and with the upper car 12 on its upper side connected. Of course, the coupling device 24 also serves to transmit the carrying and driving forces, which in the embodiment according to Fig. 2 are transmitted from the supported by the support means 16 lower cabin 14 to the upper cabin 12.

Bei einem Mehrdeckfahrzeug 10 in der Ausführungsform gemäss Fig. 2, das mehr als zwei Kabinen umfasst, ist beispielsweise die oberste Kabine 12 in zwei Führungsebenen mit Führungselementen 22 ausgestattet, während alle weiteren Kabinen jeweils nur in einer einzigen Führungsebene mit den Führungsschienen zusammenwirkende Führungselemente 22 aufweisen, die im Bereich ihres Kabinenbodens angebracht sind. In ihrer im Bereich ihrer Kabinendecke liegenden zweiten Führungsebene sind in diesem Fall alle weiteren Kabinen mittels einer Kopplungsvorrichtung 24 an der jeweils darüber liegenden Kabine geführt.In a multi-deck vehicle 10 in the embodiment according to Fig. 2 comprising more than two cabins, for example, the uppermost cabin 12 is provided with guiding elements 22 in two guiding planes, while all other cabins each have guide elements 22 cooperating with the guiding rails only in a single guiding plane, which are mounted in the region of their cabin floor. In their lying in the region of their cabin ceiling second management level all other cabins are guided by means of a coupling device 24 to the respective overlying cabin in this case.

Ein erfindungsgemässes Mehrdeckfahrzeug 10 kann auch so ausgeführt sein, dass die unterste Kabine in zwei Führungsebenen geführt ist und dass alle weiteren Kabinen nur im Bereich ihrer Kabinendecken je eine Führungsebene mit Führungselementen 22 aufweisen, die mit den Führungsschuhen zusammenwirken. In diesem Fall sind alle weiteren Kabinen in ihrer im Bereich des Kabinenbodens liegenden zweiten Führungsebene mittels einer Kopplungsvorrichtung 24 an der jeweils darunter liegenden Kabine geführt.A multi-deck vehicle 10 according to the invention can also be configured such that the lowermost car is guided in two guide planes and that all other cars each have a guide plane with guide elements 22 only in the area of their car ceilings, which interact with the guide shoes. In this case, all other cabins are guided in their lying in the region of the cabin floor second management level by means of a coupling device 24 to the respectively underlying cabin.

Die Kopplungsvorrichtung 24 ist mit einer der jeweils gekoppelten Kabinen 12, 14 starr verbunden, während ihre Verbindung zur anderen Kabine als Gelenkkopplung ausgeführt ist. Dadurch ist gewährleistet, dass die Kopplungsvorrichtung Kräfte nur in Bewegungsrichtung des Mehrdeckfahrzeugs 10 überträgt, so dass sich die Führungselemente der jeweils gekoppelten Kabinen nicht gegenseitig beeinflussen.The coupling device 24 is rigidly connected to one of the respective coupled cabins 12, 14, while their connection to the other cabin is designed as a joint coupling. This ensures that the coupling device transmits forces only in the direction of movement of the multi-deck vehicle 10, so that the guide elements of the respective coupled cabins do not influence one another.

Im Unterschied zu den in Fig. 1 dargestellten Kabinen des Mehrdeckfahrzeugs 10 weisen die Kabinen in der Ausführungsform gemäss Fig. 2 keine Fangrahmen auf. Die Führungselemente 22 wie auch die Fangvorrichtungen 26 sind direkt an den Kabinenkörpern 12.2, 14.2 der Kabinen 12, 14 angebracht. Die Kabinenkörper 12.2, 14.2 dieser Kabinen sind daher als selbsttragende Konstruktion mit ausreichender Stabilität ausgeführt.Unlike the in Fig. 1 shown cabins of the multi-deck vehicle 10 have the cabins in the embodiment according to Fig. 2 no catch frame on. The guide elements 22 as well as the safety gears 26 are directly attached to the cabin bodies 12.2, 14.2 of the cabins 12, 14. The cabin bodies 12.2, 14.2 of these cabins are therefore designed as a self-supporting construction with sufficient stability.

Auch bei einem Mehrdeckfahrzeug 10 in der Ausführungsform gemäss Fig. 2 kann die wenigstens eine Kopplungsvorrichtungen 24 eine Verstelleinrichtung 24.3 umfassen, die eine automatische Verstellung des Abstands zwischen benachbarten Kabinen 12, 14 des Mehrdeckfahrzeugs ermöglicht, um den Abstand zwischen den Bodenniveaus der Kabinen unterschiedlichen Stockwerksabständen eines Gebäudes anzupassen.Also in a multi-deck vehicle 10 in the embodiment according to Fig. 2 For example, the at least one coupling device 24 may include an adjustment device 24.3 that allows automatic adjustment of the distance between adjacent cars 12, 14 of the multi-deck vehicle to adjust the distance between the floor levels of the cars to different floor spacings of a building.

Als Alternative zur vorstehend beschriebenen, Teil der Kopplungsvorrichtung 24 bildenden Verstelleinrichtung 24.3 können die Kabinen 12, 14 des Mehrdeckfahrzeugs 10 wie in Fig. 2 gezeigt einen in Bewegungsrichtung des Mehrdeckfahrzeugs verstellbaren Kabinenboden 28 aufweisen, wobei die Verstellung vorzugsweise mittels einer Verstelleinrichtung 25 (symbolisch durch Pfeil 25 dargestellt) erfolgt, die vorzugsweise durch einen Motor angetriebenen und durch eine Aufzugsteuerung gesteuert ist.
