The shaft door device comprises a shaft door (8) and a shaft door closing means (3), and the cab door device comprises a cab door. The shaft door closing means (3) is operatively connected to the shaft door such that a closing force F2 is exerted onto the shaft door. The aim of the invention is to provide an improved elevator system which allows a quick opening of the shaft door with an energy-efficient and compact door controlling device in particular. This is achieved in that the elevator system further comprises a compensating means (5) which can be operatively connected to the shaft door such that the compensating means (5) compensates for at least a part of the closing force F2 acting on the shaft door at least in phases during the opening process of the shaft door.

Description

Beschreibung Aufzugsystem Die Erfindung betrifft ein Aufzugsystem mit einer Schachttürvorrichtung und einer Kabinentürvorrichtung, sowie eine The invention relates to an elevator system with a shaft door device and a car door device, as well as a
Schachttürvorrichtung und eine Kabinentürvorrichtung. Shaft door device and a car door device.
Aufzugsysteme müssen, insbesondere wenn sie für den Personen- verkehr vorgesehen sind, unterschiedliche Sicherheitsmecha¬ nismen aufweisen, so dass den Anforderungen an die Sicherheit entsprochen wird. Es muss beispielsweise gewährleistet wer¬ den, dass eine geöffnete Schachttür einer Schachttürvorrichtung im nichtgekoppelten Zustand automatisch geschlossen wird, so dass eine Person nicht in den Aufzugsschacht fallen kann. Der Aufzugsschacht ist der Schacht, in welchem die Auf- zugskabine hoch und runter fahren kann. Der nichtgekoppelte Zustand liegt vor, wenn die Kabinentürvorrichtung, welche die Aufzugskabine umfasst, sich nicht an der entsprechenden Posi- tion (Landestelle im Schacht) in dem entsprechenden Schacht der Schachttürvorrichtung befindet. Im nichtgekoppelten Zustand liegt insbesondere keine mechanische Wirkverbindung zwischen der Schachttürvorrichtung und der Kabinentürvorrichtung vor, d.h. sie sind nicht miteinander gekoppelt. Das au- tomatische Schließen der Schachttür muss insbesondere ebenso im stromlosen Zustand der Schachttürvorrichtung gewährleistet werden. Hierfür weist die Schachttürvorrichtung des Aufzugs- systems üblicherweise ein Schachttürschließmittel auf, wel¬ ches dafür sorgt, dass die Schachttür der Schachttürvorrich- tung im geöffneten ungekoppelten Zustand automatisch die geschlossene Stellung einnimmt. Da dieser Mechanismus ebenso im stromlosen Zustand gewährleistet werden soll, kann als Elevator systems must, particularly when they are intended for passenger traffic, having different Sicherheitsmecha ¬ mechanisms, so that complied with the requirements for safety. It must, for example, ensures that the ¬ an open bay door of a landing door device in the uncoupled state is automatically closed so that a person can not fall into the elevator shaft. The elevator shaft is the shaft in which the elevator car can move up and down. The uncoupled state exists when the car door device comprising the elevator car is not located at the corresponding position (landing in the shaft) in the corresponding shaft of the shaft door device. In the uncoupled state, in particular, there is no mechanical operative connection between the shaft door device and the car door device, ie they are not coupled to one another. The automatic closing of the shaft door must be ensured in particular also in the de-energized state of the shaft door device. For this purpose, the hoistway door device of the elevator system usually a shaft door closing means, wel ¬ ches ensures that the landing door of the hoistway door device automatically takes up the closed position in the open uncoupled state. Since this mechanism is also to be ensured in the de-energized state, can as
Schachttürschließmittel kein Elektromotor eingesetzt werden. Das Schachttürschließmittel ist daher meist durch ein Gewicht ausgebildet, welches mittels eines über eine Umlenkrolle ge¬ führten Seilzuges mit der Schachttür derart in Wirkverbindung steht, dass eine Schließkraft F2 auf die Schachttür insbeson¬ dere im geöffneten Zustand ausgeübt wird, so dass die Schachttür in Richtung der geschlossenen Stellung bewegt wird. Die durch das Schachttürschließmittel verursachte Schachttürschließmittel no electric motor can be used. The hoistway door closing means is therefore usually formed by a weight which is connected by means of a deflection roller ge ¬ led cable pull with the shaft door in operative connection that a closing force F2, exerted on the shaft door insbeson ¬ wider in the open state so that the Shaft door is moved in the direction of the closed position. The caused by the shaft door closing means
Schließkraft F2 auf die Schachtür wirkt meist ununterbrochen auf die Schachttür, so dass zum Öffnen der Schachttüre ebenso die entgegen der Öffnungsrichtung wirkende Schließkraft F2 aufgebracht werden muss. Closing force F2 on the shaft door usually acts uninterruptedly on the shaft door, so that in order to open the shaft door, the closing force F2 acting counter to the opening direction has to be applied as well.
Mit einem Aufzugsystem werden mehrere Etagen angefahren. With an elevator system several floors are approached.
Hierbei kann es vorkommen, dass die Schachttüren der einzel- nen Etagen unterschiedlich ausgebildet sind. Folglich kann es vorkommen, dass insbesondere das Schachttürschließmittel und folglich die auf die Schachttür wirkende Schließkraft F2 un¬ terschiedlich ausgebildet ist. Es können somit etagenabhängig unterschiedliche Schließkräfte F2 durch das Schachttür- schließmittel auf die entsprechende Schachttür ausgeübt wer¬ den, welche beim Anfahren der Kabinentürvorrichtung mit der Kabine jeweils zum Öffnen überwunden werden müssen. Wird das Schachttürschließmittel beispielsweise als Gewicht ausgebil¬ det, so hat das Gewicht in Abhängigkeit der vorliegenden Schachttür üblicherweise eine Masse von ca. 3 bis 10 kg. It may happen that the shaft doors of the individual floors are designed differently. Consequently, it is possible that in particular the shaft door closing means and hence the force acting on the shaft door closing force F2 is formed un ¬ differently. It is thus dependent on different floor closing forces F2 exerted by the landing door closing means on the corresponding shaft door who ¬ which must be overcome when starting the car door device with the respective cabin to open. When the shaft door closing means, for example, as a weight ausgebil ¬ det, the weight in dependence of the present shaft door usually has a mass of about 3 to 10 kg.
Um eine Schachtür zu öffnen wird üblicherweise die Kabinen¬ türvorrichtung mit der Schachttürvorrichtung gekoppelt, so dass eine mechanische Wirkverbindung zwischen der Kabinentür- Vorrichtung und der Schachttürvorrichtung hergestellt ist.A shaft door to open the cabins ¬ door means is typically coupled to the shaft door apparatus so that a mechanical operative connection between the Kabinentür- device and the landing door device is made.
Das Koppeln kann beispielsweise mittels eines an der Kabinen¬ türvorrichtung vorhanden Schwerts erfolgen, welches beim Anfahren der Kabinentürvorrichtung zur entsprechenden Position im Schacht (Landestelle im Schacht) mit der Schachttürvor- richtung eine mechanische Wirkverbindung herstellt, so dass durch die Kabinentürvorrichtung Kräfte auf die Schachttürvorrichtung und insbesondere auf dessen Schachttür übertragen werden können, oder umgekehrt. Mittels eines Elektromotors wird üblicherweise eine dieser Türen zum Öffnen direkt ange- trieben. Da im gekoppelten Zustand die beiden Türen miteinander verbunden sind, z.B. mittels des Schwerts, werden ebenso die Kräfte des Elektromotors auf die gekoppelte Tür übertra¬ gen, so dass neben der vom Elektromotor direkt angetriebenen Tür ebenso die mit der direkt angetriebenen Tür gekoppelte Tür mitgeöffnet wird. Wird durch den Elektromotor beispiels¬ weise die Kabinentür direkt geöffnet, so wird mittels der me¬ chanischen Wirkverbindung zwischen der Kabinentür und der Schachtür ebenso die Schachttür geöffnet. Sobald die beiden Türen (Kabinentür und Schachttür) miteinander gekoppelt sind, können somit durch den Elektromotor beide Türen geöffnet werden. Da der Elektromotor meist in der Kabinentürvorrichtung untergebracht ist und die Kabinentür direkt antreibt, wird die Schachttür meist durch die mechanische Wirkverbindung zwischen der Schachttür und der Kabinentür geöffnet. Die Schachtür wird somit indirekt über den Elektromotor geöffnet. The coupling may for example take place by means of a provided on the cabins ¬ door apparatus sword, which produces when starting the car door device for the respective position in the shaft (landing site in the shaft) with the landing door apparatus, a mechanical operative connection, so that by the car door apparatus forces on the hoistway door device, and in particular can be transferred to the shaft door, or vice versa. By means of an electric motor, one of these doors is usually driven directly for opening. Since the two doors are connected to one another in the coupled state, for example by means of the sword, as well the forces of the electric motor coupled to the door übertra ¬ gene so that directly driven by the electric motor in addition to the Door as well as the door coupled with the directly driven door is also opened. Is opened directly by the electric motor ¬ example, the car door, the landing door is opened by means of the me chanical ¬ operative connection between the car door and the hoistway door as well. As soon as the two doors (car door and landing door) are coupled together, both doors can be opened by the electric motor. Since the electric motor is usually housed in the car door device and drives the car door directly, the landing door is usually opened by the mechanical operative connection between the landing door and the car door. The shaft door is thus opened indirectly via the electric motor.
Eine Aufgabe der vorliegenden Erfindung ist es ein verbesser- tes Aufzugsystem bereitzustellen, welches insbesondere ein schnelles Öffnen einer Schachttür mit einem energieeffizienten und kompakten Türsteuergerät ermöglicht. An object of the present invention is to provide an improved elevator system, which in particular allows a quick opening of a landing door with an energy-efficient and compact door control unit.
Diese Aufgabe wird gelöst durch eine Vorrichtung gemäß An- spruch 1, d.h. durch ein Aufzugsystem mit einer Schachttürvorrichtung und einer Kabinentürvorrichtung, wobei die This object is achieved by a device according to claim 1, i. by an elevator system comprising a hoistway door device and a car door device, wherein the
Schachttürvorrichtung eine Schachttür und ein Schachttür- schließmittel umfasst und die Kabinentürvorrichtung eine Ka¬ binentür umfasst, wobei das Schachttürschließmittel mit der Schachttür derart in Wirkverbindung steht, dass eine Schlie߬ kraft F2 auf die Schachttür ausgeübt wird, wobei das Aufzug¬ system ferner ein Kompensationsmittel umfasst, welches derart mit der Schachttür in Wirkverbindung stehen kann, dass zumindest phasenweise während des Öffnungsvorgangs der Schachttür zumindest ein Teil der auf die Schachttür wirkenden Schlie߬ kraft F2 durch das Kompensationsmittel kompensiert wird, so¬ wie durch eine Schachttürvorrichtung nach Anspruch 10 und eine Kabinentürvorrichtung nach Anspruch 11. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen 2 bis 9 angegeben. Der Öffnungsvorgang der Schachttür ist der Zeitraum, in welchem die geschlossene Schachttür den vollständig geöffneten Zustand einnimmt. Der Öffnungsvorgang der Kabinentür ist der Zeitraum, in welchem die geschlossene Kabinentür den voll- ständig geöffneten Zustand einnimmt. Shaft door device comprises a shaft door and a shaft door closing means and the car door device comprises a Ka ¬ binentür, wherein the shaft door closing means is operatively connected to the shaft door, that a closing ¬ force F2 is exerted on the shaft door, wherein the elevator ¬ system further comprises a compensation means , which can be in operative connection with the shaft door in such a way that at least in phases during the opening process of the shaft door at least part of the shaft door acting on the closing force ¬ F2 is compensated by the compensation means, ¬ as by a shaft door device according to claim 10 and a car door device according to Claim 11. Advantageous developments of the invention are specified in the dependent claims 2 to 9. The opening process of the shaft door is the period in which the closed shaft door assumes the fully opened state. The opening process of the car door is the period in which the closed car door assumes the fully opened state.
Das Schachttürschließmittel steht insbesondere mit der The shaft door closing means is in particular with the
Schachtür derart in Wirkverbindung, dass mittels der auf die Schachttür wirkenden Schließkraft F2 die Schachttür im unge- koppelten geöffneten Zustand durch die Schließkraft F2 auto¬ matisch in die geschlossene Stellung bewegt wird. Well door in operative connection, that by means of acting on the shaft door closing force F2 the shaft door in the uncoupled open state by the closing force F2 auto ¬ matically moved to the closed position.
Bei den herkömmlichen Aufzugsystemen ist während des Öffnungsvorgangs der gekoppelten Schacht und Kabinentür wegen der durch das Schachttürschließmittel auf die Schachttür aus¬ geübten Schließkraft F2 eine hohe Last für den die Schachttür öffnenden Elektromotor aufzubringen. Insbesondere bei einer schnellen Beschleunigung der Schachttür in die Öffnungsrichtung ist eine sehr hohe Momentanleistung am verwendeten In the conventional elevator systems during the opening operation of the coupled shaft door and car door is to be applied because of the landing door by the closing means on the landing door from ¬ practiced closing force F2 a high load to which the landing door opening electric motor. Especially with a fast acceleration of the shaft door in the opening direction is used a very high instantaneous power
Elektromotor erforderlich. Diese hohe Momentanleistung hat insbesondere einen enormen Einfluss auf die Baugröße und die Kosten des Elektromotors und des zugehörigen Türsteuergerä¬ tes . Bei dem erfindungsgemäßen Aufzugssystem wird hingegen während des Öffnungsvorgangs der Schachttür zumindest phasenweise mindestens ein Teil der auf die Schachttür wirkenden Schlie߬ kraft F2 durch das Kompensationsmittel kompensiert, so dass die Last am Elektromotor während dieser Kompensationsphase reduziert wird. Ein derartiges Aufzugssystem weist mehrereElectric motor required. This high momentary power in particular has a tremendous impact on the size and the cost of the electric motor and the associated Türsteuergerä ¬ tes. In the elevator system according to the invention, however, during the opening process of the shaft door at least in part at least part of the force acting on the shaft door closing ¬ force F2 compensated by the compensation means, so that the load on the electric motor during this compensation phase is reduced. Such an elevator system has several
Vorteile auf. Der Elektromotor kann beispielsweise für geringere Belastungen ausgelegt werden, insbesondere kann die Mo¬ mentanleistung am Elektromotor reduziert werden. Dadurch, dass das Kompensationsmittel über den Verfahrweg vom ge- schlossenen Zustand der Schachtür zum geöffneten Zustand der Schachtür die aufzubringende Last am Elektromotor zumindest phasenweise reduziert, kann ein kompakterer und kostengünsti¬ ger Elektromotor eingesetzt werden. Durch die niedrige Last für den Elektromotor über den Verfahrweg des Öffnens der Schachttür_kann ferner ein energieeffizienteres und kompakte¬ res Türsteuergerät für das Aufzugsystem eingesetzt werden. Ferner kann die Schachttür schneller geöffnet werden, da wäh- rend des Öffnens zumindest phasenweise zumindest ein Teil der Schließkraft durch das Kompensationsmittel kompensiert wird. Advantages. The electric motor can be designed, for example, for lower loads, in particular, the Mo ¬ mentanleistung can be reduced at the electric motor. Characterized in that the compensation means comprise at least temporarily reduced over the travel from the closed state of the shaft door to the open state of the shaft door, the applied load on the electric motor, a more compact and kostengünsti ¬ ger electric motor can be used. Due to the low load for the electric motor via the travel path of opening the shaft door_ can also be used a more energy efficient and compact ¬ res door control device for the elevator system. Furthermore, the shaft door can be opened more quickly, since during opening at least in phases at least part of the closing force is compensated by the compensating means.
In einer vorteilhaften Ausführungsform der Erfindung wird das Kompensationsmittel mit der Schachttüre derart gekoppelt, dass während mindestens 50% des Öffnungsvorgangs, in Bezug auf den zurückzulegenden Öffnungsweg der Schachttür, eine Kompensation zumindest eines Teils der Schließkraft F2 durch das Kompensationsmittel erfolgt. In einer weiteren vorteilhaften Ausführungsform der Erfindung ist das Kompensationsmittel mit der Schachttür derart in Wirkverbindung, dass während des gesamten Öffnungsvorgangs der Schachttür eine Kompensation der Schließkraft durch das Kompensationsmittel erfolgt. In an advantageous embodiment of the invention, the compensating means is coupled to the shaft door such that during at least 50% of the opening operation, with respect to the opening path of the shaft door to be covered, a compensation of at least a part of the closing force F2 by the compensation means. In a further advantageous embodiment of the invention, the compensating means is operatively connected to the shaft door in such a way that compensation of the closing force by the compensating means takes place during the entire opening process of the shaft door.
In einer weiteren vorteilhaften Ausführungsform der Erfindung ist das Kompensationsmittel derart ausgebildet, dass eine vollständige Kompensation der auf die Schachttür wirkenden Schließkraft F2 erfolgen kann. Vorzugsweise wird durch das Kompensationsmittel während des Öffnungsvorgangs eine Kraft auf die Schachttür ausgeübt, welche größer als die Schlie߬ kraft F2 ist. In a further advantageous embodiment of the invention, the compensating means is designed such that a complete compensation of the forces acting on the shaft door closing force F2 can take place. Preferably, a force is applied to the hoistway door by the compensation means during the opening operation which is greater than the closing force ¬ F2.
In einer vorteilhaften Ausführungsform der Erfindung ist das Kompensationsmittel und/oder das Schachttürschließmittel je¬ weils ein Energiespeicher. Der Energiespeicher ist z.B. eine Feder, ein elastisches Element oder ein Gewicht. Insbesondere übt der Energiespeicher ebenso im stromlosen Zustand die gleiche Kraft auf die mit ihm gekoppelte Komponente aus. Wird beispielsweise das Kompensationsmittel und das Schachttür¬ schließmittel jeweils durch ein Gewicht ausgebildet, so kann das jeweilige Gewicht potentielle Energie aufnehmen bzw. ab¬ geben und somit speichern. Mittels einer entsprechenden Ver- bindung mit der jeweiligen Tür (z.B. mittels eines über eine Umlenkrolle geführten Seils) kann das Gewicht in Wirkverbin¬ dung mit der Tür stehen, so dass Kräfte übertragbar sind. Unter dem Energiespeicher ist insbesondere kein Elektromotor zu verstehen. In an advantageous embodiment of the invention, the compensation means and / or the shaft door closing means depending ¬ weils an energy storage. The energy storage is eg a spring, an elastic element or a weight. In particular, the energy storage also exerts the same force on the coupled with him component in the de-energized state. For example, if the compensation means and the shaft door ¬ closing means are each formed by a weight, the respective weight can absorb potential energy and give off ¬ and thus save. By means of an appropriate Bonding with the respective door (eg by means of a guided over a pulley rope), the weight can be in Wirkverbin ¬ tion with the door, so that forces are transferable. Under the energy storage is in particular no electric motor to understand.
In einer weiteren vorteilhaften Ausführungsform der Erfindung kann lediglich im gekoppelten Zustand der Kabinentürvorrich- tung mit der Schachttürvorrichtung zumindest ein Teil der auf die Schachttür wirkenden Schließkraft F2 durch das Kompensa¬ tionsmittel kompensiert werden. Folglich kann im gekoppelten Zustand die auf die Schachttür wirkende Kraft in Richtung der geschlossen Stellung der Schachttür reduziert oder aufgehoben werden. Das Kompensationsmittel wird somit lediglich zum Öff- nen der Schachttür mit der Schachttür gekoppelt. Im ungekoppelten Zustand wird die auf die Schachttür wirkende Schlie߬ kraft F2 nicht durch dass Kompensationsmittel reduziert. Auf diese Weise kann gewährleistet werden, dass das automatische Schließen der Schachttür im geöffneten ungekoppelten Zustand selbstständig erfolgen kann und im gekoppelten Zustand eine Reduzierung der für den Elektromotor anzutreibenden Last zumindest phasenweise während des Öffnungsvorgangs erfolgen kann . Vorzugsweise wird das Kompensationsmittel im Moment der Kopp¬ lung der Kabinentür mit der Schachttür mit der Schachttürvorrichtung gekoppelt. Das Koppeln des Kompensationsmittels er¬ folgt vorzugsweise mittels einer Mechanik in Verbindung mit dem Türschwert (Türkoppelmechanismus für Kabinentür und In a further advantageous embodiment of the invention, only in the coupled state of the Kabinentürvorrich- device with the shaft door device, at least a portion of the force acting on the shaft door closing force F2 be compensated by the Kompensa ¬ tion means. Consequently, in the coupled state, the force acting on the shaft door can be reduced or eliminated in the direction of the closed position of the shaft door. The compensation means is thus coupled with the shaft door only to open the shaft door. In the uncoupled state, the force acting on the shaft door closing ¬ force F2 is not reduced by that compensation means. In this way it can be ensured that the automatic closing of the shaft door in the open uncoupled state can be done independently and in the coupled state, a reduction of the load to be driven for the electric motor at least in phases during the opening process can take place. Preferably, the compensation means is coupled at the moment of Kopp ¬ ment of the car door with the shaft door with the shaft door device. The coupling of the compensation means he ¬ preferably follows by means of a mechanism in conjunction with the door sash (door double mechanism for car door and
Schachttür) . Zur Geräuschminimierung können zusätzlich auch Laufrollen oder ähnliches verwendet werden. Shaft door). To minimize noise can also be used in addition rollers or the like.
In einer weiteren vorteilhaften Ausführungsform der Erfindung ist die durch das Kompensationsmittel auf die Schachttürvor- richtung wirkende Kraft zumindest zweitweise während des Öff¬ nungsvorgangs der Schachttür größer als die Schließkraft F2 oder gleich der Schließkraft F2. Hierbei werden insbesondere die Kräfte (Schließkraft F2 und die an der Schachttürvorrich- tung wirkende Kraft des Kompensationsmittels) am selben An¬ griffspunkt an der Schachttürvorrichtung (vorzugsweise an der Schachttür) betrachtet. In einer weiteren vorteilhaften Ausführungsform der Erfindung umfasst die Kabinentürvorrichtung das Kompensationsmittel. Folglich muss nicht jede Schachttürvorrichtung des Aufzugsystems ein Kompensationsmittel aufweisen, da dieses durch die Kabinentürvorrichtung bereitgestellt wird. Durch das mechani- sehe Koppeln der Kabinentürvorrichtung mit der entsprechenden Schachttürvorrichtung kann eine Kraftübertragung zwischen den beiden Vorrichtungen erfolgen, so dass durch das Kompensationsmittel eine Reduzierung der auf die Schiebetür wirkenden Schließkraft F2 in Richtung der geschlossen Stellung erfolgen kann. In a further advantageous embodiment of the invention the force applied by the compensation means to the Schachttürvor- direction in at least two, during the drying process Publ ¬ the shaft door is greater than the closing force F2 or equal to the clamping force F2. In particular, the forces (closing force F2 and at the shaft door tion acting force of the compensation means) at the same on ¬ grip point on the shaft door device (preferably on the shaft door) considered. In a further advantageous embodiment of the invention, the car door device comprises the compensation means. Consequently, not every hoistway door device of the elevator system needs to have a compensation means, as this is provided by the car door device. Due to the mechanical coupling of the car door device with the corresponding shaft door device, a force transmission between the two devices can take place, so that the compensating means can reduce the closing force F2 acting on the sliding door in the direction of the closed position.
In einer weiteren vorteilhaften Ausführungsform der Erfindung übt das Kompensationsmittel in der geschlossenen Stellung der Kabinentür eine Zuhaltekraft auf die Kabinentür aus, so dass die Kabinentür zugehalten wird. Das Kompensationsmittel ist insbesondere derart ausgebildet, dass mittels der Zuhalte¬ kraft des Kompensationsmittels im stromlosen geschlossenen Zustand der Kabinentürvorrichtung die Kabinentür die geschlossene Stellung ohne Einwirkung einer externen Kraft (z.B. durch eine Person) beibehält. In a further advantageous embodiment of the invention, the compensation means in the closed position of the car door exerts a locking force on the car door, so that the car door is locked. The compensation means is designed in particular such that the car door (for example, by one person) by means of the retaining Zuhalte ¬ force of the compensation means in the currentless closed state of the car door apparatus, the closed position without the action of an external force.
In einer weiteren vorteilhaften Ausführungsform der Erfindung umfasst die Kabinentürvorrichtung einen Elektromotor, welcher während des Öffnungsvorgangs der Kabinentür mit der Kabinen- tür und der mit der Kabinentür gekoppelten Schachttür derart in Wirkverbindung treten kann, dass beide Türen durch den Elektromotor geöffnet werden können. Alternativ hierzu kann die Schachttürvorrichtung einen Elektromotor umfassen, welcher während des Öffnungsvorgangs der Schachttür mit der Schachttür und der mit der Schachttür gekoppelten Kabinentür derart in Wirkverbindung steht, dass beide Türen durch den Elektromotor geöffnet werden können. In einer weiteren vorteilhaften Ausführungsform der Erfindung übt das Schachttürschließmittel eine Schließkraft F2 auf die Schachttür aus, so dass die geöffnete Schachtüre im ungekop¬ pelten Zustand der Schachttürvorrichtung mit der Kabinentür- Vorrichtung durch die Schließkraft F2 geschlossen wird. Die Schließkraft F2 sorgt somit für das Schließen der Schachttür, sofern die Kabinentürvorrichtung nicht mit der Schachttürvorrichtung gekoppelt ist. Das Schachttürschließmittel übt somit eine Schließkraft auf die Schachttüre aus, welche eine geöff- nete Schachttür in Richtung der geschlossenen Stellung derIn a further advantageous embodiment of the invention, the car door device comprises an electric motor, which during the opening process of the car door with the car door and coupled with the car door shaft door can be operatively connected in such a way that both doors can be opened by the electric motor. Alternatively, the hoistway door device may comprise an electric motor operatively connected to the hoistway door and the car door coupled to the hoistway door during the opening operation of the hoistway door such that both doors can be opened by the electric motor. In a further advantageous embodiment of the invention, the shaft door closing means exerts a closing force F2 on the shaft door, so that the open shaft door is closed in ungekop ¬ pelt state of the shaft door device with the car door device by the closing force F2. The closing force F2 thus ensures the closing of the shaft door, provided that the car door device is not coupled to the shaft door device. The shaft door closing means thus exerts a closing force on the shaft door, which opens an open shaft door in the direction of the closed position of the shaft door
Schachttüre bewegen kann. Zum Öffnen der Schachttür im gekoppelten Zustand muss diese Schließkraft F2 ebenso aufgebracht werden. Dank des Kompensationsmittels kann diese Schließkraft zumindest phasenweise reduziert oder vollständig aufgehoben werden. Ein schnelleres und leistungseffizienteres Öffnen der Schachttüre kann somit ermöglicht werden. Can move the shaft door. To open the shaft door in the coupled state, this closing force F2 must also be applied. Thanks to the compensating means, this closing force can be at least reduced in phases or completely eliminated. A faster and more efficient opening the shaft door can thus be made possible.
In einer weiteren vorteilhaften Ausführungsform der Erfindung umfasst die Schachttürvorrichtung das Kompensationsmittel. Es kann somit etagenabhängig ein genau auf das Schachttürschließmittel abgestimmtes Kompensationsmittel in der In a further advantageous embodiment of the invention, the shaft door device comprises the compensation means. It can thus dependent on the floor a precisely matched to the shaft door closing means compensating in the
Schachttürvorrichtung verbaut werden, so dass eine optimale Kompensation der Schließkraft F2 im gekoppelten Zustand der Schachttürvorrichtung mit der Kabinentürvorrichtung während des Öffnungsvorgangs erfolgen kann. Vorzugsweise tritt wäh¬ rend der Koppelung der Kabinentürvorrichtung mit der Schachttürvorrichtung das auf das Schachttürschließmittel abgestimm¬ te Kompensationsmittel mit der Schachttürvorrichtung in Wirkverbindung, so dass zumindest phasenweise während des Öff¬ nungsvorgangs der Schachttür zumindest ein Teil der Schlie߬ kraft F2 kompensiert wird. Shaft door device are installed, so that an optimal compensation of the closing force F2 can be done in the coupled state of the shaft door device with the car door device during the opening process. Preferably, the coupling of the car door apparatus occurs currency ¬ rend with the hoistway door device, the on the shaft door closing means concerted ¬ te the compensation means to the hoistway door device in operative connection so that at least temporarily during the Publ ¬ drying process at least a part of the closing ¬ force is compensated F2 of the hoistway door.
In einer weiteren vorteilhaften Ausführungsform der Erfindung beginnt das Öffnen der Schachttür mit einem zeitlichen Verzug zum Öffnen der Kabinentür. Vorzugsweise wird zunächst die Ka¬ binentür soweit geöffnet, bis das Kompensationsmittel derart positioniert ist, dass es die an der Schachttür wirkende Schließkraft F2 für den Elektromotor kompensieren kann. Dar- aufhin wird ebenso die Schachttür geöffnet. Auf diese Weise kann die für den Elektromotor aufzubringende Leistung verringert werden und ein schnelles Öffnen der Kabinen- und In a further advantageous embodiment of the invention, the opening of the shaft door begins with a time delay for opening the car door. Preferably, the Ka ¬ binentür is first opened so far until the compensating means is positioned so that it can compensate for acting on the shaft door closing force F2 for the electric motor. representation At the same time, the shaft door is opened. In this way, the power to be applied to the electric motor can be reduced and a quick opening of the cabin and
Schachttür gewährleistet werden. Der zeitliche Verzug kann beispielsweise mittels der Koppelvorrichtung zwischen der Ka- binentürvorrichtung und der Schachttürvorrichtung, insbesondere zwischen der Kabinentür und der Schachttür, erfolgen. Das Öffnen der Schachttür erfolgt somit vorzugsweise ab dem Zeitpunkt, in welchem die durch das Kompensationsmittel auf die Schachttür ausgeübte Kraft die durch die Schließkraft F2 für den Elektromotor erzeugte Kraft reduzieren kann. Shaft door to be guaranteed. The time delay can, for example, by means of the coupling device between the Kä binentürvorrichtung and the shaft door device, in particular between the car door and the shaft door done. The opening of the shaft door is thus preferably from the time in which the force exerted by the compensation means on the shaft door force can reduce the force generated by the closing force F2 for the electric motor.
In einer weiteren vorteilhaften Ausführungsform der Erfindung wird die Wirkverbindung des Kompensationsmittels auf die Schachttüre während des Koppelvorgangs der Kabinentürvorrich- tung mit der Schachtürvorrichtung hergestellt und bei einem Entkoppeln der Kabinentürvorrichtung mit der Schachtürvorrichtung gelöst. In einer weiteren vorteilhaften Ausführungsform der Erfindung wird durch das Kompensationsmittel eine Öffnungs- und/oder Zuhaltehilfe für die Kabinentür und/oder Schachttür bereitgestellt, auch wenn kein Gegengewicht an der Schachttür vorhanden ist. Mittels des Kompensationsmittels kann somit das Zu- halten der Kabinentür sichergestellt werden und/oder ein verbessertes Öffnen der Kabinentür und/oder Schachttür ermöglicht werden. In a further advantageous embodiment of the invention, the operative connection of the compensating means to the shaft door during the coupling process of the Kabinentürvorrich- device is made with the shaft door device and released when decoupling the car door device with the shaft door device. In a further advantageous embodiment of the invention, an opening and / or locking aid for the car door and / or shaft door is provided by the compensation means, even if no counterweight is present at the shaft door. By means of the compensating means, it is thus possible to ensure that the car door is locked and / or that an improved opening of the car door and / or shaft door is made possible.
Die der Erfindung zugrunde liegende Idee ist ebenso anwendbar bei Türen oder Toren jeglicher Art, wie z.B. Schiebetüren,The idea underlying the invention is equally applicable to doors or gates of any kind, e.g. sliding doors,
Bahnsteigabschlusstüren, Werkzeugmaschinentüren, Schutztore, Kühlraumtore . Platform entrance doors, machine tool doors, protective gates, refrigerator doors.
Im Folgenden werden die Erfindung und Ausgestaltungen der Er- findung anhand der in den Figuren dargestellten Ausführungsbeispiele näher beschrieben und erläutert.

Bei der folgenden Betrachtung des Aufzugsystems nach FIG 1 bis 3 wird von einem idealen System ausgegangen, bei welchem die Reibungskräfte außer Betracht bleiben. In the following consideration of the elevator system according to FIGS. 1 to 3, an ideal system is assumed in which the frictional forces are disregarded.
FIG 1 zeigt eine schematische Darstellung eines Aufzugsystems mit geschlossenen Türen. Das Aufzugssystem umfasst eine Ka- binentürvorrichtung und je anzusteuernde Etage eine Schacht¬ türvorrichtung . 1 shows a schematic representation of an elevator system with closed doors. The elevator system includes a Ka binentürvorrichtung and ever to be controlled floor a shaft ¬ door device.
Die Kabinentürvorrichtung umfasst eine Kabinentür, über welche Personen die Kabine betreten und verlassen können. Die abgebildete Kabinentür weist die geschlossene Stellung auf, so dass derzeit keine Person die Kabine betreten bzw. verlas- sen kann. Die Kabinentür umfasst zwei Türflügel 4, welche zum Öffnen in eine entgegengesetzte Richtung bewegt werden. Zum elektrischen Öffnen bzw. Schließen der Kabinentür umfasst die Kabinentürvorrichtung einen Elektromotor 9, ein Antriebsritzl 15, einen Riemen 6, eine Umlenkrolle 1 und je Türflügel 4 der Kabinentür einen Türmitnehmer 7, welcher mit dem entsprechenden Türflügel 4 der Kabinentür und dem Riemen 6 verbunden ist. Mittels des Elektromotors 9 kann das Antriebsritzl 15 angetrieben werden, so dass durch das Antriebsritzl 15 der Riemen 6 bewegt werden kann. Der Riemen 6 ist über das An- triebsritzl 15 und der Umlenkrolle 1 gespannt und weist zwei Türmitnehmer 7 auf, so dass er die vom Elektromotor 9 über das Antriebsritzl 15 übertragene Kraft mittels der Türmit¬ nehmer 7 an die Kabinentür übertragen kann, so dass die Tür- flügel 4 der Kabinentür gleichmäßig geöffnet bzw. geschlossen werden können. The car door device comprises a car door, via which persons can enter and leave the car. The cabin door shown has the closed position, so that at the moment no person can enter or leave the cabin. The car door comprises two door leaves 4, which are moved in an opposite direction for opening. For electrically opening or closing the car door, the car door device comprises an electric motor 9, a drive pin 15, a belt 6, a deflection roller 1 and per door leaf 4 of the car door a Türmitnehmer 7, which is connected to the corresponding door 4 of the car door and the belt 6 , By means of the electric motor 9, the Antriebsritzl 15 can be driven, so that by the Antriebsritzl 15 of the belt 6 can be moved. The belt 6 is stretched over the drive scrub 15 and the deflection roller 1 and has two Türmitnehmer 7, so that it can transmit the transmitted from the electric motor 9 via the Antriebsritzl 15 force by means of Türmit ¬ takers 7 to the car door, so that the Door- 4 wings of the car door can be opened or closed evenly.
Die Schachttürvorrichtung umfasst eine Schachttür, welche zwei Türflügel 8 umfasst, drei Umlenkrollen 1, einen Riemen 11, zwei Türmitnehmer 2, ein zweites Befestigungsmittel 16, ein zweites Seil 14 und ein Schachttürschließmittel 3. Der Riemen 11 ist über zwei Umlenkrollen 1 gespannt, so dass eine Kraftübertragung über den Riemen erfolgen kann. Jeder Türflü- gel 8 der Schachttür ist mittels des zugehörigen Türmitnehmers 2 mit dem Riemen 11 befestigt, so dass bei einer Bewe¬ gung des Riemens 11 in eine Richtung, die Schachttür gleichmäßig geöffnet werden kann und bei einer Bewegung des Riemens 11 in die entgegengesetzte Richtung die Schachttür gleichmä- ßig geschlossen werden kann. Die Schachttürvorrichtung weist aus Sicherheitsgründen das Schachttürschließmittel 3 auf, welches dafür sorgt, dass die Schachttüre aus dem ungekoppel¬ ten ganz oder teilweise geöffneten Zustand automatisch die geschlossene Stellung einnimmt. Auf diese Weise kann bei- spielsweise verhindert werden, dass eine Schachttür offen steht, obwohl sich die Aufzugskabine in einer anderen Etage befindet. Im vorliegenden Ausführungsbeispiel ist das The shaft door device comprises a shaft door, which comprises two door leaves 8, three guide rollers 1, a belt 11, two door drivers 2, a second attachment means 16, a second cable 14 and a shaft door closing means 3. The belt 11 is stretched over two deflection rollers 1, so that a power transmission can take place via the belt. Each door leaf 8 of the landing door is fastened by means of the associated Türmitnehmers 2 with the belt 11, so that at a ¬ movement of the belt 11 in one direction, the shaft door can be opened evenly and upon movement of the belt 11 in the opposite direction the shaft door can be closed evenly. The landing door apparatus includes for security reasons the shaft door closing means 3, which ensures that the shaft door automatically takes up the closed position from the ungekoppel ¬ th fully or partially opened state. In this way it can be prevented, for example, that a shaft door is open, although the elevator car is located on another floor. In the present embodiment, the
Schachttürschließmittel 3 durch ein Gewicht ausgebildet, wel¬ ches mittels des über die Umlenkrolle 1 geführten zweiten Seils 14 mit einem Türflügel der Schachttür verbunden ist. Hierfür ist das erste Ende des zweiten Seils 14 mittels des zweiten Befestigungsmittels 16 mit einem der Türflügel 8 der Schachttür und das zweite Ende des zweiten Seils 14 mit dem Schachttürschließmittel 3 verbunden. Das zweite Seil 14 ist über die Umlenkrolle 1 geführt, so dass eine gezielte Kraft¬ übertragung auf die Schachttür erfolgen kann. Es ist ebenso denkbar, dass das erste Ende des Seils 14 direkt mit dem Rie¬ men 11 verbunden ist und so eine Kraft in Richtung der geschlossenen Stellung der Schachttür auf die Schachttür ausge- übt wird. Das Schachttürschließmittel 3 steht somit mit der Schachttür derart in Wirkverbindung, dass eine Schließkraft F2 auf die Schachttür, insbesondere auf einen Türflügel 8 der Schachttür, ausgeübt wird, so dass die Schachttür in Richtung der geschlossenen Stellung bewegt werden kann. Figur 1 zeigt die geschlossene Stellung der Schachttür und der Kabinentür. Das als Gewicht ausgebildete Schachttürschließmittel 3 übt somit mittels des über die Umlenkrolle 1 geführten zweiten Seils 14 auf einen der Türflügel 8 der Schachtüre eine Shaft door closing means 3 formed by a weight, wel ¬ Ches is connected by means of the guided over the guide roller 1 second cable 14 with a door of the landing door. For this purpose, the first end of the second cable 14 is connected by means of the second fastening means 16 with one of the door leaf 8 of the shaft door and the second end of the second cable 14 with the shaft door closing means 3. The second cable 14 is guided over the deflection roller 1, so that a targeted power ¬ transmission can be done on the shaft door. It is also conceivable that the first end of the cable 14 is connected directly to the Rie ¬ men 11 and so a force in the direction of the closed position of the shaft door on the shaft door is practiced. The shaft door closing means 3 is thus operatively connected to the shaft door such that a closing force F2 is exerted on the shaft door, in particular on a door leaf 8 of the shaft door, so that the shaft door in the direction the closed position can be moved. Figure 1 shows the closed position of the shaft door and the car door. Trained as a weight shaft door means 3 thus exercises by means of guided over the guide roller 1 second cable 14 on one of the door 8 of the door a
Schließkraft F2 aus. Da beide Türflügel 8 der Schachttür über den Riemen 11 miteinander gekoppelt sind, wird diese Schlie߬ kraft F2 ebenso auf den anderen Türflügel übertragen, so dass ein Schließen der Schachttür erfolgen kann. Closing force F2 off. Since both doors 8 of the landing door are coupled to each other via the belt 11, this closing ¬ force F2 is also transferred to the other door panel, so that a closing of the shaft door can be carried out.
Die durch das Schachttürschließmittel 3 verursachte Schlie߬ kraft F2 wirkt ununterbrochen auf die Schachttür, so dass zum Öffnen der Schachttür ebenso die Schließkraft F2 überwunden werden muss. Caused by the landing door closing means 3 ¬ closing force F2 acts continuously on the landing door, so that the closing force F2 has to be overcome as well as for opening the landing door.
Zum Öffnen der Schachttür wird zunächst die Kabinentür mit der Schachttür mittels eines nicht abgebildeten Koppelungs¬ mittels gekoppelt. Die Koppelung kann beispielsweise mittels eines Türschwerts erfolgen. Das Türschwert stellt beim Anfah- ren der Kabinentürvorrichtung zum entsprechenden Schacht mit der Schachttürvorrichtung eine mechanische Wirkverbindung her, so dass durch die Kabinentürvorrichtung Kräfte auf die Schachttürvorrichtung übertragen werden können. Insbesondere wird beim Koppeln der Kabinentürvorrichtung mit der Schacht- türvorrichtung die Kabinentür mit der Schachttür mittels des Kopplungsmittels gekoppelt. Wird folglich die Kabinentür ge¬ öffnet, so wird durch das Kopplungsmittel ebenso eine Kraft auf die Schachttür übertragen, so dass ebenso die Schachttür geöffnet wird. Der Elektromotor 9 der Kabinentürvorrichtung sorgt somit ebenso für das Öffnen der Schachttür. For opening the landing door, the cage door with the shaft door by means of a not shown Coupling ¬ is first coupled means. The coupling can be done for example by means of a door sword. The door sash establishes a mechanical operative connection with the bay door device when the car door device approaches the corresponding shaft, so that forces can be transmitted to the shaft door device by the car door device. In particular, when the car door device is coupled to the manhole door device, the car door is coupled to the landing door by means of the coupling means. Thus, when the car door opens ge ¬, a force is transmitted to the shaft door by means of the coupling means as well, so that as the shaft door is opened. The electric motor 9 of the car door device thus also ensures the opening of the shaft door.
Zum Öffnen der Schachttür muss insbesondere die durch das Schachttürschließmittel 3 hervorgerufene Schließkraft F2 überwunden werden. To open the shaft door in particular caused by the shaft door closing means 3 closing force F2 must be overcome.
Zur Minimierung der für das Öffnen der Kabinentür und To minimize the need for opening the cabin door and
Schachttür am Elektromotor 9 aufzubringenden Last umfasst die Kabinentürvorrichtung ferner ein Kompensationsmittel 5, ein erstes Seil 13, zwei Umlenkrollen 1 und ein erstes Befesti¬ gungsmittel 12. Im gekoppelten Zustand steht das Kompensati¬ onsmittel 5 mit der Schachttür derart in Wirkverbindung, dass während des Öffnungsvorgangs der Schachttür 8 die auf die Schachttür wirkenden Schließkraft F2 durch das Kompensations¬ mittel 5 kompensiert wird. Shaft door to be applied to the electric motor 9 load, the car door device further comprises a compensation means 5, a first cable 13, two guide rollers 1, and a first Fixed To ¬ restriction means 12. In the coupled state is the Kompensati ¬ onsmittel 5 with the shaft door in operative connection that during the opening process of the hoistway door 8 acting on the shaft door closing force F2 by the compensation ¬ medium 5 is compensated.
Hierfür ist das Kompensationsmittel 5, welches als ein Ge¬ wicht ausgebildet ist, über das erste Seil 13 mit dem Riemen 6 verbunden. Das erste Seil 13 ist mit dem ersten Ende mit dem Kompensationsmittel 5 verbunden und mit dem anderen Ende mittels eines ersten Befestigungselements 12 mit dem Riemen 6 verbunden. Das erste Seil 13 wird über zwei Umlenkrollen 1 geführt, so dass eine gezielte Kraftübertragung des Kompensa- tionsmittels 5 auf den Riemen 6 und somit auf die Kabinentür erfolgen kann. For this purpose, the compensation means 5, which is designed as a Ge ¬ weight, connected via the first cable 13 with the belt 6. The first cable 13 is connected to the first end with the compensation means 5 and connected to the other end by means of a first fastener 12 with the belt 6. The first cable 13 is guided over two deflecting rollers 1, so that a targeted power transmission of the compensating means 5 can take place on the belt 6 and thus on the car door.
Das Kompensationsmittel 5 übt somit eine Kraft Fl auf den Riemen 6 aus. Dadurch, dass das Befestigungsmittel 12 kurz vor einer Umlenkrolle 1 platziert ist, kann die durch dasThe compensation means 5 thus exerts a force Fl on the belt 6. Due to the fact that the fastening means 12 is placed shortly before a deflection roller 1, the through the
Kompensationsmittel 5 erzeugt Kraft Fl dafür sorgen, dass im geschlossenen Zustand der Kabinentür beispielsweise bei einem Stromausfall die Kabinentür mit der Kraft Fl zugehalten wird, so dass ein versehentliches Öffnen der Kabinentür verhindert werden kann. Compensation means 5 generates force Fl ensure that in the closed state of the car door, for example, in a power failure, the car door is held with the force Fl, so that accidental opening of the car door can be prevented.
Im vorliegenden Ausführungsbeispiel ist die durch das Kompen¬ sationsmittel 5 am Riemen 6 erzeugte Kraft Fl gleich der durch das Schachttürschließmittel 3 erzeugten Schließkraft F2. Die Kraft F2 kann aber ebenso größer oder kleiner der Schließkraft Fl sein. In the present embodiment, the produced by the Kompen ¬ sationsmittel 5 on the belt 6 is equal to the force F generated by the shaft door closing means 3 closing force F2. However, the force F2 can also be greater or smaller than the closing force F1.
Die Koppelung der Kabinentür mit der Schachttür ist vorzugsweise derart ausgebildet, dass die zur Öffnung der Schachttür erforderliche Kraftübertragung von der Kabinentür auf dieThe coupling of the car door with the shaft door is preferably designed such that the force required to open the shaft door power transmission from the car door on the
Schachtür erst dann erfolgt, wenn das erste Befestigungsmit¬ tel 12 auf dem Riemen 6 derart positioniert ist, dass die Kraft Fl unterstützend zum Elektromotor 9 wirkt. Dies ist insbesondere der Zeitpunkt, ab dem die vom Kompensationsmit¬ tel 5 am Riemen 6 erzeugte Kraft Fl zumindest teilweise in die Bewegungsrichtung des ersten Befestigungsmittels 12 wirkt . Chute door only then takes place when the first Befestigungsmit ¬ tel 12 is positioned on the belt 6 such that the force Fl supporting the electric motor 9 acts. This is in particular, the time at which the generated from Kompensationsmit ¬ tel 5 on the belt 6 force Fl acts at least partially in the direction of movement of said first fastener 12th
Der Elektromotor 9 muss somit zum Öffnen der Kabinentür zunächst die Kraft Fl aufbringen. Nachdem das erste Befesti¬ gungsmittel 12 den Scheitelpunkt der Rolle 1 passiert hat un¬ terstütz das Kompensationsmittel 5 den Öffnungsvorgang der Kabinentür. Da ab diesem Zeitpunkt die mechanische Kraftüber¬ tragung zwischen der Kabinentür und der Schachttür mittels des Koppelungsmittels erfolgt, kann mittels des Kompensati¬ onsmittels 5 die durch das Schachtürschließmittel 3 erzeugte Schließkraft F2 kompensiert werden. Da die am Riemen 6 er- zeugte Kraft Fl des Kompensationsmittels 5 gleich der an der Schachttür 8 wirkenden Schließkraft F2 ist kann der Kraftaufwand zum Öffnen der Kabinentür und/oder Schachttür erheblich verbessert werden. Der Energieverbrauch des Elektromotors und der der Steuerung kann erheblich minimiert werden. Ein schnelles Öffnen der Türen ist somit mit einfacheren Mitteln (z.B. kleinere und kostengünstiger Steuerungen) möglich. The electric motor 9 must therefore first apply the force Fl to open the car door. After the first Fixed To ¬ supply medium un ¬ terstütz 12 passes the apex of the roller 1 the compensation means 5 the process of opening the car door. As from this time, the mechanical power transmission ¬ transmission between the car door and the landing door is effected by means of the coupling means, the closing force generated by the bay door closing means 3 F2 can be compensated by means of the Kompensati ¬ onsmittels. 5 Since the force Fl of the compensating means 5 generated on the belt 6 is equal to the closing force F2 acting on the shaft door 8, the force required to open the car door and / or shaft door can be considerably improved. The energy consumption of the electric motor and the controller can be significantly minimized. A fast opening of the doors is thus possible with simpler means (eg smaller and less expensive controls).
Das Kompensationsmittel 5 sorgt somit insbesondere für eine Minimierung der vom Elektromotor 9 aufzubringenden Leistung für den Öffnungsvorgang der Kabinentür und der Schachttür.The compensation means 5 thus ensures, in particular, a minimization of the power to be applied by the electric motor 9 for the opening operation of the car door and the shaft door.
Ferner erfolgt eine Krafteinsparung für das Halten einer geöffneten Schacht und/oder Kabinentür in ihrer geöffneten Stellung sowie für das Halten der geschlossenen Kabinentür in ihrer geschlossenen Stellung. Das Aufzugsystem kann somit im Vergleich zu herkömmlichen Aufzugsystemen mit einem günstigeren und kompakteren Elektromotor 9 sowie mit günstigeren und kompakteren Türsteuergeräten betrieben werden. Furthermore, there is a saving in power for holding an open shaft and / or cabin door in its open position and for holding the closed cabin door in its closed position. The elevator system can thus be operated in comparison to conventional elevator systems with a cheaper and more compact electric motor 9 and with cheaper and more compact door control units.
FIG 2 zeigt eine schematische Darstellung des Aufzugsystems aus FIG 1, bei welchem die Kabinentür teilweise geöffnet ist und die Schachttür geschlossen ist. Die Türflügel 4 der Kabi¬ nentür sind folglich bereits einen Spalt geöffnet. Das erste Befestigungsmittel 12 befindet sich in FIG 2 am Scheitelpunkt der Umlenkrolle 1. Von nun an wirkt die durch das Kompensati¬ onsmittel 5 am Riemen erzeugte Kraft Fl unterstützend zu der durch den Elektromotor am Riemen 6 zum Öffnen zu erzeugenden Kraft. Da die am Riemen 6 erzeugte Kraft Fl des Kompensati- onsmittels 5 gleich der durch das Schachttürschließmittel 3 erzeugten Schließkraft F2 ist wird die durch das Schachttürschließmittel 3 erzeugte Schließkraft kompensiert. Die Kraft¬ übertragung zwischen der Kabinentür und Schachttür erfolgt vorzugsweise während des Öffnungsvorgangs der Kabinentür ab dem Überschreiten des Scheitelpunktes der Rolle 1 durch das erste Befestigungsmittel 12. Ab diesem Zeitpunkt unterstützt das Kompensationsmittel 5 den Öffnungsvorgang der Kabinentür und der Schachttüre, so dass ein schnelles Öffnen der Kabi¬ nentür und insbesondere der Schachttür mittels eines kompak- teren Elektromotors und Türsteuergeräts erfolgen kann. Es ist ebenso denkbar, dass die durch das Kompensationsmittel 5 auf¬ gebrachte Kraft Fl größer oder kleiner der Schließkraft F2 ist . FIG 3 zeigt eine schematische Darstellung des Aufzugsystems aus FIG 1 und FIG 2, bei welchem die Kabinentür und die 2 shows a schematic representation of the elevator system of FIG 1, in which the car door is partially open and the shaft door is closed. The door leaves 4 of the Kabi ¬ nentür are therefore already opened a gap. The first attachment means 12 is located in FIG 2 at the apex the deflection roller 1. From now on, generated by the Kompensati ¬ onsmittel 5 on the belt force Fl is supportive to be generated by the electric motor to the belt 6 for opening force. Since the force Fl of the compensating means 5 generated on the belt 6 is equal to the closing force F2 generated by the shaft door closing means 3, the closing force generated by the shaft door closing means 3 is compensated. The power ¬ transmission between the car door and shaft door is preferably carried out during the opening process of the car door from the crossing of the apex of the roller 1 by the first fastener 12. From this point the compensation means 5 supports the opening process of the car door and the shaft door, so that a fast opening the Kabi ¬ nentür and in particular the shaft door can be done by means of a compact electric motor and door control device. It is also conceivable that the accommodated by the compensation means 5 ¬ force Fl is larger or smaller than the closing force F2. FIG. 3 shows a schematic illustration of the elevator system from FIG. 1 and FIG. 2, in which the car door and the
Schachttür teilweise geöffnet sind. Es ist ersichtlich, dass die durch das Kompensationsmittel 5 auf dem Riemen 6 erzeugte Kraft Fl unterstützend für den Elektromotor 9 wirkt. Die Kraft Fl wirkt bezüglich der zum Öffnen der Kabinentür undShaft door are partially open. It can be seen that the force Fl generated on the belt 6 by the compensating means 5 acts to support the electric motor 9. The force Fl acts with respect to the opening of the car door and
Schachtür aufzubringenden Kraft in die entgegengesetzte Richtung wie die durch das Schachttürschließmittel 3 erzeugte Schließkraft F2, so dass die zum Öffnen der beiden Türen aufzubringenden Kräfte reduziert werden. Mittels des Kompensati- onsmittels 5 kann somit eine Kompensation der Schließkraft F2 erfolgen, so dass ein verbessertes Aufzugsystem vorliegt. Chest door applied force in the opposite direction as the closing force F2 generated by the shaft door closing means 3, so that the forces to be applied to open the two doors are reduced. By means of the compensating means 5, a compensation of the closing force F2 can thus take place, so that an improved elevator system is present.
Das Kompensationsmittel 5 und Schachttürschließmittel 3 ist im vorliegenden Ausführungsbeispiel als Gewicht ausgebildet. Es ist ebenso denkbar, dass das das Kompensationsmittel 5 und Schachttürschließmittel 3 durch eine Feder oder einen anderen Energiespeicher ausgebildet ist. Ebenso sind andere Konstruk¬ tive Ausführungsformen, bei welchen durch ein Kompensations- mittel während des Öffnungsvorgangs der Schiebetür die durch das Schachttürschließmittel 3 erzeugte Schließkraft F2 ver¬ ringert wird denkbar. Hierbei kann insbesondere die Anzahl der Rollen 1 variieren, der Riemen 6,11 oder der Seilzug durch ein alternatives Kraftübertragungsmittel ersetzt wer¬ den, die Positionierung des Kompensationsmittels 5 und/oder Elektromotors 9 variieren (z.B. an der Schachttürvorrichtung) , die mechanische Wirkverbindung zwischen dem Schachttürschließmittel 3 und der Schachttür variieren (z.B. erfolgt die Kraftübertragung über den Riemen 11 der Schachttürvorrichtung) , etc .. The compensation means 5 and shaft door closing means 3 is formed in the present embodiment as a weight. It is also conceivable that the compensation means 5 and shaft door closing means 3 is formed by a spring or other energy storage. Likewise, other constructive ¬ tive embodiments in which by a compensation medium during the opening operation of the sliding door, the closing force generated by the shaft door closing means 3 F2 is ver ¬ Ringert conceivable. In this case, in particular, the number of rollers 1 vary, the belt 6,11 or the cable replaced by an alternative power transmission ¬ who, the positioning of the compensation means 5 and / or electric motor 9 vary (eg on the shaft door device), the mechanical operative connection between the Shaft door closing means 3 and the shaft door vary (for example, power is transmitted through the belt 11 of the hoistway door device), etc.
