Description

Die vorliegende Erfindung betrifft eine Türantriebsvorrichtung mit Verriegelungsmechanismus für Aufzüge, bei welcher im Bereich der Etagen eine mit einer Schachttür durch einen Kupplungsmechanismus formschlüssig verbindbare Kabinentür von einem Antrieb bewegbar ist, wobei der Kupplungsmechanismus aus einem an einem Kabinentürflügel gelagerten Mitnehmerparallelogramm und zwei jeweils an jeder Schachttür angeordneten Kupplungsrollen besteht und der Antrieb ein über der Kabine angeordneter Antriebsmotor, ein Vorgelege und ein Antriebsmittel aufweist, welches mit der Kabinentür durch einen Betätigungshebel verbunden ist und die Kabinentür in der geschlossenen und in der offenen Stellung fixiert und der Verriegelungsmechanismus einen durch einen Sicherheitskontakt überwachten, schwenkbar gelagerten, an einem Anschlag arretierbaren Kabinentürriegel aufweist, welcher durch das Eigengewicht in einer Haltestellung verriegelt und durch eine auf eine Steuerkurve auflaufende Steuerrolle in eine Freigabestellung drückbar ist.The present invention relates to a door drive device with a locking mechanism for lifts, in which a cabin door which can be positively connected to a shaft door by a coupling mechanism can be moved by a drive in the area of the floors, the coupling mechanism comprising a driver parallelogram mounted on a cabin door wing and two arranged on each shaft door Coupling rollers exist and the drive has a drive motor arranged above the cabin, a countershaft and a drive means which is connected to the cabin door by an actuating lever and fixes the cabin door in the closed and in the open position and the locking mechanism pivots a monitored by a safety contact Has mounted, lockable at a stop car door latch, which locks in a stop position by its own weight and by a Steuerr olle can be pressed into a release position.

Eine derartige Türantriebsvorrichtung ist mit der CH-PS 663 406 bekanntgeworden, bei welcher die Schachttür gemeinsam durch die Kabinentür einer im Bereich eines Stockwerkes sich befindenden Aufzugskabine bewegt wird. Mit Hilfe eines an der Kabinentür gelagerten, durch zwei an der Schachttür angeordnete Mitnehmer hindurchfahrbaren Mitnehmerparallelogrammes werden die beiden Türen formschlüssig miteinander gekuppelt. An der Kabinentür ist ein schwenkbar gelagerter Riegel angeordnet, welcher durch sein Eigengewicht an einem an der Kabine angeordneten Anschlag verriegelt ist. Im Bereich eines Zielstockwerkes wird der Riegel durch das Auflaufen einer durch ein an einem gelenkig mit dem Riegel verbundenen Winkelhebel angeordneten ersten Steuerrolle auf eine in jedem Stockwerk angeordnete Steuerkurve entriegelt, wobei im Normalbetrieb die gekuppelten Türen durch die Türantriebsvorrichtung automatisch geöffnet und wieder geschlossen werden.Such a door drive device has become known from CH-PS 663 406, in which the shaft door is moved together through the car door of an elevator car located in the area of a floor. With the help of a driver parallelogram mounted on the cabin door, which can be driven through two drivers arranged on the shaft door, the two doors are positively coupled to one another. A pivoted bolt is arranged on the cabin door, which is locked by its own weight to a stop arranged on the cabin. In the area of a target floor, the bolt is arranged by the running up of an angle lever connected to the bolt in an articulated manner unlocked the first control roller on a control cam arranged on each floor, the coupled doors being opened and closed automatically by the door drive device in normal operation.

Bei Stromausfall bleibt die Kabinentür ausserhalb der Stockwerke verriegelt. Im Bereich der Stockwerke wird das Mitnehmerparallelogramm durch die Kraft einer Zugfeder auseinandergezogen, wobei mit Hilfe eines Doppelhebels und einer zweiten Steuerrolle einerseits der Türantrieb aus einer Totpunktlage geführt und anderseits die Verriegelung der Kabinentür durch das Auftreffen der ersten Steuerrolle auf die an jeder Schachttür angeordneten Steuerkurve und die damit verbundene Bewegung des Winkelhebels und des angelenkten Riegels entriegelt wird. Die Kabinentür und die gekuppelte Schachttür können von Hand geöffnet werden.In the event of a power failure, the cabin door outside the floors remains locked. In the area of the floors, the driver parallelogram is pulled apart by the force of a tension spring, with the help of a double lever and a second control roller on the one hand guiding the door drive from a dead center position and on the other hand locking the cabin door by the impact of the first control roller on the control cam arranged on each shaft door and the associated movement of the bell crank and the articulated bolt is unlocked. The cabin door and the coupled shaft door can be opened by hand.

Ein Nachteil dieser Vorrichtung liegt darin, dass in jeder Etage eine Steuerkurve für die Entriegelung der Kabinentürverriegelung erforderlich ist, welche in jeder Etage genau mit der an der Kabine angeordneten Antriebsvorrichtung zusammenarbeiten muss und deshalb auf der Baustelle genaue und aufwendige Regulierarbeiten erfordert. Ein weiterer Nachteil liegt auch darin, dass das Mitnehmerparallelogramm in der offenen Stellung durch äussere Kräfte oder Trägheitskräfte zusammengedrückt werden kann, wodurch störende Geräusche entstehen.A disadvantage of this device is that a control curve is required for unlocking the cabin door lock on each floor, which cam must cooperate precisely with the drive device arranged on the cabin on each floor and therefore requires precise and complex regulation work on the construction site. Another disadvantage is that the driver parallelogram can be compressed in the open position by external forces or inertial forces, which causes disturbing noises.

Der Erfindung liegt die Aufgabe zugrunde, eine Türantriebsvorrichtung vorzuschlagen, bei welcher an den einzelnen Schachttüren keine Steuerkurven für die Entriegelung der Kabinentürverriegelung anzuordnen sind und bei welcher das offene Mitnehmerparallelogramm durch äussere Kräfte oder durch Trägheitskräfte nicht zusammengedrückt werden kann.The invention is based on the object of proposing a door drive device in which no control cams for unlocking the cabin door lock are to be arranged on the individual shaft doors and in which the open driver parallelogram cannot be compressed by external forces or by inertial forces.

Diese Aufgabe wird durch die im Anspruch 1 gekennzeichnete Erfindung gelöst.This object is achieved by the invention characterized in claim 1.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass eine einzige an der beweglichen Kurve des Mitnehmerparallelogrammes angeordnete Betätigungskurve und eine direkt am Kabinentürriegel angeordnete Steuerrolle genügen, um den Kabinentürriegel im Bereich eines Stockwerkes zu entriegeln, während sie die Kabinentürverriegelung ausserhalb der Stockwerke nicht beeinflussen. Ein weiterer Vorteil liegt auch darin, dass das für eine einwandfreie Funktion des Mitnehmerparallelogrammes erforderliche genaue Spreizmass des Mitnehmerparallelogrammes dadurch einstellbar ist, dass der Schwenkwinkel des zwischen zwei fest plazierten elastischen Anschlägen schwenkbaren Betätigungshebels durch zwei gegeneinander verschiebbare Teile des Betätigungshebels einstellbar ist. Mit diesen Anordnungen ist es bereits bei der Werksmontage möglich, die genaue Wirkungsweise des Mitnehmerparallelogrammes einzustellen. Ein weiterer Vorteil liegt noch darin, dass das Mitnehmerparallelogramm bei entriegelter Kabinentürverriegelung nach minimalem Öffnungsweg der Kabinen- und der Schachttür durch eine von einer an der Kabine angeordneten Stützrolle in einer Ruhelage getragenen Sperrklinke durch die Kraft einer Torsionsfeder abkippt und in offenem Zustand mit dem eingestellten Spreizmass gesperrt wird. Die Betätigungselemente der Verriegelungen sind zudem so angeordnet, dass kein Verklemmen, auch bei ungenauer seitlicher Kabinenposition, möglich ist.The advantages achieved by the invention are essentially to be seen in the fact that a single actuation curve arranged on the movable curve of the driver parallelogram and a control roller arranged directly on the car door latch are sufficient to unlock the car door latch in the area of a floor, while they unlock the car door lock outside the floors do not affect. Another advantage lies in the fact that the exact spreading dimension of the driver parallelogram required for a proper function of the driver parallelogram can be adjusted by the fact that the pivoting angle of the actuating lever which can be pivoted between two fixed elastic stops is adjustable by means of two parts of the actuating lever which can be displaced relative to one another. With these arrangements, it is already possible to set the exact mode of operation of the driver parallelogram during factory assembly. Another advantage lies in the fact that when the car door lock is unlocked, the driver parallelogram tilts after a minimal opening of the car and shaft doors by a pawl carried by a support roller arranged on the car in a rest position by the force of a torsion spring and in the open state with the adjusted spreading dimension is blocked. The actuating elements of the locks are also arranged so that no jamming is possible, even if the cabin position is inaccurate.

In den Fig. 3, 4, 5 und 6 ist wieder mit 1 das Mitnehmerparallelogramm bezeichnet. Das Mitnehmerparallelogramm 1 besteht aus einer starren Kurve 2 und einer beweglichen Kurve 3, welche durch einen unteren Hebel 7 und einen oberen Hebel 8 gelenkig und parallel schwenkbar mit einer festen Grundplatte 10 verbunden sind. Die Grundplatte 10 ist fest am Oberteil der Kabinentür 30 angeordnet. Die bewegliche Kurve 3 weist einen am unteren und am oberen Hebel 7, 8 angelenkten, starren Kurventräger 4 und eine durch Blattfedern 6 vom starren Kurventräger 4 leicht distanzierte, an diesem parallel zussammendrückbar befestigte Auflaufkurve 5 auf. Das Mitnehmerparallelogramm 1 wird durch eine am oberen Hebel 8 und am unteren Teil der Grundplatte 10 angelenkte Zugfeder 11 in eine offene Stellung auseinandergezogen, bzw. durch ein bandförmiges Antriebsmittel 42 in eine geschlossene Stellung zusammengezogen. Als Bindeglied zwischen dem Mitnehmerparallelogramm 1 und dem bandförmigen Antriebsmittel 42 dient ein am oberen 42.1 oder am unteren Trum 42.2 des bandförmigen Antriebsmittels 42 anklemmbares Klemmelement 19, welches gelenkig mit einem am oberen Hebel 8 des Mitnehmerparallelogrammes 1 einstellbar befestigten Betätigungshebel 9 verbunden und durch eine zusätzliche Lasche 18 parallel bewegbar geführt ist. Die offene Stellung des Mitnehmerparallelogrammes 1 wird durch einen an der Grundplatte 10 angeordneten Anschlag 16, die geschlossene Stellung durch einen ebenfalls an der Grundplatte 10 angeordneten Anschlag 17 limitiert. Der genaue Schwenkwinkel zum Erreichen der vorgeschriebenen Öffnungsbreite des Mitnehmerparallelogrammes kann durch leichtes Verschieben des Betätigungshebels 9 auf dem oberen Hebel 8 eingestellt werden. Auf der Grundplatte 10 ist ein Kabinentürriegel 12 kippbar gelagert, welcher durch sein Eigengewicht und durch eine zusätzliche Druckfeder 15 auf einen an der Grundplatte 10 angeordneten Anschlag 13 in einer Ruhelage aufliegt. In der Ruhelage ist der Kabinentürriegel 12 mit einem an der Kabine 33 angeordneten Anschlag 25 verriegelt. Am Kabinentürriegel 12 ist eine Steuerrolle 14 befestigt, welche mit einer an der Auflaufkurve 5 der beweglichen Kurve 3 angeordneten Steuerkurve 24 des Mitnehmerparallelogrammes 1 zusammenspielt und den Kabinentürriegel 12 entriegelt, wenn das Mitnehmerparallelogramm 1 mit einer festen Kupplungsrolle 44 und einer beweglichen Kupplungsrolle 45 einer Schachttür 43 gekuppelt ist. Die verriegelte Ruhestellung des Kabinentürriegels 12 wird durch einen Sicherheitskontakt 20 elektrisch überwacht. An der Grundplatte 10 ist eine Sperrklinke 23 kippbar gelagert, welche durch die Kraft einer Torsionsfeder 22 vorgespannt ist. Eine an der Kabine angeordnete Stützrolle 21 drückt gegen die Kraft der Torsionsfeder 22 die Sperrklinke bei geschlossener Kabinentür 30 in eine Entriegelungsstellung. Unmittelbar nach dem Öffnen der Kabinentür 30 rollt die schräge Kante 23.1 der Sperrklinke 23 über die Stützrolle 21, wobei die Sperrklinke 23 kippt, bis ein Anschlagstift 26 für die Torsionsfeder 22 an einer Nase 27 der Grundplatte 10 ansteht und der hintere Teil 23.2 der Sperrklinke 23 an einer Fase 9.1 des Betätigungshebels 9 ansteht und das Mitnehmerparallelogramm 1 in der geöffneten Stellung sperrt.3, 4, 5 and 6, the driver parallelogram is again designated by 1. The entrained parallelogram 1 consists of a rigid curve 2 and a movable curve 3, which are connected in an articulated and parallel pivotable manner to a fixed base plate 10 by a lower lever 7 and an upper lever 8. The base plate 10 is fixedly arranged on the upper part of the cabin door 30. The movable curve 3 has a rigid cam carrier 4 articulated on the lower and the upper lever 7, 8 and a run-up cam 5 slightly distanced from the rigid cam carrier 4 by leaf springs 6 and fastened to this in parallel compressible manner. The driver parallelogram 1 is shown by a tension spring 11 articulated on the upper lever 8 and on the lower part of the base plate 10 is pulled apart into an open position, or pulled together by a band-shaped drive means 42 into a closed position. The link between the parallel parallelogram 1 and the band-shaped drive means 42 is a clamping element 19 which can be clamped to the upper 42.1 or the lower run 42.2 of the band-shaped drive means 42 and which is connected in an articulated manner to an actuating lever 9 which is adjustably fastened to the upper lever 8 of the parallel parallelogram 1 and by an additional strap 18 is guided movably in parallel. The open position of the driver parallelogram 1 is limited by a stop 16 arranged on the base plate 10, the closed position by a stop 17 also arranged on the base plate 10. The exact swivel angle for reaching the prescribed opening width of the driver parallelogram can be adjusted by slightly moving the actuating lever 9 on the upper lever 8. On the base plate 10, a cabin door latch 12 is tiltably mounted, which due to its own weight and an additional compression spring 15 rests on a stop 13 arranged on the base plate 10 in a rest position. In the rest position, the car door latch 12 is locked with a stop 25 arranged on the car 33. A control roller 14 is fastened to the car door latch 12, which interacts with a control curve 24 of the driver parallelogram 1 arranged on the run-up curve 5 of the movable curve 3 and unlocks the cabin door latch 12 when the driver parallelogram 1 with a fixed clutch roller 44 and a movable clutch roller 45 of a shaft door 43 is coupled. The locked rest position of the car door bolt 12 is monitored electrically by a safety contact 20. On the base plate 10, a pawl 23 is pivotally mounted, which is biased by the force of a torsion spring 22. A support roller 21 arranged on the cabin presses against the force of the Torsion spring 22 the pawl when the car door 30 is closed in an unlocked position. Immediately after opening the cabin door 30, the inclined edge 23.1 of the pawl 23 rolls over the support roller 21, the pawl 23 tilting until a stop pin 26 for the torsion spring 22 is against a nose 27 of the base plate 10 and the rear part 23.2 of the pawl 23 is applied to a chamfer 9.1 of the actuating lever 9 and locks the driver parallelogram 1 in the open position.

Die vorstehend beschriebene Einrichtung arbeitet wie folgt: Die in den Fig. 1 und 2 beispielsweise dargestellte zentralöffnende Teleskoptür besteht aus zwei zweiflügeligen Teleskoptüren. Beim Öffnen der Kabinentür 30 verschieben sich je zwei Türflügel 30.1, 30.2, bzw. 30.3, 30.4 nebeneinander von der Mitte aus nach links bzw. nach rechts, und zwar mittels einer bekannten, nicht dargestellten Einrichtung, bei welcher je der äussere, indirekt angetriebene Türflügel 30.1, 30.4 bei halber Geschwindigkeit den halben Weg der inneren, direkt angetriebenen Türflügel 30.2, 30.3 ausführt, so dass bei offener Kabinentür 30 je die beiden zusammengehörigen Türflügel 30.1, 30.2; 30.3, 30.4 seitlich auserhalb der Kabinentüröffnung genau deckend hintereinander liegen. Die einzelnen Kabinentürflügel sind in Führungen des Führungsträgers 35 verschiebbar geführt. Ein gemeinsamer, auf dem Blechträger 34 über dem Führungsträger 35 am Kabinendach aufgebauter Antrieb 36 treibt die beiden mittleren Kabinentürflügel 30.2, 30.3 an. Vom Antriebsmotor 37 wird über den Treibriemen 39, das Vorgelege 38 und die feste Antriebsrolle 40 das über die spannbare Umlenkrolle 41 gelegte bandförmige Antriebsmittel 42 angetrieben, an dessen oberem Trum 42.1 das Mitnehmerparallelogramm 1 des linken mittleren Kabinentürflügels 30.2 und an dessen unterem Trum 42.2 das Mitnehmerparallelogramm 1 des rechten mittleren Kabinentürflügels 30.3 festgeklemmt sind. Die Befestigung des Mitnehmerparallelogramms 1 am bandförmigen Antriebsmittel 42 und die Funktionsweise dieses Mitnehmerparallelogramms 1 geht deutlicher aus den Fig. 3, 4, 5 und 6 hervor.The device described above works as follows: The central opening telescopic door shown in FIGS. 1 and 2 consists of two double-leaf telescopic doors. When the car door 30 is opened, two door leaves 30.1, 30.2 or 30.3, 30.4 each move side by side from the center to the left or to the right, by means of a known device (not shown), in each of which the outer, indirectly driven door leaf 30.1, 30.4 at half the speed executes half the path of the inner, directly driven door leaves 30.2, 30.3, so that when the cabin door 30 is open, the two associated door leaves 30.1, 30.2; 30.3, 30.4 lie exactly behind each other on the side outside the cabin door opening. The individual car door wings are guided in guides of the guide bracket 35. A common drive 36, built on the sheet metal support 34 above the guide support 35 on the cabin roof, drives the two middle cabin door leaves 30.2, 30.3. The drive motor 37 drives the belt-shaped drive means 42 placed over the tensionable deflection roller 41 via the drive belt 39, the countershaft 38 and the fixed drive roller 40, the driver parallelogram 1 of the left middle cabin door leaf 30.2 on its upper run 42.1 and the driver parallelogram on its lower run 42.2 1 of the right middle cabin door wing 30.3 are clamped. The attachment of the driver parallelogram 1 to the belt-shaped drive means 42 and the mode of operation of this driver parallelogram 1 can be seen more clearly from FIGS. 3, 4, 5 and 6.

Das mittels einer Grundplatte 10 fest am Oberteil des zugehörigen Kabinentürflügels 30.2, 30.3 angeordnete Mitnehmerparallelogramm 1 hat die Aufgabe, die Kabinentür 30 während der Fahrt verriegelt zu halten und in einer Zieletage die Kabinentür 30 und die Schachttür 43 zu entriegeln und zusammenzukuppeln, damit die Schachttür 43 gemeinsam mit der vom Türantrieb 36 betätigten Kabinentür 30 geöffnet und geschlossen wird und anschliessend beide Türen wieder verriegelt werden. Zusätzlich sind noch die Vorschriften zu erfüllen, dass bei Stromausfall die Kabinentür ausserhalb einer Stockwerketage verriegelt bleiben muss, bzw. im Bereich der Etagen die Kabinentür und die entsprechende Schachttür automatisch entriegelt werden, damit die Kabinentür gemeinsam mit der Schachttür von einem eingeschlossenen Fahrgast von Hand geöffnet werden kann. Die Fig. 3 zeigt die geschlossene Stellung des Mitnehmerparallelogrammes 1 für die freie Fahrt und die Durchfahrt durch nicht angesteuerte Etagen, die Fig. 4 die offene Stellung bei Stromausfall mit verriegelter Kabinentür 30 auserhalb einer Stockwerketage und die Fig. 5 und 6 die offene Stellung im Normalbetrieb oder bei Stromausfall mit entriegelter Kabinentür 30 innerhalb der Türöffnungszone einer Stockwerksetage. Das gemäss Fig. 3 am bandförmigen Antriebsmittel 42 festgeklemmte Klemmelement 19 hält durch eine an ihm wirkende Haltekraft 50 des unteren Trums 42.2 des bandförmigen Antriebsmittels 42, bei ausgeschaltetem, durch eine nicht dargestellte Haltebremse blockiertem Antriebsmotor 37, einerseits das Mitnehmerparallelogramm 1 gegen die Kraft der Zugfeder 11 in der geschlossenen Stellung und anderseits die Kabinentür 30 selbst, ebenfalls geschlossen. Das unter der Zugspannung stehende Klemmelement 19 zieht den angelenkten Betätigungshebel 9 des oberen Hebels 8 satt an den Anschlag 17 der Grundplatte 10 an, so dass auch die starre Kurve 2 und die bewegliche Kurve 3 bei vom starren Kurventräger 4 durch die Blattfedern 6 abstehender Auflaufkurve 5 ihre engste Stellung einnehmen. Die Steuerrolle 14 und die Steuerkurve 24 des Kabinentürriegels 12 berühren sich nicht, der Kabinentürriegel 12 liegt durch sein Eigengewicht und die Kraft der Druckfeder 15 auf dem Anschlag 13 auf. Die Kabinentür 30 ist durch den Kabinentürriegel 12 am Anschlag 25 verriegelt und der Sicherheitskontakt 20 ist geschlossen. Die entriegelte Sperrklinke 23 des Mitnehmerparallelogrammes 1 ruht in ihrer Ruhelage gegen die Kraft der Torsionsfeder 22 auf der Stützrolle 21 auf. Bei dieser für die Fahrt der Kabine 33 geschlossenen Stellung des Mitnehmerparallelogramms 1 fährt das Mitnehmerparalleogramm 1 im Bereich einer nicht angesteuerten Etage ohne Berührung zwischen der festen Kupplungsrolle 44 und der beweglichen Kupplungsrolle 45 der Schachttür 43 hindurch. Bei einem Halt der Kabine 33 ausserhalb der Türöffnungszone einer Etage, z.B. bei Stromausfall, gemäss Fig. 4, entfällt die Zugkraft durch ein Trum 42.1, 42.2 des bandförmigen Antriebsmittels 42 am Klemmelement 19 durch den stromlosen Antriebsmotor 37. Die Zugkraft der Zugfeder 11 kippt den Betätigungshebel 9 vom Anschlag 17 zum Anschlag 16 der Grundplatte 10. Das Klemmelement 19 führt dabei zusammen mit dem angeklemmten bandförmigen Antriebsmittel 42 bei stillstehender Kabinentür 30 in einer parallelen Verschiebung einen Leerhub aus. Die starre und die bewegliche Kurve 2, 3 des Mitnehmerparallelogrammes 1 nehmen die offene Stellung ein, die zusammendrückbare Auflaufkurve 5 bleibt durch die Blattfedern 6 vom starren Kurventräger 4 distanziert, die Steuerkurve 24 und die Steuerrolle 14 des Kabinentürriegels 12 berühren sich nicht. Die Kabinentür 30 bleibt durch den am Anschlag 25 anstehenden Kabinentürriegel 12 verriegelt und die Sperrklinke 23 zum Mitnehmerparallelogramm 1 verharrt in ihrer Ruhelage.The carrier parallelogram 1, which is fixedly arranged on the upper part of the associated car door leaf 30.2, 30.3 by means of a base plate 10, has the task of keeping the car door 30 locked while driving and of unlocking and coupling the car door 30 and the shaft door 43 on a target floor, so that the shaft door 43 is opened and closed together with the car door 30 actuated by the door drive 36 and then both doors are locked again. In addition, the regulations must be met that in the event of a power failure, the cabin door must remain locked outside one floor, or that the cabin door and the corresponding shaft door in the area of the floors are automatically unlocked so that the cabin door and the shaft door are opened manually by an enclosed passenger can be. Fig. 3 shows the closed position of the driver parallelogram 1 for free travel and passage through uncontrolled floors, Fig. 4 shows the open position in the event of a power failure with a locked cabin door 30 outside one floor and Figs. 5 and 6 the open position in Normal operation or in the event of a power failure with the car door 30 unlocked within the door opening zone of a floor. The clamping element 19 clamped to the band-shaped drive means 42 according to FIG. 3 holds on the one hand the driver parallelogram 1 against the force of the tension spring by means of a holding force 50 acting thereon of the lower run 42.2 of the band-shaped drive means 42 when the drive motor 37 is switched off and blocked by a holding brake (not shown) 11 in the closed position and on the other hand the cabin door 30 itself, also closed. The tension element 19 under tension draws the articulated actuating lever 9 of the upper lever 8 to the stop 17 of the base plate 10, so that the rigid curve 2 and the movable curve 3 also pass through from the rigid cam carrier 4 the leaf springs 6 protruding ramp 5 assume their narrowest position. The control roller 14 and the control cam 24 of the car door bolt 12 do not touch, the car door bolt 12 rests on the stop 13 due to its own weight and the force of the compression spring 15. The cabin door 30 is locked by the cabin door latch 12 at the stop 25 and the safety contact 20 is closed. The unlocked pawl 23 of the driver parallelogram 1 rests in its rest position against the force of the torsion spring 22 on the support roller 21. In this closed position of the driver parallelogram 1 for the travel of the cabin 33, the driver parallelogram 1 travels in the region of an uncontrolled floor without contact between the fixed coupling roller 44 and the movable coupling roller 45 of the shaft door 43. If the cabin 33 is stopped outside the door opening zone of a floor, for example in the event of a power failure, according to FIG. 4, the tensile force is eliminated by a strand 42.1, 42.2 of the band-shaped drive means 42 on the clamping element 19 by the currentless drive motor 37. The tensile force of the tension spring 11 tilts the Actuating lever 9 from stop 17 to stop 16 of base plate 10. Clamping element 19, together with clamped band-shaped drive means 42, performs an idle stroke in a parallel displacement when cabin door 30 is stationary. The rigid and the movable curve 2, 3 of the driver parallelogram 1 assume the open position, the compressible run-up curve 5 remains distanced from the rigid cam carrier 4 by the leaf springs 6, the control curve 24 and the control roller 14 of the car door bolt 12 do not touch. The car door 30 remains locked by the car door latch 12 present at the stop 25 and the pawl 23 for the driver parallelogram 1 remains in its rest position.

Bei einem angesteuerten oder einem ungewollten Halt innerhalb der Türöffnungszone einer Etage, gemäss den Fig. 5 und 6, führt das Mitnehmerparallelogramm 1 zwischen die feste und die bewegliche Kupplungsrolle 44, 45 der Schachttür 43. Das Mitnehmerparallelogramm 1 wird durch die Zugkraft der Zugfeder 11 entweder bei stromlosem Antriebsmotor 37 oder beim Umschalten des durch einen Mikroprozessor geregelten Antriebsmotors 37 in die Öffnungsrichtung auseinandergespreizt. Das am bandförmigen Antriebsmittel 42 angeklemmte Klemmelement 19 führt zusammen mit dem Antriebsmittel 42 bei stillstehender Kabinentür 30 durch den Betätigungshebel 9 eine Schwenkbewegung aus, bei welcher sich die feste und die bewegliche Kurve 2, 3 parallel öffnen und an den Kupplungsrollen 44, 45 der Schachttür auflaufen. Dabei wird die bewegliche Kupplungsrolle 45 um eine gewisse Distanz weggedrückt und die Schachttür 43 entriegelt und die bewegliche Auflaufkurve 5 an den starren Kurventräger 4 gepresst, wobei die Steuerrolle 14 auf die Steuerkurve 24 aufläuft, der Kabinentürriegel 12 aus seiner Ruhelage gedrückt und die Kabinentür 30 entriegelt wird. Die Kabinentür 30 wird nun je nach dem Zustand entweder durch den Türantrieb 36 geöffnet oder kann von Hand aufgedrückt werden. Am Anfang dieser Bewegung rollt die Sperrklinke 23 auf der Stützrolle 21 ab und kippt nach wenigen Millimetern durch die Kraft der Torsionsfeder 22 über die schräge Kante 23.1 nach unten, bis der Anschlagstift 26 für ein Federende der Torsionsfeder 22 an der Nase 27 der Grundplatte 10 ansteht (Fig. 6). Der hintere Teil 23.2 der Sperrklinke 23 steht an der Fase 9.1 des Betätigungshebels 9 an und das Mitnehmerparallelogramm 1 wird in der geöffneten Stellung gesperrt. Die weitere Öffnungsbewegung und die anschliessende Schliessbewegung der Kabinen- 30 und der gekuppelten Schachttür 43 erfolgen mit gesperrtem Mitnehmerparallelogramm, wodurch Vibrationen und Klappergeräusche bei den Türbewegungen vermieden werden. Am Ende der Schliessbewegung wird die vom Türantrieb 36 mit dem unteren Trum 42.2 über das gesperrte Mitnehmerparallelogramm 1 gemäss Fig. 6 bewegte Kabinentür 30, zusammen mit der Schachttür 43 gezogen, bis sie an einem nicht dargestellten Anschlag ansteht. Dabei läuft die Sperrklinke 23 über die schräge kante 23.1 auf die Stützrolle 21 auf, die Sperrstellung des Mitnehmerparallelogrammes 1 löst sich und bei stillstehender Kabinentür schliesst sich das Mitnehmerparallelogramm durch die Zugkraft des bandförmigen Antriebsmittels 42. Der am Klemmelement 19 angelenkte Betätigungshebel 9 schwenkt vom Anschlag 16 für die offene Stellung des Mitnehmerparallelogrammes 1 zum Anschlag 17 für die geschlossene Stellung des Mitnehmerparallelogrammes 1, die starre und die bewegliche Kurve 2, 3 entfernen sich von der beweglichen und der festen Kupplungrolle 45, 44 der Schachttür 43. Durch die Rückstellbewegung der beweglichen Kupplungsrolle 45 wird die Schachttür verriegelt und der nicht dargestellte Sicherheitskontakt geschlossen. Die zusammendrückbare Auflaufkurve 5 distanziert sich durch die Blattfedern 6 vom starren Kurventräger 4, dabei entfernt sich die Steuerkurve 24 von der Steuerrolle 14 und der Kabinentürriegel 12 bewegt sich in seine horizontale Ruhelage, in der die Kabinentür 30 verriegelt und der Sicherheitskontakt 20 geschlossen ist (Fig. 3). Die Aufzugskabine ist für die Weiterfahrt bereit.With a controlled or an unwanted stop within the door opening zone of a floor, according to FIGS. 5 and 6, the driver parallelogram 1 leads between the fixed and the movable coupling roller 44, 45 of the shaft door 43. The driver parallelogram 1 is spread apart by the tensile force of the tension spring 11 either when the drive motor 37 is de-energized or when the drive motor 37 controlled by a microprocessor is switched over in the opening direction. The clamping element 19 clamped to the belt-shaped drive means 42, together with the drive means 42, executes a pivoting movement through the actuating lever 9 when the cabin door 30 is at a standstill, in which the fixed and the movable curve 2, 3 open in parallel and run onto the coupling rollers 44, 45 of the shaft door . The movable coupling roller 45 is pushed away by a certain distance and the shaft door 43 is unlocked and the movable overrun curve 5 is pressed against the rigid cam carrier 4, the control roller 14 running onto the control curve 24, the car door bolt 12 pressed out of its rest position and the car door 30 unlocked becomes. Depending on the state, the cabin door 30 is either opened by the door drive 36 or can be pushed open by hand. At the beginning of this movement, the pawl 23 rolls on the support roller 21 and, after a few millimeters, tilts downward over the inclined edge 23.1 by the force of the torsion spring 22 until the stop pin 26 for a spring end of the torsion spring 22 abuts the nose 27 of the base plate 10 (Fig. 6). The rear part 23.2 of the pawl 23 is in contact with the chamfer 9.1 of the actuating lever 9 and the driver parallelogram 1 is locked in the open position. The further opening movement and the subsequent closing movement of the cabin door 30 and the coupled shaft door 43 take place with a locked driver parallelogram, as a result of which vibrations and rattling noises during door movements are avoided. At the end of the closing movement, the car door 30 moved by the door drive 36 with the lower run 42.2 via the locked driver parallelogram 1 according to FIG. 6, together with the landing door 43, is pulled until it abuts a stop (not shown). The pawl 23 runs over the inclined edge 23.1 on the support roller 21, the locked position of the driver parallelogram 1 is released and when the cabin door is at a standstill the driver parallelogram closes by the tensile force of the band-shaped drive means 42. The actuating lever 9 articulated on the clamping element 19 swivels from the stop 16 for the open position of the driver parallelogram 1 to stop 17 for the closed position of the driver parallelogram 1, the rigid and the movable curve 2, 3 move away from the movable and the fixed coupling roller 45, 44 of the shaft door 43. The shaft door is locked by the return movement of the movable coupling roller 45 and not shown safety contact closed. The compressible run-up curve 5 is distanced by the leaf springs 6 from the rigid cam carrier 4, the control cam 24 moves away from the control roller 14 and the cabin door latch 12 moves into its horizontal rest position, in which the cabin door 30 is locked and the safety contact 20 is closed (FIG 3). The elevator car is ready to continue.

In den Fig. 1 und 2 ist eine zentral öffnende Zenter-Teleskoptür mit vier Türflügeln dargestellt. Es ist ohne weiteres möglich, mit der erfindungsgemässen Türantriebsvorrichtung jede andere Schiebetürart auszurüsten.1 and 2, a central opening telescopic door with four door leaves is shown. It is easily possible to equip any other type of sliding door with the door drive device according to the invention.

Es wäre ohne weiteres denkbar, anstelle eines bandförmigen Antriebsmittels (42) ein anderes Antriebsmittel, beispielsweise ein Schubkurbeltrieb vorzusehen.It would be readily conceivable to provide another drive means, for example a thrust crank drive, instead of a band-shaped drive means (42).
