Description

Die Erfindung geht aus von einer Ver- und Entriegelungsvorrichtung für Türen von Aufzugsanlagen nach dem Oberbegriff des ersten Anspruches.The invention relates to a locking and unlocking device for doors of elevator systems according to the generic term of the first Claim.

Für Aufzugsanlagen bestehen verschiedene Sicherheitsvorschriften um einen sicheren Personen- und Warentransport in den Aufzugsanlagen zu gewährleisten. So sind moderne Aufzugsanlagen mit einer Kabinentüre versehen, die die Aufzugskabine gegen den Schacht und gegenüber den Schachttüren abschliesst. Die Aufzugskabinentüre sowie die Schachttüren können zur Gewährleistung der Sicherheit von Passagiere sowie transportierten Waren nur geöffnet werden, wenn der Aufzug sich auf einem entsprechenden Halteniveau befindet in einem vorgegebenen Bereich an einer Schachttüre. Der Aufzug kann auch nur in Bewegung gesetzt werden, wenn die Schachttüren und die Kabinentüre geschlossen und verriegelt sind. Die Ver- bzw. Entriegelung der Schachttüren und der Kabinentüre erfolgt üblicherweise mittels separaten Einrichtungen. Für Schachttüren ist z.B. eine Entriegelungskurve an der Kabine montiert, die mit einer an der Schachttüre angeordneten Rolle zur Schachttürverriegelung zusammenwirkt, um die Schachttüre zu entriegeln. Zur Kabinentürzuhaltung bzw. zu deren Entriegelung sind von einem Kabinentürantrieb betätigte mechanische Einrichtungen und elektromagnetische Einrichtungen bekannt.There are various safety regulations for elevator systems for a safe transport of persons and goods into the To ensure elevator facilities. Such are modern elevator systems provided with a car door, the elevator car against the Schacht and opposite the shaft doors closes. The Elevator car door and the shaft doors can to Ensuring the safety of passengers as well as transported Goods only open when the elevator is on one corresponding holding level is in a predetermined range at a shaft door. The elevator can only set in motion when the landing doors and the car door are closed and closed are locked. The locking and unlocking of the landing doors and The car door is usually done by means of separate Institutions. For landing doors, e.g. a unlocking curve mounted on the cabin, with one at the shaft door arranged roller to the shaft door lock cooperates to unlock the shaft door. To the cabin door lock or to their unlocking are actuated by a car door drive mechanical devices and electromagnetic devices known.

Aus der DE-OS-2 411 138 ist eine mechanische Ver- und Entriegelungs-vorrichtung für Türen an Aufzugsanlagen bekannt. Dort sind für die Kabinentüre sowie für die Schachttüren jeweils separate elektromagnetisch arbeitende Türentriegelungen bzw. Türverriegelungen vorhanden. Die Türentriegelungsvorrichtung besteht im wesentlichen aus einem Elektromagneten, einem Verriegelungsbolzen und einer Druckfeder. Der Verriegelungsbolzen ist verschiebbar angeordnet und dient gleichzeitig als Anker einer Magnetspule des Elektromagneten. Die Druckfeder drückt den Verriegelungsbolzen in die Verriegelungsstellung, beim Anlegen eines elektrischen Stromes an die Magnetspule zieht die so erzeugte elektromagnetische Kraft den Bolzen gegen die Kraft der Druckfeder und löst die Verriegelung. Stoppt nun die Kabine der Aufzugsanlage bei einer Schachttüre, werden über Schalter die Türentriegelungsvorrichtung der Schachttüre sowie die Türentriegelungsvorrichtung der Kabine mit elektrischem Strom versorgt und somit die Verriegelungsbolzen bewegt und die Türen freigegeben. Bei einem Stromausfall werden die Türen mittels der Druckfedern und der Verriegelungsbolzen jeweils verriegelt. Nachteil einer solchen Lösung ist, dass an jeder Schachttüre und an der Kabinentür eine elektromagnetisch betriebene Türentriegelungsvorrichtung angeordnet werden muss und die Türentriegelungsvorrichtungen jeweils separat angesteuert werden müssen.From DE-OS-2,411,138 is a mechanical Ver and Unlocking device for doors on elevator systems known. There are for the cabin door as well as for the landing doors respectively separate electromagnetically operating door unlockings or Door locks available. The door unlocking device consists essentially of an electromagnet, a Locking bolt and a compression spring. The locking bolt is slidably arranged and serves as an anchor of a Magnetic coil of the electromagnet. The compression spring presses the Locking bolt in the locking position when applying an electric current to the solenoid pulls the sun Electromagnetic force generated the bolt against the force of Compression spring and releases the lock. Now stop the cabin of the Elevator installation at a shaft door, the switch over the Door unlocking device of the shaft door and the Door unlocking device of the cabin with electric current supplied and thus moves the locking bolts and the doors Approved. In case of power failure, the doors are opened by means of Compression springs and the locking bolt locked respectively. Disadvantage of such a solution is that at each shaft door and on the cabin door an electromagnetically operated Door unlocking device must be arranged and the Door unlocking devices are each controlled separately have to.

Der Erfindung liegt die Aufgabe zugrunde, für eine Ver- und Entriegelungsvorrichtung für Türen von Aufzugsanlagen der eingangs genannten Art eine einfache, sichere und kostengünstige Vorrichtung zur Ent- und Verriegelung von Kabinentüren und Schachttüren anzugeben.The invention is based on the object for a United and Unlocking device for doors of elevator systems of the beginning mentioned type a simple, safe and inexpensive Device for unlocking and locking cabin doors and Indicate landing doors.

Erfindungsgemäss wird dies durch eine Ver- und Entriegelungsvorrichtung mit den Merkmalen des ersten Anspruches erreicht.According to the invention this is by a United and Unlocking device with the features of the first claim reached.

Wesentlich ist, dass mittels einer an der Aufzugskabine angeordneten Betätigungseinrichtung von der Aufzugskabine aus ein Mittel zur Ver- und Entriegelung der Schachttür und ein Mittel zur Ver- und Entriegelung der Kabinentür betätigbar sind.It is essential that by means of an elevator car arranged actuator from the elevator car from a Means for locking and unlocking the landing door and a means for Locking and unlocking of the car door can be actuated.

Die Betätigungseinrichtung umfasst ein bewegbares Teil, das mit dem Mittel zur Ver- und Entriegelung der Kabinentür derart verbunden ist, dass das Mittel zur Ver- und Entriegelung der Kabinentür bei einer Bewegung des bewegbaren Teils zwischen einer Verriegelungs- und einer Entriegelungsstellung bewegbar ist. The actuating device comprises a movable part, which with the means for locking and unlocking the car door in such a way connected, that the means for locking and unlocking the Cabin door during a movement of the movable part between a Locking and unlocking position is movable.

Das Mittel zur Ver- und Entriegelung der Schachttür ist derart angeordnet, dass das bewegbare Teil mit dem Mittel zur Ver- und Entriegelung der Schachttür in Kontakt bringbar ist, um das Mittel zur Ver- und Entriegelung der Schachttür zu betätigen, wenn sich die Aufzugskabine in einem vorgegebenen Bereich an der Schachttür befindet.The means for locking and unlocking the shaft door is such arranged that the movable part with the means for supply and Unlocking the landing door is brought into contact with the agent to lock and unlock the landing door to operate when the elevator car in a predetermined area at the shaft door located.

Die Vorteile der Erfindung sind unter anderem darin zu sehen, dass durch die Betätigungseinrichtung gleichzeitig die Schachttüren und die Kabinentür ver- bzw. entriegelt werden können. Durch die kombinierte Ver- und Entriegelungsvorrichtung können somit Kosten gegenüber bisher bekannten Ver- und Entriegelungsvorrichtungen eingespart werden, da nur eine Betätigungseinrichtungauf der Aufzugskabine zur Ent- und Verriegelung der Schachttüren und der Kabinentür benötigt wird. Ein weiterer Vorteil ist der sehr geringe Platzbedarf, der die Betätigung der Ver- und Entriegelungsvorrichtung selbst bei extrem schmalem Abstand der Kabine zur Schachtwand respektive zur Schachttüre ermöglicht.The advantages of the invention can be seen inter alia in that by the actuator at the same time the shaft doors and the cabin door can be locked or unlocked.

Auch entstehen im Normalbetrieb nur wenige Geräusche bei der Entriegelung der Schachttüren, da die Betätigungseinrichtung erst beim Entriegelungsvorgang in Kontakt mit dem Mittel zur Ver- und Entriegelung der Schachttür treten.Another advantage is that the control of the supply and Unlocking device is simple, since only one Actuating device must be operated to unlock the door. Also arise in normal operation, only a few sounds in the Unlocking the shaft doors, as the actuator only during unlocking in contact with the means for supply and Unlocking the landing door.

Die Betätigungseinrichtung kann elektrisch ansteuerbar sein. Sie ist so ausgelegt, dass die Schachttüren selbst bei einem Stromausfall geöffnet werden können, wenn sich die Kabine auf einem Halteniveau in einem vorgegebenen Bereich der Schachttür befindet und die Betätigungseinrichtung eine Position einnimmt, in der die Betätigungseinrichtung mit dem Mittel zur Ver- und Entriegelung der Schachttür in Kontakt bringbar ist. Die Kabinentür ihrerseits wird auch entriegelt, wenn die Betätigungseinrichtung die Schachttür entriegelt. The actuating device can be electrically controlled. she is designed so that the shaft doors themselves at a Power outage can be opened when the cab is on a holding level in a predetermined area of the shaft door located and the actuator occupies a position, in which the actuator with the means for supply and Unlocking the shaft door can be brought into contact. The Cabin door in turn is also unlocked when the Actuator unlocks the shaft door.

Ein stationäres Mittel ist derart angeordnet ist, dass es einen Bewegungsspielraum des bewegbaren Teils derart limitiert, dass das Mittel zur Ver- und Entriegelung der Kabinentür nicht mittels einer Bewegung des bewegbaren Teils in die Entriegelungsstellung bringbar ist, wenn sich die Aufzugskabine ausserhalb eines vorgegebenen Bereiches an der Schachttür befindet. Somit wird verhindert, dass bei Stromausfall die Passagiere die Kabinentüre öffnen können, wenn sich die Kabine nicht auf einem Halteniveau an einer Schachttüre befindet.A stationary means is arranged such that it has a Movement of the movable part limited so that the Means for locking and unlocking the car door not means a movement of the movable part in the unlocked position can be brought when the elevator car outside a predetermined area is located on the shaft door. Thus, will prevents passengers in case of power failure, the car door when the cabin is not at a hold level a shaft door is located.

Das genannte stationäre Mittel kann eine Schachtwand oder eine an einer Schachtwand geeignet angeordnete Vorrichtung sein.Said stationary means may be a shaft wall or an a well wall appropriately arranged device be.

Zweckmässigerweise ist die Betätigungseinrichtung eine elektromagnetische Vorrichtung. Dabei kann auf bewährte und betiebssichere Elektromagneten zurückgegriffen werden. Eine solche elektromagnetisch betriebene Vorrichtung ist einfach anzusteuern und kann klein gebaut sein. Anstelle eines Elektromagneten können auch pneumatisch oder hydraulisch arbeitende Vorrichtungen vorgesehen sein. Letztere können jeweils elektrisch ansteuerbar sein. Grundsätzlich ist aus Gründen der Betriebssicherheit und zum Schutz von in der Aufzugkabine beförderten Personen ein Energiespeicher vorgesehen, welcher bei Ausfall der Energieversorgung die Ver- und Entriegelungseinrichtung in einer Weise ansteuert bzw. betätigt, dass die Kabinen- und Schachttüre freigegeben und gegebenenfalls in der Aufzugkabine eingeschlossene Passagiere befreit werden können.Conveniently, the actuating device is a electromagnetic device. It can be on proven and non-intrusive electromagnets are used. Such Electromagnetically operated device is easy to control and can be small in size.

This guide is designed as a curved slot so that during a movement of the anchor bolt 6 of the locking pin 10th is reciprocated perpendicular to the anchor bolt 6. Thus, when the anchor bolt 6 by means of the spring 7 or another Power accumulator is pressed against the release lever 12, the Locking pin 10 is brought into the unlocked position and the car door 11 released. If the electromagnet 5 by the not shown control again with electric current acted upon, the anchor bolt 6 moves against the Spring force of the spring 7 and presses the pin 10 in the Locking position and blocks the car door 11th

    Bei einem Defekt des Elektromagneten 5 oder bei einem Stromausfall wird der Ankerbolzen 6 mittels der Feder 7 in Richtung der Schachtwand 4 gedrückt.In case of a defect of the electromagnet 5 or in the event of a power failure is the anchor bolt 6 by means of the spring 7 in the direction of Shaft wall 4 pressed.

    Die Distanz zwischen der Schachtwand und der Betätigungseinrichtung ist im vorliegenden Beispiel derart gewählt, dass die Kabinentür nicht entriegelt wird, wenn die Rolle 8 in Richtung der Schachtwand bewegt wird, bis sie die Schachtwand berührt. Der Hub, der durch diese Bewegung erzeugt wird, reicht nicht aus, um die Kabinentür 11 mittels des Verriegelungszapfen 10 zu entriegeln. Sich in der Kabine befindende Passagiere können somit die Kabinentüre nicht öffnen. Wird nun die Kabine mittels Hilfsmotoren oder andern Hilfsmitteln auf die Höhe einer Schachttüre 13 gebracht, rollt die Rolle 8 an der Schachtwand entlang, bis sie in die Schachttürentriegelung 9 eingreifen kann und die Schachttüre 13 freigibt. Gleichzeitig wird dann auch die Kabinentüre 11 freigegeben, da nun der Hub der Rolle 8 und somit des Verriegelungszapfen 10 gross genug ist, um die Kabinentüre 11 freizugeben.The distance between the shaft wall and the Actuator is in the present example such chosen that the cabin door will not unlock when the Roller 8 is moved in the direction of the shaft wall until it reaches the Shaft wall touched. The hub that generates by this movement is not sufficient to the cabin door 11 by means of Locking pin 10 to unlock. Yourself in the cabin Passengers located can thus not open the car door. Will now the cabin by means of auxiliary motors or other aids brought to the height of a shaft door 13, the roller 8 rolls along the shaft wall until it enters the shaft door release 9 can intervene and the shaft door 13 releases. At the same time then the car door 11 released, since now the hub of the role 8 and thus the locking pin 10 is large enough to the Cab door 11 release.

    Selbstverständlich ist die Erfindung nicht auf das gezeigte und beschriebene Ausführungsbeispiel beschränkt.Of course, the invention is not limited to that shown and described embodiment limited.

    Die Rolle 8 und der Verriegelungszapfen 10 können bezüglich ihrer Position auf den Haltevorrichtungen 15, 18 auch gegenseitig ausgetauscht werden, wenn die Ver- und Entriegelungsvorrichtung entsprechend anders eingebaut werden muss.The roller 8 and the locking pin 10 can with respect to their Position on the holding devices 15, 18 and each other be replaced when the locking and unlocking device must be installed according to different.

    Die Rolle 8 zur Betätigung der Schachttürentriegelung kann auch mittels einer Entriegelungskurve betätigt werden.The roller 8 for actuating the shaft door unlocking can also be operated by means of a release curve.

    Um den Bewegungsspielraum der Rolle 8 derart zu limitieren, dass der Verriegelungszapfen 10 bei einer mittels der Betätigungseinrichtung erzeugten Bewegung der Rolle 8 nicht in die Entriegelungsstellung bringbar ist, wenn sich die Aufzugskabine (2) ausserhalb eines vorgegebenen Bereiches an der Schachttür befindet, kann - abweichend von dem in den Fig. 1 und 2 dargestellten Beispiel - anstelle der Schachtwand auch jedes andere in der Aufzugsanlage stationär angeordnete Mittel verwendet werden, das eine geeignete Distanz bezüglich der Betätigungseinrichtung aufweist.In order to limit the range of motion of the roller 8 such that the locking pin 10 at a means of Actuator generated movement of the roller 8 is not in the Unlocking position can be brought when the elevator car (2) outside a predetermined area at the shaft door - may differ from that in Figs. 1 and 2 example shown - instead of the shaft wall also each other means stationarily arranged in the elevator installation are used be that a suitable distance with respect to the Actuating device comprises.

    Anstelle der Rolle 8 kann auch ein anderes mittels der Betätigungseinrichtung bewegbares Teil verwendet werden. Da ein solches Teil mit der Schachtwand in Berührung kommen kann, sollte es bevorzugt so ausgebildet sein, dass es gegebenenfalls möglichst verschleissarm längs der Schachtwand bewegt werden kann. Geeignet erscheint beispielsweise auch ein Gleitelement, das verschleissarm längs der Schachtwand gleiten kann.Instead of the roller 8 can also be another means of Actuator movable part can be used. There a such part should come into contact with the manhole wall it preferably be designed so that it possibly as possible wear-resistant along the shaft wall can be moved. Suitable For example, also appears a sliding element, the wear with little wear along the shaft wall.

    Anstelle des Verriegelungszapfen 10 kann auch ein anderes Mittel zur Ver- und Entriegelung der Kabinentür verwendet werden, das mit der Betätigungseinrichtung kompatibel ist. Anstelle der Schachttürentriegelungsvorrichtung 9 kann auch ein anderes geeignetes Mittel (12) zur Ver- und Entriegelung der Schachttür verwendet werden, das mit der Betätigungseinrichtung kompatibel ist.Instead of the locking pin 10 may also be another means be used for locking and unlocking the car door, with the actuator is compatible. Instead of Shaft door unlocking device 9 may also be another suitable means (12) for locking and unlocking the shaft door used, compatible with the actuator is.
