Abstract

Locking devices for shaft lift doors having at least one door leaf (1), on which is arranged a door-leaf bolt (9) engaging into a receptacle attached to a further door leaf or to a closing edge (8), prevent an unauthorised opening of the lift doors. However, despite the lock, the door leaf can still be spread open considerably, especially at a door-leaf end distant from the door-leaf bolt. Moreover, if the door-leaf bolt is defective, the locking of the lift doors fails completely. In order to guarantee the locking of the lift doors, even in the event of attempts to open it by force or of a defective door-leaf bolt, there is a second door-leaf bolt (10) which is arranged on the door leaf (1) at a vertical distance from the first door-leaf bolt (9) and which is connected motionally to this via a coupling member (15). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Verriegelungsvorrichtung für eine Schachtaufzugtüre mit mindestens einem Türblatt, an welchem ein Türblattriegel angeordnet ist, der in eine an einem weiteren Türblatt bzw. einer Schließkante angebrachte Aufnahme eingreift. Derartige bekannte Vorrichtungen verhindern ein unbefugtes Öffnen der Aufzugtüren, beispielsweise wenn die Kabine in den Bereichen zwischen einzelnen Etagen steht. Als nachteilig erweist es sich, daß das oder die Türblätter, insbesondere an einem vom Türblattriegel weit entfernten Türblattende trotz der Verriegelung immer noch beträchtlich aufgespreizt werden können. Weiterhin entfällt bei einem defekten Türblattriegel die Verriegelung der Aufzugtüre völlig.The invention relates to a locking device for a shaft elevator door with at least one door leaf, on which a door leaf bolt is arranged, which engages in a receptacle attached to a further door leaf or a closing edge. Such known devices prevent unauthorized opening of the elevator doors, for example when the car is in the areas between individual floors. It proves to be disadvantageous that the door leaf or leaves, in particular at a door leaf end that is far from the door leaf bolt, can still be spread considerably despite the locking. Furthermore, if the door leaf latch is defective, the elevator door is not locked completely.

Die Aufgabe der Erfindung besteht somit darin, eine Vorrichtung der eingangs genannten Art so weiterzubilden, daß die Verriegelung der Aufzugtüre auch bei gewaltsamen Öffnungsversuchen oder einem defekten Türblattriegel gewährleistet ist.The object of the invention is therefore to develop a device of the type mentioned in the introduction so that the locking of the elevator door is ensured even in the event of violent opening attempts or a defective door leaf latch.

Zur Lösung dieser Aufgabe wird erfindungsgemäß ein zweiter Türblattriegel vorgeschlagen, welcher am Türblatt in senkrechtem Abstand vom ersten Türblattriegel angeordnet und mit diesem über ein Kopplungsglied bewegungsmäßig verbunden ist. Bei geschlossener Türe sind nun das bzw. die Türblätter an zwei Stellen verriegelt. Dies erschwert ein Aufspreizen der Türe in erheblichem Maße. Durch die bewegungsmäßige Kopplung der beiden Türblattriegel genügt ein Antrieb für einen Türblattriegel, um beide zu bewegen. Somit kann der Gegenstand der vorliegenden Erfindung problemlos anstelle von bereits bekannten Verriegelungsvorrichtungen angebracht werden. Auch bei einer ungenügenden Verriegelung durch einen defekten Türblattriegel oder eine defekte Aufnahme bleibt die Aufzugtüre aufgrund des zweiten Türblattriegels immer noch geschlossen.To achieve this object, a second door leaf latch is proposed according to the invention, which is arranged on the door leaf at a vertical distance from the first door leaf latch and is movably connected to it via a coupling member. When the door is closed, the door leaf (s) are now locked in two places. This makes it difficult to spread the door open. Due to the movement coupling of the two door leaf latches, one drive for one door leaf latch is sufficient to move both. Thus, the subject matter of the present invention can be easily installed instead of already known locking devices. Even if there is insufficient locking due to a defective door leaf bolt or a defective receptacle, the elevator door still remains closed due to the second door leaf bolt.

Eine besonders bevorzugte Ausführungsform der Erfindung besteht darin, daß der eine Türblattriegel am Türblattoberteil und der andere am Türblattunterteil angeordnet sind. Damit kann Aufspreizversuchen an den Türblattenden besonders erfolgreich begegnet werden. Eine Weiterbildung der Erfindung sieht vor, daß die Türblattriegel als Hakenriegel ausgebildet und am Türblatt schwenkbar gelagert sind und das weitere Türblatt bzw. die Schließkante hintergreifen. Durch diese konstruktive Gestaltung des Türblattriegels kann die Verriegelung der Aufzugtüre in einfacher aber wirksamer Weise erfolgen.A particularly preferred embodiment of the invention consists in that one door leaf latch is arranged on the upper part of the door leaf and the other on the lower part of the door leaf. In this way, attempts to expand the door leaf ends can be countered particularly successfully. A further development of the invention provides that the door leaf latch is designed as a hook bolt and on the door leaf are pivoted and reach behind the other door leaf or the closing edge. This constructive design of the door leaf bolt enables the elevator door to be locked in a simple but effective manner.

Bei einem Ausfall des Antriebs eines Türblattriegels oder bei einem Ausfall des Koppelgliedes muß die Aufzugtüre trotzdem noch verriegelt sein. Deshalb sieht eine weitere Ausgestaltung der Erfindung vor, daß jeder Türblattriegel in Verriegelungsrichtung federbelastet ist, so daß letztere bei Ausfall eines der vorgenannten Teile automatisch in ihre verriegelte Stellung schwenken. Damit die Türe im Notfall auch von außen geöffnet werden kann, sieht eine weitere zweckmäßige Maßnahme vor, daß an der Innenseite des Türblattes ein Betätigungsglied für die Türblattriegel zur Notentriegelung vorgesehen ist. Um eine Verletzung von Personen beim Ein- und Aussteigen in bzw. aus dem Aufzug zu vermeiden, ist es weiterhin sehr vorteilhaft, daß zumindest der am Türblattunterteil angeordnete Türblattriegel in seiner unwirksamen Endstellung vollständig vom Türblatt verdeckt ist. Der Türblattriegel ragt also in der genannten Endstellung nicht über das Türblatt hinaus.In the event of a drive failure of a door leaf bolt or a failure of the coupling link, the elevator door must still be locked. Therefore, a further embodiment of the invention provides that each door leaf latch is spring-loaded in the locking direction, so that the latter automatically pivot into their locked position in the event of failure of one of the aforementioned parts. So that the door can also be opened from the outside in an emergency, a further expedient measure provides that an actuating member for the door leaf latch for emergency unlocking is provided on the inside of the door leaf. In order to avoid injury to persons when getting in and out of the elevator, it is also very advantageous that at least the door leaf bolt arranged on the lower part of the door leaf is completely covered by the door leaf in its inactive end position. The door leaf latch does not protrude beyond the door leaf in the end position mentioned.

Weiterhin besteht zwischen dem oberen Türblattriegel und dem den unteren Türblattriegel betätigenden Koppelglied ein Freilauf. Dieser bewirkt, daß nur Riegelbewegungen, die vom oberen Türblattriegel ausgehen, auf den unteren Türblattriegel übertragen werden, umgekehrt jedoch Riegelbewegungen, die vom unteren Türblattriegel herrühren, den oberen in seiner Stellung nicht beeinflussen. Somit wird dem Fall vorgebeugt, daß durch ein unzulässiges Entriegeln des unteren Türblattriegels von außen her gleichzeitig auch der obere Riegel entriegelt wird und die Tür somit geöffnet werden könnte.Furthermore, there is a freewheel between the upper door leaf latch and the coupling element which actuates the lower door leaf latch. The effect of this is that only bolt movements originating from the upper door leaf latch are transmitted to the lower door leaf latch will, conversely, bolt movements that originate from the lower door leaf latch will not affect the upper position. This prevents the case that an inadmissible unlocking of the lower door leaf bolt from the outside simultaneously unlocks the upper bolt and the door could thus be opened.

A view of an elevator door with a door leaf in the locked position,
Fig. 2
a representation of FIG. 1 in the open position.

Die Aufzugtüre besteht aus einem Türblatt 1, welches mittels zweier Aufhängevorrichtungen 2 mit Rollen 3 und Gegenrollen 4 an einer Führung 5 verschiebbar gelagert ist. Am Türblatt 1 ist eine Verriegelungsvorrichtung 6 angeordnet, welche mit einer an einer Seitenwand 7 des Aufzugs angebrachten Schließkante 8 zusammenwirkt.The elevator door consists of a door leaf 1, which is slidably mounted on a guide 5 by means of two suspension devices 2 with rollers 3 and counter rollers 4. A locking device 6 is arranged on the door leaf 1, which interacts with a closing edge 8 attached to a side wall 7 of the elevator.

Die Verriegelungsvorrichtung 6 weist einen oberen 9 und einen unteren Türblattriegel 10 auf. Der obere Türblattriegel 9 befindet sich am Oberteil 11 des Türblatts 1, während der untere Türblattriegel 10 am Unterteil 12 desselben angeordnet ist. Beide Türblattriegel 9, 10 sind als Hakenriegel ausgebildet, an Drehpunkten 13, 14 schwenkbar gelagert und hintergreifen bei geschlossener Aufzugtüre die Schließkante 8. Über ein Koppelglied 15 sind beide Türblattriegel 9, 10 bewegungsmäßig miteinander verbunden. Zwischen Koppelglied 15 und oberem Türblattriegel 9 befindet sich zusätzlich ein Freilauf 23, der die Bewegung des oberen Türblattriegels 9 auf den unteren Türblattriegel 10 überträgt, eine Bewegung des unteren Türblattriegels 10 jedoch nicht auf den oberen Türblattriegel 9 überträgt. Für die beiden Türblattriegel 9, 10 ist zur Notentrieglung ein Betätigungsglied 16 vorgesehen, welches an dem Türblatt 1 angeordnet ist und über ein am oberen Türblattriegel 9 befestigtes Zugglied 17 durch Drehen in Pfeilrichtung 18 entriegelt. Um bei einem Ausfall des Kopplungsgliedes 15 die Entrieglung trotzdem zu gewährleisten, ist der untere Türblattriegel 10 in Entriegelungsrichtung 20 federbelastet 22. Wie aus Fig. 2 ersichtlich, kann der untere Türblattriegel 10 so weit verschwenkt werden, daß er in seiner unwirksamen Endstellung vollständig vom Türblatt 1 verdeckt ist. Beim Ein- und Aussteigen von Personen in bzw. aus dem Aufzug kann somit niemand an dem unteren Türblattriegel 10 hängen bleiben, wodurch Verletzungen der Personen oder Beschädigung von Kleidung vermieden werden.The locking device 6 has an upper 9 and a lower door leaf latch 10. The upper door leaf latch 9 is located on the upper part 11 of the door leaf 1, while the lower door leaf latch 10 is arranged on the lower part 12 thereof. Both door leaf latches 9, 10 are designed as hook bolts, are pivotably mounted at pivot points 13, 14 and engage behind the closing edge 8 when the elevator door is closed. Both door leaf bolts 9, 10 are connected to one another in terms of movement via a coupling member 15. Between the coupling member 15 and the upper door leaf bolt 9 there is an additional freewheel 23 which transmits the movement of the upper door leaf bolt 9 to the lower door leaf bolt 10, but does not transmit a movement of the lower door leaf bolt 10 to the upper door leaf bolt 9. For the two door leaf latches 9, 10, an actuating member 16 is provided for emergency unlocking, which is arranged on the door leaf 1 and unlocked by means of a tension member 17 fastened to the upper door leaf latch 9 by turning in the direction of the arrow 18. In order to ensure the unlocking in the event of a failure of the coupling member 15, the lower door leaf latch 10 is spring-loaded in the unlocking direction 20 1 is covered. When people get in and out of the elevator, nobody can get caught on the lower door leaf latch 10, which prevents injuries to people or damage to clothing.

Zur Entriegelung der Aufzugtüre wird der obere Türblattriegel 9 mittels eines nicht näher dargestellten Antriebs in Entriegelungsrichtung 19 verschwenkt. Dadurch erfolgt über den Freilauf 23 und das Koppelglied 15 gleichzeitig die Entriegelung des unteren Turblattriegels 10 in Entriegelungsrichtung 20. Zur Verriegelung der Aufzugtüre erfolgt die Verschwenkung der beiden Türblattriegel 9, 10 entgegen der Entriegelungsrichtung 19, 20. Die Aufzugtüre ist dann an zwei Stellen verriegelt, so daß ein Aufspreizen des Türblatts 1 erheblich erschwert wird. Bei Ausfall eines Türblattriegels bleibt die Türe auf Grund des zweiten Türblattriegels immer noch geschlossen. Damit ist eine recht sichere Verriegelung der Aufzugtüre gewährleistet.To unlock the elevator door, the upper door leaf bolt 9 is pivoted in the unlocking direction 19 by means of a drive (not shown in more detail). As a result, the lower one is unlocked simultaneously via the freewheel 23 and the coupling member 15 Door leaf bolt 10 in the unlocking direction 20. To lock the elevator door, the two door leaf bolts 9, 10 are pivoted counter to the unlocking direction 19, 20. The elevator door is then locked in two places, so that spreading open the door leaf 1 is made considerably more difficult. If a door leaf latch fails, the door still remains closed due to the second door leaf latch. This ensures a fairly secure locking of the elevator door.
