Description

Die Erfindung betrifft eine Stopeinrichtung zum Verhindern von Drift einer auf einem Stockwerk stehenden Aufzugskabine mit Kabinentüren.The invention relates to a stop device for preventing drift of an elevator car standing on a floor with car doors.

Aus der Schrift EP-A1-0 578 238 ist eine Stopeinrichtung für Hydraulikaufzüge bekannt geworden, mit der Abwärtsdrift einer Aufzugskabine vermieden wird. Drehbar am Tragrahmen der Aufzugskabine angeordnete Klinken werden bei einem Stockwerkhalt mittels eines Magneten ausgeschwenkt. An der Schachtwand angeordnete Stopblocks ragen in die Bahnen der ausgeschwenkten Klinken, sodass bei Abwärtsdrift der Aufzugskabine die Klinken auf den Stopblocks aufliegen und die unerlaubte Kabinenbewegung stoppen.From the document EP-A1-0 578 238 a stop device for hydraulic elevators has become known, with which downward drift of an elevator car is avoided. Pawls rotatably arranged on the support frame of the elevator car are pivoted out by means of a magnet when a floor is held. Stop blocks arranged on the shaft wall protrude into the path of the pivoted pawls, so that when the elevator car drifts downwards, the pawls rest on the stop blocks and stop the unauthorized car movement.

Ein Nachteil der bekannten Einrichtung liegt darin, dass die Klinken über ein kompliziertes Gestänge magnetisch aus- und eingeschwenkt werden. Die Zuverlässigkeit der als Sicherheitseinrichtung vorgesehenen Stopeinrichtung wird dadurch beeinträchtigt. Bei kleinen Kabinenlasten besteht die Gefahr der Aufwärtsdrift der Aufzugskabine. Aufwärtsdrift kann mit der bekannten Einrichtung nicht vermieden werden.A disadvantage of the known device is that the pawls are magnetically swung out and in via a complicated linkage. This affects the reliability of the stop device provided as a safety device. With small car loads there is a risk of the elevator car drifting upwards. Upward drift cannot be avoided with the known device.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, die Nachteile der bekannten Einrichtung zu vermeiden und eine Stopeinrichtung zu schaffen, die den Sicherheitsvorschriften bezüglich unerlaubter Kabinenbewegungen auf dem Stockwerk genügen.The invention seeks to remedy this. The invention, as characterized in the claims, achieves the object of avoiding the disadvantages of the known device and of providing a stopping device which meets the safety regulations relating to unauthorized car movements on the floor.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass mit einfachsten Mitteln die Aufzugskabine gegen Drift geschützt wird. Ausserdem ist gewährleistet, dass die erfindungsgemässe Stopeinrichtung immer dann eingeschaltet ist, wenn die Kabinentüren offen stehen und unmittelbar eine Gefahr für die Aufzugsbenutzer besteht. Weiter kann die Stopeinrichtung gleichzeitig der Kabinentürverriegelung dienen, wenn sich die Kabine ausserhalb eines Stockwerkhalts befindet.The advantages achieved by the invention can essentially be seen in the fact that the elevator car is protected against drift with the simplest means. In addition, it is ensured that the stop device according to the invention is always switched on when the car doors are open and there is a direct danger to the elevator users. Furthermore, the stop device can simultaneously serve to lock the car door when the car is outside a floor.

In den Fig. 1 bis 6 ist mit 1 eine Aufzugskabine mit einer aus mindestens einem Kabinentürflügel 2 bestehenden Kabinentür und einer Kabinentürschwelle 3 bezeichnet. Die Aufzugskabine 1 steht auf einem Stockwerk 4 und wird von einer an der Kabinentürschwelle 3 angeordneten Stopeinrichtung 5 gegen Drift in Aufwärtsrichtung und in Abwärtsrichtung gesichert. Beim Öffnen der Kabinentür wird die Stopeinrichtung 5 mittels des Kabinentürflügels 3 in die in Fig. 1 gezeigte Stellung geschwenkt. Mit der Kabinentür wird auch eine aus mindestens einem Stockwerktürflügel 6 bestehende Stockwerktür geöffnet. Beim Öffnungs- und Schliessvorgang der Kabinentür bzw. der Stockwerktür wird der Kabinentürflügel 2 an der Kabinentürschwelle 3 bzw. der Stockwerktürflügel 6 an einem in den Fig. 1 bis 5 als Stockwerktürschwelle 7 ausgebildeten Schachtelement geführt bewegt. Die Stockwerktürschwelle 7 ragt in einen durch eine Schachtwand 8 begrenzten Aufzugsschacht 9, in dem die Aufzugskabine 1 verfahren wird und stellt eine Fortsetzung der Stockwerksbodenplatte dar.1 to 6, 1 denotes an elevator car with a car door consisting of at least one car door leaf 2 and a car door sill 3. The elevator car 1 stands on a floor 4 and is secured against drift in the upward and downward direction by a stop device 5 arranged on the car door sill 3. When the car door is opened, the stop device 5 is pivoted into the position shown in FIG. 1 by means of the car door leaf 3. With the cabin door, a floor door consisting of at least one floor door leaf 6 is also opened. During the opening and closing process of the car door or the landing door, the cabin door leaf 2 is moved in a guided manner on the shaft door sill 3 or the floor door leaf 6 on a shaft element designed as a floor door sill 7 in FIGS. 1 to 5. The floor door sill 7 projects into an elevator shaft 9, delimited by a shaft wall 8, in which the elevator car 1 is moved and represents a continuation of the floor slab.

Wie in den Fig. 2 und 3 gezeigt besteht die Stopeinrichtung 5 aus einer die Kabinentürschwelle 3 durchdringenden Drehachse 10, aus einem ersten Lastarm 11, aus einem zweiten Lastarm 12 und aus einem Betätigungsarm 13. Der erste Lastarm 11 ist am unteren Ende und der zweite Lastarm 12 ist am oberen Ende der Drehachse 13 derart angeordnet, dass diese bei Bündigstellung der Kabinentürschwelle 3 mit der Stockwerktürschwelle 7 mittels der Drehachse 10 frei schwenkbar sind. Bei geschlossener Kabinentür ragt der am oberen Ende der Drehachse 10 angeordnete Betätigungsarm 13 mit einer türseitigen Betätigungsnocke 14 in die Bahn des Kabinentürflügels 2. Anstelle der Betätigungsnocke 14 kann auch ein Betätigungsrad angeordnet sein, das an der Oberfläche des Kabinentürflügels 2 abrollt. Beim Öffnungsvorgang schwenkt der Kabinentürflügel 2 mittels des Betätigungsarmes 13 und der Betätigungsnocke 14 die Lastarme 11, 12 in die in Fig. 1 und 3 gezeigte Arbeitsstellung aus, in der die Lastarme 11, 12 die Stockwerktürschwelle 7 in horizontaler Richtung überragen und dabei die Aufzugskabine 1 gegen Drift in Aufwärtsrichtung und in Abwärtsrichtung sichern. Bei Drift in Abwärtsrichtung wird der oberhalb der Stockwerktürschwelle 7 liegende zweite Lastarm 12 maximal mit dem Gewicht der Aufzugskabine 1 und der Kabinenlast belastet. Bei Drift in Aufwärtsrichtung wird der unterhalb der Stockwerktürschwelle 7 liegende erste Lastarm 11 bei ausgeschaltetem Antrieb maximal mit der halben Kabinenlast belastet.As shown in FIGS. 2 and 3, the stop device 5 consists of an axis of rotation 10 penetrating the cabin door sill 3, a first load arm 11, a second load arm 12 and an actuating arm 13. The first load arm 11 is at the lower end and the second The load arm 12 is arranged at the upper end of the axis of rotation 13 in such a way that when the cabin door sill 3 is flush with the floor door sill 7, these can be freely pivoted by means of the axis of rotation 10. When the cabin door is closed, the actuating arm 13 arranged at the upper end of the axis of rotation 10 projects into the path of the cabin door leaf 2 with an actuating cam 14 on the door side. Instead of the actuating cam 14, an actuating wheel can also be arranged that rolls on the surface of the cabin door leaf 2. During the opening process, the cabin door leaf 2 pivots by means of the actuating arm 13 and the actuating cam 14 Load arms 11, 12 into the working position shown in FIGS. 1 and 3, in which the load arms 11, 12 project above the landing door sill 7 in the horizontal direction and thereby secure the elevator car 1 against drift in the upward and downward directions. In the event of a drift in the downward direction, the second load arm 12 located above the landing door threshold 7 is loaded to a maximum by the weight of the elevator car 1 and the car load. If there is a drift in the upward direction, the first load arm 11 below the floor door sill 7 is loaded with a maximum of half the cabin load when the drive is switched off.

Beim Schliessen der Kabinentür wird die Stopeinrichtung 5 mittels einer Rückstellfeder 15 in die Ruhestellung eingeschwenkt, sodass die Aufzugskabine 1 im Aufzugsschacht 9 ungehindert verfahrbar ist. Die Rückstellfeder 15 kann eine wie in Fig. 2 gezeigt an der Kabinentürschwelle 3 und am zweiten Lastarm 12 angeordnete Zugfeder oder wie in Fig. 3 gezeigt je eine oberhalb und unterhalb der Kabinentürschwelle 3 angeordnete die Drehachse 10 umschlingende Spiralfeder sein, wobei diese zwischen der Kabinentürschwelle 3 und einem Anschlag 16 eingespannt ist. Die Drehposition der Stopeinrichtung 5 wird von einem Bewegungssensor 17 überwacht, dessen Signale an die Aufzugssteuerung weitergeleitet wird.When the car door is closed, the stop device 5 is pivoted into the rest position by means of a return spring 15, so that the elevator car 1 can be moved freely in the elevator shaft 9. The return spring 15 can be a tension spring arranged on the car door sill 3 and on the second load arm 12 as shown in FIG. 2 or, as shown in FIG. 3, in each case a spiral spring arranged above and below the car door sill 3 and wrapping around the axis of rotation 10, this being between the car door sill 3 and a stop 16 is clamped. The rotational position of the stop device 5 is monitored by a motion sensor 17, the signals of which are forwarded to the elevator control.

Bei der in Fig. 4 und 5 gezeigten Ausführungsvariante besteht die Stopeinrichtung 5 aus dem Betätigungsarm 13 und aus dem zweiten Lastarm 12, der mittels eines zweiten Auslenkarmes 18 mit dem Betätigungsarm 13 und der Drehachse 10 verbunden ist. Der auf der Unterseite der Kabinentürschwelle 3 liegende nicht sichtbare erste Lastarm 11 ist mittels eines ersten Auslenkarmes mit der Drehachse 10 verbunden, sodass beim Betätigen des Betätigungsarmes 13 durch den Kabinentürflügel 2 beide Lastarme 11, 12 in horizontaler Richtung verschwenkt werden und die Stockwerktürschwelle 7 überragen.In the embodiment variant shown in FIGS. 4 and 5, the stop device 5 consists of the actuating arm 13 and of the second load arm 12, which is connected to the actuating arm 13 and the axis of rotation 10 by means of a second deflecting arm 18. The invisible first load arm 11 lying on the underside of the car door sill 3 is connected to the axis of rotation 10 by means of a first deflecting arm, so that when the actuating arm 13 is actuated by the car door leaf 2, both load arms 11, 12 are pivoted in the horizontal direction and protrude above the storey door sill 7.

Fig. 6 zeigt eine Anordnungsvariante der erfindungsgemässen Stopeinrichtung 5, die seitlich der Aufzugskabine 1 an einer Kabinenplattform 19 angeordnet ist und im gezeigten eingeschalteten Zustand mit den Lastarmen 11, 12 in ein als Nische 20 ausgebildetes an der Schachtwand 8 angeordnetes Schachtelement eintaucht. Diese Anordnungsvariante eignet sich besonders für mehrflügelige Teleskoptüren, die im Türschwellenbereich in der Tiefe mehr Platz beanspruchen. Anstelle der Nische 20 kann auch ein an der Schachtwand 8 angeordneter in den Aufzugsschacht 9 ragender Bügel vorgesehen werden, der im eingeschalteten Zustand der Stopeinrichtung 5 oberhalb und unterhalb von den Lastarmen 11, 12 in horizontaler Richtung überragt wird.6 shows a variant of the arrangement of the stop device 5 according to the invention, which is arranged on the side of the elevator car 1 on a car platform 19 and, in the switched-on state shown, dips with the load arms 11, 12 into a shaft element arranged as a recess 20 on the shaft wall 8. This arrangement variant is particularly suitable for multi-leaf telescopic doors that require more space in the door sill area. Instead of the niche 20, a bracket arranged on the shaft wall 8 and projecting into the elevator shaft 9 can be provided, which in the switched-on state of the stop device 5 is towered above and below by the load arms 11, 12 in the horizontal direction.

In den Fig. 1 bis 6 ist die erfindungsgemässe Stopeinrichtung 5 an der Kabinentürschwelle 3 so angeordnet, dass die Stopeinrichtung 5 am Ende des Öffnungsvorganges der Kabinentür, also kurz vor der Offenstellung des Kabinentürflügels 2 eingeschaltet wird.1 to 6, the stop device 5 according to the invention is arranged on the car door sill 3 in such a way that the stop device 5 is switched on at the end of the opening process of the car door, that is to say shortly before the car door leaf 2 is opened.

In einer vierten Ausführungsvariante dient die Stopeinrichtung 5 gleichzeitig zur Türverriegelung. Sie ist entsprechend dem ersten Ausführungsbeispiel ausgebildet, jedoch an der Kabinentürschwelle 3 so angeordnet, dass die Stopeinrichtung 5 bereits am Anfang des Öffnungsvorganges der Kabinentür, also kurz nach dem Beginn der Öffnungsbewegung des Kabinentürflügels 2 betätigt wird. Unterhalb der Stockwerktürschwelle 7 ist eine Nische angeordnet, in die der in dieser Ausführungsvariante vorzugsweise verlängerte erste Lastarm 11 im eingeschalteten Zustand der Stopeinrichtung 5 eintaucht. Beim weiteren Öffnen rollt das Betätigungsrad 14 des Betätigungsarmes 13 an der Kabinentürfront ab.In a fourth embodiment variant, the stop device 5 also serves to lock the door. It is designed in accordance with the first exemplary embodiment, but is arranged on the car door sill 3 in such a way that the stop device 5 is actuated at the beginning of the opening process of the car door, ie shortly after the opening movement of the car door leaf 2 begins. A niche is arranged below the floor door sill 7, into which the first load arm 11, which is preferably extended in this embodiment variant, is immersed when the stop device 5 is switched on. When opened further, the actuating wheel 14 of the actuating arm 13 rolls off the front of the cabin door.

Beim Schliessvorgang rollt das Betätigungsrad 14 wiederum auf der Kabinentürfront ab, bis der Betätigungsarm 13 an der der Türschliesskante gegenüberliegenden Türkante einschwenkt und die Stopeinrichtung 5 ausschaltet. Dabei wird der erste Lastarm 11 aus der Nische in die Ruhestellung geschwenkt, in der die Aufzugskabine 1 im Aufzugsschacht 9 frei verfahrbar ist.During the closing process, the actuating wheel 14 rolls again on the front of the cabin door until the actuating arm 13 swings in on the door edge opposite the door closing edge and switches off the stop device 5. The first load arm 11 is pivoted out of the niche into the rest position, in which the elevator car 1 can be moved freely in the elevator shaft 9.

Falls die Aufzugskabine 1 im Aufzugsschacht 9 ausserhalb eines Stockwerkbereichs stehen bleibt, kann die Kabinentür lediglich eine Spaltbreite geöffnet werden, weil der verlängerte erste Lastarm 11 schon zu Beginn des Öffnungsvorganges geschwenkt wird und dabei an der Schachtwand 8 bzw. der Stockwerktür ansteht. In dieser Stellung wird der weitere Öffnungsvorgang der Kabinentür durch die Stopeinrichtung 5 mechanisch blockiert.If the elevator car 1 in the elevator shaft 9 remains outside a floor area, the car door can only be opened a gap width because the elongated first load arm 11 is pivoted at the beginning of the opening process and is in contact with the shaft wall 8 or the floor door. In this position, the further opening process of the cabin door is mechanically blocked by the stop device 5.
