Abstract

Using this device, noise and vibration which occur during actuation and unlatching of a shaft door (1) which is moved by a driven car door (2) can be largely prevented. To this end, a first coupling element (3) which is mounted on the shaft door (1) and a second coupling element (4) which is mounted on the car door (2) are constructed as magnets and are arranged in such a manner that a north pole (N) of the first coupling element (3) is opposite a north pole (N) of the second coupling element (4), and a south pole (S) of the first coupling element (3) is opposite a south pole (5) of the second coupling element (4), separated by an air gap in the movement direction of the doors. Provided on a latching element of the shaft door (1) is a further magnet whose one pole is located opposite a similar pole of the second coupling element (4), with an air gap, in the movement direction of the doors. When a car stops at a floor, the repulsion forces of the magnets initially unlatch the shaft door (1) without being touched, and then move without being touched when the car door (2) opens. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Betätigen und Entriegeln der Schachttüren eines Aufzuges, die ein an der Schachttür angeordnetes erstes Kupplungsglied und ein an der Kabinentür angeordnetes zweites Kupplungsglied aufweist, das im Bereich eines Stockwerkes mit dem ersten Kupplungsglied in Eingriff gebracht werden kann, wobei ein an der Schachttür angeordnetes Verriegelungsglied vorgesehen ist, welches beim Halt der Kabine auf einem Stockwerk mit dem zweiten Kupplungsglied derart in Wirkverbindung steht, dass die Schachttür entriegelt wird und geöffnet werden kann.The invention relates to a device for actuating and unlocking the shaft doors of an elevator, which has a first coupling element arranged on the shaft door and a second coupling element arranged on the car door, which can be brought into engagement with the first coupling element in the area of one floor, one at the shaft door arranged locking member is provided, which is operatively connected to the second coupling member when the cabin is held on one floor such that the shaft door is unlocked and can be opened.

Derartige Vorrichtungen haben den Zweck, horizontal verschiebbare Kabinen- und Schachttüren mittels eines auf der Kabine angebrachten Türantriebes bei einem Halt auf einem Stockwerk synchron laufend zu öffnen bzw. zu schliessen.Such devices have the purpose of opening and closing horizontally displaceable cabin and shaft doors synchronously by means of a door drive mounted on the cabin when stopped on a floor.

Mit der englischen Patentschrift 587984 ist eine Vorrichtung zum gleichzeitigen Betätigen der Kabinen- und Schachttüren einer Aufzugsanlage bekannt geworden, bei der ein auf der Kabine angeordneter Elektromagnet über ein Hebelgestänge ein an der Kabinentür beweglich angebrachtes Kupplungsglied betätigt. Das Kupplungsglied weist einen keilförmigen Querschnitt auf und wird bei erregtem Elektromagnet in entkuppelter Stellung gehalten. Ein an der Schachttür angebrachtes festes Kupplungsglied weist eine V-förmige Nut auf, welche dem keilförmigen Querschnitt des beweglichen Kupplungsgliedes angepasst ist. Bei einem Stockwerkhalt fällt der Elektromagnet ab, wobei die beiden Kupplungsglieder mittels Federkraft zum Eingriff kommen. Hierbei drückt das bewegliche Kupplungsglied auf eine an einem Hebel gelagerte Rolle, so dass eine am anderen Hebelende befestigte Stange nach oben verschoben wird, Das obere Ende der Stange ist mit einer Klinke verbunden, die dadurch nach oben geschwenkt wird, wobei die Schachttür entriegelt und ein Steuerstromkreis geöffnet wird.With the English patent specification 587984 a device for the simultaneous actuation of the car and shaft doors of an elevator system has become known, in which an electromagnet arranged on the car actuates a coupling member movably attached to the car door via a lever linkage. The coupling member has a wedge-shaped cross section and is held in the uncoupled position when the electromagnet is excited. A fixed coupling member attached to the shaft door has a V-shaped groove which is adapted to the wedge-shaped cross section of the movable coupling member. When the floor stops, the electromagnet falls off, the two coupling members engaging by means of spring force. Here, the movable coupling member presses on a roller mounted on a lever, so that a rod attached to the other end of the lever is shifted upward. The upper end of the rod is connected to a pawl that thereby being pivoted upwards, the shaft door being unlocked and a control circuit being opened.

Bei einer anderen bekannten Vorrichtung nach der US-Patentschrift 1876438, ist ein Elektromagnet unmittelbar über einem beweglichen Kupplungsglied in der Kabinentür eingebaut und mit dem Kupplungsglied durch ein Gelenk verbunden. Das bewegliche Kupplungsglied wird aufgrund der Schwerkraft in entkuppelter Stellung gehalten, während es bei erregtem Elektromagnet mit einem an der Schachttür angebrachten festen Kupplungsglied zum Eingriff kommt. Ein weiterer an der Kabine angeordneter Elektromagnet ist mit einer Hebelanordnung verbunden, an welcher ein Nocken gelenkig befestigt ist. Der Nocken liegt an einer an einem Hebel gelagerten Rolle an, wobei der Hebel mit einer Klinke verbunden und drehbar an der Schachttür angeordnet ist. Bei Beginn der Tür-Öffnungsbewegung fällt der weitere Elektromagnet ab, so dass der Nocken nach unten bewegt und gegen die Rolle gedrückt wird. Hierbei führt der Hebel und damit auch die Klinke eine Schwenkbewegung aus, so dass die Schachttür entriegelt und ein Steuerstromkreis geöffnet wird.In another known device according to US Pat. No. 1876438, an electromagnet is installed directly above a movable coupling member in the cabin door and is connected to the coupling member by a joint. The movable coupling member is held in the uncoupled position due to the force of gravity, while when the electromagnet is excited, a fixed coupling member attached to the shaft door engages. Another electromagnet arranged on the cabin is connected to a lever arrangement to which a cam is articulated. The cam rests on a roller mounted on a lever, the lever being connected to a pawl and being rotatably arranged on the shaft door. At the start of the door opening movement, the further electromagnet drops off, so that the cam is moved down and pressed against the roller. Here, the lever and thus also the pawl perform a swiveling movement, so that the shaft door is unlocked and a control circuit is opened.

Bei vorstehend beschriebenen Vorrichtungen entstehen beim Ein- und Auskuppeln der Kupplungsglieder sowie beim Ein- und Ausschalten der Elektromagnete Geräusche und Vibrationen, die von den Fahrgästen als unangenehm empfunden werden können. Um bei derartigen Vorrichtungen einwandfreies Einkuppeln zu gewährleisten, müssen die beiden Kupplungsglieder möglichst genau gegenüber liegen, so dass hohe Anforderungen an die Fertigungs- bzw. Montagegenauigkeit gestellt werden müssen.In the devices described above, noises and vibrations occur when the coupling members are engaged and disengaged, and when the electromagnets are turned on and off, which passengers may find unpleasant. In order to ensure proper engagement with such devices, the two coupling members must lie opposite each other as precisely as possible, so that high demands must be placed on the manufacturing and assembly accuracy.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung gemäss Oberbegriff zu schaffen, bei welcher Geräusche und Vibrationen beim Ein- bzw. Auskuppeln der Kupplungsglieder und Ent- bzw. Verriegeln der Schachttüren vermieden werden, keine hohen Anforderungen an Fertigungs- und Montagegenauigkeiten gestellt werden müssen und weniger mechanische Bauteile benötigt werden.The invention has for its object to provide a device according to the preamble, in which noises and vibrations when engaging or disengaging the coupling members and unlocking or locking the shaft doors are avoided, no high demands on manufacturing and assembly accuracy have to be provided and fewer mechanical components are required.

Diese Aufgabe wird durch die im Patentanspruch 1 gekennzeichnete Erfindung gelöst. Hierbei bestehen die Kupplungsglieder aus Magnete die derart ausgebildet sind, dass im Bereich eines Stockwerkes ein Nordpol des ersten Kupplungsgliedes einem Nordpol des zweiten Kupplungsgliedes, und ein Südpol des ersten Kupplungsgliedes einem Südpol des zweiten Kupplungsgliedes je durch einen Luftspalt getrennt in Bewegungsrichtung der Türen gegenüberliegen. Am Verriegelungsglied ist ein weiterer Magnet angeordnet, der im Bereich eines Stockwerkes in Bewegungsrichtung der Türen mit einem Pol einem gleichnamigen Pol des zweiten Kupplungsgliedes mit Luftspalt gegenüberliegt.This object is achieved by the invention characterized in claim 1. Here, the coupling members consist of magnets which are designed such that a north pole of the first coupling member faces a north pole of the second coupling member, and a south pole of the first coupling member opposite a south pole of the second coupling member, separated by an air gap in the direction of movement of the doors. A further magnet is arranged on the locking member, which is located in the area of one floor in the direction of movement of the doors with one pole opposite a pole of the same name of the second coupling member with an air gap.

Die mit der Erfindung erzielten Vorteile sind insbesondere darin zu sehen, dass wegen des berührungslosen Ineinandergreifens der Kupplungsglieder und des berührungslosen Mitnehmens der Schachttür sowie der berührungslosen Betätigung des Verriegelungsgliedes Geräusche und Vibrationen weitgehend vermieden werden. Hierbei wird jeweils kurz vor dem Ende der Türbewegung die Schachttür durch die abstossenden Kräfte der gleichnamigen Pole allmählich bis zum Stopp verlangsamt. Die Türen können schneller geöffnet und dadurch die effektive Tür-Offenhaltezeit vergrössert werden, da die bei manchen konventionellen Vorrichtungen für Kupplung und Entriegelung erforderliche kleine Anfangsgeschwindigkeit nicht notwendig ist. Weitere Vorteile sind darin zu sehen, dass weniger mechanische Bauteile benötigt werden und, wegen der Luftspalte zwischen den Magnetpolen, gröbere Fertigungs- bzw. Montagetoleranzen zulässig sind. Bei einem Halt auf einem Stockwerk und einem Spannungsausfall können die Türen von Hand geöffnet werden, da dann zwischen den Kupplungsgliedern und zwischen dem zweiten Kupplungsglied und dem Verriegelungsglied mechanischer Kontakt hergestellt werden kann.The advantages achieved by the invention are to be seen in particular in the fact that noises and vibrations are largely avoided because of the contactless interlocking of the coupling members and the contactless driving of the shaft door as well as the contactless actuation of the locking member. Here, shortly before the end of the door movement, the shaft door is gradually slowed down to a stop by the repelling forces of the poles of the same name. The doors can be opened faster, thereby increasing the effective door hold-open time, since the low initial speed required for some conventional devices for coupling and unlocking is not necessary. Further advantages can be seen in the fact that fewer mechanical components are required and, because of the air gaps between the magnetic poles, coarser manufacturing and assembly tolerances are permissible. If the vehicle stops on a floor and there is a power failure, the doors can be opened by hand, since mechanical contact can then be made between the coupling members and between the second coupling member and the locking member.

In den Fig. 1 und 2 sind mit 1 eine Schachttür und mit 2 eine Kabinentür eines Aufzuges bezeichnet. Ein erstes Kupplungsglied 3 ist an der Schachttür und ein zweites Kupplungsglied 4 an der Kabinentür 2 angeordnet. Die Kupplungsglieder 3, 4 sind Magnete gleicher Polstärke, wobei in einer bevorzugten Ausführungsform das erste Kupplungsglied 3 ein u-förmiger Permanentmagnet ist und das zweite Kupplungsglied 4 aus zwei gleichen Elektromagneten 4.1, 4.2 besteht. Die Kupplungsglieder 3, 4 sind derart angeordnet, dass die Elektromagnete 4.1, 4.2 im Bereich eines Stockwerkes Magnetpole bildende Schenkel 3.1, 3.2 des u-förmigen Permanentmagneten an ihren Aussenseiten mit Luftspalt überlappen. Hierbei liegt der eine Elektromagnet 4.1 mit seinem Nordpol N dem Nordpol N, und der andere Elektromagnet 4.2 mit seinem Südpol S dem Südpol S des u-förmigen Permanentmagneten in Bewegungsrichtung der Türen gegenüber. In einer weiteren Ausführungsform kann anstelle des u-förmigen Permanentmagneten ein u-förmiger Elektromagnet verwendet werden, wobei der eine Schenkel 3.1 einen Nordpol und der andere Schenkel 3.2 einen Südpol bildet.
Gemäss Fig. 3 bestehen die Elektromagneten 4.1, 4.2 im Prinzip wie bekannt aus Hohlspulen mit Kernen aus ferromagnetischem Material, wobei wie ebenfalls bekannt, die Elektromagnete durch Vertauschen der Anschlüsse einer speisenden Gleichspannungsquelle 5 umgepolt werden können.1 and 2, 1 denotes a shaft door and 2 denotes a car door of an elevator. A first coupling member 3 is arranged on the shaft door and a second coupling member 4 on the cabin door 2. The coupling members 3, 4 are magnets of the same pole strength, wherein in a preferred embodiment the first coupling member 3 is a U-shaped permanent magnet and the second coupling member 4 consists of two identical electromagnets 4.1, 4.2. The coupling members 3, 4 are arranged such that the legs 3.1, 3.2 of the U-shaped permanent magnet, which form magnetic poles in the area of one floor, overlap with an air gap on their outer sides. Here, the one electromagnet 4.1 with its north pole N faces the north pole N, and the other electromagnet 4.2 with its south pole S faces the south pole S of the u-shaped permanent magnet in the direction of movement of the doors. In a further embodiment, a u-shaped electromagnet can be used instead of the u-shaped permanent magnet, one leg 3.1 forming a north pole and the other leg 3.2 forming a south pole.
According to FIG. 3, the electromagnets 4.1, 4.2 in principle consist, as is known, of hollow coils with cores made of ferromagnetic material, the electromagnets also being known, as is also known Reversing the connections of a supplying DC voltage source 5 can be reversed.

Gemäss Fig. 4 weist das Verriegelungsglied 6 eine an der Schachttür 1 drehbar gelagerte Klinke 7 und einen Kniehebel 8 auf. Der Kniehebel 8 besteht aus einem ersten und zweiten Hebel 9, 10, die an einem Ende gelenkig miteinander verbunden sind. Das andere Ende des ersten Hebels 9 ist drehbar an der Klinke 7 angebracht, während das andere Ende des zweiten Hebels 10 drehbar an der Schachttür 1 gelagert ist. Am Kniehbebel 8 ist im Bereich des gemeinsamen Drehpunktes 11 der beiden Hebel 9, 10 ein stabförmiger Permanentmagnet 12 befestigt, dessen einer Pol bei Anwesenheit der Kabine auf einem Stockwerk einem gleichnamigen Pol des zweiten Kupplungsgliedes 4 in Bewegungsrichtung der Türen mit Luftspalt gegenüberliegt. Bei geschlossener Schachttür 1 ist die Klinke 7 auf nicht weiter dargestellte Weise mit einem Schachttürrahmen verklinkt.4, the locking member 6 has a pawl 7 rotatably mounted on the shaft door 1 and a toggle lever 8. The toggle lever 8 consists of a first and second lever 9, 10, which are articulated at one end. The other end of the first lever 9 is rotatably attached to the pawl 7, while the other end of the second lever 10 is rotatably mounted on the shaft door 1. In the area of the common pivot point 11 of the two levers 9, 10, a rod-shaped permanent magnet 12 is attached to the knee lever 8, one pole of which, in the presence of the cabin on one floor, is opposite a pole of the same name of the second coupling member 4 in the direction of movement of the doors with an air gap. When the shaft door 1 is closed, the pawl 7 is latched to a shaft door frame in a manner not shown.

Die vorstehend beschriebene Vorrichtung arbeitet wie folgt:
Bei einem Halt auf einem Stockwerk wird zuerst das elektromagnetische zweite Kupplungsteil 4 aktiviert, wobei durch die abstossenden Kräfte der gleichnamigen Pole, beispielsweise zweier Nordpole, des stabförmigen Permanentmagneten 12 und des Elektromagneten 4.1 der Kniehebel 8 berührungslos in Pfeilrichtung durchgedrückt und die Klinke 7 nach oben geschwenkt wird, so dass die Schachttür 1 entriegelt wird (Fig. 4). Danach wird ein auf der Kabine angeordneter, nicht dargestellter Türantrieb gestartet und die Schachttür 1 durch die zwischen dem ersten und zweiten Kupplungsteil 3, 4 wirkenden abstossenden Kräfte von der Kabinentür 2 berührungslos mitgenommen. Hierbei werden sich bei der beispielsweise durch den Pfeil (Fig. 2) gekennzeichneten Bewegungsrichtung der Türen, während der Beschleunigung der Luftspalt zwischen dem Elektromagneten 4.1 und dem Schenkel 3.1 des Permanentmagneten verkleinern und die abstossenden Kräfte zwischen den Nordpolen N vergrössern. Nach der Beschleunigung tritt wegen der gleichen Polstärken ein Gleichgewichtszustand ein, wobei der u-förmige Permanentmagnet in der Mitte zwischen den Elektromagneten 4.1, 4.2 liegt. Bei der Verzögerung verkleinert sich der Luftspalt zwischen dem Elektromagneten 4.2 und dem Schenkel 3.2 des Permanentmagneten, wobei sich gleichzeitig die abstossenden Kräfte zwischen den Südpolen S vergrössern, so dass die Schachttür 1 allmählich bis zum Stopp verlangsamt wird. Beim Schliessen der Türen laufen die gleichen Vorgänge in umgekehrter Reihenfolge wie beim vorstehend beschriebenen Öffnen ab. Nach dem Türschliessen wird das elektromagnetische zweite Kupplungsteil 4 entaktiviert, wobei die Klinke 7 abfällt und die Schachttür 1 wieder verriegelt wird.The device described above works as follows:
When stopping on a floor, the electromagnetic second coupling part 4 is activated first, whereby the repulsive forces of the poles of the same name, for example two north poles, the rod-shaped permanent magnet 12 and the electromagnet 4.1 push the toggle lever 8 without contact in the direction of the arrow and the pawl 7 is pivoted upwards is so that the shaft door 1 is unlocked (Fig. 4). Thereafter, a door drive (not shown) arranged on the cabin is started and the shaft door 1 is carried along by the cabin door 2 without contact by the repulsive forces acting between the first and second coupling parts 3, 4. This will decrease in the direction of movement of the doors, for example indicated by the arrow (Fig. 2), during acceleration, the air gap between the electromagnet 4.1 and the leg 3.1 of the permanent magnet and increase the repulsive forces between the north poles N. After acceleration an equilibrium state occurs because of the same pole strengths, the U-shaped permanent magnet lying in the middle between the electromagnets 4.1, 4.2. During the deceleration, the air gap between the electromagnet 4.2 and the leg 3.2 of the permanent magnet decreases, the repulsive forces between the south poles S increasing at the same time, so that the shaft door 1 is gradually slowed down to a stop. When the doors are closed, the same processes take place in the reverse order of the opening described above. After closing the door, the electromagnetic second coupling part 4 is deactivated, the pawl 7 falls off and the shaft door 1 is locked again.
