In den Fig. 1 bis 10 ist mit 1 eine Aufzugskabine bezeichnet, die auf einem Stockwerk 2 steht. Die Aufzugskabine 1 wird in einem durch Schachtwände 3 gebildeten Aufzugsschacht 4 verfahren. In den Figuren steht die Aufzugskabine 1 auf dem Stockwerk 2. Beim Stockwerkhalt wird die Position der Aufzugskabine 1 soweit ausgeregelt, bis eine Kabinenschwelle 5 bündig mit einer Stockwerkschwelle 6 steht. Entlang der Kabinenschwelle 5 wird eine Kabinentür 7 und entlang der Stockwerkschwelle 6 eine Stockwerktür 8 verfahren. Die Kabinentür 7 wird von einem nicht dargestellten Türantrieb geöffnet und geschlossen, dabei wird die Stockwerktür 8 von an der Kabinentür 7 angeordneten nicht dargestellten Mitnehmern geöffnet und geschlossen.1 to 10, 1 is an elevator car referred to, which stands on a floor 2. The Elevator car 1 is in a through shaft walls 3rd Move elevator shaft 4 formed. In the figures it says the elevator car 1 on the floor 2. At the floor stop the position of the elevator car 1 is adjusted so far until a cabin threshold 5 is flush with one Floor threshold 6 stands. Along cabin threshold 5 becomes a car door 7 and along the floor threshold 6 move a floor door 8. The cabin door 7 is from a door drive, not shown, opened and closed, thereby the floor door 8 of the Cabin door 7 arranged not shown drivers opened and closed.

Ein sich über die Länge der Kabinenschwelle 5 und Kabinentürhöhe erstreckender Lichtvorhang 9 einer Lichtschranke bestehend aus erster Senderleiste 10 und Empfängerleiste 11 blockiert die Aufzugskabine 1 falls Personen oder Gegenstände im Bereich der Kabinentüren 7 oder Stockwerktüren 8 sind. Die sich über die Kabinentürhöhe erstreckende am einen Ende der Kabinenschwelle 5 angeordnete erste Senderleiste 10 mit beispielsweise im Infrarotbereich arbeitenden Lichtquellen erzeugt beispielsweise 16 horizontale Lichtstrahlen, die von der am anderen Ende der Kabinenschwelle 7 angeordneten Empfängerleiste 11 mit Lichtempfängern detektiert werden. One over the length of the sleeper 5 and Cabin door height extending light curtain 9 one Light barrier consisting of first transmitter strip 10 and Receiver bar 11 blocks the elevator car 1 if People or objects in the area of the cabin doors 7 or floor doors 8. Which is about the Cabin door height extending at one end of the Cabin sill 5 arranged with first transmitter strip 10 for example, light sources working in the infrared range generates, for example, 16 horizontal beams of light from that arranged at the other end of the sleeper 7 Receiver bar 11 can be detected with light receivers.

Je ein Lichtempfänger liegt je einem Lichtsender gegenüber, sodass der Lichtstrahl des einen Lichtsenders auf den einen Lichtempfänger auftrifft, in dem beispielsweise eine Photodiode den Lichtstrahl in ein elektrisches Signal umwandelt. Falls mindestens ein Lichtstrahl von Personen oder Gegenständen unterbrochen wird, bleibt die Aufzugskabine 1 blockiert.A light receiver is opposite a light transmitter, so that the light beam from one light transmitter onto the one Light receiver strikes, in which, for example, a Photodiode the light beam into an electrical signal converts. If at least one beam of light from people or objects is interrupted, the remains Elevator car 1 blocked.

Am empfängerleistenseitigen Ende der Stockwerkschwelle 6 ragt eine Abdeckplatte 12 in den Lichtvorhang 9 und ist so bemessen, dass ein Lichtstrahl anstatt auf die Empfängerleiste 11 auf die Abdeckplatte 12 trifft. Im vorliegenden Ausführungsbeispiel ist die Abdeckplatte 12 an einem schwenkbaren Bolzen 13 angeordnet. Bei geschlossenen Kabinentüren 7 und Stockwerktüren 8 ragt die Abdeckplatte 12 in den Lichtvorhang 9 und deckt einen Lichtstrahl ab. Beim Öffnungsvorgang der Türen 7, 8 trifft die eine Stockwerktür 8 auf eine am Bolzen 13 angeordnete Fahne 14 und schwenkt die Abdeckplatte 12 aus dem Lichtvorhang 9. Beim Schliessvorgang der Türen 7, 8 dreht der Bolzen 13 unter der Krafteinwirkung einer Feder 15 in die Ausgangslage zurück, sodass die Abdeckplatte 12 wieder in den Lichtvorhang 9 der auf dem Stockwerk 2 stehenden Aufzugskabine 1 ragt.At the end of floor threshold 6 on the receiver bar side a cover plate 12 projects into the light curtain 9 and is so dimensioned that a light beam instead of on the Receiver bar 11 meets the cover plate 12. in the In the present exemplary embodiment, the cover plate 12 is on a pivotable bolt 13 is arranged. When closed Cabin doors 7 and floor doors 8 protrude from the cover plate 12 in the light curtain 9 and covers a light beam. When the doors 7, 8 open, one hits Floor door 8 on a flag 14 arranged on the bolt 13 and pivots the cover plate 12 out of the light curtain 9. When the doors 7, 8 are closed, the bolt 13 rotates under the force of a spring 15 in the Starting position back, so that the cover plate 12 in the light curtain 9 standing on the floor 2 Elevator car 1 protrudes.

Der Vorteil einer schwenkbaren Abdeckplatte 12 liegt in der unbeeinträchtigten Funktion der Lichtschranke als Sicherheitselement bei offener Kabinentür 7 und als Positionselement bei geschlossener Tür. Anstelle der Feder 15 kann auch ein Antrieb die Schwenkbewegung des Bolzens 13 übernehmen.The advantage of a pivotable cover plate 12 is that undisturbed function of the light barrier as Security element with open cabin door 7 and as Position element with the door closed. Instead of the spring 15, a drive can also pivot the pin 13 take.

In einer weiteren Ausführungsvariante ist eine feste Abdeckplatte 12 vorgesehen. In diesem Fall ist ein Lichtstrahl bei offenen Türen 7, 8 unterbrochen. Die Steuerung muss dann unterscheiden können, ob es sich um einen Gegenstand oder um die Abdeckplatte 12 selbst handelt, der oder die den Lichtstrahl unterbricht. In a further embodiment variant, there is a fixed one Cover plate 12 is provided. In this case it is a Light beam interrupted with doors 7, 8 open. The The control must then be able to differentiate whether it is an object or around the cover plate 12 itself acts that interrupts the light beam.

Eine Aufzugssteuerung 19 steht in Verbindung und tauscht Daten und Steuerbefehle aus mit einer Kabinensteuerung 20 und einer Motorsteuerung 21. Die Lichtstrahlen des Lichtvorhanges 9 treffen auf die Lichtempfänger, beispielsweise Photodioden D1 ... D16 der Empfängerleiste 11 auf. Die auftreffenden Lichtstrahlen werden von den Photodioden D1 ... D16 in elektrische Signale umgewandelt, die von der Kabinensteuerung 20 ausgewertet werden. Falls eine oder mehrere Photodioden D1 ... D16 kein entsprechendes Signal abgeben, leitet die Kabinensteuerung 20 ein Signal an die Aufzugssteuerung 19 weiter, die die Aufzugskabine 1 solange blockiert, bis sämtliche Fahrbedingungen einschliesslich intakter Lichtvorhang 9 erfüllt sind.Fig. 6 shows an elevator system with several floors 2.1, 2.2, 2.3, several cover plates 12.1, 12.2, 12.3, several floor sleepers 6.1, 6.2, 6.3, a motor 16, which drives a traction sheave 17, by means of which the Elevator car 1 and a counterweight 18 in elevator shaft 4 is proceeded. An elevator control 19 is shown in FIG Connection and exchanges data and control commands with a cabin controller 20 and an engine controller 21. Die Light rays from the light curtain 9 hit the Light receivers, for example photodiodes D1 ... D16 Receiver bar 11 on. The striking rays of light are converted into electrical by the photodiodes D1 ... D16 Converted signals from the cabin controller 20 be evaluated. If one or more photodiodes D1 ... D16 does not emit a corresponding signal, directs the Car control 20 sends a signal to elevator control 19 continue, which blocks the elevator car 1 until all driving conditions including intact Light curtain 9 are met.

Zur Bestimmung der genauen Lage der Aufzugskabine 1 im Aufzugsschacht 4, auch Kabinenposition genannt, führt die Aufzugskabine 1 eine Lernfahrt durch, bei der jedes Stockwerk 12.1, 12.2, 12.3 angefahren wird. Im gezeigten Beispiel der Fig. 6 ist die angefahrene Position auf dem Stockwerk 2.2 der Aufzugskabine 1 derart, dass die Abdeckplatte 12.2 beispielsweise die zweite Photodiode D2 abdeckt. Diese Grobposition wird von der Aufzugssteuerung 19 gespeichert. Die genaue Position wird in einer zweiten Fahrt manuell angefahren und als Sollwert SD8, beispielsweise die Position der achten Diode D8 abgespeichert. Die Aufzugskabine 1 erhält nun ihren Fahrbefehl, beispielsweise zweites Stockwerk 2.2. Dabei fährt die Aufzugskabine 1 die in der Lernfahrt ermittelte Grobposition der Photodiode D2 an und landet beispielsweise auf der Position der Photodiode D3, was aufgrund des durch die Abdeckplatte 12.2 unterbrochenen Lichtstrahles von der Kabinensteuerung 20 detektiert wird und als Istwert an die Aufzugssteuerung 19 weitergeleitet wird. Aus Sollwert und Istwert entsteht eine Korrekturgrösse, mit der die Aufzugskabine 1 solange bewegt wird, bis die Aufzugskabine 1 die Sollposition SD8 der manuellen Lernfahrt erreicht hat.To determine the exact position of the elevator car 1 in Elevator shaft 4, also called cabin position, leads the Elevator car 1 through a learning trip, in which each Floor 12.1, 12.2, 12.3 is approached. In the shown Example of Fig. 6 is the approached position on the Floor 2.2 of the elevator car 1 such that the Cover plate 12.2, for example, the second photodiode D2 covers. This rough position is from the elevator control 19 saved. The exact position is in a second Travel started manually and as setpoint SD8, for example the position of the eighth diode D8 saved. The elevator car 1 now receives its Travel command, for example second floor 2.2. there the elevator car 1 drives the one determined in the learning drive Coarse position of the photodiode D2 and lands, for example on the position of the photodiode D3, which is due to the cover plate 12.2 interrupted light beam from the Cabin control 20 is detected and the actual value to the Elevator control 19 is forwarded. From setpoint and The actual value creates a correction variable with which the Elevator car 1 is moved until the elevator car 1 reaches the target position SD8 of the manual learning run Has.
