Abstract

A locking system for the doors of a lift comprises a solenoid (1) with armature (2) and air bellows (3). The latter communicates via a tube (4) with the bellows (26) for the lock. This has a reinforced front surface (22) and an internal spring (14) to bias it into the extended position. It is withdrawn by vacuum from the first bellows when the armature is moved. On the surface of the second bellows is a roller (6) operating the door for the lift shaft by means of a thrust rod (8). The movement of the two bellows is determined by microswitches feeding a monitoring system connected to an auxiliary vacuum pump.

Das erfindungsgemässe Mitnehmer- und Entriegelungssystem funktioniert wie folgt:
Als Uebertragungsmedium ist vorzugsweise ein Gas, zum Beispiel Luft vorgesehen. Die Luft befindet sich in einem geschlossenen System, gebildet aus den Volumina des mit dem Elektromagneten 1 verbundenen Luftbalges 3, des Luftschlauches 4 und der Mitnehmer- und Entriegelungskurve 5. Im spannungslosen Zustand des Elektromagneten 1 drückt die Feder 14 die Mitnehmer- und Entriegelungskurve 5 nach vorn und saugt die Luft aus dem Luftbalg 3, worauf dieser zusammengezogen wird und den Magnetanker 2 aus der Riegelöffnung 11.1 der Kabinentür 11 herauszieht und die Kabinentür 11 entriegelt. Die ausgefahrene oder abgefallene Mitnehmer- und Entriegelungskurve 5 fährt beim Einfahren der Kabine in das Zielstockwerk zwischen die Mitnehmer- und Entriegelungsrollen 6 und spreizt diese beim Auflaufen über die angeschrägten Kurveneintrittsflanken 22 in den in der Fig. 2 gezeigten Zustand. Beim Spreizen der Mitnehmer- und Entriegelungsrollen 6 heben diese über die Zuglaschen 15 die Schubstange 8 nach oben und entriegeln durch herausheben des Riegels 10 aus dem Riegelschlitz 24 in einem Schachttürrahmenteil 24 die Schachttür 20. In diesem Zustand des Mitnehmer- und Entriegelungssystems sind also die Kabinentür 11 und die Schachttür 20 entriegelt und zwecks gemeinsamer Mitnahme beim nachfolgenden Oeffnen mechanisch gekuppelt.The driver and unlocking system according to the invention works as follows:

The air is in a closed system, formed from the volumes of the air bellows 3 connected to the electromagnet 1, the air hose 4 and the driver and unlocking curve 5. When the electromagnet 1 is de-energized, the spring 14 presses the driver and unlocking curve 5 in front and sucks the air out of the air bellows 3, whereupon the latter is drawn together and pulls the magnet armature 2 out of the bolt opening 11.1 of the cabin door 11 and unlocks the cabin door 11. The extended or dropped driver and unlocking curve 5 travels between the driver and unlocking rollers 6 when the cabin moves into the destination floor and spreads them over the beveled curve entry flanks 22 in the state shown in FIG. 2 when it approaches. When the driving and unlocking rollers 6 are spread, they lift the push rod 8 upward via the pull tabs 15 and unlock the shaft door 20 by lifting the bolt 10 out of the locking slot 24 in a shaft door frame part 24. In this state of the driving and unlocking system, the cabin door is 11 and the shaft door 20 are unlocked and mechanically coupled for the purpose of taking them along when they are subsequently opened.

Vor dem Wegfahren des Aufzuges von einer Haltestelle werden die Schacht- und Kabinentür 20, 11 vom nicht dargestellten Türantrieb geschlossen und in der Geschlossenstellung verriegelt. Das Verriegeln erfolgt durch Einschalten der Speisespannung zum Elektromagneten 1, worauf der Luftbalg 3 auseinandergezogen und die Mitnehmer- und Entriegelungskurve 5 zusammengezogen wird. Das Zusammenziehen der Mitnehmer- und Entriegelungskurve 5 lässt die Mitnehmer- und Entriegelungsrollen 6 zusammenklappen (Fig.4), die Schubstange 8 nach unten ziehen und den Riegel 10 in den Riegelschlitz 24 einfahren, worauf die Schachttür verriegelt ist. Auf der Betätigungsseite wird der magnetisierbare Teil des Magnetankers 2.2 in den Elektromagnet 1 durch Magnetkraft hineingezogen, der vordere nicht magnetisierbare Teil 2.1 des Magnetankers 2 in die Riegelöffnung 11.1 der Kabinentür 11 eingefahren und die Kabinentür 11 verriegelt.Before leaving the elevator, be off a stop the shaft and cabin door 20, 11 from not shown Door operator closed and in the closed position locked. Locking takes place by switching on the Supply voltage to the electromagnet 1, whereupon the air bellows 3 pulled apart and the driver and unlocking curve 5 is contracted. Contraction of the driver and Unlocking curve 5 leaves the driver and Fold the unlocking rollers 6 (Fig. 4), the push rod 8 pull down and latch 10 into latch slot 24 drive in, whereupon the shaft door is locked. On the Actuation side is the magnetizable part of the Magnet armature 2.2 in the electromagnet 1 by magnetic force drawn in, the front non-magnetizable part 2.1 of the Magnet armature 2 in the bolt opening 11.1 of the cabin door 11 retracted and the cabin door 11 locked.

Es ist lediglich darauf zu achten, dass der Magnetanker 2 die Kabinentür 11 verriegeln kann. Der Luftschlauch 4 kann wie ein flexibles Elektrokabel verlegt und teilweise frei hängend zwischen Kabine 12 und Kabinentür 11 installiert werden.In the driver and unlocking system according to the invention only the driver and unlocking curve 5 at one to attach a specific place to the cabin door 11; of the Actuator with electromagnet 1 and air bellows 3 can any structurally suitable location of the cabin 12 be attached. It is only important to ensure that the Magnetic armature 2 can lock the cabin door 11. Of the Air hose 4 can be laid and laid like a flexible electrical cable partially hanging freely between cabin 12 and cabin door 11 be installed.

In der gezeigten Version sind die Kabinentür 11 und die Schachttür 20 im spannungslosen Zustand des Elektromagneten 1 entriegelt. Die Entriegelungsfunktion lässt sich umkehren, wenn die Druckfeder 14 im Luftbalg 3 eingesetzt würde und der Magnetanker 2 im Teil 2.1 magnetisierbar wäre. Dann erfolgt eine Entriegelung nur, wenn Spannung an den Elektromagneten 1 angelegt wird.In the version shown, the cabin door 11 and the Landing door 20 in the de-energized state of the electromagnet 1 unlocked. The unlocking function can be reversed if the compression spring 14 would be used in the air bellows 3 and Magnetic armature 2 in part 2.1 would be magnetizable. Then done unlocking only when voltage is applied to the electromagnet 1 is created.

Der elastische Lagerblock 7 kann auch durch eine konventionelle Konstruktion mit mechanischen Rollenhebellagern und einer Zugfeder zwischen den Rollenhebeln ausgeführt werden.The elastic bearing block 7 can also by a conventional construction with mechanical roller lever bearings and a tension spring between the roller levers become.

Die vorhergehend erwähnten Versteifungen der Kurveneintrittsflanken 22, der Kurvenflanken 21 und der Frontfläche 25 der Mitnehmer- und Entriegelungskurve 5 kann mittels Metalleinlagen im Material der Mitnehmer- und Entriegelungskurve 5 erreicht werden. Das Material für die Herstellung der Mitnehmer- und Entriegelungskurve 5 allgemein und des Luftbalgteils 26 im speziellen besteht vorzugsweise aus einem flexiblen, aber nicht dehnbaren Kunststoff. Der Luftbalg 3 der Betätigungseinrichtung besteht vorzugsweise ebenfalls aus flexiblem, aber nicht dehnbarem Kunststoff, wobei die hintere und vordere Stirnplatte 3.1 und 3.2 je aus hartem und stabilem Material bestehen. Die parallele Führung des Luftbalges ist durch den mit der hinteren Stirnplatte 3.1 verbundenen und im Elektromagnet 1 geführten Ankerbolzen 2 gewährleistet. Als Bewegungskontrolle der Luftbälge 3 und 26 werden in einer weiter entwickelten Form der Erfindung Mikroschalter eingesetzt, welche im Innern der Luftbälge 3, 26 an einer Stirnwand plaziert, und im zusammengezogenen Zustand eines Luftbalges 3 oder 26 betätigt werden. Gasdicht herausgeführte Anschlussdrähte werden vorzugsweise zu einer Ueberwachungsschaltung geführt. Die Ueberwachungsschaltung kann eine mit dem geschlossenen Gassystem permanent verbundene Vakuumpumpe steuern, welche bei unzulässigem Nachlassen des Unterdruckes den funktionsbedingt erforderlichen Unterdruck wieder herstellt.The previously mentioned stiffeners of the Curve entry flanks 22, the curve flanks 21 and the Front surface 25 of the driver and unlocking curve 5 can by means of metal inserts in the material of the driver and Unlocking curve 5 can be reached. The material for the Production of the driver and unlocking curve 5 in general and the bellows part 26 in particular is preferably made of a flexible but not stretchable plastic.
