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 It is withdrawn by vacuum from the first bellows when the armature is moved.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.

Der elastische Lagerblock 7 ist im Beispiel als homogener Gummiblock vorgesehen, in welchem die Rollenbolzen 9 eingegossen sind, und der die elastische Spreizbewegung der Rollenbolzen 9 ermöglicht. In der Fig. 1 und 2 ist das Mitnehmer- und Entriegelungssystem im stromlosen, nicht betätigten Zustand dargestellt.In FIG. 1, an electromagnet 1, consisting of a magnet coil 1.1 and a magnet housing 1.2, is fastened to a cabin wall 12 behind a cabin door leaf 11 with a bolt opening 11.1. About half the length of a bolt-shaped magnet armature 2 projects into the central opening of the electromagnet 1. The magnet armature 2 consists in the front part 2.1 of magnetically non-conductive material and in the rear part 2.2 of magnetically conductive material. The rear part 2.2 is part of a rear end plate 3.1 of an air bellows 3, the front end plate 3.2 of which is fastened to a carrier plate 13 connected to the cabin wall 12. The air bellows 3 is connected via an air hose 4 emerging from the front end plate 3.2 to the internal volume of a driver and unlocking element 5, also designed as an air bellows and attached to the cabin door leaf 11, hereinafter referred to as driver and unlocking curve. Inside the driver and unlocking curve 5 there is at least one compression spring 14 which presses the driver and unlocking curve 5 into the extended position. On the side facing a shaft door 20, the entraining and unlocking curve 5 has a beveled curve entry flank 22 on both sides at the top and bottom, and on both sides a vertically running curve flank 21 each made of stiffened material. The front end forms a front surface 25 that runs parallel to the shaft door 20, is flat in the door bridging area and is chamfered at both ends. The actual bellows part of the driver and unlocking curve 5 is designated by 26 and is located between the front or front mentioned.

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:

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.
