Abstract

A sealing apparatus has inflatable hallow body portions extending around a car opening to close off the space between an elevator shaft wall and the car opening of an elevator car in a draftsproof and weatherproof manner when stopping at a floor. After the car stops at a floor, a pressurized fluid medium is utilized to inflate the hollow body until it is pressed against the shaft wall. The hollow body of the sealing apparatus is ventilated to atmosphere or to a vacuum before the departure of the elevator car from the floor such that the hollow body retracts so as to assure the spacing which is necessary for the free travel of the elevator car in the shaft. The sealing apparatus is monitored for low and excess pressure conditions.

In den Fig. 1 bis 8 ist mit 1 ein durch eine Schachtwand 2 und Schachtschiebetüren 3 abgegrenzter Aufzugsschacht bezeichnet. In ihm wird eine Aufzugskabine 4 mit Kabinenschiebetüren 5 geführt. Die Schachtöffnung wird im Randbereich einer Stockwerktür von einem Schachtabschluss 6 umfasst. Eine aus elastischem Material aufgebaute Dichtungsleiste 7 ist um die Kabinenöffnung angeordnet und überbrückt zeitweilig den Spalt zwischen Kabine und Randbereich der Stockwerktür. Die Dichtungsleiste 7 besteht aus einem oberen Teil 8, einem rechten Teil 9, einem unteren Teil 10 und einem linken Teil 11, die einen in den Fig. 4 und 5 dargestellten Querschnitt oder einen in den Fig. 6 und 7 dargestellten Querschnitt aufweisen. Mit 12 ist ein Stützkörper und mit 13 ein Hohlkörper der Dichtungsleiste 7 bezeichnet. Eine an der Kabine angeordnete Befestigungsleiste 14 umfasst den Stützkörper 12. Im Ausführungsbeispiel gemäss Fig. 4 und 5 dehnt sich der Hohlkörper 13 ballonartig aus, im Ausführungsbeispiel gemäss Fig. 6 und 7 dehnt sich der Hohlkörper 13 über Gelenke 15 scherenartig aus. Der zur Ausdehnung der Dichtungsleiste 7 nötige Druck wird von einer Druckquelle 16 erzeugt, die aus einem Kompressor und einer Hilfsdruckquelle, beispielsweise in Gestalt einer Pressluftflasche, besteht. Bei Ausfall des Kompressors wird der Druck automatisch von der Hilfsdruckquelle aufrecht erhalten. Das von der Druckquelle 16 verdichtete Druckmittel gelangt über ein Druckregelventil 17 in einen Druckspeicher 18, der seinerseits elektromagnetisch betätigte 3/2-Wegeventile 19 speist. An den ersten Auslassöffnungen der 3/2-Wegeventile 19 sind die Teile 8; 9; 10; 11 der Dichtungsleiste 7 angeschlossen. Die Druckmittelzuführung erfolgt über eine nicht dargestellte Öffnung im Stützkörper 12. Der Speisedruck wird von einem Druckschalter 20, der Druck in der Dichtungsleiste 7 von Druckschaltern 21 überwacht. Eine mit 22 bezeichnete Aufzugssteuerung übernimmt die Steuerung der elektromagnetisch betätigten 3/2-Wegeventile 19.1 to 8, 1 denotes an elevator shaft delimited by a shaft wall 2 and shaft sliding doors 3. An elevator car 4 with car sliding doors 5 is guided in it. The shaft opening is surrounded by a shaft closure 6 in the edge region of a storey door. A sealing strip 7 constructed of elastic material is arranged around the cabin opening and temporarily bridges the gap between the cabin and the edge area of the storey door. The sealing strip 7 consists of an upper part 8, a right part 9, a lower part 10 and a left part 11, which have a cross section shown in FIGS. 4 and 5 or a cross section shown in FIGS. 6 and 7. 12 with a support body and 13 with a hollow body of the sealing strip 7 is designated. A fastening strip 14 arranged on the cabin comprises the support body 12. In the exemplary embodiment according to FIGS. 4 and 5, the hollow body 13 expands in a balloon-like manner, in the exemplary embodiment according to FIGS. 6 and 7 the hollow body 13 extends over joints 15 in a scissor-like manner. The pressure required to expand the sealing strip 7 is generated by a pressure source 16, which consists of a compressor and an auxiliary pressure source, for example in the form of a compressed air bottle. If the compressor fails, the pressure is automatically maintained by the auxiliary pressure source. The pressure medium compressed by the pressure source 16 passes via a pressure control valve 17 into a pressure accumulator 18, which in turn feeds electromagnetically actuated 3/2-way valves 19. At the first outlet openings of the 3/2-way valves 19, the parts 8; 9; 10; 11 of the sealing strip 7 connected. The pressure medium is supplied via an opening (not shown) in the support body 12. The feed pressure is monitored by a pressure switch 20, the pressure in the sealing strip 7 by pressure switches 21. An elevator control designated 22 assumes control of the electromagnetically actuated 3/2-way valves 19.

Der in den Fig. 4 und 6 gezeigte Hohlkörper 13 ist in drucklosem Zustand derart bemessen, dass ein für die freie Fahrt der Aufzugskabine notwendiger Abstand vom Schachtabschluss 6 gewährleistet ist. Das bei Stockwerkhalt über eine nicht dargestellte Öffnung im Stützkörper 12 einströmende Druckmittel dehnt den elastischen aus in Richtung Schachtabschluss 6 hintereinanderliegenden Kammern bestehenden Hohlkörper 13 gemäss Fig. 5 ballonartig aus, so dass er gegen den Schachtabschluss 6 gepresst wird und dabei das Spiel zwischen der Aufzugskabine und dem Schachtabschluss 6 zugluft- und wetterfest abdichtet. Der in den Fig. 6 und 7 gezeigte elastische Hohlkörper 13 wird durch das einströmende Druckmittel in Richtung Schachtabschluss 6 scherenartig ausgedehnt. Dies deshalb, weil der faltenbalgartige Hohlkörper 13 an den Knickstellen Gelenke 15 in der Gestalt von Stellen mit verminderter Wandstärke aufweist. Vor der Wegfahrt der Aufzugskabine 4 von der Haltestelle wird der Hohlkörper 13 frei zur Atmosphäre entlüftet. Die dem Material des Hohlkörpers 13 anhaftende Elastizität bringt diesen dabei wieder in die Ausgangsform gemäss den Fig. 4 und 6 zurück.The hollow body 13 shown in FIGS. 4 and 6 is dimensioned in the unpressurized state such that one for the free Travel the elevator car necessary distance from the shaft end 6 is guaranteed. The pressure medium flowing into the support body 12 at a floor level via an opening (not shown) expands the elastic hollow body 13 consisting of chambers one behind the other in the direction of the shaft end 6 according to FIG. 5 so that it is pressed against the shaft end 6 and thereby the play between the elevator car and seals the shaft end 6 draft and weatherproof. The elastic hollow body 13 shown in FIGS. 6 and 7 is extended like scissors by the inflowing pressure medium in the direction of the shaft end 6. This is because the bellows-like hollow body 13 has joints 15 in the form of locations with reduced wall thickness at the kink locations. Before the elevator car 4 leaves the stop, the hollow body 13 is vented freely to the atmosphere. The elasticity adhering to the material of the hollow body 13 brings it back into the initial shape according to FIGS. 4 and 6.

Das Druckregelventil 17 der Fig. 8 liefert den für die Dichtungsleiste 7 gewünschten Speisedruck, vorausgesetzt, dass der von der Druckquelle 16 erzeugte Druck höher als der für die Dichtungsleiste 7 erforderliche Druck ist. Der Speisedruck wird von dem Druckschalter 20 überwacht, der bei Druckmangel oder Überdruck eine Druckmeldung an die Aufzugssteuerung 22 weiterleitet. Diese löst bei Druckmangel einen Alarm zweiter Priorität, bei Überdruck einen Alarm erster Priorität aus. Sobald die Aufzugskabine 4 auf der Haltestelle eingefahren ist, bringt die Aufzugssteuerung 22 die 3/2-Wegeventile 19 elektromagnetisch von einer zweiten, die Dichtungsleiste 7 frei gegen die Atmosphäre entlüftende Stellung in eine erste, die Dichtungsleiste 7 mit dem Speisedruck beaufschlagende Stellung. Die Ansteuerungsreihenfolge der 3/2-Wegeventile 19 wird abhängig von der Anordnung der Teile 8; 9; 10; 11 von der Aufzugssteuerung 22 bestimmt. Im Normalfall werden die vertikal angeordneten Teile 9; 11 als erste mit Druck beaufschlagt. Die Aufzugssteuerung 22 gibt die Wegfahrt der Aufzugskabine 4 von der Haltestelle erst dann frei, wenn alle Druckschalter 21 atmosphärischen Druck melden.The pressure control valve 17 of FIG. 8 supplies the feed pressure desired for the sealing strip 7, provided that the pressure generated by the pressure source 16 is higher than the pressure required for the sealing strip 7. The feed pressure is monitored by the pressure switch 20, which forwards a pressure message to the elevator control 22 in the event of a lack of pressure or excess pressure. This triggers a second priority alarm in the event of a lack of pressure and a first priority alarm in the event of overpressure. As soon as the elevator car 4 is retracted at the stop, the elevator control 22 electromagnetically brings the 3/2-way valves 19 from a second position, which vent the sealing strip 7 freely against the atmosphere, to a first position, which applies the supply pressure to the sealing strip 7. The control sequence of the 3/2-way valves 19 is dependent on the arrangement of the parts 8; 9; 10; 11 determined by the elevator control 22. In the normal case, the vertically arranged parts 9; 11 first with print acted upon. The elevator control 22 only enables the elevator car 4 to leave the stop when all pressure switches 21 report atmospheric pressure.

In einem weiteren Ausführungsbeispiel kann anstelle der Entlüftung zur Atmosphäre die Dichtungsleiste 7 zu einem Vakuum entlüftet werden. In diesem Fall ist die zweite Auslassöffnung der 3/2-Wegeventile 19 an die Saugleitung einer Vakuumquelle anzuschliessen. Die Entlüftung zu einem Vakuum bewirkt eine raschere Abfahrbereitschaft der Dichtungsleiste 7.In a further exemplary embodiment, the sealing strip 7 can be vented to a vacuum instead of venting to the atmosphere. In this case, the second outlet opening of the 3/2-way valves 19 is to be connected to the suction line of a vacuum source. The venting to a vacuum causes the sealing strip 7 to be ready to go faster.

In einem weiteren Ausführungsbeispiel kann anstelle der Teile 8; 9 und 10 nur ein um die obere rechte und untere rechte Ecke der Türöffnung herumgezogener Teil angeordnet werden. Die Anordnung von nur einem vertikalen Teil und einem drei Seiten umfassenden Teil wirkt sich vorteilhaft auf den Aufwand an Steuerungsmitteln aus.In a further embodiment, instead of the parts 8; 9 and 10, only a part drawn around the upper right and lower right corners of the door opening can be arranged. The arrangement of only one vertical part and one part comprising three sides has an advantageous effect on the expenditure on control means.
