Description

Die Erfindung betrifft eine Wartungseinrichtung für eine Aufzugskabine.The invention relates to a maintenance device for a Elevator car.

Heute werden im Aufzugsbau in den Aufzugskabinen Dachluken vorgesehen, die einerseits als Fluchtweg für in einem blockierten Aufzug eingesperrten Fahrgäste dienen oder andererseits von Servicemonteuren als Zugang auf das Kabinendach benutzt werden können.Today in elevator construction in elevator cabins Roof hatches provided, on the one hand, as an escape route for in serve passengers locked in a blocked elevator or on the other hand by service technicians as access to the Canopy can be used.

Beispielsweise aus der DE 171 424 ist eine Sicherheitseinrichtung für Aufzüge bekanntgeworden, bei der in der Decke und im Boden der Kabine durch Klappen verschliessbare Öffnungen vorgesehen sind. Durch diese Öffnungen können im Falle eines Brandes oder einer Betriebsstörung die Insassen entweder nach oben oder nach unten aus der Kabine aussteigen und unter Benutzung einer an der Kabine oder am Schacht befestigten Strickleiter ins Freie gelangen.For example from DE 171 424 Safety device for lifts became known at by flaps in the ceiling and floor of the cabin closable openings are provided. Through this Openings can be made in the event of a fire or Malfunction the occupants either up or down Get out of the cabin below and use a rope ladder attached to the cabin or shaft get outside.

Bei der oben beschriebenen Anordnung wird zum Ausstieg aus der Kabine eine Strickleiter verwendet, die ausserhalb der Kabine angeordnet ist. Eine Strickleiter ist jedoch nur für Notfälle gedacht und aufgrund ihrer fehlenden Stabilität für Servicearbeiten am Schacht oder an der Kabine untauglich. Ausserdem besteht bei der Benutzung einer freihängenden Strickleiter durch einen Monteur, wie auch durch in der Kabine eingeschlossene Fahrgäste, Absturzgefahr.With the arrangement described above it becomes an exit used a rope ladder from the cabin that is arranged outside the cabin. A rope ladder is, however, only intended for emergencies and because of their lack of stability for service work on the shaft or disabled at the cabin. There is also the Use of a free hanging rope ladder by one Fitter, as well as by enclosed in the cabin Passengers, risk of falling.

Deshalb muss bei den heute bekannten Aufzugskabinen der Servicemonteur entweder eine Leiter mitbringen, oder er muss über eine Schachttüre, die oberhalb der Position der Aufzugskabine ist, auf das Dach der Kabine gelangen, was ebenfalls nicht ungefährlich ist. Das Anbringen einer Leiter im Innern der Kabine würde das optische Erscheinungsbild trüben. Weiter könnte eine solche Leiter missbräuchlich verwendet werden. Es gibt aber auch Fälle, wo das Kabinendach aus statischen Gründen nicht betreten werden darf. Dann muss sich ein Monteur für Arbeiten am Kabinendach oder im Schacht auf andere Weise Zugang verschaffen.For this reason, the elevator cabs known today must have a Service technician either bring a ladder or he must have a shaft door that is above the position of the Elevator car is what get to the roof of the cabin is also not harmless. Attaching one Ladder inside the cabin would do the visual Tarnish appearance. Such a ladder could continue be misused. But there are also cases where for static reasons you do not enter the cabin roof may be. Then a fitter has to work on Canopy or shaft access in any other way procure.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Wartungseinrichtung für eine Aufzugskabine vorzuschlagen, welche die vorgenannten Nachteile nicht aufweist und einem Servicemonteur bei möglichst grosser Sicherheit Zugang zur Oberseite der Kabine und zu Schachteinrichtungen verschafft.The present invention is based on the object a maintenance device for an elevator car to propose which the disadvantages mentioned above are not and a service technician with the largest possible Security access to the top of the cabin and to Shaft equipment procured.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass an der Kabine selbst eine Leiter angeordnet ist, von der aus der Monteur die zu wartenden Einrichtungen auf dem Kabinendach erreichen kann, ohne das Kabinendach betreten zu müssen. Weil das Kabinendach keine hohen Belastungen mehr auszuhalten braucht, kann nun dessen Konstruktion vereinfacht, resp. in Leichtbau ausgeführt werden. Der Monteur befindet sich mit seinem Körper während der Wartungsarbeiten teilweise noch innerhalb der Kabine, deshalb besteht keine Absturzgefahr mehr und zugleich kann die Schachtkopfhöhe reduziert werden.The advantages achieved by the invention are in essential to see in that on the cabin itself a ladder is arranged, from which the fitter reach facilities to be serviced on the cabin roof can without having to enter the cabin roof. Because that Canopy can no longer stand high loads needs, its construction can now be simplified, respectively. be carried out in lightweight construction. The fitter is with his body partially during maintenance still inside the cabin, so there is none Risk of falling more and at the same time the shaft head height be reduced.

Durch die in den Unteransprüchen aufgeführten Massnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Anspruch 1 angegebenen Wartungseinrichtung für eine Aufzugskabine möglich. Durch die Ausführung als Teleskop- oder zusammenklappbare Leiter lässt sie sich sehr einfach und platzsparend in der Dachluke unterbringen. Weiter wird durch das Anbringen der Leiter an der Aussenseite der nach innen klappbaren Dachluke ein einfacher und schneller Dachzugang für die Wartung gewährleistet.By the measures listed in the subclaims are advantageous developments and improvements of Maintenance device specified in claim 1 for a Elevator cabin possible. Through the execution as a telescope or collapsible ladder it is very easy and save space in the skylight.
