Abstract

According to the invention, the maintenance scaffold (10) is assembled as follows: in a first step, an illuminated ceiling, which lies below the collapsed maintenance scaffold (10), is taken down. Suspension members (17) are then brought into a vertical position. The platform (12) and flap (13) are lowered vertically until they reach the bearings (19) of the suspension members (17). Before mounting the platform (12), the maintenance personnel must unfold the ladder (18) and open the flap (13) upwards. Once the personnel has mounted the platform (12), the flap is closed (13) by means of a handle, in such a way that the entire platform can be used as a working scaffold. With the maintenance scaffold (10) in the working position, the height for a regulatory passage (U) is maintained, as determined by the distance between the cabin ceiling (14) and the platform (12).

The invention, as characterized in claim 1, achieves the object of avoiding the disadvantages of the known device and of providing a device for working in an elevator shaft which does not pose a danger to maintenance personnel or to elevator users in the elevator car. The advantages achieved by the invention can be seen essentially in the fact that for the
Aufzugskabinenbenutzer keine Gefahr besteht, sich an Teilen der Wartungsbühne zu verletzen, weil die Wartungsbühne sich ausserhalb des Aufenthaltsbereiches d.h. oberhalb der Kopf öhe der Aufzugskabinenebenutzer befindet. Ausserdem gibt es an den Kabinenwänden keine Angriffspunkte für Vandalismus wie beispielsweise Kanten, Scharniere, Fugen, etc.. Das Kabineninterieur wird durch die Wartungsbühne nicht beeinträchtigt. Verkaufsstrategisch ist die ästhetische Aufmachung des Kabineninterieurs von grosser wirtschaftlicher Bedeutung. Die erfindungsgemässe Wartungsbühne kommt dieser Forderung beispielsweise durch die unsichtbare Anordnung unter der Leuchtdecke oder durch eine fugenlose Einpassung der Wartungsbühne in der Decke voll und ganz entgegen. Die Decke ist bei Wartungsarbeiten vor Verschmutzung und/oder Beschädigung geschützt. Das Unterhaltspersonal betritt nur die während des normalen Fahrbetriebes unsichtbare Oberseite der Decke. Die erfindungsgemässe Wartungsbühne hat auch eine erhöhte Tragfähigkeit, sodass im Schacht zu montierende oder demontierte Teile auf der Wartungsbühne zwischengelagert werden können. Die Lage der Luke bzw. der Deckenöffnung im Dach der Aufzugskabine zur Ausführung der Arbeiten imElevator car users are not at risk of injuring themselves on parts of the maintenance platform, because the maintenance platform is outside the lounge area, i.e. the elevator car user is above the head. In addition, there are no points of attack for vandalism such as edges, hinges, joints, etc. on the cabin walls. The cabin interior is not affected by the maintenance platform. In terms of sales strategy, the aesthetic appearance of the cabin interior is of great economic importance. The maintenance platform according to the invention fully meets this requirement, for example, by the invisible arrangement under the light ceiling or by a seamless fit of the maintenance platform in the ceiling. The ceiling is protected from dirt and / or damage during maintenance work. Maintenance personnel only enter the top of the ceiling that is invisible during normal driving. The maintenance platform according to the invention also has an increased load-bearing capacity, so that parts to be assembled or dismantled in the shaft can be temporarily stored on the maintenance platform. The position of the hatch or the ceiling opening in the roof of the elevator car to carry out the work in
Aufzugsschacht kann so gewählt werden, dass die Luke nicht von im Schachtkopf angeordneter Schachtausrüstung überragt wird, wobei die Wartungsbühne in der Projektion der Luke liegt und ausserdem eine ausreichend grosse Standfläche hat. Die Lage der Luke, die ausreichende Standfläche und die erhöhte Tragfähigkeit der Wartungsbühne gewährleisten die Sicherheit des Unterhaltspersonal.The elevator shaft can be selected so that the hatch is not surmounted by shaft equipment arranged in the shaft head, the maintenance platform being located in the projection of the hatch and also having a sufficiently large footprint. The position of the hatch, the sufficient footprint and the increased load capacity of the maintenance platform ensure the safety of maintenance personnel.

The ceiling 14 is in itself 5 and 6. A spring 33 engages the articulated arm 30 of the cover 22 and is connected at the other end to a support 34. Support 34 and cabin frame 32 are connected by means of a strut 35. The force of the spring 33 is such that the maintenance platform 10 can be raised with a small force and brought into the rest position. The maintenance platform 10 can be equipped on one or both sides with articulated arms 30, spring 33, support 34 and strut 35.
In einer weiteren Ausführungsvariante wird die Deckenöffnung 15 von einem Deckel abgeschlossen, der einen Teil der Decke 14 bildet und gleichzeitig als Podest 12 verwendbar ist. Bei Arbeiten im Aufzugsschacht 1 wird der Deckel von der Decke 14 manuell gelöst und beispielsweise auf die an gegenüberliegenden Wänden angeordneten Handläufe aufgelegt und falls nötig mittels Stützen in der Höhe angepasst.In a further embodiment variant, the ceiling opening 15 is closed off by a cover which forms part of the ceiling 14 and at the same time as a platform 12 is usable. When working in the elevator shaft 1, the cover is manually removed from the ceiling 14 and, for example, placed on the handrails arranged on opposite walls and, if necessary, adjusted in height by means of supports.
In einer weiteren Ausführungsvariante können die Wartungsbühne oder Teile der Wartungsbühne beispielsweise auch in einem Schrank neben einer Schachttür untergebracht sein. Zum Arbeiten hängt oder stellt sie dasIn a further embodiment variant, the maintenance platform or parts of the maintenance platform can, for example, also be accommodated in a cupboard next to a shaft door. She hangs or puts it to work
Unterhaltspersonal in die Kabine und verstaut abgenommene und für den Aufbau der Wartungsbühne nicht notwendige Teile beispielsweise im selben Schrank.Maintenance personnel in the cabin and stowed away parts that are not necessary for the construction of the maintenance platform, for example in the same cupboard.
Die gezeigte maschienenraumlose Aufzugsdisposition bietet mit ihrem verkürztem Schachtkopf 3 für die Wartung vom Kabinendach aus nicht genügend Höhe H für eine vorschriftsmässige Überfahrt (Distanz zwischen KabinendeckeWith its shortened shaft head 3, the machine room-less elevator disposition shown does not offer sufficient height H for maintenance from the cabin roof for a proper crossing (distance between cabin ceiling
14 und Schachtdecke 21) von beispielsweise einem Meter. Mit der erfindungsgemässen Wartungsbühne 10 in Arbeitsstellung wird die geforderte Überfahrt Ü erreicht, weil nicht mehr die Distanz zwischen der Kabinendecke 14 und der Schachtdecke 21 bestimmend ist, sondern die Distanz zwischen dem Podest 12 und der Schachtdecke 21 und weil keine Schachtausrüstung im Schachtkopf 3 die Deckenöffnung14 and manhole cover 21) of, for example, one meter. With the maintenance platform 10 according to the invention in the working position, the required crossing U is achieved because it is no longer the distance between the cabin ceiling 14 and the shaft ceiling 21 that is decisive, but rather the distance between the platform 12 and the shaft ceiling 21 and because no shaft equipment in the shaft head 3 determines the ceiling opening
15 überragt . 15 towers.
