Abstract

A top module for closing off an elevator shaft of an elevator system has a first top module side wall and a top module ceiling, a first guide rail piece fixed by a bracket on the first top module side wall, and a drive unit connected to the first guide rail piece. The top module can assume an operating state and a transport state. In the operating state, the first guide rail piece and the drive unit assume operating positions, and a car of the elevator system can be moved in the elevator shaft closed off with the top module. In the transport state, the first guide rail piece and the drive unit assume transport positions that deviate from the operating positions.

First claim

1 - 15 . (canceled)

16 . A top module for closing off an elevator shaft of an elevator system, the top module comprising:
a first top module side wall adjoining a top module ceiling; a first guide rail piece fixed to the first top module side wall by a bracket; a drive unit connected to the first guide rail piece; wherein the top module is adapted to be in a transport state prior to placement on the elevator shaft and is adapted to be in an operating state after being placed on the elevator shaft; when the top module is in the operating state, the first guide rail piece and the drive unit are in operating positions and in which a car of the elevator system is moved in the elevator shaft that is closed off with the top module; and when the top module is in the transport state, the first guide rail piece and the drive unit are in transport positions that deviate from the operating positions.

17 . The top module according to claim 16 a position of the bracket on the first top module side wall when the top module is in the operating state is identical to a position of the bracket on the first top module side wall when the top module is in the transport state.

18 . The top module according to claim 16 wherein, in the transport state of the top module, the drive unit is held by a holding bracket fixed to the top module.

19 . The top module according to claim 16 wherein the top module when in the transport state includes a displacement device for displacing the drive unit and the first guide rail piece relative to the first top module side wall.

20 . The top module according to claim 16 wherein the top module when in the transport state includes an alignment element holder adapted to hold an alignment element during an installation of the elevator system.

21 . The top module according to claim 16 including a second top module side wall opposite the first top module side wall and a second guide rail piece fixed to the second top module side wall by another bracket, wherein when the top module is in the operating state, the second guide rail piece is in an operating position and the car of the elevator system is moved in the elevator shaft that is closed off with the top module, and when the top module is in the transport state, the second guide rail piece is in a transport position deviating from the operating position of the second guide rail piece.

22 . The top module according to claim 21 wherein when the top module is in the transport state, the first and second guide rail pieces are arranged completely within the top module and spaced from a lower edge of the top module).

23 . The top module according to claim 16 wherein when the top module is in the transport state, a traveling cable of the car is arranged within the top module.

24 . The top module according to claim 16 wherein when the top module is in the transport state, a mounting platform extending parallel to the top module ceiling is arranged within the top module.

25 . The top module according to claim 16 wherein when the top module is in the transport state, a transport box accommodating installation material for the elevator system is arranged within the top module.

26 . A method for installing an elevator system having an elevator shaft to be closed off at a top with a top module, the method comprising the following steps:
providing the top module having a first top module side wall adjoining a top module ceiling, a first guide rail piece fixed to the first top module side wall by a bracket, and a drive unit connected to the first guide rail piece; wherein the top module is adapted to assume an operating state in which the first guide rail piece and the drive unit are in operating positions and a car of the elevator system can be moved in the elevator shaft closed off with the top module, and the top module is adapted to assume a transport state in which the first guide rail piece and the drive unit are in transport positions that deviate from the operating positions; bringing the top module into the transport state before placement on the elevator shaft; placing the top module on top of an unfinished part of the elevator shaft to close off the elevator shaft; and bringing the top module into the operating state after the placement on the elevator shaft.

27 . The method according to claim 26 including displacing the first guide rail piece and the drive unit from the transport positions along the first top module side wall into the operating positions to bring the top module into the operating state.

28 . The method according to claim 27 including during the displacement guiding the first guide rail piece by the bracket.

29 . The method according to claim 27 including during the displacement securing the drive unit against tilting by an anti-tilt protection.

30 . The method according to claim 26 including installing the top module ceiling after the first guide rail piece and the drive unit have been fixed on the first top module side wall.
