Abstract

A method for creating an elevator shaft for an elevator system, wherein the elevator shaft is oriented mainly vertically, uses a plurality of base modules placed on one another. The shaft is upwardly closed off by a top module and forms a travelway for a car of the elevator system. In a normal operation of the elevator system, the car is moved at a nominal speed within the travelway. According to the method, an intermediate element having an intermediate element height is arranged between an uppermost one of the base modules and the top module, wherein the intermediate element height is dependent on the nominal speed of the car.

First claim

The invention claimed is:

1 . A method for creating an elevator shaft of an elevator system, wherein the elevator shaft is vertically aligned and forms a travelway for a car of the elevator system, which car is moved at a nominal speed within the travelway in normal operation of the elevator system, the method comprising the steps of:
placing multiple base modules on each other forming a travelway section of the travelway of the vertically aligned elevator shaft; closing the elevator shaft upwards by mounting a top module along the travelway above the base modules, wherein a drive machine is arranged in the top module; providing a single intermediate element having an intermediate element height dependent on the nominal speed of the car, wherein higher nominal speed correlates to a greater intermediate element height; and arranging the intermediate element in the travelway exclusively between an uppermost one of the base modules and the top module, wherein the intermediate element is configured to form free space in a shaft head of the elevator shaft.

2 . The method according to claim 1 including determining the intermediate element height of the intermediate element dependent on a square of the nominal speed of the car.

3 . The method according to claim 1 including forming the intermediate element with a plurality of vertically oriented intermediate element supports.

4 . The method according to claim 3 including forming the intermediate element with the vertically oriented intermediate element supports connected by at least one horizontally oriented intermediate element cross member.

5 . The method according to claim 4 including forming at least one of the intermediate element supports and/or the at least one intermediate element cross member as a metal profile.

6 . The method according to claim 1 wherein each of the base modules has a door opening adapted for arranging a shaft door therein.

7 . The method according to claim 1 wherein the elevator system has a counterweight, a suspension means connecting the car and the counterweight, and a counterweight buffer arranged below the counterweight, wherein the counterweight buffer is adapted and arranged to limit a downward displacement of the counterweight and can be maximally compressed by the counterweight by a buffer stroke, and wherein the intermediate element height of the intermediate element also is dependent on the buffer stroke of the counterweight buffer.

8 . The method according to claim 1 wherein the intermediate element height of the intermediate element also is dependent on a presence of a limiting device in the elevator shaft, wherein the limiting device is adapted to, in a maintenance mode of the elevator system, limit a movement of the car in the travelway toward the top module.

9 . An elevator shaft of an elevator system, the elevator shaft being created by performing the method according to claim 1 , the elevator shaft comprising:
a plurality of the base modules vertically aligned; the intermediate element on top of an uppermost one of the base modules; the top module on top of the intermediate element; and wherein the base modules, the intermediate element and the top module form the travelway.

10 . An elevator shaft of an elevator system, wherein the elevator shaft is vertically aligned and forms a travelway for a car of the elevator system, which car is moved at a nominal speed within the travelway in normal operation of the elevator system, the elevator shaft comprising:
at least two base modules placed on each other forming a travelway section of the travelway of the vertically aligned elevator shaft; a single intermediate element having an intermediate element height dependent on the nominal speed of the car, the intermediate element exclusively being placed above and on an uppermost one of the base modules; and a top module being placed above and on the intermediate element completing the travelway and closing the elevator shaft upwards, wherein a drive machine is arranged in the top module; wherein higher nominal speed correlates to a greater intermediate element height; and wherein the intermediate element is configured to form free space in a shaft head of the elevator shaft.
