Embodiment Construction

[0066] figure 1 a shows a first arrangement for repositioning an elevator car 3 from a first elevator shaft into a second elevator shaft in the elevator system 1 according to the invention. The elevator system 1 comprises a plurality of elevator cars 3, only one of which is shown here. The elevator car 3 is movable in a plurality of elevator shafts 2 .

[0067] During the vertical movement, the elevator car 3 is guided by means of the first vertical guide rail 4 . The vertical guide rail 4 comprises a fixed vertical rail section 6 which is rigidly fastened to the shaft wall 14 of the elevator shaft 2 . Moreover, the vertical guide rail 4 includes a rotatable rail segment 5, such as figure 1 As shown by the solid lines of , it is assumed that these rotatable rail segments 5 are positioned in a vertically aligned position. Guide rollers 12 roll on the rail sections 5 , 6 . The guide rollers 12 are fastened to a frame 16 which is movable along the rails 4 , 8 . The elevator...

Abstract

The invention relates to a drive unit (20) for an elevator system. The drive unit (20) comprises a first interface (47, 17, 31) for at least indirectly fastening a rotatable rail segment (5) to the drive unit (20) and a second interface (24, 18) for at least indirectly fastening the drive unit (20) in the elevator shaft (2).

Description

technical field [0001] The invention relates to a drive unit for an elevator system and to an elevator system comprising such a drive unit. Background technique [0002] So-called multiple elevator systems comprise two elevator shafts, wherein in each elevator shaft there is at least one first vertical guide rail for vertically guiding the elevator cars. A plurality of elevator cars are provided, which move independently of each other along the first guide rail in the elevator shaft. The first guide rail comprises at least one rotatable rail section which can be shifted by means of a drive unit from a vertically aligned position, in particular to a horizontally aligned position deviating from the vertically aligned position, so that the elevator car can pass through, in particular, a horizontal second The guide rails are transferred from the first elevator shaft to the second elevator shaft. The elevator car is guided on the first and second guide rails by means of guide r...
