The lift has a cage (5) in a shaft with at least one open side which has a facing in the form of a roller blind poster (7). This is fixed via a roller mechanism (9), on one side to the top (14) or bottom (11) of the shaft, and on the other side, to the cage. The blind rolls up and down as the lift cage travels. The roller mechanism may have a rotary (8) drum which can be pretensioned by spiral springs (23) towards its pivot axle (20). The pivot axle of a locking piece (22) can be clamped in any angular position. |
