Abstract (en)
[origin: WO2020126429A1] The invention relates to an elevator system (1) having an elevator car (3) and a laser distance-measuring device (21). The elevator car (3) can be moved along a travel path (13), which is delimited at the top by an upper boundary (17) and at the bottom by a lower boundary (19). The laser distance-measuring device (21) is configured to emit a laser beam (27) and to determine a distance to a position at which the laser beam (27) impinges on an object. The laser distance-measuring device (21) is mounted on the elevator car (3) and configured such that in a first configuration the laser beam (27) can be directed upward to the upper boundary (17), and in a second configuration can be directed downward to the lower boundary (19). As a result, a current position of the elevator car (3) can be determined in a redundant manner. Furthermore, in a third configuration, lateral distances to boundary marks (35) can be measured in order to be able to read out information that is codified by the boundary marks (35).
