Title:
ELEVATOR ASCENDING/DESCENDING BODY DISPLACEMENT SUPPRESSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/003979
Kind Code:
A1
Abstract:
Provided is an elevator ascending/descending body displacement suppression device which makes it unlikely for a guide rail to warp due to the counterforce received from the ascending/descending body. A stopper unit (22) of this displacement suppression device (18) is provided to the ascending/descending body. The stopper unit (22) is provided with a stopper (26), a first drive unit (27) and a second drive unit (28). The stopper (26) faces a guide rail for guiding the ascending/descending body. The first drive unit (27) moves the position of the stopper (26) relative to the ascending/descending body in the direction in which the ascending/descending body travels. The first drive unit (27) causes the stopper (26) to face the guide rail restricting part (13). The second drive unit (28) changes the gap between the guide rail and the stopper (26) by moving the stopper (26). The second drive unit (28) suppresses displacement of the ascending/descending body via the stopper (26) which is separated from the guide rail restricting part (13) by a narrower gap.
