Abstract (en)

[origin: CA2797884A1] The lift shaft door unlocking mechanism operates with expander skates (4) on the door drive (3) which unlock the lift shaft door when entering the region close to an access level. A particular feature is that these expander skates (4) on the lift cabin door drive are designed to be flexible with respect to the lift cabin (1) such that, in the event of any touching of the lift shaft head at the upper end of the lift shaft, they are flexible over an adjustable distance, and, after the lift cabin (1) moves away from the lift shaft head (2), they assume their original position again. For this purpose, these expander skates (4) are displaceably mounted on the expander skate construction itself along respective guides (11). Here, they are held in the uppermost displacement position by means of tension springs (9), and can be displaced downwardly against the force of these springs (9) through application of force to their upper ends from above resulting from a collision with the lift shaft head. After their upper ends have been released, they are returned to the uppermost displacement position again by means of these springs (9).
