The proposed entraining equipment for the coupling, unlatching and entraining of shaft doors in lifts is a parallelogram, which is arranged to be movable laterally and actuated by the door drive on the cage, with two entraining members (1, 2). One entraining member (1) is firmly connected with a slide member (8), which slides in a guide (9) and is pushed into a neutral abutment setting by a compression spring (10) during the travel. A movable arresting coulisse (3), the upper parallelogram arm of which displays a pawl lever (6) with a pawl (12), is mounted on the entraining member (1). On travelling into a stopping place, the entraining equipment is pushed by the shaft door rollers (11, 21) into a position centred with respect to the shaft door rollers (11, 21) and, on the moving of the left- hand shaft door roller (21) onto the arresting coulisse (3), this is urged inwardly and the entire entraining equipment is arrested in the centred position by means of the pawl (12) engaging in between the teeth of a toothed comb (7). During travel, the compression spring (10) pushes the equipment again into a neutral initial position. For adjusting operations at the door drive from a storey, the arresting can be undone by means of an eccentric (18) to be actuated manually.
