<p>The device for controlling the rotation of any element essentially comprises a driven shaft (1) with slideways (2, 3, 4) radially integral with this shaft, and a driving shaft (6) driven by a geared motor unit (M) and comprising the same number of arms (7, 8, 9) carrying wheels (7a, 8a, 9a) as there are slideways on the driven shaft (1) to which the element to be controlled is connected. The device of the invention makes it possible, for example, to control the opening and closing of a door (14) with mechanical locking in the open and closed position of the door. <IMAGE></p> |
