Abstract
Landing gears of support devices for articulated vehicle trailers are frequently left in neutral position while the articulated vehicle is being driven. The vibrations which occur during driving can cause the landing gear to descend unintentionally, touch the ground and be damaged. The invention provides a support device with a landing gear which is reliably prevented from descending. To this end, the toothed ring of the input shaft ( ) has two longitudinal sections ( ) of different diameters while having constant tooth spacing throughout. The tooth length in both sections ( ) is dimensioned in such a way that in neutral position, the input shaft ( ) can rotate while the toothed wheel ( ) remains stationary but is prevented from rotating while the input shaft ( ) remains stationary.
