ABSTRACT:
A mechanical system constituting a modular driving unit for the programmed displacement of a mobile structure with respect to a reference bearing plane, the structure remaining parallel to itself. The mechanical system includes a frame formed by at least two lateral sides connected together. The frame is fast with the mobile structure. There is a principal upright articulated on the frame by a first end, with the second, opposite end resting on said reference bearing plane. There is also a maneuvering jack articulated by one end on the frame and by the opposite end on the second end of upright. Maneuver of the jack allows the angular displacement of the upright. The assembly of the upright and the jack constitutes with the frame a deformable triangle. A transmission assembly is borne by the frame and is constituted: (i) by a longitudinal shaft located in a plane parallel to the plane of displacement of the jack (ii) by a transverse shaft at right angles to the longitudinal shaft, and (iii) by a pinion controlling maneuver of the jack, the two shafts being kinetically connected together and connected to the pinion.
