Abstract

This structure is characterised in that it is formed from a rigid lower frame (1) bearing on the ground or on any framework, and from an upper frame (2), likewise rigid, connected to the lower frame by a central device (9) in the form of a motorized and deformable parallelogram on the one hand, and by lateral holding and support units (3-4-5-7) articulated between the two frames on the other hand; these transmission mechanisms being combined with each other in order to obtain the height displacement of the upper mobile frame with respect to the lower fixed frame (1) in a uniquely vertical direction. <IMAGE>
