<p>The apparatus has lifting mechanisms (2, 3) controlling displacements of a vault element (1) i.e. bulged dome, with respect to a skylight frame. Stabilization units stabilize the element in displacement, by balancing between opposed sides of the element using cables that describe effort demultiplier circuits during displacement of the element. The units have straight and horizontal lateral sides (4, 5) that are driven by deployable mechanisms i.e. articulated rod mechanisms (16) of the mechanisms (2, 3).</p> |
