Abstract: An installation for covering and uncovering a surface includes a series of slats of adjustable inclination supported by pivot pins via a set having a first carriage and a second carriage. A movement system has, for each head slat, movement motors on board the first and second carriages. For the even-numbered slats, firstly a retractable coupling (A) is fastened between the first carriage of said slat and the first carriage belonging to the head slat or to the neighboring slat of lower number, and secondly a drive system (S) is provided for driving the second carriage of said slat in translation. For each odd-numbered slat that is present, a retractable coupling (A) is fastened between the second carriage of said slat and the second carriage belonging to the neighboring slat of lower number, and a drive system (S) is provided for driving the first carriage of said slat in translation.

Abstract: The invention relates to a unit for covering and uncovering a surface using adjustable slats (3), comprising: for each slat (3), a set of two carriages (101, 102) guided in translation along guide tracks (8); a system (II) for moving the slats (3), comprising two movement motors (12) for each carriage pair (101, 102) equipping a slat, each motor being mounted in a different carriage; a system (I) for orientating the slats (3), comprising at least one orientation motor (14) for each carriage pair equipping a slat, said at least one motor being mounted in at least one of the carriages; and a control device for moving at least part of the slats in translation and orientating said slats.
