The invention relates to a lamella system (1), arranged on a foundation of posts (5) and rails (6). The planar elements (2, 2') are set in motion by a particular mechanism, such that the individual planar elements (2, 21) can be independently pivoted individually or in groups (4, 4') with an opening angle (a) of between 0 and about 140°. |
