<p>A Venetian blind (1) is accommodated within the sealed interspace (5) defined by two glass surfaces (7,8) of a glass-box (6), the glass surfaces being spaced apart by an aluminum frame (4) which contains a molecular sieve (10). The Venetian blind is provided with control members (12-37) which allow adjustment of packing and/or inclination of its blades (2) from outside the glass-box (6) without altering the seal, and therefore the functionality, of the same. Operation from the outside of the control members inside the glass-box is achieved, for each adjustment, by magnetic coupling, through one of the glass surfaces of the glass-box, between a first magnet (22,32), positioned inside the glass-box and directly connected to the respective control system, and a second external magnet (23,35).</p> |
