Claim:
Shutter device comprising one or more guide tracks ( 7 , 8 ) having a longitudinal direction, transmission means ( 5 , 6 ) and a shutter ( 1 ) with side edges ( 9 , 10 ), the device being designed to close off an opening ( 3 ), or any other aperture, by displacing the shutter ( 1 ) relative to the one or more guide tracks ( 7 , 8 ), whereby said transmission means ( 5 , 6 ) cooperate with the guide tracks ( 7 , 8 ), and are displaceable in the longitudinal direction of the guide tracks, are connected directly to and between the respective side edges ( 9 , 10 ) of the shutter ( 1 ) and the guide tracks ( 7 , 8 ) such that when a certain force is exerted on the side edges ( 9 , 10 ) of the shutter ( 1 ) in a direction transverse to the longitudinal direction of the guide tracks ( 7 , 8 ), the side edges ( 9 , 10 ) are separated at least partially from the transmission means ( 5 , 6 ), whereby the transmission means comprise a substantially continuous strip ( 19 ) extending substantially along the entire length of the side edges ( 9 , 10 ) of the shutter ( 1 ).
