Abstract
The invention concerns a shutter device (1) in particular for closing an aperture (3) or the like, by displacement of the shutter (1) relative to one or several guide paths (7, 8), wherein the transmission means (5, 6) co-operating with the guide paths (7, 8), are provided between the lateral edges (9, 10) of the shutter (1) and the guide paths (7, 8) such that when a certain tractive force transverse to the longitudinal direction of the guide paths (7, 8) is exerted on the lateral edges (9, 10) of the shutter (1), said edges (9, 10) are separated at least partly from said transmission means (5, 6).
Claims23
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).
