| 摘要 |
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).
