Abstract
This invention concerns a flexible shutter system combined with drive systems in such a way as to permit the shutter (1) to move vertically between a closed position and an open position, said shutter (1) being intended to close an opening (5) or other aperture, the shutter (1) having at least one area of low resistance (11) which, in the closed position, extends from the lower edge (4) of the shutter (1) to a certain height on the latter (1), in such a way as to permit the creation of at least one access aperture if the shutter (1) is broken at the location of said area of low resistance (11).
Claims20
Flexible shutter system combined with drive systems in such a way as to permit the shutter (1) to move vertically between a closed position and an open position, said shutter (1) being intended to close an opening (5) or other aperture, characterised by the fact that the shutter (1) has at least one area of low resistance (11), which, in the closed position, extends from the lower edge (4) of the shutter (1) to a certain height on the latter, to allow at least one access aperture to be created when the shutter (1) is broken at the location of said area of low resistance (11), characterised by the fact that the area of low resistance (11) contains at least two tapes (42, 43) which can engage in each other by means of at least one slider (49, 50, 51).
System in accordance with claim 15, characterised by the fact that the aforesaid electrical circuit (23) contains several contacts (24) which are connected in series.
