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).

Flexible shutter system combined with a drive system 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,
- wherein the shutter (1) has at least one area of low resistance (11), 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),
- wherein the area of low resistance (11) contains at least two tapes (42, 43) which are engageable with each other by least one slider (49, 50, 51),
- whereby at least one point of commencement (44) of breakage of the area of low resistance (11) is provided where the tapes (42, 43) cannot interlock over a certain part of their length.
Flexible shutter system combined with a drive system 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,
- wherein the shutter (1) has at least one area of low resistance (11), which, in the closed position, extends from a 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),
- wherein the area of low resistance (11) contains at least one zip having two tapes (42, 43) and teeth which can engage in each other by a zip slider (49, 50, 51);
- wherein the zip (39, 40, 41) is provided with at least one point of commencement (44);
- and
- wherein the teeth of at least one of said tapes (42, 43) have been removed at least in part at the point of commencement (44).
Flexible shutter system combined with a drive system 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,
- wherein the shutter (1) has at least one area of low resistance (11), which, in the closed position, extends from a 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),
- wherein the area of low resistance (11) contains at least two tapes (42, 43) which can engage in each other by at least one slider (49, 50, 51);
- wherein systems are provided to place the slider (49, 50, 51) in a parked position so that the tapes of the closure (39, 40, 41) can be separated in their entirety;
- and
- wherein the teeth of one of said tapes (43) extends beyond the teeth of the other tape (42) so that the slider (49, 50, 51) can be placed in said parked position on the first tape (43).
Flexible shutter system combined with a drive system 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,
- wherein the shutter (1) has at least one area of low resistance (11) , which, in the closed position, extends from a 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),
- wherein the area of low resistance (11) contains at least two tapes (42, 43) which can engage in each other by at least one slider (49, 50, 51);
- wherein an automatic closure systems are provided, allowing automatic closure of the access aperture;
- and
- wherein the automatic closure system includes at least one elastic connection (31, 32) connecting the edges (15, 16) of the area of low resistance (11) in such a way as to return said edges (15, 16) to the plane of the shutter (1).
Flexible shutter system combined with a drive system 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,
- wherein 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),
- wherein the area of low resistance (11) contains at least two tapes (42, 43) which can engage in each other by at least one slider (49, 50, 51);
- wherein the shutter has at least one stiffener (37, 38), extending approximately across the direction of movement of eth shutter (1) between the area of low resistance (11) and at least one side edge (2, 3) of the shutter (1);
- and
- wherein said stiffener (37, 38) extending from one side edge (2, 3) of the shutter (1) at the location of the area of low resistance (11) is connected to, but detachable from, a corresponding stiffener (37, 38) extending to the other side edge (3, 2) of the shutter (1).
