摘要:
The present invention concerns an anti-intrusion device (1) for doors and windows comprising: - A barrage element (2) and support means (3) for holding the barrage element (2) opposed to the door or the window in such a way as to impede the opening of such door or window. In accordance with the invention, the device (1) further includes: - A winder (5) placed in use above the barrage element (2) and; - At least one tape (10) connected to the barrage element (2) on one side and to the winder (5) on the opposite side in such a way that a rotation of the winder (5) in a direction causes a winding of the tape (10) on the winder (5) and a rotation in the opposite direction causes an unwinding of the tape (10) from the winder (5) with relative lowering of the barrage element (2) on the support means (3) for causing the block of the door. Further, the winder (5) comprises an electric motor (6) and a rotating shaft (7) connected to the motor (6), the rotating shaft (7) being provided with at least one pulley (8) on which to wind/unwind said tape (10).
