Abstract (en)
Device for motorising the locking mechanism of doors with linear, perimetric bolts, consisting of a frame comprising an endless screw driven by two DC electrical motors. The displacement of the bolt driven by the endless screw causes the rotation of a drive arm which causes, in turn, the rotation of a driven arm. In the anti-break-in version, the arms are secured to one another by the core of an electromagnet, the coil of which, when supplied with power, separates the two arms, while, in the anti-panic version, the driven arm, totally separated from the drive arm, is equipped with a return spring which is tensioned by an electromagnet, the supply of which only needs to be switched off in order to unlock the door. <IMAGE>
