<p>Dual-bolt high-security lock with an electric motor, comprising in combination: a) a freely rotatable geared motor (3) fixed to the bolt shank (2) and secured by means of its axle (4) to a toothed pinion (5) meshing with a rack (6) fastened to the faceplate (7) of the lock; b) a key entry barrel (15) fixed to a plate (19) secured to the faceplate (7) by means of a plate (21) and extended in its lower part by two hollow cylindrical bearing surfaces (27) and (28) holding a driving plate (14) provided with an oblong central orifice for the passage of the end of the key and with two studs (16) and (16') positioned at its edge symmetrically in relation to its centre, one of these studs (16) being positioned in proximity to a finger (13) terminating the bolt shank (2), in such a way that the key rotating in the barrel (15) drives the plate (14) in rotation and the stud (16) in proximity to the finger (13) drives the latter, thus causing the displacement of the bolts (1-1'). <IMAGE></p> |
