Abstract: A motorized security locking system which is intended to be placed on the door of a high security enclosure and whose operation is reliable and more compact. The motorized security locking system includes: a case (1); a sliding bolt (3) movable in translation between an “in” position and an “out” position, and including a front end face (37), a back end face (39), two lateral faces (41), first (43) and second (45) longitudinal faces; and a controller (5) for controlling the movement of the sliding bolt, and including a motor (21), an actuator for actuating the motor, and a cam and a lever (25, 27), for connecting the motor to the sliding bolt, to transmit the drive force from the motor (21) to the sliding bolt (3) and to assure the movement thereof. The motor (21) is a motor with a single rotational direction.

Abstract: A drive device for locking a conditionally opening lock, including a motor means (MT) comprising a drive element (36) having an axis of rotation (X1), a transmission arm (26) mounted about an axis of rotation (X2) distinct from the axis (X1), a locking block (PVI) connected mechanically to the arm (26) and adapted to occupy an active position (P1), to oppose the displacement of a bar, and an inactive position (P2) allowing displacement thereof, and elastic means (48) for putting the locking block (PVI) under bias, when the block's displacement is impeded by the bar, wherein the elastic means (48) are arranged between the drive element (36) and the transmission arm (26), these elastic means (48) being in direct driving contact with a coupling surface (54) of the transmission arm (26).
