Abstract: An electric lock with magnetic support of the coupling element, comprising a locking element engaging a selvage, a decoding assembly for a code bearing component, an actuation element, connected to an internal handle and associated with the locking element, and a second actuation element, connected to an external handle and coupled to the locking element by way of an electromechanical device. The actuation element comprises a stem connected to the external handle with a rotating plate and a contrast plate, at an end resting freely on a rotatable sleeve, coupled to the locking element and provided with notches; an electric motor and a slider, aligned with the notches actuatable to perform translational motion, and a magnet supporting a coupling element adapted to enter the notches to rigidly couple to each other the plate, the contrast plate and the sleeve.

Abstract: An electric lock with multiple-function spring, with a locking element, a decoding assembly for a code bearing component, a first actuation element connected to an internal handle, and a second actuation element connected to an external handle both coupled to the locking element by an electromechanical device; the second actuation element comprises a protruding stem that ends with a rotating plate, a rotatable contrast plate that rests freely on a rotatable sleeve coupled to the locking element, the plates and the sleeve being provided with respective notches; the electromechanical device has a motor with a worm screw on its shaft, a slider, coupled to the screw through a spring with one end fixed on the lock body, the central portion engaged on the slider, and the opposite end accommodated between two crests of the screw, and a coupling element for entering notches to couple plates and sleeve.

Abstract: A latch-and-bolt lock with simultaneous actuation of the bolt and of the latch during closure, the latch and the bolt being actuated by an elastic element so as to protrude from the lock in order to engage in respective selvages of the jamb, the lock including; a sensor for detecting a closed position of a door wheron the lock is fitted, the sensor being movable at right anles to a faceplate of the lock between an external position and an internal position relative to the lock and being retained in the internal position by abutment against the doorjamb; a slider which is guided parallel to the latch; a plate for blocking the bolt, which is guided transversely to the slider; a lever which is articulated to the slider and has a first arm which is operatively associated with the sensor and a second arm which is adapted to assume a position for blocking the latch when the sensor and the latch are inside the lock, a member for the actuation of the plate being arranged on the slider and being such that when the lat

Abstract: Lock comprising a spring-latch and a bolt, the spring-latch being actuatable against the biasing action of a spring by means of an external lever (knob) or an internal lever (handle), the levers being rotationally rigidly coupled to respective coaxial hubs rotatably supported at the sides of an element for opening the spring-latch which is pivoted coaxially to the hubs and is intermediate thereto; the lock further comprises teeth for pulling the element defined on the hubs, the teeth being able to pull the element only in the direction for opening the spring-latch by actuating one of the levers, a spring for the elastic return of the hubs when the levers are released which acts on tabs of the hubs with the interposition of a block guided tangentially to the hubs; the block can be orientated and is shaped so as to provide abutment only to the tab of the hub to which the inner lever is rigidly coupled.

Abstract: The cylinder lock and key comprises at least two auxiliary pins which are arranged on opposite sides with respect to the key slot and have an end which protrudes into the slot. The opposite ends of the two auxiliary pins cooperate with respective auxiliary tumbler pins which are actuated by springs and are suitable for being actuated in the position for rotation of the plug by a lever articulated in an opening of the shank of the key when the key is fully inserted in the lock.

Abstract: The cylinder lock comprises a plug and auxiliary pins which are disposed in seats, provided on the plugs and arranged laterally to the channel of introduction of the key. On introducing the key into the lock the pins are displaced from their seats such that, when the key is not the right one, they will engage into recesses on the outer casing of the lock, thus inhibiting rotation of the plug. By intervening on the pins it is also possible to obtain a set of hierarchically different locks for fabricating master key systems.

Abstract: A cylinder lock with key, incorporating a picking preventing means, comprises a plug mounted rotatably within the cylindrical seat of a lock cylinder and has a first set of holes lying on a radial plane. The holes accommodate pins which cooperate with tumbler pins accommodated in a second set of holes formed in the cylinder and being aligned with the first set of holes. A longitudinal key slot extends through the plug which is in communication with the first set of holes and has a longitudinal rib arranged to project thereinto to provide support for the pins. The rib conceals the ends of the pins resting thereon, and defines an intersection of the longitudinal key slot with the cylindrical portions of said first set of holes accommodating said pins. One of the pins has the same length as the hole accommodating it, thereby if deceitfully shifted, it will unavoidably engage the hole of the respective tumbler pin and produce a locked condition of the lock.

Abstract: An intrusion detector device for signalling undue opening of doors and closing-wings in general. The device is housed in a cavity of the door jamb and comprises means for supporting an alarm controlling switch and an element swinging supported and retained in an inoperative position by elastic means, said element being engageable by a lock bolt or pin projecting from the door when an undue force is exerted on the door, thus causing said element to rotate in an operative position in which said switch actuates an alarm.
