The invention relates to an electronic device (1) configured for opening/closing a door (P) or similar, from a light signal defining an opening and/or closing code emitted by a movable transmitter having means for emitting said light signal, said electronic device having an electric lock comprising: a lock cylinder (2) with a stator (20) and a rotor (21), as well as an electric actuator (3) configure to modify the state of the electric lock, means for receiving signals configured to detect light pulses comprising a receiving diode (4), a control unit (5) connected to the receiving diode (4) and connected to the electric actuator (3), configured to decode the light pulses detected by said receiving means and to determine a control of the electric actuator (3).

According to the invention, the diode (4) is advantageously protected and all of the means (3, 4, 5) are self-supporting with the lock cylinder (2) in order to facilitate the installation of it as a conventional lock cylinder.

The invention relates to an electronic padlock cover with a knob, wherein the padlock includes a rotor assembly formed by an electronic cylinder joined in continuity to an electronic knob, a body wherein the cylinder and a padlock ring are housed, wherein the cover includes a protective casing of the body intended to surround and protect the body of the padlock on one end, a support with a ring-shaped configuration including two grooves and an extension, centered on each groove, which includes a pair of first holes for the introduction of corresponding fastening screws for fastening to the body of the padlock and a protective casing of the knob including two flanges located in correspondence with the grooves, including an inner cylindrical opening for the housing of the knob.

Systems and apparatuses include a lock including a shackle movable between an unlocked state and a locked state, an electronically actuated blocker selectively engaged with the shackle to inhibit movement of the shackle from the locked state to the unlocked state, the blocker movable between a key override disabled position, a key override enabled position, and an electronic unlock position, and a key cylinder structured to move the shackle to the unlocked state when the blocker is in the key override enabled position.

Electromechanical lock. Actuator (103) comprises drive head (109) rotatable by electric power (160). Access control mechanism (104) comprises driven gear (101) with cogs, and grip mechanism (111). Drive head (109) comprises two pins (210, 212) configured and positioned so that one of pins (210, 212) is in notch between two cogs (220, 222, 224, 226, 228) of driven gear (101). For opening, drive head (109) rotates driven gear (101) to open position (400), by two pins (210, 212) driving cogs (220, 222, 224, 226, 228) and overcoming grip mechanism (111), and thereby setting access control mechanism (104) to be rotatable (152) by user. If external mechanical break-in force (172) is applied, drive head (109) remains stationary by at least one of pins (210, 212) contacting at least one of cogs (220, 222, 224), and by grip mechanism (111) holding driven gear (101) stationary in locked position (200).

Electromechanical lock utilizing magnetic field forces. An actuator is moved (1202) from a locked position (260) to an open position (400) by electric power. In the locked position (260), a permanent magnet arrangement directs (1204) a near magnetic field to block an access control mechanism to rotate, and simultaneously the permanent magnet arrangement attenuates (1206) the near magnetic field towards a far magnetic break-in field originating from outside of the electromechanical lock. In the open position (400), the permanent magnet arrangement directs (1208) a reversed near magnetic field to release the access control mechanism to rotate, and simultaneously the permanent magnet arrangement attenuates (1210) the reversed near magnetic field towards the far magnetic break-in field.

A motorized deadbolt cylinder assembly includes a housing having a generally cylindrical side wall, a generally planar outer end wall disposed at a first end of the side wall and a generally planar inner end wall disposed at a second end of the side wall opposite to the first end. The assembly also includes a motor disposed within the housing, the motor having a drive shaft, and a cam arranged on the inner end wall and arranged such that at least a portion thereof is disposed outside of the housing. A gear train is operably connected between the drive shaft of the motor and the cam such that rotation of the drive shaft of the motor causes rotation of the cam, such that the cam rotates with an increase in mechanical advantage as compared to rotation of the drive shaft of the motor.

Various embodiments that pertain to signal based arrangement of pin tumbler pins are described. A receiver can receive and process a signal. The signal can indicate an arrangement for the pins of the pin tumblers. With a proper signal, the pins can be placed so that the pin tumbler unlocks. Security measures can be put into place to make sure the signal is a valid signal, such as through employment of a hash function set (e.g., two hash functions).

An intelligent unlocking device comprises a rear shell, a front shell, a motor assembly, a hollow rotating shaft, an adapting piece connected with a lock cylinder and the hollow rotating shaft, a manual rotating shaft, an inner bearing and a bearing support which are disposed around the manual rotating shaft, and an outer bearing. The bearing support and the outer bearing are disposed around an end of the manual rotating shaft. The intelligent unlocking device is silent and free of noises in use, and convenient to assemble and disassemble, intelligent unlocking can be achieved without replacement of a whole door lock, and costs are reduced for users.
