Security locking device

A cylinder-type lock has sensors (for example proximity sensors) 20 mounted above tumblers 17, the outputs of the sensors being connected to a microprocessor (not shown). The correct key 30 produces a specific pattern of signals from the sensors 20 as it is inserted into the passageway 16 due to its distinct profile, and this pattern of signals is compared with a pattern preprogrammed into the microprocessor, to produce an output only if the two patterns of signals agree. The output of the microprocessor may, for example, be connected to an alarm system which is normally activated, but which is de-activated in response to an output from the microprocessor. Thus, even if the lock is picked or forced, the microprocessor will not product an output and the alarm will therefore remain activated such that it sounds when the door in which the lock is mounted is opened. Disk tumbler arrangements may be employed and the output can be used to disable a vehicle ignition. ...

A lock cylinder with plate or wafer tumblers

A cylinder lock-key combination a key for said lock and a method of manufacturing the key

The cylinder lock utilizes two bit-sprung sliding locking pins to control the rotation of a rotor in a stator. The rotor incorporates an axial rectangular section key way. An edge of each pin tip is contacted by the key (2) which has an 'L' section with the top bar face (2c) shaped to form a trapezoidally undulating coded longitudinal profile. The troughs (2c') of the key profile correspond to pin positions which liberate the rotor, and the trough sides(2c") are concavely curved in views normal to the major key plane. The system may develop to provide two sets of pins straddling an inverted 'T'-section key.
