<p>The invention relates to door locking devices for office spaces, housings, safes etc. The inventive device comprises a key, a body provided with a keyhole, a reciprocally displaceable sliding member, a locking mechanism and at least one locking bar. The sliding member and a key pusher interact with a control unit. A key slot is embodied in the sliding member in such a way that it is located in front of the keyhole. The sliding member is arranged in such a way that it covers the keyhole when said sliding member interacts with the control unit. The locking mechanism is embodied in the form of two, fixed and movable with respect to the body, interacting locking units. The fixed locking unit is provided with code projections corresponding to the code holes and/or recesses embodied on the key. The pusher is arranged in such a way that the key is enabled to be displaced, while opening the lock, from the sliding member slot to a position of contact with said code projections. The movable locking unit is mounted in such a way that it interacts with at least one girder by means of the control unit. Said invention makes it possible to improve the service functions of the device by excluding the non-authorised access of the lock encoding elements and the use of counterfeit keys.</p> |
