DOOR LOCK WITH CONTROLLED OPERATION OF HANDLE Russian patent published in 2009 - IPC E05B47/06 

FIELD: construction.

SUBSTANCE: door lock comprises latch, guide block for latch motion and working axis, on both ends of which it is possible to install the drive for guide block actuation, so that possibility is created to transfer effort from every side of lock to guide block via movable connection elements, which are controlled by solenoid structure or similar. Guide block is equipped with two separate torsion devices, which are installed on working axis on different sides of guide block and fixed to it with the possibility of turn. To transfer effort, torsion devices may be connected to guide block via connection elements. Lock comprises selector element, which is shifted from one side of lock to the other and which retains torsion device selected in every case against turn relative to guide block so that it is possible to selectively switch on or off effort transfer from working axis to guide block by means of connection elements under solenoid control.

EFFECT: creation of simple and reliable design of lock, which may always be used on one side of door, at that application of lock on other side of door is selectively controlled.
