LOCKING MECHANISM FOR CYLINDER LOCK Russian patent published in 2008 - IPC E05B35/04 

FIELD: ironmongery, particularly coded mechanical and electromechanical locks to be opened by special keys, namely with pressure keys and special-purpose systems.

SUBSTANCE: locking mechanism comprises body, rotary axis with pressure pins connected to axis surface and flange with spring-loaded locking pins. Pressure pin ends pass into pressure key grooves. Locking pin ends pass in rotary axis orifices and are supported by pressure pin ends. Locking pins are spring-loaded with leaf spring having number of leafs equal to number of pins. Pressure key is made as thin-wall bush with blind longitudinal end grooves cooperating with corresponding support plates of pressure pins. Central bush orifice made in pressure key is adapted to be aligned with rotary axis. Pressure key has plate having lead projecting out of outer and inner key bush diameters.

EFFECT: elimination of non-authorized access to electronic circuits of instruments, as well as increased reliability, decreased size and extended field of application.
