LOCKING MECHANISM Russian patent published in 2009 - IPC E05B39/02 G09F3/03 

FIELD: construction.

SUBSTANCE: invention is referred to hardware. The locking mechanism includes rope piece with one end being passive and fixed in the housing. The second free end is pulled through the channel during locking and fixed in the housing by means of locking mechanism. The said locking mechanism is represented with detachable during locking turning element at the section with reduced cross section, which follows it. The turning element is provided with pointed threaded end located in the threaded opening of the housing. Threaded opening of the nut is used as threaded opening. The nut is rigidly installed in the end opening along the outer diameter. The end opening is made in housing contacting with smooth blind opening located on the same housing axes. The blind opening crosses through channel perpendicularly. Thus, the rope piece jamming area is formed. The front end of tapered opening is served as the stop for threaded section pointed end when the latter is unscrewed. At the moment of handle breaking off within the area of reduced cross section and when the pointed end is further interacts with the stop, the pointed end will be completely inserted in the rope, while threaded end will be in the nut. The nut is fixed in end opening by means of curling and outer diameter is lowered along edges.

EFFECT: higher resistance to unauthorised unlocking.
