LOCKING MECHANISM FOR PASSIVE DOOR LEAF (VERSIONS) Russian patent published in 2013 - IPC E05C9/16 

FIELD: construction.

SUBSTANCE: invention relates to the field of hardware and touches upon a locking mechanism for a passive door leaf, comprising a body, a driving plate installed in the body, capable of limited rotation and interaction with at least one bar by means of a hinged joint at least via one eye. Bars are mounted in the body as capable of displacement along their axis. Limitation of rotation of the driving plate is carried out through geometric closure of the plate and the eye. Fixation of the driving plate in extreme positions is carried out by a compression spring. At the same time the compression spring goes over the extreme compressed position "dead point".

EFFECT: increased reliability of locking with simultaneous simplification of leaf locking control.
