Abstract (en)
A coding mechanism for a cylinder lock with a rotatable key consists of a guiding element (13) for aligning the shank (14) of the rotatable key (12) inside the cylinder lock and of the rotatable key (12) itself, wherein the guiding element (13) comprises two mutually parallel and spaced apart guide rails (15), which have their ends interconnected by an abutment bridge (16) and which are provided with guiding surfaces (18) extending along their entire lengths, the shank (14) of the rotatable key (12) being provided with usual coding projections (21) adapted for interaction with usual catchers arranged inside the respective cylinder lock and having its entire cross-section continuously increasing from its intermediate portion towards at least one of its longitudinal edges (36, 37), at least one of the two pairs of the functional surfaces (38, 39 and 40, 41) of said shank having an open V-shape and the intermediate portion of the cross-section of the same being provided with a pair of corresponding longitudinal notches (22, 23). The longitudinal notches (22, 23) have flat bottom portions (24, 25), the guiding surface (18) of at least one guide rail (15) and the corresponding flat bottom portion (24, 25) of the respective longitudinal notch (22, 23) formed in the shank (14) of the rotatable key (12) having their shapes adapted for generating a locking code of the cylinder lock.
