Patent ID: 7690232

Claim:
A lock device with a lock cylinder ( 10 ), which comprises a stationary cylinder housing ( 11 ) and a cylinder core ( 12 ) rotatably supported therein, with a key ( 20 . 1 , 20 . 2 ), which has an edge profile ( 25 . 1 , 25 . 2 ) and can be inserted into an axial keyway ( 15 ) of the cylinder core ( 12 ), with platelet-shaped tumblers ( 13 , 14 . 1 to 14 . 3 ), which already engage in a locking channel ( 18 ) of the cylinder housing ( 11 ) via a spring force ( 41 - 43 ) when the key ( 20 . 1 , 20 . 2 ) is not inserted, and which are movable transversely to the keyway ( 15 ) when the key ( 20 . 1 , 20 . 2 ) is inserted, and sorted against the cross section of the cylinder core ( 12 ) by the spring force ( 41 - 43 ), with at least one longitudinally profiled shoulder ( 28 ) on a flat side ( 38 ; 39 ) of the edge profile ( 25 . 1 ) of the key ( 20 . 1 , 20 . 2 ), which shoulder ( 28 ) extends in the longitudinal direction and produces different scanning points of a standard coding ( 26 , 53 ) on the key ( 20 . 1 ; 20 . 2 ) by virtue of the course of its profile, and with a cooperating shoulder ( 30 ) on at least some tumblers ( 13 ), which then act as standard tumblers ( 13 ), where, when the key ( 20 . 1 ; 20 . 2 ) is inserted, the cooperating shoulders ( 30 ) of all the standard tumblers ( 13 ) are supported on the longitudinally profiled shoulder ( 28 ) of the key and produce a standard counter coding ( 16 ) that is complementary to the standard coding ( 26 , 53 ) of the key ( 20 . 1 ; 20 . 2 ), wherein, in addition to the standard coding ( 26 ), the key ( 20 . 1 ; 20 . 2 ) has beveled codings ( 27 . 1 to 27 . 4 ) in corner regions of its edge profile ( 25 . 1 , 25 . 2 ), because bevel cuts ( 29 . 1 to 29 . 4 ) of variable depth ( 36 . 1 to 36 . 3 ) are cut into the corner regions of its edge profile ( 25 . 1 , 25 . 2 ), thus forming profiled corner strips ( 21 to 24 ), which extend in the longitudinal direction of the key and carry the beveled codings ( 27 . 1 to 27 . 4 ); where an oblique cooperating scanning point ( 47 . 1 to 47 . 4 ) in one of the tumblers ( 14 . 1 to 14 . 3 ) is associated with at least one scan point in the beveled codings ( 27 . 1 to 27 . 4 ) of the key 20 . 1 ; 20 . 2 ), which tumbler then interacts as a beveled tumbler ( 14 . 1 to 14 . 3 ) with the inserted key ( 20 . 1 ; 20 . 2 ); and where oblique cooperating scanning points ( 47 . 1 to 47 . 4 ) on a family of beveled tumblers ( 14 . 1 to 14 . 3 ), which are located together in the cylinder core ( 12 ), produce a beveled countercoding in the lock device ( 10 ).
