Abstract

Die Erfindung betrifft ein Schloss- Schlüssel- System, dessen Flachschlüssel (1) mit einem einen Schlüsselrücken (2) und eine Schlüsselbrust (3) aufweisenden Schlüsselschaft versehen ist, an den sich eine Schlüsselreide anschließt, wobei die Schlüsselbrust mit eine mechanische Codierung darstellenden Kerben versehen ist und die Seitenflächen des Schlüsselschaftes eine längs des Schlüsselschaftes verlaufende Profilierung aufweisen, die von einer komplementären Profilierung im Zylinderkern des Schließzylinders erfassbar ist.The invention relates to a lock and key system, the flat key (1) is provided with a key shank having a key back (2) and a key-chest (3), to which a key crop connects, the key-chest provided with a mechanical coding notches is and the side surfaces of the key shank have a along the key shank extending profiling, which is detectable by a complementary profiling in the cylinder core of the lock cylinder.

Dabei ist wenigstens eine der seitlichen Profilierungen als Schwalbenschwanznut (4) ausgebildet mit einer oberen, dem Schlüsselrücken (2) zugewandten und einer unteren, der Schlüsselbrust (3) zugewandten Hinterschneidung (5,6), wobei der Winkel (α) der schlüsselrückenseitigen oberen Hinterschneidung (5) in seiner Verlängerung (13) in Richtung Schlüsselschaft - Mittelebene (7) so gewählt ist, dass er in der Verlängerung (13) die innere, obere schlüsselrückenseitige Ecke (8) eines auf der der Schwalbenschwanznut gegenüber liegenden Schäftseite vorgesehenen ersten parazentrischen Merkmals (9) trifft, wahrend der Winkel (β) der unteren, schlüsselbrustseitigen, Hinterschneidung (6) in seiner Verlängerung (14) die obere, schlüsselrückenseitige Ecke (10) eines auf der Schwalbenschwanzseite vorgesehenen parazentrischen Merkmals (11) trifft.

In this case, at least one of the lateral profiles as a dovetail groove (4) is formed with an upper, the spine (2) facing and a lower, the key-chest (3) facing the undercut (5,6), wherein the angle (α) of the spine back upper undercut (5) in its extension (13) in the direction of the key shank - median plane (7) is selected such that in the extension (13) the inner, upper spine side corner (8) of a first paracentric feature provided on the side opposite the dovetail groove (9) meets, while the angle (β) of the lower, keyhole-side, undercut (6) in its extension (14) hits the upper, spine-side corner (10) of a dovetail-side paracentric feature (11).
