Abstract

Ein Schließzylinder (1) ist durch einen Schlüssel (15) sperrbar, der eine mechanische Codespur mit einer Höhenprofilierung in mehreren Höhenniveaus (27, 28, 29) aufweist, die schloßseitig durch eine Leseeinrichting identifizierbar ist, welche einen analogen Geber, beispielsweise einen durch Druck veränderbaren Widerstand, insbesondere Gummiwiderstand (19), in einem Meßkreis (20) umfaßt. Beim Einschieben des Schlüssels (15) in einen Schlüsselkanal (14) wird die Codespur durch einen Taststift (13) abgetastet und die codeabhängige Meßgröße, z. B. die druckabhängig variablen Widerstandswerte werden nacheinander erfaßt. Sie ergeben einen Code, der mit dem Code eines Code-speichers (22) verglichen wird. Bei Codeübereinstimmung liegt ein Entriegelungssignal für eine elektromechanische Verriegelung (26) an. Der Schließzylinder (1) kann ferner die üblichen Stiftzuhaltungen (4, 5, 6, 7, 8) zusätzlich aufweisen. A lock cylinder (1) can be locked by a key (15), which has a mechanical code track with a height profile in several height levels (27, 28, 29), which can be identified on the lock side by a reading device, which is an analog transmitter, for example one by pressure changeable resistance, in particular rubber resistance (19), in a measuring circuit (20). When the key (15) is inserted into a key channel (14), the code track is scanned by a stylus (13) and the code-dependent measured variable, e.g. B. the pressure-dependent variable resistance values are recorded one after the other. They result in a code which is compared with the code of a code memory (22). If the code matches, there is an unlocking signal for an electromechanical locking (26). The locking cylinder (1) can also have the usual pin tumblers (4, 5, 6, 7, 8).
