Abstract
The system consists of cylinder locks and of associated flat keys (4). Mounted in bores (5, 6, 123, 124) in the rotary cylinders (1) are blocking elements (7, 8, 21, 22) which are urged so far outwards by additional longitudinal rings (12, 13, 17, 18) of the key (4) that a housing pin (15) cannot drop into the bores (5, 6, 123, 124) with a blocking effect. In subordinate keys, the lower additional longitudinal ribs (12, 13) are absent, and instead the classifying notch (11) is recessed at the sensing point of the blocking elements (7, 8, 21, 22), so that the plug pin (10) assigned to this notch (11) rises further upwards and with its thickened shank urges the lower blocking elements (7, 8) outwards. The subordinate keys consequently cannot be converted directly into master keys, because they have less material than these. The additional longitudinal ribs (12, 13, 17, 18) are provided with countersinks or interruptions which are sensed by securing pins preceding the blocking elements (7, 8, 21, 22). As a result of these securing pins, the lock cannot be picked from outside by actuating the blocking elements (7, 8, 21, 22).
