Lock cylinder to be actuated by keys of different ranking

摘要

The invention relates to a lock cylinder (1) which is to be actuated by a key of different ranking and the cylinder plug (4) of which has a keyway (6) for inserting and withdrawing the keys in a specific rotary-angle position, and in which tumblers (9, 16) are arranged and at least one of the tumblers (9, 16) to be put in position by the key to be inserted is assigned an intermediate plate (14) which, when one key (7) is used, extends in the lock-cylinder housing (2) and, when the other key is used, travels over into the cylinder plug (4). For the purpose of an improvement in use, the invention proposes a second key withdrawal position (A) for the higher-ranking key (7). <IMAGE>
