Abstract (en)
[origin: US5964112A] A locking cylinder (1) with a cylindrical housing (2) of which the core bore (7) receives a cylindrical core (8) having a key channel (9) with core pins provided in the cylindrical core and housing pins displaceably guided in housing pin bores, the housing pins being resiliently biased by springs in the direction of the core pins, and with at least one additional, core-adjacent tumbler element (15) adjacent the wide-side profile of the key, the element (15) being displaceable in a cavity (H) crossing the rotational interface of the cylindrical core, the tumbler element being spring biased in the outward direction of the core and having a control projection (22, 51) projecting sidewards into the key channel (9, 43). In order to provide greater security, a locking recess (13', 48) is located in crossing or opposing relation to the housing pin bores, for receiving the additional tumbler element (15, 49) so as to block rotation, in which a housing-adjacent tumbler pin (14) biased in the inward direction of the core is able to project into the core cavity (13) when the tumbler pin (15) is withdrawn across the rotational interface (F), and in which the spring force of the spring (17) loading the additional tumbler element (15) is larger than that of the spring (18) which loads the housing-adjacent tumbler element (14).
