Abstract (en)

[origin: EP3578742A1] A cylinder lock (10) intended to be operated by a key has a rotor (12) mounted rotatably in a housing (14). A plurality of spring-loaded tumblers (18) are arranged moveably in the rotor (12) and in the housing (14) along a locking direction (L) between a locked position in which they prevent a rotation of the rotor (12) and an unlocked position in which they allow the rotation of the rotor (12). Each tumbler (18) is pretensioned towards its locked position by a spring element (22) arranged alongside the tumbler (18) with regard to the locking direction (L), each spring element (22) being arranged in a receptacle (24) formed in the rotor (12). A sidebar (34) is provided on the rotor (12), the sidebar (34) being arranged for motion between a locked position in which it prevents the rotation of the rotor (12) and an unlocked position in which it allows the rotation of the rotor (12), wherein the sidebar (34) is arranged along the locking direction (L) of the tumblers (18) beyond a radially inner end (30) of all receptacles (24) of the spring elements (22).
