<p>A rekeyable cylinder (1) comprising a stator (2) that is provided with a substantially cylindrical accommodation (3) for a rotor (4); the rotor (4) and the stator (2) are affected by channels (5) for at least one respective pin, which is slideably movable therein in contrast with respective elastic means; the simultaneous arrangement of the pins partially in the rotor (4) and partially in the stator (2) determines the locking of the rotor (4), while the alignment of an end tip of the pins with the interface surface between stator (2) and rotor (4), which is obtained by way of the insertion of an adapted key (7) with a contoured profile in an opening (6) of the rotor (4) facing the channels (5), determines the free rotation of the rotor (4) with respect to the stator (2); at least one of the pins is constituted by a pair of substantially complementary half-members (9, 11) that are provided, along at least one respective mutual coupling surface, with at least one respective contoured portion (10), the first half-member (9), and with at least one respective complementary contoured portion (12), the second half-member (11); the first half-member (9) is capable of performing a translational movement with respect to the stator (2) and the rotor (4); the second half-member (11) is capable of performing a translational and rotational movement, according to a predefined angular path, with respect to the stator (2) and the rotor (4); the second half-member (11) comprises means of abutment for a specific tool (13) that engages therewith through a rotoric auxiliary half-conduit (14a) and a statoric auxiliary half-conduit (14b) which are mutually aligned, following a rotation of the key (7) inserted in the opening (6), the half-conduits (14a, 14b) facing the abutment means.</p> |
