<p>A lock assembly (1) comprising at least one command unit (2), which is driven by a respective key and constituted by a stator (3) and by a rotor (4): the rotor (4) is provided with a recess (5) of a shape and size that are complementary to those of the key. The unit (2) comprises at least one pin for the mutual coupling/decoupling of the stator (3) and the rotor (4), the pin being movable inside a channel that is substantially radial and extends also into the stator (3), and moreover it comprises at least one bit (6), which is operatively associated with the rotor (4) that is designed to mechanically actuate the bolt driven by the lock assembly (1). The lock assembly (1) according to the invention comprises at least one extension element (11), which is interposed between the at least one command unit (2) and the bit (6), and constituted by a main body (12) which has a longitudinal cavity (13) for rotatably accommodating a casing (14) for holding an inner shaft (15). The casing (14) has a first contoured end (16) which is rigidly coupled, directly or indirectly, in the assembled configuration, to the rotor (4) of a unit (2) and a second contoured end (17) which is rigidly coupled, directly or indirectly, to the bit (6). A rotation of the rotor (4) which is imposed by an actuation thereof by means of the respective key produces a rotation of the casing (14) and, therefore, of the bit (6), with respect to the stator (3) and to the main body (12) which are mutually fixed and integral.</p> |
