Abstract: A cylinder lock and an associated key, the lock including a fixed body and a plug which is accommodated within a respective cavity of the body and can rotate with respect to the body. The plug includes a substantially longitudinal compartment for the functional accommodation of a key which includes a grip portion from which an elongated body extends and which is provided with coding grooves and protrusions on its outer surface. Between the plug and the body are respective accommodation channels for translating coding elements, which open onto the substantially longitudinal compartment. The plug includes at least one auxiliary duct which faces the substantially longitudinal compartment and extends at least partially in the body for the sliding accommodation of at least one coding unit that includes at least one pin and at least one conical portion.

Abstract: A cylinder lock and an associated key, the lock comprising a fixed body and a plug, which is accommodated within a respective cavity or the body and can rotate with respect to the body. The plug comprises a substantially longitudinal compartment for the functional accommodation of a key which comprises a grip portion from which an elongated body extends which is provided with coding grooves and protrusions on its outer surface; between the plug and the body there are respective accommodation channels for translating coding elements, which open onto the substantially longitudinal compartment; the plug comprises at least one auxiliary duct, which faces the substantially longitudinal compartment and extends at least partially in the body, for the sliding accommodation of at least one coding unit that is constituted by at least one pin and at least one conical portion.

Abstract: A lock with associated key, of the type comprising a stator provided with a substantially cylindrical longitudinal cavity for accommodating a rotor with a longitudinal recess for the insertion of a coded key. The rotor and the stator comprise a plurality of channels which accommodate respective pins, complementary pins and optional elastic elements. At least one of the pins has at least one substantially lateral protruding tab, whose upper edge is suitably contoured. The key has a cross-section that is complementary to the cross-section of the longitudinal recess when the pins, at the regions aligned with the tab, are in a configuration for disengaging the stator and the rotor, accommodating with contact the end of the pins in respective coding recesses and the contoured rim of the corresponding tab on complementarily shaped portions.

Abstract: A cylinder with associated key, comprising a stator provided with a longitudinal cavity for accommodating a rotor with a longitudinal recess for the insertion of a coded key. The rotor and the stator comprise channels for accommodating respective pins, complementary pins and any elastic elements. The rotor comprises at least one second passage, the passage and the cavity accommodating at least one respective movable peg, whose head rests against the blade edge of the key when the key is inserted in the recess. The key is provided with suitable contoured regions on its blade edge at the surfaces that face said pegs when inserted in the recess. Each peg has its base inside the respective cavity so as to block the rotation of the rotor with respect to the stator when a key lacking the corresponding contoured regions is inserted.

Abstract: A cylinder lock and key comprising primary pins which are mutually opposite with respect to a longitudinal slot provided in the rotor of the cylinder for insertion of the key; the primary pins are associated with respective movable complementary pins accommodated within respective passages of the rotor and the stator, provided at the surface of discontinuity formed between the stator and the rotor of the cylinder. The key has a seat for accommodating a respective orientable lever, that actuates the primary pins aligned with it: the lever has a thickness variable, even locally and discontinuously, according to a coded pattern, depending on geometry and arrangement of the primary pins, forming a particular configuration of contact of the heads of the primary pins against the surface of the lever at which the complementary pins are completely accommodated within only one of the passages.
