    • A break-in resistant lock cylinder (1) for a cylinder lock, comprising a stator (3) which is provided with a substantially cylindrical accommodation (4) for a rotor (5). The rotor (5) and the stator (3) are affected by at least one channel (6) for at least one respective pin (7), which is slideably moveable inside it. The arrangement, for locking, of the at least one pin (7) partly in the rotor (5) and partly in the stator (3) results in the immobilization of the rotor (5); the arrangement, for opening, with the alignment of an end edge (8) of the at least one pin (7) with the interface surface between stator (3) and rotor (5), which is obtained by way of the insertion of an adapted key (2) with a contoured profile into an opening (9) of the rotor (5) facing onto the at least one channel (6), results in the free rotation of the rotor (5) with respect to the stator (3). The at least one pin (7) comprises an ogive (10) which is provided with a contoured cavity (11) and a peg (12) which is provided with two mutually opposite protruding appendages (13, 14) and with a central rim (15) acting as an abutment shoulder. The at least one channel (6) of the rotor (5) comprises a first section with a substantially larger diameter than the diameter of the central rim (15) and a second section with a substantially smaller diameter than the diameter of the central rim (15) and larger than the diameter of a first protruding appendage (13). The front of the first protruding appendage (13), upon the insertion of the key (2) into the opening (9) of the rotor (5), is accommodated in a respective profiled groove (18), which has different depths at different longitudinal sections of the key (2), with consequent substantially complete insertion of the second protruding appendage (14) into the cavity (11) of the ogive (10) according to the open arrangement.

    • A lock (1) for leaf doors which comprises a box-like body (2) for containing a movement cylinder (3) associated with a respective actuation key, a rotating bushing (4) associated with a handle, adapted lever mechanisms (5) for the translation of at least one spring latch (6) and of at least one sliding latch (7), which are functionally associated with the handle and with the cylinder (3), and a tab (9) protruding from the sliding latch (7). The at least one sliding latch (7) is locked in the extracted configuration when the tab (9) is protruding, and it is free to retract if subjected to an external force, when the tab (9) is retracted inside the sliding latch (7) following a respective external action. The sliding latch (7) comprises an internal cavity for the slideable accommodation of a lever (10) that is constituted, at a first end thereof, by the tab (9), and, at a second end thereof, by a tooth (1 1); the tooth (1 1) is facing toward an arm (12) of a cam (13) that is pivoted to the box-like body (2). A second arm (14) of the cam (13) is resting against a protrusion (15) of an element (16) for the movement of the sliding latch (7). The movement element (16) comprises a projection (18) that can slide within a groove (19) of the sliding latch (7). The groove (19) is provided with an inclined portion (20) and with an offset recess (21) for the accommodation of the projection (18) in the locked configuration of the sliding latch (7). The retraction of the tab (9) causes the forcing of the tooth (1 1) on the arm (12), with consequent rotation of the cam (13) and lifting of the arm (14): this causes the translation of the movement element (16) by means of the protrusion (15). Such translation causes the egress of the projection (18) from the offset recess (20) of the groove (19) with consequent free retraction of the sliding latch (7), and of the spring latch (6) which is mechanically coupled thereto, following an external force applied thereto.
