<p>A universal lock (1) for swing-doors, of the type comprising a box- like body (2) for containing a movement cylinder (3) that is associated with a respective actuation key, a rotating bush (4) associated with a handle, suitable lever systems (5) for the translational motion of at least one latch (5) and of at least one bolt (7), functionally associated with the handle and the cylinder (3), and a pivot (9) that protrudes, biassed by elastic transmission means. The at least one bolt (7) is locked in the extracted configuration when the pivot (9) protrudes, and is free, for a retraction which is forced by an external force, when the pivot (9) is pressed to retract, against the bias of the elastic transmission means, by an external force. The lock (1) comprises means for the mechanical deactivation of the pivot (9).</p> |
