(54) Electric or mechanical lock with manual or automatic leaf opening


(57) An electric or mechanical lock with manual or automatic leaf opening; in the region where an internal spring (10) acts, it is possible to arrange a tool (20) selectively in one of a plurality of seats (13, 14), even when the lock is already installed, interfering with the stroke of the arms (11, 12) of the spring (10) and being adapted to engage one of the arms (11) of the spring (10) in receptacles (A, B) of the latch (4). Once opening enabling has occurred, when the arm (11) is in a first receptacle (A), the spring (10) is not elastically tensioned and applies no torque to the latch (4), this being the setting for manual opening of the leaf; when the arm (11) is in a second receptacle (B), the spring (10) is elastically tensioned and applies a torque to the latch (4) that is suitable to move it away from said post-equipped selvage (2), this being the setting for automatic leaf opening.
