- the deactivation means are provided on a support element of said second actuating element interacting with a support element of said first actuating element.
- said support element of said second actuating element is constrained to said command button in a switchable manner between a first configuration in which said deactivation means deactivate said command cylinder and a second configuration in which said deactivation means deactivate said command button.
- said support element of said second actuating element in said first configuration has an unlocked state in which the command button operates, a first locked state in which the command button is locked in the activated position, and a second locked state in which the command button is locked in the deactivated position.
- said command button is translatable and said support element of said second actuating element is constrained to the command button integrally in translation and is rotatable with respect to the command button around an axis parallel to the direction of translation of the command button for switching between said first and said second configuration.

command button 8, thecommand button 8 will have to be pressed so as to have the end of thestem 19 distal from thecommand button 8 project from the relative translation guides 21 and align therecess 36 with thetooth 33, and then thestem 19 manually rotated until engaging therecess 36 in thetooth 33. - In this state, the
lock 1 deactivates thecommand button 8, in that the releasingelement 41 is now presented with theslot 20 in place of thesecond actuating element 14. - However, the pressed
command button 8 remains locked in this position due to the interference of thetooth 33 with therecess 36. - At the same time, in this state, the
lock 1 activates the command cylinder 7, given that thetooth 33, which slides freely in therecess 36, enables thefirst actuating element 12 to move until it comes into contact with the releasingelement 41 for actuating it. - Thus conceived, the lock for application that is highly flexible in terms of use is susceptible to numerous modifications and variants, all of which falling within the scope of the invention as defined by the appended claims.
- Moreover, all details may be replaced with other technically equivalent elements. The materials used, as well as the dimensions, may in practice be of any type, according to needs and the state of the art.

- The lock (1) to be applied to a wall of a door leaf according to any one of claims 2 to 4, characterised in that said command button (8) is translatable and said support element (16) of said second actuating element (14) is constrained to the command button (8) integrally in translation and rotatable with respect to the command button (8) around an axis parallel to the direction of translation of the command button (8) for switching between said first and said second configuration.
- The lock (1) to be applied to a wall of a door leaf according to the previous claim, characterised in that said support element (16) of said second actuating element (14) is formed of a stem (19) which extends behind the command button (8).
- The lock (1) to be applied to a wall of a door leaf according to the previous claim, characterised in that said second actuating element (14) is provided at the end of the stem (19) distal from the command button (8).
- The lock (1) to be applied to a wall of a door leaf according to any one of claim 6 and 7, characterised in that said deactivating means (15) comprise for deactivation of the command button (8) a slot (20) of the stem (19) at the end of the stem (19) distal from the command button (8).
- The lock (1) to be applied to a wall of a door leaf according to any one of claims 6 to 8, characterised in that said deactivating means (15) comprise for deactivation of the command cylinder (7) a lateral arrest surface (32) of the stem (19) for the support element (17) of the first actuating element (12).
- The lock (1) to be applied to a wall of a door leaf according to any one of claims 2 to 9, characterised in that said support element (17) of said first actuating element (12) is formed of a flat plate (22) parallel to a flat rear wall (3) of said box-like body (2) applicable to said wall of said door leaf.
- The lock (1) to be applied to a wall of a door leaf according to the previous claim, characterised in that said plate (22) is translatable in a direction of translation parallel to said flat rear wall (3) of said box-like body (2).
- The lock (1) to be applied to a wall of a door leaf according to any one of claims 10 and 11, characterised in that said plate (22) has selective engaging teeth (35, 36) in a first lateral recess (36) of the stem (19) to retain it in said first locked state or in a second lateral recess (37) of the stem (19) axially offset from the first recess (36) to retain it in said second locked state.
- The lock (1) to be applied to a wall of a door leaf according to any one of claims 10 to 12, characterised in that said cover (6) is formed of a front element (24) and a rear element (38) which delimit a closed compartment in which said plate (22) is positioned.
- The lock (1) to be applied to a wall of a door leaf according to any one of claims 10 to 13, characterised in that it comprises an eccentric screw (26) of adjustment of the angular position of said plate (22) for selection of the hand of the lock.
