<p>A lock with rotary latch (8) provided with a slot adapted to engage a bracket (34) fixed to the abutment jamb of a door, the lock comprising a box-like body (1), which can be fixed at the abutment edge of a door and is provided with a portion (3) that protrudes from the edge, in which the latch (8) is mounted so that it can rotate, the slot (14) being shaped so as to produce, when the door closes, the engagement of the bracket (34) in the slot, and therefore the rotation of the latch (8) until it reaches the position for engaging the bracket, a locking device (37) being further provided for locking the latch (8) in two stable positions that correspond to the closure and opening positions of the door, respectively, the latch accommodating at least one element (18, 19) controlled by a member (25, 26) arranged in the slot, the element (18, 19) being movable between a position for blocking the rotation of the latch (8) when the latch is disengaged from the bracket (34) and a position for enabling the rotation of the latch when the member (26) detects the presence of the bracket (34) in the slot (14). <IMAGE></p> |
