The invention relates to an actuating mechanism (1), in particular a lock, for actuating an espagnolette (2) of an espagnolette fitting (3) for liftable and movable window or door leaves (4), comprising a housing (6) for receiving a coupling or drive element (7) which can be connected to the espagnolette (2) and which is coupled to an actuating slider or lever (8) that is rotatably connected to a crank piece (9) mounted in the housing (6). The espagnolette (2) can be moved downwards by a specified stroke in order to lower the leaf (4) by rotating an actuating element (11), which engages into a polygonal opening (10) of the crank piece (9), and transmits the movement to the carriage arrangement (15), which is secured on the lower horizontal leaf beam (3) within a fitting groove (14), via a corner deflection element (12). The polygonal opening (10) has one or more recesses (16) in an axial direction, said recesses intersecting the sides of the polygonal opening (10) so as to form an opening (17). A peg (18) engages into the recess (16), said peg protruding into the polygonal opening (10) so as to extend over the opening (17) when engaging into the recess (16). |
