<p>The invention relates to a lock with a pivoting bolt rotating about a fixed point, especially as an additional lock (4) on espagnolette locks (1), in which lock the movement of the pivoting bolt (27) is achieved as a result of the engagement of a taken-up driver (46) into a recess (37) which forms a plurality of interconnected portions arranged at an angle to one another, for the purpose of driving the pivoting bolt (27) on the one hand, and a non-return position of the latter, on the other hand, and, for the purpose of achieving an optimum locking mode, proposes that the recess (37) provided in the pivoting bolt (27) be designed as a window (F) with a niche (42) directed radially towards the fixed point from one window corner, and that the window ledges (39, 40) adjoining the niche sidewalls (43, 44) be designed as blocking portions, in front of which the driver (46) is located in the end positions of its movement. <IMAGE></p> |
