ABSTRACT:
An operating device for doors, windows, etc. comprises a rosette (20) for holding a rotating handle (10) whose head (12) contains a lock cylinder (18) with an axially displaceable locking bolt (44) that is axially spring-loaded and automatically assumes an engaging position at a defined angle of rotation of the handle (10) by sliding over a stepped locking sleeve (30) of the rosette (20). The lock cylinder (18) has a core (40) with a radial opening (50) in a non-rotating wall (58) for controlled movement of a spindle (48) that radially extends from the locking bolt (44) which engages the locking sleeve in defined angular positions of the handle (10). The opening (50) extends over a peripheral angle of e.g. 180° to 220°, and is a contoured window having a lower flat segment (52), a depression (54) and a steeper segment (flank56). On top, two straight edge sections (62, 66) run out at a vertical intermediate edge (58) above the depression (54), with lateral edges of the opening (50) forming stops for the spindle (48). If the key S is in the cylinder (18), pivoting the handle (10) from a horizontal position into an upward position (12 o'clock) requires two-hand operation. As the handle (10) is turned down into a transverse position (3 o'clock or 9 o'clock), the locking bolt (44) engages behind a tangential stop (68) under spring load, whether or not the key (S) is in the lock cylinder (18).
