ABSTRACT:
The mechanism of the invention can be mounted on and in contact with a frame. A spindle (2) is disposed within a shallow strip-like housing (1) parallel to an edge of a glazed sash of a window or door and a slider (3) displaceable on rotation of the spindle (2) is mounted on the spindle in order to drive a latching and/or deployment device for the glazed sash. The spindle can be adjusted by means of a knob-like handle (4) which is drivingly connected with the spindle (2) via gears (5, 6). A safety coupling (15 to 23) which limits the maximum achievable positioning force is arranged inside the handle (4).
