MECHANISM FOR SECURING THE HANDLE OF A DOOR OR WINDOW

摘要

The device has a locking spring unit arranged in a base part or a knob plate (1). A locking unit designed as a headless screw interacts with the locking spring unit so that the locking spring unit is deformed, when the locking unit is displaced transverse to an axis of a handle or knob (9). Locking lugs (8) arranged on the periphery of the locking spring unit disengage from or engage with recesses (10) at or in a part of the handle or knob encircling the locking spring unit and the base part or knob plate.
