Abstract (en)
[origin: EP0861957A2] The key shaft has a basic profile with T-shaped cross-section. The T-bar forms a guide arm with guide surfaces. The vertical T stem running along the lengthwise centre plane forms the breast at the end side, and possesses broad side surfaces for forming profiled ridges which have curved cross-sectional outlines. The opposite-facing broad side surfaces (5,6) each form at least one longitudinal groove (7,8) with a groove-base protruding beyond the lengthwise centre plane (M-M). The sides of the groove and the breast surface (4) run in a circle or ellipse at a tangent from the broad side surfaces.
