Abstract

Rotationssymmetrischer Kraftangriff (12, 112) mit bei axialer Betrachtung sternförmiger Außen- oder Innen-Kontur, vorzugsweise für Verbindungselemente, wobei die einzelnen Arme (18, 118) des Sterns als Spitzbögen ausgebildet sind, deren äußere Spitzen auf einem gemeinsamen Außenkreis (22, 122) liegen, wobei ein zugehöriges Gegenstück, insbesondere Bit, Nuss oder Schraubenkopf, zur Kontur des Kraftangriffs (12,112) eine dergestalt angepasste Gegenkontur aufweist, dass die Radien (20, 120) der Flanken des Kraftangriffs (12, 112) und das Gegenstück derart aufeinander zur Anlage kommen, dass eine flächenförmige Pressfläche entsteht, für den Fall, dass insbesondere Kontur und Gegenkontur der erfindungsgemäßen Form des Kraftangriffes entsprechen, die Anpassung von Kontur und Gegenkontur dadurch bewirkt wird, dass die Radien (20) bei der Außenkontur (12) 4 % bis 12 %, besser 6 % bis 10 %, besser etwa 8% bis 10 % kleiner gewählt sind als bei der zugehörigen Innenkontur (112), während bei Kontur und Gegenkontur der Innenkreis (14; 114), auf dem die Mittelpunkte der Radien (20; 120) um die Rotationsachse (10; 110) des Kraftangriffs (12; 112) herum angeordnet sind, nahezu den gleichen Durchmesser aufweist, insbesondere bei der Außenkontur um 4% bis 6%, insbesondere um 5 % größer ist gegenüber dem Durchmesser bei der Innenkontur.
