Abstract

Zur Vereinfachung des konstruktiven Aufbaus ist ein mit einem in der Verriegelungsstellung unter Federkraft gesicherter Sperrriegel (6) eines Kupplungshakens (2) mit einem Langloch (13) versehen, über welches in Verbindung mit einem fest angeordneten, entlang des Langlochs (13) gleitfähigen Lagerbolzen (12) eine kulissenartige Führung des Sperrriegels (6) zwischen der Verriegelungs- und der Entriegelungsstellung gebildet ist. An dem einen, die Verriegelungsstellung definierenden Ende des Langlochs (13) ist eine, zur Aufnahme des Lagerbolzens (12) bestimmte, in Wirkungsrichtung einer Zugfeder (16) offene Rastausnehmung (14) vorgesehen, wodurch eine sichere Positionierung des Lagerbolzens in der Verriegelungsstellung gegeben ist. Der gleiche Zweck wird auch dadurch unterstützt, dass die Längsseiten des Langlochs als Kreisbogenelemente ausgestaltet sind, die zur Oberseite (8) des Hakenkörpers hin, somit in Gegenrichtung zu der Wirkungsrichtung der Zugfeder (16) konkav gekrümmt sind.
