Abstract

An actuating handle arrangement for the actuation of fittings of a window casement or a door leaf includes an actuating handle which is mounted for turning about a turning axis on a housing which is secured to a window casement or door leaf frame. The actuating handle operates a pusher bar fitting which is coupled with an entraining member of a slide which is mounted in the housing for displacement in the longitudinal direction. The slide is provided with a guiding groove, in which there engages an entraining pin of an eccentric which is connected with the actuating handle. In the end positions of the actuating handle which correspond to the closing and the tilting position of the window casement, the line connecting the intersection point of the turning axis and the intersection point of a central axis of the entraining point with an imaginary plane along which the slide moves extends at right angles to the central longitudinal axis of the guiding groove.
