In the case of an actuating device, in particular for a rod control, with a foot lever (2) to be actuated from the sitting position, said foot lever is combined with a control lever arm (11), assigned to the base of the former, to give an angle lever and is articulated at the pivot point at the free end of a frame (5) which can be used as a single-arm lever, movable in the same pivot direction, and can be fixed in any adjustable angle position. Along with a rocker (13) which can move about the pivot point of the frame, the control lever arm (11) forms, via a coupling rod (12), a four-bar mechanism with the rocker as a two-armed lever, on the free lever arm (13.1) of which a control rod (1) is articulated. For the purpose of extending with a (second) foot lever (18) of a different actuating device, said second foot lever is articulated at the tip of the first foot lever (2) at such an angle that, for moving the second foot lever (18), the tip of the first foot lever can be used as foot-supporting and foot-pivoting point (17), at the same time the second foot lever (18) being in engagement via its base with a control lever arm (19). <IMAGE> |
