Abstract
A hand-actuated control device with an actuating element which extends largely parallel to the axial plane and is fastened to the control lever, the two control signal generators can be actuated individually or jointly in order to generate a control signal. Between two first control signal generators is arranged a further control signal generator. A control lever can be turned together with an actuating element about the lever axis from a first turning position, in which the first control signal generators can be actuated by the actuating element, into a second turning position and vice versa. The actuating element is provided with a recess in such a way that the further control signal generator can be actuated only in the second turning position.
Claims8
A hand-actuated control device, with a control lever (21), which is swivelable from a neutral position to all sides about a swivel point (23), about axes lying essentially in an axial plane and intersecting at the swivel point (23), with at least two control signal generators (11), which are arranged spaced apart from one another by a given angle in relation to a lever axis (12) which is perpendicular to the axial plane and passes through the swivel point (23), and with an actuating element (30) which extends largely parallel to the axial plane and with which the two control signal generators (11) are actuatable individually or jointly when the control lever (21) is swiveled out of the neutral position, wherein between the two first control signal generators (11) there is arranged a further control signal generator (11), the control lever (21) is turnable together with the actuating element (30) about the lever axis (12) from a first turning position, in which the first control signal generators (11) are actuatable by the actuating element (30), into a second turning position and vice versa, and that the actuating element (30) is provided with a recess (32) such that the further control signal generator (11) is actuatable only in the second turning position.
