Then there will be an adjustment the drive link compared to the output member of the rotary drive prevented. It is particularly advantageous if the output member of the rotary drive is a rotary part is with a polygonal bore and that through this bore a cross member is used closing, the end areas with parallel bars of the pivoting functional part or the drive links of the upright fitting are connected. There is then a coupling between the parallel drive arms of the upright fitting.
  • the rotary drive is extremely accessible, it is provided that it is in the area one long side of the support element is mounted. It is then advantageous if the Querholm with its end facing away from the rotary drive into or into a profile piece is plugged in, which on the drive link facing the rotary drive Side is arranged, which is however facing away from the rotary drive. It will thereby achieving an assembly-friendly design.
  • the end positions of the functional element to be pivoted are in the known actuators limited by two limit switches, which within the Rotary actuator are mounted. These limit switches are placed on a bar. A such a design is also fundamental in the actuating device in question possible.
  • the end positions of the functional element to be pivoted by at least one stop is limited, either in the housing of the rotary drive, on the fitting or on Support element is arranged.
