  • the door actuating device according to the invention in particular the adjusting nut does not have to be secured against rotation.
  • the adjusting element which is guided by the screw plug, presses against the adjusting nut, wherein the adjusting nut is guided in the direction of the spring, which allows an adjustment of the spring.
  • the door operating device according to the invention can also be used without setting a special design, for example as an adjusting nut designed as a polygon for adjusting springs whose pressing force would not be sufficient in itself to prevent co-rotation of the adjusting nut in the door operating device.
  • the adjusting element is guided in a bore of the cylinder, wherein the bore has, at least in sections, an internal thread which can be brought into positive engagement with a corresponding thread configured at least in sections on the adjusting element.
  • the thread namely by its pitch can be adjusted in a preferred manner, the section-wise propulsion of the adjustment of thread to thread.
  • the adjusting nut is preferably below the spring support as a pin formed, which at least partially surrounds the cylinder of the locking screw and the adjustment introduced by the screw plug.
  • the adjusting element is preferably located at one of its ends on a bottom formed by the pin within the adjusting nut on this floor. Since the pin extends in an advantageous manner to the locking screw out in a spring support, wherein with advance of the adjusting element, which comes to rest on the bottom of the pin, the spring support is moved, thereby also the spring is compressed.
  • the pin extends at least partially into the spring, so that the spring surrounds the pin.
  • the spring adjustment of the present invention has a particularly small design, since both the adjusting element with its pin and the adjusting element, at least in sections, are arranged within the spring.
  • closure screw on the cylinder, which extends with the adjusting element into the spring, and on which the adjusting element is guided linearly, is designed as a housing cover for one end of the housing of the door operating part ,
  • the closure screw preferably has an external thread which is screwed into an internal thread of the housing of the door operating part.
  • the closure screw has at least one sealing ring in its section designed as a housing cover, which rests between the locking screw and the inner wall of the housing.
  • the housing cover which is formed by the screw plug, is preferably in its circumference, ie adapted in its the cylinder overhanging portions of the circumference of the housing of the door operating part.
  • the insertion depth, and in particular the depth of engagement of the adjusting element into the screw plug is suitable for checking the adjusting travel of the adjusting nut.
  • the adjusting element is guided centrally through the screw plug. More precisely, the adjusting element is guided in a bore which runs through the locking screw. Accordingly, the adjustment can be operated on the outside of the housing cover formed by the screw plug.
  • the adjusting element is a screw whose thread is brought into positive engagement with the internal thread of the cylinder of the screw plug.
  • the spring is preferably a compression spring.
  • compression of the compression spring namely by the adjusting element, which is pressed with the screw or the adjusting element with its pin in the spring and thereby entrains the spring bearing, the compression spring can be brought to the desired bias.
  • the Preload the compression spring is adjusted so that the closing of a door leaf when opening the door to be stored energy, sufficient to close the door again automatically.
  • the spring may also be a tension spring.
