DETAILED DESCRIPTION OF THE DRAWINGS

[0040] A revolving door arrangement 100 with a door actuator arrangement 1 is described below in detail on the basis of FIGS. 1 to 6. The door actuator arrangement 1 is mounted in the exemplary embodiments in accordance with the method according to the disclosure.

[0041] FIG. 1 shows for all exemplary embodiments the revolving door arrangement 100 with a frame 101 and a door leaf 102 received in the frame 101 in a rotationally movable manner. Furthermore, the revolving door arrangement 100 comprises the door actuator arrangement 1.

[0042] The door actuator arrangement 1 comprises a door actuator 2, designed here as a door drive. The door actuator 2 is attached on the door leaf 102. Furthermore, the door actuator arrangement 1 has a linkage 3. In the example shown, the linkage 3 comprises a lever 4, which is connected to a sliding piece 6 in a rotationally movable manner. The sliding piece 6 is guided in a linearly movable manner in a slide rail 5. The slide rail 5 is attached to the frame 101.

[0043] Moreover, the lever 4 with a linkage head 7 is connected in a rotationally fixed manner to an output shaft 9 of the door actuator 2. The output shaft 9 of the door actuator 2 extends along a vertical axis 8.

[0044] FIGS. 2 to 4 show in detail the connection between linkage head 7 and output shaft 9 by means of a connection element 17. In the sectioned view according to FIG. 2, the connection element 17 is hidden for the sake of clarity. In the sectioned view according to FIG. 3, the connection element 17 is shown. In the detailed view according to FIG. 4, an upper side of the linkage head 7 is represented transparently.

[0045] The output shaft 9 is mounted in the door actuator 2 so as to be rotationally movable via corresponding rotary bearings 11. Furthermore, the output shaft 9 is connected to an output element 10, for example a cam wheel or a gear wheel, in a rotationally fixed manner. This drive element 10 is, for example, set into rotation electromotively, whereby the output shaft 9 rotates about the vertical axis 8.

[0046] The output shaft 9 has two opposing face-side ends 15, 16. The end facing the linkage head 7 is defined as the first end 15. The opposing end lying below in the exemplary embodiment shown is defined as the second end 16.

[0047] The output shaft 9 penetrates a hole 12 with inner thread and first nominal diameter 14. A recess 13 is located at both ends 14, 15. The connection element 17 has a head 18, which is recessed in the recess 13 at the second end 16 of the output shaft 9.

[0048] The connection element 17 has an outer thread with second nominal diameter 19. The second nominal diameter 19 is smaller than the first nominal diameter 14 such that there is no screwed connection between connection element 17 and output shaft 9.

[0049] The linkage head 7 has an attachment region 20 on its side facing the output shaft 9. The attachment region 20 has a form closure region 23. In this form closure region 23 sits the outer contour of the output shaft 9 in a positive-locking manner for torque transmission.

[0050] Furthermore, the attachment region 20 has an inner thread 24 in which the connection element 17 is screwed.

[0051] FIG. 5 shows an exemplary embodiment, in which the connection element 17 is fixedly connected to the linkage head 7; in particular the connection element 17 cannot thereby be screwed or rotated with respect to the linkage head 7. The connection element 17 protrudes through the output shaft 9 and is fixed at the second end 16 on the output shaft 9, whereby the connection is made between linkage head 7 and output shaft 9. A nut is screwed onto the connection element 17 on the second end as a pull-out securing mechanism 30.

[0052] FIG. 6 shows an exemplary embodiment, in which the connection element 17 is rotatably connected to the linkage head 7 and protrudes into the output shaft 9. The connection element 17 has an outer thread 32, which can be screwed into an inner thread 32 in the output shaft 9. At the same time as the linkage head 7 is fitted, i.e. moving the linkage head 7 parallel to the vertical axis 8, the connection element 17 is screwed into the output shaft 9. To this end, the connection element 17 is accessible via the second end 16. To this end, the connection element 17 has a tool mount 33.

[0053] In all exemplary embodiments, a hollow space 21 is designed in the linkage head 7 over the attachment region 20. The vertical axis 8 penetrates this hollow space 21. However, the connection element 17 is configured in its length in particular such that it does not protrude or protrudes as little as possible into the hollow space 21.

[0054] As an overview of FIGS. 2 to 6 in particular shows, the hollow space 21 is used for cable routing for a cable 25. This cable 25 runs through the lever 4 and through the hollow space 21 and is guided through a cable channel 22 into the door actuator 2. This cable channel 22 runs at the side of the attachment region 20, but offset parallel to the vertical axis 8.
