Abstract

A door actuator arrangement, comprising a door actuator having an output shaft, with the output shaft having a first face-side end and an opposing second face-side end, a linkage, whose linkage head is fitted on the first end of the output shaft and is connected to the output shaft in a rotationally fixed manner and a connection element. The connection element is connected or can be connected at the first end to the linkage head, protrudes into the output shaft and is accessible at the second end to make a connection between linkage head and output shaft.

First claim

The invention claimed is:

1. A door actuator arrangement, comprising:
a door actuator having an output shaft, wherein the output shaft has a first face-side end and an opposing second face-side end,
a linkage having a linkage head fitted on the first face-side end of the output shaft and is connected in a rotationally fixed manner to the output shaft, wherein the output shaft extends along a vertical axis and the linkage head is configured to move parallel to the vertical axis,
and a connection element, which is connected at the first face-side end to the linkage head, protrudes into the output shaft and is accessible at the second face-side end for making a connection between linkage head and output shaft, and
wherein the connection element runs through a hole in the output shaft, wherein the hole has an inner thread with a first nominal diameter, wherein the connection element has an outer thread with a second nominal diameter, wherein the first nominal diameter is greater than the second nominal diameter, such that the connection element fits loosely in the hole of the output shaft whereby there is no screwed connection between the connection element and the output shaft.

2. The door actuator arrangement according to claim 1 , wherein the connection element is a screw introduced from the second face-side end into the output shaft and screwed into the linkage head.

3. The door actuator arrangement according to claim 2 , wherein a head of the connection element is recessed on the second face-side end of the output shaft in the output shaft.

4. The door actuator arrangement according to claim 1 , wherein the connection element is fixedly connected to the linkage head, protrudes through the output shaft and is fixed on the second face-side end, with a pull-out securing mechanism.

5. The door actuator arrangement according to claim 1 , wherein the connection element is rotatably connected to the linkage head.

6. The door actuator arrangement according to claim 1 , wherein the connection element is configured as an expanding mandrel.

7. The door actuator arrangement according to claim 1 , wherein the linkage head comprises an attachment region for connecting to the connection element, wherein one side of the attachment region is facing the output shaft and on an opposing side of the attachment region a hollow space is designed in the linkage head for cable routing.

8. The door actuator arrangement according to claim 7 , wherein a cable channel leads from the door actuator into the hollow space at the opposing side of the attachment region.

9. The door actuator arrangement according to claim 1 , wherein at least one cable is guided through the linkage head into the door actuator.

10. The door actuator arrangement according to claim 1 , wherein the door actuator is configured as a door drive.

11. The door actuator arrangement according to claim 1 , wherein the linkage comprises two levers that are rotatable with respect to one another such that the linkage is configured as a scissors type linkage.

12. The door actuator arrangement according to claim 1 , wherein the linkage comprises a lever connected in a rotationally fixed manner to the output shaft, a slide rail and a sliding piece guided linearly in the slide rail, wherein the lever is connected in a rotationally movable manner to the sliding piece.

13. A door arrangement, comprising the door actuator arrangement according to claim 1 and a door leaf, wherein the door actuator is mounted on the door leaf and the linkage is configured to be mounted on the frame or wall.

14. A method for mounting the door actuator arrangement according to the door actuator arrangement of claim 1 , the method having the following steps:
fitting the linkage head of the linkage on the first face-side end of the output shaft of the door actuator,
and making the connection between linkage head and output shaft by means of the connection element, which is or can be connected at the first face-side end to the linkage head, protrudes into the output shaft and is accessible at the second face-side end for making the connection.
