DOOR ACTUATOR LINKAGE

Abstract

A door actuator linkage includes a lever extending along a longitudinal axis, which merges into a linkage head with an offset, wherein the linkage head is formed for rotationally fixed mounting on an output shaft of a door actuator, wherein a free space for cable routing is formed by the offset. The free space is delimited by the linkage head and by an offset surface of the lever, wherein the lever protrudes up to an imaginary boundary surface, which is defined perpendicular to the longitudinal axis. The offset surface is withdrawn partially from this boundary surface in order to expand the free space.

DETAILED DESCRIPTION OF THE DRAWINGS

[0044] A revolving door assembly 200 having a door actuator assembly 100 together with door actuator linkage 1 is described in detail below on the basis of all figures.

[0045] FIG. 1 shows a revolving door assembly 200 having a frame 201 and a door leaf 202 accommodated in the frame 201 in a rotationally movable manner. The revolving door assembly 200 also comprises the door actuator assembly 100.

[0046] The door actuator assembly 100 comprises a door actuator 101 having an output shaft 102, formed here as a door drive. The output shaft 102 rotates about a shaft axis 103. The door actuator 101 is fastened on the door leaf 202. The door actuator assembly 100 also has the door actuator linkage 1. In the example shown, the door actuator linkage 1 comprises a lever 2, which is connected to a slide piece 5 in a rotationally movable manner. The slide piece 5 is guided in a slide rail 4 in a linearly movable manner. The slide rail 4 is fastened on the frame 201.

[0047] The detailed structure of the door actuator linkage 1 emerges in particular from FIGS. 2 to 7.

[0048] The lever 2 merges into the linkage head 3 with an offset 6. A free space 9 results from this offset 6. The shaft axis 103 runs through this free space 9 since the free space 9 is located over the output shaft 102.

[0049] An underside of the free space 9 is delimited by the upper side of the linkage head 3. An offset surface 7 forms a lateral boundary of the free space 9. This offset surface 7 results from the offset 6. In the exemplary embodiment shown, the offset surface 7 is formed by an end face side of the lever 2 facing the shaft axis 103.

[0050] The offset 6 results in the offset surface 7 on the one side and results in a shoulder 8 on the opposing lower side of the door actuator linkage 1 in the example shown. As the representation in FIG. 2 shows, the lever 2 protrudes over the door leaf 202 and extends downwards through the offset 6 with the linkage head 3 to enable a connection to the output shaft 102. The shoulder 8 thereby engages behind the door leaf 202.

[0051] For example, FIGS. 3 and 5 show an imaginary boundary surface 10. This imaginary boundary surface 10 is perpendicular to a longitudinal axis 11 of the lever 2 and parallel to the shaft axis 103. At the same time, the foremost end of the lever 2 or of the offset surface 7 defines the position of this imaginary boundary surface 10. The offset surface 7 is withdrawn from the boundary surface 10 in order to thus configure the free space 9 to be as large as possible.

[0052] In the exemplary embodiment shown, the offset surface 7 is formed with an oblique section 12 obliquely to the longitudinal axis 11 and thereby adopts an angle α of approx. 35°. This oblique section 12 extends from an acute angled end 15 to an obtuse angled end 16.

[0053] FIGS. 3 and 4 show a variant, in which the offset surface 7 has an oblique section 12 and an abutment section 13. The abutment section 13 is formed by an additional element 14 in the construction shown. This additional element 14 is to be assigned to the lever 2. The abutment section 13 can also be formed by an integral portion of the lever.

[0054] FIG. 5 shows that the entire offset surface 7 can also be formed by the oblique section 12 such that the acute angled end 15 of the oblique section 12 protrudes up to the imaginary boundary surface 10.

[0055] The advantage of the abutment section 13 in its convex configuration emerges when viewing FIGS. 3 and 4. These figures show guidance of a cable 18 through the free space 9. The door actuator linkage 1 can be rotated relative to the door actuator 101 by up to 180°. Such a rotation is discernible when viewing FIGS. 3 and 4. The cable 18 comes into contact with the abutment section 13 in the case of the rotation represented in FIG. 4 and in the case of an even further rotation. Through the concave configuration of the abutment section 13, a defined bending is predefined with the largest possible radius of the cable 18.

[0056] FIGS. 3 and 4 illustrate that a cable channel 19 is formed laterally offset to the longitudinal axis 11 next to the lever 2. The cable 18 runs through this cable channel 19. The cable channel 19 is located inside a lever cladding 20.

[0057] The cable channel 19 opens into the free space 9 at the obtuse angled end 16.

[0058] FIGS. 3 and 4 also show that the door actuator linkage 1 comprises a pivot member 17. This pivot member 17 is fixedly connected to the door actuator 101 and serves to divert the cable routing from the substantially horizontal cable routing in the free space 9 to a perpendicular routing in the direction of the door actuator 101.

[0059] The pivot member 17 is located radially outside of the linkage head 3 and radially inside of a radial cladding 21. This radial cladding 21 surrounds the linkage head 3 and laterally delimits the free space 9, in addition to the offset surface 7.

[0060] An upper side of the free space 9 opposite the linkage head 3 can be closed by a free space cladding, which is not represented. This free space cladding then forms the upper boundary of the free space 9. The upper side of the lever 2 can also be clad accordingly.

[0061] FIG. 6 illustrates a radial distance 22, measured perpendicular to the shaft axis 103, from the shaft axis 103 to the outer edge of the linkage head 3. This radial distance 22 must be configured to be correspondingly small since otherwise the shoulder 8 (see FIG. 2) would collide with the door leaf 202. Therefore, the overlap surface between lever 2 and linkage head 3 is also delimited. FIG. 6 illustrates that a material accumulation 23 is applied on the linkage head 3. At this point, an overlap of lever 2 and linkage head 3 and welding of these two elements, in particular a flat welding by a resistance welding method takes place.

[0062] FIGS. 5, 6 and 7 show that the linkage head 3 has a form closure element 24. This form closure element 24 comprises an inner polygonal edge for inserting on the output shaft 102.

[0063] FIG. 7 illustrates that the form closure element 24 is releasable from the remaining component of the linkage head 3 in a non-destructive manner. As a result, the form closure element 24 is interchangeable and/or mountable on the linkage head 3 in different rotational positions relative to the linkage head 3.
