Abstract

A revolving door assembly is disclosed. The door comprises a central column and at least one door panel connected to the central column and rotatably arranged around a central axis (X). The central column comprises a drive unit. The drive unit comprises a motor and an oscillating gear. The oscillating gear comprises at least one rod through hole. A non-rotating support rod passes through the rod through hole and supports the motor. Also disclosed is a driving base unit for a revolving door assembly.

First claim

The invention claimed is:

1. A revolving door assembly comprising
a central column and at least one door panel connected to the central column and rotatably arranged around a central axis, wherein the central column comprises a drive unit, wherein the drive unit comprises a motor ( 13 ) and an oscillating gear, wherein the gear comprises at least one rod through hole, and wherein a non-rotating support rod passes through the rod through hole and supports the motor.

2. A revolving door according to claim 1 , wherein the oscillating gear further comprises a gear through channel ( 12 ).

3. A revolving door assembly according to claim 1 or 2 , wherein the rod through hole of the gear connects a top side of the gear with a bottom side of the gear.

4. A revolving door assembly according to claim 2 , wherein the gear comprises an oscillating part, and wherein the oscillating part comprises the rod through hole.

5. A revolving door assembly according to claim 4 , wherein the rod through hole is arranged displaced from the center of the oscillating part.

6. A revolving door assembly according to claim 4 , wherein the gear through channel is arranged in the center of the oscillating part.

7. A revolving door assembly according to claim 1 , wherein the oscillating gear is arranged to transform a rotating movement from the motor into an oscillating movement in the gear and back to a rotating movement of the door panel.

8. A revolving door assembly according to claim 1 , wherein the central column comprises a driven column and a driving base unit, wherein the driving base unit comprises the drive unit, the support rods and the motor, and wherein the motor is connected to the support rods.

9. A revolving door assembly according to claim 1 , wherein the support rod is static.

10. A revolving door assembly according to claim 1 , wherein the motor is arranged offset in relation to the center axis of the revolving door assembly.

11. A revolving door assembly according to claim 1 , wherein the motor is arranged offset in relation to an input member of the gear.

12. A revolving door assembly according to claim 1 , wherein the revolving door assembly is freestanding.

13. A driving base unit for a revolving door assembly comprising a central column and at least one door panel connected to the central column and rotatably arranged around a central axis, wherein the driving base unit comprises a drive unit, wherein the drive unit comprises a motor and an oscillating gear, wherein the oscillating gear comprises at least one rod through hole, and wherein a non-rotating support rod passes through the rod through hole and supports the motor.

14. A driving base unit according to claim 13 , wherein the oscillating gear comprises a gear through channel.
