Abstract

The disclosure relates to a revolving door assembly ( 1 ) comprising a central column ( 2 ) and at least one door panel connected to the central column ( 2 ) and rotatably arranged around a central axis (X) of the central column ( 2 ). The revolving door assembly ( 1 ) comprises a drive unit ( 6 ) enclosed within the central column ( 2 ), the drive unit ( 6 ) comprising a motor ( 13 ) for rotating the door panel ( 3 ). According to the revolving door assembly, the motor ( 13 ) has a central through hole (H 1 ), wherein one or more cables (C 1 ) of a cable configuration (C) are configured to pass through the central through hole (H 1 ).

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 of the central column, wherein the revolving door assembly further comprises a drive unit enclosed within the central column, the drive unit comprising a motor for rotating the door panel, wherein the motor has a central through hole, wherein one or more cables of a cable configuration are configured to pass through the central through hole, wherein the drive unit comprises a gear operably connected to the motor, wherein the gear has a through hole forming a passage through which one or more cables of the cable configuration are allowed to pass.

2. The revolving door assembly according to claim 1 , wherein the motor has an outer diameter essentially corresponding to an inner diameter of the central column.

3. The revolving door assembly according to claim 1 , wherein the motor is configured to be arranged within the central column so that the central through hole of the motor is coaxially arranged relative to the central axis of the central column.

4. The revolving door assembly according to claim 1 , wherein the central column has an upper side and a lower side, wherein the central column is provided with a passage from the upper side to the lower side via the central through hole of the motor for allowing introduction of cables of the cable configuration from either side of the central column.

5. The revolving door assembly according to claim 1 , wherein the motor is a hollow shaft torque motor.

6. The revolving door assembly according to claim 1 , wherein the motor is a brush motor.

7. The revolving door assembly according to claim 1 , wherein the motor and the gear are arranged within the central column such that one is located above the other, wherein the through hole of the gear is arranged to form a passage for the cables of the cable configuration through both the through hole of the gear and the central through hole of the motor.

8. The revolving door assembly according to claim 1 , wherein the passage of the central column is configured to run via the through hole of the gear.

9. The revolving door assembly according to claim 1 , wherein the cable configuration comprises a cable for powering the motor.

10. The revolving door assembly according to claim 1 , wherein the cable configuration comprises a tube for accommodating cables of the cable configuration, wherein said tube is configured to run through the central through hole of the motor.

11. The revolving door assembly according to claim 1 , further comprising one or more control units, wherein at least one of the one or more control units is arranged above the drive unit or below the drive unit, said one or more control units being configured to facilitate operation of the revolving door assembly, said one or more control units being operably connected to one or more cables of the cable configuration.
