Abstract

A system for controlling access to a restricted-access area in a building has a sliding door system and a controller for the sliding door system. The sliding door system has a door frame and a sliding door which can be moved in the door frame between a closed position and an open position by a drive unit. The door frame has a passage region and a wall shell region which at least partially accommodates the sliding door in the open position. A controller is arranged on the sliding door and is communicatively connected to the drive device. The controller is designed to control a movement of the sliding door between the closed position and an open position. A light projection device is arranged in an interior of the sliding door and is communicatively connected to the controller. The light projection device is designed to project status information specified by the controller for a user requesting access to the restricted-access area as a visible light projection onto a projection surface.

First claim

The invention claimed is:

1. A system for controlling access to a restricted-access area in a building, comprising:
a sliding door system which comprises a door frame and a sliding door which can be displaced in the door frame between a closed position and an open position by means of a drive unit, wherein the door frame has a passage region and a wall shell region which at least partially accommodates the sliding door in the open position;
a controller which is arranged on the sliding door and is communicatively connected to the drive unit, wherein the controller is operable to move the sliding door between the closed position and the open position;
a light projection device which is arranged in an interior of the sliding door and is communicatively connected to the control device, wherein the light projection device is operable to project status information specified by the control device for a user who requests access to the restricted-access area, as a visible light projection onto a projection surface; and
wherein the sliding door has an inner door leaf facing the restricted-access area and an outer door leaf facing away from the restricted-access area, between which the interior extends, wherein the outer door leaf has a control compartment extending into the interior, wherein the light projection device is operable to emit the light projection into the control compartment.

2. The system according to claim 1 , in which the projection surface is arranged in the control compartment and extends between the inner door leaf and the outer door leaf, so that the projected status information for the user requesting access is visible.

3. The system according to claim 1 in which the light projection device is arranged to project the status information onto the projection surface arranged in the control compartment and/or a floor area in front of the sliding door.

4. The system according to claim 1 , further comprising a detection device which is arranged on the sliding door and communicatively connected to the controller, wherein the detection device is operable to detect a manual interruption of the projected status information.

5. The system according to claim 4 , in which the detection device comprises a light barrier.

6. The system according to claim 1 , further comprising a detection device which is arranged on the sliding door system or in a vicinity of the sliding door system and is communicatively connected to the controller wherein the detection device is operable to check an access authorization of the access-requesting user.

7. The system according to claim 6 , in which an recognition device comprises a camera device, wherein the recognition device is operable to carry out a method for facial recognition.

8. The system according to claim 7 , in which the detection device is operable to generate a status signal when the user requests access, and in which the control device is operable to activate the light projection device when a status signal is present.

9. The system according to claim 6 , in which an identification device comprises a radio device, wherein the identification device is operable to capture and check credentials presented by the user, wherein the controller is operable to initiate movement of the sliding door according to a stored opening width if the credentials are valid for the user.

10. The system according to claim 1 , wherein the sliding door comprises an actuator which is operable to position the inner door leaf and the outer door leaf of the sliding door in a first position with a first leaf spacing when the sliding door is in the closed position and in a second position with a second leaf spacing when the sliding door is in the open position, wherein the first leaf spacing is greater than the second leaf spacing.

11. A method for operating the system for controlling access to a restricted-access area in a building according to claim 1 , wherein the system comprises a sliding door system and a controller for the sliding door system, the method comprising:
controlling a light projection device by the controller, wherein the light projection device is arranged in an interior of a sliding door of the sliding door system and is communicatively connected to the controller, wherein the light projection device is controlled by the control device in order to project status information specified by the controller for a user requesting access as a visible light projection onto a projection surface; and
detection of a manual interruption of the projected status information.

12. The method according to claim 11 , in which the status information is projected by the light projection device onto a projection surface in a control compartment of the sliding door and/or onto a floor area in front of the sliding door.

13. The method according to claim 11 , further comprising detection of the user by a detection device which is arranged on the sliding door system or in a vicinity of the sliding door and is communicatively connected to the controller, wherein the light projection device is activated when the user is detected.

14. A system for controlling access to a restricted-access area in a building, comprising:
a sliding door system which comprises a door frame and a sliding door which can be displaced in the door frame between a closed position and an open position by means of a drive unit, wherein the sliding door has an interior and the door frame has a passage region and a wall shell region which at least partially accommodates the sliding door in the open position, wherein the sliding door has an inner door leaf facing the restricted-access area and an outer door leaf facing away from the restricted-access area, between which the interior extends;
a controller which is arranged on the sliding door and is communicatively connected to the drive unit, wherein the controller is operable to move the sliding door between the closed position and the open position; and
a light projection device which is arranged in the interior of the sliding door and is communicatively connected to the control device, wherein the light projection device is configured to project status information specified by the control device for a user who requests access to the restricted-access area, as a visible light projection onto a projection surface, wherein the outer door leaf has a control compartment extending into the interior, wherein the light projection device is operable to emit the light projection into the control compartment.

15. The system according to claim 14 further comprising a detection device which is arranged on the sliding door and communicatively connected to the controller, wherein the detection device is operable to detect a manual interruption of the projected status information.

16. The system according to claim 14 further comprising a detection device which is arranged on the sliding door system or in a vicinity of the sliding door system and is communicatively connected to the controller wherein the detection device is operable to check an access authorization of the access-requesting user.

17. The system according to claim 14 wherein the sliding door comprises an actuator which is designed to position two mutually spaced, substantially parallel door leaves of the sliding door in a first position with a first leaf spacing when the sliding door is in the closed position and in a second position with a second leaf spacing when the sliding door is in the open position, wherein the first leaf spacing is greater than the second leaf spacing.
