Abstract

The present invention relates to a passage barrier comprising at least one barrier element that can be swivelled around a swivelling axis inside a swivelling area, at least one sensor technology that detects the presence of a person in the swivelling area and that comprises at least one sending unit emitting detection waves as well as at least one reception unit and an electronic evaluation unit for evaluating the output signals of the sensor technology, wherein the sending unit and the reception unit are located such that a detection wave extending from the sending unit towards the reception unit extends through the swivelling area of the barrier element and wherein the barrier element is at least partially made of a detection wave transparent material. Furthermore, the present invention relates to a method for operating a passage barrier according to the invention.

Claims

1. A passage barrier (10) comprising at least one barrier element (34) that can be swivelled around a swivelling axis inside a swivelling area (38), at least one sensor technology that detects the presence of a person in the swivelling area and that comprises at least one sending unit (40) emitting detection waves as well as at least one reception unit (42) and an electronic evaluation unit for evaluating the output signals of the sensor technology, wherein the sending unit (40) and the reception unit (42) are located such that a detection wave extending from the sending unit (40) towards the reception unit (42) extends through the swivelling area (38) of the barrier element (34) and wherein the barrier element (34) is at least partially made of a detection wave transparent material.

2. A passage barrier (10) according to claim 1, wherein the detection wave transparent material of the barrier element (34) is glass or plastic.

3. A passage barrier (10) according to claim 1 wherein the sending unit (40) is connected to a source generating detection waves via at least one waveguide (44).

4. A passage barrier (10) according to claim 1 wherein the sending unit (40) comprises at least one deviation device (54) for detection waves.

5. A passage barrier (10) according claim 1 wherein the sending unit (40) and the reception unit (42) are provided in partition walls (14, 16, 18) that are arranged opposite each other and that at least partially define a passageway (12) through the passage barrier (10).

6. A passage barrier (10) according to claim 5, wherein the partition walls (14, 16, 18) at least partially comprise a detection wave transparent material.

7. A passage barrier (10) according to claim 1 wherein the passage barrier (10) comprises a sensor technology for detecting the swivelling angle of the barrier element (34).

8. A method for operating a passage barrier (10) according claim 1 wherein the signals of the at least one sensor technology are evaluated in dependence on the swivelling angle of the at least one barrier element (34).
