Abstract

A passage barrier includes two guide elements that cooperate such that they define a gate region, through which a person passes from an entrance region into a passage region. The passage barrier has a drive with a drive unit and an output unit. The drive unit, output unit, and a barrier element are operatively connected such that the barrier element is movable via the drive unit into a position closing and a position opening the gate region. The output unit has a hollow shaft with outer and inner shell surfaces. The inner shell surface and drive unit are configured such that the inner shell surface surrounds the drive unit and the hollow shaft has a mount for fixing the barrier element on the hollow shaft. The mount is arranged on the outer shell surface and formed integrally with the hollow shaft.

First claim

The invention claimed is:

1. A passage barrier comprising:
a first guide element and a second guide element, wherein
the first guide element and the second guide element cooperate to define a gate region therebetween, through which a person is configured to pass from an entrance region to a passage region;

at least one barrier element, wherein
the barrier element is arranged inside the gate region, wherein
the barrier element, the first guide element and the second guide element cooperate such that a passage of a-the person from the entrance region into the passage region is configured to be prevented or allowed; and

a drive having a drive unit and
an output unit, wherein
the drive unit, the output unit, and the barrier element are operatively connected such that the barrier element is movable by the drive unit into a position wherein the barrier element prevents passage through the gate region and into a position wherein the barrier element allows passage through the gate region wherein wherein
the output unit comprises a hollow shaft, wherein

the hollow shaft has an outer shell surface and an inner shell surfae, wherein
the inner shell surface and the drive unit are configured such that the inner shell surface surrounds the drive unit and

the hollow shaft has a barrier element mount, wherein
the barrier element mount fixes the barrier element on the hollow shaft,
the barrier element mount is arranged on the outer shell surface of the hollow shaft and
the barrier element mount is formed integrally with the hollow shaft,
wherein the inner shell surface includes a torque reception element and the torque reception element comprises a torque reception toothing,
wherein the drive unit comprises at least one torque transmission element configured to transmit torque from the drive unit to the barrier element, wherein the at least one torque transmission element has torque transmission toothing such that when the at least one torque transmission element is inserted into the torque reception toothing, the torque reception toothing engages with the torque transmission toothing to non-movably fix the drive unit to the hollow shaft.

2. The passage barrier, according to claim 1 , wherein the torque reception toothing is formed integrally with the inner shell surface of the hollow shaft.

3. The passage barrier, according to claim 1 , wherein the hollow shaft is formed as an extrusion or cast part.

4. The passage barrier, according to claim 1 , wherein the barrier element mount is substantially U-shaped, wherein the barrier element is fixable between the limbs of the U-shaped barrier element mount.

5. The passage barrier, according to claim 1 , wherein the hollow shaft is mounted to be rotatable with respect to at least one of the first and second guide elements.

6. The passage barrier, according to claim 1 , wherein the drive unit has a drive axis which is coaxial with an axis of rotation of the hollow shaft.

7. The passage barrier, according to claim 1 , wherein the torque reception toothing comprises a first group of torque reception toothing and a second group of torque reception toothing which are geometrically different from one another.

8. A method for manufacturing a passage barrier, wherein
the passage barrier has a first guide element and a second guide element, wherein
the first guide element and the second guide element cooperate to define a gate region therebetween, through which a person is configured to pass from an entrance region to a passage region,

the passage barrier comprises at least one barrier element, wherein
the barrier element is arranged inside the gate region, wherein
the barrier element, the first guide element and the second guide element cooperate such that a passage of the person from the entrance region to the passage region can be prevented or allowed,

the passage barrier has a drive,
wherein the drive has a drive unit and has an output unit, wherein
the drive unit, the output unit and the barrier element are operatively connected such that the barrier element is movable by the drive unit into a position wherein the barrier element prevents passage through the gate region and into a position wherein the barrier element allows passage through the gate region, wherein

the output unit comprises a hollow shaft, wherein
the hollow shaft has an outer shell surface and an inner shell surface, wherein
the inner shell surface and the drive unit are configured such that the inner shell surface surrounds the drive unit and

the hollow shaft has a barrier element mount, wherein
the barrier element mount fixes the barrier element on the hollow shaft,
the barrier element mount is arranged on the outer shell surface of the hollow shaft and
the barrier element mount is formed integrally with the hollow shaft,
wherein the inner shell surface includes a torque reception element and the torque reception element comprises a torque reception toothing,
wherein the drive unit comprises at least one torque transmission element configured to transmit torque from the drive unit to the barrie element, wherein the at least one torque transmission element has torque transmission toothing such that when the at least one torque transmission element is inserted into the torque reception toothing, the torque reception toothing engages with the torque transmission toothing to non-movably fix the drive unit to the hollow shaft,

the method including, in any order, the steps of:
inserting the drive unit into the hollow shaft,
fixing the barrier element to the barrier element mount of the hollow shaft, and
fixing the drive to at least one of the first and second guide elements.
