Abstract

An access control apparatus has a blocking device (1) that is actuated by an actuator, and an authentication reader (7), upon reading a valid access authorization the blocking device (1) moving into the release position. For detecting a wheel chair (15) and/or pram in the area of the blocking device (1) a sensor (13) is provided, which does not activate the actuator for moving the blocking device (1) from the release position into the blocking position until the wheel chair (15) or pram has left its detection area.

Claims

1. A personal access control apparatus having a blocking device (1), which is activated by an actuator controlled via a control system, and having an authentication reader (7), wherein upon reading a valid access authorization the blocking device (1) is moved from the blocking position into the release position by actuating the actuator, characterized by a single passageway (3) for checking both walking persons and wheel chair users (15) or persons pushing prams, wherein is provided a sensor (13) for detecting a wheel chair (15) and/or pram in the area of the blocking device (1), which does not activate the actuator as to move the blocking device (1) from the release position into the blocking position until the wheel chair (15) or the pram has left its detection area, and a people sensor (11), which activates the actuator such that the blocking device (1) remains in the release position as long as a person is in the detection area (12) of the people sensor (11).

2. The personal access control apparatus according to claim 1, characterized in that the actuator for moving the blocking device (1) into the blocking position is activated after a predetermined period of time after the wheel chair (15) or pram has left the detection area of the sensor (13) for the detection of wheel chairs and/or prams.

3. The personal access control apparatus according to claim 1, characterized in that in the direction of passage (4) after the first sensor (13) for the detection of wheel chairs and/or prams a second sensor (14) for the detection of wheel chairs and/or prams is provided, and the actuator for moving the blocking device (1) into the closed position is not activated before reaching the second sensor (14).

4. The personal access control apparatus according to claim 1, characterized in that the first and/or second sensor (13, 14) for the detection of wheel chairs and/or prams is formed as an inductive sensor.

5. The personal access control apparatus according to claim 4, characterized in that the inductive sensor is arranged as an induction loop in the entrance lane (3).

6. The personal access control apparatus according to claim 1, characterized in that the people sensor (11) is formed as an optoelectronic sensor.

7. The personal access control apparatus according to claim 1, characterized in that the people sensor (11) is formed by a picture recording unit with downstream picture processing system and picture evaluation.

8. The personal access control apparatus according to claim 1, characterized in that the blocking device (1) is formed by a turning blocking device.

9. The personal access control apparatus according to claim 8, characterized in that the turning blocking device has only one barrier arm (2), the barrier arm (2) is turned between the individual blocking positions by 360 degrees and the rotation axis (5) of the turning blocking device (1) in relation to the horizontal line is inclined by 30 degrees to 60 degrees.

10. The personal access control apparatus according to claim 8, characterized in that the turning blocking device has two barrier arms, which are disposed offset one above the other by about 120 degrees and about 240 degrees.

11. The personal access control apparatus according to claim 9, characterized in that the barrier arm (2) and the rotation axis (5) of the turning blocking device (1) enclose an angle of 30 degrees to 60 degrees.

12. The personal access control apparatus according to claim 9, characterized in that upon reading a valid access authorization the access authorization reader activates the actuator in such a way that the one barrier arm (2) in a first partial turn is turned downward from the blocking position into the release position and the actuator for turning the barrier arm (2) in a second partial turn into the blocking position is not activated before the wheel chair (15) or pram has left the detection area of the one or first sensor (13) for the detection of wheel chairs and/or prams.

13. The personal access control apparatus according to claim 12, characterized in that the partial turn from the blocking position downward into the release position is 90 degrees to 270 degrees.
