Access control apparatus
First Claim
1. A personal access control apparatus for checking both walking persons and wheel chair users or persons pushing prams through a single passageway having one direction of travel, wherein the walking persons, wheelchair users, and people pushing prams travel on an entrance lane surface, the personal access control apparatus comprising a blocking device having a barrier arm, which is activated by an actuator controlled via a control system, and an authentication reader, wherein upon reading a valid access authorization the blocking device is moved from a blocking position into a release position by actuating the actuator, the access control apparatus further comprising a wheel chair and/or pram sensor including a continuous induction loop that is embedded below the entrance lane surface and below the barrier arm in the blocking position, a first end of the induction loop being disposed along the direction of travel before the barrier arm when the barrier arm is in the blocking position and a second end of the induction loop being disposed after the barrier arm along the direction of travel whereby the first and second ends define a first area adjacent the blocking device, the wheel chair and/or pram sensor for distinguishing the presence of a wheel chair and/or pram in the first area adjacent the blocking device from the presence of a person, wherein the wheel chair and/or pram sensor does not activate the actuator so as to move the barrier arm from the release position into the blocking position until the wheel chair and/or the pram has left the area of the induction loop, and a people sensor for controlling the actuator so that the blocking device remains in the release position after the wheel chair and/or pram has left the area of the induction loop as long as a person is in a detection area of the people sensor.

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.

12. A personal access control apparatus for detecting walking persons, wheel chair users and persons pushing prams along a passageway having a single direction of travel wherein the walking persons, wheelchair users, and people pushing prams travel on an entrance lane surface, comprising:
-
a blocking device including a barrier arm having a blocking position and a release position for use with a passageway having an entrance side and an exit side; an actuator for operating the blocking device; an authentication reader for reading a valid access authorization and providing an authentication output; a people sensor for sensing the presence of a person within a detection area and providing a people sensor output, wherein a portion of the detection area is disposed on the entrance side of the barrier arm when the barrier arm is in the blocking position; a first wheel chair and/or pram sensor comprising a continuous induction loop that is embedded below the entrance lane surface for distinguishing the presence of a wheel chair and/or pram in a first area adjacent the blocking device from a person and providing a first sensor output, a first end of the induction loop extending beyond the blocking device toward the entrance side and a second end of the induction loop extending beyond the blocking device toward the exit side of the passageway; and a control system for controlling the actuator for the blocking device, the control system receiving the authentication output, the people sensor output, and the first sensor output, wherein the control system controls the actuator to move the blocking device to the release position after receiving the authentication output indicating that a valid access authorization has been received, wherein, in response to the people sensor output, the control system prevents the actuator from moving the blocking device from the release position to the blocking position so long as a person is sensed in the detection area by the people sensor, and wherein, in response to the first sensor output, the control system prevents the actuator from moving the blocking device from the release position to the blocking position until the wheel chair and/or the pram has left the first area of the blocking device and the people sensor does not sense the presence of a person in the detection area. - View Dependent Claims (13, 14)
