Abstract
An access control gate with a mechanical guidance forms one or more access lanes for patrons. First electronic means include a contactless access reader which is connected to a software controlled verification system to identify the access right of patrons, second means comprise two motor driven flaps which protrude from left and right of the lateral lane boundaries into the access lane thereby forming the closed gate threshold 4. The contactless access reader is arranged to capture the access right of the approaching patron short before he approaches the gate threshold 4. The verification system 13 activates the flaps 7 and 7′ when an access right has been approved to swing out of the lane A to indicate to the approaching patron the granted access right. Third means to detect the passage of patrons through the gate threshold comprising two or more photoelectric barriers 10 and 10′, whose detecting beams are distant from each other preferably between 1 and 10 inch, and whose beams are directed to the lane zone behind the gate threshold 4, thereby initiating the flaps 7 and 7′ to close the lane A.

17. A mechanically-guided access control gate for an access lane for patrons, comprising:
-
two motor-driven flaps which protrude from left and right of lateral lane boundaries into the access lane so as to form a closable gate defining a gate threshold, a contactless access reader located before the gate threshold in a passing direction of a patron and connected to a software-controlled verification system which identifies an access right of the patron and causes the motor-driven flaps to swing out of the lane when the access right has been approved, and a detector system located after the gate threshold in the passing direction of a patron and comprising two or more photoelectric barriers having spaced detecting beams, with the detector system detecting passage of the patron through the gate threshold and causing the motor-driven flaps to close after the patron has passed through the gate. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. An access control gate for an access lane, comprising:
-
a motor-driven flap which protrudes from a lateral lane boundary into the access lane, the flap being pivotally mounted proximate to the lane boundary for rotation into a position parallel to the lane boundary, a post located at the lane boundary, a lever forming about one quarter of a circle which is pivotally mounted on the post, thereby allowing the lever to turn from a position outside the lane (open flap) into a position inside of the lane (closed flap) to form a closed gate. - View Dependent Claims (31, 32, 33)
