Abstract

Electro-mechanical and electronically controlled access devices are described for controlling access to a building, premises or area in a secure manner such that a subject who is deemed ineligible for access will be barred entry. The devices contain multiple rotatable and moveable door panels. The door panels can be controlled by various drive mechanisms in order to control the passage through the device. The direction of flow through a device according to these embodiments is electronically controlled and may be changed at any point in time. At any instant in time, the flow through the device is unidirectional. Multiple devices can be stacked together to form clusters, which can be controlled according to traffic, time of day, or other factors.

Claims

1. A portal apparatus for securely controlling passage, said apparatus comprising:

a passageway including at least two moveable and rotatable door panels operating in conjunction with at least two sidewalls including at least one linear sidewall;

wherein each of said at least two door panels rotates to a first position perpendicular to said at least one linear sidewall and a second position parallel to said at least one linear sidewall;

wherein in a unidirectional direction of traffic flow through the passageway and while a specific one of said at least two moveable and rotatable door panels is within the passageway, a first side of the specific one of said at least two moveable and rotatable door panels will face in the direction of traffic flow while in the first position during a first traversal of the passageway in the direction of traffic flow by said specific door panel, and a second side of the specific one of said at least two moveable and rotatable door panels will face in the direction of traffic flow while in the first position during a second traversal of the passageway in the direction of traffic flow by said specific door panel.

2. The portal apparatus of claim 1, wherein each of said moveable and rotatable door panels moves in a closed circuit path, and during a circuit of travel along the closed circuit path each of said moveable and rotatable door panels moves in both a longitudinal direction that is parallel to the at least one linear sidewall and a lateral direction that is perpendicular to the at least one linear sidewall, wherein for each of said moveable and rotatable door panels the first position is reached along the closed circuit path while moving in the longitudinal direction and while within the passageway, and wherein for each of said moveable and rotatable door panels the second position is reached along the closed circuit path while not within the passageway.

3. The portal apparatus of claim 2, wherein the closed circuit path has a rectangular shape with rounded corners.

4. The portal apparatus of claim 2, wherein the closed circuit path has a quasi-trapezoidal shape with rounded corners.

5. The portal apparatus of claim 2, wherein each door panel is driven at least in part by a first drive mechanism, and the first drive mechanism moves in a closed circuit track following the closed circuit path.

6. The portal apparatus of claim 5, wherein the first drive mechanism is moved along the closed circuit path by a drive belt or cable that is in turn driven.

7. The portal apparatus of claim 6, wherein an additional belt or cable is provided within the closed circuit path and in contact with the first drive mechanism, such that a differential in movement rate between the drive belt or cable and the additional belt or cable will cause a rotation of the door panel driven by the first drive mechanism.

8. The portal apparatus of claim 5, wherein each door panel is driven at least in part by a second drive mechanism that comprises a conveyor mechanism.

9. The portal apparatus of claim 2, wherein the portal apparatus is capable of bi-directional operation under electronic control, wherein traffic flow comprises two successive subjects passing through the passageway travelling in opposite directions to each other.

10. The portal apparatus of claim 2, further comprising a separate sealable passageway adjacent the at least one linear sidewall, said sealable passageway being sealable on both entry and exit sides of the portal apparatus, said separate sealable passageway allowing passage therethrough of each moveable and rotatable door panel when the door panel is travelling in the longitudinal direction while rotatably positioned parallel to the at least one linear sidewall.

11. The portal apparatus of claim 2, wherein at least one of said at least two sidewalls includes a moveable brake surface that is deployed in response to a detected side force or impact on the moving door panel while it is within the passageway, and wherein the moveable brake surface moves to engage with the moving door panel to mitigate further movement of the door panel resulting from the side force or impact.

12. The portal apparatus of claim 2, further comprising a companion attendant portal, the companion attendant portal comprising first and second chambers and three electronically controlled doors;

wherein a first of the electronically controlled doors is located between a non-secure area and the first chamber;

wherein a second of the electronically controlled doors is located between the first chamber and the second chamber; and

wherein a third of the electronically controlled doors is located between the second chamber and a secure area.

13. The portal apparatus of claim 1:

wherein each of said at least two door panels rotates to the first position while moving in a first longitudinal direction; and

wherein each of said two door panels moves in a second longitudinal direction that is parallel to said at least one linear sidewall while simultaneously being fixed in the second position wherein the second longitudinal direction is substantially opposite the first longitudinal direction.

14. The portal apparatus of claim 13, wherein each door panel is driven at least in part by a first drive mechanism that comprises one or more conveyor mechanisms.

15. The portal apparatus of claim 14, wherein each door panel further comprises one or more engagement drive points located at each end of the door panel and capable of being activated to engage and disengage with the one or more conveyor mechanisms.

16. The portal apparatus of claim 14, wherein each of the one or more conveyor mechanisms further comprises a plurality of engagement drive points capable of being activated to engage and disengage with each of the two or more door panels.

17. The portal apparatus of claim 14, wherein each door panel is guided at least in part by a track mechanism that follows a closed circuit path.

18. The portal apparatus of claim 14, wherein each door panel is driven at least in part by a second drive mechanism, and the second drive mechanism moves in a closed circuit track following a closed circuit path.

19. The portal apparatus of claim 13, wherein the portal apparatus is capable of bi-directional operation under program control, wherein successive subjects passing through the portal apparatus travel in opposite directions.

20. The portal apparatus of claim 13, further comprising a separate sealable passageway adjacent the at least one linear sidewall, said sealable passageway being sealable on both entry and exit sides of the portal apparatus, said separate sealable passageway allowing passage therethrough of each moveable and rotatable door panel when the door panel is travelling in the longitudinal direction while rotatably positioned parallel to the at least one linear sidewall.

21. The portal apparatus of claim 13, wherein at least one of said at least two sidewalls includes a moveable brake surface that is deployed in response to a detected side force or impact on a moving door panel while it is within the passageway, and wherein the moveable brake surface moves to engage with the moving door panel to mitigate further movement of the door panel resulting from the side force or impact.

22. The portal apparatus of claim 13, further comprising a companion attendant portal, the companion attendant portal comprising first and second chambers and three electronically controlled doors;

wherein a first of the electronically controlled doors is located between a non-secure area and the first chamber;

wherein a second of the electronically controlled doors is located between the first chamber and the second chamber; and

wherein a third of the electronically controlled doors is located between the second chamber and a secure area.
