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 and may be optionally retained. The devices can contain multiple rotatable door panels, which can be positioned behind one another. The door panels can be controlled by mechanized arms or other control devices 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

an entryway including two moveable and rotatable door panels operating in conjunction with two linear sidewalls wherein said sidewalls are oriented parallel to one another;

wherein each of said two door panels is driven by a drive mechanism, wherein each of said two door panels rotates between a position perpendicular to said sidewalls and a position parallel to said sidewalls;

from a first position each of said two door panels moves along a first longitudinal direction that is parallel to said sidewalls while simultaneously being fixed in the position perpendicular to said sidewalls to a second position;

from the second position, each of said two door panels rotates to a third position

from the third position each of said two door panels moves along a second longitudinal direction that is parallel to said sidewalls while simultaneously being fixed in the position parallel to said sidewalls to a fourth position; and

from the fourth position, each of said two door panels rotates to the first position.

2. The portal apparatus of claim 1, wherein each drive mechanism is attached to a sliding roof panel located at the top of the door panel, and wherein each sliding roof panel slides in a longitudinal direction that is parallel to the sidewalls.

3. The portal apparatus of claim 2, wherein each drive mechanism is moveable with respect to the sliding roof panel in a lateral direction that is perpendicular to the sidewalls.

4. The portal apparatus of claim 1, further comprising programming for operation supporting bidirectional traffic flow for a first and second subject passing through the portal apparatus successively, the programming causing the portal apparatus to behave according to the steps of:

initially positioning the door panels in a first neutral position approximately in the longitudinal center of the portal apparatus such that a first of the two door panels is perpendicular to the sidewalls and a second of the two door panels is positioned parallel to the sidewalls, the first door panel blocking passage;

wherein as a first subject enters the portal apparatus in the first longitudinal direction, moving the first door panel in the first longitudinal direction while simultaneously moving the second door panel in the second longitudinal direction opposite the first longitudinal direction;

wherein as the second door panel becomes positioned behind the first subject, rotating the second door panel from the position parallel to the sidewalls into a position perpendicular to the sidewalls, thereby in conjunction with the first door panel temporarily forming a detection chamber around the subject;

moving both door panels in the first longitudinal direction while rotating the first door panel to a position parallel to and adjacent to one of the sidewalls, allowing the subject to exit the portal apparatus in the first longitudinal direction; and

with the first door panel positioned parallel to and adjacent to one of the sidewalls, moving the first door panel in the second direction until the first door panel is positioned approximately in the longitudinal center of the portal apparatus, with the second door panel still positioned perpendicular to the sidewalls and blocking passage, thus positioning both door panels in a second neutral position approximately in the longitudinal center of the portal apparatus, the second neutral position being substantially equivalent to the first neutral position except that the positions of the door panels are reversed.

5. The portal apparatus of claim 4, wherein operation of the portal apparatus is reversed for a second subject travelling in a direction opposite the first subject, starting with the door panels in the second neutral position and ending with the door panels in the first neutral position.

6. The portal apparatus of claim 1, wherein at least lateral and longitudinal movement of each door panel is driven at least in part by the drive mechanism, wherein the drive mechanism is located below a floor panel of the entryway.

7. The portal apparatus of claim 6, wherein the drive mechanism located below the floor panel comprises for each moving door panel a moving drive socket that travels in a substantially rectangular path, and is engaged by a drive assembly attached to the door panel that passes through at least one slot in the floor panel.

8. The portal apparatus of claim 7, wherein the drive assembly comprises a multi-tined drive fork that passes through a plurality of slots in the floor panel.

9. The portal apparatus of claim 1, further comprising a sealable passageway on each side of the entryway and adjacent a sidewall for allowing passage of a door panel when the door panel is travelling in a longitudinal direction while positioned parallel to a sidewall.

10. The portal apparatus of claim 9, wherein each sealable passageway has one or more doors at each end that open to allow a door panel to enter, and then close after a door panel has left the passageway.

11. The portal apparatus of claim 9, further comprising a plurality of telescoping extensions contained within each moving door panel, wherein a telescoping extension is deployed to fill a gap between the moving door panel and an opposite sidewall when the moving door panel is perpendicular to the sidewall.

12. The portal apparatus of claim 9, wherein the drive mechanism is located at the top of each door panel, said drive mechanism further comprising a structure for altering the position of the drive mechanism with respect to the door panel, such that the door panel may be rotated around a central axis positioned at a central location on the door panel, or around an axis positioned at a variable distance to either side of the central axis.

13. The portal apparatus of claim 12, wherein each time a door panel is rotated 180°

, the axial position of the drive mechanism is moved to the opposite side of the central axis position.

14. The portal apparatus of claim 1, further comprising an anchor assembly within each door panel that descends vertically for a time period including at least a portion of the duration wherein that door panel is perpendicular to a sidewall, the anchor assembly passing through at least one slot in a floor panel and engaging with a moveable receptacle located below the floor panel.

15. The portal apparatus of claim 14, further comprising a plurality of slots in the floor panel, and wherein the anchor assembly comprises a multi-tined drive fork.

16. The portal apparatus of claim 1, further comprising a brake assembly within each door panel that is deployed in response to a detected side force or impact on the door panel, and wherein a brake device descends to engage with the floor panel and mitigate further side movement of the door panel.

17. The portal apparatus of claim 1, further comprising a plurality of telescoping extensions contained within each moving door panel, wherein a telescoping extension is deployed to fill a gap between the moving door panel and an opposite sidewall when the moving door panel is perpendicular to the sidewall.

18. The portal apparatus of claim 1, wherein for a sequence of pedestrian subjects passing through the portal apparatus in a first direction, a first side of a specific moveable and rotatable door panel will face a first subject and a second side of the specific moveable and rotatable door panel will face a subsequent subject.

19. The portal apparatus of claim 1 wherein the rate of movement of each door panel is automatically adjusted to match a speed of movement a subject.

20. The portal apparatus of claim 1 wherein at least a portion of the drive mechanism for each door panel travels in a substantially rectangular path.

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