Abstract

A rapid access door system is provided wherein authorized individuals may pass through the door system and wherein unauthorized individuals are blocked from entering a secured area past the doors and are automatically rerouted to an unsecured area for further processing without blocking the door system and impeding the flow of other individuals entering the door system. The door system uses modular units employing sensing means and a specially configured door which door automatically provides the rerouting of persons in the system. The sensing means determines, among others, the number of persons in the system, whether the door is opened or closed, whether a person has exited the system to particular areas, alerting speakers and signage, with the above information being used in conjunction with the door system to provide a highly efficient and effective rapid access portal system.

Dependent claims

A rapid access door system comprising:

an entrance having authorization means for authorizing a person to pass therethrough;
an aisle extending from the entrance to a bi-fold door and past the bi-fold door to a secure area;
a doorway situated before the bi-fold door on one side of the aisle for exiting the aisle to an unsecure area;
the bi-fold door which is pivotable on vertical axes and is fixedly secured at one pivot axis to the aisle;
to means for moving the bi-fold door based on the authorization means on a third pivot axis along a line parallel to the aisle;
and
wherein when the bi-fold door is in a closed first position, the door blocks the aisle to the secure area and the doorway is open to the unsecure area and when the bi-fold door is in an open second position, the aisle is open to the secure area and the door blocks the doorway to the unsecure area.
