Security system for selectively allowing passage from a non-secure region to a secure region
First Claim
1. A security system for selectively allowing passage of an individual from a non-secure region to a secure region, comprising:
- first revolving door means for selectively allowing passage of a person from the non-secure region to a mid-zone;
second revolving door means spaced apart from the first revolving door means for selectively allowing passage to a secure region;
mid-zone means for securely retaining and observing a person passed from the first revolving door means, the mid-zone means disposed between the first and second revolving door means;
means for observing individuals in the mid-zone means, and a control panel physically separated from the mid-zone means, the control panel comprising an X-ray monitor for remotely viewing objects passed across the X-ray detection system in the mid-zone means;
said control panel comprising a card panel and means for transferring cards from the card panel between the control panel and the mid-zone means.

Abstract
A security system for allowing selective access to a secured area generally comprises first and second three wing center shaft ganged revolving door structures, each partially surrounded by upright facing curved side walls disposed in spaced apart relationship to define a mid-zone. A digital combination lock at the first entryway provides initial access. Any two wings of the revolving doors have an angular span less than that traversed by each side panel to define a lockable detection chamber. A gas ionization explosives detector is coupled to the detection chamber. The mid-zone comprises metal and X-ray detectors and a hand geometry reader. The second revolving door has an entryway actuatable by a pass card reader. The second revolving door provides access to the secure region.
In operation, an individual seeking access punches a combination lock releasing the first revolving door allowing the wings to rotate and then lock, enclosing a detection chamber in which the individual is confined. The explosives detector is actuated and samples air from the chamber to determine if explosives are present. A negative detection response releases the center shaft, the wings rotatable to a position allowing entry to the mid-zone. The individual then passes across the metal detector. Personal belongings are passed through the X-ray device. A badge, obtained at a guard station after palm reader identification, actuates the second revolving door, allowing access to the secure region.

13. A security system for selectively allowing passage of an individual from a non-secure region to a secure region comprising:
-
first revolving door means for selectively allowing passage of a person from the non-secure region toward the secure region, the first revolving door means comprising a plurality of wings and center shaft means for allowing ganged wing rotation, the wings disposed radially about the center shaft, and spaced apart facing side panel means for partially surrounding the wings and defining an accessible entryway adjaent the non-secure region; the wings movable to a locked position enclosing at least a portion of the side panel means and defining an enclosed detection chamber; detection means for providing an indication in response to at least one security test on an individual passing through the system; control logic means for allowing rotation of the center shaft means in response to security detection indications;
second revolving door means spaced apart from the first revolving door means for selectively allowing passage to the secure region;
mid-zone means for securely retaining and observing a person passed from the first revolving door means, the mid-zone means disposed between the first and second revolving door means;
metal detector means for detecting suspect metal devices, the metal detector means coupled to the control logic for preventing rotation of the second revolving door means in response to the presence of suspect metal devices;
weighing means responsive to the weight of an individual in the first revolving door means, the wing means coupled to the control logic means; and
hand geometry reader means disposed within the mid-zone for identifying an individual, the hand geometry reader means coupled to the control logic means. - View Dependent Claims (14, 15, 16, 17, 18, 19)
