Abstract
The ingress to and egress from an access restricted compartment, such as the cockpit in an aircraft, is controlled by a revolving gate () rotatably mounted in a stationary gate frame (). The revolving gate () has a single gate opening () and is rotatable about its central longitudinal axis through predetermined or preselected angular sectors to bring the gate opening () either into alignment with any one opening () of at least two frame openings () at a time, to provide ingress or egress, or to cause said single gate opening () to face a wall (A) of said stationary gate frame () or a closed door () in said stationary gate frame () to close the gate (). In the closed position of the gate () escape from the gate () is prevented by locking the gate in its closed position by at least one arresting bolt that is electrically controllable. The atmosphere in the revolving gate () is also controllable for incapacitating any unauthorized intruder.
