Estimating the term…
The ingress to and egress from an access restricted compartment, such as the cockpit in an aircraft, is controlled by a revolving gate (1) rotatably mounted in a stationary gate frame (2). The revolving gate (1) has a single gate opening (11) and is rotatable about its central longitudinal axis through predetermined or preselected angular sectors to bring the gate opening (11) either into alignment with any one opening (21) of at least two frame openings (21) at a time, to provide ingress or egress, or to cause said single gate opening (11) to face a wall (2A) of said stationary gate frame (2) or a closed door (51) in said stationary gate frame (2) to close the gate (1). In the closed position of the gate (1) escape from the gate (1) is prevented by locking the gate in its closed position by at least one arresting bolt that is electrically controllable, preferably from the cockpit. The atmosphere in the revolving gate (1) is controllable, preferably also from the cockpit, for incapacitating any unauthorized intruder.
An apparatus for controlling the ingress and egress to and from a restricted compartment, said apparatus comprising an access area including a floor, a gate frame (2) mounted in a fixed position on said floor in said access area, a revolving gate (1) rotatably mounted in said gate frame for rotation about a longitudinal gate axis (A), said gate frame (2) comprising at least two frame openings (21), said revolving gate comprising a single gate opening (11), means for permitting (13) rotation of said revolving gate (1) relative to said gate frame (2) for aligning said single gate opening (11) with but one of said at least two frame openings (21) at a time for ingress and egress into and out of said revolving gate, and controllable stop means for arresting said revolving gate in one of two positions including an alignment position permitting ingress to and egress from said revolving gate (1) and a gate closing position for preventing an unauthorized exit from said revolving gate (1).
