-16- Abstract A revolving door system has a central axis defining center shaft and three wing hangers rigidly joined and extending in equidistant spaced apart rela- tionship about the center shaft's upper portion. Pivots couple three planar upright wings in closely spaced apart relationship to the center shaft. A magnetic latch on each wing hanger is spaced apart from the central axis more remote than the pivot, releasably maintaining the wings in ganged alignment with the hangers. A pair of facing substantially semicircular walls, spaced apart to define regions of ingress and egress, partially surrounds the wings and shaft on oppo- site sides. Each wall has two adjacent movable side panels hanged on opposite sides of a center panel, movable from a nominally enclosing position to an open panic position. In a panic situation, release of the latch allows the wings to be released from the hangers and pivoted freely while the side panels are allowed to pivot about the hinges to enhance the egress frontage to thereby potentially increase the flow of people exiting from the building structure.
