Abstract
An emergency exit revolving door apparatus includes a revolving door assembly that is generally comprised of a ceiling panel, a floor panel, and a pair of curved vertical panels extending therebetween to form a rigid, conjoint assembly. The revolving door assembly is disposed in a door opening of a building, and is mounted on a dolly that is disposed within a channel inset in the floor and extending outwardly from the exterior of the door opening. In an emergency situation, if a throng of people rush to the revolving door and push outwardly on it with sufficient force, the door assembly will be driven outwardly by the force. The dolly will translate along the channel so that the entire revolving door assembly translates outwardly from the door opening of the building and clear the door opening to enable a substantially unobstructed emergency exit path.
