Abstract
Rotating door systems and methods for rotating a plurality of rotatable doors between a closed position and an open position are provided. Each of the rotatable doors may have a height measured in a vertical direction between opposing horizontal edges, a width measured in a horizontal direction between opposing vertical edges, and an axis of rotation centrally located between the opposing vertical edges. The rotatable doors may be rotatably coupled to an upper support at the axis of rotation via an upper pivot shaft and rotatably coupled to a lower support at the axis of rotation via a lower pivot shaft. The rotatable doors may be at least partially transparent. The rotation of one or more of the rotatable doors may be controlled by a controller.
