Revolving Doors
Doors consisting of four leaves at right angles that revolve on centre pivots inside a vestibule.

wood and glass revolving doors
Hardwood and glass doors with brass fittings.

The general reason for these doors is to speed up traffic flow, and at the same time they perform the function of an air lock in minimising the loss of conditioned air.

These doors are just about the ultimate in pivot doors. They usually consist of one double sized door with two half sized doors fixed to them to make a cross. the two smaller doors are fixed via brackets and hinges so that they can be used in the standard position as seen in the photos, but they all have the ability to fold flat so that when they are centred traffic of goods can be carried through both sides at the same time. This ability to over ride the revolving function is mandatory under fire safety regs. In many cases modern doors do this automatically in fire emergencies.

Chrome plated steel and glass doors.

The convention for these doors seems to be that if you are looking in plan then the doors rotate anti-clockwise. Each leaf of these doors is known as a wing. Most examples are rotated by people pushing against the bars, but some of them are automatic, activated by sensors and when not in use they return to a closed position.
