Revolving doors

Such types are provided in public buildings, like banks, museums, hotels, offices etc

A revolving door normally has four wings/leaves that hang on a center shaft and rotate one way about a vertical axis within a round enclosure. The central shaft is fitted with ball bearing arrangement at the bottom, which allows the shutters to move without any jerk and making noise

The radiating shutters may be fully paneled, fully glazed or partly glazed. The glass doors allow people to see and anticipate each other while walking through. Vertical rubber pieces are provided at the rubbing end of the shutter to prevent drought of air.

  People can walk out of and into the building at the same time.   The door closes automatically when not in use.
