Schwenktür

A Schwenktür, often translated as a swing door or revolving door depending on its specific design and context, is a type of door that pivots on a central axis. Unlike traditional hinged doors that swing outwards or inwards on side hinges, a Schwenktür rotates around a vertical spindle. This rotation allows for movement in both directions.

The most common form of Schwenktür is the revolving door, characterized by multiple panels (usually three or four) that are equally spaced around a central shaft. As one panel is pushed, the entire door assembly rotates, allowing people to enter or exit while creating a continuous seal between the interior and exterior environments. This design is highly effective at preventing air infiltration, thereby reducing energy loss and maintaining comfortable indoor temperatures. Revolving doors are frequently found in the entrances of large commercial buildings, hotels, and airports.

A simpler variation can be found in some industrial or kitchen settings, where a single, lightweight panel pivots on a central hinge. These doors are often designed to swing open with a light push and close automatically, facilitating easy passage for personnel or goods while minimizing the spread of odors or drafts. The term Schwenktür can encompass both these types of pivoting doors, with the specific English translation depending on the exact mechanism and application.
