Rotating door for building

摘要

The door has the door leaves held between at least two fixed drum-wall sections, which rotate around a central axis. The door in the area of the floor and top is guided in rotary bearings. Each leaf is normally radial to the central axis and extends outwardly. The stopped leaf can be pivoted over a supplementary axis over the normal position. The supplementary axis (5) is attached to the door leaf by bearing lugs (6) and move against an elastic return gas cylinder (7) for rotation on a bearing plate on the same central axis (4).
