Revolving door has two fixed curved drum-type walls with spaces for an entry and an exit and a number of door leaves rotating together around a central axis of rotation inside the drum-type walls

摘要

One door leaf (2) is fitted with a supplementary leaf (4) that swivels by means of ball-and-socket joints, which fit in/on a frame section of the door leaf. A locking/stopping mechanism fits on the supplementary leaf's end opposite a ball-and-socket joint. A center of motion for the ball-and-socket joints lies close to the drum-type walls. An independent claim is also included for a night lock for a revolving door.
