REVOLVING DOOR

摘要

An improved revolving door has a rotary device with door leaves (15) mutually offset around its circumference. The swivelling axis bolts (17) of the door leaves (15) are located with respect to the radial length of the leaves at a minimum distance from the central or symmetry axis (9) which equals at least 70 % of the total length of the leaves. Every two doors (15) may swivel in opposite directions around their swivelling axis (17) between their usual working position and an opening position which leaves a passage free.
