<p>A revolving door is provided with a number of door wings (2) which can be driven with the aid of a drive mechanism. This comprises a chain (5) running in a substantially horizontal plane along a number of chain wheels (6) in an essentially polygonal path and operatively engaging at least one door wing by means of a carrier means (8). This carrier means comprises two hinged rods (9, 10) which engage the chain at two spaced apart points (A, B) and are interconnected by means of a lever (11) which is movably and driveably connected to the door wing. <IMAGE></p> |
