Arrangement in revolving door assemblies

A revolving door assembly comprising a revolving door rotatable about a longitudinal axis, a stationary structure having a pair of stationary wall sections each having a partial cylindrical configuration, said wall sections being diametrically spaced from one another to define a passage therebetween, said revolving door having outer radial end parts which transcribe a circular path as said revolving door revolves, said wall sections being juxtaposed to said circular path, wall panels each having a partial circular configuration, said wall panels being movably mounted on said stationary structure for movement along a circular path between a closed position and an open position with the center of the last said circular path being coincident with said longitudinal axis, said wall panels in said closed position closing off said passage, said wall panels in said open position being removed from at least parts of said passage to preclude closing-off of said passage, said wall panels being movable between said open and closed positions in synchronism with the rotation of said revolving door as said movable wall panels and said revolving door alternatively open and close-off said passage to provide a draft-free passage as people pass through the revolving door.
