| 摘要 |
The present invention relates to an arrangement in revolving door assemblies, comprising a pair of part-cylindrical wall portions (3,4) partly surrounding the rotational path of a revolving door (5) and partly defining a passage (P). Pairs of part-cylindrical wall panels (10,11;12,13) are provided in association with the part-cylindrical wall portions. Said wall panels are movable along paths concentric with the rotational path of the revolving door and are adapted to close and open the passage substantially in syncronism with the continuous rotation of the revolving door. Thereby passage will remain checked during said rotation, alternatingly by the revolving door alone and by said door in cooperation with wall panels of each pair. Hereby a draught-free passage will be maintained. |
