The door has two door leaves (1, 1A) arranged in a closed position within a door portal and including inner edges (1.1, 1.1A). Drive devices pivot the leaves around 90 degree angle in guiding rails. The swivel movement of one guiding rail is controlled during the opening movement of the door in such a manner that the edge (1.1) of the leaf (1) is temporally guided into the opening movement in front of the edge (1.1A) of the leaf (1A). |
