A door (1) for a T-shaped opening in a wall comprises two door leaves (2, 3) of a flexible material and a number of horizontal cross bars (7-9) guided at their ends by vertical guide rails (20, 21) mounted on the wall. The door leaf (2) is suspended from the top of the opening and has means (12, 17) for hoisting the cross bars (7-9) so that the door leaves (2, 3) fold up. The cross bar (7) is longer than the cross bars (8, 9). The sections (21') of the guide rails (21) guiding the ends of the cross bars (8, 9) are connected with the cross bar (7). Guiding means is provided to ensure that cross bars (8, 9) re- enter the guide rails 21 when the door is being closed. Locking means is also described. <IMAGE> |
