Arrangement for sliding doors on mobile units

The invention concerns an arrangement for sliding doors of the type where a door leaf ( 3 ) comprises a number (n) of interlinked and jointed sections ( 4:1 - 4: n) in which adjoining sections are able to rotate around a joint axis (A) from a position in which the sections are in alignment with each other to a relative angled position, whereby the door leaf can slide in the door opening ( 6 ) in guides ( 8, 9 ), each of which comprising a first and a second interacting guide element ( 8′, 8″; 9′, 9″ ) arranged on two opposing end edges ( 22, 23 ) of the door leaf and the corresponding sides of the door opening. To obtain a sound insulating door, there is an elastically deformable material between the adjoining and relatively flexible sections ( 4:1 - 4: n) to separate the sections from each other.
