    (54) A telescopic door assembly


    (57) A telescopic door assembly comprises a high speed door (2) and a low speed door (3) mounted on a single common track 1 by means of rolling assemblies (5L, 5R; 4L, 4R). The rolling assemblies (5L, 5R) of the high speed door (2) are positioned on the track 1 between the rolling assemblies (4L, 4R) of the low speed door (3).
    By using only a single track 1 instead of two tracks, as is conventional, there are no alignment problems and the mounting of the track to the door lintel 18 can be simplified. Also, the need for spacer elements and the like are eliminated.
