FIELD: transportation.
SUBSTANCE: invention relates to transport facilities, namely, to variable-volume trailer coach. Residential trailer comprises a closed body, equipped with a wheel chassis and a traction-coupling device, enclosing the bearing shell, pivotally connected by a lower edge of the rear end to the body with possibility of rotation in the vertical plane and configured to cover the housing in the transport position. Side walls of the case and bearing shell are provided with openings. Bearing shell is closed on all four sides and from above, identical in shape to housing and is configured to form one part of roof of residential area front free end when laying trailer. Said free end face of bearing shell is equipped with volume cup-like pad with side walls with openings. Bowl-shaped pad has open rear and bottom sides. At that, the volumetric patch of the back rib of the rear side is hingedly connected to the bearing shell with the possibility of rotation in the vertical plane on the horizontal axis installed at the level of the housing roof, with the unfolded position of the bearing shell. Connection of the pad with the bearing shell enables to form another part of the roof of the second floor by closing the volume of the trailer when the pad is turned against the stop in the housing roof. Shape inner volume shape corresponds to shape of outer surface of said front free end of bearing shell with possibility of its coverage in trailer transport position. Shape of the inner volume of the bearing shell corresponds to the shape of the outer surface of the housing.
EFFECT: increase of internal volume.
