A mobile home is comprised of two telescopingly interconnected box-like parts, the main home part running on wheels while the extension part may be glidably moved between a transport position and an extended position. A pair of superposed pulleys is mounted on each side wall of the extension part at the inner end thereof and the lower pulleys cooperate with guide rails in the main part so that they may run as rollers along the rails for glidably moving the extension part with respect to the main part. A cable is trained over each pair of pulleys in zigzag arrangement and the end portions of the cables are anchored respectively at the open end and the opposite end wall of the main part, the cables being tensioned between the anchors in the zigzag arrangement. A force-transmitting connection is provided between the end portions anchored at the end wall and, if desired, both end portions of the cables may be interconnected to form an integral cable. |
