ABSTRACT:
A functional compartment is provided in a building, a sliding frame is mounted in this compartment, connected with jack mechanisms; with the help of these mechanisms the sliding frame can slide beyond the outer limits of the building and back. Smooth and safe sliding of the frame is ensured by its supporting wheels sliding in guiding rails mounted in the surfaces of the functional compartment. The sliding frame is equipped in its front part, with a receiving panel with the right and left “pocket” guiders on it. The attachable section of the H-shaped rail is equipped with a mounting panel, with the similar square structure as of the receiving panel. The thickness of the mounting panel is less than a clearance between the “pocket” guiders and the outer surface of the receiving panel. The receiving panel is supplied with beveled guiding sides, and the mounting panel—with lower rounded corners.
