ABSTRACT:
An interior arrangement used in an expandable room structure includes a first room section having a stationary floor with an upper surface. A second room section is movable relative to the first section between a retracted position and an extended position to expand the interior volume of the vehicle, and the second room section has a floor with a top surface. A pair of substantially parallel outer rails is provided for supporting the first room section, and a pair of substantially parallel inner rails is provided for supporting the second room section. Each of the inner rails is slidably mounted for longitudinal movement relative to one of the outer rails. An operating mechanism selectively moves the inner rails relative to the outer rails to extend and retract the second room section relative to the first room section. The operating mechanism is constructed and arranged to translate inward and outward movement between the inner rails and the outer rails into substantially vertical movement of the second room section relative to the stationary floor. The operating mechanism includes a gear track extending along a sloped path of travel defined by the inner rails so as to align the top surface of the second room section floor with the upper surface of the stationary floor as the second room section is moved to its extended position, and to vertically offset the top surface of the second room section floor relative to the upper surface of the stationary floor as the second room section is moved to its retracted position. The operating mechanism substantially maintains parallelism between a longitudinal axis of the inner rail and the floor of the second room section, and between a longitudinal axis of the outer rail and the stationary floor over the entire range of movement of the second room section relative to the first room section.
