Expandable room flat floor system utilizing notched inner rails and ramped outer rails

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