Abstract
Variable floor height tiered stands installed in a gymnasium, auditorium, indoor or outdoor athletic field or the like, including tiered floor members of which displacement in the fore-and-after direction and variation in depth are minimized when their inclination is changed, thereby to maintain constant the planar projected space of the stands in the architectural plan and to eliminate the risk of interference between the stands and any stationary structure in changing the inclination.
