Abstract:
An improved athletic flooring substructure of the type that is flexible, resilient, anchored, ventilateable, and DIN certifiable, wherein the improvement comprises;a) a prefabricated ladder-shaped subfloor subassembly wherein, the long outside strips of the ladder-shape are boards having a maximum thickness of one inch and a minimum thickness of three eighths of an inch, b) a multiplicity of transverse anchor strips secured below the long strips, said anchor strips being formed of boards having a maximum thickness of one inch and a minimum thickness of three eighths of an inch, c) resilient pads formed of hydrophobic material secured to the bottom of the anchor strips, d) anchors engaged with the anchor strips and secured in a base so that the anchor strips are free to flex downward against the resilience of the pads while their upward flexure is restrained by the anchors, and e) the subassemblies are secured to the base so that their long strips are parallel and evenly spaced apart so as to create an open channel between subassemblies through which ventilating air can pass freely.
