MODULAR TILE WITH CONTROLLED DEFLECTION

摘要

A modular tile[100, 600] configured to interlock with multiple tiles to form a modular floor covering over a floor [101, 601]. The tile includes a surface [110, 610] having a periphery defining side walls extending downward from the surface [110, 610], the side walls [122, 622] having a coupling portion [124, 624] configured to couple with other tiles adjacent thereto to form the modular floor covering. The tile [100, 600] also includes a bottom side [112, 612], opposite the surface [110, 610], having a support grid including an array of downward extending post structures in the form of primary post structures [130]. Some of the post structures [130] include at least one resilient end portion [134] with a radial end surface [136] configured to be positioned against the floor [101. 601] to facilitate controlled deflection of the structures. The post structures may comprise primary and secondary post structures [630, 660], with the secondary post structures [660] limiting the deflection of the primary post structures [630].
