Modular tile with controlled deflection

摘要

A modular tile configured to interlock with multiple tiles to form a modular floor covering over a floor. The tile includes a top surface having a periphery defining side walls extending downward from the top surface, the side walls having a coupling portion configured to couple with other tiles adjacent thereto to form the modular floor covering. The tile also includes a bottom side, opposite the top surface, having a support grid including an array of downward extending polymeric post structures, at least some of the post structures including at least one resilient end portion configured to be positioned against the floor to facilitate controlled deflection of the post structures. The post structures may comprise primary and secondary post structures, with the secondary post structures limiting the deflection of the primary post structures.

1. A tile configured to form a floor covering over a floor, said tile comprising:
a top surface having a periphery defining side walls extending downward from the top surface; and a bottom side substantially perpendicular to the side walls, opposite the top surface; and an array of support structures extending downward from said bottom side, at least some of the support structures comprising deflecting primary support structures that deflect at angle with respect to the bottom when subjected to a threshold load, and at least some of the support structures comprising different height secondary support structures that limit the angular deflection of the deflecting support structures.
