Patent ID: 8596023

Claim:
A tile configured to form a floor covering over a floor, the tile comprising: a top surface; a bottom side, opposite the top surface; and a support grid for elevating the top surface above the floor, the support grid comprising: a plurality of primary support legs extending downward from the bottom side and contacting the floor, the plurality of primary support legs facilitating resilient deflection in a bi-lateral direction under an applied load to the top surface; and a plurality of secondary support legs disposed apart from the primary support legs that limit the deflection of the deflecting primary support legs, wherein the plurality of secondary support legs are shorter than the plurality of primary support legs, wherein the primary support legs further comprise an upper portion and a lower portion wherein the end portion is configured to resiliently deflect against the floor to provide an upward spring force and wherein the end portion has an elongated width for facilitating deflection of the end portion in a bi-lateral direction in response to the applied load and wherein the end portion of a first primary support leg is oriented in a different direction to an end portion of a second primary support leg to deflect in at least two bi-lateral directions.
