Patent ID: 7127857

Claim:
A subfloor assembly for supporting a floor on a substrate, the subfloor assembly comprising: a first subfloor including a plurality of first plates wherein each first plate has an associated recess that extends upwardly into the first plate from a lower surface of the first plate along an axis of the first plate and an associated ridge disposed in the recess which extends downwardly from a top surface of the recess to a height above the lower surface of the first plate; a second subfloor including a plurality of second plates wherein the first subfloor is disposed underneath the second subfloor; and a resilient member located in each recess in contact with the ridge which extends downwardly from the top surface of the associated recess; wherein the resilient elastic modulus of the resilient member results in the resilient member being spaced from the top surface of the recess from which the ridge downwardly extends when the first plate associated with the recess and the ridge is in an unloaded state and results in the resilient member deforming such that the resilient member contacts the top surface of the recess from which the ridge downwardly extends when the first plate associated with the recess and the ridge is in a loaded state.
