Patent ID: 8458974

Claim:
A component of a flooring system comprising a tray substrate comprising a tray substrate surface which is an upward facing horizontal surface having a tray substrate surface perimeter, a tray substrate bottom with a padding attached to the tray substrate bottom, a plurality of tray substrate edges defining an outside perimeter of the tray substrate, the tray substrate edges having a plurality of radial arms; each radial arm extending horizontally in a radial direction from a geometric center of the radial arms; with each radial arm having at least one adjacent radial arm and each radial arm and the adjacent radial arm are separated by a radial angle, at least two radial arms of the plurality of radial arms protrude from the tray side in the radial direction measured from the geometric center of the radial arms at least two stops located on the outside perimeter between at least one radial arm and at least one adjacent radial arm adjacent to the at least one radial arm wherein one of the at least two stops is located between the at least one radial arm and the midpoint of the outside perimeter between the at least one radial arm and the at least one adjacent radial arm adjacent to the at least one radial arm and another of the at least two stops is located between the midpoint of the outside perimeter between the at least one radial arm and the at least one adjacent radial arm adjacent to the at least one radial arm and the at least one adjacent radial arm adjacent to the at least one radial arm.
