Patent ID: 7487622

Claim:
A modular frame for a system of tiles comprising: a planar member defined by a perimeter having four sides, a top surface and bottom surface; on each side of said perimeter, a flange projection upwardly from the top surface, for containing tiles placed on the planar member; a plurality of downwardly projecting support legs of common length dispersed on the bottom surface in an array pattern; a plurality of connection bosses extending outside the perimeter of the planar member from at least one side of the planar member, for receiving a support leg of a like frame and thereby forming an interlock with the like frame; a filler frame adapted to divide the top surface of the planar member into a predetermined pattern of subdivisions, said filler frame having a first notch for engaging the flange of the planar member and a second notch for engaging the top surface of the planar member, said filler frame having a height that is substantially the same as the height of the flange; a plurality of notches on the inside surface of each flange for engaging the first notch of the filler frame; and a plurality of through-openings dispersed on the planar member for engaging the second notch of the filler frame.
