Adhesiveless decorative floor tile

摘要

A decorative floor tile including at least one decorative layer and a backing layer having an array of resilient annular projections. Each annular projection includes a concave top surface, an outside wall surface, and an inside wall surface. The inside wall surface defines a central, blind passageway area. When the decorative floor tile is installed over an underlying surface, and pressure is applied to the decorative floor tile, a vacuum is created within the blind passageway and the underlying surface. The vacuum increases the amount of frictional drag between the surface covering and the underlying surface, and thus allows the surface covering to remain in place without the need for an adhesive.

1. An adhesiveless decorative floor tile comprising:
at least one resilient Luxury Vinyl Tile decorative layer and a backing layer comprising; an array of resilient walls that define an array of flat regions at least partially bounded by said walls that project outwardly from an outer surface of said backing layer, wherein at least two of said walls intersect so as to define an array of passageways arranged so that when pressure in the form of a variable lateral loading is applied to said decorative layer, a responsive force directed in opposition to said variable lateral loading is formed within said combination of said flat regions and said walls allowing said decorative floor tile to remain in place on a surface in the absence of adhesive.
