Patent ID: 8171691

Claim:
A floor member comprising, a) a first floor member portion having a first polygonal shape with at least two side edges, said first floor member portion having a substrate layer of flexible compressible composite cork sheet material with an upper surface, a top layer for walking upon formed of transparent plastic material provided over the upper surface of the composite cork sheet material and double flexible plastic underlayers provided between the top layer for walking upon and the upper surface of the composite cork sheet material to prevent the upper surface of the composite cork sheet material from dimpling through or telescoping through to the top layer for walking upon, the upper surface of the composite cork sheet material or one of the double flexible plastic underlayers being provided with a cork design pattern or wood design pattern visible through the top layer, said first floor member portion having a first lower surface, b) a second floor member portion of flexible plastic material having a second polygonal shape with at least two side edges, a second upper surface and a second lower surface, c) said first and second floor member portions being laminated together in offset relationship, and wherein the first lower surface of the first floor member portion contacts the second upper surface of the second floor member portion, d) the offset lamination of said first and second floor member portions defining a first offset marginal portion of said first floor member portion and a second offset marginal portion of said second floor member portion, said first marginal portion of said first floor member portion extending beyond at least one of the side edges of said second floor member portion, and said second marginal portion of said second floor member portion extending beyond at least one of the side edges of said first floor member portion, e) said first offset marginal portion having a first marginal lower surface that is part of the first lower surface of said first floor member portion, and said second offset marginal portion having a second marginal upper surface that is a part of the second upper surface of said second floor member portion, at least one of the first marginal lower surface and the second marginal upper surface having an exposed adhesive coating, f) the first and second floor member portions having respective predetermined thicknesses to enable the floor member to have a flexibility that permits the floor member to be bendable to facilitate assembly of the floor member into an assembly of floor members, g) the plastic material of said second floor member portion having a predetermined yieldability to surface irregularities of the floor base upon which the floor member is laid, such that said second floor member portion, when lying in flat contact on the floor base can conform to surface irregularities of the floor base.
