Surface coverings, such as floor coverings, with an interlocking design are described. Methods of making the surface coverings are further described. A plank including a resilient composite sheet having four sides, an upper surface, a lower surface, and an overall thickness, and said composite sheet including at least one base layer, wherein said at least one base layer including at least one polymeric material and at least one filler, wherein opposite sides of the composite sheet include a first tongue on a first side and a first groove on the opposite second side, wherein the first tongue and first groove have complementary shape to each other to be interlockingly engageable with a corresponding groove or tongue on an adjacent floor plank.

Floor covering with interlocking design

Surface coverings, such as floor coverings, with an interlocking design are described. Methods of making the surface coverings are further described. A plank including a resilient composite sheet having four sides, an upper surface, a lower surface, and an overall thickness, and said composite sheet comprising at least one base layer, wherein said at least one base layer comprising at least one polymeric material and at least one filler, wherein opposite sides of the composite sheet comprise a first tongue on a first side and a first groove on the opposite second side, wherein the first tongue and first groove have complementary shape to each other to be interlockingly engageable with a corresponding groove or tongue on an adjacent floor plank.

Surface coverings, such as floor coverings, with an interlocking design are described. Methods of making the surface coverings are further described.

A plank, and system and method for joining surface-covering planks, which includes a disengageable connector(s) for detachably connecting multiple planks simultaneously are described. A plank can include a tongue-profiled edge and an opposite rib-profiled edge, and a disengageable connector can have a groove that can be mated with the tongue on one side edge of the plank, and also has a rib-receiving portion that alternatively can be mated with a downward extending rib on the opposite side edge of the plank. The plank can have a variety of designs on the other edges of the plank.

Connecting system for surface coverings

A system and method for joining floor planks includes two or more planks wherein each plank includes a tongue, a groove, and optionally a shoulder, and optionally a protruding lip, that provide a mechanism for connecting two or more planks together. The tongue can be on the opposing side of each plank from the groove. The groove can be defined between a first flange extending along a first edge of the plank and from one side of the plank, and a second flange extending distally beyond a distal edge of the first flange from the first edge of the plank and from a second side of the plank opposite from the first side. The tongue can be S-shaped to form an interlocking relationship with the groove.

A surface covering system is described which involves a series of interconnected tiles having a spline system located between the tiles to simulate the appearance of grout. Each tile has on its sides, at least one tongue section and at least two groove sections wherein the tongue section of one tile interconnects with the groove section of a second tile and further forms a gap at least at the upper surface between the two tiles. A first spline, having two tongue sections for interconnecting with the groove section(s) of at least one tile, is inserted between a series of tiles. A second spline capable of fitting into the gap formed between two or more tiles, which are interconnected at a tongue of a first tile and a groove of a second tile is further used. Methods of installing the surface covering system of the invention are further described.
