Abstract: The subject invention is directed to non-metallic flooring elements having a hooked-tongue and groove locking arrangement. Advantageously, the subject invention allows for horizontal interlocking, with no angled introduction needed. As a result, the same locking arrangement can be used for the sides and the ends of the flooring element. This allows for the use of two tools for manufacturing about the perimeter of the flooring element—one tool for the hooked-tongue element and one tool for the groove.

Abstract: 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.

Abstract: A plank is provided that has opposing first and second ends extending along a width of the plank, opposing first and second longitudinal sides extending along a length of the plank, and opposing top and bottom surfaces. The plank can have a tongue edge at the first end and a groove edge at the second end. The tongue edge can be detachably lockable into the groove edge of an adjacent, identical plank. Surface covering systems having a plurality of the planks connected together are also provided.

Abstract: 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.
