US Patent 7958681 Modular floor tile with nonslip insert system

The principles described herein provide floor tiles and modular floors. The floor tiles include inserts that increase traction. The inserts may be removable and protrude from a top surface of the floor tiles. The tiles may include a locking system that allows adjacent tiles to interlock, while also permitting a predetermined amount of lateral sliding relative to one another. The modular tiles may be injection molded and the inserts may comprise an elastomer. The floor tiles may also provide four layers of traction, providing more sure footing than previous flooring systems.
