US Patent 7883425 Flooring system

A floor system for simulating a natural environment, such as snow, is disclosed. The system includes a confinement member that holds an aggregate. The confinement member may be positioned between a pair of disturbing agent layers comprising meshes that contact the confinement member at a plurality of discrete points. Force applied to the floor system by a user walking across the system results in force being communicated to the confinement member through the disturbing agent layers through the plurality of discrete contact points. The force applied at each of the discrete contact points causes portions of the aggregate proximate to the contact points to shift, resulting in vibrations and sounds that simulate the sound and feel of walking on snow. Additional layers for support, durability, and comfort may also be included in the floor system.
