Flooring apparatus for reducing impact energy during a fall

Patent

Description

An apparatus including an impact surface and a plurality of spaced apart stiffening columns extending from an underside of the flooring plate. The columns remain substantially rigid up to a predetermined critical pressure and then buckle as the pressure increases. The columns are at least partially surrounded by a resilient underlayment. Deflection stops may extend from the flooring plate to prevent over-buckling and/or permanent deformation of the stiffening columns. In some examples, the deflections stops may assist the floor in providing a substantially rigid surface at very high pressures.
