Abstract

Abstract A modular floor tile has a two piece construction including a top member and a support member. The top member is made of a relatively hard material that is resistant to scuffing and which accepts paints. The support member is made of a resilient, impact-absorbing material and is secured to the underside of the top member. The material of the support member is selected to give the desired impact-absorbing characteristics. In a preferred embodiment, a plurality of support nodes extend downward from a bottom surface of the support member. The support nodes are spaced from one another so as to define an air circulation space between the bottom surface of the support member and the underlying support surface. The modular floor tiles also include interlocking members for interlocking adjacent tiles with one another.
