Abstract: A resilient sports floor comprising a top layer, which is designed to be a coherent sheet consisting of boards. In each board recesses are provided in the shape of mutually parallel grooves along the entire length of the board, in which grooves strips of a springy resilient material, e.g. a natural or synthetic rubber material or a porous, springy plastic material, are inserted. The thickness of strips is larger than the depth of grooves, so that the strips project below the underside of layer with their lower portion. The floor is provided with the free surface of strips directly against a rigid sub-floor. In case of extremely high loads strips will be pressed into grooves, so that the strips are relieved due to the fact that the floor is in direct contact with the sub-floor with its underside.
