Abstract: The invention includes a subfloor assembly for supporting a floor surface on a substrate. The subfloor assembly includes a plurality of plate members extending in parallel relation along the substrate, with a space formed between adjacent plate members. A plurality of sleeper members extending longitudinally along the substrate, and are located in the spaces between adjacent plate members. First resilient members are positioned on the upper surface of each of said plate members, and second resilient members are positioned below the lower surface of each of said sleeper members. The floor surface is attached to an upper surface of said sleeper members. The second resilient members are preferably more compressible than the first resilient members. The subfloor assembly also preferable has a plurality of brackets that limit upper movement of the sleeper members but permit downward movement of the sleeper members.

Abstract: The present invention provides a subfloor system for placement over a substrate. The subfloor consists of a base, a resilient pad, an upper member, and brackets. The resilient pad is positioned on the base, preferably within an elongated slot formed in the upper surface of the base. The upper member is operably connected to the top surface of the resilient pad. The upper member has a projection and two shoulders. The brackets have an upper and lower tab and are secured to the base and to the upper member. The lower tab is adapted to fit within the base and the upper tab rests on the corresponding shoulder of the upper member. When under load, the resilient pad compresses thereby causing the upper member to move towards the base. The brackets, however, limit vertical movement of the upper member relative to the base. The invention also includes a method of forming a resilient sports floor employing such a subfloor system.

Abstract: A resilient pad for resiliently supporting a floor on a substrate is disclosed. The resilient pad includes a resilient inner element and an outer element which surrounds the inner element. The outer element is made of a material which is of higher durometer than the inner element, and is lower in profile than the inner element. Preferably the outer element is non-resilient. Under normal loads applied to the floor, the softer inner element contacts the substrate, resulting in desirable floor response characteristics. Under heavy loading, the harder outer element comes into contact with the substrate, thus supporting the floor and preventing damage to the inner element.

Abstract: The invention is a resilient pad for placement under a floor system. The pad is made up of a base and a plurality of pad elements spaced longitudinally apart and attached to the base. At least one of the pad elements has a thickness which is greater than another of the pad elements. Because the pad elements have different thicknesses, the resilient pad provides desirable response and shock-absorption characteristics over a wide range of applied loads. Hence, the resilient pad is especially suitable for use with sports floors and the like.
