Abstract
A pad for a hardwood floor which has an upper layer of floorboards and a lower subfloor, and a plurality of the pads supporting the subfloor and floorboards in spaced relation above a base, each of the pads including horizontally oriented triangular openings defined by angled legs, to optimize the restoring force of the pads and thereby extend the useful life of the hardwood floor.

A hardwood floor covering a base comprising:
- an upper layer of floorboards;
- a subfloor residing below the upper layer;
- and
- a plurality of resilient pads supporting the subfloor and upper layer in spaced relation above a base, each of the pads including a first horizontal section contacting the subfloor, a second horizontal section contacting the base and a midsection therebetween, the midsection further including a plurality of legs angled vertically with respect to the first and second horizontal sections and defining a plurality of parallel and horizontally extending openings, the openings being uniform and triangular in transverse cross-sectional shape along their entire lengths and the triangular cross-sectional shape being defined by at least one of the first and second horizontal sections.

A pad for a hardwood floor comprising:
- a first section of generally uniform thickness;
- a second section of generally uniform thickness and spaced from the first section;
- and
- a midsection residing between the first and second sections, the midsection further including a first plurality of legs extending parallel between the first and second sections and angled with respect to a vertical plane, and a second plurality of legs also extending parallel between the first and second sections and angled with respect to the vertical plane but perpendicular to the first plurality of legs, the legs defining a plurality of openings which are uniform and triangular in transverse cross-sectional shape along their entire lengths and the triangular cross-sectional shape being defined by at least one of the first and second sections.
