Abstract

The present invention is a hardwood flooring board including a middle layer formed from a non-hardwood flooring material and a hardwood material upper layer which is secured to an upper surface of the middle layer that is thick enough to include decorative designs. The middle layer forms between 45% and 75% of the overall material of the board and enables the board to be manufactured to be more dimensionally stable, i.e., wider and longer, than conventional hardwood flooring boards such that the boards can be more uniformly constructed. Also the use of the non-hardwood material in the middle layer greatly increases the dimensional stability and long term performance of the flooring boards, while providing a genuine hardwood appearance to the floor. The board also includes a lower layer that can be formed from either a hardwood material or a non-hardwood material to function as a base for the board. The upper layer is secured to the middle layer by an adhesive that is urged into the openings or cracks in the upper layer during the assembly of the board to prevent the cracks from spreading through the upper layer when the boards are in use.

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application is a continuation of U.S. patent application Ser. No. 11 / 002,856 filed on Nov. 30, 2004, which is a continuation-in-part of U.S. patent application Ser. No. 10 / 863,696, filed on Jun. 8, 2004 which claims priority from U.S. Provisional Patent Application Ser. No. 60 / 563,638, the entirety of which are incorporated herein by reference.FIELD OF THE INVENTION

[0002] The present invention relates to flooring surfaces, more specifically to a flooring surface made of individual flooring boards secured to one another to form the flooring surface. BACKGROUND OF THE INVENTION

[0003] In a large number of commercial and residential buildings, hardwood flooring surfaces are utilized to provide an aesthetically pleasing appearance to the interior of the building. In most instances, the flooring surface is formed from a number of flooring boards or planks engaged with one another to form the flooring surface. These boards are usually f...

Embodiment Construction

[0023] With reference now to the drawing figures in which like reference numerals designate like parts throughout the disclosure, a flooring surface is shown generally at 8 in FIG. 1. The surface is formed over a support surface 9, such as a concrete slab, from a number of flooring boards 10 constructed according the present invention.

[0024] Looking now at FIGS. 2-3, each board 10 is between 0.10 inches and 1.00 inches, and preferably about 0.75 inches in thickness, and includes an upper layer 12, a core or middle layer 14 and a lower layer 16. The upper layer 12 and the lower layer 16 can be attached to opposites sides of the middle layer 14 in any conventional manner, such as by using an adhesive or mechanical fasteners, in conjunction with heat and / or pressure, so as long as the upper layer 12 and lower layer 16 are prevented from delaminating or otherwise becoming detached from the middle layer 14 during the installation and use of the boards 10.

[0025] The upper layer 12 is fo...
