Abstract
Description
- This application is a continuation-in-part of U.S. patent application Ser. No. 10/863,696 for an Improved Hardwood Flooring Board filed on Jun. 8, 2004, that claims priority from U.S. Provisional Patent Application Ser. No. 60/563,638, filed on Apr. 20, 2004, the entirety of which are incorporated herein by reference.
- 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.
- 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 formed entirely of the desired hardwood, with each board being formed into the desired shape to facilitate the use of the boards to form the flooring surface.
- However, while these hardwood flooring surfaces provide the desired appearance to the interior of the building, the natural characteristics of traditional solid wood flooring often create challenges during installation and can develop later effecting the long term performance of the floor.
- To reduce these problems, a number of different types of flooring boards have been developed that are formed from non-hardwood materials that give the appearance of a hardwood. While these boards are faster to install and can be less expensive, the quality of the hardwood appearance is often unsatisfactory, and long term performance is poor, as normal wear and tear can often damage the hardwood-appearing surface of the boards, exposing the non-hardwood material forming the board.
- Therefore, it is desirable to develop a flooring board that is made of wood, yet is easy to install with a special profile and construction that insures long term performance. Further, the board should be able to be maintained in a manner similar to that of a hardwood surface and offer all the aesthetic features of a traditional solid wood floor.
- Furthermore, with regard to the veneer layers applied to flooring boards of this type, the veneer layers are constructed from sheets of a hardwood material that are cut in a known manner to form the thin veneers from the hardwood material. In this process, the veneer is usually formed with cracks or gaps in one surface of the veneer, with the other surface being a smooth surface that forms the exposed surface of the flooring board. While these cracks initially do not mar the appearance of the veneer after it is used to form the flooring board, due to fluctuating humidity levels after installation, the cracks can propagate completely through the veneer layer and can break the smooth surface of the veneer, detrimentally effecting the appearance of the hardwood flooring board.
- Therefore, it is also desirable to develop a hardwood flooring board in which the cracks initially present in any veneer layer used to form the exposed, aesthetically pleasing surface of the flooring board are treated to prevent the cracks from propagating through the veneer layer and affecting the overall appearance of the board.
- Also, in order to enhance the appearance of the flooring board and the flooring surface formed by the board, certain decorative features (i.e., a beveled edge, scraping, or embossing) can be added to the hardwood decorative surfaces of the boards during the production and milling process. However, due to the fact that traditional solid hardwood boards need to be sanded on the job site after installation and prior to finishing, any decorative enhancement that was added to the hardwood surface during the production and milling process would be eliminated or significantly altered during this sanding process.
- Thus, it is further desirable to develop a laminate hardwood flooring board that has the ability to incorporate designs on the exposed surface of the board in order to enhance the appearance of the board in manner that would not be eliminated or altered after installation.
- According to a primary aspect of the present invention, an improved hardwood flooring is constructed with upper and lower layers formed of a conventional flooring material and a central or middle layer formed of an alternative non-hardwood flooring material. The board includes a hardwood layer forming the upper layer of the board to give the board the appearance of a conventional hardwood flooring surface when the boards are assembled to form the flooring surface. This enables the boards to be sanded when damaged similarly to a hardwood only board in order to maintain the hardwood appearance of the board.
- However, the use of the alternative flooring material as the middle layer or core of the board greatly increases the dimensional stability of the board. In addition, the raw material cost for the non-hardwood material forming the middle layer costs less than that of the hardwood forming the upper layer. Further, the types of non-hardwood materials that can be used to form the middle layer can be chosen to enhance various properties of the board, such as the dimensional stability, longer average board length and a specially milled connection between each board that significantly minimizes any future visible contraction of each board.
- According to another aspect of the present invention, the upper layer or veneer layer of the board is secured to the middle layer by a suitable adhesive in a process which urges the adhesive into the cracks present on an inner surface of the veneer layer. By urging the adhesive into the cracks, the adhesive effectively prevents the spread or propagation of the cracks in the veneer layer such that these cracks will not detrimentally affect the appearance of the veneer layer by spreading completely through the veneer layer due to any changes in the environmental conditions surrounding the boards.
- According to still another aspect of the present invention, the high-strength construction enables the board to be sanded and precisely milled after it is formed, and prior to installation, such that once the boards is installed they require only a light screening (i.e., sanding with 120 grit sandpaper) that lightly abrades the surface of the board so that the wood readily accepts a finish. Also, because the board does not require significant sanding after installation, the board may be formed with a wide range of decorative features (i.e., a beveled edge, scraping, or embossing) that enhance the appearance of the boards and the resulting flooring surface formed by the boards.
- Other aspects, features and advantages of the present invention will be made apparent from the following detailed description taken together with the drawing and figure.
- The drawings illustrate the best most currently contemplated of practicing the present invention.
- In the drawings:
-
FIG. 1 is an isometric view of a flooring surface constructed using boards formed according to the present invention; -
FIG. 2 is an isometric view of a flooring board constructed according to the present invention; -
FIG. 3 is a cross-sectional view along line 3-3 ofFIG. 2 ; -
FIGS. 4A-4B are partially broken away cross-sectional views of the boards ofFIG. 3 in connected and disconnected configurations; -
FIGS. 5A-5D are partially broken away cross-sectional views illustrating the connection of the boards ofFIGS. 4A-4B ; and -
FIG. 6 is a partially broken away cross-sectional view of a flooring board having a veneer surface secured to the board using the adhesive and method of the present invention. - 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 offlooring boards 10 constructed according the present invention. - Looking now at
FIGS. 2-3 , eachboard 10 is between 0.10 inches and 1.00 inches, and preferably about 0.75 inches in thickness, and includes anupper layer 12, a core ormiddle layer 14 and alower layer 16. Theupper layer 12 and thelower layer 16 can be attached to opposites sides of themiddle 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 theupper layer 12 andlower layer 16 are prevented from delaminating or otherwise becoming detached from themiddle layer 14 during the installation and use of theboards 10. - The
upper layer 12 is formed of a conventional hardwood material in order to provide the desired aesthetic appearance to the flooring surface 8 constructed using theboards 10. Any particular hardwood material can be used forupper layer 12, depending upon the desired appearance for the flooring surface 8. Theupper layer 12 has a thickness of between about two (2) mm and about five (5) mm. This allows theupper layer 12 to be sanded approximately 3-5 times before thelayer 12 is worn completely through. Thus, any gouging, scratching or refinishing of theupper layer 12 can be done similarly to a conventional hardwood flooring board without exposing themiddle layer 14, as occurs with the prior art engineered non-hardwood flooring boards. Also, due to the use of a hardwood material to form theupper layer 12, theboard 10 can have a face grade from the National Oak Flooring Manufacturers Association similar to the boards formed entirely of the hardwood. - The
lower layer 16 can also be formed from a hardwood material similar to theupper layer 12, or can be formed from a non-hardwood material that has certain selected properties, e.g., water resistance or rigidity, as a base for theboard 10. The material forming thelower layer 16 is capable of being secured to the support surface 9 by any suitable means, such as an adhesive, when theboards 10 are attached “in flex,” or a mechanical fastener, e.g., a nail or screw, to hold theboards 10 thereon to form the flooring surface 8. Thelower layer 16 also has a thickness comparable to theupper layer 12, preferably between about two (2) mm and about five (5) mm. - The
middle layer 14 is formed of an alternative, non-hardwood flooring material that provides a stable core for theboard 10. The non-hardwood material used in themiddle layer 14 can be any suitable generally rigid and non-compressible material, but is preferably a material such as High Density Fiber Board, Medium Density Fiber Board, plywood, chipboard, Orientated Strand Board, a cheaper wood or wood composite material, or the like, in comparison to the materials utilized to form theupper layer 12 and thelower layer 16. This non-hardwood material can be selected and used to form themiddle layer 14 to createboards 10 that are more dimensionally stable such as by orienting the non-hardwood material in a direction perpendicular to the length of theboard 10 and the grain of the hardwood forming theupper layer 12. This enables theboards 10 to be made longer and wider than conventional flooring boards which results infewer boards 10 being required to form the flooring surface 8. Also, the non-hardwood material forming themiddle layer 14 can be formed or milled very precisely prior to assembly into theboard 10, which results inuniform boards 10 with tight tolerances than can easily by engaged with one another to form the flooring surface 8. - To accomplish this, the
middle layer 14 is preferably formed to have a thickness of between about six (6) mm and fifteen (15) mm. Thus, themiddle layer 14 forms between about 40% and about 75% of the total material of theboard 10, more preferably between 45% and 65% of the total board material, and most preferably about 55% of the total board material. - In a particularly preferred embodiment, the
upper layer 12 andmiddle layer 14 are secured to one another, with or without thebottom layer 16, in a process where themiddle layer 14 andupper layer 12 are adhered to one another utilizing asuitable adhesive 100, as best shown inFIG. 6 . The adhesive 100 is spread on either theupper layer 12 ormiddle layer 14, with theupper layer 12 andmiddle layer 14 subsequently being pressed together in a known manner. During the compression of theupper layer 12 and themiddle layer 14, the adhesive 100 is cured, such as by heating, UV light, or by mixing of a catalyst into the adhesive prior to application to thelayers layers board 10. Also, if abottom layer 16 is present, thebottom layer 16 can be secured to themiddle layer 14 in the same manner as theupper layer 12, and at the same time as theupper layer 12, or in a completely different manner subsequent to the compression of theupper layer 12 to themiddle layer 14. - Prior to the adhesive completely curing, the adhesive 100 is forced by the compression of the
upper layer 12 andmiddle layer 14 against one another into gaps orcracks 102 present in alower surface 104 of theupper layer 12 in order to more securely adhere theupper layer 12 to themiddle layer 14. The presence of the adhesive 100 in thecracks 102 also serves to prevent the spread or propagation of thecracks 102 from thelower surface 104 through the entireupper layer 12. As such, thecracks 102 will not detrimentally affect the appearance of the exposedupper surface 106 of theupper layer 12. - To enhance the direction of the adhesive 100 into the
cracks 102 during compression, themiddle layer 14 is formed of a non-oriented fiberboard, in a preferred embodiment that prevents the adhesive 100 from being compressed or flowing into the board forming themiddle layer 14, consequently urging the adhesive 100 upwardly into thecracks 102. More preferably, this non-oriented fiberboard has a high density at least long the side positioned adjacent theupper layer 12, i.e., greater than 790 kg/m3, and preferably greater than 850 kg/m3, to enable themiddle layer 14 to more easily urge the adhesive 100 into thecracks 102 in theupper layer 12. To further facilitate the adhesive 100 flowing into thecracks 102, an adhesive having a viscosity of between twenty-five (25) poise and forty (40) poise is utilized, with an adhesive having a viscosity of about thirty (30) poise being especially preferred. In a particularly preferred embodiment for the adhesive 100, the adhesive 100 takes the form of a urea formaldehyde resin that is catalyst curable, such as the urea formaldehyde resin sold under the trade name SYNTEKO 1203 by Casco Products AB of Stockholm, Sweden. - The compression force utilized to secure the
upper layer 12 andmiddle layer 14 to one another must be high enough to direct the adhesive 100 into thecracks 102 without damaging theupper surface 106 of theupper layer 12. Preferably, this force exerted on thelayers cracks 102 within theupper layer 12. The elevated pressure applied to thelayers middle layer 14 to urge the adhesive 100 into theupper layer 12 while also forming a secure bond between theupper layer 12 and amiddle layer 14. - Looking now at
FIGS. 3-5D in order to enable theboards 10 to be secured to one another to form the flooring surface 8, themiddle layer 14 also includes atongue 18 and agroove 20 positioned on and extending along opposite sides of theboard 10. Thetongue 18 is preferably formed integrally with themiddle layer 14, but may be formed of a separate, more rigid or more flexible material that is secured to theboard 10, if desired. Thetongue 18 can have any suitable shape but preferably has abase portion 21 extending outwardly from themiddle layer 14 that has a rounded end 22 disposed opposite themiddle layer 14. A notch orrecess 24 is formed on one side of thebase portion 21 adjacent theupper layer 12 to facilitate the engagement of thetongue 18 within thegroove 20 and to allow a certain amount of expansion of thetongue 18 due to the changing moisture content of theboard 10. - The
groove 20 is shaped to be complimentary to thetongue 18 and preferably defines aninterior space 28 slightly greater than the size of thetongue 18 to accommodate the normal expansion and contraction of thetongue 18 based on the changing moisture content of theboard 10. Thetongue 18 can be secured within thegroove 20 simply by using a friction fit between them, or an adhesive (not shown) or other suitable means to permanently hold thetongue 18 in engagement with thegroove 20. Thegroove 20 can be milled out of themiddle layer 14 during the formation of themiddle layer 14, similarly to thetongue 18. - The side of the
board 10 including either thetongue 18 or thegroove 20 can be formed such that theupper layer 12 extends outwardly further than thelower layer 16 to enable theboards 10 to be joined to form a surface 8 with a minimum of space between theupper layers 12 onadjacent boards 10. - In one particularly preferred embodiment shown best in FIGS. 3, 4A-4B and 5A-5D, the
groove 20 includes one of a connectingrib 26 or connectingnotch 28 integrally formed therein. Therib 26 or notch 28 is engageable with anopposed rib 26 or notch 28 formed on thetongue 18. The engagement of therib 26 with thenotch 28 secures thetongue 18 in engagement with thegroove 20 without using any materials other than theboards 10 themselves, thus reducing the complexity of forming the surface 8 using theboards 10. To properly engage thenotch 28 with therib 26, thetongue 18 is formed with a recessedportion 30 that enables thetongue 18 and notch 28 to be inserted beneath therib 26 and then engaged with one another to secure theboards 10 to each other as illustrated inFIGS. 5A-5D . The engagement of therib 26 with thenotch 28 maintains the positioning of theadjacent boards 10 with one another, such that theboards 10 present a continuous flooring surface 8 as theindividual boards 10 take on and lose moisture due to the changing environmental conditions. - Also, in order to enable the
boards 10 to be more easily attached to the support surface, thelower layer 16 may include one ormore recesses 32 within which an adhesive or other fastening means to be utilized can be positioned to enable theboard 10 to be positioned flush on the support surface 9 when secured to the support surface 9. In situations where mechanical fasteners (not shown) such as nails or screws are used, the fastener on occasion creates splinters when breaking through thebottom layer 16, therecesses 32 is designated to facilitate these splinters. More particularly, therecesses 32 enable theboard 10, and specifically thelower layer 16, to flex under the force of the fastener being engaged with theboard 10 and the support surface 9. - As stated previously, the construction of the
board 10 allows it to be precisely sanded and milled to form highlyuniform boards 10, such that thetongue 18 and thegroove 20 can be very accurately formed to ensure the proper engagement of theboards 10 with one another when forming a flooring surface 8. This also allows theboard 10 to be formed with various decorative features on the exposed surfaces of theboard 10. Virtually any desired decorative design or feature can be formed on theboard 10, and more particularly on theupper surface 106 of theupper layer 12, to enhance the appearance of thefinished board 10. For example, as best shown inFIG. 3 , theboard 10 includes a pair ofbevels 200 formed along each longitudinal side 202 of theupper surface 14. However, thebevels 200 can be formed along each edge of the upper layer, if desired. Thebevels 200 are preferably formed at a forty-five degree (45°) angle with regard to theupper surface 106, but can be formed to have any desired angle or slope, and are formed on theboard 10 in any conventional manner, such as by contacting the sides 202 of theupper layer 14 with a grinding wheel or other suitable device. - The
bevels 200 are formed on theupper surface 106 of theupper layer 12 after theboard 10 has been sanded and milled into the appropriate shape, so that theboard 10 is ready to be installed without any further sanding. Theboards 10, due to their precise and uniform construction, only need to be lightly screened after installation in order to promote the penetration of the selected stain (not shown) into theboards 10. Thus, thebevels 200 remain clear and distinct after installation of theboards 10. - Various alternatives are contemplated as being within the scope of the following claims, particularly pointing out and distinctly claiming a subject matter regarded as the invention.
