Description

    CROSS-REFERENCE TO RELATED APPLICATIONS
  • This application claims priority from U.S. Patent Application Ser. No. 61/103,642, filed Oct. 8, 2008, which is hereby incorporated by reference in its entirety.
  • FIELD OF THE INVENTION
  • The present invention relates to a flooring panel for a flooring system wherein the flooring panel has a core provided with at least a portion of a locking member, and the core is interposed between opposing first and second decorative surfaces.
  • BACKGROUND OF THE INVENTION
  • Flooring panels, such as laminate flooring panels, include a core and a top decorative surface with a visible design. Each of the flooring panels therefore has only a single visible design. Since most flooring applications require a large number of flooring panels, it is therefore necessary for manufacturers, distributors and sellers to inventory a large number of flooring panels for each type of visible design. Additionally, it is difficult to mix multiple visible designs in a single flooring application, because separate flooring panels, which may or may not be compatible for installation, need to be purchased.
  • It is therefore desirable to provide a flooring panel with more than one decorative surface wherein each of the decorative surfaces has a different visible design so that the amount of inventory can be reduced for each type of visible design. It is further desirable to develop a flooring panel with more than one decorative surface wherein each of the decorative surfaces has a different visible design so that multiple visible designs can easily be mixed to achieve a desired floor design. It is still further desirable to develop a locking member for the aforementioned flooring panel so that the flooring panel can easily be installed with either decorative surface being visible.
  • BRIEF SUMMARY OF THE INVENTION
  • The invention relates to a flooring panel for a flooring system comprising a core interposed between a first decorative surface and a second decorative surface. The core has opposing first and second side surfaces extending substantially perpendicular to the first and second decorative surfaces. The first and second decorative surfaces have different visible designs, and at least the first side surface is provided with at least a portion of a locking member.
  • The invention further relates to a flooring system comprising at least a first and second flooring panel. The first and second flooring panels each have a core interposed between a first decorative surface and a second decorative surface. The core has opposing first and second side surfaces extending substantially perpendicular to the first and second decorative surfaces. The first side surface of the first flooring panel is positioned adjacent to the second side surface of the second flooring panel. The first and second decorative surfaces have different visible designs. A locking member extends between the first side surface of the first flooring panel and the second side surface of the second flooring panel and locks the first flooring panel to the second flooring panel.

  • DETAILED DESCRIPTION OF THE EMBODIMENT(S)
  • FIG. 1 shows a flooring system 1 including first and second flooring panels 2, 3 according to a first embodiment of the invention. As shown in FIG. 1, the flooring system 1 consists of at least two of the first and second flooring panels 2, 3 mounted on a sub-floor 4. In the illustrated embodiment, the first and second flooring panels 2, 3 are identical and each consists of a core 5, a first decorative surface 6, a second decorative surface 7, and a locking member 10. The core 5 is interposed between the first and second decorative surfaces 6, 7. The core 5 may be, for example, a wood laminate core consisting of one or more layers of high density fiberboard or medium density fiberboard. The core 5 has opposing first and second side surfaces 8, 9 that extend substantially perpendicular to the first and second decorative surfaces 6, 7. The first decorative surface 6 opposes the second decorative surface 7 and extends substantially parallel thereto. The first and second decorative surfaces 6, 7 may consist, for example, of a printed and impregnated cellulosic layer having a desired visible design. The visible design of the first decorative surface 6 is different from the visible design of the second decorative surface 7. It will be appreciated by those skilled in the art, however, that the visible design of the first decorative surface 6 and the visible design of the second decorative surface 7 may be the same. Each of the first and second flooring panels 2, 3 are symmetrical about a central axis 15 extending substantially parallel to the first and second decorative surfaces 6, 7 and substantially perpendicular to the first and second side surfaces 8, 9. The flooring panels 1, 2 can be of various shape, for example, rectangular, square, or any other shape.
  • The locking member 10 is formed on the first and second side surfaces 8, 9 of the core 5. The locking member 10 consists of a tongue 11 and a groove 12. The tongue 11 extends from the first side surface 8 of the core 5 substantially from a center thereof. The tongue 11 may be materially formed in one piece with the core 5. The tongue 11 has opposing lateral surfaces provided with indentations 13. The tongue 11 has a mating surface 16 extending substantially perpendicular to the first and second decorative surfaces 6, 7. The mating surface 16 may be beveled to facilitate insertion of the tongue 11 into the groove 12. The groove 12 is formed in the second side surface 9 of the core 5 in a substantial center thereof. The groove 12 has a size and configuration corresponding to the size and configuration of the tongue 11. The groove 12 has an abutment surface 17 extending substantially perpendicular to the first and second decorative surfaces 6, 7. The groove 12 has opposing lateral surfaces provided with projections 14 corresponding to the indentations 13 of the tongue 11. The projections 14 may be materially formed in one piece with the core 5. The tongue 11 and the groove 12 are formed such that when the first side surface 8 of the first flooring panel 2 opposes the second side surface 9 of the second flooring panel 3, the tongue 11 is capable of mating with the groove 12 and locking therewith. Although the tongue 11 is shown and described herein as having the indentations 13 and the groove 12 is shown and described herein as having the projections 14, it will be appreciated by those skilled in the art that alternatively the tongue 11 may be formed to have the projections 14 and the groove 12 may be formed to have the indentations 13. Further, it is not necessary that the number of the projections 14 and the number of the indentations 13 be the same or be limited to two, the number of the projections 14 and the number of the indentations 13 may be varied to achieve a desired result.
  • As shown in FIG. 1, when the first and second flooring panels 2, 3 are mounted on the sub-floor 4, the first and second flooring panels 2, 3 are arranged such that the second decorative surfaces 7 of both of the first and second flooring panels 2, 3 are arranged adjacent to the sub-floor 4. The first side surface 8 of the first flooring panel 2 opposes the second side surface 9 of the second flooring panel 3. The tongue 11 of the first flooring panel 2 is inserted into the groove 12 of the second flooring panel 3 so that the projections 14 engage with the indentations 13 to lock the first flooring panel 2 to the second flooring panel 3. When the first flooring panel 2 is locked to the second flooring panel 3, the first and second flooring panels 2, 3 are prevented from moving in a direction substantially perpendicular to the first and second decorative surfaces 6, 7 and in a direction substantially perpendicular to the first and second side surfaces 8, 9. It will be appreciated by those skilled in the art, however, that the first and second flooring panels 2, 3 may also be arranged such that the first decorative surfaces 6 of both of the first and second flooring panels 2, 3 are arranged adjacent to the sub-floor 4. Thus, because the first and second flooring panels 2, 3 are reversible, the visible design of the first decorative surface 6 or the visible design of the second decorative surface 7 may be made visible depending on the desired floor design.
  • FIG. 2 shows a second example of the flooring system 1 including the first and second flooring panels 2, 3 according to the first embodiment of the invention. As shown in FIG. 2, when the first and second flooring panels 2, 3 are mounted on the sub-floor 4, the first and second flooring panels 2, 3 are arranged such that the first decorative surface 6 of the first flooring panel 2 and the second decorative surface 7 of the second flooring panel 3 are arranged adjacent to the sub-floor 4. The first side surface 8 of the first flooring panel 2 opposes the second side surface 9 of the second flooring panel 3. The tongue 11 of the first flooring panel 2 is inserted into the groove 12 of the second flooring panel 3 so that the projections 14 engage with the indentations 13 to lock the first flooring panel 2 to the second flooring panel 3. When the first flooring panel 2 is locked to the second flooring panel 3, the first and second flooring panels 2, 3 are prevented from moving in a direction substantially perpendicular to the first and second decorative surfaces 6, 7 and in a direction substantially perpendicular to the first and second side surfaces 8, 9. Thus, because the first and second flooring panels 2, 3 are not only reversible, but also the locking member 10 is configured to be reversible, the visible design of the first decorative surface 6 and the visible design of the second decorative surface 7 may be caused to alternate depending on the desired floor design.
  • FIG. 3 shows a first alternate embodiment of the locking member 10 of the first and second flooring panels 2, 3 according to the first embodiment of the invention. As shown in FIG. 3, the locking member 10 consists of the tongue 11 and the groove 12. The mating surface 16 of the tongue 11 is provided with a hook material 20.
