Definitions

  • 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.
  • 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.
  • 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.
  • 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.
