Two-ply flooring having a cross-grain bottom ply

Abstract

A two-ply flooring plank is disclosed having two layers or “plies” with a bottom layer having a grain that runs generally transverse to a top layer (i.e., “cross-ply”) to provide dimensional stability to the plank. The bottom layer includes a number of strips secured to the bottom of the top layer. The bottom layer strips are also placed with gaps between the individual strips of the second layer to allow flexibility of the flooring plank, which allows the flooring to more easily conform to irregularities in a subfloor upon which the flooring plank is mounted.

What is claimed is:  
     
         1 . A flooring plank, comprising: a first layer including a first plurality of strips that are secured together, each of the first plurality of strips having a grain extending generally in a longitudinal direction of the plank; and a second layer secured to one face of the first layer, the second layer including a second plurality of spaced strips each having a grain extending generally transversely to the longitudinal direction of the plank.  
     
     
         2 . The flooring plank according to  claim 1 , wherein each of the strips is composed of at least one of bamboo and wood.  
     
     
         3 . The flooring plank according to  claim 1 , wherein another face of the first layer is coated with at least one coat of acrylic urethane.  
     
     
         4 . The flooring plank according to  claim 1 , further including at least one tongue configured to mate with at least one groove of another flooring plank.  
     
     
         5 . The flooring plank according to  claim 1 , further including at least one groove configured to receive at least one tongue of another flooring plank.  
     
     
         6 . The flooring plank according to  claim 1 , further including at least one coat of acrylic urethane disposed on multiple surfaces thereof.  
     
     
         7 . The flooring plank according to  claim 1 , having at least one application of aluminum oxide disposed thereon.  
     
     
         8 . A flooring plank, comprising: a first layer comprising a first plurality of bamboo strips secured together in side-by-side relation, wherein each strip has a grain extending generally parallel to a longitudinal dimension of the plank; and a second layer secured to one face of the first layer, wherein the second layer includes a second plurality of strips each having a grain extending generally transverse to the longitudinal dimension of the plank.  
     
     
         9 . The flooring plank of  claim 8 , wherein each of the second plurality of strips is made of one of bamboo and wood.  
     
     
         10 . The flooring plank of  claim 9 , wherein the grain of each strip of the second plurality is disposed substantially perpendicular to the longitudinal dimension.  
     
     
         11 . The flooring plank of  claim 10 , further including a coat of acrylic urethane disposed on another face of the first layer.  
     
     
         12 . The flooring plank of  claim 11 , further including a tongue disposed at a first side of the plank and a groove disposed at a second side of the plank.
