Stair Tread

Abstract

A stair tread has a generally planar member that is supported by a horizontal surface of a step. The planar member has a top surface, a bottom surface, a back edge, and a leading edge. The leading edge extends beyond a front edge of the step when the stair tread is positioned on the step. A bull nose is formed on the leading edge of the planar member and extends below the horizontal surface of the step. An adhesive layer disposed on the bottom surface of the planar member adheres the stair tread to the top surface of the step. A face plate may adhere to a riser associated with the step and extend behind the stair tread.

1 . A stair tread comprising:
 a generally planar member configured to be supported by a horizontal surface of a step, said planar member having a top surface, a bottom surface, a back edge, and a leading edge that extends beyond a front edge of the step when the stair tread is positioned on the step;   a bull nose formed on the leading edge of the planar member, said bull nose extending below the horizontal surface of the step; and   an adhesive layer on a bottom surface of the planar member for adhering the stair tread to the step.   
     
     
         2 . The stair tread of  claim 1  wherein the bull nose includes a rearwardly facing surface configured to engage a riser of the step when the stair tread is positioned on the step. 
     
     
         3 . The stair tread of  claim 2  wherein the rearwardly facing surface is disposed at an angle. 
     
     
         4 . The stair tread of  claim 1  wherein the back edge of the planar member is configured to engage a riser of a step adjacent to the step on which the stair tread is positioned. 
     
     
         5 . The stair tread of  claim 1  wherein the planar member and bull nose are formed as a unitary member. 
     
     
         6 . The stair tread of  claim 5  wherein the planar member and bull nose are made of a thermoplastic material. 
     
     
         7 . The stair tread of  claim 1  wherein the top surface includes a pattern imitating a natural material. 
     
     
         8 . The stair tread of  claim 7  wherein the pattern comprises a wood grain pattern. 
     
     
         9 . A stair tread assembly comprising:
 a stair tread configured to be installed on a horizontal surface of a step, said stair tread comprising a generally planar member including a bottom surface, a top surface, a back edge, and a leading edge that extends beyond the step when the stair tread is positioned on a step;   a bull nose formed on the leading edge of the planar member of the stair tread and configured to extend below the horizontal surface of the step when the stair tread is positioned on the step, said bull nose including a rearwardly facing surface having a channel formed therein;   a face plate configured to be installed on a riser of the step, said face plate comprising;   a generally planar member having a front surface, a back surface, a top edge, and a bottom edge; and   a protrusion formed on the top edge of the planar member of the face plate, said protrusion configured to engage within the channel formed in the stair tread when the face plate and stair tread are positioned on a step.   
     
     
         10 . The stair tread assembly of  claim 9  further comprising a first adhesive layer on a bottom surface of the planar member of the stair tread for securing the stair tread to the horizontal surface of the step, and a second adhesive layer on a back surface of the face plate for securing the face plate to the riser of the step. 
     
     
         11 . The stair tread assembly of  claim 9  wherein the stair tread and face plate are each unitary members. 
     
     
         12 . The stair tread assembly of  claim 11  wherein the stair tread and face plate are each made of a thermoplastic material. 
     
     
         13 . The stir tread assembly of  claim 9  wherein a top surface of the stair tread include a pattern imitating a natural material. 
     
     
         14 . The stair tread assembly of  claim 13  wherein the pattern comprises a wood grain pattern.
