Stair nosing

Abstract

A prefabricated stair nose for floor installations on stairs wherein the present invention is manufactured from wood or other suitable material. The stair nose of the present invention includes four embodiments wherein all four embodiments include a lower inset formation that is configured to be placed on an edge of a stair tread. The body of the present invention further includes an upper inset formation wherein the upper inset formation is configured to engage a portion of a wood floor plank. Two embodiments of the present invention further include a groove inset formation that is operable to mateable couple with a tongue formation of a wood floor plank. The body of the stair nosing of the present invention is provided with both an arcuate shaped front surface and a square shaped front surface.

What is claimed is: 
     
         1 . A stair nosing configured to be placed on a stair tread during installation of a wood floor wherein the stair nosing comprises:
 a body, said body having a first end and a second end, said body having an upper edge and a lower edge, said body having a front surface, said body further having an upper inset formed therein, said upper inset being formed proximate said second end and said upper edge.   
     
     
         2 . The stair nosing as recited in  claim 1 , wherein said body further include a lower inset, said lower inset being formed proximate said second and said lower edge. 
     
     
         3 . The stair nosing as recited in  claim 1 , wherein said front edge is perpendicular to said lower and said upper edge so as to form a flat front edge. 
     
     
         4 . The stair nosing as recited in  claim 2 , wherein said lower inset has a depth that ranges from four millimeters to nineteen millimeters. 
     
     
         5 . The stair nosing as recited in  claim 4 , wherein said body further includes a groove inset, said groove inset being formed in a forward edge surface of said upper inset. 
     
     
         6 . The stair nosing as recited in  claim 5 , wherein said lower inset has a height that ranges from three to twelve millimeters. 
     
     
         7 . The stair nosing as recited in  claim 6 , wherein said groove inset has a height ranging from three to twelve millimeters. 
     
     
         8 . The stair nosing as recited in  claim 7 , wherein said upper inset has a depth that ranges from four to fifty millimeters. 
     
     
         9 . The stair nosing as recited in  claim 8 , wherein said upper inset has a height ranging from four to nineteen millimeters. 
     
     
         10 . The stair nosing as recited in  claim 9 , wherein said body has a depth ranging from nine to fifty millimeters. 
     
     
         11 . The stair nosing as recited in  claim 10 , wherein said body has a height that ranges from twelve to fifty millimeters. 
     
     
         12 . The stair nosing as recited in  claim 11 , wherein said front edge is contiguously formed with said upper edge and said lower edge being intermediate thereto, said front edge being arcuate in form.
