Apparatus for refacing stair step

Abstract

An apparatus for refacing an existing stair step without having to remove the existing step in its entirety or cause destruction to the existing step and surrounding structure includes includes a stair tread, a nosing, a cove moulding, a riser cap, and a shoe moulding. The tread-cap apparatus may be placed over an existing stair step, thereby overcoming the need to remove or destroy the existing stair step as is common with typical stair refinishing processes.

1 . An apparatus for renovating an existing stair step without removing or destroying the stair step, the apparatus comprising:
 a stair tread having a front edge and a back edge;   a nosing connected to a portion of the front edge of the stair tread, wherein the nosing has a top portion and a bottom portion;   a riser cap having a top portion and a bottom portion, wherein the top portion of the riser cap is connected to the nosing;   a cove moulding connected to the bottom portion of the nosing and the top portion of the riser cap; and   a shoe moulding connected to the bottom portion of the riser cap,   
   
   
       2 . The apparatus recited in  claim 1 , further comprising a first substrate layer, wherein the first substrate layer is placed between the existing stair step and the stair tread. 
   
   
       3 . The apparatus recited in  claim 2 , wherein the first substrate layer is a cross-grain veneer. 
   
   
       4 . The apparatus recited in  claim 2 , further comprising a second substrate layer, wherein the second substrate layer is placed between the existing stair step and the first substrate layer. 
   
   
       5 . The apparatus recited in  claim 4 , wherein the second substrate layer is made of formica. 
   
   
       6 . The apparatus recited in  claim 1 , wherein the nosing further comprises a slot joint, wherein the slot joint begins at a back portion of the nosing and extends partially towards a front portion of the nosing. 
   
   
       7 . The apparatus recited in  claim 6 , further comprising a substrate layer placed between the existing stair step and the stair tread, wherein an edge portion of the substrate layer is inserted into the slot joint to add strength to the nosing. 
   
   
       8 . The apparatus recited in  claim 7 , wherein the substrate layer is a cross-grained veneer. 
   
   
       9 . The apparatus recited in  claim 1 , further comprising an adhesion layer placed between the stair tread and the existing stair step. 
   
   
       10 . The apparatus recited in  claim 9 , wherein the adhesion layer is selected from the group consisting of polyethlylene, polyurethane, and a combination of polyethylene and polyurethane. 
   
   
       11 . The apparatus recited in  claim 1 , further comprising a side cap placed adjacent to a side portion of the stair tread and a side portion of the nosing. 
   
   
       12 . The apparatus recited in  claim 1 , wherein the stair tread, the nosing, the riser cap, the cove moulding and the shoe moulding are manufactured as a single apparatus from one material. 
   
   
       13 . The apparatus recited in  claim 1 , wherein the stair tread, the nosing, the riser cap, the cove moulding and the shoe moulding are manufactured as individual separate components. 
   
   
       14 . An apparatus for renovating an existing stair step without removing or destroying the stair step, the apparatus comprising:
 a stair tread having a front edge and a back edge;   a nosing connected to a portion of the front edge of the stair tread, wherein the nosing has a top portion and a bottom portion, wherein the nosing further comprises a slot joint, wherein the slot joint begins at a back portion of the nosing and extends partially towards a front portion of the nosing;   a substrate layer placed between the existing stair step and the stair tread, wherein an edge portion of the substrate layer is inserted into the slot joint to add strength to the nosing;   a riser cap having a top portion and a bottom portion, wherein the top portion of the riser cap is connected to the nosing;   a cove moulding connected to the bottom portion of the nosing and the top portion of the riser cap;   a shoe moulding connected to the bottom portion of the riser cap; and   a side cap placed adjacent to a side portion of the stair tread and a side portion of the nosing.   
   
   
       15 . An apparatus for renovating an existing stair step without removing or destroying the stair step, the apparatus comprising:
 a stair tread having a front edge; and   a riser cap having a top portion and a bottom portion, wherein the top portion of the riser cap is connected to the front edge of the stair tread,   wherein the connected stair tread and riser cap are applied over an existing staiur tread and an existing riser cap, respectively.
