Trim molding system and apparatus

Abstract

A trim molding system including trim pieces having a tab and corresponding keyway system. The tab fits into the keyway. Trim boards having keyways are configured to be joined to a corner cap having tabs to provide a trim system that is suitable for use with bullnose corner bead. Trim boards having are configured to be spliced using a splice tab that both joins and aligns the trim boards. Trim boards having keyways are configured to be joined at a corner using an angled corner tab that both joins and aligns the trim boards, and conforms to a corner angle of a surface such as a wall.

1 . A trim molding system comprising: 
 a first trim piece including a front, a back, a top, and a bottom, and having a first keyway formed in the first trim piece, the first keyway having an opening on a side of the first trim piece;    a second trim piece including a front, a back, a top, and a bottom, and having a second keyway formed in the second trim piece, the second keyway having an opening on a side of the second trim piece; and    a corner cap having a top, a bottom, a front, a back, a first side, and a second side, and having a first tab extending from the first side and a second tab extending from the second side;    wherein the first tab is configured to fit into the first keyway of the first trim piece and the second tab is configured to fit into the second keyway of the second trim piece such that the first and second trim pieces are joined with the corner cap, and wherein the first trim piece, the second trim piece, and the corner cap each have a matching trim profile that is substantially continuous when the first trim piece and the second trim piece are joined to the corner cap.    
   
   
       2 . The trim molding system of  claim 1 , wherein the first tab and the second tab are formed integrally with the corner cap.  
   
   
       3 . The trim molding system of  claim 1 , wherein the first tab and the second tab are formed separately from the corner cap.  
   
   
       4 . The trim molding system of  claim 3 , wherein the corner cap further comprises a first corner cap keyway formed into the first side of the corner cap and a second corner cap keyway formed into the second side of the corner cap.  
   
   
       5 . The trim molding system of  claim 4 , wherein, when the first trim piece, the second trim piece, and the corner cap are joined, the first tab is inserted into the first corner cap keyway and the second tab is inserted into the second corner cap keyway.  
   
   
       6 . The trim molding system of  claim 1 , wherein the first trim piece, the second trim piece, and the corner cap are each formed of extruded plastic.  
   
   
       7 . A trim molding system comprising: 
 a first trim piece including a front, a back, a top, and a bottom, and having a first keyway formed in the first trim piece, the first keyway having an opening on a side of the first trim piece;    a second trim piece including a front, a back, a top, and a bottom, and having a second keyway formed in the second trim piece, the second keyway having an opening on a side of the second trim piece; and    a splice tab configured to fit into the first keyway and the second keyway, such that, when assembled, the first trim piece and second trim piece are spliced together; and    wherein the first trim piece and the second trim piece each have a matching trim profile that is aligned so as to be substantially continuous when the first trim piece and the second trim piece are spliced using the splice tab.    
   
   
       8 . The trim molding system of  claim 7 , wherein the first trim piece, the second trim piece, and the splice tab are each formed of extruded plastic.  
   
   
       9 . A trim molding system comprising: 
 a first trim piece including a front, a back, a top, and a bottom, and having a first keyway formed in the first trim piece, the first keyway having an opening on a side of the first trim piece;    a second trim piece including a front, a back, a top, and a bottom, and having a second keyway formed in the second trim piece, the second keyway having an opening on a side of the second trim piece; and    an angled corner tab configured to fit into the first keyway and the second keyway, such that, when assembled, the first trim piece and second trim piece meet at a joint angle defined by the angled corner tab.    
   
   
       10 . The trim molding system of  claim 9 , wherein the first trim piece, the second trim piece, and the angled corner tab are each formed of extruded plastic.  
   
   
       11 . The trim molding system of  claim 9 , wherein the angled corner tab, when inserted into the first trim piece and the second trim piece, aligns the top of first trim piece with the top of the second trim piece.  
   
   
       12 . A bullnose corner molding cap, comprising: 
 a corner cap having a curved portion configured to conform to a bullnose corner of a wall, and having first and second ends;    wherein the ends each include a keyway configured to accept a connecting means, the connecting means being configured to attach the first end to a first trim piece and the second end to a second trim piece; and    wherein the keyway and the connecting means cooperate to achieve a matching trim profile for the corner cap, first trim piece, and second trim piece when assembled together.
