Crown molding with improved mounting surfaces

Abstract

A crown molding unit for engagement with a ceiling surface and an adjacent wall surface of a room has a first surface positioned for flush contact with a ceiling surface and simultaneously, a second surface positioned for flush contact with a wall surface. Each of the first and the second surfaces provide a plurality of side-by-side parallel longitudinal grooves and a plurality of side-by-side parallel lateral grooves, the lateral grooves lie orthogonal to the longitudinal grooves and converge to a depression in the apparatus.

1 . A crown molding apparatus for engagement with a ceiling surface and an adjacent wall surface, the apparatus comprising: an integral unit having a length establishing a longitudinal direction of the apparatus, lateral directions of the apparatus defined as orthogonal to the longitudinal direction; the unit further having a first surface for contact with the ceiling surface; the first surface interrupted by a plurality of longitudinally directed first grooves and a plurality of laterally directed second grooves; the laterally directed second grooves each providing a uniformly varying groove width and a depth greater then the first grooves.  
   
   
       2 . The apparatus of  claim 1  wherein the uniform variance of the second grooves converges toward an outside edge of the apparatus.  
   
   
       3 . The apparatus of  claim 2  wherein each of the second grooves provides a depression adjacent the outside edge.  
   
   
       4 . A crown molding apparatus for engagement with a ceiling surface and an adjacent wall surface, the apparatus comprising: an integral unit having a length establishing a longitudinal direction of the apparatus, lateral directions of the apparatus defined as orthogonal to the longitudinal direction; the unit further having a second surface for contact with the wall surface; the second surface interrupted by a plurality of longitudinally directed first grooves and a plurality of laterally directed second grooves; the laterally directed second grooves each providing a uniformly varying groove width and a depth greater then the first grooves.  
   
   
       5 . The apparatus of  claim 4  wherein the uniform variance of the second grooves converges toward an outside edge of the apparatus.  
   
   
       6 . The apparatus of  claim 5  wherein each of the second grooves provides a depression adjacent the outside edge.  
   
   
       7 . A crown molding apparatus for engagement with a ceiling surface and an adjacent wall surface, the apparatus comprising: an integral unit having a length establishing a longitudinal direction of the apparatus, lateral directions of the apparatus defined as orthogonal to the longitudinal direction; the unit further having a first surface for contact with the ceiling surface and a second surface for contact with the wall surface; the each of the first and second surfaces interrupted by a plurality of longitudinally directed first grooves and a plurality of laterally directed second grooves; the laterally directed second grooves each providing a uniformly varying groove width and a depth greater then the first grooves.  
   
   
       8 . The apparatus of  claim 7  wherein the uniform variance of the second grooves converges toward an outside edge of the apparatus.  
   
   
       9 . The apparatus of  claim 8  wherein each of the second grooves provides a depression adjacent an outside edge of the apparatus.
