Decorative ceiling beam

Abstract

In at least one embodiment, the present invention provides a decorative ceiling beam assembly having a longitudinally extending reversible base plate, a longitudinally extending first side wall portion, a longitudinally extending second side wall portion and a longitudinally extending reversible bottom plate such that the components interfit to create a longitudinally extending, rectangularly prismatic decorative ceiling beam having a hollow cross section.

What is claimed is: 
     
         1 . A decorative ceiling beam assembly comprising:
 A longitudinally extending reversible base plate having a longitudinally extending first edge and a longitudinally extending second edge, the longitudinally extending first edge having a first longitudinally extending parallel and spaced apart outwardly projecting flange thereby defining a longitudinally extending outwardly opening first upper groove therebetween, the longitudinally extending second edge having a second longitudinally extending parallel and spaced apart outwardly projecting flange thereby defining a longitudinally extending outwardly opening second upper groove therebetween;   A longitudinally extending first side wall portion having a longitudinally extending first upper edge and a longitudinally extending first lower edge, the first upper edge having a longitudinally extending inwardly projecting first upper flange, the first lower edge having a longitudinally extending inwardly projecting first lower flange;   A longitudinally extending second side wall portion having a longitudinally extending second upper edge and a longitudinally extending second lower edge, the second upper edge having a longitudinally extending inwardly projecting second upper flange, the second lower edge having a longitudinally extending inwardly projecting second lower flange; and   A longitudinally extending reversible bottom plate having a longitudinally extending first edge and a longitudinally extending second edge, the longitudinally extending first edge having a longitudinally extending first parallel and spaced apart outwardly projecting flange thereby defining a longitudinally extending outwardly opening first lower groove therebetween, the longitudinally extending second edge having a second longitudinally extending parallel and spaced apart outwardly projecting flange thereby defining a longitudinally extending outwardly opening second lower groove therebetween;   
       wherein the first upper groove of the reversible base plate securely receives at least one of the longitudinally extending inwardly projecting first upper flange of the first side wall portion and the longitudinally extending inwardly projecting first upper flange of the second side wall portion, the second upper groove of the reversible base plate securely receives the other of the longitudinally extending inwardly projecting second upper flange of the first side wall portion and the longitudinally extending inwardly projecting second upper flange of the second side wall portion and the outwardly opening first lower groove of the bottom plate receives one of the inwardly projecting first lower flange of the first side wall portion and the inwardly projecting second lower flange of the second side wall portion and the outwardly opening second lower groove of the bottom plate receives the other of the inwardly projecting first lower flange of the first side wall portion and the inwardly projecting second lower flange of the second side wall portion so as to create a rectangularly prismatic, longitudinally extending decorative ceiling beam. 
     
     
         2 . The decorative ceiling beam assembly of  claim 1  wherein at least one of the first inwardly projecting upper flange, the second inwardly projecting upper flange, the first inwardly projecting lower flange and the second inwardly projecting lower flange further comprises a longitudinally extending first sloped portion and an opposed longitudinally extending second sloped portion defining a longitudinally extending tab element therebetween, the longitudinally extending tab element having a longitudinally extending first tab wall and a parallel and opposed longitudinally extending second tab wall and a longitudinally extending tab edge. 
     
     
         3 . The decorative ceiling beam assembly of  claim 2  wherein the cross-sectional shape of the longitudinally extending tab edge is semi-obround. 
     
     
         4 . The decorative ceiling beam assembly of  claim 2  wherein at least one of the first tab wall and the second tab wall further include at least one longitudinally extending securing ridge. 
     
     
         5 . The decorative ceiling beam assembly of  claim 1  wherein at least one of the first edge and the second edge of the reversible bottom plate are chamfered. 
     
     
         6 . The decorative ceiling beam assembly of  claim 1  wherein at least one of the first edge and the second edge of the reversible base plate are chamfered. 
     
     
         7 . The decorative ceiling beam assembly of  claim 1  wherein a distal edge of at least one of the first parallel and spaced apart outwardly projecting flange of the reversible bottom plate, the second parallel and spaced apart outwardly projecting flange of the reversible bottom plate, the first parallel and spaced apart outwardly projecting flange of the reversible base plate and the second parallel and spaced apart outwardly projecting flange of the reversible base plate are chamfered. 
     
     
         8 . The decorative ceiling beam assembly of  claim 1  wherein at least one of the first groove and the second groove of the reversible bottom plate and the first groove and the second groove of the reversible base plate further comprises a longitudinally extending first groove wall and a longitudinally extending parallel and opposed second groove wall, at least one of the first groove wall and the second groove wall further including at least one longitudinally extending securing ridge. 
     
     
         9 . The decorative ceiling beam assembly of  claim 1  wherein the decorative ceiling beam assembly is comprised of extruded plastic components.
