Pavement edging device

Abstract

The present invention is a pavement edging device consisting of an elongated extrusion having a flat bottom portion, said bottom portion having opposite first and second side edges. The extrusion also has a trough formed from first and second spaced apart parallel wall portions extending upwardly from the bottom portion between the first and second side edges. The wall portions have first and second top edges, respectively. The extrusion also has first and second flange portions formed on the bottom adjacent the first and second side edges, respectively. The first and second flange portions extend away from the first and second wall portions, respectively.

Therefore, what is claimed is:  
     
         1 . A pavement edging device comprising: 
 an elongated extrusion having a flat bottom portion, said bottom portion having opposite first and second side edges;    first and second spaced apart parallel wall portions extending upwardly from the bottom portion between the first and second side edges, said wall portions having first and second top edges, respectively, said walls forming an elongated trough;    first and second flange portions formed on the bottom adjacent the first and second side edges, respectively, said first and second flange portions extending away from the first and second wall portions, respectively.    
     
     
         2 . The pavement edging device of  claim 1  wherein the wall portions extend perpendicularly from the bottom portion.  
     
     
         3 . The pavement edging device of  claim 2  wherein the first flange is provided with a plurality of apertures.  
     
     
         4 . The pavement edging device of  claim 3  wherein the second flange is provided with at least one aperture.  
     
     
         5 . The pavement edging device of  claim 2 ,  3  and  4  wherein the bottom portion has apertures between the walls.  
     
     
         6 . The pavement edging device of  claim 1  further comprising a brace extending contiguously between the second walls.  
     
     
         7 . The pavement edging device of  claim 6  wherein the first and second walls extend perpendicularly from the bottom.  
     
     
         8 . The pavement edging device of  claim 7  wherein the brace extends perpendicularly from the first and second walls.  
     
     
         9 . The pavement edging device of  claim 8  wherein the brace is positioned between the top edges of the walls and the bottom portion.  
     
     
         10 . The pavement edging device of  claim 9  wherein the brace is oriented parallel to the bottom portion and extends substantially the entire length of the extrusion.  
     
     
         11 . The pavement edging device of  claim 10  wherein the first flange is provided with a plurality of apertures.  
     
     
         12 . The pavement edging device of  claim 11  wherein the second flange is provided with at least one aperture.  
     
     
         13 . The pavement edging device of  claim 10 ,  11  and  12  wherein the bottom portion has apertures between the walls.  
     
     
         14 . A pavement edging device comprising: 
 an elongated extrusion having a length and a flat bottom portion, said bottom portion having opposite first and second side edges;    first and second spaced apart parallel wall portions extending perpendicularly upwards from the bottom portion between the first and second side edges, said wall portions extending substantially the entire length of the extrusion, said wall portions having first and second top edges, respectively, said wall portions forming an elongated trough;    first and second flange portions formed on the bottom adjacent the first and second side edges, respectively, said first and second flange portions extending away from the first and second wall portions, respectively, said flange portions extending substantially the entire length of the extrusion, and    a brace portion extending contiguously between the first and second wall portions along the length of the extrusion, said brace portion extending perpendicularly from the walls between the top edges of the walls and the bottom portion, said brace oriented parallel to the bottom portion.
