Multi-angle exterior drywall corner bead

Abstract

A drywall corner bead made of high-impact plastic or other material that can be in-elastically bent to any angle at the bead itself. The corner bead can have a front layer of paper or other material capable of directly receiving paint or texture and an optional backing layer of paper or other fibrous material. The bead can be bent and re-bent inelastically as many times as needed to fit a corner.

1 . A drywall corner bead comprising: 
 an elongated semi-rigid non-metal flange with a central apex along a centerline end-to-end, said apex forming a bead in-elastically bendable at said bead along said centerline to form any angle;    a covering layer on a room-facing surface of said semi-rigid flange, said covering layer capable of directly receiving paint or texture.    
   
   
       2 . The drywall corner bead of  claim 1  wherein said semi-rigid flange is high-impact plastic.  
   
   
       3 . The drywall corner bead of  claim 1  further comprising a backing layer of fibrous material on a wall-facing side of said semi-rigid flange.  
   
   
       4 . The drywall corner bead of  claim 1  wherein said covering layer is cupstock paper.  
   
   
       5 . The drywall corner bead of  claim 1  wherein said flange is tapered from said apex to each of a pair of edges.  
   
   
       6 . The drywall corner bead of  claim 1  wherein said apex is a sharp point.  
   
   
       7 . The drywall corner bead of  claim 1  wherein said apex is bullnose.  
   
   
       8 . A drywall corner bead including a non-metal elongated flange with an inelastic centerline region that can be bent along a center line to match any wall angle and wherein, the flange is covered with a layer of cupstock paper, and the flange is tapered from a thicker region along the centerline region to thinner regions along its edges.  
   
   
       9 . The drywall corner bead of  claim 8  wherein the flange is high impact plastic.  
   
   
       10 . The drywall corner bead of  claim 8  wherein said layer of cupstock paper extends beyond said edges.  
   
   
       11 . A universal drywall bead comprising a pair of elongated high impact plastic flanges connected together side-by-side with an inelastic center region, said flanges being capable of being bent and re-bent repeatably to a plurality of different angles about said centerline, said flanges also being tapered from said center region outward to edges, the flanges covered on a room-facing side with a layer of cupstock paper.  
   
   
       12 . The universal drywall bead of  claim 11  further comprising a layer of paper on a wall-facing surface of said flanges.  
   
   
       13 . The universal drywall bead of  claim 11  wherein said flanges contain a plurality of holes.
