Adjustable corner bead

Abstract

An adjustable corner bead which can join two wall members or board members at a plurality of angles can be set up relatively easily, and is portable, easy to transport, and easy to store. The adjustable corner bead has a first support member and a second support member. The first support member has a substantially flat portion adapted to be secured to a wall or board member, and also has a curved portion formed by two curved members extending substantially in parallel with each other from one end of the substantially flat portion. The two curved members form a slot therebetween. The second support member has a substantially flat portion adapted to be secured to a wall or board member, and has a curved portion formed by a single curved member which is adapted to be received within the slot formed in the first support member. Each of the curved portions has a shape corresponding to the outmost surface of a substantially right regular cylindical member. The flat portion of the first support member and the flat portion of the second support member have a plurality of holes therethrough for passage of nails, bolts, brads, or any other types of fasteners known in the construction industry.

1 . An adjustable corner bead adapted to join two wall members or board members at a selectable angle, comprising: 
 a first support member having a substantially flat portion adapted to be secured to a wall or board member and a curved portion, the curved portion including two curved members extending substantially in parallel with each other so that a slot is formed therebetween; the curved portion being disposed at one end of the substantially flat portion; and    a second support member having a substantially flat portion adapted to be secured to a wall or board member, and having has a curved portion which includes only a single curved member which is adapted to be received within the slot formed between the two curved members of the first support member.    
   
   
       2 . An adjustable corner bead as claimed in  claim 1 , wherein each of the curved portions has a shape corresponding to the outmost surface of a substantially right regular cylindical member, such that each of the curved portions has a fixed radius of curvature.  
   
   
       3 . An adjustable corner bead as claimed in  claim 1 , wherein the flat portion of the first support member and the flat portion of the second support member have a plurality of holes therethrough for passage of fasteners for securement to a wall member or board member.  
   
   
       4 . An adjustable corner bead as claimed in  claim 3 , wherein the first support member and the second support member are composed of light gauge galvanized steel, so as to be rust resistant.  
   
   
       5 . An adjustable corner bead adapted to join two wall members or board members at a selectable angle, comprising: 
 A first support member having a substantially flat body portion adapted to be secured to a wall or board member, and having has male end portion, the male end portion comprising a single curved member;    a second support member having a substantially flat body portion adapted to be secured to a wall or board member, and having a female end portion; the female end portion being a curved portion which includes two curved members extending substantially coaxially with each other so as to form a slot therebetween; the curved female portion being disposed at one end of the substantially flat body portion;    wherein the single curved member of the male portion being adapted to be slideably received within the slot formed between the two curved members of the female portion of the first support member.    
   
   
       6 . An adjustable corner bead as claimed in  claim 5 , wherein each of the two curved members of the female portion of the first support member has a shape corresponding to the outmost surface of a substantially right regular cylindical member, such that each of the curved portions has a fixed radius of curvature.  
   
   
       7 . An adjustable corner bead as claimed in  claim 5 , wherein the flat portion of the first support member and the flat portion of the second support member have a plurality of holes therethrough for passage of fasteners for securement to a wall member or board member; and wherein one of the two curved members of the female portion has a stop member portion at its distal end and the male end portion has a stop member portion at its distal end, such that disengagement of the first and second support member is prevented by engagement of the stop member portions.  
   
   
       8 . An adjustable corner bead as claimed in  claim 7 , wherein the first support member and the second support member are composed of light gauge galvanized steel, so as to be rust resistant.  
   
   
       9 . An adjustable corner bead as claimed in  claim 7 , wherein the first support member and the second support member are composed of plastic polymer material, so as to be rust resistant.
