Corner key with angled ribs

Abstract

A corner key frame bracket is a body defining first and second sides. The multi-position bracket includes two slots on either leg to allow the insertion of a screw so as to force the bracket in contra directions to provide a secure and tight seal of the window framing unit. Each corner bracket key has a leg capable of insertion into at least one partially hollow longitudinal cavity of a framing unit.

 (a) said inwardly deflecting means is an inwardly facing rib in connected relationship with said channel walls.  
 
     
     
         12 . A window framing system which comprises: 
 (a) at least three at least partially hollow window frames, 
 (i) each of said window frames mitered at an angle so as to effect complete closure of the frame,  
 (ii) each of said window frames having at least two apertures disposed therein; and  
   (b) a key comprising, 
 (i) a pair of laterally extending legs, each of said legs joined at a vertex and at least partially inserted into said at least partially hollow window frames, each leg comprising  
 (ii) a pair of walls and a floor in connected relationship with said walls forming a channel,  
 (iii) each floor having an aperture disposed therein;  
   (c) each channel comprising 
 (i) at least one inwardly facing rib in connected relationship with said channel walls positioned so as to intersect a vertical axis of said at least one aperture in each of said channel floors, each of said at least one aperture in colinear alignment with said aperture in each of said window frames.  
   
     
     
         13 . The device of  claim 12  wherein 
 (a) an angle defined between said floor and said inwardly angled rib is from approximately between 10° and 80° inclusive.

 (a) said angle is from approximately 45° and 70°.  
 
     
     
         15 . The device of  claim 12  wherein 
 (a) at least one pair of channel walls have a taper at an end thereof.  
 
     
     
         16 . The device of  claim 15  wherein 
 (a) both pairs of channel walls have a taper at said ends.  
 
     
     
         17 . A window framing system which comprises: 
 (a) At least three at least partially hollow window frames, 
 (i) each of said window frames mitered at an angle so as to effect complete closure of the frame,  
 (ii) each of said window frames having at least two apertures disposed therein; and
