Bracket assembly for window blind

Abstract

A bracket assembly includes a bracket provided with a coupling portion, a locating frame provided with a coupling portion connectable to the coupling portion of the bracket, and a level mounted on the locating frame for showing whether the bracket is in level after connection of the coupling portion of the locating frame to the coupling portion of the bracket. By means of the indication of the level, the bracket can easily be adjusted to horizontal during installation of the bracket assembly in a window.

1 . A bracket assembly for a window blind, comprising: 
 an elongated bracket having a coupling portion;    a locating frame having a coupling portion connectable to the coupling portion of said bracket; and    a level mounted on said locating frame.    
   
   
       2 . The bracket assembly as claimed in  claim 1 , wherein said bracket comprises two end plates, said end plates each having a pivot hole for supporting a roller of the window blind in parallel to said bracket between said end plates.  
   
   
       3 . The bracket assembly as claimed in  claim 1 , wherein said locating frame comprises a top wall, a first sidewall extended from a front side of said top wall, and a second sidewall extended from a rear side of said top wall; wherein the coupling portion of said locating frame is protruded from a bottom side of said second sidewall toward said first sidewall; said level is located at a bottom side of said first sidewall of said locating frame.  
   
   
       4 . The bracket assembly as claimed in  claim 2 , wherein said level is substantially maintained in parallel to an axis passing through the pivot holes of said end plates of said bracket.  
   
   
       5 . The bracket assembly as claimed in  claim 1 , wherein said level is substantially maintained in parallel to an elongated sidewall of said bracket.  
   
   
       6 . The bracket assembly as claimed in  claim 1 , wherein said bracket is an substantially L-shaped member comprising a top wall, a sidewall, and an angled top flange upwardly protruded from said top wall; the coupling portion of said bracket is defined within a space surrounded by the top wall and angled top flange of said bracket; the coupling portion of said bracket comprising a top edge, a bottom edge, and an opening facing a rear side of said bracket; the coupling portion of said locating frame comprises a top edge and a bottom edge respectively attachable to the top edge and bottom edge of the coupling portion of said bracket.  
   
   
       7 . The bracket assembly as claimed in  claim 6 , wherein the top edge and bottom edge of the coupling portion of said bracket are arranged in parallel and spaced from each other by a gap; the top edge and bottom edge of the coupling portion of said locating frame are arranged in parallel and spaced from each other by a distance substantially equal to the gap between the top edge and bottom edge of the coupling portion of said bracket.  
   
   
       8 . The bracket assembly as claimed in  claim 7 , wherein said level is maintained in parallel to the top edge of the coupling portion of said bracket.  
   
   
       9 . The bracket assembly as claimed in  claim 1 , wherein said bracket is an elongated flat member set in vertical; the coupling portion of said bracket is provided at a top side of said bracket, comprising a left-side edge, a right-side edge, and an opening facing upwards; the coupling portion of said locating frame is a coupling block insertable into the opening of the coupling portion of said bracket, comprising a left-side edge and a right-side edge respectively attachable to the left-side edge and right-side edge of the coupling portion of said bracket.  
   
   
       10 . The bracket assembly as claimed in  claim 9 , wherein the left-side edge and right-side edge of the coupling portion of said bracket are arranged in parallel and spaced from each other by a gap; the left-side edge and right-side edge of the coupling portion of said locating frame are arranged in parallel and spaced from each other by a distance approximately equal to the gap between the left-side edge and right-side edge of the coupling portion of said bracket.  
   
   
       11 . The bracket assembly as claimed in  claim 10 , wherein said level is maintained in parallel to the left-side edge of the coupling portion of said bracket.  
   
   
       12 . The bracket assembly as claimed in  claim 1 , wherein said level is a bubble level.  
   
   
       13 . The bracket assembly as claimed in  claim 1 , wherein said level is an electronic level.  
   
   
       14 . A bracket assembly for a window blind, comprising: 
 an elongated bracket; and    a level fixedly mounted on said bracket.    
   
   
       15 . The bracket assembly as claimed in  claim 14 , wherein said bracket comprises two end plates, said end plates each having a pivot hole for supporting a roller of the window blind between said end plates in parallel to said bracket.  
   
   
       16 . The bracket assembly as claimed in  claim 15 , wherein said level is substantially maintained in parallel to an axis passing through the pivot holes of said end plates of said bracket.  
   
   
       17 . The bracket assembly as claimed in  claim 14 , wherein said level is substantially maintained in parallel to an elongated sidewall of said bracket.  
   
   
       18 . The bracket assembly as claimed in  claim 14 , wherein said bracket is a substantially L-shaped member comprising a top wall and a sidewall.  
   
   
       19 . The bracket assembly as claimed in  claim 14 , wherein said bracket is an elongated flat member set in vertical.  
   
   
       20 . The bracket assembly as claimed in  claim 14 , wherein said level is a bubble level.  
   
   
       21 . The bracket assembly as claimed in  claim 14 , wherein said level is an electronic level.
