Frame section for a black-out blind assembly

Abstract

A black-out blind assembly having a frame supporting a black-out blind moveable within the frame between open and closed positions wherein sections of the frame have inner and outer walls extending from a side wall so as to form a channel section defining a recess for receiving part of a black-out blind. A light absorbing substantially non-reflective insert is positioned within the recess of the channel section adjacent the inner, outer and side walls so as to prevent scattered and reflected light passing around the sides of the black-out blind.

1 . A frame section of a frame for a black-out blind assembly supporting a black-out blind moveable within the frame between open and closed positions, the frame section having: 
 inner and outer walls extending from a side wall so as to form a channel section defining a recess for receiving part of a black-out blind; and    a light absorbing substantially non-reflective insert positioned within the recess of the channel section adjacent the inner, outer and side walls.    
     
     
         2 . A frame section according to  claim 1  wherein the insert is a sheet form extending between first and second generally parallel edges and is deformed so as to extend from the first edge adjacent the inner wall around the inside of the channel section to the second edge adjacent the outer wall.  
     
     
         3 . A frame section according to  claim 1  wherein, within the recess of the channel section, the inner and outer walls are provided with respective supports for receiving the first and second edges of the insert.  
     
     
         4 . A frame section according to  claim 3  wherein one or more of the supports include protrusions extending into the recess of the channel section so as to prevent the edges of the insert moving outwardly of the channel section.  
     
     
         5 . A frame section according to  claim 3  wherein one or more of the supports define respective openings facing inwardly of the recess of the channel section for receiving the edges of the insert.  
     
     
         6 . A frame section according to  claim 3  wherein one or more of the supports from elongate channels.  
     
     
         7 . A frame section according to  claim 1  wherein the insert is at least partly resilient such that, once inserted in the recess of the channel section, the insert presses outwardly against the inner, outer and side walls.  
     
     
         8 . A frame section according to  claim 1  wherein the insert is a black material, such as a non-woven material, paper, woven fabric, non-woven fabric, extruded flat film and extruded film in shape.  
     
     
         9 . A frame section according to  claim 1  wherein the frame section is arranged to receive an edge of sheet forming a black-out blind, the edge sliding along the channel section as the black-out blind is moved between open and closed positions.  
     
     
         10 . A frame section according to  claim 1  wherein the frame section is arranged to receive a rolled sheet forming a black-out blind, the sheet being unrolled from and rolled into the frame section as the black-out blind is moved between open and closed positions.  
     
     
         11 . A frame section according to  claim 10  further including supports at each of two ends of the frame section for rotatably supporting therebetween a rolled sheet forming a black-out blind.  
     
     
         12 . A black-out blind assembly comprising: 
 a frame having at least one frame section including inner and outer walls extending from a side wall so as to form a channel section defining a recess for receiving part of a black-out blind and a light absorbing substantially non-reflective insert positioned within the recess of the channel section adjacent the inner, outer and side walls; and    a black-out blind moveable within the frame.
