Abstract

A window curtain assembly is disclosed. The window curtain assembly includes a headrail, take up member, a pair of panels affixed to the headrail, and a pair of lift cords attached to the take up member and each panel. Rotation of the take up member winds the lift cords around the take up member moving the panels upwardly and away from each other to open the curtain.

1 . A window curtain assembly comprising: 
 a pair of panels, each panel having a top edge, a side edge, and a bottom edge, the side edges of each panel being positioned proximate each other; and    a headrail including a winding mechanism mounted thereto, the winding mechanism including an elongate rod coupled to at least a first cord take up mechanism for winding a pair of lift cords affixed to the panels, the top edge of each panel affixed to the headrail, wherein rotation of the at least one take up mechanism causes the lift cords to move at least a portion of the side edges upwardly and away from each other.    
     
     
         2 . The window curtain assembly according to  claim 1 , further comprising a clutch mechanism coupled to the elongate rod, wherein actuation of the clutch mechanism causes rotation of the elongate rod.  
     
     
         3 . The window curtain assembly according to  claim 2 , further comprising a pull mechanism coupled to the clutch mechanism for actuating the clutch mechanism.  
     
     
         4 . The window curtain assembly according to  claim 3 , wherein the pull mechanism is a chain or cord in the form of a loop or is multiple chains or cords.  
     
     
         5 . The window curtain assembly according to  claim 1 , further comprising at least one ring on each panel for guiding the lift cords.  
     
     
         6 . The window curtain assembly according to  claim 5 , further comprising a plurality of rings, wherein the plurality of rings is arranged in an arcuate pattern or in a straight pattern.  
     
     
         7 . The window curtain assembly according to  claim 1 , wherein at least a portion of the inside edges of said panels overlaps one another.  
     
     
         8 . The window curtain assembly according to  claim 1 , wherein the top edge of each panel are removably affixed to the headrail and the pair of lift cords are removably affixed to said panels.  
     
     
         9 . A window curtain assembly comprising: 
 a headrail;    first and second fabric panels affixed to the headrail in a side-by-side relation, each panel having an inner edge and an outer edge; and    means for moving the inner edges upwardly and away from each other operatively engaged with a pull mechanism to open said panels.    
     
     
         10 . The window curtain assembly according to  claim 9 , further comprising means for preventing unintentional opening or closure of said curtain.  
     
     
         11 . The window curtain assembly according to  claim 10 , wherein said means for preventing unintentional opening or closure of said curtain is a conventional cord lock.  
     
     
         12 . The window curtain assembly according to  claim 10 , wherein said means for moving the inner edges upwardly and away from each other is a take up member operatively engaged with the means for preventing unintentional moving of the inner edges.  
     
     
         13 . The window curtain assembly according to  claim 12 , wherein the means for preventing unintentional opening and closure of said curtain includes a clutch mechanism.  
     
     
         14 . The window curtain assembly according to  claim 13 , wherein the take up member includes an elongate rod and at least one spool.  
     
     
         15 . A window curtain assembly comprising: 
 at least one panel, said at least one panel having a top edge, a side edge, and a bottom edge; and    a headrail including a winding mechanism mounted thereto, the winding mechanism including an elongate rod coupled to at least a first cord take up mechanism for winding at least one lift cord affixed to the side edge of said at least one panel, the top edge of said at least one panel affixed to the headrail, wherein rotation of the at least one take up mechanism causes the at least one lift cord to move at least a portion of the side edge.    
     
     
         16 . The window curtain assembly according to  claim 15 , further comprising a clutch mechanism coupled to the elongate rod, wherein actuation of the clutch mechanism causes rotation of the elongate rod.  
     
     
         17 . The window curtain assembly according to  claim 16 , further comprising a pull mechanism coupled to the clutch mechanism for actuating the clutch mechanism.  
     
     
         18 . The window curtain assembly according to  claim 17 , wherein the pull mechanism is a chain or cord in the form of a loop or is multiple chains or cords.  
     
     
         19 . The window curtain assembly according to  claim 18 , further comprising a plurality of rings on said at least one panel for guiding the at least one lift cord, wherein the plurality of rings is arranged in an arcuate pattern or in a straight pattern.  
     
     
         20 . The window curtain assembly according to  claim 19 , wherein the top edge of said at least one panel is removably affixed to the headrail and the at least one lift cord is removable affixed to said at least one panel.
