Curtain Assembly

Abstract

A curtain assembly includes a headrail, a curtain, a safety loop, and a pull rope. The curtain is coupled to the headrail. The safety loop has a first loop portion that is fastened to the curtain, and a second loop portion that includes first and second arms, each of which extends from the first loop portion and has a free end. The first and second arms of the second loop portion define a hole therebetween. The pull rope extends through the hole in the second loop portion of the safety loop, has an end fastened to the curtain, and is operable so as to raise or lower the curtain.

1 . A curtain assembly comprising:
 a headrail;   a curtain coupled to said headrail;   a safety loop having a first loop portion that is fastened to said curtain, and a second loop portion that includes first and second arms, each of which extends from said first loop portion and has a free end, said first and second arms of said second loop portion defining a hole therebetween; and   a pull rope extending through said hole in said second loop portion of said safety loop, having an end fastened to said curtain, and operable so as to raise or lower said curtain, whereby when said pull rope is pulled away from said curtain, said pull rope is released from said safety loop between said free ends of said first and second arms of said second loop portion of said safety loop.   
     
     
         2 . The curtain assembly as claimed in  claim 1 , wherein said first loop portion includes a first arm, and a second arm that extends from said first arm of said first loop portion, and that cooperates with said first arm of said first loop portion to define a hole therebetween. 
     
     
         3 . The curtain assembly as claimed in  claim 2 , wherein said second loop portion further includes third and fourth arms, each of which interconnects said first arm of said first loop portion and said free end of a respective one of said first and second arms of said second loop portion. 
     
     
         4 . The curtain assembly as claimed in  claim 1 , wherein said hole in said second loop portion has an elliptical shape and is defined by a major axis, said free ends of said first and second arms of said second loop portion being disposed along the major axis of said hole in said second loop portion. 
     
     
         5 . The curtain assembly as claimed in  claim 2 , wherein each of said first and second arms of said first loop portion has an end, said ends of said first and second arms of said first loop portion defining a gap therebetween that is in spatial communication with said hole in said first loop portion. 
     
     
         6 . The curtain assembly as claimed in  claim 5 , wherein:
 said end of said first arm of said first loop portion is formed with a protrusion that protrudes toward said end of said second arm of said first loop portion; and   said end of said second arm of said first loop portion is formed with a protrusion that protrudes toward said end of said first arm of said first loop portion.   
     
     
         7 . The curtain assembly as claimed in  claim 1 , wherein said free ends of said first and second arms of said second loop portion define a gap therebetween that is in spatial communication with said hole in said second loop portion,
 said free end of said first arm of said second loop portion having a surface,   said free end of said second arm of said second loop portion having a surface opposed to said surface of said free end of said first arm of said second loop portion,   said surfaces of said free ends of said first and second loop portions diverge in a direction toward said hole in said second loop portion.   
     
     
         8 . The curtain assembly as claimed in  claim 1 , further comprising a fastening unit including a ring that is fastened to one of said curtain and said end of said pull rope, and a plate that is fastened to the other of said curtain and said end of said pull rope, said plate being formed with an engaging groove that engages releasably said ring.
