Curtain

Abstract

A curtain has a substrate, multiple horizontal row assemblies, a rope and at least one flexible tube. The horizontal row assemblies are mounted horizontally on a surface of the substrate at intervals and each horizontal row assembly has at least one rope-extended element. The rope is extended vertically through the rope-extended elements to form multiple rope segments and has two ends fastened to the rope-extended elements near the bottom of the substrate. The flexible tube is fastened to the rear surface of the substrate and at least sheathes the at least one rope segment between the two horizontal row assemblies near a bottom of the substrate. Children cannot touch or pull the rope, which is sheathed by the flexible tubes fastened to the substrate, so the curtain is safe.

1 . A curtain comprising:
 a substrate;   multiple horizontal row assemblies mounted horizontally on a surface of the substrate at intervals and each horizontal row assembly having at least one rope-extended element;   a rope extended vertically through the rope-extended elements to form multiple rope segments between two rope-extended elements respectively at each two horizontal row assemblies in a same vertical and having two ends fastened to the rope-extended elements near the bottom of the substrate; and   at least one flexible tube fastened to the rear surface of the substrate and at least sheathing the at least one rope segment between the two horizontal row assemblies near a bottom of the substrate.   
     
     
         2 . The curtain as claimed in  claim 1 , wherein each horizontal row assembly has
 a rod mounted horizontally on the surface of the substrate at intervals in parallel; and   multiple rings served as the rope-extended elements and horizontally mounted on the rod at intervals.   
     
     
         3 . The curtain as claimed in  claim 1 , wherein each horizontal row assembly essentially consists of multiple rings that are served as the rope-extended elements and are horizontally mounted on the surface of the substrate at intervals. 
     
     
         4 . The curtain as claimed in  claim 1 , wherein each flexible tube is fastened thoroughly to the surface of the substrate. 
     
     
         5 . The curtain as claimed in  claim 2 , wherein each flexible tube is fastened thoroughly to the surface of the substrate. 
     
     
         6 . The curtain as claimed in  claim 3 , wherein each flexible tube is fastened thoroughly to the surface of the substrate. 
     
     
         7 . The curtain as claimed in  claim 1 , wherein each flexible tube has two end portions and a middle portion and each flexible tube is fastened to the surface of the substrate only by the end portions and an interval is formed between the middle portion and the surface of the substrate. 
     
     
         8 . The curtain as claimed in  claim 2 , wherein each flexible tube has two end portions and a middle portion and each flexible tube is fastened to the surface of the substrate only by the end portions and an interval is formed between the middle portion and the surface of the substrate. 
     
     
         9 . The curtain as claimed in  claim 3 , wherein each flexible tube has two end portions and a middle portion and each flexible tube is fastened to the surface of the substrate only by the end portions and an interval is formed between the middle portion and the surface of the substrate. 
     
     
         10 . The curtain as claimed in  claim 1  having multiple flexible tubes sheathing all the rope segments. 
     
     
         11 . The curtain as claimed in  claim 2  having multiple flexible tubes sheathing all the rope segments. 
     
     
         12 . The curtain as claimed in  claim 3  having multiple flexible tubes sheathing all the rope segments. 
     
     
         13 . The curtain as claimed in  claim 1 , wherein each flexible tube is made of cloth, is sewed onto the surface of the substrate and has
 an upper end;   a lower end having an opening; and   a middle part;   wherein a dimension of the upper end is smaller than a dimension of the lower end and the upper end is located in the opening of the lower end and the middle part is located in the opening between the upper end and the lower end when the flexible tube is folded.   
     
     
         14 . The curtain as claimed in  claim 2 , wherein each flexible tube is made of cloth, is sewed onto the surface of the substrate and has
 an upper end;   a lower end having an opening; and   a middle part;   wherein a dimension of the upper end is smaller than a dimension of the lower end and the upper end is located in the opening of the lower end and the middle part is located in the opening between the upper end and the lower end when the flexible tube is folded.   
     
     
         15 . The curtain as claimed in  claim 3 , wherein each flexible tube is made of cloth, is sewed onto the surface of the substrate and has
 an upper end;   a lower end having an opening; and   a middle part;   wherein a dimension of the upper end is smaller than a dimension of the lower end and the upper end is located in the opening of the lower end and the middle part is located in the opening between the upper end and the lower end when the flexible tube is folded.   
     
     
         16 . The curtain as claimed in  claim 4 , wherein each flexible tube is made of cloth, is sewed onto the surface of the substrate and has
 an upper end;   a lower end having an opening; and   a middle part;   wherein a dimension of the upper end is smaller than a dimension of the lower end and the upper end is located in the opening of the lower end and the middle part is located in the opening between the upper end and the lower end when the flexible tube is folded.   
     
     
         17 . The curtain as claimed in  claim 7 , wherein each flexible tube is made of cloth, is sewed onto the surface of the substrate and has
 an upper end;   a lower end having an opening; and   a middle part;   wherein a dimension of the upper end is smaller than a dimension of the lower end and the upper end is located in the opening of the lower end and the middle part is located in the opening between the upper end and the lower end when the flexible tube is folded.   
     
     
         18 . The curtain as claimed in  claim 10 , wherein each flexible tube is made of cloth, is sewed onto the surface of the substrate and has
