Safety structure of curtain

Abstract

A safety structure of a curtain includes a main body having a beam and a curtain body with an end coupled to the beam, and the curtain body includes connecting portions; first latches at another end of the curtain body; second latches separately on each connecting portion; an ascending/descending unit coupled to the main body and including a position limit element in the beam, and a link string with an end coupled to the first latch, passed through the second latch and connected to the position limit element; and third latches installed at another end of the link string, and each third latch includes a pull string, such that if a too-large force is applied to the link or pull string, the connecting portions, first, second and third latches will be separated to prevent the pull string from being wound around a human body and achieve a higher safety effect.

1 . A safety structure of a curtain, comprising:
 a main body, including a beam, a curtain body with an end coupled to the beam, and a plurality of connecting portions disposed on the curtain body;   a plurality of first latches, separately installed at another end of the curtain body;   a plurality of second latches, separately installed on each connecting portion;   an ascending/descending unit, coupled to the main body, and having a position limit element installed in the beam, and a link string coupled to an end of the first latch, passed through the second latch, and coupled to the position limit element; and   a plurality of third latches, installed at another end of the link string, and each third latch including a pull string installed thereon.   
     
     
         2 . The safety structure of a curtain as recited in  claim 1 , wherein the curtain body includes a weight portion disposed at another end of the curtain body. 
     
     
         3 . The safety structure of a curtain as recited in  claim 1 , wherein each connecting portion is coupled to the curtain body by a sewing thread. 
     
     
         4 . The safety structure of a curtain as recited in  claim 1 , wherein each first latch includes an embedding portion disposed at another end of the curtain body, a latch portion movably latched with the embedding portion, and a fixing hole formed on each latch portion for coupling an end of the link string. 
     
     
         5 . The safety structure of a curtain as recited in  claim 1 , wherein each second latch includes a fixing base disposed on the connecting portion, and a clamp portion movably latched with the fixing base, and each clamp portion includes a through hole provided for passing and coupling the link string. 
     
     
         6 . The safety structure of a curtain as recited in  claim 1 , wherein each third latch includes a pair of connectors installed to the link string and the pull string respectively and movably engaged with each other.
