Curtain with a light adjusting structure

Abstract

A curtain with a light adjusting structure includes an adjusting unit having a control reel module and a hanging reel. Each transversal vane includes a side frame pivotally coupled to both ends of the top of the curtain. The rear section of a first pulling cord is coupled with the lower edge of each vane and passed through the control reel module. A second pulling cord winds the hanging reel such that the front section passes around another control reel module and is situated in front of the curtain, and the rear section is fixed to the rear side of the bottom of the curtain. A third pulling cord winds another control reel module and fixes its rear section to the bottom of the curtain. Pulling the first pulling cord can lift each vane, and pulling the second and third pulling cords can draw the curtain upward.

1 . A curtain with a light adjusting structure, comprising: 
 an adjusting unit, coupled to the top of said curtain, and said adjusting unit further comprising a control reel module for clamping a first pulling cord and a hanging reel provided for a second pulling cord to roll up said curtain, and said curtain being comprised of a plurality of transversal vanes thereunder, and both ends of the top of said each vane being pivotally coupled to a side frame on both sides of said curtain, and said first pulling cord being passed through said control reel module, thereby its rear section is passed through said curtain and situated at the back of said curtain and coupled with the bottom of said each vane, and the front section of said first pulling cord is drooped in front of said curtain, and said second pulling cord is wound around said hanging reel, thereby its rear section is coupled to a transversal rod disposed at the bottom of the back of said curtain, and its front section is wound around and clamped by another control reel module on the other side of said curtain, and said other control reel module of said curtain is provided for winding a third pulling cord, such that said third pulling cord is passed through said curtain and disposed at the back of said curtain, and its bottom is coupled to said transversal rod, and the front section of said third pulling cord is drooped in front of said curtain.    
     
     
         2 . The curtain with a light adjusting structure of  claim 1 , wherein said control reel module further comprises a hollow housing, a wheel pivotally coupled to an interior front section and an interior rear section of said housing, and a clamping reel disposed inside said housing and capable of moving vertically up and down, and said first pulling cord is passed between said wheel and said clamping reel.  
     
     
         3 . The curtain with a light adjusting structure of a curtain of  claim 1 , wherein said curtain is made of cloth, and said curtain includes a through hole separately corresponding to the bottom of said control reel module and said hanging reel for passing said first pulling cord, said second pulling cord and said third pulling cord.
