Two-way elevation curtain structure

Abstract

The present invention provides a two-way elevating curtain structure, which uses a fixed curtain rod with several pull strings to assemble the cord fabric. A control structure is used to elevate the curtains up and down. The control structure includes a first/second roll-up cord shaft, which is placed on the fixed curtain rod to help the first/second controlling components on both sides of the fixed curtain rod operate the first/second roll-up cord shaft independently. The curtain is made to elevate more smoothly.

1 . A two-way elevating curtain structure, comprising: 
 a fixed curtain rod being comprised of a first/second controlling component using pull strings on both sides thereof so as to move cord fabric up and down, and a control structure, said control structure being comprised of a first/second roll-up cord shaft placed on a shaft inside a fixed curtain rod, making one end of the first/second roll-up cord shaft connect to the first/second controlling components, controlling cords of the first/second controlling components being pulled down, the controlled component to the first/second roll-up cord shaft in driven in clockwise and counter-clockwise directions.    
     
     
         2 . The structure defined in  claim 1 , wherein the first roll-up cord shaft is wrapped by the pull strings, one end of the pull strings going through the fixed curtain rod and through the top of the cord fabric and the cloth cover connected to the bottom, and wherein the second roll-up cord shaft is wrapped around by the pull strings, one end of the pull strings going through the fixed curtain rod and being secured to the top of the cord fabric.  
     
     
         3 . The structure defined in  claim 1 , wherein the first/second controlling component is placed on both sides of the surface of the fixed curtain rod, said first/second controlling component being placed on the surface of the fixed curtain rod in 90-degree angle, one end of the first/second roll-up cord shaft being used to connect to the bevel gear and locked in with the bevel gear of the first/second controlling components.  
     
     
         4 . The structure defined in  claim 1 , wherein said cord fabric is a Roman curtain.  
     
     
         5 . The structure defined in  claim 1 , further comprising: 
 sets of pull strings added upon the first/second roll-up cord shaft and connected to the top, the cloth cover and bottom of the cord fabric.
