Width-adjustable curtain track

Abstract

A width-adjustable curtain track includes a track assembly and a connection device to link to the track assembly, which, as well as connection device, can be undrawn or folded in the axial direction, to enable a curtain cloth that is attached on the connection device to extended or folded followed the connection device. Owing to the adjustable width function of the track assembly, the invention is applicable to various window frames for adjusting to required widths to further increase the convenience of curtain usage.

1 . A width-adjustable curtain track, wherein a curtain cloth to be pulled by a plurality of operating cords with different functions, enabling the curtain cloth to form in a folded or extended status; the curtain track comprising: 
 a track assembly with an inner track and an outer track, which is set outside the inner track, so that the inner track and the outer track can be undrawn or folded in an axial direction and are able to adjust to required widths thereof; and    a connection device with a plurality of connecting joints link to each others thereof with a revolvable way; in addition, the top of the connecting joints set a mechanism to link to the inner and the outer tracks, when the track assembly adjusts the widths of the inner and the outer tracks, the connection device is simultaneously affected to stretch and or fold the curtain cloth.    
     
     
         2 . The width-adjustable curtain track of  claim 1 , wherein a plurality of connecting joints are linked to two sets of connection components in the opposite direction and crisscross arranged to each other thereof.  
     
     
         3 . The width-adjustable curtain track of  claim 1 , wherein the curtain cloth can be torn off from a plurality of connecting joints.  
     
     
         4 . The width-adjustable curtain track of  claim 1 , wherein the top of the curtain cloth is attached to a plurality of connecting joints through creasing the curtain cloth, which fully accommodate to the width of the track assembly thereby pulling and folding the curtain cloth, in addition, maintain the width consistency between the curtain cloth and the track assembly.
