Pleated curtain glider unit

Abstract

A glider unit for pleated curtain comprises a sliding carriage and a fastener. The sliding carriage has a female snap-fit portion provided at its bottom for engaging with the fastener. The fastener has a combining section for fixing with a curtain fabric. The outer edge of the female snap-fit portion is formed as an arc segment, whereby the curtain fabric can be compliant with the arc segment so as to form regularly pleated pattern and smooth fabric surface during the closing of the curtain. Two pulleys pivotally coupled by a shaft are respectively mounted at both sides of each sliding carriage for moving on a curtain track. A plurality of balls are disposed between each pulley and the shaft so as to facilitate the rolling of each pulley without much application of force, so that opening and closing of the curtain can be accomplished in less laborious effort required.

What is claimed is: 
     
         1 . A glider unit for pleated curtain, comprising:
 a sliding carriage having two pulleys provided at both sides thereof respectively, said two pulleys being pivotally coupled with each other by a shaft; a plurality of balls being disposed between each said pulley and said shaft; a female snap-fit portion being provided at the bottom of said sliding carriage and an arc segment being formed on the outer peripheral edge of said female snap-fit portion; a groove being provided in said female snap-fit portion, said groove having an opening with wider dimension at outside and smaller dimension at inside being provided at its bottom, a circular bore in conjunction with said opening being also provided; two stop portions being respectively provided at both sides of said opening;   a fastener having a male snap-fit portion for engaging with said female snap-fit portion of said sliding carriage, said male snap-fit portion having a head portion for fitting into said groove and a neck portion with a smaller diameter right below said head portion for fitting into said circular bore after passing through said opening; and a combining element for fixing with a curtain fabric being provided at one end of said male snap-fit portion.   
     
     
         2 . The glider unit for pleated curtain as claimed in  claim 1 , wherein said combining element is a buckle ring for engaging with a corresponding buckle plug of said curtain fabric. 
     
     
         3 . The glider unit for pleated curtain as claimed in  claim 1 , wherein said combining element is a C-shape socket for engaging with a corresponding buckle plug of said curtain fabric.
