Interlocking ring curtain liner and curtain systems thereof

Abstract

Improved curtain liners comprising a plurality of fabric loops for convenient hanging on a curtain rod through clip hanging rings, with the liner panel, fabric loops, and clip hanging rings all hidden from the view of front curtain, and the curtain systems comprising such improved curtain liners are disclosed.

What is claimed is: 
     
         1 . A curtain liner comprising: a liner panel having a top horizontal hem attached with a plurality of vertical fabric loops, each fabric loop capable of interlocking with a clip hanging ring, which clip hanging ring can click-open from or close onto a curtain rod, wherein the liner panel can fit snugly behind a curtain hanging on the same curtain rod with a hanging means and open or fold smoothly along with the curtain, when the hanging rings slide along the curtain rod. 
     
     
         2 . The curtain liner of  claim 1 , wherein the liner panel is substantially rectangular-shaped having a bottom horizontal hem at substantially the same height as, or slightly higher than, the bottom hem of the front curtain when both the liner and the front curtain are hung on the curtain rod. 
     
     
         3 . The curtain liner of  claim 1 , wherein the plurality of the vertical fabric loops is the same as that of the hanging means on the front curtain. 
     
     
         4 . The curtain liner of  claim 3 , wherein the plurality of the vertical fabric loops is eight so that the curtain liner fits with an 8-grommet curtain. 
     
     
         5 . The curtain liner of  claim 1 , wherein the spacing between each pair of adjacent loops is determined based on the spacing of corresponding pair of adjacent hanging means on the front curtain such that the clip hanging rings can smoothly slide along the curtain rod along with the hanging means of the front curtain. 
     
     
         6 . The curtain liner of  claim 1 , wherein the plurality of the vertical fabric loops is eight so that the curtain liner fits with an 8-grommet curtain. 
     
     
         7 . The curtain liner of  claim 1 , wherein the dimensions of the liner panel and of the fabric loops on the top hem of the liner panel are determined based on the size and dimensions of the front curtain such that the liner panel, the fabric loops, and the clip hanging rings are substantially or completely hidden from view of the front curtain. 
     
     
         8 . The curtain liner of  claim 7 , wherein the dimensions of the liner panel and of the fabric loops on the top hem of the liner panel are substantially as described in the specification and  FIG. 1, 2, 3 , or  7 , or a combination thereof. 
     
     
         9 . The curtain liner of  claim 1 , wherein the clip hanging ring has an internal diameter in the range of 1″ to 2.75″. 
     
     
         10 . A curtain system comprising a curtain liner of  claim 1 , a front curtain comprising a curtain panel having a top hem and a bottom hem, with a plurality of hanging means aligned horizontally close to the top hem, and a curtain rod, wherein the curtain liner and the front curtain can hang on the curtain rod together in an aligned way such that the curtain liner is hidden from view of the front curtain. 
     
     
         11 . The curtain system of  claim 10 , where the hanging means of the front curtain comprises grommets with diameter larger than the diameter of the curtain rod. 
     
     
         12 . The curtain system of  claim 10 , which is a window curtain system, window drape system, or shower curtain system. 
     
     
         13 . The curtain system of  claim 10 , which is an 8-grommet window curtain system. 
     
     
         14 . The curtain system of  claim 10 , which is an 8-grommet 84″ window curtain system. 
     
     
         15 . The curtain system of  claim 13 , wherein the width of the 8-grommet window curtain is between 50″ and 60″, and length is of any home textile industry standard length in the U.S. market. 
     
     
         16 . A method of preparing a curtain liner of  claim 1 , comprising making a plurality of fabric loops, (2) sewing or stitching the fabric loops onto a liner panel with spacing between adjacent loops pre-determined according to spacing of hanging means of the curtain to which the curtain liner matches, and (3) optionally selecting clip hanging rings for hanging the curtain liner onto curtain rod behind the curtain. 
     
     
         17 . The method of  claim 16 , wherein the making of fabric loops comprises the steps of: (a) cutting a fabric into a substantially rectangular shape (e.g., in a size of 3″ W×4.5″ L); (b) folding and sewing the fabric into a double layer ribbon (e.g., in a size of 1″ W×4.5″ L); and (c) folding the ribbon at the mid-point to form a four-layer loop (e.g., in a size of 1″ W×2.25″ L). 
     
     
         18 . The method of  claim 16 , wherein the method of sewing or stitching the fabric loops comprises: (d) providing a curtain liner panel in substantially rectangular shape having a top hem and a bottom hem, wherein the top hem comprises a bottom line and a top line; (e) sewing or stitching the open end of the four-layer loop made in step (c) of  claim 17  to the bottom line of the curtain liner top hem; and (f) sewing or stitching the loop onto the top line of the curtain liner top hem; wherein the step (e) and step (f) fasten the 4-layer loop onto the top hem of the curtain liner permanently and firmly.
