  • Patent number: 4793396
    Abstract: The invention relates to window coverings and in particular to a device for mounting fabric covering to a headrail. The device includes a cord guide holder having a body received in and supported by the headrail. The holder has a flexibly attached tongue which extends from the headrail. A clip attaches to the fabric by receiving the fabric over a torturous path. The tongue mounts to the clip so the flexible connection permits changing the orientation of the clip with respect to the holder body in a vertical, horizontal and twisting plane.
