  • Patent number: 7533711
    Abstract: The present invention is a method of attaching a ring member to a cord using a minimum of steps. The method includes the steps of providing a hobble cord having opposite first and second ends and a plurality of loops. The loops of the cord are preferably preformed onto the cord and are integral thereto. Each loop formed on the cord has a loop opening dimensioned to receive one end of the cord. The first end of the cord is first threaded through the ring and the ring is then positioned to sit adjacent one of the loops between the loop and the first end of the hobble cord. The first end of the hobble cord is then threaded through the opening of the loop. The ring is then firmly secured to the cord by pulling the cord all the way through the loop. The steps may be repeated to attach more rings to the cord in succession.

  • Publication number: 20070000618
    Abstract: An improved Roman blind assembly is disclosed. The Roman blind assembly consists of a fabric screen having opposite first and second sides and opposite first and second ends. A plurality of parallel roman bars are mounted horizontally to the first side of the fabric screen between the first and second ends of the screen. A lowermost roman bar is mounted to the screen near the first end of the screen and a pair of parallel support cords are mounted to the lowermost roman bar. A roller clutch assembly is mounted to the first side of the fabric screen adjacent the second end of the screen. The support cords are coupled to the clutch assembly and the clutch assembly is adapted to raise and lower the cords. Each of the support cords pass through an elongated opening in the screen, said openings positioned adjacent the second end of the screen. After exiting the openings, the cords pass along the second side of the screen. Each cord is slidingly attached to each roman bar.

  • Patent number: 7124801
    Abstract: An improved Roman blind assembly is disclosed. The Roman blind assembly consists of a fabric screen mounted to a pair of suspension cords and a pair of pull cords. Each of the suspension cords consists of an elongated flexible cord having a plurality of loops formed along a length of the cord, each loop being a loop of flexible cord defining a loop opening. The blind assembly also includes a plurality of elongated mounting elements mounted to the fabric screen to form a plurality of parallel folds, each of said mounting element being mounted to one of the loops of each suspension cord. Finally, the blind assembly also includes a drawing mechanism for pulling up the fabric screen by drawing up the pull cords.
