  • Handle structure and assembly for bottom rail of window shading
    Patent number: 11199048
    Abstract: A pivotable handle for an architectural covering is provided. The handle (400) includes first and second members (408,410) pivotably connected together at a hinge assembly (460). The first member (408) may be operable to connect the handle (400) to a movable rail (512). The second member (410) pivots between stored and use positions. In a stored position, the second member (410) may extend adjacent the first member (408). In a use position, the second member (410) may be pivoted away from the first member (408) to extend the movable rail (512) across an architectural structure. The handle includes a biasing member (470) operable to bias the second member (410) towards the first member (408).

  • Pull cord for coverings for architectural openings and method of making same
    Publication number: 20030085004
    Abstract: A method of manufacturing a control cord for use in a covering for architectural openings includes the steps of providing spools of high tensile strength and low abrasion characteristic yarns, tensioning the yarns and winding the yarns under tension on bobbins, placing the bobbins in a braiding apparatus and making an eight-carrier braid from the yarns on the bobbins, and passing the braided cord through a treatment apparatus where a urethane coating is applied to the yarns and heat cured.
