System for pivoting a blind slat

摘要

Systems and methods for pivoting a blind slat by manipulating one or more tilt cords of a set of blind slats to achieve superior blind closure. More particularly, the present invention relates to a window covering having a blind slat that is rotated clockwise or counter-clockwise by rotating a driving mechanism that is positioned in a horizontal orientation. The present invention further relates to a window covering system that achieves tilting of blind slats without requiring the traditional tilting components of standard Venetian-type blinds.

主权项

1. A system for rotating a blind slat, the system comprising:
a plate; a blind slat suspended below the plate; a first tilt cord having a first end, a second end, and a middle portion of the first tilt cord extending therebetween, the first end of the first tilt cord being attached to a first cord retention device, the second end of the first tilt cord being attached to a proximal portion of the blind slat, and the middle portion of the first tilt cord passing through the plate, wherein the first end of the first tilt cord is adjustable within the first cord retention device to change a distance between the second end of the first tilt cord and the plate to at least one of raise and lower the proximal portion of the blind slat with respect to the plate; and a second tilt cord having a first end, a second end, and a middle portion of the second tilt cord extending therebetween, the first end of the second tilt cord being attached to a second cord retention device, the second end of the second tilt cord being attached to a distal portion of the blind slat, and the middle portion of the second tilt cord passing through the plate, wherein the first end of the second tilt cord is adjustable within the second cord retention device to change a distance between the second end of the second tilt cord and the plate to at least one of raise and lower the distal portion of the blind slat with respect to the plate.
