Abstract
The present invention discloses a blind slat positioning device and a window blind thereof. The positioning device can fix the slat at any height at which the slat is pulled down. The positioning device includes a turning seat which is provided at least with an overbend element for a pull cord to wrap around. The overbend element includes at least a ridge, resulting an effect that the slat stops at the height at which the slat is pulled down, with the aid of gravity.

A blind slat positioning device, comprising
- a turning seat, which provides for a pull cord to turn and cross over, with the pull cord being formed by twisting fibers, and the cross section of a thread body varying in shape, with a bottom of the turning seat including a base plate, and an overbend element in a shape of long rod for the thread of pull cord to climb over and change direction, with the overbend element being combined inside the turning seat, and a longitudinal line of the overbend element being parallel to the base plate and transversely perpendicular to a running direction of the pull cord, and with the overbend element further including
- a rod body, two ends of which being fixed at a three-dimensional angle;
- and
- a long ridge, which is disposed on a longitudinal surface of the rod body, and is disposed on a longitudinal location at which the overbend section of the thread of pull cord passes through tangentially.
