Abstract: A hanger device includes a pin fixed to a shade of a window blind. The pin includes an end extending away from the shade in a thickness direction. A hanger body includes a slot having first and second sections spaced in a vertical direction perpendicular to the thickness direction. The first section is in communication with and above the second section. A width of the first section in a width direction perpendicular to the thickness and vertical directions is larger than a diameter of the pin, which, in turn, is not smaller than a width of the second section. The pin is extended through the first section. The hanger is moved upward with the pin moving from the first section into and tightly engaged with the second section. A slide is coupled to an upper end of the hanger body and slideably received in a head rail of the window shade.
