Abstract: A window blind includes top and bottom beams, and many slats disposed therebetween. The top beam has two opposite lateral holes. The window blind further includes a slat folding transmission device having a cord rolling member disposed in the top beam, and two opposite lift transmission cords passing through the lateral holes of the lateral plates of the top beam respectively. Two ends of each lift transmission cord are connected with the bottom beam and the cord rolling member respectively, so that the two lift transmission cords can pull the bottom beam simultaneously when being rolled by the cord rolling member, thereby moving the bottom beam upwardly to fold up the slats. Therefore, the slats of the window blind of the invention need no processing and keep complete in structure, thereby providing good effect of blocking out the light when being adjusted to the inclined condition.

Abstract: A window body positioning mechanism of a non pull cord window blind includes two first transmission wheels, two transmission cords respectively connected with one ends thereof to the first transmission wheels, two second transmission wheels meshed together and respectively meshed with the first transmission wheels, a coil spring connecting the two second transmission wheels and selectively wound round one second transmission wheel, and two resistance units each including a one-way pawl and a resistance wheel wound by one respective transmission cord and meshed with the one-way pawl. Thus, when extending out or receiving the blind body, the friction resistance between the resistance wheels and the transmission cords and the engagement relationship between the resistance wheels and the respective one-way pawls help achieve excellent blind body positioning effects.
