  • Patent number: 9476253
    Abstract: An automatic cord collector of a window blind has a housing, a holding assembly mounted inside the housing with one end of each pull cord fastened therein, an adjusting assembly mounted inside the housing and extending into the holding assembly, and a spiral spring mounted inside the holding assembly. The adjusting assembly can be turned for the holding assembly to be unlocked or rotatable such that the spiral spring automatically drives the holding assembly to rotate for winding and collecting the pull cords. Users can pull the pull cords to rotate the holding assembly. When the pull cords need to be positioned, the adjusting assembly can be turned to abut against the holding assembly so that the holding assembly is unable to be rotated and the pull cords can be positioned. Accordingly, the automatic cord collector ensures operational convenience, cord safety and accident prevention.
