Therefore, the cord goes into the locking slot quickly and is clamped by edges of the locking slot while a kid is trying to pull the cord out of the slats. A diameter of the cord is preferred to be greater than or equal to a width of the locking slot. The cord passes through the headrail and the bores of the slats, and is fastened to the bottom rail. The locking slot has an open end and a closed end, and the open end of the locking slot is connected to the bore. The slats are arranged between the headrail and the bottom rail, and each slat has at least a bore and at least a locking slot. In order to achieve the objective of the present invention, a window blind includes a headrail, a bottom rail, a plurality of slats, and at least a cord is invented. In view of the above, the primary objective of the present invention is to provide a window blind, which makes the kids difficult to pull the lift section out of the slats.

It is because that the lift sections 204 are free to move in the bores 142, so that the kid may pull them out easily and cause a tragedy. When the bottom rail 12 is lowered to the lowest position, it has a risk to let a kid be strangled in case he/she pulls the lift sections 204 between the slats 14 out, and get the lift sections 204 around his/her neck (seeing FIG. Pulling or releasing the control sections 202 may lift or lower the bottom rail 12 to retract or extend the slats 14. The control sections 202 extend out of the headrail 10 to be operated by user. The lift sections 204 run over the lifting control devices 18, then pass through the bores 142 of the slats 14 in sequence, and finally are fastened to the bottom rail 12.

The control section 202 connects to the lift section 204. Each cord 20 has a control section 202 and a lift section 204. The lifting control devices 18 are received in the headrail 10. The transmission unit 16 has two lifting control devices 18 and two cords 20. Each slat 14 has two elongated bores 142. The slats 14 are parallel, and are arranged between the headrail 10 and the bottom rail 12. 1 shows a conventional window blind 1, including a headrail 10, a bottom rail 12, a plurality of slats 14, and a transmission unit 16. The present invention relates to a covering of an opening of a building, and more particularly to a window blind with safety slats.ДЇIG.
