DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0015] Referring to FIGS. 1 to 4, the window blinds include a top box and a bottom rail. Multiple slats are located between the top box and the bottom rail. The slats are located between multiple ropes 11 which are respectively located at the front side of the slats and at the rear side of the slats. The ropes 11 are connected to a control unit 20 received in the top box.

[0016] Each rope 11 is received in a sleeve 12, and the sleeves 12 are made by knitting laces in this embodiment. At least one support wire 121 is connected between the sleeves 12 located on the front and rear sides of the slats. The slats are supported on the at least one support wire 121. The at least one support wire 121 is controlled by the control unit 20 to lift or lower the slats.

[0017] The top box includes holes 21 defined through the bottom thereof, and each hole 21 has a securing member 22 engaged therewith. The securing members 22 each are a T-shaped member with three open ends and a top opening. The three open ends and the top opening communicate with each other. The rope 11 extends through the securing member 22 corresponding thereto, and extends through the top opening so as to be connected with the control unit 20. The sleeve 12 is mounted and secured on outside of the securing member 22 corresponding thereto as shown in FIG. 4.

[0018] The ropes 11 are hidden in the sleeves 12 which look decoratively beautiful in a room. The at least one support wire 121 is sewed to the sleeves 12, and the slats are supported on the at least one support wire 121. The distance between any of the two adjacent at least one support wires 121 is short, so that even when the rope 11 and the sleeve 12 are pulled by children, only the distance between any of the two adjacent at least one support wires 121 is pulled, the short length of the rope 11 and the sleeve 12 does not harm to the children.

[0019] While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
