Claim 5:
6. A method of assembling the slats of the window blind of claim 1, comprising steps of:
a) mounting the plurality of slats on the transverse portions of the two ladder ropes; and
b) inlaying the segment of each third ring portion into the slot of the corresponding slat, and inlaying the segment to the corresponding through hole of the corresponding slat through the corresponding slot of the corresponding slat, so that each third ring portion of the ladder rope is mounted around the front edge of the corresponding slat,
wherein each slot extends from the front edge of the corresponding slat to be communicated with the corresponding through hole,
wherein each slot has a first extending segment and a second extending segment that is perpendicular to the first extending segment, the first extending segment extending from the front edge of the corresponding slat in a width direction of the corresponding slat to a rear edge of the corresponding slat, and the second extending segment extending from one end of the first extending segment in a length direction of the corresponding slat to the through hole and is communicated with the corresponding through hole,
wherein each through hole has a round cross-section, and each through hole is located between the front edge of the corresponding slat and the second extending segment of the corresponding slot, so that each through hole is tangent to the corresponding second extending segment of the corresponding slot, a length of the first extending segment of each slot in the width direction of the corresponding slat being formed of a diameter of the corresponding through hole and a distance between the corresponding through hole and the front edge of the corresponding slat in the width direction of the corresponding slat,
wherein one end of the segment of each third ring portion is fixed to the one of said ladder ropes at a first position above a top surface of the corresponding slat, and the other end of the segment of each third ring portion passes through the corresponding through hole from one side of the corresponding slat to another side of the corresponding slat, extends, in the width direction of the corresponding slat, through a space between the corresponding slat and the corresponding transverse portion, and then fixed to the one of said ladder ropes at a second position spaced apart from the first position and below the top surface of the corresponding slat when the corresponding slat is not tilted and is perpendicular to the one of said ladder ropes, and
wherein each first ring portion is fixed to the one of said ladder ropes at a third position above the top surface of the corresponding slat that is closest thereto when the corresponding slat is not tilted and is perpendicular to the one of said ladder ropes, and above the first position of the corresponding third ring portion that is closest thereto and passes through the corresponding slat.
