Window blind

A window blind switchable between a first state and a second state allowing different amount of light passing through the window blind, the window blind comprising:

• an upper rail;
• a lower rail, situated below the upper rail;
• a deflecting mechanism, disposed on the upper rail;
• a ladder tape, connected to the deflecting mechanism and comprising:
• a first longitudinal cord, having plural first positions thereon spaced a predetermined interval apart from each other;
• a second longitudinal cord, substantially parallel to and spaced from the first longitudinal cord, the second longitudinal cord having plural second positions and plural third positions thereon, wherein when the window blind is in the first state, the second positions are respectively at substantially the same height as the first positions, and the third positions are respectively adjacent to the second positions;
• plural bearers, situated between the first longitudinal cord and the second longitudinal cord, each of the bearers having one end connected to a respective one of the first positions on the first longitudinal cord, and another end connected to a respective one of the second positions on the second longitudinal cord;
• and
• plural limiting members, each of the limiting members having a first end disposed on a respective one of the third positions on the second longitudinal cord and a second end opposing to the first end, the limiting members comprising a first limiting member and a second limiting member adjacent to the first limiting member;
• and
• plural slats, situated between the upper rail and the lower rail and respectively supported by the bearers, wherein a first end of the first longitudinal cord and a first end of the second longitudinal cord are connected to the deflecting mechanism for suspending the ladder tape below the upper rail, and a second end of the first longitudinal cord and a second end of the second longitudinal cord are connected to the lower rail;
• the deflecting mechanism is configured to drive the first longitudinal cord and the second longitudinal cord to move in opposite directions, by which the bearers are tilted along with movements of the first longitudinal cord and the second longitudinal cord so that the slats supported thereby are concurrently tilted, making the window blind switched from the first state in which the slats are in horizontal positions to the second state in which the slats are tilted as a lateral edge of each slat keeps a minimum distance from another lateral edge of the neighboring slat;
• wherein the bearers comprise a first bearer and a second bearer adjacent to the first bearer;
• the slats comprise a first slat and a second slat adjacent to the first slat which are supported by the first bearer and the second bearer respectively, and the first slat has a first through hole adjacent to the second longitudinal cord;
• the first limiting member comprises a first slat-through portion and a first linking loop, wherein the first slat-through portion is located between the first end and the second end of the first limiting member and passes through the first through hole of the first slat, and the second end of the first limiting member is located at the first linking loop;
• the second limiting member passes through the first linking loop.
