Window blind with controlling axle

Abstract

A window blind includes an operation system, a slat system, and a controlling axle. The operation system includes a plurality of slat cords downwardly supported by a top support. The slat system includes a plurality of slat sets suspendedly supported by the slat cords respectively, wherein each of the slat sets includes a plurality of blind slats horizontally, spacedly and suspendedly supported through the slat cords. The controlling axle is rotatably supported along the top support, wherein the controlling axle includes a controlling shaft and a plurality of controlling units which are coaxially coupled at the controlling shaft and are coupled with the slat cords respectively. When the controlling shaft is driven to rotate, the blind slats are asynchronously and horizontally shifted in responsive to the controlling units so as to selectively adjust a light gap between every two the neighboring blind slats.
