How a Small Control Moves Every Slat
The tilt rod is connected to a mechanism inside the blind’s top rail. Turning it rotates a gear, which turns a long shaft running across the rail. The shaft’s motion is carried to the slats by narrow cord ladders spaced along the blind.
Each ladder has two vertical cords joined by short crosspieces. A slat rests on each crosspiece, like a rung on a flexible ladder. When the mechanism twists the cords, one side of each ladder rises as the other falls. Because every slat sits on the same set of moving rungs, they tilt together.
Why the Slats Stay in Step
The key is that the mechanism moves the ladders, not each slat separately. The top rail distributes one turning motion across the blind, while the ladders transfer it to slats at many heights. This keeps the slats coordinated without needing a separate control for each one.
The angle changes how much light passes through and whether someone can see through the blind. Turn the slats toward one another and their edges overlap; turn them the opposite way and gaps open. The mechanism’s small rotation therefore changes the whole window’s balance of light and privacy.
