What is a Mini Blind?
The long horizontal slats are held one above the other by the rungs of ladder cords shaped like a ladder. The lower ends of the legs of the ladder cords are secured to the long rail under the slats. Their upper ends are attached to the drive rod in the housing, the elongated box above the slats. As the drive rod rotates, one leg of each ladder cord moves up while the other moves down, causing the angle of the slats to change. In one design, this rotation is achieved by pushing up or pulling down on a long handle called a tilt wand connected to the drive rod by a lever. Lift cords along the ladder cords are also attached to the rail. They pass through holes in the slats and into the housing above, where they go over pulleys, combine and exit through the cord lock. For safety it’s important that the lock always work. A downward pull on the main lift cord raises the slats by the cords pulling up the rail below the slats. The cord lock holds the main lift cord to keep the slats up until the cord is pulled to release the lock. The safety lock made the cord lock easier to use.
