Abstract
The present application pertains to a system for adjusting the height of a covering, such as window or a wall covering formed of two or more covering segments that are axially aligned. The system includes a link that selectively transmits rotation between two adjacent coverage thereby allowing the two coverings to be controlled, e.g., raised or lowered, simultaneously. The link includes a clutch that allows one of the segments to be rotated with respect to the other so that the bottom end of one of the coverings can be adjusted and aligned horizontally independently of the other. Optionally, the clutch includes an internal member that provides a mechanical advantage while the one covering is adjusted.
