Abstract
The present invention discloses a window blind within a multi-pane window. A window blind disposed between first and second panes includes a plurality of slats. Raise/lower and tilt lines are coupled to the slats. A carriage housing is disposed between the panes proximate a side edge thereof. A tilt strip is disposed within the carriage housing and coupled to the tilt lines. An inner carriage disposed within the carriage housing includes an upper portion coupled to the raise/lower lines to actuate raising and lowering the slats, and a lower portion coupled to the tilt strip to actuate tilting the slats. An external carriage is adjacent the exterior surface and aligned with and magnetically coupled to the inner carriage. The external carriage is linearly movable to move the inner carriage. A method of adjusting a window blind within a multi-pane window is also disclosed.
