Abstract
An actuator device is provided for use in a view-through window covering having a plurality of cells. The actuator device includes at least one cooperating pair of control members including a first control member that engages an upper portion of each cell and a second control member that engages a lower portion of each cell. The cooperating pair of control members are engaged with the cells along a plane parallel to the plane of the window covering, whereby relative movement of the control members modifies the size of the space between the cells. The actuator device may also include an actuator mechanism selectively operable to create opposite movement of the first and second control members. A guide member may also be provided to transition the first and second control members from being aligned substantially perpendicular to the window covering plane to being aligned substantially parallel with the window covering plane.
