Abstract
A window operator for control of the opening and closing of a window sash mounted with a window frame. The window operator may include a drive mechanism, a drive element movable on a rectilinear path by the drive mechanism, and a first linkage of which a primary point of rotation is fixed relative to the drive mechanism. Additionally, the window operator may include a first mounting for attachment of the first linkage to the window sash at a first position, a second linkage connected to the drive element, and a second mounting for attachment of the second linkage to the window sash at a second position. Here, the second position may be closer to the hinged side of the window sash relative to the window frame than the first position. The window operator may further include an interconnection linkage pivotally coupling the first and second linkages.
