The present disclosure provides advantageous window covering mechanisms, systems and apparatus that permit multiple window shades (e.g., a pair of window shades) or blinds to be operated from a single headrail. The window covering mechanisms permit the multiple window shades to be operated by a single control mechanism, e.g., a single operating cord. A motion translation mechanism is generally for operation of the multiple shades. The mechanism may include oppositely directed windings of first and second lift cords relative to a rotatable member. The disclosed systems may be used with shades (e.g., Roman shades) and blinds such that interaction with a single cord or other control mechanism functions to simultaneously reposition first and second shade or blind panels. The first and second shade or blind panels may advantageously be selected to provide varying levels of light blocking and/or privacy properties. |
