Abstract:
1. A window comprising: a housing defining a first opening and a second opening, and comprising a first end, a second end, a first sidewall, and a second sidewall, the first and second sidewalls extending between the first end and the second end; a first window shade comprising a fixed end and a free end, the first window shade being disposed inside the housing, the fixed end extending between the first and second sidewalls and being fixed proximate to the first end of the housing, the free end extending between the first and second sidewalls and being movable along the first and second sidewalls between a retracted position, where the passage of light through the first and second openings is unobstructed by said first window shade, and an extended position, where the passage of light through the first and second openings is obstructed by said first window shade; a second window shade comprising a fixed end and a free end, the second window shade being disposed inside the housing, the fixed end extending between the first and second sidewalls and being fixed proximate to the first end of the housing, the free end extending between the first and second sidewalls and being movable along the first and second sidewalls between a retracted position, where the passage of light through the first and second openings is unobstructed by the second window shade, and an extended position, where the passage of light through the first and second openings is obstructed by the second window shade; a first motor secured proximate to the first end of the housing; a second motor secured proximate to the first end of the housing; a first rotation means rotatably secured proximate to the first end of the housing; a second rotation means rotatably secured proximate to the first end of the housing; a first rotatable shaft comprising a first end and a second end, the first rotatable shaft being rotatably secured proximate to the second end of the housing and disposed between the first and second sidewalls; a second rotatable shaft comprising a first end and a second end, the second rotatable shaft being rotatably secured proximate to the second end of the housing and disposed between the first and second sidewalls; first rotation coupling means extending along the first sidewall between the first motor and the first end of the second rotatable shaft to drive the second rotatable shaft in response to operation of the first motor; second rotation coupling means extending along the second sidewall between the second end of the second rotatable shaft and the second rotation means to drive the second rotation means in response to operation of the first motor; third rotation coupling means extending along the second sidewall between the second motor and the second end of the first rotatable shaft to drive the first rotatable shaft in response to operation of the second motor; fourth rotation coupling means extending along the first sidewall between the first end of the first rotatable shaft and the first rotation means to drive the first rotation means in response to operation of the second motor; means for coupling the free end of the first window shade between the third and fourth rotation coupling means so that the first window shade is retracted or extended in response to operation of the second motor; and means for coupling the free end of the second window shade between the first and second rotation coupling means so that the second window shade is retracted or extended in response to operation of the first motor.
