Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 151 words
A window blind control apparatus in combination with a window blind unit wherein the window blind unit includes a series of parallel slats pivotally mounted from an opened horizontal position to a closed horizontal position, the window blind control apparatus comprising, a housing including a reversing electric motor, said housing fixedly mounted relative to said window blind unit laterally displaced from the slats, and a photo-cell means responsive to available light mounted between the window blind unit and a window housing to a vertical support surface adjacent the window blind unit, and wherein the photo-electric cell means is remotely mounted relative to the housing for actuation of the motor, and the motor including an upper drive member for operative association with a window blind unit and a lower drive operatively associated with a window blind control rod, wherein the upper drive & the lower drive are axially aligned through the motor.
Claim 2
Dependent Claim 151 words
A window blind control apparatus in combination with a window blind unit wherein the window blind unit includes a series of parallel slats pivotally mounted from an opened horizontal position to a closed horizontal position, the window blind control apparatus comprising, a housing including a reversing electric motor, said housing fixedly mounted relative to said window blind unit laterally displaced from the slats, and a photo-cell means responsive to available light mounted between the window blind unit and a window housing to a vertical support surface adjacent the window blind unit, and wherein the photo-electric cell means is remotely mounted relative to the housing for actuation of the motor, and the motor including an upper drive member for operative association with a window blind unit and a lower drive operatively associated with a window blind control rod, wherein the upper drive & the lower drive are axially aligned through the motor.
Claim 3
Dependent Claim 49 words
A window blind control apparatus as set forth in claim 1 wherein the photo-cell means comprises a photo-cell including a shade member pivotally mounted relative to the photo-cell, the shade member including a handle extending outwardly of the shade to enable rotation of the shade to overlie the photo-cell.
Claim 4
Dependent Claim 37 words
A window blind control apparatus as set forth in claim 2 further including a manually displaceable slide switch mounted through the forward wall of the housing to selectively pivot the slats to an open or closed position.
Claim 5
Dependent Claim 46 words
A window blind control apparatus as set forth in claim 3 further including a plurality of mounting apertures formed through a rear wall of the housing for securement of the housing to a vertical support surface adjacent the window blind unit or to window blind itself.
Claim 6
Dependent Claim 39 words
A window blind control apparatus as set forth in claim 4 further including an electric motor adjustment stop means operatively associated with an electric motor for controlling the number of revolutions of the motor during actuation of the motor.
