ABSTRACT:
A powered angling rod readily connected in combination with a new or existing window Venetian blind unit, replacing the original manual-only angling rod, wherein, the window blind includes a head rail and parallel slats pivotally mounted. The powered angling rod comprises an elongated small size tubular main housing preferably closely visually resembling current manual-only control rods. Preferably a vertically adjustable hook structure is provided for readily connecting the powered angling rod to rotatable drive shafts protruding from the head rail, which vary widely in length between manufacturers of Venetian/mini-blinds. The adjustable hook structure also serves as a rotating power shaft for tilt angling the blind slats and is coupled to a motor shaft arrangement for rotational power. The motor is partially confined within the upper terminal end of the main housing. An anti-rotation structure readily connects between the main housing and a stationary item such as the head rail to render the motor and main housing stationary while leaving the motor shaft arrangement free to rotate the hook structure to alter the position of the blind slats. Within the main housing is micro-powered, power saving electronic control circuitry for automatic actuation of the motor via light or temperature detection sensors, and manual control via push switch, or infrared remote control. A battery power source is also within the main housing. The powered angling rod readily attaches to virtually any Venetian/mini-blind suitable to use a manual-only rod.
