Head rail-mounted actuator for window covering

A window covering with actuator, comprising:

• a roll up shade including a head rail, a tube rotatably disposed therein, and a shade-type window covering engaged with the tube for moving the window covering between a raised configuration and a lowered configuration when the tube is rotated;
• an electric motor in the head rail;
• a collar coupling operably engaged with the motor to engage the motor with the tube for rotating the tube;
• at least one primary dc battery connected to the motor in the head rail;
• a control signal generator for generating a control signal;
• and
• an electronic circuit electrically connected to the control signal generator and the battery for processing the control signal to cause the battery to energize the motor to move the tube, the electronic circuit having at least one of:
• a pulse mode for energizing the motor in pulses, and a continuous mode for continuously energizing the motor.

A window covering with actuator, comprising:

• a shade including a head rail, a tube rotatably disposed therein, and a window covering engaged with the tube for moving the window covering between a raised configuration and a lowered configuration when the tube is rotated;
• an electric motor;
• a coupling operably engaged with the motor to engage the motor with the tube for rotating the tube;
• at least one dc battery, the at least one battery being the sole source of energy associated with the window covering;
• a control signal generator for generating a control signal;
• and
• an electronic circuit electrically connected to the control signal generator and the battery for processing the control signal to cause the at least one battery to energize the motor to move the tube, the electronic circuit having at least one of:
• a pulse mode for energizing the motor in pulses, and a continuous mode for continuously energizing the motor.

A powered shade assembly, comprising:

• a shade including a head rail, a tube rotatably disposed therein, and a shade-type window covering engaged with the tube for moving the window covering between a raised configuration and a lowered configuration when the tube is rotated;
• an electric motor disposed in the head rail;
• a collar coupling operably engaged with the motor to engage the motor with the tube for rotating the tube;
• at least one dc battery, the at least one battery being the sole source of energy associated with the window covering, the at least one battery being disposable in the head rail;
• a control signal generator for generating a control signal;
• and
• an electronic circuit electrically connected to the control signal generator and the battery, the electronic circuit having an energized state for processing the control signal to cause the at least one battery to energize the motor to move the tube, the electronic circuit also having an idle state in which the at least one battery is not caused to energize the motor.

A powered shade assembly, comprising:

• a shade including a head rail, a rod rotatably disposed therein, and a window covering engaged with the rod for moving the window covering between a raised configuration and a lowered configuration when the rod is rotated;
• an electric motor disposed in the head rail;
• a coupling operably engaged with the motor to engage the motor with the rod for rotating the rod;
• at least one primary dc battery, the at least one battery being the sole source of energy associated with the window covering, the at least one battery being sufficiently small so as to be disposable in the head rail;
• a control signal generator for generating a control signal;
• and
• an electronic circuit electrically connected to the control signal generator and the battery, the electronic circuit having an energized state for processing the control signal to cause the at least one battery to energize the motor to move the rod.
