Abstract
The present invention advantageously provides a motorized roller shade that includes a shade tube, a motor/controller unit and a power supply unit. The motor/controller unit is disposed within the shade tube, and includes a bearing, rotatably coupled to a support shaft, and a DC gear motor. The output shaft of the DC gear motor is coupled to the support shaft such that the output shaft and the support shaft do not rotate when the support shaft is attached to the mounting bracket.
Claims26
A motorized roller shade, comprising:
- a shade tube, including:
- an outer surface upon which a shade is attached, and
- an inner surface defining an inner cavity;
- a motor/controller unit, disposed within the shade tube inner cavity and mechanically coupled to the shade tube inner surface, including:
- a support shaft attachable to a mounting bracket;
- at least one bearing rotatably coupled to the support shaft,
- a DC gear motor having an output shaft coupled to the support shaft such that the output shaft and the support shaft do not rotate when the support shaft is attached to the mounting bracket, and
- a controller, coupled to the motor, to control the motor;
- and
- a power supply unit, electrically coupled to the motor/controller unit, disposed within the shade tube inner cavity and mechanically coupled to the shade tube inner surface, including a support shaft attachable to a mounting bracket, wherein the DC gear motor rotates with the shade tube when the DC gear motor is operating.
An internal motor/controller unit for a motorized roller shade, comprising:
- a support shaft attachable to a mounting bracket;
- an end cap, including at least one bearing rotatably coupled to the support shaft, attachable to an inner surface of a shade tube;
- a DC gear motor including an output shaft coupled to the support shaft such that the output shaft and the support shaft do not rotate when the support shaft is attached to the mounting bracket,
- a DC gear motor mount attachable to the inner surface of a shade tube;
- and
- a circuit board housing including at least one circuit board upon which a motor controller is mounted, wherein the DC gear motor rotates with the shade tube when the DC gear motor is operating.
An internal motor/controller unit for a motorized roller shade, comprising:
- a support shaft attachable to a mounting bracket;
- at least one bearing rotatably coupled to the support shaft;
- a DC gear motor, mechanically coupled to an inner surface of a shade tube, including an output shaft fixedly attached to the support shaft;
- and
- a controller, coupled to the motor, to control the motor,
- wherein the DC gear motor rotates with the shade tube when the DC gear motor is operating.
