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.
Claims24
A method for controlling a motorized roller shade, the method comprising:
- providing a roller shade that includes a shade attached to a shade tube;
- positioning a DC gear motor having an output shaft within the shade tube;
- operatively coupling the output shaft to a support bracket;
- detecting a manual displacement of the shade using a sensor;
- determining if the manual displacement is less than a maximum displacement;
- moving the shade to a different position by energizing the DC gear motor to rotate the shade tube if the manual displacement is less than a maximum displacement;
- maintaining a manually displaced position of the shade if the manual displacement is greater than a maximum displacement.
A motorized roller shade comprising:
- a shade tube;
- a shade attached to the shade tube;
- a DC gear motor positioned within the shade tube;
- the DC gear motor having an output shaft;
- the output shaft operatively connected to a support bracket;
- a motor controller operatively connected to the DC gear motor;
- an antenna operatively connected to the motor controller;
- a remote wirelessly connected to the antenna;
- and
- wherein the shade is movable to a different position by a tug on the shade, manual movement of the shade, or transmitting a wireless signal using the remote.
