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.

First claim

What is claimed is:

1. A motorized window shade system comprising:
shade material;
the shade material extending a length from an upper end to a lower end;
a DC electric motor;
the shade material operatively connected to the motor such that operation of the motor changes the position of the shade material;
a gear reducing assembly operatively connected to the motor;
a motor controller operatively connected to the motor;
the motor controller configured to control operation of the motor;
an antenna operatively connected to the motor controller;
a power supply electrically connected to the motor;
wherein the power supply includes at least one battery;
a housing;
wherein the motor, the gear reducing assembly and the power supply are positioned within the housing;
a remote control device wirelessly connected to the antenna;
wherein the shade material is movable to a different position by transmitting a wireless signal to the motorized window shade system using the remote control device;
a counterbalance assembly;
the counterbalance assembly operatively connected to the motorized window shade system;
wherein the counterbalance assembly is configured to provide a counterbalance force.

2. The motorized window shade system of claim 1 wherein the housing is formed in a generally cylindrical or tubular shape.

3. At motorized window shade system comprising:
shade material;
the shade material extending a length from an upper end to a lower end;
a DC electric motor;
the shade material operatively connected to the motor such that operation of the motor changes the position of the shade material;
a gear reducing assembly operatively connected to the motor;
a motor controller operatively connected to the motor;
the motor controller configured to control operation of the motor;
an antenna operatively connected to the motor controller;
a power supply electrically connected to the motor;
wherein the power supply includes at least one battery;
a housing;
wherein the motor, the gear reducing assembly and the power supply are positioned within the housing,
a remote control device wirelessly connected to the antenna;
wherein the shade material is movable to a different position by transmitting a wireless signal to the motorized window shade system using the remote control device;
wherein the shade material is further movable to a different position by a tug, which is a manual displacement less than a predetermined maximum displacement.

4. A motorized window shade system comprising:
shade material;
the shade material extending a length from an upper end to a lower end;
a DC electric motor;
the shade material operatively connected to the motor such that operation of the motor changes the position of the shade material;
a gear reducing assembly operatively connected to the motor;
a motor controller operatively connected to the motor;
the motor controller configured to control operation of the motor;
an antenna operatively connected to the motor controller;
a power supply electrically connected to the motor;
wherein the power supply includes at least one battery;
a housing;
wherein the motor, the gear reducing assembly and the power supply are positioned within the housing;
a remote control device wirelessly connected to the antenna;
wherein the shade material is movable to a different position by transmitting a wireless signal to the motorized window shade system using the remote control device;
wherein the shade material is further movable to a different position by a manual movement, wherein a manual movement is a manual displacement greater than a predetermined maximum displacement.

5. A motorized window shade system comprising:
shade material;
the shade material extending a length from an upper end to a lower end;
a DC electric motor;
the shade material operatively connected to the motor such that operation of the motor changes the position of the shade material;

a motor controller operatively connected to the motor;
the motor controller configured to control operation of the motor;
an antenna operatively connected to the motor controller;
a power supply electrically connected to the motor;
wherein the power supply includes at least one battery;
a housing;
wherein the motor, the gear reducing assembly and the power supply are positioned within the housing;
a remote control device wirelessly connected to the antenna;
wherein the shade material is movable to a different position by transmitting a wireless signal to the motorized window shade system using the remote control device;
wherein manual movement is detected by a sensor system.

6. A motorized window shade system comprising:
shade material;
the shade material extending a length from an upper end to a lower end;
a DC electric motor;
the shade material operatively connected to the motor such that operation of the motor changes the position of the shade material;
