Abstract

Apparatus and methods for controlling architectural opening coverings are described herein. An example apparatus includes a roller tube, a motor including a motor drive shaft and a motor casing, the motor casing to rotate with the roller tube, and a manual control including a manual control drive shaft coupled to the motor drive shaft, the motor to apply torque to the roller tube through rotation of the motor casing.

First claim

The invention claimed is:

1. An apparatus comprising:
a roller tube;
a motor including a motor drive shaft and a motor casing, the motor casing mounted to rotate with the roller tube, the motor casing and the motor drive shaft both contained within a periphery defined by an outside diameter of the roller tube;
a manual control including a manual control drive shaft rotatably fixed to the motor drive shaft, the manual control structured to apply torque to the motor drive shaft in response to a manually applied force to cause rotation of the motor casing and the roller tube without operating the motor, the motor structured to apply torque to the roller tube through rotation of the motor casing while the manual control drive shaft is rotatably fixed relative to the motor drive shaft; and a brake to keep the manual control substantially stationary while the motor is operated and the manual control is not operated.

2. An apparatus as defined in claim 1 , further including a gearbox having a gearbox drive shaft coupled to the motor drive shaft.

3. An apparatus as defined in claim 2 , wherein the motor casing is coupled to the roller tube via the gearbox.

4. An apparatus as defined in claim 2 , wherein the motor drive shaft is coupled to the manual control drive shaft by the gearbox drive shaft.

5. An apparatus as defined in claim 4 , further including a shaft connector coupling the gearbox drive shaft with the manual control drive shaft.

6. An apparatus as defined in claim 1 , further including a shaft connector structured to substantially prevent the motor and the manual control from applying torque to the roller tube in a first direction.

7. An apparatus as defined in claim 1 , further including a one-way roller bearing coupling the manual control to the motor drive shaft.

8. An apparatus comprising:
a manual control having a protrusion;
a female coupling configured to receive the protrusion;
a gearbox including a gearbox shaft coupled to the female coupling; and
a motor having a shaft rotatably fixed to the protrusion of the manual control via the gearbox, the manual control structured to transfer a manually applied force tot the shaft to rotate a casing of the motor without energizing the motor, the motor structured to rotate the shaft, the motor configured to be inserted into a roller tube of an architectural opening covering so that the casing of the motor and the shaft of the motor are contained within a periphery defined by an outside diameter of the roller tube; and a brake to keep the gearbox shaft substantially stationary while the manual control is operated and the motor is not operated.

9. An apparatus as defined in claim 8 , wherein the protrusion is a radial protrusion.

10. An apparatus as defined in claim 8 , wherein the gearbox is coupled to the female coupling by a clutch.

11. An apparatus as defined in claim 10 , wherein the clutch is a one-way clutch.

12. An apparatus as defined in claim 8 , wherein the manual control includes a brake.

13. An apparatus as defined in claim 12 , wherein the brake keeps the manual control substantially stationary while the motor is operating and the manual control is not operated.

14. An apparatus as defined in claim 1 , wherein the manual control drive shaft is partially contained within the roller tube.

15. An apparatus as defined in claim 8 , wherein the manual control is operatively coupled to the shaft to rotate the casing of the motor in response to the manually applied force without operating the motor.

16. An apparatus as defined in claim 8 , further including:
a roller tube rotatbly fixed to the casing of the motor to enable the motor to rotate the roller tube by applying torque to the shaft while the shaft is rotatably fixed to the manual control; and
a covering attached to the roller tube.
