Abstract
Example architectural opening coverings powered by rotary motors are described. An example architectural opening covering apparatus includes a rotatable member, a covering mounted to the rotatable member, a motor having a drive shaft which is capable of rotating the rotatable member in a first direction to raise the covering and in a second direction opposite the first direction to lower the covering, and a drive shaft coupling substantially preventing the motor from applying torque in the second direction.
Claims28
A architectural opening covering apparatus comprising:
- a rotatable member;
- a covering mounted to the rotatable member;
- a motor having a drive shaft which is capable of rotating the rotatable member in a first direction to raise the covering and in a second direction opposite the first direction to lower the covering;
- and
- a drive shaft coupling substantially preventing the motor from applying torque in the second direction.

A architectural opening covering apparatus comprising:
- a rotatable member that is a driven shaft;
- a covering of pleated fabric mounted to the rotatable member and coupled to a lift cord;
- a motor having a drive shaft which is capable of rotating the rotatable member in a first direction to raise the covering by rotating a lift spool coupled to the lift cord and in a second direction opposite the first direction to lower the covering by rotating the lift spool;
- and
- a drive shaft coupling substantially preventing the motor from applying torque in the second direction.
A architectural opening covering apparatus comprising:
- a rotatable member;
- a covering mounted to the rotatable member;
- a motor having a drive shaft which is capable of rotating the rotatable member in a first direction to raise the covering and in a second direction opposite the first direction to lower the covering;
- and
- a one-way roller bearing to impede the motor from applying torque in the second direction.
