Abstract
A retractable motor-driven awning can be extended or retracted by energizing the motor in one direction or another. A manually operable system, however, is also employed for rotating the awning by hand in a direction to retract the awning in the event the motor drive becomes inoperable. The ability to hand rotate the roll bar to retract the awning is achieved by connecting the roll bar to the drive shaft of the motor with a manual override system. Implementations of a manual override mechanism include one-way bearings and various ratchet designs.
