MOTOR DRIVE SYSTEM FOR WINDOW COVERING SYSTEM WITH CONTINUOUS CORD LOOP

摘要

A motor-operated drive system for a window covering system including a headrail, a mechanism associated with the headrail to spread and retract the window covering, and a continuous cord loop extending below the headrail for actuating the mechanism to spread and retract the window covering. The drive system includes a motor, a driven wheel that engages and advances the continuous cord loop, and a coupling mechanism for coupling the driven wheel to a rotating output shaft of the motor for rotation of the driven wheel. The drive system includes a channel system for redirecting the continuous cord loop engaged by the driven wheel, or other mechanism for configuring the drive system so that continuous cord loop extends in a substantially vertical orientation. The coupling mechanism includes an engaged configuration in which rotation of the output shaft of the motor causes rotation of the driven wheel, and a disengaged configuration.

1. A drive system, for use in combination with a window covering system including a headrail, a mechanism associated with the headrail for spreading and retracting a window covering, and a continuous cord loop extending below the headrail for actuating the mechanism associated with the headrail for spreading and retracting the window covering, the drive system comprising:
a motor configured to rotate an output shaft of the motor; a driven wheel; a coupling mechanism coupling the driven wheel to the output shaft of the motor configured to rotate the driven wheel in the drive system, the continuous cord loop being engaged by the driven wheel to advance the continuous cord loop during rotation of the driven wheel; and a housing for the drive system including at least one opening, the continuous cord loop being routed from the driven wheel to the at least one opening in the housing, and the continuous cord loop extending below the headrail of the window covering system to the at least one opening in the housing; wherein the coupling mechanism includes an engaged configuration in which rotation of the output shaft of the motor causes rotation of the driven wheel, and a disengaged configuration in which the driven wheel is not rotated by the output shaft of the motor.
