WINDOW COVERING WITH IMPROVED CONTROLS |
摘要 |
A control mechanism provides a clutch module for selective locking and unlocking of a drive shaft used to retract and extend the shade element between storage and extended positions. The clutch module includes a reciprocator element that engages a key extending from an outer surrounding housing. A locking member between the reciprocator element and a coupling element carried by the drive shaft selectively locks and unlocks rotational coupling between the reciprocator element and the coupling element, thus selectively locking and unlocking the drive shaft. A cushioning mechanism, a unidirectional dampening or frictional deceleration is provided for the drive shaft. The cushioning mechanism includes an impeller or rotor immersed in a cushion medium that impedes rotation of the rotor, and hence the drive shaft to which the rotor is coupled. |
