ABSTRACT:
A support carrier for the drive shaft of a vertical venetian blind is disclosed for supporting the drive shaft intermediate its ends, particularly when the blind is open. The support carrier moves along the drive shaft to a predetermined stop point so that a number of support carriers may be used if necessary positioned at various points along the drive shaft. The drive shaft moves the support carrier through a slip clutch engaged with the drive shaft, which clutch is a disk in slideable engagement with the facing inner surfaces of the casing walls of the support carrier.
