ABSTRACT:
A vertical Venetian blind employs a plurality of slats adapted to be moved between an open position and a closed position. When the slats are in their closed position, pivotally mounted spacer bars maintain a predetermined center-to-center distance between adjacent slats. A rotatable drive shaft, which is employed to move the slats between their open and closed positions, can be supported along substantially its entire length by a bearing to thereby prevent the drive shaft from sagging.
