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.

A vertical Venetian blind, comprising a plurality of blocking means for blocking solar rays; supporting means for supporting each of said blocking means in a generally vertical orientation; moving means for moving said blocking means along said supporting means between a closed position and an open position; rotating means for rotating each of said blocking means about a generally vertical axis of rotation associated therewith; and coupling means for coupling and uncoupling adjacent pairs of said blocking means in response to the movement of said blocking means along said supporting means, said coupling means including a plurality of spacer bars, each spacer bar being pivotally attached to one blocking means of a corresponding one of said adjacent pairs of said blocking means and being pivotal between a first position in which it is disengaged from the other blocking means of said corresponding one of said adjacent pairs of blocking means and a second position in which it is engaged with said other blocking means to thereby maintain a predetermined spacing between said one blocking means and said other blocking means, all of said spacer bars being in their second position when said blocking means are in their closed position, whereby said blocking means are spaced apart at predetermined intervals along said supporting means when they are in their closed position.
