ABSTRACT:
A louvered blind structure comprising a support frame, one side of which is straight and the other side not parallel to the straight side. A plurality of elongated slats are pivotally connected to the straight side at one end, and at their other end to blocks which are in turn pivotally mounted in the non-parallel side about an axis which is transverse to the longitudinal axes of the slats. An actuator structure is mounted in the straight side for simultaneously pivoting the slats between open and closed position. The louvered blind structure is adapted to be mounted within the air space of a double-glazed sealed window unit.
