ABSTRACT:
A louver assembly particularly useful for air-conditioning units and other like appliances comprises a frame defining an opening; a first group of slats extending along one coordinate axis mounted to the frame within the opening and pivotable about that axis; a second group of slats extending along a second coordinate axis mounted on the first group of slats within the opening and pivotable about that axis; and a manipulatable knob coupled to both groups of slats such that moving the knob in a direction parallel to the second coordinate axis pivots the first group of slats about the first coordinate axis, and rotating the knob about the second coordinate axis pivots the second group of slats about the second coordinate axis.
