Abstract
An air duct outlet that allows a user to redirect an air stream within a wide range of directions includes a housing having a planar first wall and a convexly-curved second wall in adjacent, spaced-apart relationship and that define an air passageway having an inlet and a flared outlet. A vane is pivotally attached within the air passageway and is movable within a range of positions that are increasingly transverse to the first wall. An air stream flowing through the air passageway is deflected by an amount that increases with each position of the vane in the range such that the air stream adheres to a portion of the second wall by an amount that increases with each position of the vane in the range and such that the air stream exits from the outlet in a direction that is increasingly transverse to a direction normal to the outlet.
