ABSTRACT:
Floor vents for alternately supplying air to a conditioned space. Such vents, used in combination with a heating or cooling system, facilitate the delivery of air in a desired direction. The plastic vent may be constructed of pigmented material in a desired color. Louvers with integrally formed gears are pivotally mounted between ends of the vent, and are repositioned by a thumbwheel located below the upper surface of the grille portion of the vent, to thereby avoid damage to the gear by foot traffic above the vent. The louvers are provided with integrally formed bushings and rotatable end elements to enhance rotation and reliability.
