  • Air-direction adjusting apparatus for air-conditioning equipment
    Patent number: 5839953
    Abstract: A mechanism for controlling the flow of air from an air-conditioning unit includes a row of guide vanes which are pivotally held by an outlet nozzle. The guide vanes are located at the lower end of an air course which has been formed within a body of the air-conditioning unit. The guide vanes control the flow of air in both left and right directions. This new design is characterized in that the angle of inclination of each guide vane progressively changes toward the end of the row. The air flow is controlled accurately in both the left and right directions so that the air flow reaches the desired location.

  • Air-direction adjusting apparatus for air-conditioning equipment
    Patent number: 5833532
    Abstract: In an apparatus in which a blow-out nozzle is provided at a lower end of an air course formed in the inside of a body of the air-conditioning equipment and blown air passed through the air course is blown out of a blow-outlet while guided in the left/right direction by a plurality of parallel guide vanes pivotally held by the blow-out nozzle, wherein each vane has a C-shaped annular pivotal bearing and a sleeve fitted into the bearing, a shaft extending from an inner wall of the nozzle being inserted into the sleeve, the shaft having claws which project from the upper end portion of the shaft so as to retain the sleeve.
