Abstract (en)

[origin: US6050892A] An air outlet vent (1) adapted to be mounted in a floor (6) and connected to a heating, ventilating and air-conditioning air supply duct (30) includes a cylindrical housing (2) and a cover plate (4) that covers the top open end of the housing (2). The plate (4) includes a first group of air outlet openings in the form of concentric circular arcuate slits (11) extending over a first sector of the plate (4), and a second group of air outlet openings in the form of radially extending slits (12) in a second sector of the plate (4). The plate (4) is rotatably adjustable in the housing (2). With this arrangement, the direction of the main air flow axis of the air flow pattern generated by the vent can be infinitely rotationally adjusted around an imaginary inverted cone, to direct the air flow where desired and avoid undesirable drafts, while still providing a highly turbulent twisting or spiraling air flow characteristic.
