Abstract
An air vent comprising a first row of air vanes for controlling the lateral orientation of air emitted from the air vent and a second row of air vanes for controlling the vertical orientation of air emitted from the air vent. The first and second row of air vanes can be adjusted independently. The first row of air vanes has a control vane to which is mounted a control knob. The control knob is connected to the second row of air vanes by a ball joint mounted pin, whereby the vertical movement of the control knob results in rotation of the second row of air vanes about a horizontal axis. The control knob is connected to the first row of air vanes by links. The lateral movement of the control knob results in a corresponding parallel rotational movement of the first row of air vanes to control the lateral position of a concentrated stream of the air emitted from the air vent. The control knob is mounted for outward movement which results in rotation of the first row of vanes into a diffused position to diffuse the air emitted from the air vent. The sets of end vanes in the first row of vanes are rotated away from the control knob when the control knob is pulled outwardly of the housing…
