ABSTRACT:
Apparatus for selectively controlling the viewing angle of a video display unit by adjusting the tilt of the unit by means of a single, readily accessible manual control is disclosed. A viewer-operated control knob is used to rotate a shaft located within a linear recessed portion on an upper surface of a display support structure. The shaft includes right- and left-hand threaded portions to which lower end portions of respective support links are pivotally coupled allowing the linear displacement thereof. The upper end of each link is pivotally coupled to a support platform which is raised or lowered depending upon the direction of rotation of the control knob. A conventional video display unit is positioned upon the support structure which may take the form of an enclosed case for housing video display spare parts or additional circuitry. The support platform is positioned in contact with a lower, aft portion of the video display unit permitting its viewing angle to be easily adjusted by means of a single manual control. The tilt angle can be varied continuously between -5.degree. and +10.degree. with stable position locking available at any intermediate angle.
