Abstract
Abstract A computer terminal support includes two vertical posts about which respective pivoting collars are free to pivot. Each pivoting collar is affixed to a swivel arm. A terminal support tray is affixed to an outer end of the outer one of the two swivel arms to thereby provide a substantial coverage area over which the computer terminal may be disposed. A vertical adjustment of the position of the outer pivoting collar on the outer vertical post is provided in order to permit adjustment of the vertical position of the display screen of the display device of the computer terminal. A horizontal pivot and a vertical pivot are provided for rotation of the computer terminal and its associated display screen of the display device in order to permit angular adjustment of the display screen anywhere within the coverage area for avoiding interference from glare.

Claim 1
Independent Claim
266 words
A computer terminal support for providing an adjustable and extensible mount for a computer terminal including at least a visual display screen, comprising: a king post; means for affixing said king post with a first axis thereof disposed in a substantially vertical position; first pivoting means rotatable in a substantially horizontal direction about said first axis; means for adjusting a vertical position of said first pivoting means along said first axis; a first swivel arm affixed to said pivoting means for concerted rotation therewith about said first axis; second pivoting means at a distal end of said first swivel arm rotatable in a substantially horizontal direction about a second substantially vertical axis; a second swivel arm affixed to said second pivoting means for concerted rotation therewith about said second axis; a third pivoting means at a distal end of said second swivel arm rotatable in a substantially horizontal direction about a third substantially vertical axis; a horizontally-disposed intermediate support tray affixed to said third pivoting means and movable therewith in a substantially horizontal direction about said third axis; a terminal support tray overlying said intermediate support tray and sized to support a computer terminal thereon; fourth pivoting means connecting said terminal support tray to said intermediate support tray for tilting movement about a fourth substantially horizontal axis whereby adjustment of a position of said computer terminal with five degrees of freedom is provided; and tilt-control means for manually moving and retaining said terminal support tray about said fourth axis to selected tilted positions, whereby said visual display screen is adjusted to the view of the user.
Claim 2
Dependent Claim
266 words
A computer terminal support for providing an adjustable and extensible mount for a computer terminal including at least a visual display screen, comprising: a king post; means for affixing said king post with a first axis thereof disposed in a substantially vertical position; first pivoting means rotatable in a substantially horizontal direction about said first axis; means for adjusting a vertical position of said first pivoting means along said first axis; a first swivel arm affixed to said pivoting means for concerted rotation therewith about said first axis; second pivoting means at a distal end of said first swivel arm rotatable in a substantially horizontal direction about a second substantially vertical axis; a second swivel arm affixed to said second pivoting means for concerted rotation therewith about said second axis; a third pivoting means at a distal end of said second swivel arm rotatable in a substantially horizontal direction about a third substantially vertical axis; a horizontally-disposed intermediate support tray affixed to said third pivoting means and movable therewith in a substantially horizontal direction about said third axis; a terminal support tray overlying said intermediate support tray and sized to support a computer terminal thereon; fourth pivoting means connecting said terminal support tray to said intermediate support tray for tilting movement about a fourth substantially horizontal axis whereby adjustment of a position of said computer terminal with five degrees of freedom is provided; and tilt-control means for manually moving and retaining said terminal support tray about said fourth axis to selected tilted positions, whereby said visual display screen is adjusted to the view of the user.
