1. An ergonomically designed computer workstation comprising:

  • (a) a base means for location in a stationary position upon a supportive surface adjacent to a reference position which is the intended, or projected, work position of a computer operator,(b) a video monitor support means mounted upon such base,(c) said support means being adjustable within mechanically predetermined outer limits in any position in a vertically oriented plane passing through said reference position and the base of the support means,(d) said support means being adjustable along the plane in upwardly and downwardly and forwardly and backwardly directions in every position on the plane within the mechanically predetermined outer limits,(e) said support means being mechanically counterbalanced such that when adjusted for the weight of the support and a video monitor supported thereupon, said support means can be moved along the plane with only a minimum exertion of force and upon removal of said force will remain in the position in which it was at the cessation of the application of the force,(f) the mechanically predetermined outer limits of movement in the vertical plane being from a position within less than one dimension of the video monitor from the supportive surface to not less than substantially eye level of a projected operator in the reference position in a vertical direction and in a horizontal direction not less than from substantially directly over the base to within about a horizontal distance from the reference position which is the long leg of a right triangle the hypotenuse of which is the resting convergence distance of an average human eye with a line of vision extending at a downward angle of thirty-five degrees,(g) a keypad supported in a counterbalanced fashion upon two support arms at least indirectly mounted with respect to said base means such that said keypad is movable in a vertical plane passing through the reference position at least twelve inches in a vertical direction,(h) the keypad support arms being mechanically counterbalanced such that the keypad can be moved to a desired vertical position with only a minimum of exertion of force and upon removal of said force will remain in the position in which it was upon the cessation of the removal of the force,a locking means for rendering the keypad immovable during contact with the hands of an operator at the reference position during the keying in of data upon a keyboard supported by the keypad.
