An adjustable support allows a computer terminal or display device to be conveniently positioned above a desk. The support includes a platform for holding the terminal and a pivotally connected linkage assembly comprising proximal and distal arms for vertically and horizontally positioning the platform, the distal arm having the platform mounted thereon. The proximal arm comprises a set of members forming an articulated parallelogram structure, the proximal end of which is rotatable about a vertical post clamped to the desk. The vertical position of the terminal may be adjusted by changing the shape of the articulated parallelogram structure. As the shape of the parallelogram structure changes, the elevation of the distal end of the proximal arm changes which in turn affects the vertical position of the platform and display device.

An adjustable support comprising: a first pivot mechanism defining a first axis of rotation; a second pivot mechanism defining a second axis of rotation which lies in a plane parallel to a plane containing the first axis of rotation; and a polygonal structure connecting the first pivot mechanism to the second pivot mechanism, wherein said polygonal structure comprises: a top member; a bottom member a proximal member a distal member means coupling the top member, bottom member, proximal member, and distal member to form an articulated parallelogram structure; a constraint link having a first end and a second end, the first end coupled to the top member and the second end coupled to the bottom member; and torque means for applying torque to the constraint link about an axis which is perpendicular to the plane of the parallelogram.
