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 through operation of a lever coupling members of the articulated parallelogram. 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 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, a second end and a distal portion, the first end being rotatably coupled to the top member and the second end being rotatably coupled to the bottom member, the distal portion including a coupling point; and means pivotally connected to said coupling point for moving said constraint link to affect the shape of the parallelogram.
