Abstract
Abstract A workstation for computer-aided design comprises an L-shaped main support frame having a monitor support panel which is both tiltable and slidable fore and aft. Connected between the horizontal elements of the L-shaped support frame is a secondary support frame carrying a digitizer support and a keyboard support. The keyboard support is forward and below the level of the digitizer support. The digitizer support is slidable fore and aft on the secondary frame, and the secondary frame itself is slidable fore and aft, and forwardly tiltable, relative to the main support frame. The main support frame rests on nylon feet, which are slidable on a table top. A centrally located foam pad is connected to the main support frame through a swivel mechanism, and is in compression and in frictional engagement with the table top, so that the workstation can be swivelled about a vertical axis, but translational movement is prevented.
