Abstract: A modular work station includes a dual column construction with a separately adjustable work surface supported on each column. Each of the columns utilizes a tubular telescoping construction and can provide as many as three individual modes of adjustable movement to the work surface, including lift, tilt, and horizontal back and forth movements. Supporting columns can be selected with varying functions to provide extremely broad versatility. The lift and tilt functions are preferably provided by motor driven linear actuators mounted within the telescoping column with appropriate controls to prevent contact between adjacent work surfaces when one or both of the surfaces is also provided with back and forth sliding movement.

Abstract: A raisable and lowerable table comprises a base, and at least one movably extensible vertical column attached to the base having a table top carried on the vertical column. Pivot means may be provided for moving the table top into any of a range of pivoted positions, preferably on both sides of the horizontal position of the table top. Motor are provided for holding the table top in any of the range of pivoted positions.
