Abstract
Abstract This invention relates to an elongated support unit for use in cooperating sets such as matched pairs. The unit has a frame having one or more substantially horizontal stages, one above the other, below its top. Each stage is equipped with a movable platform that can be drawn forward and retracted. The platform is disposed to share a load with at least one corresponding platform of another unit of the set. A set of the units can be adapted particularly well to carrying a CRT, computer, and/or printer across their tops and a keyboard borne on cooperating movable platforms therebelow.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
184 words
An elongated unit for stably sharing a load as one part of a cooperating set of companion units, said elongated unit comprising: a frame; and a movable platform, the frame including a substantially horizontal stage, a substantially horizontal load-supporting top thereabove, a track between said stage and said top, and an open front, said track, stage, and top being in a substantially parallel relationship, the movable platform being mounted on the track for sharing at least a fraction of the weight of a load with a corresponding movable platform of a companion unit, the movable platform being movable outwardly from a position under the top between said stage and said top and retractable back thereto, at least one side of the frame having an open area to allow a load that is partly borne by the movable platform to project beyond said at least one side and to move without impedance out of or into said open area in said at least one side as the platform is moved outwardly from a position under the top or is retracted back into a position thereunder.
