Adjustable dual worksurface support

A dual worksurface support for electronic data processing equipment and the like, comprising:

• a first worksurface adapted to support a first piece of equipment thereon;
• a second worksurface positioned adjacent said first worksurface, and adapted to support a second piece of equipment thereon;
• a linkage assembly interconnecting said first and second worksurfaces in a manner which permits said second worksurface to be adjusted vertically with respect to said first worksurface, and including:
• a first linkage having one portion thereof connected with one side of said second worksurface, and an opposite portion thereof pivotally connected with a corresponding one side of said first worksurface at a first pivot point for rotation about a preselected horizontal pivot axis;
• a second linkage having one portion thereof connected with an opposite side of said second worksurface, and an opposite portion thereof pivotally connected with a corresponding opposite side of said first worksurface at a second pivot point disposed laterally aligned with said first pivot point for rotation about said horizontal pivot axis;
• a substantially rigid, elongate stabilizer bar having one end thereof rigidly connected with said first linkage generally adjacent said first pivot point, and an opposite end thereof rigidly connected with said second linkage generally adjacent said second pivot point, whereby rotation of one of said first and second linkages is transmitted through said stabilizer bar to the other of said first and second linkages to insure that the opposite sides of said second worksurface move vertically together without sagging or binding;
• and wherein
• said first linkage includes first and second rigid arms arranged in a side-by-side relationship, and having opposite ends thereof pivotally connected with said first and second worksurfaces in an arrangement which defines a first parallelogram linkage;
• and
• said second linkage includes first and second rigid arms arranged in a side-by-side relationship, and having opposite ends thereof pivotally connected with said first and second worksurfaces in an arrangement which defines a second parallelogram linkage.
