Height-adjustable table with a linear or straight guide

Claim 1

A height-adjustable table comprising: a generally horizontal table surface; a linear guide located along a side of and below said table surface, including a stationary frame and a movable frame, for guiding vertical relative movement between said frames; a connection between one of said frame and table surface; each of said stationary frame and said movable frame being comprised of vertically extending closed hollow profiles, with one of said profiles being telescopically receivable within and completely enclosed by another of said profiles for guided relative movement of said frames; guide surfaces carried by each of said stationary and movable frames cooperable with one another during relative telescopic movement thereof to substantially preclude relative movement between said stationary and movable frames in longitudinal and transverse directions generally parallel to said table surface; each of said profiles having end edges, the end edges of said one profile being spaced inwardly from the end edges of said another profile to define between stationary and said moving frames a pair of generally vertically extending passageways extending substantially through the height of said guide.
