Height-adjustable table

Claim 1

In a table having a horizontally enlarged top having generally longitudinally extending front and rear edges joined by right and left end edges, and a leg structure fixed to an underside of said top and projecting downwardly therefrom, the improvement wherein said leg structure comprises: right and left upright leg arrangements disposed under said top respectively in the vicinity of the right and left end edges thereof; each said leg arrangement including a rigid lower leg unit having generally parallel and vertically extending front and rear elongate lower leg parts rigidly joined together in front-to-rear spaced relation by a cross structure; said leg arrangement including separate front and rear top leg members each having a vertically elongate tubular leg part which is respectively telescopically engaged over an upper portion of the respective lower leg part; height-adjusting connecting structure cooperating between each lower leg part and its respective telescopically engaged top leg part, said height adjusting structure including a plurality of vertically spaced openings extending transversely through one of the leg parts and alignable with an opening in the other leg part, and a locking pin being removably positioned within the aligned openings of the telescopically engaged legs parts; a horizontally elongated front support rod disposed closely adjacent the undersurface of said top in the vicinity of the front edge thereof and projecting longitudinally of the top and having opposite ends thereof joined to the front upper leg members; a horizontally elongated rear support rod disposed closely adjacent the undersurface of said top in the vicinity of the rear edge thereof and projecting longitudinally of the top and having opposite ends thereof joined to the rear upper leg members, said rear support rod extending generally parallel with but being laterally spaced rearwardly from said front support rod; bracket means mounted on the undersurface of said top for supporting said front and rear support rods, said support rods and the connection thereof between said brackets and the respective top leg parts permitting limited rotational movement of the top leg parts relative to the top substantially about the longitudinal axis of the respective support rod; whereby the telescopically engaged rear leg parts can be adjusted to a slightly different height than the telescopically engaged front leg parts so as to position the top at a slight incline in a widthwise direction.
