Abstract
A vertically-adjustable leg assembly particularly suitable for a pedestal table, the assembly having telescoping inner and outer tubes of generally rectangular cross section with the external dimensions of the inner tube being sufficiently smaller than the corresponding internal dimensions of the outer tube to define a perimetric space between them. A pair of vertically-elongated, channel-shaped bearing blocks formed of rigid polymeric material are located in the space between the two tubes and are supported by the outer tube adjacent the open end thereof. At least one of the bearing blocks is adjustably mounted and is constructed so that adjustment forces exerted at spaced points will be distributed along the length of the block. The end of the inner tube disposed within the outer tube has channel-shaped bearing shoes, also formed of rigid polymeric material, secured thereto and slidably engagable with the inner surfaces of the outer tube.
