<p>The height adjustable standing foot has a pillar (30) consisting of telescopically assembled outer (3) and inner (4) sections which can be relatively fixed in different positions. The inner contour of the outer section in cross section conforms section-wise to the outer contours of inner profiles differing in their cross sectional form in such a way that the different inner profiles are supported flat over the length on at least three relatively offset inner contour sections by at least three outer contour sections spaced apart in the circumferential direction, thereby preventing tilting in the transverse direction.</p> |
