Abstract (en)
[origin: EP0473894A1] The invention relates to a threaded support (1) consisting of two tubes, in particular steel tubes, displaceable telescopically relative to one another and having a thread (7) which is formed on an inner tube (3) and on which an adjusting nut travels, the thread being rolled on. To obtain a design of improved usability for, as far as possible, the same strength of the inner and outer tube, the invention proposes that, on opening the thread flanks at an angle of about 80 DEG to 90 DEG , there is a thread depth t approximately equal to the remaining wall thickness a in the thread root. <IMAGE>
