| 摘要 |
The invention relates to a telescopic column (1) having an outer tube (2) and at least one first inner tube (3), wherein the at least one first inner tube (3) is equipped with a plain bearing (5), which has a first sliding set (6), which comprises a plurality of sliding elements (61, 62,..., 6n), which are arranged between the first inner tube (3) and the outer tube (2) in the circumferential direction on the outer wall (8) of the first inner tube (3), by means of which sliding elements the two tubes (2, 3) are guided in such a way that the two tubes can be slid longitudinally in relation to each other. At least some or all of the sliding elements (61, 62,..., 6n) are custom-made and have a contact and/or sliding surface (9) that is a) worked, milled, and/or ground down to a specified material thickness or b) built up and/or printed to the specified material thickness by means of a 3-D printer, wherein the specified material thickness is selected in such a way that the play of the first inner tube (3) in relation to the outer tube (2) lies below a threshold value, or preferably there is no play of the first inner tube in relation to the outer tube. |
