Column length-adjustable as well as axial bearing, and assembly procedure for an adjustable-length column of this kind.

摘要

Column adjustable length and axial bearing, and assembly procedure for a column of adjustable length of this class.; The column is designed for chairs or the like and comprises a vertical tube with a longitudinal axis (A) and a piston and cylinder unit. A longitudinal end of this unit is locked in the axial direction by means of an axial bearing (22) in a base plate (12a) of the standpipe. For this, the axial bearing (22) is fixedly connected to the longitudinal end of the cylinder and piston in the axial direction (A). Furthermore, the axial bearing (22) has at least two locking arms (42), by which it can be locked in the base plate (12a) of the standpipe and a fastening bolt (44), the binding performed on the shaft between the axial bearing (22) and the bottom (12a) of the standpipe can be introduced by the cylinder and piston between the locking arms (42) and thus ensures the locking.
