Abstract (en)
[origin: US6250839B1] The present invention relates to a length-adjustable tube for ski poles or walking sticks, comprising on outer tube and a telescopically foldable inner tube which be inserted into the outer tube to adjust the length of the tube. Also included, is a expansion device with an expansion element which is held on the insert section of the inner tube and which can be pressed apart by exerting a quasi-radial pressure. The expansion device enables the inner tube to be axially and tightly clamped in the outer tube. In order to ensure that the expansion device engages inside the outer tube in all cases, it is provided that the expansion element pertaining to the expansion device if fitted on the area where it can be pressed apart by exerting a quasi-radial pressure with at least one soft-elastic friction element compensating diameter tolerance between the inner and outer tube and protruding above the outer periphery.
