A longitudinally adjustable ski pole is provided with two tube sections arranged telescopically movable into each other and are provided with a latch and several catches. When shortening the ski pole a spring is tensioned. An extending of the ski pole in longitudinal direction is caused by the tensioned spring. The switching element is arranged, for instance, at the rear side of the hand grip of the ski pole. The latch is supported at the outer of the tubes and the catches are located at the inner of the two tubes. The catches are formed as a through hole through the tube and comprise a supporting shoulder provided with a supporting face. The latch is arranged at a tilting lever which is spring biased and operationally connected to a switching member. The entire mechanism for the longitudinal adjustment of the ski pole is arranged in the grip section of the ski pole. This grip section can quite easily be mounted to the common ski pole tubes. The ski pole is intended specifically for cross-country skiers who can adjust the pole during the skiing proper to three various lengths whereby a chosen length is arrested by a form closed locking of the two tubes telescopically inserted into each other. The latch may be brought by means of the switching member into an intermediate position, in which it does not engage into any one of the catches such that no locking of the two tubes is present such that an elastically yielding ski pole is provided. |
