  • Patent number: 4456285
    Abstract: 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.

  • Patent number: 4448442
    Abstract: An improved ski pole having an adjustable length is provided with two telescopically movable tube sections. The tube sections are inserted into each other and are movable relative to each other and are provided with a latch and a plurality of catches. When shortening the length of the ski pole, a spring is tensioned. The increasing of the length of the ski pole is caused by the tensioned spring. The switch is arranged at the reverse side of the grip of the ski pole. The latch is arranged fixedly at the inner tube section and the catches are arranged at a pivotable cylinder which can be elevated and lowered as well as rotated. The catches are defined by horizontally extending sections of at least one Z-shaped groove. The pivoting cylinder is connected at a off-center pivot point to the switching or operating, respectively, member. The entire mechanism for the longitudinal adjustment of the ski pole is arranged in the gripping section of the ski pole.
