FIELD: sport.SUBSTANCE: ski pole comprises a rod, a supporting base of the pole, a hollow handle, a tubular hollow cylinder located in it, having the threaded holes, a damping means, the handle in the lower part is provided with means of retaining the tubular hollow cylinder. The ski pole comprises a handle formed with two closed cylindrical cavities, in the upper cavity of which a tubular hollow cylinder with openings is installed, an elastic cylindrical sleeve, a rod, means for filling the handle cavities with compressed air and the liquid, moreover, the pole is provided with means for controlling the magnitude of the length and rigidity of the pole, the rod is made of two parts interconnected by a lanyard, at that the rod with one end is located in the cylinder cavity, and the other end is connected with the upper half of the rod part.EFFECT: ski poles are designed with the ability to change different lengths depending on the height of the user and the mode of movement, to mitigate the shock loads from the hard interaction of the poles with the ground by damping or be rigid, to adjust the poles to the desired deformation, the track the height and rigidity of the pole through the adjusting means, to adjust the centre of gravity of the pole.3 cl, 4 dwg |
