<p>The training aid for alpine skiing on snow-free slopes provides the possibility of practising alpine skiing, particularly slalom and giant slalom with a very similar technique to the skiing technique so that the training with this equipment does not represent any inconvenience to move from "preliminary" training to practising on natural snow. The aid is made from a profile (1) featuring two supports (3, 4) looking at opposite sides in front and in the back while on each leg (6, 7) of the supports (3, 4) there is at least one wheel (5) so that the axes (8) of the wheels (5) are at level and that the leg (6, 7) wheel (5) axes (8) of one support (3 or 4) are at an angle (alpha) open towards the centre of the profile (1) or the wheels (5) are on the same side of the profile (1) tangentially on the virtual arch (L). The legs (6, 7) of each support (3, 4) are connected to each other by a distancing mechanism (9) for adjusting the (alpha) angle.</p> |
