FIELD: sports.SUBSTANCE: ski-steppers relate to articles of sports inventory and are designed for skiing amateurs and for sportsmen in their training process. From all sports skis are most valuable for humans. Since people began walking on feet such method of movement was needed, which would allow to use hands, while walking. Such method found its embodiment in ski walking. Need of snow cover for walking on skis was eliminated with help of wheel skis. Device, disclosed here, can help to get rid of bad roads. Essence of this proposal consists in fact, that device is equipped with artificial ski track in form of sections of ski guides, limiting movement of ski length, width and height of guides, each of which is attached through spring to ski, shortened to sizes of ski binding, so, that during movement of ski along it under effect of muscular energy of skier spring mechanism is brought, which at moment of transfer of center of gravity of skier on the other leg releases this energy and actuates ski guide extending it in front of ski to make next step of ski movement forward. Ski is equipped with ratchet mechanism and sliding elements like sledges or rolling elements like carriage for movement inside ski guide cavity. Ski guides installed as platforms of known leg wheeled means (ski rollers), in good roads give effect of summation of speed from one leg or hand push of skier.EFFECT: ski-steppers are presented.1 cl, 5 dwg |
