FIELD: sports.SUBSTANCE: invention relates to skiing and skating. The roller skis are made shortest possible, without losing contact with the track during the race and therefore they do not depend on the height of the user, they are easy to operate, easy to carry, transport, store. The roller skis comprise a base made in the form of a longitudinally closed box structure of lightweight durable wear-resistant material, with the ability of placing in the box cavity of elastic chambers filled with gas, with the ability of elastic deformation from dynamic loads during the leg push by changing the stiffness of the base due to the gas pressure control in them. On the base the replacement trolleys are mounted with the ability of their rearrangement and fixing along the length of the roller skis, on one of which the wheels, the mechanism for preventing backward motion, the mechanism of its switching off, and the control mechanism of interaction of wheels with the mechanism of backward motion are mounted.EFFECT: increased efficiency of the roller skis through the use of control mechanisms.10 cl, 18 dwg |
