FIELD: sport.
SUBSTANCE: invention relates to sport and particularly to devices intended for rolling on alpine skiing when snow is absent. Invention is intended for increasing the period of ski centres use for skiing in snow-free seasons and ensures rigidity of transport strip edges. Imitator includes two roller boards for right and left leg with fastening elements for boots. Three roller units are installed on each board. Each unit consists of two cylinders freely rotating on bearings enclosed into transport strip. Sprockets are installed at cylinder ends. They are interconnected by means of chain and spring-mounted turnbuckles. Length of central cylinders and width of transport strip is less than those installed on board ends. Roller units are enclosed into frames, which are rigidly connected to bottom surface of board. Axis of cylinder rotation is perpendicular to board symmetry axis.
EFFECT: increase of alpine skiing centre period of use for skiing in snow-free seasons.
