Abstract
Single-row roller skates with widened parameters of movement for figure skating on dry surfaces as on ice, said skate comprising a rigid foot plate mounted on spatial cylindrical body of circular cross section, said body has supports for rotating bearings in horizontal axis of motion and has bung (stop) housings extended on both ends for mounted bearing elements and on them supports for twin-carrier yokes having near the supports of said bearing elements spring elements of regulated brakes remaining in elastic contact with rotating brake surfaces of bungs also having on their opposite ends on shoulders formed spatial yokes, said yokes in horizontal static position form supports for vertical auxiliary eliptical surface rollers, said bi-plane yokes interconnected for mounting front and rear main bearings of skate rollers, said rollers have generating surfaces of coaxial microgrooves, said grooves parallel to plane of roller rotation in direction of travel; said skate has distinctive length between axes of front and rear rollers, said length depends on length of skater's foot and is adjustable by mechanism for change of skate length and blocking by frictional resistance.
