The utility model relates to sports equipment and can be used as a personal sporting and transportation means for transporting a person, which is driven by human muscle power, and can be used in tourism, leisure and sporting events on roads with hard surfaces. The technical result is an increase in the service life of roller skates, a decrease in the weight thereof, and an increase in skating speed and manoeuvrability. Each skate comprises a support platform for the user's foot and, mounted below the platform, at least two balls, each of which is pivotally mounted in a fastening member that is fastened to the support platform, and lateral support castors, disposed on either side of each ball. The fastening member is configured in the form of a hemisphere which encloses the top portion of the ball and consists of at least three arcs connected by a lower rim which is situated below the horizontal plane of symmetry of the ball. In the top portion of the ball there are secured at least three rotating bodies which contact with the ball, and in the lower rim of the hemisphere there are disposed equidistantly at least three rotating bodies which likewise contact with the ball. The lateral castors are disposed on height-adjustable brackets. |
