FIELD: sports. ^ SUBSTANCE: riding board relates to the articles for sport and mass entertainment. It has pressure pads for feet, rollers intalled in the supports attached under the pressure pads and a mechanism connecting the pads. The mechanism connecting the pads is manufactured as two identical symmetric units attached to the pads from above and from below. Each unit of the mechanism is manufactured as two parts directed towards each other and each part has a flat-topped plate whose lateral surfaces are firmly tightened with the other flat-topped plate of the second part of the unit by means of a securing element and the plate crosspiece is equipped with a cylindrical lobe mounted on it and installed in the frictionless bearing installed on the pad surface of the connecting mechanism. One of the supports is manufactured as a pyramid whose base is located on the axis passing through the internal ring of the frictionless bearing secured on the board pressure pad by means of its race and the second support of the mechanism is manufactured as a V-shaped plate whose surfaces are secured with pipes entering the internal holes of their securing elements to reach the second pressure pad of the board. ^ EFFECT: enhanced structural reliability at fast riding on a bumpy road, reduced injury rate, improved learning capability for beginners. ^ 3 dwg |
