DEVICE FOR MOVEMENT ALONG ICE AND SNOW SURFACE Russian patent published in 2018 - IPC A63C1/00 

FIELD: sport.

SUBSTANCE: invention relates to road engineering for various purposes, and specifically to ski, sleigh, bobsleigh, ski-skating, skating, bicycle sports and walking activities. On the axis inside device front fork for movement along icy and snowy surfaces a skid is hingedly mounted, and rear end wheel (propulsor) is elliptical in shape with a protector fixed, which has large coefficient of sliding friction when interacting with roadway when ellipse major axis coincides with Y axis of Cartesian system, when wheel is turned clockwise, forward motion is carried out using wheel and at least three skid, two behind and one in front, and inertial slip on skid, when ellipse small axis coincides with Y-axis, whereas device for moving along the ice and snow surfaces contains device, designed to lock the wheel when ellipse small axis coincides with Y axis.

EFFECT: provides inertial slip on skid throughout desired part of roadway.
