FIELD: equipment for sportive and rehabilitation exercising by unskilled and professional skiers before starting skiing on the snow on classical skis, car wings, and also on water skis and snowboards. ^ SUBSTANCE: apparatus has upper and lower drive rolls, rotating rolls provided between upper and lower rolls, with resultant structure being arranged along arcuate b of inclined lateral frame bars. Fixed strip or hood serve for mounting of supporting sticks whose handles are positioned above movable slope simulating strip. Arcuate is defined by points of contact of internal side of endless slope simulating strip formed as endless mat with rigid springy bristles of 2-4 cm height with rotating rolls, lower drive roll and upper drive roll. Point A of contact between endless slope simulating strip and upper drive roll is at upper point of the latter. Distance d from straight line c, which connects point A of contact and point B of contact of endless slope simulating strip with lower drive roll along line f perpendicular to straight line c and extending through point D constituting outer point b of arcuate, is 2-5 cm. Part of supporting sticks below handles is formed as arcuate whose convex portion is directed toward contour of frame a. ^ EFFECT: wider range of sportive and rehabilitation skiing equipment. ^ 3 cl, 3 dwg |
