Abstract:
A device adapted for enabling a rider, positioned on said device, to slide down a surface of a snow covered hill and control a direction of his slide by shifting his position on said device which constists of:a single board having a contoured bottom surface arranged for facing and contacting said surface of said snow covered slope and being symmetrical with respect to a center plane of said board; said board having a bulbous section that is concave looking down onto a top surface of said board and a flat section extending rearwardly from said bulbous section; two ridges formed on said bottom surface of said flat section; each one of said two ridges having one end proximal to an edge of said bulbous section and extending generally rearward away from said bulbous section along an edge of said flat section opposite said other ridge extending along an opposite edge of said flat section generally rearward away from said bulbous section along an opposite edge of said flat section; both of said two ridges having a curvature, said curvature being one of (i) concave toward said center plane; (ii) concave away from said center plane; whereby said device is adapted to provide that, when said rider on said top surface of said device is leaning forward to bring said bulbous section into contact with said surface of said snow covered hill, said board is free falling down said hill and when said rider is leaning back to where said ridges are in contact with said slope, then said rider is enabled to steer said board by leaning toward one ridge along one edge of said board to steer said board in one direction and leaning toward said other ridge on said opposite edge of said board to steer said board in an opposite direction.
