ABSTRACT:
A snow boarding training device includes a frame possessing a horizontal base and two spaced vertical posts. A tubular arcuate track extends between the posts and forms a segment of a circle lying in a plane inclined with respect to a horizontal plane at an angle between about ten and thirty degrees. An elongated support member formed in the shape of a snow board is secured adjacent a first, lower end to the base by a ball and socket mechanism. The support member is mounted for movement along the track by a guide roller assembly disposed on the bottom surface of the support member, adjacent a second opposite, upper end. The guide roller assembly includes two brackets mounting two pairs of rollers, with one roller of each pair positioned above the tubular track and having a concave surface conforming to the tubular track. Another roller of each pair is positioned below the tubular track and is adjustably mounted for pivotal movement, with the associated bracket, toward and away from the track, such that separation of the rollers can be adjusted to regulate resistance to movement of the support member along the track. Resilient disks are disposed at opposite ends of the track and form stops which limit the extent of movement of the support member along the track. As the support member moves upwardly from a lowest intermediate position on the track toward either side, a compound arcuate motion will be imparted to the support member, simulating a snow board.
