  • Patent number: 6767313
    Abstract: A parallel ski training or exercise apparatus is described. The ski training device provides the combination of parallel motion, edging, and weight shifting that characterizes downhill parallel skiing. Two foot platforms are mounted on a base, on independent rotation axes centered about the balls of the user's feet. The foot platforms are constrained to rotate together, i.e. their longitudinal axes remain parallel. The foot platforms can tilt from side to side to simulate the edging motion of downhill parallel skiing. Varying amounts of resistance to rotation and to tilting can be obtained by changing the springs or other devices that bias the foot platforms to straight-ahead and level alignment. The base of the parallel ski training device can be tilted to an angle by a support having a circular arc or hemispherical shape. With the front of the base raised, the user's ankles assume the leaning forward attitude that is used in parallel skiing.
