Abstract: A mogul skiing simulating device having a floating platform riding bearings on crank pins of two crankshaft assemblies while accommodating the changing distance between the two crankshaft pins during their rotation. The leader crankshaft assembly is about 30 to 35 degrees ahead of the follower. The platform is tethered by springs to its central support to maintain the platform in the correct relation to both pairs of crankshaft assemblies. The springs pull from a plastic bushings on each crankshaft pin toward the center of the platform. The tilt of the entire machine is higher in the rear to simulate downhill skiing. Cams may be attached to the front and rear crank journals which act upon the ends of a leaf spring to store and release energy. The crankshafts are turned by and electrically powered “V” drive. Railing allows the user to vary hand placement and body position.

Abstract: An exercise apparatus especially suitable for simulating mogul skiing conditions. The apparatus may comprise a base which supports a rotatable component which, in turn, supports a platform for supporting a user. The rotational component includes a unidirectional element limiting the direction of rotation of the rotational component to a single direction. A biasing assembly assists and resists the movement of the rotational component and varies the speed of the rotational component in response to a displacement of the rotational component. An alternative exercise apparatus includes a pair of spaced rotational components driven by a prime mover via a power transmitting element. A platform is operatively connected to the pair of rotational components via a platform support assembly. One rotational element leads the other rotational element so as to vary the angular disposition of the platform throughout the rotation of the rotational elements. The prime mover is preferably a variable speed motor.
