<p>A mogul skiing simulating device having a floating platform (65) riding bearings on crank pins (92, 94) 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 (100) to its central support (78) 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 (204, 226) may be attached to the front and rear crank journals (116, 128, 163, 165) which act upon the ends of a leaf spring to store and release energy. The crankshafts are turned by and electrically powered 'V' drive (110).</p> |
