US Patent 9724590 Snow rider

The Snow Rider provides two separate platforms, each equipped with a pair of truck mounted skis, interconnected via a centerline articulated spar. Each platform undergoes an angle change before articulating with the trucks. This angle change is referred to herein as the truck angle, which determines the degree to which the skis turn relative to the long axis of the Snow Rider for a given amount of rotation of the platform about the centerline. The trucks translate leaning by the rider into a redirection of the skis, which through the use of ski riser mechanisms between the platforms and skis, are simultaneously rotated about their long axis to get the skis up on edge and in contact with the snow.
