ABSTRACT:
A snow toboggan, or a flat bottomed sled, has a body with a curved forward portion. At its aft end, the sled is outfitted with a pair of hinged drag panels, each hinged independently to the body of the sled. On the underside of each panel is disposed one or more spikes which are capable of digging into the snow. Also on the underside of the body near its aft end is fixed a longitudinally oriented fin which is used to stabilize the forward motion of the sled. On the underside of the curved portion of the body is pivotably supported a pair of front stabilizing fins which are used to stabilize the sled when the sled is travelling across a hill or traversing a hill, to prevent the forward end from sliding down the hill. When not needed, these front stabilizing fins are rotated up out of the snow so that sharp turns can be maneuvered. Sharp turns are obtained by lowering one panel at a time by suitable means mounted in the body to allow the spikes thereunder to grip into the snow. If both panels are lowered into the snow, the toboggan can stop or slow down. Suitable means are included to connect the panel to a respective foot-operated pedal disposed near the forward portion of the sled.
