A sled having a frame with a seat portion, the frame being supported by two runners each located under one side of the frame, wherein each of the runners is movably connected to the frame by several levers. Each lever is mounted on the frame by a transverse pivot and each has a lower end connected to the runner, the levers allowing the runner connected thereto to move downwardly from a retracted position to an extended position at which latter position the side of the sled above that runner is lifted relative to a snow surface under the runner. A foot pedal may be provided on each side of the frame positioned for use by an occupant of the seat portion and connected to the levers so that pressure on a pedal on one side of the frame causes the levers on that side to extend the runner connected thereto, thus tilting the sled relative to the snow surface.

[ I claim:] [1.] A sled having a frame with a seat portion, said frame being supported by runners which include side runners, one of which is located under each side of the frame,wherein each of the side runners is movably connected to the frame by several levers, each lever being mounted on the frame by first transverse pivot means and each having a lower end connected to the runner by further transverse divot means, said levers allowing the runner connected thereto to move downwardly from a retracted position to an extended position at which latter position the side of the sled above that runner is lifted relative to a snow surface under the runner,wherein a foot pedal is provided on each side of the frame positioned for use by an occupant of the seat portion and connected to the levers of one runner so that pressure on one of said pedals on a side of the frame causes the levers on that side to extend the runner connected to that side,and wherein, on each side of the sled, the levers are in the form of bell-cranks each having a lower end pivot connected to the runner, an intermediate pivot mounted on said first transverse pivot means, and an upper end pivot connected by linkage to corresponding locations on the other levers, one of said levers being integral with said foot pedal.
