Patent ID: 8876144

Claim:
A snow mobility device that defines a longitudinal axis, the snow mobility device comprising: a generally planar deck with a top surface and a bottom surface, the deck defining a front portion, a rear portion, a middle portion and outer edges, wherein the middle portion is generally flat except for a raised platform in its middle, and the front and rear portions are each curved upwardly, and wherein the edges are rounded; two rails extending outwardly from the bottom surface along all of the middle portion and at least some of each of the front and rear portions, the rails spaced from one another and essentially parallel to the longitudinal axis of the snow mobility device, wherein the rails are generally triangular shaped in cross section, with the base on the bottom of the deck and the vertex located farthest from the bottom, wherein the rails are essentially equally spaced from the longitudinal edges of the deck and wherein the rails are generally parallel along their lengths except for along the front portion where they diverge outwardly from each other, to define a funnel that guides snow into the space between the rails, and wherein the rails extend close to or all the way to the edges of the front portion; and a pair of retractable cleats coupled to the deck, wherein the cleats are generally “V”-shaped, wherein each cleat is part of a cleat assembly that comprises a lever that couples with the cleat, and a housing that holds the lever such that it can be operated by a user to extend and retract the cleat relative to the deck, wherein each cleat assembly comprises a cleat, a lever, a housing base and a housing cover, wherein the base is attached to the deck and the lever comprises a structure located inside of the cover and that fits into an opening in the cleat.
