Snowmobile skis having elongated wing members

摘要

Snowmobile skis include at least one elongated wing member projecting laterally outward and upward from a lateral side of a base portion of the ski. The at least one elongated wing member has a lower surface that extends vertically over and laterally outward from a lower running surface of the ski. At least a longitudinal section of the lower surface of the at least one elongated wing member may include a portion having a curved, concave shape. The lower surface of the at least one elongated wing member may extend a greater distance vertically over the lower running surface of the ski near a longitudinal midportion of the ski relative to a distance by which the lower surface of the at least one elongated wing member extends vertically over the lower running surface of the ski near a longitudinal front portion of the ski and near a longitudinal rear portion of the ski.

主权项

1. A snowmobile ski comprising:
a base portion having a lower surface defining a lower running surface of the ski, the lower running surface of the ski extending in a longitudinal direction and a lateral direction, the longitudinal direction being defined from a tip of the snowmobile ski to a tail of the snowmobile ski, and the lateral direction being orthogonal to the longitudinal direction; and at least one elongated wing member projecting laterally outward and upward from a lateral side of the base portion, the at least one elongated wing member having a lower surface that extends vertically over and laterally outward from the lower running surface of the ski, the lower surface of the at least one elongated wing member extending a greater distance vertically over the lower running surface of the ski near a longitudinal midportion of the ski relative to a distance by which the lower surface of the at least one elongated wing member extends vertically over the lower running surface of the ski near a longitudinal front portion of the ski and near a longitudinal rear portion of the ski, such that a first longitudinal section of the lower surface of the at least one elongated wing member has a downwardly concave shape in the longitudinal direction near the longitudinal midportion of the ski, and a second longitudinal section of the lower surface of the at least one elongated wing member having a curved-over shape being curved and concave in the lateral direction.
