Claims

[Scope of utility model registration request]

(1) In a ski that has a front half of the ski from the front ground contact line to the middle part, a back half of the ski from the middle part to the rear ground contact line, a sliding surface, and a weighted part, the left and right outer edges of the planar shape of the front half of the ski. A ski characterized in that each of the curves is formed in a convex curve with respect to the longitudinal centerline of the ski.

(2) The ski according to claim 1, wherein the convex curve is a circular arc curve.

(3) The ski according to claim 2 of the utility model registration claim, wherein the weighted portion of the side surface of the sliding surface is in contact with the horizontal surface in an unloaded state.

(4) The ski according to claim 3, wherein the side surface of the sliding surface is flat between the front ground contact line and the rear ground contact line.

(5) The ski according to claim 3, wherein the side surface of the sliding surface is convex between the front ground contact line and the rear ground contact line.

(6) The ski according to claim 4 or 5, wherein the left and right outer edges of the planar shape of the rear half of the ski are respectively convex curves with respect to the longitudinal center line of the ski.

(7) The ski according to claim 4 or 5, wherein the left and right outer edges of the planar shape of the rear half of the ski are respectively straight lines with respect to the longitudinal center line of the ski.

(8) The ski according to claim 4 or 5, wherein the left and right outer edges of the planar shape of the rear half of the ski are respectively concave curves with respect to the longitudinal center line of the ski.
