Abstract
A snow ski has at least one channel formed in the running surface to expose the inner sides of the ski edges for translating the force exerted by the ski during a turn and creating positive engagement with the skiing surface. The channel may extend the length of the ski or only a portion thereof. The channel forms edge tips on the ski edges where the inner sides are exposed. The edge tips may have different shapes to improve the bite on the skiing surface.
Claims20
A ski exhibiting improved control in icy and hard packed snow skiing conditions, comprising:
- a ski body having a tip, a tail, ski sides, and a boot binding region, a lower surface of the ski body forming a planar running surface for contacting a skiing surface;
- ski edges extending along each ski side of the ski body adjacent the running surface between the tip and tail, one surface of each ski edge being an outer side that is exposed along the ski side, and a second surface that lies substantially in the plane defined by the planar running surface, for contact with the skiing surface when the running surface is flat on the skiing surface;
- at least one recessed area forming at least one channel in the running surface, the channel extending alongside and parallel to at least one of the ski edges of the ski for at least part of the length of the ski body to expose an inner side surface of the ski edge.
A ski having improved turning and control in icy or hardpack snow conditions, the ski comprising:
- a ski body having a tip, a tail, ski sides, and a boot binding region, a lower surface of the ski body forming a planar running surface for contacting a skiing surface;
- ski edges extending along each ski side of the ski body adjacent the running surface between the tip and tail, one surface of each ski edge being an outer side, at least a portion of an inner side of one of the ski edges being exposed to the skiing surface, the exposed inner side and corresponding outer side forming an edge tip that lies substantially in the plane defined by the planar running surface, for contact with the skiing surface when the running surface is flat on the skiing surface.
