Abstract
A snow skate is disclosed which provides improved control and skate-like performance, particularly on hard-pack or icy surfaces. The snow skate has edges which increasingly project from the central flat region of the ski to the forward area. Preferably this is achieved by making the base increasingly concave forward and rearward from a central generally flat region.
Claims22
A snow skate, comprising an elongated ski body having an upturned front end and a rear end, said ski body comprising:
- a) an upper surface adapted to receive a boot binding for releasably securing a boot to said upper surface intermediate said front and rear ends;
- b) a base surface having a central generally flat zone and a first zone of increased edge projection forward of said flat zone;
- and
- c) longitudinal edges extending along opposed sides of said base surface;
- wherein the depth of said edges below said base increases continuously from said flat zone towards said zone of increased edge projection forward of said flat zone wherein said base surface further comprises a second zone of increased edge projection rearward of said flat zone and the depth of said edges below said base increases continuously from said flat zone towards said second zone of increased edge projection.

- and
- c) longitudinal edges extending along opposed sides of said base surface;
- wherein the depth of said edges below said base increases continuously in a forward direction in said zone of increasing edge projection forward of said flat zone and wherein a tangential angle is formed at a selected distance forward of said flat zone by said base surface with a transverse horizontal line extending between corresponding lowermost points on said opposed longitudinal edges at said selected distance forward of said flat zone and wherein said tangential angle formed by said base surface with said horizontal line in a region adjacent said longitudinal edges increases within said zone of increasing edge projection forward of said flat zone to greater than 45 degrees.

- a) an upper surface adapted to receive a boot binding for releasably securing a boot to said upper surface intermediate said front and rear ends;
- b) a base surface having a central generally flat zone and a transversely concave zone of increasing edge projection forward of said flat zone thereby forming a transverse concavity in said base surface forward of said flat zone;
- and
- c) longitudinal edges extending along opposed sides of said base surface;
- wherein the transverse concavity of said base surface forward of said flat zone increases continuously in a forward direction in said zone of increasing edge projection forward of said flat zone and wherein a tangential angle is formed at a selected distance forward of said flat zone by said base surface with a transverse horizontal line extending between corresponding lowermost points on said opposed longitudinal edges at said selected distance forward of said flat zone and wherein said tangential angle formed by said base surface with said horizontal line in a region adjacent said longitudinal edges increases within said zone of increasing edge projection forward of said flat zone to greater than 45 degrees.
