Abstract
In an alpine snow ski there is provided an asymmetric design in which the inside edge of the ski has a large sidecut with a short radius of curvature such that the centerline of a skier's foot when positioned in mounting plates on top of the ski is between about 5 and about 20 millimeters to the interior of the ski's inside edge and the mounting plates overhang the inside edge of the ski. The mounting plates are adjustable transversely to the inside edge of the ski and the outside edge of the ski is straight.
Claims16
In an alpine snow ski, comprising in combination:
- (a) a bottom inside edge, the edge having a sidecut;
- (b) a generally straight bottom outside edge;
- (c) a first side connected to the bottom inside edge;
- (d) a second side connected to the bottom outside edge;
- (e) a front end portion having a shovel connected to the first side and the second side, the shovel further having a tip;
- (f) a rear end portion having a tail connected to the first side and the second side, the tail further having a rear edge;
- (g) a central portion between the first side and the second side comprising the ski body having a top and a bottom extending a distance between the tip of the shovel and the rear edge of the tail, the distance defining the length of the ski;
- and
- (h) a radius of curvature defining the sidecut, the sidecut being an arc of a circle having a center, the center being the center of the curvature of the sidecut when the ski is placed on horizontal and vertical axes in Cartesian space with the tip of the shovel placed at the origin such that the radius of curvature is defined by the equation R=[(x-A).sup.2 +(y-B).sup.2 ].sup.1/2 and R is between about 10 feet and about 85 feet.
