Abstract
An improved snowmobile steering ski attachable to the steering spindles of a snowmobile and, generally, including a frame, which may be integrally molded as part of the ski, and having multiple protruding keels that emerge from the bottom running surface of the ski proximal the ski's front end and gradually increase in protrusion with respect to the bottom running surface to a point of maximum protrusion at a point on the ski runner near to the steering spindle of the snowmobile is disclosed. The keel then gradually decreases in protrusion from its maximum protrusion to merge back into the bottom surface proximal the rear end of the ski.
Claims6
A snowmobile steering ski assembly comprising:
- a frame for providing structural support to said ski and having attachment means for attachment of said frame to the steering mechanism of a snowmobile;
- and
- an elongated ski fixedly attached to said frame and having a curved bottom running surface having a first radius of curvature and structured for gliding over a surface of snow, an upturned front end having a relatively short radius of curvature, a rear end distal from said front end, and three curved protruding keels having a second effective radii of curvature smaller than said first radius of curvature of said bottom running surface, said protruding keels gradually emerging from said bottom running surface proximal said front end and extending along a portion of said length of said ski runner and gradually merging into said bottom running surface proximal said rear end and wherein said keels are molded as a part of said bottom running surface.
