| 20100127467 | Snowmobile ski runner and method of manufacture - Traction enhancing runner assemblies for mounting underneath a snowmobile ski. The runner assemblies of this invention are a single rail with double edges to provide parallel runner bars, but the runner bars are not adjacent each other such that they provide a “staggered” runner arrangement which enhances the traction of the runner bar and hence the stability of the snowmobile on which they are mounted. Also, the double edges are provided with novel grooves that contain hard welds or carbide inserts to enhance the wear characteristics of the runner assemblies. | 05-27-2010 |
| 20100187780 | Snow Machine Ski - A ski for a snowmobile or other snow machine is provided with a pair of lateral wings and a central channel for increasing the flow of snow under a gliding surface at the bottom of the ski. The increased flow of snow enhances flotation of the ski. The channel may be formed by two downwardly extending keels. The wings are defined between the keels and outer edges of the ski. | 07-29-2010 |
| 20110042909 | SNOWMOBILE SKIS HAVING ELONGATED WING MEMBERS - Snowmobile skis include at least one elongated wing member projecting laterally outward and upward from a lateral side of a base portion of the ski. The at least one elongated wing member has a lower surface that extends vertically over and laterally outward from the lower running surface of the ski. At least a longitudinal section of the lower surface of the at least one elongated wing member may include a portion having a curved, concave shape. The lower surface of the at least one elongated wing member may extend a greater distance vertically over the lower running surface of the ski near a longitudinal midportion of the ski relative to a distance by which the lower surface of the at least one elongated wing member extends vertically over the lower running surface of the ski near a longitudinal front portion of the ski and near a longitudinal rear portion of the ski. | 02-24-2011 |
| 20110079970 | SNOWMOBILE SKI EDGE - The snowmobile ski edge includes a main body having a plurality of mounting holes formed on a mounting face of the main body and a plurality of raised, breaker rails formed on the opposite face of the main body. The breaker rails are spaced across the width of the main body and break up ice and snow in front of the snowmobile skis to easily form new paths, which substantially reduces darting. Each breaker rail is angled to form a leading breaking face and a trailing face extending towards the back of the main body. Carbide inserts are disposed in grooves on both the breaking and trailing faces to strengthen and increase wear characteristics of the breaker rails. The main body includes sloping sides, which together with the breaker rails form channels to funnel broken ice and snow towards the back and reduce drag. | 04-07-2011 |

The steering ski comprises at least one keel blade typically removably mounted to the body and downwardly extending from the bottom surface and generally extending longitudinally along at least a portion of the bottom surface. The bottom surface is further slightly upwardly arched, generally along the central portion thereof, such that the bottom surface defines a generally front pressure zone and a generally rear pressure zone. The rear pressure zone is located longitudinally behind the at least one keel blade, and is configured for substantially filling the trace(s) formed in the snow by the at least one keel blade such that the steering ski leaves little or no trace(s) in its wake. | 09-05-2013 |
