Abstract
A snowmobile ski comprising a longitudinally extending runner having a bottom surface, a generally flat elongate bar having a top and bottom surface, and a steering skag extending longitudinally of the runner on the bottom side of the bar. The flat bar is generally contoured to abut the bottom surface of the runner, and furthermore extends forwardly beyond the skag and laterally and longitudinally beyond the skag so that a skag track in the snow encountered by the ski and the skag track left by the skag in the snow will be at least partially filled in by the bar.
Claims16
A snowmobile ski comprising:
- a longitudinally extending runner having a bottom surface;
- a generally flat, elongate bar having top and bottom surfaces, the top surface being generally contoured to abut the bottom surface of the runner;
- a steering skag extending-longitudinally along the runner beneath the bar;
- and
- attachment means for attaching the skag and the bar to the ski;
- the bar extending laterally and longitudinally beyond the skag so that the track left by the skag in the snow will be at least partially filled in by the bar.
A snowmobile ski comprising:
- a longitudinally extending runner having a bottom surface and an upwardly curved forward end portion;
- a generally flat, elongate bar having top and bottom surfaces, the top surface being generally contoured to abut the bottom surface of the runner, and a tapered front end that is inserted into a complementary orifice in the runner;
- a steering skag with a generally circular cross section extending longitudinally of the runner on the bottom side of the bar, the skag being attached to the runner by a plurality of threaded rods that pass through slots in the bar and the runner, being secured to the runner by corresponding nuts;
- the bar extending laterally and longitudinally forwardly of and rearwardly beyond the skag to cover and protect at least a part of the bottom surface of the runner's forward curved portion from wear and so that the track left by the skag in the snow will be at least partially filled in by the bar and the bar will at least partially fill in a skag track in the snow encountered by the ski.
A snowmobile ski comprising:
- a longitudinally extending runner having a bottom surface and upwardly curved forward end;
- a generally flat, elongated bar having top and bottom surfaces and a front end portion, the top surface being generally contoured to abut the bottom surface of the runner, and the front end portion being tapered to a narrower width;
- and
- a steering skag secured to the runner and extending longitudinally along the runner;
- the bar being secured to the runner and extending laterally beyond the sides of the skag and longitudinally forward of the skag to cover and protect at least a part of the bottom surface of the runner's forward curved portion from wear and to at least partially fill a skag impression encountered by the ski.
A snowmobile ski, comprising:
- a longitudinally extending runner having a bottom surface;
- a steering skag secured to the runner and extending longitudinally along the runner;
- and
- a generally flat, elongate bar having top and bottom surfaces, the bar being wider than the skag and narrower than the runner, the bar being secured to the runner in a position so that at least a portion of the bar extends forwardly of the skag so that the bar will fill in a track encountered by the ski.
A snowmobile ski, comprising:
- a longitudinally extending runner having a bottom surface;
- a steering skag secured to the runner and extending longitudinally along the runner;
- a generally flat, elongate bar having top and bottom surfaces, the bar being secured to the runner and extending behind the skag so that the track left by the skag will be at least partially filled in.
