Abstract
A sled for sliding on a sliding surface has a hull with bow and stern ends, a side portion extending therebetween, and a bottom surface for contacting the sliding surface. A snow-brake integral with the hull is formed from a portion of the hull that extends outward from the hull and downward part-way to the bottom surface. The snow-brake forms a scoop for engaging the sliding surface when an angle between the hull and the sliding surface exceeds a critical angle. The critical angle is selected such that the bottom surface contacts the sliding surface while the snow-brake engages the sliding surface.
Claims7
A sled for sliding on a sliding surface, the sled comprising
- a hull having
- a bow end,
- a stern end having a curved portion, the bow end and the stern end defining a longitudinal axis extending therebetween;
- a bottom surface for contacting the sliding surface a gunwale portion having a portion that extends downward part-way to the bottom surface;
- and
- a snow-brake integral with the hull, the snow-brake being formed from said gunwale portion of the hull that extends outward from the gunwale and downward part-way to the bottom surface, the snow-brake forming a scoop and wraps around a the gunwale portion at the stern end such that the scoop engages the sliding surface when an angle between the hull and the sliding surface exceeds a critical angle and when the sled travels in a direction that differs from the longitudinal axis, the critical angle being selected such that the bottom surface contacts the sliding surface while the snow-brake engages the sliding surface.
