The running surface of a ski with unique individual tractive elements arranged in a pattern that allow for uphill movement by the skier. Individual tractive elements used on the running surface of a ski that have unique features in the surface design that enable more efficient operation for uphill movement by the skier. Individual tractive elements arranged in a pattern on a ski bottom in such a way that allows for minimum resistance to the snow surface in the glide portion of uphill ski movement, and maximum resistance in the grip (or kick) portion of uphill ski movement. Individual tractive elements that can be used uniquely on a ski bottom where a portion of the ski bottom surface is a device that can be removed and reattached. Individual tractive elements on the running surface of a ski bottom that can be arranged in a unique and optimal array to maximize the functions of uphill glide and uphill kick through movement of the skis by the skier. Individual tractive elements that can be incorporated on a climbing skin used in tractive uphill/forward skiing in a unique array configuration. Individual tractive elements in a unique array configuration that can be incorporated with additional tractive materials on a climbing skin used in tractive uphill/forward skiing.

Embodiments relate to a denticle scale array including a plurality of denticle scales arranged in pattern and configured to be incorporated onto a ski base, wherein the plurality of denticle scales includes at least a denticle scale including a glide contact area configured to contact terrain when the ski base is unweighted and moving forward, a kick contact area greater than the glide contact area and configured to contact the terrain when the ski base is weighted and not moving forward, at least a longitudinal profile comprising an S-curve, a curved trailing edge profile, and at least a longitudinal groove running parallel with the forward movement of the ski base.

An injection-molded ski includes a ski body and two ski edges attached to opposite edge surfaces of the ski body. The ski body is formed from a uniform material and has top, bottom, and edge surfaces and a binding mounting platform. The binding mounting platform is formed on the top surface and receives a boot binding. The ski edges comprise an edge portion and securing features. In one embodiment, a ski is injection-molded using a molding material, such as glass-reinforced nylon or a combination of one or more suitable materials. A novel mold facilitates injection of molding material around and/or between the securing features thereby locking the edges in place when the molding material cools. Compared to conventional skis, the novel injection-molded ski has improved durability, flexibility, strength, and performance characteristics, reduced manufacturing complexity that avoids typical layup processes, and reduced susceptibility to failure due to moisture or wear.

A snow ski assembly is provided for use by an individual to slide across a snow covered surface, for example, under the force of gravity. The assembly includes a ski having a bottom wall for engaging the snow covered surface and an upturned peripheral region extending around a perimeter of the bottom wall. The bottom wall of the ski includes at least one control structure extending across at least a portion of the bottom wall, where the at least one control structure is configured to control a movement of the ski on the snow covered surface. The assembly also includes a mounting feature configured to couple a binding to the bottom wall of the ski, such that the individual can position a foot in the binding and use the ski to slide across the snow covered surface.

A sports board incorporating reclaimed/reused sports board materials, and a method of making a such a sports board, allows for incorporation of portions of used (recycled) composite sports boards (or waste from the manufacture thereof) into new sports boards. This lessens the accumulation of composite sports board waste in the global environment, reduces the quantity of new virgin materials needed in the manufacture of new composite sports boards, and lessens the environmental impact of composite sports board manufacture and use. Optionally, the reclaimed sports board material may be incorporated into a new sports board in a manner providing structural enhancements (e.g., increased regional stiffness) to new sports boards. This may allow for structural enhancement while avoiding a significant increase in sports board weight, by incorporating used composite materials into new composite sports boards.

The present invention relates to a process of manufacturing skiing equipment using a high-entropy alloy, especially manufacturing for a bottom member of a ski, a blade of an ice skate shoe or the bottom member of a skiing vehicle. The high-entropy alloy is used to prepare skiing equipment, so that the skiing equipment has a small friction coefficient, obtains good speed, and can be driven with less energy, which realizes energy-saving effect.
