A system, configuration, and method for converting a pair of skis to perform as an emulation snowboard is provided. The system includes a pair of skis, and a coupling device including a platform having an upper planar surface with a plurality of mounting locations with mounting system therein. The mounting system couples the skis together and provides a surface on which a pair of bindings may be affixed. The steps for conversion include providing a pair of skis, removing a ski binding from each ski in the pair of skis, if a binding is installed on either ski in the pair of skis, providing a platform with a mounting system, utilizing the mounting system to affix the platform to each ski in the pair of skis, and attaching a pair of snowboard bindings to the platform.

A ski may define a body that defines a tip, a tail opposite the tip, a top sheet, a base extending from the tip to the tail and opposite the top sheet, a core layer positioned between the base and the top sheet, and a reinforcement layer positioned between the top sheet and the base. The reinforcement layer defines an aperture extending through the reinforcement layer and positioned within a first third of a length of the ski, the length defined from the tip to the tail.

A snowboard, snowboard assembly, and snowboard accessory for converting a snowboard into training snowboard. There is a board and a pivot member/strip. The pivot member/strip is elongated member protruding from the underside of the board along the main axis of the board. The pivot member/strip has a base width that is greater than a width of the flat bottom of the strip and greater than a height of the strip. The flat bottom of the strip is flanked by beveled edges along each side and at the front and back. The strip is either integral to the board or is couple thereto by a coupling structure (e.g. adhesive, binding, snaps, clips). The strip has a trapezoidal cross-section. Flanking beveled edges may have an acute angle with respect to the base and/or an obtuse angle with respect to the flat bottom surface.

Embodiments are directed towards a helmet adapted for use by a human being for a variety of activities. The helmet includes a shell, a plurality of FAEs, and at least one rigid component. The shell maybe configured and arranged to cover a portion of a wearer's head. The plurality of FAEs may be separately positioned adjacent to the shell's interior surface. Each FAE may include at least one disc spring that is adapted for absorbing forces. The at least one rigid component may be disposed within the shell and adjacent to the plurality of FAEs. In this way, the FAEs may be between the shell's interior surface and the at least one rigid component. When a force is applied to a location on the shell's exterior surface, it may be substantially absorbed by at least one of the FAEs positioned adjacent to the location on the shell's interior surface.

The present invention relates to a snow gliding device comprising: a first gliding surface, a first layer for heating said first gliding surface, which first layer comprises: a positive temperature coefficient superimposed impedance polymeric compound, a first and a second electrode, wherein said positive temperature coefficient superimposed impedance polymeric compound is at least partially sandwiched between said first and second electrode, and which first and second electrodes are adapted to provide a potential difference across said positive temperature coefficient superimposed impedance polymeric compound when connected to a power source, which first layer is arranged adjacent to and in thermal communication with said first gliding surface.

A sporting equipment is disclosed. The sporting equipment may include a barrel, an action connected to a base end of the barrel, and a stock connected to the action opposite the barrel. At least two of the barrel, the action, and the stock are fabricated from a plurality of fibers.

A foam product includes a foam core, an upper skin and a lower skin. The foam core has a top surface, a bottom surface, and a peripheral side surface. The upper skin covers both of the top surface and the peripheral side surface of the foam core, but extending not beyond the bottom surface of the foam core. And, the lower skin covers both of the bottom surface of the foam core and a peripheral end surface of the upper skin.

Provided are a sliding instrument having a low frictional resistance to the snow surface, the ice surface, or the water surface and having excellent sliding performance and a method for manufacturing the sliding instrument. A sliding instrument to slide on snow, ice, or water includes a sliding surface (1) to come into contact with the snow surface, the ice surface, or the water surface, and the sliding surface (1) has a surface roughness Ra of 1.0 m or less. A method for manufacturing the sliding instrument includes polishing a sliding surface (1) using a polishing composition slurry containing abrasives to make the sliding surface (1) have a surface roughness Ra of 1.0 m or less.
