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.

A ski includes an elongate core and a fiber reinforced composite layer disposed over the elongate core. The fiber reinforced composite layer has a first plurality of fibers fixed in a resin and a second plurality of fibers fixed in the resin. The first plurality of fibers extend along a first arcuate path from a left side of the ski to a right side of the ski such that the angle of the first fibers with respect to the centerline increases from the left side to the right side. The second plurality of fibers extend along a second arcuate path from the right side of the ski to the left side of the ski such that the angle of the second fibers with respect to the centerline increases from the right side to the left side. In some embodiments the first and second plurality of fibers are symmetrically positioned in the composite layer.

A ski, wherein the ski includes: a ski core; a ski coating which forms an underside of the ski; a lower flange which is arranged between the ski core and the ski coating; steel edges; and side walls; wherein the lower flange includes at least a front region and/or a rear region which is broader, in a direction transverse to a longitudinal axis of the ski, than a distance between the steel edges in the direction transverse to the longitudinal axis of the ski in the region.

A sliding board, preferably a snow sliding board, including: a front sliding board region including a front end of the sliding board; a rear sliding board region including a rear end of the sliding board; and a binding region, extending between the front sliding board region and the rear sliding board region in the longitudinal direction of the sliding board, for fixing a sliding board binding for holding a boot. The snow sliding board exhibits a multi-layered structure including at least: a sliding board core; upper layers which are arranged above the sliding board core; and lower layers which are arranged below the sliding board core. At least one of the upper layers and/or at least one of the lower layers includes a fiber-composite material, wherein the fiber-composite material includes a multitude of fibers, wherein the fiber-composite material in a region exhibits a fiber orientation which varies within the region.

The present invention is directed to an apparatus for travel upon ice, snow, or similar low-friction inducing surface to mimic the activity of skateboarding. The present invention uses a pillar component disposed between a deck and base for the interconnection and support of the base and deck.

A system, method and apparatus for a digitally Controlled Variable Stiffness item of athletic equipment, such as a Ski, Snowboard, and Boots. A core of thermally responsive metal alloy, such as Nitinol is disposed within the athletic equipment. A thermal control module and controller permit the athlete to program the athletic equipment to a desired stiffness parameter. The controller may include an app operable via a mobile computing device in communication with the thermal control module.

A foam product includes a foam core, a soft skin covering the foam core, and a base structure on which the foam core is disposed. The foam core of expanded beads has an outer surface on which some outermost beads of the expanded beads are exposed and bulging outward with different heights to form a bubbly texture. The foam skin has an inner surface attached to the outer surface of the foam core, and has at its inner surface a plurality of concave cavities each matedly surrounding a respective one of the bulging, outermost beads on the outer surface of the foam core.

A method of manufacturing a snow sliding device includes forming a core by forming a core body including an outer surface including an upper surface, a lower surface, and a first thickness, and shaping the core body to include a second thickness; providing a plurality of elements, including a base with a sliding surface, and a top surface; incorporating in at least one of the core and the plurality of elements a first material, the first material exhibiting a shear rate-dependent shear resistance; and laminating the plurality of elements to the core.

The invention relates to a ski, including: a paddle region which forms a front end of the ski; a rear end region; and a binding region, which extends in the longitudinal direction of the ski between the paddle region and the rear end region, for fastening a ski binding; a core; an upper strap; a lower strap; and a reinforcing frame which extends in the paddle region and/or in the rear end region.

A snow and water sport sliding device with a pneumatic core and method of manufacturing the device. The device includes a top layer comprising a front tip, a middle segment with a binding plate, and a back segment with an adjustable air valve. Top layer may also include a blade spring system. The device also includes a main core component layer under the top layer that comprises of a hollow air chamber, and a base layer. Base layer may include embedded metal edge.
