Laminated Or Synthetic Material Patents (Class 280/610)
  • Patent number: 10137357
    Abstract: A skateboard deck that has a reduced weight, improved strength, and is, overall, more resilient. The addition of composite laminate layers improves the strength and performance of the skateboard. A composite layer may include carbon fiber layers, which are used to reduce the weight and thickness of the skateboard, while increasing the resilience and strength. Layered, high-strength tipfills and layered side edges may prevent chipping and delamination. The composite layers may inlay into the tipfills and side edges, allowing for protection of the composite layers. The tipfills and side edges protect the various other layers and prevent normal wear from abrasion, chipping, and delamination of the deck.

  • Patent number: 9802106
    Abstract: A sports board comprises, at a minimum, a top layer, a bottom layer, and a core in between them. A structural element with puzzle piece shape fits into a correspondingly shaped seat formed by the core, in between the top and bottom layers. The shape of the structural element prevents the structural element from being dislodged by shock forces frequently associated with use of the board. Machined or molded features are provided that penetrate or partially penetrate the structural element. These features, which are filled or included with resin, adhesive or another chemical bonding agent, resist horizontal shearing between the structural element, the core, and the top and bottom layers. A leading portion of the structural element protrudes out from in between the top and bottom layers, forming a bumper that acts as the first point of contact between the board and the ground or an obstacle.

  • Patent number: 9539488
    Abstract: A design for snowsports devices such as skis and snowboards uses non-Newtonian materials. Non-Newtonian materials exhibit rate-sensitive characteristics, with stress vs. strain properties dependent on the rate of loading. The snowsports device with non-Newtonian materials has variable stiffness and damping, with both increasing according to an increased applied load-rate such that a single snowsports device exhibits soft flex characteristics under low applied load-rates, but stiffer flex characteristics under high applied load-rates. The flex of the snowsports device is self-adjusting, with no manual adjustment input required by a user. The non-Newtonian material may be incorporated into the structure of the snowsports device in a number of different ways, including in the core, in composite sheet layers, and other locations.

    Abstract: The present disclosure relates to snowboards and skis that include a pair of edges for each longitudinal side of the snowboard or ski. The edges are laterally spaced apart, with one edge being an outer edge and the other edge being an inner edge. The inner edge is positioned vertically lower than the outer edge. The inner edge generally engages the snow surface prior to the outer edge, and is thus a transitional edge. Transitional edges may be rounded edges. The top surface of dual-edges snowboards or ski include an inner portion flanked on each lateral side by a lateral offset. A portion of the inner portion is recessed relative to the lateral offsets. The outer edges are positioned on a base surface of the lateral offsets. The inner edges are positioned on a base surface that is below the interface between the lateral offsets and the inner portion.

By combining wavy composite laminae in various waveforms, offsets, angular orientations and material combinations, it is possible to provide axial, torsion, or shear properties equivalent to unidirectional materials but without the limitations related to fiber discontinuity, labor costs for fabrication, and weakness at seams where laminates overlap. By combining wavy composite layers with unidirectional crossplies, or by using woven mats with various fill fiber levels where the warp fibers are sinuously arranged, improved strength and damping is possible.

  • Patent number: 7708303
    Abstract: Though the sport of snowboarding is not new, it has taken many years to understand the specific characteristics which are required for making snowboards. There is better understanding of the dynamic bending properties needed for current riders, especially for the competition driven rider whose demands require boards with different tip, tail and middle characteristics. Early snowboard designers understood the use of snowboards as articles for gliding down a snow covered slope making long curving turns, where tips and tails would be as stiff as the middle core. But now, the boards are jumped into the air, launching from half pipes edges and sliding down steel rails, requiring different flex contours. Snowboards are now required to be very flexible yet elastic being required to bend convexly and concavely, yet springing back to their shape immediately, with some riders wanting stiff tips or soft tails or a combination of both.

    Abstract: The SNOTZ Snow Skis are made from synthetic space-age material that exceeds the performance of other skis that have been produced in the past. SNOTZ skis possess the strength and flexibility of a performance ski and weighs less than its closest rival. The base, Teflon, has been compared to the surface of ice which has proved to be very slippery. This factor makes the SNOTZ Skis one of the fastest skis on the ski slopes today. There is no need for preparation of the base with ski waxes since the Teflon base has no porosity to absorb the wax. Also, the ski base has good abrasive resistance to help prevent tears, scratches, and gouges that are randomly found on the surface of the snow.

  • Patent number: 7631883
    Abstract: The invention relates to a slider and a method of making the same. The slider comprises a bottom plate, an inner core, and a skin plate. The inner core has a bottom surface and a top surface, and is made of a foamed plastic. The bottom plate and the skin plate are bonded to the bottom surface and the top surface of the inner core, respectively, to form a laminate, and thus the inner core is sandwiched between the bottom plate and the skin plate. The bottom plate is a multi-layer structure, comprising a foamed plastic layer, an adhesive layer, a fabric layer, an ink layer, and a composite casting layer, which are laminated downward in order from the bottom surface of the inner core. The skin plate is also a multi-layer structure, comprising a foamed plastic layer, an adhesive layer, a film layer, a corona treatment layer and an ink layer, which are laminated upward in order from the top surface of the inner core.

  • Patent number: 7467806
    Abstract: The present invention relates to lightweight ski systems. One embodiment of the present invention relates to a lightweight ski stability system for improving performance while maintaining lightweight characteristics. The ski stability system includes a ski and one or more weighted members. One weighted member is positioned on the upper surface of the ski within 10 centimeters of the tip contact point. A second optional weighted member is positioned on the upper surface of the ski within 10 centimeters of the tail contact point. The contact points refer to a lengthwise position before the tip or tail laterally curve upward. The weighted members weigh at least 3% of the ski weight. The disposition of these weighted members at one or both of the contact points increases the rotational inertia characteristics of the lightweight ski while minimizing the resulting weight. A second embodiment of the present invention relates to a method of increasing the rotational inertia of a lightweight ski.
