    Abstract: A torsionally-damped ski having a durable, low friction ski base and non-rusting durable ski edges that have exceptional edge-retaining qualities, including an elongated snow-contacting base surface made of a Nitinol sheet having two opposed longitudinal edges on opposite sides of an elongated medial portion. A Nitinol ski edge structure extends longitudinally along both of the edges of the sheet, having a greater thickness than the medial portion of the sheet. The edge structures form an integral part of the Nitinol base sheet by welding the sheet along opposite edges thereof to the edge structures. Preferably, the ski edge structure is Type 60 Nitinol. The base sheet can be superelastic Nitinol or Martensitic Nitinol having shape memory characteristics. A torsional vibration structure is built into the ski, including Nitinol structures extending along one or more axes lying oblique to the longitudinal axis of the ski.

  • Patent number: 6095547
    Abstract: A board, such as a ski or snowboard, that includes a piezoelectric damper. A sensor such as a piece of piezoelectric material is located on the body of the board such that, as the board vibrates or deforms, the piezoelectric sensor is also deformed. As the piezoelectric sensor deforms, it produces an electrical signal that is provided to a control circuit. The control circuit receives the electrical signal and generates a control signal of proportional amplitude and frequency, but an inverse waveform to the sensed vibration. The control signal causes a piezoelectric damper to stiffen and resist deformation of the board, thus damping the vibration. The sensed signal may also be stored within a memory device and subsequently downloaded to provide a skier profile for analysis.

    Abstract: A sliding board includes a device of the "stress plate" type, having a layer of viscoelastic material covered by a stress plate with a high elasticity modulus, the layer of viscoelastic material being joined to one outer surface of the sliding board and to the stress plate. According to the invention, the stress plate has at least one strip-shaped area that is not joined to the board over part of the width and part of the length of the plate, the strip being elastically flexible and being connected to the board by its ends so that when the board flexes, it behaves like a leaf spring acting mechanically by buckling between its two ends connected to the board.

  • Patent number: 5915717
    Abstract: A board for sliding on snow has a body extending over the entire length of the board and forming a tip and a heel at the ends of the board and at least one upper plate that extends and rests on at least part of the board, except at the tip and the heel. The upper plate is rigidly attached to either a middle, front or rear zone of the body. The base of the upper plate and the corresponding upper surface of the body having matching shaped projections and indentations at a portion of the upper plate that is not rigidly attached to the body. The matching projections and indentations are designed to convert a lengthwise sliding movement of the upper plate on the body into a force that includes a pressure component that is perpendicular to the surface of the sole.

  • Patent number: 5909894
    Abstract: A snowboard binding for securing a snowboard boot to a snowboard that includes a rigid baseplate, a strap, and an isolation member. The rigid baseplate includes sidewalls and a heel loop extending upwardly therefrom. The baseplate is adapted for attachment to the snowboard and includes a plurality of isolation apertures extending therethrough. A disk aperture is also provided for receiving an attachment disk for fastening the baseplate to the snowboard. The strap is connected to the sidewalls of the baseplate for releasably securing the boot to the binding. The isolation member is formed from a unitary substantially elastic, rubbery material. The isolation member extends beneath the baseplate to substantially isolate the baseplate from the snowboard. The isolation member has a plurality of upward projections extending through the isolation apertures in the baseplate. The upward projections have T-shaped cross sections with head and neck portions.

  • Patent number: 5895067
    Abstract: A ski having a tip region, a heel region, and a central zone, is provided with a running sole having longitudinal sides and a longitudinal axis, an edge formed on each of the sides of the running sole, and an upper face including at least two side faces being non-parallel to the running sole. The at least two side faces intersect each other above the running sole to create an apex extending longitudinally over at least part of the ski. The apex is asymmetrical with respect to a longitudinal mid-plane through the longitudinal axis of the running sole.

  • Patent number: 5884932
    Abstract: A sliding device, in particular a ski, comprises a sliding body and means on the sliding body for controlling vibration thereof. The controlling means comprises at least one sequence of a plurality of spatial, planar or linear areas, each of which is distinguished from at least a part of its vicinity by at least one differently dimensioned or distributed vibration parameter. The center distances between subsequent distinguished areas, or the distances between certain sections within subsequent distinguished areas, is dimensioned according to at least one predetermined increasingly or decreasingly varying progression. The increasingly or decreasingly varying distances are configured such that the areas establish a vibration active structure of the sliding body with a plurality of natural or resonant frequencies.

  • Patent number: 5857694
    Abstract: A sports implement including an electroactive element, such as a piezoceramic sheet attached to the implement and a circuit attached to the electroactive element. The circuit may be a shunt, or may include processing such as amplification and phase control to apply a driving signal which may compensate for strain sensed in the implement, or may simply alter the stiffness to affect performance. In a ski, the electroactive element is located near to the root in a region of high strain to apply damping, and the element captures between about one and five percent of the strain energy of the ski. The region of high strain may be found by modeling mechanics of the sports implement, or may be located by empirically mapping the strain distribution which occurs during use of the implement. In other embodiments, the electroactive elements may remove resonances, adapt performance to different situations, or enhance handling or comfort of the implement.

  • Patent number: 5855389
    Abstract: A snowboard having a forward end with a shovel and rearward end with a heel. The forward shovel and rearward heel include forward and rearward contact areas on both the right and left sides. The snowboard includes a base sheet, a core, a top sheet, forward and rearward binding fastening regions, and a first reinforcement member. The core is disposed above the base sheet. The top sheet is disposed above the core. The forward and rearward binding fastening regions are disposed between the shovel and heel. The first reinforcement member is disposed between the core and the top sheet and extends from adjacent one of the forward and rearward binding fastening regions to adjacent both contact areas on one end of the snowboard. The first reinforcement member includes a right leaf spring member and a left leaf spring member. The right leaf spring member extends generally from the binding fastening region toward the right contact area.
