Nitinol ski structures

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.
