Patent ID: 7014206

Claim:
A ski having a sandwich-like or monocoque construction and including a mechanical system that modifies a radial geometry of the ski proportionally to a flexion of the ski, comprising: a rod including a substantially conical part on a first end thereof and a tension rod on a second end thereof; a slit stop attached to an upper surface of the ski including a substantially conical bore along an axis of the ski configured to receive the substantially conical part of the rod, and a length axis of the ski corresponding to the length of the ski along the direction of the rod, wherein the slit stop spreads apart when the rod, advances into the slit stop, wherein a radial geometry of a cross-section of a lower surface of the ski substantially perpendicular to the length axis is modified by the spreading of the slit stop, and wherein the rod advances into the slit stop because of a difference in a radius of the rod and a radius of the ski when the ski flexes.
