Abstract
A ski in which one or more additional masses of inertia are added to change the characteristics of the ski. A front additional mass of inertia is located substantially at a front transverse line of contact of the bottom surface of the ski with the ground. A rear additional mass of inertia may be located substantially at a rear transverse line of contact with the ground.
Claims16
A ski having a longitudinal axis, said ski comprising:
- a) an upper and lower surface;
- b) a front end which is turned upwardly;
- c) said lower surface including a contact surface for contacting the ground which is connected to said front end at a front transverse line of contact, the front transverse line of contact being defined at the position at which the unloaded ski contacts a sliding surface, said front transverse line of contact being transverse to said longitudinal axis;
- d) said ski having an average density, a discrete front additional mass of inertia being substantially centered about said front transverse line of contact, so that said front additional mass of inertia is distributed on both sides of a vertical plane including said front transverse line of contact, said front additional mass of inertia being non-viscous and having a greater density than said average density of said ski;
- and
- e) said front additional mass of inertia comprising two half-masses, said two half-masses being positioned, respectively, on both sides of a plane passing through said longitudinal axis;
- whereby the moment of inertia of the ski is affected by said front additional mass of inertia, both about a vertical axis and a horizontal axis, which is perpendicular to said longitudinal axis.
In a ski having an upper and lower surface, side edges, an internal core, and average density, a longitudinal axis, and a front end which is turned upwardly, said lower surface including a contact surface for contacting the ground, said contact surface being connected to said front end at a front transverse line of contact, said front transverse line of contact being transverse to said longitudinal axis and being defined at the position at which the unloaded ski contacts a siding surface, the improvement comprising a discrete front additional mass of inertia being substantially centered about said front transverse line of contact, so that said front additional mass of inertia is distributed on both sides of a vertical plane including said front transverse line of contact, said front additional mass of inertia being non-viscous and having a greater density than said average density of said ski, and said front additional mass of inertia including two half-masses being positioned, respectively, on both sides of a plane passing through said longitudinal axis;
- whereby the moment of inertia of the ski is affected by said front additional mass of inertia, both about a vertical axis and a horizontal axis, which is perpendicular to said longitudinal axis.
