Abstract
A fixture and method for dynamically facilitating the optimum placement of a skier on the surface of skis. The fixture includes a pivotally mounted balance plate upon which the skis are positioned and the skier moves the boots to a dynamically neutral balance location so that when the skier flexes the upward and downward deflections of the ski tips can be controlled with equal ease.

A method of positioning a ski boot having a midsole mark thereon and a binding on a ski having a defined balance point and a prescribed binding mounting point at a dynamically neutral balance point comprising the steps of:
- a. placing the defined balance point of the ski on a pivot plate positioned to allow the ski tip to be pivoted upwardly and downwardly about an axis positioned in the plane of the ski and perpendicular to the longitudinal axis of the ski;
- b. temporarily positioning the skier, while wearing the ski boot, with the midsole mark of the ski boot of the skier aligned with the prescribed mounting point of the ski;
- c. pivoting the ski and boot combination about the pivot axis by the skier while standing on the ski to determine whether upward or downward movement of the ski tip is accomplished easier when flexing;
- and
- d. adjusting the positioning of the ski boot relative to the balance point of the ski and repeating method steps (c) and (d) until a dynamically neutral balance point is reached wherein downward and upward deflections of the tips of the skis may be accomplished by the skier with equal effort when flexing.
A fixture for accomplishing the optimum dynamic balancing of a pair of skis while being stood upon by the skier, the fixture comprising, in combinations:
- a. a frame;
- and
- b. platform having a pivot axis on a top surface thereof and mounted on the frame for deflection about the pivot axis by a skier standing on the platform with ski boots on a ski having the midpoint of the running surface thereof aligned with the pivot axis of the platform, the platform constructed and arranged for allowing the tips of the skis when the skier flexes to be deflected upwardly and downwardly by the skier with equal ease when the skier's boot is positioned at a dynamically neutral balance point on the surface of the ski.
A method for positioning a skier, a ski boot and a ski binding on a ski at a dynamically neutral balance point comprising the steps of;
- a. determining a midpoint of the running surface of the ski and positioning the ski for pivotal movement about a pivotal axis oriented transverse to the longitudinal axis of the ski and adjacent to the midpoint of the running surface of the ski;
- b. positioning the skier and boot at a beginning mounting position on the top of the ski in the vicinity of the midpoint of the running surface of the ski;
- c. moving the ski tips upwardly and downwardly by having the skier flex upwardly and downwardly in a normal skiing action and determining whether upward or downward movement of the ski tip is accomplished with less effort;
- d. adjusting the positioning of the skier, boot and binding relative to the beginning mounting position repetitively until a dynamically neutral balance point is reached wherein downward and upward deflections of the tips of the ski may be accomplished by the skier with equal effort when flexing;
- and
- e. mounting the bindings and boot to the skis at the location determined in step d.
