Abstract
Abstract A snow ski having adjustable camber-flattening resistance and characterized by a flat ski body having opposing side surfaces defining insert-receiving voids extending along the body mid-portion, and elongate body-stiffening inserts removably secured within the voids and providing with the body a particular camber-flattening resistance. A method for providing a ski having a desired camber-flattening resistance characterized by providing a flat ski body with the aforementioned voids defined in the side surfaces thereof, providing an array of inserts having differing stiffness characteristics but each being dimensioned for insertion in the voids, selecting a pair of inserts from the array, and securing such inserts in the voids. Preferred embodiments include inserts which may be used in one of two orientations to provide differing camber-flattening resistances.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
90 words
In a ski of the type having an elongate, substantially flat body with upper and lower surfaces, opposing side surfaces therebetween, and a foot-mounting mid-portion, the improvement comprising: the body having a resiliently flattenable camber; the opposing side surfaces defining insert-receiving voids extending along the body mid-portion; and elongate, body-stiffening inserts removably secured within the voids and providing with the body a particular camber-flattening resistance, said voids and inserts being dimensioned such that each insert is flush with its corresponding ski body side surface and is held by frictional engagement.
Claim 2
Dependent Claim
90 words
In a ski of the type having an elongate, substantially flat body with upper and lower surfaces, opposing side surfaces therebetween, and a foot-mounting mid-portion, the improvement comprising: the body having a resiliently flattenable camber; the opposing side surfaces defining insert-receiving voids extending along the body mid-portion; and elongate, body-stiffening inserts removably secured within the voids and providing with the body a particular camber-flattening resistance, said voids and inserts being dimensioned such that each insert is flush with its corresponding ski body side surface and is held by frictional engagement.
Claim 3
Dependent Claim
46 words
The ski of claim 1 wherein the inserts are dimensioned to allow insertion into the voids in either a first orientation providing a first camber-flattening resistance or a second orientation rotated 90° about the insert axis from the first orientation and providing a second camber-flattening resistance.
Claim 4
Dependent Claim
17 words
The ski of claim 2 wherein the inserts are of square cross-section at points along their length.
Claim 5
Independent Claim
103 words
A method for providing a cambered ski having a camber-flattening resistance approppriate for a given skier and/or ski conditions, comprising: providing an elongate, substantially flat, ski body with upper and lower surfaces, opposing side surfaces therebetween and a foot-mounting mid-portion, said side surfaces defining insert-receiving voids extending along the body mid-portion; providing an array of inserts having differing stiffness characteristics, the inserts and voids being dimensioned such that the inserts are removably frictionally secured in their corresponding voids and flush with their corresponding ski side surfaces; selecting a pair of inserts from the array; and securing such selected inserts in the insert-receiving voids.
Claim 6
Independent Claim
103 words
A method for providing a cambered ski having a camber-flattening resistance approppriate for a given skier and/or ski conditions, comprising: providing an elongate, substantially flat, ski body with upper and lower surfaces, opposing side surfaces therebetween and a foot-mounting mid-portion, said side surfaces defining insert-receiving voids extending along the body mid-portion; providing an array of inserts having differing stiffness characteristics, the inserts and voids being dimensioned such that the inserts are removably frictionally secured in their corresponding voids and flush with their corresponding ski side surfaces; selecting a pair of inserts from the array; and securing such selected inserts in the insert-receiving voids.
Claim 7
Dependent Claim
60 words
The method of claim 4 wherein the inserts are dimensioned to allow insertion into the voids in either a first orientation providing a first camber-flattening resistance or a second orientation rotated 90° about the insert axis from the first orientation and providing a second camber-flattening resistance, and wherein the inserts are secured in the voids in one of the orientations.
Claim 8
Dependent Claim
17 words
The method of claim 5 wherein the inserts are of square cross-section at points along their length.
