Abstract
Abstract A rigid member shaped to engage a substantial surface area of a person''s shin is positionable between the person''s shin and the front surrounding rigid leg portion of a ski boot, there being provided a bearing or fulcrum point between the member and the inside portion of the rigid leg portion of the ski boot. The arrangement permits tilting of the member about the fulcrum point to follow the tilting of a person''s shin when leaning forward or rearwardly and distributes forces concentrated at the fulcrum point over a large area of the person''s shin thereby avoiding point contact of the upper rigid portion of the boot with the person''s shin and resulting pain and risk of injury.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
119 words
In combination: a. a ski boot including a foot portion and rigid cylindrical leg portion; b. a vertically elongated rigid member transversely curved and tapering in width in a downward direction to conform to the front of a person''s shin and thereby engage the same over a substantial surface area; and c. bearing means between the front portion of said member intermediate its upper and lower ends, and an inside portion of said rigid cylindrical leg portion, said bearing means defining a fulcrum about which tilting of said member can take place whereby forces concentrated at said fulcrum resulting from a leaning forward of a person''s leg in the boot are distributed by said member over said surface area.
Claim 2
Dependent Claim
119 words
In combination: a. a ski boot including a foot portion and rigid cylindrical leg portion; b. a vertically elongated rigid member transversely curved and tapering in width in a downward direction to conform to the front of a person''s shin and thereby engage the same over a substantial surface area; and c. bearing means between the front portion of said member intermediate its upper and lower ends, and an inside portion of said rigid cylindrical leg portion, said bearing means defining a fulcrum about which tilting of said member can take place whereby forces concentrated at said fulcrum resulting from a leaning forward of a person''s leg in the boot are distributed by said member over said surface area.
Claim 3
Dependent Claim
30 words
The combination of claim 1 in which said member includes means for adjusting the vertical position of said bearing means relative to the upper and lower ends of the member.
Claim 4
Dependent Claim
29 words
The combination of claim 1, in which said rigid cylindrical leg portion includes means for vertically adjusting the position of the inside portion thereof engaged by said bearing means.
Claim 5
Dependent Claim
135 words
The combination of claim 1, in which said bearing means includes a conical element having an axial hole, the front of said member including a threaded hole over which said conical element is positioned, the inside portion of said rigid cylindrical leg portion having an exit opening of diameter less than the base diameter of said conical element and greater than the axial hole passing therethrough; and a screw insertable from the outside front portion of said rigid cylindrical leg portion through said opening and said hole in said conical element to be threadedly received in said threaded hole, said screw having an enlarged head greater in diameter than said opening whereby fulcrum action of said bearing means takes place between the peripheral surface of said conical element and the exit end of said opening.
