Abstract
Abstract A device for determining the bias or angle between the bottom of the sole of a ski boot and the wearer''s knee. A flat base plate includes nub extensions centrally located on the underside and a rigid wand extending upwardly from one end thereof. When the wearer places the boot on the base plate, any bias will be indicated by the angle between the longitudinal centerline of the wand and the wearer''s knee. Auxiliary clamping means may be added to the wand to check the accuracy of the subsequent correction of the boot sole.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
172 words
A device for measuring the lateral bias of a ski boot, while being worn, relative to the knee position comprising an elongated rigid plate member having an upper planar surface, said upper surface being of sufficient length to substantially subtend the sole of a ski boot placed longitudinally thereof; a wand extending substantially at right angles from said planar surface and secured to one end of said upper surface, said wand being of at least a length approximate to that of the knee to foot leg portion of a ski boot wearer; extension means secured to the lower surface of said plate member for supporting said plate member along its longitudinal axis, said plate member being pivotable about said longitudinal axis in response to the lateral bias of a ski boot aligned longitudinally of said plate member so as to measure said lateral bias as indicated by the angle between the pivoted position of the wand and a line extending from the knee to the longitudinal axis created by said extension means.
Claim 2
Independent Claim
172 words
A device for measuring the lateral bias of a ski boot, while being worn, relative to the knee position comprising an elongated rigid plate member having an upper planar surface, said upper surface being of sufficient length to substantially subtend the sole of a ski boot placed longitudinally thereof; a wand extending substantially at right angles from said planar surface and secured to one end of said upper surface, said wand being of at least a length approximate to that of the knee to foot leg portion of a ski boot wearer; extension means secured to the lower surface of said plate member for supporting said plate member along its longitudinal axis, said plate member being pivotable about said longitudinal axis in response to the lateral bias of a ski boot aligned longitudinally of said plate member so as to measure said lateral bias as indicated by the angle between the pivoted position of the wand and a line extending from the knee to the longitudinal axis created by said extension means.
Claim 3
Dependent Claim
23 words
The device of claim 1 further comprising means for centering said boot longitudinally along said plate member and substantially perpendicular to said wand.
Claim 4
Dependent Claim
32 words
The device of claim 1 wherein said means for securing said wand to said plate member comprises a hinge whereby said wand may be angularly moved with respect to said plate member.
Claim 5
Dependent Claim
26 words
The device of claim 3 wherein the longitudinal centerline of said wand lies in the same plane as the longitudinal centerline of said rigid plate member.
Claim 6
Dependent Claim
21 words
The device of claim 3 further comprising adjustable means movably secured to said wand for aligning said wand with said knee.
Claim 7
Dependent Claim
33 words
The device of claim 4 wherein said adjustable means comprises a U-shaped member adjustable vertically along said wand and laterally so as to vary the distance between the legs of said U-shaped member.
Claim 8
Dependent Claim
22 words
The device of claim 1 wherein said extension means comprises a plurality of nubs spaced along the centerline of said plate member.
Claim 9
Dependent Claim
19 words
The device of claim 1 wherein said wand comprises a rigid plate having a longitudinal center slot located therein.
Claim 10
Dependent Claim
29 words
The device of claim 2 wherein said means for centering said boot comprises a rigid guide secured to said plate including two arms extending angularly outwardly from said wand.
