Abstract
Abstract A structure for connecting a ski binding clamp to a ski, wherein one or more engagement members secured to the bottom part of a ski binding clamp are inserted into holding cavities of a corresponding number in a bracket secured to the top surface of a ski, after which the ski binding clamp is caused to move within the same horizontal plane as that of the ski, thus engaging the engagement members attached underneath thereof with engaging means provided in the bracket.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
109 words
An apparatus for connecting a ski-binding clamp to a ski comprising: a base plate attached to the bottom of said ski-binding clamp; engaging means connected to said base plate and extending downward therefrom for engaging with said ski; and bracket means embedded in the upper surface of said ski removably surrounding said engaging means for locking said engaging means to said ski when said base plate is rotated horizontally relative to the surface of the ski and of said bracket means and means on the ski and the base plate to prevent rotation of the base plate to thereby maintain the clamp in a fixed position on the ski.
Claim 2
Independent Claim
109 words
An apparatus for connecting a ski-binding clamp to a ski comprising: a base plate attached to the bottom of said ski-binding clamp; engaging means connected to said base plate and extending downward therefrom for engaging with said ski; and bracket means embedded in the upper surface of said ski removably surrounding said engaging means for locking said engaging means to said ski when said base plate is rotated horizontally relative to the surface of the ski and of said bracket means and means on the ski and the base plate to prevent rotation of the base plate to thereby maintain the clamp in a fixed position on the ski.
Claim 3
Dependent Claim
243 words
An apparatus as claimed in claim 1, wherein: said engaging means is comprised of: a vertical rod of circular cross-section attached beneath said base plate and extended downward therefrom, a circular plate concentrically, horizontally attached to the bottom of said vertical rod, and at least two peripherally projecting engagement pawls spaced from each other on the edge of said horizontal circular plate; and said bracket means has a circular opening in the top surface thereof of a diameter larger than the diameter of the circular plate with the engagement pawls attached thereon, and said bracket means is comprised of at least two engaging pawls spaced from each other at the edge of said circular opening extending into the center thereof and extending downward into said circular opening a distance less than the length of said vertical rod, said engaging pawls forming a central opening and pawl engagement openings spaced from each other along the perimeter of the central opening slightly larger than said horizontal circular plate with said engaging pawls attached thereto, whereby inserting said vertical rod with said horizontal circular plate with said engaging pawls attached thereto through the opening in the upper surface of said bracket means and rotating the base plate attached to said vertical rod horizontally with respect to said ski causes the engagement pawls of the horizontal circular plate to slide under the engagement pawls of the bracket means, thereby locking the base plate to the bracket means.
Claim 4
Dependent Claim
54 words
An apparatus as claimed in claim 2, wherein the thickness of said engagement pawls comprising said bracket means is sufficient to allow a snug fit with said engagement pawls attached to said horizontal circular plate at the end of said vertical rod when said rod is inserted into and rotated in said bracket means.
Claim 5
Dependent Claim
21 words
An apparatus as claimed in claim 2, wherein said bracket means is comprised of a light alloy metal such as aluminum.
Claim 6
Dependent Claim
28 words
An apparatus as claimed in claim 2, wherein the upper surface of said bracket means embedded in said ski is flush with the upper surface of said ski.
Claim 7
Dependent Claim
175 words
An apparatus as claimed in claim 1, wherein: said engaging means is comprised of: a first and a second vertical rod spaced from each other attached to said base plate and extending downward therefrom, a first horizontal rod attached at a right angle to the bottom of said first vertical rod, and a second horizontal rod attached at a right angle to the bottom of said second vertical rod in the direction opposing the direction of said first horizontal rod; and said bracket means is hollow, has an opening in the top surface thereof and is comprised of a span rod positioned beneath said top surface of said bracket a distance less than the length of said vertical rods and spanned across said opening, whereby inserting said vertical rods into said opening, one vertical rod on either side of said span rod, and rotating said base plate horizontally with respect to said ski surface will cause said opposing horizontal rods to slide under said span rod, thereby locking said base plate to the bracket means.
Claim 8
Dependent Claim
37 words
An apparatus as claimed in claim 6, wherein said span rod in said opening is positioned a sufficient distance beneath the surface of the bracket means to form a snug fit with the horizontal rods slid thereunder.
Claim 9
Dependent Claim
21 words
An apparatus as claimed in claim 6, wherein said bracket means is comprised of a light alloy metal such as aluminum.
Claim 10
Dependent Claim
28 words
An apparatus as claimed in claim 6, wherein the upper surface of said bracket means embedded in said ski is flush with the upper surface of said ski.
Claim 11
Dependent Claim
26 words
An apparatus as claimed in claim 1, wherein said base plate has at least one screw hole therethrough for screwing said base plate to said ski.
