Abstract
Abstract A ski-mounting assembly for snow vehicles and the like comprising a conventional shock absorber and a rigid arm member disposed longitudinally in line with each other above the ski, the shock absorber and the arm members being connected at the outer ends thereof to the ski by fixed pivots, and being interconnected at the inner ends thereof by a movable pivot, the shock absorber and the arm member extending angularly upwardly toward each other from the fixed pivots at a relatively flat angle with respect to the ski, the arm member being supported by a coil spring preferably disposed substantially at the center of the ski, and means being provided on the arm member preferably directly over the spring for attaching the assembly to the snow vehicle.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
134 words
A ski mounting for snow vehicles and the like comprising load-supporting means including a shock absorber, a rigid arm member, a first fixed pivot mounting connecting one end of said shock absorber to said ski member adjacent to end of the latter, a second fixed pivot mounting connecting one end of said rigid arm member to said ski member adjacent to the other End of the latter, and movable pivot means interconnecting the other end of said shock absorber and said rigid arm member; coil spring means interposed between said load supporting means and a seat on said ski member intermediate said first and second fixed pivot mountings and proximate to said movable pivot means; and connecting means associated with said load-supporting means for use in attaching said ski mounting to a snow vehicle.
Claim 2
Dependent Claim
134 words
A ski mounting for snow vehicles and the like comprising load-supporting means including a shock absorber, a rigid arm member, a first fixed pivot mounting connecting one end of said shock absorber to said ski member adjacent to end of the latter, a second fixed pivot mounting connecting one end of said rigid arm member to said ski member adjacent to the other End of the latter, and movable pivot means interconnecting the other end of said shock absorber and said rigid arm member; coil spring means interposed between said load supporting means and a seat on said ski member intermediate said first and second fixed pivot mountings and proximate to said movable pivot means; and connecting means associated with said load-supporting means for use in attaching said ski mounting to a snow vehicle.
Claim 3
Dependent Claim
45 words
The combination as set forth in claim 1 including means on the ski for supporting and retaining the lower end of said spring, and wherein the upper end of said spring is confined and retained in recess means in the underside of said load-supporting means.
Claim 4
Dependent Claim
31 words
The combination as set forth in claim 1 wherein the end of said spring means which seats on the ski member is disposed at substantially the center of said ski member.
Claim 5
Dependent Claim
58 words
The combination as set forth in claim 1 wherein the end of said spring means which seats on the ski member is disposed at substantially the center of said ski member, and wherein said connecting means is mounted on said rigid arm member directly above said spring means, whereby to position said spring normally vertically on said ski.
Claim 6
Dependent Claim
58 words
The combination as set forth in claim 1 wherein said rigid arm member extends from said second fixed pivot at a relatively flat angle with respect to said ski member, and wherein said load-supporting means has an essentially low silhouette to minimize the vertical height of the ski-mounting assembly and to facilitate placement thereof under said snow vehicle.
Claim 7
Dependent Claim
20 words
The combination as set forth in claim 1 wherein said rigid arm member is relatively longer than said shock absorber.
Claim 8
Dependent Claim
45 words
The combination as set forth in claim 6 wherein the end of said spring means which seats on the ski member is disposed at substantially the center of said ski member and relatively closer to said first fixed pivot than to said second fixed pivot.
Claim 9
Dependent Claim
26 words
The combination as set forth in claim 1 wherein said spring means is disposed directly under said rigid arm member adjacent to said movable pivot means.
Claim 10
Dependent Claim
34 words
The combination as set forth in claim 8 including a resilient bumper interposed between said ski member and said rigid arm member and engageable with the latter under extreme load conditions of said spring.
Claim 11
Dependent Claim
33 words
The combination as set forth in claim 9 wherein said resilient bumper is disposed inside said spring means and under the end of said rigid arm member adjacent to said movable pivot means.
Claim 12
Dependent Claim
144 words
A mounting for the ski of a snow vehicle comprising load-supporting means including a shock absorber, and a rigid arm member, said shock absorber and said rigid arm member being pivotally connected to each other; and a coil spring positionable under said load supporting means at substantially the point of pivotal connection between said shock absorber and said rigid arm member, the outer ends of said shock absorber and said rigid arm member adapted for pivotal attachment to said ski with the point of pivotal interconnection spaced above the ski so that said point of pivotal interconnection is free to move vertically relative to the ski as the shock absorber expands and contracts in use, and said spring adapted to be interpositioned in a normally vertical position between said load-supporting means and said ski to control vertical movement of said point of pivotal interconnection.
Claim 13
Dependent Claim
144 words
A mounting for the ski of a snow vehicle comprising load-supporting means including a shock absorber, and a rigid arm member, said shock absorber and said rigid arm member being pivotally connected to each other; and a coil spring positionable under said load supporting means at substantially the point of pivotal connection between said shock absorber and said rigid arm member, the outer ends of said shock absorber and said rigid arm member adapted for pivotal attachment to said ski with the point of pivotal interconnection spaced above the ski so that said point of pivotal interconnection is free to move vertically relative to the ski as the shock absorber expands and contracts in use, and said spring adapted to be interpositioned in a normally vertical position between said load-supporting means and said ski to control vertical movement of said point of pivotal interconnection.
Claim 14
Dependent Claim
39 words
The combination as set forth in claim 11 including connecting means affixed to said rigid arm member substantially above the mounting location for said spring and adapted to attach said ski mounting to the body of said snow vehicle.
