Abstract
Abstract An improved snow ski comprising a rigid core, downwardly extending running edges affixed to the core, a block of resilient material disposed between the running edges and affixed to the core, and a planar bottom member, slidably disposed between the running edges and affixed to the resilient block of material. During turning, the weight of the skier and centrifugal forces acting upon the ski compress the resilient block of material so that the bottom of the ski slides inwardly past the running edge of the ski disposed on the inside of the turn and the running edge protrudes past the bottom of the ski and engages the snow or ice on which the ski is moving.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
111 words
A snow ski, comprising: a rigid core; a pair of downwardly extending running edges, affixed to said core; a block of resilient material, disposed between said running edges, and affixed to said core; and a planar bottom member, slidably disposed between said running edges and affixed to said resilient block of material, whereby the weight of the skier and centrifugal forces acting upon the ski during turning cause said resilient block of material to compress and said bottom planar member to slide inwardly past at least one of said running edges so that said one edge protrudes past said bottom member and engages the snow on which the ski is moving.
Claim 2
Dependent Claim
111 words
A snow ski, comprising: a rigid core; a pair of downwardly extending running edges, affixed to said core; a block of resilient material, disposed between said running edges, and affixed to said core; and a planar bottom member, slidably disposed between said running edges and affixed to said resilient block of material, whereby the weight of the skier and centrifugal forces acting upon the ski during turning cause said resilient block of material to compress and said bottom planar member to slide inwardly past at least one of said running edges so that said one edge protrudes past said bottom member and engages the snow on which the ski is moving.
Claim 3
Dependent Claim
38 words
The ski as recited in claim 1, wherein said running edges each have an inclined lower edge extending upwardly and outwardly away from the center of the ski for engaging the snow on which the ski is moving.
Claim 4
Dependent Claim
47 words
The ski as recited in claim 2, wherein said running edges are L-shaped, and have one leg thereof affixed to said core and disposed substantially parallel to said bottom member of the ski, and the other leg thereof disposed perpendicular to said bottom member of the ski.
Claim 5
Dependent Claim
29 words
The ski as recited in claim 1, wherein said block of resilient material decreases in thickness along the length of the ski from the center to each end thereof.
Claim 6
Dependent Claim
55 words
The ski as recited in claim 1, further comprising a rigid support member, disposed between said running edges and affixed to said core, for engaging said bottom member of the ski, and wherein said block of resilient material comprises a pair of blocks of resilient material disposed adjacent said support member between said running edges.
Claim 7
Dependent Claim
39 words
The ski as recited in claim 5, wherein said running edges are provided with lower inclined surfaces extending upwardly and outwardly away from said bottom member of said ski for engaging the snow on which the ski is moving.
Claim 8
Dependent Claim
13 words
Te ski as recited in claim 6, wherein said running edges are L-shaped.
Claim 9
Dependent Claim
68 words
The ski as recited in claim 1, wherein said running edges are planar in shape, and further comprise lower incLined edges extending upwardly and outwardly away from said bottom member of the ski, said planar running edges forming the sides of the ski, and wherein the ski further comprises a planar top member, disposed between said running edges, and rigidly affixed thereto, forming the top of the ski.
