Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
272 words
In a vehicle for supporting a rider in a generally upright position for traveling in snow or the like, the combination comprising: a member configured for supporting a rider in a generally upright position, said member being generally elongate and having a longitudinal center line; first and second truck members mounted on the under surface of said rider supporting member along said longitudinal center line, each of said truck members being substantially identical and having a stationary portion and a steering member pivotable relative to said stationary portion; a first ski member secured to the steering member of said first truck member; a second ski member secured to the steering member of said second truck member, said first and second ski members being generally broadly dimensioned for distributing the weight of the rider over a relatively broad area tilting of the plane of said rider supporting member relative to the surface engaged by said first and second ski members pivoting said first and second ski members relative to each other whereby to provide steering, and said rider supporting member is an elongate generally board-like member and includes strap means secured thereto on the longitudinal center line thereof for defining first and second foot receiving openings, wherein said strap means is a generally flexible elongate strap member having a first end secured to one end of said board-like member, said board member is provided with first and second parallel slots extending generally transverse to the longitudinal center line thereof for passage therethrough of said strap member, the other end of said strap member being secured to the other end of said board-like member.
Claim 2
Dependent Claim
272 words
In a vehicle for supporting a rider in a generally upright position for traveling in snow or the like, the combination comprising: a member configured for supporting a rider in a generally upright position, said member being generally elongate and having a longitudinal center line; first and second truck members mounted on the under surface of said rider supporting member along said longitudinal center line, each of said truck members being substantially identical and having a stationary portion and a steering member pivotable relative to said stationary portion; a first ski member secured to the steering member of said first truck member; a second ski member secured to the steering member of said second truck member, said first and second ski members being generally broadly dimensioned for distributing the weight of the rider over a relatively broad area tilting of the plane of said rider supporting member relative to the surface engaged by said first and second ski members pivoting said first and second ski members relative to each other whereby to provide steering, and said rider supporting member is an elongate generally board-like member and includes strap means secured thereto on the longitudinal center line thereof for defining first and second foot receiving openings, wherein said strap means is a generally flexible elongate strap member having a first end secured to one end of said board-like member, said board member is provided with first and second parallel slots extending generally transverse to the longitudinal center line thereof for passage therethrough of said strap member, the other end of said strap member being secured to the other end of said board-like member.
Claim 3
Dependent Claim
48 words
The combination according to claim 1 wherein said second ski member is the rear ski member and the rear portion thereof is provided with a transversely extending flange portion configured for engaging the snow upon shifting of the weight of the rider rearwardly whereby to slow the vehicle.
