Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
223 words
A ski-turn simulator comprising: (a) an elongated rigid body having two ends and a principal axis therebetween, (b) first and second cross members attached to said elongated rigid body and extending laterally therefrom on both sides, (c) first and second footrests carried by said first and second cross members and pivotally connected thereto for rocking motion about respective axes substantially parallel to said principal axis of said elongated rigid body, (d) first and second trucks coupled to said elongated rigid body at respective locations displaced from each other along said principal axis, each of said trucks including an axle member extending laterally from said elongated rigid body on each side thereof, (e) a steering member for at least one of said trucks, said truck being mounted on said steering member and said steering member being pivotally connected to be rotatable about an axis perpendicular to said elongated rigid body and said steering member having a portion extending parallel to said principal axis of said elongated rigid body, and (f) means linking said respective first and second footrests to said extending portion of said steering member so that said rocking motion of said first and second footrests is coupled to said extending portion of said steering member to cause rotational motion of said steering member about said axis perpendicular to said elongated rigid body.
Claim 2
Dependent Claim
223 words
A ski-turn simulator comprising: (a) an elongated rigid body having two ends and a principal axis therebetween, (b) first and second cross members attached to said elongated rigid body and extending laterally therefrom on both sides, (c) first and second footrests carried by said first and second cross members and pivotally connected thereto for rocking motion about respective axes substantially parallel to said principal axis of said elongated rigid body, (d) first and second trucks coupled to said elongated rigid body at respective locations displaced from each other along said principal axis, each of said trucks including an axle member extending laterally from said elongated rigid body on each side thereof, (e) a steering member for at least one of said trucks, said truck being mounted on said steering member and said steering member being pivotally connected to be rotatable about an axis perpendicular to said elongated rigid body and said steering member having a portion extending parallel to said principal axis of said elongated rigid body, and (f) means linking said respective first and second footrests to said extending portion of said steering member so that said rocking motion of said first and second footrests is coupled to said extending portion of said steering member to cause rotational motion of said steering member about said axis perpendicular to said elongated rigid body.
Claim 3
Dependent Claim
58 words
A ski-turn simulator in accordance with claim 1 in which said elongated rigid body has a rigid ring that is coupled elastically to one of said first and second trucks so that rocking motion of said elongated rigid body about the principal axis causes rotational motion of said truck about said axis perpendicular to said elongated rigid body.
Claim 4
Dependent Claim
60 words
A ski-turn simulator in accordance to claim 2 in which the rotational motion of said truck about said axis perpendicular to said elongated rigid body is the total of that which is caused by said rocking motion of said first and second footrests and that which is caused by said rocking of said elongated rigid body about the principal axis.
Claim 5
Dependent Claim
255 words
A ski-turn simulator comprising: (a) an elongated rigid body having two ends and a principal axis therebetween, (b) first and second cross members attached to and extending laterally from said elongated rigid body on both sides thereof, (c) first and second footrests carried by said first and second cross members and pivotally connected thereto for rocking motion about respective axes substantially parallel to said principal axis of said elongated rigid body, (d) first and second trucks coupled to said elongated rigid body at respective locations displaced from each other along said principal axis, each of said trucks including an axle member extending laterally from said elongated rigid body on each side thereof, said coupling being effective to rotate said axle member about an axis perpendicular to said principal axis in response to rocking motion of said elongated rigid body about said principal axis, (e) a steering member for at least one of said trucks, said truck being mounted on said steering member and said steering member being pivotally connected to be rotatable about an axis perpendicular to said elongated rigid body and said steering member having a portion extending parallel to said principal axis of said elongated rigid body, and (f) means linking said respective first and second footrests to said extending portion of said steering member so that said rocking motion of said first and second footrests is coupled to said extending portion of said steering member to cause rotational motion of said steering member about said axis perpendicular to said elongated rigid body.
Claim 6
Dependent Claim
255 words
A ski-turn simulator comprising: (a) an elongated rigid body having two ends and a principal axis therebetween, (b) first and second cross members attached to and extending laterally from said elongated rigid body on both sides thereof, (c) first and second footrests carried by said first and second cross members and pivotally connected thereto for rocking motion about respective axes substantially parallel to said principal axis of said elongated rigid body, (d) first and second trucks coupled to said elongated rigid body at respective locations displaced from each other along said principal axis, each of said trucks including an axle member extending laterally from said elongated rigid body on each side thereof, said coupling being effective to rotate said axle member about an axis perpendicular to said principal axis in response to rocking motion of said elongated rigid body about said principal axis, (e) a steering member for at least one of said trucks, said truck being mounted on said steering member and said steering member being pivotally connected to be rotatable about an axis perpendicular to said elongated rigid body and said steering member having a portion extending parallel to said principal axis of said elongated rigid body, and (f) means linking said respective first and second footrests to said extending portion of said steering member so that said rocking motion of said first and second footrests is coupled to said extending portion of said steering member to cause rotational motion of said steering member about said axis perpendicular to said elongated rigid body.
Claim 7
Dependent Claim
23 words
A ski-turn simulator in accordance with claim 4 in which said axle member has a wheel journalled through bearings at each end thereof.
Claim 8
Dependent Claim
34 words
A ski-turn simulator in accordance with claim 4 in which each of said first and second tracks is coupled to said elongated rigid body through a rigid ring and at least one resilient ring.
Claim 9
Dependent Claim
23 words
A ski-turn simulator in accordance with claim 4 in which each of said linking means includes a coil for imparting appreciable compliance thereto.
