Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
A vehicle comprising a vehicle body including at least one ground engaging wheel rotatably connected to said vehicle body, a main shaft mounted for rotation within said vehicle body, a flywheel rigidly connected to said main shaft, said flywheel including weight means capable of being shifted radially with respect to said main shaft, drive train means between said at least one ground engaging wheel and said main shaft for transmitting inertia to said flywheel in response to the rotative motion of the said at least one ground engaging wheel and means for shifting said weight means radially with respect to said main shaft to cause a variable inertia response in said vehicle through the interaction of said weight means and said flywheel.
Claim 2
Dependent Claim
122 words
A vehicle comprising a vehicle body including at least one ground engaging wheel rotatably connected to said vehicle body, a main shaft mounted for rotation within said vehicle body, a flywheel rigidly connected to said main shaft, said flywheel including weight means capable of being shifted radially with respect to said main shaft, drive train means between said at least one ground engaging wheel and said main shaft for transmitting inertia to said flywheel in response to the rotative motion of the said at least one ground engaging wheel and means for shifting said weight means radially with respect to said main shaft to cause a variable inertia response in said vehicle through the interaction of said weight means and said flywheel.
Claim 3
Dependent Claim
25 words
The vehicle of claim 1 wherein the flywheel is hollow and the weight means comprise at least one weighted shaft rotatably mounted within said flywheel.
Claim 4
Dependent Claim
26 words
The vehicle of claim 1 wherein the weight means comprise weighted gears rotatably mounted on said flywheel and located symmetrically with respect to said main shaft.
Claim 5
Dependent Claim
27 words
The vehicle of claim 1 wherein the means for shifting the said weight means comprises a gear train connected to said at least one ground engaging wheel.
Claim 6
Dependent Claim
12 words
In claim 1 wherein said vehicle is a flywheel propelled toy vehicle.
Claim 7
Dependent Claim
22 words
In the vehicle of claim 2, wherein said weighted shaft is at least two, mounted symmetrically with respect to said main shaft.
Claim 8
Dependent Claim
31 words
The vehicle of claim 2 wherein the means for rotating the said weight means comprises a gear train connected between the weighted shaft and the at least one ground engaging wheel.
Claim 9
Dependent Claim
39 words
The vehicle of claim 3 wherein the means for rotating the said weight means comprise a gear fixly mounted on said vehicle body whereby said weighted gears mesh with the fixed gear when the flywheel and main shaft rotate.
Claim 10
Dependent Claim
54 words
The vehicle of claim 7 wherein the gear train includes a weighted shaft gear attached to each weighted shaft, a central gear in engagement with each weighted shaft gear and rotatably supported on said main shaft whereby said main shaft and flywheel can rotate with respect to said central gear and weighted shaft assembly.
