Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
118 words
A toy vehicle comprising: means defining a vehicle body having a top, bottom, opposite sides and opposite ends; a pair of generally spherical driving wheels rotatably connected to each end of the body for supporting the body relative to a supporting surface, each of said wheels having an outer perimeter which projects beyond the top and bottom and opposite sides of the body; and power means connected with the vehicle and in driving engagement with at least one of said wheels to rotate the same and propel the vehicle along a supporting surface whereby at least some portion of said wheels will be in engagement with a supporting surface, or surfaces transverse thereto, to continually drive said vehicle.
Claim 2
Dependent Claim
118 words
A toy vehicle comprising: means defining a vehicle body having a top, bottom, opposite sides and opposite ends; a pair of generally spherical driving wheels rotatably connected to each end of the body for supporting the body relative to a supporting surface, each of said wheels having an outer perimeter which projects beyond the top and bottom and opposite sides of the body; and power means connected with the vehicle and in driving engagement with at least one of said wheels to rotate the same and propel the vehicle along a supporting surface whereby at least some portion of said wheels will be in engagement with a supporting surface, or surfaces transverse thereto, to continually drive said vehicle.
Claim 3
Dependent Claim

The toy vehicle of claim 1 wherein said wheels are formed in closely spaced apart segments joined together by an axle and said body has extensions extending into the space between said segments for rotatably supporting said axle.
Claim 8
Dependent Claim
52 words
The toy vehicle of claim 1 wherein said power meaNs includes a motor and a source of power for the motor on the vehicle, both said motor and source of power being substantially located below the axis of rotation of the wheels to provide a low center of gravity to the vehicle.
Claim 9
Dependent Claim
35 words
The toy vehicle of claim 1 wherein two wheels are provided at opposite ends of the body, with driving gears on the body in engagement with each of the peripheral gear surfaces on each wheel.
