Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
213 words
A toy including a vehicle resembling a high performance dragster vehicle in combination with a flat elongate track with an upper running surface and upstanding sidewalls, comprising: a toy vehicle having a body and wheel assemblies, said body resembling a dragster racing car, said wheel assemblies including at least one wheel at the front portion of said body and a pair of driven wheels supporting the rear portion of said body; motor means carried by said body, said means including a coupling arrangement operatively coupling torque developed by said means to said driven wheels, said motor means being capable of delivering an amount of torque to said driven wheels to cause said front wheel to rise above and lose contact with said running surface when the vehicle is supported thereon with said track and vehicle in generally horizontal position; and means for cooperating with said track to produce lateral stability of said vehicle affixed to said rear portion of said body for contacting said running surface only when said front wheel leaves said surface to limit the height to which said front wheel rises and tending to return said front wheel to said running surface, said stability means comprising a generally downwardly extending leg pivotally mounted at its upper end to said body.
Claim 2
Dependent Claim
213 words
A toy including a vehicle resembling a high performance dragster vehicle in combination with a flat elongate track with an upper running surface and upstanding sidewalls, comprising: a toy vehicle having a body and wheel assemblies, said body resembling a dragster racing car, said wheel assemblies including at least one wheel at the front portion of said body and a pair of driven wheels supporting the rear portion of said body; motor means carried by said body, said means including a coupling arrangement operatively coupling torque developed by said means to said driven wheels, said motor means being capable of delivering an amount of torque to said driven wheels to cause said front wheel to rise above and lose contact with said running surface when the vehicle is supported thereon with said track and vehicle in generally horizontal position; and means for cooperating with said track to produce lateral stability of said vehicle affixed to said rear portion of said body for contacting said running surface only when said front wheel leaves said surface to limit the height to which said front wheel rises and tending to return said front wheel to said running surface, said stability means comprising a generally downwardly extending leg pivotally mounted at its upper end to said body.
Claim 3
Dependent Claim
47 words
A toy according to claim 1, wherein said leg includes a horizontally extending portion disposed adjacent its lower end and having a length dimension transversally of the longitudinal dimension of said body approximately that of the width of said running surface of said track between said sidewalls.
Claim 4
Dependent Claim
38 words
A toy according to claim 1, wherein said lateral stability means includes means for restricting the pivotal movement of said leg relative to said body to limit the distance said front wheel may rise above said running surface.
Claim 5
Dependent Claim
17 words
A toy according to claim 1 wherein said motor means is disposed rearwardly of said driven wheels.
Claim 6
Dependent Claim
19 words
A toy according to claim 1, including a weight member Detachably mounted on said front portion of said body.
Claim 7
Dependent Claim
33 words
A toy according to claim 1, wherein said front wheel is relatively smaller than said driven wheels, said driven wheels each including a flat rubber ring disposed about its periphery simulating racing slicks.
