A toy vehicle utilizes a depressible stunt wheel to elevate the vehicle to perform various tricks. An adjustable nob on the vehicle's chassis permits a user to preselect the distance the vehicle travels before the stunt wheel is automatically depressed. A shaft positionable in various slots in the vehicle's roof permits a user to preselect and fix the angle of the stunt wheel, during depression, relative to the traveling wheel of the vehicle, and the extent to which the stunt wheel is depressed below the chassis.

1. A toy vehicle, comprising: a chassis; a traveling wheel, rotatably mounted on said chassis, supporting said vehicle; a stunt wheel, supported by said chassis, depressible to contact a running surface and elevate said vehicle; and means, supported by said chassis, for selecting a distance from a predetermined range, and for continuously depressing said stunt wheel in contact with said running surface, elevating said vehicle, after said vehicle has traveled said distance. 2. A toy vehicle as in claim 1 further comprising means for preselecting, from a plurality of choices, an extent to which said stunt wheel is depressed relative to said chassis. 3. A toy vehicle as in claim 2 further comprising means for preselecting an angle of said stunt wheel, during depression, relative to said traveling wheel, and for fixing said stunt wheel at said angle. 4. A toy vehicle as in claim 3, wherein said selecting and depressing means comprises: means, supported by said chassis, for, upon activation, lowering said stunt wheel; and means, responsively coupled to said traveling wheel, for activating said lowering means after a rotation of said traveling wheel preselected from a predetermined range. 5. A toy vehicle as in claim 4 wherein said angle preselecting means comprises: a surface, supported by said chassis, having an opening therein comprising a plurality of slots; and a shaft, having a first end, and a second end pivotally coupled to said stunt wheel so that predetermined movement of said first end of said shaft engenders angular movement of said stunt wheel, said first end of said shaft projecting through said opening of said surface and positionable in said slots, said slots corresponding to predetermined angles of said stunt wheel. 6. A toy vehicle as in claim 5, wherein: depression of said stunt wheel engenders proportional extension of said shaft through said opening in said surface; and said means for preselecting an extent to which said stunt wheel is depressed relative to said chassis comprises a shoulder disposed between said first and second ends of said shaft, and at least one of said slots is configured to preclude passage of said shoulder therethrough upon extension of said shaft. 7. A toy vehicle as in claim 6, wherein said lowering means comprises: a carriage, pivotally mounted on said chassis, coupled to said stunt wheel, and having a notch therein; an arm, having a projection thereon aligned to engage said notch in said carriage, a first end pivotally mounted on said chassis, and a second end; and a spring, coupled between said carriage and said arm, urging said carriage downward and said arm against said carriage, engagement of said projection on said arm with said notch in said carriage preventing downward motion of said carriage urged by said spring, and urging of said arm against said carriage by said spring securing said engagement. 8. A toy vehicle as in claim 7, wherein said activating means comprises: a member, coupled to said traveling wheel, rotating in a first direction in response to rotation of said traveling wheel corresponding to forward motion of said vehicle, rotating in a direction opposite said first direction in response to rotation of said traveling wheel corresponding to backward motion of said vehicle, and having a projection thereon disposed so that upon rotation of said member in said first direction to a predetermined position said projection displaces said second end of said arm, disengaging said projection on said arm from said notch in said carriage, said member being rotatable independently of said traveling wheel only in said first direction, for selectively positioning said projection thereon. 9. A toy vehicle as in claim 1, further comprising means for preselecting an angle of said stunt wheel, during depression, relative to said traveling wheel, and for fixing said stunt wheel at said angle. 10. A toy vehicle as in claim 9, wherein said angle preselecting means comprises: a surface, supported by said chassis, having an opening therein comprising a plurality of slots; and a shaft, having a first end, and a second end pivotally coupled to said stunt wheel so that predetermined movement of said first end of said shaft engenders angular movement of said stunt wheel, said first end of said shaft projecting through said opening of said surface and positionable in said slots, said slots corresponding to predetermined angles of said stunt wheel. 11. A toy vehicle as in claim 10, wherein said selecting and depressing means comprises: means, supported by said chassis, for, upon activation, lowering said stunt wheel; and means, responsively coupled to said traveling wheel, for activating said lowering means after a rotation of said traveling wheel preselected from a predetermined range. 12. A toy vehicle as in claim 11, wherein said lowering means comprises: a carriage, pivotally mounted on said chassis, coupled to said stunt wheel, and having a notch therein; an arm, having a projection thereon aligned to engage said notch in said carriage, a first end pivotally mounted on said chassis, and a second end; and a spring, coupled between said carriage and said arm, urging said carriage downward and said arm against said carriage, engagement of said projection on said arm with said notch in said carriage preventing downward motion of said carriage urged by said spring, and urging of said arm against said carriage by said spring securing said engagement. 13. A toy vehicle as in claim 12, wherein said activating means comprises: a member, coupled to said traveling wheel, rotating in a first direction in response to rotation of said traveling wheel corresponding to forward motion of said vehicle, rotating in a direction opposite said first direction in response to rotation of said traveling wheel corresponding to backward motion of said vehicle, and having a projection thereon disposed so that upon rotation of said member in said first direction to a predetermined position said projection displaces said second end of said arm, disengaging said projection on said arm from said notch in said carriage, said member being rotatable independently of said traveling wheel only in said first direction, for selectively positioning said projection thereon. 14. A toy vehicle as in claim 1, wherein said selecting and depressing means comprises: means, supported by said chassis, for, upon activation, lowering said stunt wheel; and means, responsively coupled to said traveling wheel, for activating said lowering means after a rotation of said traveling wheel preselected from a predetermined range. 15. A toy vehicle as in claim 14, wherein said lowering means comprises: a carriage, pivotally mounted on said chassis, coupled to said stunt wheel, and having a notch therein; an arm, having a projection thereon aligned to engage said notch in said carriage, a first end pivotally mounted on said chassis, and a second end; and a spring, coupled between said carriage and said arm, urging said carriage downward and said arm against said carriage, engagement of said projection on said arm with said notch in said carriage preventing downward motion of said carriage urged by said spring, and urging of said arm against said carriage by said spring securing said engagement. 16. A toy vehicle as in claim 15, wherein said activating means comprises: a member, coupled to said traveling wheel, rotating in a first direction in response to rotation of said traveling wheel corresponding to forward motion of said vehicle, rotating in a direction opposite said first direction in response to rotation of said traveling wheel corresponding to backward motion of said vehicle, and having a projection thereon disposed so that upon rotation of said member in said first direction to a predetermined position said projection displaces said second end of said arm from said notch in said carriage, said member being rotatable independently of said traveling wheel only in said first direction, for selectively positioning said projection thereon.
