Abstract

A toy vehicle includes a chassis having front and rear portions with a wheel supporting the front portion of the chassis. The toy vehicle further includes spaced-apart swing arms connected to the rear portion of the chassis. Rear wheels are rotatably mounted to each end of the swing arms. The swing arms are independently movable with respect to the chassis between first and second positions. Two separate propulsion drives are operatively associated with the chassis and are drivingly coupled to respective rear wheels. Each propulsion drive is adapted to independently drive the respective rear wheels in either a first direction or a second opposite direction.

Claims

1. A toy vehicle comprising:

a chassis having front and rear portions;

at least one wheel supporting said front portion of said chassis;

first and second spaced-apart swing arms having first and second ends, said first end being connected to said rear portion of said chassis, each of said second ends having a rear wheel rotatably mounted thereto, each of said swing arms being independently movable with respect to said chassis between first and second positions, whereby said rear wheels move closer to said front portion when said swing arms are moved from said first position to said second position; and

first and second propulsion drives operatively associated with said chassis and drivingly coupled to respective rear wheels, each propulsion drive adapted to independently drive a respective rear wheel in either a first direction or a second opposite direction.

2. The toy vehicle of claim 1, further comprising an anti-tipping structure affixed to at least one of said swing arms to prevent the toy vehicle from tipping backwards when both swing arms are in said second position.

3. The toy vehicle of claim 1, further comprising an anti-tipping structure affixed to said rear portion of said chassis to prevent the toy vehicle from tipping backwards when both swing arms are in said second position.

4. The toy vehicle of claim 1, further comprising a remote control receiver adapted to receive remotely generated control signals, said receiver operatively connected to each of said propulsion drives whereby said receiver may independently control each of said propulsion drives.

5. The toy vehicle of claim 1, further comprising a bias member extending between one of said swing arms and said chassis.

6. The toy vehicle of claim 1, wherein the toy vehicle operates on a support surface in an upright position and further comprises a self-righting member extending from said chassis, said self-righting member being configured to enable at least one of said rear wheels to contact the support surface when the toy vehicle is in a non-upright position.

7. The toy vehicle of claim 1, wherein said chassis has a longitudinal axis, said swing arms being substantially parallel to said longitudinal axis when in said first position and substantially perpendicular to said longitudinal axis when in said second position.

8. The toy vehicle of claim 1, further comprising a wheeled steering mechanism supporting said front portion of said chassis.

9. The toy vehicle of claim 8, wherein said wheeled steering mechanism comprises:

an elongated member having a slot extending therethrough, said elongated member being pivotally connected to said front portion of said chassis;

an axle extending through said slot, said axle having wheels disposed on opposite end of said axle, said axle being slidably movable within said slot.

10. A toy vehicle comprising:

a chassis having front and rear portions;

a wheeled steering mechanism supporting said front portion of said chassis;

first and second spaced-apart swing arms having first and second ends, said first end being connected to said rear portion of said chassis, each of said second ends having a rear wheel rotatably mounted thereto, each of said swing arms being independently movable with respect to said chassis; and

first and second propulsion drives operatively associated with said chassis and drivingly coupled to respective rear wheels, each propulsion drive adapted to independently drive a respective rear wheel in either a first direction or a second opposite direction.

11. The toy vehicle of claim 10, wherein said wheeled steering mechanism comprises:

an elongated member having a slot extending therethrough, said elongated member being pivotally connected to the front portion of said chassis;

an axle extending through said slot, said axle having wheels disposed on opposite end of said axle, said axle being slidably movable within said slot.

12. The toy vehicle of claim 10, further comprising a remote control receiver adapted to receive remotely generated control signals, said receiver operatively connected to each of said propulsion drives whereby said receiver may independently control each of said propulsion drives.

13. The toy vehicle of claim 10, wherein the toy vehicle operates on a support surface in an upright position and further comprising a self-righting member extending from said chassis, said self-righting member being configured to enable at least one of said rear wheels to contact the support surface when the toy vehicle is in a non-upright position.

14. A toy vehicle comprising:

a chassis having front and rear portions;

a wheeled steering mechanism supporting said front portion of said chassis, said wheeled steering mechanism comprising;

an elongated member having a slot extending therethrough, said elongated member being pivotally connected to the front portion of said chassis; and

an axle extending through said slot, said axle having wheels disposed on opposite end of said axle, said axle being slidably movable within said slot;

first and second rear wheels rotatably mounted to said rear portion of said chassis; and

first and second propulsion drives operatively associated with said chassis and drivingly coupled to respective rear wheels, each propulsion drive adapted to independently drive a respective rear wheel in either a first direction or a second opposite direction.

15. The toy vehicle of claim 14, wherein said axle slides to a rearward position in said slot when both of said rear wheels are operated in a first direction so as to provide a castering effect for said steering mechanism, said axle slides to a forward position in said slot when both of said rear wheels are operated in a first direction so as to provide a castering effect for said steering mechanism.

16. A remotely controlled toy vehicle comprising:

a chassis having front and rear portions;

a wheeled steering mechanism supporting said front portion of said chassis, said wheeled steering mechanism comprising;

an elongated member having a slot extending therethrough, said elongated member being pivotally connected to the front portion of said chassis; and

an axle extending through said slot, said axle having wheels disposed on opposite end of said axle, said axle being slidably movable within said slot;

first and second spaced-apart swing arms having first and second ends, said first end being connected to said rear portion of said chassis, each of said second ends having a rear wheel rotatably mounted thereto, each of said swing arms being independently movable with respect to said chassis between first and second positions, whereby said rear wheels move closer to said front portion when said swing arms are moved from said first position to said second position;

first and second propulsion drives operatively associated with said chassis and drivingly coupled to respective rear wheels, each propulsion drive adapted to independently drive a respective rear wheel in either a first direction or a second opposite direction; and

a remote control receiver adapted to receive remotely generated control signals, said receiver operatively connected to each of said propulsion drives whereby said receiver may independently control each of said propulsion drives.
