Abstract

A four wheel drive toy car having an elongated body with rounded ends and a diameter greater than the height of said elongated body so that the car will run equally well inverted. The wheels have convex outer sides so that the car will not rest on its side, and will cause the toy car to right itself when turned over, and rubber tires for good traction. A cord is connected to the electric motor driving the car and the car is steered by tugging on the electrical cord.

Claims

1. A car (10) having a body (11) and four wheels (12, 13, 14, 15),

a front axle (16) and a rear axle (17) supporting said wheels on said body,

a motor (18) on said body,

a first gear (19) on said front axle and the second gear (20) on said rear axle,

a sprocket (21) on said motor (18),

a first idler gear (22) connected between said sprocket (21) and said first gear (19),

a second idler (23) connected between said second gear (20) and said sprocket (21) whereby said wheels are driven in a first direction when said motor drives in a first direction and said wheels are driven in a second direction when said motor drives in a second direction.

2. The car recited in claim 1 wherein said body has a front end curved about the center of said axle and a rear end curved about the center perimeter of said rear axle and the wheels have a greater radius than the radius of said ends.

3. The car recited in claim 2 wherein each said wheel has a peripheral groove and a tire is supported in said peripheral groove of each said wheel.

4. The car recited in claim 3 wherin the outside surface of said wheels are convex whereby said car will not rest on its side but will tend to land on its tires.

5. The car recited in claim 1 wherein a battery pack is provided adapted to be hand-held by an operator.

a flexible electrical wire connecting said battery pack to said car,

said car being adapted to be steered by said electrical wire.

6. The car recited in claim 1 wherein an elongated semi-stiff member is attached to the rear end of said body and extends rearwardly therefrom,

means on the distal end of said member engaging said electrical cord for facilitating steering said car.

7. A car having a body,

a motor on said body,

front wheels and rear wheels attached to said body and supported thereon,

said body having a top surface, a bottom surface, front and rear end surfaces, and side surfaces,

said front and rear wheels extend above said top surface and below said bottom surface,

said front wheels extend beyond said front end surface, and said rear wheels extend beyond said rear end surface, whereby said wheels will engage a supporting surface and carry said car in an upright or inverted position and said wheels will engage and climb obstacles encountered in forward or rearward motion of said vehicle.

8. The car recited in claim 7 wherein said front and rear wheels have a convex outer surface whereby said car when tipped on its side will tend to roll onto the wheels in either an upright or inverted position.

9. The car recited in claim 8 wherein an elongated, relatively rigid member is attached to the rear end of said body and extends rearwardly therefrom,

means on the distal end of said relatively rigid member to engage an electric cord attached to said motor whereby said cord may be tugged to steer said car.

10. A car having a body,

a motor on said body, mounted centrally thereon,

front wheels and rear wheels attached to said body,

said body having a top surface, a bottom surface, front and rear end surfaces and side surfaces,

an elongated relatively rigid resilient member attached to the rear end of said body and extending rearwardly therefrom,

an electric cord attached to the body and connected to said motor means on the distal end of said relatively rigid member engaging said electric cord,

said cord being adapted to be manually pulled by an operator to steer said car.

11. The car recited in claim 10 wherein said front wheels and said rear wheels have convex outer surfaces whereby said car when tipped on its side will tend to roll onto the wheels in either an upright or inverted position.

12. The car recited in claim 11 wherein a front axle and a rear axle support said wheels on said body,

a first gear on said front axle,

a second gear on said rear axle,

a sprocket on said motor,

a first idle gear connected between said sprocket and said first gear,

a second idle gear connected between said second gear and said sprocket,

whereby said wheels are dirven in a first direction when said motor drive is in the first direction and said wheels are driven in a said second direction when said motor drives in said second direction.
