Toy vehicle
First Claim
1. A toy vehicle comprisingA. a frame having a front, a rear and a pair of opposite sides;
- B. at least three substantially equal diameter wheels rotatively mounted to each side of the frame at locations distributed between the front and rear of the frame so that the bottoms of all of the wheels lie in substantially the same plane;
C. first drive means mounted to the frame, said first drive means including(1) a relatively small DC electric motor;
(2) a speed reduction unit having an input gear driven by the motor and an output gear rotatively coupled to a first wheel at the front or rear of the frame;
D. second drive means mounted to the frame, said second drive means including(1) a second relatively small DC electric motor;
(2) a second drive unit having an input gear driven by the second motor and an output gear rotatively coupled to a second wheel at the front or rear of the frame and being located on the opposite side of the frame from said first wheel;
E. first means for rotatively coupling said first wheel and the wheel at the opposite end of the frame on the same side thereof;
F. second means for rotatively coupling said second wheel and the wheel at the opposite end of the frame on the same side thereof; and
G. wherein a wheel located between the coupled-together wheels on each side of the frame is an idler wheel;
H. a vehicle body mounted on the frame;
I. battery means supported by the frame;
J. means for electrically connecting the battery means to the motors, said connecting means including hand-operated control means having a plurality of operative positions for applying battery means voltage of either polarity to each drive motor whereby an occupant of the vehicle can drive the vehicle forward or in reverse or cause it to revolve in either direction without the vehicle'"'"'s slipping or stalling.

Abstract
A child'"'"'s battery-operated ride-on toy vehicle includes a frame having at least three equal diameter wheels rotatively mounted to the frame at opposite sides thereof. The wheels at the front and/or rear of the vehicle at opposite sides of the vehicle are driven by a pair of independently operated relatively small DC electric motors. The wheels at the middle of the vehicle are not driven, but idle. The vehicle includes an onboard battery which is connected to the motors by way of a joystick control so that the vehicle occupant, by manipulating the joystick, can apply a battery voltage of either polarity to the motors so that the vehicle moves forward or in reverse or revolves in either direction on the spot. Due to the presence of the idler wheels, the vehicle can maneuver on all types of surfaces including rugs and carpeting without slipping or stalling.

6. A child'"'"'s ride-on vehicle comprising
A. a generally rectangular tubular frame including (1) a pair of laterally spaced, fore- and aft-extending members; - and
(2) a pair of lateral members connected to the fore and aft members at spaced-apart locations therealong; B. axles journaled at the opposite ends of the two lateral members; C. similar relatively large diameter drive wheels connected to the axles; D. sprockets mounted to rotate with said axles; E. a chain loop connecting the two sprockets at each side of the frame; F. first electromechanical drive means supported by the frame for rotating a first axle at one side of the frame; G. second electromechanical drive means supported by the frame for rotating a second axle at the other side of the frame independently of the first axle; H. a vehicle body mounted to said frame; I. battery means supported by the frame; J. means for electrically connecting the battery means to the motors, said connecting means including hand-operated control means having a plurality of operative positions for applying battery means voltage of either polarity to each drive motor; and K. an idler wheel rotatively mounted to the frame between the drive wheels at each side of the frame, said idler wheel having substantially the same diameter as the drive wheels whereby an occupant can drive the vehicle forward or in reverse or cause it to revolve in either direction without the vehicle'"'"'s slipping or stalling. - View Dependent Claims (7, 8)
