Abstract

A miniature electric toy vehicle having a chassis of approximately the same upper and lower configuration is provided for removably receiving a vehicle body. A miniature rechargeable battery can be connected to an operator controlled source of power for periodic recharging of the battery. The toy vehicle approximates the size of the battery and motor and can operate with a minimal recharge time period to enhance the play value for a child.

Claims

1. An electric toy vehicle with a rechargeable battery comprising:

a chassis member extending along a longitudinal axis and having an upper and lower portion of approximately the same exterior configurations and having a fore end and rear end positioned at opposite ends of the longitudinal axis;

a front and rear wheel assembly including wheels mounted on the chassis, each wheel being dimensioned with a diameter that is greater than the maximum distance between the upper and lower portions of the chassis member;

a rechargeable battery mounted within the chassis;

an electric motor mounted within the chassis and electrically connected to the battery;

means for recharging the battery from a source of power; and

at least one removable vehicle body, one of the chassis member and vehicle body having a set of male type connectors and the other having a set of female type receptacles for snap mounting of the vehicle body on the chassis member in a position that interfaces either the upper or lower portion of the chassis member.

2. The invention of claim 1 wherein the means for recharging the battery includes a manual switch mounted on the chassis and a connector, the battery terminals aligned parallel with the longitudinal axis, the overall length of the chassis approximately the width of the motor, connector and switch plus the length of the battery.

3. The invention of claim 2 wherein the electrical characteristics and weight of the vehicle permits a recharge time of approximately 1 second with a subsequent vehicle operation of greater than 10 seconds.

4. The invention of claim 3 wherein the rechargeable battery can provide 14 to 16 hours at 5 mA and the second primary battery source is a pair of 1.5 volts DC size C batteries.

5. The invention of claim 1 further including a separate hand-held body member having a power line, a second primary battery and a connector for providing power to the means for recharging, the body member further having a spring-biased button for control by an operator to electrically connect the second battery to the power line.

6. A miniature electric toy vehicle set with a rechargeable battery comprising:

a chassis member having an upper and lower portion, the chassis member being further configured and dimensioned to engage a body member which may thereby interface either the upper or lower portion;

a front and rear wheel assembly including wheels mounted on the chassis;

a first rechargeable battery mounted within the chassis and having a characteristic of providing 5 mA of current for a time period of approximately 14 hours;

an electric motor mounted within the chassis and electrically connected to the battery for propelling the toy vehicle at approximately 15 miles/hour;

a manual switch mounted on the chassis for operation by an operator to enable the vehicle to be recharged;

a first connector mounted on the chassis and electrically connected to the rechargeable battery; and

means for recharging the battery from a source of power, including a separate hand-held body member supporting a second battery source having a pair of 1.5 volt DC size C batteries, a power line, a second connector plug mounted on the chassis, the body member further having a control button for control by an operator to electrically connect the second battery source to the power line.

7. The invention of claim 6 wherein the electrical characteristics and weight of the vehicle permits a recharge time of approximately 1 second with a subsequent vehicle operation of greater than 10 seconds.

8. The invention of claim 7 wherein the chassis member has an upper and lower portion of approximately the same exterior configuration.

9. The invention of claim 8 wherein the vertical thickness of the chassis member is less than the diameter of the wheels.

10. A small electric toy vehicle with a rechargeable battery comprising:

a chassis having a longitudinal axis and an upper and lower portion;

a front and rear wheel assembly including wheels mounted on the chassis, the diameter of the wheels being greater than the vertical thickness measured between the upper and lower portions of the chassis;

a first rechargeable battery mounted within the chassis and having terminals aligned parallel with the longitudinal axis;

an electric motor mounted within the chassis and electrically connected to the first battery;

means for recharging the first battery from a source of power, including a manual switch mounted on the chassis and a first connector;

a removable vehicle body, one of the chassis and vehicle body having a set of male type connectors and the other having a set of female type receptacles for snap mounting of the vehicle body on the chassis;

a separate hand-held body member having a power line;

a second primary battery source mounted in the body member; and

a second connector attached to the second primary battery source for providing power to the means for recharging, the hand-held body member further having a control button for control by an operator to electrically connect the second battery to the power line and the length of the chassis being approximately equal to the width of the motor, first connector, manual switch, and length of the first battery.

11. The invention of claim 10 wherein the upper and lower chassis portions have approximately the same exterior configurations.

12. The invention of claim 10 wherein the first connector is mounted on the lower portion of the chassis adjacent a wheel assembly and the manual switch is positioned adjacent the first connector whereby the operator inverts the vehicle to recharge the battery within the chassis.
