Modular radio control for use with multiple toy vehicles
First Claim
1. A toy vehicle set comprising:
- a first toy vehicle including a body having an open cavity formed therein where the cavity opening is in the upper surface of the vehicle body;
electrically operated control means mounted within the body for controlling the motion of the first vehicle in response to a control signal;
a first set of electrical contacts mounted within the cavity, and means for electrically connecting the first set of contacts to the control means;
a modular radio control unit including a body shaped to removably plug into the cavity to secure the control unit to the vehicle body without the need to disassemble the vehicle body, and having an antenna which projects from the control unit body, whereby the antenna extends above the upper surface of the vehicle body when the control unit is plugged into the cavity;
a control circuit mounted within the control unit, including a radio receiver coupled to the antenna and responsive to signals from a remotely controlled radio transmitter and a drive circuit responsive to the radio receiver to provide the control signal at an output terminal to operate the control means;
a second set of electrical contacts mounted to the control unit and positioned so that the second set of contacts is caused to mate with the first set of contacts when the control unit is plugged into the cavity;
means for electrically connecting the second set of contacts to the output terminal of the drive circuit;
means for removably mounting a power source within the control unit body; and
means within the control unit body for connecting the power source to provide power to the control circuit, whereby when the control unit is placed within the cavity the control signal from the drive circuit is provided to the control means through the first and second sets of contacts so that the motion of the first vehicle may be remotely controlled in response to signals from the radio transmitter.

Abstract
A modular radio control unit for use with multiple toy vehicles is disclosed. The control unit is in the shape of a vehicle passenger compartment and is designed to plug into a cavity formed in each vehicle. The control unit contains a control circuit including a radio receiver and a motor drive circuit to control two motors mounted in the vehicle and connected to control the motion of the vehicle. The control unit also contains batteries to provide power to the control circuit and to the motors. A set of contacts is provided in the control unit and in each vehicle so that when the control unit is plugged into a vehicle cavity, the output signals from the drive circuits are provided to the motors to effect remote control of the vehicle in response to commands from a transmitter.

8. A toy vehicle set comprising:
-
a first toy vehicle including a body having a cavity formed therein; electrically operated control means mounted within the body for controlling the motion of the first vehicle in response to a control signal; a first set of electrical contacts mounted within the cavity, and means for electrically connecting the first set of contacts to the control means; a modular radio control unit including a body shaped to removably fit within the cavity; a control circuit mounted within the control unit, including a radio receiver responsive to signals from a remotely controlled radio transmitter and a drive circuit responsive to the radio receiver to provide the control signal at an output terminal to operate the control means; a second set of electrical contacts mounted to the control unit and positioned so that the second set of contacts mates with the first set of contracts when the control unit is placed within the cavity; means for electrically connecting the second set of contacts to the output terminal of the drive circuit; means for removably mounting a power source within the control unit body; means within the control unit body for connecting the power source to provide power to the control circuit, whereby when the control unit is placed within the cavity the control signal from the drive circuit is provided to the control means through the first and second sets of contacts so that the motion of the first vehicle may be remotely controlled in response to signals from the radio transmitter, a second toy vehicle including a second body having a second cavity formed therein which is shaped to removably receive the radio control unit therein; second electrically operated control means mounted within the second body for controlling the motion of the second vehicle in response to the control signal; a third set of electrical contacts mounted within the second cavity and positioned to mate with the second set of contacts when the control unit is placed within the second cavity; means for connecting the third set of contacts to the second control means, whereby when the control unit is placed within the second cavity the control signal from the drive circuit is provided to the second control means through the second and third sets of contacts so that the motion of the second vehicle may be remotely controlled in response to signals from the radio transmitter, and a seat module shaped to removably fit within the first and second cavities and further shaped in the form of an unoccupied passenger compartment, whereby the seat module may be placed within either the first or second cavity to conceal that cavity and to simulate an unoccupied vehicle.
