Abstract

Children'"'"'s ride-on vehicle assemblies having leading and trailing vehicles that are removably coupled together by a connection apparatus. The leading vehicle is an independently operable ride-on vehicle having a drive assembly that is selectively configured between a plurality of drive configurations, such as responsive to user inputs via user input devices. The assembly further includes a detection system adapted to detect whether or not the connection apparatus is in its coupled configuration and to restrict the plurality of drive configurations responsive thereto. This restriction may be automatic responsive to coupling of the leading and trailing vehicles together, and it may be made regardless of user inputs that otherwise would select and/or enable one of the restricted drive configurations.

Claims

1. A children'"'"'s ride-on vehicle adapted to be a leading vehicle of a children'"'"'s ride-on vehicle assembly having a leading vehicle and a trailing vehicle, the leading vehicle comprising:

a leading vehicle body having at least one seat adapted to receive a child;

a plurality of wheels rotatably coupled to the leading vehicle body and including at least one driven wheel and at least one steerable wheel;

a steering assembly including a steering mechanism adapted to receive steering inputs from a child sitting on the at least one seat and to convey the steering inputs to the at least one steerable wheel;

at least a portion of a connection apparatus adapted to selectively couple a trailing vehicle to the leading vehicle for relative movement with the leading vehicle, wherein the connection apparatus is in a coupled configuration when the trailing vehicle is coupled to the leading vehicle and in an uncoupled configuration when the trailing vehicle is not coupled to the leading vehicle; and

a drive assembly selectively configured to rotationally drive the at least one driven wheel of the leading vehicle in a plurality of drive configurations, the drive assembly comprising;

means for selectively driving the rotation of the at least one driven wheel;

at least one user input device adapted to selectively actuate the drive assembly; and

a sensor assembly adapted to detect when the connection apparatus is in the coupled configuration, wherein the drive assembly is adapted to restrict driving of the at least one driven wheel to a subset of the plurality of drive configurations when the sensor assembly detects that the connection apparatus is in the coupled configuration, and further wherein the plurality of drive configurations includes at least one drive configuration that is not in the subset of the plurality of drive configurations.

2. The ride-on vehicle of claim 1, wherein the at least one user input device includes at least one configuration input device adapted to receive user inputs selecting amongst the plurality of drive configurations.

3. The ride-on of vehicle of claim 2, wherein the drive assembly is adapted to restrict the plurality of drive configurations when the sensor assembly detects that the connection apparatus is in the coupled configuration regardless of user inputs selecting a drive configuration that is in the plurality of drive configurations but not in the subset of the plurality of drive configurations.

4. The ride-on vehicle of claim 1, wherein the drive assembly is adapted to be selectively configurable within the plurality of drive configurations when the connection apparatus is not in the coupled configuration.

5. The ride-on vehicle of claim 1, wherein the plurality of drive configurations and the subset of the plurality of drive configurations include at least one forward drive configuration in which the at least one driven wheel is driven in a forward direction.

6. The ride-on vehicle of claim 5, wherein the plurality of drive configurations further includes at least one reverse drive configuration in which the at least one driven wheel is driven in a reverse direction, and further wherein the subset of the plurality of drive configurations does not include a reverse drive configuration.

7. The ride-on vehicle of claim 5, wherein the plurality of drive configurations and the subset of the plurality of drive configurations include at least a first speed drive configuration, in which the motor assembly is adapted to drive the rotation of the at least one driven wheel at a first speed.

8. The ride-on vehicle of claim 7, wherein the plurality of drive configurations further includes a second speed drive configuration, in which the motor assembly is adapted to drive the rotation of the at least one driven wheel at a second speed that is greater than the first speed, and further wherein the subset of the plurality of drive configurations does not include the second speed drive configuration.

9. The ride-on vehicle of claim 7, wherein the plurality of drive configurations and the subset of the plurality of drive configurations further include a second speed drive configuration, in which the motor assembly is adapted to drive the rotation of the at least one driven wheel at a second speed that is greater than the first speed.

10. The ride-on vehicle of claim 1, wherein the plurality of drive configurations and the subset of the plurality of drive configurations include at least a first speed drive configuration, in which the motor assembly is adapted to drive the rotation of the at least one driven wheel at a first speed, wherein the plurality of drive configurations includes a second speed drive configuration, in which the motor assembly is adapted to drive the rotation of the at least one driven wheel at a second speed that is greater than the first speed, and further wherein the subset of the plurality of drive configurations does not include the second speed drive configuration.

11. The ride-on vehicle of claim 1, wherein the drive assembly further comprises a controller adapted to regulate at least one of the direction and the rate in which the at least one driven wheel is driven by the drive assembly.

12. The ride-on vehicle of claim 11, wherein the controller is adapted to communicate with the sensor assembly to restrict driving of the at least one driven wheel to the subset of the plurality of drive configurations when the connection apparatus is in the coupled configuration.

13. The ride-on vehicle of claim 1, wherein the sensor assembly includes a switch adapted to move between a first position, corresponding to the uncoupled configuration, and a second position, corresponding to the coupled configuration.

14. The ride-on vehicle of claim 13, wherein when the switch is in the first position, the drive assembly is adapted to selectively be configured to rotationally drive the at least one driven wheel in any of the plurality of drive configurations, and further wherein when the switch is in the second position, the drive assembly is adapted to restrict driving of the at least one driven wheel to the subset of the plurality of drive configurations.

15. The ride-on vehicle of claim 14, wherein the switch is adapted to be automatically moved to the second position responsive to the connection apparatus being configured from the uncoupled configuration to the coupled configuration.

16. The ride-on vehicle of claim 15, wherein the switch is adapted to automatically return to the first position when the connection apparatus is configured from the coupled configuration to the uncoupled configuration.

17. The ride-on vehicle of claim 13, wherein the switch is adapted to complete a circuit when moved to the second position.

18. The ride-on vehicle of claim 13, wherein the switch is adapted to open a circuit when moved to the second position.

19. The ride-on vehicle of claim 1, wherein the connection apparatus includes at least a portion of a hitch assembly adapted to selectively couple the trailing vehicle to the leading vehicle for relative movement with the leading vehicle.

20. The ride-on vehicle of claim 1, in combination with a trailing vehicle adapted to be removably coupled to the leading vehicle by the connection apparatus.
