Abstract

A power unit for a toy or a system of toys that can removable receive the power unit. The power unit comprises a drive gear that can provide rotational power to one or more driven components of a toy with which the power unit is associated. The drive gear can comprise multiple drive portions. The toys can comprise a wide variety of toy types.

Claims

1. A toy system, comprising:

a power unit comprising a body, a motor, a drive element driven by the motor, wherein the drive element comprises at least a first drive portion and at least a second drive portion positioned on a single drive shaft driven by the motor, the first drive portion spaced apart from the second drive portion;

wherein the power unit is insertable into a first toy body and a second toy body such that;

the drive element is configured to engage a first driven element of the first toy body and the power unit is configured to drive the first driven element, and

the drive element is configured to engage a second driven element of the second toy body that is different from the first toy body and the power unit is configured to drive the second driven element,

wherein the at least a first drive portion of the drive element is configured to be utilized during the engagement of the drive element with the first driven element and the second drive portion of the drive element is configured to be utilized during the engagement of the drive element with the second driven element.

2. The toy system of claim 1, wherein the drive element can drive different types of driven elements.

3. The toy system of claim 2, wherein the drive element comprises two or more of a spur gear portion, a worm gear portion and a drive coupling portion.

4. The toy system of claim 1, wherein the power unit further comprises a controller within the power unit body.

5. The toy system of claim 1, wherein the first toy body is one of a toy vehicle, a toy robot, and a toy spinning top, and wherein the second toy body is one of a toy vehicle, a toy robot, and a toy spinning top.

6. The toy system of claim 1, further comprising a flying vehicle comprising a propulsion arrangement driven by the power unit.

7. The toy system of claim 1, wherein the flying vehicle comprises a powertrain portion comprising the propulsion arrangement and a body portion, wherein the body portion comprises a foam material.

8. The toy system of claim 1, wherein the power unit further comprises a source of power within the power unit body.

9. The toy system of claim 1, wherein the toy system further comprises the first toy body and the second toy body.

10. A power unit for a toy body, comprising:

a power unit body;

a motor within the power unit body;

a drive gear that is rotationally driven by the motor, wherein the drive gear has at least two discrete drive portions spaced apart from each other and positioned on a single drive shaft driven by the motor that can drive different driven components, the at least two discrete drive portions comprising a first drive portion and a second drive portion; and

a drive coupling portion configured to connect to a toy body, and

an intermediate portion positioned between the first drive portion and the drive coupling portion, wherein the intermediate portion is at least partially supported by the power unit body.

11. The power unit of claim 10, wherein the drive gear further comprises a slot.

12. The power unit of claim 11, wherein one or more of the first drive portion or the second drive portion is positioned within the slot and is visible through at least one end of the slot.

13. The power unit of claim 10, wherein the first drive portion includes a worm gear portion.
