Eccentric motion toy
View Patent ↗Various embodiments of the present invention are directed to a powered children's toy configured for movement along a support surface. According to various embodiments, the powered children's toy includes a drive system configured to impart a motive force on the children's toy that causes the toy to roll, bounce, shake, or otherwise move along an eccentric motion path when placed upon a support surface (e.g., a floor). Various embodiments of the drive system are configured to drive a rotating member about a movable rotation axis, thereby generating a varying motive force that causes eccentric movement along the support surface. This varying motive force assists in freeing the toy ball from obstacles encountered on a support surface (e.g., a wall or piece of furniture). In addition, the children's toy may include a power supply provided in a fixed position within the children's toy and configured for convenient user access.
1. A powered children's toy configured for movement along a support surface, the children's toy comprising:
a housing defining an interior area and configured for rolling along the support surface; and
a drive system positioned within the interior area and configured for driving a rotating member about a rotation axis, wherein the drive system is configured such that the position of the rotation axis with respect to the housing changes as the rotating member rotates about the rotation axis, thereby imparting a motive force to the children's toy.
2. The powered children's toy of claim 1 , wherein the motive force imparted by the drive system drives the children's toy in varying directions, thereby causing the children's toy to roll along an eccentric path on the support surface.
3. The powered children's toy of claim 1 , wherein the rotating member comprises a weighted member and the drive system comprises a motor configured for driving the weighted member about the rotation axis.
4. The powered children's toy of claim 3 , wherein the motor is operatively connected to a driveshaft defining the rotation axis.
5. The powered children's toy of claim 3 , wherein the drive system further comprises a platform supporting the motor and the weighted member within the interior area, the platform being movably connected to the housing such that, as the weighted member rotates about the rotation axis, the platform tilts with respect to the housing.
6. The powered children's toy of claim 5 , wherein the rotation axis is positioned in a fixed relationship with respect to the platform.
7. The powered children's toy of claim 5 , wherein the platform is resiliently connected to the housing.
8. The powered children's toy of claim 5 , wherein the platform is operatively connected to the housing by at least one ball joint.
9. The powered children's toy of claim 4 , wherein the weighted member is operatively connected to the driveshaft such that the weighted member's center of gravity is offset from the rotation axis.
10. The powered children's toy of claim 6 , wherein the rotation axis is oriented perpendicularly to the platform.
11. The powered children's toy of claim 7 , wherein the platform is operatively connected to housing by one or more springs.
12. The powered children's toy of claim 11 , wherein the platform is operatively connected to the housing by three or more springs and wherein rotation axis intersects the platform at a location in between the three or more springs.
13. The powered children's toy of claim 1 , wherein the rotating member comprises a motor configured to rotate about a driveshaft defining the rotation axis.
14. The powered children's toy of claim 13 , wherein the driveshaft is movably connected to the housing such that, as the motor rotates about the rotation axis, the driveshaft tilts with respect to the housing.
15. The powered children's toy of claim 13 , wherein at least one weight is attached to the motor.
16. The powered children's toy of claim 14 , wherein the driveshaft is resiliently connected to the housing.
17. The powered children's toy of claim 14 , wherein the driveshaft is operatively connected to the housing by at least one spring.
18. The powered children's toy of claim 17 , wherein the driveshaft is operatively connected to the housing by at least one ball joint.
19. The powered children's toy of claim 1 , wherein the housing's exterior surface defines a spherical shape.
20. The powered children's toy of claim 1 , wherein the housing's exterior surface further defines a plurality of projections.
21. The powered children's toy of claim 1 , wherein the drive system further comprises a power supply disposed within the interior area and secured in a fixed positioned with respect to the housing.
22. A powered children's toy configured for movement along a support surface, the children's toy comprising:
a housing defining an interior area and configured for rolling along the support surface;
a drive system positioned within the interior area and configured for driving a rotating member about a rotation axis, thereby imparting a motive force to the children's toy; and
a power supply configured for powering the drive system, the power supply being disposed within the interior area, secured in a fixed positioned with respect to the housing, and accessible through an opening in the housing.
23. The powered children's toy of claim 22 , further comprising a door panel disposed on the housing and configured for providing selective access to the power supply.
24. The powered children's toy of claim 22 , wherein the power supply comprises one or more removable batteries.
25. A powered children's toy configured for movement along a support surface, the children's toy comprising:
a housing defining an interior area and configured for movement relative to the support surface; and
a drive system positioned within the interior area and configured for driving a rotating member about a rotation axis, wherein the drive system is configured such that the position of the rotation axis with respect to the housing changes as the rotating member rotates about the rotation axis, thereby imparting a motive force to the children's toy.
