Abstract

A wheel assembly for use on a toy car includes a roller defining an axis of rotation, a wheel portion connected to the roller. The periphery of the wheel portion an at least partially sticky surface, which includes a blank portion without a tendency to stick.

Claims

1. A wheel assembly for use on a toy car, the wheel assembly comprising:

a roller defining an axis of rotation, and

a wheel portion in connection with the roller, wherein

the wheel portion has a periphery, and

the periphery of the wheel portion has a sticky portion that is covered by a sticky surface, and a blank portion without a tendency to stick.

2. The wheel assembly as claimed in claim 1, wherein the blank portion comprises a portion of the periphery of the wheel portion which is devoid of the sticky surface.

3. The wheel assembly as claimed in claim 1, wherein

the roller includes a shaft and two of the wheel portions, and

the wheel portions are located about the shaft and rotatable upon rotation of the roller.

4. The wheel assembly as claimed in claim 3, wherein the two wheel portions are located at opposite ends of the shaft.

5. The wheel assembly as claimed in claim 4, wherein the peripheries of each of the two wheel portions are partially covered by a sticky surface.

6. The wheel assembly as claimed in claim 4, wherein each of the peripheries of the two wheel portions each has a blank portion without a tendency to stick.

7. The wheel assembly as claimed in claim 6, wherein each of the blank portions comprises a portion of the periphery which is devoid of the sticky surface.

8. The wheel assembly as claimed in claim 7, wherein the blank portions of the peripheries of the wheel portions are arranged consecutively about the axis of rotation.

9. The wheel assembly as claimed in claim 8, wherein the blank portions of the two wheel portions angularly overlap about the axis of rotation.

10. The wheel assembly as claimed in claim 9, wherein the overlap is in a range from 0 degrees to 40 degrees, about the axis of rotation and along a circumferential length of the periphery of the wheel portion.

11. The wheel assembly as claimed in claim 4, including a bridge that extends between the two wheel portions and radially from the roller, wherein the two wheel portions are connected through the bridge.

12. The wheel assembly as claimed in claim 17, wherein the circumferential length of the overlap is substantially the same as a circumferential length of the bridge.

13. The wheel assembly as claimed in claim claim 1, wherein the sticky surface is an undulated sticky surface.

14. A toy including the wheel assembly as claimed in claim 1.

15. The toy as claimed in claim 14, wherein the toy includes a housing with a bottom side having an opening, the wheel assembly is movable between an operating position in which the wheel assembly extends beyond the housing through the opening, and a non-operating position in which the wheel assembly is stowed in the housing, behind the opening.

16. The toy as claimed in claim 15, wherein the wheel assembly is pivotally attached to the housing and is movable between the operating position and the non-operating position through pivotal action.

17. The wheel assembly as claimed in claim 10, including a bridge that extends between the two wheel portions and radially from the roller, wherein the two wheel portions are connected through the bridge.
