First Claim
Patent Images
1. A toy vehicle track set, comprising:
- a track; and
a booster for accelerating toy vehicles over the track, the booster including;
a rotation source; and
a wheel operatively coupled to the rotation source, the wheel including a resiliently-folded member having an outer wall at an outer diameter of the wheel, an intermediate wall concentrically interior the outer wall, an outer linkage connecting the outer wall to the intermediate wall, and an inner linkage connecting the intermediate wall to the rotation source.

Abstract
A booster for accelerating toy vehicles. The booster includes a rotation source and first and second wheels operatively coupled to the rotation source. Each wheel includes a thin-walled member configured to engage toy vehicles passing between the wheels as the rotation source rotates the wheels in opposite directions. The thin walled member is characterized by an S-shape that allows the relative distance between the wheels to change, thereby accommodating differently sized vehicles.

13. A booster wheel assembly for accelerating toy vehicles, comprising:
-
a rotation source; a first wheel operatively coupled to the rotation source; and a second wheel operatively coupled to the rotation source; where the first wheel and the second wheel each include an S-shaped, thin-walled member configured to engage toy vehicles passing between the first and second wheels as the rotation source rotates the first and second wheels in opposite directions, and where the S-shaped, thin-walled member allows a relative distance between the first and second wheels to change to accommodate differently sized toy vehicles. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A thin-walled, booster wheel member for a toy vehicle booster wheel, the thin-walled member comprising:
-
an outer wall at an outer diameter of the booster wheel; an intermediate wall concentrically interior the outer wall; a substantially U-shaped outer linkage connecting the outer wall to the intermediate wall; and an inner linkage connecting the intermediate wall to an interior of the wheel such that the intermediate wall flexibly suspends the outer wall away from the interior of the wheel. - View Dependent Claims (21, 22, 23)
