FOUR WHEEL DRIVE TOY

摘要

FOUR WHEEL DRIVE TOY A four wheel drive toy includes a drive means and two pairs of elongated movable track portions mounted on a frame, each pair of track portions including a follower gear driven through an independent gear train from the drive means. An interior surface of each track portion includes an oval endless rack gear engaged by the gear follower. The orbit of the gear follower around the rack gear is made visible from the exterior of the vehicle by using flanges attached to either side of the follower gear to retain the follower gear within the interior of the track portion. The track portion pivots about the axis of the follower gear when the follower gear reaches the arcuate region of the oval rack gear.
