Abstract
An improved platformed vehicle having a steerable front wheel is disclosed. The vehicle includes a bifurcated platform with the tail of the platform being divided into first and second branches. Rear wheels are mounted, in pairs, on the underside of each of the branches of the platform. A pair of steerable front wheels are mounted below the platform near the front of the platform. The sprocket wheels are also attached to the underside of the front of the platform. The first sprocket wheel is coupled to the steerable front wheel, while the second sprocket wheel, mounted just behind the first sprocket wheel, is couple to a steering mechanism which passes through the platform. A chain drive couples the two sprocket wheels and thus couples the steering mechanism to the front wheels. The second sprocket wheel has a larger diameter than does the first sprocket wheels so that small turns of the steering mechanism are translated into relatively large changes in the front wheel direction. The steering mechanism is adaptable for play or industrial use. In an industrial application the platform may include a basket for carrying goods.
