ABSTRACT:
FIELD OF THE INVENTION
This invention relates to human-powered ride-on vehicles, and specifically to a ride-on vehicle having an oscillating rear driving wheel.
BACKGROUND OF THE INVENTION
There are many forms of human-powered vehicles described in the patent and technical literature. Some of these known vehicles are intended to provide a carnival-type ride, wherein the rider may, at the rider's will, be subjected to G-forces, generally of the lateral variety. Ride-on vehicles such as the Big Wheel® achieve such G-forces through the provision of a large, driven front wheel, and the provision of independent braking systems on much smaller rear wheels.
A variety of power systems are known for human powered, ride-on vehicles. U.S. Pat. No. 375,755, to Kidder, granted Jan. 3, 1888, for Velocipede depicts a tricycle having large, powered rear wheels and a small, steerable front wheel, mounted on a curved, non-forked support.
U.S. Pat. No. 1,620,926, to Trullinger, granted Mar. 15, 1927, for Coaster Wagon depicts a steering mechanism which incorporates a pivotable steering linkage.
U.S. Pat. No. 4,861,055, granted Aug. 29, 1989 for Drive Mechanism; U.S. Pat. No. 4,925,200, granted May 15, 1990 for Tricycle Drive Mechanism; and U.S. Pat. No. 5,829,772, granted Nov. 3, 1998 for Ride-on, Human-powered Vehicle Drive and Steering Mechanism are my previously issued patents depicting a variety of propulsion, steering and braking mechanism.
Ride-on vehicles for toddlers, however, are generally limited to the Kidde-Kar-type of vehicle, which is driven and turned solely by leg power of the rider. Such vehicles generally do not have any type of mechanical motive power because of the limited motor skills of the rider.
SUMMARY OF THE INVENTION
A ride-on vehicle having a longitudinal axis includes a body; a rear axle having a crank portion therein and rotatably secured to the body; a pair of spaced-apart driven rear wheels eccentrically fixed to the rear axle; a forward crank rotatably secured to the body and driven by a vehicle rider, and a shaft extending between the rear axle crank portion and the forward crank; wherein rotation of the forward crank results in a driving force being transmitted through the shaft to the rear axle crank portion, thereby causing the vehicle to move along its longitudinal axis and wherein the body oscillates vertically when the vehicle moves along its longitudinal axis.
An object of the invention is to provide a ride-on vehicle having an oscillating drive.
Another object of the invention is to provide a toddler ride-on vehicle having a whimsical body style and drive mechanism.
These and other objects and advantages of the invention will become more fully apparent as the description which follows is read in conjunction with the drawing.
