Abstract: A three-wheeled vehicle is disclosed having an improved simplified, light weight, tubular frame design which provides a U-shaped anti-sway bar for resistance to twisting of the frame and allows a steering system having a pair of front wheels to be steered by a handlebar that is mounted on a vehicle frame member beneath the seat of the vehicle operator, the handlebar curving upward and wider than the seat for convenient operation and access to the vehicle seat. The frame for the seat of the operator is provided by the anti-sway bar. The front wheels mount to the frame behind operator's feet, under normal riding conditions; steering being such that sharp turns may be made without interference between the wheels on the one hand and the frame and steering members on the other.

Abstract: Juvenile toy vehicle with a braking arrangement including front and rear axles supporting front and rear wheels, respectively, a pipe frame having the front and rear axles mounted in the front and the rear ends thereof, respectively, a sprocket wheel having a crank shaft provided with a pair of pedals and positioned on the pipe frame, another sprocket wheel rigidly mounted on the rear axle and linked with the crank shaft sprocket wheel by the intermediary of an endless chain, and a steering wheel linked with the front axles to permit change of a running direction of the vehicle.One of the rear wheels is rigidly disposed on the rear axle for integral rotation with the rear axle sprocket wheel, while the other rear wheel is journaled rotatably on the rear axle. The rear axle and the crank shaft are rotatably supported between an opposed pair of complimentary bush halves which are surrounded and held together by a fixture rigidly secured on the pipe frame.

Abstract: A pair of elongated, parallel tubes. A frame is formed by transverse members joining the tubes at each end thereof. Wheels are affixed to each end of the frame and are interconnected by tie rod structures such that the wheels operate together as a steering mechanism, each wheel turning in the opposite direction of the other wheel. A cover is attached over the frame, and, together with front and rear fender members attached to the frame adjacent the ends of the frame, forms a cavity. A motor is mounted within the cavity and drives a hydraulic pump. The pump drives hydraulic motors mounted in the hubs of the wheels.

Abstract: A three-wheeled motorcycle in which two front wheels are interconnected with a conventional motorcycle frame by a parallelogram configured coupling assembly utilizing a pair of cross members pivotally connecting hubs of the front wheels and pivotally connected to the frame. Foot resting platforms are positioned on either side of the motorcycle, being fixedly connected to one of the cross members in the front which is pivotally connected to the motorcycle frame.

Abstract: A four wheel, pedal driven vehicle particularly adapted for two persons seated in tandem, wherein each person alone or together can operate the vehicle by pedaling and steering. The vehicle comprises a unitary frame, a front spindle yoke assembly in combination with front handle bars and with front wheel forks of each front wheel, a steering control system in combination with the yoke assembly and rear handle bar means, a continuous drive chain assembly which is in combination with sprockets and pedals of both operator positions and which is in combination with transmission means and a rear drive assembly, whereby the drive chain can be driven from either tandem position. The vehicle has an associated body shell and cowls as well as conventional brakes, lights, etc.

Abstract: A manually propelled vehicle having a main frame supported on front and rear ground engageable wheels, a support body on the frame for supporting an occupant, control means operable by the occupant and comprising an oscillating drive member mounted to pivot about an axis transverse of the vehicle, a connecting rod interconnecting the drive member to a crank mechanism formed in a support axle for the rear wheels. A handle is pivotally connected to the drive member, with a pair of bowden cables interconnecting the handle with steering linkage systems cooperating with the axles of the front wheels. The bowden cables pass through the pivot axis of the drive member. The arrangement being such that oscillation of the drive member will cause the rear wheels to be driven by the connecting rod and crank mechanism, while pivoting movement of the handle due to downward pressure applied to one side or other of the handle will facilitate steering of the front wheels via the bowden cables and steering linkage systems.

Abstract: Conventional vehicles such as tricycles have two wheels at the back and a single wheel at the front. Alternatively, they may be constructed with two wheels at the front and one at the rear. In all cases, however, they are of a rigid construction and cannot "lean" on corners in a manner similar to a bicycle. Because of this, turning speed is limited and riding and manoeuvering awkward. The present device has a single rear wheel and a conventional frame and propulsion means. Two front wheels are mounted on an axle and the main frame on which the rider sits is journalled on a bearing secured to the axle so that the rider may lean into the turns. This arrangement also allows the frame and the rider to remain vertical when riding on a side slope and, in addition, provides a smoother ride than does a rigid vehicle.
