摘要： A three wheeled vehicle comprises a front subframe having a front wheel journaled thereto and a seat for a rider mounted thereon, and a rear subframe having a pair of rear wheels journaled thereto. The front subframe is journaled to the rear subframe at a kingpin axis, which defines a caster angle with respect to the vertical. The kingpin axis is spaced by a trail dimension from the rear axle axis. The caster angle and trail dimension, together with the wheelbase dimension between the front and rear axle axes and the track dimension across the rear wheels, are chosen cooperatively to define the desired handling characteristics of the vehicle.

摘要： A motorized toy vehicle or Wall Racer that is capable of operating on vertical and inverted horizontal surfaces such as walls and ceilings, while being manufacturable at reasonable cost and operable on batteries having sufficient lifetime as to be enjoyable. One or more battery-powered fans draw air from around all or defined portions of the periphery of the chassis of the Wall Racer through a carefully-shaped duct, so that the air in the portion of the duct immediately adjacent the surface flows at high velocity and low pressure; the relatively greater pressure of the surrounding air urges the vehicle against the surface, allowing it to operate on vertical surfaces, such as walls, or inverted on horizontal surfaces, such as ceilings.

摘要： A radio-controlled toy skateboard comprises a deck and front and rear trucks. The individual wheels of the rear truck can be controlled separately responsive to radio signals from a remote transmitter for rotation in either direction, while the front wheels rotate freely. Also responsive to radio control signals, the rear truck is controllably pivoted with respect to the deck about a kingpin axis that is inclined rearwardly, while the front truck pivots freely about a forwardly inclined kingpin axis. When the rear truck is thus pivoted, the deck tilts about its longitudinal centerline, causing the front truck to pivot correspondingly, steering the skateboard. A pair of modeled shoes are mounted for free pivoting about pivot axes. As the board tilts toward one side or the other, the shoes pivot from a toes-in to a toes-out position, mimicing the foot movements of a live “skater”. The forward shoe is mounted on a trolley sliding freely on an inclined ramp. When the board rests on a horizontal surface, the trolley slides forward, so that the forward shoe moves toward the forward end of the board; if the front end of the board is tilted upwardly, as in a “wheelie” manuever, the forward shoe slides rearwardly, as would that of a skater doing such a trick.
