Abstract: 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.

Abstract: 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.

Abstract: A vertical take off and landing aircraft toy has a fuselage with a plurality of fins and a rotor assembly. The rotor assembly may be driven by an electric motor, powered by a battery, an air motor powered by compressed air, or a gasoline engine, radio controlled in each case to control the speed of the motor. The rotor assembly includes a head portion coupled to the motor output shaft, a central hub coupled to the head portion, and a pair of airfoil blades. The head portion allows pivoting of the central hub about an axis generally aligned with the axis of the blades, while the blades are pivotable with respect to the central hub about an orthogonal axis. The fins on the fuselage resist counterrotation of the fuselage with respect to the rotation of the blades; alternatively, a pair of counterrotating blades may be provided.

Abstract: Toy racing vehicles for operating on preexisting track of a particular scale comprise sub bodies including conventional chassis and larger-scale “visible cars”, which are supported by the sub bodies, but are not fixed or mounted thereto. Instead, a visible car simply rests on the sub body, and is retained loosely thereon by one or more guide pins mounted on the sub body, and fitting loosely within apertures in a plate fixed with respect to the visible car. Accordingly, when the larger-scale visible cars bump one another during racing, they can be jostled out of their normal positions on their sub bodies, but are not separated therefrom, and return to their normal positions when the contact ceases. Realistic and exciting racing action results.

Abstract: A toy racing car or other vehicle for operating on conventional track of a given scale a comprises a sub body, including a chassis, motor and gear set, pickup shoes and drive wheels, and a visible body of much larger scale, with large scale rear drive wheels. In one embodiment, the body is pivoted to the sub body, so as to swing outwardly in turns, simulating a broadsliding race car; large scale front wheels are carried by the sub body, so as to simulate countersteering. A toy motorcycle similarly comprises a sub body and modeled motorcycle components; the front wheel and fork of the motorcycle remain upright in turns, while the rider and frame lean over, simulating a motorcycle leaning in a turn.

Abstract: 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.

Abstract: A vertically adjustable workstation comprises one or more legs having a vertical adjustment mechanism which provides an automatic self-braking function. The vertical adjustment mechanism comprises a highly efficient rotating member, such as a ball screw and ball nut assembly. Securely attached to the ball screw and the work surface is a clutch mechanism. The clutch mechanism has on one end a friction cap which is frictionally engaged with the work surface, and a thrust bearing which provides a first rotational interface between the ball screw and the clutch mechanism. The clutch mechanism comprises a roller clutch which allows for free rotation of the ball screw in the upward direction and is engaged with the ball screw when rotated in a downward direction. This arrangement comprises a load path which is directed from the work surface through the mating friction surfaces, the clutch mechanism and thrust bearing into the ball screw.

Abstract: An articulated support for a display including a base having a fore-to-aft slide assembly located proximate a rear portion of the base, a primary support for supporting the display, and having a pivot glide assembly depending from a rear portion of the primary support received within the fore-to-aft slide assembly for simultaneous translation and rotation therein, and a linkage assembly pivotally interconnecting the primary support to a forward portion of the base such that when the forward portion of the primary support is moved vertically, the primary support is simultaneously rotated and translated at a predetermined, synchronous rate with respect to the vertical translation of the forward portion of the primary support to automatically adjust the display as the user's viewing position changes vertically.
