ULTRACOMPACT SELF-POWERED MINIATURE TOY VEHICLE WITH FOUR-WHEEL DRIVE AND UNUSUAL CLIMBING CAPABILITY ABSTRACT OF THE DISCLOSURE A toy vehicle only slightly longer than a "pen- light" battery, and with chassis less than twice the width of such a battery, is able (traction permitting) to climb any grade on which it will not tip over back- ward -- grades up to about 40° -- and to negotiate a vertical step taller than its tire radius. The AA-battery-powered four-wheel-drive vehicle has a small electric motor with a double-ended shaft, and a symmet- rical gearing system consisting of, at each end of the motor, a pinion fixed on the shaft, a spur gear driven by the pinion and driving a worm, and a worm gear keyed to a corresponding axle. The motor, pinions, spur gears and worms, and the upper portions of the worm gears, are aligned along one side wall inside the vehicle chassis, with the battery alongside them occupying the rest of the chassis. Traction and climbing characteristics are enhanced by twice-overscale tires, preferably of open foam, with highly pronounced treads. A light distributor in the vehicle simulates two headlights, using light from a single small light bulb. - 1 -
