The overall weight of the vehicle with respect to the combined mass and gyroscopic force which the gyroscopic wheels can produce for given rpm speeds is maintained within a predetermined operating range in order to provide the increased stunt maneuverability and stabilization during operation.

Abstract: A gyroscopic figurine (10) is disclosed having a body (11) and a gyroscope (12) mounted within the body. The gyroscope (12) has a rotatable wheel (15) coupled with the shaft (23) of an electric motor (16).

The body has a torso (26), a head (28), pivoting arms (29), a fixed leg (30), and a moveable leg (33). The relative positioning of the arms, legs and torso cause the figurine to become unbalanced and thus move while the gyroscope operates. The unbalancing of the gyroscopic wheel causes the figurine to vibrate and thus enhance the skating effect of the figurine upon an underlying surface.

Abstract: A toy vehicle having front opening gates and an ejectable flywheel seat which may be used as a gyroscopic top or to propel the vehicle. The flywheel seat is removably mounted to the top of the vehicle. A launching level rotatably coupled to the front axle of the vehicle may be used to simultaneously eject the flywheel seat from the toy vehicle and open two gates at the front of the vehicle. Downward movement of the level causes a tiltable box to rotate resulting in the seat being ejected from the vehicle. Movement of the lever also causes a sliding plate to move forward forcing the front gates to open. A flywheel is rotatably mounted inside the flywheel seat. When the flywheel seat is mounted on top of the vehicle, gears coupled to the front axle and mounted inside the tiltable box cause the flywheel to rotate inside the seat as the front wheels of the vehicle rotate. As such, the kinetic energy of the flywheel may be used to propel the toy vehicle forward.

Abstract: A miniature toy car for performing side-wheelie stunts. The toy car has a horizontally mounted flywheel with a vertical spin axis disposed near the bottom of the car. The center of gravity of the flywheel lies substantially in a horizontal plane passing through the rear axle of the car. The inertial motor uses a bevel pinion gear which is attached to the rear axle and engages a change gear. The change gear, in turn, engages a pinion gear attached to the flywheel. The orientation of the flywheel toward the bottom of the car helps to balance the car when it is performing side-wheelie stunts so that the spin axis of the flywheel approaches a horizontal position during such stunts. The sides of the wheels are made of a low friction material which allows the wheels to slide along a supporting surface and make directional changes during side-wheelie stunts as a restoring torque from the inertial motor keeps the car in a balanced position.

Abstract: A miniature toy vehicle capable of performing rear wheelies, spinouts and other playful stunts, the vehicle including a chassis having rotatable front and rear wheel axles mounted thereon, a hollow body being supported on the chassis to simulate the appearance of an automobile. A flywheel motor is supported for rotation on the chassis within the body on a flywheel axle normal to the rear wheel axle. The flywheel axle is operatively coupled to the rear wheel axle whereby when the rear wheel axle is rotated, it causes the flywheel motor to spin and to store energy for propelling the vehicle in the forward direction. The relationship of the flywheel motor to the structure of the vehicle is such as to cause the vehicle to behave as a gyro exhibiting precessional motion which in combination with the concurrent forward motion makes it possible for the vehicle to perform stunts.The flywheel has a layer of abrasive material on its upper face.
