The flying disc has at least one circular airfoil 11 and there are openings inside the area bound by its inner edge and the axle 3. Air currents from the direction of the flight that pass over and under the airfoil 11 are able to effectively mix through these openings. When slung with the string 4, the flying disc starts to rotate rapidly and flies away. It returns to the user when winding the string 4 back in the manner of a yo-yo.

  • Patent number: 6629873
    Abstract: A swinging bob toy having a middle bob with a non-cylindrically symmetric internal structure. The center of mass is located near the middle of the bore axis, and the percentage azimuthal variation V in the moment of inertia I about an axis in the equatorial plane, given by V=100×[I(&phgr;max)−I(&phgr;min)]/I(&phgr;max), is minimized, for instance by positioning the internal components to produce a weight distribution with n-fold symmetry, where n≧3. In one preferred embodiment, the bobs are equipped with lights powered by on-board batteries. Flat cylindrical batteries are mounted on an equatorial circuit board with their axes of symmetry perpendicular to the bore axis. To allow battery replacement, the top and bottom halves of each bob are removably attached by screw-secured posts parallel to, but offset from, the bore axis. An on/off switch is accessible via a small aperture through a transparent outer shell.

  • Patent number: 6607420
    Abstract: A gyroscopic toy is provided having a shaft to which is coupled a flywheel. A drive gear is used to spin the shaft and flywheel for spinning the toy. A pinion gear is rotated to impart spin energy to the shaft and flywheel and thus to the toy. A gearing mechanism couples the drive gear to the pinion gear when the pinion gear is rotated in a first direction and decouples from the drive gear when the pinion gear is rotated in a second opposite direction. A transmission may be provided allowing for at least two different gearing sets to be selectively coupled to the drive gear when the pinion gear is rotated in the first direction.
