Abstract: The golfrisbee emulates the human throwing process to launch the disk to fly. The golfrisbeer swivels the club to launch the golfrisbee to fly. The golfrisbee is launched to fly with the waist force to swivel the club at very high speed. With the high-speed swiveling club, the golfrisbee flies much farther and higher than the hand-throwing flying disk does. The complicated throwing process of human brain and hand cooperation mechanism is emulated with the simple screw mechanism. With the screw mechanism, we make the technology breakthrough in the swivel-to-launch technology. As the golfrisbeer swivels the club, the golfrisbee disk automatically rotates due to the eccentric force. As the club reaches the designated launching point, the golfrisbee automatically takes off and launches to fly in the sky. With the integrated multimedia device, the rainbow-like shining light and whistling harmonic sound make the golfrisbee much more fun to play with.

Abstract: A flying toy in the form of an aerodynamic flying ring. An annular disk (17) surrounds a central opening (12) to create a ring. A convex upper surface (11) deflects air flowing over the top side of the disk, increasing air speed and reducing downward air pressure. An aerodynamic protruding annular fin (27) located near the inner perimeter (18) of the unit deflects air upward again, increasing air speed and decreasing air pressure again. The lower side of the unit contains an undercut that can be straight (16), curved (20), or angled (22). This undercut creates a lower cutaway surface (19) which may be parallel to, or at an angle to, the horizontal plane. This structure captures air beneath the unit, slowing air speed and increasing upward air pressure on the unit. These features combine to provide greater lift capacity than any of them would produce separately. In the preferred embodiment the disk is made of a soft foam material such as polyethylene or polyurethane, but other materials could be used.

Abstract: A gliding or flying hydrodynamic disc designed for recreational use under water. The disc is circular and about 12 inches or 300 mm in diameter, and about ½ inch or 1.198 centimeters high.

The top and bottom of the device are symmetrical to minimize drag-inducing lift effects. A soft outer edge surface provides a good grip on the device and for safety in pool and dive use. The disc can also be used as a dive plane or to change course by holding it out in front while the user is swimming.
