DESCRIPTION OF THE INVENTION

[0020] This invention could easily apply the flying saucer though a core of bowling ball with a rotating disk that transforms the vertical force into horizontal force.

[0021] Please refer to FIG. 1A. FIG. 1A shows an exploded view of the core of bowling ball of the instant application. The core of bowling ball 100 is covered on a ball 10. The core of bowling ball 100 includes a rotating disk 130, a center bearing 120, a finger hole bar 110 and a plurality of joint pole 140. The center bearing 120 is disposed on the center of the rotating disk 130. The finger hole bar 110 is linked to the center bearing 120. The joint poles 140 are passed through the center bearing 120 and contacted with a bottom bearing 150 of bottom of the ball 10. In other word, the rotating disk 130 is linked to the outside of the center bearing 120. The finger hole bar 110 is embedded into the inside of the center bearing 120. Thus, the rotating disk 130 and finger hole bar 110 can rotate respectively and freely. In this embodiment, the finger hole bar 110 and center bearing 120 are disposed on the center axis of the ball 10. The one end of the finger hole bar 110 is flushed with surface of ball 10. The finger hole bar 110 further includes a finger hole 11. The finger hole 11 is disposed in the surface of ball 10. Further explanation, the location of the finger hole 11 must be disposed on the center axis of the ball 10.

[0022] The joint pole 140 are passed through the rotating disk 130 and disposed on the radial direction of the rotating disk 130. The long side of the joint pole 140 is vertical with the radial direction of the rotating disk 130. Please refer to FIG. 1B. FIG. 1B shows a schematic diagram of the rotating disk. The rotating disk 130 further includes a plurality of gasket 132 and joint pole bearing 131. The joint pole bearing 131 are disposed between the joint pole 140 and the rotating disk 130. The joint pole bearing 131 is disposed on the location where the joint pole 140 penetrates the rotating disk 130. The gasket 132 disposed between the rotating disk 130 and ball 10, and the joint pole 140 is passed through the gasket 132.

[0023] Please refer to FIG. 1C. FIG. 1C shows side view of the core of the bowling ball. The length of the joint pole 140 is enough to link to the ball 10. Thus, when the rotating disk 130 rotates, the rotating disk 130 can make the ball 10 to rotate via the joint pole 140. The joint pole 140 is disposed vertically with rotating disk 130. Therefore, when the rotating disk 130 drives the ball 10, the torque of the ball 10 can be promoted. In addition, all components of the ball 10 and the core of ball 10 are non-metallic materials to compliant with international bowling regulations. In some embodiment, components of the ball 10 and the core of bowling ball 100 are made by Polyurethane or Ultra High Molecular Weight Polyethylene (UPE). It also can be made by materials mixed by cork and reinforced rubber, and the outside is covered by hard rubber, plastic or glass fiber.

[0024] In addition, in some embodiment, the core of bowling ball 100 further includes a bottom bearing 150. The bottom bearing 150 is disposed on relative position of the finger hole 11, which is the bottom of the ball 10. The core of bowling ball 100 is disposed in the ball 10. The rotating of the finger hole bar 110 can be more stable because the bottom bearing 150 is disposed on the bottom of the ball 10.

[0025] Please refer to FIG. 2. FIG. 2 shows bowling rolling schematic diagram. When the player pitch via the finger hole 11, the ball 10 will roll towards direction 21. At this time, because of the center bearing 120 is disposed between the rotation disk 130 and the finger hole bar 110, the rotation disk 130 would be affected to rotate by the kinetic energy of pitching. The center bearing 120 provides tiny resistance, so the rotation disk 130 would rotate towards direction 22 substantially. Next, the rotation of the rotation disk 130 would transmit the kinetic energy of direction 22 to the ball 10 via joint pole 140. Therefore, the ball 10 would also rotate towards direction 22, and the flying saucer is produced.

[0026] Therefore, the player pitches flying saucer with normal technique without using the special technique on the wrist. Besides, the core of bowling ball 100 is a central component in the bowling ball. The ball 10 can be manufactured by a normal method (E. g resin infusion) with the core of bowling ball 100.

[0027] According to Newton's first law, the objects in motion always keep constant velocity linear motion, the stationary object always keep stationary. In the instant application, the kinetic energy of vertical roll produced by pitching can be transformed into kinetic energy of horizontal roll, and the ball 10 can keep linear movement. The player just normally pitches the bowling ball then the flying saucer is produced, no longer needed special technique on the wrist. Moreover, the flying saucer would not be limited by Physiological Structure and Ergonomics. Everyone can use and enjoy the flying saucer with the core of bowling ball 100 of the instant application. It also can reduce sports injuries of the flying saucer and increase the entertainment of the bowling ball.

[0028] Those skilled in the art will readily observe that numerous modifications and alternatives of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the meters and bounds of the appended claims.
