Description

Bowling ball heart

A bowling ball core, in particular a bowling ball core with a power conversion dial.

10 bottles of bowling, also referred to as bowling in Chinese, is made by the ball-bearer to make the ball (called bowling) extend the wooden fairway or the synthetic (polyurethane) fairway, and the ten rounds of the fairway are arranged in an equilateral triangle. The ball rotates the ball forward, and the goal is to knock down the movement of the bottle. There are three holes in the bowling ball that allow the ball holder to insert a finger into the ball while holding the ball, and the weight of the ball varies from player to ball. In many countries there are bowling matches for professional bowling, and there are millions of people around the world playing bowling.

In bowling, the main common roads are "straight", "hook", "flying ball" (UFO, helicopter, spinning). Straight: A kind of ball that a newcomer who has just started to touch the bowling ball learns first, while the ball is moving in a straight line while the ball is rotating in the direction of the ball. Hook: Also known as "hook ball", this ball is different from a straight ball in that it has more destructive power than a straight ball, and the first half is the same as the straight ball when the fairway is traveling, until it approaches the bottle. At the time, it will shift to the left. UFO, Helicopter, Spinning: This ball is a kind of playing skill created by Taiwanese professional bowlers, so this ball is a kind of path used by most Taiwanese bowling players. It travels the same as a straight ball, but the spherical rotation rotates horizontally and is more destructive than a straight ball.

The skill of the flying saucer ball is to apply a lateral force to the bowling ball when the bowling ball is thrown, so that the bowling ball has a lateral rotation when it rolls, and when the ball is in contact with the bottle, it is transmitted through the lateral direction. The heart force can hit the ball and use the irregular collision of the bottle to achieve the purpose of full reversal, that is, the UFO ball can effectively increase the probability of full reversal.

Since this golf course has been recognized as the so-called lucky all down in the world, it is not recognized internationally, and South Korea has thus restricted its players from banned flying saucers. According to the research of the American Bowling University, the relationship between the sphere and the bottle must be a certain rule logic knockdown in the logic calculation. The reason is like the domino effect, which is regarded as the correct knockdown.

However, although the UFO ball is a skill to improve the score, the wrist technique of actually throwing the UFO ball is not ergonomic and is prone to sports injuries, especially the wrist and joint parts are prone to swelling. On the other hand, due to differences in physiological structure, East Asian races are more likely to learn and use the skills of flying saucer balls, whereas whites and blacks can hardly use the skills of flying saucers.

Therefore, how to overcome the above problems, making it easier for players to throw a flying saucer ball without causing sports injuries, and making it easy for anyone to throw a flying saucer ball is worthy of consideration in the field.

This creation provides a bowling ball that allows the player to cast a flying saucer ball with regular skill, which can greatly reduce the sports injuries caused by flying the ball.

The present invention provides a bowling ball core comprising a turntable, a center bearing and a plurality of connecting columns. The center bearing is inlaid in the center of the turntable. The connecting post is attached to the edge of the turntable.

FIG. 2 is a schematic view showing the bowling scroll.

The present invention provides a bowling ball core, and through the setting of the turntable, the vertical force is converted into a lateral force, which is more likely to produce a flying saucer ball effect.

Please refer to FIG. 1 , which illustrates the bowling ball of the present creation. The bowling ball 100 is wrapped in a sphere 10. The bowling ball core includes a turntable 110, a center bearing 120, a plurality of thrust bearings 130 and a plurality of first connecting posts 140. The turntable 111 is a ring type turntable having a hole in the center of the turntable 111. The center bearing 120 is inlaid in the hole. The center bearing 120 includes a movable end 121 and a fixed end 122. The movable end 121 is embedded in the hole of the turntable 111, and the fixed end 122 is connected to the ball 10. When the ball 10 rotates, the turntable 110 will rotate due to the influence of the movable end 121. In the preferred embodiment, the center bearing 120 will be disposed on the centerline of the ball 10, that is, the axis of rotation of the movable end 121 will overlap the centerline of the ball 10, and the fixed end 122 will be coupled to one of the fingers of the ball 10. Hole 11.

The thrust bearing 130 is disposed at the edge of the turntable 110, and the thrust bearing 130 is disposed in parallel with the turntable 110. The thrust bearing 130 is disposed between the turntable 111 and the ball 10, and the thrust bearing 130 is disposed. The rotation of the turntable 110 can be made smoother. In an embodiment, the turntable 110 further includes a plurality of pin holes 111 and pins 112. The latch 111 is disposed through the pin hole 112, and the pin 111 is connected between the ball 10 and the turntable 110 to conduct a portion of the lateral force.

The connecting post 140 is attached to the edge of the turntable 110 and is inserted on the turntable 110. Further, the long sides of the connecting post 140 are disposed in parallel with the radial direction of the turntable 110. That is, after the connecting post 140 is disposed on the turntable 110, the turntable 110 and the connecting post 140 may assume a shape similar to a rudder. In the present embodiment, there are four connection posts 140, and in other embodiments, eight. One end of the connecting post 140 is connected to the turntable 110, and the other end is connected to the ball 10.

In summary, the turntable 110 is coupled to the ball 10 via the latch 112 and the connecting post 140. And because the center line of the center bearing 120 is the finger hole 11 corresponding to the ball 10. That is, the turntable 110 will rotate about the axis of the finger hole 10. Such a configuration causes an angular difference between the direction of rotation of the turntable 110 and the direction of rotation when the ball 10 is thrown.

In another embodiment, the bowling ball 100 further includes a counterweight disposed at the bottom of the bowling ball 100. When disposed in the ball 10, the counterweight is located at the relative position of the finger hole 11, and The counterweight is made of a high density non-metallic material. The setting of the counterweight can stabilize the direction of rotation of the turntable 110. In addition, in order to comply with international bowling specifications, the sphere 10 and all components of the bowling ball 100 (including components such as bearings) are made of a non-metallic material. The preferred embodiment is a part made of a polyurethane or a high molecular weight polyethylene (UPE) material. It can also be composed of a mixture of cork and synthetic reinforced rubber, and the outer layer is surrounded by hard rubber, plastic or fiberglass.

Please refer to FIG. 2 , which is a schematic diagram of the bowling scroll. When the player throws the ball with the finger hole 11, the ball 10 will roll toward the direction 21. Since the inner bowling ball 100 has a rotatable turntable 110, the center bearing 120 on the turntable 110 and the thrust bearing 130 provide less resistance, making the turntable 110 larger. The amplitude turns in the direction 22 . The rotation of the turntable 110 is transmitted to the ball 10 via the connecting post 140, causing the ball 10 to simultaneously rotate in the direction 22, further producing the effect of the flying saucer ball. Therefore, players can cast a flying saucer ball without using special wrist techniques using regular pitching techniques. The bowling ball 100 is used as a central part in the bowling ball. After the conventional resin infusion forming process, the outer sphere 10 is formed, and the bowling ball can be completed.

According to Newton's first law of motion, the object in motion in inertia law always maintains a constant-speed linear motion state, and the stationary object always remains stationary, that is, the law of linear energy conservation. The bowling ball 100 of the present invention is designed by the turntable 110 and the connecting post 140. When the bowling ball 100 is disposed inside the bowling ball 10, the vertical rolling kinetic energy during the pitching can be converted into the horizontal rotating kinetic energy, and Keep the sphere moving in a straight line. Players can cast a bowling ball to produce a flying saucer ball. No special skills are required, nor is it limited to physiological structure and ergonomics. Any player can experience the fun of flying saucer balls. It will greatly reduce the sports damage caused by the flying saucer ball, and also improve the entertainment of the bowling ball.
