Description

Bowling ball heart

A bowling ball center, especially a bowling ball center with a turntable.

The ten-pin bowling ball, also referred to as bowling in Chinese, is a ball-bearing ball (called a bowling ball) extended by a ball holder (called a bowling ball) along a wooden fairway or a synthetic (polyurethane) fairway. The ball spins the ball forward, the goal is to knock the ball down. There are three holes in the bowling ball that allow the ball holder to insert his finger into the ball while holding the ball, and the weight of the ball varies with the ball holder. Many countries have bowling tournaments for professional bowling, and about a million people around the world play bowling.

In bowling, the most common paths are "straight", "hook", and "flying saucer" (UFO, helicopter, spinning). Straight: A kind of ball path that novices who are new to bowling first learn first. When the fairway travels, it is straight, while the spherical rotation rotates along the direction of the ball. Hook: Also known as "hook", this course is different from a straight ball in that it has more destructive power than a straight ball, and the front half is the same as a straight ball when traveling on the fairway until it approaches the pin. When it is shifted to the left. UFO (Helicopter, Spinning): This ball is a game technique invented by professional bowling players in Taiwan, so this ball path is used by most Taiwan bowling players. It travels the same way as a straight ball, but the sphere rotates horizontally and is more powerful than a straight ball.

The skill of the UFO ball is to apply a lateral force to the bowling ball with the rotation of the wrist when throwing the bowling ball, so that the bowling ball rolls with a horizontal rotation. The ball can be struck by force, and the irregular collision of the pins can be used to achieve the goal of full collapse, that is, the flying saucer ball can effectively increase the probability of full collapse.

Since this course has been regarded internationally as the so-called Lucky all down, it is not recognized internationally, and South Korea has therefore restricted its players from banning flying saucer balls. According to the research of the American University of Bowling, in the logical calculation, the relationship between the sphere and the ball bottle must be a logical knockdown with a certain rule. The reason is like a domino effect before it can be considered a correct knockdown.

However, although the flying saucer ball is a technique that can improve the score, the wrist technique of throwing the flying saucer ball is actually not ergonomic and is prone to sports injuries, especially the wrist and joint parts are prone to swelling. On the other hand, due to the differences in physical structure, East Asian races are relatively easy to learn and use the skills of UFO balls, while white people and black people can hardly use the skills of UFO balls.

Therefore, how to overcome the above problems, make it easier for players to throw a flying saucer ball without causing sports injury, and make it easy for anyone to throw a flying saucer ball, it is worth thinking about for those with ordinary knowledge in the field.

The invention provides a bowling ball center, which enables players to throw flying saucer balls with conventional skills, and can greatly reduce the sports injuries generated by throwing flying saucer balls.

The invention provides a bowling ball core, which comprises a turntable, a center bearing, a finger-hole sleeve and a plurality of connecting posts. The center bearing is connected to the center of the turntable. The finger hole sleeve is connected with the center bearing. The connecting post is arranged through the turntable and is arranged in parallel with the finger hole sleeve.

In the above bowling ball center, the bowling ball center is covered in a sphere, and one end of the finger hole sleeve is aligned with the surface of the sphere.

In the bowling ball center, the center bearing and the finger hole sleeve are arranged on a central axis of the ball.

In the bowling ball center described above, the connecting post penetrates the sphere.

The above-mentioned bowling ball core further includes a plurality of connecting post bearings disposed between the connecting post and the turntable.

In the bowling ball core described above, the turntable further includes a plurality of shims, which are disposed between the turntable and the sphere, and the connecting post passes through the shims.

The present invention provides a bowling ball center. Through the setting of a turntable, a vertical force is converted into a lateral force, and the effect of a flying saucer ball is easier to produce.

Please refer to FIG. 1A. FIG. 1A illustrates an exploded view of a bowling ball center of the present invention. The bowling ball center 100 is wrapped in a sphere 10. The bowling ball center 100 includes a turntable 130, a center bearing 120, a finger-hole sleeve 110 and a plurality of connecting posts 140. The center bearing 120 is connected to the center of the turntable 130, while the finger sleeve 110 is connected to the center bearing 120, and the finger sleeve 110 passes through the turntable 130 and contacts the bottom bearing 150 at the bottom of the sphere 10. In other words, the turntable 130 is connected to the outside of the center bearing 120, and the finger hole sleeve 110 is inserted into the inside of the center bearing 120. Therefore, the turntable 130 and the finger hole sleeve 110 can rotate independently. In this embodiment, the center bearing 120 and the finger hole sleeve 110 are disposed on the central axis of the sphere 10, and one end of the finger hole sleeve 110 is aligned with the surface of the ball 10. The finger hole sleeve 110 also includes a finger hole 11, the finger hole 11 is located on the surface of the sphere 10. Further, the position of the finger hole 11 must be on the central axis of the sphere 10.

The connection posts 140 are disposed through the turntable 130, and a plurality of connection posts 140 are distributed in the radial direction of the turntable 130, and the long sides of the connection posts 140 are perpendicular to the radial direction of the turntable 130. Please refer to FIG. 1B, which is a schematic diagram of a turntable. The turntable 130 further includes a plurality of connection post bearings 131 and a plurality of spacers 132. The connection post bearings 131 are disposed between the connection post 140 and the turntable 130, and are sleeved on the position where the connection post 140 penetrates the turntable 130. The gasket 132 is disposed between the turntable 130 and the sphere 10, and the connection post 140 is disposed through the gasket 132.

Please refer to FIG. 1C. FIG. 1C is a schematic side view of the bowling center. The connecting post 140 is long enough to be connected to the sphere 10. Therefore, when the turntable 130 rotates, the turntable 130 rotates the sphere 10 through the connecting column 140, and the connecting column 140 is vertically arranged with the turntable 130. When the turntable 130 drives the connecting column 140 and the sphere 10 to rotate, the sphere 10 can effectively improve Torque. In addition, in order to comply with international bowling standards, all elements of the sphere 10 and the bowling center 100 are made of non-metallic materials. The preferred embodiment is a part made of Polyurethane or high molecular weight polyethylene (UPE) material. It can also be composed of a mix of cork and synthetic reinforced rubber, and the outer layer is surrounded by hard rubber, plastic or glass fiber.

In addition, in some embodiments, the bowling ball core 100 further includes a bottom bearing 150. The bottom bearing 150 is disposed at the relative position of the finger hole 11, that is, the bottom of the sphere 10. And when the bowling ball center 100 is set in the sphere 10, when the sphere 10 rotates, the bottom bearing 150 makes the rotation of the finger hole sleeve 110 more stable.

Please refer to FIG. 2, which illustrates a schematic diagram of a bowling ball rolling. When the player throws the ball with the finger hole 11, the sphere 10 will roll in the direction 21. When the sphere 10 is thrown, a center bearing 120 is provided between the turntable 130 and the finger hole sleeve 110. At this time, the turntable 130 will be affected by the kinetic energy of the pitching and rotate, and because the center bearing 120 provides less resistance, The turntable 130 is caused to rotate further in the direction 22. at this time, The rotation of the turntable 130 will transmit the kinetic energy in the direction 22 to the sphere 10 through the connecting post 140, and the sphere 10 will be rotated in the direction 22 at the same time, thereby generating the effect of a flying saucer ball.

Therefore, as long as the player uses conventional pitching techniques and does not need to use special wrist skills, he can throw a flying saucer ball. The bowling ball core 100 is used as the central part of the bowling ball. After the conventional resin infusion molding process, the outer ball 10 is formed, and the bowling ball can be completed.

According to Newton's first law of motion, in the law of inertia, an object in motion always maintains a constant-speed linear motion state, and a stationary object always maintains a static state, which is the law of conservation of linear energy. The bowling ball center 100 of the present invention passes through the arrangement of the turntable 130, the center bearing 120 and the connecting post 140. When the bowling ball center 100 is set in the sphere 10, the kinetic energy of vertical rolling during pitching can be converted into the kinetic energy of horizontal rotation And keep the sphere moving in a straight line. Players only need to throw a bowling ball to produce the effect of a flying saucer. No special skills are needed, nor is it limited to physiology and ergonomics. Any player can experience the fun of flying saucer balls. Will greatly reduce the sports injuries caused by UFO, and also improve the entertainment of bowling.
