Multi-layer golf ball with large deformation

The present invention is a multi-layer golf ball with a large amount of deformation, in particular, a diameter of the outermost diameter of the core layer is set to be less than 41.3 mm (Millimeter), thereby forming a multi-layer ball of at least two layers, and has Easily exert the effect of its deformation.

According to the modern people, the modern life is increasingly focused on the balance between leisure life and work. Therefore, by engaging in swimming, mountain climbing, ball games, etc., it is possible to eliminate work stress and fatigue, while exercising physical fitness and health. Mild and regardless of age and gender, it has become a favorite sport for all people. In the course of golf, in addition to the athletes' own skills, golf equipment is also an important factor in golf. In this case, the elasticity, hardness, stability and durability of the sphere must be considered. The above items will affect the feel of the athlete when hitting the ball, the distance over which the sphere flies, and the stability of the ground.

However, the general golf ball structure is mostly a double-layered ball, including a spherical core and a shell layer covering the center of the ball, and the ball core is made of a rubber with better elasticity. However, due to the general If the outer diameter of the center of the ball is too large, the overall elasticity and deformation of the golf ball are greatly reduced, so that the hand feel is not good when hitting, and the flight and rolling distance will be affected; and if the amount of deformation is to be fully exerted, the swing is performed. Speeds of at least 105 miles per minute (mph) are not conducive to practice or competition.

In view of this, the creator specially researches and improves the golf ball, and improves the above problems with a better design. After long-term research and development and continuous testing, the author has begun to ask about the creation. world.

The core layer can be made of elastic rubber. Therefore, the swing speed of the swinger only needs about 90 miles per minute (mph), so that the deformation of the creation can be fully utilized. When the hardness of the innermost core of the heart layer is smaller than that of the inner core of the outer layer, the impact can be improved, and the amount of deformation after hitting the ball is large, so that the back spin is large, so that the creation stays in the air for a longer time. Therefore, the flight distance can be lengthened, thereby increasing the distance of landing after hitting the ball.

2. In order to enable the golfers to select a suitable golf ball, the creation system may be coated with an intermediate layer between the spherical shell and the spherical core layer to form at least three layers of the plurality of balls for each swing. The golfers of different layers are selected according to their needs or habits, thereby improving the applicability of the creation.
