Problems solved by technology

[0002] Regular golf balls are generally made of synthetic rubber inside and hard plastic with pits covering the outer layer. The weight is about 45 grams, and the diameter is generally 42.6-42.8 mm. It can fly to a distance of nearly 300 meters. This characteristic determines that it is impossible to practice hard hitting in a small space such as a living room with a regular golf ball.
In order to solve this problem, hollow lightweight plastic golf balls and light and soft PU foam golf balls have become a choice for indoor practice. However, due to the low resistance chara

Example Embodiment

Specific implementation 2:

[0026] Such as figure 2 As shown, the sphere structure of the present invention for reducing the flying speed of a golf ball includes foamed PU3, cork 2, PU skin 1 and decelerating device 5. In order to obtain good hitting performance, it is best to place the hitting surface on the opposite side of the decelerating device 5. The material with a density similar to cork 2 is used, and the foamed PU3 can be of any shape to match the goal of reducing the quality of the golf ball 9, that is, only the middle layer of the hitting surface hemisphere can be made of cork 2 with a thickness of 8 mm, and the other hemispheres All foamed PU3 is used and extended to fill the inner side of the cork 2 in the hemisphere of the hitting surface and glued to the inner surface. The deceleration device 5 is composed of feathers 14, feather roots 8, tie ropes 10 and spherical head guard 11. The number, length and angle of the feathers 14 with the central axis can be adjusted...

Specific implementation mode 3:

[0027] Such as image 3 Shown: The sphere structure of the present invention for reducing the flying speed of a golf ball includes a decelerating device 5 and a PU foam ball 9. The decelerating device 5 is a radial belt with 12 skeletons 6 and sectors 7 alternately connected to the central axis at 20°, The frame 6 of the deceleration device 5 is 38 mm long, and its large-diameter end is flush with the upper end of the 30 mm-long sector 7; the 8 mm long part of the bottom end of the frame 6 is not connected with the sector. The end of the frame 6 is connected to the PU foam sphere 9 is formed into one body. The outer surface of the PU foamed ball 9 has a dimple 12 of a regular golf ball, and the diameter is controlled to be 42.6-42.8 mm.

Abstract

The invention provides a method for reducing the flying speed of a golf ball as well as a spherical structure, relating to the golf sports field. The method comprises: a decelerating device which is symmetrical in mass and distance along a central axis is arranged on a golf ball body, the device is an actinoid girdle and forms an angle of less than 90 degrees with the central axis, besides the flying speed of the golf ball is greatly reduced, the aerodynamics features for stabilizing flying can also be maintained, thereby making a heavy hit on the golf ball during simulative practice in a narrow space such as in a room possible, and solving the problem that the current golf ball practice depends heavily on course size, as well as being very useful for popularizing and developing the golf sports.

Description

Technical field: [0001] The invention relates to the field of golf, in particular to a method capable of reducing the flying speed of a golf ball and a golf ball structure capable of practicing vigorous hitting in indoor actual combat. Background technique: [0002] Regular golf balls are generally made of synthetic rubber inside and hard plastic with pits covering the outer layer. The weight is about 45 grams, and the diameter is generally 42.6-42.8 mm. It can fly to a distance of nearly 300 meters. This characteristic determines that it is impossible to practice vigorously hitting the ball in a small space such as a living room with a regular golf ball. In order to solve this problem, hollow lightweight plastic golf balls and light and soft PU foam golf balls have become a choice for indoor practice. However, due to the low resistance characteristics of the above-mentioned golf balls, the ball speed after hitting is still very fast, the rebound force is relatively large a...
