Abstract
Description
Badminton racket grip Technical Field
[0001] This work relates to badminton rackets, specifically a type of badminton racket grip. Prior Technology
[0002] The grip of a badminton racket is for the user to hold and control the direction of the racket swing and the force of the hit. When operating a badminton racket, it is often necessary to switch between forehand and backhand or to perform wrist rotation.
[0003] The grip of a well-known badminton racket has a size configuration that results in poor hand coverage and makes it difficult for the fingers to control the smooth rotation of the grip. This causes a slight delay when the user is making high-speed forehand and backhand grip changes, making it difficult for the racket face to be accurately positioned and affecting the landing point of the shot, as well as the sensitivity and stability of the shot.
[0004] Therefore, it is necessary to provide a novel and advanced badminton racket grip to solve the above problems. Summary of the Invention
[0005] The main purpose of this invention is to provide a grip for a badminton racket that makes it easier for the user's hand to wrap around and control the racket.
[0006] To achieve the above objectives, this invention provides a badminton racket grip, comprising: a main body including a grip portion, a head, and a bottom, the head and the bottom being connected to opposite ends of the grip portion along an axial direction; the head being conical in shape; a top portion being provided at one end of the head away from the grip portion; the top portion having an opening; and, viewed along the axial direction, the bottom being polygonal in shape; the maximum outer diameter of the bottom portion ranging from 22.00 mm to 24.00 mm; the outer diameter of the top portion ranging from 8.00 mm to 10.00 mm; the main body defining an axially extending boundary line extending along the surface of the grip portion; the boundary line forming an angle with a conical surface of the head portion ranging from 8.00 degrees to 16.00 degrees; and a connecting portion connected to the top portion and extending inward into the grip portion; the connecting portion having a connecting hole communicating with the opening; the connecting hole for inserting a racket shaft of a racket frame.

[0008] The following examples illustrate possible implementations of this invention, but are not intended to limit the scope of protection sought by this invention. The prefixes "a" or "at least one" to the terms mentioned herein are not intended to limit the quantity, and may also be "multiple" depending on the requirements. Such variations in quantity are also within the scope of protection sought, and are therefore stated in advance.
[0009] Please refer to Figures 1 to 5, which show one embodiment of the present invention. The grip 1 of the badminton racket of the present invention includes: a main body 10 and a connecting part 20.
[0010] The main body 10 includes a grip portion 11, a head 12, and a bottom 13. The head 12 and the bottom 13 are connected to opposite ends of the grip portion 11 along an axial direction A. The head 12 is conical in shape. One end of the head 12 away from the grip portion 11 is provided with a top portion 14. The top portion 14 is provided with an opening 15. When viewed along the axial direction A, the bottom 13 is polygonal in shape. The maximum outer diameter dimension D1 of the bottom 13 ranges from 22.00 mm to 24.00 mm, and the outer diameter dimension D2 of the top portion 14 ranges from 8.00 mm to 10.00 mm. The main body 10 defines an axially extending boundary line B that extends along the surface of the grip 11. This boundary line B forms an angle θ with a conical surface 16 of the head 12, the angle θ ranging from 8.00 degrees to 16.00 degrees. Preferably, the conical surface 16 has a radially projected first projection dimension P1 ranging from 36.00 mm to 40.00 mm. The connecting portion 20 connects to the top portion 14 and extends inward into the grip 11. The connecting portion 20 has a connecting hole 21 that communicates with the opening 15, and the connecting hole 21 allows for the insertion of a racket shaft 31 of a racket frame 30. Specifically, the head 12 can be fitted with a conical cap.
[0011] This allows the structural forces between the shaft 31 and the grip 1 to be gradually distributed, forming a longer and more gently sloping conical transition area in the head 12, enhancing maneuverability and finger control. It also makes it easier for the user's hand to cover the grip 1 and improves the smoothness of finger control of the grip 1's rotation, while also making the overall design lighter.
[0012] Preferably, the main body 10 and the joint 20 are integrally formed from a composite material, which includes polyoxymethylene (POM) and nanomaterials (such as carbon nanotubes, nano-grade mineral powders or other nanomaterials), providing a lightweight and high-strength structure with excellent shock absorption.
[0013] The axial dimension L1 of one of the connecting holes 21 ranges from 55.00 mm to 65.00 mm. Preferably, the ratio of the axial dimension L1 of one of the connecting holes 21 to the first projected dimension P1 of the conical surface 16 in the radial direction ranges from 1.47 to 2.00 (preferably from 1.47 to 1.80), which significantly increases the depth to which the shaft 31 is inserted into the grip 1, thereby improving the connection stability between the shaft 31 and the grip 1 and enhancing the overall swing stability. Specifically, a locking hole 22 is provided on the outer periphery of the main body 10 radially corresponding to the connecting hole 21. The axial distance D3 from the locking hole 22 to one of the bottom 13 ranges from 135.00 mm to 143.00 mm. Furthermore, the locking hole 22 can be used to lock a fixing screw, allowing the fixing screw to be radially pressed against the shaft 31 for positioning, thus improving the fixing effect.
[0014] Preferably, the ratio of the outer diameter D2 of the top end portion 14 to the aperture R1 of the connecting hole 21 is in the range of 1.00 to 1.67. In this embodiment, the aperture R1 of the connecting hole 21 is in the range of 6.00 mm to 8.00 mm, so that the wall thickness of the top end portion 14 is maintained within an appropriate range and the structural strength is high.
[0015] The bottom 13 is octagonal, comprising four first short sides 131, two opposing second short sides 132, and two opposing long sides 133. The two second short sides 132 and the two long sides 133 are alternately arranged circumferentially. A first short side 131 connects an adjacent long side 133 and a second short side 132. Each first short side 131 is radially projected with a first short side projection dimension P2, ranging from 6.00 mm to 8.00 mm. Each second short side 132 is radially projected with a second short side projection dimension P3, ranging from 7.00 mm to 9.00 mm. Each long side 133 is radially projected with a long side projection dimension P4. The projected size ranges from 11.00mm to 13.00mm; preferably, the first distance D6 between one of the two long sides 133 ranges from 17.00mm to 20.00mm; the second distance D4 between one of the two first short sides 131 ranges from 22.00mm to 24.00mm; and the third distance D5 between one of the two second short sides 132 ranges from 22.00mm to 24.00mm. Through the configuration of different side lengths, the grip 1 cross-section has a more obvious directional characteristic, improving the efficiency of switching between forehand and backhand grips. Furthermore, the fingers can apply force against at least one of the long sides 133, at least one of the first short sides 131, or at least one of the second short sides 132, making the control of the grip 1 by the fingers more precise.
