[0001] This utility model relates to golf clubs and grips. Background Technology

[0002] Existing round-section golf clubs are prone to twisting during the swing, causing the clubhead to deviate from its intended direction and affecting accuracy. They also result in energy loss at impact, impacting distance. Furthermore, the round grip is susceptible to slippage when wet, negatively affecting the swing experience. Utility Model Content

[0003] To address the aforementioned technical problems, the purpose of this utility model is to provide a golf club and grip with a non-circular cross-section. Specifically, through optimized designs such as the non-circular cross-section design of the club and grip, the hitting experience and performance are enhanced.

[0004] This utility model is achieved through the following technical solution:

[0005] A golf club and grip with a non-circular cross-section include a striking head, a club, and a grip. The club is inserted into and connected to the striking head. The front end of the club has a circular cross-section, while the rear end has a non-circular cross-section. The grip is made of a flexible material and extends from the non-circular cross-section of the rear end of the club to the end face of the club. The internal cross-section of the grip has a non-circular cross-section that matches the club. The surface of the grip has raised ribs arranged at equal intervals to prevent slippage, and the height of each raised rib is 0.5 mm.

[0006] In this embodiment of the invention, the rear end portion of the cue stick has a hexagonal cross-section.

[0007] In this embodiment of the utility model, the length of the handle is in the range of 260-265mm.

[0008] In this embodiment of the invention, the rear end portion of the grip is provided with a first arc-shaped surface, and the cross-section of the first arc-shaped surface gradually increases from the end closer to the club to the end farther away from the club.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Referring to the accompanying drawings, a golf club and grip with a non-circular cross-section are disclosed, including a striking head 1, a club 2, and a grip 3. The club 2 is inserted into and connected to the striking head 1. The front end portion 21 of the club 2 has a circular cross-section, while the rear end portion 22 has a non-circular cross-section. In a specific embodiment of this invention, the rear end portion 22 has a hexagonal cross-section. Furthermore, the grip 3 is connected to the club 2 and is made of a flexible material. In a preferred embodiment, the grip 3 can be made of rubber, EVA, or a special synthetic material. The grip 3 extends from the non-circular cross-section of the rear end portion 22 of the club 2 to the end face of the club 2, and the internal cross-section of the grip 3 has a non-circular cross-section that matches that of the club 2. Additionally, the surface of the grip 3 is provided with evenly spaced, raised ribs 31 for preventing slippage, and the height of each raised rib 31 is 0.5 mm, as indicated by point B. This application, through the aforementioned structural design, significantly enhances structural stability, optimizes power transmission efficiency, and improves durability and fatigue resistance via the hexagonal interlocking structure of the club 2 and grip 3. Specifically, the hexagonal cross-section design, compared to the traditional circular design, provides a larger contact area and stronger torsional resistance, reducing the relative displacement between the club 2, grip 3, and impact head 3 during the swing, ensuring consistent power transmission. The hexagonal design also distributes stress more evenly, avoiding deformation or breakage caused by localized stress concentration, allowing the player's swing power to be transferred to the impact head 1 more efficiently, improving hitting distance and accuracy. Furthermore, the hexagonal structure is less prone to metal fatigue due to long-term torsion or bending compared to a circular design, extending the club's lifespan, making it particularly suitable for frequent use or high-intensity competition scenarios.

[0031] Furthermore, the flexible grip 3 better conforms to the curve of the hand, reducing hand fatigue during prolonged gripping, especially in hot weather or during high-intensity swings, significantly improving comfort. Simultaneously, the flexible material increases friction, helping players maintain a stable grip in wet environments, such as rainy days or when hands are sweaty, preventing slippage and enhancing stability. More importantly, the flexible grip 3 design also absorbs some vibration, reducing impact on the wrist and arm, while providing clearer clubhead feedback, helping players control the power and direction of their shots more precisely.

[0032] Furthermore, the 0.5mm raised rib 31 design increases the surface roughness of the grip 3 through microstructure, allowing players to grip the club more firmly, especially in wet environments, effectively preventing slippage and reducing mis-hit errors caused by an unstable grip. Simultaneously, the micro-raised rib 31 structure transmits clearer contact information from the impact head 1 during the swing, helping players to more acutely perceive the contact point between the impact head 1 and the ball, thus enabling more precise control of the power and direction of the shot. In addition, the micro-raised rib 31 design disperses localized pressure during gripping, preventing excessive wear on any single area and extending the lifespan of the grip 3. The 0.5mm height design ensures sufficient friction without compromising grip comfort or causing an overly rough feel due to excessive protrusion, making it a practically proven and reasonable design.

[0033] Furthermore, the grip 3 has a length range of 260-265mm, as shown at point C. Based on human hand size data, the average palm width for adult men is approximately 71-97mm, and for women, approximately 65-85mm. A grip length of 263mm covers the main force area of ​​the hand, from the palm to the base of the fingers. This length allows the fingers to naturally bend and wrap around the grip, avoiding overextension due to a too-short grip or reduced grip concentration due to a too-long grip, providing stable grip support. The 263mm grip length is designed for players with medium hand sizes, balancing comfort and functionality, and is suitable for most amateur and professional players.

[0034] Furthermore, the rear end of the grip 3 is provided with a first arc-shaped surface 36, the cross-section of which gradually increases from the end closer to the club 2 to the end farther away from the club 2. This first arc-shaped surface 36 is designed based on the mechanical characteristics and ergonomic principles of a golf swing. It optimizes grip stability, distributes grip pressure, and guides correct swing motion. By increasing the contact area at the rear end, it disperses localized pressure from the palm on the grip, reducing fatigue caused by prolonged gripping. The design of the first arc-shaped surface 36 also guides the golfer to maintain stable contact between the palm and the grip during the swing, reducing motion distortion caused by improper grip design.

[0035] Furthermore, the rear end of the grip 3 is provided with a straight end 38 with an unchanged cross-section, and the raised ribs 31 are arranged to stop at the straight end 38.

[0036] Furthermore, the front end of the grip 3 is provided with a second arc-shaped surface 37, the cross section of which gradually increases from one end near the striking head 1 to the other end away from the striking head 1, and the protruding ribs 31 extend from the rear end of the second arc-shaped surface 37.

[0037] The roughened surface of Grip 3 is designed to increase friction, helping players grip the club more stably. However, the lowest part of Grip 3 typically doesn't need the roughened surface, as this part primarily serves a support function rather than directly contributing to the grip. Retaining the blank area reduces unnecessary friction, allowing for smoother power transfer during the swing. Furthermore, the curved blank area of ​​Grip 3 makes it look cleaner and more streamlined. This design not only aligns with modern aesthetic trends but also enhances the overall aesthetics of the club.

[0038] Furthermore, the striking head 1 is a golf clubhead, and its striking face features "mountain"-shaped ribs 11. This "mountain"-shaped rib design, by altering the contact between the clubface and the ball, reduces offset and sidespin at impact. Its unique groove arrangement guides the striking head 1 to a more stable initial trajectory at impact, particularly suitable for long irons and woods, helping players maintain directional control during long-distance shots. In addition, the "mountain"-shaped rib 11 can also influence the ball's spin rate by changing the groove depth and spacing depending on the situation, thereby altering spin control. For example, when using short irons near the green, the rib design increases backspin, causing the ball to stop faster after landing; while when using woods on the tee, adjusting the rib parameters reduces sidespin, increasing distance. Furthermore, when the golf ball contacts the clubface of the clubhead 1, the "mountain"-shaped ribs 11 create micro-deformation spaces, more efficiently converting the impact force into the ball's flight energy. This design is particularly crucial in drivers, enabling the ball to achieve higher initial velocity and greater distance while reducing energy loss. Simultaneously, the density and angle of the rib arrangement can be flexibly adjusted according to the shot's needs. On wet or rough surfaces, denser ribs increase friction, preventing ball slippage; while on dry hard courses, a slightly lower rib density enhances the crispness of the shot and improves feedback. Finally, the "mountain"-shaped ribs 11 reduce wear on specific areas of the clubface by dispersing the impact force. This design also ensures a consistent coefficient of friction on the clubface after multiple shots, guaranteeing stable performance and extending the overall lifespan of the club.

[0039] In the specific design of this application, the spacing between the raised ribs 31 is 5mm, as indicated by point D. The length of each raised rib 31 is also 5mm, as indicated by point E. The raised rib 31 is a symmetrical structure that gradually bulges from both ends towards the middle, with the highest point in the middle being 0.5mm. This regular array of raised ribs 31 guides the fingers to natural positioning, reducing the tendency to slip during grip, and is particularly suitable for maintaining grip stability during fast swings. Furthermore, the structural design of the raised ribs 31 ensures direct power transfer during impact. The symmetrical, arc-shaped transition reduces stress concentration, allowing energy to be transferred more efficiently to the impact head 1. Finite element analysis verifies that this shape provides uniform stress distribution during deformation, offering sufficient support while preventing material fracture. In addition, the symmetrical, arc-shaped transition design offers high tolerance for grip angles, suitable for players with different swing styles, providing good feedback especially among golf beginners and professionals.

[0040] The straight end 38 at the rear of the grip 3 in this application has a maximum diameter of 28mm, as indicated by F. A small hole with a diameter of 3mm is provided in the middle of this straight end 38, as indicated by G in the figure. The bottom wall thickness of the rear end of the grip 3 is 3mm, as indicated by H in the figure. The hexagonal shape of the rear end portion 22 of the club 2 has a perimeter of 45.55mm, a longitudinal width of 15.09mm, as indicated by I in the figure, and a lateral width of 13.34mm, as indicated by J in the figure. Of course, slight tolerances are allowed in the dimensions of the grip 3 and the club 2. The design of these dimensions allows for better control of the swing rhythm, ensuring sufficient wrist movement space while limiting excessive wrist rotation, helping golfers better control the swing rhythm and power. The size and shape of the hexagonal insertion structure directly affect the vibration transmission during impact. The hexagonal design, through its specific contact surface size, can more effectively absorb excess vibration, resulting in clearer feel feedback. To increase grip comfort, the appropriately sized interlocking structure helps balance the overall center of gravity of the club, improving comfort and stability when holding it.
