Description

Technical Field

[0001] This invention relates to a golf club head element, and more particularly to a club head striking panel. Background Technology

[0002] To provide golf clubheads with better hitting performance, control, and feel, modifications are typically made to the striking face, such as adjusting its thickness or applying a surface coating. Existing cup-face designs feature a skirt extending from the perimeter of the striking face towards the top, bottom, or toe of the clubhead to enhance its hitting performance. However, golfers continue to demand higher hitting performance, and these adjustments alone are no longer sufficient to meet their needs.

[0003] Therefore, there is indeed a need to improve the existing clubhead striking panels. Summary of the Invention

[0004] To address the aforementioned problems, the purpose of this invention is to provide a clubhead striking panel that can further improve the striking performance of golf clubheads.

[0005] The directions or similar terms used throughout this invention, such as "front," "back," "left," "right," "top," "bottom," "inner," "outer," and "side," are mainly for reference to the directions in the accompanying drawings. These directions or similar terms are only used to assist in explaining and understanding the various embodiments of this invention and are not intended to limit this invention.

[0006] The use of the quantifiers “a” or “an” for the elements and components described throughout this invention is for convenience and to provide the general meaning of the scope of the invention; in this invention, it should be interpreted as including one or at least one, and a single concept also includes multiple cases, unless it clearly means otherwise.

[0007] The terms "combination," "integration," or "assembly" used throughout this invention mainly refer to forms such as those in which the components can be separated without damaging them after connection, or those in which the components cannot be separated after connection. Those skilled in the art can choose the appropriate term based on the material of the components to be connected or the assembly requirements.

[0008] The clubhead striking panel of the present invention includes: a panel body having a striking portion having a striking surface, the panel body having at least one extension formed by extending in the opposite direction from the periphery of the striking portion toward the striking surface, the at least one extension and the striking portion surrounding a space; and a groove located in the at least one extension, such that the outer surface of the at least one extension has a slot that does not communicate with the space.

[0009] Therefore, the clubhead striking panel of the present invention, by having the groove in the at least one extension, can further increase the ball speed at impact and reduce the backspin force of the ball after impact, thereby increasing the rolling distance of the ball after impact, and thus achieving the effect of improving the striking panel's hitting performance.

[0010] The groove extends along the periphery of the striking part, with an extension distance of 40–100 mm. This groove absorbs the striking stress of the panel body, thereby increasing the ball's speed and rolling distance.

[0011] The extension portion extends from the striking part to its end with a length of 10 to 65 mm. This provides sufficient length for the groove to be positioned.

[0012] The groove has a width of 2 to 20 mm from the end of the at least one extension to the striking part. This allows the panel body to have a better rebound coefficient when hitting the ball, thereby reducing energy loss after impact.

[0013] The groove and the striking part are spaced apart by a distance of 3 to 20 mm. This prevents the groove from being too close to the striking part, which would reduce the striking power of the striking part.

[0014] The groove has a virtual plane passing through its opening, and the groove has two opposing inner walls at the end of the at least one extension in the direction to the striking part, the two inner walls being non-perpendicular to the plane. Thus, the groove can increase the ball's release speed and its rolling distance.

[0015] Both inner walls are inclined towards the striking surface. This groove resists the stress generated by the ball hitting the striking surface, allowing the ball to bounce back quickly and increasing its speed.

[0016] Both inner walls are inclined away from the striking point. In this way, the groove can further extend the stress generated by the striking point to the rear and then rebound, thereby improving the feel of the shot.

[0017] The two inner walls extend and connect at an angle away from the groove opening. This design increases the ball's launch speed and rolling distance.

[0018] The groove protrudes into the space and has one end facing the direction of the striking part. In this way, the groove can resist the stress generated by the striking part, thereby allowing the ball to rebound quickly and increasing its speed.

[0019] The groove protrudes into the space and has one end facing away from the striking part. In this way, the groove can further amplify the stress generated by the striking part upon impact, extending it backward and creating a rebound, thereby enhancing the feel of the shot.

[0020] The groove has several support frames. These support frames can further increase the ball's release speed and rolling distance. Attached Figure Description

Detailed Implementation

[0023] To make the above and other objects, features and advantages of the present invention more apparent and understandable, preferred embodiments of the present invention are described below in detail with reference to the accompanying drawings; in addition, the same symbols in different drawings are considered to be the same and their descriptions will be omitted.

[0024] Please refer to Figure 1 As shown, it is the first embodiment of the clubhead striking panel of the present invention, which includes a panel body 1 and a groove 2, the groove 2 being recessed on the surface of the panel body 1.

[0025] The panel body 1 can be made of metal materials such as titanium alloy or steel, and can be formed by, for example, forging, casting, or 3D printing. The panel body 1 has a striking portion 11, the thickness of which can be 2-6 mm. The striking portion 11 can be generally flat and has a striking surface 11a. The panel body 1 has at least one extension 12, which can be formed by extending from the periphery of the striking portion 11 in the opposite direction to the striking surface 11a. The at least one extension 12 and the striking portion 11 can surround each other to form a space S. Thus, the panel body 1 can be made into a cup-shaped hitting panel.

[0026] Please refer to Figure 1 , Figure 2 As shown, for example, a top edge 11b of the striking part 11 can be located at the crown of the golf club head, and a bottom edge 11c of the striking part 11 can be located at the sole of the golf club head. The at least one extension 12 can be located at the top edge 11b so that the at least one extension 12 can connect to the crown of the golf club head. Alternatively, the at least one extension 12 can be located at the bottom edge 11c so that the at least one extension 12 can connect to the sole of the golf club head. Or, there can be two extensions 12, with the two extensions 12 located at the top edge 11b and the bottom edge 11c respectively. The present invention is not limited to these two extensions.

[0027] More specifically, the thickness of the at least one extension 12 can be 1 to 6 mm, and the thickness of the at least one extension 12 adjacent to an end 12a can be 1 to 4 mm. In addition, the at least one extension 12 can be connected to the striking part 11 by a connecting part 13, the thickness of which can be 1 to 6 mm.

[0028] Continue to refer to Figure 1 , Figure 2As shown, the groove 2 can be located in the at least one extension 12. The groove 2 can be an elongated groove. For example, the groove 2 can be located in the extension 12 adjacent to the top edge 11b, or the groove 2 can be located in the extension 12 adjacent to the bottom edge 11c. In this embodiment, the groove 2 is located in the extension 12 adjacent to the bottom edge 11c for illustration. The extension length L of the extension 12 from the bottom edge 11c of the striking part 11 to the end 12a can be 10 to 65 mm, so that the extension 12 has sufficient length to provide the groove 2. A portion of the extension 12 can protrude into the space S to form the groove 2, and the outer surface of the extension 12 has a slot 21. Furthermore, the inner surface of the striking part 11 can have a virtual first plane P1, and the slot 21 can have a virtual second plane P2. The extension length L can be the vertical distance from the intersection of the first plane P1 and the second plane P2 to the end 12a.

[0029] The groove 2 can extend along the periphery of the striking part 11. In this embodiment, the groove 2 can extend laterally along the bottom edge 11c of the striking part 11, that is, the groove 2 can extend along the panel body 1 in the direction from the toe to the heel of the golf club head. The extension length of the groove 2 can be 40-100 mm. Furthermore, the cross-section of the groove 2 can be rectangular, and the groove opening 21 of the groove 2 has a groove width W, which can be 2-20 mm. In this way, the panel body 1 can have a better rebound coefficient when hitting the ball, so as to reduce the loss of energy after the impact. In addition, the groove 2 and the striking part 11 have a distance D. Furthermore, the groove 2 has the distance D at the intersection of the first plane P1 and the second plane P2. The distance D can be 3-20 mm to avoid the groove 2 and the striking part 11 being too close, causing a decrease in the hitting power of the striking part 11. Thus, the groove 2 can absorb the impact stress of the panel body 1, thereby increasing the ball speed and the ball's rolling distance, thus improving the ball's hitting distance. Tests have shown that compared to a hitting panel without the groove 2, the hitting panel of this invention can increase the ball speed by 3% and reduce the backspin force by 300 rpm when hitting the ball.

[0030] Please continue reading. Figure 3As shown, preferably, the groove 2 has two opposing inner walls 2a in the direction from the end 12a of the at least one extension 12 to the striking part 11. These two inner walls 2a are not perpendicular to the second plane P2, allowing the groove 2 to be inclined towards the striking part 11, or inclined away from the striking part 11. Furthermore, both inner walls 2a can be inclined towards the striking part 11, thus the groove 2 can resist the stress generated by the striking part 11, allowing the ball to rebound quickly and increasing its speed. Alternatively, both inner walls 2a can be inclined away from the striking part 11, thus the groove 2 can further extend the stress generated by the striking part 11 backward before rebounding, thereby improving the feel of the shot.

[0031] Furthermore, the groove 2 can also have several support frames 22, which can be formed by 3D printing. These support frames 22 can be arranged in a regular or irregular staggered pattern to form several grid-like gaps. In this way, the support frames 22 can further increase the ball's release speed and rolling distance. Tests have shown that using these support frames 22 can increase the ball's rolling distance after impact by 1-2 yards.

[0032] Please refer to Figure 4 , Figure 5 As shown, this is a second embodiment of the clubhead striking panel of the present invention. This embodiment is largely the same as the first embodiment described above. In this embodiment, the two inner walls 2a extend and connect in a direction away from the groove 21, forming an included angle θ, so that the cross-section of the groove 2 can be triangular. The groove 2 protrudes into the space S and may have an end 2b, which may face the striking part 11, so that the groove 2 can resist the stress generated by the striking part 11 when it hits the ball, thereby allowing the ball to be rebounded quickly and increasing the ball speed. Alternatively, the end 2b may face away from the striking part 11, so that the groove 2 can further extend the stress generated by the striking part 11 when it hits the ball backward and then rebound, thereby improving the feel of the shot.

[0033] Please refer to Figure 6 As shown, this is the third embodiment of the clubhead striking panel of the present invention. This embodiment is largely the same as the first embodiment described above. In this embodiment, the vertical distance T1 from the opening 21 of the groove 2 to the bottom of the groove is less than the thickness T2 of the at least one extension 12. Thus, the groove 2 can be formed without significant deformation of the at least one extension 12, further improving the strength of the at least one extension 12. It is worth mentioning that the groove 2 in the second and third embodiments described above can have several support frames 22 as described in the first embodiment, thereby further improving the ball speed and the ball's rolling distance.

[0034] In summary, the clubhead striking panel of the present invention, by having the groove in at least one extension, can further increase the ball speed at impact and reduce the backspin force of the ball after impact, thereby increasing the rolling distance of the ball after impact and achieving the effect of improving the striking panel's hitting performance.

[0035] Although the present invention has been disclosed using the above preferred embodiments, it is not intended to limit the invention. Any modifications and alterations made by those skilled in the art to the above embodiments without departing from the spirit and scope of the invention are still within the scope of protection of the present invention. Therefore, the scope of protection of the present invention includes all changes within the meaning and equivalent scope of the appended claims. Furthermore, when the above embodiments can be combined, the present invention includes any combination of embodiments.
