Description

Technical Field

[0001] The invention relates to a golf club head, in particular to a club head with a counterweight. Background Art

[0002] When manufacturing a golf club head, in order to change the balance of the club and control the direction and speed of the serve, the worker may set a counterweight block on a golf club body, and use the counterweight block to change the center of gravity of the club and correct the trajectory of the shot, thereby enabling the hitter to have a better hitting performance. However, according to the various conditions of the hitter's shot and the different hitting strategies, the existing club head with a counterweight block is still not enough to meet the hitter's needs in terms of hitting stability. Therefore, the weight and position of the counterweight block need to be further adjusted to provide the hitter with stability in hitting. In view of this, it is necessary to provide a club head with a counterweight block to meet the needs of today's hitters. Summary of the invention

[0003] To solve the above problems, an object of the present invention is to provide a club head with a weight block, which can have better hitting stability.

[0004] The elements and components described throughout the present invention use the quantifiers "a" or "an" only for convenience of use and to provide a general meaning of the scope of the present invention; in the present invention, they should be interpreted as including one or at least one, and a single concept also includes multiple situations, unless it is obvious that it means otherwise.

[0005] The similar terms "combination", "assembly" or "assembly" mentioned throughout the present invention mainly include the connection that can be separated without destroying the components, or the connection that makes the components inseparable, etc., which can be selected by technicians in this field according to the materials of the components to be connected or the assembly requirements.

[0006] The club head with a counterweight block of the present invention comprises: a club head body, the club head body having a striking face plate portion and a shaft; and at least one counterweight block, which is combined with at least one combining groove of the club head body, the total weight of the at least one counterweight block is 40-85% of the total weight of the club head, and after the at least one counterweight block is combined with the club head body, the club head has a center of gravity, the vertical distance between the center of gravity and a center line of the shaft of the shaft is 35-55 mm, and the vertical distance from the center of gravity to the striking face plate portion is 12-55 mm.

[0007] Therefore, the club head with a counterweight block of the present invention, after the at least one counterweight block is set on the club head body, forms a predetermined vertical distance between the center of gravity of the club head with a counterweight block and the center line of the handle of the club head body, and a predetermined vertical distance between the center of gravity and the hitting face plate of the club head body. In this way, the moment of inertia of the club head when hitting the ball can be further increased, and the back spin force when hitting the ball can be reduced, so as to achieve better hitting stability and controllability.

[0008] Wherein, the club head body is a putter head. Thus, the at least one counterweight block can enable the hitter to have better ball control when pushing the ball with the club head.

[0009] The density of the club head body is 1-5 g / cm3. Thus, the club head body can only account for 15-60% of the total weight of the club head, which has the effect of increasing the control weight margin of the at least one counterweight block.

[0010] The total weight of the at least one counterweight block is greater than the weight of the club head body. Thus, when the club head body is a putter head, the effect of putting a ball can be performed more stably.

[0011] The total weight of the club head is 320-380 g, and the total weight of the at least one counterweight block can be 128-323 g. Thus, the at least one counterweight block has a better counterweight adjustment range.

[0012] The club head body is made of magnesium alloy, and the total weight of the at least one counterweight is 80-85% of the total weight of the club head. Thus, the at least one counterweight has a better weight adjustment range and can meet the requirements of club head bodies of different materials.

[0013] The club head body is made of aluminum alloy, and the total weight of the at least one counterweight is 65-70% of the total weight of the club head. Thus, the at least one counterweight has a better counterweight adjustment range and can meet the requirements of club head bodies of different materials.

[0014] The club head body is made of titanium alloy, and the total weight of the at least one counterweight is 40-50% of the total weight of the club head. Thus, the at least one counterweight has a better weight adjustment range and can meet the requirements of club head bodies of different materials.

[0015] There are two at least one counterweight, and the two counterweights are respectively adjacent to a toe and a heel at two ends of the hitting panel. In this way, the hitting panel can have a larger sweet spot.

[0016] The vertical distance between the at least one counterweight and the hitting panel portion is 60-90 mm. In this way, the at least one counterweight can be relatively far away from the center of gravity to further enhance the effect of the moment of inertia of the club head when hitting the ball.

[0019] In order to make the above and other objects, features and advantages of the present invention more obvious and easy to understand, the preferred embodiments of the present invention are specifically cited below and described in detail with reference to the accompanying drawings; in addition, those marked with the same symbols in different drawings are regarded as the same and their descriptions are omitted.

[0020] Please refer to Figure 1 , Figure 2 As shown, it is a preferred embodiment of the club head with a counterweight block of the present invention, comprising a club head body 1 and at least one counterweight block 2, wherein the at least one counterweight block 2 is combined with the club head body 1.

[0021] The club head body 1 can be made of materials such as magnesium alloy, aluminum alloy, titanium alloy, carbon fiber or glass fiber. The density of the club head body 1 can be 1-5 g / cm3. The club head body 1 can be a wood club head, an iron club head, a wedge club head or a putter head, which is not limited by the present invention. In this embodiment, the club head body 1 is a putter head. The club head body 1 has a ball striking panel portion 11 (face), and the ball striking panel portion 11 is the part of the club head body 1 that contacts the golf ball when hitting the ball. In addition, the club head body 1 can also have a toe portion 12 (toe) and a heel portion 13 (heel), and the toe portion 12 and the heel portion 13 are respectively adjacent to the two ends of the ball striking panel portion 11.

[0022] The club head body 1 may have at least one coupling groove 14, and the at least one coupling groove 14 may be provided for the installation of the at least one counterweight 2. Moreover, the number of the coupling grooves 14 may be equal to or greater than the number of the counterweight 2, so that the user may install a predetermined number of counterweights 2 as required. The at least one coupling groove 14 may be covered in the club head body 1, or the at least one coupling groove 14 may be located on the surface of the club head body 1, which is not limited by the present invention.

[0023] The at least one counterweight 2 is combined with the at least one combination slot 14, so that the club head body 1 has better hitting stability, hitting performance and hitting controllability. Specifically, after the at least one counterweight 2 is combined with the combination slot 14, the total weight of the at least one counterweight 2 can be 40-85% of the total weight of the club head (that is, the total weight of the club head body 1 and the at least one counterweight 2). For example, when the total weight of the club head is 320-380 g, the total weight of the at least one counterweight 2 can be 128-323 g. In one embodiment, the club head body 1 is made of magnesium alloy, and the total weight of the at least one counterweight 2 can be 80-85% of the total weight of the club head. In another embodiment, the club head body 1 is made of aluminum alloy, and the total weight of the at least one counterweight 2 can be 65-70% of the total weight of the club head. In another embodiment, the club head body 1 is made of titanium alloy, and the total weight of the at least one counterweight 2 can be 40-50% of the total weight of the club head. In this way, the at least one counterweight 2 has a better weight adjustment range and can meet the needs of users. In this embodiment, the at least one counterweight 2 can be made of tungsten-iron-nickel, tungsten-copper-nickel or tungsten-nickel, so that the density of the at least one counterweight 2 is 7.5-19 g / cm3. In addition, when the club head body 1 is a putter head, the total weight of the at least one counterweight 2 can be greater than the weight of the club head body 1, so that the ball can be pushed more stably.

[0024] Please continue to refer to Figure 1 , Figure 2As shown, the at least one counterweight 2 can be combined with the club head body 1 in a geometrically symmetrical distribution, so that a center of gravity O of the club head with the counterweight can be roughly located in the center, and will not be too biased to a single side of the club head, so that the club head with the counterweight can have better controllability. For example, the at least one counterweight 2 can be two, and the two counterweights 2 are respectively adjacent to the toe 12 and the heel 13 at both ends of the hitting panel part 11, so that the hitting panel part 11 can form a larger sweet spot. It is worth noting that the club head body 1 has a handle 15, and the handle 15 has a handle center line L. According to the setting position of the at least one counterweight 2, the vertical distance D1 between the center of gravity O and the center line of the handle L is 35 to 55 mm. In addition, the average distance between each counterweight 2 and the center of gravity O is preferably 3 to 7 cm. In this way, when the hitter hits the ball with the club head, a larger moment of inertia (MOI) can be generated. Through the setting of the at least one counterweight 2, the moment of inertia (MOI) on the Z axis (that is, the plane where the club head contacts the ground is regarded as the XY plane and the Z axis extends upward) can be 5800 to 8000 g・cm2, so that the trajectory of the ball can be corrected and better hitting stability can be achieved. Furthermore, the at least one counterweight 2 can be adjacent to a back 16 of the club head body 1, so that the vertical distance between the at least one counterweight 2 and the ball striking panel portion 11 can be 60 to 90 mm, so that the at least one counterweight 2 can be relatively far away from the center of gravity O, so as to further increase the moment of inertia of the club head when hitting the ball. In addition, a vertical distance D2 from the center of gravity O to the ball striking panel portion 11 of the club head body 1 is 12 to 55 mm, so that the center of gravity O can form a better center of gravity depth relative to the ball striking panel portion 11, which can reduce the back-spin of the ball and increase the flying distance when hitting the ball.

[0025] In summary, the club head with a counterweight block of the present invention, after the at least one counterweight block is set on the club head body, forms a predetermined vertical distance between the center of gravity of the club head with a counterweight block and the center line of the handle of the club head body, and a predetermined vertical distance between the center of gravity and the hitting panel of the club head body. In this way, the moment of inertia of the club head when hitting the ball can be further increased, and the back spin force when hitting the ball can be reduced, so as to achieve better hitting stability and controllability.

[0026] Although the present invention has been disclosed using the above-mentioned preferred embodiments, they are not intended to limit the present invention. Any person skilled in the art may make various changes and modifications to the above-mentioned embodiments without departing from the spirit and scope of the present invention. These changes and modifications still fall within the technical scope protected by the present invention. Therefore, the protection scope of the present invention shall include all changes within the meaning and equivalent scope of the appended claims.
