Description

Technical Field

[0001] This application relates to the field of sports equipment, specifically to an adjustable golf wood head and wood. Background Technology

[0002] A golf clubhead consists of a neck, face, cap, and sole. Golf clubs are divided into irons and woods. Golf irons are lightweight and relatively small, with thinner heads and shafts; while golf woods have thicker shafts and larger heads. The face of a wood is generally made of a highly elastic alloy material, and the clubhead has a hollow cavity. Irons have a greater curve on fairways than woods, and the degree of curve also differs. Irons have a certain weight, making them suitable for use on relatively flat fairways. Woods, although lighter, have less curve on fairways and higher speeds, making them suitable for drives and longer distances. Therefore, the primary function of woods is to hit long balls, requiring the clubhead structure and materials to have a certain degree of rebound (COR: coefficient of rebound, or CT value). Currently, most golf wood heads are pre-made, available in different sizes, with fixed weight, center of gravity, and elasticity, offering limited adjustability.

[0003] In the process of customizing golf drivers, different center of gravity positions, weights, and face elasticities need to be customized for users based on their technical preferences and other factors. Therefore, how to conveniently and quickly adjust the center of gravity position, weight, and face elasticity of the driver head to obtain the driver head configuration parameters that meet the user's needs has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0004] In view of the above problems, this application provides an adjustable golf wood head and wood to solve the technical problem that the center of gravity and elasticity of the golf club are not easy to adjust.

[0005] To achieve the above objectives, this application provides an adjustable golf wood head, comprising:

[0006] The base is provided with a handle mounting part, and the handle mounting part is provided with a mounting hole that matches the end of the handle;

[0007] The clubface, located on the front surface of the base, is used to strike the golf ball;

[0008] An adjustment component, disposed on the rear surface of the base, is used to adjust the center of gravity of the rod head and the rebound coefficient of the rod surface. The adjustment component includes a connecting rod, a fixing component, and multiple elastic plates. The bottom end of the connecting rod is movably connected to the middle part of the base, allowing the connecting rod to swing around the bottom end.

[0009] The fixing component is disposed at the top of the connecting rod. The elastic sheet is made of elastic sheet material and is spaced along the outer periphery of the rod surface to provide elastic support force to the rod surface. The first end of each elastic sheet is fixedly connected to the corresponding position of the rod surface, and the second end of each elastic sheet is connected to the fixing component. The connection position of the second end to the fixing component is adjustable, so that the bending arc of each elastic sheet and the elastic support force provided to the rod surface are adjustable.

[0010] Furthermore, the fixing component includes an outer fixing ring, an inner expansion ring, and a central conical nail;

[0011] The inner expansion ring is disposed inside the outer fixing ring, and a plurality of mounting grooves for accommodating the second end are provided circumferentially between the outer wall of the inner expansion ring and the inner wall of the outer fixing ring. An assembly hole is provided in the middle of the inner expansion ring for assembling the central conical nail. The central conical nail is used to press the inner expansion ring outward, so that the inner expansion ring expands outward and locks the second end.

[0012] Furthermore, the outer fixing ring is a counterweight with weight, and the fixing assembly includes two or more outer fixing rings of different weights that can be selected.

[0013] The weight of the rod head can be adjusted by selecting outer fixing rings of different weights, and the center of gravity of the rod head can be adjusted in a first direction and a second direction that are perpendicular to each other by connecting the second end of each elastic piece to the fixing assembly.

[0014] Furthermore, the fixing component is adjustable at the top of the connecting rod along the axial direction of the connecting rod, so that the center of gravity of the rod head is adjustable in a third direction, which is perpendicular to both the first direction and the second direction.

[0015] Furthermore, the outer fixing ring has a regular polygonal hole in the middle, and the inner expansion ring is a regular polygonal block structure corresponding to the regular polygonal hole, formed by multiple movable locking blocks abutting each other end to end.

[0016] Furthermore, the rod face is made of an alloy material.

[0017] Furthermore, the number of elastic pieces is three, four, five, or six.

[0018] Furthermore, the bottom of the connecting rod is connected to the middle of the base via a universal joint.

[0019] Furthermore, the center of the clubface is textured to increase friction with the ball.

[0020] To address the aforementioned technical problems, this application also provides another technical solution:

[0021] A golf wood includes a shaft and a head. The shaft is made of wood, one end of which is a handhold, and the head is located at the other end of the shaft. The head is an adjustable golf wood head as described in any of the above technical solutions.

[0022] Unlike existing technologies, the above-mentioned technical solution separates the clubface from the base and adjusts the clubface's rebound coefficient using an adjustment component. This adjustment component includes a connecting rod, a fixing component, and multiple elastic plates. Each elastic plate has its first end connected to a different position on the outer periphery of the clubface, and its second end connected to the fixing component. The connection positions of these second ends are adjustable, allowing for adjustment of the bending radius and elasticity of each elastic plate, thereby adjusting the clubface's rebound coefficient. Furthermore, by adjusting the connection positions of the second ends of each elastic plate, the connecting rod can swing in different directions, allowing the clubhead's center of gravity to be adjusted in multiple directions.

[0023] The above description of the invention is merely an overview of the technical solution of this application. In order to enable those skilled in the art to better understand the technical solution of this application and to implement it based on the description and drawings, and to make the above-mentioned objectives and other objectives, features and advantages of this application easier to understand, the following description is provided in conjunction with the specific embodiments and drawings of this application.

[0046] Please see Figure 1 This embodiment provides a golf wood, including a shaft and a head. The shaft is made of wood, one end of which is a handhold, and the head is located at the other end of the shaft. The head is an adjustable golf wood head as described in the following embodiments.

[0047] Please see Figures 1 to 5 This embodiment describes an adjustable golf wood head. For example... Figure 1 and Figure 2 As shown, the adjustable golf wood head includes: a base 2, a face 1, and an adjustment assembly 3.

[0048] The base 2 is provided with a handle mounting part 21, which has a mounting hole adapted to the end of the handle 200. The clubface 1 is disposed on the front surface of the base 2 for impacting the golf ball. The clubface 1 is not fixed to the base 2; it can be a plate-like structure of a certain thickness made of titanium alloy or other highly elastic alloy. The clubface 1 is stacked on the front surface of the base 2, and positioning pins and holes are provided between the clubface 1 and the front surface of the base 2 to prevent the clubface 1 from sliding parallel to the base 2. To increase the friction between the clubface 1 and the ball, and to generate more spin on the ball upon impact, the middle of the clubface 1 is provided with texture 11 to increase friction with the ball.

[0049] An adjustment component 3 is disposed on the rear surface of the base 2 and is used to adjust the center of gravity of the rod head and the rebound coefficient of the rod surface 1. The adjustment component 3 includes a connecting rod 32, a fixing component 33, and multiple elastic plates 31. The number of elastic plates 31 can be three, four, five, six, or even more. This application does not limit the specific number of elastic plates 31.

[0050] The bottom end of the connecting rod 32 is movably connected to the middle of the base 2, allowing the connecting rod 32 to swing around its bottom end. Figure 5 As shown, the bottom of the connecting rod 32 is connected to the middle of the base 2 through a universal ball joint 321. The bottom of the connecting rod 32 can swing around the universal ball joint 321 at any position in the circumferential direction indicated by arrow W (that is, the connecting rod 32 can be adjusted in the first and second directions that are perpendicular to each other).

[0051] The fixing component 33 is disposed on the top of the connecting rod 32. The elastic sheet 31 is made of elastic sheet material and is spaced along the outer periphery of the rod surface 1 to provide elastic support force to the rod surface 1. The first end of each elastic sheet 31 is fixedly connected to the corresponding position of the rod surface 1, and the second end of each elastic sheet 31 is connected to the fixing component 33. The connection position of the second end to the fixing component 33 is adjustable, so that the bending arc of each elastic sheet 31 and the elastic support force provided to the rod surface 1 are adjustable.

[0052] In existing technologies, common wood clubheads are welded from sheet materials such as the club cap, resulting in limited rebound performance and low adjustability. In this embodiment, however, the elastic plate 31 enhances the clubhead's rebound coefficient, allowing for greater hitting distance.

[0053] The fixing component 33 can lock the second ends of several elastic pieces 31 (the second ends of the elastic pieces 31 are locked to the counterweight).

[0054] like Figure 3 and Figure 4 As shown, the fixing component 33 includes an outer fixing ring 331, an inner expansion ring 332, and a central conical pin 333. The outer fixing ring 331, the inner expansion ring 332, and the central conical pin 333 are all made of metal or alloy materials. The outer fixing ring 331 has a hollow center. The inner expansion ring 332 is disposed within the outer fixing ring 331, and multiple mounting grooves 334 for accommodating the second end are circumferentially arranged between the outer wall of the inner expansion ring 332 and the inner wall of the outer fixing ring 331. An assembly hole 335 is provided in the center of the inner expansion ring 332 for assembling the central conical pin 333. The central conical pin 333 is used to press the inner expansion ring 332 outward, causing the inner expansion ring 332 to expand outward and lock the second end.

[0055] The outer fixing ring 331 is a counterweight with weight, and the fixing assembly 33 includes two or more outer fixing rings 331 of different weights that can be selected; by selecting outer fixing rings 331 of different weights, the weight of the club head can be adjusted, and by adjusting the connection position between the second end of each elastic piece 31 and the fixing assembly 33, the center of gravity of the club head can be adjusted in a first direction and a second direction that are perpendicular to each other. Figure 2 As shown, the first direction and the second direction can be up and down and left and right.

[0056] The fixing component 33 is adjustable at the top of the connecting rod 32 along the axial direction of the connecting rod 32, making the center of gravity of the rod head adjustable in a third direction, which is perpendicular to both the first and second directions. Figure 2 As shown, the third direction can be the front-to-back direction. Specifically, the outer fixing ring 331 of the fixing component 33 can be threadedly connected to the connecting rod 32 to adjust the axial position. The center of the outer fixing ring 331 is a regular polygonal hole, and the inner expansion ring 332 is a regular polygonal block structure corresponding to the regular polygonal hole, formed by multiple movable locking blocks 3321 abutting end-to-end.

[0057] Indicatively, the outer fixing ring 331 has a regular hexagonal hole in the middle, and the inner expansion ring 332 has a regular hexagonal structure. There are six mounting grooves 334 between the outer fixing ring 331 and the inner expansion ring 332, so at least six elastic pieces 31 can be installed.

[0058] The following explanation uses four elastic plates 31 as an example. The four elastic plates 31 are evenly distributed along the outer periphery of the rod surface 1, and the positions of the four elastic plates 31 correspond to the top, bottom, front, and back of the rod surface 1.

[0059] By adjusting the connection position of the second end of the different elastic plates 31 (up, down, front, back), the length from the first end of the elastic plate 31 to the connection position can be adjusted, thereby allowing the connecting rod 32 to swing in different directions and achieving the purpose of adjusting the center of gravity of the rod head.

[0060] Adjusting the clubhead's center of gravity in the vertical direction can affect the ball's launch angle and trajectory.

[0061] When adjusting the clubhead's center of gravity in the forward and backward direction (away from or near the neck), it can affect the direction of the ball's trajectory on the horizontal plane, commonly referred to as veering left or right.

[0062] Adjusting the clubhead's position (left for closer to the clubface, right for further away) can affect its moment of inertia (MOI), which in turn affects its forgiveness. The further to the right the clubhead's center of gravity is, the greater its MOI and the higher its forgiveness.

[0063] Furthermore, since the fixed component 33 has counterweights of different weights (i.e., the outer fixed ring 331), adjusting different counterweights can adjust the weight of the clubhead, thereby affecting the effect when hitting the ball.

[0064] When customizing golf clubs, the position of the clubhead's center of gravity can be easily and flexibly adjusted up and down, forward and backward, and left and right. It can also be used as a teaching tool to help players understand the principles of hitting the ball. The structural design with the elastic plate 31 makes the clubhead more responsive and the ball travels further.

[0065] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
