Description

  The present invention relates to golf club heads, and more particularly, to the center of gravity of each golf club head according to various effects required by golf players for wood-shaped clubs such as driver heads, fairway wood heads, utility heads, etc. The golf player can easily adjust and adjust the weight adjustment screw that places the most importance on the center of gravity position setting to the sole part and body of the wood club head, such as position, center of gravity height difference, head weight, and balance required for the club. On the other hand, if the golfer can match optimally and has a certain level of hitting technology, the ball muscle as intended by attaching the weight adjustment screw to the sole part of the club head with a simple operation, as intended by the professional. As well as shaft characteristics It can embody the pitch to effect the present invention relates to golf club head to achieve the intended player.

  In general, many golf clubs on the market are models that focus on how easily it is possible to obtain the maximum flight distance straight, assuming an average amateur golfer. Most of them are deep, have a lower center of gravity, and are more oriented. It is an important task to fly a hit ball in golf play to a precisely aimed point. It is known that the flight characteristics of a ball are closely related to the spin amount, compression load, rotation direction, and the like of a hit golf ball. In order to correct these, the golf player manipulated the hand gripping the shaft, and controlled the spin amount, compression load and rotation direction of the golf ball by rotating the body and moving the weight, and hit. The ball is made to fly to the target point.

  However, for advanced players or general golf players other than professional golfers, it is extremely difficult to finely control the spin rate, compression load, and direction of rotation of the golf ball, which is extremely difficult. It is difficult to hit accurately. The sweet spot is generally defined as an area or a point on the hitting face that is located on a line perpendicular to the hitting face passing through the center of gravity of the head.

  Considering these points, especially for beginner and intermediate golf players, the flying performance of the golf ball greatly affects the position of the center of gravity of the club head, the height of the center of gravity, the weight, the balance, and the impact load applied to the golf ball. It is known that the difference in height of the center of gravity has a close relationship with the angle (elevation angle) at which the golf ball is launched, and when the center of gravity is increased, the launch angle of the golf ball is lowered. And the product which can mount | wear with the adjustment member devised so that the gravity center position and weight distribution of several wood-shaped golf club heads may differ is provided.

  Furthermore, as is well known, a golf club head having a metal material wood-shaped main body can hardly change the weight distribution of the head main body after molding, for example, even if the weight distribution is changed, it is about 10 g. The adjustment lead sheet within 15 g is pasted on the head body to change the swing balance. And this heavy weight sheet has an adhesive layer formed on the back side of the thick lead tape, and it is attached to the outer surface of the headpiece using the adhesive strength of the adhesive layer after cutting it to the required size (weight) I have to do it. However, if such a heavy sheet is attached to the outer surface of the head piece, especially the sole surface that contacts or rubs against the ground surface when hit, the heavy sheet will peel off or the bonding position will shift due to strong contact or a decrease in the adhesive strength of the adhesive layer. As a result, the weight balance adjusted was out of order, or adjustment was impossible.

  In addition, the weight sheet is generally attached to a sole portion and a peripheral side surface excluding the face surface of the club head. Therefore, from the viewpoint of increasing the head speed at the time of hitting the ball by the centrifugal force of the club and extending the flight distance of the ball, it is desirable that the club head has a low center of gravity. When it is attached to the peripheral side surface, the club head deteriorates the hitting function because the center of gravity rises.

In contrast to the above-described technology, this device can be equipped with several insert weight adjusting members on the sole portion of the main body of the golf club head, and can be equipped with weight screw members of different weights and materials. It was developed in such a way that it can be selected and mounted in combination, fixed, and the position of the center of gravity, height difference and weight, distribution, balance, etc. can be adjusted arbitrarily easily.
Even if the golf player's technology is at the beginner's level or intermediate level, the technology is different, and the golf player's club swing trajectory, striking form, club weight and balance, head speed, etc. also have such requirements. It is slightly different depending on the individual. However, it is a fact that conventional technology and performance changing means for golf clubs cannot accurately meet such fine technical requirements.
Therefore, in this device, a golfer having a certain hitting technique can hit the ball as intended by attaching a weight adjusting screw to the sole of the club head with a simple operation, as the ball is intended by a professional. In addition to the shaft characteristics, the hitter's intention can be realized.

  The present invention has been devised in view of the above problems, and a golf club head according to the present invention is a so-called wood-shaped object, and includes at least a striking face, a sole, and a crown. Several different weights for adjusting the center of gravity of the center of gravity to the toe side, heel side, and back side can be mounted in a watertight manner so that they can be exchanged in a watertight manner. The center of gravity of the head body, weight, balance, impact weight, head The speed is adjustable.

That is, in the golf club head according to the present invention, as a means for achieving the above-described object, a clockwise thread portion is engraved in a concave portion integrally formed with the sole member toward the hollow interior of the club head. A weight screw for adjusting the center of gravity with a different weight is attached to the part in a watertight manner through an O-ring packing, so that moisture can enter from the outside into the club head body during use, and can absorb fine dust powder. At the same time, it is possible to prevent loosening of the screw.
The center-of-gravity position adjusting weight screw is formed of a member having a large specific gravity with respect to the club head main body, such as a titanium alloy, a tungsten material, a stainless steel material, various steel materials, a copper alloy, and the like. It is set so that the front part does not protrude from the sole surface, and it is tightened and fixed in a range using a square groove screw carved on the head front part.

The position of the sole front part of the weight screw for adjusting the center of gravity is set on the toe side, heel side, and back side of the sole, and the club performance can be changed and finely corrected by the effect of different weights. As a result, it is possible to obtain a spherical muscle such as a hook, a slice, and a high and low launch angle desired by the player.
In the adjustment of the center of gravity position, which is the club performance, by changing the weight of the center of gravity position adjusting weight screw arbitrarily, the center of gravity depth and the center of gravity position are changed, for example, by setting the center of gravity position to a low center of gravity. The hitting ball is also likely to rise higher.

  The above-described arrangement of the center-of-gravity position adjusting weight screw on the sole surface portion is illustrated and described with respect to the driver head in the embodiments described in the following paragraphs. However, the loft angle of the head face surface is large, for example, fair It can also be applied to multiple clubs with different counts of waywood and utility heads (approximately 15-30 °).

  That is, when a ball is hit by a club, the position on the face surface that can transmit energy to the ball most effectively and efficiently is the point directly below the face surface from the center of gravity position in the head, or It is known to exist in the vicinity. In this device, paying attention to the fact that the driver head has a small loft angle, it is usually set at the geometrical center point of the face surface or slightly at the top part. Waywood and utility heads have a loft angle that increases with club count compared to the driver, so the best striking position on the face surface is larger in front of the head than the center of the face surface. In other words, since the head volume tends to decrease as the club number increases, the hit point position often deviates from the upper end of the face surface. When a club having such a head is used, the ball is hit at a portion below the hitting point position, so that the spin is applied to the ball more than expected and the ball rises too high and the flight distance is lost. There is a problem of lowering the hitting sound.

  In consideration of these problems, the weight screw for adjusting the center of gravity of the present invention is formed of a member having a specific gravity greater than that of the head body, and the best hitting point is obtained at the face surface position where the head center of gravity is directly below the face surface. It is set to the disposition position and weight distribution in the sole part.

  According to the wood-shaped clubs related to this device, such as driver heads, fairway wood heads, utility heads, etc., according to various effects required by golf players, the position of the center of gravity of each golf club head, the difference in center of gravity, the head weight. The weight adjustment screw that emphasizes the center of gravity position setting to the sole part of the wood club head and the body body can be easily mounted and adjusted by the player, making it possible to optimally match with the golf player. If a golfer has a certain level of hitting technology, he can not only hit the ball as intended by attaching a weight adjusting screw to the sole of the club head with a simple operation, but also shaft characteristics. Player who can embody effects that match It is possible to provide a golf club head to achieve the intended of.

It is a perspective view which shows the surface of the sole part of the golf club head concerning this invention. It is a fragmentary sectional view which shows the structure of the weight screw for gravity center position adjustment of the golf club head concerning this invention. In the figure, (A) shows the mounting order of the center-of-gravity position adjusting weight screws, and (B) is a partial cross-sectional view showing the state after mounting of the center-of-gravity position adjusting weight screws.

  In this way, according to the present invention, the ball muscle as intended by the professional can be hit not only as intended by attaching the weight adjusting screw to the sole part of the club head with a simple operation, but also matches the shaft characteristics. Realized the original purpose of embodying the effect.

An example of this invention will be described based on the embodiment shown in FIGS.
A golf club head (1) according to the present invention is a so-called wood-shaped object, and includes at least a striking face (2), a sole (3), and a crown (4), and a toe of the sole (3). Several different weights for adjusting the center of gravity position (W) can be attached to the side part (5), the heel side part (6) and the back side part (7) in a watertight and replaceable manner. The center of gravity, weight, balance, impact weight, and head speed are adjustable.

The golf club head (1) according to each aspect of the present invention is a means for achieving the above-described object, in which the golf club head (1) is clockwise in an interior recessed with the sole member toward the hollow interior (8) of the club head (1). The threaded portion (9) is engraved, and the weight screw (W) for adjusting the center of gravity position of the different weight (specific gravity) is watertightly attached to the threaded portion via the O-ring packing (10). In addition, intrusion of moisture from the outside into the club head body, absorption, and infiltration and relaxation of fine dust powders are also prevented.
This center-of-gravity position adjusting weight screw (W) is selected from a member having a large specific gravity with respect to the club head (1), in this embodiment, a member having a weight of at least 1 g to 10 g. For example, a titanium alloy, a tungsten material, It is made of stainless steel, various steel materials, copper alloys, etc., and when it is attached to the sole (3), the screw head surface portion is set so as not to protrude from the sole surface portion (3a). The square screw groove (11) engraved in the part is used to tighten and fix in the range.

The disposition positions of the center-of-gravity position adjusting weight screw (W) in the sole front portion (3a) are set on the toe side portion (5), the heel side portion (6) and the back side portion (7) of the sole. The club performance can be changed and the fine correction can be made by the effect of different weights, and the ball muscles such as hooks, slices, and high and low launch angles desired by the player can be obtained.
In addition, when adjusting only the center of gravity position, which is club performance, the center of gravity depth and the center of gravity position can be changed by arbitrarily changing the weight of the center of gravity position adjusting weight screw (W), for example, setting the center of gravity position to a low center of gravity. By doing so, the hit ball is also easily raised.

  The arrangement of the center-of-gravity position adjusting weight screw (W) on the sole surface portion (3a) is illustrated and described with respect to the driver head in the embodiment, but the loft angle of the head face surface (2a) is illustrated. For example, it can be applied to a plurality of clubs having different counts such as fairway wood and utility head (approximately 15 to 30 °).

  That is, when a ball is hit with a club, the position on the face surface (2a) that can transmit energy to the ball most effectively and efficiently is perpendicular to the face surface (2a) from the center of gravity position in the head. It is known that it exists at a point directly below or in the vicinity thereof. In this device, paying attention to the point where the driver head has a small loft angle, it is usually set to the geometrical center point of the face surface (2a) or slightly to the top part. Since fairway wood and utility heads have a loft angle that increases corresponding to the club number compared to the driver, the best spot position on the face surface (2a) is higher than the center of the face surface (2a). The hit point position deviates from the upper end of the face surface (2a) because the head volume tends to decrease as the club number increases, and the head volume tends to decrease as the club number increases. Many things happened. When a club having such a head is used, the ball is hit at a portion below the hitting point position, so that the spin is applied to the ball more than expected and the ball rises too high and the flight distance is lost. There is a problem of lowering the hitting sound.

  Considering these problems, the center-of-gravity position adjusting weight screw (W) of the present invention is formed of a member having a specific gravity larger than that of the main body of the club head (1), and the head center of gravity is perpendicular to the face surface (2a). The position of the best hitting point in the sole portion and the weight distribution are set at the face surface (2a) position directly below.

With the above-mentioned devised technology, several insert weight adjustment members can be attached to the sole part of the club head body, and different weights and materials of weight screw members can be attached. The center of gravity position, height difference and weight, distribution, balance, etc. can be arbitrarily adjusted with ease.
Therefore, even if the golf player's technology is basic or intermediate level, if a golfer has a certain level of ball hitting technology, a weight adjustment screw can be attached to the sole of the club head with a simple operation using the ball muscle as intended by the professional. In addition to hitting the ball as intended, the hitter's intended effect can be exhibited, which can embody an effect that matches the club characteristics. According to the golf head of the present invention, the golfer himself can adjust the performance of the golf club head suitable for himself, and can be used for all wood clubs represented by drivers, such as fairway head and utility head. It is a useful idea that can be implemented and can be expected to have the best use effect for golfers.
