Description

TECHNICAL FIELD

The present invention relates to an elastic rubber-based headpad attached to a head and a head face of a golf club in use, more specifically, the present invention relates to a headpad of a golf club, in which a side spin of a golf ball hit by a head face of a golf club is reduced by increasing a back spin of the golf ball, a strike impact between the head face and the golf ball is reduced when hitting the golf ball, and the headpad is a rubber-based product attached to the head and head face of the golf club by applying adhesive or a separate fixing device, and in which the headpad of the golf club utilizes the gear mesh effect between the golf club head and the golf ball, the inertia law between a billiard ball and a billiard cue in a billiard game, and the principle of a ball spin by a tip attached to an end of the cue.

BACKGROUND ART

The golf is a sport in which a golfer hits a golf ball by using a golf club such that the golf ball gets into a hole cup at a smaller number of strokes. To this end, various golf clubs such as drivers, woods, irons, wedges and putters are used.

Among the golf clubs, the driver and the wood are used to make a long driving distance, and the driver and the wood having the head face angle of about 10.5 degrees are mainly used, in which the main purpose of the driver and the wood is to send the golf ball far away with an accurate hit.

Meanwhile, in the case of irons, various types of irons are used such as No. 1 driving iron, No. 2 mid iron, No. 3 mid mashy, No. 4 mash iron, No. 5 mash, No. 6 spade mashy, No. 7 mashy niblick, No. 8 pitcher, No. 9 niblick, a pitching wedge, and a sand wedge, and these irons have their own distance and trajectory characteristics.

The main purpose of these irons is to approach as close as possible to the hole cup on the green from the fairway. To this end, the golf club heads have various weights and various head face angles so as to be selectively used depending on the situation.

However, in order to settle the golf ball close to the hole cup, it is important to minimize the run after the golf ball is seated on the ground. For this purpose, a horizontal groove is formed on the head face so that the golf ball is subject to a strong back spin when the golf ball is hit, thereby preventing the run as much as possible.

The back spin not only allows the golf ball to be stopped in the vicinity of the drop point, but also helps the golf ball to increase the driving distance by lifting force such as an airplane. For this reason, various related arts have been disclosed in relation to the shape of the horizontal grooves.

In the head face of a conventional golf club head, for example, ‘U’-shape or V′-shape horizontal grooves having a depth of 0.25˜1 mm and a width of 0.5˜1 mm are formed at an interval of less than 2.667 mm as shown in FIG. 1.

In this case, when the golf ball is hit, the golf ball is temporally deformed into a planar shape corresponding to a face surface of the golf head and is subject to a downward rotational force according to the angle of the face surface so that the back spin of the golf ball is increased by jaws of the horizontal grooves.

In order to increase the rotational force of the golf ball by the jaws of the horizontal grooves, the depth (width) of the groove has to be increased. However, in this case, although the rotational force can be increased, there is a disadvantage that the driving direction may be unstable and the golf ball and the groove of the head face are severely worn, so the above method is rarely used. In contrast, if the interval of the grooves is narrow, the rotational force may not be effectively transferred, so a normal shape is provided for desired directionality.

However, such a conventional horizontal groove has a problem that less run occurs due to less rotational force in the case of an iron having a relatively short driving distance and the rotational force is remarkably reduced in the rough.

In addition, when a golfer hits the golf ball using the head face of each golf club head, that is, when 1 to 16/392 (at most 51 to 76) in the surface area of the golf ball makes contact with the head face of each golf club, a face angle is formed in the clockwise and counterclockwise directions about a handle shaft and dimple joints (see reference numeral 7 of FIG. 2, in which reference numeral 6 is a golf ball, and reference numeral 8 is a plurality of concave grooves divided by the dimple joints) of the golf ball when viewed from the top of the head face as shown in FIG. 3 and a lie angle (an angle between the shaft of the golf club and the ground) is formed as the head part is lifted up and down as shown in FIG. 4. In addition, the side spin of the golf ball may be generated due to the angle of sole of the golf club. Due to the side spin of the golf ball, the driving direction of the golf ball may be changed to the left and right (hook & slice), so the golf ball travels in the direction other than the direction intended by the golfer, thereby causing the problem in the safety management of the golf course and resulting in the delay of the golf game.

In the case of a golf club formed of a metal, as shown in FIG. 1, a golf club head 1 is coupled to a shaft 10 at a heel part 11, and the golf club head 1 includes a front head face 2, side surfaces 4 on left and right sides of a toe and a top surface 3 on an upper side.

The head face 2 includes horizontal grooves 5 in the form of slots. In the case of an amateur golfer, a shock generated when the head face 2 erroneously hits the golf ball may be applied to fingers, wrists, elbows, shoulders, etc. of the human body through a shaft 10, so there is a problem that the golfer has to be treated in the hospital. In winter, the above problems frequently occur when the golf ball cooled by the atmospheric temperature makes contact with the head face formed of metal, and in the case of the driver, the wood, and the putter, high frequency metallic noise occurs. In addition, when the golfer hits the golf ball with the golf club formed of metal, the dimple joints of the golf ball may directly come into contact with the head face, so the driving direction of the golf ball may differ from the target direction intended by the golfer and this problem becomes serious in the case the putting.

DETAILED DESCRIPTION OF THE INVENTION

Technical Problem

Therefore, the present invention is suggested to solve the above-mentioned problems, and an object of the present invention is to provide a golf club headpad, in which a side spin of a golf ball hit by the headpad added to the golf club can be reduced by increasing the power of the backspin, the side spin can be induced through the gear mesh effect so that the driving direction of the golf ball can be guided into the target direction intended by the amateur golfer, the strike impact between the head face of the golf club and the golf ball can be reduced so that the shock applied to the human body can be reduced, the back spin of the golf ball can be increased so that the driving distance of the golf ball can be increased, and a sweet zone is displayed on the headpad attached to the head face of the golf club to allow an amateur golfer to easily identify the sweet zone.

Technical Solution

In the conventional golf club head, the head face makes contact with the golf ball, 1 to 16/392 in the surface area of the golf ball makes contact with the head face. However, according to the present invention, the headpad is attached to the head and the head face of the golf club so that the surface area of the golf ball making contact with the head face is increased to 6 to 32/392 (at most 51 to 76), thereby preventing the dimple joints of the golf ball from making direct contact with the head face. In addition, the side spin of the golf ball caused by the face angle, the angle of sole and the lie angle of the golf club is reduced by the gear mesh effect and the increased back spin. The driving distance of the golf ball can be increased due to the elasticity of the headpad and the back spin of the golf ball, the change of driving direction caused by the direct contact between the dimple joints of the golf ball and the head face can be reduced and the amateur golfer can easily to identify the effective hitting surface through the sweet zone marked on the head face of the golf club.

Advantageous Effects of the Invention

The present invention can reduce the side spin of the golf ball by using the elastic rubber-based headpad of the present invention, which is added to the head and the head face of each golf club, can induce the side spin through the gear mesh effect such that the driving direction of the golf ball can be guided into the target direction, can reduce the strike impact between the head face of the golf club and the golf ball, and can increase the driving distance of the golf ball.

According to the present invention, the distance determined by the amateur golfer when hitting the golf ball with the putter face formed of metal may be long or short depending on the hitting time and the outside temperature of the putter face and the golf ball. This problem can be prevented by the elastic headpad of the present invention. In addition, the fluctuation in the driving direction of the golf ball, which is caused by the dimple joints of the golf ball, can be prevented by using the rubber-based headpad of the golf club. Further, in the case of the driver, the wood and the putter, the high-frequency metal noise can be prevented so that the strike impact can be reduced as much as possible in cold winter.

BEST MODE

Mode for Invention

In the present invention, a material for a headpad 50 is a rubber-based material having elasticity and flexibility, and at the same time, has a restoring force so that the surface of the headpad deformed due to the hitting may be immediately recovered after the hitting. The flexibility or elasticity may compensate for the excessive side spin applied to the golf ball when hitting the golf ball and the golf ball may come into contact with an anti-groove of the headpad that protrudes, thereby increasing the back spin. The material for the headpad is not specifically limited, and may include Ethylene Propylidene Rubber (EPR), Copolymer of Ethylene Propylidene Monomer (EPDM), natural rubber, polyurethane, silicone rubber, natural fiber, fiber, or mixed material.

As shown in FIGS. 6 to 9, the present invention includes an elastic face plate 20 bonded to a head and a head face of the golf club or covering the head and the head face of the golf club in use and having a shape corresponding to a head face portion.

The face plate 20 has horizontal anti-grooves 30 protruding from a surface of the face plate 20 at a predetermined interval and vertical anti-grooves 40 formed on both sides of the horizontal anti-grooves 30 at a predetermined vertical interval, thereby forming the headpad 50 of the golf club.

The horizontal anti-grooves 30 and the vertical anti-grooves 40 may be configured such they protrude from the surface of the face plate 20 attached a head face 2 of a golf club head 1 as illustrated in FIG. 8. The headpad 50 of the present invention may be attached to the head face 2 of the golf club head 1 with an adhesive, or may be prepared in the form of a pocket that wraps the entire golf club head 1, but the present invention is not limited thereto.

In order to allow a user to recognize a hitting effective point, a sweet zone having a recognizable color may be added to a hitting point of the headpad.

The horizontal anti-grooves 30 and the vertical anti-grooves 40 of the present invention may be configured such that grooves are formed at regular intervals on the surface of the face plate 20 attached to the head face 2. For example, the horizontal anti-grooves 30 and the vertical anti-grooves 40 may be formed on a putter as shown in FIG. 9, an iron head as shown in FIG. 7, and a driver as shown in FIG. 6. The horizontal anti-grooves 30 may have a U-shape that protrudes, but the present invention is not limited to the shape of the anti-groove.

The material for the rubber-based pad 50 of the present invention may include one or at least two of polyethylene, polypropylene, polyvinylacetate, polyvinyl chloride, silicone, and rubber, but the material is not specifically limited so long as the material has a function of providing basic elasticity.

According to the present invention having the above configuration, the driving distance of the golf ball can be increased by the horizontal anti-grooves 30 having elasticity of the headpad 50 and the back spin of the golf ball, the change in direction (hook & slice) caused by the collision between the head face 2 and the dimple joints 7 of the golf ball can be reduced, and the amateur golfer can easily identify the hitting point through the sweet zone of the headpad 50 attached to the head face 2 of the golf club head 1. In addition, the horizontal anti-grooves 30 may absorb water droplets and the like stuck to the surface of the golf ball through the grasses to prevent slipping when hitting the golf ball, the hitting area with respect to the dimple joints 7 of the golf ball 6 may be increased according to the elasticity and flexibility of the headpad 50, and the back spin of the golf ball 6 may be increased, so that the side spin can be reduced, thereby preventing the hooks and slices of the golf ball and increasing the driving distance of the golf ball.

Meanwhile, the present invention may include the vertical anti-grooves 40 on opposite end portions of the horizontal anti-grooves that protrude. In the case of normal hitting, as shown in FIG. 5, when the hitting direction and the hitting force of the golf club head 1 act as a force Fa, the corresponding golf ball 6 receives force Fa′ so that the golf ball 6 travels in the direction of the solid line. However, at the moment when the amateur golfer hits the golf ball, the golf club head 1 may be twisted in the direction of the force Fc from the direction of the force Fa due to the mistake or unskilled hitting. The above force is transferred to the golf ball 6 as the rotating force by the vector force F11 so that the golf ball 6 also travels while rotating by the vector force F11 due to the gear mesh effect. Therefore, the movement path becomes uncertain depending on the strength of the force and the topography of the land. However, according to the present invention, the contact area with respect to the dimple joints 7 may be increased due to the horizontal anti-grooves 30, and the horizontal anti-grooves 30 may absorb a part of the vector force F11 upon hitting, so that less vector force F11 may act, thereby reducing or preventing the erroneous hitting.

That is, when there is no headpad 50 of the present invention attached to the golf club head 1 in use, the condition that the head face 2 makes contact with the golf ball 6 is 1 to 16/392 based on the surface area of the golf ball. However, when the headpad 50 is attached to the head face 2 as in the present invention, the surface area of the golf ball 6 in contact with the face plate 20 of the headpad 50 at the time of hitting is increased to 6 to 32/392 (at most 51 to 76) because the contact area is increased due to the horizontal anti-grooves 30 of the headpad 50. Therefore, due to the front collision of the dimple joints 7 of the golf ball 6 and the vector force F11 and the vector force F12 generated by the face angle, the angle of sole and the lie angle, the power of side spin of the golf ball 6 may be reduced due to the increase of the back spin caused by the headpad 50 of the present invention so that the corresponding vector force F11 and vector force (F12) of the golf ball 6 may be reduced.

In addition, the side spin of the golf ball 6, which is generated due to the front collision of the dimple joints 7 of the golf ball 6 and the vector force F11 and the vector force F12 generated by the face angle, the angle of sole and the lie angle, can be induced by the gear mesh effect so that the driving direction of the golf ball 6 can be corrected to the target direction.
