Club for park golf {CLUB FOT PARK GOLF}

The present invention relates to a club for park golf, and more particularly, by improving the head constituting the club to attenuate the impact and vibration generated in the process of hitting the ball to improve the hitting feel while improving the flying distance and enabling correct aiming. It relates to the provision of improved clubs for park golf.

Park Golf started in 1984 in Hokkaido, Japan, and a ball with a diameter of 6 cm filled with synthetic resin is made of wood, 86 cm in length and 600 g in weight, using only one club from the starting point (tee-off) toward the hole. It is a form in which the person who hits the ball and turns the course in turn, the person who puts the ball into the hole with the fewest strokes until the final course, wins.

The club used in park golf as described above is composed of a head having a face capable of attacking, and a shaft coupled to the head and having a grip on the upper end. Looking at such a club for park golf through patent literature, it is as follows.

Patent Document 1 is a park golf comprising a face portion formed on the front portion while striking a golf ball, a crown portion at the upper end and a side portion formed integrally, a soul portion formed at the lower end and a hosel portion connected to the shaft For the club head,

The park golf club head has an inner core made of wood, and the range of impact is increased as the face portion can be formed wide by reducing the total weight of the club head, and as it absorbs impact energy caused by hitting the golf ball, the user It characterized in that it comprises an absorbent member laminated on the inner core to reduce the amount of impact transmitted to the body.

Patent Document 2 is a polyol (polyol) 100 parts by weight; 100 parts by weight of isocyanate (lsocyanate); 0.2 to 0.8 parts by weight of catalyst; 0.5 to 1.5 parts by weight of a foam stabilizer; And 0.05 to 0.5 parts by weight of a blowing agent; Provide a park golf club head composition containing,

Patent No. 10-0890057-0000 Patent No. 10-1851622-0000

None.

Patent Document 1 includes an absorbent member on the outer surface of the inner core constituting the head to increase the volume of the head to increase the hitting range, and to reduce the impact generated during the attacking process, Patent Document 2 Is intended to allow the head to be made of a polyurethane resin composed of polyol, isocyanate, and catalyst.

In the case of Patent Document 1, an absorbent member is laminated or coated on the outer surface of the inner core made of wood, but in practice, such a golf club is not used, and in the case of Patent Document 2, the head is made of wood. It violates what is prescribed to consist of.

Apart from these, the configuration of a generally used park golf club is as follows.

In a typical park golf club (1), a shaft (3) made of carbon (graphite) is connected to an upper portion of a head (2) made of wood, and a grip that a user can hold at the upper end of the shaft (3) Combine (4).

The head (2) is configured to form a soul (5) that can be in contact with the ground or mat on the bottom, a crown (6) on the top, and a flat face (7) on the front to directly hit the ball to be.

Recently, as a means for increasing the flying distance by increasing the anti-reaction force on the surface of the face 7, it is configured by fixing a plate 8 made of a car phone or glass fiber having a predetermined thickness.

In the case of a park golf club to which the prior art as described above is applied, it is possible to increase the flying distance to some extent by the plate fixed to the face, but since the hitting feeling is too hard, the impact of the user's wrist and arm whenever the ball is hit. Since over-vibration is transmitted as it is, it has a bad effect.

Due to the nature of the park golf club, the face is formed at a right angle to the head and remains flat, so it is difficult to properly hit the ball when hitting because the head is in the form of covering the ball at address for hitting. There is the same psychological pressure, and it is difficult to fit into the sweet spot because it also appears in the actual blow.

In this way, due to the difficulty of hitting and the ball is mismatched with the pace, the shock and vibration become larger and the torsion of the club becomes severe, which accelerates the physical damage and abnormality of users and causes an increase in the elbow phenomenon of wrist abnormalities. Becomes.

The overall weight balance between the head and the shaft does not match, so when the club is lifted, it feels heavy. Therefore, if the swing is not stable and the balance of the club cannot be maintained stably, the club is trying to escape during the swing process. Since the centrifugal force to rotate the club becomes larger than the existing centripetal force, the head moves unnecessarily in advance, so it does not make an accurate impact and does not escape from the casting phenomenon or scooping phenomenon caused by the headpost. It consists of hitting the top of the ball, including hooks and malicious slices.

Or, if the head is excessively heavy or the shaft is too heavy to maintain a stable balance, the shaft is shaken severely during the swing process, which makes it difficult to accurately hit the ball.

And, even in the process of taking an address posture for hitting, the ball always comes into the eye before the swing, so the user's head is inclined in the direction of the ball, and eventually the shoulder is open, and even if the user swings the right way, the ball is in the desired direction. There are various problems, such as the occurrence of an aiming defect that flies in a different direction.

Accordingly, in the present invention, as invented to solve the above problems, a shaft 103 connected with a grip 102 on an upper portion of the head 101 made of wood, and a bottom surface of the head 101 In the park golf club 100 comprising a soul 104 to be formed, a crown 105 to be formed on an upper surface, and a face 108 to which a flat plate 106 is fixed to hit the ball on the front surface;

A reaction force means (110) for increasing the flying distance while improving the feel of hitting by making it inside the face (108);

A marker 130 provided on the crown 105 to enable correct aiming and smooth swing;

It further comprises a weight body 150 built in the shaft 103 to maintain a balance of centrifugal force and centripetal force to hold the flow of the head 101 and the shaft to enable a stable swing;

It enables stable swing by increasing centripetal force while minimizing torsion and flow while minimizing the reaction force, and protecting the user's body by absorbing the shock and vibration generated during the hitting process while increasing the flying distance through accurate hitting on the sweet spot. It is possible to achieve a certain purpose.

The present invention is designed to increase the anti-reaction force when hitting the ball while mitigating the impact and vibration inside the face of the head of the park golf club, thereby preventing physical damage to users, while increasing the distance and improving the hitting sound. It has the effect that can increase the taste of the hand commonly talked about by good.

The present invention minimizes blocking of the ball when taking an address to strike the ball, thereby reducing the hitting burden, further devising a marker that can maintain the aiming and address posture stable and correct on the crown of the head, and adding or subtracting the head weight. The user's convenience can be increased by allowing the user to respond by changing the weight of the entire club according to the user's body.

In the present invention, a weight body is built inside the shaft, and the overall balance is maintained with the weight body provided in the crown of the head, so that the weight of the club is lightened and the centripetal force is increased so that the player swings the golf club. The head speed is increased while maintaining a stable swing balance by maintaining a stable swing balance through the system and reducing the shaking of the head during downswing. As a result, it is possible to easily hit the ball on the sweet spot of the head face. It is an invention that has various effects, such as increasing the flying distance and improving the directionality and catching the flow of the shaft and the head, thereby enabling a stable swing.

In a conventional park golf club 100, a shaft 103 having a grip 102 that can be held by a user is connected to an upper portion of the head 101 made of wood, and the bottom surface of the head 101 A soul 104 that can be in contact with the ground or mat is formed, has a crown 105 on the upper surface, and has a face 108 in which a flat plate 106 is fixed to directly hit the ball on the front surface.

In the present invention, a reaction force unit 110 is provided inside the face 108 to increase the flying distance while improving the feel of hitting, absorbing shocks and vibrations generated during the hitting process, helping the user's body safety, and A marker 130 is further provided in 105) to enable a smooth swing while enabling correct aiming, and a weight body 150 is incorporated in the shaft 103 to maintain a balance between centrifugal force and centripetal force, and the head 101 It is characterized in that a stable swing is possible while holding the flow of the and shaft.

The reaction force means 110 forms a plate reaction force groove 111 to be concave in the inner surface of the plate 106 fixed to the front surface of the head 101 or the plate reaction force groove 111 formed in the plate 106 It is configured in a form in which only the head reaction groove 112 is formed in the head 101 at the corresponding position, or the plate reaction groove 111 and the head reaction groove 112 are simultaneously formed.

It is obvious that the plate reaction groove 111 and the head reaction groove 112 are located in the sweet spot area as shown in FIG. 2, and a fixing means such as a screw for fixing the plate 106 and the head 101 You may form in this unobstructed range.

As another example, as shown in Figs. 3 and 4, the size of the plate reaction groove 111 and the hand reaction force groove 112 is expanded to cover the entire area excluding the face 108 of the head 101 and the edge of the plate 106. It would be okay to form over and increase the reaction force.

In particular, since the depth (D) of the plate reaction groove 111 formed in the plate 106 is such that the plate 106 is not damaged or deformed even when the ball is frequently hit, the thickness of the plate 106 (T) It is preferable not to exceed 2/3 of the depth, and the depth (D1) of the head reaction groove 112 may be deeper than the depth (D) of the plate reaction groove 111, so there is no limitation, but processing is unnecessarily deepened. There is no need to make it difficult.

This means that when the thickness of the plate 106 is reduced by the plate reaction groove 111, the reaction force may be good, but the durability of the plate 106 becomes weak, and when the depth of the plate reaction groove 111 is thin, the plate 106 ) Is thick, so durability can be maintained, but there may be a phenomenon that does not help with reaction force.

The plate reaction force groove 111 and the head reaction force groove 112 may be equipped with a reaction force pad 113 so as to maximize the reaction force of the plate 106 when hitting the ball to increase the flying distance.

The reaction pad 113 is composed of a rubber material having a size that can be inserted into the reaction groove or plate reaction groove 111 and the head reaction groove 112, or absorbs shock and vibration while having excellent reaction force such as urethane or silicone. It may be made of a material that can be inserted and inserted.

The reaction pad 113 may be built in a flat shape, but it may be configured in a shape having an uneven groove or a hollow portion of a honeycomb shape to increase the reaction force while increasing the absorption of shock and vibration.

As another example of the reaction pad 113, a thin metal or non-ferrous metal plate having excellent elasticity may be interposed between the head 101 and the plate 106 to absorb shock and vibration as well as repulsive force.

A chamfer 115 is performed at the junction of the crown 105 and the face 108 so that the ball is large and large when addressed for hitting, giving the recognition that it is easy to hit, and making it easy to fit into the sweet spot as well as the ease of hitting. .

In addition, in view of the fact that it is difficult to hit the ball because the volume of the head 101 cannot be increased by the regulation that the weight of the head 101 does not exceed 380 g, the crown 105 in the direction of the soul 104 of the head 101 One or more hollow parts 120 are formed in the direction, and the hollow part 120 is filled with a core material 121 made of a light and strong carbon-like material to be fixed. ) It may be configured to increase the volume without increasing the weight of the head 101 while preventing damage from breaking and to make it easier to hit the ball.

The marker 130 may attach a mark 131 that can be visually identified by a user anywhere on the surface of the crown 105 of the head 101, but preferably, most of the markers are covered by the shaft 103 at the time of addressing. It is good to put it in a position where a part is exposed to the right side of (103) because the head does not go forward at address and prevents the left shoulder from opening while looking at the mark 131, so that both shoulders become parallel to induce correct aiming.

The mark 131 will be able to have a variety of shapes and shapes, such as a circle, a triangle, and a character, and may be variously performed, such as printing on the crown 105 or forming a groove, so that any one shape and It is not specified in shape, and may be simply attached to the surface of the crown 105, as well as securely fixed using well-known fixing means so as not to be easily separated or separated.

As another example of the mark 131, a sphere. It is provided with a marking body 132 of various shapes such as a hexahedron or a character, and the coupling protrusion 134 formed with the marking body 132, the male screw 133 is integrally formed, and the female screw ( 135) to be coupled to the formed defect groove 136 and to be able to be separated.

In the case of the marked body 132, a number of different weights are provided to provide an appropriate weight in response to the user's body shape or condition, the weight of the head 101 or shaft 103, and the weather conditions on the day of park golf. You just need to exchange it for a branch so that you can maintain the balance.

The weight body 150 maintains the weight balance between the head 101 and the shaft 103 while increasing the centripetal force of the shaft 103, without increasing the total weight of the golf club. (103) or the weight of the grip 102 is made to have a weight equal to the difference that occurs while increasing the weight of the grip 102 so as to be positioned at the inner diameter of the shaft 103 and securely fixed so as not to flow.

The weight body 150 may be made of various materials such as metal, non-ferrous metal, graphite (carbon), synthetic resin, wood, etc., and the shape of the weight body 150 is inserted into the inner diameter of the shaft 103, so that the tip end portion It is preferable to have a truncated cone shape with a small diameter in the direction and a large diameter in the butt end direction, and the length and weight may vary according to the weight of the head 101 and the grip 102, the shaft 103 and the marker 130. There will be.

It is natural that the fixed position of the weight body 150 may be varied in consideration of fitting while facilitating head balance without being fixed to any one of the inner diameter portions of the shaft 103, and the head 101 and When assembling the shaft 103, it is preferable to form a hole or groove in the center or edge of the weight body 150 so that air can be discharged.

Looking at the state of use of the park golf club 100 to which the technology of the present invention is applied as described above is as follows.

After placing the ball in the tee box, the user takes an address after aiming the hitting direction, strikes the ball through a swing, moves to the hole, and finally puts the ball into the hole to calculate the number of strokes and play the game with the score generated. It is a well-known fact.

In this process, as well as increasing the flying distance of the ball by the reaction force means 110, it is possible to minimize the conduction to the user's body by absorbing the shock and vibration generated in the process of hitting the ball.

Looking at this, a plate reaction groove 111 is formed in the plate 106 fixed in front of the head 101, and the head reaction groove 112 is formed in the head 101 at a position corresponding to the plate reaction groove 111. Or, by forming the plate reaction groove 111 and the head reaction groove 112 at the same time to give elasticity to the plate 106 so that the flying distance can be increased when hitting the ball, the plate reaction groove 111 and the head Since the shock and vibration generated when hitting the ball through the space of the reaction force groove 112 are alleviated or canceled, it is possible to perform a buffer function as well as increase reaction force.

In addition, even when the reaction pad 113 is further interposed in the plate reaction groove 111 and the head reaction groove 112, the reaction pad 113 has elasticity, so when the ball is hit, the distance is increased by the reaction force. The reaction force pad 113 absorbs the shock and vibration to mitigate and cancel it, thereby minimizing the conduction of the user's body.

And, when taking the address posture to hit the ball by chamfering the upper surface of the plate 106, the head 101 minimizes covering the ball to make the ball appear larger, so that the user easily hits the ball that appears psychologically large. It has the effect of being able to do it.

The volume of the head 101 is increased by the reduced weight while reducing the weight of the head 101 through one or more hollow portions 120 formed in the direction of the crown 105 in the soul 104 constituting the head 101. It becomes possible to facilitate the blow of.

It is easy to hit the ball with the volume of the enlarged head 101, but the core material in the hollow part 120 to be damaged by the shock and vibration generated when hitting the ball by the hollow part 120 By filling and fixing (121), durability is increased and prevented, and on the contrary, a double effect of absorbing shock and vibration can be obtained.

At the same time, since the marker 130 further provided on the header 101 induces the swing motion to be stably performed, the ball can be hit to the sweet spot through the correct swing.

This is because the mark 131 constituting the marker 130 is partially covered by the shaft 103 and partially exposed to the right side of the shaft 103 when viewed from the user's gaze at the address. 131), so the user's shoulders naturally become parallel with both shoulders, so that the shoulders of the user are naturally aimed or maintained properly, and the shoulders are closed to prevent being made in the open state during the backswing and downswing process. will be.

When the mark 131 is configured to be disassembled and coupled to the crown 105 of the head 101, the weight is changed according to the weather conditions such as the user's physical condition or wind, the conditions of the site, and the condition of the club 100. Since it is replaced and used, it is possible to maintain a swing balance as well as a function as a marker or to perform a fitting function of the club 100.

When the mark 131 is provided in a spherical shape, the user swings carefully or gently and slowly so that the mark 131 does not fall from the head 101 during the swing process, a problem that may be caused by a fast swing. You will be able to dissolve them.

And, since the weight body 150 is built into the shaft 103, the weight of the weight body 150 is increased or decreased according to the weight of the head 101 and the marker 130, or the weight of the entire club 100 is reduced. While being lightweight, the weight body 150 as much as the weight may be built-in so as not to change the weight of the entire club 100.

When the weight body 150 is embedded in the shaft 103 as described above, the weight concentrated on the head 101 is distributed to the shaft 103, so that the weight of the club 100 is felt lightly. It can be easily made to control.

In addition, since the weight body 150 is built into the shaft 103 to increase the centripetal force at the position of the grip 102, the user can easily pull the club down when performing a swing, so that the hand first is naturally made and the head follows. Headlast is realized.

Since the built-in weight 150 of the shaft 103 catches the shaking or flow of the shaft 103 and the head during the swing process and minimizes torsional torque, a stable swing is enabled and the space surface of the head at the moment of impact Since it helps the ball to be hit accurately, the distance is increased with the hitting.

During the swing process, the weight 150 interposed on the shaft 103 until the moment of impact increases the centripetal force, so the user's hand, which is the grip 102 part, is pulled first rather than the head 101, followed by the head 101 After the following Hand First, it becomes a normal swing with an impact through the Head Last, so casting or scooping can be eliminated.

Since the head follows by the hand first, the head speed naturally increases, so the distance of the ball after the impact increases, and the torsion torque and flow of the shaft 103 are caught by the double weight body, and the impact on the sweet spot becomes possible. will be.

The present invention as described above enables stable swing by increasing centripetal force while minimizing torsion and flow while improving reaction force, and absorbing shocks and vibrations generated during the hitting process while increasing the flying distance through accurate hitting to the sweet spot. It has advantages such as being able to protect its body.
