Description

  The present invention relates to a weight structure of a golf club head capable of absorbing vibration, and in particular, the head main body absorbs aftershock of a hit ball using an elastic air cushion, and further adjusts the overall center of gravity using a weight. It relates to the structure of vibration absorption and weight that can be.

  As shown in FIG. 13, the conventional golf club head vibration absorbing structure includes a head main body 100 and a vibration absorbing material 200. The head body 100 is provided with a face plate 101 and a cavity 102. The face plate 101 is used for hitting a golf ball. The cavity 102 is used to fill the vibration absorbing material 200. The vibration-absorbing material 200 can preferably be selected from materials whose hardness is between shore D 20 and 50, for example selected from polyurethane (PU), foam or rubber. As a result, the vibration absorbing material 200 can appropriately absorb the after-shock generated at the time of hitting the ball, so that the user can have a relatively comfortable feeling of gripping the hand. (For example, refer to Patent Document 1).

Further, a conventional golf club head vibration absorbing structure includes a head body and at least one weight. The weight is connected to the position of the bottom of the head body by using a method such as welding, screwing, and fitting with an interference fit, so that the position of the center of gravity can be adjusted. (For example, see Patent Documents 2, 3, 4, and 5).
US Patent No. 5,290,036 US Patent No. 6,012,990 US Patent No. 6,206,790 US Patent No. 6,524,198 US Patent No. 6,773,360

  In the vibration absorbing structure of the conventional golf club head as described above, when the golf ball starts to contact the face plate 101 in order to improve the accuracy and direction controllability of the hit ball in the dynamic analysis, the face plate 101 Preferably must be subjected to the stress of a small ball and is formed to rapidly compress and deform. On the other hand, when the golf ball tries to move away from the face plate 101, the face plate 101 should preferably recover rapidly from its maximum elastic deformation to its original shape, thereby having a relatively strong repulsive action. A force is formed and fed back to the golf ball, so that the golf ball can be hit to a far distance. However, during the period in which the face plate 101 is continuously elastically deformed, pressure is always generated on the face plate 101, so that the volume is deformed by compressing the vibration absorbing material 200. Further, when elastic deformation starts to occur in the face plate 101, the ability to recover due to elasticity decreases, and the vibration absorbing material 200 is too in contact with the face plate 101, thus affecting the performance of the hit ball. Further, the vibration absorbing material 200 is in excessive contact with the face plate 101 during the time from when the golf club head starts to contact the golf ball to when the golf ball tries to move away from the golf club head. Therefore, the contact time with the golf ball becomes long because it cannot be bent and deformed effectively. As a result, there is a problem that not only the best vibration absorption effect cannot be achieved by the installation of the vibration absorbing material 200, but also the performance of the entire hit ball is greatly lowered.

  In the conventional golf club head vibration absorbing structure as described above, the weight and the head body are not only too low in resistance in the combined structure formed by using the above-described method, but also the vibration absorbing property. There was a problem of getting worse. In addition, in the state where the head body has been subjected to the vibration of the hit ball for a long period of time, the coupling structure between the weight and the head body is likely to crack or loosen. There was a problem that the weights were dropped. Therefore, the vibration absorbing structure of the conventional golf club head as described above must be further improved.

  Embodiments of the present invention will be described below with reference to the drawings.

  Referring to FIG. 1, the weight-absorbing golf club head weight structure according to the first embodiment of the present invention includes a head body 1, at least one elastic air cushion 2, and at least one weight 3. The head main body 1 has an iron-type head structure, and the head main body 1 is provided with a face plate 11, a hosel 12, a cavity 13, and a storage chamber 14 (vibration suppression zone). A face plate 11 can be formed on the front surface of the head body 1 by, for example, welding, hard brazing, fitting, screwing, or integral molding, and the face plate 11 is used for hitting a golf ball. It is done. The hosel 12 is provided on one side of the face plate 11, and the side of the head body 1 that approaches the hosel 12 is referred to as a heel portion, and the side of the head body 1 that is far from the hosel 12 is referred to as a toe portion (toe). The cavity 13 is provided on the back portion of the head body 1 and is formed so as to expose the back surface of the face plate 11, thereby providing a degree of freedom in which the face plate 11 is elastically deformed rearward. The storage chamber 14 is provided so as to be recessed in the bottom or lower half of the back surface of the head main body 1, and the opening of the storage chamber 14 is formed so as to face rearward and communicates forward to the rear surface of the face plate 11. To be formed.

  Referring again to FIG. 1, the elastic air cushion 2 according to the first embodiment of the present invention is provided with a bladder 21, an air chamber 22, and a coupling portion 23. The sac 21 is made of an elastic material. For example, the sac 21 is made of a material such as rubber, polyurethane (PU), thermoplastic-plastic elastomer, or other polymer elastic resin. The specific gravity of the air cushion 2 is formed to be smaller than the specific gravity of the head body 1. The air chamber 22 is formed to be sealed by the bladder 21, and the air chamber 22 can be selected to be isobaric, high pressure, and low pressure relative to the external atmosphere. By forming at least one side opening in the coupling portion 23, it is possible to assemble and couple the weight 3 by providing an assembly space.

  Referring again to FIGS. 1, 2, and 3, the weight 3 of the first embodiment of the present invention can be selected from a metal, an alloy, a plastic, or a foamed material, that is, the specific gravity of the weight 3 depends on usage demands. For example, it can be selected to be larger than, equal to, or smaller than the specific gravity of the head body. At the time of assembly, the weight 3 first inserts the elastic air cushion 2 into the inside of the coupling portion 23 from the opening on one side of the coupling portion 23. Then, the combination of the elastic air cushion 2 and the weight 3 can be fitted again into the housing chamber 14 of the head body 1 and at the same time fixed using an adhesive, or the elasticity of the elastic air cushion 2 itself. The weight 3 can be easily coupled to the inside of the housing chamber 14 of the head body 1 by using the elastic air cushion 2 without using an adhesive.

Since the center-of-gravity position of the entire club head can be adjusted, the moment of inertia and the performance of the hit ball can be increased (or adjusted). When a golf club head is used for hitting a ball, the golf ball goes through the following steps in order. a) Trying to start contacting the face plate 11. b) Maximum elastic deformation occurs in the face plate 11. c) Final separation from the face plate 11. In the stage a), the face plate 11 is elastically deformed rearward, and a pressure is always generated rearward due to the continuous change. Therefore, the elastic air cushion 2 abuts and the volume of the elastic air cushion 2 is continuously increased. It is formed so as to be compressed and deformed. Since the air chamber 22 of the elastic air cushion 2 contains an appropriate amount of gas, the elastic air cushion 2 is immediately subjected to compression deformation due to elasticity, and the elastic air cushion 2 is prevented from excessively contacting the head body 11. Therefore, the stress energy of the hit ball can be maintained, and the time for the golf ball to contact the face plate 11 can be delayed. Therefore, the controllability of the direction in the face plate 11 and the hit ball in step b). Can help increase accuracy. In step c), the volume of the elastic air cushion 2 can be quickly restored to the original volume as the pressure generated on the face plate 11 gradually decreases to zero. After the golf ball is launched, aftershock occurs due to partial hitting stress that is not fed back from the face plate 11 to the golf ball, but is recovered until the elastic air cushion 2 is already tightly attached to the face plate 11. The after vibration can be absorbed effectively and the comfort of gripping the club can be further increased.
