Description

  The present invention relates to a golf club head structure capable of adjusting vibration absorption, and more particularly to a vibration absorption structure capable of adjusting the elastic compression characteristics of an elastic vibration absorber using an adjusting member.

The structure of a conventional golf club head capable of absorbing vibration includes a head main body 100 and a vibration absorbing material 200 as shown in FIG. 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 accommodate the vibration absorbing material 200. The vibration absorber 200 is preferably selected from materials having a hardness between shore D 20 and 50, for example polyurethane (PU). Thereby, since the aftershock generated at the time of hitting can be appropriately absorbed by the vibration absorbing material 200 at the time of hitting, the comfort of gripping the user's hand can be relatively increased. There are some (see, for example, Patent Document 1).

  In the structure of the conventional golf club head capable of absorbing vibration as described above, when the golf ball starts to contact the face plate 101 in order to improve the accuracy of the hit ball and the controllability of the direction in the dynamic analysis, The plate 101 should preferably be subjected to the stress of a small ball and is rapidly formed into a large amount of compressive deformation. On the other hand, when the golf ball tries to move away from the face plate 101, the face plate 101 should preferably recover quickly from the maximum amount of elastic deformation to the current state, and thus have a relatively strong repulsive action. A force is formed and can be fed back to the golf ball. However, there is a problem that the face plate 101 is compressed so that the volume of the vibration absorbing material 200 is deformed because pressure is always generated in the face plate 101 in the period of continuous elastic deformation. . However, different players have different swinging powers and angles, and since there are various clubs with different lengths in a set of golf clubs, different ball hitting characteristics are emphasized between different club heads. A relatively long club requires a relatively long hit distance, while a relatively short club requires relatively good control, or slightly reduces the hit distance of a relatively long club. It is possible to obtain relatively good controllability, but because it has only the characteristics of a single hit ball that cannot be changed by a commercially available golf club head, the club head is balanced between the hit distance and controllability.

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

  1 and 2, the structure of the golf club head with adjustable vibration absorption according to the first embodiment of the present invention includes a head body 1, at least one elastic vibration absorber 2 and at least one adjusting member 3. . The head body 1 is composed of an iron-type head. A face plate 11 is coupled to the head body 1, and a cavity 12 and a storage chamber 13 are provided in the head body 1. The head body 1 can be hit with a golf ball using the face plate 11 by being connected to the face plate 11 by welding, brazing, fitting, screwing or integral molding. The cavity 12 is provided on the back of the head body 1 and the back surface of the face plate 11 is exposed to the cavity 12. The storage chamber 13 is provided so as to be recessed below the rear part of the head main body 11 and is preferably formed to be recessed in the back of the face plate 11 where sweet spots or aftershocks are concentrated. heel) or toe (toe) position. The opening of the storage chamber 13 is formed so as to face rearward, and is formed so as to communicate with the back surface of the cavity 12 and the face plate 11 facing forward. Further, the storage chamber 13 is preferably formed in a circular shape, and an inner screw 131 is formed on the inner peripheral wall of the storage chamber 13.

  Referring to FIGS. 1 and 2 again, the elastic vibration absorbing material 2 according to the first embodiment of the present invention is accommodated in the accommodating chamber 13 by a sticking or sliding method. The elastic vibration absorbing material 2 is composed of the airbag 21 and the air chamber 22, thereby forming a cushion effect by elasticity. The airbag 21 is made of an elastic material, for example, rubber, polyurethane (PU), thermoplastic elastomer, polymer elastic resin, or the like. The Shore hardness of the elastic material as described above is preferably controlled so as to be interposed between shore A10 and shore D30. The air chamber 22 is formed in a sealed shape so that an appropriate gas can be injected into the air chamber 22 and can be, for example, equal pressure or high pressure relative to the external atmosphere. The adjustment member 3 is preferably made of a screw, and the adjustment member 3 is provided with an external screw 31 and at least one recessed groove 32. Since the adjusting member 3 can be coupled to the inner screw 131 of the housing chamber 13 by the outer screw 31, the looseness with which the elastic vibration absorbing material 2 contacts the face plate 11 can be adjusted using the adjusting member 3. . Furthermore, the degree of screwing of the adjusting member 3 can be adjusted by adjusting the recessed groove 32 using a screwdriver or a tool such as a spanner.

  In the analysis of mechanics, when the head body 1 hits the golf ball, the golf ball undergoes the following steps according to the order: a) a stage in which the golf ball 11 starts to contact the face plate 11; c) This is the stage of finally leaving the face plate 11. In each of the above steps, when the face plate 11 is elastically deformed backward, pressure is always generated on the face plate 11 due to the continuous change. Therefore, the elastic vibration absorbing material 2 is pressed by the pressure and elastic vibration absorption is performed. Continuous compression deformation occurs in the volume of the material 2.

  Referring to FIG. 2, since the gas chamber 22 of the elastic vibration absorbing material 2 contains an appropriate amount of gas, the elastic vibration absorbing material 2 is provided with a cushion function by elasticity, and the elastic vibration absorbing material 2 further applies pressure. When it is received, it tends to be relatively elastically compressed. That is, in the step a), the face plate 11 starts to be elastically deformed, and even if a relatively small pressure is provided to the elastic vibration absorbing material 2, the volume of the elastic vibration absorbing material 2 increases as the pressure increases gradually. Can be promptly promoted to be compressed and reduced instantaneously, so that it is possible to effectively avoid excessive contact of the elastic vibration absorbing material 2 with the face plate 11 in the present invention. However, it is possible to delay the time for stopping at the face plate 11, but it is possible to ensure the performance of the entire hit ball. In the step b), the face plate 11 undergoes the maximum elastic deformation and the maximum pressure, and the elastic vibration absorber 2 is compressed by the pressure to a state close to the maximum compression volume. The absorber 2 abuts on and supports the face plate 11 and can relatively extend the contact time between the golf ball and the face plate 11 and further improve the direction controllability and the accuracy of the hit ball. In the step c), as the pressure generated from the face plate 11 gradually becomes zero, the volume of the elastic vibration absorbing material 2 quickly recovers to the original volume. Aftershock is caused by the stress of the partially hit ball that is not fed back from the golf ball to the golf ball. However, the elastic vibration absorber 2 is formed so as to be firmly adhered to the face plate 11 so that the aftershock can be effectively used. Can be absorbed, and the comfort of gripping the club can be further increased.

  Referring to FIG. 2 again, the looseness of the elastic vibration absorbing material 2 contacting the face plate 11 can be adjusted using the adjusting member 3 in the present invention. As described above, when the elastic vibration absorbing material 2 is adjusted to be relatively small before hitting the ball, the elastic vibration absorbing member 2 is preliminarily preliminarily compressed and further compressed to a relatively small volume in advance. Formed as follows. At this time, the elastic vibration absorber 2 is formed to have a relatively high vibration absorption effect. On the other hand, when adjusted so as to be relatively loose, the elastic vibration absorbing material 2 and the face plate 11 are formed so as to have a relatively large buffer deformation space or a loose fit degree of freedom. Since the elastic vibration absorbing material 2 does not excessively abut against the face plate 11 before performing the golf ball, it is possible to obtain an appropriate vibration absorbing effect and at the same time to ensure the performance of the hit ball. Since the contact time between the ball and the face plate 11 can be relatively extended, the controllability of the direction and the accuracy of the hit ball can be improved.

  Referring to FIG. 3, the structure of the golf club head with adjustable vibration absorption according to the second embodiment of the present invention is posted. Compared with the first embodiment, in the second embodiment, an appropriate amount of liquid 23 is simultaneously injected into the air chamber 22 of the elastic vibration absorbing material 2 in addition to an appropriate amount of gas being injected. The liquid 23 is selected from water, oil, gel fluid, non-corrosive aqueous solution, organic solution, mixed solution or adhesive solution. When the head main body 1 hits the ball, the liquid 23 in the air chamber 22 can absorb the aftershock of the head main body 1 using the resistance generated from the viscosity of the liquid. In addition, the elastic compression characteristics of the gas of the elastic vibration absorber 2 can be maintained by a part of the gas inside the air chamber 22.

  Referring to FIG. 4, the structure of a golf club head with adjustable vibration absorption according to the third embodiment of the present invention is posted. Compared with the first embodiment, in the third embodiment, the elastic vibration absorbing material 2 has a solid solid structure, and is initially accommodated in the accommodation chamber 13 by a slidable loose fit method. Similarly, the elastic vibration absorbing member 2 can adjust the looseness of contact with the face plate 11 by the adjusting member 3. The elastic vibration absorber 2 is formed to have a solid elastic compression characteristic. When the elastic vibration absorbing material 2 is adjusted so as to be relatively relaxed before hitting the ball, the elastic vibration absorbing material 2 is preliminarily preliminarily compressed and further compressed to a relatively small volume, so that it is formed so as to contact the face plate 11. The At this time, the elastic vibration absorber 2 is formed to have a relatively high vibration absorption effect. On the other hand, when adjusted so as to be relatively loose, the elastic vibration absorber 2 is formed so as to have a degree of freedom of rocking due to a relatively loose fit, and performs a small movement within the storage chamber 13. Can do. As described above, since the elastic vibration absorbing material 2 does not excessively contact the face plate 11 before hitting the ball, an appropriate vibration absorbing effect can be obtained and at the same time, the hit ball performance can be ensured. Furthermore, since the contact time between the golf ball and the face plate 11 can be relatively extended, the controllability of the direction and the accuracy of the hit ball can be improved.

  Referring to FIG. 5, a structure of a golf club head with adjustable vibration absorption according to a fourth embodiment of the present invention is posted. Compared with Example 3, in Example 4, the elastic vibration absorbing material 2 is manufactured in advance so as to be integrally formed with the adjustment member 3. That is, at the time of manufacture, the present invention preliminarily forms the adjusting member 3 using a metal material or a non-metallic material, and then injection-molds the elastic material at one end of the adjusting member 3 so that the elastic vibration absorbing material 2 is integrated. To form. Further, the adjustment member 3 and the elastic vibration absorbing material 2 can be formed integrally by using the same elastic material. Thereby, in the present invention, it is similarly formed to have the characteristic of elastic compression, and at the same time, the number of members can be relatively reduced and the assembling work can be simplified.

  As described above, according to the structure of the conventional golf club head with adjustable vibration absorption shown in FIG. 6, the solid vibration absorbing material 200 is used to be in close contact with the face plate 11. However, according to the structure of the golf club head with adjustable vibration absorption according to the present invention shown in FIG. 1, it is elastic to the rear of the face plate 11. By adhering the vibration absorbing material 2 and further adjusting the degree of freedom of looseness or loose fit that abuts against the face plate 11 using an adjusting member, the elastic compression characteristics can be reliably adjusted appropriately. At the same time, because the degree of freedom of sliding can be held, the overall performance of the hit ball is ensured, the controllability of the direction and the accuracy of the hit ball are improved, the aftershock is effectively absorbed, and the comfort of holding the club is further improved. Increase Can.

  The present invention may be implemented in other ways without departing from the spirit and essential characteristics thereof. Accordingly, the preferred embodiments described herein are illustrative and not limiting.
