Abstract

(57) [Summary] [Problem] To provide a golf club head capable of completely overcoming the repulsive vibration force when hit. SOLUTION: A rough surface is formed by spraying a sand-like material on the inner wall of a hollow storage chamber in a head main body made of stainless steel, and a plastic liquid is injected from a through hole in an upper wall of the head to uniformly spread the inner wall. The hollow rubber was injected into the hollow receiving chamber and filled.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a kind of golf club head, in particular, one in which rubber is filled in the head, has a high vibration absorption and vibration damping function, so that vibration at the time of impact does not cause a movement disorder to a hitter. About.

[0002]

[Prior art]

 Well-known golf club heads are integrally molded by a casting method, and golf club heads made of stainless steel are high in hardness and do not have instantaneous vibration absorption and vibration-absorbing functions at the time of impact. Could not control. Also, a head made of soft iron and manufactured by a forging method is expensive to mold (approximately 10 times that of casting), and is unsuitable for small-quantity production. Also, since soft iron is easily rusted, its surface needs to be electroplated, and the forged head manufactured in this way has almost the same hardness as that of the above-mentioned cast stainless steel, but at a cost of two. It took about 3 times, which also did not have the function of instantaneous vibration absorption and vibration absorption when hitting, so that the hitting distance and direction could not be effectively controlled. As described above, the well-known head does not have a vibration absorbing and damping function, and therefore, a large reaction force generated at the time of impact is transmitted to the batter's arm via the shaft, which may cause a movement disorder. For this reason, some companies may provide a product having a cushion member 20 provided in the rear end of the shaft 10 (FIG. 1), or make other improvements in order to effectively overcome the problem of the repulsive vibration force. However, it has not been able to provide sufficient vibration absorption and vibration reduction effects in actual use.

[0003]

[Problems to be solved by the invention]

 The present invention provides a kind of golf club head that can completely overcome the repulsive vibration force at the time of hitting, so that the hitter does not suffer from movement disorders and can control the hitting distance and direction effectively. In this golf club head, a rough surface is formed by spraying a sand-like material on the inner wall of a hollow storage chamber in a head body made of stainless steel, and a through hole is formed in an upper wall of the head. More plastic liquid will be injected and evenly distributed on the inner wall, and rubber isolator will be injected and filled into the hollow storage chamber.

[0004]

[Means for Solving the Problems]

 According to the invention of claim 1, a hollow housing chamber is provided in a range in a face inside a head body formed by integrally casting stainless steel, and a through-hole penetrating the hollow housing chamber is provided in an upper wall, and the hollow housing chamber is provided. A sandy substance is sprayed on the surface to make it rough, and a rubber liquid is injected from the through-hole to make it adhere evenly to the inner surface of the hollow storage chamber. The golf club head has a high vibration absorption and vibration absorption function by filling the hollow storage chamber with vibration rubber and directly absorbing vibration when hit by the vibration absorption rubber.

[0005] The invention according to claim 2 is characterized in that the through hole is provided at a position other than the upper wall of the head main body, and communicates the outside with the hollow accommodation chamber. The club head.

[0006]

[Embodiment of the invention]

 As shown in FIGS. 2 and 3, the golf club head according to the present invention includes a head main body 1 formed by integrally casting stainless steel, and a hollow accommodation chamber 13 is provided between the head main body 1 and the face 12. There is one through hole 14 in the upper wall of the head body 1, the inner surface of the hollow storage chamber 13 is blown with sand-like material to make a rough surface 15, and the rubber liquid 2 is injected into the hollow storage chamber 13 first. (FIG. 4), the rubber liquid 2 is uniformly applied to the inner wall of the hollow storage chamber 13, and then the anti-vibration rubber 3 is forcibly injected from the through hole 14 and filled into the hollow storage chamber 13, and the above is completed. (FIGS. 5 and 6). The position of the through hole 14 is not limited to the upper wall of the head main body 1 and may be an appropriate position of the head main body 1, provided that the hollow housing chamber 13 communicates with the outside. And

Since the inner surface of the hollow storage chamber 13 is roughened by spraying a sand-like substance, the rubber liquid 2 can easily adhere to the inner surface, and the vibration isolating rubber 3 can completely adhere to the inner wall. it can. In addition, the vibration isolating rubber 3 can be injected into the hollow storage chamber 13 using an injection molding machine, or can be forcedly injected into the hollow storage chamber 13 using a hydraulic machine by using a high-temperature and high-pressure method. The purpose of filling can be sufficiently achieved.

[0008] The actual manufacturing process will be described. First, a mixture obtained by mixing a small amount of filler into the vibration-isolating rubber 3 is placed in a hopper of an injection molding machine, preheated, and heated by an injection pipe. A rubber-like material 2 is injected by spraying a sand-like substance on the inner wall of the head body 1, the vibration isolating rubber 3 is injected and filled into the hollow accommodation chamber 13 of the head body 1, and the head body 1 is further sulfurized and formed by a mold. Remove and get the product as above. Naturally, there are restrictions on the temperature, time, and distribution ratio of the mixture in the actual manufacturing process, but the description is omitted because it is not the claim of the present invention.

In the golf club head of the present invention constituted as described above, the vibration at the moment when the face 12 hits is directly absorbed by the vibration isolating rubber 3 in the head main body 1, and therefore, a high vibration absorbing and vibration isolating effect is achieved. It is possible to prevent hitter's movement disorder.

[0010]

[Effect of the invention]

 The present invention has the following effects. 1. Since the head body 1 is made of cast stainless steel, it solves the disadvantages of forged soft iron, can be manufactured at low cost, has practical and economical advantages, and has an internal shock absorption function to effectively reduce the impact distance. Can control. 2. The repulsive vibration force generated at the time of hitting is partially absorbed by the face 12 and the rest is completely absorbed by the anti-vibration rubber 3 filled in the hollow accommodating chamber 13, so that the movement of the user can be impeded. Sex can be eliminated.

[0011] As described above, the golf club head of the present invention is significantly improved in its operation and effect as compared with known golf club heads. It is very practical and has commercial value.
