There is a problem in that the fiber-containing resin layer peels off from the wood-based core member due to shocks and vibrations that occur over time, creating gaps between raindrops. As a result, the golf club does not have a feel similar to that of a wood-based golf club, which is a characteristic of the above-mentioned golf club, and the rotational stress of the internal wood-based core member is reliably transmitted to the face of the resin layer containing miscellaneous metals, resulting in a high impact force. and could not get direction. The present invention was invented in order to solve the above-mentioned conventional drawbacks, and its purpose is to provide 1! To provide a method for manufacturing a golf club that can integrate a miscellaneous resin layer for a long period of time, provide an excellent shot feeling, and provide high impact force and directionality. There is a particular thing. [Means for Solving the Problems] Therefore, the present invention provides a fiber-containing resin layer having a higher specific gravity than that of the wood core member on the outer peripheral surface of the wood core member to which the shaft is integrally attached to the socket portion. In the coated golf club, a large number of recesses are formed on the outer peripheral surface of the wood core member, and then an m-fiber-containing resin layer is placed on the outer peripheral surface of the wood core member such that a part of the resin layer is locked in the recesses. It is characterized in that it constitutes a method of manufacturing a golf club by forming a coating.

The fiber-containing resin layer is integrated with the wood-based core member by the adhesive force of the resin, and a portion of the fiber-containing resin layer is immersed in and locked in the four parts. For this reason, it is possible to prevent the ill-containing resin layer from shifting relative to the wood-based core member at the time of impact with the ball, and to maintain the integration of the two over a long period of time. Further, the invention according to claim 2 provides that the outer circumferential surface of the wooden core member has m.
After the N-containing resin layer is coated, the fiber-containing resin layer is integrated with the wood core member by the adhesive force of the resin. At this time, part of the fiber-containing resin layer sinks into the four parts and is locked by the locking member. For this reason, it is possible to prevent the IINI resin layer from shifting relative to the wood-based core member at the time of impact with the ball, and to maintain the integration of the two over a long period of time. Furthermore, the invention according to claim 3 forms a recess on the outer peripheral surface other than the face where the IJAN-containing resin layer is relatively thin,
Since the volume increase of the fiber-containing resin layer corresponding to the locking member is absorbed by the recess, appearance defects such as wrinkles on the surface are prevented from occurring.

提供することかできる。An embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is a partially cutaway perspective view of the golf club, and Fig. 2 is a partially cutaway perspective view of the golf club.
The core member 3 of the golf club 1 is made of persimmon, oak, maple, ash, etc. or a wood laminate with a specific gravity of about 0.6 to 0.9, and the heel side of the figure is a cross-sectional view taken along the line II-II. A socket portion 3a is integrally formed therein. A mounting hole 3b is formed in the socket portion 3a, and a shaft 5 is inserted and fixed into the mounting hole 3b. A recess 3C is formed on the face surface of the core member 3, and the fiber-containing resin layer 7 covered by the recess 3C is thicker on the face side. A large number of dimples 3d as recesses are formed on the outer circumferential surface (top surface, bottom surface, heel surface, toe surface, and outer surface of the socket part 3a) of the core member 3 excluding the face surface, and the core member 3 corresponds to each dimple 3d. A locking member 9 is implanted therein. This locking member 9 has a locking portion 9a at its upper end and is made of, for example, a wood screw. Further, a plurality of locking members 9 are implanted in a diamond shape on the face surface of the core member 3. The size and depth of the dimple 3d are determined by the core member 3.
The fiber-containing resin layer 7 covered with the fiber-containing resin layer 7 is locked in an anchor-like manner to prevent its position from shifting, and it also almost coincides with the volume increase opening by the locking member 9 to prevent appearance defects such as wrinkles. is set to . I
An INI resin layer 7 is formed so as to have a thickness of about 7 to 9 inches on the face surface and about 315 inches on other parts. This IIN-containing resin layer 7 has a higher specific gravity than the core member 3, and is composed of, for example, a carbon lIH-containing resin layer, a Kepler fiber-containing resin layer, a boron m miscellaneous-containing resin layer, and a whisker fiber-containing resin layer. As this fiber-containing resin layer 7, for example, long carbon fibers are cross-woven, and a fabric prepreg containing an epoxy-based or polyester-based thermosetting synthetic resin is used.
In this case, the specific gravity is set to about 1.7 to 1°8. Note that a sole plate 11 made of, for example, an aluminum alloy is fixed to the sole surface of the golf club 1 in which the outer peripheral surface of the core member 3 is coated with the fiber-containing resin layer 7, and a back weight 13 is screwed to the back surface. ing. Next, a method for manufacturing the golf club 1 having the above structure will be described. The outer circumferential surface of the core member 3 has the locking members 9 implanted in accordance with each dimple 3d, and the core member has the locking members 9 implanted therein. After laminating a plurality of fabric prepregs to the required thickness on the face surface of the core member 3, heat compression molding is performed. On the other hand, the fiber-containing resin layer 7 is integrated by the adhesive force of the resin. At this time, due to compression, IIN
A portion of the resin-containing layer 7 sinks into the dimple 3d and is located around the locking member 9, particularly around the locking portion 9a. In this case, if the gold-containing resin layer 7 is coated without forming the dimples 3d, on the outer circumferential surface of the core member 3 except for the face surface where the coating thickness is relatively thin, there will be locks that protrude to the outside. A portion of the fiber-containing resin layer 7 becomes redundant depending on the volume of the member 9, and appearance defects such as wrinkles occur on the surface of the fiber-containing resin layer 7 corresponding to the locking member 9. However, due to the dimples 3d, The increase in volume of the fiber-containing resin layer 7 due to the locking member 9 is absorbed to avoid appearance defects such as wrinkles. On the other hand, on the face side, l
Since the thickness of the IIN-containing resin layer 7 is relatively thick, the increase in volume of the locking member 9 is absorbed by the thickness of the IIN-containing resin layer 7 without providing the dimples 3d, resulting in appearance defects such as wrinkles. is avoided. When the ball is impacted by the golf club 1 manufactured as described above, the fiber-containing resin layer 7 is displaced from the core member 3 from the face side toward the back side due to the impact, and the fiber-containing resin layer 7 is displaced from the core member 3 by the impact. Although the reaction force j that peels off the fiber-containing resin layer 7 acts, the position f of the m-thickness-containing resin layer 7 coated on the core member 3 is displaced by the recessed dimple 3d and the locking member 9 integrated around it. Therefore, peeling from the core member 3 is restricted. In this way, in this embodiment, the golf club 1
When the core member 3 is brought back, the dimple 3d provided on the outer circumferential surface of the core member 3 and the locking member 9 planted in accordance with the dimple 3d allow the locking member 3 to be released from the core member 3! Since displacement of the 1ift-containing resin layer 7 is restricted, it is possible to prevent the fiber-containing resin layer 7 from peeling off from the core member 3 and maintain the integration of the two over a long period of time. As a result, it is possible to obtain a shot feel similar to that of a wood-based golf club over a long period of time, and the rotational stress of the core member 3 can be reduced to II.
High impact force and directionality can be obtained by reliably acting on the ball through the N-containing resin layer 7. In the above description, a large number of dimples 3d as recesses are formed on the outer peripheral surface of the core member 3, and the locking members 9 are implanted in accordance with the dimples 3d. However, when carrying out the invention according to claim 1, The core member 3 is formed by forming a drilled hole, a hole with a shape that bulges out inside, and filling the hole with fiber-containing resin to obtain an anchor effect! A method of increasing the adhesion strength with the IN-containing resin layer 7 may be used. In addition, the above description is based on the fiber-containing resin layer 7 on the outer peripheral surface of the core member 3.
A back weight 13 is attached to the back side of the golf club 1 which is coated with wood.However, among the so-called wood golf clubs, for example, the back weight is not attached to the No. 1 club, and the back weight is attached to the other golf clubs. It may also be something to which weights are attached. That is, the back weight does not limit the technical scope of the present invention. [Effects of the Invention] Therefore, the present invention is suitable for wood-based core members! To provide a method for manufacturing a golf club in which a resin layer containing I miscellaneous materials can be integrated for a long period of time, an excellent shot feeling can be obtained, and high impact force and directionality can be obtained. I can do it.
