[I. Description of First Embodiment]
[1. Basic structure]
FIG. 1A is a perspective view illustrating a golf club 1 (putter) as a first embodiment. This golf club 1 has a head 3 , a hosel 4 , a shaft 5 and a grip 6 . A side surface of the head 3 is provided with a hitting surface 2 (face) for hitting a golf ball. As shown in FIG. 1B, the hosel 4 and the head 3 may be provided so as to be flush with the striking surface 2 (form the same plane). In the various examples of how the hosel 4 and head 3 are provided below, it should be noted that the hosel 4 and head 3 may be provided flush with the striking surface 2 as shown in FIG. 1(B). Needless to say.
2A to 2C are perspective views illustrating types of putter heads 3. FIG. The shape of the head 3 may be a pin type as shown in FIG. 2(A), a mallet type as shown in FIG. 2(B), or a shape as shown in FIG. 2(C). It may be of neo-mallet type.

The shaft 5 is formed in the shape of an axis (elongated rod), and one end (the lower end in FIG. 1) is connected to the head 3 via the hosel 4 . The cross-sectional shape of the shaft 5 may be circular, elliptical, or polygonal. A grip 6, which is a part to be gripped by the user, is provided at the other end of the shaft 5 (upper end in FIG. 1). Similar to the shaft 5, the cross-sectional shape of the grip 6 may be circular, elliptical, or polygonal.

The hosel 4 extends in a plane direction parallel to the striking face 2 and is shaped like a plate having a constant thickness. The hosel 4 is integrally formed with the head 3 and the shaft 5, for example in a non-replaceable manner. The shaft 5 may be connected to the end surface of the hosel 4 as shown in FIG. 3(A), or may be connected to the plate surface of the hosel 4 as shown in FIG. 3(B). Also, the thickness of the hosel 4 (dimension in the plate thickness direction) can be set independently of the thickness of the shaft 5 . If the shaft 5 is thicker than the hosel 4, the lower end of the shaft 5 may be processed to have a smaller cross-sectional area as shown in FIG. 3(C).

The width of the hosel 4 when viewed from the front can also be set independently of the thickness of the shaft 5 . For example, as shown in FIG. 3D, the width dimension of the hosel 4 may be set to be approximately the same as the thickness of the shaft 5 . Also, the hosel 4 may be formed in such a shape that the width dimension is reduced only at the upper end portion connected to the shaft 5 . In this case, the width of the upper end of the hosel 4 may be set to be approximately the same as the thickness of the shaft 5, as shown in FIG. 3(E). Alternatively, the upper end of the hosel 4 may be thinner than the shaft 5, as shown in FIG. 3(F).

The orientation of the hosel 4 fixed to the head 3 is set so as to extend in a plane direction parallel to the striking surface 2 . For example, the hosel 4 may be arranged parallel to the striking surface 2 as shown in FIG. 4(A). Alternatively, as shown in FIG. 4(B), the flat plate-like hosel 4 may be tilted (for example, with the upper portion tilted toward the striking surface 2). The shape of the lower end of the shaft 5 fixed to the hosel 4 may be a crank shape, a straight shape, or a bent shape, as shown in FIG. 4(A). may

The shape of the hosel 4 may be formed in the shape of a flat plate, or may be formed in the shape of a bent plate. In the case of a flat plate shape, as shown in FIG. 4A, it may be formed in a rectangular flat plate shape, or may be formed in a polygonal (triangular or pentagonal) flat plate shape. In the case of forming a bent plate shape, as shown in FIG. may be curved so that the side closer to the A side view of the golf club 1 shown in FIG. 4(C) is illustrated in FIG. 5(A).

Moreover, the shape of the hosel 4 may be formed in the shape of a trapezoidal flat plate. FIGS. 4(D) and 5(B) are diagrams showing the hosel 4 formed in a trapezoidal flat plate shape imitating the side shape of a horseshoe. The irregular quadrilateral of the hosel 4 shown in FIG. and The first side edge 52 is formed to form an angle A of 40 degrees or more and less than 50 degrees with respect to the lower edge 51 . Also, the second side edge 53 is formed to form an angle B of 120 degrees or more and less than 130 degrees with respect to the lower edge 51 .

In addition, as shown in FIG. 5(C), the shaft 5 may include extension mechanisms 55 and 56 . One extension mechanism 55 is a mechanism that can extend and retract in the extension direction of the shaft 5 (the vertical direction in the drawing), and is a mechanism for adjusting the vertical position of the head 3 with the grip 6 as a reference. Similarly, the other extension mechanism 56 is a mechanism that can extend and retract in a direction perpendicular to the extension mechanism 55 (horizontal direction in the drawing), and is a mechanism for adjusting the position of the head 3 in the horizontal direction. Also, the hosel 4 may incorporate the telescopic mechanism 57 . The extension mechanism 57 is a mechanism that can extend and retract in the vertical direction in the figure, and is a mechanism for adjusting the position of the head 3 in the vertical direction.

Furthermore, a slide mechanism 58 may be incorporated in the connecting portion between the hosel 4 and the head 3 . The slide mechanism 58 is a mechanism for adjusting the horizontal position of the hosel 4 with respect to the head 3 (or the horizontal position of the head 3 with respect to the hosel 4). The slide direction by the slide mechanism 58 may be the left-right direction in the drawing, or may be the direction perpendicular to the plane of the paper. Of course, as described above, the positions of the hosel 4 and head 3 can also be adjusted so that they are flush with the striking surface 2 as shown in FIG. 5(D). The hosel 4 and the head 3 are positioned so as to be flush with a surface 2' opposite to the striking surface 2 (this surface 2' can also be the striking surface 2) as shown in FIG. 5(E). It can also be adjusted. Furthermore, in the following embodiments, the surface opposite to the striking surface 2 can also be used as the striking surface.

As described above, by extending the planar hosel 4 with a constant thickness in parallel with the striking surface 2 , the vibration of the striking surface 2 is converted into planar vibration (membrane vibration) of the hosel 4 . As a result, the vibration is efficiently transmitted to the shaft 5 and the grip 6, and the user can feel the precise and delicate vibration. Therefore, it is possible to provide the user with a good hitting feeling, and improve the hitting feeling compared to existing golf clubs.

The head 3, hosel 4, shaft 5 and grip 6 may be integrally formed. The grip 6 may be formed separately from the other members 3-5. 6A and 6B are sectional views of the golf club 1 in which the head 3, hosel 4 and shaft 5 are integrally formed. Such a golf club 1 may be formed, for example, by casting, or may be formed by seamlessly joining individual parts formed separately by welding or welding. That is, the hosel 4 may be integrally formed with the head 3 and shaft 5 in a non-replaceable manner.

The inside of each of the head 3, hosel 4, shaft 5, and grip 6 may be formed hollow (having a cavity inside) or solid (having no cavity inside). . 7A and 7B are sectional views of the golf club 1 in which the head 3, the hosel 4, and the shaft 5 are hollow. Here, the hosel 4 has a hollow hosel cavity 8 (first cavity) therein. Similarly, the shaft 5 has a hollow shaft cavity 9 (second cavity) inside, and the head 3 has a hollow head cavity 7 (fourth cavity) inside. have. Each of head cavity 7 and shaft cavity 9 communicates with hosel cavity 8 .

8A and 8B are sectional views of the golf club 1 in which the inside of the hosel 4 is hollow and the insides of the head 3 and shaft 5 are solid. 9A and 9B are sectional views of the golf club 1 in which the inside of the hosel 4 and shaft 5 are hollow, and the inside of the head 3 is solid. Cavities can be formed in any of the head 3 , hosel 4 , shaft 5 and grip 6 .

By providing a cavity inside the head 3, hosel 4, shaft 5, grip 6, etc., the vibration of the striking surface 2 is also converted into the vibration of the air inside the cavity. As a result, the vibration of the striking surface 2 can be transmitted to the user not only as physical vibration but also as sound. In other words, the user can confirm the vibration of the hitting surface as sound, and the feeling of hitting can be improved. Also, as shown by broken lines in FIGS. 7B, 8B, and 9B, an opening 11 may be formed to communicate between the inner space of the hosel cavity 8 and the outside of the hosel 4. Alternatively, a head opening 12 may be formed to communicate between the internal space of the head 3 and the outside. As a result, the sound heard by the user can be made louder, and the hitting feeling can be further improved. The positions of the opening 11 and the head opening 12 may be on the side where the striking surface 2 is formed (front), on the opposite side (rear), or on the side. Only one of the openings 11 and 12 may be provided, or the openings 11 and 12 may not exist (the openings 11 and 12 may not be formed).

[2. Vibration transmission member]
A vibration transmission member 20 may be incorporated inside the golf club 1 . FIG. 10 is a cross-sectional view illustrating the internal structure of the golf club 1 in which the vibration transmission member 20 is built. Inside the golf club 1, not only a hosel cavity 8 and a shaft cavity 9 but also a grip cavity 10 are provided. The grip cavity 10 is a hollow (third hollow) formed inside the grip 6 and communicates with the shaft cavity 9 . The upper end of the grip 6 is closed by a grip upper end plate 21 .

The vibration transmission member 20 is a member that transmits vibration generated on the striking surface 2 to the grip 6 . The vibration transmitting member 20 is formed in an elongated shape and provided inside the hosel cavity 8 , the shaft cavity 9 , and the grip cavity 10 . Specific examples of the vibration transmitting member 20 include wires (for example, wires such as steel wires and piano wires), strings (for example, strings made by weaving various fibers), and rod members (for example, rod members made of bar-shaped metal or wood). , a linear elastic member (for example, a linear elastic member made of rubber or resin), an elongated coil spring, and the like.

One end (lower end in FIG. 10) of vibration transmitting member 20 is fixed to head 3 via fixture 22 . On the other hand, the other end of the vibration transmitting member 20 (upper end in FIG. 10) is attached to the inner peripheral surface of the grip 6 via an inner grip plate 23 and an inner grip fixture 24 (attachment member). As shown in FIG. 10, the vibration transmitting member 20 may be provided with a mass member 26 serving as a weight for amplifying vibration. The position of the mass member 26 may be fixed with respect to the vibration transmission member 20, or may be movable (adjustable fixed position). Also, for example, additional mass members 26 may be added according to the preference of the user.

Vibrations generated on the striking surface of the head 3 are transmitted not only to the grip 6 via the hosel 4 and shaft 5 but also to the grip 6 via the vibration transmission member 20 . By incorporating the vibration transmission member 20 in the shaft 5 in this way, the transmission path of vibration can be increased, and the vibration generated on the striking surface of the head 3 can be efficiently transmitted to the grip 6 without being damped. Therefore, it is possible to provide the user with a good hitting feeling, and improve the hitting feeling compared to existing golf clubs.

An in-grip plate 23 and an in-grip fixture 24 (mounting member) provided at the other end (upper end in FIG. 10) of the vibration transmitting member 20 are adjusted to extend the grip 6 by an electric or manual adjustment mechanism (not shown). It may be provided so that the position in the present direction can be adjusted. Thereby, the tension of the vibration transmitting member 20 can be adjusted, and the vibration can be transmitted to the grip 6 efficiently. In addition, the grip inner plate 23 may be formed in a film shape that extends in a direction intersecting the extending direction of the grip 6 (for example, a direction orthogonal to the extending direction of the grip 6). By forming the in-grip plate 23 in the form of a film, the in-grip plate 23 can vibrate in plane (membrane vibration), and the vibration transmission efficiency can be improved.

FIG. 11 is a cross-sectional view illustrating the internal structure of the golf club 1 in which the vibration transmission member 20 and the auxiliary vibration transmission member 30 are built.

Further, the end of the head base end portion 32 (right side in FIG. 11) is attached to the inner peripheral surface of the head 3 via a head base end side fixture 34 . An intermediate portion of the auxiliary vibration transmitting member 30 is attached to the inner peripheral surface of the head 3 via an in-head plate 35 and an in-head fixture 36 . Also, the auxiliary vibration transmitting member 30 and the in-head fixture 36 are bound by the binding portion 37 . A hole into which the auxiliary vibration transmission member 30 is loosely inserted is formed in the head inner plate 35 . The position of the in-head plate 35 is set near the striking surface 2, for example.

One end (lower end in FIG. 11) of the vibration transmitting member 20 is fixed to the auxiliary vibration transmitting member 30 via a connection fitting 27 . The other end (upper end in FIG. 11) of the vibration transmitting member 20 may be structured as shown in FIG. good. In the example shown in FIG. 11 , the intermediate portion of the vibration transmitting member 20 is attached to the inner peripheral surface of the grip 6 via the grip inner plate 23 and the grip inner fixture 24 . Also, the vibration transmitting member 20 and the in-grip fixture 24 are bound by the binding portion 25 . The grip inner plate 23 has a hole into which the vibration transmitting member 20 is loosely inserted. Two pairs of the in-grip plate 23 and the in-grip fixture 24 are provided.

Vibrations generated on the striking surface of the head 3 are transmitted not only to the grip 6 via the hosel 4 and shaft 5 but also to the grip 6 via the auxiliary vibration transmission member 30 and the vibration transmission member 20 . By incorporating the auxiliary vibration transmission member 30 in the head 3 in this way, the vibration transmitted to the vibration transmission member 20 can be amplified, and the vibration can be efficiently transmitted to the grip 6 . Therefore, it is possible to provide the user with a good hitting feeling, and improve the hitting feeling compared to existing golf clubs.

As shown in FIG. Here, the vibration transmitting member 20 is composed of a wire, a string, a linear elastic member, or an elongated coil spring. A motor 43 and a winding device 44 are provided at the other end of the vibration transmitting member 20 . A pinion 42 is rotatably attached to the motor 43 .

A rack 41 that meshes with the pinion 42 is fixed to the inner peripheral surface of the grip hollow portion 10 . The pinion 42 is urged upward with respect to the rack 41 by an unillustrated urging member (for example, spring or rubber). By rotating the motor 43 and winding the other end of the vibration transmitting member 20 with the winding device 44 , the pinion 42 is moved downward along the rack 41 . Further, by rewinding the motor 43 , the pinion 42 is moved upward along the rack 41 . With such a configuration, the position to which the vibration is transmitted can be easily adjusted in the extending direction of the grip 6, and the vibration can be transmitted to the grip 6 efficiently.

A manually operated winding device 44 may be used instead of the motor 43 . The winding device 44 may be provided so as to be externally rotated using a jig such as a Phillips screwdriver or a flat-blade screwdriver. In this case, the pinion 42 is moved downward along the rack 41 by manually rotating the winding device 44 to wind the other end of the vibration transmitting member 20 . Further, by winding the winding device 44 in the opposite direction, the pinion 42 is moved upward along the rack 41 .

[3. head]
FIGS. 14A and 14B are perspective views for explaining modifications of the head 3. FIG. As shown in these figures, the head 3 may incorporate a weight member 61 for changing the position of the center of gravity of the head 3 . In this case, the position of the center of gravity may be changed by making the mounting state (position and angle) of the weight member 61 adjustable. The mounting state of the weight member 61 may be manually adjusted by the user, or a weight motor 62 (driving source) for moving the weight member 61 may be provided.

FIG. 14A is a perspective view showing two sets of weight members 61 and weight motors 62 built in the upper surface of the head 3. FIG. The weight member 61 is made of a material having a density different from that of the material forming the head 3 , and is provided inside a hollow cylindrical recess formed in the upper surface of the head 3 . Further, the weight motor 62 changes the position of each weight member 61 by moving the weight member 61 in the rotational direction along the inner peripheral surface of the recess. With such a configuration, it is possible to easily change the position of the weight member 61 to move the center of gravity of the head 3, thereby providing a good hitting feel.

FIG. 14B is a perspective view showing that a weight member 61 is provided inside a linear concave portion provided in the upper surface of the head 3. FIG. The weight motor 62 changes the position of each weight member 61 by sliding the weight member 61 along the inner peripheral surface of the recess. Even with such a configuration, it is possible to easily change the position of the weight member 61 to move the center of gravity of the head 3, thereby providing a good hitting feel.

[4. effect]
(1) The golf club 1 in this case includes a head 3 , a shaft 5 , a hosel 4 and a grip 6 . The head 3 has a hitting surface 2 for hitting a golf ball. The shaft 5 is formed in the shape of an axis. A hosel 4 integrally connects one end of the shaft 5 and the head 3 in a non-replaceable manner. A grip 6 is provided at the other end of the shaft 5 and gripped by the user. By integrally forming the hosel 4 with the head 3 and the shaft 5 in such a state that the hosel 4 cannot be replaced, damping of vibrations passing through the hosel 4 can be suppressed, and the vibrations can be transmitted to the grip 6 efficiently. Therefore, the feel on impact can be further improved.

(2) The hosel 4 is shaped like a plate extending in a plane direction parallel to the striking face 2 and having a certain thickness. By extending the planar hosel 4 with a constant thickness in parallel with the striking surface 2 in this way, the vibration of the striking surface 2 is converted into planar vibration (membrane vibration) of the hosel 4 . As a result, the vibration is efficiently transmitted to the shaft 5 and the grip 6, and the user can feel the precise and delicate vibration. Therefore, it is possible to provide the user with a good hitting feeling, and improve the hitting feeling compared to existing golf clubs.

(3) The hosel 4 of the present invention is formed in a rectangular flat plate shape as shown in FIGS. can be Thus, by forming the hosel 4 in the shape of a rectangular flat plate, it is possible to improve the transmission efficiency of vibration with a simple configuration. Therefore, the feel on impact can be further improved.

(4) The hosel 4 in this case is a bent plate curved so that the side closer to the striking surface 2 faces inward in a longitudinal section perpendicular to the striking surface 2, as shown in FIGS. 4(C) and 5(A), for example. can be formed into a shape. With such a shape, the connection position between the shaft 5 and the hosel 4 can be brought closer to the striking surface in a top view while improving the vibration transmission efficiency. Therefore, it is possible to provide a good feel on impact. It is also possible to arrange the position of the golf ball when it contacts the striking surface 2 on the extension line of the shaft 5 .

The hosel 4 of the present invention can also be formed in a trapezoidal flat plate shape imitating the side shape of a horseshoe, as shown in FIGS. 4(D) and 5(B), for example. This scalene quadrilateral has a lower side 51 contacting the upper surface of the head 3 , a first side 52 forming an angle of 40 degrees or more and less than 50 degrees with respect to the lower side 51 , and an angle of 120 degrees or more and 130 degrees with respect to the lower side 51 . It has a second side 53 forming an angle of less than degrees and an upper side 54 connecting the first side 52 and the second side 53 and non-parallel to the lower side 51 . In this way, by adopting a planer shape of an irregular quadrilateral that imitates the side shape of a horseshoe as the shape of the hosel 4, the strength and rigidity of the hosel 4 can be ensured and a good hitting feel can be provided.

(5) The hosel 4 in this case can have a hollow hosel cavity 8 (first cavity) therein, as shown in FIGS. 7 to 9, for example. By forming such a hosel cavity 8 inside the hosel 4 , sound can be generated in the hosel cavity 8 . As a result, the user can confirm the vibration of the hitting surface 2 as sound, and the feeling of hitting can be further improved. Further, by forming the opening 11 for transmitting the reverberation sound of the hosel cavity 8 to the outside of the hosel 4, the sound heard by the user can be increased, and the hitting feeling can be further improved, and the hitting sound can be reduced. can be sufficiently verified.

(6) As shown in FIGS. 7 and 9, for example, the shaft 5 of this case has a hollow shaft cavity 9 (second cavity) communicating with a hosel cavity 8 (first cavity). can have By forming such a shaft cavity 9 in the shaft 5, the vibration can be echoed also in the shaft cavity 9, and the sound heard by the user can be increased. Therefore, the hitting feeling and hitting sound can be further improved.

(7) As shown in FIGS. 10 to 13, for example, the grip 6 of the present invention has a grip cavity 10 (third cavity) formed in a hollow that communicates with a shaft cavity 9 (second cavity). can have By forming such a grip hollow portion 10 in the grip 6, the vibration can be reflected in the grip hollow portion 10 as well, and the sound heard by the user can be increased. Therefore, the hitting feeling and hitting sound can be further improved.

(8) The grip 6 in this case can be formed integrally with the shaft 5, as shown in FIGS. 10 to 13, for example. If the shaft 5 and the grip 6 were separate members, the vibration would be attenuated when passing through the joint between them, and the vibration transmitted to the grip 6 might be reduced. Vibration can be efficiently transmitted to the grip 6 by integrally forming the shaft 5 and the grip 6 to solve such a problem. Therefore, the feel on impact can be further improved.

(9) For example, as shown in FIG. 10, the golf club 1 in this case may employ a vibration transmission member 20 that transmits vibration generated on the hitting surface 2 to the grip 6 . The vibration transmitting member 20 is formed in an elongated shape, one end of which is fixed to the head 3, and is housed in the shaft cavity 9 (second cavity) and the grip cavity 10 (third cavity). Further, inside the grip hollow portion 10 (third hollow portion), an inner grip plate 23 and an inner grip fixture 24 (mounting member) that connect the other end portion of the vibration transmitting member 20 and the grip 6 can be applied. . By incorporating the vibration transmitting member 20 into the shaft 5 and the grip 6 in this way, the vibration generated on the striking surface 2 of the head 3 can be efficiently transmitted to the grip 6 without being damped, and the feel of hitting can be further improved.

(10) For example, as shown in FIG. 13, a mounting member that connects the other end of the vibration transmitting member 20 and the grip 6 (a pinion 42, a motor 43, a winding device 44 in FIG. 13, or a manually operated winding The device 44 ) may be provided so that its position can be adjusted in the direction of extension of the grip 6 . With such a configuration, the position of the vibration transmitting member 20 to which the vibration is transmitted can be adjusted, and the vibration can be transmitted to the grip 6 efficiently. Therefore, the feel on impact can be further improved.
The grip inner plate 23 and the grip inner fixture 24 (mounting member) shown in FIG. 10 may be provided so that their positions in the extending direction of the grip 6 can be adjusted by an adjustment mechanism (not shown). Thereby, the tension of the vibration transmitting member 20 can be adjusted, and the vibration can be transmitted to the grip 6 efficiently.

(11) The vibration transmitting member 20 in this case can be composed of a wire, string, rod member, or linear elastic member. As a result, the vibration transmission member 20 can be realized with a simple configuration, and the vibration transmission efficiency can be easily improved. Therefore, the feel on impact can be further improved.

(12) In addition, the grip inner plate 23 (mounting member) in this case can be formed in a film shape that is deployed in a direction intersecting the extending direction of the grip 6 . By forming the grip inner plate 23 (mounting member) into a film shape, surface vibration (membrane vibration) can be generated, and vibration transmission efficiency can be improved. Therefore, the feel on impact can be further improved.

(13) As shown in FIGS. 10 and 11, the vibration transmitting member 20 may be provided with a mass member 26 serving as a weight for amplifying vibration. By providing the mass member 26, the vibration of the vibration transmission member 20 can be easily amplified, or damping of the vibration can be suppressed, and the vibration transmission efficiency can be improved. Therefore, the feel on impact can be further improved.

(14) The head 3 in this case can have a hollow head cavity 7 (fourth cavity) communicating with the hosel cavity 8 (first cavity). By forming such a head cavity portion 7 in the head 3, the vibration can be reflected also in the head cavity portion 7, and the sound heard by the user can be increased. Therefore, the feel on impact can be further improved.

(15) As shown in FIGS. 11 and 12, for example, an auxiliary vibration transmission member 30 that transmits vibration generated on the hitting surface 2 to the vibration transmission member 20 can be applied to the golf club 1 of the present case. The auxiliary vibration transmission member 30 is provided inside the head cavity portion 7 (fourth cavity portion). By incorporating the auxiliary vibration transmission member 30 in the head 3 in this way, the vibration generated on the striking surface 2 of the head 3 can be efficiently transmitted to the vibration transmission member 20 without being damped, and the hitting feeling can be further improved.

(16) As shown in FIGS. 14A and 14B, a weight member 61 for changing the position of the center of gravity of the head 3 can be applied to the head 3 of this case. By changing the attachment position and attachment angle of the weight member 61, the center of gravity of the head 3 can be easily moved, and a good feel can be provided.

(17) As shown in FIG. 14(A), a weight motor 62 may be provided as a drive source for moving the weight member 61 . In this case, the weight member 61 is provided, for example, inside a hollow columnar recess formed in the upper surface of the head 3 . Further, the weight motor 62 rotationally drives the weight member 61 along the inner peripheral surface of the recess. With such a configuration, the weight motor 62 can be used to easily adjust the center of gravity of the head 3 . Therefore, the feel on impact can be further improved.

[5. Modification]
The example according to the first embodiment is merely an example, and there is no intention of excluding various modifications and application of techniques not explicitly described in this example. Each configuration of the examples according to the first embodiment can be modified in various ways without departing from the gist thereof. Also, they can be selected or combined as needed.

For example, as shown in FIG. 15, the hosel 4 may incorporate a vibration sensor 81 that detects vibrations occurring on the striking surface 2 . The vibration sensor 81 may be attached to the outer surface of the hosel 4 or may be incorporated. If the hosel cavity 8 is formed inside the hosel 4, the vibration sensor 81 may be arranged inside. By detecting vibration with the vibration sensor 81, it is possible to objectively grasp the magnitude and waveform of the vibration in the vicinity of the vibration source (hitting surface 2), thereby further improving the hitting feel. In addition, the magnitude and waveform of vibration can be analyzed, and by utilizing the analysis results, it is possible to enhance the effect of golf practice. Information detected by the vibration sensor 81 may be transmitted to a computer (not shown) through, for example, a wireless connection or a wired connection.

Alternatively, the grip 6 may incorporate a vibrating device 82 that vibrates based on vibration information detected by the vibration sensor 81 . If the grip cavity 10 is formed inside the grip 6, the vibrating device 82 may be arranged inside. The vibrating device 82 may function, for example, to amplify and output the vibration detected by the vibration sensor 81 as it is. By amplifying the vibration with the vibrating device 82, the vibration actually transmitted to the user can be increased, and the hitting feeling can be further improved.

Further, the grip 6 may incorporate a speaker 82A that emits sound based on information on vibration detected by the vibration sensor 81. FIG. If the grip cavity 10 is formed inside the grip 6, a speaker 82A including an amplifier may be placed inside. The speaker 82A may function so as to amplify and output the vibration detected by the vibration sensor 81 as it is as a sound, for example. As a result, when a golf ball is hit with one hitting surface of the golf club, the vibration at that time is detected by the vibration sensor 81 and is heard as sound from the speaker 82A. At this time, the hollow shaft 5 functions as a speaker box and amplifies and outputs the sound related to the vibration. As a result, the golf club 1 can function as a kind of electronic musical instrument.
Of course, both the vibration device 82 and the speaker 82A may be attached to the grip 6.

Further, as shown in FIGS. 16A and 16B, thin plate-like fins 13 may be erected on the upper surface of the head 3 . The fin 13 is a thin plate-like or hollow plate-like portion that functions to amplify vibrations generated in the head 3 and the hosel 4 . The number of fins 13 may be appropriately set according to the size of the head 3 and the hosel 4, and may be one or two or more. Further, the fins 13 may be arranged on the side closer to the striking surface 2 or on the side farther from the striking surface 2 than the position of the hosel 4 to which the shaft 5 is connected.

In addition, as shown in FIGS. 16A and 16B, the height of the fins 13 may be set to the same (or substantially the same) height as the hosel 4 . Alternatively, as shown in FIGS. 16C, 16D, and 16E, the height of the fins 13 may be different from that of the hosel 4, or may be set to about half the height of the hosel 4, for example. In this manner, the size relationship between the hosel 4 and the fins 13 (thickness, height, depth) can be appropriately set. Further, the fins 13 arranged near the hosel 4 may be formed integrally with the hosel 4 or may be formed separately.

Also, an illumination member 13B containing, for example, an LED or a fluorescent material can be arranged on the top surface 13A of the fin 13. FIG. Alternatively, an illumination member 4B similar to the illumination member 13B may be arranged on the top surface 4A of the hosel 4. FIG. The illumination members 4B and 13B may be, for example, one or more, and may be arranged in a plane, in a row, or in a chain. In this way, the trajectory of the head 3 can be sufficiently confirmed even during practice in the dark. Note that the lighting member 4B may be omitted.

17(A), (B), and (C), the shape of the fins 13 may be curved (crescent shape) in top view, or As shown in F), it is also possible to use one having a corrugated shape when viewed from above. Of course, as for the shape of the fins 13, it is also possible to use a combination of curved shapes and waveform shapes, and furthermore, other shapes when viewed from the top can also be used. When using the fins 13 having such a shape, the hosel 4 can also be curved or wavy. Then, by making it into a curved shape or a wavy shape when viewed from above, a fluctuation effect is produced, and a sense of balance can be given to the user.

Further, as shown in FIGS. 17(G) and (H), the longitudinal direction of the head 3 may be formed so as to coincide with the swinging direction of the head 3 (see the solid line arrow or the broken line arrow) when viewed from above. A U-shaped fin 13 may be provided on the upper surface of the head 3 . The number of fins 13 may be one or plural. The orientation of the fins 13 is preferably set such that the U-shape opens toward the hitting surface 2 when viewed from above. The positions of the hosel 4 and the head 3 can be flush with the striking surface 2 as shown in FIGS. 17(C), (F) and (H).

18A and 18B are cross-sectional views illustrating the internal structure of the golf club 1 shown in FIG. 16A. By providing the fins 13 on the upper surface of the head 3, vibration can be easily amplified. Further, when a plurality of fins 13 (these fins 13 may be linear, curved, or wavy when viewed from above), vibrations resonate between them. can be further amplified by Therefore, it is possible to provide the user with a good hitting feeling and hitting sound, and to provide a structure having the same effects as the above-described embodiment.

The position of the mass member 26 may be fixed with respect to the vibration transmission member 20, or may be movable (adjustable fixed position). Further, for example, the mass member 26 may be added, changed, or replaced according to user's preference.

Vibrations generated on the striking surface of the head 3 are transmitted not only to the grip 6 via the shaft 5 but also to the grip 6 via the vibration transmission member 20 . By incorporating the vibration transmission member 20 in the shaft 5 in this way, the transmission path of vibration can be increased, and the vibration generated on the striking surface of the head 3 can be efficiently transmitted to the grip 6 without being damped.

In addition, the grip inner plate 23 may be formed in a film shape that extends in a direction intersecting the extending direction of the grip 6 (for example, a direction orthogonal to the extending direction of the grip 6). By forming the in-grip plate 23 in the form of a film, the in-grip plate 23 can vibrate in plane (membrane vibration), and the vibration transmission efficiency can be improved.

FIG. 20 is a cross-sectional view illustrating the internal structure of the golf club 1 in which the vibration transmission member 20 and the auxiliary vibration transmission member 30 are built. A head cavity portion 7 (fourth cavity portion) is provided inside the head 3 of the golf club 1, and an auxiliary vibration transmission member 30 is attached therein.

In the example shown in FIG. 20 , the intermediate portion of the vibration transmitting member 20 is attached to the inner peripheral surface of the grip 6 via the grip inner plate 23 and the grip inner fixture 24 . Also, the vibration transmitting member 20 and the in-grip fixture 24 are bound by the binding portion 25 . The grip inner plate 23 has a hole into which the vibration transmitting member 20 is loosely inserted. Two pairs of the in-grip plate 23 and the in-grip fixture 24 are provided.

[III. Description of the third embodiment]
The third embodiment relates to a golf club 1 characterized by inserts provided on the hitting surface 2 of the head 3 . As shown in FIG. 23, this golf club 1 has a head 3, a shaft 5 and a grip 6. As shown in FIG.

A side surface of the head 3 is provided with a hitting surface (face) 2 for hitting a golf ball. The hitting surface 2 is provided with an insert consisting of a plane vibrating member 15 which is formed in a planar shape to vibrate in plane upon collision with the golf ball and to give a reaction force to the golf ball. As a result, it is possible to efficiently apply a reaction force to the ball with a small force, thereby extending the carry. Surface vibration can improve hitting feel.

As shown in FIG. 24, for example, the planar vibration member 15 has a net member 16 formed by weaving strings 19 in a net shape inside a frame 18, and covers the entire surface of the net member 16 and is attached to the striking surface 2. It has a membrane member 17 . This net member 16 has, for example, a structure similar to that of a tennis racket. Thereby, a reaction force can be efficiently applied to the ball. It is preferable that each of the net member 16 and the film member 17 can be individually attached to and detached from the striking surface 2 of the head 3 .

At least one of natural fibers [gut (cattle, sheep intestines)], synthetic fibers (nylon fibers, polyester fibers), and elastic fibers (natural rubber fibers, synthetic rubber fibers) is used as the string 19 constituting the net member 16. The film member 17 includes at least one of a metal plate, a resin plate, a rubber film and a leather film. As a result, by reusing existing strings (tennis strings, rubber belts, etc.), it is possible to realize net members at low cost, and by reusing existing membrane products (drum membranes, rubber membranes for table tennis rackets, etc.), A membrane member can be realized at low cost. Furthermore, the net member 16 and the membrane member 17 can be integrally formed to have the same structure as the hitting surface structure of a table tennis racket, or the net member 16 can be made of a drum skin stretched over a frame member.
