This application is a continuation application of International Application PCT/JP2023/006319, filed on Feb. 21, 2023, and designated the U.S., which claims priority to Japanese Patent Application No. 2022-024435, filed on Feb. 21, 2022, the entire contents of each are incorporated herein by reference.
FIELDThe present disclosure relates to a golf club for striking a golf ball and a golf club insert that is detachably provided on the golf club.
BACKGROUNDAs a related golf club such as a wood, an iron, a hybrid, a utility, and a putter, one in which a shaft with a grip is connected to a head via a hosel. The hosel is, for example, detachably connected to the shaft and the head. This configuration makes it easy to replace a head and a shaft (see Patent Documents 1 and 2).
On the other hand, a golf club not having a hosel, which is one in which a shaft with a grip is connected to a head, has also been known to the public.
Related Art Reference Patent DocumentFor example, a related art is disclosed in JP2021-058337 A and JP2014-036894 A.
In a golf club having a hosel, vibration generated when the golf ball is hit is transmitted to the palm of the user (golfer) that holds the grip via the shaft and recognized as part of impact feeling of the golf club. However, the hosel interposed between the shaft and the head may act to hinder the transmission of such vibration. For this reason, a golf club having a hosel less brings preferable impact feeling than a golf club 1 not having a hosel. Here, the “impact feeling” means sense of touch and the shooting feeling that the user experiences when striking a golf ball. Typical impact feeling includes sensory comfort (feeling) of the impact, such as sense of impact, feeling of control and sense of accomplishment as well as physical vibration.
In addition, a golf club not having a hosel has difficulty in bringing preferable impact feeling unless being contrived in some extent.
SUMMARYWith the foregoing problems in view, one of the objects of the present embodiment is to provide a golf club and a golf club insert that can enhance the impact feeling. In addition to this object, actions and effects that are derived from each configuration “embodiment(s) to carry out disclosure” to be described below and that related techniques do not attain can be regarded as other object of the present embodiment.
The present embodiment can be achieved in the following embodiments and applications. The disclosed golf club and golf club insert solves at least part of the above problems.
(1) The present golf club comprises a shaft formed in a shaft shape; a head being provided at a first end portion side of the shaft and having a striking surface that strikes a golf ball; a grip being provided at a second end portion side of the shaft and being gripped by a user; a hosel that connects the first end portion of the shaft to the head, and that is integrally formed with the head and the shaft in an unreplaceable state; and an impact-vibration/impact-sound emphasizing mechanism that emphasizes impact vibration or impact sound generated when the striking surface strikes the golf ball and transmits the emphasized impact vibration or emphasized impact sound to the user, wherein the impact-vibration/impact-sound emphasizing mechanism comprises a diaphragm member that is attached to the hosel and that emphasizes the impact vibration generated when the golf ball is hit.
(2) The present golf club comprises a shaft formed in a shaft shape; a head being provided at a first end portion side of the shaft and having a striking surface that strikes a golf ball; a grip being provided at a second end portion side of the shaft and being gripped by a user; a hosel that connects the first end portion of the shaft to the head; and an impact-vibration/impact-sound emphasizing mechanism being provided inside the golf club, that emphasizes impact vibration or impact sound generated when the striking surface strikes the golf ball and transmits the emphasized impact vibration or emphasized impact sound to the user, wherein the impact-vibration/impact-sound emphasizing mechanism comprises a vibration transmitting member formed in an elongated shape, having a first end being fixed to the head and transmitting vibration generated at the striking surface to the grip, and an installing member connecting a second end portion of the vibration transmitting member to the grip, the installing member is provided such that the position thereof is adjustable in an extending direction of the grip, and the installing member comprises a winding device that winds the second end portion of the vibration transmitting member manually or electrically, and a pinion that meshes with a rack and that is rotatably wound by the winding device.
(3) The present golf club comprises a head having a striking surface that strikes a golf ball; a shaft formed in a shaft shape; a hosel that connects a first end portion of the shaft to the head; a grip being provided at a second end portion of the shaft and being gripped by a user; and a fin or a plate-shaped member between the head and the hosel, wherein the fin or the plate-shaped member is formed by a plate-like member and is fixed so as to connect the head to the hosel in a direction substantially parallel to the striking surface.
EffectsIncluding the impact-vibration/impact-sound emphasizing mechanism, the disclosed golf club can emphasize the impact vibration and the impact sound generated on the head when the golf ball is hit, so that the impact feeling can be enhanced.
In addition, the disclosed golf club, if being variously contrived, can efficiently transmits the impact vibration generated on the head when the golf ball is hit to the shaft even when the golf club is not provided with a hosel, so that the impact feeling can be enhanced.
Furthermore, by providing an insert on the head striking surface, the disclosed golf club not having a hosel can efficiently transmit the impact vibration generated on the head when the golf ball to the shaft, so that the impact feeling can be enhanced.
The shaft 5 is formed in an axial shape (elongated rod shape), and one end portion (first end portion, lower end portion in
The hosel 4 is formed into a plate shape that extends in a plane direction parallel to the striking surface 2 and that has a constant thickness. The hosel 4 is formed integrally with the head 3 and the shaft 5, for example, in a non-replaceable manner. As shown in
Likewise, the width Dimension the hosel 4 when viewed from the front can be set irrespective of the thickness of the shaft 5. For example, as shown in
The direction 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, as shown in
The hosel 4 may be formed in a flat plate shape or may be formed in a bent plate shape. If being formed into a flat plate shape, the hosel 4 is formed into a rectangular flat plate shape as shown in
The hosel 4 may be formed in a flat plate shape having an irregular quadrilateral shape.
As illustrated in
Further, a slidable mechanism 58 may be built into a connection point between the hosel 4 and the head 3. The slidable mechanism 58 is a mechanism that adjusts the position in the horizontal direction of the head 3 with respect to the hosel 4 (or the position in the horizontal direction of the head 3 with respect to the hosel 4). The sliding direction of the slidable mechanism 58 may be a left-right direction in the drawing or a direction perpendicular to the sheet of the drawing. Of course, as described above, the positions of the hosel 4 and the head 3 can be adjusted so as to be flush with the striking surface 2 as shown in
As described above, stretching the hosel 4 in a planar shape having a constant thickness in parallel to the striking surface 2 makes it possible to convert the vibration of the striking surface 2 into the surface vibration (membrane vibration) of the hosel 4. With this structure, the vibration is efficiently transmitted to the shaft 5 and the grip 6, so that the user can feel accurate and subtle vibration. Therefore, it is possible to provide the user with preferable impact feeling, and to enhance the impact feeling as compared with an existing golf club.
The head 3, the hosel 4, the shaft 5, the grip 6 may be integrally formed. The grip 6 may be formed separately from the other members 3 to 5.
The interior of each of the head 3, the hosel 4, the shaft 5, and the grip 6 may be formed in a hollow (a state in which there is a cavity therein) or solid (a state in which there is no cavity therein).
By providing cavities inside the head 3, the hosel 4, the shaft 5, the grip 6 and the like, the vibration of the striking surface 2 is also converted into the vibration of the air in the cavities. This structure can transmit the vibration of the striking surface 2 in the form of acoustic sound as well as physical vibration to the user. Accordingly, the user can confirm the vibration of the striking surface in the form of acoustic sound, and can enhance the impact feeling. Further, as shown by dashed lines in
A vibration transmitting member 20 may be built into the golf club 1.
The vibration transmitting 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 is provided inside the hosel cavity 8, the shaft cavity 9, and the grip cavity 10. Examples of the vibration transmitting member 20 include a wire (e.g., a wire such as a steel wire or a piano wire), a string (e.g., a string in which various fibers are braided), a rod member (e.g., a rod member formed of rod-shaped metal or wood), a linear elastic member (e.g., a linear elastic member formed of rubber or resin), and an elongated coil spring.
One end portion (first end portion, lower end portion in
Vibration generated on the striking surface of the head 3 are transmitted to the grip 6 via not only the hosel 4 and the shaft 5 but also the vibration transmitting member 20. As described above, by incorporating the vibration transmitting member 20 in the shaft 5, the transmission paths of the 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 attenuated. Therefore, it is possible to provide the user with preferable impact feeling, and to enhance the impact feeling as compared with an existing golf club.
The grip inner plate 23 and the grip inner fixing device 24 (installing members) provided at the second end portion (upper end portion of
An end portion of head distal tip portion 31 (the left side in
One end portion (lower end portion in
Vibration generated on the striking surface of the head 3 are transmitted to the grip 6 via not only the hosel 4 and the shaft 5 but also the auxiliary vibration transmitting member 30 and the vibration transmitting member 20. As described above, by incorporating the auxiliary vibration transmitting member 30 in the head 3, the vibration transmitted to the vibration transmitting 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 preferable impact feeling, and to enhance the impact feeling as compared with an existing golf club.
To the inner circumference surface of the grip cavity 10, a rack 41 that meshes with the pinion 42 is fixed. The pinion 42 is urged upward against the rack 41 by a non-illustrated urging member (for example, a spring or a rubber). The pinion 42 is moved downward along the rack 41 by rotating the motor 43 and winding the second end portion of the vibration transmitting member 20 by the winding device 44. In contrast, by rewinding the motor 43, the pinion 42 is moved upward along the rack 41. This structure makes it possible to adjust the position where the vibration is transmitted in the extending direction of the grip 6 with ease, so that the vibration can be efficiently transmitted to the grip 6.
Instead of the motor 43, a manually operated winding device 44 may be used. The winding device 44 may be configured to be rotated from the outside by using, for example, a jig such as a Phillips screwdriver or a flat-blade screwdriver. In this case, the second end of the vibration transmitting member 20 is wound by rotating the winding device 44 by hand, so that the pinion 42 is moved downward along the rack 41. The pinion 42 is moved upward along the rack 41 by rewinding the winding device 44 in the reverse direction. With this configuration, the position where the vibration is transmitted can be manually adjusted to the extending direction of the grip 6 with ease, so that the vibration can be efficiently transmitted to the grip 6.
3. Head(1) The golf club 1 of this embodiment includes the head 3, the shaft 5, the hosel 4, and the grip 6. The head 3 has the striking surface 2 that strikes a golf ball. The shaft 5 is formed in an axial shape. The hosel 4 integrally connects the head 3 with a first end portion of the shaft 5 in a non-replaceable manner. The grip 6 is provided at the second end portion of the shaft 5 and is gripped by the user. In this way, by forming the head 3 and the shaft 5 integrally with the hosel 4 in a non-replaceable manner, vibration passing through the hosel 4 can be inhibited from being attenuated and vibration can be efficiently transmitted to the grip 6. Consequently, the impact feeling can be further enhanced.
(2) The hosel 4 is formed into a plate shape that extends in a plane direction parallel to the striking surface 2 and that has a constant thickness. In this manner, stretching the hosel 4 in a planar shape having a constant thickness in parallel to the striking surface 2 makes it possible to convert the vibration of the striking surface 2 into the surface vibration (membrane vibration) of the hosel 4. With this structure, the vibration is efficiently transmitted to the shaft 5 and the grip 6, so that the user can feel accurate and subtle vibration. Therefore, it is possible to provide the user with preferable impact feeling, and to enhance the impact feeling as compared with an existing golf club.
(3) The hosel 4 of the present embodiment may be formed in a rectangular flat plate shape as shown in
(4) As shown in

(7) As shown in
(8) The grip 6 of the present embodiment may be integrally formed with the shaft 5 as shown in
(9) For example, as shown in
(10) For example, as shown in
In addition, the grip inner plate 23 and the grip inner fixing device 24 (installing members) shown in
(11) The vibration transmitting member 20 of the present application may be formed of any one of a wire, a string, a rod member, and a linear elastic member. As a result, the vibration transmitting member 20 can be realized with a simple configuration, and the vibration transmission efficiency can be easily improved. Consequently, the impact feeling can be further enhanced.
(12) In addition, the grip inner plate 23 (installing member) of the present application can be formed in a membrane shape that is expanded in a direction intersecting the extending direction of the grip 6. By being formed into a membrane shape, the grip inner plate 23 (installing member) can be surface-vibrated (membrane-vibrated), so that the vibration transmission efficiency can be enhanced. Consequently, the impact feeling can be further enhanced.
(13) As shown in
(14) The head 3 of the present embodiment may have a head cavity 7 (fourth cavity) formed into a hollow communicating with the hosel cavity 8 (first cavity) therein. By forming such the head cavity 7 inside the head 3, the head cavity 7 can also reverberate vibration and the acoustic sound that the user hears can be increased. Consequently, the impact feeling can be further enhanced.
(15) As shown in
(16) As illustrated in
(17) As shown in
The above first embodiment is merely example, and there is no intention to eliminate the application of various modifications and techniques not explicitly described therein. The configurations of the first embodiment can be variously modified without departing from the scope thereof. Also, the configuration can be selected or omitted according to the requirement or appropriately combined.
For example, as shown in
Further, the grip 6 may include a vibrating device 82 that vibrates based on the data of the vibration detected by the vibration sensor 81. In a case where the grip cavity 10 is formed inside the grip 6, a vibrating device 82 may be arranged inside the cavity. The vibrating device 82 may function, for example, to amplify and output the unprocessed vibration detected by the vibration sensor 81. By amplifying the vibration by the vibrating device 82, the vibration actually transmitted to the user can be increased, so that the impact feeling can be further enhanced.
Further alternatively, the grip 6 may include a speaker 82A that emits sound based on the data of the vibration detected by the vibration sensor 81. In a case where the grip cavity 10 is formed inside the grip 6, a speaker 82A including an amplifier may be arranged inside the cavity. The speaker 82A may function, for example, to amplify and output the vibration detected by the vibration sensor 81 in the form of unprocessed sound. As a result, when a golf ball is struck on one striking surface of the golf club, the vibration at that time is detected by the vibration sensor 81 and heard, as sound, from the speaker 82A. At this time, the hollow shaft 5 functions as a speaker box, and therefore makes the sound related to the vibration louder and outputs the loud sound. As a result, the golf club 1 can function as a kind of electronic musical instrument.
Of course, both the vibrating device 82 and the speaker 82A may be attached to the grip 6.
As shown in
As illustrated in
In addition, an illuminating member 13B including, for example, an LED or a fluorescent material may be arranged on a top surface 13A of each fin 13. Alternatively, illuminating member 4B equivalent to the illuminating member 13B may be arranged on the top surface 4A of the hosel 4. The number of each of the illuminating members 4B and 13B may be, for example, one or more, and the illuminating members 4B and 13B may be arranged in a planar shape, in a row shape, or in a chain shape. This structure makes it possible to sufficiently confirm the trajectory of the head 3 even during practice in darkness. The illuminating member 4B may be omitted.
Furthermore, the fins 13 formed into curved shapes (crescent shapes) in the top view as shown in
Further alternatively, as shown in
The second embodiment relates to a golf club 1 which does not have hosel 4 unlike the first embodiment. In the golf club 1 of the second embodiment, the shaft 5 and the grip 6 are formed into hollows, and the vibration transmitting member 20 is provided in the hollow portions.
In other words, the vibration transmitting member 20 is incorporated in the golf club 1 not having the hosel 4.
The vibration transmitting 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 is provided inside the shaft cavity 9 and the grip cavity 10. Examples of the vibration transmitting member 20 include a wire (e.g., a wire such as a steel wire or a piano wire), a string (e.g., a string in which various fibers are braided), a rod member (e.g., a rod member formed of rod-shaped metal or wood), a linear elastic member (e.g., a linear elastic member formed of rubber or resin), and an elongated coil spring.
One end portion (lower end portion in
The vibration generated on the striking surface of the head 3 is not only transmitted to the grip 6 via the shaft 5, but also transmitted to the grip 6 via the vibration transmitting member 20. As described above, by incorporating the vibration transmitting member 20 in the shaft 5, the transmission paths of the 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 attenuated. Therefore, it is possible to provide the user with preferable impact feeling, and to improve the impact feeling as compared with an existing golf club.
The grip inner plate 23 and the grip inner fixing device 24 (installing members) provided at the other end portion (upper end portion of
An end portion of head distal tip portion 31 (the left side in
One end portion (lower end portion in
Vibration generated on the striking surface of the head 3 are transmitted to the grip 6 via not only the shaft 5 but also the auxiliary vibration transmitting member 30 and the vibration transmitting member 20. As described above, by incorporating the auxiliary vibration transmitting member 30 in the head 3, the vibration transmitted to the vibration transmitting 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 preferable impact feeling, and to enhance the impact feeling as compared with an existing golf club.
To the inner circumference surface of the grip cavity 10, a rack 41 that meshes with the pinion 42 is fixed. The pinion 42 is urged upward against the rack 41 by a non-illustrated urging member (for example, a spring or a rubber). The pinion 42 moves downward along the rack 41 by rotating the motor 43 and winding the second end portion of the vibration transmitting member 20 by the winding device 44 In contrast, when rewinding the motor 43, the pinion 42 moves upward along the rack 41.
Instead of the motor 43, a manually operated winding device 44 may be used. The winding device 44 may be configured to be rotated from the outside by using, for example, a jig such as a Phillips screwdriver or a flat-blade screwdriver. In this case, the second end of the vibration transmitting member 20 is wound by rotating the winding device 44 by hand, so that the pinion 42 is moved downward along the rack 41. The pinion 42 is moved upward along the rack 41 by rewinding the winding device 44 in the reverse direction. With this configuration, the position where the vibration is transmitted can be manually adjusted to the extending direction of the grip 6 with ease, so that the vibration can be efficiently transmitted to the grip 6.
In the embodiments shown in
The third embodiment relates to a golf club 1 characterized by an insert provided on the striking surface 2 of the head 3. As shown in
On the side surface of the head 3, a striking surface 2 (face) that hits a golf ball is provided. The striking surface 2 is provided with an insert made of a surface vibration member 15 formed in a surface shape that, when colliding with the golf ball, surface-vibrates and provides reaction force to the golf ball. This structure can efficiently apply reaction force to the ball by small force and to extend the driving distance. The impact feeling can be improved by the surface vibration.
For example, as shown in
The string 19 constituting the net member 16 includes at least one of natural fibers (gut (bovine and ovine intestine)), synthetic fibers (nylon fiber, polyester fiber), and elastic fibers (natural rubber fibers, synthetic rubber fibers), and the membrane member 17 includes at least one of a metal plate, a resin plate, a rubber membrane, and a leather membrane. Accordingly, by using existing string (e.g., tennis strings, rubber belts), the net member can be achieved at low cost, and by using existing membrane products (e.g., drum membrane, rubber membrane of a table tennis racket), the membrane member can be realized at low cost. Alternatively, the net member 16 and the membrane member 17 may be integrally formed to have a structure similar to the hitting surface structure of a table tennis racket, or the net member 16 may be formed by stretching the membrane of a drum may over a frame material. Further alternatively, the insert may be made of metal. In this case, the insert may be formed in a lattice shape like the lid of a grating.
The structure of the insert may be formed into one similar to a gong structure. Specifically, if the striking surface 2 of the insert is hang and the ball hits the striking surface 2 in the gong structure, a sound like a gong is generated.
If the net member 16 is formed by stretching a drum membrane over a frame material or if the striking surface 2 of the insert is formed into a gong structure, a vibration sensor that detects vibration of a drum membrane or vibration of an insert in the gong structure is provided, for example, inside of the head of the golf club or integrally with or close to the insert and the vibration of the drum membrane or the insert in the gong structure may be amplified and output in the form of sound from a speaker.
The surface vibration member 15 is detachably provided to the head 3. This allows the surface vibration member 15 to be attached or detached according to the preference of the user. In addition, the surface vibration member 15 may be attached to an existing golf club. Like the head cavity 7 of the first embodiment, a head cavity 7 formed by forming a hollow inside of the head 3 may be provided. For example, as shown in
In addition, a head inner wire (auxiliary vibration transmitting member) 30 may be installed inside the head cavity 7. The head inner wire 30 is stretched inside the head cavity 7 and connected to the surface vibration member 15 via a connecting wire 40. This can amplify the surface vibration of the surface vibration member 15 as the vibration of the head inner wire 30, and can enhance the impact feeling.
As shown in
Furthermore, as shown in
In the event of hitting a golf club with the golf club, if the golf ball hits the sweet spot of the striking surface 2 of the insert, a chime, a gong, or a buzzer sounds as electronic sound, or the fact is notified via voice. The tone of the chime, the gong, or the buzzer may differ between a case where the golf ball hits the sweet spot and a case where the golf ball does not hit the sweet spot, or the voice may differ between the above cases. For this case, a sensor that detects that a golf ball hit the sweet spot or a sensor that detects that the golf ball missed the sweet spot is provided, and a speaker outputs sound of the chime, the gong, or the buzzer or voice via an amplifier on the basis of the data detected by this sensor (or these sensors).
Of course, the golf club having the insert head according to the third embodiment can also be applied to a golf club having a hosel according to the first embodiment. In other words, the insert like those shown in
The fourth embodiment relates to a golf club 1 having a fin or plate member 86. The golf club 1 shown in
The fin or plate member 86 is a plate-like member and is fixed so as to connect the head 3 to the hosel 4 in a direction substantially parallel to the striking surface 2. The fin or plate member 86 shown in
The golf club 1 shown in
The fifth embodiment relates to a golf club 1 including the vibration transmitting member 20 and the auxiliary vibration transmitting member 30 and further incorporating therein pickups 20A,30A (first pickup 20A, second pickup 30A) that detect vibration. The first pickup 20A is a sensor that detects vibration of the vibration transmitting member 20 and converts the detected vibration into an electric signal, and is provided at a position close to the vibration transmitting member 20. Similarly, the second pickup 30A is a sensor that detects vibration of the auxiliary vibration transmitting member 30 and converts the detected vibration into an electric signal, and is provided at a position close to the auxiliary vibration transmitting member 30. These pickups 20A, 30A generate electric signals corresponding to the vibration of the vibration transmitting members 20, 30 in the manner accomplished by an electric guitar, for example.

As shown in
In the golf club 1 shown in
In the golf club 1 shown in
In particular, if the golf club 1 includes the vibration transmitting member 20 and the auxiliary vibration transmitting member 30, the pickups 20A, 30A detect vibration transmitting through the vibration transmitting member 20 and the auxiliary vibration transmitting member 30 respectively, the electric signals originated from the respective vibrations are amplified by the amplifiers 90A,90B, appropriately filtered, and output as impact sound from the speakers 91A, 91B. This can provide more preferable impact feeling the user.
The speakers 91A,91B can be in shared, and amplifier 90A,90B can also be shared as needed. As shown in
Further, as shown in
Specifically, as shown in
Also in these golf clubs 1, the same actions and effects as those of the above-described the golf club 1 having the hosel 4 can be obtained. Of course, even in these examples, speakers 91A-91C can be shared, and amplifiers 90A-90C can also be shared as needed. In addition, in the golf club 1 including multiple vibration transmitting members 20, auxiliary vibration transmitting members 30, and the connecting wires 40, the pickups 20A,30A, 40A may be provided one for each of the vibration transmitting members 20, the auxiliary vibration transmitting member 30, and the connecting wires 40 or may be shared by the vibration transmitting members 20, the auxiliary vibration transmitting member 30, and the connecting wires 40.
In this embodiment, the amplifiers 90A-90C and the speakers 91A-91C may be replaced with a smart phone or a computer (e.g., information terminal). In this case, the speakers 91A-91C may be worn to the user's ears in the form of earphones or headphones. The connection between the pickups 20A,30A,40A and the respective corresponding amplifiers 90A-90C may be wired or wireless. Similarly, the connection between the amplifiers 90A-90C and the respective corresponding speakers 91A-91C may be wired or wireless.
VI. Sixth EmbodimentIn the sixth embodiment, on the upper surface of the head 3 of the golf club 1, a Liquid Crystal Display (LCD) 100 serving as an electric indicator member that can indicate the hitting direction of the golf ball is provided. The LCD 100 may be configured, for example, as a color LCD that can display color images. The LCD 100 can also be applied to the golf club 1 having the hosel 4 as shown in
As shown in
The display by the LCD 100 may be an arrow or a series of circles indicating the hitting direction of the golf ball. In the latter case, the circles may be arranged so as to become smaller as approaching the distal end side indicating the direction. This configuration can enhance the impact feeling and also can display the hitting direction of the golf ball freely with the LCD 100, so that the convenience can be enhanced.
The indicator 102 and the controller 101 may be replaced by a smart phone. In this case, the connection between the controller 101 and the LCD 100 is preferably wireless. Further, the content of an instruction input into the indicator 102 may be input by, for example, a user of the golf club 1, an instructor (trainer), or an assistant (caddy).
In the present embodiment, in addition to displaying the hitting direction of the golf ball with the LCD 100, a rhythm box function for notifying the rhythm of hitting the golf ball in the event of hitting the golf ball may be provided. For this case, the golf club 1 is provided with a controller 101 having either one of a rhythm box function for notifying the rhythm when the golf ball is to be hit and a synthesized voice generating function and a speaker 100A outputting one of the rhythm sound and the synthesized voice generated by the rhythm box function and the synthesized voice generating function of the controller 101, respectively (see
Furthermore, one or more impact sensors 103 may be provided in the head 3, and when the golf ball hits the striking surface 2, the impact data thereof may be detected by the impact sensors 103 and collected by the controller 101, and the impact data may be displayed on the LCD 100 in a numerical value and/or a graph (see
In addition, if the head 3 is configured to be able to detect the difference in impact data between the sweet spot on the striking surface 2 and the other position, the impact data when the golf ball hits the sweet spot and when the golf ball does not hits the sweet spot can also be displayed on the LCD 100 in a numerical value and/or a graph via the controller 101. In this case, it is preferable that the impact data in a numerical value and/or a graph is displayed after the hitting direction of the golf ball is displayed. Alternatively, the hitting direction and the impact data may be alternately displayed at predetermined intervals.
VII. MiscellaneousThe adapters 3A, 3B are assumed to be selected one therefrom and mounted to the lower surface of the head 3 by the user or the instructor (trainer), for example. The adapters 3A,3B are preferably mounted to the lower surface of the head 3 via, for example, a locking structure (clips) or a fastening structure (screw) that can be easily detached. By using the adapters 3A,3B suitable for the physique and the striking form of the user of the golf club 1, the swing trajectory of the golf club 1 can be easily optimized, and the practice effectiveness can be enhanced. Incidentally, the lie angle Lis an angle on the user's side from the shaft 5 between angles that the shaft 5 forms with respect to the horizontal plane when the striking surface 2 of the head 3 is viewed horizontally from the front.
