Description

[Technical Field]

[0001] The present invention relates to a grip attachment for ball games and ball game equipment. [Background technology]

[0002] Conventionally, attachments that are attached to the end of a grip for ball games such as a golf club have been used to attach training devices, electromagnetic sensors, or weights to the grip. For example, to properly handle a golf club, it is necessary to master the correct swing, and general golfers may use various training devices to master the correct swing. Examples of such training devices include the training devices described in the following Patent Documents 1 to 3, which have a training shaft structure connected to the end of the grip and extending toward the base end of the golf club in the axial direction.

[0003] As an example of the structure of an attachment for connecting the training device to the end of a grip, Patent Document 1 discloses a structure in which a slot 12 is formed in an outer diameter screw 14 having a cone-shaped outer shape, and a lock nut 06 is tightened onto the outer diameter screw 14 to fix a shaft 04 to a grip 18. Patent Document 2 discloses a structure in which a main body 1 is inserted into an iron grip 8 until a protrusion 5 is inserted into an iron grip hole 9, a belt 3 connected to the main body 1 is wound around the main body 1, and a hook-and-loop fastener of the belt 3 is attached to a hook-and-loop fastener 6 on the main body 1 to fix a directional rod 2. Patent Document 3 discloses a structure in which a fitting portion 12 having a slit 15 is fitted onto the end of a grip 52 so that a pin 18 of a lid portion 11 of a cap portion 10 is inserted into an air hole 53 of the grip 52, and the fitting portion 12 is fastened to the grip 52 by a band 20 and then fixed with a hook-and-loop fastener. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Registered Utility Model No. 3136701 [Patent Document 2] Japanese Patent Application Publication No. 2018-149252 [Patent Document 3] Japanese Patent Application Publication No. 2023-90134 Summary of the Invention [Problem to be solved by the invention]

[0005] In the above-mentioned conventional attachment devices, the training equipment is fixed to the grip by tightening the grip from the outer periphery. However, in Patent Documents 1 and 3, for example, the axial coverage area between the grip and the attachment device is small, resulting in insufficient fixing force and the training equipment not being able to be firmly fixed.

[0006] On the other hand, in Patent Document 2, the attachment covers a large portion of the grip in the axial direction (more than half in the drawing), and as the axial coverage range is large, the attachment comes into contact with the user's hand when gripped, causing an uncomfortable feeling during use.

[0007] Furthermore, in Patent Documents 2 and 3, fastening is performed using a belt and hook-and-loop fastener, which is not a problem if no external force is applied, but since grips used in ball games are often subjected to large external forces, it is possible that this may not be practical at all as a fixing means.

[0008] The present invention solves the above problems, and its object is to provide a grip attachment device for ball games that is used to attach various tools and other components to the grip of ball game equipment, and to provide a structure that can maintain a fixed state even when a large external force is applied while limiting the coverage area of ​​the grip in the axial direction. Also, an object is to provide ball game equipment that includes the above-mentioned grip attachment device. [Means for solving the problem]

[0009] In order to achieve the above-mentioned object, the grip attachment device for ball games of the present invention is an attachment device that is attached to the axial base end side of the grip of a ball game equipment, and is characterized by comprising: a base member having a first screw structure that can be screwed in from the axial tip side, and a support surface that receives and supports the end of the grip from the axial tip side; a screw-in member having a second screw structure that can be screwed into the first screw structure from the axial tip side toward the axial base end side, and an inclined inner surface portion that is inclined so that the inner diameter decreases toward the axial tip side; and a tightening member that is supported from the axial base end side by the base member, and whose tip portion on the axial tip side can be deformed in a diameter-reducing direction by the inclined inner surface portion of the screw-in member.

[0010] According to the present invention, when the threaded member is threaded into the first threaded member of the base member using the second threaded member from the axial tip end toward the axial base end, the tip end portion of the tightening member is pressed toward the outer peripheral surface of the grip. At this time, the inclined inner surface of the threaded member deforms the tip end portion of the tightening member in a radially reducing direction, forcing the tip end portion toward the outer peripheral surface of the grip. As a result, the grip is tightened from the outer peripheral side by the tip end portion of the tightening member, which is held axially between the base member, whose support surface abuts against the end portion of the grip, and the threaded member threaded into the base member, and is also held axially between the support surface of the base member and the tip end portion of the tightening member. As a result, the grip is less likely to escape toward the axial tip of the attachment, and can be firmly fixed by tightening force from the outer periphery, so the grip can be firmly fixed while limiting the axial coverage area of ​​the grip.

[0011] In the present invention, the tightening member is preferably made of a material that is more easily deformed than the material of the screw-in member. This allows the inclined inner surface of the screw-in member to firmly press the tip end portion of the tightening member, and because the tightening member is made of a material that is more easily deformed than the material of the screw-in member, the tip end portion of the tightening member can be flexibly tightened to match the shape of the grip and the shape of the outer peripheral surface, thereby further increasing the tightening force.

[0012] In the present invention, it is preferable that the tightening member has a cylindrical base portion provided on the base end side in the axial direction and integral about the axis that engages with the base member, and the tip portion consisting of a plurality of tongue-shaped portions protruding from the base portion toward the tip side in the axial direction and arranged about the axis by providing slits between each other. In this way, the tip portion of the tightening member that is deformed by the inclined inner surface of the screw-in member consists of a plurality of tongue-shaped portions separated about the axis, so that flexibly tightening can be performed in a manner that matches the outer peripheral surface of the grip while ensuring the unity of the pressing action including the component on the base end side in the axial direction by the inclined inner surface of the screw-in member and resistance to external forces.

[0013] In the present invention, when the attachment is fixed to the grip, it is preferable that the tip edge of the tip portion of the tightening member be pressed against the grip and be spaced axially further forward than the axially tip edge of the screw-in member. In this way, since there is no screw-in member on the outer periphery of the tightening member between the axially tip edge of the screw-in member and the edge of the tip portion of the tightening member, the edge side of the tip portion of the tightening member is exposed to the outside, and the tightening member is tightened to the grip in a state of being bent along the axial direction between the edge of the screw-in member and the outer periphery of the grip. Therefore, as the amount of threading of the screw-in member into the base member increases, the axially exposed area of ​​the edge side of the tip portion of the tightening member increases, and the tightening force gradually increases along with the curvature of the tip portion. This allows the tightening force on the grip to be further increased without changing the area of ​​coverage of the grip by the attachment.

[0014] In the present invention, the base member preferably further includes a holding member detachably attached to the base member body and having a connection structure for connecting other components. The base member preferably further includes a holding member detachably attached to the base member body and holding a pin that engages with a hole provided at the end of the grip. In this case, the holding member desirably holds the pin detachably and maintains its orientation. By configuring a holding member that holds a pin that engages with a hole provided at the end of the grip and has a connection structure for connecting other components, which is detachably attached to the base member, it is possible to select whether or not to use a pin depending on the presence, size, and position of a hole in the grip. Furthermore, by configuring a holding member to be able to hold different pins, it is possible to select whether or not to attach a holding member and to select various holding members. Furthermore, by providing a connection structure for other components on the holding member, it is possible to select and use different types of other components.

[0015] The ball game implement according to the present invention is a ball game implement equipped with a grip, and includes any one of the above-mentioned grip attachment devices attached to the end of the grip. In this case, it is preferable that the ball game implement further includes another component that is configured to be detachable from the base member of the ball game grip attachment device and extends toward the axial base end of the base member while connected to the base member. In this case, it is preferable that the grip has an outer surface shape whose diameter gradually increases from the axial tip end toward the axial base end.

[0016] In the present invention, the other component is preferably a training shaft extending axially toward the base end along the axis of the grip. In this case, it is desirable that the training shaft be configured to be detachable from the base member.

[0017] In the present invention, it is preferable that the base member further has a holding member that is configured to be detachable from the main body of the base member, holds a pin that engages with a hole provided at the end of the grip, and has a connection structure to which the other components can be connected. [Effects of the Invention]

[0018] According to this invention, a grip attachment device for ball games for attaching various tools and other components to the grip of a ball game implement can be realized, which has a structure that can maintain a fixed state even when a large external force is applied while restricting the coverage area of ​​the grip in the axial direction. Also, a ball game implement including the above-mentioned grip attachment device can be realized. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0020] Next, an embodiment of a grip attachment for ball games and a ball game implement according to the present invention will be described in detail with reference to the accompanying drawings. First, the overall configuration of the grip attachment for ball games according to the present invention will be described. In this embodiment, a golf club will be used as an example of the ball game implement.

[0021] FIG. 1 is an exploded perspective view showing the main components of a grip attachment for ball games according to this embodiment. The attachment 10 includes a base member 11, a screw-in member 12, and a fastening member 13. The base member 11 includes a detachable retaining member 14. As shown in FIG. 3, the base member 11 includes a base portion 11a provided at the axial base end and a first thread structure 11b provided at the axial tip end. The base member 11 also includes a large-diameter opening 11c at the axial tip end, a support surface 11d formed at the back of the opening 11c, and a mounting hole 11e passing through the support surface 11d along the axis inside the support surface 11d. The mounting hole 11e is internally threaded and can be threadedly engaged with a mounting screw 14b, which is a male thread of the retaining member 14. The outer peripheral surface of the base portion 11a is preferably knurled or has a surface treatment such as rubber to prevent slippage during screwing.

[0022] The first thread structure 11b of the base member 11 is not particularly limited, but in the illustrated example, it is a trapezoidal thread and is also a male thread formed on the outer peripheral surface. The angle difference between adjacent slant surfaces 11b1 and 11b2 of the thread of the first thread structure is 50-70 degrees, for example, 60 degrees. However, the first thread structure 11b may also be a triangular thread, square thread, ball screw, etc., and is not particularly limited to the illustrated example. The base member 11 is preferably made of a metal such as aluminum or an aluminum alloy.

[0023] As shown in FIG. 4, the threaded member 12 is generally cylindrical. A cylindrical main body 12a is provided at the axial base end. The outer peripheral surface of the main body 12a is preferably knurled to facilitate the threading operation, or is provided with a surface treatment such as rubber to prevent slippage during the threading operation. A second thread structure 12b is formed on the inner peripheral surface of the main body 12a, and this second thread structure 12b is configured to be threadably mateable with the first thread structure 11b of the base member 11. In the illustrated example, the second thread structure 12b is also a trapezoidal thread and a female thread, but like the first thread structure, this is not limited to the illustrated example. The angle difference between adjacent inclined surfaces 12b1 and 12b2 is 50-70 degrees, for example, 60 degrees.

[0024] The threaded member 12 has a tip portion 12c at its axial tip end, and the inner surface of the tip portion 12c forms an inclined inner surface portion 12d whose inner diameter decreases toward the axial tip end. While not particularly limited, in the illustrated example, the inclined inner surface portion 12d is a smooth, truncated cone. The threaded member 12 is preferably made of a metal such as aluminum or an aluminum alloy. The angle of the inclined inner surface portion 12d relative to the axis is preferably within the range of 3-30 degrees, and more preferably within the range of 5-20 degrees. The tip portion 12c has a tapered outer shape toward the axial tip end, which has the advantage of not interfering with the grip 2 when held by a user. In the illustrated example, the inclination angle of the inclined inner surface portion 12d is smaller than the inclination angle of the outer peripheral surface of the tip portion 12c, and the inclination range of the inclination range of the axial outer peripheral surface of the tip portion 12c is larger than the inclination range of the axial outer peripheral surface of the tip portion 12c. This makes it easier to ensure the thickness and rigidity of the tip portion 12c, thereby increasing the clamping force, and since the axial inclination range of the inclined inner surface portion 12d is wide, the deformation range of the tip portion of the clamping member 13 is increased, thereby ensuring a large axial clamping range of the grip 2.

[0025] 5, the fastening member 13 is provided with a base portion 13a integral with the axis on the base end side in the axial direction, and this base portion 13a fits into the opening 11c of the base member 11, and the edge of the base portion 13a can abut against the support surface 11d. Here, fitting the base portion 13a of the fastening member 13 into the opening 11c of the base member 11 ensures that the fastening member 13 is positioned in the mounting fixture 10. Furthermore, if the outer peripheral step formed on the axial tip side of the base portion 13a is configured to abut against the opening edge of the opening 11c, as in the illustrated example, the fastening member 13 can be more reliably supported by the base member 11 from the base end side in the axial direction.

[0026] The fastening member 13 also has a plurality of tongue-shaped portions 13b separated around the axis on its axial tip side. Each tongue-shaped portion 13b is integrally connected to the base portion 13a on its axial base side, and is separated from each other around the axis by a slit 13c. The slits 13c terminate at the axial base side with a substantially circular terminal portion 13d whose diameter is larger than the slit width. The slits 13c with such substantially circular terminal portions 13d allow the plurality of tongue-shaped portions 13b (four in the illustrated example) to deform radially while remaining substantially independent from each other. The outer peripheral surface 13b2 of the axial tip portion 13b1 of each tongue-shaped portion 13b is slightly tapered, so that the thickness gradually decreases toward the tip.

[0027] The material of the fastening member 13 is preferably a material with a low coefficient of friction, such as a material with a coefficient of friction of 0.1 or less, preferably 0.05 or less, with respect to the threaded member 12 (inclined inner surface 12d). Resin is particularly preferred. Examples of suitable materials include fluororesins such as polytetrafluoroethylene (PTFE), polyetheretherketone (PEEK), polyphenylene sulfide (PPS), polycarbonate, polyacetal, nylon, polyimide, polyester, carbon fiber reinforced resin, and glass fiber reinforced resin. This facilitates smooth sliding between the inclined inner surface 12d and the outer peripheral surface 13b2 when the inclined inner surface 12d of the threaded member 12 moves axially proximal to press the outer peripheral surface 13b2 of the tongue portion 13b inward. This ensures a strong and stable deformation of the tongue portion 13b and a secure fastening state to the outer peripheral surface of the end 2a of the grip 2.

[0028] Furthermore, it is desirable that the fastening member 13 be made of a material that is more easily deformed than the threaded member 12. In other words, the elastic modulus of the fastening member 13 is smaller than that of the threaded member 12. This makes it difficult for the inclined inner surface 12d of the threaded member 12 to deform, while the tongue-shaped portion 13b, which is the tip portion of the fastening member 13, is easily deformed. This ensures that the inclined inner surface 12d, which faces diagonally toward the base end in the axial direction, can press the tip portion (tongue-shaped portion 13b). Furthermore, the tip portion (tongue-shaped portion 13b) is also likely to deform in accordance with the inclined inner surface 12d, allowing the outer peripheral surface of the end portion 2a of the grip 2 to be securely fastened in a direction inclined toward the base end in the axial direction. From this perspective, it is also desirable that the fastening member 13 be made of a resin material.

[0029] As shown in FIG. 6, the holding member 14 has a base portion 14a provided on the base end side in the axial direction and a mounting screw 14b formed on the tip end side in the axial direction. In the holding member 14, a connection hole 14c opens in the base portion 14a on the base end side in the axial direction, and a shaft hole 14d opens in a tip end surface 14e on the tip end side in the axial direction. The connection hole 14c and the shaft hole 14d are connected to each other. The connection hole 14c has a larger inner diameter than the shaft hole 14d. In the illustrated example, a tool operating portion (wrench engagement portion) such as a hexagonal shape is formed on the base portion 14a. The holding member 14 is attached to the base member 11 by threading the mounting screw 14b into the mounting hole 11e of the base member 11 as described above. In this mounted state, when the flange portion 14f provided on the base portion 14a is fitted into the concave step portion 11f (see Figure 3) on the opening edge of the mounting hole 11e, the tip surface 14e of the holding member 14 is positioned along the support surface 11d of the base member 11.

[0030] 2 can be inserted into the connection hole 14c and the axial hole 14d of the holding member 14 from the side of the connection hole 14c, and the engagement pin 15 is positioned within the holding member 14 with its posture restricted, with the head 15a of the engagement pin 15 disposed within the connection hole 14c and the axial portion 15b disposed within the axial hole 14d. Note that, as shown in FIG. 2, when the engagement pin 15 is positioned within the holding member 14, the tip of the axial portion 15b protrudes axially toward the tip side beyond the tip surface 14e. The tip of the axial portion 15b of the engagement pin 15 engages with an end hole 2c formed in the center of the end surface 2b of the end portion 2a of the grip 2, allowing the end portion 2a to be positioned radially when the grip 2 is inserted into the mounting fixture 10.

[0031] In the illustrated example, the connection hole 14c is a structure for connecting other components, and the practice shaft 3 can be attached to a golf club, which is a ball game implement, by inserting (press-fitting) it into the connection hole 14c. The connection structure, such as the connection hole 14c of the holding member 14, is not limited to the hole structure in the illustrated example, and may be a housing section for housing weights (described later) and various sensors, and may be provided with a lid or mounting bracket for fixing these.

[0032] The wearing device 10 configured as described above is configured to be attachable to the end portion 2a on the base end side in the axial direction of the grip 2 of a ball game tool 1, which is a golf club, as shown in Fig. 2. Specifically, the wearing device 10 is assembled by inserting the base portion 13a of the fastening member 13 into the opening 11c of the base member 11, so that the edge of the base portion 13a abuts against the support surface 11d, thereby achieving a fitted state, and the second thread structure 12b of the screw-in member 12 is threaded into the first thread structure of the base member 11. In this assembled state, the end portion 2a of the grip 2 is inserted into the screw-in member 12 and the fastening member 13 from the tip side in the axial direction, so that the end surface 2b of the end portion 2a abuts against the support surface 11d and the tip surface 14e. Then, as the screw-in member 12 is screwed into the base member 11, the inclined inner surface 12d of the screw-in member 12 presses the tongue-shaped portion 13b of the fastening member 13 radially inward, causing the tongue-shaped portion 13b to deform radially inward and fasten the outer peripheral surface of the end portion 12a of the grip 2.

[0033] As the end 2a of the grip 2 is tightened by the tongue-shaped portion 13b pressed against the inclined inner surface 12d of the screw-in member 12, the tongue-shaped portion 13b pressed by the inclined inner surface 12d also tightens the end 2a with its inner surface inclined toward the base end in the axial direction, so that the end 2a is pressed toward the base end in the axial direction by the tightening force, and the end face 2b is fixed in a state where it is pressed against the support surface 11d and the tip surface 14e of the base member 11. At this time, the tightening member 13 is sandwiched from both sides in the axial direction between the support surface 11d and the tip surface 14e of the base member 11 and the inclined inner surface 12d. Furthermore, the multiple tongue-shaped portions 13b of the tightening member 13 are deformable independently of each other, so they flexibly deform according to the surface condition of the end 2a of the grip 2 while firmly fixing the grip 2.

[0034] When the attachment 10 is fixed to the grip 2 as described above, the practice shaft 3 can be inserted (press-fitted) into the connection hole 14c of the holding member 14 attached to the base member 11, thereby completing a practice tool equipped with the practice shaft 3 extending toward the base end of the ball game tool (golf club) 1. As described in the above-mentioned conventional Patent Documents 1-3, this practice tool allows a player to learn a correct swing by swinging the golf club (ball game tool) while positioning the practice shaft 3 next to the player's side.

[0035] In this embodiment, in the attachment 10, by screwing the threaded member 12 into the base member 11 toward the base end in the axial direction, the tongue-shaped portion 13b of the fastening member 13, which is sandwiched on both sides in the axial direction by the base member 11 and the threaded member 12, is fastened obliquely toward the base end in the axial direction by the inclined inner surface portion 12d of the tip end 12c of the threaded member 12, so that the end 2a of the grip 2 can be fastened in a state where it is sandwiched from both sides in the axial direction between the support surface 11d of the base member 11. Therefore, because the end 2a of the grip 2 is fastened from the outer periphery while being pressed toward the base end in the axial direction, the grip 2 can be firmly fixed while limiting the coverage area of ​​the grip 2, and therefore can withstand external forces during use.

[0036] In particular, by making the holding member 14 detachable from the base member 11, other parts such as the practice shaft 3 can be replaced as needed, and by replacing the holding member 14, the connection structure of the other parts can be changed, allowing for the attachment of a wider range of other parts. In addition, since the holding member 14 also contributes to the holding and attachment of the engagement pin 15, it can accommodate the presence or absence of the end hole 2c of the grip 2, and by replacing the engagement pin 15, it is also possible to change the shape of the engagement portion of the end hole 2c.

[0037] The grip attachment device for ball games and the ball game equipment according to the present invention are not limited to the above-described embodiments and can be modified in various ways without departing from the spirit of the present invention. For example, the above-described embodiments have been described using a golf grip attachment device and a golf club (golf equipment) as examples, but the present invention can be applied to various ball game equipment such as rackets, clubs, and bats for ball games other than golf, such as tennis, table tennis, badminton, hockey, baseball, and cricket. Furthermore, the other components are not limited to the practice shaft (rod-shaped member) described above, and may include weights for adjusting the center of gravity of the ball game equipment and various sensors for measuring swings, impacts, and speeds when hitting the ball.
