Technical Field

[0001] This utility model relates to a golf club, a neck and a club head assembly. Background Technology

[0002] A golf club is disclosed in Japanese Patent Application Publication No. 2011-224367. The golf club disclosed in Japanese Patent Application Publication No. 2011-224367 has a collar, a clubhead, and a shaft. The collar is connected to the neck of the clubhead. The shaft is inserted into the collar. The shaft is formed of a fine-fiber reinforced resin material for lightweight purposes. To ensure sufficient strength in connecting the shaft to the clubhead, Japanese Patent Application Publication No. 2011-224367 describes a structure in which the collar is supported by covering the shaft from the outer periphery. Utility Model Content

[0003] In the golf club disclosed in Japanese Patent Application Publication No. 2011-224367, a collar with an angle adjustment function is used to allow adjustment of the clubhead and shaft angles. However, if the collar of Japanese Patent Application Publication No. 2011-224367 is used, a structure with a large outer diameter appears around the neck of the clubhead. Therefore, in golf clubs, a technology is desired that allows for adjustment of the shaft and clubhead angles while also enabling a slimmer appearance.

[0004] The purpose of this invention is to solve the above-mentioned problems.

[0005] The first aspect of this utility model is a golf club, comprising: a shaft having a grip; a clubhead connected to the shaft; and a collar connecting and fixing the clubhead to the shaft; the clubhead having a mounting hole receiving and holding the collar, the collar having an insert and an angle adjustment component, the insert being inserted into the shaft and the mounting hole, the angle adjustment component adjusting the angle of the insert relative to the clubhead; the shaft having a receiving hole at its top end for receiving the insert; the shaft being connected to the insert on a side closer to the base end than the angle adjustment component; and the shaft being located at the outermost periphery at the connection point with the collar.

[0006] The second embodiment of this utility model is a shaft neck that connects the shaft and head of a golf club, comprising: an insert that is inserted into the head and shaft; and an angle adjustment component for adjusting the angle of the insert relative to the head, the angle adjustment component having: an annular protrusion that bulges radially outward from the insert; and a plurality of annular members disposed relative to the annular protrusion in the apical direction and surrounding the outer periphery of the insert, the outer diameter of the annular protrusion and the outer diameter of the annular members having the same size.

[0007] The third embodiment of this utility model is a club head assembly comprising: a neck as described in the second embodiment; and a club head having a mounting hole, wherein the neck is fixed to the mounting hole.

[0008] According to this invention, the appearance around the neck of the clubhead can be made thinner. Attached Figure Description

[0013] (One implementation method)

[0014] Figure 1 This is a perspective view of a golf club 10 according to one embodiment. The rear perspective view of the golf club 10 is shown below. Figure 1 As shown in the image.

[0015] Figure 2 This is a schematic diagram showing the connection relationship between the shaft 12, the neck 16, and the clubhead 14.

[0016] In addition, Figure 1 , Figure 2 The diagram also shows the top direction D1 and the base direction D2. The top direction D1 is parallel to the axis of the rod body 12 (main body 18) described later, and is the direction from the base end 12b to the top end 12t described later. Figure 1 The base direction D2 shown is the opposite direction to the tip direction D1. The length direction described later is the collective term for the tip direction D1 and the base direction D2.

[0017] The golf club 10 includes a shaft 12, a clubhead 14, and a neck 16. The golf club 10 is, for example, a putter, and the clubhead 14 is, for example, a putter head, but is not limited thereto.

[0018] The shaft 12 has a main body 18 and a grip 20.

[0019] The main body 18 is a rod-shaped component. The material of the main body 18 includes, for example, steel. The main body 18 has a top end portion 12t, which is one end of the rod body 12 along its length, and a base end portion 12b, which is the other end of the rod body 12. A receiving hole 22 is provided at the top end portion 12t (see reference). Figure 2 A grip 20 is mounted on the base end 12b. The grip 20 is the part that the golfer holds.

[0020] The clubhead 14 is the part that strikes the golf ball. The clubhead 14 has a mounting hole 24. The mounting hole 24 is a hole that receives and holds the neck 16. The mounting hole 24 is formed in the neck 141 of the clubhead 14. Although not shown in the diagram, the mounting hole 24 extends from the neck 141 along the tip direction D1 and extends through to the tip direction D1 side of the clubhead 14. The clubhead 14 is connected to the shaft 12 via the neck 16.

[0021] Figure 3 This is a perspective view showing the neck 16 and the threaded component 32. Figure 4 This is a cross-sectional view showing a portion of a golf club 10. Figure 3 , Figure 4 The apex direction D1 and the base direction D2 shown are... Figure 1 , Figure 2 Based on.

[0022] The neck 16 is the component that connects the shaft 12 and the clubhead 14. The neck 16 includes an insert 26 and an angle adjustment component 28.

[0023] Insert 26 is a cylindrical component. Insert 26 extends along the length of the rod 12. For example... Figure 3 As shown, the insert 26 includes a first portion 261, a second portion 262, and an annular protrusion 36. The annular protrusion 36 is located near the center along the length of the insert 26. The annular protrusion 36 forms part of each angle adjustment component 28 as described later.

[0024] The first portion 261 of the insert 26 is the portion of the insert 26 on the tip direction D1 side relative to the annular protrusion 36. Therefore, the first portion 261 includes the tip portion 26t of the insert 26. At least a portion of the first portion 261 is inserted into the mounting hole 24 of the aforementioned club head 14.

[0025] A threaded hole (internal thread) 30 is formed in the insert 26. The threaded hole 30 extends from the top end 26t of the insert 26 toward the base end D2. The threaded hole 30 engages with a threaded component (external thread) 32 that is inserted into the mounting hole 24 from the top end D1 side of the club head 14 (see also...). Figure 1 , Figure 2 Thus, the neck 16 is fixed to the clubhead 14.

[0026] The clubhead assembly 42 is formed by fixing the neck 16 to the mounting hole 24 of the clubhead 14. That is, the clubhead assembly 42 is an assembly (structure) having a clubhead 14 and a neck 16 fixed to the mounting hole 24 of the clubhead 14.

[0027] The second portion 262 of the insert 26 is the portion of the insert 26 on the base end side relative to the annular protrusion 36 in the D2 direction. Therefore, the second portion 262 includes the base end portion 26b of the insert 26. The second portion 262 is inserted into the receiving hole 22 of the rod body 12 (see...). Figure 2 ).

[0028] According to this embodiment, at least a portion of the first part 261 is inserted into the mounting hole 24 of the clubhead 14, and the second part 262 is inserted into the receiving hole 22 of the shaft 12. Thus, the clubhead 14 and the shaft 12 are connected via the neck 16. When the insert 26 is inserted into the receiving hole 22 of the shaft 12, the annular protrusion 36 abuts against the tip of the shaft 12, thereby preventing further movement toward the tip of the shaft 12. The annular protrusion 36 positions the relative positions of the neck 16 and the shaft 12 in the longitudinal direction. The second part 262 and the shaft 12 are inseparably joined by an adhesive or the like.

[0029] In this specification, the portion where the shaft 12 and the neck 16 overlap radially is referred to as the connecting portion 34. The shaft 12 is located at the outermost circumference at the connecting portion 34 with the neck 16 (second part 262). Therefore, the shaft 12 becomes the thickest part at the connecting portion 34. Furthermore, the club head 14 and the shaft 12 can be easily separated by removing the threaded part 32 from the threaded hole 30 (mounting hole 24).

[0030] The angle adjustment component 28 is used to adjust the angle of the insert 26 relative to the clubhead 14. The angle adjustment component 28 is located at the top point D1 relative to the top end 12t of the shaft 12 (see reference). Figure 1 , Figure 2 In other words, the rod body 12 is connected to the insert 26 on the side further from the base end in the D2 direction than the angle adjustment member 28. Additionally, at least a portion of the angle adjustment member 28 can also be inserted into the mounting hole 24 together with the second portion 262 of the insert 26. Figure 3 As shown, the angle adjustment component 28 has annular protrusions 36 and multiple annular components 38.

[0031] The annular protrusion 36 is an annular protrusion that projects outward from the insert 26. The annular protrusion 36 bulges out of the insert 26 radially outward. The annular protrusion 36 may also be integrally formed with the insert 26. The annular protrusion 36 may also be formed by joining another component to the insert 26.

[0032] The outer diameter L36 of the annular protrusion 36 and the outer diameter L12 of the shaft 12 are as follows Figure 4 As shown. The outer diameter L36 of the annular protrusion 36 is preferably the same as or smaller than the outer diameter L12 of the shaft 12 (L36 ≤ L12). As an example, the outer diameter L36 of the annular protrusion 36 and the outer diameter L12 of the shaft 12 can also be the same. In this case, the shaft 12 and the annular protrusion 36 at the outermost circumference of the connection portion 34 with the neck 16 are on the same surface. By making the shaft 12 and the annular protrusion 36 on the same surface, the peripheral portion of the neck 141 extends from the shaft 12 with a certain outer diameter, without any steps or bulges. Therefore, the above structure allows for a thinner appearance near the neck 141.

[0033] Multiple annular components 38 are disposed relative to the annular protrusion 36 in the apex direction D1. The multiple annular components 38 are arranged adjacent to each other in the length direction. The multiple annular components 38 surround the outer periphery of the insert 26 (first part 261). The multiple annular components 38 are rotatable about the insert 26.

[0034] like Figure 3 As shown, the plurality of annular members 38 each have a plurality of protrusions and recesses 40. The plurality of protrusions and recesses 40 (the plurality of protrusions) extend from the annular members 38 toward the tip direction D1 and the base direction D2. Adjacent protrusions and recesses 40 in the longitudinal direction can engage with each other. By rotating at least one of the plurality of annular members 38 about the insert 26, the engagement of adjacent protrusions and recesses 40 in the longitudinal direction can be changed.

[0035] Multiple protrusions 40, through changes in their engagement, can adjust the angles of the shaft 12 and the clubhead 14. The angles adjusted by the multiple protrusions 40 can include, for example, the clubface angle, loft angle, and clubhead base angle. By adjusting the angle of the clubhead 14, for example, the direction of the ball's roll can be adjusted according to the golfer's habits.

[0036] like Figure 3 As shown, not only the annular component 38, but also the annular protrusion 36 may have a concave-convex portion 40. By changing the engagement of the concave-convex portion 40 of the annular protrusion 36 and the concave-convex portion 40 of the annular component 38 adjacent to the annular protrusion 36, the angle of the club head 14 relative to the shaft 12 can also be adjusted.

[0037] The outer diameter L38 of the annular component 38 is as follows Figure 4 As shown. The outer diameter L38 of the annular member 38 is preferably the same as the outer diameter L36 of the annular protrusion 36. Thus, the annular member 38 and the annular protrusion 36 become a common surface. As a result, the peripheral portion of the neck 141 forms an outer peripheral surface with the same outer diameter, becoming an elongated shape without steps. Furthermore, since the portion of the annular protrusion 36 of the neck 16 is connected to the connecting portion 34 via an outer peripheral surface with the same outer diameter, the peripheral portion of the neck 141 can be formed into an elongated shape without steps.

[0038] Furthermore, the outer diameter L38 of the annular component 38 and the outer diameter L36 of the annular protrusion 36 can be different. Even in this case, the outer diameter L38 of the annular component 38 and the outer diameter L36 of the annular protrusion 36 are preferably the same as or smaller than the outer diameter L12 of the shaft 12 located at the outermost circumference of the connection portion 34 with the neck 16. In other words, the outer diameter of the angle adjustment component 28 is preferably the same as or smaller than the outer diameter L12 of the shaft 12 located at the outermost circumference of the connection portion 34 with the neck 16. As a result, the peripheral portion of the neck 141 appears thinner.

[0039] The following notes are also disclosed regarding the above-described embodiments.

[0040] (Postscript 1)

[0041] The golf club (10) according to this utility model has: a shaft (12) having a grip (20); a clubhead (14) connected to the shaft; and a neck (16) connecting and fixing the clubhead to the shaft; the clubhead having a mounting hole (24) receiving and holding the neck, the neck having an insert (26) and an angle adjustment member (28) inserted into the shaft and the mounting hole, the angle adjustment member adjusting the angle of the insert relative to the clubhead, the shaft having a receiving hole (22) at the top end (12t) for receiving the insert, the shaft being connected to the insert on a side closer to the base end (D2) than the angle adjustment member, and the shaft being located at the outermost periphery at the connection (34) with the neck. At the junction with the neck, the shaft is located on the outermost periphery, so there are no steps or bulges around the neck of the clubhead. Therefore, the appearance near the neck is tapered.

[0042] (Postscript 2)

[0043] In the golf club described in Appendix 1, the outer diameter of the angle adjustment component is the same as or smaller than the outer diameter (L12) of the shaft. This results in a thinner appearance near the neck.

[0044] (Note 3)

[0045] In the golf club described in Appendix 1 or Appendix 2, the angle adjustment component has: an annular protrusion (36) that bulges radially outward from the insert; and a plurality of annular members (38) arranged relative to the annular protrusion in the apex direction (D1) and surrounding the outer periphery of the insert, wherein the outer diameter (L36) of the annular protrusion and the outer diameter (L38) of the annular members have the same size. Thus, the appearance near the neck becomes thinner.

[0046] (Note 4)

[0047] In the golf club described in Appendix 3, the annular component has a plurality of protrusions and recesses (40) extending toward the tip and the base, respectively. The angle adjustment component adjusts the angle of the clubhead by changing the engagement of the protrusions and recesses of the plurality of annular components. Thus, for example, it is possible to adjust the direction of the ball's roll according to the habits of the golfer making the shot.

[0048] (Note 5)

[0049] According to any one of Appendix 1 to Appendix 4, the mounting hole extends through the clubhead, and the insert is secured to the clubhead from the tip side via a threaded member (32). The clubhead and shaft can be easily separated by removing the threaded member from the threaded hole.

[0050] (Note 6)

[0051] According to the present invention, the neck (16) connects the shaft (12) and clubhead (14) of a golf club (10), and includes: an insert (26) inserted into the clubhead and the shaft; and an angle adjustment member (28) for adjusting the angle of the insert relative to the clubhead, the angle adjustment member having: an annular protrusion (36) bulging radially outward from the insert; and a plurality of annular members (38) arranged relative to the annular protrusion in the apical direction (D1) and surrounding the outer periphery of the insert, the outer diameter (L36) of the annular protrusion and the outer diameter (L38) of the annular members having the same size. Thus, the appearance near the neck of the clubhead becomes thinner.

[0052] (Note 7)

[0053] The clubhead assembly (42) according to this utility model comprises: a neck as described in Appendix 6; and the clubhead having a mounting hole (24), wherein the neck is fixed to the mounting hole. Thus, the appearance near the neck of the clubhead becomes thinner.

[0054] Furthermore, this utility model is not limited to the above disclosure, and various structures may be adopted without departing from the spirit of this disclosure.
