DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf club and a golf club set, and more particularly, to a shaft in which the invention is devised.

[0002]

2. Description of the Related Art Conventionally, when setting a club head close to a ball that rests on the ground in order to hit a golf ball, the orientation of the face with respect to the target direction in which the ball flies has to be checked through the arm of the player. The face of the head disposed at the tip of the head is viewed from above. In this case, since the position of the held face is considerably far from the eyes of the player, conventionally, a white line marking line is provided at the lower end of the face surface in the length direction of the face, or the head portion is provided. There is a commercially available product in which a mark is provided on the head portion to facilitate confirmation of the posture of the face from above by providing a white marking line in the length direction of the face on the upper crown, or the like.

[0003]

However, since the conventional marker line is provided exclusively in the head portion, it is short and thin, and in addition to being worn or stained during use of the club. In particular, when the above-mentioned marking line is provided on the face surface, in a wood club called a driver, the position of the face is considerably left forward (right-handed) depending on how the head is held. In some cases, the marker line can hardly be confirmed because the object is moved to ()).

Accordingly, an object of the present invention is to provide a golf club and a set thereof in which the attitude of a face of a club head, particularly the inclination of the face, can be easily confirmed when the player is hitting a ball.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a golf club having a head provided at one end of a shaft for hitting a golf ball and a grip provided at the other end of the shaft. In the golf club of the present invention, a linear portion extending in the axial direction is formed on at least a part of the outer peripheral surface of the shaft seen by the player at the time of addressing.
Further, in a golf club set comprising a plurality of wood clubs or iron clubs of various counts or a combination of both, an axial linear portion is formed on at least a portion of the shaft outer peripheral surface seen by a player at the time of addressing, and the linear portion is formed. Are appropriately inclined with respect to the axis in accordance with the club characteristics of each count.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings.

The embodiment shown in FIG. 1 is an overhead view of a wood club in which one end of a shaft 1 is inserted and fixed to a hosel 3 of a head 2 and a grip 5 is provided at the other end. A linear portion 6 extending in the axial direction of the shaft 1 is formed on the outer peripheral surface seen by a player when the shaft 1 is addressed. The straight portion 6 is parallel to the face surface 4 of the head 2 and is formed over the entire visible range of the shaft 1. The straight portion 6 is formed from approximately the center of the shaft width at the hosel 3 of the shaft 1 to approximately the center of the shaft width at the grip 5. In this embodiment, a first colored portion 7 (for example, red) and a second colored portion 8 (for example, yellow) of different colors are provided on the left and right of the linear portion 6. The straight portion 6 is a boundary between the first and second colored portions 7 and 8.

In the embodiment shown in FIG. 1, the distance from the head 2 to the mouth end of the hosel 3 is 40 mm, the length of the grip 5 is 280 mm,
The length of the two colored portions of the shaft 1 was 790 mm. The first and second colored portions 7 and 8 are also applied to the outer peripheral surface on the back side of the shaft 1 in FIG. 1 and have the same boundary line.

In another embodiment shown in FIG. 2, the straight portion 6 is not formed over the entire visible range of the shaft 1 at the time of addressing, but is formed near the hosel 3 and the grip 5, and formed at an intermediate portion of the shaft 1. Indicates what has not been done. The lengths of the first and second colored portions 7, 8 in this example were 100 mm and 150 mm, respectively.

Another embodiment shown in FIG. 3 is that a straight portion 6 and first and second colored portions 7,
8 was formed. The length of this part was 200 mm.

[0011] When the player makes a right-handed strike, the head 2 is placed at the left side from the center line of the body, and the clubs up to No. 5 of the wood club or the iron club are group I, and the head is placed at the center of the body. When the iron clubs and putters Nos. 6 and 7 are group II, the heads are placed on the right side from the center line of the body and the Nos. 8-9, and PW and SW are classified into three groups as group III. As shown in FIGS. 4 and 5, the shaft 1 of the club has a negative inclination angle with respect to the axis y of the shaft 1 on the outer peripheral surface from the mouth end of the hosel 3 to the start end of the grip 5. A boundary line, that is, a straight line portion 6 is drawn, and outer half peripheral surfaces of the left and right shafts 1 on the boundary line are colored red or yellow, respectively, to form first and second colored portions 7, 8.
It has been.

As shown in FIG. 6, each club of Group II has a straight line extending from substantially the center of the width of the shaft 1 at the mouth end of the hosel 3 to substantially the center of the width of the shaft 1 at the start end of the grip 5. Is drawn substantially parallel to the leading edge 4A of the face 4, and the outer half surfaces of the left and right shafts 1 are colored red or yellow, respectively, as a straight line portion 6, so that the first and second colored portions 7, 8 are formed. It has been.

Further, as shown in FIG. 7, each club of the group III is provided on the outer peripheral surface between the mouth end of the hosel 3 and the start end of the grip 5 on the positive side with respect to the axis y of the shaft 1. A boundary line (straight line portion 6) is drawn on the inclined surface,
The outer half circumferential surfaces of the left and right shafts 1 on the boundary are colored red or yellow, respectively, to form first and second colored portions 7 and 8.

As a golf club set, there is a set including only a plurality of wood clubs, a set including only a plurality of iron clubs, and further, for example, wood clubs No. 1, No. 3 and No. 4 and Nos. 3 to 9 No., PW (pitting wedge) and SW (sand wedge) iron clubs are available. Alternatively, if a set of 9 to 10 iron clubs is a full set, there is a set called a so-called half set of about 5 to 6 pieces. The golf club set of the present invention is applicable to any set.

In hitting a golf ball, when a player holds both legs open, when a golf club or a long iron club having a long club length is used, the face 4 of the head 2 is located on the left side of the center line of the body. In a short iron club that is placed and has a short club length, the face 4 is usually placed on the right side of the center line of the body (right-handed). Therefore, the axis y of the shaft 1 of each club is set at a slightly different inclination angle with respect to the target direction. In consideration of this point, in the golf club set according to the present invention, in the group of woods and long irons having a small number, the straight portion 6 is inclined rightward on the tip side of the shaft 1 with respect to the axis y of the shaft 1. On the other hand, in the group of short irons having a large iron count, the inclination of the straight portion 6 at the tip end side of the shaft 1 is inclined to the left to the contrary, and in the group of middle irons having a middle iron count and the putter club, ,
The two colors to be colored on the shaft 1 are arranged in different colors on the outer peripheral surface of the shaft 1 for each of the above-mentioned groups so as to be parallel to the leading edge 4A of the face 4 to form a set. I have. Also, in this case,
It is also possible to finely change the inclination angle of the boundary line with respect to the axis y of the shaft 1 for each club of each count. The inclination angle formed by the axis y of the shaft 1 and the linear portion 6 is, as shown in FIG. 4, FIG. 5 or FIG. 7, a bird's-eye view of the club shaft at the time of address, and the shaft 1 at the mouth end of the hosel 3. The angle formed by the oblique line extending from the left corner (or right corner) of the grip 5 to the right corner (or left corner) of the shaft 1 at the start end of the grip 5 and the axis is a plus side (or a minus side).
Is the maximum value.

Further, in another embodiment shown in FIGS. 8 and 9, the linear portions 6 are provided on both side ends 9 of the outer peripheral surface of the shaft, and the entire surface of at least a part of the outer peripheral surface of the shaft in the axial direction is provided. Is the first colored portion 7, the entire surface of the outer peripheral surface of the shaft which is not visible to the player at the time of addressing is defined as the second colored portion 8, and the linear portion 6 is defined as the first and second colored portions. It can be a boundary line.

The color of the shaft 1 is appropriately combined with red, yellow, orange, white and the like, which are conspicuous. In addition, the coloring method is performed using an existing method such as jet painting of paint or pasting of a color printing sheet.

[0018]

As described above, in the golf club according to the present invention, a linear portion extending in the axial direction is formed on at least a part of the outer peripheral surface of the shaft seen by the player at the time of addressing, and the left and right shaft peripheral surfaces are formed. Since the two colors are used, when the golf ball is hit at an address (that is, the stance), the orientation of the face with respect to the target direction is changed by the inclination of the linear portion of the outer peripheral surface of the shaft fixed to the head portion having the face. Alternatively, the adjustment can be performed accurately and easily using the change in the width of each of the two colors as a guide. For example, if the linear portion is formed parallel to the shaft axis and the face is too left (right-handed) with respect to the target direction at the time of addressing to form a so-called hook face, The width of the color on the left side of the outer peripheral surface with respect to the part is reduced and becomes invisible, while the width of the color on the right side is increased and becomes visible. Therefore, in this case, in order to set the direction of the face at right angles to the target direction, the direction of the face may be changed until the color width of the left and right portions looks almost the same. In addition, when the face is set so as to cover the ground excessively, the linear portion appears to be strongly inclined with respect to the target direction. Adjust the stance so as to reduce the inclination of.

In the case where the first and second colored portions of different colors are provided on the left and right sides of the linear portion, when the golf ball is hit, the face of the head portion, which becomes the hitting surface, has a desired posture with respect to the target direction. It is easier to judge the correctness of the posture when setting the position.

In the golf club set of the present invention,
By changing the inclination angle of the linear portion with respect to the axis of the shaft according to the characteristics of the clubs for each count, the width of the two colors on the outer peripheral surface of the linear portion and the shaft at the time of addressing for all the clubs in the set is improved. The face can be clearly checked, and the orientation of the face is adjusted by observing the difference from the preset inclination angle and color width.
