Then, the loft gauge plate 134 and the ligage plate 137 which can be moved to arbitrary positions are moved, and the ligature plate 137 and the lie angle scale indicating plate 142 are adjusted so as to abut the shaft of the golf club to adjust the loft angle and the lie angle. Was being measured.

Further, in another conventional example, Japanese Patent Publication No. 3-690.
The "simultaneous various angle measuring device for golf clubs" described in Japanese Patent No. 41 is known. As shown in FIGS. 8 and 9, the “simultaneous angle measuring apparatus for golf clubs” is configured such that the intermediate portions of both sides of the frame body 203 are pivotally attached to the shafts 202a and 202b on both sides of the base 201 so as to be vertically swingable. Shafts 204a, 2 orthogonal to the swing shafts 202a, 202b are provided in an outer middle portion of the frame 203.

[0004]

However, in the conventional measuring device, it is necessary to fix the club head of the golf club and measure the angle with reference to the club head, and the measuring device becomes large and easy to carry. , It was not a simple type that could be easily measured. Further, since the relative positional relationship between the measuring device and the golf club is adjusted to the measuring device with reference to the position of the head, which is a very small portion of the entire club, the initial positioning is not easy.

While the shaft locking portion 2 is locked to the shaft B, the head arm 3 is rotated around the lie angle rotation shaft 24 to the position of the club head C, moved to the position above the head C, and further moved to the lie angle rotation. The sole E is brought into contact with the sole contact plate 43 of the head contact portion 4 by sliding the movable shaft 24 in the axial direction.
Next, the face contact plate 41 is rotated about the rotation shaft 42 and brought into close contact with the face D. The scoring line F engraved on the face D can be confirmed through the face contact plate 41 because the face contact plate 41 has a light-transmitting property. At this stage, the scoring line F and the face contact plate 4
Parallel line 44 of 1 is not parallel, so parallel line 4
4 and the scoring line F are parallel to each other, the shaft locking portion 2 is moved to the grip side or the head side while being in close contact with the club A, and the head arm is contacted while the sole E and the sole contact plate 43 are brought into contact with each other. 3 is rotated to make the scoring line F parallel to the parallel line 44. With the face F and the parallel line 44 parallel to each other in this way, the grip side locking portion 21 and the head side locking portion 22 of the shaft locking portion 2 are locked to the shaft, and the face contact plate When 41 is brought into close contact with the face D and the sole E is brought into contact with the sole contact plate 43, the setting of the club A on the measuring instrument 1 is completed. When the setting of the club A is completed, the scale 52 indicated by the instruction line 52 of the face progression display section 5 is read and the face progression amount Y is measured. Next, the pointer 61 of the lie angle display section 6
The scale 62 indicated by is read and the lie angle α is measured. Similarly, the loft angle β is measured by reading the scale 72 indicated by the pointer 71 of the loft angle indicating section 7.

[0017]

EFFECTS OF THE INVENTION With the above configuration, the shaft locking portion is attached along the shaft, and the scoring line engraved on the face of the club head and the parallel line attached to the face contact portion are parallel to each other. By doing so, the relative measurement positions of the club and the measuring device are determined, so the size of the measuring device itself does not become large, and the measuring device can be a portable golf club that is not stationary. . Further, since the initial measurement positions of the measuring device and the golf club are determined by the large distance of the shaft occupying most of the golf club, accurate position determination can be performed relatively easily.
