The shaft centerline 29 is now horizontal, ie parallel to the rods 12,12.

Next, lower the ruler plate 44 and attach the leading edge 49 to the head face surface.
While hitting the sole 50 of the head with the sole 33 of the head against the surface of the sole contact plate 31, the sole contact plate 31 is rotated and the head base 39 is moved up and down so that the leading edge 49 does not make a gap at the end. Score line 6 on face 50, which is in contact with face 50
Adjust so that it is parallel to 4, ... By doing so, the surface of the sole contact plate 31 coincides with the ground surface to which the sole 33 should contact. Therefore, at this time, the axis of the vertical axis 34 passes through the intersection of the center line of the shaft and the ground surface to which the sole contacts. The index 37 shows the lie angle of the club 26 on the lie angle scale 38. If the lie angle is known, the index
The operation can be simplified by adjusting the lie angle of 37 and tightening the tightening screw 35 to fix the sole contact plate 31, and the above adjustment is only the vertical movement of the head base 39.

The tip edge 49 of the ruler plate does not cover all of the score lines 64, ... And the closer to the sole contact plate 31, the easier it is to make the above adjustment, so loosen the set screw 48,
Adjust the position of the tip edge. This position adjustment
It is not very strict, so it is not necessary for all measurements and may be done as needed.

The above adjustment using the ruler plate is performed for the iron club, and is not applicable to the wood club. In wood clubs, the face surface is usually convex,
This is because the score line is not parallel to the ground surface that the sole should touch. For wood clubs, without using a ruler plate, the surface of the sole contact plate 31 and its upper edge 36 are compared with the sole and face surface of the head, and the horizontal direction of the plane contacting the center of the face surface and the upper edge 36 are parallel. Then, the sole contact plate 31 is rotated and the head base 39 is moved up and down for adjustment so that the ground surface to be contacted by the sole coincides with the surface of the sole contact plate 31. Therefore, the ruler plate can be omitted by using the measuring device dedicated to the wood club.

Next, move the moving table 52 and place the top pad 54 on top.
Abut on 59. Then, the movable table 52 is slightly moved, and the dial 55 is operated to rotate the adjusting screw 56 so that the rear end 60 of the grip 58 is aligned with the reference position 61 in this contact state.

The index 62 then indicates the length of the club on the length scale 30.

Since the shape of the top 59 is usually the same within one type of club, when sequentially measuring one type of club, it is sufficient to simply move the moving table and bring it into contact with the top. It is not necessary to operate the adjusting screw 56.

EFFECTS OF THE INVENTION Since the head side positioning device of the present invention rotates the sole contact plate by the vertical axis intersecting the horizontally extending shaft center line, the head is moved by the rotation of the sole contact plate and the vertical movement of the head base. The sole axis of the sole plate so that the vertical axis of the sole plate passes through the intersection of the ground surface that the sole should touch and the center line of the shaft.
The golf club can be positioned.

In particular, when the ruler plate is provided, the operation of correctly applying the head to the sole contact plate can be performed easily and accurately.

Since the grip side positioning device of the present invention is provided with the top backing plate at a position slightly retracted from the reference position provided on the moving base, and the top is brought into contact with the top backing plate, the position of the top backing plate If you adjust the position according to the shape of the top, you can easily and accurately determine the rear end position of the grip simply by moving the moving table and applying it to the top of the grip.

The length measuring device of the present invention is the head side positioning device,
Since the grip side positioning device is used, both ends of the length to be measured can be easily determined, and the accurate length can be measured. Moreover, since the part near the head of the shaft where the shape of the club is almost the same is supported by the fixed fixed shaft stand and the middle part is supported by the movable movable shaft stand, it can be used for various clubs. it can.
