Description

[Detailed description of the invention] (Technical field) The present invention relates to the loft angle and lie angle of a golf club.

Simultaneously measure at least the loft angle and toe rising angle of the seven items: toe top angle, hand first angle, apparent face direction angle, actual face direction angle, and grip end height dimension. This invention relates to a device for comprehensively measuring various angles of golf clubs to be measured.

(Prior Art) Conventionally, when measuring the angle of a golf club, the loft angle and lie angle were measured separately. Loft was measured by leaning the club against a wall and placing a commercially available level meter on the club's hitting surface.

The lie angle was measured by using a commercially available protractor to measure the angle between the sole and the just. This method has problems because the measurement results are unstable. Another method is to use a loft meter equipped with a club angle correction machine and a lie needle, but in any case, conventionally only two things were measured: loft angle and lie angle. has the biggest problem.

As the shaft of a golf club becomes longer and the loft increases, it is preferable that the hitting surface of the golf club be oriented slightly to the left with respect to the flight line. The longer the shaft, the greater its bend, and the hitting surface tends to point to the right in relation to the flight line. In addition, when the ball hits the hitting surface, the shaft tends to lead and the hitting surface lags behind, causing it to turn further to the right. It's easy to get into a situation where you can't grip the ball.

Therefore, the apparent direction of the batting surface is at right angles to the fly ball line, and the leading edge of the C batting surface is at right angles.) When the toe is lifted, the actual direction of the batting surface is to the left. 9 irons and pitching wedges have short shafts and large loft angles, so they bend less, and the loft angles are large, so they don't crush the ball too much, so the direction of the hitting surface is
Even if you aim for impact, it won't open as much as a wood club or long iron. Furthermore, as the loft angle increases, the difference between the apparent direction of the hitting surface and the actual direction of the hitting surface increases. If a long iron and a short iron are lifted by the same angle, the short iron is more likely to hit the ball to the left for the reason mentioned above. In this case, if you hit with an open hitting surface, the ball will fly straight to the intended flight line, but even though the loft angle is too steep and you have a 9-iron, its performance is comparable to that of a pitching wedge. It's the same thing as hitting a 9-iron with a sand wedge.You won't be able to bring out the true performance of your 9-iron. Since inexperienced golfers are swinging with a 9-iron, they often see the high trajectory and think that their swing is bad. Although the loft angle and the toe angle are closely and inseparably related, conventionally they have not been measured at the same time.

(Purpose) The present invention is intended to determine, when a person holds a certain club, whether or not the club conforms to the person's ideal swing, or to what extent various angles need to be corrected. The purpose is to accurately measure various angles simultaneously and comprehensively in order to determine the

(Structure) In order to achieve the above-mentioned object, the present invention attaches a shaft to a base, and attaches a rocking body that can swing around an axis that intersects the shaft to a frame that can swing around the shaft, A club holding member is provided on the rocking body, and a rotation angle detecting member for the frame body and the rocking body is provided. It is something. This will be explained in detail below based on examples. Reference numeral 1 denotes a base that can be horizontally rotated around a central axis IC, and side members 1a are fixedly protruding upward from both ends.

Next, a method of using the device of the present invention will be explained.

The iron club 17 is fixed to the iron club holding member 7 so that the horizontal stripes on the loft surface are horizontal, and the lower protrusion 7i is fitted into the long groove 5C of the swinging body 5.

Then, a person grips a 9-iron club 17 on the fixed base 14 and holds it according to the person's habit. The base 1 rotates horizontally around the axis IC, the frame 3 swings toward the front layer around the horizontal shafts 2a and 2b, and the rocking body 5 swings left and right around the horizontal shafts 4a and 4b. However, the iron club 17 is held in a stance appropriate to the person's habits. At that time, the loft angle is detected by reading the inclination of the loft angle pointer 9 with the loft angle scale plate 10, and the lie angle measurement frame 8 is brought into rotational contact with the iron club 17Vc, and the toe angle and lie angle scale plate 18 are read. Detecting the lie angle and reading the inclination of the toe angle pointer 11 using the toe rising angle and lie angle scale plate 12 to detect the toe angle,
The hand first angle can be detected by the iron club 17 and the hand boost angle scale 13, and the direction of the club ace can be detected by the pointer 7h and the hitting surface direction scale plate 15.

In the case of a wood club, it is held and fixed to the wood club holding member 6, and each angle is measured with the wood club held in the same manner as in the case of the iron club.

In addition, cases in which the golf club holding member is directly fixed to the rocking body, cases in which the loft angle, toe rising angle, etc. are measured by other means, and cases in which the golf club is attached to the golf club holding member by other means. It's okay.

(Effects) According to the present invention, a shaft is attached to a base, a swinging body capable of swinging around an axis perpendicular to the shaft is attached to a frame that can swing around the shaft, and a club is attached to the swinging body. A holding member is provided,
Since the rotation angle detection member of the frame body and the swinging body is provided, the loft angle and the toe rising angle can be simultaneously and comprehensively and accurately measured while the golf club is being held according to the person's habit.
