Description

  The present invention relates to a method of measuring a loft (hereinafter referred to as “impact loft”) and a face orientation (hereinafter referred to as “impact face orientation”) when actually hitting a ball in golf, and particularly in putting. It is suitable for measuring the impact loft and impact face.

  In golf, there are lofts and face orientations as golf club specifications. This indicates the direction in which the face that is the striking face faces when the golf club head is placed on the turf or floor and the golf club is in a predetermined posture. The angle at which the face deviates left and right on the horizontal plane from the intended hitting direction is called the face direction.

  In actual play, since each golfer has a different swing, there are many cases where the ball is not hit with the predetermined posture, and it is rare that the golf ball is impacted in the loft or face direction as the specifications of the golf club. Therefore, it is possible to select a golf club having a more appropriate specification by measuring the impact loft and the impact face direction indicating the direction in which the face is facing at the moment of impact when actually hitting the ball. Become.

  Many methods for measuring impact lofts and the like have been proposed for a long time, such as optical ones and magnetic ones. However, in recent years, there has been a problem that the apparatus becomes large (see, for example, Patent Document 1). A method of doing this very simply using a golf club dedicated to measurement is also being proposed (see, for example, Patent Document 2).

JP 2004-195240 A JP-A-8-238339

  However, since the measurement method described in Patent Document 2 uses a golf club dedicated to measurement, it is difficult to determine whether the same data as when the ball was actually hit is obtained. This is because golf clubs have many specification items such as length, weight, and balance in addition to the loft and face orientation, and if any of them is different, there is a possibility that the impact loft or impact face orientation will change.

  In view of such circumstances, the present invention is intended to provide an impact loft or impact face orientation measuring means that can freely select a golf club to be used for measurement, and that is simple and excellent in portability.

The present invention
An instrument that measures the impact loft and the impact face direction indicating the direction of the face when the golfer hits the golf ball,
It has a hit surface consisting of a curved surface,
The hit surface has a collision position recording means that leaves a collision mark when it collides with the face surface of a golf club,
A golf swing measuring instrument characterized in that a scale for reading at least one of an impact loft and an impact face direction from the collision mark is attached to the hit surface or the vicinity thereof.

  The hit surface is convex toward the side on which the golf club collides, and it does not have an inflection point in order to collide with the face surface of the golf club at one point. In order to make it more similar to a golf ball and considering the ease of measurement and accuracy, it is preferable that the radius of curvature of the hit surface is constant. Specifically explaining the shape of the hit surface, when measuring the impact loft, it is desirable that it is an arc having a radius in the vertical direction, and when measuring the impact face direction, it is preferably an arc having a radius in the horizontal direction. When measuring both the impact loft and the impact face direction, a spherical surface is desirable. It is also preferable to provide a mark indicating the center of the hit surface.

  Increasing the radius of curvature of the hit surface is preferable because the difference becomes clear even when the angle is the same. However, if the curvature deformation is made too large and approaches a flat surface, the collision mark becomes large and the measurement accuracy may be lowered. According to the studies by the inventors, a radius of curvature of about 50 to 65 mm is appropriate. Particularly, when the radius is 57.3 mm, the difference between the impact loft or the impact face direction is about 1 mm, and the scale can be easily manufactured.

  It is more preferable that the hit surface is vertical at a position of 21 mm ± 5 mm from the bottom surface. The vertical position of 21mm ± 5mm from the bottom means that the normal vector of the plane that touches the point is defined at all points on the hit surface. It means the position of 21mm ± 5mm from the height. Since the radius of the golf ball is approximately 21 mm, the bottom or 21 mm position is vertical, and by making the hit surface of the inventive product the same extent as this, it is possible to measure close to actual hitting is there.

  Since the collision position recording means is for reading the scale of the hit position, the method is not particularly limited, but a method of sticking pressure-sensitive paper, a method of leaving marks by applying powder or paint, etc. Etc. are simple.

  The operation of the inventive device will be described. The device according to the present invention is used by hitting a hitting surface with a golf club just like a golf ball. Since the hit surface is a curved surface, if the impact loft or impact face direction is different, the position of collision with the face surface of the golf club will be different. The position is recorded as a collision mark. Since a scale is attached to the hit surface or the vicinity thereof, at least one of the impact loft and the impact face direction can be measured by reading the scale corresponding to the position of the collision mark.

  The product of the present invention is used by hitting with a golf club after being installed on a horizontal surface, and it is necessary to have an installation means so that the scale always has a correct angle at the time of installation. Specifically, the bottom surface in contact with the floor may be a horizontal surface, or multiple surfaces may be in contact with the floor, but if the device of the present invention can always be installed in the same posture, concrete means Is not limited.

  According to the golf swing measuring instrument of the present invention, it is possible to achieve an excellent effect that it is possible to easily measure the impact loft and the impact face direction indicating the face direction at the moment when the golfer hits the golf ball.

The figure which shows the case where it actually measures in Example 5 shown in FIGS.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  1 is a perspective view of the first embodiment, and FIG. 2 is a side view of the first embodiment. The hit surface 1 of the present embodiment is an arc having a radius in the vertical direction, and it is possible to measure only the impact loft.

  The hit surface 1 is hit with a golf club and used as shown in FIG. FIG. 3 shows the moment of hitting, that is, the moment of impact between the hit surface 1 and the golf club head 5. Due to this collision, as shown in FIG. 4, a collision mark 4 remains in the collision position recording means 3 of the hit surface 1, but the hit surface 1 which is a curved surface is tangent to the face surface 6 of the golf club head 5 at the time of the collision. Collide at the same position. Therefore, the impact loft can be measured by reading the scale 2 corresponding to the position of the collision mark 4.

  Example 1 is configured by attaching a portion having a hit surface 1 and a scale 2 to a golf ball. Of course, even if there is no golf ball and only the portion having the hit surface 1 and the scale 2 is self-supporting and capable of being hit, it functions sufficiently.

  In this embodiment, pressure sensitive paper is pasted on the hit surface 1 as the collision position recording means. Since pressure sensitive paper for measuring the hitting position with a name such as a shot marker is commercially available as one of golf equipment, it is easy to use this. As long as the collision marks remain, such as applying powder, the replacement with other means is not limited.

  FIGS. 5 to 6 show a second embodiment of the invention for measuring the same impact loft as in the first embodiment.

  The present embodiment is different from the first embodiment in that the reference line 7 is provided in the ball-shaped portion and that the hit surface 1 has a slight curvature in the horizontal direction. Since the reference line 7 is drawn in a direction perpendicular to the direction in which the ball is rolled, the person to be measured can clearly recognize the striking direction. Since the hit surface 1 is a curved surface having a slight curvature in the horizontal direction, a clear collision mark is likely to be made even if the impact face direction slightly deviates from 0 degrees. When the hitting surface 1 does not have a curvature in the horizontal direction as in the first embodiment, that is, when the hitting surface 1 is flat in the horizontal direction, if the face collides with a large left-right collision, an oblique collision occurs. This is because a collision mark is made only at the end of the surface 1 and it is difficult to read the scale accurately.

  7 to 9 show a third embodiment of the invention, which is used for measuring the impact face direction.

  In this embodiment, the hitting surface 1 and scale 2 of Example 2 are turned 90 degrees, and the radial direction of the hitting surface 1 is the horizontal direction, which matches the face direction at the time of impact. A collision mark remains at a position on the hit surface 1 to be measured, and thereby the direction of the impact face is measured.

  Just as Example 2 has a slight curvature in the horizontal direction, this example has a slight curvature in the vertical direction. As a result, a clear collision mark is obtained regardless of the impact loft, and the measurement accuracy is ensured.

  Further, in this embodiment, the reference line 7 is drawn in the hitting direction and the direction perpendicular thereto. This is to make the person to be measured clearly recognize the striking direction as in the second embodiment.

  Further, in this embodiment, the portion having the hit surface 1 and the scale 2 extends in the horizontal direction and does not contact the floor, so the foot 8 is necessary. Thereby, when placed on a floor or the like, the hit surface 1 always has the same posture.

  10 to 12 show a fourth embodiment of the invention, which can measure both the impact loft and the impact face direction at the same time.

  Since the hit surface 1 is a part of a spherical surface, it collides with the face surface at a portion where the normal direction coincides. Since the scale 2 is marked on the hit surface 1, both the impact loft and the impact face direction can be measured simultaneously.

  The collision position recording means in the present embodiment is preferably a method of applying powder or the like to the hit surface 1. This is because, unlike the first to third embodiments, the scale 2 is on the hit surface 1, and thus the scale is difficult to read if pressure-sensitive paper is pasted on the hit surface 1. Alternatively, a method of placing the scale 2 on the pressure sensitive paper is also conceivable. In that case, a means for making the position where the pressure-sensitive paper is stuck constant is necessary. In this embodiment, the foot 8 is required as in the third embodiment.

  13 to 20 show a fifth embodiment of the invention. Like the fourth embodiment, FIG. 13 to FIG. 20 have a hitting surface 1 made of a part of a spherical surface, and a scale 2 is marked on the hitting surface 1. Both impact loft and impact face orientation can be measured simultaneously.

  This embodiment has a foot 8 extending in the horizontal direction. If the foot 8 is formed in a U-shape that opens in the striking direction as shown in FIG. 14, the golf ball 9 as shown in FIGS. Can also be used. As a result, measurement in a state closer to actual hitting becomes possible.

  Further, as shown in FIGS. 16 to 18, when the ball 9 is placed in contact with the back surface of the hit surface 1, a clearer collision mark can be obtained.

  19 to 20 show a case where measurement is actually performed in the fifth embodiment. FIG. 19 shows a case where a golf ball is hit with a putter type golf club, and shows a moment when the golf club head 5 collides with the hit surface 1. Due to this collision, a collision mark 4 remains on the contacted surface 1 on which the collision position recording means is applied. FIG. 20 shows this state.

  The scale 2 of this embodiment shown in FIG. 20 is such that the small circle at the center indicates 0 degrees in both the impact loft and the impact face direction, and each line is drawn at a pitch of 2 degrees. From the position, the impact loft is 5 degrees and the impact face direction is right (so-called open) 2 degrees. It should be noted that the graduation method, the pitch, and the like are not limited to the state of the present embodiment.

  The golf swing measuring instrument of the present invention can be used for so-called golf club fitting, which measures a golf swing and searches for a golf club specification suitable for each golfer.
