Description

  The present invention relates to a swing weight measuring device for measuring a swing weight of a golf club, and a golf club set including a plurality of golf clubs in which swing weights measured by the swing weight measuring device are set substantially the same.

  In a golf club, a swing weight (also referred to as a swing balance) is measured as an index of the weight and ease of swinging of a golf club that a golfer feels when swinging.

  The swing weight can be regarded as a rotational moment around a fulcrum when the golf club is swung. Conventionally, it is common to measure the rotational moment with a 14 inch (35.56 cm) part from the grip end as a fulcrum, but it measures with a 12 inch (30.48 cm) part as a fulcrum, and 5 inches ( There is also a device that measures a site of 12.7 cm) as a fulcrum (see Patent Document 1).

  FIG. 2 is a schematic configuration diagram of the swing weight measuring instrument 2 that measures the rotational moment with a portion 14 inches from the grip end as a fulcrum.

  In the swing weight measuring instrument 2, a support member 6 is disposed on a base 4, and a rod 8 is pivotally supported on the support member 6 so as to be rotatable. A club support portion 14 that supports the shaft 12 of the golf club 10 from below is disposed at one end of the rod 8. A grip end holding portion 18 that holds the grip end 16 of the golf club 10 is disposed at a predetermined portion between the other end portion of the rod 8 and the support member 6. In this case, the distance between the grip end holding portion 18 and the support member 6 is set to 14 inches. A weight 20 slidable along the rod 8 is disposed between the grip end holding portion 18 and the support member 6. In the movable range of the weight 20 of the rod 8, a scale 22 representing a swing weight (for example, a combination of numerical values with alphabets C to E) is recorded. Note that the upper and lower swing ranges of the other end of the rod 8 are restricted by a restricting member 24 disposed on the base 4.

  In the swing weight measuring device 2 configured as described above, the rotational moment about the fulcrum P at the center of gravity G of the golf club 10 is maintained by adjusting the position of the weight 20 with respect to the rod 8 and holding the golf club 10 in a horizontal state. And the rotational moment around the fulcrum P at the grip end 16 is balanced. The fulcrum P is a point on the fulcrum Q that is the center of rotation of the rod 8.

  In this case, if the weight of the golf club 10 is W (ounces) and the distance between the fulcrum Q of the support member 6 and the center of gravity G is L (inch), the swing weight is L · W, and this corresponds to L · W. Then, the swing weight is measured by reading the set value of the scale 22 from the position of the weight 20.

JP 2004-325145 A

  By the way, for example, in an iron club set, a process of adjusting the weight and the like of the head 26 is performed so that the swing weights of the golf clubs constituting the set are the same. Thereby, it is supposed that it is possible to make the swing sense in each golf club the same.

  However, when the length and weight of the golf club are greatly different, the swing feeling may be different even if the swing weight is adjusted to be the same.

  As a reason for this, in the swing weight measuring device 2, it is conceivable that the swing fulcrum P of the golf club 10 is set at a point 14 inches from the grip end 16. The actual swing point P of the golf club 10 is located closer to the grip end 16, and in particular, the putter fulcrum P is further closer to the grip end 16.

  The present invention has been made in view of the above problems, and an object thereof is to provide a swing weight measuring instrument capable of measuring an appropriate swing weight corresponding to the actual swing feeling of a golf club.

  It is another object of the present invention to provide an appropriate golf club set that can obtain an equivalent swing feeling.

The swing weight measuring instrument of the present invention is a swing weight measuring instrument for measuring a swing weight of a golf club.
A grip end holding portion for holding the grip end;
A club support that supports a predetermined portion between the grip end and the head from below;
A rod on which the grip end holding portion and the club support portion are connected, and a predetermined portion in a range of 2.5 to 10 cm on the club support portion side from the grip end holding portion is pivotally supported;
A weight slidably mounted on the rod extending in the opposite direction to the club support portion from the grip end holding portion;
The swing weight is measured based on the position of the weight when the rod is in a horizontal state.

  The swing weight measured by the swing weight measuring device includes a plurality of the golf clubs set to be substantially the same.

  With the swing weight measuring instrument of the present invention, the swing weight can be measured with reference to the vicinity of the actual fulcrum position of the golf club swing, so that a swing weight that is an index that matches the sense of swing with high accuracy can be obtained. .

  In addition, by setting golf clubs having substantially the same swing weight as described above as a set, it is possible to provide a golf club set with an equivalent swing feeling.

  In particular, in the putter, since the fulcrum during the stroke is very close to the grip end, a more appropriate swing weight can be obtained.

  FIG. 1 is a side configuration diagram of a swing weight measuring instrument 30 of the present embodiment.

  In the swing weight measuring device 30, a support member 34 is disposed on a base 32, and a rod 36 is pivotally supported with respect to a fulcrum Q of the support member 34. At one end portion of the rod 36, a club support portion 42 for supporting a shaft 40 of a golf club 38 having a putter head 37 from below is disposed. Further, a grip end holding portion 46 that holds the grip end 44 of the golf club 38 is disposed on the opposite side of the support member 34 from the club support portion 42. In this case, the distance between the support member 34 and the portion where the grip end holding portion 46 is disposed is set to 1 inch.

  The rod 36 extends further from the portion where the grip end holding portion 46 is disposed to the other end side, and a weight 48 slidable along the rod 36 is disposed in the extending portion. Is done. A scale 50 representing the swing weight of the golf club 38 is recorded in the movable range of the weight 48. Note that the other end portion side of the rod 36 is loosely fitted to a restriction member 52 disposed on the base 32, and the vertical swing range of the rod 36 relative to the base 32 is restricted.

  The swing weight measuring instrument 30 according to the present embodiment is basically configured as described above, and next, its operation and effects will be described.

  The shaft 40 of the golf club 38 is supported by the club support portion 42 and the grip end 44 is held by the grip end holding portion 46, and then the weight 48 is moved along the rod 36 to set the golf club 38 in a horizontal state. To do. At this time, the rotational moment L · W around the fulcrum P at the center of gravity G of the golf club 38 is balanced with the rotational moment around the fulcrum P at the grip end 44, and the swing weight corresponding to this rotational moment corresponds to the position of the weight 48. It is measured as the value of the scale 50 to be performed.

  In this case, since the measured swing weight is a swing weight at the fulcrum P that substantially coincides with the center of the stroke of the putter golf club 38, a measurement result very close to an actual stroke feeling can be obtained. Therefore, the golfer can select a putter composed of his / her desired swing weight or adjust a weight of the head 37 to obtain a putter composed of a desired swing weight.

  In the above-described embodiment, the case where the distance between the support member 34 and the grip end holding portion 46 is set to 1 inch (2.54 cm) has been described, but this distance is set to approximately 1 inch to approximately 4 inches (2. By adjusting within a range of 5 to 10 cm), it is possible to measure an appropriate swing weight according to the type of golf club to be applied.

  Next, the golf club set of this embodiment will be described.

  Golf club sets A, B, and C composed of four different putters having shaft lengths of 32 inches, 33 inches, 34 inches, and 35 inches are created, and swing weights of the golf club sets A, B, and C are created. Measurement is performed using the conventional swing weight measuring instrument 2 (also referred to as a 14-inch measuring instrument) shown in FIG. 2 and the swing weight measuring instrument 30 (also referred to as a one-inch measuring instrument) according to the present embodiment shown in FIG. The results are shown in FIG. FIG. 4A shows the relationship between the rotational moment and the symbol of the swing weight by the 14-inch measuring device, and FIG. 4B shows the relationship between the rotational moment and the symbol of the swing weight by the 1-inch measuring device.

  Set A is a set having the same head and a different shaft length, and set B was measured so that the swing weight of each golf club of set A was measured by the swing weight measuring device 2 and adjusted so that each swing weight was the same. Is a set. The set C is a golf club set of the present embodiment, and is a set in which the swing weight of each golf club of the set A is measured by the swing weight measuring device 30 and adjusted so that the respective swing weights are the same.

  In this case, when the golfer performed a hit test on the golf club sets A, B, and C to evaluate the swing feeling, the golf club set C of the present embodiment obtained the highest evaluation of the sense of unity of the swing feeling. .

  In addition, this invention is not limited to embodiment mentioned above, For example, a wedge, a driver, etc. may be sufficient as a golf club set. It may also be a set of irons.
