It is a chart which shows an example of the relationship between a count and a frequency. FIG. 3 is a reference diagram illustrating an iron as an example of the golf club set of the embodiment for convenience of explanation.

As a result of diligent research, the present invention is a shaft set for golf clubs and a shaft set for golf clubs, which allows golfers to swing at a stable rhythm and timing, not only improving the score but also enjoying comfortable play. The golf club set using the above is embodied by paying attention to the shaft for a golf club and the frequency of the golf club.

1 and 2 show, as an example of a golf club, soft (the shaft of the golf club is a soft type and a general notation R shaft), and normal (the shaft of a golf club is a normal type and a general notation S). It is a figure which shows the relationship between the count and the frequency of the golf club set which has three kinds of characteristics of (shaft) and hard (the shaft of a golf club is a hard type and is a general notation X shaft). The golf clubs shown in these figures are DR # 1 (driver), FW # 3 (3rd wood), FW # 5 (5th wood), UT # 3 (3rd utility), and UT # 4. (No. 4 Utility), IR # 5 (No. 5 Golf Club), IR # 6 (No. 6 Golf Club), IR # 7 (No. 7 Golf Club), IR # 8 (No. 8 Golf Club), IR # 9 (No. 4 Golf Club) 9th golf club), IR # 10 (10th golf club), IR # AW (approach wedge), IR # SW (sand wedge). The above combination is selected for convenience of explanation and is not limited to this. An optimum combination may be appropriately selected and used as a shaft set for a golf club and a golf club set, or as an iron club set. good.

Hereinafter, it will be described with reference to FIGS. 1 and 2. FIG. 2A shows the distribution of the frequency of each count of a soft (general notation is R), normal (general notation is S), and hard (general notation is X) golf club set. 2 (b) is a chart showing the numerical values that are the basis for showing the distribution of FIG. 2 (a). As can be seen from this distribution, for example, in a soft golf club set, the frequency of DR # 1 is 210 CPM, and the frequency increases as the count increases, and the frequency of IR # SW. Is 296 CPM.

As described above, in a general golf club set, the frequency increases as the count increases. The unit CPM of the above frequency is "Cycles Per Minute", and is a numerical value measured how many times the shaft sways in one minute. Further, the frequency is, for example, a value obtained by measuring a shaft or a golf club using a frequency measuring device and quantifying the measured frequency at a minute speed.

The present invention focuses on the fact that in the above-mentioned general golf club set, it is difficult to swing at a constant rhythm and timing due to the difference in the frequency of each club.

That is, in the golf club shaft set and the golf club set of the present invention, each of the plurality of golf club shafts formed so as to be sequentially shortened as the count increases has the same frequency. Each of the plurality of golf clubs using these is formed so as to have the same frequency as shown in FIGS. 1 (a) and 1 (b). The same frequency mentioned above has a predetermined allowable range, and in this example, the predetermined allowable range is within plus or minus 2.5% centering on the reference frequency. However, the present invention is not limited to this, and the shaft set for golf clubs and the golf club set of the present invention may be designed by appropriately setting an optimum allowable range. Further, in this example, the same frequency described below is also as described above.

FIG. 1A shows, as an example of the present invention, vibration of each count of a soft (generally R notation), normal (generally S notation), and hard (generally X notation) golf club set. The distribution of numbers is shown, and FIG. 1 (b) is a chart showing the numerical values that are the basis for showing the distribution of FIG. 1 (a).

As can be seen from this distribution, in a soft (generally R notation) golf club set, the frequency of DR # 1 is 210 CPM, and the frequency is constant as the count increases. The frequency of IR # SW is also 210 CPM. In a normal (generally S notation) golf club set, the frequency of DR # 1 is 240 CPM, and the frequency is constant as the count increases, and the frequency of IR # SW is also the same. It is 240 CPM. Further, in a hard (generally X notation) golf club set, the frequency of DR # 1 is 270 CPM, and the frequency is constant as the count increases, and the frequency of IR # SW is high. Is also 270 CPM.

As mentioned above, the club sets so far have been made so that the frequency gradually increases from the driver to the sand wedge even if the shaft has the same notation. However, regardless of past conventions, when shafts with the same notation are set, for example, by manufacturing the shaft so that the frequency is constant from the driver to the sand wedge, the conventional problem can be solved. become.
