Description

Description: FIELD OF THE INVENTION The present invention relates to golf club sets.

2. Description of the Related Art A golf club set includes a plurality of wood clubs, a plurality of iron clubs, and a putter. The wood clubs and the iron clubs each have a small count long-distance club to a count. It is configured by selecting an appropriate number from a series of large short distance clubs. The loft angle of each club in this series is gradually increased as the count increases, and the difference in the loft angle between the counts is usually constant: 3 degrees for wood clubs and 4 degrees for iron clubs. There is. The loft angle is an extremely important factor for determining the flight distance, and by setting the loft angle in this way, the flight distance can be determined by reducing the flight distance to substantially equal intervals by increasing the count.

In recent years, flight distance has generally increased due to improvements in golf clubs, golf balls, and physical strength of golfers. For this reason, in the series of clubs set as described above, the difference in flight distance between the counts becomes large, and inconvenience occurs especially in short-distance clubs in which an accurate flight distance is desired. Incidentally, clubs for shorter distances such as sand wedges and dual wedges have been added to cope with the increase in the flight distance, but this is not a countermeasure against the above-mentioned decrease in the accuracy of the flight distance.

Therefore, the present invention has been devised for the purpose of improving the above-mentioned inconvenience and reducing the carry distance difference between counts in a short distance.

Means for Solving the Problems The present invention is directed to a series of clubs ranging from a club with a small count to a long distance club to a club with a large count to a short distance. Is a golf club set formed by selecting an appropriate number of clubs from this series.

Action In the series of clubs formed in this way, the loft angle difference becomes smaller and the flight distance difference becomes smaller as the count becomes larger, that is, the one for a shorter distance.

EXAMPLES Hereinafter, the present invention will be specifically described with reference to Examples.

The series of wood clubs used in the present invention have the loft angles shown in Table 1. The flight distances shown in this table are standard values when the head speed is 40 m / s.

As a comparative example, Table 2 below shows a series of conventional wood clubs together with the flight distance.

The iron club series used in the present invention have loft angles and flight distances shown in Table 3. PW, DW, and SW represent a pitching wedge, a dual wedge, and a sand wedge, respectively.

Table 4 below shows a series of conventional iron clubs as a comparative example.

The loft angles and flight distances described above are shown in the graph of FIG.
It looks like Figure 4. That is, FIG. 1 is a loft angle of a wood club, FIG. 2 is a flight distance of a wood club, FIG. 3 is a loft angle of an iron club, and FIG. 4 is a flight distance of an iron club. The vertical axis represents the distance. In these figures, the series of the present invention is shown by black dots, the clubs are connected by solid lines, and the series of the comparative example is ×.
It is shown by a mark, and the broken lines connect the clubs.

The series of the present invention is a graph of loft angle (Figs. 1 and 3).
In the above, the line connecting the clubs has a curved shape that is convex upward, and in the flight distance graphs (FIGS. 2 and 4), the line is a curved shape that is convex downward. In the comparative example (conventional example), the same line is linear in any of the graphs.

The golf club set of the present invention is configured by selecting an appropriate number of clubs from the above series. For example, from the series of the wood clubs, the first, third, and fourth are selected, and the series of the iron clubs is selected. From No. 3, 4, ..., No. 11 and Pitching wedging, and putter is added.

Effects of the Invention In the golf club set of the present invention, as described above, the degree of loft angle increase decreases as the count increases,
Because the difference in flight distance between counts is getting smaller,
A more appropriate club can be used when used at a short distance where an accurate flight distance is required.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a graph showing the relationship between the count and loft angle of the wood club series used in the present invention and the series of comparative examples, and FIG. 2 shows the relationship between the count of the same series and the flight distance. It is a graph. FIG. 3 is a graph showing the relationship between the iron number and the loft angle of the iron club series used in the present invention and the comparative example series, and FIG. 4 is a graph showing the relationship between the number of the same series and the flight distance.
