Description

  The present invention relates to a golf club and a golf club set.

  A golf club set composed of a plurality of counts is generally designed such that the higher the club with the larger loft angle, the greater the face progression. However, when face progression increases, there is a problem that the leading edge protrudes forward at the time of addressing, which makes it difficult to hold.

  In view of this, the golf club set according to Patent Document 1 has a constant face progression with a plurality of counts. If the face progression is constant, there is an advantage that it becomes easier to hold a club with a higher count at the time of addressing.

JP 2012-6135 A

  However, when the face progression is constant, the position of the hosel part in the face-back direction with respect to the face part greatly varies between counts. Therefore, when hitting with different counts, for example, after hitting with a lower count club, when hitting with a higher count club, there is a sense of incongruity and the timing of impact at the time of hitting shifts Can occur. The present invention has been made to solve the above-described problems, and it is an object of the present invention to provide a golf club and a golf club set that are easy to set up even with a high-numbered club and that do not easily shift the impact timing even when the number is changed. And

  The golf club according to the present invention is a golf club included in a golf club set having a golf club composed of a plurality of counts having different loft angles, and includes a shaft and a golf club head, and the golf club The head includes a crown portion, a face portion, a sole portion, and a hosel portion to which the shaft is attached, and at least one set of adjacent golf balls of a plurality of golf clubs included in the golf club set In the club, the length in the face-back direction of the face portion in a plan view of the golf club with a large count is larger than the length in the face-back direction of the face portion in a plan view of the golf club with a small count, The difference in length is ΔAmm, and in the plurality of golf clubs, the count is When the face progression of a golf club is larger than the face progression of a golf club with a small number and the difference in face progression is ΔBmm, (1/3) × ΔA ≦ ΔB ≦ (2/3) × ΔA, Is satisfied.

  Note that the “golf club set” defined in the present invention does not necessarily mean that a plurality of golf clubs are necessarily sold at the same time, and may be sold individually. That is, it is sufficient that it is recognized as a combination of golf clubs having different loft angles in at least the same series, and the golf club according to the present invention may be one of them.

  In the golf club, it is preferable that ΔA and ΔB satisfy (5/12) × ΔA ≦ ΔB ≦ (7/12) × ΔA.

  In each of the golf clubs, a loft angle of the golf club included in the golf club set may be 15 to 30 degrees.

  The golf club set according to the present invention is a golf club set having a golf club composed of a plurality of counts having different loft angles, and each of the golf clubs includes a shaft and a golf club head, Each golf club head includes a crown portion, a face portion, a sole portion, and a hosel portion to which the shaft is attached. Among the plurality of golf clubs, at least one set of adjacent count golf clubs, The length in the face-back direction of the face portion in a plan view of a golf club with a large count is larger than the length in the face-back direction of the face portion in a plan view of a golf club with a small count. Is a difference of ΔAmm, and in the plurality of golf clubs, E over scan progression is greater than face progression of a golf club wherein the count is small, the difference between the face progression is when a DerutaBmm, satisfies, (1/3) × ΔA ≦ ΔB ≦ (2/3) × ΔA.

  According to the present invention, it is easy to hold a club with a high count, and even if the count is changed, the timing of impact can be made difficult to shift.

It is a perspective view of the standard state of one golf club head of the golf club set concerning one embodiment of the present invention. It is a top view of FIG. It is an example of the golf club set concerning this embodiment, and is a top view (a) of a golf club head in a standard state, and a side view (b). It is the top view which contrasted the golf club set which concerns on this embodiment, and the conventional golf club set. It is a top view of the golf club set concerning this embodiment.

  Hereinafter, one embodiment of a golf club set according to the present invention will be described with reference to the drawings. The golf club constituting the golf club set according to the present embodiment is a utility type golf club), for example, a 2-6 utility. As will be described later, the clubs are mainly different in the loft angle, the position of the hosel part, and the like. In the following, first, one golf club is taken as an example, a common structure is outlined, and differences in each golf club number in the golf club set are described in detail.

<1. Overview of golf club head>
First, taking one golf club (No. 3 utility) in the golf club set according to the present embodiment as an example, the golf club head will be described. FIG. 1 is a perspective view of a reference state of one golf club head in a golf club set according to the present embodiment, and FIG. 2 is a plan view of FIG. The reference state of the golf club head will be described later.

  As shown in FIG. 1, this golf club head (hereinafter sometimes simply referred to as “head”) has a hollow structure, and includes a face portion 1, a crown portion 2, a sole portion 3, a side portion 4, and a hosel portion 5. The wall surface is formed by.

  The face portion 1 has a face surface that is a surface for hitting a ball, and the crown portion 2 is adjacent to the face portion 1 and constitutes the upper surface of the head. The sole portion 3 constitutes the bottom surface of the head and is adjacent to the face portion 1 and the side portion 4. Further, the side part 4 is a part between the crown part 2 and the sole part 3 and extends from the toe side of the face part 1 to the heel side of the face part 1 through the back side of the head. Further, the hosel portion 5 is a portion provided adjacent to the heel side of the crown portion 2 and has an insertion hole 51 into which a golf club shaft (not shown) is inserted. The central axis Z of the insertion hole 51 coincides with the axis of the shaft.

  Here, the reference state described above will be described. First, as shown in FIGS. 1 and 2, the central axis Z is included in a plane P1 perpendicular to the ground (horizontal plane), and the head is placed on the ground at a predetermined lie angle and real loft angle. Is defined as the reference state. The plane P1 is referred to as a reference vertical plane. In addition, as shown in FIG. 2, the direction of intersection between the reference vertical plane P1 and the ground is referred to as a toe-heel direction, and a direction perpendicular to the toe-heel direction and parallel to the ground is defined as a toe-heel direction. The face-back direction will be referred to. In the golf club set according to the present embodiment, the loft angle increases as the club number increases, as in a general golf club set.

  In the present embodiment, the boundary between the sole part 3 and the face part 1 and between the sole part 3 and the side part 4 can be defined as follows. That is, when a ridge line is formed between the sole part 3 and the face part 1 and between the sole part 3 and the side part 4, this becomes a boundary. In addition, the golf club head according to the present embodiment has the side portion 4. However, for example, when the sole portion 3 is not directly connected to the crown portion 2 without the side portion 4, A ridge line between the portion 3 and the crown portion 2 serves as a boundary between them. In addition, when a clear ridge line is not formed, the head is set in a reference state, and the outline when viewed from directly above the center of gravity of the head is a boundary.

The upper limit of the head volume is not particularly defined, but practically, for example, 500 cm 3 or less is desirable, and 470 cm 3 or less is desirable when complying with R & A and USGA rules.

  The head can be formed of, for example, a titanium alloy (Ti-6Al-4V) having a specific gravity of about 4.4 to 4.5. Further, in addition to the titanium alloy, it can be formed by using one or more of stainless steel, maraging steel, aluminum alloy, magnesium alloy, amorphous alloy, and the like.

  Note that the head according to the present embodiment is configured by combining at least the head main body having the sole portion 3 and other portions. For example, only the face portion 1 is formed of a separate member and attached to the head body to form a head, or a head body having openings in the crown portion 2 and the side portion 4 is formed, and the opening is formed of a separate member. The head can also be configured by closing.

<2. Differences between counts in golf club sets>
Next, the difference between the counts in the golf club set will be described with reference to FIG. FIG. 3 is a plan view (a) and a side view (b) of a plurality of golf club heads in a reference state. In FIG. 3, as an example, the heads of three golf clubs adjacent to each other in the golf club set according to the present embodiment are shown. The third utility (U # 3) and the fourth utility (U #) 4) and No. 5 utilities (U # 5) are arranged in this order from top to bottom. 4 and 5 to be described later, including FIG. 3, for explaining the difference between the counts, each head is slightly exaggerated to clarify the features of the invention. Therefore, although it differs from the actual angle and shape shown in Table 1 etc., this does not change the essence of the invention.

  In FIG. 3, the position of the leading edge E of the face portion 1 of each golf club head is aligned. That is, the leading edge E of the face portion 1 of each golf club head is in contact with the line X. All the golf club heads are formed so as to have substantially the same length L in the face-back direction (hereinafter referred to as “head width”) in plan view. However, the head width L does not need to be completely the same for each club of each count, and for example, the head width L can be reduced as the count increases. At this time, in order to make the head width L the same as much as possible, for example, it is preferable that the head width L of a club with a large count is 80 to 100% of the head width L of a club with a small count between adjacent counts, More preferably, it is 90 to 100%, and particularly preferably 95 to 100%. The head width is the maximum width in the face-back direction in plan view. Further, a symbol L in FIG. 3 indicates the head width of the third utility.

  Further, the length A (hereinafter referred to as “face width”) in the face-back direction in the face portion 1 of each head in a plan view becomes longer as the club number increases. The face width A is the maximum width in the face-back direction in plan view. As described above, in the golf club according to the present embodiment, although the head width L of each head is substantially the same, the face width A is longer as the club having a larger count, so the volume of each head is The club with the higher count is smaller.

  Furthermore, in the present embodiment, the distance B in the face-back direction in plan view between the leading edge E of the face portion 1 of each head and the hosel portion 5, that is, the so-called face progression becomes longer as the club number increases. ing.

In the golf club set according to the present embodiment, the following relationship is satisfied between the counts for the face width A and the face progression B described above. That is, the heads are designed so that the difference ΔA in the face width A and the difference ΔB in the face progression B satisfy the following expression (1) in the adjacent count heads. ) Is preferably satisfied.
(1/3) × ΔA ≦ ΔB ≦ (2/3) × ΔA (1)
(5/12) × ΔA ≦ ΔB ≦ (7/12) × ΔA (2)

As an example, the head width, loft angle, head volume, face width, and face progression of the third utility, the fourth utility, and the fifth utility according to the present embodiment are shown below.

  According to Table 1, ΔA and ΔB between the counts satisfy the above formula (1).

<3. Features>
Hereinafter, the effect obtained by the golf club according to the present embodiment will be described with reference to FIG. First, the design of a conventional golf club will be described. The conventional golf club set described here includes utility type golf clubs as in the above embodiment, and third wood, fourth wood, and fifth wood are given as examples.

(Conventional example 1)
In the golf club set design in this example, as shown in FIG. 4 (a), the lengths of the crown portions 2 in the face-back direction are the same in the clubs of all the counts in the face-back direction. As the loft angle increases, the above-described head width L increases. That is, the upper end position of the face portion 1 is the same for all the iron numbers, but the lower end position (leading edge position) of the face portion 1 is changed. Further, the hosel portion 5 is disposed at the face side end of the crown portion 2 in the face-back direction at all counts. That is, the face progression B is larger as the club is larger.

(Conventional example 2)
As shown in FIG. 4B, the golf club set design in this example has substantially the same head width L for all the counts. The face width A described above becomes longer as the loft angle becomes larger. That is, the upper end position of the face portion 1 varies between counts, but the lower end position of the face portion 1 is the same. Further, the face progression is the same in all the counts.

(Differences between the golf club set according to the present embodiment and the conventional examples 1 and 2)
First, Conventional Examples 1 and 2 have the following problems. First, in Conventional Example 1, the club with the larger count has a larger face progression B and a larger head width L. For this reason, in particular, a club with a high count has a problem that it is difficult to hold because the leading edge protrudes forward greatly at the time of addressing. In addition, there is a problem that the timing of impact at the time of hitting is shifted between counts.

  In Conventional Example 2, although the face progression B does not change, the position of the hosel part 5 with respect to the face part 1 changes greatly, so that a sense of incongruity when striking with a different count is increased. Further, for example, after hitting with a low-numbered club, after hitting with a high-numbered club, the face of the higher-numbered club is sleeping, so the timing of impact may be shifted.

  On the other hand, in the golf club set according to the present embodiment, as shown in FIG. 4C, the relationship between the difference ΔA in the face length A and the difference ΔB in the face progression B is expressed by the above equation (1). Like that. Therefore, the difference in face progression B between the counts is small, and the change in the position of the hosel part 5 relative to the face part 1 is also small. Therefore, even a high-numbered club can be easily set at the time of addressing, and even if it is hit by changing the number, it can reduce the uncomfortable feeling. As a result, the impact timing at the time of hitting can be reduced from being shifted between counts. Further, by making the head width L substantially the same between the counts, it is possible to reduce the uncomfortable feeling.

  When the relationship between ΔA and ΔB satisfies the above equation (2), particularly when ΔB is in the vicinity of ½ × ΔA, as shown in FIG. Since the distance Lh between the imaginary straight line Y passing through the center of the direction and parallel to the toe-heel direction and the hosel portion 5 is almost the same, it is possible to further reduce the deviation of the impact timing at the time of hitting.

<5. Modification>
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible unless it deviates from the meaning. For example, the following changes can be made.

<4.1>
In the above embodiment, the relationship of the above formula (1) is particularly satisfied between the counts. However, in the golf club set, the golf club set does not necessarily include the formula (1) in all adjacent count golf clubs. It does not have to be satisfied. That is, it is sufficient that the expression (1) is satisfied between at least one pair of adjacent counts in the golf club set. Further, when the head width is changed between counts, it is sufficient that the head width is changed between at least one adjacent count.

<4.2>
Although the utility type golf club and the golf club set including these have been described in the above embodiment, the golf club and the golf club set according to the present invention are not limited to this. For example, a golf club set including a wood-type golf club (for example, 1-9 wood) may be used. Even in such a golf club set, the above-described relationship of ΔA and ΔB can be applied. In the case of a wood-type golf club, the head width L may not be the same. For example, the head width can be reduced as the count increases (for example, 1 to 30% of the head). Width can be reduced).

  Further, the golf club set according to the present invention means a golf club set including the same kind of golf clubs. For example, only one utility type golf club or only a wood type golf club is included in one golf club set. included.
