[Prior art]
Today, the distance of golf balls has increased dramatically due to improvements in golf balls. In particular, the dimples of the golf ball are indispensable for improving the aerodynamic characteristics at the time of flight of the golf ball and improving the flight distance. For this reason, many golf balls that define the shape of a dimple have been proposed.
[0003]
For example, Japanese Patent Laid-Open No. 11-57065 proposes a golf ball in which at least one dimple out of a plurality of types of dimples having a plurality of types of diameters is formed with at least two types of different cross-sectional shapes. ing.
According to this, it is said that aerodynamic characteristics can be improved and it has excellent flight performance.
Japanese Patent Application Laid-Open No. 2001-170212 includes a large number of three or more types of dimples having a circular planar shape and different circular diameters, and at least one type of cross-sectional shape of the dimple has another type of cross-section. A golf ball characterized by a different shape is proposed.
According to this, the dimples are optimized, the flight distance can be improved, and the aerodynamic characteristics can be improved.
[0004]
[Problems to be solved by the invention]
However, there are various types of swings performed when flying a golf ball. For example, a golf swing that causes a golf ball to fly with a low trajectory, a golf swing that causes a golf ball to fly with a high trajectory, and the like. There are various types, such as a golf swing located.
For such various types of golf swings, even if a golf ball having a uniform dimple cross-sectional shape and dimple arrangement is used, the flight distance of the golf ball may not be improved. The flight distance may be reduced.
For example, in the case of a golf swing of a type in which a golf ball is made to fly with a high trajectory, if a golf ball having a spin that greatly affects the behavior of the golf ball is used, the golf ball rises too high and the flight distance decreases. There's a problem.
[0005]
Therefore, in order to solve the above problem, the present invention provides a golf package for packing a golf ball belonging to a golf ball group capable of improving the flight distance corresponding to any golf swing when hitting the golf ball. The purpose is to provide.
[0006]

Furthermore, the present invention provides a golf ball belonging to the above golf ball group.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the golf package of the present invention will be described in detail based on a preferred embodiment shown in the accompanying drawings.
The golf ball group packed in the golf package of the present invention is a golf ball group in which golf balls are divided into a plurality of types, and the total volume of the recesses of the dimples arranged on the golf ball is large and small. It is characterized by a series of golf balls. Here, the series is a series of relationships in which golf balls are distinguished from each other such as types A, B and C or series I, II and III under a certain golf ball brand name, product name, etc. Say.
Here, the golf ball group may be divided into at least two types.
[0011]
FIG. 1A is a top view of a golf ball 1 as an example of a golf ball packed by the golf ball package of the present invention, and FIG. 1B is a front view.
The golf ball 1 has a plurality of two types of dimples α and β having different cross-sectional shapes, and is arranged at the apex and each side of the spherical regular pentagon 2.
A region R shown in FIG. 1B is a die connection region when the golf ball 1 is manufactured.
FIG. 2 shows the golf ball group 10 to which the golf ball 1 belongs, and FIGS. 3A and 3B show the cross-sectional shapes of the dimples α and β.
The golf ball group 10 shown in FIG. 2 is composed of golf balls of types A, B, and C divided into three types, and the golf balls of type A and type B have two types of dimples having different cross-sectional shapes. A type C golf ball having α and β in common is constituted by dimple β. The golf ball 1 shown in FIG. 1 corresponds to the type A in the golf ball group 10.
[0012]
The dimple α has a circular outer edge shape, and the cross-sectional shape of the dimple α when cut along a plane passing through the center position of the circle is a substantially trapezoidal shape. That is, the dimple α has a side surface portion that changes substantially linearly in the depth direction in the cross-sectional shape, and a bottom surface portion that is bent and connected to the side surface portion. Here, the bottom surface portion may be planar or spherical.
The outer edge shape of the dimple α is circular, but is not particularly limited in the present invention, and may be a polygonal shape such as a hexagonal shape.
On the other hand, the dimple β has a circular outer edge shape and a substantially arc shape with no cross section.
In the present invention, the outer edge shape of the dimple β is not particularly limited, and may be a polygonal shape such as a hexagonal shape.
Note that the volume of the concave portion of the dimple α is larger than the volume of the concave portion of the dimple β.
[0013]
Here, in the cross-sectional shape, the dimple α is bent at the connection position of the side surface portion and the bottom surface portion so that the side surface portion and the bottom surface portion can be clearly visually recognized. The tangent intersection angle θ (see FIG. 3A) is 90 to 120 degrees, preferably 95 to 115 degrees, and more preferably 100 to 110 degrees. By setting the inclination angle θ within this range, the dimple volume changes and the trajectory of the golf ball can be adjusted.
The crossing angle θ may be a golf ball design value in addition to the actual golf ball crossing angle, and the golf ball in the present invention may be a golf ball made of a mold designed with this design value, The manufactured golf ball may be polished or further coated after polishing. For example, a golf ball having a crossing angle θ set as a design value within the above range is manufactured, and even if the crossing angle θ deviates from the above range by polishing and coating the manufactured golf ball, the crossing angle θ Is treated as a golf ball substantially within the above range.
[0014]
On the other hand, in the types A and B, the dimples α are regularly arranged so as to be located at the apexes of the spherical regular pentagon 12 on the spherical surface of the golf ball. In each type of golf ball, the ratio of the number of dimples α to the total number of dimples is 31% for Type A, 15% for Type B, and 0% for Type C.
[0015]
In type A, ten dimples α are arranged along each side of the spherical regular pentagon 12 together with the apex of the spherical regular pentagon 12, and six dimples β are arranged in the inner region of the spherical regular pentagon. It becomes the composition. In other words, 10 dimples α and 6 dimples β are arranged on the side of the spherical regular pentagon 12 and in the region inside thereof.
On the other hand, in Type B, five dimples α are arranged at each vertex of the spherical regular pentagon 12, and eleven dimples β are arranged at sides other than the vertex of the spherical regular pentagon and the inner region.
In Type C, 11 dimples β are arranged in the side of the spherical regular pentagon 12 and the area inside the spherical regular pentagon 12.
In the regions other than the spherical regular pentagon 12, the dimples β are arranged in all of the types A, B, and C.
[0016]
Types A, B, and C all form a spherical regular pentagon 12 using dimple α or dimple β. Instead of spherical regular pentagon 12, for example, spherical regular triangle, spherical quadrangle, spherical regular A spherical regular polygon such as a hexagon may be formed.
[0017]
As described above, the number of the dimples α is increased in the order of type C, type B, and type A, and the total volume of the dimples recessed by the dimples α and β arranged on the golf ball is determined as type C and type. B is larger in the order of type A.
As the structure of the golf ball, a known structure such as a two-piece ball, a three-piece, or a wound ball can be used. This structure may be different for each type or the same structure.
[0018]
The above golf ball group is formed into a series using dimples α having a substantially trapezoidal cross section and dimples β having a circular cross section. Instead of the dimples α, as shown in FIG. The total volume of the recesses due to the dimples may be changed using a dimple γ having a triangular cross-section and a smaller volume than the dimple β.
Each of the types A, B, and C of the golf ball group has the same arrangement method in which at least one of the dimples α and β is arranged at each vertex and each side of the spherical regular pentagon 12 and the center position of the spherical regular pentagon 12. However, in the present invention, the method is not limited to changing the total volume of the recesses by the dimples by this method.
[0019]
Each type of golf ball group includes a first dimple group in which the cross-sectional shape of the dimple concave portion is the same between the types, and a second dimple in which the cross-sectional shape of the concave portion is different and the volume of the dimple concave portion is different between the types. The dimple group has a dimple group, and the first dimple group and the second dimple group of the plurality of types of golf balls are provided in the same arrangement pattern between the types, thereby changing the total volume of the recesses by the dimples. Also good.
For example, as shown in FIG. 5, a group of dimples arranged on the side of the spherical regular pentagon 14 and at the center position of the spherical regular pentagon 14 is a first regular dimple group, a spherical regular pentagon adjacent to the inside of the spherical regular pentagon 14. A group of dimples arranged on the side of 14 ′ is defined as a second dimple group. The dimple α is located on the side of the spherical regular pentagon 14 of the first dimple group, and the central position of the spherical regular pentagon 14 of the first dimple group is set. Assign dimple β.
In type I, dimple α is assigned to the second dimple group, in type II, dimple β is assigned to the second dimple group, and in type III, dimple γ is assigned to the second dimple group.
There are two types of dimples in each type of golf ball, such as type I, type II, dimples α and β, and type III, dimples α and γ, but the present invention is not limited to two types. One type or three or more types may be used.
In FIG. 5, dimples in the outer region of the spherical regular pentagon 14 are omitted.
In this way, the total volume of the recesses by dimples may be changed.
[0020]
【Example】
Hereinafter, although an example explains the effect of a golf ball group about a golf ball which a golf package of the present invention packs , the present invention is not limited to the following example.
As the golf ball group, three types (types A, B and C) of golf balls shown in FIG. 2 were produced.
All the golf balls have a three-piece structure.
[0021]
The crossing angle θ in the dimple α in types A and B was designed to be 105 degrees (see FIG. 3A).
In each type of golf ball, the ratio of the number of dimples α to the total number of dimples is 31% for Type A, 15% for Type B, and 0% for Type C. Therefore, the total volume of the recesses due to the dimples increases in the order of type C, type B, and type A.
The golf ball was subjected to a coating treatment by polishing the surface of the golf ball. Accordingly, the total volume of the concave portions due to the dimples is reduced, but the relative order of the total volumes of the types A, B and C after painting is not changed.
[0022]
The produced golf balls of types A, B and C were trial hit using a driver with a swing robot manufactured by Miyamae Co., Ltd. so that the initial speed was 60 (m / sec).
At the time of trial hit, trial hits were made under different conditions 1 and 2 with different backspin amounts, the golf ball carry distance (distance from the golf ball hitting point to the first landing point), and total flight distance ( The distance from the golf ball hitting point to the stop was measured.
Condition 1 is a test hit condition in which a golf ball flies on a low trajectory with a launch angle of 13 degrees, a back spin as small as 1500 rpm. Condition 2 is a test hit condition in which a golf ball flies along a high trajectory with a launch angle of 13 degrees, a back spin as large as 3000 rpm. The measurement results are shown in Table 1 below.
[0023]
[Table 1]

[0024]
According to Table 1, it can be seen that the flying distance of Condition 1 where the backspin of the golf ball is small is shorter for the golf ball of Type A than the flying distance of Condition 2 where the backspin is large, but is extended in Type C.
For example, in Type A, the total flight distance is shorter by about 2 m in Condition 1 than in Condition 2, whereas in Type C, the total flight distance is extended by about 10 m in Condition 1 compared to Condition 2. In condition 1, the total flight distance of type C is longer than that of type A, and in condition 2, the total flight distance of type A is longer than that of type C.
[0025]
As a result, the golf ball hit with less golf ball has less backspin and the golf ball flies with a low trajectory. Type C golf ball has a higher backspin and has a higher trajectory. By providing a golf ball of type A for the golf swing of the type that causes the ball to fly, and a golf ball of type B for the intermediate type of golf swing, it is possible to improve the flight distance.
In addition, by using a desired type of golf ball, it is possible to realize a golf play strategy intended to fly a golf ball far away with a low trajectory.
[0026]
Such a group of golf balls may be provided to the golfer as a set of three types, or each golf ball may be classified by type and provided to the golfer.
The present invention includes golf balls of the type belonging to such a golf ball group.
When a golf ball is provided that is classified by type, as described above, one type of golf ball in the group of golf balls in which the golf ball is classified by type because the total volume of the dimple recesses is different. Is displayed, and the purchaser can purchase a golf ball based on this information.
The information is preferably displayed on a golf ball package, a golf ball sales promotion brochure, or an advertisement.
