い。[0004] Further, since the course itself is long distance and rugged, the amount of movement required for movement is large, and a two-seater or four-seater self-propelled cart must be used to reduce the amount of movement during movement. Also, when hitting a flying ball,
To hit a golf ball, which is a small-diameter hard ball, with the wood or iron club selected each time according to the flight distance, it is necessary to prepare a large number of wood clubs, iron clubs and putters, and it is expensive to prepare one set I have to be.

での負担も大きい。Further, since a golf ball hit with a wood or a long iron has a long flight distance, the hit golf ball tends to be lost if it is not properly inspected. The burden on the aspect is large.
【0006】以上挙げたような欠点は、特に子供、お年
寄り等がプレイをするのに大きな障害となり、ゴルフ人
口は子供、お年寄り等は少ないのが現状である。[0006] The above-mentioned drawbacks particularly hinder children and the elderly from playing, and the current golf population is small for children and the elderly.

用いて、当該パターゴルフコースを周りプレイするもの
である。[0007] In order to solve such a problem,
There is putter golf. The putter golf involves playing around the putter golf course using only golf balls and putters on an outdoor or indoor putter golf course, which is a green course mainly covered with artificial turf.

にまで広くプレイされている。[0008] The putter golf can be played outdoors and indoors, and since the putter golf course itself is small, the amount of movement during the movement is small, and all the golf balls are hit by rolling with the putter, so that the risk is low. The possibility of losing the golf ball is low. Therefore, it is widely played by children, the elderly and the like.
【0009】しかし、パターゴルフは、上述のように、
ゴルフ様の醍醐味に欠け、しかもゴルフボールを使用す
るため、人工芝等を敷き詰めた狭小のパターゴルフコー
ス上で行わないといけないという問題があった。However, putter golf, as described above,
There is a problem in that it lacks the real pleasure of golf, and must be performed on a narrow putter golf course covered with artificial turf and the like because a golf ball is used.
【0010】また、ゴルフボールの重量は、非常に軽い
ものであり、打撃の感触があまり無いものであった。他
にも、ゴルフボールは小径でかつ軽量なため、打球コン
トロールが難しく扱いにくいものであった。Further, the weight of the golf ball is very light, and the golf ball does not feel much hitting. In addition, since the golf ball has a small diameter and a light weight, it is difficult to control the hit ball and is difficult to handle.

よりも小規模なパークゴルフが開発された。パークゴル
フは、屋外において、主に芝生の敷き詰められた、地
面、丸太等を配置したパークゴルフコース上でプレイす
るスポーツである。As a sport that solves the drawbacks of putter golf balls, park golf smaller than golf has been developed. Park golf is a sport that is played outdoors on a park golf course on which the ground, logs and the like are mainly covered with grass.

スチック製の屋外パークゴルフ用ボールを打撃すること
により転がして、カップに屋外パークゴルフ用ボールを
少ない打数で入れることを競うものである。Basically, on a park golf course, a player hits a plastic park golf ball having a diameter of 6 [cm] using one park golf stick which is a club dedicated to park golf. Then, the player competes to put the ball for outdoor park golf into the cup with a small number of hits.
【0013】パークゴルフコースは、例えば、ゴルフの
ハーフコースと同様にして、全9コースで、規定打数が
3打のショートホールが2つ、規定打数が5打のロング

なるように配置される。The park golf course has, for example, a total of nine courses in the same manner as the golf half-course, with two short holes having a prescribed number of hits of two, two long holes having a prescribed number of strokes of two, and a prescribed number of hits. Are arranged so that there are five middle holes with four strokes.
【0014】しかし、パークゴルフをプレイするには、
当該パークゴルフコースは、前記のパターゴルフと同様
に屋外に造成されたパークゴルフコースまでわざわざ行
かなければならないという問題があった。However, to play park golf,
The park golf course has a problem that it is necessary to go to a park golf course created outdoors as in the case of the putter golf.
【0015】また、パークゴルフ用のボールは、屋外用
のものはあるが屋内用のものは無かった。There are park golf balls for outdoor use but not for indoor use.
【0016】もし、屋外パークゴルフ用ボールを用い
て、屋内の体育館等の木床等の平坦面上でプレイする場
合には、わざわざ人工芝等を敷き詰めなければならな
い。なぜならば、屋外パークゴルフ用ボールは当該木床
上では回転摩擦抵抗が小さく加速が付き過ぎてあまりに
も転がりすぎるために、あまり打撃加速を付けずに転が
らなくするように打撃をするには、屋外での打撃動作に
比べて腫れ物に触るような臆病な打撃動作をすることに
なり、良好な打撃感覚が得られなく、面白さに欠けるス
ポーツとなってしまうからである。When playing on a flat surface such as a wooden floor in an indoor gym or the like using an outdoor park golf ball, artificial turf or the like must be spread. The reason is that the ball for outdoor park golf has a low rotational friction resistance on the wooden floor and the roller is too accelerated, so that the ball is rolled too much. This is because a timid striking motion such as touching a swollen object is performed as compared with the striking motion, and a good striking sensation cannot be obtained and the sport lacks interest.
【0017】よって、木床等の平坦面上に人工芝等のマ
ット等を敷き詰めるには、時間、労力及び費用の面で負
担が大きく、やはり、屋外でプレイしなければならなか
った。Therefore, in order to spread a mat or the like such as artificial turf on a flat surface such as a wooden floor or the like, there is a large burden in terms of time, labor and cost, and it is necessary to play outdoors.
【0018】そのため、雨、雪、風、雷等の悪天候の場
合、冬等の寒い季節の場合、寒い地方の場合や、逆に、
直射日光が強い場合、夏等の暑い季節の場合、暑い地方
の場合においては、過酷なプレイとなるという問題があ
った。Therefore, in the case of bad weather such as rain, snow, wind, and lightning, in the case of a cold season such as winter, in the case of a cold region, or conversely,
When direct sunlight is strong, in a hot season such as summer, or in a hot region, there is a problem that severe play is caused.
【0019】また、屋外でプレイする場合でも、屋外に

等でプレイするには、やはり屋外パークゴルフ用ボール
はあまりにも転がりすぎるため、屋内の場合と同様に、
プレイを困難とした。In addition, even when playing outdoors, when playing on asphalt, tiles, or concrete flat surfaces outdoors, etc., the ball for outdoor park golf is still too rolled.
Made it difficult to play.
【0020】また、屋外パークゴルフ用ボールはゴルフ
ボールに比べて外径が大きいので、ゴルフボールに比べ
れば扱い易いが、屋外パークゴルフ用ボールはプラスチ
ック製であり、扱う手との間の摩擦が小さいという点で
重量が増した分滑り易く扱いにくいという問題があっ
た。Also, since the outside park golf ball has a larger outer diameter than the golf ball, it is easier to handle than the golf ball. However, the outdoor park golf ball is made of plastic, and the friction between the hand and the handling hand is reduced. There was a problem that it was slippery and difficult to handle because of its increased weight in that it was small.
【0021】また、ゲートボールについては既にゲート

内球は約7.5[cm]と外径が大きく比重が小さいの
で、そのまま外径の小さな平坦パークゴルフ用ボールに
同じ材料を適用すると、重量が小さくなり、同様に転が
り過ぎたり、打撃時に良好な打撃感が得られないという
問題があった。As for the gate ball, a gate ball indoor sphere has already been considered, and the gate ball indoor sphere has a large outer diameter of about 7.5 [cm] and a smaller specific gravity. When the same material is applied to the ball, the weight is reduced, and similarly, there is a problem that the ball rolls too much and a good hit feeling cannot be obtained when hitting.
