Abstract
The combination of (a) a multi-hole short golf course, playable with conventional golf clubs, with the length of the holes from tee to green varying from about 60 yards to about 195 yards and with a cup on each green having a diameter of about 8 to 10 inches; and (b) an oversize hollow inflated golf ball with which the short golf course is played. The golf ball comprises: a durable spherical plastic ball having an inflated diameter of 3.0 to 4.0 inches, a wall thickness of 0.170 to 0.220 inch, a weight of 90 to 100 grams, and an air pressurization of 8 to 10 pounds per square inch. The ball has 8 to 10 dimples per square inch in its exterior surface, each of the dimples having a depth of 0.018 to 0.022 inch and a diameter of 0.250 to 0.310 inch. The ball wall is constructed of vinyl polymer, or vinyl copolymer, containing a plasticizer. The ball wall has a hardness of about Shore A 70 Durometer. The ball has an aperture for receiving air under pressure. The aperture is sealed by a resilient plug inserted therein, whereby the air pressurization is maintained within the inflated ball.
