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.

Claims

1. The combination of:

(a) a golf course, and

(b) an oversize hollow inflated golf ball with which said golf course is played comprising;

(1) 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;

(2) said ball having 8 to 10 dimples per square inch in its exterior surface, each of said dimples having a depth of 0.018 to 0.022 inch and a diameter of 0.250 to 0.310 inch;

(3) said ball wall being constructed of plasticized vinyl polymer or vinyl copolymer, said ball wall having a hardness of about Shore A 70 Durometer; and

(4) said ball wall having an aperture for receiving air under pressure, said aperture being closed by a resilient plug inserted therein, whereby said air pressurization is maintained within said inflated ball.

2. The combination of claim 1 in combination with selected conventional regulation golf clubs with which, together with the oversize hollow inflated golf ball of claim 1, the course is played.

3. The combination of claim 1 wherein the holes of said course range from about 60 to about 195 yards in length.

4. An oversize hollow inflated golf ball for use in a game of golf, said golf ball comprising:

(a) 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;

(b) said ball having 8 to 10 dimples per square inch in its exterior surface, each of said dimples having a depth of 0.018 to 0.022 inch and a diameter of 0.250 to 0.310 inch;

(c) said ball wall being constructed of plasticized vinyl polymer or vinyl copolymer, said ball wall having a hardness of about Shore A 70 Durometer; and

(d) said ball wall having an aperture for receiving air under pressure, said aperture being closed by a resilient plug inserted therein, whereby said air pressurization is maintained within said inflated ball.

5. An oversize hollow inflated golf ball for use in a game of golf, said golf ball comprising:

(a) a durable spherical plastic ball having an inflated diameter of 3.25 inches, a wall thickness of 0.2 inch, a weight of 95 grams, and an air pressurization of 9 pounds per square inch;

(b) said ball having 9 dimples per square inch in its exterior surface, each of said dimples having a depth of 0.020 inch and a diameter of 0.280 inch;

(c) said ball wall being constructed of a vinyl polymer containing a plasticizer, and having a hardness of about Shore A 70 Durometer; and

(d) said ball wall having an aperture for receiving air under pressure, said aperture being closed by a resilient plug inserted therein, whereby said air pressurization is maintained within said ball.
