Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates generally to a floating golf ball and water golf-practicing system that are designed to allow the golfers to play golf on the water such as river, lake or sea.

2. Description of the Prior Art

Modern golf balls, with their diameters of 42.67 mm and weights of 45.939 or below, available on the market are typically made to be used only on the ground. Golf ball manufacturers have been developing new golf balls to improve the quality and performance of their golf balls, by changing their construction and materials.

However, most of golf balls sold on the market are manufactured to be used only on the land so that no consideration is given to the possibility of their floating on water. The primary reason most of golf ball manufacturers do not consider about the floating function of the golf balls on the water is because the performance of their golf balls may not be maximized if such consideration is given.

The present invention enables the golf players to play golf on the river, lake or sea by installing the golf-practicing system designed according to the present invention. In order to achieve aforementioned objectives, a golf ball according to the present invention has lower specific gravity and higher buoyancy than other golf balls available on the market. Furthermore, the core of the golf ball according to the present invention is made of highly-repulsive materials.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a floating golf-ball designed to be used on the water. Another purpose of the present invention is to provide a floating golf ball that enables the golf players to collect the golf balls floating on the water during and after playing of the golf. A further purpose of the present invention is to provide a floating golf ball so that the golf players can practice golf on the river, lake or sea, driving the golf ball above the water and enjoying swimming or water sports at the same time.

Other advantages and objectives of the invention will be in part obvious and in part pointed out more in detail hereinafter. First, many people can practice golf in a limited space with this floating golf ball and water golf-practicing system according to the present invention since the golf balls according to the present invention fly above and falls on the water. No field is necessary as in typical driving ranges except for the portion of the driving box which shall be placed on the land or on the deck of a boat, from where the golfers drive the floating golf balls toward the water. Also, the floating golf balls are collected after or during practice without missing balls since they float on the water.

Secondly, the present invention contributes to the cost-saving of the golf industry since no land or expensive system is necessary for practicing golf when the golf industry uses the present invention.

Finally, the present invention also contributes to the promotion of golf since the initial investment in the golf-practicing facility according to the present invention is considerably lower than the conventional driving ranges, so that many people can practice golf at an expensive price.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The present invention will be described in detail by way of a preferred embodiment with reference to accompanying drawings, in which like reference numerals are used to identify the same or similar parts. [0017]
The functions and structure of the present invention as depicted on the drawings are as follows: [0018]
As seen in FIG. 1 which shows the cross-section of the floating golf ball according to the present invention, the floating golf ball according to the present invention comprises: a [0019] core 1 made of cork, Styrofoam® or synthetic resin whose diameter is ±5 mm and weight is 1.5 g; a synthetic rubber inner cover layer 2 whose weight is 27 g, disposed about the core; and a dimple-type hardened outer cover layer 3 whose thickness is 2+0.5 mm and weight is 11.5 g, disposed on the synthetic rubber inner cover layer 2.
The diameter and weight of the floating golf ball according to the present invention are 43 mm and 40 g respectively for example, and the specific gravity of the floating golf ball according to the present invention is less than that of other golf balls available on the market. [0020]
The core objective of the present invention is to provide a floating golf ball that has the same or better performance compared to other conventional golf balls available on the market. Accordingly, the floating golf ball according to the present invention is not significantly lighter in weight or bigger in size than the conventional golf balls available on the market so that it may have the same or better performance compared to them, in addition to an advantage as a floating golf ball. [0021]
Referring now to FIG. 2, there is shown the water golf-practicing system according to the present invention installed on a river. The water golf-practicing system comprises a driving box[0022] 2-a where people drive the floating golf ball according to the present invention toward the river 2-b.
