Definitions

  • the present invention relates to miniature golf links, mores specifically to miniature golf links used for enjoying playing golf in an area smaller than formal golf links.
  • golf links that is, a poor profitability. This has caused the necessity of a 18-hole course for a 18-hole game, requiring a large tract of land of about 594,000 m2 and a large amount of expense for constructing formal golf links. This is the reason for the deficiency of golf links, exceedingly high charge for a game, and a long queue of players, etc., and has long prevented a nice sport golf from being popular among public people.
  • some golf links have recently caused the problem of water pollution by applying harmful agricultural chemicals on the large area of their grass links, developing a severe social problem of polluting adjacent river and underground water as well as the links themselves. They used agricultural chemicals to protect their large grass links against diseases and bad insects with no alternative means.
  • the principal object of the present invention is to provide a golf ball for miniature golf links for enjoy playing golf in links smaller than formal golf links.
  • Another object is to provide miniature golf links for playing a pseudo-formal-golf game with a golf ball of smaller flight distance in an area smaller than formal golf links.

  • Figures 45 through 49 show a golf ball of half flight distance (about 100 m) of a formal golf ball by a full swing with an ordinary golf club such as a driver, etc.
  • the ball is made in equal diameter and weight to a formal golf ball, divided into 3 layers and made gradually softer to an inner layer. The approaching and putting steps can be performed similarly to the formal golf ball.
  • a golf ball 70 shown in Figure 46 is designed in the ordinary range of 41.15 - 41.67 mm in diameter, and the weight 44.50 - 45.92 also in the ordinary range. It is divided into three parts: a surface part 70a, intermediate part 70b, and core 70c.
  • the surface part 70a is made of the same material as a formal golf ball including rubber and filler
  • the intermediate part 70b is made of a material of larger gravity and softer property
  • the core is formed hollow.
  • the weight of the surface part 70a must be the total weight of the intermediate part 70b and the core 70c. Therefore, the gravity of the composite of the intermediate part 70b must be much larger than the surface part 70b because the core is hollow and zero in gravity.
  • the golf ball 70 is set in the range of the diameter and weight of a formal golf ball, and made hollow at the core 70c, the whole weight is concentrated to the surface part 70a and the intermediate part 70b. Therefore, the weight is the same as a formal golf ball, but the moment of inertia is larger.
  • a golf ball 70 has a tee hole 70d in the surface part 70a and the intermediate part 70b in the diameter direction. As shown in Figure 49, the ball is placed on a tee 72 set up on the grass 71 with the top tip of the tee set into the tee hole 70d.
  • the desirable tee hole 70d is 4 - 8 mm in depth and 3 - 5 mm in diameter.
  • the configuration of the tee hole 70d and the top tip 72a can be applied to the golf ball of normal flight distance.
  • the surface part 70a of the above mentioned golf ball is made of the same composite as a formal solid golf ball comprising rubber and filler, and the intermediate part 70b of softer and larger gravity composite than the surface part composite. Therefore, the ball is gradually softer from the surface part 70a through the intermediate part 70b to the core 70c. With this property, the ball 73 cannot absorb the impact only in the surface part 70a when shot by a golf club 73 as shown in Figure 50, but is affected up to the intermediate part 70b and the core 70c, thereby deforming the ball much more than the formal golf ball to absorb the impact by a full swing, reducing the ball speed down to half.
  • a golf ball 76 has a diameter and weight of a formal golf ball in the range from 41.15 mm to 42.67 mm and from 44.50 g to 45.92 g, and divided into 3 parts: a surface part 76a, an intermediate part 76b, and a core 76c.
  • the surface part 76a of the above mentioned golf ball is made of the same composite as a formal golf ball comprising rubber and filler, and the intermediate part 76b of softer and smaller gravity composite than the surface part 76a composite.
  • the core 76c comprises a harder and larger gravity composite than the composite of the surface part 76a such as iron, lead, etc.
  • the golf ball above has half flight distance of a formal golf ball when shot by a full swing as the ball shown in Figures 46.
  • Figures 53 and 54 show an embodiment of a golf ball designed to float on water.
  • a golf ball 77 is a sphere having a diameter of a formal golf ball in the range of from 41.15 mm to 42.67 mm.
  • the sphere is divided into three parts: a surface part 77a, an intermediate part 77b, and a core 77c.
  • the surface part 77a is made of the same composite as a formal golf ball comprising rubber and filler, the intermediate part 77b of a softer and smaller gravity composite than the surface part 77a (for example, foam object, foam polyethylene, foam polyurethane, etc.).
  • the core 77c is made of a softer and smaller gravity composite than the intermediate part 77b. Therefore, the golf ball 77 is designed to be gradually softer and lighter to the inner part.
  • the average gravity of the golf ball 77 is less than 1.0, that is, the ball 77 is set to 30 - 36 g to float on water.
  • the impact given to the ball by a full swing reaches the core 77c and absorbs the impact more gently than a formal golf ball, shortening the flight distance of the ball 77.
  • a smaller impact by a putter, etc. is absorbed at the surface part 77a, and the ball 77 can be carried with the touch to a formal golf ball.
  • the impact is not so large that most of the impact can be absorbed at the surface part 77a and the intermediate part 77b, carrying the ball with the touch of pitching a formal golf ball.
  • the golf ball 77 has the average gravity less than 1, the ball floats on water W as shown in Figure 55 when it is shot into the water W of a pond 80, and can be easily taken out of the pond 80 by only waiting for the ball coming ashore on the wind or by catching it with a pole or something. Therefore, neither players nor golf link managements have the trouble of taking out a mass of the golf balls 77 sunk at the bottom of ponds 80. Thanks to this property of the golf ball 77, the loss from lost balls and from ruining the views of the golf links can be eliminated.
  • the golf ball shown in Figures 58 through 60 is designed to have a shorter flight distance by providing a narrow hole in the ball.
  • the golf ball 81 has a diameter in the range larger than small (English size 4.1) and smaller than large (American size 4.3), and it weighs less than 1.6 ounces (46 g). These values are almost equal to a formal golf ball.
  • the golf ball 81 has narrow holes 82 in three diametrical axes which cross orthogonally to one another at the core. Therefore, there are 6 openings of the narrow holes 82 on the surface of the golf ball 81.
  • the sphere of the golf ball 81 is made of an intermediate part 84 covered by a surface part 83, and the inner part to the intermediate part 84 is made hollow.
  • the surface part 83 is made of the same hard plastics as a formal golf ball.
  • the intermediate part 84 is made of a material such as rubber and soft plastics of larger gravity, and the narrow holes 82 are formed to taper off from the core 85 to the surface 83.
  • the intermediate part above can comprise a plurality of layers.
  • the air in the core 85 of the golf ball 81 is enclosed firmly keeping constant pressure against the air rapidly passing over the surface of the golf ball 81 during its flight by a full swing of a golf club (hereinafter referred to as high-pressure air).
  • the hemi-sphere facing forward during the flight will include at least one hole of the 6 narrow holes 82 of the golf ball 81. Therefore, the difference of the pressure between the high-pressure air around the flying golf ball 81 and the air at the core of it causes the high-pressure air to flow into the golf ball 81 through the narrow holes 82.
  • the golf ball 81 is filled with the high-pressure air flowed into it and compressed, and then the high-pressure air is blown out of the golf ball 81 through narrow holes 82 other than the holes that led in the high-pressure air. During this process of the high-pressure air flowing into the ball and blown out of it, the golf ball will lose its kinetic energy, thereby shortening its flight distance.
  • the above golf ball 81 can be carried with the touch to a formal golf ball by a full swing of a wood club on a teeing ground or an iron club on a fair way because the weight of the golf ball 81 is almost equal to a formal golf ball.
  • its flight distance can be shortened by the composite of its intermediate part and the configuration of the narrow holes.
  • the touch of the golf ball 81 and the carrying distance by a putter on a green are similar to a formal golf ball.
  • the flight distance of a golf ball can be shortened by providing the surface of a ball with dimples in the appropriate form. That is, the ball comprises a sphere surface whereon a prescribed number of concaves are provided with an optional bottom shape.
