摘要:
A golf ball (70,76) for miniature golf links is formed of a three layer structure; a surface part (70a, 76a), intermediate part (70b,76b) and core (70c,76c). The surface part (70a,76a) is made of the same composite of rubber and filler as a formal golf ball. The intermediate part (70b,76b) is made of a softer material than the surface part (70a,76a). The core (70c,76c) may be solid or hollow. Various types of concave or convex structures may be formed on the surface of the ball.
摘要:
The golf ball consists in a ball with diametric holes, perforations or orifices through it, spaced at appropriate distances on the surface and with a hollow centre created by the crossing of the through orifices, or by an added spherical chamber, it can use also a central spherical compact zone using in this case tangential holes to said central zone.

摘要:
A mini-golf course wherein golf similar to a formal golf can be played in an area smaller than a formal golf course. The mini-golf course is constituted of a plurality of tee grounds and a plurality of putting greens having holes corresponding to the tee grounds. In each of respective golf courses, there are a long course, a middle course and a short course. Each of the courses can be used as an out-course, an in-course or a center course a plurality of times. Golf balls are formed so as to have shorter flying distances. Score cards each have score write-in columns corresponding to reference stroke count columns, and, a plurality of score write-in columns are provided so that each of the courses can be used as an out-course, in-course or center course.
摘要:
A golf ball-forming composition, golf balls prepared from the composition and the process for preparing thereof. The golf ball-forming composition is composed of the following ingredients: polyvinyl alcohol resin 5-80 wt%, filler 0-90 wt%, natural polymer material 0-60wt%, and plasticizer 5-50 wt%. The filler is fillers conventionally used by the person skilled in the art; the natural polymer material is fibrous substance or polysaccharide based substance; and the plasticizer is substances conventionally used by the person skilled in the art. The golf ball-forming composition is water soluble and biodegradable. The water soluble and biodegradable golf ball has a hollow inside, and the surface of the ball is disposed with at least one through hole communicating with the hollow. When the golf ball is hit into water, water will enter the hollow via the through hole, thereby increasing the contact area between water and the ball and accelerating the dissolution of the ball, so that the ball may be completely biodegraded in the environment eventually.
摘要:
A golfball comprising a shell of a plastic material, which shell is seamless and encloses a hollow core. The core preferably contains a gas with a pressure above atmospheric pressure. The invention also relates to a process for manufacturing such a golfball by means of injection moulding, whereby gas is injected in the plastic material in the mould cavity, preferably by means of a moveable gas injection needle that can close off. The invention further relates to a device for manufacturing the above described golfball.

摘要:
Golf balls with a reduced flight path are disclosed. In some cases, foam incorporated into a middle layer increases impact absorption and reduces a ball's flight path. In other cases, a dimple pattern may be selected to reduce a ball's flight path. In other instances, a parachute or other drag inducer may be deployed as a result of striking the ball to induce drag and minimize the ball's flight path.
