摘要： PROBLEM TO BE SOLVED: To improve the sense of touch with respect to a sport ball. SOLUTION: The ball 10 is provided with inner layers 12 and plural spacer pannels 16 extending outwards from the inner layers 12 in a radius direction. The spacer pannels are provided with an inner endge part 18 positioned so as to be adjacent to the inner layer, a free outer edge part 20 and a horizontal direction side edge part 22 which is made to be a waffle shape between the both edge parts 18 and 22 and is connected to the horizontal direction side edge part of the adjacent spacer pannel. Therefore, plural recessed parts extending downwards from the free outer edge parts are formed so that intermediate layers 14 are provided, which are provided with outer surfaces formed from the respective free outer edge parts so as to form grid-pattern recessions. Outer layers 16 which are adjacent to the outer surfaces of the intermediate layers so as to close-up an air pocket are provided in the respective recessions.

摘要： PROBLEM TO BE SOLVED: To provide a high restitution coefficient, controlled moment of inertia and a high spin velocity at a short shot. SOLUTION: The golf ball is structured so as to be comprised of a solid core and a cover surrounding the core. In such case, the core contains a central core layer and an outside core layer surrounding the central core layer, the central core layer has a specific gravity significantly differing from the outside core layer by more than 0.1, and the cover contains an inside cover layer formed by covering the core and an outside cover layer surrounding the inside cover layer, and the Shore D hardness of the outside cover layer is lower than the inside core layer and 55 or lower.

摘要： A golf ball of improved playing characteristics weighing no more than 1.62 ounces and having a mean outside diameter of at least 1.70 inches. A dimple pattern on the surface of the ball may include a plurality of dimples which have different diameters. The dimples cover at least 70% of the surface of the ball. A core and cover are used which provide a finished ball having a coefficient of restitution between 0.790 and 0.830.

摘要： An improved golf ball having a coefficient of restitution of at least 0.700 and comprising a hollow, spherical shell of a deformable polymeric material which is filled with either a liquid or a unitary, non-cellular core of a material which, at the time of introduction into the shell, is a liquid. The spherical shell may be solid or cellular. The core material may be added through a hole in the shell as a liquid, a gel or a melt. In the preferred embodiment, the spherical shell is formed from two half shells which are bonded to each other. The mating edges of the half shells may have surface configurations which maximize their contact area.

摘要： A dimple configuration for a golf ball having a dimple-free equator wherein each hemisphere has substantially the same dimple pattern, the dimple pattern in each hemisphere comprising a total of 201 dimples with a dimple located at the pole and a first set of five adjacent triangles, with one vertex of each triangle being at the pole dimple and the sides of the triangles opposite the pole being spaced a predetermined distance from the equator. The pattern further comprises a second set of five triangles smaller than the first set of triangles and equally spaced between the first set of triangles and the equator. Each of the second set of triangles has a vertex common with adjacent ones of the first set of triangles. The legs of all the triangles contain adjacent dimples and the area within the large triangles and between the small triangles is also filled with dimples. Three different diameters of dimples are used within the pattern.

摘要： This invention is an improved golf ball (142) comprising a hollow, spherical shell (112) of a polymeric material; a unitary, noncellular core (124) of a material which, at the time of introduction into the shell, is a liquid; and a spherical cover (140) over the center (112). The spherical shell (112), as opposed to the core (124), is primarily responsible for the high initial velocity obtained when the golf ball (142) is struck by the golf club so as to allow the golf ball (142) to be driven long distances both in the air and on the ground when it lands. In one alternate embodiment (146), the shell is of a one-piece, blow molded construction (152).
