Abstract

Golf ball comprising a core and a cover, wherein the core includes between 2 and 20 smaller spheres that are surrounded by a second core composition having at least one different physical property than the composition(s) forming the smaller spheres. The smaller spheres can be entirely surrounded by the second core composition; or, at least two smaller adjacent spheres may each be partially surrounded by the second core composition while also being in partial contact with each other.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A golf ball comprising:
 a cover; and   a core surrounded by the cover and defining a core center point, the core comprising:
 a plurality of spheres formed from a first composition, each of the plurality of spheres defining a sphere center point; and 
 a second composition, different from the first composition, surrounding the plurality of spheres, the second composition formed in a shape having a spherical outer surface that defines a plurality of diameters through the core center point, 
   wherein the second composition occupies the core center point and at least one of the plurality of diameters of the spherical outer surface follows a linear path through the core that does not intersect any of the plurality of spheres such that the linear path extends only through the second composition.   
     
     
         2 . The golf ball of  claim 1 , wherein the plurality of spheres are arranged such that each of the sphere center points are equally spaced from the core center point. 
     
     
         3 . The golf ball of  claim 1 , wherein the plurality of spheres are arranged such that all of the sphere center points are located in the same plane. 
     
     
         4 . The golf ball of  claim 3 , wherein the plurality of spheres are arranged such that each of the sphere center points are equally spaced from the core center point. 
     
     
         5 . The golf ball of  claim 1 , wherein the plurality of spheres are arranged such that a first subset of the sphere center points are located in a first plane and a second subset of the sphere center points are located in a second plane, wherein all of the sphere center points are in the first subset or the second subset. 
     
     
         6 . The golf ball of  claim 5 , wherein the first plane is parallel to the second plane. 
     
     
         7 . The golf ball of  claim 5 , wherein the plurality of spheres are arranged in a tetrahedron shape. 
     
     
         8 . The golf ball of  claim 7 , wherein the tetrahedron shape defines a tetrahedron center point, wherein the tetrahedron center point is located at the core center point. 
     
     
         9 . The golf ball of  claim 1 , wherein the plurality of spheres are arranged in a shape having at least one axis of rotational symmetry. 
     
     
         10 . The golf ball of  claim 9 , wherein the plurality of spheres are arranged in a shape having four axes of rotational symmetry. 
     
     
         11 . The golf ball of  claim 1 , wherein each of the plurality of spheres is positioned in contact with at least one other sphere of the plurality of spheres. 
     
     
         12 . The golf ball of  claim 11 , wherein each of the plurality of spheres is positioned in contact with two other spheres of the plurality of spheres such that the first composition is formed in a continuous that band extends circumferentially around the core center point. 
     
     
         13 . The golf ball of  claim 1 , wherein the first composition has a first hardness and the second composition has a second hardness, wherein the first hardness is less that the second hardness. 
     
     
         14 . The golf ball of  claim 13 , wherein each of the plurality of spheres have a diameter of between 0.3 in. and 0.75 in. 
     
     
         15 . A golf ball comprising:
 a cover; and   a core surrounded by the cover and defining a core center point, the core comprising:
 a plurality of spheres formed from a first composition; and 
 a second composition, different from the first composition, surrounding the plurality of spheres, 
   wherein the first composition has a first hardness and the second composition has a second hardness, wherein the first hardness is less that the second hardness,   wherein the second composition occupies the core center point.   
     
     
         16 . The golf ball of  claim 15 , wherein each of the plurality of spheres has a diameter of between 0.3 in. and 0.75 in. 
     
     
         17 . The golf ball of  claim 15 , wherein the second hardness is greater than the first hardness by about 12-22 Shore C hardness points. 
     
     
         18 . The golf ball of  claim 15 , wherein the second hardness is greater than the first hardness by at least 15 Shore C hardness points. 
     
     
         19 . The golf ball of  claim 15 , wherein the plurality of spheres are arranged in a shape having at least four axes of rotational symmetry. 
     
     
         20 . The golf ball of  claim 15 , wherein each of the plurality of spheres is positioned in contact with at least one other sphere of the plurality of spheres.
