Abstract
A golf ball includes a ball cover including a first and second hemispheric cups attached to each other to form a hollow spheroid and a solid ball core covered by the ball cover. Each of the first and second hemispheric cups has two semi-conical engagement edges fittingly engaged with two semi-conical connection edges of the other hemispheric cup so as to integrally unite the first hemispheric cup and the second hemispheric cup together to form the ball cover.
Claims20
A golf ball, comprising:
- a ball cover, having a S-shaped seam continuously formed on an outer surface of said ball cover and comprising a first hemispheric cup and a second hemispheric cup attached to said first hemispheric cup edge to edge to form a hollow spheroid;
- and
- a solid ball core covered by said ball cover;
- wherein said first hemispheric cup has two identical first semi-conical engagement edges symmetrically outwardly projecting at two sides thereof and two identical first semi-conical connection edges inwardly projecting between said two first semi-conical engagement edges, wherein said two first semi-conical engagement edges are symmetrically and continuously extended between said two first semi-conical connection edges so as to form a continuous first joint edge for said first hemispheric cup;
- wherein the second hemispheric cup has two identical second semi-conical engagement edges symmetrically outwardly projecting at two sides thereof and two identical second semi-conical connection edges inwardly projecting between said second first semi-conical engagement edge, wherein said two second semi-conical engagement edges are symmetrically and continuously extended between said two second semi-conical connection edges so as to form a continuous second joint edge for said second hemispheric cup;
- wherein a cone height of each of said first and second semi-conical engagement edges is equal to a cone height of each of said first and second semi-conical connection edges, and a size and shape of said first hemispheric cup and the second hemispheric cup are identical and symmetrical, wherein said two second semi-conical engagement edges are fittingly engaged with said two first semi-conical connection edges respectively while said two second semi-conical connection edges are fittingly engaged with said two first semi-conical engagement edges respectively, so as to integrally unite said first hemispheric cup and said second hemispheric cup together to form said ball covert;
- wherein said S-shaped seam are formed along a connection between said two second semi-conical engagement edges and said two first semi-conical connection edges respectively and a connection between said two second semi-conical connection edges and said two first semi-conical engagement edges respectively.

A golf ball, comprising:
- a ball cover having a hollow spherical shaped;
- and
- a solid ball core, which is covered by said ball cover, having a S-shaped line continuously formed on an outer surface of said ball core and comprising a first core body and a second core body attached to said first core body to form a spheroid;
- wherein said first core body has a first joint portion which comprises two identical first semi-conical engagement tongues symmetrically projecting at two sides thereof so as to define two identical first semi-engagement grooves symmetrically indented between said two first semi-conical engagement tongues, wherein said two first semi-conical engagement tongues respectively define two first conically curved tongue surfaces symmetrically facing with each other, and said two first semi-conical engagement grooves respectively define two first conically curved groove surfaces symmetrically and continuously extended between said two first conically curved tongue surfaces, so as to form a continuous first joint surface for said first joint portion;
- wherein said second core body has a second joint portion which comprises two identical second semi-conical engagement tongues symmetrically projecting at two sides thereof so as to define two identical second semi-engagement grooves symmetrically indented between said two second semi-conical engagement tongues, wherein said two second semi-conical engagement tongues respectively define two second conically curved tongue surfaces symmetrically facing with each other, and said two second semi-conical engagement grooves respectively define two second conically curved groove surfaces symmetrically and continuously extended between said two second conically curved tongue surfaces, so as to form a continuous second joint surface for said second joint portion;
- wherein a cone height of each of said first and second semi-conical engagement tongues is equal to a cone height of each of said first and second semi-conical engagement grooves, and thus a size of the shape of said first joint portion and said second joint portion are identical and symmetrical, so that said two second semi-conical engagement tongues are fittingly engaged in said two first semi-conical engagement grooves respectively while said first semi-conical engagement tongues are fittingly engaged in said two second semi-conical engagement grooves respectively, so as to integrally unite said first joint portion and said second portion together to form said spheroid of said solid ball core;
- wherein said S-shaped line is formed along a connection between said two second semi-conical engagement tongues and said two first semi-conical engagement grooves respectively and a connection between said first semi-conical engagement tongues and said two second semi-conical engagement grooves respectively.
