Soccer ball

Abstract

Disclosed herein is a soccer ball, which is made by sewing 12 pentagon panels and 20 hexagon panels, and more particularly, the soccer ball utilizes regular pentagon panels and equiangular hexagon panels, both of which have the same area. By doing so, when being inflated, the regular pentagon panels and the equiangular hexagon panels can protrude evenly. The soccer ball of the present invention has the advantages in that the problems of irregular bounce and deteriorated speed and revolution properties are solved and so the ball can be used for adult or official games, the air resistance and the friction are much reduced, and so the revolution speed becomes increased and the abrasion of the ball is reduced.

1 . A soccer ball comprising: 
 a spherical outer cover formed by sewing the respective borders of 12 pentagon panels and 20 hexagon panels, one pentagon panel being connected with five hexagon panels, while one hexagon panel being connected with three pentagon panels and three other hexagon panels, and    a spherical elastic tube, which is housed inside the outer cover to provide the ball with elasticity, the elastic tube being spherically inflated by injecting air therein,    wherein the pentagon panel is formed in a regular pentagonal shape, and the area of the hexagon panel is the same as that of the pentagon panel.    
   
   
       2 . The soccer ball of  claim 1 , wherein the hexagon panel is an equiangular hexagon which is constituted by three longer sides which have the same length and three shorter sides which also have the same length, the longer sides and the shorter sides being alternately connected with one another, and the confronting sides among the longer and shorter sides being disposed in parallel with one another, 
 wherein the ratio of the longer sides “a” connected with sides of the regular pentagon panels to the shorter sides “b” not connected with the sides of the regular pentagon panels is 1:0.64(b=0.64a).
