Claims

[Claims for Utility Model Registration] (1) A hollow spherical rubber tube filled with compressed air, a reinforcing cloth layer covering the surface of the tube, and adhesion to the cloth layer either directly or through a thin rubber layer. In a ball game ball having a leather layer,
The cloth layer is formed by dividing the spherical surface into six regular sides to obtain an equilateral quadrilateral, and dividing the equilateral quadrilateral into four by two dividing lines perpendicular to the midpoint of each side. A ball game ball characterized in that a cloth is cut into a rectangular shape and 24 pieces of the four-sided cloth are sewn together to form a spherical shape. (2) The ball game ball according to claim 1, wherein the grain direction of the cloth piece is parallel to one side of the cloth piece. (3) A utility model characterized in that the above-mentioned pieces of cloth are arranged so that the grain directions of the ground thereof are set in the same direction within the above-mentioned equilateral quadrilaterals, and are orthogonal to each other between adjacent equilateral quadrilaterals. Scope of registration claims 2nd
Balls for ball games as described in section. (4) The above-mentioned piece of cloth is arranged so that its ground grain direction is perpendicular to the ground grain direction of other adjacent cloth pieces, as set forth in claim 2 of the utility model registration claim. Ball for ball games. (5) The ball for a ball game according to claim 1, wherein the grain direction of the cloth piece is parallel to one diagonal line of the cloth piece. (6) Utility model registration claim 5, characterized in that the above-mentioned piece of cloth is arranged so that its ground grain direction is orthogonal to the ground grain direction of other adjacent pieces of cloth.
Ball for spherical ball as described in section.
