Golf ball having marking

Abstract

The present invention provides a golf ball having, on a ball surface, a plurality of groups of markings that are visually recognizable at the same time, one of the groups of markings including a first marking that includes a character sequence provided along a large circle, a second marking that includes lines horizontally extending above and below the first marking, and a third marking that is a line that extends in a direction perpendicular to the second marking and is present at either a left end or a right end of the group of markings, a tip end of the group of markings on a side opposite to the end where the third marking is present having a pointed portion.

1 . A golf ball having, on a ball surface, a plurality of groups of markings that are visually recognizable at the same time, one of the groups of markings including a first marking that includes a character sequence provided along a large circle, a second marking that includes lines horizontally extending above and below the first marking, and a third marking that is a line that extends in a direction perpendicular to the second marking and is present at either a left end or a right end of the group of markings, and, further, a tip end of the group of markings on a side opposite to the end where the third marking is present having a pointed portion. 
     
     
         2 . The golf ball according to  claim 1 , wherein the character sequence of the first marking is present within a strip-shaped marking. 
     
     
         3 . The golf ball according to  claim 2 , wherein a tip end of the strip-shaped marking includes a pointed portion. 
     
     
         4 . The golf ball according to  claim 1 , wherein the character sequence of the first marking includes at least one number. 
     
     
         5 . The golf ball according to  claim 1 , wherein a color of the character sequence of the first marking is the same as a surface color of the ball. 
     
     
         6 . The golf ball according to  claim 1 , wherein the lines horizontally extending on the upper side and the lower side in the second marking are parallel to each other. 
     
     
         7 . The golf ball according to  claim 1 , wherein in the pointed portion arranged on the side opposite to the third marking, an angle of pointing of the pointed portion is 90±30°. 
     
     
         8 . The golf ball according to  claim 1 , wherein in the pointed portion arranged on the side opposite to the third marking, an angle of pointing of the pointed portion is 90±15°. 
     
     
         9 . The golf ball according to  claim 1 , wherein in the lines horizontally extending on the upper side and the lower side in the second marking, the thickness of the line on the upper side is the same as the thickness of the line on the lower side. 
     
     
         10 . The golf ball according to  claim 2 , wherein a relationship of the thicknesses of the strip in the first marking, the lines on the upper side and the lower side in the second marking, and the line in the third marking satisfies the following expression:
 the lines on the upper side and the lower side in the second marking<the line in the third marking<the strip in the first marking.   
     
     
         11 . The golf ball according to  claim 1 , wherein markings formed on the ball surface include a face marking and a side marking, and the group of markings including the first, second, and third markings is a side marking. 
     
     
         12 . The golf ball according to  claim 1 , wherein face markings are present at two locations.
