Golf bag with a stable base

Abstract

A golf bag with a base having protrusion forming regions at a first section ranging from 30 to 60 degrees from a reference line, a second section ranging from 120 to 150 degrees from the reference line, a third section ranging from 210 to 240 degrees from the reference line, and a fourth section ranging from 300 to 330 degrees from the reference line. At each of the protrusion forming regions, one or more protrusions are formed to prevent the golf bag from rotating and falling over. A pair of tangents drawn from two of the protrusions in the front-rear direction and a pair of tangents drawn from two of the protrusions in the lateral direction pass outside of a base peripheral edge. Auxiliary protrusions may also be formed on the base at the positions of 90 degrees and 270 degrees from the reference line. All tangents linking the adjacent protrusions and all tangents linking the adjacent protrusion and auxiliary protrusion may pass outside of the base peripheral edge.

1 . A golf bag, comprising: 
 a base ( 1 ) having protrusion forming regions ( 5 ) at a first section ( 21 ) ranging from 30 to 60 degrees from a reference line, a second section ( 22 ) ranging from 120 to 150 degrees from the reference line, a third section ( 23 ) ranging from 210 to 240 degrees from the reference line, and a fourth section ( 24 ) ranging from 300 to 330 degrees from the reference line;    at least one protrusion ( 2 ) formed within each of the protrusion forming regions and having a protruding length; and    an auxiliary protrusion ( 3 ) formed on the base between the first and second sections of the protrusion forming regions and another auxiliary protrusion on the base between the third and fourth sections of the protrusion forming regions to support the golf bag in a direction perpendicular to the reference line, the auxiliary protrusions having a protruding length shorter than the protruding length of the at least one protrusion within one of the protrusion forming regions.    
   
   
       2 . The golf bag according to  claim 1 , wherein at least a pair of tangents ( 11 ) drawn from the protrusions ( 2 ) in the front-rear direction and at least a pair of tangents ( 12 )) drawn from the protrusions ( 2 ) in the lateral direction pass outside of a base peripheral edge ( 6 ).  
   
   
       3 . The golf bag according to  claim 1 , wherein the protruding length (L) of the protrusion ( 2 ) from a base peripheral edge ( 6 ) is from 10 mm to 50 mm.  
   
   
       4 . The golf bag according to  claim 2 , wherein the protruding length (L) of the protrusion ( 2 ) from the base peripheral edge ( 6 ) is from 10 mm to 50 mm.  
   
   
       5 - 8 . (canceled)  
   
   
       9 . The golf bag according to  claim 1 , wherein all tangents ( 14 ) linking adjacent protrusions ( 2 ) or auxiliary protrusions pass outside of a base peripheral edge ( 6 ).  
   
   
       10 . The golf bag according to  claim 2 , wherein all tangents ( 14 ) linking adjacent protrusions ( 2 ) or auxiliary protrusions pass outside of the base peripheral edge ( 6 ).  
   
   
       11 . The golf bag according to  claim 3 , wherein all tangents ( 14 ) linking adjacent protrusions ( 2 ) or auxiliary protrusions pass outside of the base peripheral edge ( 6 ).  
   
   
       12 . The golf bag according to  claim 4 , wherein all tangents ( 14 ) linking adjacent protrusions ( 2 ) or auxiliary protrusions pass outside of the base peripheral edge ( 6 ).  
   
   
       13 - 16 . (canceled)  
   
   
       17 . The golf bag according to  claim 1 , wherein the reference line is a line passing through the center of the base and a point on a base peripheral edge that is closest to a grip of the golf bag.  
   
   
       18 . The golf bag according to  claim 1 , wherein the protruding length of the auxiliary protrusions is radially shorter than the protruding length of the at least one protrusion within one of the protrusion forming regions.
