Abstract

A golf tee includes a ball seat portion on which a golf ball is placed; and a rod-shaped support shaft portion formed downward from the ball seat portion. The support shaft portion has a projection that is laterally formed on and projected from the support shaft portion. The ball seat portion and the support shaft portion are formed plane-symmetrically on a single plane including a central axis line of the support shaft portion and a point of the projection. In the single plane, a virtual plane including contact portion that contacts with a golf ball when the golf ball is placed on the ball seat portion and a central axis line of the support shaft portion form an obtuse angle on one side of the axis line and form an acute angle on the other side of the axis line.

Claims

exact text as granted — not AI-modified
1 . A golf tee comprising:
 a ball seat portion on which a golf ball is placed; and   a rod-shaped support shaft portion formed downward from the ball seat portion, wherein   the support shaft portion has a projection that is laterally formed on and projected from the support shaft portion at a part spaced apart from the ball seat portion;   the ball seat portion and the support shaft portion are formed plane-symmetrically on a single plane including a central axis line of the support shaft portion and a point of the projection;   in the single plane, a virtual plane including a contact portion that contacts with a golf ball when the golf ball is placed on the ball seat portion and a central axis line of the support shaft portion form an obtuse angle on one side of the axis line and form an acute angle on the other side of the axis line; and   the projection is formed on and projected from a side on which the obtuse angle is formed.   
     
     
         2 . The golf tee according to  claim 1 , wherein the obtuse angle is between 100 degrees and 120 degrees, and the acute angle is between 60 degrees and 80 degrees. 
     
     
         3 . The golf tee according to  claim 2 , wherein the obtuse angle is between 105 degrees and 108 degrees, and the acute angle is between 72 degrees and 75 degrees. 
     
     
         4 . The golf tee according to  claim 1 , wherein the projection is formed in a position closer to the ball seat portion than a middle height position of the support shaft portion. 
     
     
         5 . The golf tee according to  claim 2 , wherein the projection is formed in a position closer to the ball seat portion than a middle height position of the support shaft portion. 
     
     
         6 . The golf tee according to  claim 3 , wherein the projection is formed in a position closer to the ball seat portion than a middle height position of the support shaft portion. 
     
     
         7 . The golf tee according to  claim 1 , wherein the projection is fin-shaped. 
     
     
         8 . The golf tee according to  claim 2 , wherein the projection is fin-shaped. 
     
     
         9 . The golf tee according to  claim 3 , wherein the projection is fin-shaped. 
     
     
         10 . The golf tee according to  claim 4 , wherein the projection is fin-shaped. 
     
     
         11 . The golf tee according to  claim 5 , wherein the projection is fin-shaped. 
     
     
         12 . The golf tee according to  claim 6 , wherein the projection is fin-shaped. 
     
     
         13 . The golf tee according to  claim 7 , wherein a curved concave portion is formed from a lower part of the projection to the support shaft portion. 
     
     
         14 . The golf tee according to  claim 8 , wherein a curved concave portion is formed from a lower part of the projection to the support shaft portion. 
     
     
         15 . The golf tee according to  claim 9 , wherein a curved concave portion is formed from a lower part of the projection to the support shaft portion. 
     
     
         16 . The golf tee according to  claim 10 , wherein a curved concave portion is formed from a lower part of the projection to the support shaft portion. 
     
     
         17 . The golf tee according to  claim 11 , wherein a curved concave portion is formed from a lower part of the projection to the support shaft portion. 
     
     
         18 . The golf tee according to  claim 12 , wherein a curved concave portion is formed from a lower part of the projection to the support shaft portion.
