Title: Tubular golf tee

Description:
1. FIELD OF THE INVENTION  
      The present invention relates to a golf tee.  
     2 DESCRIPTION OF THE PRIOR ART  
      Heretofore most golf tee designs limited the golfer to a single solid cylindrical structure which has a ball placement part at one end and a shaft tapering down to a sharp point at other end. If the golfer, using different clubs to strike the ball would require ball placement at an increased height over and above what the present tee would provide, the golfer is then required to carry longer tees in addition to the present tees. Having to carry more than one size tee is cumbersome for the golfer. Another disadvantage, the sharp point of the solid tee is a hazard to the golfer who may accidentally be punctured with the handling of the said solid golf tee. Some patented golf tees attempt to overcome these problems but each of them has a number of other disadvantages. U.S. Pat. No. 2,011,203 issued to Seiki (1935) and U.S. Pat. No. 5,085,431 issued to McGuire (1992) have tubular structures but they require an accessory to enable the installation of the tee into the ground. Having to carry one or more added items in addition to the golf tee is cumbersome and installation of the said tee is time consuming. U.S. Pat. No. 2,747,768 issued to Raines (1956), U.S. Pat. No. 2,589,763 issued to Barrett (1952) and U.S. Pat. No. 4,948,130 issued to Rydborn (1990) include the provision for nesting the tee, but the patented tees have a sharp point which is a puncture hazard to the golfer.  
     3. SUMMARY OF THE INVENTION  
      The present inventor has found the drawbacks of the conventional golf tee and invented the tubular golf tee for stably supporting the golf ball. 
    
    
      It is an object of the present invention to provide a golf tee which is all inclusive.  
      It is another object of the present invention to provide a golf tee that has a blunt end for inserting into the ground and not be a hindrance to the golfer as the sharp point of a conventional golf tee can be.  
      It is also an object of the present invention to provide a golf tee that can be nested so that the height of the golf ball can be raised to suit the golfer.  
      It is also an object of the present invention to provide a golf tee which is easily manufactured of plastic by the injection molding process.
