Golf tee-accessory assembly

Abstract

A golf tee-accessory assembly for positioning a golf ball at a predetermined height, comprising a golf tee, the golf tee having upper and lower ends and a shaft of substantially uniform diameter connecting the ends, the upper end having a cup of a substantially uniform diameter for receiving a golf ball, the lower end being tapered for insertion into a playing surface; and a hollow, cylindrical sleeve member mounted on and surrounding an upper portion of the shaft of the tee, the sleeve member having a diameter and wall thickness providing, at the lower end of the sleeve, a ground-engaging surface surrounding the shaft of the tee for limiting the depth by which the lower end of the tee's shaft penetrates the ground.

1 . A golf tee-accessory assembly for positioning a golf ball at a predetermined height, comprising: 
 a) a golf tee, the golf tee having upper and lower ends and a shaft of substantially uniform diameter connecting the ends, the upper end having a cup of a substantially uniform diameter for receiving a golf ball, the lower end being tapered for insertion into a playing surface; and    b) a hollow, cylindrical sleeve member mounted on and surrounding an upper portion of the shaft of the tee, the sleeve member having a diameter at least as great as said shaft but not greater than said diameter of said cup and wall thickness providing, at the lower end of the sleeve, a ground-engaging surface surrounding the shaft of the tee for limiting the depth by which the lower end of the tee's shaft penetrates the ground.    
   
   
       2 . The golf tee-accessory assembly of  claim 1 , wherein said sleeve member comprises a resilient material.  
   
   
       3 . The golf tee-accessory assembly of  claim 1 , wherein said sleeve member comprises soft plastic.  
   
   
       4 . The golf tee-accessory assembly of  claim 1 , wherein said sleeve member comprises hard plastic.  
   
   
       5 . The golf tee-accessory assembly of  claim 1 , wherein said sleeve member comprises biodegradable plastic.  
   
   
       6 . The golf tee-accessory assembly of  claim 1 , wherein said sleeve member is color-coded.  
   
   
       7 . A golf tee-accessory assembly for positioning a golf ball at a predetermined height, comprising: 
 a) a golf tee, the golf tee having upper and lower ends and a shaft of substantially uniform diameter connecting the ends, the upper end having a cup of a substantially uniform diameter for receiving a golf ball, the lower end being tapered for insertion into a playing surface; and    b) a sleeve member, said sleeve member having: 
 i) a generally cylindrical shape defining a generally cylindrical hole therethrough dimensioned to couple with said shaft of said tee;  
 ii) a diameter at least as great as said diameter of said shaft but not greater than said diameter of said cup, whereby said sleeve member can act as a stop that determines the height of said cup above a playing surface; and  
 iii) being of a predetermined length, not exceeding the distance between said cup and said tapered end of said tee.
