Adjustable golf tee set

Abstract

An adjustable golf tee set is disclosed to include a tee nail for fastening to the ground in a golf course to support a golf ball for hitting, a base block for supporting the tee nail stably on the ground, and a connecting cord for securing the support to a ground anchor. A plurality of annular spacer blocks of different thicknesses are selectively used and mounted on the base block around a pointed shank of the tee nail to adjust the elevation of the tee nail subject to different ball-striking needs.

1 . An adjustable golf tee set comprising:
 a tee nail, the tee nail having a cup-like head for holding a golf ball and a pointed shank downwardly extending from a bottom side of the cup-like head for fastening to the ground; and   a support for mounted around the pointed shank of the tee nail at a bottom side of the cup-like head to support the teen nail on the ground, the support comprising a base block and at least one annular spacer block, the base block and the at least one annular spacer block each having a center through hole for the insertion of the pointed shank of the tee nail.   
   
   
       2 . The adjustable golf tee set as claimed in  claim 1 , wherein the pointed shank of the tee nail comprises a plurality of longitudinal locating ribs arranged around the periphery; the base block and the at least one annular spacer block each have a plurality of longitudinal locating grooves disposed in the respective center through hole for receiving the longitudinal locating ribs of the pointed shank to prohibit rotation of the tee nail relative to the support. 
   
   
       3 . The adjustable golf tee set as claimed in  claim 1 , wherein the pointed shank of the tee nail comprises a plurality of longitudinal locating grooves arranged around the periphery; the base block and the at least one spacer block each have a plurality of longitudinal locating ribs disposed in the respective center through hole for engaging the longitudinal locating grooves of the pointed shank to prohibit rotation of the tee nail relative to the support. 
   
   
       4 . The adjustable golf tee set as claimed in  claim 1 , wherein the base block has a bearing portion upwardly extending from a top side around the center through hole thereof for supporting the at least one annular spacer block. 
   
   
       5 . The adjustable golf tee set as claimed in  claim 1 , wherein the base block has a plurality of wire holes for the mounting of a connecting cord selectively to securing the base block to a ground anchor. 
   
   
       6 . The adjustable golf tee set as claimed in  claim 1 , wherein the at least one annular spacer block includes a plurality of annular spacer blocks having different thickness for selectively fastening to the pointed shank of the tee nail to support the cup-like head of the tee nail above the base block. 
   
   
       7 . The adjustable golf tee set as claimed in  claim 1 , wherein the tee nail has a plurality of locating grooves arranged on the periphery of the pointed shank at different elevations; the support comprises at least one retaining pin mounted in the base block and partially extending out of the base block and movable in and out of the center through hole of the base block for selectively engaging the locating grooves of the tee nail to lock the base block to the pointed shank of the tee nail at a selected elevation, and spring means mounted in the base block and adapted to force the at least one retaining pin into engagement with the locating grooves of the tee nail. 
   
   
       8 . The adjustable golf tee set as claimed in  claim 1 , wherein the tee nail has a plurality of locating grooves arranged on the periphery of the pointed shank at different elevations; the support comprises a U-clamp fixedly mounted in the base block, said U-clamp having two clamping spring arms for selectively engaging the locating grooves to secure the base block to the pointed shank of the tee nail at a selected elevation.
