Golf tee device

Abstract

A golf tee device comprises a tee ( 4 ) which has external buttress threading ( 5 ) for insertion into the corresponding threading ( 2 ) of a housing ( 1 ) so that the height of the tee can be adjusted. The top of the threading indicates that the tee ( 4 ) is at its maximum working height.

1 . A golf tee device comprising a tee member removably supported in a holder member, wherein the tee member is movable in a continuous manner in a substantially vertical direction relative to the holder member, and wherein there is provided means to prevent movement between the tee member and the holder member on striking of a golf ball supported by the tee member.  
   
   
       2 . A device according to  claim 1 , wherein the means to prevent movement prevents axial movement of the tee member relative to the holder member.  
   
   
       3 . A device according to  claim 1 , wherein the tee member is supported by means of threading provided along at least a part of the length of the exterior of the tee member and/or at least a part of the length of the interior of the holder member.  
   
   
       4 . A device according to  claim 3 , wherein the threading is buttressed in form.  
   
   
       5 . A device according to  claim 4 , wherein the buttress threading has a first surface at an acute angle to the axis of the tee and a second surface substantially perpendicular to the axis.  
   
   
       6 . A device according to  claim 5 , wherein the first surface of the buttress threading is at an angle of 30° to 60° to the axis of the tee.  
   
   
       7 . A device according to  claim 6 , wherein the first angle is substantially 45°.  
   
   
       8 . A device according to  claim 1 , comprising means to prevent full insertion of the tee member into the holder member.  
   
   
       9 . A device according to  claim 1 , wherein the tee member is longer than the holder member.  
   
   
       10 . A device according to  claim 1 , comprising means for indicating when the tee member is at its maximum workable height.  
   
   
       11 . A device according to  claim 10 , wherein the means for indicating when the tee member is at its maximum workable height comprises the topmost part of the threading of the tee member.
