Abstract
A golf tee with tactile height adjustment includes a cup formed to receive and retain a golf ball. From the underside of the cup, a continuously threaded shaft extends and is formed with a longitudinal flat portion. A stop is formed with a threaded bore having threads complementary to those threads formed on the threaded shaft. Extending outward from the flat portions of the shaft are tactile engagement posts formed to engage the threads of the threaded stop as it threads along the threaded shaft. The engagement posts provide for the self cleaning of the threads of the golf tee, and also provides a tactile response including a distinct resistance to rotation of the threaded stop when the stop contacts the tactile posts. More specifically, when the threaded stop is positioned on the shaft adjacent a engagement post, the rotation of the stop is more difficult than rotation at a position on the shaft having no engagement post. In this manner, the user may tactilely determine whether the positioning disc is adjacent a tactile engagement post or between tactile engagement posts.
