2 Functions of the upper piece:

	(1) Vertical locking of the hinge joint. When pushed downwards into the ground the tee automatically becomes stiff and blocks Driver Tee's hinged effect. However when teed up this releases again.
	(2) Protection. Special formed head protects both the Driver Tee and the club head. The hinged joint is protected due to the closure on the hitting side.
	(3) Stabilizer. The stabilization in the upright position ensures a secure teeing of the ball in the optimum position.
	(4) Free for advertising.
	(5) Hinged joint for hitting the ball without resistance.
